In 10 minutes, she had a scheduled appointment with Mrs. Henson and her son. Dr. Wood was a pretty woman in her late forties who has worked in a private sexual health clinic. Kate Henson and her son Erik lived alone. Kate Henson divorced five years ago, was now at age 44. She was 5'6", and had a beautiful face with brown short hair, and a dress size of between 12 and 14. She had size 38DD boobs, a nice full rear end, and good curves. Erik was 5'8," average to heavy build, and was handsome with brown hair. However, he was still a virgin at the age of 18. Dr. Wood wanted to get some rest and prepare herself for the next appointment. She had always been interested in the relationship between mother and son. A few minutes later, the phone rang and the nurse said that Mrs. Henson and her son arrived. Then a door opened and they came to her office. Dr. Wood looked at Mrs. Henson and then her son. She was pleased by what she saw. Mrs. Henson was a large lady, but not overweight in any sense - just gorgeous, natural curves from head to toe. Her son was a handsome young man, tall and well built. "Hello, my name is Dr. Wood. It's Erik, isn't it?" she said, looking directly at Erik who nodded. Then, she turned to Mrs. Henson. "Mrs. Henson, do you want to sit in on our consultation?" the doctor asked. It was one of her test questions. Mrs. Henson hesitated a bit, looked at her son and then confirmed. Dr. Wood was satisfied, she received a confirmation through this gesture that their relationship was more than the usual relationship of mother and son. She offered them to sit down, and then she took a seat at her table. She smiled and said to Mrs. Henson, "You contacted us about a problem you were having. Please, tell me what appears to be the problem." She wanted Mrs. Henson to explain the problem first. "Err... My son and I live alone. I talk to him about all issues and I try to help him grow up. But now we need your help," she said with a faltering voice. "Of course, you can ask me anything, I'm here for you. You can relax, our conversation stays between us, Mrs. Henson. May I call you Kate?" Dr. Wood asked softly. "Yes, of course," Kate replied. "Okay, Kate. Please continue." "Well ... Erik and I are very close. We talk about everything and we help each other. Sometimes I try to talk to him about sex... I'm trying to substitute his father and teach him what his father would." "Yes, I understand, this is an important topic. I know it's difficult, filling in for his father. I agree that Erik's father could help but ... it's now your job. Is it a problem?" "Well, I think it is. When I try to talk to him about sex Erik just closes himself off. He doesn't want to talk about it at all." "Erik, is this true?" Dr. Wood now focused on Erik. He simply nodded in reply. "Come on Erik, speak up. Do you have a girlfriend?" she tried to change her approach. "No," he replied quietly. "Why, you are handsome young man. Are you possibly attracted to men?" Dr. Wood wanted to resolve the dilemma that Erik was gay immediately. "No, no," Erik responded quickly, but shortly again. "Well, are you attracted to girls?" He nodded and flushed. "Relax Erik, your mom and I are here to help you, aren't we, Kate?" it was her next test question for Kate. "Err ... yeah sure, mom will do anything to help you," Kate said to Erik. Dr Wood was smiling; she was satisfied with Kate's answer again. "So Erik, you need to be completely open in front of us in order to resolve your problem," Kate added encouragingly. "Yes mom, I will try," he said with more certainty. "Have you ever had a girlfriend?" Dr. Wood continued. "Yes, a year ago, but we dated only once," he finally answered longer and Dr. Wood was pleased. "Have you had sex with this girl or anyone else?" Erik opened his mouth to speak, but no sound came out and he just shook his head negatively. "Do you masturbate, Erik?" Dr. Wood asked softly. "Err... sometimes... but I felt dirty and guilty after I finished..." he hesitated but finally answered. "Oooh Erik, masturbating is really not a bad thing. You shouldn't feel guilty about it! Masturbation is normal for boys your age. Kate, you know that?" It was next test question for Kate. "Yes, I know. Could that be the problem?" Kate asked, confused and worried. "Yes, it could. Your son has to masturbate regularly. Masturbation helps increase his immune functioning, promotes healthy testosterone levels, improves blood flow to his genitals, increases muscle tone in his genitals." Dr. Wood paused and then asked Erik, "Do you have any problem with your genitals?" "No," he replied squirming and in a low tone. "That is fine, but I need to check your genitals," Dr. Wood said softly and turned to Kate, "You will stay with us, Kate, alright?" Dr. Wood asked Kate suggestively, again testing the mother's reaction. "Yes, I will," Kate answered a little too quickly and in a voice louder than necessary. She caught herself then quickly corrected her words, "I mean... if I can help." "Of course Kate, your help is necessary," confirmed Dr. Wood with a smile. She was pleased at how quickly Kate had accepted her offer. Dr. Wood stood up and said, "OK Erik, come over to the examination table." Erik did it obediently, went over to the table and laid on it. "Remove your pants, please," Dr. Wood said in a warm, reassuring voice. Erik paused, confused. "Right in front of my mom?" he thought. Dr. Wood noted that Erik was hesitating. "Don't be shy, I'm a doctor. And your mom has already seen you naked, right Kate?" she tried to relax Erik and tested Mom again. "Yes, yes ... Don't be shy Erik." Kate said and flushed slightly. Erik was a little confused why his mom would want to watch his examination. He had undone his belt and the top button of his jeans and lowered the zipper. Then he pulled down his jeans and underwear in one yank. He was exposed from the waist down, showing his private parts. Though limp, his cock was big and fat. His testicles at the base of his shaft were large and covered with fine but sparse hair. "Wow," Dr. Wood exclaimed excitedly, "I was afraid that Erik has a small penis and that it may be a problem. But he has developed very well," she spoke again to Kate. Kate's eyes grew wide and she froze. "Oh my God, he is HUGE!" she thought. Dr. Wood noted that Kate were staring on her son's cock and added in soft voice, "You should be proud of your son!" "Yes, thanks," Kate said shortly and blushed. She dared not look at the doctor. Dr. Wood looked up at Erik's blushing face as she reached forward, stroked his left thigh and said in a soothing voice, "Just relax, Erik. Now this may be a little embarrassing for you. I promise I'll be gentle." Then Erik felt her warm hands touch and lift his cock, squeezing it carefully along its length. "Do you have any pain when I touch your penis?" Dr. Wood asked, looking at Erik for a moment. "No," Erik replied huskily. "Great! Now Erik, keep your legs spread while I examine your testicles." Dr. Wood cupped his entire scrotum in her hand and gently squeezed his testicles. "Does my squeezing cause you any pain, Erik?" Dr. Wood asked again. "Just a little," Erik answered. Dr. Wood looked at Kate. She was breathing strongly and licking her lips as she stared in Erik's crotch. "Kate, don't worry. I feel no abnormalities with my finger. A little pain is normal, especially because Erik doesn't masturbate regularly." "Oh, I'm glad to hear it," Kate said with relief. Dr. Wood smiled and nodded encouragingly "Kate, you should be proud of your son again, because your big boy has impressive balls err... I mean testicles." This produced a stirring somewhere deep inside Kate. She was confused, but excited all the same. Then she asked Dr. Wood, "Is exam over?" "No darling, I have to check his foreskin. Maybe he has phimosis. Many men suffer from phimosis, which means that his foreskin is so tight that it can't be fully retracted over the head of the penis." Then Dr. Wood pulled back the foreskin of his penis for a moment, taking a look at the skin there, and then let it go back to normal. "Is it ok?" Kate asked worriedly. Now, she watched Erik's exam without hesitation. "There doesn't seem to be anything wrong. As we can see, the foreskin retracted easily. However, I have to check what the situation is when the penis is fully erect," Dr. Wood answered running her fingers very lightly all over Erik's shaft. "Erik, does that feel nice?" she asked. "Err...yes," he replied meekly. Erik couldn't believe what was happening. His cock was being fondled by Dr. Wood while his mom watched! Kate couldn't believe too what Dr. Wood was actually doing; that she was actually touching her son like that and that she wanted to give him an erection! Her breath caught in her throat as she watched Dr. Wood moving up and down Erik's cock until a large drop of clear liquid bubbled from the slit. Kate was embarrassed and turned her head away from her son's cock. Dr. Wood continued running her fingers and Erik's cock seemed to bulge in her hand in response. It didn't take her long before his penis was fully erect. Erik was ashamed at his sexual excitement, but loved the sensation of her hands rubbing his penis. "Excellent! Everything is ok, Kate. Look at, his foreskin can retract back behind the glans easily even in the erect penis," Dr. Wood did not hide her satisfaction. "Oh, thank goodness," Kate sighed with relief and then looked at Erik's cock again. Her head was spinning with excitement as her eyes were fixated on his penis. It was so huge that it made Dr. Wood's hand look small. "Oh, my God, it's so big," Kate moaned, unconsciously bringing her fingers to her mouth and sucking on them. It was truly the largest penis she had ever seen. "Yes, he has an incredible cock," Dr. Wood chuckled, winking at Kate. "Did Erik's father have a large penis, too?" "No, he had small and thin penis. I always had a problem with his," Kate said honestly. Realizing her boldness, her face flushed. "I understand, dear. A small penis can be a problem particularly if you have roomy vagina?" Dr. Wood said, a smile turning up the edges of her lips. "Yes, I do," Kate replied meekly. "So, it is meaning that you need a big and fat cock which can fill your roomy vagina. Don't you, Kate?" Dr. Wood did not stop rubbing Erik's cock while she asked. Kate nodded and flushed again, she just couldn't help herself. She was amazed at how her body was reacting to her son and this lovely woman! She felt her nipples begin to harden against her bra and her panties had become soaked when her pussy flooded. "Now, I'm sure Erik inherited genes from his mother. You and Erik both have rather exaggerated sexual characteristics. You have a meaty pussy and big tits and Erik has a huge penis and massive balls," Dr. Wood explained quite confidently. "Um...well yes, I agree," mumbled Kate. "Mom has a meaty pussy..." Erik repeated in his head with disbelief. "That can help us resolve Erik's problems," Dr. Wood noted. Kate nodded, trying not to be embarrassed, but still not succeeding. "Come on now, don't be shy Kate," Dr. Wood said encouragingly. "You must be able to help. There is nothing to be embarrassed about as we are dealing with helping to resolve Erik's condition for medical reasons. Would it be ok with you, Kate?" "Yes, I'll try to do it, since it's for medical reasons and to help my son," Kate replied. Then both women noticed that Erik was breathing heavily. "Any pain, now?" Dr. Wood asked again. "Err ... a little in the testicles," Erik said, now panting. A moan escaped from his lips. "As I said before it is normal Erik. You probably accumulated a lot of sperm in your testicles," Dr. Wood said and continued to pump her hands up and down rapidly. His glans was big and all wet from the precum that Dr. Wood skillfully used to lubricate and facilitate the jerking. Erik began to shake and it was clear that he was on the edge of an orgasm. He bit his lip and moaned softy in ecstasy. "He's going to cum," Kate whispered in an unheard warning to Dr. Wood. Dr. Wood nodded and accelerated her movement. A few moments later Erik exploded! Kate looked a little perturbed while she watched every hot blast of his cum ejaculating into the air. "Wonderful Erik," Dr. Wood cooed, glancing over at his mother. Her fists continued to move up and down, milking the juice from Erik's balls. She was very surprised by the amount of sperm that was flying all over the place, hitting Eric's stomach, the table, her blouse, her hand. "This big cock knows how to cum!" she said with sincere admiration. "He shot a massive load of cum, did he not Kate?" "Yes, yes..." Kate gasped. She stared in disbelief at Dr. Wood and her son. "Erik's amount of semen is well above normal, I think over 30 mL! The amount of average semen expelled in the ejaculation is approximately 10 to 15 mL. In addition, there were about 12 semen ejections with shooting ejections in the first half and dribbles in the second half. This number of semen ejections is considered high and well above average." Dr. Wood explained. Kate just nodded. Her eyes were wide with excitement and she was mesmerized by Erik's huge cumshot. "Kate, please hand me a towel," Dr. Wood interrupted her while still holding Erik's cock in her hand. Kate's knees were weak with excitement as she went for a towel. She handed Dr. Wood the towel who was wiped Erik and then himself slowly and carefully. "OK, Erik," Dr. Wood said finally, "Get you clothes back on and come back when you are ready." He dressed and joined the doctor and his mom a moment later. "Well, everything appears normal on the physical examination," Dr. Wood said, "Except that Erik is above average," she added with smile and looked at Kate. Kate blushed again. She realized that Dr. Wood has noted how Erik's huge cock fascinated her. "So, what is the problem?" Kate asked still worried. "I'm not sure yet. Erik, I need to talk with your mom in private." Dr. Wood paused for a moment, waiting. When Erik went out, Dr. Wood continued. "Firstly, I suggest that he get a regular emptying of his balls... err... testicles in order for him to ejaculate more efficiently and not get any nasty testicular conditions. We need to ensure that. Secondly, I think the problem for Erik in all of this was that he had been over-protected, and would be very controlling. That is why he is shy and insecure with women. That is why he has no self-confidence when it comes to women and dating." "It's my fault that he has no self-confidence," Kate blamed herself sadly. "Partially, but you can also do a lot to help him. Self-confidence, contrary to popular belief, isn't always bestowed at birth. It can be learned." Dr. Wood encouraged her. "What do you suggest for this then?" Kate asked. Apparently, she's interested in further conversation. "Erik believes you, and he will learn from you easier than from anyone else. Erik must masturbate regularly and frequently. Then he must become more relaxed and feel more comfortable with women. So Kate, in the first phase, I suggest you to masturbate your son." "But... What do you mean? Err... I can't!" Kate was completely confused. "Yes, you can! You told me earlier that you were ready to do anything to help him. Right, Kate?" Dr. Wood quoted her statement. "Yes, I said that, but I'm his mom!" "Not when you are masturbating him. During then, you're a woman and he's a man. Your man. I hope you will raise him to be a man." "But what will Erik say? What if someone finds out?" "Do not worry Kate. You can be sure that everything stays between us. Also, I will explain to Erik. I'm here to help you." "Well, I don't know ..." Kate was slowly changing her mind. "Relax Kate, this is nothing unusual, you will have my full support and assistance. In my practice, I have many such cases where the mother helped her son in various ways. It is important that you relax and enjoy. This will have a positive impact on Erik." "But, how can I relax...." "You have to accept that Erik is not a little boy and that he is a grown man. Do you agree that Erik grew up?" the doctor raised her eyebrows at Mrs. Henson. "Yes ..." "I want a full reply, Kate." "Yes, I agree that Erik has grown up." "Well done, Kate. And do you agree that Erik is a handsome young man?" "Yes, I agree that Erik is a handsome young man," Kate was now immediately giving a full answer and realized that saying it out loud changed her opinion of Erik. "Do you agree that Erik needs help with emptying his testicles?" "Yes, I agree that Erik needs help with emptying his testicles." "Do you agree that you will best help him to masturbate regularly and empty his testicles until they solve his problem?" "Yes, I agree that I shall best help him masturbate regularly and empty his testicles until they solve his problem." "Well done, Kate." "Thank you, Dr. Wood. I appreciate it so much for your support. I feel that I am ready to help Erik now. How often should Erik masturbate?" asked Kate, blushing with embarrassment. Dr. Wood was pleased. She expected to be able to convince Kate quickly, but she liked that Kate took the initiative. She did not want to give her an easy answer, "What do you think Kate, how many orgasms does a young stud like Erik need?" "Well, I do not know ... maybe 3-4 times a week," Kate tried to assess the needs of Erik. "Oh, Kate, that is definitely not enough! Remember how big Erik is and how much semen he produced? I suggest that you start with at least two times a day, once in the morning and once before he goes to bed. When you notice that Erik ejaculates a very small amount of sperm, then that's a sign that his discharge was enough for the day. " "Of course, you are right, Dr. Wood. Thank you. It's going to be a lot of work, isn't it?" "Well, yes, but Erik is young and inexperienced, and he will cum quickly. Also, if you want to speed things up, he will need some visual stimulation," added Dr. Wood with an enigmatic smile. "Visual stimulation? So... you think ... " Kate couldn't believe what the doctor said. "Yes, I think you can stimulate him by dressing up in some suitable lingerie and underwear which will help him to cum more quickly. You do have a lovely body, Kate." "Thank you," Kate blushed as she felt doctor's eyes roaming admiringly over her. "But not just that, Kate. He must see a woman in you, not just the mother. You need to watch his reaction. It's important to me to know how he reacts to women. Is that ok?" "OK, yes. I will try." "Thank you Kate, you're great. Not every woman or every mother could be so open-minded. Now, I'll invite Erik back in." When Erik came back in, Dr. Wood explained that he should not worry, that everything's all right with him. "Do you still feel the pain in your testicles, Erik?" "No, the pain is gone now," replied Erik, a little more relaxed. "Well, it's because we emptied your testicles. You're a healthy teenager, and your hormones are raging. We understand that. When the sperm accumulates in your testicles, then they begin to hurt. So, you need to ejaculate more often. Is that clear, Erik? " "Yes, Dr. Wood." "Since you don't have a girlfriend to help you, I asked your mom to help you in the same way as I did. Is that ok?" "Yes," Erik confirmed quickly. This pleasantly surprised Kate and the doctor since he did not protest. "Excellent," Dr. Wood said, now looking at Kate and smiling. "I suggest that your mom masturbate you twice a day, once in the morning and once before you go to bed. But don't be shy and ask her for help if you need it. Your mommy's here to take care of that for you, aren't you, Kate?" she continued. Erik's Transformation Ch. 01 "Yes, I am here to help you, honey," Kate confirmed, "Whenever you need to ejaculate, just ask me! OK baby?" "OK mom," Erik replied meekly. "Kate, today I was the one to empty Erik's balls. Do you want me to come assist you with the emptying tonight? I could do a home visit if you'd like," Dr. Wood obligingly offered her help. "Oh, definitely. That would mean a lot to me," Kate responded enthusiastically. "When should I come over?" "Maybe around 8 p.m. if that works for you," Kate suggested. "Okay, that sounds great," Dr. Wood confirmed. Then Dr Wood stood up, indicating that the consultation was over. Overall, she was very pleased. "Today is Thursday, so I will arrange an appointment to see you again next Monday. Then I will talk with Erik, but your observations are very important to me, Kate. Is that clear?" "Yes. Do not worry, Dr. Wood. I will try my best," Kate confidently affirmed. To be continued... Erik's Transformation Ch. 02 Many thanks to Nadia for editing and improving this. * Erik and his mother, Kate, arrived back at home after the appointment with Dr Taylor. Neither one could look at the other and soon it became quite awkward. It was about 11 a.m. and both of them were thinking about an upcoming doctor visit. Erik was totally unsure what to make of what just happened. He had come from the doctor's office where a sexy older woman jerked him off and let him cum and not only that but he did it in front of his mom! Then Dr. Wood prescribed "masturbation" as she had put it two times a day, and surprisingly enough, his mom was more than determined for the job! Although his mom was hot and he had been dreaming of her for years, he never thought that his mom was actually going to jerk him off! This was better than any fantasy he had ever had. Kate was also thinking about what had transpired in the doctor's office. She didn't know what had come over her when she agreed to jerk her own son off several times a day. She felt her own excitement increase as she thought about Erik and his big cock though. As the evening drew near, they both became nervous and excited. They were trying to hold a normal conversation. After dinner, Kate went to take a shower. She shaved her large, succulent pussy lips and after that, she thought of what to wear. She was looking for something sexy, as proposed by Dr. Wood. She found a bra that was transparent and revealed her large natural breasts. Her nipples were clearly outlined through the thin material. Then she found similar panties that were a size too small. When she got dressed those so small thin panties, it clung to the folds of her meaty pussy. After that, she put on black suspender belts that had a floral lace detailing, a soft mesh front panel, and a cute satin tab. Kate loved the feeling of stockings on her skin so she slipped on a pair of black fishnet stockings with a black seam and black satin ribbons. She felt feminine, seductive and kinky. Over that, she put on a short and tight dress that buttoned in the front, which pronounced her good figure and her round butt. She looked in the mirror and then undid the top and the last button on her dress. She was satisfied with her appearance as her short dress revealed the beginning of her cleavage and most of her shapely legs. Around 7:30 pm, Kate knocked on the door of Erik's room and reminded him that Dr. Wood was coming soon. Erik had taken a shower and fifteen minutes later he had gone down into the living room. He looked at his mom admiringly. Wow, he liked her new sexy look. The doorbell rang and Kate quickly got up and opened the door. Dr. Wood came in with a big smile on her face. "You look beautiful, Kate. And so sexy!" she said holding Kate's hand and looking at her from head to toe. She was pleasantly surprised by her transformation. "Am I right Erik?" she added with a wink. "Yes, my mom is very sexy," replied Erik as his answer surprised both of them. "Erik, do you feel the need for your mom empty your testicles?" Dr. Wood asked in a sultry voice. "Yes, I do," answered Erik without hesitation. "That's great! Kate, where do you propose you do it?" "Err...I suppose to do it in Erik's room or in my room." "Let's have a look," said Dr. Wood with another smile. They went into Erik's room first. "Hmmm, Erik's bed is a bit small. Let's take a look at your room, Kate." "Ooh, this is much better," exclaimed Dr. Wood, when she saw Kate had a king-sized bed. "It will be much more comfortable," she added. She wanted to begin their convergence in Kate's bed. Putting an arm around Kate's waist, she asked her eagerly, "Are you ready, darling?" "Yes, I think I am ready," responded Kate in a lust-filled voice. "Come on, Erik. Your mom is going to take your pants off." Erik come and stood in front of Kate with a bewildered expression. Slowly, Kate took Erik's t-shirt off. Dr. Wood noted that his chest was nicely developed and muscular. "Your son is grown man, is he?" She asked. "Yes," Kate agreed proudly and sank down to her knees, quickly undid her son's belt and pants, and slowly pulled them down to his feet. Then she tugged down Erik's underwear, freeing his very swollen cock, which immediately jumped up against his stomach. Her gasp joined that of Dr. Wood's. "Mmm Erik, I'm glad that you're relaxed and that your penis is ready," claimed Dr. Wood with smile. "Go on and take it, Kate," she ordered. Kate's heart was beating so hard that she thought it would explode. His cock was so fat she could barely get her fingers around it. Then slowly, she began to stroke it. "Oh it's so beautiful, isn't it Kate?" Dr. Wood mumbled as she admired the sight. "Yes, it's so beautiful and... so big," Kate replied, not hiding her amazement. Erik was in heaven. "Mom, that feels amazing," the moan escaped his lips. "Thank you, baby," replied Kate who was in ecstasy, too. Her tits shivered, her nipples was erect and hard. "Kate, I want you to empty Erik's testicles on your bed. There, he will be more comfortable," stated Dr. Wood. She grabbed Kate by the arm and helped her get up. Dr. Wood then placed Erik on the bed in a comfortable sitting position, putting a pillow under his back. Then, she positioned Kate on her knees between his legs. At the same time, she unbuttoned the top and bottom button on Kate's dress. Now her dress was buttoned with only the two middle buttons on her tummy. Kate did not protest. She agog leaned forward and took Erik's erect cock in her hand again, giving Erik a very nice view of her cleavage. There was much more than cleavage though and he could see the entire curve of the side of her large tit. He could also see the light pink skin surrounding her nipple. "Erik, do you like your mom's tits?" Dr. Wood asked him when she saw how he gazed upon his mother. "Err ... yes, yes... she is so hot," he said as his cheeks flushed red. Kate was now jerking off his cock with both hands. She was delighted with the size and thickness of his cock. She slowly lowered from the kneeling position to a sitting one with her legs tucked under her buttocks and her knees spread apart. Erik gasped because he could see his mom's crotch and the wet spot on her panties. The moisture also made her tight panties totally transparent and Kate's swollen pussy was clearly visible through the thin material. Dr. Wood even thought she could smell the arousal of Kate. Then Dr. Wood caught Erik's glance. "It's ok, sweetie, you can look at your sexy mother," Dr. Wood encouraged him as she sought confirmation from Kate. "Oh, yes... you can honey," replied Kate breathlessly. "Thank you, mom. I like looking at you," he admitted. Then, Dr. Wood unbuttoned the two remaining buttons on Kate's dress and moved the flaps of it to the side. Kate did not protest, again. Now the entire front side of her body was revealed and Eric could clearly see her heavy breasts in the transparent bra, her rounded naked belly, the sexy black suspender belts and her shaved swollen pussy in wet tight panties which produced the clearest camel toe possible. Kate felt his gaze burn her body. "Oh mom, you are so... beautiful and ... hot," Erik cried out. "Thanks honey, you too," Kate moaned. "I can tell that you like Erik's cock, Kate!" said Dr. Wood. "Err, yes, it's, uh, stunning," she stammered. "What about you, Erik? Do you feel good?" asked Dr. Wood "Yes..." nodded Erik as he gasped. "Does mom stroke your cock good?" "Yes, yes..." groaned Erik, biting his lip, letting his eyes close in pleasure. "Bravo Kate, keep it up!" Dr. Wood praised Kate's handiwork. "Look at you giving him what he needs!" "Oh yes," Kate whispered, her eyes wide. "That's what I need, too! Give me that beautiful cock!" Kate's hand went in full motion and she furiously jerked him off. Erik gasped as he felt his balls beginning to tighten and knew he couldn't hold back much longer. He started to whimper with each thrust and Dr. Wood yelled, "Go ahead Erik, give it to mom! Let her feel your hot cum!" "Oh cum to me, Erik. Give mom every drop," Kate whispered. She couldn't help feeling a stirring of lust deep in her pussy Soon enough, his orgasm released and he shot wildly in the air. The first shot went all over Kate's lips and chin. Kate aimed his cock in downward so the next few shots of cum went all over her bra and belly. Finally, it ended with just a few dribbles falling all over her panties. Kate was so covered in Erik's cum so he was sure she was going to yell at him for making such a mess. "I'm so sorry mom," he said, scared. "God, he gave her a cum bath," Dr. Wood thought. She looked in excitement at the mess Erik just made of his mother. "Wow Erik, your mom looks beautiful now! And don't be afraid. Mom likes your thick cum, right Kate?" "Yes, I like yours hot thick cum, honey," gasped Kate. She was amazed at the amount that came out. "Bravo Erik. You were good boy," Dr. Wood praised him. " Didn't you feel better now?" she asked. "Yes... yes, much better," confirmed Erik as he tried to catch his breath. "Good job, Kate!" The doctor beamed at Kate. "It was quick, as I told you?" "Yes, it was quick, and it was not hard for me at all," Kate answered honestly. "I hope you enjoyed it, too." "Oh yes, I enjoyed it very much. His cock was magnificent and... he came in amazing quantities," yelled Kate. "Yes, he had very voluminous ejaculations. I counted; he ejaculated eight long streams of semen. Remember, I warned you earlier how much semen he produced! This means that you should empty his balls as often as possible." "Yes, I will," said Kate enthusiastically. "I'm sure you can proceed now without me. I will see you both on Monday." Kate got up to follow the doctor. Cum poured down her body and she snatched the towel and quickly wiped herself off. Her legs were trembling as he closed the door behind the doctor. *** On Monday at 11 a.m. Kate and her son Erik went for a scheduled appointment with Dr. Wood. "Kate, Erik, how very good to see you again," she said beaming at both of them. "We are happy to see you too," Kate replied. Dr. Wood could see that Kate changed her outfit style. Her unbelievable body was encased in a tight business suit. She saw her curvy legs, her full, slightly swaying ass and her big, round breasts. "Kate, I have to notice you look very sexy." "Thank you," she replied shyly. When they sat on the sofa, the doctor looked at them questioningly and at Erik with a smile on his lips. "You both do look happy, does that mean that everything is ok?" They both nodded. Their smile spoke more than words. "Yes, everything is all right Dr. Wood," Erik added. Kate saw that he was now much more relaxed in dealing with Dr. Wood. "Kate, did you follow my advice that you should empty Erik's balls as often as possible?" Kate nodded and blushed a little. "Erik, do you feel better now?" asked the doctor. "Yes, much better," he answered with a faltering voice. "I do not feel any pain in the testicles anymore," he added as he relaxed further. "So how many times a day did you empty Erik's balls?" asked Dr. Wood with a smile. "Err... You suggested that we started with at least two times a day, so I masturbated Erik on Friday three times, than five times on Saturday, and yesterday err... six times, I think," Kate replied shyly. "Seven times, mom." Erik corrected Kate. "Hmmm .... yes, you are right honey, seven times," agreed Kate. "Bravo Kate!" enthusiastically commented Dr. Wood. "And bravo Erik, you're really potent and full of sexual energy. Obviously you were more and more relaxed day by day?" "Yes, I was more relaxed day by day and I enjoyed it more. So I felt the need to cum more and more," Erik said keenly. "Mmm, it's interesting. Tell me when did your mommy empty your balls for the first time?" "It was on Friday morning. Mom came into my room while I was sleeping. Mom's hand crawled into my pajamas and started caressing me. It was wonderful to wake up." "Ohh, his cock was hard before I even began to fondle him. He was so tense and he came in a couple of minutes so abundantly that my blouse was all soaked," added Kate. "Obviously, his balls were filled overnight. When did you jerk him off next?" "It was in the afternoon. When I came back from work, Erik was waiting for me in the living room with a bulge in his pants. I immediately knelt in front of him, took off his pants and gave him relief," Kate said coyly. "Did he cum large amounts of semen again?" Kate nodded and blushed. "Yes, I made a mess. Mom was showered in my cum. Her face, neck and blouse were covered with my sperm. But mom was not angry." "Erik, I told you that your mom likes your sperm and she likes you cum over her face and body. Kate, when did you empty his balls for the third time?" "I did it in his room before he went to bed." "Were you wearing something sexy?" Dr. Wood asked teasingly. "Yes, I was wearing a nightgown... " Kate said and paused searching for the right word. "Mom was so hot, her nightgown was transparent and she was not wearing a bra..." Erik explained. "Ohh, Kate, you're a really naughty girl! Erik do you like your mom naughty?" Dr. Wood asked provocatively. "Yes, I do. Because I cum harder and faster when she dresses like that." "Is this true?" Dr. Wood now asked Kate. "Yes, I feel it has really helped him. He came quickly and strongly. His sperm sprayed really far..." said Kate wanted to justify herself. "I' m glad it helped you. Very nice, Kate. But, how did you spend Saturday?" asked Dr. Wood. "I was preparing breakfast when Erik came into the kitchen. I saw a bulge in his pajamas, and I knew that he needed relief. He sat down at the table. I stroked his cock and soon a flurry of his sperm shot up in the air and all over my face and body. Again, that was an impressive amount of fluids he released and I had to change my clothes. After breakfast, I was cleaning out the living room and Erik helped me. After a few minutes, I noticed the bulge in his shorts." "It was quick wasn't it Erik?" "Yes... I watched my mom while we were working ... She was wearing tight short shorts and a tight white t-shirt braless. Her tits were swinging freely with every move. When she bent down, I could see her full round ass... It was so exciting to me." "Oh Erik, I understand you! Did your mom masturbate you in the living room?" "Yes. I lay down on the couch and mom masturbated me. I came quickly. My sperm shot up all over her t-shirt. After that, we continued to work. Mom did not change her t-shirt, which was wet with my sperm. Her nipples were clearly visible. I felt a hard on again and I said mom I needed relief. She gave me a naughty smile and immediately stroked my hard cock several times. Then she continued to work. Every couple of minutes she stopped to work and stroked my cock several times again. She was masturbating me up to the edge of orgasm, then stopped to cool things down. She obviously wanted this to last. Finally, we finished work and mom led me to my room so we would not have made a mess in the living room. I stood in the middle of the room and my mom knelt and took off my shorts. As soon as she started to stroke my cock I came so hard. I was ejaculating my jizz all over mom, again." "Oh poor Kate! Erik's thick sperm was all over you, again!" "Yes, I was soaked with his sperm and I had to change my clothing this time. Then I needed a little break... That was a lot for me... and I went to the shops. Do you understand me?" "Sure. You deserved it. It's not easy to restrain such a young stallion. Go on Kate." "When I came back from shopping, I went to the kitchen to prepare dinner," Kate continued. "Mmmm... yes, it was very nice. I could see mom's new sexy look when I went downstairs to the kitchen. She was wearing my old shirt that barely covered her ass. It was only a few buttons buttoned up. Mom was walking through the kitchen teasingly, she stretched and bent down," Erik tried describing the situation in the kitchen. "I enjoyed how Erik responded to my body so it was a pleasure for me to look sexy and provocative for him," added Kate. "I could see her tits swinging freely, her white panties, her fabulous ass, so I was soon hard as a rock. Then mom jerked me off and I came over her face and tits." Dr. Wood smiled again, giving them a clear sign that she was fully satisfied with what she heard. "Go ahead..." she added eagerly. "Fifth time I masturbated him before bedtime. This time I was wearing my new light pink pajamas," Kate started to explain. "Gee, mom looked awesome," Kate was interrupted by Erik. "Her pajamas were thin and so small. It just clung to her hot body..." "Kate, I suppose you're not wearing anything under the pajamas, no bra or panties?" asked Dr. Wood with a smile. "Err you're right... I wanted to be provocative," Kate answered and blushed. "Were you able to see her nipples through her small sexy pajamas, Erik?" "Yeah, mom's hard and dark nipples were clearly visible." "And?" "And I was able to see the shape of mom's ... err vulva." "Oooh Erik, you mean mom's pussy. You can say pussy or cunt. I suppose her pajamas was tiny and tight so clearly outlined her pussy lips. Mom has a meaty pussy, doesn't she?" "Yeah, mom has a beautiful meaty pussy. And I was able to see ... err ... a big wet spot on mom's crotch" "Oooh, that is normal Erik! Hard nipples and a wet spot on mom's crotch attest to mom's excitement. You should understand mom was enjoyed, too!" Erik nodded. He could not believe what the doctor just said. Talking with the doctor and mom like this was so exciting for him. "Kate, what amount of sperm did Erik produce this time?" "Slightly less than usual. But, I was covered in sperm, again." "It's very nice! I can not wait to hear how did you spend Sunday?" "He was still asleep when I went in his room. I removed the blanket and pulled his full erect cock out of his underwear. I pumped it slowly as I watched the head fill with blood with each stroke. It looked like it was going to explode and was dripping a steady stream of his juice. I knew his balls were full of sperm and he would soak my nightgown, again. That is why I decided ... err... how to say..." Kate obviously did not know how to explain. "Wow, it was amazing!" Erik took advantage of his mom's confusion. "I woke up immediately when mom took my cock in her hand. She stroked me slowly and then she bent her head, stuck out her tongue and licked my glans. It was incredible, feeling her warm wet tongue go up and down my cock. Then she took me into her warm mouth." "Wow Kate, you gave him a blow job!" Dr. Wood said it teasingly. "Yes, I did," she answered. "Did you let him cum in your mouth?" "Yes, I did," Kate said and blushed "Did you swallow?" "Yes, I tried, but I was not skilled enough that first time. A small stream of cum leaked from my mouth and tumbled from my lips over his cock." "Bravo Kate. You've found the best way to not make a mess and saved your nightgown. Did you like the taste of Erik's spunk?" "Oooh yes! It tasted so good, so thick and sweet." "Did you continue the blow job and emptying Erik's balls in the course of the day?" "Yes. In fact Erik seemed delighted with my mouth. After ten minutes he walked into the kitchen. He was only wearing a t-shirt. His cock was swaying as he walked. I saw that he was hard again. I blowed him and swallowed his cum, again. Then I told him to stay naked without underwear, because I wanted to see more easily when he is excited." "Great idea, Kate. Young stud was walking naked in the house. What about you? What were you wearing?" Erik's Transformation Ch. 02 "As I said, in the morning I was in a nightgown..." "Did you like this nightgown, Erik?" Dr. Wood wanted to include him in the conversation. "Yeah, it was a similar transparent nightgown like she wore yesterday. However, it was much shorter and I could clearly see my mom's long legs, thighs, rounded ass, black panties... And I could see her large full breasts through the thin material. They moved when she did." "Was she wearing her sexy nightgown all day?" "No, mom was wearing it until noon. Then, she asked me what I would like to see her wear." "Wow, mom was really a naughty girl! What did you say?" "I said that I would like she wear her black suspender belts, black fishnet stockings, black panties and bra. And high heel shoes." "Only that! Did you wear only that, Kate?" Kate nodded. "Wow Kate, you were almost naked." "Yes, I felt naked and exposed but liked the way he was looking at me with deep hunger and lust. And... I wanted to fulfill his wish," Kate said and blushed in embarrassment. "Ohh Kate, it was right. You've done the right thing. Now I understand why you must masturbate him seven times this day! Did you give him a blow job each time?" Kate nodded. "And did you swallow each time?" Kate nodded again. "Bravo Kate. You were so hungry on Sunday! I hope Erik has richly fed you." Dr. Wood chuckled, winking at Erik. Than she continued, "Erik, may I talk with your mom alone?" "Yes," answered Erik and he stood up obediently. Dr. Wood noticed the huge bulge in Erik's slacks...a sizable bulge! "Poor boy. You already have a big erection! You must be in more need than I thought. Kate you must help him." Kate got up unquestioningly and came over to him. "You should give to him a little visual stimulation. He's used to it," Dr. Wood reminded her. After some initial hesitation, Kate took off her jacket and then the blouse. Her pretty little bra could barely hold her big tits and the cups hardly even covered half of those big melons. "It's not like your bra is hiding anything. It's so small on your body that Erik can see everything you've got. So if you took off your bra he wouldn't see any more of your tits than he can already see right now. And you'd be more comfortable." Dr. Wood was suggested. Kate hesitated a bit and said, "That's true." Then Dr. Wood approached Kate from the back and removed her bra, completely exposing her large heavy tits with their dark and very hard nipples. Then she took her right breast and started to play with her nipple, rolling it between her fingers. "Oh, oh ... yes!" Kate called out. "Mom has beautiful tits, doesn't she Erik?" Erik nodded mutely, unable to believe what he was hearing and watching. His eyes lingered on his mom's breasts watching them swell with Kate's breathing. "I think Erik deserves an extra stimulation. So, come here and play with yours mom's beautiful tits," Dr Wood said. Erik approached Kate and he was grabbing her tits. Both of them gasped. For the first time, he could feel the softness and the weight of his mom's tits. "Wow," Erik gasped. "You have such amazing tits mom." "Thank you, baby," Kate gasped. After a few minutes Dr. Wood said softly, "That's enough, Erik. Let your mom satisfy you." Kate knelt and with an unhidden expression of pleasure on her face, she unzipped his pants and pulled them down. Then she took off his underwear. His big swollen cock jumped in the air. She grabbed his cock and held it in front of her face. "Oh, how I like that!" she whispered. "I know that," said Dr. Wood encouraging and supporting her, "relax and go ahead, Kate." Kate rubbed his cock alongside her face which left a sticky mess on her cheek. Then, she rubbed it along the other side of her face which caused Erik's hips to jerk when she flicked her tongue across the swollen tip of his cock. Kate swirled her tongue around the head for a moment before starting to bob her head. Then she opened her mouth wider and slid her full lips along the length of his cock. "Oh yes!" he moaned as she started bobbing her head up and down. Smiling at Erik, Dr. Wood said, "How does mom look sucking your cock Erik?" "Amazing," he said softly. "Yeah, your nice big cock looks good in your mom's mouth!" smiled Dr. Wood, "You're a lucky boy." Kate kept up the pace of slamming her mouth and throat down on Erik's cock, each time hitting the root of his cock and pressing her face into his groin. She was moaning the entire time and she could already feel his thighs shaking. "Oh, yes," he moaned, "Oh mom, that feels so good, I..." he gasped. "Kate, please do not swallow. I want to see amount that he shot," Dr. Wood demanded. Kate confirmed, mumbling and tightened her mouth around his cock. "Ah mom, I'm cuuummiing," Erik cried as his cock exploded deep into his mom's mouth. Kate moaned loudly and started sucking him hard and fast. Her cheeks hollowed out as she started sucking so hard he could feel her pulling the cum from his still shooting cock. Finally, she pulled his cock from her mouth and opened it widely. Her mouth was full with white thick cum! "Oh my. That was an impressive amount of fluids he just released. Bravo Erik! Do you want to swallow it, Kate?" she asked her teasingly. Kate just nodded, her mouth was still open. "Ok, swallow it you naughty girl," she said with understanding. Kate closed her mouth and swallowed hard. As she did her eyes rolled back in her head and she moaned softly. Then she opened her mouth again, showing Dr. Wood it was empty. She sighed and shaking her head exclaimed, "God I love the taste of Erik's cum!" "I know! Erik, may I talk with your mom alone after all?" Erik nodded. He pulled his pants back on and walked out of the office. "Congratulations, Kate! I am very pleased with the results of your learning session. Thanks to you Erik progressed a lot in just a few days. His self-confidence has increased. He is not as shy as he was and I was pleasantly surprised how he responded to my questions today. He has learned a lot and you're an excellent teacher." "Thank you. I gave my best." "I believe you. The result confirms that. Well, tell me how he reacted to you as a female." "As you suggested I dressed provocatively. In the beginning, he was embarrassed and he was glancing at me briefly and warily. I tried not look at him when he looked at me. I also told him that he might freely watch me. It helped and soon he was looking at me without shame. He even started giving me compliments and commented how he likes my body, how I am beautiful... I feel so much closer to him now than I ever have been." "Great Kate. Things are going better than I expected. I think he's ready for the next phase." "What is the next phase?" asked Kate, a little confused. "By now, we recognized his problem. Erik inherited genes from you. He has exaggerated sexual characteristics and high libido. But Erik was feeling insecure around sex and females. We have found a solution - he believes you and he needs your help to reveal the magic of sex. So the next phase is that he has sex." Dr. Wood paused for a short while. "Kate, I plan to let him fuck you!" "What... I can't do that." "Yes, you can. Remember Kate, your help is the key to his success." "I know... but..." "Just relax and I am sure you will enjoy it, Kate. You need sex, too. I know how your body was reacting to your son. Erik knows too. He noticed how your crotch was wet with excitement." Kate nodded and flushed. "Kate, I don't want to rush you. You think over this and call me when you decide." To be continued Erik's Transformation Ch. 03 Many thanks to Nadia for editing and improving this. * As they drove home, Kate was confused and thought about the proposal from Dr. Wood. Her voice echoed in her mind, "Kate, I plan to let him fuck you!" She was a bit shocked, but at the same time she was very excited by that statement. She was wondering if it was the right way to help Erik. Should she obey Dr. Wood? Dr. Wood was someone whom Kate believed in and respected. Erik's question interrupted her thinking. "Mom, are you going to work today?" "No, I took the day off." "Excellent! We'll have the whole day just for us." He was very cheerful and happy and Kate had to admit that Dr. Wood was right and that her therapy was evidently working well. When they arrived home, Erik began to undress immediately and without any shame. His semi-erect cock jumped out of his underwear. "Oh horny boy, you need relief, don't you?" Kate asked provocatively. "Yes mom, I do," he answered proudly. He did not hide that he enjoyed the sex games with his mom. She came over to him and took off his T-shirt. Now Erik was completely naked. She kissed him gently on the cheek. Her hands caressed his face, neck, shoulders and chest. She enjoyed the firmness of his body while she realized that this was a real man in front of her. "Mom, can I see your tits again?" Kate paused for a second. She was a little surprised with his immediate question. "Of course honey," she replied meekly. He did not wait for her and started unbuttoning her blouse. Soon it fell open, revealing a thin and sexy bra. "Wow mom, you are so hot," Erik exclaimed. "Can I touch them, mom?" asked Erik pleadingly. "Yes," she gasped and blushed. "It's something we've already done for the doctor," she thought. He took her breasts out of her bra and squeezed them some more. Kate moaned with pleasure and opened her eyes wide but she didn't move. Erik realized that she surrendered and without questions he took one of her breasts into his mouth. Her body trembled spontaneously and her moans increased as he sucked on one oversensitive nipple and played with the other. Her hands instinctively grasped his head, bringing him deeper into the swell of her breast. She was horny and the lack of sex had left her utterly frustrated. "Oh, I'm not going to be able to stop him..." she thought. Finally, Kate gathered her strength and finally spoke up. "Please, honey... that's enough. Let me satisfy your needs." Then, she lowered herself to her knees in front of him and there was a very thick, long, hard cock, ready for action. She was shocked to find her pussy drooling heavily and pulsing in her panties as she thought about how it would feel to have Erik thrusting his big hard cock into her meaty pussy, satisfying her wanton needs. Now she was sure that she also needed a good, hard, long fuck. She put her hands on his hips and opened her mouth in the shape of an "O" as wide as she could. Without moving her head, she lightly pulled his ass forward. The hugely swollen head of her son's prick penetrated her warm mouth. Erik groaned out his pleasure when he felt his cock-head slide into his mom's hot, wet, and silky smooth mouth. Then, she pushed his hips and his cock-head plopped out of her mouth. Quickly, she pulled his hips forward again and now his cock penetrated her mouth a bit deeper. She continued to rhythmically push forward and back on his hips and gradually she let his giant, throbbing cock penetrate her mouth inch after inch. Reflexively, he began to wiggle his hips back and forth in her mouth each time deeper and deeper. Erik looked down at her and he saw her cheeks were expanding outward from his fat cock thrusting in and out. He groaned when he realized that he was actually fucking the mouth of his beautiful, horny mom. She moaned low and lustily and relaxed her throat to receive his big cock as deep as possible. "Ohhhhh, yessss!" Erik groaned as he thrust his cock deep in his mom's throat. He could feel her throat stretch to accommodate the swelling of the head of his cock. Kate moved her tongue down to flick gently over his balls while her throat tightened and loosened around him. He thrust deep again and again. Finally, Kate felt him exploding in her mouth and he shot a big load of his hot, slick semen down the back of her mouth and into her throat. His orgasm was so intense, his knees got weak and he had to hold on to her head. "Ooohhh...mmmm..." Kate moaned loudly as her control loosened. She moaned in ecstasy, her mouth was overflowing with Erik's hot thick sperm and she hungrily tried to swallow all of it. Erik continued to fuck her mouth gently until his hard-on went soft in her mouth. "Oh, mom, that was great!" Erik sighed. "Can we do this again later...please?" Kate finally let go of his cock and stood up. After his furious mouth-fucking, her whole body was absolutely glowing with lust. She was breathing heavily and her head was spinning. One thought formed in Kate's dazed mind, "fuck that beautiful cock as soon as possible." "Mom, can we do this again..." he repeated pleadingly. "That was soooo good!" "Would you like that?" she asked, her voice husky with arousal. "Yes mom, it felt so incredibly good." "Ok, we can do that again, honey! And more..." She kissed him gently on the cheek. Then, she took her blouse and bra and went to his room. Erik enjoyed seeing her naked, heavy breasts which swayed as she walked. ** Kate was sure she could not wait any more. She called her boss and told him that she need some days off. Then, she called Dr. Wood. "Hi, Kate speaking." Kate said uncertainly. "Ooh Kate, how are you?" Dr. Wood was surprised. She didn't expect that Kate would call so soon. "Err, I am fine. I thought ... about your proposal, and..." "Did you make a decision, darling?" Dr. Wood asked softly. "Yes, I think ... I have to help him. I wish that his self-confidence increases." She said to cover up her own needs. "Of course Kate, are you ready to let him fuck you?" Dr. Wood asked directly. "Yes, I am ready," Kate replied meekly. "Bravo Kate!" She was pleasantly surprised by Kate's quick decision. Now, she was absolutely sure that Kate needed a good fuck and a big cock badly. "But... err... can you assist me ... you know ... the first time?" "Of course, Kate! I am here to help you. Now it is 2 p.m. I'll be there in an hour because I want to have all afternoon for us and I want to have enough time for your first fucking. I want to teach Erik slowly how to fuck you." "Yes, yes..." Although she was not expecting that the doctor would come so soon, Kate agreed without protest. They ended the conversation and Kate went to take a shower. Then, she put on only small panties and a short bathrobe without a bra. The crotch of her thin panties was not quite wide enough to cover all of her femininity, which looked incredible. Her bathrobe was so short that it barely covered her round ass and her fully shaped thighs were completely exposed. The deep neckline revealed most of her large breasts. Kate realized that she now enjoyed wearing sexy clothes and flaunting her outrageous femininity and sensuality. When she walked into the living room, Erik was sitting naked and watching TV. He saw her and cried out, "Wow mom, you are ... so sexy". "Thanks honey," she smiled. "Please, put on your underwear. Dr. Wood will be arriving soon." "Why is she coming?" he asked worriedly. "Do not worry. She wants to talk about your further progress," she said soothingly. Soon enough, the doorbell rang and Kate opened the door. "Wow, my darling. You are so cute and sexy," Dr. Wood did not hide her excitement to see Kate in this release. They sat in the living room and Erik brought them a drink. His erection was huge and he was not trying to hide it. "Obviously your cock likes mom's sexy look," Dr. Wood joked with him. "Yeah," Erik answered shortly and blushed. "Kate, did you empty his testicles since you came home from my office?" "Yes, of course. He needed relief as soon as we got home." "Ooh, bravo Erik! How did you satisfy him, Kate? "Well he asked to see my tits and I let him..." "Yes, I saw that he liked your big tits. Did you let him touch and squeeze them?" "Err, yes..." "And mom let me kiss her tits and suck her nipples," added Erik proudly. "Really? Bravo Kate. How did it feel when Erik kissed your nipples?" Dr. Wood asked. "Mmmm, marvelous!" Kate exclaimed honestly and blushed. "Erik, you have to know that your mom has very sensitive nipples and you must be very gentle when you start sucking them. In this manner, mom will really enjoy your sucking." Erik nodded when he realized that Dr. Wood suggested him to suck his mom's nipples again! "Did she give you a blowjob?" "Actually, she let me fuck her mouth," Erik replied honestly. "Wow, excellent Kate! Tell me more, Erik." "Well, mom knelt in front of me and did not move her head. She put her hands on my hips and pulled forward and back...Then I started to fuck her mouth, it was so soft and warm! My dick slid along her tongue and was hitting on her cheeks. Mom made "mmmm" sounds and I was overwhelmingly excited by the sight of my wet cock head fucking mom's mouth. I rammed my dick deeper and deeper and then I felt the cock head penetrate her throat! I did it again and again ... Wow, it was amazing and I had to cum!" "You're a lucky guy, Erik! Most guys never get to experience deep throat, because most women cannot suppress a gag reflex. But your mom is a skilled woman," Dr. Wood smiled at Kate who blushed again. Erik was proud of his mother. He remembered when she first time sucked his cock and that it was strange for him that she did not respond when his cock penetrated her throat. "How did he cum, Kate?" asked Dr. Wood. "Err, he came hard and abundantly. His cock-head was deep in my throat and his first two spurts of semen went straight into my esophagus. Then he move back his cock and his next two spurts filled my mouth. When he pulled out his cock, he gave me two more bursts of sperm on my cheeks and lips," she replied and unknowingly licked her lips. "Wow, mom was covered in sperm again," cooed Dr. Wood, glancing at Kate. "Yes, it was an amazing sight!" Erik confirmed happily. "Do you like mom making you cum in her mouth?" "Yes, I do. I really do," he answered enthusiastically. "That's because your mom has an attitude where she is content and looking forward to having a fun sexual time with you. And you were able to sense it. Her attitude plays a role that is far more important than any technique mom can use on you. That's why I want you to learn more about sex from your mom." Erik nodded but he still did not understand what the doctor wanted. Dr. Wood continued, "Your mother and I think you're ready for the next stage of learning. Erik, I think it's time to make love to your mother." "Wow, you think ... fuck..." "Yes, I think it's time to fuck your curvaceous mom. Would you like fuck your mom, Erik?" "Yes, yes ... of course ... a lot. But... mom... does she..." "Do not worry. Mama really wants it too, right Kate?" "Yes, mom really wants you to fuck me, honey," Kate replied meekly. "Wow mom, I cannot wait..." Erik did not hide his verve. "Oh, your cock is so nice! You are so hard for your mom, aren't you?" Dr. Wood asked and stroked her hand over his large bulge. Erik moaned as she gave his cock a hard squeeze and just nodded. "Erik, now we are going to play sexy games for adults. So, do not be shy. Mom and I will help you. Kate, I recommend that we go to your bedroom," Dr. Wood whispered and stood up. Without delay, they followed after her. When they entered her room, Dr. Wood asked, "Have you kissed him before, Kate?" "Err ... no... we have not kissed yet," Kate responded. "Erik must learn that romantic love is different from maternal love. It's an intense, new feeling unlike any of those other ways of loving. Our ability to feel romantic love develops during adolescence, in Erik's age. It's a natural part of growing up to develop romantic feelings and sexual attractions to others. These new feelings can be so exciting. Kissing will help Erik become more relaxed. It's important that he has a feeling of emotional closeness with you, Kate. Do you understand?" asked Dr. Wood. Both of them nodded. "Now Erik, kiss your mom, lick and suck her lips. Kate show him," added Dr. Wood. Kate felt breathless as Erik pulled her closer to him. She seized his face with both hands and pulled him toward her so that she could test out her beautiful lips. Kate lightly grazed her lips over his, keeping the pressure as soft as possible. After she did that a few times, she shifted her focus to gently kissing his lower lip. Then, she opened her mouth to him, probing with the tip of her tongue. Mother and son began exploring and tasting each others mouths. Both of them couldn't fight the moan of delectation. Kissing her son was turning Kate on even more. "Great Kate, you are an excellent teacher. Do you like kissing your mom, Erik?" Finally, Kate parted from her son and Erik answered breathlessly. "I like kissing mom. It was hot and exciting. Her lips are so soft and wet and I love to play with her wet tongue." "Nice, now let's fuck your mother," said Dr. Wood. "Undress you and your mom, Erik." Erik took off his T-shirt and underwear quickly, freeing his hard cock. Then, he took off his mom's bathrobe and exposed her breasts and hard nipples. He squeezed her naked breast spontaneously and Kate moaned. "Kate, for the first time I suggest that Erik penetrates you from behind." "You think he should fuck me in ... doggy position?" asked Kate who blushed. "Yes, Kate. Please get on all fours. I want your ass in the air." Kate got on her knees and elbows and Erik and Dr. Wood were able to see her round ass, her vaginal length and even the plumpness of her lips. Her small panties were wet and transparent. Kate felt a new excitement in this position and she was aware that she was exposed to them completely. "Wow, look at this Erik! Yours mom's bottom is solid and wide in construction. Her curvy thighs are sturdy. It's good for you that your mom is so well-constructed. In addition, your mom is always extremely wet. All of that ensures that she can withstand your big cock and your hard fucking." Erik liked to listen to her explanations and tried to be careful. Then, Dr. Wood took off Kate's panties and now she was completely naked. "Oh mom, you are so wet," Erik exclaimed in amazement. Kate was very excited and she could not stem the juices running down the insides of her legs. Dr. Wood was also amazed at how Kate was wet and how swollen her big vaginal lips were. "Come on, Erik. Mom cannot wait any more!" The doctor wrapped her hands around his cock and led him to mom's butt. Several times she slapped her ass with his cock. Then, she put his cock head on her vulva and spread the lips slightly. She stroked her pussy gently and let his cock hit her clitoris ever so lightly. Dr. Wood noticed a slight jerk of Kate's hips along with a sharp gasp. She smelt intensively like a bitch in heat, her vaginal lips were wide open and the doctor knew Kate was more than ready to receive his cock. Clutching his cock she put his glans at the entrance of her pussy. Kate moaned, lowered her head to the pillow and pushed her well-shaped ass up beggingly at Erik. "Your pussy is very sensitive, isn't it?" Dr. Wood asked. "Ohh... yes!" Kate agreed. "Erik, you are huge, be careful and enter your mom slowly." Erik pushed his hips forward and the doctor let him penetrate Kate only one inch. "Ahh... ahhhh," Kate moaned. She had never been stretched like that until now. "Are you okay, Kate?" Dr. Wood asked worriedly while she caressed her back. "Yes ...ahh it's so good!" The doctor moved her hand on Erik's cock and let him penetrate her pussy another inch deeper. "Ohh mom, your pussy is so hot and tight!" Erik said enthusiastically and started sliding his hips back and forth, thrusting his cock deeper and deeper into her amazing pussy. "Ohh yes..." Kate could not stop moaning. "Kate, more than half of his cock is in you. Do you want more?" Dr. Wood asked. "Ohh... yes I want... I need .." Kate replied pleadingly. Dr. Wood removed her hand from Erik's cock and he impaled her completely in one wet stroke. "Slowly Erik, fuck your mom slowly! Relax and enjoy it, Kate. Let your little boy fuck you deeply." Erik almost withdrew completely and then slowly slid it in all the way again. "Ohhhh, good, Erik ... damn good. Oh, I couldn't wait to get all of your cock inside me," Kate sighed. She was ecstatic and kept saying, "Yes honey ... deep and slowly, ahh... deep and slowly. I like that, Erik." Her pendulous heavy breasts were swaying in rhythm with his fucking and Dr. Wood could not resist and gently tightened Kate's breast and nipple. Kate moaned more loudly. She had never felt so full in her entire life. She had never been penetrated so deeply before. She felt the head of his cock slamming against her cervix and this was a new feeling for her. Kate knew the oncoming orgasm was going to be huge. "Ahh... Ahh... Ahhhh!" she practically melted with pleasure from the Erik's fuck. "Bravo Erik, your mom orgasmed so strongly. Continue to fuck her. She needs more. Swivel your hips in a circle so mom can feel your cock from all angles." Erik did as he was told and he felt his mother's cunt squeezing and pulsating. "Mom ... ohh . I am going to come..." "Don't worry about it, Erik. This is your first time. Cum as soon as you can. Cum for your mommy," Dr. Wood encouraged him. Erik groaned as he thrust his cock deep into his mom's pussy. The sperm spouted from the end of his massive cock and Kate felt his hot semen fill her pussy and womb. It was so exciting and she squealed and grunted as a second orgasm took her. "Honey, oh God... ohhh I'm cumming, honey, ohhhh...you made me cum again..." Dr. Wood was pleased to see that Kate thrust her ass against his spurting cock, unable to resist. Erik continued to thrust in and out, fucking mom's glorious cunt. Finally, he became too weary to maintain the movement and he stood, unmoving and with his cock still buried in his mom's pussy. "Erik, you've been great. You filled mom's pussy with your sperm. Come out slowly now." Kate moaned in disappointment when he pulled his dick out of her pussy. Erik sat next to mom, stroking her back and gasping for air. Kate did not move and gasped for air too. Her round firm ass was in the air and Dr. Wood noticed she still had her pussy wide open. "Look at your mom's beautiful pussy and how it's very wet and swollen. Your fat cock made mom's pussy gape wide open." Dr. Wood put her hand on Kate's ass and Kate felt the doctor's finger slip between her full pussy lips. Kate let out a loud moan and then covered her mouth. "It's okay, Kate. Do not be shy and do not restrain yourself. I understand that it's hard for you to resist his beautiful cock. Lie down now on your back and rest, you've earned it. So, did you enjoy this experience, Erik?" Dr. Wood now focused on Erik, but she did not stop caressing Kate's tummy and pussy. "Oh, yes, that was, that was... ahh ... the greatest thing I ever felt," he answered, still slightly out of breath. "I'm glad to hear that from you!" Dr. Wood did not hide her pleasure. "It is important that you enjoy sex, but do not forget that it is important that your partner enjoys it too. You have to know what your partner likes and you have to be careful with your partner, as you have been careful with your mother a little while ago. You've noticed how your mom enjoyed it all?" Erik's Transformation Ch. 03 Erik nodded. "Yes, you were attentive and mom enjoyed it greatly. Although you fucked her just ten minutes, your mom orgasmed twice! Your mom is a woman who loves a thick cock. A cock's circumference is very important to your mom. Remember mom's sensitive genital tissues are located around the perimeter of her vagina. Mom's G-spot is located within a couple inches of the vaginal orifice. The more pressure that is exerted on these structures, the more enjoyable intercourse will be for your mom. That's why your mom enjoyed it when you spread her pussy with your thick cock. "On the other hand, pounding on a woman's cervix may be very pleasant for her and can be enjoyable for some women, like your mom. This area gets more sensitive as an orgasm approaches. You've noticed how your mom loved when you rubbed her cervix with your cock-head and how then she orgasmed strongly. For that reason, when you fuck a woman like your mom, always penetrate deep into her pussy and gently rub her cervix." Erik nodded again. Dr. Wood noticed that his cock was fully erect again. Obviously, her advice had been exciting for him. She moved her hand from Kate's belly to her slippery pussy and Kate moaned. "We talked for a long time. I can tell that mom is very aroused. Mom's pussy is hungry and mom can't wait any longer. She needs a new portion of sperm. Now, you're going to fuck your mom in missionary position. Please Kate, make sure you feel comfortable in the bed and spread your legs wide for Erik." Kate blushed but she did it with enthusiasm as the doctor said. Her legs were spread wide and her meaty pussy was completely exposed. A small stream of cum poured out from her pussy and Erik exclaimed, "Ohhh mom, your pussy is so beautiful! I need to fuck your pussy again and again." "Yes, honey, mom needs your beautiful cock... ahh ... fuck me, please," Kate moaned keenly. To be continued... Erik's Transformation Ch. 04 Many thanks to Zat7, Jack and Gary_starspear for editing and improving this. * "I want you, Erik... inside of me. Now... please ... fuck me honey!" Kate moaned in misery again. She moved her pelvis up and down, seductively teasing him. It was obvious that she could not hide her lust in front of Eric and Dr. Wood. She wiggled and pleaded with Erik to enter her, beyond caring how wanton she might sound. She was a sultry temptress, and she reveled in that sinful persona. Dr. Wood chuckled. "Not just yet, darling. Do not worry, be patient and Erik will fuck you soon. Your cunt is filled with his sperm. His cum is oozing from your pussy and I want to clean it for him. At the same time I want to teach Erik how to lick your pussy." "Wow yes, I want to learn how to lick mom's pussy!" Erik did not hide his verve. Kate was shocked; she was never with a woman. "I've never done that...ummm...with a woman before," Kate gasped. Dr. Wood smiled knowingly. "Does it matter, Kate? Just relax and enjoy it!" The thought that Dr. Wood was going to lick her in the presence of Erik brought heightened excitement to Kate. She just groaned helplessly giving a sign that she accepted it all. Dr. Wood moved so that she settled between Kate's thighs. Erik sat down at the right side of his mom and watched curiously. Then Dr. Wood's hand went to Kate's pussy, and she found that her smooth pussy lips were puffed up with arousal and sopping wet. "Erik, look at your mom's pussy lips. Feel how big and meaty they have gotten now that she is enormously turned on. Rub them with your hand," Dr. Wood was giving him instructions on how to fondle his mom and how to give her pleasure. Kate moaned when she felt Erik's fingers on her oversensitive pussy lips. "Ohh... that feels ... so good honey," Kate confirmed how much she enjoy their caress. Dr. Wood moved Erik's hand to her clit, and he found it erect and instinctively begging to be played with. Kate moaned again, completely surrendering. "Just gently Erik, mom's clit is very sensitive," the doctor continued to give him instructions. Kate's body was shaking with pleasure and after a few minutes, the doctor added, " That's enough, Erik." Erik obediently removed his hand from mom's pussy. Dr. Wood approached her face to Kate's pussy and Erik could hear the doctor deeply inhaling his mom's pussy. "Mmmm, your mom's pussy smells wonderful." Dr. Wood said looking from Kate's cunt to Erik's face before looking back at Kate's cunt again. Then Dr. Wood lowered her face into Kate's crotch and began to lick and suck her pussy. She slowly pushed her tongue deeper into Kate's slick hole, swirling the tip from side-to-side, and up and down. She hungrily was eating his cum out of mom's pussy. She licked up to her clitoris, circling it and then back down into her slit. Kate's eyes were closed, her mouth open, as gasps and whines escaped, indicating her pleasure. "God, mom's juices and your cum taste so good!" Dr. Wood said enthusiastically. Erik watched in amazement how the doctor was licking up the cum leaking out of his mom's pussy. "Now it's your turn, Erik!" Dr. Wood said and stood up, offering her place to Erik. Erik lowered his head between his mom's thighs, resting his nose against her vulva. His eyes were glued to her womanhood and wetness. Mom's swollen pussy was so beautiful. It was the most amazing, most beautiful thing he had ever seen. "Smell your mom's pussy" Dr. Wood encouraged him. Erik inhaled deeply. "Mmmm, damn mom, your pussy smells so good! I like this scent," he said honestly. "Yes Erik. Mom's pussy has a sweet smell, but remember, every woman has a slightly different scent - some light, some strong, some musky, some sweet. A woman's vagina is actually very clean inside due to the body's own natural mechanisms. I especially like your mom's regular natural smell. It's the smell of a healthy woman who is very excited. Your mom smells intensively like a bitch in heat. This smell is a woman's way of sending signals that she is ready for mating. Remember that, Erik." Erik nodded, confirming that he understood. "Now, stick out your tongue and lick mommy's pussy lips. Your tongue should be spread," the doctor continued to give him instructions. Erik pushed his face and licked mom's pussy. Kate groaned with pleasure. "Well done, Erik! Now, taper your tongue and fuck your mom with it," added Dr. Wood. Erik pushed his face deeper into Kate's wetness, separating her cunt lips with his mouth as he fucked her pussy with his tapered tongue. Kate's juices were flowing, mixed with his saliva, coating his chin, lips, and cheeks. Kate was continuously writhing and moaning as Erik licked and ate her pussy with passion! At the same time, Dr. Wood was running her right hand up and down Kate's belly, cupping and squeezing her large tits. Then Erik's tongue teased her clitoris. She completely lost track of where she was. All of that sent Kate over the edge. She arched her back and thrust her pelvis up into Erik face, and at the same time, she pressed his face deep into her crotch as he licked and sucked her clitoris. "Ohh ... honey ... I'm cumming..." Kate screamed in disbelief as her orgasm swept over her. "There's nothing to be afraid of Kate. Just relax, enjoy it and give yourself to him," Dr. Wood encouraged her. "Yes, I will... try... I'm a more relaxed now," Kate said, breathing heavily. "I am glad to hear that, Kate." Dr. Wood said and continued running her hand up and down Kate's belly and tits. "And ... I really enjoy it doctor..." Kate added innocently. "Mmm lovely. You are a highly libidinous woman and it is quite normal for a woman like you to enjoy sex. In addition, evidently Erik learns very quickly. Congratulations Erik! You made mom cum on your tongue. Now, lie down over your hot mommy," the doctor gave him new instructions. He did as the doctor said. Kate moaned when she felt his weight on her and immediately wrapped her legs around his waist. She felt the hard length of his cock fall upon her swollen pussy lips. She wiggled her hips just a bit, to bring it closer. "Kiss mommy, Erik. Caress her voluptuous body and tits. Tease her with your touch," Dr. Wood continued. Erik looked at his mom's eyes and slowly leaned in to kiss her. When their lips met, Kate could taste her pussy on his lips. His tongue slid into her mouth and he drove his tongue as deep as he could get it and listened to mom's moans as he kissed her. "I love you mom, so much," he said passionately. "I love you too, my big boy!" Kate answered gaspingly as she writhed beneath him. Erik reached up, captured each of her heaving breasts, squeezed, and pinched her swollen nipples with his fingers. "Suck her nipples, Erik. Mom likes it!" Dr. Wood continued. Kate's nipples were taut, aching out to be teased and tasted. His tongue swirled around one nipple, then the other. She enjoyed the feeling of his warm lips as he covered her left nipple, and gently sucked it. "Doesn't that feel good, Kate?" "Ohhh... yesss..." she whispered as he gently sucked her other nipple, with his tongue licking back and forth over it as he sucked more of her breast into his mouth. Kate loved it so much and she couldn't stop moaning with pleasure. "Gently bite, Erik," added doctor. He delicately bit her erect nipples. Kate whimpered. "Ahhh... yes... bite harder, please... please honey..." "Do it Eric. Mom obviously loves mixing a little pain with pleasure. Believe me Erik, sensual biting can be a very pleasurable experience for a woman. It is something many of them secretly yearn for. However, remember, every woman's threshold for pain is different, so you may need to adjust your sensual biting technique before you really hit the spot. And you'll know when you have -- the moaning and writhing will be a dead giveaway." Erik bit mom's left nipple harder. Kate moaned loudly. He did it again and again. "Bravo Erik! Mom's body reacts to your moderate pain in the same manner it reacts to your skilled mouth or tongue: with instant arousal. Look at your mom squirm with desire!" Kate gasped, caught up in the electric current running through her body. "Don't stop honey... please. Ohhh... I'm cum-m-m-ming," she was panting with each bite as her body shuddered with a massive orgasm. "Damn mom. You are so hot!" Erik shouted. "Yes Erik, your mommy is fucking hot. But easy, now mom's nipples are so sensitive," Dr. Wood warned him. Erik reluctantly released the swollen nipple from his teeth. He couldn't believe what had occurred. He had just sucked and bit his mom's nipples and caused her to have another orgasm. It took Kate a minute to catch her breath. Dr. Wood waited and softly massaged her heaving breasts and cuddled and kissed her until she could talk again. "That was...incredible, I enjoyed it so much, doctor. Is it ok?" Kate finally managed to gasp. "Yes, yes my darling. I told you it is ok. You are so horny .... and I know you need more... I understand your high sexual urge ... For that reason just relax and enjoy." Then she said to Erik. "Excellent Erik! You made your mom cum again! However, mom's pussy is on fire and need serious attention. I think mommy cannot wait any longer; she needs your big fat cock. She too was primed for sex! Don't you, Kate?" she said teasingly. "Yes... please... I need his big cock ... so much," gasped Kate. "Well, I'm glad I'm hearing it, Kate. Help him to penetrate you!" the doctor said keenly. Kate brought her long legs up and wrapped them around her son. Her swollen vulva was spread wide open and she used her hands to make sure that his throbbing cock was pointed straight towards her eager pussy. Kate slid that massive cock-head into her pussy, then pushed on Erik's ass to help him slide into her. "Erik, I will give you some advice while you're fucking your mother. Listen to me carefully and try to do as I say." Erik nodded. "First, be patient. This time I want you to last longer while fucking mommy. Try not to cum too quickly. Each time you're on the verge of ejaculating hold yourself back and think about something else. The more you practice holding back while fucking mom, the better you'll get at controlling your ejaculation. Remember, your mom likes and wants a long slow tender fuck with deep pounding." Erik nodded again and started fuck his mom carefully, first with short little strokes, slowly opening her up, driving further, feeling the sensation of her hot channel allowing him in. Dr. Wood was pleased that Erik obeyed her advice and entered mom slowly, inch by inch while Kate's breathing was becoming a more and more rapid. "Mmm, mommy is enjoying your penetration, Erik. Some men believe that unvaried, deep, and quick thrusts are the most effective, but in fact this is rarely the case. At the beginning of mating, you can give and receive much more pleasure by moving slowly and keeping the penetration shallow. Later, mommy will prefer long and deliberate movements in which the tip of your cock is withdrawn toward your mom's vaginal opening before each new deep penetration. The reason for this is simple: with your mom's sexual excitement mounting, the inner portion of her vagina widens while the outer third narrows as it becomes congested with blood. In other words, it is the outer third of your mom's vagina, which provides the greatest stimulation for your cock. Furthermore, you change your thrusts from deep to shallow, and you also let your cock rotate deep inside mom's pussy with a circular forward and backwards motion of your hips." He tried to do what the doctor said. Mom's moaning proved that he was doing a good job. "Talk dirty to your nasty mom. She likes it, too," added the doctor. "Mom, your pussy is too tight and warm..." "Ahh yes honey... it is because your cock so big." "Do you love my big cock, mom?" "Yes, I love the way you feel inside me. I feel so fulfilled..." "Are you my slut... my bitch?" "Yesss, I am yours," said Kate in a husky voice. "Erik, kneel and sit on your ankles, between mom's thighs. Now, raise your mommy's legs higher, lift her knees to her chest, and hook her ankles over your shoulders. Support your weight on your hands," the doctor said. Erik did it, he grabbed her thighs, so that her calves were resting on his shoulders while her bottom and lower back was elevated. This angle allowed him to penetrate her deeper than before. "Ohhh, Erik, I can see your massive cock is stretching and filling your mom's womanly channel. Remember, once she has an orgasm DON'T STOP! The female orgasm cycle consists of excitement, plateau, orgasm and resolution. Mommy will have an orgasm and think she needs a break. However, if you continue to stimulate mommy throughout the resolution stage, it's entirely possible to trigger orgasm after orgasm, resulting in a multiple orgasm. Don't stop and mommy will recover and be ready for an even more intense second orgasm. Slowly increase your speed and pressure and she'll come again and again and again!" Kate was moaning with every thrust now! She had never been fucked as deep as she was being fucked now and his cock seemed to fit better than it ever had. Erik's huge cock pistoned in and out of his mom's tight pussy, his big floppy balls slapping against the sweaty crack of Kate's ass again and again. At that, she began to cum and groan more loudly, interspersed with gasps of, "Oooh... yes!" "Oooh, god... yes! Ooohh, yes, yes... I'm cumming! I'm cumming! Ohhh, god, yes! Mmmm, make me cum, aaahhh..." "Mommy is cumming, but do not stop fucking her. Do not let her excitement disappear. Slowly rock her in a side-to-side and up-and-down motion to bring the head and shaft of your cock in direct contact with the cervix and walls of her vagina," Dr. Wood reminded him. Kate just thrashed and moaned as Erik continued fucking her pussy while the doctor was pulling her nipples. "Now, slowly increase your speed and pressure and mom will come again and again..." Kate hissed, "Yes, honey... fuck me! Fuck me... please!" She thrust her hips against him, eager to come again. After just a few seconds, Kate's next orgasm built and thumped through her belly quite quickly and she was fucked through that and on into another and another. Erik couldn't believe his mom climaxed so quickly and so many times. He slowed down, but he did not stop fucking her. He performed a grinding movement, using his hips to mimic a rotational motion. Then, Erik lowered his sweaty body down on top of his mom's and kissed her eyes, the tip of her nose, and then her wet lips. His cock thumped and throbbed, still lodged deep inside her pussy. "Wow, it was so amazing! However, now it's your turn, Kate. Mount your lovely boy and his big cock!" Dr. Wood said. Erik helped her to get on top so she could mount him. "Oooh, God! It feels so good," Kate moaned. Now, she had much more control over depth and the angle of penetration. She was changing the angle and rhythm of penetration as she pleased, by rocking backwards and forwards and from side to side, swiveling her pelvis or moving up and down. She moaned when she felt his penis touched her cervix over and over again and this just made it all the more exciting for her too. "You love his big cock, don't you?" asked the doctor. "Yes, I... I love it so much..." Kate said wantonly, "I've never had one that... big before." "I understand, darling. Curvaceous woman like you with a deeper vagina would definitely prefer a well-endowed man with a longer member," Dr. Wood said softly. Erik looked at his mom delighted but unable to believe what he was hearing and seeing. "Wow mom, you are so fucking hot... you're the hottest woman I've ever seen!" Kate just moaned and leaned forward to kiss her lover. She wanted him so much and now all of them knew it. Then she leaned back to let his cock pushed against her g-spot on the front wall of her pussy. Dr. Wood noticed that and saw her huge clit totally exposed. "Look at mom's lovely clit Erik. It is very easy to stimulate her clit in this position," Dr. Wood suggested. Erik immediately did that and Kate moaned with pleasure. She was shaking all over with excitement. The position allowed her to take him deeper and she was delighted with every inch that invaded her. Her pace quickened until she frantically bounced on his lap, reaming her pussy on his thick cock. "Oh darling, you are about to come again!" Dr. Wood noticed it, but didn't hide her excitement and pleasure, "Erik, mommy is becoming a real cock slut for your cock. Congratulations!" Kate could not answer. A new orgasm ripped through her gorgeous body. She only wailed, in a crying tone. "Ohhh my .... ahhh...!" She shuddered and twitched through her orgasm for a good long time before she finally stopped shaking. Dr. Wood let Kate ride this orgasm out and catch her breath, and then said. "Erik, it's time to switch positions again. Remember, making love in different positions hits mom's orgasmic centers from different angles. So, turn your mommy over into a doggy-style position." Erik took mom by the hand and helped her up from his lap carefully. Kate disappointedly moaned as his cock pulled out of her. Although she orgasmed so strongly, she felt she was still unsatisfied. She wanted him so badly that she quickly dropped to her knees, faced away from him, and pushed her ass in the air. Her back was dropped fully, her knees was nicely parted. He crawled behind her, placed his hands on her cheeks, and spread the pliant flesh, revealing the wet hole awaiting him. Kate moaned and wiggled her beautiful rounded ass openly and wantonly inviting him to fuck her. "Erik, look at mommy's body language! Her body says, 'I am ready and I want to breed right now.' She placed herself in the most functional, most stable, most easily accessible position for deep penetration. I call it "acting the slut." Her lower back arches down deeply. This makes her hips tilt upwards, exposing her fat pussy lips. Her upper-legs are vertical. Any deviation the vertical would cause her vaginal entrance to face either up, or down. Her calves are parted to allow the male to stand between them. Finally, her knees are parted a suitable distance. This makes her stable when the male climbs onto her. It also facilitates ease of penetration. In addition, instantly, she becomes sexually available! Your mommy is a very talented and skilled woman! Remember this, when you fuck a young and inexperienced girl." Erik listened carefully and nodded. "Slide your cock-head along mom's large, succulent pussy lips and tease her," the doctor ordered him. Erik did, and Kate was swaying her hips in a soft, rhythmic motion while humming to him, "Ohhh... I'm sooo horny, honey. Fuck me, pleeease!" She glanced over her shoulder, and gazed up at Erik lustfully. "Slowly penetrate your mom," the doctor added. Kate moaned when Erik entered her shallowly. Simultaneously, the doctor reached around Kate and grabbed one of her heavy breasts. Dr. Wood squeezed and tweaked her nipple between her thumb and forefinger, sending electric shivers in a direct line to her clit. Kate couldn't help but slip a hand between her thighs and rub her distended clit. Dr. Wood noticed it. "Kate, you're so horny and eager to mate, aren't you?" With her other hand the doctor caressed her clit for her instead. "Yes, I am... ahhh... let him fuck me ... pleeease," she moaned and pushed her hips back until she felt his thick shaft slide deeper into her tight pussy canal. Erik started slowly, going in and out almost the entire length of his cock, leaving only the head inside her stretched pussy. He steadily sped up until he was really driving into her forcefully, trying to get as far as he could inside her. Kate dropped to her elbows and her ass pushed more in the air giving them a full view on her little sphincter. Erik's Transformation Ch. 04 "Mmmm, look at mom's throbbing anus. It's asking for your attention, Erik!" Erik's hand slid between her firm rounded ass cheeks and the tip of his thumb flicked against her tight pulsating anus. Kate gasped. He touched the tight ring again. Each time his thumb dragged over her anus, a quiver washed through her, making her more and more excited. She was so incredibly stimulated! Erik's cock was massaging and pressing her cervix, while Erik's hand was grinding her ass hole. The doctor was caressing her clit and tummy, while the doctor's another hand pinched her nipples! Almost immediately, she felt the powerful surge of orgasm well up in her body. "Harder... please...Go deep! DEEP!!!" Kate begged. "God...I'm going to cum... again... ohhhhhh... I'm cumming!" A massive orgasm took her by surprise, wracking her body with shock after shock of erotic delight. Erik felt so powerful, controlling her that way, but had to exert all of his willpower to delay orgasm. He slowed down, rotated his cock deep inside mom's pussy by a circular forward and backward motion of his hips, as the doctor had said to him earlier. "It's okay, Erik. You succeeded in controlling and delaying your cumming as long as possible. Now fuck your mommy harder and cum deep inside her hot pussy... give her full load of cum ... fill her pussy ... mommy loves that!" Dr. Wood encouraged him. "Yes honey, fuck mommy harder... please... mommy needs that!" Kate begged again. Erik started fucking harder. He was pounding her so hard that her large full tits bounced with every stroke in and out. He was plowing mom's pussy and she was moaning and squealing so loud that the doctor was afraid the neighbor would hear her. Kate was making almost animal grunts in rhythm with Erik's thrusts into her swollen pussy. She quickly achieved another massive climax and Erik felt his mom's pussy squeezing and her juices flowing in her already wet cunt. Dr. Wood noticed that Kate's juices were dripping out of her pussy. "Ohhh Kate, you ejaculated! Relax, don't worry about the mess you made," said Dr. Wood enthusiastically. "But ... how... ahhh... I've never ejaculated in my life..." said Kate, breathing hardly, "I feel... ahhh... like I've got to pee..." "Most women who ejaculate say it! However, its not pee. It is female ejaculate and happens as a result of direct, firm, prolonged g-spot stimulation. Relax and enjoy it, darling!" Kate tried it and from the swelling of Erik's cock, she knew he was close. She thought of his boiling seed filling her and she increased her pace, urging him to cum in her pussy. Once again she could feel her pussy wanting to cum again, to cum with him this time. He rammed forward and exploded! The first shot of his hot cum sprayed all over the walls of her hungry pussy. Her cunt hole was filled with her juice and his thick sperm. He came so abundantly it started to overflow. More of the juices were oozing out of Kate's pussy onto the bed sheets. Her orgasm was starting as soon as he began to shoot. She screamed one last time in orgasm and collapsed face down into the pillow with Erik's massive cock still embedded in her pussy. He stayed inside her about a minute and then slowly pulled his cock out. They were both damn tired and he lay down beside her. Kate turned over and pulled him close to her as she felt the afterglow of tremendously satisfying sex. Dr. Wood could see some of his cum leaking from Kate's swollen, tender pussy. "Oh my...it's wonderful ... Well done Erik, you've endured fucking almost 45 minutes and you made mommy sooo happy," the doctor said teasingly before rising up and kissing Kate on the lips. "I'm sure mommy needed that! I believe I saw and heard some nice orgasms in those 45 minutes of non-stop action by Erik. Are you satisfied now, Kate?" "Yes, yes... I am very satisfied... That was incredible. I had so many orgasms I lost count... It seemed to be happening non-stop" Kate blushed and replied in a soft voice, "I have never felt so aroused or turned on." "Kate that's great! I am glad to hear that," Dr. Wood did not hide her pleasure. "And that was the best fuck I've had in my life... Thanks honey! And of course, thanks Dr. Wood. Without your help it wouldn't have been as nice as this," continued Kate. "You're welcome," answered Dr. Wood, "I'm here to help you. What about you, Erik?" "I had no idea that fucking mom could be so good. Hitting mom's cervix with my cock-head and her orgasms are the best parts of fucking. I love you mom," Erik answered. "I love you to honey," said Kate innocently. "Kate, do not forget to give Erik relief before bedtime. He came a lot less this time than you," the doctor reminded her. "Of course, don't worry, I will not forget it." "Now get some rest. You both deserve it! See you soon," said Dr. Wood and left them. To be continued... Erik's Transformation Ch. 05 Many thanks to Seereeoslee for editing and improving this. Three days passed since Dr. Wood visited Kate and Erik. She was anxious to hear from them. Did Erik make progress since he started the second phase of his treatment? Did Erik still feel insecure around sex and females? How did fucking his mom help him? Finally, Dr. Wood called Kate. "Dr. Wood speaking. How are you, darling?" Dr. Wood asked, a little concerned. "Ooo... fine ... fine," Kate replied with surprise in her voice. "I was worried. Is everything all right?" "Yes, yes, everything is ok... " "I expected you to call me," said Dr. Wood little angrily. "Sorry, I wanted to, but I took some time off from work and... all time I was dedicated to Erik," Kate answered hoarsely. "Oh, I am glad to hear that." Dr. Wood realized that there was no reason to be mad at her. "How is Erik?" "Erik is great. I am so proud of him. How would you put it? He is very quick on the uptake ..." "Very nice, Kate. I told you that your help is the key to Erik's success! So, can I see both of you tomorrow at 10am? I want to verify that Erik's self-confidence has increased. "Yes, it is ok. We'll be there. See you tomorrow." *** The next day Kate and Erik visited Dr. Wood again. Dr. Wood was pleasantly surprised by Kate's appearance. She had cut her hair short, and dyed it red. Her make-up emphasized her full and pouty lips. She was in a tight, silky blouse and her round breasts were pushed together, forming a mountain of cleavage. Her miniskirt hugged her ample curves and the heels of her pumps made her legs look impossibly long and shapely. She was definitely hot and sexy. "Kate, my god, you look absolutely radiant!" Dr. Wood welcomed them with a broad smile. "You look brighter, tauter, and years younger ... and... like you've lost a bit of weight." "Thanks," Kate replied in a soft voice, blushing. "Obviously you felt good while teaching Erik. And you've really enjoyed yourself, haven't you?" "Yes, a lot," Kate admitted, and blushed again. It was clear that the doctor assumed that her good looks were the result of her fucking Erik. "Bravo Erik, you made your mommy very happy!" Dr. Wood turned to Erik. "Happy and satisfied!" "I did my best. She deserved it; she helped me a lot. I have had a great teacher," Erik said proudly. "Nice, Erik! Did you enjoy fucking your horny mom?" Dr. Wood asked him with a smile. "Ooo yes, yes... very much! Getting to fuck my mom had been so incredible," Erik answered happily. "Very well. I can see that you both are much more relaxed in your relationship, right?" They both nodded, confirming doctor's words. "Your advice from the last time helped us to relax a lot. Thanks again," added Kate softly. "You're welcome. I'm here to help you. So, tell me how did you spend the time since our last meeting? How many times a day do you have a sex?" "So...I think four to five times a day," Erik answered and looked at Kate asked for her confirmation. She just nodded. "Wow, you fucked your mom four or five times every day? Obviously, both of you were horny all the time! Congratulations Erik, you are so potent!" "Well, err ... It was not hard for me. When my mom told me I could fuck her when I feel the urge, anytime and anywhere, I felt free. And I had a strong urge for sex all the time," Erik said passionately. "What! Ohhh, Kate, you're a really naughty girl. Why did you tell him that he can fuck you anytime and anywhere?" "Well... I thought it was best to do nothing to force Erik. I wanted to adjust to our new relationship... I wanted him fuck me when he felt the need... I wanted Erik to be relaxed. I mean, I wanted to do my best for Erik for medical reasons," Kate explained, trying to justify herself. Then she added, "God, I hope that was ok. I'm so embarrassed!" "Don't be silly, Kate. It's all very natural. I'm sorry if I've caused you embarrassment. I understand; this way Erik was certainly more relaxed. As I told you, it is very important that your relationship be natural and relaxed." "Yes... yes," Kate confirmed with relief. "And I requested her to be naked all the time while she is in house. The most I ever allowed her to wear was a tiny thong and bra set. I like when her large tits and pussy lips are visible all around," added Erik. "Well done, Erik. So, tell me where did you fuck your mommy? In which places?" asked the doctor. "Well, all over the house. I fucked mom in her bedroom, in the kitchen, the bathroom, living room, on the stairs, in my room ..." Erik replied without hesitation, with a touch of pride. "Wow! Obviously you were always with your mommy and you used every chance to fuck her. I'm glad you heeded your mom's request to fuck her whenever you felt the urge. The more that you have sex with your mommy, the more it will increase your self-confidence," Dr. Wood smiled. She liked that Erik had his mom remain mainly nude while at their house, readily accessible. She was sure he fucked her constantly, dumping load after load into her hungry pussy. "So, I want to hear more details. Kate, after I left you, did you give Erik relief before bedtime?" Dr. Wood continued. "Yes, after you left us we had to rest. I was so tired, you know ... after..." Kate paused. "I know, you were tired after Erik fucked you so hard. That is understandable," Dr. Wood encouraged her. "Yes, I needed to sleep and I went to bad earlier than usual, but before that I gave Erik a quick blowjob." "You swallowed his load, I guess," Dr. Wood teased. Kate sighed and, shaking her head, exclaimed, "Yes, I love the taste of his cum! It tasted so good, so thick and sweet." "I know you like it. Obviously you are turning into a cum fiend. Go on Kate." "Next morning, I awoke to his fingers touching me, caressing me, exploring me... I felt Erik's hand on my... err... pussy," Kate paused again, she was undecided how to continue. "Does this mean that Erik is sleeping in your bed, Kate?" "Yes," Kate replied shortly and continued, "He moved into my bed... Is that ok?" "Of course, Kate. Perfectly! You should behave like real lovers. And...?" "And... I assumed that he needed relief and I spread my legs wide apart to give him better access. "Well done Kate. I'm sure that Erik needed relief. In the morning, men are always craving sex. Additionally, he has got his hot naked mom in bed with, and she's willing to do anything he wants. Keep going, my dear." "I felt Erik's fingers smearing my juices over my lips.... waves of excitement flooded through my body as he gently charged first one, then two fingers in my pussy. Oh... his thumb circled my clit with the perfect pressure and pace and I moaned in ecstasy without restraint. I wanted my son to know how much I liked it," Kate continued, a little braver now. "Yes, it is important, Kate, to be loud! In this way you are telling Erik that you enjoy his touches. But, you said you felt Erik's fingers in your pussy. Does that mean you were sleeping without panties?" Dr. Wood asked teasingly. Kate blushed and in soft voice replied, "Yes, at his request I was not wearing panties. Actually both of us were totally naked in bed. I've found that like to sleep naked and I enjoy the touch of Erik's naked body. Is that ok?" "Of course, Kate. Great! I am very pleased with you. I am glad to hear that you were sleeping together in your bed completely naked! It tells me that both of you are more relaxed. Continue Kate," demanded the doctor. "Well, after a few minutes Erik got up and placed himself between my legs. I felt his hard cock between my thighs and I spread my legs more. Then Erik penetrated me and began pounding stronger and stronger thrusts into me. He was kissing me... he caressed me... he sucked my nipples... My legs were open very wide and pulled back to my stomach and he penetrated me deeply... ooh my ... I had the urge to tell him how much I liked deep penetration. I told him I wanted his cock inside of me... fully inside of me. I think that drove him wild and he groaned and he came. I felt every heavy twitch, every hot blast of cum ejaculating into my depths," Kate finished breathlessly. "Oooh, it sounds like it was fantastic, Kate! I guess he was very excited and he could not last longer while fucking you. Were you having trouble reaching orgasm?" asked the doctor. "No, no... he fucked me furiously for about fifteen minutes. And that was incredible. I must have cum at least ten times," timidly replied Kate. "Mmmm... mom's milking pussy was amazing. Her orgasm seemed to be happening non-stop. Her hot pussy spasmed and I had to cum quickly!" Erik tried to explain. The doctor nodded, approving. "You were great, Erik. I've noticed that your mom is multi-orgasmic and once she starts into her 'Big Bang' she will be rocked by hard orgasmic waves sometimes lasting five to ten minutes... I know, in those moments it is difficult for you to delay ejaculation. However, you fucked mommy for fifteen straight minutes! That is good for a first day fuck and it is even better for an average fuck session." Then she said to Kate, "Tell me about another time he fucked you." "So... it was... immediately. He did not stop... his cock was still hard so he just continued to fuck me," Kate replied. "Wow Kate, you know that a majority of men need 'break time' to rebuild their strength and allow their cocks time to feel excitable again. But Erik is like you, he may be stimulated to another orgasm immediately after having one. That is why he stayed erect after orgasm! I'm sure he fucked you longer this time." "You are right, Dr. Wood. He fucked me for a very long time, about an hour. At first he was gentle and he was kissing me tenderly. He started fucking me very slowly and gently, in various positions. Then he continued to fuck me harder and harder and I cried out in pleasure... I was completely at the mercy of his cock. I was fucked hard and rough and I liked it! Finally, we collapsed onto the bed in exhaustion," said Kate now much more confident. "I hope you had a good rest after your rough and wild fucking!" Dr. Wood smiled. "Yes, I needed a rest and I slept for about an hour. When I woke up Erik allowed me to wear only a T shirt, without bra or panties. We had breakfast and then Erik helped me wash the dishes and clean the house. He was close to me the whole time, completely naked and he used every chance to caress my butt, boobs, pussy. Of course, I was entirely comfortable with this and never objected. He was caressing me the right way and I tried to give him the message that I was enjoying his attentions. I moaned ... I purred... sometimes I caressed his balls and cock. After two hours of such play I felt his hard cock massage my butt. I just bent over and pushed up my ass. When I leaned forward a bit he entered me from behind in one quick motion. You know, I love that position because of the deep penetration. I found that the farther I leaned over, the deeper he could get. And if I felt like he was thrusting too deeply, I could adjust my stance so that I wasn't bent over so far and the thrusting was suddenly shallower," explained Kate still blushing, however she was much more relaxed and she was enjoying sharing her story. "Great, Kate. Obviously, you learned too! How long did he fuck you this time? How many orgasm have you had?" "Errr... Erik fucked me about forty-five minutes. You know... I liked doggy style... when he would penetrate me so deeply. I would cum easily and I could just keep on going for hours. I think I had at least four long multiple orgasms. So if I am counting each of a multiple orgasm as one, that number could be really high, about twenty-five or thirty!" "Mmm... I believe that under the right circumstances you can just keep on going for hours. You are lucky boy Erik. Your mom is so horny and I don't think there's actually a limit for her! Continue, Kate." "So... the third fuck session was around 5pm in Erik's room," continued Kate. "Erik was lying down on his bed and reading a book. I knew that his testicles were full of sperm. I approached him and started to fondle his testicles ... I mean ... balls. Then I swirled the tip of my tongue around his scrotum. I licked his balls with long, sweeping strokes then I took each testicle all the way into my mouth." "Bravo, Kate! I like that you showed initiative. Sucking on his testicles can make for an incredibly sensational experience - and you'll double his pleasure if you simultaneously fondle his shaft," Dr. Wood commented. "Yes, I did that... and he was quickly hard. Then I began to suck his appetizing cock. I relaxed and took him all the way to the back of my throat. God, I like to feel his hard cock in my mouth," Kate said with excitement in her voice. "Did he finish in your mouth?" "Not that time. I stopped sucking and I got on top of Erik, facing him. We started in this position but without penetration. Erik kissed me and we made out for a while. However, I was so ready ... I needed his rigid cock ... and... I lifted my hips and he pushed into me. He repeatedly penetrated me deeply and after a few minutes he said, 'Mom, you know how much I love your butt. Why don't you swing around?' I must have looked a little panicked because he laughed and said, 'Relax. You can get up and reposition yourself.' I pulled away and sort of half crouched over him and waddled around so I was facing his feet. He re-entered my pussy and... it was... amazing! " "Yes! I know you like to be penetrated from behind and this position is similar as doggie-style. The angle is perfect for G-spot stimulation. And even better, this position leaves the guy's hands free to reach around!" "Yes, he squeezed my breasts and my butt; he used his fingers to tease my nipples. He kissed my neck. He fucked me for about an hour and I achieved five or six long multiple orgasms. When I noticed that he was ready to ejaculate I stood up and took his cock in my mouth. You know how much I love his ... err his hot sperm. Soon, he was filling my mouth with a big load of sperm that only a young man could produce. And I swallowed all." "Mmm... very nice... Continue please," Dr. Wood said, contented. "The fourth fucking was around 8pm. We got it on in the kitchen..." "I'm guessing Erik took you from behind, right Kate?" the doctor asked, her voice husky. "Err, yes he did," Kate replied. "Erik was sitting at the table while I prepared dinner. I was wearing just a short, sexy lace nightgown and high heels. I had no panties... and I knew he was watching me closely while I walked across the kitchen." "Wow, transparent nightgown and high heels! You acted like a slut, right?" asked the doctor. "Yes, Kate replied blushing, "I wanted to look provocative and for Erik to consider me hot and sexy." "It's totally ok, Kate. What was Erik's reaction to your near-nakedness?" "He told me how sexy I am... and... he got up and approached me..." "Mmm... It tells us that Erik loved you to dress for him in what we might call 'stimulating clothing'. You have to constantly strive to be accommodating for Erik." The doctor encouraged her again, "Go on..." "Erik's hands were immediately all over me. He pushed me up against the wall and kissed me. Then he kissed my neck. Ohh... I like neck kisses; they have the ability to make me instantly hot and ready. I reached down, grabbed his huge cock and started to give him a hand job. Then he put me on the kitchen sink, my butt was hanging off the edge. I was propping myself up on my elbows, which were on either side of the sink. I laid back, lifted my pelvis and wrapped my legs around him. Our faces were close and he kissed me. When he lifted my butt off the sink, it felt ama-a-zing. Then he penetrated me slowly and deeply. And I loved that Erik could do sort of a reverse thrust... he stood still, put his hands on my waist, and pulled me towards him. He was moving really slowly and I orgasmed really quickly that time." "When did Erik cum?" "After half an hour. His orgasm was so strong. He fucked me all the way through it, stream after stream of cum pouring into me, until he was spent. He was great. He knows I like long, drawn-out sex... he knows I like to be fucked for hours. I achieved four long multiple orgasms again," Kate finished breathlessly. "Mom was amazing, too," added Erik. "When I slowed I could feel mom's pussy clenching around my cock. Wow, she orgasmed the whole time I fucked her. However, when I stopped moving she was still coming! So I started screwing her again, short, fast strokes, for as long as my stiffness would hold out." "Great Erik. That was not the last fuck before bedtime, though, was it?" the doctor asked a bit astonished. "Err, you are right," answered Kate. "We didn't go to sleep until about 11 o'clock." "I guess both of you were naked in bed, right Kate?" Dr. Wood asked. "Yes... I was relaxing on my left side with my back to him and Erik hugged me tight from behind." "You mean he hugged your hot naked body! And soon you felt Erik's erection on your butt?" "Yes..." "Of course, Kate. What else could you expect from a young stallion? Tell me how Erik fucked you this time." "Erik ran his hand over my breasts, then over my belly and my pussy. He caressed me all over my body and I loved it. I bent my right leg at the knee so that Erik had better access to my pussy. Erik even raised my right leg in the air and held my legs tightly with his left hand. Now he had an excellent approach to my widespread crotch. With his right hand he fixed the top of his cock at the entrance to my pussy. I was so wet and Erik shoved deep into me in two or three jerks. He fucked me with long slow strokes. I was feeling his full length penetrate me repeatedly. With his right hand he stimulated my swollen clit, he pinched my nipples, and he squeezed my boobs. He teased me and asked me repeatedly if it felt nice, even though I was moaning loudly. Then he turned me onto my back. He was holding my boobs and squeezing them... it felt amazing. I wrapped my legs around him and he pushed into me. He was going so deep and was being so rough. I love when he is rough. I reached up and put my hands on the wall behind my bed. It makes my tits look super perky! He kissed my tits and lips and started thrusting faster and faster. I could hear the clap as our bodies hit each other. I came hard several times ...and finally I felt his hot cum fill me," Kate ended describe panting. It was clear that she had gotten herself very excited. "So you two spent a wonderful day together, fucking. Was it that exciting on the other days?" "Yes, yes...except Eric had more initiative. And... he was getting better and better... you know..." Kate trailed off unable to complete the sentence. "Yes, I know. You mean he was getting to be a better and better lover and he was fucking you better and better!" Kate opened her mouth to reply, but nothing came out so she just nodded. "It is because he has a magnificent teacher! His teacher is an extremely beautiful woman with an amazing body! Am I right, Erik?" "Yes, mom is beautiful and very hot and I love her amazing body. I love her big full breasts and her large sexy ass, everything about her to me is perfect. And I could not stop fucking her..." "Yes, I know that. I've just heard how often you fucked your mom. That's proof enough for me," doctor said with understanding. Dr. Wood thought for a moment, then looking to the Kate, she said, "Come to think of it, I am not surprised that Erik fucked you so often, Kate. You stimulated and motivated Erik in the best possible ways. There is nothing more stimulating for a young stud like Erik than having permission to fuck a constantly excited female like you when and wherever he wants. Bravo Kate!" Erik's Transformation Ch. 05 Kate flushed but nodded and quietly confirmed. "Was it hard for you to adjust to fucking on Erik's 'schedule'?" Dr. Wood asked Kate. "Er.. it was not hard for me. Honestly, I was not aware of that I was fucked so many times," Kate replied blushing. "The first day I was a little sore. Mostly the muscles in the groin and abdomen. As you know I have not been with a man in five years. But the pain disappeared quickly and I got used to the frequency of Erik's urges." "Yes, I know you have not had regular sex for a long time. Muscle soreness was expected due to prolonged interruption in your sexual activity. But, if you were not aware of how many times you've fucked it means it was not hard for you and you were really enjoying all of the sex." Kate nodded and quietly confirmed again, "Yes, Dr. Wood, I was really enjoying it." "I must congratulate both of you, again. Especially you, Kate. Your son should be very happy that his mom is a beautiful woman with a very high libido and a strong urge to fuck. Erik, it may surprise you to hear that there are few people who would be ready to have sex all the time, like your mom. My conclusion is your mommy is always sexually aroused and able to express her love for you by having sex!" said Dr. Wood with a smile. Erik agreed entirely. Obviously, no matter what the time, his mom would liked to has sex with him. He liked the doctor so quickly discovered and proved that his mom really enjoyed fucking with him. Both of them were amazed at how their body were reacting to this conversation. Erik's cock was hard and he thought he would explode. Kate was red in the face and she felt a spurt of her juices, soaking her already moist panties. "So Kate, do you think that your new relations with Erik have made you more libidinous?" Dr. Wood continued with provocative questions. "I guess. About time I had a man that could make me feel good! I feel aroused most of the time. Is that ok?" Kate asked uncertainly. "Yes, yes... it is ok, Kate. There are many reasons for feeling more lustful. When starting new relationships, sex can be very enjoyable, especially if a woman has been sexually inactive for a long time, like you. In addition, as you and your son got more comfortable with each other it got more satisfying and you enjoyed having sex with him even more," Dr. Wood explained. "But, it seems I'm aroused all the time whether Erik is stimulating me or not. I am constantly thinking about sex," Kate added. "Of course, Kate. As a woman gets older, her appetite for sex can grow immensely. Your sex drive actually increases with age. Now, you are in the prime of life and in magnificent condition," Dr. Wood explained. "In addition, a woman's sex drive is more likely to be aroused by desire for her partner, by pleasant surroundings and a relaxing situation that encourages affection. I guess you'll agree with me that you now have all of that, especially a partner with a desire to engage in numerous sexual activities . Another factor: your partner produces an unusually high amount of sperm. Most women are impressed by powerful and voluminous ejaculations, like Erik's. Women enjoy such big ejaculations mostly for psychological reasons. Each woman instinctively desires to be with a healthy, protective and fertile man that cums in great loads. Lots of cum during ejaculation excites you because it makes you feel pretty and sexy. And it flatters your ego. Is it true, Kate?" "Yes, it is true," Kate confirmed obediently. She felt relieved that the doctor understood her sexual urges and added honestly, "I enjoy having sex with my son. I like it so much! It was never enough for me..." "Kate, I understand. When you are sexually active, your genitals stay primed for sex and your body is in the habit of 'turning on'! So just relax and enjoy in your testosterone-filled young man," Dr. Wood smiled. "I love how my mom is so sexually active and horny. She is such a horny slut," Erik added. "You are right, Erik. It's every woman's prerogative to possess elements of the slut. Your mom possesses elements of the slut too. I think you have woken up mom's slumbering slutty side." "I... I have? " Erik stammered. "Yes. Thanks to you Erik, your mommy has become a fiery little slut, who will do anything and everything you ask her. I think that you understand that and you know that from now you have to take care of your slut." "Yes, I understand and I will take care of my mom... my horny slut," Erik said happily. He reveled in the knowledge that his mom was a slut. "I am glad to hear that. Now, do not forget that your slut needs to be fucked regularly. You are going to have to make sure she gets plenty of hot thick sperm loading up her throat, sloppy pussy and womb. First thing every morning. You should fuck her before she goes to work. When your mom arrives home you should fuck her again. If you do not have a lot of time, you should fuck her quickly. You cannot leave your mom without afternoon screwing! In the evening you should fuck your slut at least once or twice. You need to make sure she is getting fucked long, hard, and in many positions, until she cums. At least once a day your slut should suck your cock until you blow a massive load into her mouth. Do not forget, your mom is turning into a cum fiend and loves the taste of your sperm." Kate listened with disbelief. Dr. Wood was speaking of her as a terrible slut! Then she realized that the doctor is right. Erik could not take it anymore. The doctor's speech and advice had made him so horny that he wanted sex immediately! He turned to his mom and said, "Do not worry mom, I'll take care of you." He slid his right hand along her bare thigh. Kate flinched, she was completely bewildered. Dr. Wood noticed her confusion. "Relax, Kate. You are your son's horny slut and you now have to be obedient. You said that you would let him fuck you anytime, anywhere," she reminded her with smile and continued. "We've had a long talk about your relationship. Erik, I assume that you're already very tense." "Yes, I am very tense. I already feel the pain in my balls. I need to ejaculate," Erik answered immediately. The doctor just smiled and nodded showing that she understood. Then she said, "Kate, I suppose you're tense, too. You're used to fucking regularly and often these days. You probably feel the need to be fucked?" "Ohhh, yes... Dr. Wood. I feel a strong urge to get fucked," Kate replied eagerly, she was not hiding her lust. It was enough encouragement for Erik. He stood up and dropped his pants. His big erect cock sprang free in front of Kate's face. "Suck my cock, you horny slut," Erik ordered her. He gasped when Kate's hand moved and grabbed his huge cock. The gasp turned to a moan, when she started stroking it. Erik placed his hands on her head and she took the tip of his aching cock into her warm wet mouth. "Oooh... mom, how good your mouth feels. You like my big cock, don't you?" Kate moaned softly in reply and continued to suck his cock. She opened her mouth wider and took him all the way down until her lips were at the base of his shaft. She shook her head back and forth and it felt incredible. "You like it when mom sucks you, huh?" Dr. Wood asked. "Oh yes, it's heaven!" Erik answered. "Well done Kate, you are a good slut. You deep throated like a pro." Dr. Wood was impressed with Kate's blowjob skills. Dr. Wood approached her and slowly unbuttoned Kate's silky blouse. She took off it, then took off her little red bra, leaving Kate naked from the waist up. Dr. Wood reached around and grabbed Kate's heavy tits. Kate did not protest, she just enjoyed. She lifted her mouth off Erik's cock and he could feel her breath across his wet member. Sticking her tongue out, Kate began slapping his cock against it. Then she closed her mouth and rubbed his dripping cock head across her face. Erik groaned as he watched her cheeks begin to glisten from his sticky fluid. She acted like real slut. Dr. Wood watched with delight as Kate enjoyed Erik's cock. "That is enough, slut. It is time Erik fucks your greedy pussy," she ordered. "Erik, tell your mom which position you want to fuck her." He chose his favorite one. "Roll over, mom, I want to fuck you from behind." To be continued Erik's Transformation Ch. 06 Many thanks to Tristansparrow and Gora for editing and improving this. * Kate obediently turned her back to them and bent over the edge of the sofa, her legs spread and feet and knees firmly on the ground. Her rounded ass was raised high and her heavy tits swayed. Erik moved Kate's skirt up above her ass and around her waist, revealing her nakedness and her sexy panties underneath. Kate wore a skimpy pair of almost transparent red panties, cut so low that nearly a third of the crack of her shapely ass was exposed. "Wow!" Dr. Wood said standing for some moments gazing at Kate, admiring her beautiful back, her rounded hips, her curvy ass and shapely legs. Then she walked over and stroked Kate's bare thighs, then her lower back and tits to check her position. "I assumed that you would choose this position," Dr. Wood added with a smile, referring to Erik. "This is one of the most comfortable positions of all for rear entry. A large proportion of women find the rather basic and primal nature of sex from behind very appealing. For women, the psychology is of being taken, being totally possessed, and in that possession, expressing the feminine values of generation, acceptance and nurturing. It's the best sex position for deep penetration. In this position your mommy can lean forward as far as she likes; if this lowers her pelvis, you can simply widen your stance so that you can still enter her comfortably." Kate only moaned and nodded. The doctor was right: she loved this position for all those reasons. In addition, it excited to her because it would feel so primal, producing a sense of being helplessly 'taken' by her lovely son, and it could certainly give a great deal of pleasure to her G-spot. While she thought about it, she was instinctively shaking her ass, seductively teasing Erik. He slapped her on that big, bubbly butt and began squeezing and kneading the sides of her ass. "I love your beautiful ass, mom," he said softly, "аnd I love ит when you smell like a bitch in heat!" Kate blushed and continued shaking her ass. She loved it when her son talked dirty. "You are right, Erik," added Dr. Wood, "I can smell the sweet aroma of your mommy's pussy, too. She smells like a bitch in heat, because she is really aroused. I see her panties are soaked through!" Erik nodded. With two fingers he started slowly stroking his mother's meaty pussy lips through her wet panties. Then his fingers wrapped around the rim of her panties and peeled them away. Kate gasped and leaned forward giving her son the perfect view of her swollen labial meat and her puckered butt-hole. Erik inhaled the rich aroma of his mother's agitated twat, taking it deep into his lungs. He could not resist more. He had to taste her! He knelt down and eagerly shoved his tongue up inside her. His tongue felt the heat of her pussy and his mouth instantly filled with her juices. "Oh honey," Kate purred in delight, "that feels sooo nice! Don't stop baby! I love it when you do that!" Erik just licked and swallowed, breathing deep. "You like the taste of your mom's pussy, don't you?" Dr. Wood asked huskily. "Yes, her taste is amazing! And I like her warmth, her smell..." Erik mumbled and continued to lick her slowly, parting her pussy lips, working from the bottom to the top. Then he greedily buried his face in his mom's cunt, stuck out his tongue and licked down her lips, sliding it slowly across her clitoris. He used his fingers to part her lips and looked at her clit. It was prominent and obvious, sticking out just waiting to be licked. Kate groaned loudly while he ran his tongue back over it. He went faster with his licking, closing his mouth around her pussy and burying his nose in her pussy lips. "Oooohhh, my God!" Kate moaned, "Oh... yes, honey! Eat my pussy! Make mummy cum! Mmmm please!" Erik licked as fast as he could. And then with one almighty groan of pleasure Kate came on his face. She bucked heavily, grinding her clit against his tongue and Erik felt a little bit of her juices squirt into his mouth. It wasn't very much, but it was noticeable. He hungrily swallowed her sweet tasting cum, and licked his lips savoring the aftertaste. Dr. Wood watched eagerly as Erik gazed at his mom with pleasure filled eyes. "Oh," she said "He is sooo good at that! Right Kate?" "Yes... yes, he was great," Kate moaned in ecstasy, looking at her son with a lustful, wanton smile of debauchery. Dr. Wood came over to Erik and licked his chin and lips. "Mmmm... very nice," she cooed. "You are right, Erik. Your mom's juices tasted so good!" "Yes, it's the best I've ever tasted," Erik confirmed. Dr. Wood nodded with a smile and slid Kate's wet panties down her long legs. She whispered bluntly, "Erik, rub your cock across your mom's swollen pussy lips, but don't penetrate her, not yet!" Erik stood up and drove his cock between his mom's ass cheeks, guiding his length along her hot, swollen, leaking pussy. Holding it there with his thumb and forefinger, he used his hips to work it back and forth without entering, teasing her further. "Is this what you want, mom?" Erik asked teasingly. "Ohhh God, yessssss!" Kate responded. "Fuck your horny mommy, please!" She grunted as she bucked back against him, trying to get his cock to penetrate her. But, Erik just gently pushed her forward and then lodged his cock head against the slit of her pussy. It was almost as if he had penetrated her. Her pussy was getting even wetter in anticipation: her clit swollen, her lips inflamed. Her pussy juices was all over his cock now. "Oh mom!" he exclaimed "You are so incredibly wet!" "Yes honey," she replied. "I am ready for your big cock... My pussy is so tender and it needs you cock so much! Pleeease, honey, I need you inside of me! Pleeeaaase!" Kate besought her son, unsuccessfully humping her body back at him, hoping he would penetrate her. But Dr. Wood was waiting for just this moment. "I see that you are more than ready for him, Kate," she said. "But before I let him fuck you, I have a few questions for you." "Ahhhh...yes, all right," Kate responded impatiently. "Did Erik satisfy your desires?" "Ohhhh, yes, of course! I am fully satisfied!" Kate answered honestly. "I got fucked by my son like I've never been fucked before!" "It means he has learned a lot, hasn't he?" "Yes... He has learned a lot... and quickly!" "But he has to learn more." "Yes... ahhh... And I like to teach him!" "You are a great teacher, Kate. But Erik has to learn more ... he must practice with other women, too. Are you OK with this, Kate?" "What? " Kate said sharply. "You mean... ahhh... I think..." Kate was confused. She realized that the doctor was proposing that Erik fucks other women. She felt suddenly jealous and excited at the same time. "It would help his self-confidence to increase." "I know... but... what about my needs?" Kate asked timidly. "Do not worry, darling," Dr. Wood said. "You will be still fucked regularly! And you will be completely satisfied, I promise you." "Ahhh... then OK" Kate was unable to talk while her son's large cock-head was at the entrance to her hungry pussy. She could not wait anymore. She needed his big cock so much. "You agree that Erik can fuck other women?" Dr. Wood asked her for confirmation again. "Yes... I agree. Please, let him fuck me now! Pleee-ase!" Her eyes were wide open and dilated, open but not focused on anything. "Thanks, sweetie," Dr. Wood said. Then she took three oversized towels out of the closet and placed them folded and stacked on top of each other on a fleece throw rug in front of Kate. "You know," she said, smiling, "to protect the rug! And you'll be more comfortable down here." More importantly, it gave Kate a sense that it's OK to let go and squirt or ejaculate when she had an orgasm. She hurriedly knelt on the floor on her hands and knees. She was sopping wet from pussy juice and sweat. Her pussy lips were puffy and red. "Fuck my pussy, pleaaasssse! Oh God, Erik, I need your cock!" Kate moaned as she licked her lips and spread her legs wider, exposing her pussy to her son. However, Dr. Wood had a surprise for her. "As a reward for your approval for Erik to fuck other women, I intend to let him fuck you in your beautiful ass instead of your greedy pussy," Dr. Wood said. "What?" Kate exclaimed. "I will let him fuck you in your beautiful ass, Kate," Dr. Wood repeated. "In my ass!? No! I don't want that!" Kate shouted, was still too shocked. "Have you ever been fucked in the ass, Kate?" "Yes ... a couple of times. But... but..." "Great, Kate. I'm glad you're experienced in it. Do you like anal sex, Kate?" "Yes, yes, I like it. But Erik is so huge! Those guys, with whom I had anal sex, had cocks about half the size of Erik's!" Kate said worried. "Don't worry, darling. Your ass muscles are very elastic, so they are capable of a great deal of stretching. The more good experiences and feelings you have with it, the easier it becomes. The more thrusting you can take from your big son, the more you look forward to it. With good experience your anal nerve endings would be developed to make it more pleasurable for you. So just relax!" Dr. Wood said while she gently stroked Kate's wet pussy and all around her asshole, getting it good and slippery. "Wow, you are so wet, darling, so you don't need any lube!" Dr. Wood added. She could tell by the way Kate's ass was swaying back and forth that she was ready to feel a cock inside her. "Do you want to fuck your mom in her sweet ass, Erik?" Dr. Wood asked him. "I don't know... Mom, can I?" "Yes babe, you can have any hole you want," Kate confirmed. Erik could not believe it. His mom had been fucked in the ass! And he, too, would soon fuck his horny mom in her sweet ass. Very, very soon! Dr. Wood gave approval, finally. "Then fuck her, Erik! Fuck your slutty mommy in her tight ass. She needs your big cock, so much!" Erik placed just the head of his cock at the entrance of his mom's puckered little rosebud and pushed. "Ahhhhh," Kate yelped and she winced as the first couple of inches disappeared inside her long unused asshole. "Slowly, Erik. Let her sphincter muscles adapt to your big cock-head," Dr. Wood gave him advice. Erik stopped. Then he continued slowly, moving back and forth, each forward thrust going a little deeper inside his mom's ass. "Is she tight?" Dr. Wood asked Erik. "Yes, mom's asshole is so tight. It's tighter than her pussy!" "Be careful, Erik," Dr. Wood said and asked Kate "You like that, don't you, Kate?" "Yes... yes, I love it," Kate admitted, feeling the pleasure began to build with each of her son's thrust inside her. "Oh, God, fuck my ass harder! Fill me with your big fucking cock," she begged her son and her moans increased as Erik's penetration inside her ass continued to reach new depths. Suddenly, Kate was determined to take all of him. At the same time Erik felt all the length of his cock get buried in mom's tight ass. "Ahhh, yes! Yes! Yes!" Kate kept repeating. Erik was thrusting fast and hard and Kate suddenly had a huge orgasm that took her by surprise. Dr. Wood noticed that and said, "Don't stop Erik! Your slutty mom just orgasmed! Fuck her, fuck her ass hard and deep!" Erik did what Dr. Wood said and kept fucking his mom like a jackhammer. Dr. Wood looked down at Kate's pussy and saw it was swollen, with some of her juices leaking out. With one hand she started rubbing her clit and pussy lips, and grabbed her heavy breasts with her other hand. When she did that, Kate had another orgasm! But this time she started squirting like a fountain and her juices flooded all over Erik. It was too much for him. He wouldn't be able to hold out much longer. "Fuck mom, I'm going to cum!" he screamed out and he came right then and there. "Ahhh... yes honey! Fill my ass! Ahhh... mommy likes it!" Kate moaned contently. As soon as she felt his cum in her asshole, she had another orgasm. Erik felt her ass tighten as she came, and some of her juices got on his crotch again. That was the hardest she had come. She lost her voice, her mouth was open, but she made no sounds. Erik collapsed on top of her. After several minutes, he reluctantly pulled out of her perfect ass and fell back on the sofa. Kate didn't move at first, as she was still recovering from such intense pleasure. Erik and Dr. Wood got a perfect view of her gaping, just fucked ass. Erik's cum leaking out in a slow thin drip. "Fuck, that was good," Dr. Wood said enthusiastically. "Yes, that was amazing," Erik said while panting. "You're my bitch, mom. And I love you!" he added. "I love you, too, honey! That was soooo... good! Those orgasms were very deep inside my belly... it spread all over my inner thighs and up to my chest. Ah, they sent thick waves splashing against all my insides!" Kate was struggling through her panting to describe the pleasure of the climaxes her son had given her. She was exhausted from the intense orgasms she had just experienced. She lay cuddled on the floor and looked absolutely beautiful. Her face was radiant, and her hot body was covered in sweat. "Wow, Kate! You were marvelous! I'm glad you so enjoyed getting fucked in the ass. What a hot, nasty girl you are! There is nothing sexier than a woman who is sexual and knows it and isn't afraid to be sexual. Both of you impressed me with your performance," Dr. Wood couldn't hide her delight. There was silence for the next few minutes. Then Dr. Wood stood up and spoke in an official voice: "Congratulations! Based on what I heard and especially what I saw, I can say that you two have made a great progress in your relationships. You had sex very often, in various poses, in various places. I can see that your hard work and the teaching of your son are both productive, and Erik has learned a lot. Kate, once again, I am very glad that you agreed to help Erik to increase his self-confidence!" Kate lay still on the floor and wet towels, blinking happily, loath to move. She nodded and blushed a little, "I'm very happy for the great progress that my son is making. I spent all this time teaching him everything I know... " "I know," Dr. Wood smiled, "Erik is a lucky boy because he got to learn a lot from his horny mother. Erik, you have to be grateful that your mom has been so helpful to you." "Of course, I am grateful to my mom for a lot. I strive to be the best possible... And I did my best," Erik said. "Yes, that you did." Dr. Wood confirmed. "Kate, you have to admit that Erik was very good and afforded you many, many beautiful and powerful orgasms." "Yes, I admit," Kate said, blushing, "I have to be honest... The sex with Erik was so amazing! Ever since he fucked me the first time my libido has suddenly been in overdrive. The more sex I have, the more sex I wanted." "I see, you are addicted to his big cock! Our young stud sparked the big flame of lust in you. And since then, you've been constantly in a state of arousal. But, I think he has only revealed your true nature, darling. And... obviously, both of you are insatiable!" Dr. Wood whispered and continued, "However, we need to talk about the next phase, about Erik fucking other women." Dr. Wood paused and glanced at Erik and his mom. Erik was waiting for it eagerly. The thought of fucking another woman besides his mom made him very excited. But Kate was not sure if she was comfortable with Erik fucking other women. Dr. Wood noticed this, too. "Do you agree with it, Kate?" Dr. Wood asked her softly. "Yes, but I am slightly disturbed... I'm not sure... these women...I don't want Erik to catch anything." "Ooohhh darling, don't worry!" Dr. Wood said, relieved when she realized that Kate was not truly jealous. "The good thing is that they've all got medical checks and have got no STD's." Kate nodded and Dr. Wood continued. "I have a number of women a little younger or older than you, who also come to see me with their sexual problems. Would you like to help me in selecting the women for your son?" "Yes, of course!" Kate said. Now it was clear that it excited her. "I have a question, Kate. Err... how do I say this... The selection of the right woman for Erik would be easier for me... if I checked him... You understand?" Dr. Wood tried to explain. Her voice became official sounding again, but Kate could see a sparkle in the good doctor's eyes. "You want Erik to fuck you first," Kate asked bluntly. She was instantly turned on by the thought of watching her son fuck the doctor. "Yes...if you agree. I need to know how quickly he adjusts to another woman... so I know what kind of woman he needs... older, younger, more experienced, voluptuous... " "Sure! I understand it, Dr. Wood," Kate said brightly. "In this way you'll be able to choose a woman for him more easily. She now turned to her son and softly asked: "Erik, would you like to fuck Dr. Wood?" Kate asked softly. Erik couldn't quite believe his ears. His mom had jus offered him to fuck their doctor, right now. He accepted enthusiastically. "Yes, yes, of course!" "OK, I'm glad that we both agree," Dr. Wood said happily, meeting his eyes. Then she continued in her official voice. "Please Erik, go to the bathroom and wash your beautiful cock." Shortly after Erik returned, Dr. Wood said. "I want you to show me everything you've learned. At first, be gentle, do it slowly, and then fuck me harder and harder." Erik nodded. He was scared, excited, and nervous as hell, all at the same time. Then Dr. Wood started to undress slowly. Although she tried to look serious and professional, Kate noticed that the doctor's body was twitching in anticipation. Eric's cock jumped as he watched Dr. Wood's clothing fall to the floor, piece by piece. The doctor unhooked her bra and slowly peeled it off, revealing her bare rounded breasts. Her breasts were also fairly large, but compared to his mom they were somewhat smaller and saggier. Her stomach had a little weight. Then Dr. Wood took off her panties. Her ass was very big. When she turned around Erik could see the most attractive and amazing part of her body: the big, thick, dark area between her legs. Unlike his mom, Dr. Wood's pussy was covered in thick, curly, black hair that reached about 2/3rd of the way to her hips on both sides. Dr. Wood noticed that he was staring at her pussy with great attention. "Erik, you must know, each pussy is different with every single female based on thickness, colour, curly or straight haired, length, size, smell and covered area." "Yes honey, each pussy is different. Dr. Wood has got a really nice thick bush of pussy hair! Enjoy it," Kate confirmed and added, "And don't forget to check if Dr. Wood's pussy is ready." Erik nodded as his hand was going down to the doctor's vagina. He slowly massaged her hairy cunt preparing her. He had never felt a hairy pussy before, so he was surprised at how soft, warm and wet it felt. By now, her pussy was completely soaked and he could smell the musky scent of her pussy juice. He loved to fuck his mom, but the smell of Dr. Wood's moist pussy unleashed Erik's animal instinct. It awakened in him something new. It was a strong desire for other women. He gently pushed Dr. Wood down and she obediently lay back on the towels and peered up at him. Erik got on the floor between Dr. Wood's legs and Kate watched as Erik kissed and licked the doctor's neck, breasts and tummy. He was attentive and patient with the doctor and his mom was so proud of him. Then he began licking Dr. Wood's pussy and her nice hard clit. "Ohhh mmmm I've waited a long time for this. Please Erik, suck me and eat me the way you want to and show me how good you are!" Dr. Wood moaned appreciatively. Erik's Transformation Ch. 06 Erik licked her slowly and firmly. He plunged his tongue into her wet pussy and then thrust in and out like it's a cock. Dr. Wood moaned in ecstasy, thrusting her crotch toward his mouth. Then he slid two fingers in and started massaging her G-spot, and slowly started to lick her clit up and down, then side to side, then round and round. It was incredible and made her so damned horny. "Aaaahhhh," Dr. Wood gasped, biting her lip, letting her eyes close in pleasure. "Give me more. Put your other finger in, please..." He started to work a third finger into her hungry pussy and he noted immediately that it was wider than his mother's. "Honey, Dr. Wood loves having her pussy stretched wide. So slide on up and shove your fat cock inside of her. She needs that!" Kate said. "Oh yes. That's what I need!" Dr. Wood whispered her eyes wide. "I love having my pussy filled with a fat, hard cock. Hurry up, Erik. I need it bad. Give me your fat cock, please!" Her voice was not professional, now. She had transformed from a serious doctor into a horny bitch. She raised her legs and placed her feet on Erik's shoulders. Erik remembered how she told him about what women like and what to take into account when fucking his mom, and he practiced it now. He slid just his cock-head down and stopped, teasing her. Dr. Wood moaned, pulled him to her and simultaneously lifted her hips, pushing her pussy at his raging cock. "Ooohh please, fuck me!" she begged. Slowly she humped her hips and in doing so started fucking herself on to his cock. Kate moved to the sofa and watched them intently as her son slowly slid his monster cock inside the doctor. He got it about half inside the doctor's pussy. "Honey, swivel your hips in a circle so the doctor can feel your cock from all angles," Kate suggested. Erik did it. He circled his cock inside the doctor's wet hole, without thrusting in and out, playing inside her. It produced a whole range of sensations in her. Kate could tell that Dr. Wood was about to have her first orgasm by the way she was moaning. "Fuck her, Erik. Fuck her hard!" Kate ordered. Seeing them together and watching Dr. Wood's reaction to Erik made Kate's pussy sopping wet. Erik slowly pushed until all of his cock was inside her. That was too much for her, and after just a few minutes of fucking Dr. Wood started having her first climax - a powerful, full bodied orgasm! "Ooooh Erik, I can't believe what you're doing! Please do not stop!" Dr. Wood said breathlessly. After a few seconds, he slowly started to pump her pussy again, with half strokes and then full strokes. He picked up the rhythm and started to fuck her harder and harder. As he did, he watched her reactions closely and tried to vary his techniques to see what she liked best. Dr. Wood started moaning more and more, surrendering herself to him completely, despite the warnings clamoring in the back of her head. Then Erik stopped, pulled his cock out and flipped her over and started to pump her doggie style. Dr. Wood accepted it without resistance. She closed her eyes and lowered to her elbows, tilting her hips giving him better access. "Arrrghhh... Unghhhh," she bellowed loudly, sounding like an animal in heat as Erik fucked her fiercely. Her fingers gripped the towel beneath her tightly. His balls were slapping against her swollen clit. The sound of Erik's body slapping against the doctor's ass, and hearing how wet she was just made Kate even hornier. She stood up and moved over to them. Dr. Wood's big tits bounced up and down in rhythm with Erik's strokes and Kate could not resist. She grabbed and squeezed Dr. Wood's tits, mashing them against her chest. She used her thumbs and fingers to pinch and roll her robust nipples, tugging at them. Dr. Wood's body started to shake violently, her hips rocking as she reached a climax, again. Kate got in front of her and started to kiss her passionately as Erik ploughed her cunt. "Yes, honey. Go on, fuck her, the doctor likes it so much," Kate said, urging them on profusely. Erik kept fucking Dr. Wood at an increasingly rapid pace. Each time he went in, she let out a throaty groan, "Ohhh... Oohhhhhh... Hhhhh..." Despite her earlier orgasms, she continued to burn with overwhelming lust. Within only about two minutes, she came again. She absolutely exploded with a juicy wet, squirting orgasm. Hot fluid came up around Erik's cock, on to her vulva and thighs, and then it ran back down her legs. It was a whole body orgasm, and obviously Dr. Wood couldn't control herself. Kate watched as Dr. Wood moaned and gritted her teeth, her face red and sweaty. Erik continued fucking her and Kate could tell Dr. Wood was cumming again and again. She marveled at the way Dr. Wood orgasmed. It lasted about twenty minutes and she concluded that Erik was pounding Dr. Wood into multiple orgasms, just as he did with her. Then Kate noticed Erik was breathing hard. He gasped as he felt the impending need to empty his balls build inside of him. "Where do you want to ejaculate, honey?" Kate asked him softly. "I want it all over your bodies," Erik answered and pulled his cock out, preparing to cum. "Yes I would love that! Shoot your hot cum all over my face and tits. Ooohh, cover me with your jizz, please!" Dr. Wood yelled. She obediently sat down and Kate sat down next to her. "OK bitches, open that mouths wide! I am going to spurt in your mouths and all over your faces," Erik shouted. He then grabbed Dr. Wood's hand, placing it on his engorged cock. She ran her hand up and down over his erection at a quick pace. He was keeping his eyes wide open, as he wanted to see every exciting detail -- to remember it forever. Suddenly his cock exploded. The first blast startled Dr. Wood, hitting her right in the open mouth, as Erik's hot cum covered her flicking tongue. She turned her head and the next spurt hit her cheek. She moaned in satisfaction as the cum kept flowing on to her cheeks, chin, neck and tits. Then Erik quickly redirected his cock, pointing it at his mom. "Yes! Yes! Yeessss!" Kate screamed, encouraging him as she leaned forward to grab his cock and ensure that every milky drop landed upon her. "Shoot it! Cum for me, honey! Shoot your hot cream all over your mom's face and tits! You know how your mommy likes it!" The jets of his semen shooting from the tip of his cock seemed never ending. Just like Dr. Wood, Kate's face and tits were soon covered with her son's hot, creamy jism. When it finally stopped, Kate used her cum covered tongue to lick the end of her son's cock, trying to get any traces of his cum off of it. After savoring his cum in her mouth for about a minute, Kate swallowed all of it. At the same time, Dr. Wood slowly swallowed her share of his sperm, bit by bit. She took some time to swirl her tongue in the lake of cum to fully taste it. "That was delicious Erik! Thank you," she said with a seductive smile. "Now I know why your mom loves your sperm so much!" Then she turned to Kate. "Would you like some more sperm, darling?" Kate nodded and Dr. Wood started collecting sperm from their bodies. "Oh, look at us, darling," Dr. Wood said. "It's as if he's showered us in his sperm." There was a white, sticky, frothy, juicy mess everywhere. All three had come so much that their juices were now soaking the towels underneath. "I can't believe it! He made us both so wild and horny!" Dr. Wood observed as she scooped up a large amount of Erik's sperm and placed her fingers into Kate's mouth. "It's impossible to resist him!" Soon, Kate's mouth was again completely full of her son's cum. By the time she was done swallowing it all, Erik was looking in amazement at his mom's blissfully glowing, ecstatic face. He remembered how the doctor had immediately figured that his mom was a cum fiend. His mom was indeed a nasty slut and he adored how naughty she had become. "You obviously can't quench your thirst for his cum. When Erik would fuck me the next time, I intend to let you eat his cum directly from my pussy," Dr. Wood said lustily. And she then started to kiss Kate passionately, causing her to moan with pleasure. Erik looked completely satisfied as he went to the sofa with a big grin. "Oh, that felts wonderful," he said, panting. He watched in awe as his mother moaned into Dr. Wood's mouth. "Yes," Dr. Wood confirmed interrupting their kiss. "I am very pleased, too. Now I know how much you enjoyed this, Kate. Your son is a wonderful lover. He has a huge cock and he knows how to use it. He fucked me so hard, I think I will not be able to walk properly for a week!" she said, offering Erik a wink, and added "You were amazing, Erik! And your mom and I needed that so much." "Glad I could help." Erik said with a laugh. "Kate, did you enjoy this?" Dr. Wood teased, knowing the answer. "Damn, it was so good! I came so hard!" Kate admitted. "Do you have any idea which women would respond to him? I assume you know more about Erik now." "Yes, you're right. Now I know more about Erik. He was excellent! He was so good that I changed my opinion of him. He does not have to practice with other women ... I want to say he does not have to learn more. He is the perfect lover right now." "Great! I don't want other women," Erik exclaimed. "I want my mom, only her, no one else! Except sometimes you, Dr. Wood." "What?" Kate was confused. "I have concluded that he is ready for the final phase," Dr. Wood added with proud in her voice. "What is the final phase?" Kate asked impatiently. "Final phase is his complete care about you and your needs, Kate. Without my help!" Then she turned to Erik. "Are you ready for this, Erik? Shortly before, your mommy admitted that her libido was in overdrive... that she is addicted to big cock... that she is constantly aroused...Can you satisfy your horny mom regularly?" "Yes, of course. I learned a lot. So, don't worry Dr. Wood. I can take care of my mom and satisfy her regularly," Erik confirmed with delight in his voice.
