Kyra almost laughed out loud at the puzzled look on his face. "So...that's not all I noticed." "What are you talking about?" Kyra let her eyes drop to his crotch. "You were getting hard." Kevin quickly answered, "I was NOT." Kyra began walking towards him. "Kevin, how many times have I been around you when you were hard? I think I know when you're hard and when you're not. Especially in that bathing suit." She was in front of him now, putting her hand on his suit. "Especially when the suit is a little wet. And it clings to your big, thick cock." Kyra wrapped her fingers around him, proud of the fact he was already responding to her. Kevin could not look his gorgeous eighteen year old sister in the eye. Instead, he looked down at the perfectly formed breasts bulging out of her tiny bikini. Her skin was dark tan and silky smooth and... "Did you like it when Mom lay on her stomach and took off her top? Did you notice how you could still see her breasts flattened against the towel from the sides?" She knew he did. He knew he did. And now the hardening cock inside his trunks, which she held tighter and tighter, gave away the answer. "Kyra...," he began to say. "Was it her cute ass that made you hard?" Kyra persisted. "Did you want to put your hands inside her suit and squeeze her ass?" "No!" he managed to respond. But everything she was saying was true, like she could read his mind. She could ALWAYS read his mind. It had been that way from as early as Kevin could remember. It was that way when she first let him see her in her underwear. And then when she let him see her in the shower. And then when she let him touch her. They'd privately been having sex...great sex...ever since. "I don't know," Kyra said with a sly grin. "You seemed to be getting pretty hard then and you certainly are now, just talking about it." The beautiful, young girl's hand was stroking him faster. "Is she my competition?" Kyra asked. "Do you want to fuck her?" "God. She's my fucking mother. I mean, she's my mother," Kevin said anxiously. "And I'm your sister. You fuck ME." Kevin was fully erect. His cock ached from pressing against the front of his bathing suit. It throbbed inside his sister's hand. Lust took over and he put his hands on the outside of Kyra's breasts, letting their fullness fill his palms. Kyra looked at him and said softly, "Maybe you want her to suck your cock." Before Kevin could respond, his trunks were being pulled down and Kyra was kneeling in front of him. Kevin's cock sprung free and pointed up like a pole just inches from her face. As often as Kyra had seen, and tasted, and felt his cock inside her, she never grew tired of it. Kevin lived for this. No matter how many other girls he dated, or how good they were in bed, nothing compared to Kyra. Once again, he was about to find out why. "I want you to pretend this is Mom's tongue and Mom's mouth," Kyra instructed her twin brother. She didn't expect him to actually do it, so it would have surprised her to know Kevin was thinking about the beach. His mother was topless. Her still-firm breasts rose from her body as she lay on her back. He was straddling her body, placing his cock in her mouth. Kyra began the slow, steady licking of the bottom of his cock that he loved so much. She started at his balls and moved up to the tip, never actually taking the cock between her lips. Just licking it. Caressing it with her tongue. She did this several times and Kevin's cock twitched with satisfaction. Finally, she opened her mouth and took in half of the shaft. Then she moved forward and leisurely let it slide in until her lips hit Kevin's hairy body. She pulled back just as slowly. When the tip began to reappear, it was time to get serious. Kyra commenced a methodical sucking of her brother's cock that very few eighteen year old girls could replicate. But in Kevin's mind, it was his Mom. He was fucking his Mom's mouth. "Can you see her? Topless on the beach sucking your hard cock?" Kyra asked while taking a short break. "Yes," Kevin acknowledged, giving in to the fact he could think this way about his mother. "Good. Because she's not going to stop until you cum." Kyra picked up the pace and used her hand to stroke the base of Kevin's cock. She knew this wouldn't take long. She had to think about how to take his cum. What mood was she in today? Oral? Facial? On her tits? Kevin only had to think of one thing. Fucking his mother's mouth and cumming like a madman. Well, he DID sneak in a thought or two of her naked breasts bouncing up and down; of her pussy awaiting his throbbing cock; of her ass accepting all the cum he could pour on it. Then it started. Kevin felt it in his balls. He felt it rush through his entire body. "Yes! Yesssss!" Kyra sucked harder. She moaned with glee. And just when she sensed the first blast of cum erupting from her brother's cock, she pointed it at her breasts. Only a few seconds passed before the first long blast of white cum spurted across her chest. Kevin grunted with each successive blast. Behind closed eyes he saw his cum splashing against his mother's face, dripping down her chin and onto her large tits. Kyra smiled with satisfaction knowing that she had helped him to one of the strongest orgasms she could remember him having. When Kevin opened his eyes he was stunned at the sight. Cum was splattered on portions of Kyra's bikini top. More cum streamed down her breasts, disappearing inside her top. "I think I need a shower," Kyra said, looking down at the 'mess'. "Come on. You can help." She took her brother's hand and led him to the bathroom. *** Amanda Robertson was a successful real estate agent. So was her husband Dan. They made a good team. He was tall, dark and handsome. She was stunningly adorable. When you looked at Amanda you didn't think Victoria's Secret model. You thought homecoming queen. You thought, "I want to fuck this woman. Now!" At 38, she looked almost as good as...well, her daughter. She had shaggy blonde hair that looked appropriately mussed at all times--like she had just fucked a potential million dollar buyer for an hour. It was a look she didn't need a hairdresser for, if truth be known. She was in shape, and not just from frequent hour-long fucks. She worked at it. From her sculptured shoulders to her firm breasts to her tiny waist to her magnificent legs, she was in shape. And showing it off was never a problem for her. This holiday—a week-long stay in the Bahamas—offered plenty of opportunities to display herself. She was in heaven. Amanda and Dan brought the kids this time. Kyra and Kevin were twins, the couple's only children. Kyra was a spoiled, spitting image of her mother. Kevin was a little more reserved, allowing the other members of the family to grab the attention. But, at eighteen, they were able to entertain themselves on these trips, which pleased the partying parents. If the parents only knew. *** The family had connecting bedrooms in a small suite of their Nassau resort. Kyra and Kevin would have preferred a little more privacy, but it would do for a week. And the connecting door locked. They all agreed to meet for dinner at six. The women were lovely, as usual, in their similarly styled sundresses. Spaghetti straps, swooping necklines and frilly hems never looked bad on the tall ladies. Tonight, with both of them obviously braless, men would have trouble deciding who to stare at. "Are we all going back to the beach in the morning?" Amanda asked while the salads were served. Kevin felt Kyra surreptitiously kick him in the shin. "Sure," he answered, followed by a swift, evil stare in his sister's direction. "That would be great," Kyra said with just a little too much enthusiasm. "Maybe we can find someplace a little more private." She looked at Kevin and grinned. "Well, this is Nassau," Amanda said, using her fork to push an onion to the side of her plate. "Privacy is at a premium." "Too bad," Kyra sighed. Her mind was hard at work for the remainder of the meal. When they returned to their room to change, Amanda wasted no time in pursuing the theme of the day. "So did you get a good look? You should have been able to catch a nipple or two when she reached for something," Amanda said. "Will you stop already," Kevin moaned, stripping off his shirt. "I'm not as...as...HOT for her as you think." "Well, did you?" Amanda asked nonchalantly. "Yes." Amanda broke into thunderous laughter. When she was done, she said, "I have plans for you, brother. Big plans." The entire family was on the beach—a slightly more secluded beach on the advice of the resort concierge—by late morning. The sun was high and hot without a cloud in the sky. Amanda and Kyra sported new, but equally revealing, bikinis. Dan and Kevin would have had plenty to look at, even without the occasional beauty that walked passed in the surf. At one point, Kyra and her father walked to a nearby bar, leaving Kevin and Amanda alone on their towels. "Are you having a good time?" Amanda asked. "Sure. I'm glad you let us come." Kevin looked over at his Mom. She was on her back. She had untied the top of her bikini to let it ride low on her breasts. She noticed his glance and felt a tinge of shame at the delight it gave her. "Your father and Kyra are going to some show or something tonight. It'll just be us. Is there anything you want to do?" "Not really. You know this place better than me. You decide." The whole time he spoke Kevin could feel the excitement building inside him. What had happened that his own mother could stimulate him like this? "I'll have to think about it," Amanda answered. She was reaching for the suntan lotion. Kevin watched her place a small amount on her hand and then rub it over her bare shoulders and arms. She poured a little more directly onto her chest, above her breasts. He couldn't take his eyes off her. Does she know I'm still watching? She spread the lotion around, at first avoiding her breasts. Then her hand moved lower. Her lotion-covered palm glided over the exposed portions of her breasts. Her hand hit the top of her bikini, pushing it even lower so that only her nipples were covered. Kevin watched his mother's full breasts roll back and forth under her hand. He felt his erection growing as her fingers moved between her breasts, into her cleavage, and out again. God, you're driving me crazy. Then she put more lotion in the hand and spread it over her flat abdomen. When she got to her bikini bottom she let her fingers slide inside just a bit. Another inch or two and she'll touch her clit. Suddenly, Amanda was rolling onto her side facing Kevin. He looked out at the ocean as fast as he could. "Can you do my back, hon?" his mother was asking. Kevin looked back over just in time to see her rolling onto her stomach, removing the hand that had held the bikini top in place. Only the top was still in her hand and she was placing it at her side. Kevin stared momentarily at her bare back. "Uh, yeah. Sure," he said. When he began to move off his blanket he became fully aware of the extent of his erection. It pressed against the front of his trunks, just as it had yesterday afternoon on the beach and just as it had when Kyra touched him. He moved behind his mother as fast as he could in an attempt to escape her view. He picked up the suntan lotion and put some on his hand. He didn't straddle his mother. That didn't seem right. He just kneeled beside her and moved closer. Kevin touched her shoulder lightly; afraid the lotion would be cold. But Amanda said nothing. Her head was turned to one side, the side Kevin was on. She used her hands as a pillow. Kevin spread the lotion over the top of her back. Her skin was warm and smooth, just like Kyra's. He widened his movements to make sure he got her entire back. That's when his hand accidentally made contact with the edge of her breast on the side away from him. Kevin's hand jerked away and he almost said something. But he kept going. He added a little more lotion and got to the top of her bikini bottom. Kyra WAS right. He DID want to touch her ass. It was full and round, but not the least bit fat. He stared until realizing he wasn't spreading the lotion any more. "Do my legs, please," Amanda said casually. Gladly. It only took Kevin a couple swipes up and down his mother's calves to realize he couldn't continue for long. By the time he got to her ass, having spread the lotion over the inside of both thighs, he had to stop before yanking off the remaining piece of her bikini and plunging his cock into her. His mother, for Christ's sake. "Thanks, Kev. That's your job for the rest of the week." Shit. Kevin headed for the water, glad that the beach was pretty much deserted. He assumed anybody within a quarter mile could now see the signs of his erection. But a couple minutes in the water brought him back to 'normalcy' and, eventually, he was back on the beach again. Kyra and her Dad soon arrived, giving Kevin one more fabulous body to stare at. His sister had a mischievous grin and Kevin suggested they swim, for the sole purpose of asking her what was up. Once in the water, Kyra asked, "So. How was your free time with Mom?" "OK. Nothing special." Kyra came closer. "Are you glad I found a way to get you two alone?" "Kyra, I'm not sure what you think is going on, but an evening alone with my Mom is not number one of my 'favorite things to do' list." He could only hope the outright lie wasn't too obvious. "Whatever." Kyra let her body brush against her brother's. She touched the front of his suit under the water. "What did you guys do just now?" "Lay around." "Mom had her top off again. Did you help?" Kyra said, stroking Kevin's cock slowly. "I helped with suntan lotion," Kevin said, wincing and trying to turn away from her. Kyra followed his every move. "Was it fun?" Kevin didn't answer, but the look on his face indicated he was tiring of the questioning. "Oh, I think it was. You're thinking about it and you're already getting hard." Kyra's use of her brother's cock as a barometer of his thoughts was increasingly unnerving. "I'm getting hard because you're rubbing my fucking cock." "Tonight I want you to really let her know how much you want her," Kyra said seriously. "Maybe even touch her. Kiss her. Lick her nipples." Kevin turned, dove into the water, and swam away. Kyra's laughter could be heard by Kevin even under the water. *** Walking back to the resort, Kyra asked her Mom," So, what are the big plans for you and Kevin tonight?" "I thought we'd hit the casino," Amanda replied, looking over at Kevin for approval. He shrugged. "Sure. I'll need a loan." Amanda laughed. "No problem. I expected that. What DO you spend your money on?" "Things," was all Kevin would say. His mind was still back on what the casino would be like, at night, in a place like Nassau. When he knocked on the door to his parents' room at the designated time, he didn't anticipate what he saw next. His mother opened the door, wearing a dress that made the one she wore the previous night look like a rag. Kevin walked in. "Wow. You look...nice." His eyes quickly followed the straps of the dress to his mother's ample cleavage. From there the dress tightened around her waist and flared slightly below her hips. It stopped well above her knees. "Thank you, Kevin. I wanted to look good for you on our date." Amanda pinched him in the arm as she walked past. He couldn't help watching her ass sway back and forth under the dress. Her hair was neatly styled, as opposed to the wind blown look he was getting used to on the beach, and he caught a hint of her expensive perfume. God. What have I gotten myself into? Amanda Robertson was used to meeting new people without her husband around. It was a part of her job. It actually was a part of her job she LOVED. She could flat out flirt. She was excited about the evening in the casino, and all the prospects it presented for major flirting. Plus...there was Kevin. He had taken an increased interest in her lately, she thought. She had noticed his erection on a couple of occasions already on the trip. The one earlier in the day when he was applying the lotion had affected her to the point where, if he had come any closer to touching her clit while attending to her legs, she would have jumped him. Now Kyra and Dan had given her this opportunity to spend time with him. Alone. She had chosen her dress carefully. Time would tell if her choice was correct, but early indications were that it was. A tingle ran through her like a current. Amanda handed her son two hundred dollars. "Here. Spend it wisely." Kevin was taken aback by the amount of cash in his hand. "Wow! Thanks, Mom. I'll repay you if I win." "We'll talk about it," Amanda said. She kissed Kevin on the cheek. "Let's go." *** Kevin felt a strange sense of pride while walking into the huge, lavish casino with a woman as beautiful as his mother. Immediately he began noticing the stares she got from the men...and the occasional woman. She HAD to notice it, too. Did it bother her? He'd have to ask her some day. They walked around for a few minutes to get their bearings. "I'm going to play craps for a little bit," Amanda finally announced. "Can I watch?" Kevin asked. "Of course." Amanda had always found craps the most enjoyable game because of its social nature. Everybody was affected by every roll; you stood in close proximity to each other; and, congratulations or condolences were commonplace, usually associated with a hug or high five. Amanda worked her way to the edge of the table with Kevin a couple steps behind her and to the side—just observing. He observed his mother and he observed the men ogling his mother. Each time she leaned over the table more eyes looked in her direction. Even before she started winning men were attempting to strike up conversations. Amanda played along without directing too much of her attention to any one man. As her chip count grew, so did the crowd around Amanda. Kevin inched towards her to stay within reach. He saw her push what seemed to him to be a large stack of chips onto the table. Then she yelled instructions to the woman with the dice, none of it making any sense to Kevin. The noise was deafening by the time the dice hit the end of the table. Then all hell broke loose. Amanda's arms were up in the air and she was hopping up and down in her tiny space. She whirled around and threw her arms around Kevin's neck. "Yes! Yes, Kev. We did it!" she said. All Kevin knew was that her breasts were pressed against his chest and it felt fabulous. He put his arms around her and smiled. He didn't want to let her go, but she pulled away and watched as her chip count increased dramatically. He watched her jump a couple more times, her little dress barely restraining her bouncing breasts. He hoped she won more often, but not for the same reasons Amanda did. She gathered up her chips and they backed away from the table to the cheers of many bystanders. "Well, THAT was worth it," Amanda said with excitement. "Yeah. How much did you get?" "Probably close to a couple hundred," Amanda said. "We'll find out when I cash in." She put her arm around his waist and pressed her body up against his. It was a very natural movement which Kevin returned with ease. His hand was on her hip. Don't do it. Don't put your hand on her ass. Don't do it. He was relieved when his Mom removed her arm from around him and he could do the same. It was WAY too tempting. The Twins' Obsession Ch. 02 "You first," Kevin said. "Then if you beg hard enough maybe I'll tell you about me and Mom." Eighteen year old Kyra Robertson lay on top of her twin brother in a Bahamas resort bedroom. She was dressed, having just returned from an evening out with her Dad. Kevin was in his boxers, having just spent an evening with his Mom culminating in fabulous sex on the couch of his parents' attached suite. "Well, OK," Kyra conceded. She rolled onto her side facing her brother. She noticed him glancing down at the ample breasts nearly tumbling out of her low-cut sundress. They were frequent lovers, so Kyra did nothing to conceal her exposed tits. "It was soooo cool," she began. "I didn't start out with the intent of doing anything with him, but the more I kept thinking about you and Mom..." *** Kyra had arranged to spend a long evening with her father in order to give her brother and mother an opportunity to be together. She suspected, rightfully, that Kevin was sexually attracted to their Mom, a gorgeous woman in her late thirties. So she went on a 'date' with her Dad to leave them alone. Kyra's first hint of anything unusual about her date with Dan, her father, was during dinner. She was used to men admiring her young body, flowing blonde hair and stunning eyes. But her Dad? His eyes were constantly moving down to her chest as they ate, devouring the abundant cleavage revealed by her dress. Kyra also noticed the attention she received from him when the family was on the beach the past couple days. She wore a stylishly small bikini that hid little. And Dan did little to hide his attraction to his daughter's body. Nothing had been said. Until now. "Your tan is really starting to show," Dan said to Kyra. "By the end of the week you'll look like you live down here." "I BETTER be getting tan," Kyra said. "I'm out all day." "And that suit of yours doesn't cover much," her father said with a hint of mockery. "Then quit looking at me in my bikini," she said, putting a forkful of salad in her mouth. Kyra playfully pulled the empty fork out, keeping her lips wrapped tightly around it the entire time. Then she slowly licked her lips from one side to the other, top and bottom. "Stop it," Dan said. "What?" "You know what. You're such a flirt." The rest of the meal was uneventful, but the connection between father and daughter had been made and their thoughts would not stray far from each other the entire evening. Kyra would decide whether they took it to the next level and her mind had already been made up. Leaving the restaurant, Kyra held her father's arm like she would a close boyfriend. They were rarely not in contact with each other in some way as they walked from shop to shop on the way to the show. They had time to kill and money to spend, so Kyra didn't let very many shops pass by without entering them. One store in particular was extremely crowded. That was always a sign to Kyra that either the prices were right or the clothing was cool...or both. She took her father's hand and drug him inside. Dan Robertson was a tall, dark and handsome real estate agent. He teamed with his wife, Amanda, to make one of the most successful real estate pairings in the state. They both used their looks to their advantage if it helped seal a deal. Now he found himself in the middle of a crowded woman's clothing store with a mob of vacationing women of every age. And although there weren't many ugly ones, he decided he was with the most gorgeous. He followed Kyra around like a puppy as she flitted from one rack to the next. She'd hold something up in front of her and ask his opinion. Dan, of course, liked everything she chose and let his imagination run wild with imagery of the clothing on his beautiful daughter. Neither would be able to tell you when their attraction to each other reached critical mass. It may have been building for years, weeks or days. But both father and daughter could feel it. Soon, Kyra and Dan found themselves in the farthest corner of the store. Kyra had a top and a pair of jeans on her arm that she wanted to try on. She looked around for the dressing rooms and, amid the crowd at the back of the store, found them. Back home, she would have expected more stringent security leading into the area. Here, customers were pretty much free to come and go in the dressing area as they saw fit. "Wait here," Kyra told her Dad. "I'll be right back." Dan agreed, having absolutely nowhere else to go other than outside. But he was beginning to like the view inside the crowded shop. It was only a minute later that Kyra stuck her head around the corner, caught her father's eye, and motioned for him to join her. He was confused, thinking she needed help with something. "Come here," she said quietly. She turned back towards the dressing rooms, looked over her shoulder to make sure Dan was still there, and walked into the darkened recesses of the store. He followed, further puzzled. The narrow hallway was lined with stalls on both sides. They didn't have the curtain-like entrances he was used to in American stores, but rather real wood doors, with wood walls. Kyra stepped inside an empty one, pulling her father with her. With the two of them in the stall there was barely room to move. One wall had a full length mirror, with a small bench on the side opposite the mirror. The light was dim, but there was plenty to see. Kyra hung the top and jeans on a hook on the back of the door. She and her father bumped into each other nearly every time they moved. "What are you doing?" Dan finally asked. "You mean, 'What are WE doing?" Kyra said with a smile. "OK. What are WE doing?" She put her arms around her father's neck. Then she pulled him towards her, got on her toes, and kissed him. At first it was just lips-to-lips. But Kyra's tongue forced its way into Dan's mouth and the kiss became stronger. Dan pulled away. "Kyra! What...I don't think...let go of me!" He put his hands around her arms and pulled them off his neck. She pressed against him, pushing him against the back wall of the little cubicle. "Oh, Dad. What's wrong? You've been staring at me all night. We can finally be alone and now you don't want me." Kyra's pout almost always caused her father to cave in. This would be a severe test of her ability. "It's not that I don't want you...I mean, I don't WANT you...but it's not that I don't love you..." He looked around, wondering to himself if anybody could hear their conversation, even in the muffled tones in which they spoke. Kyra practically threw herself on her father and they kissed again. She made sure he could feel every inch of her body. Likewise, she felt his cock pressing against her. This time it took a little less force to get inside his mouth. "OK," Kyra said, ending the kiss. "But stay here and let me know what you think of these clothes." She was between him and the door—he was on one wall, she was as close to the door as she could get. There was maybe an arm's length between them. She looked him straight in the eye, grabbed the bottom of her sundress, and unhurriedly pulled it over her head. Kyra freed her arms of the garment and laid it on the bench. She stood in front of her father in nothing but a thong. Her firm breasts rose proudly, nipples extended from the excitement of the moment. She watched his eyes follow her perfect body down to her waist and legs and back up to her breasts. Then she took the new top off its hook and put it on. Like most tops she owned, it had a plunging neckline and clung to her body. She was much less interested in the top than she was in her father's reaction to the sudden turn of events. He seemed mostly entranced by the little shirt that stopped well short of Kyra's thong. "Kyra, you really shouldn't...I shouldn't be in here." Dan was not at all convincing. Kyra spread her arms from side to side. "What do you think?" Then she twirled around, allowing her father to see how his daughter's tight ass swallowed the tiny thong. She turned again and faced him. "It's...nice." She moved closer to him. "Just nice? I want you to think it's really awesome, or I won't buy it." Almost before she stopped speaking, she was pulling off the top again. Kyra leaned against her father. "Touch me, Daddy. Touch my breasts." "No, honey. I can't." "Please. Just once. Nobody can see. Nobody will ever know. Please?" She didn't know what to expect. It wouldn't have surprised her one way or the other whatever he did. But a couple seconds later, his hands were cradling her luscious breasts. Kyra closed her eyes and felt his fingers surround her tits. He squeezed tentatively. "Take my nipples, Dad. Squeeze them." Dan put two fingers around each nipple and pinched lightly. "No. Harder," Kyra urged him. Dan squeezed harder. "Oh God, yes. Just like that. It feels so good." She looked at her father now, wanting him to see how happy he was making her. His look was blank, except for a suggestion of guilty curiosity. He was about to end the little episode and use his parental power to get out of the stall, but Kyra put her hand on his crotch, instead. There was no mistaking the feel of his hardening cock. She pressed her palm against it and rubbed. Kyra said softly, "Please don't stop. Your hands feel so good. Please keep playing with my nipples, Daddy." No man in his right mind could have refused the pleadings of this young woman. Not even her father. Whether to make Kyra happy or to prevent her from taking her hand from his cock, he squeezed her nipples some more. They were fully erect now, a bright pink against her tan skin. Dan was hard enough for Kyra to put her hand around the outline of his cock and stroke it. His light-weight dress pants did not provide much of a shield against Kyra's hand. She may as well have had him naked. "Does my body make you hard, Dad? Do you want to touch me all over? Go ahead," Kyra nearly whispered. "Touch my pussy. Put your hand on my pussy, Daddy. Please." She could feel him throbbing harder. Soon she would have to open his pants to let his erection grow even more. When his hands didn't move from her breasts, she leaned up and kissed him passionately. That's when she felt him slide his hands down her body, over the top of her thong and onto her pussy. One hand stayed in front while the other reached behind and found her smooth ass. Kyra moaned into his mouth as they continued kissing. She fumbled with his belt; his zipper; the button on his pants. Once they were open, she let the pants fall to the floor. She felt his boxers. She found his cock again and gripped it while Dan rubbed her now-moist thong. As soon as Kyra's hand slid inside his boxers and took hold of his cock, Dan resigned himself to the fact something crazy was about to happen. He held back no more, feverishly kissing his daughter, gripping her ass with one hand and pushing her thong aside with the other so he could find her clit. A shockwave burst through her body when Dan found it. "Oh, God. God! Yes! Oh, please. Rub it harder. Harder!" Dan met her urgent requests for a short while, but then searched for the opening to her cunt. As Kyra continued to stroke him, he plunged one, then two fingers deep inside his daughter's body. She buried her head in his shoulder and squealed in pleasure, trying not to be heard. "Don't stop. Don't stop. Make me cum, Daddy." The words were shocking for Dan to hear, but the lust that was building inside him made them sound all right. He began to wish his cock was in her instead of his fingers. He wanted to fuck his daughter and bring her to an orgasm. "My clit, Dad. Rub my clit. I'm going to cum." Kyra had her head against his, speaking into his ear as quietly as her excitement would allow her. Doors of stalls around them opened and closed, but they kept playing with each other, desperately needing to finish what Kyra started. Dan found her clit again. Kyra moaned and pressed herself against his hand. Precum spread over her fingers as she fondled her father's cock. "Yes. Yes! Now. I'm cumming!" Kyra said. As her father rubbed her clit, Kyra leaned on him and started to cum. She thrust her hips up and down as if to fuck his hand. Dan held her by the ass while maintaining a constant rhythm back and forth across her clit. He felt her body tense up, release with sudden quivering, and then tense up for another wave. He heard her gasp over and over, but never once did she ask him to stop. Finally, she collapsed in his arms, seemingly lifeless except for her ragged, deep breathing. "Oh my God," she managed to say. "Wow." Dan brushed her hair. He was about to suggest they get dressed when Kyra slumped to her knees. Instantly, she had her father's boxers down and was running her tongue up the length of his rigid cock. "No, Kyra. No," he said. But the moment her lips wrapped around him and he felt her tongue stabbing at his cock inside her mouth, Dan was quiet again. Her head bobbed up and down on the shaft with expertise Dan had never experienced before. He grew harder than he'd ever been in just seconds. Kyra knew she would make him cum when she felt him begin to fuck her mouth. His hips methodically drove the cock deeper into her with each passing minute. She eagerly accepted it. No more words were said until Dan's uncontrollable moans were replaced with, "Ohhh, yes!" She wanted to urge him on, but didn't dare take her mouth off his thick cock. She didn't want to miss a drop of his precious cum. When he grabbed the back of her head and held her in place, she prepared herself. A loud grunt, followed by another, preceded the first blast of cum. Like a pro, Kyra kept on sucking her father's cock, taking in all the cum he could produce. Well, almost all of it. A small stream trickled down the side of her mouth and onto her chin. But she never let go of the cock with her hand or mouth, which resulted in a prolonged orgasm and a still-hard cock even when Dan couldn't cum any more. "Jesus, Kyra. What did we just...do?" Dan panted. "I think we both came," Kyra said while wiping cum from her face. "It's obvious you did. And I know I did." It only took them a moment to dress. Kyra put the new top back on its hangar, grabbed the jeans she never tried on, and opened the door to the dressing room. The couple walked back into the noisy, busy store without a second look from anybody. Kyra then took her father's hand and led him out of the shop, tasting him on her lips as she licked. "It's almost time for the show. We better get going," Dan told his daughter. "Good," Kyra said. "It will feel good to sit down." They both smiled. *** "Let's go down to the beach," Kyra said to her father as they approached the resort after the show. She looked up at him pleadingly and Dan agreed, believing he owed his daughter a favor after the dressing room incident. But he was rightfully suspicious of her intentions. It was a warm, calm night with virtually no moonlight. By the time they were on the sandy beach, it was difficult to see more than a few dozen feet in front of them. They walked for a minute, then noticed they were heading straight for one of the igloo-shaped beach shelters that existed every hundred yards or so along the resort's beach. The shelters were a great way to get out of the sun during the day, with openings to let the breeze pass through and a curtain in the front for privacy. As they passed by the front of the shelter, they could both see it was unoccupied. "Come on," Kyra said, tugging on her father's hand. Dan reluctantly let her pull him in, getting on his hands and knees once inside. Kyra closed the curtain. "Aren't these things great?" she gushed. Dan had turned and now sat on the sand, facing Kyra. "I wonder what people use them for?" he asked innocently. It was one of his first attempts at humor the whole night and Kyra was thrilled he was acting a little more relaxed around her. "I don't know. Maybe wild sex." As she spoke, she dove onto her father, pushing him onto his back in the sand. She kissed him. Dan spread his legs, allowing Kyra to settle onto his body. Dan's hands were all over Kyra's ass and back, pulling at the dress that covered her silky skin. When the kiss ended, Kyra leaned up, pulled down the straps of her sundress and exposed both breasts. She put one directly over her father's mouth and let him lick the nipple. Then he took the breast in his hand and put his mouth around as much of it as he could. "Ummm, that's so good," Kyra moaned. "Suck harder. Bite my nipple, Dad." He gladly obeyed. His cock throbbed once again as his daughter gave her body to him. Dan alternated between Kyra's tits, causing both nipples to grow until they hurt. But the sensations that ran through the rest of her body when he bit them offset any pain. "Do you want me to suck your cock, Dad? Do you want me to lick it and put my lips around it?" He didn't answer, still unable to make himself say the words to his daughter. Kyra ground her hips into him, pressing against his erection harder and harder. "Tell me you want me to suck your cock. I want to taste your cum again, Dad. Tell me you need to cum and you want me to lick your cock all over." The words were like electricity running through his stomach and down to his cock. It hurt to be constrained inside his pants and boxers. Kyra's body rubbed across it with more intensity, driving him crazier. "Oh, Kyra. Baby." "Tell me. Tell me!" "I want you, honey." "What. What do you want, Daddy?" "I want you to suck me. Suck my cock. Make me cum again." Kyra smiled in the darkness. She opened his pants and reached for the cock she craved. She pulled it out through the opening in his boxers and quickly surrounded it with her mouth. He was totally hard within seconds. Dan watched his daughter's hair sway with the bobbing motion of her head. He watched her breasts bounce along with her movements. "God, Kyra. You're so good," Dan moaned. She responded by increasing the tempo and pressure on his cock. Her hand stroked the base while her lips and tongue worked on the remainder, especially the head. She tasted his precum, amazed at his ability to get so hard so soon. Kyra was undecided on whether to try to fuck her father or keep it simple this first evening. He wasn't helping any by giving any indications of his own desires. Ultimately, she decided there was plenty of time on the vacation for them to fuck. She'd just let him enjoy her mouth for now. She could feel her father's body stiffen a little more with each passing moment. It wouldn't be long. "I want you to cum on my tits, Dad," Kyra said. "I want to watch you masturbate and cum all over me." Her head dropped back down on his cock and Dan could not find it within himself to say 'No'. All he could think of was how dark it was and how that would make it less...wrong. "Tell me when," Kyra added without any hint he might decline. Another minute passed. "Now. Now!" Dan cried out in privacy of the little shelter. Kyra lifted her head and moved forward so her breasts were right above her father's erection. Dan hastily grabbed his cock and began stroking it. "That's it Dad. Cum for me. Cum on my tits." Dan raised his ass off the ground as the first shot of cum rose through his cock. The tip of his cock hit Kyra's right breast and then exploded with a long stream of sperm. A couple more strokes and a second blast covered both tits. A half dozen shots later, Kyra was adequately covered with warm fluid and Dan was finished. She rolled onto the sand, her father's cum flowing in a new direction over her chest. "That was GREAT!" she exclaimed. Dan smiled at her in the darkness, unable to admit his own feelings of satisfaction. The Twins' Obsession Ch. 02 "Promise me we'll fuck on this trip?" Kyra said, using her fingers to spread the cum over her nipples. "We'll see, hon. We'll see." Kyra pulled off her dress, leaving her in just her thong. "I'm going in the water to clean off. Don't leave me." Dan watched his daughter's beautiful ass slide out the entrance of the shelter and into the darkness of the night. The Twins' Obsession Ch. 03 The Robertson's were in Day Three of their vacation in the Bahamas. Eighteen year old twins Kyra and Kevin, along with their parents Dan and Amanda, were bonding like never before. The foursome shared a resort suite, with the twins in one bedroom and their parents just a door away. There was a communal living room in the middle accessible from each of the bedrooms. Each area was separated by locked doors. It would soon be evident that the locks weren't necessary. Beautiful Kyra and her brother Kevin were already sexual partners before the vacation. But Kyra had correctly sensed a growing attraction between Kevin and their mother, an equally attractive woman. Kyra had arranged for herself and her Dad to go out on a 'date' the evening before, leaving Kevin and Amanda alone. As Kyra expected, it turned into a hot night in the living room between mother and son. What Kyra didn't necessarily expect were the two encounters she had with her Dad while they were shopping and exploring the beach at night. Yes, she was the one who initiated the oral sex episodes, but she hadn't expected Dan to be such a willing subject. So Dan and Amanda awoke the next morning unaware of each other's experiences. Nor did they know that their kids were in the next bedroom plotting further adventures. Kyra was anxious to progress to the next level with her father—a good fuck. It was just a matter of how, when and where. Dan was obviously captivated by Kyra's perfect body, so the 'how' was going to be easy. But when and where? ###### "What are you going to do today?" Kyra asked her brother. She was drying her blonde hair with one towel, another one loosely wrapped around her. They stood at opposite ends of the bedroom. "I don't know. Just the beach, I guess," Kevin said, pulling a pair of shorts onto his otherwise naked body. "How about you?" "Don't know. But I'm in a flirting mood." She sat on the edge of the bed, her legs crossed. She was exposed up to her pussy and her breasts were barely hidden by the dropping towel. Kevin took notice. "God help whoever you're stalking now." "I don't stalk," Kyra protested. "That's a mindless task. I put a lot of effort into my flirting." Kevin was walking past her, on his way to the bathroom. "Effort? How much effort does THIS take?" He reached out and put a finger under the towel, between her breasts. With one pull the towel fell open. He kept walking...after taking a good look at the incredible breasts he was so used to seeing. "Hey! I'm not THAT easy. I'm not just another gorgeous body, you know." Kevin laughed, closing the bathroom door behind him. Kyra stood in front of the dresser mirror. She fluffed her hair with both hands, admiring the firmness of her breasts. Her tiny waist widened into luscious hips and the V of her pussy begged for attention as her hands slid downward. She turned to check out her ass. As she did so, her eyes caught sight of the sandy beach beyond the room's balcony. She walked to the sliding glass door and looked out at the ocean. A young man walked on the beach. He might have been fifty yards away. Kyra watched him from inside the room, her naked body nearly touching the glass. As if drawn by a hidden power, the man's eyes rose to Kyra's balcony. Then to the door and, finally, to Kyra. A current seemed to flow through her. Heat surged down and collected between her legs. The man smiled. Kyra smiled back and turned to walk way. But she stood for a second, then allowed her ass to ever-so-slowly disappear from his view. "This is too easy," she thought to herself. It wasn't strangers on the beach Kyra Robertson was after on this day. It was her handsome father, the real estate agent with the beautiful real estate agent wife. Kyra didn't want his money, and she already had his attention. She wanted his cock—the one she twice sucked to orgasm the evening before. And she wanted it deep inside her cunt. Dan Robertson was having trouble getting his daughter off his mind. He kept seeing her topless body in the cramped dressing room. He saw her mouth around his cock. He saw her in the beach shelter, sucking him until he came on her tits. He saw her crawling out onto the beach in just her thong. He felt only a twinge of guilt when his cock got hard thinking about Kyra. Dan and Kyra's combined thoughts were bringing them closer and closer to the most taboo of all sex acts—an act Kevin and Amanda were already very familiar with. ###### Dan was beginning to fall into a regular daily routine: spend the morning with Amanda, eat lunch, go out to the beach with Amanda for about an hour, then return to the room for a couple hours. He found it incredibly boring just sitting in the sun, despite the abundance of bikini-clad females. Kyra had taken note. It seemed to her those two or three afternoon hours would be a prime time to be somewhat alone with her father. She knew Kevin and her Mom would never waste a perfectly good afternoon inside the room. The 'when' and 'where' were becoming more evident. The problem for Kyra was sneaking away without raising suspicions among the rest of the family. She helped set things up at lunch by saying there was a sale in one of the nearby beach accessory stores she wanted to go to when it got too hot in the middle of the day. She knew her mother wouldn't sacrifice ideal tanning time and the men, of course, wouldn't even consider going shopping with her. Well in advance of the time she figured her father would head inside, Kyra put on her cover-up and announced her intentions to hit the sale. She gathered up her stuff, shoved it all inside her large bag, and headed towards the store. Once off the beach and well out of view, she detoured back to the resort. Once inside her room, Kyra opened the connecting door to the living area. She left it about half open, not wanting to be too obvious. Then she determined where she would have to stand to be seen from the couch or chair her father most often used. Next, she had to find an outfit that still had a tag on it. Kyra knew her father would never be able to distinguish one store's tag from another, so anything revealing with a tag on it would do. Of course, nearly everything she brought with her was revealing, so she quickly found an appropriately sheer, never-worn top. It buttoned down the front and was practically see-through. "Perfect," she thought to herself, holding the blouse in front of her. The last change was out of her bikini and into a thong. No bra, just the thong. Then it was time to wait for her father. Half an hour later, Kyra heard the door opening between her parents' bedroom and the living room. She rolled off her bed and pulled on the new top. She left it unbuttoned. The bottom of the shirt rested gently on the very top of her ass—exactly the look she wanted. She pulled up on the front of her thong, tightening the material that clung to her pussy. Kyra had determined she was NOT simply going to barge into the living room on her father. She would put on a show first; perhaps allow him to make the first move. At least that was the plan. Kyra walked across the bedroom, past the open door, and into the bathroom. A minute later, she came out and walked the other way, purposely avoiding looking towards her father, who she hoped was sitting in one of his usual spots. Her top was still hanging open and exposed a large portion of her breasts as the breeze pushed against the light material. She didn't expect a response the first time...and didn't get one. So she walked to the closet next to the bathroom. She knew from her earlier testing that Dan could probably see her—and her bare ass—as she ostensibly searched for something amid the hanging outfits. Kyra felt the shirt rise even higher on her back when she got onto her toes to reach higher. When she decided that particular show was over, she went back to the bed and waited. "Did you buy anything, hon?" Kyra couldn't believe it. She couldn't have wanted him to ask a more perfect question. Or was he the one taking charge this time? She took a deep breath and walked to the half open door. "Oh, hi Dad. I didn't know you were there," she lied, looking through the doorway. She hid half her body behind the door in a display of bashfulness. "Yeah, I got a couple things. I think this top is awesome." "Let me see," Dan said, turning on the couch to get a better view. Kyra stepped from behind the door, using one hand to hold the two sides of the top together a little below her breasts. It was an incredibly erotic view she presented her father, with her tiny thong below and the transparent top above. "Do you like it?" she asked. She turned one leg slightly in front of the other as if to cover up her pussy. "Very much." Kyra walked towards him, letting go of the shirt. She saw her father's eyes quickly take in her entire body. She stopped before reaching the couch. "It wasn't cheap, but there are so many things I can wear it with," she said with a satisfied smile. Dan withheld the temptation to say that what she was wearing it with now was perfectly fine with him. "It's nice." Kyra turned around, and it wasn't to show him the back of her shirt. She was in full flirtation mode now. When she figured her father had had enough time to study her firm ass, she turned again. As she did so, her breasts were bared until the shirt fell back into place. She walked to the back of the couch. Leaning against the back of the couch just beside her father, she said, "I guess I'll need a bra with it if I'm in public." Dan turned to face her, but quickly turned back towards the TV when he realized he was only inches from her breasts. "Yeah. And maybe button it, too." Kyra moved so that she was directly behind her father. She slid her hands down his bare chest. Her breasts pressed against the back of his head. "I like showing you my new things, Dad." He couldn't turn or he'd have his daughter's breasts squarely in his face. Her hands reached the top of his boxer style swimming trunks and he wasn't sure what he wanted her to do next. She totally surprised him by throwing her legs over the couch and landing next to him in one swift, athletic move. Her hand was instantly in his crotch. Dan's eyes were on Kyra's chest. "Kyra, not here." Dan felt her fingers tighten around his stiffening cock. "In the dark on the beach is one thing..." "Lick me, Dad," Kyra mewed. "Take one of my breasts in your mouth and lick it. Please." She was thrilled at the instant reaction she got from his cock. Already it was causing a tent to form in his lap. "No, hon. We can't. Not here." "We have a couple hours," Kyra said, stroking him through the soft material of his trunks. "And you know it." If Dan could have willed his cock back down to normal size, he would have. But he had a better chance of making it snow. Kyra's nipples were beginning to grow and her tits were so close...so close. Kyra leaned forward almost imperceptibly. So did her father. He opened her shirt on one side and put his tongue on her nipple. Dan heard Kyra gasp when his mouth closed around the end of her breast and he began to suck. His tongue played with her nipple for a second before he bit down with her lips. Then he used his teeth—lightly. She moaned out loud. Kyra's hand was inside her father's trunks. She gripped his cock firmly and stroked it, increasing the pressure each time Dan swiped his tongue across her breast. She frantically began to push the trunks down, her father never losing contact with her breasts. He was alternating between them now, pushing her flimsy blouse off her shoulders and onto her arms. Once she had her father's swimming suit well down his legs, Kyra flung off her blouse and straddled him so she sat in his lap. Dan's cock pointed up towards his stomach, fully erect and unable to resist Kyra's next move. "Now...just relax, enjoy the ride and don't say a word," Kyra instructed her Dad. "But...," he tried to add. Kyra placed her palm firmly across his mouth. "Shhhh. Someone might hear us." It was the last thing SHE was concerned about, but Kyra knew it might scare her father. It worked. She moved up until her thong-covered pussy rubbed against his cock. They both felt the growing heat between their legs. Kyra moved so that her Dad's cock massaged her clit each time she moved her hips. She tilted her head back in pleasure. Dan put his hands around her breasts and kneaded them gently. The soft skin was so tempting, and watching the breasts shift with his hand movements was extremely erotic. He really needed to cum. Dan was so wrapped up in Kyra's breasts that he didn't realize she had pushed aside her thong, exposing her pussy. But as soon as his throbbing cock felt her warm wetness he comprehended what was happening. She was pressing her pussy lips against the tip of his cock. He was an inch away from fucking his daughter. Nothing at this point, short of someone—like Amanda—walking through the door, would have stopped Dan and Kyra from taking the final step. They were both too horny and too aroused to pull back now. Kyra reached down and pulled up on Dan's cock. It rose like a pole and twitched in her fingers. Kyra situated it directly below her cunt, but only let the tip enter her. "Just enjoy the ride," she repeated to her father. Then she lowered herself upon him. She was so wet there was no resistance at all. He was so hard it didn't matter. Kyra let her ass rest on Dan's legs for a second, allowing them both to enjoy the feeling. After a brief moment, Kyra began to raise and lower herself on her father's thick cock. She remembered how wonderful it felt in her mouth. It was even better now, deep inside her cunt. Dan would have agreed had she asked him. He put his hands on his daughter's ass. He squeezed her cheeks as she continued to ride his cock. Then he grabbed her at the waist and synchronized his own movements with hers. Dan watched Kyra's tits bounce wildly as their pace quickened. He couldn't remain silent any longer. "God, Kyra. That feels so good." She smiled and tightened her cunt muscles around his shaft. "I know. Fuck me harder," she encouraged him. Dan pushed his cock into her with even more force. Their bodies smacked together in the stillness of the room, their quiet comments and hard breathing the only other sounds. "Harder, Dad. Harder! Fuck me!" They were bouncing on the couch, Dan's cock disappearing into Kyra's cunt with increased speed. He'd never felt anyone as tight and wet as his daughter. He wanted it to last, but knew he'd cum quickly. Kyra sensed it. She slowed down and rotated her body around his cock. It drove both of them wild to not be fucking hard. But the sensation of her cunt slowly, slowly rising and falling on the cock made up for it. She squeezed him again. Just then something across the room caught her eye. She looked through the open door to her bedroom and saw Kevin. Then her Mom stepped out from behind the door and stood next to him. The look on Amanda's face was priceless. It was shock and arousal all rolled into one, with arousal seemingly winning out. Kyra saw Kevin whisper something into Amanda's ear. Amanda smiled nervously. Then Kevin motioned for Kyra to continue. "Oh, God. God! Let me cum in you, Kyra!" Dan was saying. Kyra loved it when they begged. To hear her own father saying it to her was enough to bring her to the brink of an orgasm. "Please," Kyra said. "Please cum in me now." She had added reason, at the moment, to encourage him. They began to fuck again...hard and with one purpose in mind. They both heard the squishing sound of Dan's cock being thrust into her cunt. They both smelled the sex. "Yes! Yes!" Kyra cried out as she rubbed her clit. Another moment passed. Then Dan said: "Now. I'm cumming! God, I'm cumming!" Kevin and Amanda clearly heard his shouts of delight. They could see his cock driving into his daughter's cunt. Kyra watched him close his eyes, throw his head back, and pound his cock into her. She heard him grunt. Then the first shot of cum blasted high into her cunt. It was quickly followed by a second. "That's it, Dad. Cum in me. That's it!" Kyra got a quick glimpse of her brother and Mom watching her fuck her father. They were trance-like in their attention to the couple on the couch. Dan kept cumming and Kyra kept rubbing her clit. "Yessssss, Dad. I'm cumming now!" They came together for several seconds, moaning and groaning in unison. Their combined fluids collected on Dan's cock and slid down to his balls. Kyra wondered if she'd have the chance to clean him off...in front of her 'audience'. When their orgasms ended, Kyra leaned forward against her father. His face rested on her tits, occasionally licking the still-sensitive nipples. Kyra saw the door to her bedroom close without a sound. ###### "Wow!" Amanda said softly once the door was closed. "Wow." Kevin smiled as they walked towards the bed. "Do you feel a little less guilty now?" he asked his mother. "Well, um, yeah...I guess," she replied. "But...God. How long have they been doing that?" "Probably about half an hour." Amanda gave her son an angry look. "I don't mean now. I mean...how long..." "Probably about half an hour." Kevin just stared at his Mom, who seemed to be getting it. "Oh." Amanda looked at him again. "How do you know?" "It's just an educated guess. Trust me," Kevin said assuredly, moving closer to Amanda. "I will...for now," she replied. His hands were reaching for her body. She was more than willing to let him touch. "Are you as horny as I am?" Kevin asked. His hands rested on his mother's breasts, covered only by a skimpy bikini top. "Maybe more," Amanda sighed. She felt his fingers close in on her tits, scrunching the thin bikini material as he massaged her. She nervously fumbled with the tie at the back of her top. Once it was undone, she lifted the bikini off her breasts. Kevin swiftly lowered his head and began sucking on one of her large nipples. With his eyes closed, Kevin could not distinguish between Kyra's breasts and her Mom's. Both women had full, firm tits with nipples that grew dramatically when aroused. Amanda must have been VERY aroused. She moaned each time he forced more of her breast into his mouth, running his tongue roughly over her nipple. She grinded her pussy against his ever-hardening cock. "Fuck me, Kevin," she begged. Kevin forced her down onto the end of the bed with a powerful move that bordered on dominating. She was on her back with Kevin grabbing at her bikini bottom. "No. From behind...please," Amanda looked up at her son with a look of desire that no man of any age could have refused. Kevin pushed his mother onto her stomach. He gripped the sides of her tiny bikini and yanked it down her legs. Just as rapidly, he removed his own swimming suit. His cock sprung out already erect. He took a second to admire the beautiful, round ass in front of him. Very few women Amanda's age could boast such a perfect pair of cheeks. Despite his youthfulness, Kevin appreciated fully what he was looking at. He grabbed his mother by the waist and pulled her up. Amanda put two hands on the bed and pointed her ass back at her son while leaning over. "Spread your legs," Kevin demanded, correctly sensing Amanda was liking the rough stuff. Amanda obeyed, her cleanly shaven pussy glistening with moisture already. Her tight ass lured her son's pulsating cock towards it. Kevin tried to control his desire, but it wasn't easy. "Say it again," Kevin said. "Fuck me. Hard!" "Where?" the son asked. "Fuck my pussy, Kevin. Please put your cock inside my cunt." Kevin placed the tip of his cock at the entrance. "Like this?" The Twins' Obsession Ch. 03 With one sudden, violent thrust he was inside her. Amanda gasped, but withheld an outright scream. She buried her head in the bed to stifle the next series of moans as Kevin's cock began to slide in and out of her. The combination of pain and pleasure nearly brought her to tears. Kevin put one hand on his mother's right breast. He pushed it up against her chest, then rolled his palm over her nipple again and again. He let it fall back into his hand before rolling the nipple between his thumb and forefinger. Amanda's moans assured him it was OK to continue. Amanda reached down and played with her clit, occasionally letting her fingers rub against Kevin's cock as it pumped into her. Her clit was extended to its full length, sending waves of delight through her body each time she touched it. There was plenty of moisture available near Kevin's cock whenever she needed it for lubrication. She couldn't ever remember being so ready to cum. The force of her son's cock ramming into her from behind caused Amanda to fall onto the bed. That was fine with her because she could muffle her cries of delight in the cover. She gripped it with both hands and concentrated on the unbelievable feeling of Kevin's long, thick cock intensely fucking her. "Yes! Oh God, Kevin. Yes! Almost there," she told him. "Cum for me," he said. "I want to hear you cum." "Fuck...fuck...yessssss!" Amanda pushed her ass back against her son's body and prepared for her orgasm. He held her tight by the waist and pounded her harder. The headboard began to bang against the wall as Amanda's muted screams were absorbed by the blankets. Kevin felt her cunt tighten around his cock with each wave of her orgasm. He slapped her ass cheek...again and again...a little harder each time. Amanda started to cum again. Kevin held out as long as he could. But eventually he, too, had to cum. When it seemed his mother was spent, he pulled his cock out and began stroking it above her ass. Just a few seconds later he was pouring long streams of cum over it. "Oh, Kevin. More! Cum on my ass some more," Amanda said. He complied with a couple more spurts of cum. Then he used his cock to spread it over the areas made pink by his spanking. When he was done he laid on his mother's back, grinding his cock against her ass some more. "Is THAT what you wanted?" he said, playing with her fine blonde hair. "Ummmmm," she sighed. "And more." "How many more days are we going to be here?" Kevin didn't expect an answer. All he heard were contented sighs. The Twins' Obsession "What do you want to play?" she asked him. "I think the slots. I think that's more my style," Kevin said modestly. "OK. I know some good dollar machines that you'll like." She took his hand and led him through the crowd. They found an empty seat in a long row of slot machines and Amanda let Kevin take it. With only a few minor instructions, Kevin was into the flow of things. He lost about thirty dollars before starting to hit some winners. When he was still down about twenty dollars he finally had a seventy five dollar win. He cheered when he saw it and Amanda joined in. She wrapped her arms around his neck from behind and kissed him on the side of the face. He felt her hair on his neck; he smelled her perfume; he felt her skin against his. He instinctively turned his head and kissed her in return. She hugged him harder. This is crazy. I can't take it much longer. A few hours later they were still up a couple hundred dollars combined. Kevin was probably fifty dollars ahead. He'd lost track, partly because he wasn't counting and partly because of the number of drinks he and his Mom had consumed. "You about ready to go?" Amanda asked after an unsuccessful trip to the roulette wheel. "Yeah. How about you?" "I'm ready. Let's go back." The cool night air came as a shock when they exited the casino. It was a fairly short walk to their resort, but Amanda still took comfort in holding onto Kevin and staying close at his side. He didn't mind. Soon, they entered Amanda and Dan's room. Kevin's Mom closed the door behind them. *** "When are Kyra and Dad due back?" Kevin asked. He and his Mom had settled into chairs in the living area of the suite. "They'll be late. The show started late and they were going to eat something afterwards. It will be a couple hours yet," Amanda said, sipping a drink. Kevin thought about that for a second. Did his mother want him to leave and let her get some rest? Did she want him to stay? "I guess I should be going," Kevin said. "No!" Amanda said much too quickly. "Please don't." Kevin was even more confused after her response. "OK. But I'm not nearly as much fun as the casino." Amanda laughed. "I love having you around, Kev." He didn't have an answer to that, so he just smiled. They managed to keep up a conversation for another fifteen minutes or so. Then Amanda was taking off her shoes, bending in her chair in such a way that Kevin had appealing new views of her breasts and thighs. He just watched as she let the shoes fall to the floor. Amanda sneaked a peek at her teenage son, who quickly looked away when he thought he had been caught staring. Amanda stood up and walked over to Kevin. She sat on the arm of his chair, her legs crossed in such a way that her dress barely covered her pussy and ass. "You got hard on the beach today, didn't you?" she asked. Kevin looked up at her, fighting the impulse to look at...or touch...her tan legs. "Maybe a little," he shrugged. "Maybe so much you had to hide behind me, then get in the water," his mother replied with a smile. "Was it my suit? The lotion on my skin?" "Both." Amanda laughed. She put her arm around Kevin's shoulder. She leaned in such a way that her breasts were almost resting against the side of his face. "I hope you're not uncomfortable around me, Kev, because you arouse me, too." "I do? I mean, you never...," Kevin didn't finish. He knew what he wanted to say, but he couldn't forget this was his mother. "I never showed it and never said anything because I didn't know if you felt the same," Amanda said. "I think you do, now. At least your body seemed to indicate it." Kevin felt his cock begin to throb at the sight of his mother's breasts pressed against the small amount of material still holding them in place next to his face. Then she stood up, stretched out her hands and pulled Kevin to his feet in front of her. She lifted Kevin's hands to her chest. She brought them forward and placed each hand on top of a breast. Kevin used his fingertips to feel the exposed skin. "Take off my dress, Kevin." He continued to feel her breasts. His heart pounded. He tried to keep from shaking. But there was no way he was NOT going to do this. His hands moved up to the little straps on her shoulders. Simultaneously, he pushed them aside until they reached her arms. He let them fall, but they stopped along her arms and the tips of her breasts remained hidden. He grabbed each strap and gently lowered them. His eyes never left her breasts. The dress began to fall in his hands and he let it get to her waist, fully exposing for the first time the luscious breasts he had yearned to see. Amanda lifted her arms free of the straps and then lowered them again at her side. Kevin suddenly realized the only way he was going to be able to touch his mother's tits was if he let go of the dress, which he did. It fell around her ankles. Amanda wore a black thong that scarcely covered her pussy. It clung to her body, hinting at every rise and fall of skin around her cunt. He would return to that in due time. First, he had to have her breasts. Kevin didn't need his Mom's help this time to put his hands on her beautifully shaped breasts. He caressed them; kneaded them; molded them in his palms and between his fingers. He saw the nipples hardening and he rolled them between his fingers. "Oh, Kevin. Yes. That feels so good," Amanda said with her eyes closed. He played with them until she said, "Lick them. Suck on my nipples, Kevin." His mouth opened and eagerly took in her left breast. This is wrong. This is just wrong. God, she tastes so good. Amanda moaned louder as her son licked, sucked and nibbled on the tips of her breasts. Then he took in more, vigorously sucking on as much of her tit as he could. His hand held it in place while his mouth worked its magic. A moment later he moved to the other breast and got more moans of pleasure from his mother. Without any urging from Amanda, Kevin put his hand between her legs. God, why did I do that? Take it away before... Shit! She's soaking wet. His mother's tiny thong could not hide from Kevin the simple fact that she was aroused. Very aroused. He pulled away from her breast for a second while contemplating what to do. At that instant, Amanda took Kevin's head in her hands and pulled it towards her. They kissed passionately, causing Kevin to rub his Mom's pussy even harder. When they took a breath, she whispered, "Touch me, Kevin. Touch me all over. Inside." Then they kissed some more. Kevin moved the thong aside and ran his finger up and down her pussy. He gathered moisture from her cunt and dragged it up to her clit. He heard her muffled moans as he rubbed harder. That's when she placed her hand on his cock and slid her palm up and down his hard shaft. She could tell it was restrained by his pants, so she deftly reached inside and pulled it up. Kevin put a finger at the entrance to her cunt. With any other woman it would have been inside her immediately. But he had to remember what was happening. This was his mother he was about to play with. But he decided there was no going back now. His finger slid inside Amanda until his knuckles hit her wet skin. Again she moaned her approval. Kevin inserted it a few more times, probing the inside of her cunt for just the right spot. "I want you, Kevin. I want you inside me." Damn. Damn. Damn. He wanted to fuck her. He really needed to fuck her. But it wasn't right. "Please. Just fuck me one time," she begged. Was this really his mother imploring him to fuck her gorgeous body? Dripping wet from arousal? Nipples and clit fully extended from his touch? "Then take off your thong," Kevin told her. Amanda was a little surprised, but ecstatic, that her son was giving an order. In her mind, she was convinced now that they were going to have sex. She slid off the thong in her best stripper imitation, providing Kevin with a couple different angles involving her ass. They both smiled when she stood naked in front of him. "Your turn," she said. "I want to see you naked." Amanda sat on the edge of a couch and watched as Kevin took off his clothes. When he finally pulled off his boxers and his rigid cock sprung free, she felt a shiver go through her body she rarely felt with Dan. Her son was big and thick and long. THIS was going to be fun. She rolled onto the couch, laying on her back with her legs slightly spread. No words needed to be spoken. They would have both done whatever the other wanted. But when Kevin got on the couch directly above his mother and put his cock between her legs, neither one wanted anything fancier than a pure, traditional fuck. "Tell me you want to do this," Amanda said. "I want to have sex with you, Mom." "No. Tell me what you want. What you really want," she urged him. Kevin did not hesitate, settling down so that their bodies touched. "I want to fuck you." They ground their hips together in imitation sex. "Tell me," Amanda begged. "I want to fuck you until you cum. I need to put my cock inside your cunt and fuck you deep and hard." "Oh God, Kevin. Yes! Fuck me now." She had his cock in her hand, placing it so all he had to do was thrust it into her—which he did with near violent quickness. Amanda squealed with pleasure as Kevin began to fuck her. She clutched at his back, running her nails up and down his skin. Her legs wrapped around Kevin's waist and they settled into a slightly more sedate rhythm. "That's it, Kev. Deeper. Deeper!" Kevin looked down at her breasts as they bounced on her chest. He took them in his hands and squeezed. Amanda instinctively tightened her cunt muscles around his thick cock, loving the way he played with her nipples. Kevin, in turn, thrust his cock harder into his mother's cunt. He wanted it to last, but within seconds he felt the need to cum. He put his hands under Amanda's ass and rode her more slowly. "I'm going to cum. Is it...OK?" "Yes, Kevin. Cum inside me. I want to feel you cum." Their moans increased in frequency and volume. Amanda put her hands on Kevin's ass and pulled him closer. As erect as he was, she still wanted more of him. Knowing he was going to cum soon, she used one hand to play with her clit. "Oh, damn. Damn! I'm close!" he warned. "It's OK, Kevin. I want you to cum. Fuck me harder." He pounded her over and over, her wetness making it easy to keep up a torrid pace. Kevin grabbed her thighs and prepared for his orgasm. "Now. Now! Yesssss!" he cried out. Amanda clung to him tightly with her legs and looked up to see the strained look on his face. His eyes were closed and his mouth hung open, grunts being emitted with each thrust of his cock. Then she felt the first blast of cum inside her cunt. She, too, closed her eyes and listened to her son groan as shot after shot of his cum filled her. She eagerly accepted his forceful fucking, feeling her own orgasm build inside her. "God. Oh God! Fuck me!" she said. Kevin felt his mother's body tense up, then erupt in an orgasm that prolonged his own. He remained erect long enough to allow her to cum as long as she wanted. He sucked her tits the best he could, despite her writhing motions. When her moans quieted and her body settled back onto the couch, he simply lay on top of her, taking in the wonderful feeling of their perspiration-covered bodies pressed together. "That was wonderful, Kevin. YOU were wonderful." They kissed as Kevin let his cock slip out of her cunt. Even then he wondered if they would fuck again soon. He wanted more. "Promise me that wasn't the last time," Amanda whispered. "I hope it wasn't," Kevin said. "I hope it was good for you." "I came didn't I?" They kissed again and rolled onto their sides. Kevin moved to his mother's breasts and sucked on them leisurely, resulting in new moans from Amanda. *** Kevin had been in his room for over an hour when Kyra walked in. He was laying on the bed in just his boxers. She threw her small purse on the table and looked over at him. "Well?" "Well, what?" he asked. "Did you guys have sex? I certainly hope you took advantage of my occupying Dad all evening. It's why I did it, you know," Kyra said with apparent pride. Kevin smiled. "Well, since you went to all that trouble...and you're not going to let me sleep until you know...then yes, we did." "Awesome, Kev!" Kyra shouted. She jumped onto the bed and fell on top of him. "Now, want to hear what I did?"
