You can't tell me you haven't thought about being with Tom at least once since you met him," Cheryl said with skepticism. "I don't spend all day and night thinking about him," Marlene replied. "But you've thought about what it would be like, haven't you?" Stacy chimed in. Marlene's face turned crimson. "Stacy! He's your husband. You're my sister. I don't think it's right to..." "Answer the question," Stacy said calmly. "Just because you're an attorney doesn't mean you can cross-examine me, you little brat." Stacy and Cheryl laughed, causing Marlene to even smile a little. "OK. If it helps any," Cheryl said, "I've thought about Tom. I think he's sexy and I'd love to spend an hour with him." Stacy grinned from ear to ear. Marlene sat stoically, although her pulse was racing and her body told her her younger sisters were right. She had often thought about BOTH of their husbands, but wouldn't admit it now. "How about spending all day and night with him?" Stacy asked. "Hmmmmm. That would be interesting," Cheryl sighed. Marlene rolled her eyes, which brought more laughter from her sisters. "OK. Here's what I've been thinking about," Stacy said, leaning forward in her chair for emphasis. "The trip we're all taking in two weeks should be great. Nassau is fabulous and the Atlantis Resort is so romantic. If the guys agree—and I can't imagine they won't—it would be the perfect opportunity to do a little exchange program. Call it swapping if you must." Stacy paused and watched for a reaction, especially from Marlene. With no outburst apparent, she continued. "I think the first and last day of the trip we should each be with our husbands. But the five days in between? I propose that each morning after breakfast, we put each of our room keys on the table, shuffled and hidden in some way. The husbands keep their own keys. Each of us takes a key. Whichever room it unlocks, that's who we're with until the next morning at breakfast. Then we do it again. You could end up with your own husband all week or somebody different every day." Stacy leaned back and waited. "My God, Stace. I'm wet just thinking about it," Cheryl said. "And I think one of us should have access to a camcorder each day. Every night before we go back to our rooms, whichever one that is, we should all get together and watch the video," Stacy added. Marlene did her best to hide the fact the whole idea was sounding better and better by the minute. But soon she'd have to commit one way or the other. "I'm in," Cheryl declared. "I'm pretty sure Doug will agree." Cheryl and Stacy looked at Marlene. After an interminable pause, Marlene said, "I'll talk to Mike." Her sisters cheered in unison and high-fived each other. "This is going to be SO cool," Stacy said with joy. ### Anybody meeting the three women for the first time would hardly guess they were sisters. Looks; personalities; whatever criteria you used, they were different. Marlene was the oldest at thirty. She was the shortest and had the darkest hair, principally because it was her natural color. She looked more mature than she was, but had an athletic figure that was the envy of many women her age. Of the three, she was by far the least likely to have cheated or even thought of swapping husbands with her sisters. Cheryl was in the middle at twenty eight years old. She had lighter, short hair that was styled perfectly in a tomboyish, disheveled look. She was independent, bordering on wild. Flirting was her favorite hobby. Stacy was twenty six, blonde by choice, gorgeous, and a first year attorney. She oozed sensuality and had already used her attributes to influence a county Probate Court judge by flashing just enough skin in the courtroom. Even other women stared at her in appreciation when she wore a bikini. The women understood their differences and got along great. Marlene and Cheryl's husbands had known each other in college and were great friends. Stacy's husband, Tom, instantly fit right in. Marlene's husband, Mike, was the question mark in Stacy's plan. At thirty three, he was seven years older than Stacy but certainly not a dinosaur. He had played small college football and still was in good shape. Like Marlene, he was conservative and quiet. Cheryl and Stacy simply considered it a challenge in their efforts to loosen him up socially. Both of them suspected he was more than competent behind the closed doors of a bedroom. So they each headed back to their husbands to gauge the acceptance level of the swapping proposal. Cheryl got no argument from her husband Doug and Stacy got quick acceptance from Tom. Marlene relied on tried and true techniques. "Think of it, honey. Twenty four hours of you and Stacy alone to do whatever you want." Marlene wrapped her fingers around her husband's cock as they lay naked under the covers. She instantly felt him harden and the blood pulse against her hand. "I can't believe three women wouldn't let their jealousies interfere," Mike replied. Marlene finally had him erect enough to stroke him from base to tip. "We don't exactly lose out in this deal," she said. "We get a week of sex, just like you. And we're adults. We know that at the end of the week our marriages will still be strong. In fact, it'll work because we've all been married long enough to let this happen. We know we've all thought about each other's husbands and decided we can handle swapping and then come back to our own man again." Mike was silent. "So, just imagine being able to run your hands all over either of my sisters' bodies. Being able to feel Cheryl's tight ass or hold Stacy's tits in your hands," Marlene said. Each new suggestion caused a twitch in Mike's cock, which was now at full erection with the head bulging. "Think of Stacy moving down to put her lips on your cock, kissing it and licking it." Marlene moved down to mimic her descriptions. "Or put you inside her mouth." The cock disappeared between Marlene's lips and Mike thought he would explode. He pictured Stacy naked, the way he had so many times before. She was on top of him with her pussy over his face and he held her tits. It couldn't have been more than thirty seconds later that Mike was pouring streams of cum down his wife's throat while her sister's likeness floated through his mind. Marlene swallowed and said, "I take it you're in." ### By the time the three couples were on their way to Nassau, all the specifics of the plan had been worked out. The couples would sightsee or go to the beach during the days, as normal, regardless of who their 'spouse' was for that day. They would eat together as a group and spend the evenings as planned. The women were free to visit their 'home' hotel rooms for clothes or other necessities as long as the 'Privacy' sign was not hanging outside. However, they could not discuss the day's happenings with their real spouse. Most importantly, any member of the group could call off the swapping at any time for any reason. They had toasted the agreement, with each of them fairly certain they would not be the one to pull the plug on Stacy's idea. As agreed upon, the first day was spent with husbands and wives in standard pairings as they settled in and explored their surroundings. The temperatures were in the high eighties, at least thirty degrees warmer than what they would have been experiencing back home. Stacy and Cheryl, in particular, were quick to pull out the tank tops and shorts and bikinis. Marlene, as expected, would take her time getting up the nerve to be such an exhibitionist. It was never verbalized by anyone, but the tension among the six vacationers grew by the minute as the day progressed and then dinner was over. Eventually, the couples retreated to their separate rooms, purposely reserved on different floors to eliminate as much accidental contact with each other as possible. In less than twelve hours, their lives would change forever. "Well, here we are," Marlene said nervously at breakfast the next morning. The circular table set for six would be perfect for their exchange of key cards. Each sister had brought with her a large beach bag containing the outfits they would need during the day, in the belief that was better than having to go back to their rooms for anything and facing the 'Privacy' sign. "Yep. Anybody want to cancel before we get started?" Doug asked the group. Unanimously, the others shook their heads. "What's the best way to do the cards?" Stacy asked. Tom laid a large cloth napkin on the table. "Put your keys under here, girls." Three identical keys were slid under the napkin. Tom reached in and mixed them up so that it would be impossible to know which was which. "Who's first?" he said. "Let's go by age today. Oldest to youngest," Cheryl suggested. Marlene and Stacy nodded. Then Marlene's hand was under the napkin. She let go of the first key she touched, grabbed the second, and pulled her hand out. The other sisters followed suit. "What about the camcorder?" Doug said. "That's right," Marlene said. "How about for that we start with the youngest and go up in age each day?" Everyone agreed, with Stacy becoming the anxious owner of the camcorder for the day. "OK. When we're done eating, I think the men should go to their rooms. After ten minutes, the women should try the key in their own rooms first, and then start trying the other rooms until they find the one that works. At Noon we'll meet in the lobby. Sound fair?" Mike said. "That works—if my hand quits shaking enough for me to do it," Stacy said. The much-needed levity helped lighten the atmosphere and a half hour later, the men were headed for their rooms. The women joked about all the possibilities and decided it would NOT be a good thing if they each had their own room keys. Soon, they were on their way upstairs. Mike had taken the ten minute interval to change into one of the resort's bathrobes. He paced anxiously until hearing the sound of a key card sliding in and out of the door. Then...silence. His heart pounded faster. 'Oh fuck,' Marlene said to herself in the hallway. Then she headed for the nearest room, five floors down—Stacy and Tom's. Cheryl got a green light from her card and entered her own room to the sound of the shower going and the bathroom door sitting open. She smiled and felt unexpected relief. Stacy was on her way to Marlene's room, various thoughts scurrying through her brain. Perhaps luckily, her elevator and Marlene's crossed paths without either sister seeing the other. Stacy walked down the long hallway, approached the door to her sister's room, and inserted the key card. With considerable anticipation, she opened the door. Mike had taken a seat by the sliding glass doors leading out onto the balcony when he heard Marlene's key not work. Now he grinned as his young sister put out the 'Privacy' sign, closed the door to the room, and laid her beach bag on the bed. "Hi, Mike," Stacy said. "Hi, Stacy. What a nice surprise." Mike stood up and they looked at each other. "This was my idea, you know," she admitted. "So, if you want to complain to anyone, I'm the one." "Complain?" Mike said. "You're the one who should be having second thoughts." She slowly walked over to him, her eyes surveying his arms and legs and the portion of his chest exposed by the robe. She had always known he was a very fit man, but Stacy looked at Mike now in a completely different way. She looked at him as a prospective partner. "No second thoughts. Those aren't the thoughts I've been having while walking up here, Mike." Stacy was close enough to touch him now, and she wasted no time. She moved her body against his and got on her toes to kiss him on the cheek. Almost before the kiss was over, she had her hand on the front of his robe, between his legs. To her astonishment, Mike was already responding. "I hope you don't think I'm presumptuous putting the robe on," Mike said. "Quit using legal terms with me," Stacy answered with a smile. Her hand lightly slid over his crotch and Mike resisted the urge to back away from the unexpected touch. His mind was slow to accept the fact that, this week anyway, it wasn't taboo. "I love the robe. But I feel overdressed," Stacy added. "What would you like me to do?" Mike bit his tongue when the first thought crossed his mind—a recollection of Marlene under the covers. "There's another robe in the bathroom." By now, Stacy could make out the outline of Mike's semi-erect cock. She squeezed it once, smiled, and walked into the bathroom, deliberately leaving the door half open. Mike tried to make himself not look as he heard her undressing. Still, he caught a reflection of her in the mirror as she tightened the belt around her waist. A moment later, she was in front of him again. The white robe barely covered her full breasts and hung open at the top of her legs. It was pulled tight around her small waist, accentuating her youthful, hourglass figure. "Too bad we have to be downstairs at Noon," Stacy said softly. "I could stay like this all day." They were drawn together by a mutual, undeniable desire that had been growing for all the years they'd known each other. Behind closed doors and with the approval of their spouses, Stacy and Mike started to kiss. It surprised both of them that the intensity increased to the level it did. Tongues met inside opened mouths and hands began to wander; for now, on the outside of the robes. Mike put his hand on Stacy's ass and pulled up on the robe, gripping her cheeks a little harder as the kiss became even more passionate. His hands slid up her back, still outside the robe, but it brought her chest tighter against his. Stacy could feel his cock, just as Mike could feel her breasts against his body. The movement of their bodies caused more and more skin to come in contact, which only heightened the pleasure for both of them. As could have been predicted, Stacy was the first to take things to the next level. Her hands sought out the opening in the front of Mike's robe and reached for his stiff shaft. "Oh Mike, that feels so nice. Please tell me what you want," Stacy sighed. "I'd like to see you, Stace. All of you." The words were like magic to Stacy. Nobody, not even Tom, had ever said those words in that way to her. It was honest and respectful and sexy. She was more than happy to comply. Stacy took a step back and put her hands on the knot holding the belt together in front of her robe. With a little more hesitation than even she would have expected, she loosened the belt and felt the robe begin to open. She let the belt go and allowed the robe to unwrap at its own pace. Mike did not hide his gaze at the partially revealed body of his wife's youngest sister. From her ample cleavage to her flat stomach to her silky smooth thighs and calves, Mike took in what little hints the open robe gave him of what lie beneath. Then he watched as Stacy put her small hands at the top of the robe and slide it off her shoulders. The next few seconds seemed to last an hour for both Mike and Stacy. As the robe slid down her arms and, finally, to the floor, Mike began to take in the magnificence that was Stacy's nude figure. Stacy felt like a stone statue, unable to move in the nervousness of being naked in front of Mike. They smiled simultaneously. "Wow. You're incredible," Mike told her. "Thanks," Stacy replied shyly. "I hope it's what you expected." "Well, I never expected to see you naked. So it's far better than what I expected." Stacy detected the ever-growing bulge in the robe between Mike's legs. "It looks like I got one vote, at least," she said, her eyes giving away her meaning. "May I?" "You may." Stacy untied Mike's robe, but didn't take it off. She spread it open and just looked at the thick cock as it attempted to reach full erection. She and Cheryl may have tried to predict what he'd be like in bed, but they never imagined the reality of the size of his cock. "Very nice, Mike. I'm afraid to ask if it gets bigger?" Mike laughed. "You have all day, and night, to find out." "I'm not waiting," Stacy said, pulling off the robe and tossing it aside. She was on her knees in a flash, stroking the cock and teasing it with her fingers and lips. A moment later, Mike's ultimate dream came true as Stacy put her mouth around the cock and slowly slid it in and out. He heard her moan as she quickened the pace and tightened her lips around the shaft. Mike looked down at Stacy's blonde hair as it bounced up and down, and her tits as they rolled back and forth with her movements. She was an angel sucking him like a pro. When he began to realize once more that this was his sister and not Marlene, the excitement took him right to the edge of cumming. Recognizing the warning signs and tasting his precum, Stacy looked up at him and asked, "Can you cum on my tits, please?" Mike almost laughed at the words. The most beautiful young woman he knew was asking if he'd cum on her tits after sucking him off. He could only smile and nod. After another half minute of her tongue and lips, Mike took hold of the cock and aimed it at her chest. Stacy looked up with joyful anticipation as Mike grimaced and prepared for the pending orgasm. With a loud grunt, he frantically jerked on his cock and shot the first stream of warm cum onto Stacy's chest. She watched shot after shot pour from the end of his cock and onto her body. He covered her from her neck to her navel in strings of semen. Several drops dripped from her nipples onto her legs as she sat back and allowed him to finish. When he was done, Stacy exclaimed, "That was fucking awesome, Mike. I'm impressed." He wanted to thank her, but was recovering. Stacy saw cum leaking from his cock and eagerly cleaned him up with her tongue. He almost had to tell her to stop before he came again. "So, it's my turn to ask you what you want," Mike finally said. "That's easy," Stacy replied. "We have all day to fuck. Right now I want you to eat me." She practically jumped to her feet and fell backwards onto the bed before the cum could flow down her body. She pushed the beach bag off, spread her legs in an erotic invitation to her brother, and smiled devilishly. The sight was one Mike would never forget, and made him wonder how many times that week he'd have the fortune to see it. He moved between Stacy's legs and looked for a second at the accumulation of semen on her body. He didn't need anything to excite him further, but the cum sliding down the sides of her tits did it. Mike put his hands under Stacy's thighs and lowered his mouth to her neatly shaven pussy. Light glistened off the moisture that was collected around the opening to her slit and he knew it might not take long to make her cum. The first swipe of his tongue started well below her pussy and didn't stop until he was past her clit. Stacy's muffled whimper was accompanied by a slight raising of her ass off the bed to meet his mouth. Mike went back down to her slit and gradually inserted his tongue until he could feel the warm interior of her cunt. More moans told him Stacy was doing fine. He fucked her with his tongue for a minute or two, and then moved up to the spot he suspected would begin the orgasm she desperately needed. The moment he licked her clit for the first time, Stacy cried out, "Oh God, yes! Right there, Mike! Yes!" For all of her husband's stamina in bed, Stacy wasn't used to a man who knew how to pleasure her this way. Sex with Tom was often fast and furious. This was heaven. And when Mike closed his lips around her clit and sucked on it, occasionally stabbing it with his tongue, Stacy nearly forgot about the joys of a big cock. Sister Swap She put her hands on Mike's head and begged him for more. "Oh, Mike. That's so fucking good. Lick it harder! Please!" Mike could feel the young woman's body begin to shake. She pumped her hips up and down as if fucking his face, but he never lost contact with her swollen clit. He put his hands under her ass and prepared for the impending orgasm. "Yes! Yessss! Now, Mike. Now! I'm cumming!" Stacy arched her back and groaned at full volume. The release from inside her body seemed out of control as wave after wave flowed through her, ignited by each lick of her clit by Mike's fantastic tongue. She clutched at the bed covers and hung on as another orgasm began. Eventually, she had to pull away from the mouth that had brought her so much delight. She laid on the bed, her blonde hair tousled in an unkempt mess that Mike had never seen before on his sister. He liked the look, he thought to himself, and wondered if he'd see it again before the day was over. ### Five floors below, Marlene was also lying on a bed, naked, with Tom straddling her body. They had spent several beautiful moments undressing each other and experimenting with foreplay. Now his erection lingered over Marlene's pussy as he got into position. She marveled at his youthful body, but her previous mental pictures of Tom's cock didn't quite match the reality. He was big, yes, but not substantially bigger than Mike. Could Tom use what he had? That was the question for Marlene. He put the tip of his cock at the entrance to her pussy and propped himself up so Marlene could watch as he slowly pushed forward and entered her. Tom saw her mouth open in silent approval of his method, and then her eyes closed. He lowered himself and felt the entirety of his erection penetrate the tight lips of Marlene's cunt. Once their bodies were together completely, he began kissing her face and neck. By the time he was starting a rhythmic thrusting of his cock, Tom was licking, sucking, and biting Marlene's tits. Her reaction assured him he was on the right track. Apparently, the sisters DID share a lot in common, he concluded. "That's it, Marlene. Relax. Enjoy it," Tom urged her. "Oh, I am," she quickly responded. "Fuck me harder, Tom." Marlene may not have known what she had done by making the straightforward request. But she soon found out. Tom took her in his arms and pulled her closer, allowing his cock to enter her deeper than she'd ever been penetrated before. She instinctively wrapped her legs around him and they rolled onto their sides. Already, Marlene was anticipating a more athletic session than she was used to with Mike. And that was fine with her. She stretched out the leg on top and Tom held it firmly while driving his cock at a new angle. "Oh my God, Tom," Marlene sighed. "You'll wear me out." "That's the idea," he said amid more powerful thrusts. They rolled some more with Marlene briefly on top and Tom roughly kneading her tits and nipples. Then he was back in control, kneeling between her legs and holding her up by the waist while they fucked. "I'm close," he told her. "Is it OK to...uh..." "Yes. Please! Cum inside me, Tom." As soon as the words were out, Marlene's own orgasm started with exhilarating force. She cried out and Tom encouraged her to cum for him. Then it was his turn. Several near-violent thrusts preceded a series of blasts that filled Marlene's cunt. After the initial shots, the couple rolled some more with Tom grunting an occasional aftershock and their combined juices flowing down Marlene's inner thigh. It was an introduction that promised to only get better as the day wore on. ### At five minutes to Noon, Stacy emerged from the bathroom in a stunning white bikini. "Jesus, Stacy. You look incredible," Mike declared. "Turn around." She stopped with her ass facing him. "Shit. And I'm supposed to watch you in that all afternoon without attacking you in public?" "Attack me in private," she said, walking past him and running her hand up the front of his swimsuit. She pulled on a sheer cover and they headed for the lobby. As was agreed upon by all three couples, nothing was said during the afternoon about what occurred in the morning. They spent time on the beach and ate at an outdoor café. The girls looked fabulous in their new swimsuits, but the tans needed some work. They assured each other that by the end of the week, if they could stay out of bed long enough, the tans would be there. By mid-afternoon, the heat was sufficient to make everybody consider taking a break inside. "Don't forget, Stace. You owe us a video tonight," Cheryl reminded everybody. "Unless, of course, it's already done." The sarcasm in her last statement was not lost on her sister. "You'll have one. What time and where?" "Ten o'clock in our room," Doug volunteered. The group agreed and went their separate ways again once inside the resort. Mike and Stacy poured drinks and took them onto the balcony. After fifteen minutes of small talk, Stacy moved over and sat on Mike's knees. "How about making a video?" she said in her sexiest voice. "And I want more than your tongue this time." Mike slid his fingers inside her bikini bottom and onto her ass. "My pleasure." Stacy spent a few minutes searching out the best angle for the camcorder to capture the bed and show her and Mike in silhouette. She had Mike sit on the end of the bed, pushed the record button, and smiled. ### At ten fifteen, Doug broke up the conversation by announcing, "OK, folks. It's show time. Stacy, will you do the honors tonight?" Everyone watched her connect the camcorder to the flat screen TV in the room. You could hear a pin drop as she pushed the play button and settled back onto the couch next to Mike. This was the point where the couples each thought to themselves that if the swapping was going to end, it would be because they were about to witness what had gone unspoken all day. At the same time, six people sat with racing hearts, stiffening cocks, and wet pussies at the whole concept. Needless to say, Marlene and Tom looked at the screen with intense interest. The video flashed on with Tom sitting on the end of the bed in his boxer shorts styled bathing suit. A second later, Stacy walked into view. All eyes were on the little ass barely covered by her bikini as she approached Tom. She stood between his legs, his knees just outside her own legs. Without hesitation, Stacy reached behind her and untied the top of her bikini. She let the strings dangle for a second or two before pulling up on the top and lifting it over her head. Stacy shook her head to get her hair back in order and then dropped the bikini top out of sight. "Oh shit," Doug muttered softly. His remark resulted in chuckles throughout the room and a punch in the arm from Cheryl. When they focused on the screen again, Stacy's breasts were clearly visible from an angle beside and slightly behind her. Mike's eyes could be seen locked onto the tits and the bulge in his swimsuit was becoming more evident. Stacy ran her hands up and over her breasts, stopping only briefly to roll the nipples between her fingers. They stood out and glowed a bright pink in contrast to her fairer skin. Then her hands moved down her body. They stopped at what remained of her tiny bikini. It seemed apparent that Stacy knew she was putting on a show; both for Mike and the audience of the recording. Her fingers slid in and out of the bikini, pushing it slightly farther down each time. Soon, the very top of the crack of her ass was visible. Then Stacy had her hand far enough inside the front to touch at least her clit. The outline of her fingers sliding up and down was easily seen. Stacy teased for a minute more before starting to remove the bikini. She wiggled as she pushed it down, ultimately letting it fall down her legs. On the screen, a good portion of her bare ass could be seen, but her pussy was just out of sight. "Turn around!" Doug said. The others roared while Cheryl landed an even harder punch. As if she heard him, Stacy pivoted to point her ass straight at Mike on the bed. She kicked aside the bikini and bent at the waist. "Oh my God, Stacy," Marlene said. But the room was otherwise quiet as everyone watched the stunningly beautiful woman show her ass to her brother, and her tits to everybody. They hung in their perfection from her chest as Stacy put her hands on her knees. Mike immediately slid his hands across her cheeks a few times, squeezing at the soft skin as he went. Stacy didn't move until his hand slipped between her legs and onto her pussy. When she leaned back up, everybody watching the video could see his fingers caressing her pussy and clit. Stacy spread her legs, arched her back, and let him play with her. Doug and Cheryl were sitting on the bed watching the video. Cheryl's hand, which had been resting on his leg, slid up and under his loose fitting shorts. She searched out his ever-hardening cock and rubbed it discreetly. But Stacy was watching and she used her elbow and eyes to make Mike aware of it. They smiled at each other. In the video, Stacy was turning to face Mike. She reached down and draped one hand around his cock. After a couple tugs, she started to remove his swimsuit. The moment Mike's cock came into full view, Cheryl gasped. That caused everyone to look over and she sheepishly pulled her hand out of Doug's shorts. "Don't let us stop you," Marlene said. Cheryl grinned and quickly put her hand back inside. Stacy had Mike's trunks off in the video and was getting onto her knees. "Yes!" Doug declared. "Do it, Stace." Marlene looked at Tom to try to gauge his reaction. He seemed to be taking it fine and his cock showed signs of life. She put her hand in his lap and felt the erection for herself. When the hand didn't pull away, Tom felt his cock push harder against his shorts. Everyone stared at the shot of Stacy sliding her tongue up and down Mike's large, thick cock. She rested it in her palm while bathing it in kisses and licks. Finally, she put her hair behind her ear and the cock disappeared inside her mouth. "Yeah, baby," Doug said. He and Tom were now rock hard with women playing with them and a gorgeous blonde giving head in a video. They didn't know where this was heading, but they liked it so far. Stacy only serviced Mike long enough to assure that he was hard and wet. Then she stood up and told Mike to lie on his back. With his erection pointing at the ceiling, she got on the bed and straddled his body, facing the camera. "God, Stacy. You don't even do that for ME," Tom said. "You never asked," Stacy replied with a smile. All eyes were on the screen as she got in position and lowered herself in tantalizingly slow motion. The head of Mike's cock spread open her slit, and then, inch by inch, the shaft slid out of view. Everyone could hear Stacy and Mike moan in unison. Once he was completely inside, they were still for what seemed an eternity before Stacy began rising and falling on the cock. On the bed in the room, Cheryl was pulling her husband's cock out of his shorts. As soon as it was free, she began stroking it in full view of anybody who cared to look away from the video. That wasn't very many. Stacy's tits were bouncing freely as she and Mike started to fuck harder and faster. Mike was holding her by the ass and the sound of their skin smacking against each other could be heard, even above their moans and words of encouragement. Soon, Mike was holding her tits and squeezing them to the delight of the audience. Marlene unzipped Tom's shorts and took his cock out. She resisted the temptation to suck on it...for now. "Please tell me we get to see the orgasms," Cheryl said. "Keep watching," Stacy replied. For five minutes, Stacy rode Mike's cock and let him fondle her tits and ass. Then it became obvious from their voices that the orgasms Cheryl hoped for were about to occur. Stacy threw her head back and tightened the muscles of her pussy around Mike's cock. Deep inside her stomach she felt the final release. She screamed out, "Mike! Yes! Oh fuck!" Blonde hair flew in all directions as Stacy let loose. The sensation of Mike's big cock filling her cunt and his hands all over her body kept her going well beyond the first orgasm. And in the middle of it all, Mike cried out to announce his own climax. "That's it. That's it, Mike. Keep cumming." Together, they lasted another sixty seconds. The sound of the bed creaking died down and the slapping of their skin ceased. An exhausted Stacy sat limply in Mike's lap. Then she rolled off, onto the bed. "Jesus Christ," Cheryl said in a loud whisper. Doug and Tom put their cocks back in their shorts, both on the verge of erupting. "Well? Did we fulfill our requirement?" Stacy asked. The others watched the end of the video as she walked in her nude perfection to turn off the camcorder. Cheryl, Doug, Marlene and Tom clapped. "THAT will hard to top," Marlene said. "I need a drink," Tom declared. "OK. Everybody get out. Cheryl and I need to be alone," Doug said. "We'll see everybody at breakfast tomorrow and we'll start over." There was no need for further discussion. Six horny people headed for their assigned rooms for the remainder of the night. There were certain to be some very tired people at breakfast the next day. ### Indeed, it was more like brunch by the time the group got back together, an apparent vote of confidence for the swapping program. As a result of the key card 'lottery', Marlene got her own room. Cheryl and Stacy swapped, much to their satisfaction. Cheryl was anxious to get involved after a 'day off' with her husband AND it was her turn with the camcorder. Stacy, of course, wanted to try every husband, and got her wish. When she and Doug first met in his room, Stacy already had a plan. She changed into a robe, came back out into the bedroom, and handed Doug a bottle of sun tan lotion. "I'm going to need this today. All over," she said with a smile. She let the robe fall to the floor and stood naked in front of her handsome brother. He'd seen every inch of Stacy's body in the video, but even that couldn't duplicate the splendor of the young woman in person. Stacy sat on the edge of the bed and watched Doug open the lotion. "Oh no. Not like that. Get naked," she told him. As Doug stripped, Stacy was more than impressed with his body and especially his cock, which already gave every indication of being larger than Mike's. She expressed her endorsement with a smile. "Good. Remember, all over." Stacy rolled onto her stomach and moved up the bed so her head was on a pillow. Doug followed her, but took plenty of time to admire the luscious ass that was spread out for his inspection. By the time he had the first few drops of lotion in his hand, he was halfway to an erection. He started at her shoulders. Just touching her skin made Doug shudder with excitement. Besides the forbidden aspect of doing this to his wife's sister, Stacy happened to be the sexiest woman he knew. Having the 'right' to spend a day and night with her was going to be a dream come true. He worked his way down her back, picking out the similarities and differences between her and Cheryl. At one point he was leaning forward and his cock accidently brushed against Stacy's side. He pulled back on impulse, and saw Stacy grin. He was at the bottom of her back. Stacy wondered if he'd go straight for her ass. But he didn't. Doug rubbed lotion in one leg all the way from her thigh down to her ankle. Then he worked his way back up the other leg. He paused at the top of her thigh, his fingers only an inch or two from her pussy. After a pause, he ran his fingers up the side of one cheek and onto her ass. Stacy tried not to show the desire she had for him to touch her pussy, but his hands were driving her wild. They floated across, around, and over her ass. Her skin gave way to every touch and his fingers molded her to his liking. Doug massaged the supple cheeks for a couple minutes before moving on. "Done. Roll over," he said. Stacy gladly complied and laid with her arms at her side, completely at his mercy. She gazed longingly at his cock which was now almost as hard as it was going to get. She wanted to say something, but let him continue instead. Doug started at her shoulders again, but this time didn't have to wait as long to reach a critical stage. Stacy's tits were right there, waiting for his touch. He'd known her for many years and never imagined a scene like this. Well, OK. He'd masturbated once or twice, or thirty times, to the thought of Stacy naked. Now her tits and ass and pussy were his. Stacy watched him touch everywhere on her chest except on her tits. Just when she was about to order him to do it, he put his lotion-soaked hand on her breast. She unconsciously lifted her ass off the bed for a second, which brought a smile to Doug's face. "Like that?" he asked. "Don't stop. Ever." He rubbed the lotion into both breasts and felt the nipples grow in the process. Any tentativeness that existed when he started began to fade as he massaged her chest. Doug's cock was now shamelessly stiff. Partially because of what he was knew was coming next. With Stacy shifting her body back and forth, up and down, based on Doug's actions, he realized it was time to move on. He quickly covered her abs and stomach with lotion and got to her legs. Instead of putting the lotion in his hand first, he slowly drew a line of cream down one leg. Then he commenced a tantalizing rub down. By the time he was done with the second leg, Stacy was on the verge of screaming for him to touch her pussy. Her legs widened each time he touched her thighs, which was often. After as much teasing as he could stand, Doug let his fingers slide up and make contact. Stacy's body jerked and her audible gasp pleased Doug. She laid with her eyes closed and her tongue sliding across her lips. Doug felt her moisture as he put his fingers between the flaps of skin protecting her pussy. He pulled his wet hand higher and touched her clit. "Yes. Doug, please." She nearly whispered the words but it was enough for Doug to know what he had to do now. He spent the next couple minutes skimming his fingers up and down her pussy. Then he used his middle finger to enter her slit. Again, Stacy raised her body to meet his hand. He slid the finger farther inside until his knuckles were against her skin. Doug stroked the inside of her hole before starting a rhythmic penetration. He could feel her muscles contracting and letting go. Stacy winced each time the finger hit a new spot and wondered how long she could hold out. The answer came when Doug took his wet finger and put it on her clit. "Yes!! Yes!!" she repeated as her body started to shake. Doug rubbed frantically and put a nipple between his lips. After removing the taste of the lotion, he licked and bit the nipple until Stacy was almost screaming. At last, she was able to cum. Stacy's head swayed back and forth as the orgasm grew, subsided, and started all over again. Doug's hand and mouth kept her going and Stacy writhed with bliss. By the time she was done, he was nearly on top of her, his hard cock against her soft leg. Several floors away, Cheryl was setting up the camcorder. She and Tom had discussed a long-standing fantasy of hers, which Tom was more than happy to say he'd help fulfill. ### The three couples sat in Cheryl and Doug's room, anxious for the video to start. "Wait!" Cheryl interrupted. "For this one, we need the right atmosphere." She turned out every light in the room and hit the play button. It was a scene of Cheryl lying on her stomach in the bed, alone, with covers pulled up to her waist. She wore some type of white night shirt. Sister Swap Several seconds later, Tom came into view. He was seemingly creeping up to the bed, as silently as possible. He wore a t-shirt and shorts. He carried something in his hand that nobody could make out. Cheryl's head was turned away from him as he approached her. Tom appeared to inspect her body for a second before getting to the side of the bed and leaning over. Suddenly, his hand was on top of Cheryl's mouth and he was pulling her head back. Cheryl's eyes opened wide and her muffled cries could be heard. "Don't make a sound," Tom warned her. The item in his hand was a long, wide strip of cloth. He wrapped it around Cheryl's head, inside her mouth, and tied it tightly in the back. Once completed, he said, "Put your hands above your head." Cheryl obeyed and Tom pulled another strip of cloth from his pocket. Soon, he had her wrists wrapped and tied tightly. He let her go. "Try to take the gag off and you'll pay," he said menacingly. Cheryl nodded, still on her stomach and having to look over her shoulder to see him. Tom grabbed the top of the blankets and threw them to the bottom of the bed, completely uncovering his captive. "Shit. I'm hard already," Mike said to the amusement of the others. "I think Tom was, too. Look at his shorts," Marlene added. Sure enough, an erection was starting to show as he gazed down at Cheryl on the bed. With her arms stretched out above her head and her bare legs extending the other way, she looked exceedingly inviting...and vulnerable. Among those watching the video, the reaction was unanimous. Every cock was getting hard and every pussy was wet. Tom ran his hands up the back of Cheryl's nearest leg. He didn't stop when he got to the bottom of her shirt. He pushed it up with his hand and revealed a very small pair of panties. Tom slapped her ass one time before backing away. Then he reached for her waist and pulled her over so that she was on her back. With the gag in her mouth, her hands tied, and the shirt and panties barely covering her body, Cheryl was the epitome of a young woman in trouble. She would have been hard to reject under any circumstances. And Tom had the green light. His hand was on her leg again, this time moving up toward her pussy. He lingered there for a few seconds and then slid his fingers over the top of her shirt and onto her tits. He was gentle with her. "Now you're mine," he said. Tom reached into another pocket and pulled out a pair of small scissors. Everyone in the room now knew the couple had planned this out well. Their excitement jumped to a new level. Tom placed the scissors just below her tits. He held the shirt tight with one hand and sliced into it. With a violent tug, he cut the shirt open to the neckline. Cheryl squirmed and tried to cry out. Tom put the scissors in his pocket. Cheryl's breasts were mostly exposed by the torn shirt and he played with them for a second. Then, grabbing both sides of the shirt, he ripped it open all the way to the bottom. The two halves lay against her body with a sizable gap in between. Of the three sisters, Cheryl had the largest breasts, although 'ample' might be as generous a description as you could apply. What they lacked in size was made up for in shape and firmness. For most men, like Tom, they were perfect. He pushed the shirt aside so her chest and stomach were visible. Tom took the scissors back out and skimmed the very tip up Cheryl's body, much to her unease. Once past her nipples, he cut open one sleeve of the shirt, and then the other. With a quick yank, the garment was removed and tossed aside. In the darkened bedroom where the video was being watched, Marlene and Mike sat together and Stacy and Doug were paired. In each case, hands were starting to roam. The relative darkness, and the erotic nature of the video, allowed for some heavy petting. One of these nights, every knew, somebody would cum during the video. Tom was placing the scissors under the leg of Cheryl's panties on the screen. The sound of the snip was clear. Another one on the other side, followed by an easy pull on the material, had Cheryl naked. She was magnificent in her helplessness. The next minute was taken up with Tom undressing. The suspicion that he had an erection was a gross understatement. By the time he pulled off his shorts, his cock was long and thick. Marlene voiced her approval with a long 'oooooohhhh'. It didn't hurt that Mike had his hand on her tit, manipulating the nipple to her delight. Doug was rubbing Stacy's clit through her thong. They all awaited Tom's next move. Instead of simply climbing on the defenseless Cheryl, Tom rolled her onto her stomach and moved between her legs. With a sturdy pull at her waist, she was on her knees. She looked back and seemed to beseech him not to continue, although the gag did its job in obscuring the words. Besides, Tom didn't seem to be listening. He stroked her ass for a moment and even kissed the cheeks one time. Then he moved forward and placed his cock on top of the crack, letting her skin act as fingers while he slid the shaft up and down. Cheryl could be heard whimpering while Tom held her in place. Her cries got louder when he let the cock slip between her legs. "Spread your legs," Tom demanded. From the camcorder's angle, the audience now had a perfect view of her ass and pussy, with Tom's cock ready to pierce whichever hole he chose. Even Cheryl's tits were visible as they swung freely under her body. Tom gave the impression of having every intention of driving his cock into her ass. The head rested in position and even disappeared for an instant until Cheryl's muffled howls made him move the cock down to her pussy. His smile indicated the pleasure he got out of the game being played. The game got more intense when he quickly and aggressively slammed his cock inside Cheryl's cunt. She was pushed forward and her face was buried in a pillow. Still, her cries could be heard as Tom began to fuck her. The realism of the scene was powerful. Foreplay was running rampant through the audience. Stacy was the only one with clothing actually missing. Doug had quietly removed her top while the others concentrated on the video. He had a tit in his mouth and his cock was firmly in her hand. Although Doug had no clue of his wife's secret rape fantasy, he thoroughly enjoyed watching it being played out. Tom was pounding Cheryl harder, with her tits in both of his hands and the nipples being pulled and squeezed. Both of them moaned as they got closer and closer to cumming. Before long, Cheryl's head lifted off the pillow as if signaling her impending orgasm. Tom used one hand to loosen her gag and eventually pulled it off. "I'm gonna cum! I'm gonna...cum. Oh fuck, yes!" Tom's thrusts sped up until Cheryl finally climaxed. Each time he drove his cock into her cunt, she moaned louder. Little by little she sank onto the bed while she came. Just before she collapsed, Tom started to cum. He managed to hold her up just long enough to empty his balls. Then they fell together onto the sheets, Tom on top and still inside her. "My God," Marlene sighed. All sex had been delayed while they watched Cheryl and Tom cum. Now it was a matter of turning the room into an orgy or keeping their promises and going their separate ways until the morning. Stacy broke the silence. "Wow. Doug and I need to go to bed. We'll meet in the morning, right?" Three more days of swapping were on the agenda and the ante had been upped when it came to the videos.
