I asked to write part 2 since they were taking to long to do it and did not receive any response. As such I decided to write it and post it here, giving credit to HugeErectson. This part is entirely my own work using part one for inspiration. It picks up directly where the first part left off, and makes no sense if you haven't read part 1. It contains incest and unrealistic body part sizes. Please do not comment to say that it is unrealistic- this is a fetish story, its SUPPOSED to be unrealistic). *All characters are eighteen or over* She was still standing by the kitchen counter when I came back in. "how do they fit?" she asked me. "there okay," I said, trying not to get hard by staring at her top. "Good, then maybe you could return the favor. I noticed we are all out of milk, could you run out and get some?" "Sure, I'll go right now," I was relieved that she gave me the opportunity to leave the house; I could feel another hard on starting. I grabbed my coat and headed for the door. The local grocery wasn't to far away, and I needed desperately to cool off. After a fifteen minute walk I was at the store, but when I got to the register I noticed I only had enough money for one gallon of milk. What ever, I thought. I paid and left. Half way home I started thinking about my mom's massive breasts again. The way she was so relaxed, even trying, to show them off. Suddenly I felt a hard on starting. I tried really hard to stop it, but it just kept going. The pouch sown into my shorts quickly filled and It became painful to walk. Five minutes from home I couldn't take it anymore. I walked over to some bushes by the side of the road and pulled down my shorts, then my special boxers. Out sprang my twenty inch cock, veins pulsing with a purple red head. I sat down and started slowly stroking it. I couldn't stop thinking about my mom, her massive mammaries. It was weird, partly because she's my mom, partly because I had never jacked off with my cock so close to my face (it had never been this long before). My cock was over flowing with precum and I had to take off all my clothes just to keep them clean. Since my parents had never gotten me circumcised, and with the precum and all, my cock was making this really slick slapping sound. I was using both my hands and really going for it. Just the thought of my moms tits getting even LARGER. I felt my oversized balls beginning to tighten, and just before I blew my load I had my most brilliant thought ever. It came to my simply because the bottle of the pills I was using said it increase sperm load size. I wanted to see how big my load was, so I stopped my pumping and grabbed the milk carton. I emptied it out on the ground, then positioned my self over it and started to pump me pulsing cock again. After a minute I felt my balls tighten gain just before I blew I put my head in the top of the carton. If the ground hadn't held the carton it would have been blown away. The first thick white creamy rope (and I mean rope, it was like, at least half a centimeter in diameter) of cum spewed out of my cock into the carton and splashed across the bottom, nearly knocking it over. It was followed by another, and another and another as I kept pumping, until the ropes turned into streams and then stopped. I was so dizzy that I fell back as my cock became flaccid. After five minutes of rest I looked at the carton. It was nearly full to the top! I put the cap back on and then removed the sticker on the side. I smiled as the dirty thoughts I had just used came to mind. I quickly cleaned up as best I could and ran home. When I got there my mom was still in the kitchen, making more tops. She was still wearing the one she had on when I left. I sat down at the table and put the milk carton on it. "Hey, I got this new brand of milk for you mom. It's supposed to help women who's breasts are growing larger," I said. As she turned around I tried my hardest to keep a straight face. "Really, of honey that's so sweat! Here, let me try it," she came over and picked up the carton, not even questioning what I told her. For a second I was worried that she might recognize that it was cum, but I didn't think my mom was the kind to give guys head. She poured a glass full, but before she had some she said, "Its warm!" Quickly I thought up a reply, "Oh, well you see I got there just as they had refilled the fridges, so it wasn't that cold to start out, then with the long walk home in this weather..." "Oh, that makes sense, okay," and with that she sipped my cum. "Hmmm... tastes a bit salty, but I kind of like it. Thanks honey," she beamed. I couldn't help it, I was so hard when she said those words. The pouch was full again and I hurt to keep my cock in it. Once my mom finished the glass of cum she smiled at me, then noticed the expression on my face, "whats wrong honey?" "Sorry, its not you, its just well..." I pointed down at my pants. She came over and hugged me, not helping by shoving her breasts in my face, her areolas showing over the top, "Oh my poor baby. Listen, if it helps at all, Ill let you walk around without any pants on. Would that help?" I jumped, "But mom, you will see me and..." "No buts, its nothing I haven't seen before and I won't have my son in pain on my behalf!" She stepped away and looked at me expectantly. Slowly I got up off the stool and slid down my pants and boxers at the same time. Out sprang my monster, and quickly watched her eyes dart to it then back to me. "See? Now doesn't that feel better?" "Yes mom," I said with a smile. "Good, now I'm going to go take some more pills for my breasts and maybe another glass of the milk you gave me." She walked out of the kitchen and went upstairs. The rest of the day was exciting, but my previous jack off shesh helped a lot. That evening it began to storm, badly. I went to bed after taking more of my growth pills. It was 3 in the morning when I heard a voice over the thunder. "Honey?" my mom was standing in my door way, shivering. "What is it?" I asked, still groggy. "The roof is leaking over my bed, I just woke up freezing and soaked!" She walked into my room. In the dim light I could make out that she was wearing one of her bras that she made. I couldn't tell what color it was, but it was a reverse shelf bra. Instead of holding the breasts up and exposing the top of the breasts and nipples like a shelf bra, it came down from the top and stopped just after where I thought her nipples were, leaving the bottoms of her breasts fully exposed. Other than that she had on a standard pair of panties, which I guess she hadn't had time to make like her tops. "Could I sleep in your bed for the rest of the night?" she asked. I groaned, "Sure, I'll go find a sleeping bag and sleep on the floor..." "Oh no honey, my chest my be bigger but I don't take up that much space! Just let me slide in next to you." And with that she walked over and pulled up the blankets. I didn't even get a chance to tell her that I was naked. I slide down as far as I could; knowing the massive hard on sleeping next to my mom was going to give me. I closed my eyes and tried not to think about it and go back to sleep... It must have still been night when I woke up again, because it was still dark. I could tell something was wrong, because my dick felt funny. I opened my eyes and that's when I saw the hottest sight ever! My dick had become rock hard in the night and I must have rolled over after I had positioned myself facing away from my mom, because there was my raging pulsing cock, slightly wedged up in between my moms breasts. They were still wet from the rain and my cock felt so good and warm and wet in between them. Normally (whats normal about this?) I would have just pulled down and turned away, but in my half sleeping stupor I went with my other head. I slowly started humping back and forth in my bed. My moms breasts, although wet, didn't give way much. They were so firm! None the less it felt great and I kept doing it, until I felt my precum start flowing again. That was when I almost stopped. She was still sleeping, all I had to do was pull away and she would never know. Like hell I thought and with that kept going. With the precum I was now gliding nicely between her breasts, and with the downward support of her reverse shelf top my cock was being firmly pumped by her breasts. I was in heaven, and as I pumped my cock into her breasts my head popped out from in between them. I pulled down enough so that it was still in between, I didn't want to wake her. As I did so her nipples slipped out from the bra, which I had pushed up with my dick. I could see them in the dark, and they were pointy and hard. Was it that cold, or was she turned on in her sleep? Either way the sight was too much for me and I blasted thick ropes of cum into her breasts. It took all my strength not to make any sounds as I came. I watched as my cum over flowed from in between her giant breasts and seeped down the side and over the nipple to puddle on her side. She began to stir, and I realized there was not way to explain this, so I did the only thing I could do with so little time. I closed my eyes and did my very best to pretend to be asleep. "Oh my! Honey?" I heard her say. I kept my eyes closed and breathed slowly and rhythmically. "Honey?" she said again. "I guess he must have done it in his sleep. Poor thing." I heard her say, then she got up and went to the bathroom. I awoke the next morning after passing out from the last nights experiences. I looked over and saw that my mom had already left the room. Where she had slept the night before there was only a damp spot, she must have cleaned up the mess. I HAD GOTTEN AWAY with it. I was so happy that I quickly dressed, not putting on pants and went down stairs for breakfast. What awaited me in the kitchen nearly knocked my out. There was my mother, wearing only some jeans and no top! When she heard me coming down the stairs she turn around and smiled. "I figure its only fair for you to be so comfortable if I get to be to. The truth is the reason I wanted to slip out of those tops was to relieve some of the pressure," she said without blushing or being awkward. My cock quickly began to fill so I made a quick move to the stool and tried to act nonchalant, "Its okay mom, your beautiful anyway, so I don't mind," I grinned as I thought of the night before. Now seeing them in full light, they were gorgeous. The nipples were an inch in radius with the tips one centimeter out. They were a nice pink red color. "oh thank you honey. You really think so?" I could see her nipples hardening, was she turned on? "Of course, why would I lie?" I said. She walked around the table to give me a hug. When she got to the stool she saw my massive boner that I had hidden under the table. She stared at it for what seemed like a minute then continued toward me and hugged me. My erect penis went up between us and I wished I had worn no shirt, but that would have been too obvious. "If only all men were like you," she said, "in more ways than one," did I catch a hint of sarcasm in her voice. Did she just make a comment about my penis? I took my opportunity. "Oww, mom, your putting to much pressure on my penis," I said. She quickly backed up, but still had her hands on my shoulders, "oh sorry baby, I didn't know." She giggled, "tell me, do you masturbate to relieve the pressure?" "Eww, mommmmmm!" "Just be honest son, do you," her eyes didn't flinch from my cock. "Well, no," I lied, "ever since I started the pills I stopped. It doesn't feel the same I guess." I tried to act childish and young. It worked, "Ohh, that must be so hard for you. Do you want mommy to help you?" She said in an even voice. I looked into her eyes as she kept hers on my pulsing monster, which was pointing angrily at her tits. "What do you mean?" I said, keeping up the act. "Well I know that it's the pills and hormones of a strong young man that is doing this to you and I just want to help. I know its not me that makes you, ummm... like this and I could help." "Like this," and with that she reached back with her hands and grabbed my cock and started pumping. Her hand felt so soft. "Does that feel better honey," she said, still mesmerized by my penis. "Oh yeah, that feels great," was all I could say. She moved one had to my balls and started fondling them. With her other hand she made smooth pumping motions up and down my penis. It was all I could do to not cum right there, I groaned loudly. "What a big boy you are!" She said in a loving voice. I looked down to see precum leaking steadily down my shaft, lubricating her hands. Now she was pumping even faster, getting some of my precum on her breasts. I continued to groan, until I heard my mom make a faint moan of her own. She was getting turned on. The room filled with wet slapping sounds as she pumped me furiously. We went like this for nearly 15 minutes, until I was getting close to cumming, but I wanted to see what was going to happen next. My mom was using her back to pump my cock, so her tits were juggling up and down with each stroke. I couldn't take it, I grunted and then released. The first rope of cum came out as my mom was pumping up, so it went straight into the air and hit the ceiling, then splashed down on me and my mom, the next rope came out on the down, so it hit my mom directly in the face. She didn't stop pumping as seven more ropes of cum came out hitting everything from the table to her tits. I watched it all, and when it was over I felt amazing. My mom, who's face, breasts, and hair was covered in a thick layer of cum, said, "Honey, could you get me a paper towel?" I quickly got up and got her the roll. She was helpless since she couldn't open her eyes. "Here," I said as I put the roll in her hand. After she wiped most of my cum off her face she looked around, then smiled at me. "Well, how do you feel?" "Relieved," was all I said as I grinned. "Good, I'm going to go clean up, why don't you do the same?' We both went to our separate bathrooms and showered. When I came out of the bathroom and went to my room for some clean clothes I realized that today was laundry day and I had no more shirts, but after everything I didn't care and just went on naked. When I came back downstairs she had cleaned up all of the cum except what was left on the ceiling and was at the sink trying to washed the cum off her jeans, she had put on a new pair. "How does my big man feel?" my mom said as I came up behind her and hugged her. "Amazing, thanks for the help" I said. "Nonsense, what are mothers for? If you ever feel the pressure is to much, just come to me and I'll relieve it, okay?" she said as she turned around and kissed me on the forehead. "okay," I said as I stared at he nipples. "Going around nude now are we?" she smirked as she backed up from the kiss. "Well today's laundry day and that was my last shirt. But yes, besides, its more comfortable." "Good, I'm glad you feel comfortable around me." She smiled, and turned around to continue washing. I got an idea, and went over to the drawer with the measuring tape. "Hold still mom, I want to check something," and with that I slid the tape under her arms and around her breasts. She didn't protest as I checked the numbers. "Wow, almost two inches more! You really are growing." "oh that's great, I'm so glad." She said without turning. The rest of the day was pretty boring. I kept low to the ground, yet tried not to seem awkward. My mom had prepared her bed so it would dry quickly and much to my disappointment she slept in her own room that night. Restless that night, I went online and searched for the brand of pills my mom was taking. Sure enough, they were of the same brand as mine. I read the effects and they were this, breast enlargement, nipple enlargement, firmer breasts, and firmer nipples. On the warning page it said, "Warning, side effects if taken on plan 2 include increased fertility, greater breast sensitivity, increase libido, and in rare cases, breast lactation." I had no idea what plan 2 was, so I went to the instructions and check. It turned out that all their products had 2 ways to be used. Plan one was one pill a day, what my mom was doing and what I had been doing up until 2 days ago was plan one. Plan 2 was to take two or three pills a day for increased effect, but at the cost of possible side effects. For me they were increased fertility, increased sperm load size, and more powerful ejaculations; besides the intended increased libido, size and stiffness. I got all kinds of ideas that night, and went to sleep thinking about tomorrow. When I got up the next morning I had a plan set out in my head. I wasted no time and took two of the pills, then got myself hard (I had gone to the bathroom so my morning wood was gone). Once I was fully erect I went down stairs, my cock leading the way. My mother was still asleep so I sprung into action. I got out the "milk" and pour a nice tall glass. Then I took out three of my mom's pills, four was the maximum daily dose and I figured she would take one when she woke up, and crushed them up and but the powder in the milk. I then mixed it well and made eggs and bacon. I made sure to make the bacon and eggs a little salty, so she would drink all the milk. Then I put it on a tray and went up to her room. She was still asleep, so I went to her bedside and say down. "Mom?" I said a little loudly. She woke up and smiled when she saw the breakfast. "Oh honey, your so sweet. Thank you!" She took the tray and started eating and complemented the cooking. I took out her pill bottle from the bed side stand and took a pill out and said, "Don't forget this," and handed her the pill. "Thank you," and she took the pill and washed it down with some milk. I watched her drink a quarter of the glass of "Milk" in one gulp, then left to not seem weird. Half an hour later she came down with an empty tray. "I get so hungry these days, it must be my growing breasts," she said. I couldn't help but nod because she was wearing only a black, lace thong, and nothing else. I figured that it would take a while for the full effect of the pills to hit her, so I told her I was going out to bike for a while. I left for nearly six hours, long as I dared without worrying her. When I got back she was in the living room reading a book. When she saw me she smiled and went back to her book. I was annoyed until I realized that I was fully clothed and that she had nothing to look at, so I went upstairs and stripped. Then got myself hard, and told myself, "show time." I walked into the living room with an anxious face, and my mom dropped on it with one look. "Do you need my to relieve your penis again?" she said, already closing the book. I walked over and sat down on the couch next to her, cock straight in the air. "Yes please mommy," laying on the innocent. I pulled out a measuring tape, "But first, can you measure me? I figure we could keep track of each others growth." "Sure baby, here, let me see." She kneeled down in between my legs, just like I planned. Her giant breasts, nipples now hard and protruding an inch each, lay on my thighs. As she kneeled down, when her breasts touched my thighs, I caught a quick red flash of her face. Her breasts must be more sensitive, I thought. She took the tape and held one end on my balls and the other at the tip, "Wow, my big man is 21 inches!" She put the tape down and began the pumping. My plan was working flawlessly, with each pump her arms unavoidably grazed her nipples and breasts. With each pass she became more and more short breathed, becoming very rapidly excited. I, trying my best to seem unaware, began to slowly hump her hands, and in doing so, added to the friction on her breasts. A Growing Anticipation - Continued This went on for ten minutes, I didn't cum so fast this time because I had prepared myself mentally, and because the sensitivity of my mom's breasts stopped her from going too fast. Since I was more calm, precum didn't come out, so I made my move and choose my words carefully. "Hey mom, maybe if you were to lube my penis, this would go faster," I said. She looked around, her face red from her excretions as well as her excitement, sweating, and panting from excitement and continuing to pump, "Okay, honey, I think there is some soap we could use in the..." "No," I groaned, "Don't stop, whatever you do, don't stop." She smiled at the way I needed her so bad, "Okay, how about this," she said as leaned forward to spit on my cock. As she was so short, she barly got her mouth over my cock head, and as she opened her mouth to spit I thrust up, and with that she took the head of my penis into her mouth. I could tell she was surprised, but I closed my eyes and pretended to be unaware of what I did. She, not wanting to seem like she had made a mistake, started sucking me. It was so warm and inviting, her tong lapping at the tip. It took all my strength to not cum right there. But I didn't, and it helped that she stopped pumping her hands and put them on the couch to support her head. I groaned as she moaned on my dick, and slowly reached out and grabbed her nipples. She didn't complain, but kept bobbing on my penis. I started pinching them and rubbing them, and massaging her breasts. She moaned more and more and bobbed her head faster and faster, going farther and farther down on me. I was getting close to cumming, but I knew that I had to make her cum to, so I pinched harder on her nipples and as I felt her body shudder I let loose and yelled, "I'm CUMMINGGGGGGG!!!!" I thrust up deep into my mom's mouth as rope after rope of cum spewed into my mom's mouth, forcing her to swallow whether she wanted to or not. After three powerful ropes her head flew back off my cock and more ropes of cum went up into the air and down onto the couch, me and my kneeling mother. After we both caught our breath, me laying back, her, laying her head on my lap, she said, 'So... much... sperm... Ha ha... I'm so full I couldn't eat a bite." We both laughed and went to clean up. After that day I hatched a plan to fuck my mother. For three days I didn't ask her for any more help, even when she offered. I kept on giving her and myself the maximum dose without telling her, and waited as my balls grew larger and larger with cum. Then, on the fourth day, I hatched my plan. My mom was in the kitchen, washing plates, when I came in and asked, "Hey, mom, its so nice out, why don't we go tan by the lake?" "Oh, that sounds wonderful, "just let me slip into a swim suit..." "No mom, in the nude. Besides, no one will see you besides me. No one's around." She hesitated for a moment, then sighed, "Okay, I'll be out in a sec." I went out and set up the towels on the lay back chairs we had behind the house. Then I lay down and waited. Five minute later out came my mom, wearing nothing. This was the first time I saw her pussy, and it made me hard so fast, but I acted as if nothing was going on. Once she got settled in the chair I asked, "Hey, want me to put some lotion on your back?" "Oh your so nice, but I'm fine..." "No, I want to do you a favor after all the help you have given me," I said as I grabbed a bottle of tanning lotion and walked over to her. Her eyes followed the swaying for my penis, as if mesmerized. "okay, honey, if you really want to," she said as she turned over, giving her sensitive nipples a rough rub on the towel draped over the chair. I didn't give her a second to reconsider; I put the lotion on my hands and began rubbing it on her back. I started in the middle, slowly working my way to the sides, until I was rubbing the sides of her breasts. I kept going back and forth over her back, and as often as possible, the sides of her breasts. Soon, I slowly heard her moaning very softly, and I shifted down to her legs. I started at the bottom, but quickly went up to her thighs, until I was centimeters from her pussy. Then, without asking or waiting, I moved to her ass. She didn't stop or complain, but kept softly moaning, as if she were sleeping. I switched between her ass and thighs many times, each time getting closer and closer to her pussy as I passed it, until I was rubbing it on each pass. Then I said, in the softest voice I could do, "Turn over so I can do your front." "I don't know honey" she said even as she turned over without opening her eyes, and as she turned I noticed stains where her nipples had been on the towel. She was lactating. Her face was also red and she was sweating. I started on her belly button, working around in circles, slowly getting closer to her pussy and breasts. Then I slide my hands up the middle of her breasts and around the sides. She moaned a little loader, but didn't move. I kept circling around the breasts, until I was at the nipples. I noticed milk, dripping slowly down the sides of each breast. That's when I decided to strike. Without saying anything, I put on knee in between her knees. She, unconsciously, let it through. At the same time, I started massaging her nipples, which made her breath heavily. I kept moving my knee a little this way and that, until there was space enough, then I put my other knee down. As I massaged her nipples, I slowly used my legs to pry hers apart, until I had enough space. Then I very slowly, as slow as I could, lowered my shaft onto her pussy, letting it slowly rest on top of her. She didn't seem to notice, and I guess if she did then she just thought it was because I had no where else to put my massive penis. Slowly, I began to move back and forth. Just a little at first, but going faster and faster, trying to make sure she didn't catch on. She moaned more, but kept her eyes closed. I kept this up until my precum had drenched both my penis and her pussy. Then I slowly, holding my breath and praying, not stopping my groping, slid my penis all the way back until the head was at her vagina's lips. Quickly, before she could notice, I thrust myself into her. Immediately she gasped and opened her eyes and looked down. "What are you doing!?" she gasped, She stared in amazement for three seconds, during which I pulled out and pumped back in. "wait, stop, son, we can't do this..." her words trailed off as I continued to thrust. Without saying any more she grabbed my shoulders and held on. I pumped deeper and deeper into her, until I hit her womb, which was 8 inches back. Her face was bright red, her oily breasts beading with sweat, going up and down with my thrusts. I bucked and bucked and she wrapped her legs around me and screamed, "YES YES YES, FUCK ME HARD, YEAH BABY, FUCK MOMMY." I was getting closer and closer to cumming, so I leaned forward and kissed passionately on the lips. She stuck her tongue into my mouth and I came inside of her. She moaned and I groaned and then she yelled, "OH MY GOD, SON, I FEEL SO GOOD, I'm CUMMING, I'm CUMMING, FILL ME WITH YOUR SPERM." I poured out all the saved up sperm from the past three days, slowly backing further and further out as she filled up, until the head was forced back and her pussy spewed out cum onto the chair. I kept cumming all over her, until the penis became flaccid. I leaned back and admired my work. My panting mom, was cover completely in cum. Literally all her entire upper body was covered, and more was still coming out of her vagina. Once she regained her breath, she smiled at me, and said, "I'm so happy you did that. I love you so much." I moved forward and lay on top of her, my cum holding us together and kissed her as deeply as I could. We lay like that for ten minutes, arms around each others backs, kissing. Then we went inside and showered together, and lay in bed talking. "I need to be honest son, that day I gave you those two pills, I knew what they would do. I wanted to see you grow." I was a little shocked, as I held her near me on the bed. "I have to be honest to, I've been giving you pills in your milk every morning. That's why your breasts started lactating and became so sensitive." I was nervous she would be angry. She snuggled closer to my, her head on my chest, facing my penis. I could feel her looking at it, "I was wondering about that, and by the way, after the time I... sucked your cock, I knew that the milk wasn't really milk, but I drank it anyway. The truth is, I love the taste. Something about it just makes me crave more." The way she said that made my penis become hard. "Ohhhh... do you like it when mommy talks dirty?" she said, turning her head to face me. "Yes," I said. "You're a naughty, dirty boy," she grinned. She reached over to the bed stand, dragging her massive tits across my chest, and grabbed the measuring tape. She then went down to my hard penis and measured it, "Ohh my naughty boy is 23 inches. Are they all for his mommy?" "Yes," I groaned. Then I pushed her over and went on top of her. I put my massive shaft between her now double G cub breasts and she sucked the head into her warm wet mouth. She pushed her breasts together, creating a sweaty, warm, soft vacuum for my cock. I began tity fucking her and face fucking her, slowly humping her body. I groaned loudly with each thrust and she moaned constantly. As we went faster her face turned red and she flicked her tongue on my cock. Milk spurted in small, thin streams out of each nipple, into the air, with each thrust. Her breasts turned redder and she moaned louder and louder, and breathed heavier and heavier. I put my hands on the bed head board and thrust with all my strength into my mom's hot wet mouth and tits. I began to get that cumming feeling, and decided that this time I should warn her, "I'm going to cum mom, let me go so I can cum on your big tits!" But she just let go of her tits and grabbed my ass, pushing my in and out of her. I yelled, "I'm cumming!!!" and blew a rope of fresh hot cum down my mom's throat. She drank greedily, as if she were a baby on a mothers nipple. This time she was ready for the load, and didn't let a drop seep out. She and I lay panting on the bed for ten minutes, before she came over and made out with me. "You feed me so well, let my feed you know," and she led his head to her nipple. I popped it into my mouth and sucked in the milk that flowed from it. It was sweet, and warm, and the harder I sucked the more she pushed my head into her breast. I switched nipples, kneading the one I had just left with my hand. She moaned more and more, and as she did, I became hard again. She felt my pulsing girth on her thigh, and reached down to pull me into her, but just before I got in I stopped her and said, "Wait, mom... are you on the pill?" My mind raced as I realized I had already cum deep inside her hours before. "Don't worry, I think I read that these pills I'm taking act as birth control," she moaned as she continued to pull my penis. I knew this wasn't true, but that the opposite was true. That meant she either wanted me to get her pregnant, or honestly was mistaken. Either way, I was too horny to care, I thrust my hard cock deep into her vagina, as if it were sucking me in. I bucked and pumped her as fast as I could, feeling the lining of vagina fold around my shaft and head. I pushed harder and harder, both of us making sounds like animals. Then, I felt a small opening, with each thrust, I was sure it was there. About the size of pea, but I could feel it. I realized this was her uterus, and felt the cum rising in my balls. "I'm cumming!" I yelled as pushed the tip of my penis up to the entrance to her uterus. Hot cum forced it's way into her uterus, quickly expanding it, filling it. She screamed. Her womb filled with cum, and then forced her sons penis away from the small opening, into her vagina, which I filled quickly with my cum to. I looked down at her belly, which was visibly bigger from all the cum trapped inside. My cock slipped out now, and continued to spew ropes of steaming cum onto my mother. I was in heaven. We stopped fucking after that day for a week, not because she was having doubts, but because my cock was tired. I called the company that made the pills, and they said that the massive loads of cum had drained my system, and that it need to recharge. So we went around on our normal business. My cock had tapered out at an even 2 feet, and her breasts at a double G cup. Then, on Thursday, I decided my load was ready. I had watched my balls expand each day, and now my sack was the size of a baseball. I was confused on how they could hold so much cum, but then I remembered that there were a whole bunch of other glands in my body that added to it. I was in the bath, which was one of those glass door and wall things, when I called my mother. She came in wearing a shelf bra that almost completely hidden behind her breasts. She was wearing a g string that was just a small strip of material over her vagina and straps around her waste. Her eyes widened as she saw my cock standing poll out of water. Without even waiting to take off her skimpy clothes she got in the tub across from me and closed the door. She reached out and grabbed my purple headed cock, and began to pump. I pulled her legs over my hips until her breasts came around my cock and she moved her hands to the position a if churning butter. I reached down into the clear water and pushed her g string aside and began fingering her. We moaned and her faced turned red from the hot water and the hot sex. I stopped her, "Wait, turn around," and she did. I spread her legs over my face, and luckily tub was only half full so I could breath. I began eating her warm, sweaty, pussy. She moaned and leaned forward onto my cock as we 69'ed. This was so hot, I could feel my balls tighten, so I stuck my fingers forcefully inside her vagina and ass. "Oh my god!!!!" she gasped as her head shot off my cock. My penis came the hardest it ever had. The first rope of creamy white cum hit the top of the glass bathtub roof and cascaded down the walls into the tub. Then another came, and another, each coating everything in the sealed tub with thick layers of cum. My mother turned around my cock and started pumping like she had before. My cock didn;'t stop spewing rope after, its thin splattering sound hidden by the slapping of my moms hands on cock. Eventually the spurts died, and I became soft. I looked around. The water which had originally been clear was now the color of think milk, and me and my mother were both panting hard as we looked at each other covered in cum. What a day. We got a surprise visitor the next day. My sister, only a year older than me, had just gotten of school for break, she was at some weird art school that had its own plans. She was shorter than my mom, only five one, but her long red hair and pale white skin made her seem more mature. Her breasts were only double C cup, but she always wore push up bras that made them look bigger. The first thing she said when she got in the door was, "Roadtrip!!!" She quickly followed up with questions about mom's breast size, which was hood because it distracted her from the hardon's I was getting now that I wore pants again. Apparently she was having a whole bunch of art moved across state for an art gallery she was in, and it would be a lot cheaper and easier to have it shipped here, then driven up state. My mom was skeptical about it all fitting in the minivan, but my sister took one look and waved her off. The art was supposed to arrive in five days. The next morning when I came down the stairs I saw my sister having some cereal. I walked past her and said hello, then went and got an orange juice. As I got it from the fridge it hit me like thunder. I turned around to see my sister finishing the milk left in the bowl. That milk was still my cum!!! And whats more, my mom had crushed up a bunch of the pills and put it in her new favorite drink. My sister looked at me with her big blue eyes and smiled, "What?" "Nothing, you still like cheerios?" I stammered, not knowing if I should tell her. "I love em, I have a bowl every morning, sometimes one as a snack in the afternoon to." I tried to seem as normal as possible, "Oh, okay. Hows the milk?" "It's a bit weird, kinda salty, but I like it," she said as she put the bowl in the sink. "Yeah, mom got this new brand," I said lamely as quickly dodged into the living room. The next four days she had at least one bowl a day, sometimes two. I noticed her breasts filling her shirts more each day, and by the fourth day I could tell she was puching the end of the double D range. Her push up bras no longer hid all of her areolas, but her v cut shirts still kept her decent. On the fifth day a truck arrived with the art, and man there was a lot. My mom and sister just looked at me and I began loading it into the minivan. Most of it was just small sculptures and paintings, but there was this one, big piece painting that was my sisters masterpiece. I loaded all the other pieces in first and filled the middle three seats two of the back ones. Then I walked over to the big painting and just frowned. "Maybe we could put it on top of the car..." my mom said. "NOOOOOO!" my sister yelled, nearly popping out of the bikini top she was wearing. It was yellow with a big button in the front holding the two cups together, and had been big on her when she was still a C cup. Now I could see it straining hard just to hold together. My mother was also wearing a bikini, because the weather had gotten up to 90 degrees. I jumped in, "Maybe if we slide it across the middle into the passenger's seat?" "Anything but out side the car," and with that my sister helped me get into the car. We slid it through the car door and back into the third row of seats, then forward into the passenger seat. We then moved around some of the other art, but quickly found that we only had the drivers seat and the far right third row passenger seat free. My mom said, "Maybe we should do two trips?" Again my sister interrupted, "No, no, that would waste to much time, how about I just sit on bro's lap?" My cock twitched at the idea, but I just said, "Okay, if your comfortable with that." My sister said she was fine, but my mom was skeptical, "Only if you two are sure your comfortable, I'm not stopping every five minutes to give you two a break." We finished packing and at noon we all got in the minivan. I got in first, and then my sister, still in the yellow bikini, came in second and sat on my lap. She wasn't to heavy, and I said I felt fine. I was wearing a loose shirt and a pair of semi long shorts, with no boxers for obvious reasons. "I'm okay bro, you ready mom?" she called forward over the huge painting that hid everything in front of us. My mom called back, not being able to see us, "Yep, you guys good?" "Yeah," my sister said. "Then of we go," my mom started the van and we hit the road. The first half hour was okay, we didn't say much since we were all kind of cramped, but at around 12:30 we hit a rough patch of road, and in all the bouncing my cock began to grow. I hadn't had time to be alone with mom since sis got back, so I was already pretty agitated as is, but I still tried to force it down. Slowly but surly I could feel my head slipping out of my shorts and begin to rise up in between my sisters legs. She didn't notice as she was watching out the window, but as it got taller she felt it touch her inner thigh. All I heard was her gasp loudly, but not so loud that the rumbling road didn't hide it from my mom. She quickly turned her head to me, "When did you get so big?" she whispered. A Growing Anticipation - Continued I whispered back, "Well... you see, I'm on some pills like mom's. I'm so sorry, its just with the road and all..." I was interrupted by a pothole in the road. My sister fell forward and as she did so, my cock shoved its way in between her breasts under the bikini. The added strain of the moment was too much, and the big button of the bikini popped off, flinging her bikini top back into my face. "Sorry," my mom yelled back. My sister leaned back and as she did my cock stayed wedged in between her sweating breasts. "Bro, get it out!" she whispered in exasperation. I reached around her and pulled myself forward, out of her tits, but when I let go my shaft just swung back to rest on top on her breasts. "I can't make it stay back, sorry!!!" I whispered, but she just kept shifting her seat to see if she could find away to keep my cock away from her perky tits. Each time the head of my penis touched her tits, I could tell they were hard. This was exciting her. As she moved I noticed that she was grinding her pussy on the base of my shaft, until I saw sweat drip down her back. She turned again to face me, face bright red on her pale skin, "Okay," she breathed heavily, "Just stay still and it will go away," she said as if it were a fact but more with a voice of hope. She put her hands over her nipples to protect them from my cock, but this gave her no support against the bumping of the van. We hit one of those up and down wavy parts of the road and my sister, unable to use her hands, closed her legs around my shaft to steady herself. I could fell the warmth of her pussy and could tell that it was very wet as she ground it into me. I was having trouble containing myself, I mean, fucking my mom is one thing, but both my mom and sister? As the head of my cock rubbed the front of her breasts some more I made up my mind. My sister's bikini bottom was one of those simple tie at the side things, and she had tied them in a simple, one knot bow on each end. During the whole ride I had kept my hands on her hips, just above the ties. Now, while she was distracted by penis, her face red and panting, I slid my hands down and grabbed the string of each tie, then continued to rest my hands over the knot. With each new bump in the road I pulled a little on each tie, just a very small amount, that she didn't notice with the motion of the car, until finally the loops of the knots were ready to let go. During it had been ten minutes now when my sister said, "Bro, my arms are getting tired," in a shaky voice. My cock had been trying furiously to get into my sisters cleavage, and she had to push her breasts together to stop it. I took a chance, "I could hold them for you, until your arms are strong enough again." She looked at me with pleading eyes and I did my best to give a sincere face. "Okay, but don't rub them, and be gentle," she let her arms drop. I raised mine up and cupped her soft smooth breasts. Her nipples were very hard as I pushed her breasts together slightly. "I'm really sorry sis, I can't control it," I whispered in her ear. "It's okay... I understand," she moaned softly back. "Maybe you could..." I was stopped by another big bump in the road. My sister slid forward and I let her breasts permit my cock head in. Then I felt something wet on my shaft, and looked down to see her bikini bottom had come undone, and knew that those were her pussy lips on my cock. "OHhhh..." my sister said as her pussy slid roughly on the base of my penis. After the bump she reached down and tried to fix her suit. "Here, I'll help," I said as I roughly slid my hands off her nipples. She was having a lot of trouble since the suit had slid down and was being held between us, and because she was so excited. I made it look like I was trying to help, but really was pulling the suit away from her in small nudges. While this was going on my cock head was getting a nice warm and sweaty massage. I began to leak precum into my sisters cleavage. "Rise up, I think I can get it," I said. She slid herself up my shaft, and I conveniently let her suit fall to the floor of the van. It was to cramped for either of us to reach it. "Ohh... just... leave it," was all my sister could moan out. She had put one hand on the car door and one on the box of sculptures to our left. I slid my hands over hers and she interlocked her fingers with mine. I slowly started grinding her ass, sliding my penis up and down. She moaned softly and I let myself groan quietly. I had an idea, "Hey, sis, maybe if you... hold my penis away from you breasts it will go down." She didn't respond, but took her hands away from mine and slid them into her cleavage. I felt them grab my cock and pull it out and hold it in front of her. I continued the grinding motion, moving my hands to her waist again. She was trying to keep her hands still, but with the motion of the car she was actually slowly jacking me off. I started to slowly slid my right had towards her vagina. Only a little each time the car bumped. Her body was smooth with sweat and it was easy, until I was just above it. I waited, grinding and fucking her hands, both of us moaning quietly. Her face was bright red now. The car lurched on a medium sized bump, but it was enough that I drove my hand down into her pussy. She squeaked as I stuck my middle finger into her. All bets were off as I began to pump her wet pussy. She looked back at me and we stared at each other. She didn't try to stop me or say anything, but just breathed heavily into my face. Then, slowly, biting her lip, she began to pump my wet cock. I stopped grinding her and she moved her hands faster. A low slapping sound came over the sound of the engine. I was getting close, so I said, "Sis, I'm getting close... Put my penis in your mouth or else mom will see all the cum, and it will ruin your art." She paused the pumping for a moment, then leaned forward and I felt something warm and smooth envelope my cock head. She didn't suck or bob, so I started humping her mouth. Slowly she began to counter the thrust with her head until she was properly blowing me. I stuck another finger into her and began furiously pushing in and out of vagina. She moaned a bit louder and then I felt her pussy squeeze my fingers. It was too much, and I blew my load in her mouth. Ropes of cum shot into her mouth and she was forced to swallow. She missed some, which dripped to the floor of the van. We sat there catching out breath. The rest of the ride was uneventful. When we arrived at the hotel my sister quickly slipped on her suit and ran up to the room before my mom saw her. When me and my mom came up she was wearing a bathrobe. She took her suit case and went into the bathroom to shower off my precum from her tits. My mom said she was going out to do some errands and visit a friend for dinner. It was already 5 and she said she would be back late and to watch a movie in the room and order room service. She took off after deeply kissing my goodbye. I ordered room service and it arrived fifteen minutes later. My sister, who takes the longest showers in the world, was still in the bathroom. I took out the food that was hers, I knew what she liked, and quickly stuffed some of my mom's pills in it just as my sister came out of the bathroom. "Thanks for ordering for me, where's mom," she said as she came over and sat on the bed next to me and began eating. She was wearing only a towel over her hair and bigger one wrapped around her breasts. It went down to her thighs, the view gave my cock a jolt. "She went out to visit a friend, she said to watch a movie and that she would be back late." I threw her the remote. "Okay, I'll look for a movie," she said. She found one we both hadn't seen and pressed play. The room had two beds so I was on one and she was on the other. "Hey bro, is it difficult having a penis that big?" she said. "Oh, yeah sorry about what happened in the car. I'll make it up to you. How about I give you a massage as gift back?" I said. "It's okay, I understand. Are you any good at massages?" she asked skeptically. "The best, just ask mom," I grinned. She turned onto her front and waved me over. I got off my bed and went over to hers. I straddled her back and began rubbing her shoulders. "How's that?" I asked. "Actually feels pretty good," she said, not turning her head from the tv at the end of the bed. I continued on her shoulders and neck for a while, then said, "Want to untie the towel so I can do your lower back?" "I don't know," she said. "Its not anything I haven't seen already, and besides, I'm doing this to make up for the ride here." "Alright then," she reached around her side and undid the knot on her left breast. I grabbed the towel and unwrapped my sister. I admired her firm, pale white ass before I began rubbing her back. We watch the movie as I gave her a through massage for another half hour. She was really engrossed in it when I switched to her leg that she didn't even notice when I spread them. I worked her calf's as I admired her pussy right in front of me. It was pink and looked so good. My dick became erect, but she didn't see it. I decided now was the time. I removed my pants and slid my dick right up to her vagina, but didn't touch it. I had already spread her legs at 30 degree angle, so all I had to do was put my hands on each side of her. She didn't notice as she watched the movie. Once I was in the perfect position, I said a prayer, then thrust forwards as hard as I could. Her pussy was still a little wet from the shower and Oh so warm. I got six inches in as she shot her back up and turned her head wide eyed to face me. "What..." was all she could say before I pulled out and shoved myself back in. She bit her lip and closed her eyes and I thrust more and more of myself into her. I was fucking my sister. I kept a slow, continuous thrusting motion, each time sinking eight inches into my sisters warm pussy. She began to moan and put her hand on the back of my head. I groaned with each wonderful thrust going faster and faster. "Oh fuck, oh fuck, OH FUCK" she said as she came. I was getting close myself, so leaned forward and said, "I love you sis." "I love you to bro," we kissed and I stuck my tongue in her mouth as I came deep inside her pussy. She quickly filled up and the head of my cock popped out and slid up in between her ass cheeks which I covered with more cum, spurting onto her back. We lay there panting for a while, then she said, "Oh crap, I'm not on the pill." She looked at me with a worried expression, and that's when I knew I was going to do what I did to mon, to her. "Don't worry, the pills I'm on cause infertility, just ask mom. But if your worried," all went over to mom's bag and pulled out some of her pills, "You can take these for a while." I gave two pills and she swallowed them without asking. By the end of that summer they were both showing signs of being pregnant.
