"Who wants to go in the water?" Tim asks, turning towards the waves as he stands up. Paul's hands guiltily pull away from his sister's ass cheeks as he considers the idea of using the waves to hide his erection.

"I'll go with you," Paul answers much to Sharon's dismay. Wiping his lotion-covered hands on his swimsuit, he joins his brother-in-law and they race towards the water.

"Not me, I'm sunbathing," Sharon says, smiling to hide her disappointment about her massage being interrupted. Paul's hands felt so good and she could tell by the way he was touching her that he... that he... what? Wanted to fuck her again? Is that what she really wants, to commit incest again? Does she even know what she wants? Closing her eyes, she conjures up mental images of her brother lying back naked while she shows him what she's learned to do with her mouth.

Paul and Rick plunge into the surf side-by-side, each with his own motivation. Paul dips under the waves to hide the bulge his sister created in the front of his swimsuit and hoping the cool water will help it subside. Tim wipes his fingers under his nose, breathing in Rhonda's erotic aroma before plunging both hands into the water and rubbing them together to clean off the pussy juice.

The two men spend the rest of the morning frolicking in the waves, body surfing and wrestling like teenagers. After lunch, with their wives settled in with beach reads under a big shady umbrella, they rent boogie boards and continue riding the waves most of the afternoon. Rhonda and Sharon sit in their beach chairs, reading, chatting and cheering on their husbands, while men of all ages try not to gawk at the sexy women in their pale yellow bikinis.

After showers and a light dinner the two couples finish a bottle of wine while playing scrabble on the terrace. Rhonda smiles at Tim as she runs her bare foot up his calf, reassuring him that even though they haven't had a chance to be alone, she appreciated the orgasm on the beach and understands what he's trying to do for her.

The night is nearly an exact repeat of the night before but this time as soon as the lovemaking sounds begin from the adjacent room, Paul rolls his wife onto her back and mounts her with an urgency she's never seen from him. Still aroused from his morning encounter with his sister's bare ass cheeks, he drives his cock deep into his wife's willing pussy. With his eyes closed and the sounds of his sister's moans penetrating the thin walls, Paul fucks Rhonda with a vigor that shows promising signs of leaving her well satisfied.

Rhonda has no illusions about what's driving her husband's passionate behavior. Her brain quickly makes the connection between Paul's earlier erection while touching his sister and his reaction to the lustful sounds from the next room. Although mildly disturbed by the incestuous inferences, right now she's more concerned with how he's pummeling her pussy. Always good at compartmentalizing, she pushes her thoughts to the back of her brain, digs her nails into Paul's ass cheeks and bucks her hips as she urges him on.

"Oh God! Ohhhh God! Don't stop! Don't stop," Sharon's cries fill Paul's ears and it's just like she's there in the room with him. He pounds Rhonda's horny pussy while envisioning his sister's naked body lying under him. The louder the sound from Tim and Sharon's bedroom the harder Paul fucks his wife. He's slamming into her like never before and Rhonda is responding with her own moans of pleasure.

As Tim and Sharon lie on their backs catching their breath, he smiles at the faint but recognizable sounds coming from Paul and Rhonda's room. Maybe his idea is working.

"God what you do to me!" Sharon whispers as she snuggles up to her husband. Now it's her turn to listen to the squeaking bed, tapping headboard and barely stifled moans coming from the other bedroom. Just before she falls asleep, her brain replays the day's events, with special emphasis on her brother massaging her ass cheeks. What did it mean?

When Paul rolls off of Rhonda, he kisses her gently on the lips before turning over. This is a sin!

He admonishes himself. Even though I am not physically sinning with my sister, God can see my depraved mental sinning. Paul feels his wife's naked body spoon against his back as he fights to hold back his tears. Why can't he be stronger?

Rhonda is up early the next morning and leaves a note on the table that she's gone shopping for groceries so they don't have to eat every meal out. Tim wants to boogie board some more before the 24-hour rental period expires but Paul begs off, claiming he's too tired. As Tim heads to the beach, Paul and Sharon find themselves alone in the house. It's the first chance they've had to talk alone since they arrived.

"What happened to our vow, Sis?" Paul asks, not intending it to sound so accusing.

A few steps down the beach, Tim turns back to get his sunglasses and sunscreen. Returning to the house, he walks in through the door from the garage and just before he calls out to Sharon, hears her voice rise in the living room. Freezing in his tracks, he listens to the building argument between her and her brother.

"That's what I'd like to know?" Sharon says.

"What do you mean?" he asks, his face aglow with anger and confusion.

"You come up with this great penance, but I'm the only one who has to live it," she yells.

"From what I'm hearing through these walls, you're not living it very well," he shouts. Tim stands perfectly still, listening and wondering what they're talking about.

"Well, I was living it until about a month ago. I lived it religiously and it almost ruined my marriage," she declares. "I've been lying there like a frigid virgin, trying my best not to lose control and have an orgasm, while you're climaxing every damn time you fuck Rhonda! Am I right?"

"What are you talking about?" he yells. "We took a vow! Penance for our sin of incest! You can't just ignore that, Sis!" he argues.

What the fuck! Tim's jaw drops as he listens from the kitchen. Incest? Paul and Sharon?

Ohmygod! That's what this is all about. Oh-my-fucking-god!

"Tell me you don't climax when you fuck Rhonda!" Tim hears his wife yell. "Convince me you're not getting off with your wife, every single time."

"Of course I am," he sighs, "but it's quick and perfunctory and... and..."

"And what?" Sharon yells.

"And it's never like it was with you," he says so quietly that Tim almost misses it.

"I don't believe you," Sharon says and Tim realizes she's about to repeat the lies that Rhonda told her. He backs farther into the kitchen, quickly opening and slamming the door.

"Anybody here?" he yells, bounding into the living room. "I forgot my suntan lotion," he says as he encounters his wife and his brother-in-law standing almost toe-to-toe in the living room.

"It's in the beach bag beside the dresser," Sharon says, not taking her eyes off her brother. "I think I'll join you at the beach," she adds, quickly turning and following him down the hall.

"Are you sure you don't want to come with us, Paul?" Tim asks, coming out of the bedroom with the lotion.

"No," he says quietly. "I'll stay here and help Rhonda put the groceries away," he says, trying unsuccessfully to catch his sister's eye before she and Tim leave the beach house.

Tim and Sharon walk to the beach holding hands, each distracted by their review of the brief argument. Tim's brain is in a fog; incest, penance and a vow to never orgasm, what kind of fucked up perspective is that? He squeezes his wife's hand and wonders what's going through her brain.

Sharon's guilt almost overwhelms her as she feels her husband squeeze her hand. Tim is so good to her, but her impure thoughts of her brother keep invading her mind. Why! Why!

Tim and Sharon boogie board the rest of the morning, laughing and playing in the water. Constantly catching Sharon and helping her stay afloat; his hands are all over her gorgeous body. Squeezing her ass, touching her thigh or even cupping her breasts from behind, Tim doesn't miss an opportunity to show his affection for his wife. Without realizing it they've drifted away from the public beach to a less populated area. Tim wants to talk to Sharon about what he heard but not before he's shown her that he's not upset.

With Sharon lying astride the boogie board, Tim starts caressing her firm, round ass cheeks. Much like he did with Rhonda yesterday, he lets one finger slide beneath the fabric at the crotch of her skimpy swimsuit bottom.

"Mmmmm. Someone will see us," Sharon protests as she enjoys the feel of her husband's fingers against her moist slit.

"There's no one around," Tim replies as he undoes the tie on his swim trunks. The water is hip level, which makes it perfect for what Tim has in mind. Pulling her swimsuit bottom to the side, he slips two fingers into her slick pussy.

"Ohh!" Sharon moans. "We shouldn't be doing this out here," she adds without conviction as she spreads her legs, scoots her ass to the end of the boogie board and rocks against her husband's hand. Tim finger-fucks her with one hand while freeing his erection with the other. Before she can protest any further, he steps between her legs and replaces his fingers with his hard cock.

"Ohhhhhgod!" Sharon cries as Tim buries himself completely inside her hot, velvety snatch. Gripping the edge of the boogie board, he plants his feet solidly in the wet sand and pumps himself in and out of her by yanking the boogie board back and forth across the water. Sharon's eyes are wide open and she looks fervently around for any would be voyeurs. Finding none, she settles down onto the boogie board, spreading her legs wider and rocking against her husband's hard cock.

It's the first time he's fucked his wife from behind and even though her ass is partially covered by her swimsuit bottom, he finds the experience incredibly erotic. Based on her moans and the motion of her ass, Sharon loves it too. It gives him hope that maybe she'll agree to the doggie position in bed tonight.

"Ohhhhhhhh!" Sharon moans as she grips the sides of the boogie board and bucks her ass up to meet her husband's demanding thrusts. They climax in a torrent of heavy breathing and the sound of his body slapping against her ass as he jackhammers his cock into her inflamed pussy.

"Oh God, Tim!" Sharon cries when her orgasm rips through her body. "We're like a couple of animals mating out in the open."

"You bring out the animal in me," Tim smiles as he extracts his spent cock from her pulsating pussy and draws her swimsuit bottom back over her opening. Turning the boogie board to the side, Tim bends down and kisses his wife, pressing his tongue into her mouth. Sharon lets the boogie board slip from under her while wrapping her arms around her husband's neck and weaving her tongue around his.

"I can't believe we just did that," Sharon laughs, breaking the kiss. You'd think we were a couple of sex-crazed teenagers.

"Just the sex-crazed part," Tim laughs, slapping her on the exposed part of her ass cheek. Tim retrieves the boogie board and leads Sharon to a secluded part of the beach where they sit next to each other, watching the waves and letting their breathing return to normal.

"I overheard the argument you were having with Paul," Tim says after a lengthy silence.

"Oh that was nothing, really," Sharon says trying to sound nonchalant. Tim puts his arm around her shoulder and pulls her close to him.

"I love you more than life itself," he says, kissing the top of her head. "I will always be here for you, no matter what. Do you want to tell me about the incest, the penance and the vow?

"I... I... don't know where to start... it was all so long ago." Sharon stammers. Tim turns her face to his and kisses her gently but passionately on the lips.

"It's alright," he reassures her. "Start from the beginning and we'll get through this together."

Tim is anxious to find out what happened between Sharon and her brother so he can discredit this silly ass vow of penance. It's obvious that Paul has come up with some convoluted process for them to atone for their sins and until recently it has had a significant impact on each sibling's sex life.

With tears streaming down her cheeks, Sharon recounts the night of incest with her brother, explaining how she was drugged the first night but how she insisted they repeat the act the next morning when she was clear headed. Her face reddens with embarrassment as Tim listens intently to her rationalize how she was trying to free her brother from guilt. Tim hears the tremor in her voice and senses her heart beat faster when she talks about sex with her brother.

Sharon feels like she's going to confession after years of hiding a horrible sin. The tremendous relief of unburdening herself of her guilt keeps her talking about her brother and her dreams. Between sobs, she describes her dreams and how wet she got when he rubbed suntan lotion on her legs and ass cheeks.

Tim is flabbergasted! Paul must have been rubbing Sharon's ass cheeks while he was getting Rhonda off right next to them. What a mess! His mind is reeling with what he's just heard. Sharon is undoubtedly still lusting after her brother's affection and the way Sharon described his ass rubbing, Paul apparently feels the same way. No small part of this is how Tim and Rhonda's relationship fits into Paul and Sharon's incestuous fantasies.

"I won't contest a divorce," Sharon says, taking Tim's silence as a condemnation of her actions, "but I don't want to hurt Paul and Rhonda." She pushes back from him and starts to stand up.

"Wait a minute," Tim grabs her and pulls her back down next to him. "I said we'd get through this together, didn't I?"

"But... that was before..."

"No buts! I knew about the incest before I said that. I knew about it before we made love a few minutes ago. Honey, the last thing I want is a divorce." He lies down, pulling her down next to him and kisses her tenderly.

"Oh Tim, I really don't deserve you." Sharon cries as she clings to her husband. They lie in the sand, holding each other as the waves crash along the beach. Tim is the one to break the silence.

"Based on your dreams and what happened yesterday, I'd say you still have sexual feelings towards your brother." Sharon starts to protest but knows it wouldn't be honest so she just nods her head again.

"It's okay," Tim reassures her. "With what happened between you two, I think it's only natural."

"You do?" Sharon asks incredulously.

"Yes, everyone remembers their first love and especially their first time. Yours just happened to be with your brother." Tim says with more confidence than he feels.

"You make it sound almost normal." Sharon whispers, snuggling closer to her husband.

"Maybe not normal, but certainly not unheard of. I'm sure you're not the only brother and sister who..." Tim leaves the sentence hanging as he tries to think of what to say next. He's surprised to find himself wondering what it would be like if all four of them knew about each other's feelings. Would they willingly share their spouses? Would Paul be okay with Tim fucking Rhonda as long as he gets to fuck Sharon?

"It's still incest! It's still a sin, no matter how frequently people do it," Sharon stammers. "I can't believe you're trying to justify it." Tim silently laughs at his fantasy being shattered. There is no way Paul or Sharon would ever agree to live like that. Their upbringing would never allow it. Hell, he doesn't even know if Rhonda would agree to something like that.

"Okay, it's wrong." Tim replies, "but so is how we've spent the first year of our marriage. I don't believe you have to atone for the rest of your life for one mistake. Paul was wrong about the penance and he was wrong about the vow you took." Tim's mind is starting to question Paul's motives. Was it really penance or did he not want his sister enjoying sex with anyone else? But then why would he adhere to it with Rhonda? Because the only woman he really wants is unattainable? God, what a mess!

"It wasn't some little mistake, Tim," Sharon says quietly. "Shouldn't there be some consequences to what we did? We can't just say oops and then forget about it."

"Apparently not," Tim answers. "Neither of you has forgotten about it. You still dream about it and from what Paul said to you this morning, so does he."

"What do you mean?" Sharon asks, surprised at how anxious she is to hear about her brother's feelings even after all that's happened.

"When he said fucking Rhonda was never like it was with you." Tim says, the words coming out more harsh than he intended.

"Oh." Sharon says, her mind wandering to her brother and the confused relationship they've had. She watches Tim stare out into the ocean wondering if he's looking for answers or just trying to clear his mind of all the disgusting things he's just heard.

"I think you and Paul have unfinished business," Tim finally says. "Neither of you will be able to give your all to a healthy relationship until you've resolved the sexual tension between you."

"How do you suggest we do that?" Sharon asks, conflicted about what her husband is implying.

"How do you think?" Tim asks, kissing his wife's forehead for reassurance of his love.

"You've got to be kidding!" Sharon sits up and gapes disbelievingly at her husband.

"As a matter of fact, I'm not," Tim says quietly. "Think about it, Sharon. You lost your virginity to your brother, you still dream about having sex with him and you get aroused at his touch. Doesn't that sound like some unfinished business?" Sharon stares into her husband's eyes, searching his soul for some level of insincerity but finds none. He actually wants her to have sex with her brother.

"Why?" she asks him quietly, "Why are you saying this? Do you want me to have sex with Paul?

Do you think it will somehow improve our love life? I think we've made a lot of progress in the past month, don't you think this could ruin it? This is unbelievable," Sharon says, shaking her head.

"You two are the ones who are dreaming about each other and have spent the last year abstaining from sexual enjoyment with your spouses," Tim answers. "I think you may have created a mythical sexual experience that only exists in your memory."

"What if it isn't mythical?" Sharon whispers. "And what about Rhonda? There is no way I can do this to her." Tim weighs the merits of telling Sharon about his relationship with Rhonda and decides this isn't the time.

"What's the alternative?" Tim asks. "You and Paul continue to dream and keep believing in a mythical sexual experience that is detrimental to both your marriages. I honestly think you'd be helping Rhonda and Paul's marriage in the long run."

"Jesus, Tim," Sharon says exasperatedly, "You honestly think that adding the sin of adultery to our existing sin of incest is going to help their marriage? What have you been smoking?" Tim laughs and squeezes Sharon's shoulder, pulling her down against him, before he answers.

"Fine," he says. "Like I asked before, what's the alternative?"

"I don't know," Sharon whispers. "I just don't know, Tim," he feels her tears against his chest as he kisses the top of her head.

"We don't have to solve this right now," he says. "This has been a lot to absorb. Let's let it simmer for a while and see how it looks later, okay?"

Sharon nods, wiping the back of her hand across her eyes.

"No matter what, remember how much I love you," Tim says.

"I could never doubt that," Sharon answers, hugging him tightly. "I can't imagine any other husband being so... understanding or... open-minded? What you've suggested... I love you so much, Tim!"

"I love you, too, babe." They lie quietly on the sand, each lost in their own thoughts.

Although Tim sincerely wants to help Sharon, he also has the ulterior motive of making his affair with Rhonda seem inconsequential in comparison. It's nowhere near what Sharon and Paul would be doing. If he's honest with himself, in some small part of his brain he also finds the idea of his wife fucking her brother very arousing. He smiles as he contemplates how to help Sharon make her dream a reality.

Sharon can't even fathom what her husband is suggesting. He wants me to make love to Paul, to not only commit adultery but also incest again. She feels the heat emanating from between her legs as she tries to come to grips with her internal struggle. Even if she wanted to, she can't imagine that Paul would ever consider it.

"There you are!" Rhonda and Paul round the sand dune and trudge over to where Tim and Sharon are lying side by side.

"Have you two had lunch?" Paul asks, eyeing his sister for any sign that she wants to continue their earlier conversation.

"No, have you?" Tim answers, standing up and brushing off the sand.

"No, but I've got everything ready to grill burgers," Rhonda says, turning Tim around and brushing the sand off of his back, spending a little extra time with his swim trunk covered ass cheeks. Tim gives Sharon a quick glance but her and Paul seem to be studying each other and not paying any attention to he and Rhonda.

"Sounds great! Let's go!" Tim grabs Rhonda's hand and they start running down the beach, leaving Paul and Sharon behind.

"Do you think we'll get any time alone?" Rhonda asks as they run up to the house.

"Tomorrow," Tim answers with an ear-to-ear grin on his face. "You and I are getting up early to go visit lighthouses," he says with one eyebrow raised.

"Mmmmm. I can't wait," Rhonda says, pulling him into the beach house and rubbing her hand fervently up and down the front of his swimming trunks. Rhonda is wearing a thin sundress over her swimsuit and Tim slips his hand under the hem to massage her pussy mound through her swimsuit.

"I wish we could fuck right now," Rhonda whispers, looking through the window over Tim's shoulder to see how far away their spouses are. Paul and Sharon have stopped about a hundred feet from the house and seem to be engaged in a heated discussion near the water.

"You know the drill," Rhonda smiles, "let me know if you see them coming." She turns Tim towards the window, freeing his rapidly hardening cock as she kneels down and is stroking up and down its length before her knees even touch the floor.

"You are insane!" Tim smiles as Rhonda pumps his hard cock in and out of her warm mouth. Tim grabs her hair and picks up the rhythm, fucking her mouth as he stares out the window at his wife and brother-in-law. His arousal if obviously heightened by the imagined dialogue between the two incestuous siblings.

While Rhonda is feasting on Tim's cock, her husband is defending himself to his sister.

"I swear I don't know what you're talking about," Paul says, exasperated at Sharon's insistence that he's broken their vow. "I did not break our vow!"

"That's not what it sounded like last night," Sharon retorts.

"Well what do you expect when you're moaning like a banshee and slamming the headboard against the wall?"

"That's because I have finally become the wife I should have been for the past year!" Sharon yells, frustrated that her brother won't admit that he's broken the solemn vow they took.

"Well, I'm sorry you don't believe me," Paul says earnestly, his voice uneasily quiet as he lets his hands rest on his sister's nearly bare hips. "I've never done anything with Rhonda that even comes close to what we did."

Sharon feels her face flush as she stares into her brother's eyes. Tim was right, there is unfinished business here. She covers her brother's hands with hers, squeezing them gently against her hot skin.

"We should get back," she says, lowering her eyes and catching sight of the bulge in her brother's swimsuit.

"I mean it, Sharon," Paul says as his sister turns towards the beach house.

"I know," she whispers.

"They're headed this way!" Tim says, driving his hard cock into Rhonda's throat for the third time. "I'm so close!" he pants while gripping Rhonda's hair. She caresses his balls as her lips slide down the length of his cock. She whips her tongue around his cockhead and drives him over the top.

"Ohhhh! Fuck!" Tim nearly shouts as his cock erupts in a fountain of cum inside Rhonda's tantalizing mouth. She pumps his shaft, sucking and swallowing his bursts of sperm, finishing just in time for Tim to tuck himself away.

"Let's let the guys start the grill while we get the meat patties ready," Rhonda says as Sharon and Paul walk through the door of the beach house. She's wiped her mouth and has just taken a big swig of diet coke.

"Sounds fine," Sharon says without much inflection and follows her sister-in-law into the kitchen.

After lunch, Tim heads out to the rare bookstore, Paul settles in front of the TV and the women busy themselves in the kitchen, cutting up the fresh fruits and vegetables Rhonda brought home from the grocery store.

After an uneventful dinner, they all watch a romantic comedy on DVD. Tim makes sure he and Rhonda are the only ones interested in the lighthouse tour and arranges to meet her early the next morning.

Once inside their bedroom he and Sharon resume their conversation from earlier in the day.

"I think you're right," she says quietly as she undresses.

"About what?" Tim asks, climbing into bed naked and watching his wife disrobe.

"Unfinished business," she says, kicking her panties aside and standing naked at the foot of the bed. She waits for her husband's reaction. He just smiles.

"What makes you think so?" He asks, pulling aside the sheet invitingly. Sharon crawls in next to him before she answers.

"Just some things he said this afternoon." She moves her body against his and runs her hands down his sides. "I'm just not sure we should act on it."

"I spent the afternoon doing research," Tim tells her. "First, there is no such thing as lifelong penance. Second, there is no evidence of contemporary churches giving penance for incest. I even contacted a local priest..."

"You what?" Sharon stares at him disbelievingly.

"Don't worry. I told him I was teaching a theology class and a question came up about penance for consensual sex between an adult brother and sister. The priest said that first of all, the occurrence isn't as rare as people think and secondly, rather than penance he would recommend counseling to help the couple dissect their relationship and make a sound decision regarding theie future."

"Really?" Sharon lays her head on her husband's shoulder and tries to absorb what he's just told her. "So you really think Paul and I should..." her voice trails off.

"That's up to you," Tim says, kissing the top of her head. "All I'm saying is that it's okay with me if you do."

"I don't even know how I'd approach it with him," Sharon says, unknowingly accepting her husband's suggestion.

"Rhonda and I are leaving early in the morning and we'll be gone all day," Tim says. "Paul usually sleeps late. I bet you can think of a way to wake him up that will stifle what little resistance Paul might have."

"Oh you think so, huh?" Sharon smiles and rolls her husband onto his back. "Do you think I should practice a little on you first?"

"Wouldn't hurt," Tim laughs as his wife's hand closes around his burgeoning erection and she scoots down on the bed. Tim still doesn't understand why he gets turned on by the thought of his wife fucking her brother.

****

Tim finds Rhonda all ready to go when he emerges from his bedroom, showered and dressed, at 8 o'clock the next morning. Rhonda is wearing a pale pink cami and tight white shorts that hug her curvy hips like a second skin. Tim feels his cock reacting as he contemplates the day ahead. Pressing her body firmly against him, Rhonda reaches around to squeeze his ass cheeks.

"Everyone else asleep?" she asks as she moves her mouth towards his.

"Sharon's taking a shower," Tim whispers, letting his lips meet hers and gently parting them with his tongue. They linger, enjoying a passionate kiss and tight embrace until they hear the shower stop.

"We'd better go," Tim says, breaking the kiss and stepping back to catch his breath.

"I hope you're not taking me far," Rhonda smiles as she grabs his hand and pulls him out the door.

"Only to paradise," Tim laughs and the two lovers speed off down the road, leaving brother and sister alone in the beach house.

Sharon takes an extra hot shower, thoroughly cleaning herself inside and out. As she dries off, her mind is a jumble of contradictions but her pussy is tingling like vibrator set on high. She dabs some perfume under her breasts and on her inner thighs, still not believing what she's about to do... and with her husband's permission... no, not permission, encouragement!

She stands naked in front of the closet trying to decide what to wear to seduce her brother. She rejects several sundresses, her nightgown, a long t-shirt and finally... decides to wear nothing.

The door to her brother's bedroom is slightly ajar. She quietly pushes it wide-open and stands naked in the doorway, watching him sleep. Her heart is pounding in her chest and she's holding her breath as she tries to convince herself to step into his room. Her cheeks are flush and her pussy is itching like crazy as she slowly walks to the bed. Taking a deep breath, she reaches for the sheet that's covering him.

She has no way of knowing that Paul is in the depths of an erotic dream when she carefully pulls his covers back and settles herself on the bed next to him. He's wearing pajama bottoms with a snap fly and she's surprised to see that he is already aroused. She briefly wonders what he's dreaming about as she carefully undoes the snaps to reveal his hard, thick erection. Could he be dreaming about her?

Paul is dreaming about his sister. It's the same repetitive dream that he's has been having off and on for years. The one night of sexual debauchery that has come to define him ever since - the night he took Sharon's virginity. He regularly relives in resplendent detail the vision of his sister sitting astride his hard cock while he fondles her luscious tits and explodes into her warm, velvety pussy. But this time the dream is even more vivid and he feels the moist warmth enveloping him in a way he doesn't remember.

Having freed her brother's erection, Sharon licks it all over, leaving a thin coating of saliva up and down the sides before sucking the tip of it into her mouth. With her hand stroking up and down his slick shaft, she flicks her tongue around the head while sealing her moist lips around the tightly stretched skin of his manhood. Sharon's arousal soars as she sucks her brother's thick cock into her mouth and slides her other hand around his balls.

Paul slowly emerges from his erotic fantasy and opens his eyes to see long blonde hair bobbing up and down around his cock. He initially believes that he's still dreaming and closes his eyes hoping to extend the pleasurable feelings flowing through his loins.

Wait! This was never a part of his dream. He blinks his eyes and shakes his head, clearing the fog and finding himself staring into his sister's eyes. Their eyes lock momentarily before he suddenly panics and screams her name.

"Sharon! What do you think you're doing?" Paul yells, reaching to push her head away as he tries to scoot up on the bed. Her brother's cry startles her and she reacts by increasing the urgency of her actions.

Sharon jerks her hand more rapidly up and down his saliva-coated cock, teases his heavy balls with her swirling fingertips and fervently sucks his cockhead into her mouth whipping her tongue feverishly around it. Paul's hands freeze inches from her head as the extreme pleasure of her motions overwhelm him and he starts bucking his hips with uncontrollable desire.

"Oh Sharon!" Paul cries. "What are you doing?" His question comes out more as a sigh than a challenge and Sharon responds by sliding her lips farther down his stiff staff. His sister's attack on his hard cock is like nothing he's ever experienced and Paul thrusts his hips, vigorously matching her rhythm as he unexpectedly starts shooting his hot cum inside her warm mouth.

Paul can't breath... he can't think... what the hell just happened? His chest is heaving as he tries to catch his breath. It started as just a dream but... Sharon is actually... her mouth is really...

she's swallowing his... oh God! And she's not letting up.

Sharon sucks and swallows her brother's salty sperm, gulping it down as she continues to stroke his cock, milking out every single drop. When he is completely spent, she continues a gentle sucking motion while her fingers caress his balls and stroke the sides of his thick shaft. His cock begins to re-stiffen almost immediately and she works her tongue around it until it is fully restored.

"Sharon," Paul whispers, completely bewildered by what's happening.

Afraid to give him time to protest, Sharon pulls her lips from his cock and scrambles up over his torso. She quickly aligns her aroused pussy with his stiff cock and impales herself on him in one fluid motion. Before he even knows what's happened, his dream has become reality and his sister is bouncing up and down on his recovered cock. He reaches for her tits exactly as he did before and gives himself over to the only erotic fantasy he's ever known.

Sharon is in seventh heaven! She's fucking her brother! She's bouncing on Paul's thick cock, reliving her rocket launching fantasy of incestuous love and it was all her husband's idea!

Suddenly everything is crystal clear. She knows this is right and, looking in her brother's eyes, she sees he knows it's right, too. She's intent on making this the most memorable experience of his life.

This isn't about reliving a college memory. She shouldn't just try to duplicate the out of control, aphrodisiac-drugged sex they had before. She needs to give him something new... something better. Gradually, she slows her gyrations and starts squeezing her vaginal muscles around her brother's throbbing cock. Undulating her hips in slow motion, she leans forward until her taut nipples are pressing into her brother's chest and her mouth is close to his.

"I love you, Paul," Sharon says just before their lips meet and her tongue snakes into his mouth. She lets her tongue match the languid movement of her hips, sweeping its way around his mouth and gently urging his tongue to participate.

"Mmmmmm," Paul moans into his sister's mouth as his hands close around her smooth, round ass cheeks. His fingers press into her flesh feeling the fluid motion of her hips ripple over his hard cock. He fervently returns her kiss, following her tongue back into her mouth like he's trying to devour her.

Sharon continues the slow, fervid build up, sucking on her brother's tongue, grinding her nipples into his chest and teasing his cock with her frothing hot pussy. She hasn't kissed him in years and she's never kissed him like this... with this much passion... like her whole body is opening up to him.

By the time she breaks the kiss and pushes herself upright on his rigid cock, they are both panting and gasping for air. Their arousal is at a feverish peak and they are grinding together with animalistic lust. Paul's hands are mauling her breasts, squeezing and teasing as she slams her pussy down again and again. They are both lost in the frenzy of their incestuous coupling.

"Ohhhh! Ohhhhh! Paul! Oh, Paul! Ohhhhhhh!" Sharon rides him with libidinous abandon, once again experiencing the insatiable desire in her inflamed pussy.

"My God! Sharon!" Paul cries, thrusting into her and trying to match her feverish rhythm. Nothing has prepared him for the uninhibited pleasure of watching his sister's jouncing tits. His cock is on fire as she rides him with a salacious fury. He wants to cum in his sister's pussy. He's never wanted anything or anyone so badly. To hell with the consequences... the penance... the sinfulness, this is everything he's been dreaming about!

"Ahhh! Ahhhhh! AhhhhrrrrgggggghhhHHHHH!" Sharon clamps her pussy muscles around her brother's cock as her orgasm rockets through her body. Shaking and convulsing, she gasps for air as she rides out the seemingly endless waves of pleasure before collapsing on her brother's chest.

"What are we going to do?" Paul asks after they've both caught their breath.

"What do you mean?" Sharon asks, squeezing her pussy muscles around her brother's cock.

"What are we going to do, right now?" She smiles as she kisses her brother on the chin.

"No, I mean now that we've added adultery to our sin of incest." Paul whispers, his cock recovering quickly inside his sister's overheated pussy.

"First things, first." Sharon says, pressing her mouth to his, while undulating her burning pussy on his rapidly hardening cock. Helpless to resist her tongue or her lustful movements, Paul again gives into the incestuous desires that have been smoldering inside of him since that fateful night in college.

He wraps his arms around her, feeling her hard nipples press against his chest and their tongues get lost in each other's mouth. Oh God! This is so wrong! He thrusts his hips up and feels the moist heat of his sister's pussy mold itself around his thick shaft driving him to an agonizing level of hardness. With Sharon on top he has no leverage for driving his cock into her and he needs to drive it hard.

Without breaking the kiss, Paul squeezes his fingers into her ass cheeks, holding her tightly against him as he flips their bodies over. While she's turning, Sharon wraps her legs around her brother's torso to keep his steel rod firmly inside of her hot pussy. When her back hits the bed, she spreads her legs wide and stretches them almost straight up in the air. Paul pummels her pussy with a rapid jack hammering of his throbbing cock.

"Ohhhhhhh Paul!" Sharon cries, pulling her mouth from his to gasp for air. Her pussy is on fire and her brother's violent assault is fanning the flames, driving her to new heights of arousal.

Paul is out of control, hammering his cock into his sister with unbridled animalistic lust. He can't begin to understand that this fervent attack is the logical culmination of all the incestuous hunger and craving that has been building inside of him for years. Sharon's seduction has finally released the inhibited restraint that has kept his feelings for her buried deep in his subconscious. Now the only thing buried deep is his hard cock in her fiery pussy.

Sharon has never felt anything like this! Her whole body is inflamed with desire. Her brother's frenzied assault has ignited the deepest level of salacious hunger. She savagely claws at his back and bucks her hips to meet his violent thrusts, driving him deeper inside of her.

"Oh Paul! Oh Paul! Ohhhhhhh Ahhhhhhhhhhh!" Sharon's body stiffens, her pussy muscles contract and she shudders from head to toe as her volcanic eruption sends her hot lava gushing around her brother's cock. This is it! Even as she's in the throes of her orgasm, she feels it still building deep inside of her. Her brother is bringing back that elusive rocket-launching orgasm from her last time they were together. It wasn't just a virginal memory of her first time; it's Paul!

Sharon pushes her feet against the bed, arches her back up high and throws her head back screaming while Paul plunges his steel rod into one final time. Their simultaneous orgasmic release sends them both into fervent fits of ecstasy. Paul convulses against his sister's pussy, discharging his hot cum in wild spurts, while Sharon trembles uncontrollably beneath him, her pussy pulsating in time with her rapid heartbeat.

They continue to spasmodically thrash against each other for several minutes before their sweat-soaked bodies finally collapse in exhaustion and they gasp for air. Paul is panting and Sharon is making little cooing sounds as her body continues generating pleasurable erotic pulses.

"Oh God, Sharon," Paul whispers, still panting for breath. "We've really done it this time." His mouth finds hers and he kisses her with all the buried passion and lustfulness that he's been suppressing for so long. Sharon hungrily returns the kiss, entwining their tongues and pulling their naked bodies more tightly together.

"What are we going to do?" Paul asks, rising up on one elbow to look down at his sister's beautiful face. "We have added adultery to our sin of incest."

"Is it still adultery if Tim knows what we're doing here today?" Sharon asks her brother.

"What are you talking about?" Paul demands.

"He overheard us yesterday when he came back for the sunscreen," she says and then proceeds to tell Paul about the rest of her conversation with Tim, including his research into incest penance and his suggestion that she and Paul have unfinished business.

"Unfinished business," Paul muses. "That's a weird way of referring to it, but I guess he was right." They lay silently in each others arms for a few minutes with Paul's spent cock still nestled inside Sharon's soggy pussy.

"What about Rhonda?" Paul asks. "That's still adultery even if it isn't for you and Tim."

"I know," Sharon's answer is barely above a whisper. "Tim thinks that if we stop our penance and get this out of our system, it will improve your love life with Rhonda and every body wins."

"Are we getting this out of our system?" Paul asks with a half smile.

"I don't think so," Sharon sighs. "I think we've just permanently imbedded it in our system, at least in mine."

"Mine, too." Paul says, kissing her again to prove his point. Unbelievably his cock stirs again within her sweltering pussy and he starts a gentle rocking motion.

"Let's rest a minute," Sharon laughs, breaking the kiss and squeezing his ass cheeks to stop his movement.

"What are you going to tell Tim?" Paul asks his mind racing for a way to discuss this with Rhonda.

"The truth," Sharon answers. "I love him, Paul. I hope he knows what he started and is as open minded as he thinks he is."

"I'm going to have to tell Rhonda, too. I just don't know how." Paul says and they again lapse into a comfortable silence, enjoying the closeness of their bodies and their synchronized heartbeats. Little does Paul realize that as they speak, Tim is preparing Rhonda for that very conversation.

As soon as they had driven off, Rhonda unsnapped her shorts and pulled down the tiny zipper.

"Feel how wet I am already," Rhonda purred, grabbing Tim's hand as he glanced at his sister-in-law's open shorts.

"You are incorrigible," Tim smiles sliding his hand beneath her panties and immediately feeling the heat emanating from her moist pussy. Slipping one finger between the folds of her labia, he curls the tip of it into her wet opening.

"I'd say you're ready!" Tim laughs as he maneuvers his finger to her clit hood and draws little circles gently around it.

"Oh yeah!" Rhonda moans, spreading her legs and slipping down a little in the seat, resting her head on Tim's shoulder. As Tim continues to manipulate her clit, Rhonda pushes up to create more pressure on her sensitive love button.

"Oh yes! Just like that... don't stop," Rhonda is almost purring as Tim tries to keep his eye on the road while fingering Rhonda's clit to match her increasing urgency. The day before when he was making his plans, he had spotted a little out of the way motel along the beach and had gotten a room overlooking the ocean. That's where they were headed now, if he didn't pass it by in his distracted state.

"Ohhhhhhhhhhaaaaaaaaa!" Rhonda grabs Tim's hand to still it's motion and clamps her thighs closed, trapping his finger in her spasming pussy. She jerks a couple of times, flooding her pussy with love juice before turning her head towards Tim.

"How much farther?" she asks through half-closed eyelids.

"Not far," he smiles, "You may want to do up your shorts. A minute later Tim pulls into the motel, parking right in front of their room.

"We don't have to check in?" Rhonda asks.

"All taken care of, just like you're going to be in a few minutes," he smiles. True to his word, over the next few hours they take care of each other in a variety of ways. Tim eats Rhonda to several powerful orgasms, she returns the gesture with her tantalizing mouth on his hard cock and then they fuck to exhaustion. If it's not the rocket-launching orgasms that their spouses are experiencing, it's extremely satisfying and they end up in a tangle of sheets and naked limbs.

"I think there's something weird going on between Paul and Sharon," Rhonda broaches the subject that's been on her mind since they got to the beach house. Tim hadn't made up his mind about whether it was his place to enlighten her.

"What do you mean?" Tim asks, wondering how much she knows. Rhonda explains about Paul's initial anger from hearing them make love in the next bedroom, seeing him get aroused when he rubbed sunscreen on his sister and how it seemed like he was timing his lovemaking with her to his sister's moans from the next room. "I think it has something to do with their sexual hang-ups."

"You're right," Tim answers. He and Rhonda have become too close for him to lie to her. "But there is more to it than you realize." He confides in her about the overheard conversation, his follow-up discussion with Sharon and what he believes is happening at the beach house right now.

"Oh God, Tim! Paul and Sharon?" Rhonda is speechless. She thought Paul's reaction was just the natural attraction of a beautiful woman, not the result a prior incestuous relationship. Tim gives her time to digest what he's told her before he continues the discussion.

"Yeah, just like you and I," he says matter-of-factly, "except they happen to be brother and sister."

"That doesn't bother you?" Rhonda asks, still tying to get her mind around what she's hearing. Without waiting for an answer, she continues, "So all this sexual repression started from this one time in college?"

"Pretty much. I don't think their parents' teachings helped any, but it was Paul, the theology student who came up with the penance."

"Wow." Rhonda sighs, her head resting against Tim's shoulder, their naked bodies still wrapped around each other. "Since you seem to be orchestrating this, what happens next?"

"We know about them, but they don't know about us," Tim answers.

"Okaaaay," Rhonda stretches it out almost into a question. "What does that mean?"

"If today happened the way I think it did, Paul has lost a lot of his inhibitions. I think we should tell them tonight. Not together, of course, but individually with our own spouses. My instincts tell me that we should shower them with loving affection and let them know that they aren't the only ones with a secret. Then tomorrow the four of us can discuss what all of this means going forward."

"You're kidding, right?" Rhonda asks incredulously.

"I've never been more serious," Tim says, more confidently than he feels. "Think about it, Paul won't want to give up Sharon anymore than I want to give up seeing you. I think we can come to some open arrangement where everybody gets what they want."

"Damn... you really think that's how this is going to play out?" Rhonda asks, even as she's contemplating how wonderful it would be if he was right. She could keep her lover and her husband without any of the associated guilt. Of course that means she accepts her husband's incestuous relationship with his sister. It's a lot to think about.

"We can only hope," Tim says. "Come on, let's take a shower and get some lunch. The shower takes much longer than expected, in a nice way. They have a late lunch and head back towards the beach house.

"I'm nervous," Rhonda says.

"I'd be surprised if you weren't," Tim laughs. "Just follow my lead. We don't know if anything happened."

Arriving at the beach house they find Paul and Sharon sunbathing on a blanket near the water. Rhonda and Tim join them. '

"How was your day?" Tim asks Sharon as he gives her a kiss. He can't help but notice how radiant her face looks as she answers.

"Wonderful!" she winks, "How was yours?"

"The same," he answers cryptically. Sharon scrunches her brow as she tries to decipher what he means. Did he have a wonderful day or was his day the same as hers. Not in a million years.

Rhonda sits next to Paul who is lying face down and looking away from the group. She rubs some sunscreen onto his back but he doesn't acknowledge Sharon or Tim. Paul is still reeling from his marathon love making with his sister and is embarrassed to face either his wife or Tim. He especially doesn't want to face Tim because Tim already knows what's going on.

They somehow make it through the afternoon and have a semi-comfortable dinner at a local crab shack. Arriving back at the beach house, by some unspoken agreement they split into their separate bedrooms even though it's still early in the evening.

"So how did it go today?" Tim asks Sharon, taking her into his arms and kissing her passionately.

"You already know, don't you?" Sharon asks meekly. "It was just like I remembered it, Tim. But you're not surprised, are you?"

"No. It just means that you and your brother have a unique love that can't be replicated by anyone else. That doesn't diminish the love that you and I have or the love that Paul and Rhonda share. How did Paul react?"

"Oh God," Sharon almost laughs but catches herself. "When he woke up and I was... you know." Tim nods. "He must have thought I was some kind of Jezebel coming to damn him to hell for all eternity. But you were right, there was so much unfinished business and neither of us could control ourselves."

"I'm glad," Tim smiles as he watches his wife's face light up while she talks.

"Really?" Sharon asks, still surprised at her husband's reaction.

"Glad for you," he says.

"What did you and Rhonda do today?" Sharon asks, changing the subject to avoid more discussion about what her and Paul did.

"The same as you and Paul," Tim answers, watching Sharon's face for a reaction.

"What? You mean? No, you and Rhonda?" Sharon's face is a contortion of conflicting emotions.

"It started a few weeks ago," Tim says quietly. "With you and your brother doing your penance, Rhonda and I sort of commiserated over the lack of passion in our marriages. One thing led to another and..." Tim lets his voice trail off as he waits for his wife's reaction.

"Why didn't you tell me last night?" Sharon asks.

"I almost did," Tim replies. "But I didn't want it to influence what you did about you and Paul.

"You and Rhonda?" she says again. "Do you think Paul knows or suspects?"

"Rhonda is supposed to be telling him now," Tim answers. "Then tomorrow I hope the four of us can discuss what this all means.

"You honestly think we can just all share, don't you?" Sharon asks, thinking the same thing Rhonda did about how wonderful it would be if it were true. A sudden flush of color taints her cheeks as she considers the implications.

"I honestly don't know," Tim answers.

"But you told Rhonda about Paul and I?"

"She actually suspected something was weird between you two, but didn't have a clue about the actual events. I filled her in on the college stuff."

"How did she take it?" Sharon asks sheepishly. "Of course, you two having an affair probably helped with her acceptance level."

"A little, but she still has some hang-ups on the whole incest thing," Tim says.

"Yeah, well join the club. I still think it's weird and Paul is even more freaked out than I am."

"But not enough to give it up, right?" Tim asks. "You both want more of each other."

"Yes." Sharon sighs.

"I only have one more question for tonight," Tim says.

"What?"

"Did you save anything for me?" he laughs while he strips out of his clothes.

"Is that all you think about?" Sharon smiles as she starts unzipping her skirt.

In the next room, the conversation isn't going quite as smoothly.

"You actually slept with Tim?" Paul almost shrieks and Rhonda stares at the absurdity of the accusation in his eyes.

"You slept with your sister," she points out defensively. That takes the fight out of Paul and he rolls over away from her.

"Wait! I'm sorry, please don't turn away, Paul," Rhonda says grabbing his arm and pulling him back towards her. "We can talk this out." They were already both naked and under the covers before Rhonda initiated this conversation.

"Talk it out? What do you mean?" Paul asks incredulously. "Incest, adultery... let's just talk about our feelings?"

"Exactly!" Rhonda leans up on her elbow, ignoring his sarcasm. "You can't help how you feel about Sharon," she says, wondering if she actually believes it. Paul stares hesitantly into his wife's eyes. Can she actually accept how he feels about his sister?

"What about you and Tim?" he finally asks.

"Tim and I only turned to each other because... well... frankly because of the lack of passion in our lives. Like the passion you showed me last night," Rhonda smiles. Paul winces as he remembers that passion being kindled by listening to his sister's moans in the next room. Then his mind wanders to everything he and Sharon did today and his cock stirs involuntarily.

"I love you," Rhonda says, reading his face. "It doesn't matter how we get the passion going, just that we do." While she's speaking they hear subtle lovemaking noises from the next room and Rhonda moves her hand down to encircle her husband's semi-erect cock.

"This isn't right," Paul protests as his wife strokes his rapidly hardening shaft and the volume of sounds from the next room increase.

"Close your eyes," Rhonda instructs him. "Don't worry about right and wrong just now." With his sister's moans filling his head, and his wife's hot pussy sliding down over his cock, Paul accepts the inevitable. Whatever is going to happen tomorrow is beyond their concern tonight and he thrusts up into his wife's pussy as his sister's voice provide the soundtrack to his lust.

The next morning, Tim finds the conversation isn't going exactly where he wants it when Paul interrupts it with one of his typically caustic remarks.

"Is this the part where we all get naked in the hot tub together?" Paul asks sarcastically. The two couples are sitting at the breakfast table attempting to discuss their situation. Rhonda, Tim and Sharon seemed to have warmed to the idea of sharing spouses but are having trouble convincing Paul.

"Paul..." Rhonda starts to answer but Tim cuts her off.

"No, Paul's right. This is a lot to absorb." Both women look at Tim expectantly. "We're here for three more days," he leans forward to make his point. "I suggest we table this discussion until Saturday. It'll give us time to think about everything." Tim notes the disappointment on the women's faces, like they were ready for Paul's naked hot tub idea.

"What's going to change between now and Saturday?" Sharon asks.

"Well, we have three more nights. I suggest we alternate sleeping partners each night. We slept with our spouses last night, so tonight Rhonda would be with me and Sharon would be with Paul." Tim looks right at Paul to judge his reaction. "By Saturday I think we'll be ready to discuss what happens when we go home." Sharon and Rhonda turn their heads to look expectantly at Paul.

Paul felt the familiar stirrings in his groin as soon as his brother-in-law mentioned Sharon sleeping with him. Visions of their lovemaking fill his head as he stares into his sister's pleading eyes. A slight smile forms on his lips as he slowly nods his head.

"We are all depraved, you know," Paul says as the group emits a collective sigh.

Tim can hardly believe it. A week ago he was secretly having an affair with his sister-in-law and now it's all out in the open, his wife is fucking her brother and they all just agreed to swap spouses for the next three days.

Sharon is even more excited than her husband, wondering how to make the day go by faster so she and Paul can be together. But Rhonda doesn't even want to wait for nightfall. Over lunch she raises the issue of daytime sex.

"So when does the trade off actually start?" she asks while they are sitting on the deck eating sandwiches.

"What do you mean?" Tim asks.

"Well if tonight is Tim and I, is that just the night or is it like a 24 hour period? You know, could we disappear for a while this afternoon, for example?" she asks, her head cocked to the side and her eyebrows raised.

"My God, Rhonda!" Paul almost chokes on his sandwich but Sharon is anxiously awaiting Tim's answer. She never even thought of that.

"I'm just asking?" she smiles.

"Well, I guess it starts when we get up in the morning," Tim says assuming the leadership role that the group has unconsciously assigned him. "We'll alternate every 24 hours beginning whenever we get up in the morning."

"I feel like a nap after lunch. How about you?" Rhonda asks as she stands up and takes Tim's hand. Sharon watches to see how her brother will react to his wife's blatant sexual overture but he just quietly finishes his lunch while Rhonda and Tim climb the stairs. As anxious as he is to be with his sister again, he is not going to run upstairs in the middle of the day, especially with Tim and Rhonda in the next room.

While their spouses are doing who knows what in the bedroom, Sharon and Paul just cuddle on the couch downstairs. With their arms around each other and occasional bouts of passionate kissing, they acknowledge that what happened in college has never left them. Sharon tells Paul how he continued to fill her dreams and Paul admits that he has frequently relived their one night together. By the time Rhonda and Tim emerge from the bedroom a couple of hours later, Sharon and Paul, although still fully dressed, are a tangle of arms and legs on the couch and their mouths are locked together.

"Hey, get a room!" Tim jokes as they come down the stairs. "Rhonda and I are going to the beach, you guys interested?" Paul looks questioningly at Sharon as they catch their breath. She shakes her head.

"No, you two go ahead," Sharon says, never taking her eyes from her brother. As soon as they leave, Sharon starts pulling at her brother's clothes.

"Should we go upstairs?" Paul asks as he pulls his shirt over his head.

"They'll be gone a while," Sharon pants while discarding her shirt and unfastening her bra. Paul stares at her luscious breasts as she stands up to remove her shorts. Her bronzed skin from three days in the sun highlights the creamy white skin her bikini covered. Pulling her panties and shorts down together, she momentarily stands naked in front of her brother. His eyes follow her tan lines directly to her neatly trimmed blonde bush as his thick erection points towards the ceiling.

Sharon considers sucking that beautiful cock into her mouth but her pussy is too anxious. She steps forward and straddles him, sliding her well-lubricated pussy down onto his steel rod.

"Oh God! I love you, Sharon!" Paul says and then her lips silence him and her tongue darts into his warm mouth. With her knees pushed into the couch cushions and her hands gripping the back of the couch for leverage she starts rocking her hips and bouncing on her brother's cock. Paul sucks her left nipple into his mouth as his hands encircle her waist, lifting her up and slamming her back down on his hard cock.

"Oh yeah!" Sharon screams as her brother's cock sends shivers of pleasure through her sensitive pussy walls. Through the window she watches Tim and Rhonda walking down the beach holding hands and she almost laughs at the absurdity of it all. A month ago she was a frigid wife with no sex life at all and now she's fucking her brother in the living room in broad daylight with their spouses' taking a post-coital walk.

"Oh, Sharon!" Paul screams as his fingers tighten on her waist and he frantically bounces her onto his ready-to-explode cock. Sharon's breath is coming in gasps as her orgasm approaches its peak.

"Ohhhhhhaaahhhhhhhh!" Sharon moans when Paul's cock erupts inside her juicy pussy. Her release follows almost instantly and they shiver in ecstatic harmony as their lips meet in a blissfully passionate kiss.Over the next three days both couples act like sex-crazed teenagers, prone to sucking and fucking all night, changing partners each day, groping each other on the beach and taking long midday naps. Paul's enthusiasm builds and he starts fucking his wife with nearly the same intensity as he fucks his sister. Both women are eagerly sucking the mens' cocks but only Tim is eating their pussies. Neither woman has broached the subject with him. His first night with Rhonda, Tim eats her to two explosive orgasms, and then at her suggestion, fucks her in the ass. By Saturday morning whatever inhibitions any of them brought to the beach house are gone.

Rhonda wakes up before Tim and quietly slides out of bed. Seeing her clothing strewn across on the floor, she smiles at Tim's naked body and her pussy tingles as she recalls his eagerness the night before. Not wanting to wear yesterday's clothes, she decides to slip into her bedroom for clean ones. Stepping naked into the hallway she moves silently toward her and Paul's bedroom when movement in the living room catches her eye.

Glancing down over the railing, she sees Paul sit down on the couch with a cup of coffee. Rhonda assumes that Sharon must still be sleeping and trying to get her clothes might disturb her. She shrugs her shoulders and heads downstairs.

"Is there more coffee?" Rhonda asks as she comes down the stairs.

"Rhonda!" Paul whispers, "why are you naked?"

"I forgot to bring a change of clothes last night and I don't want to disturb Sharon," she smiles, bending over to kiss her husband good morning. "What are you doing?" Paul is wearing a white terrycloth bathrobe that is open to the waist.

"I couldn't sleep and I've been thinking about... you know... everything that's happened."

"Yeah, it's been crazy," Rhonda says, kneeling on the floor in front of him. "Did you come to any conclusions?" she asks as she runs her hands up the inside of his thighs. Paul's cock has reacted to his wife's nakedness and her tantalizing touch. Rhonda undoes the tie on his bathrobe and peels the sides back.

"Rhonda!" Paul hisses, "Tim or Sharon could get up any minute.

"I know, but you're already up," she smiles, her hand encircling his rapidly hardening cock. "Just one little taste?" she asks, looking him in the eyes as her tongue moves slowly up the length of his shaft.

"Mmmmmm," Paul moans as he watches his wife lick all around his hard cock, then suck his cockhead into her mouth. Before he can protest any further, Rhonda is bobbing her head up and down in his lap.

Sharon wakes up alone and makes the same decision Rhonda did about last night's clothing. Unsurprisingly she also mirror's Rhonda's idea to sneak into her bedroom for clean clothes. When she's halfway between the bedrooms she hears Paul moan and peeks over the balcony into the living room below. The couch faces away from the balcony so Paul can't see her and Rhonda isn't looking up. Sharon stifles a gasp when she sees her naked sister-in-law sucking Paul's thick cock.

Sharon backs up a step, embarrassed by what she's seen. She takes two steps towards her bedroom before she reconsiders and turns back to the railing. Leaning, forward she positions herself so just her eyes are over the railing. Sharon has never seen another couple having sex, except in videos and those are as real as televised wrestling and just as over-acted. She knows how wrong her voyeurism is, but she is totally mesmerized and can't look away and besides her pussy is heating up like crazy. Bent almost at the waist, she leans one hand on the railing as her other hand moves towards her pussy like it's on autopilot.

The sight Tim sees when he opens the bedroom door is his wife's ass rocking back and forth as she rubs her pussy while looking over the railing. Just like Paul, Tim has on a white terrycloth robe. It must be a guy thing. He walks to the railing and glances over in time to see Rhonda mounting her husband's fully erect cock.

"Peeping Tom," Tim whispers as he runs his hand down his wife's back and caresses her smooth ass cheeks. Sharon is startled but doesn't stop rubbing her pussy. She just looks at her husband and raises her eyebrows.

"Want some help?" Tim asks, pulling the tie on his bathrobe and positioning himself behind his wife's ass.

"Mmmmmm," she nods. Tim aligns his hard cock with Sharon's juicy pussy just as she pulls her fingers away. At first he gently glides it in and sighs at the hot gelatin feel of her aroused pussy but in no time he's hammering into her with enough force to make her moan a little too loudly.

"What the fuck?" Rhonda stops moving and looks up into her sister-in-law's face. "Are you spying on us?" she asks before she notices that Sharon is rapidly rocking against the railing. "Is Tim with you?" she smiles.

"Guilty," Tim responds, leaning on his wife's back and looking down over her shoulder.

"Get your asses down here!" Rhonda says.

"We're not decent," Sharon laughs, the blush rising up her neck and enveloping her cheeks.

"Exactly!" Rhonda says, "If you're watching us, then we're watching you." Sharon doesn't have an appropriate reply so she just nods. Tim pulls out of her dripping pussy and Sharon leads him downstairs with her hand wrapped around his pussy-soaked cock.

"God have mercy," Paul says when he sees his sister and her husband walking down the stairs. Rhonda starts rocking again on his cock as Paul stares at his sister's naked body.

"Rather erotic, isn't it?" Rhonda whispers to her husband as his eyes take in Sharon's taut nipples and glistening pussy lips. Sharon pushes Tim down on the other end of the couch and mounts him in much the same way that Rhonda is straddling Paul. The two couples start moving in unison as if their fucking were some kind of synchronized dance routine. They stare unashamedly at each other's undulating bodies as the orgy-like atmosphere takes their arousal to new heights.

Never in his wildest dreams did Tim imagine they all would end up like this. He couldn't have envisioned a scenario where they would even be naked in the same room together. But as Sharon rides his stiff cock, and he watches Paul suck on Rhonda's bouncing tits, he starts fantasizing about having Rhonda and Sharon in bed together.

When moans and gasps signify the telltale signs of impending orgasms, Rhonda reaches her left hand out towards Sharon. After a momentary hesitation, Sharon grasps Rhonda's hand just before their collective orgasms send them into fits of frenzy. As Paul and Tim shoot their cum into their respective wife's pussies, the two women finish out their pleasure rides with their palms clasped together in an unspoken display of unselfish solidarity and sharing.

They stay like that for several minutes, holding hands and gasping for breath until Ronda gives Sharon's hand a quick squeeze and releases it. Rolling off of Paul's cock, she collapses on the couch next to him, on the opposite side of Sharon and Tim. Sharon mirrors her movement, sitting on the couch between her husband and her brother.

"I feel like Adam who has suddenly discovered his nakedness." Paul says, embarrassed by the blatant exposure of their sweat-soaked bodies. He is particularly uncomfortable displaying his own spent cock to the group.

"Except Adam only had one woman," Rhonda teases as she leans up to kiss his cheek.

"That's right," Sharon says, leaning over to kiss his other cheek. "And you have two." Paul's face turns bright red and his cock stirs noticeably from the naked contact with his wife on one side and his sister on the other.

"Mmmm. You like this, don't you?" Sharon says, her hand automatically moving to his growing erection. When her fingers encircle Paul's damp cock, Rhonda smiles and slips her tongue to his mouth. Sharon finds this all very erotic and desperately wants to suck her brother's hard cock while Rhonda kisses him. She glances at her husband to make sure he's okay with this and notices his cock responding to the visual stimulus.

"Are you feeling left out?" she asks, reaching her other hand towards Tim's crotch. Ohmygod! Sharon's brain shouts, this is my dream! With her husband's cock in one hand and her brother's in the other, Sharon's dream morphs into reality and she lovingly strokes them both. Obviously her husband is finding this whole sharing thing very arousing and she accepts his implied consent and releases his cock to shift her body sideways on the couch. Getting up on all fours, she lowers her face to her brother's hard cock, leaving her ass waving in the air towards her husband. He caresses her smooth ass cheeks and contemplates eating her cum-filled pussy.

Paul is helplessly aroused and wonders to what level of debauchery they'll all fall, when he feel his sister's mouth close around his cockhead. Oh God! Kissing his wife while his sister is... Oh God! They are all doomed, he thinks as his hips respond and he thrusts his cock farther into his sister's mouth.

Hearing her husbands gasp, Rhonda breaks the kiss and is dumbstruck by her sister-in-laws boldness. She looks to Tim for reassurance and sees him playing with his wife's ass.

"Fuck her," she mouths to Tim when he looks up. "Fuck her ass," she mouths. Tim raises his eyebrows then pulls his legs up to kneel on the couch behind his wife. Aligning his cock with her soggy pussy, he grasps her hips as he glides it in.

"Mmmpppphhhh!" Sharon moans around Paul's cock as she bobs her head up and down. With her husband pumping into her pussy, she attacks her brother's cock with renewed vigor, dancing circles around it with her tongue. Paul moans and pulls Rhonda's lips back to his, frantically shoving his tongue into her mouth. Rhonda wants more than a kiss and feels like this may be her best opportunity to get him to eat her, while he's out of control with passion.

"I need your tongue elsewhere," she purrs as she pulls her head back and stands up on the couch. Slipping her left leg over her husband's torso, between Sharon and the back of the couch, she positions her wet pussy in front of his face and presses against his lips.

"Your tongue, Paul. I need your tongue," she whispers. The aroma is overwhelming and Paul responds like a junkie getting a fix, pushing his tongue into his wife's saturated pussy as he continues to thrust his cock into his sister's talented mouth.

Sharon is breathing through her nose, but it isn't enough. She gasps for air around her brother's thick cock but that doesn't do it either. Her husband has already ignited several mini orgasms in her enflamed pussy and she needs more air. Continuing to corkscrew her hand up and down her brother's shaft, she pulls her head up and bumps her face against Rhonda's ass cheek. What the???

At first she's perplexed as to why Rhonda's ass would be there instead of her brother's face, but it quickly dawns on her what they're doing. Ohmygod. Glancing over her shoulder at Tim, the interconnectivity of the four of them becomes apparent. Holy shit! She'd seen this on videos and thought it was totally fake. She had been certain that real people never did anything like this. Guess that was wrong.

Another quick orgasm explodes in her pussy and she lowers her mouth back to her brother's cock. Feeling his wife is sufficiently aroused; Tim licks his finger and starts toying with her puckered asshole. His fingers return to his mouth several times until he has enough saliva around Sharon's ass to lubricate his finger's entry. Pushing the tip of his middle finger into her crinkled opening, he twists and turns, corkscrewing it back and forth while he continues to fuck her pussy.

Sharon gasps when her husband starts playing with her asshole but it sends pleasure signals through her pussy and she unconsciously relaxes while she spreads her legs a little farther apart. Sucking on her brother's cock, she has a momentary flash of two cocks vying for time in her ass and pussy and she rocks back against Tim's finger when he starts pushing it in. Is this what it would feel like to be fucked by two men, she wonders.

To say that his wife's reaction surprises him would be an understatement but Tim is not one to question his good fortune. While she's in the mood, he pulls out from both holes and quickly aligns his cock with her saliva-coated asshole. Pressing his juicily lubricated cockhead into the opening, he tightens his grip on her hips and shoves his cock deep into her ass.

AgggggghhhhHHH!" Sharon cries just as her brother's cum explodes into her mouth. Her ass takes a backseat as she frantically starts swallowing her brother's cum, sucking out every drop as he jerkily shoots several more loads before settling back down on the couch. Sharon lets his spent cock plop from her mouth and braces herself against her husband's onslaught.

By this time her ass has loosened up sufficiently to be an almost pleasurable experience but Sharon misses the stimulation in her pussy. She again envisions two cocks alternating their pounding into both openings and imagines her brother in her pussy with her husband in her ass. She sighs, but without the other cock, she reaches between her legs to provide her own stimulation.

Once he's cum, Paul's brain seems to reengage and focuses on the deployment of his tongue. What is he doing? He starts to pull his head back, but Rhonda has other ideas.

"Don't stop, honey!" Rhonda pleads, smashing his face more tightly against her fiery pussy and holding it with her hands. "I'm almost there." Ronda is rocking her pussy against her husband's face trying to get his tongue to make more contact with her clit. Paul pushes his tongue deeply into his wife's pussy, thinking that's what she wants.

Rhonda rides his tongue but it's not enough. She shoves her hand down between them scratching his upper lip with her long nails as she rubs her clit towards a powerful orgasm. As she bucks her hips, her ass cheeks smack Sharon in the face and Sharon playfully bites Rhonda's ass, sending her over the top.

Quite shocked that her playful bite sent Rhonda into convulsions, Sharon returns to her own pleasure and fingers herself to a very satisfying release just as Tim starts shooting cum into her ass.

When all four of them have disentangled their limbs and are catching their breath, Tim starts to laugh.

"Well, I guess we don't really need to have our discussion about what happens when we get home, do we?" he asks, looking at the naked bodies sprawled across the couch. Both women laugh with him but all Paul can manage is a self-conscious smile.

"We still need some kind of arrangement or schedule," Rhonda says. "I travel quite often and I don't want to miss out."

"When you're out of town, do I get Paul and Tim all to myself?" Sharon teases, but her heart is pounding in her chest as she imagines the scene playing out.

"You liked having both of them, huh?" Rhonda asks. "I could get used to the four of us together, too," she smiles thinking about the pleasurable bite on her ass.

"I wouldn't mind being the recipient of the kind attention the two of you were giving Paul," Tim smiles, looking at Paul for acknowledgement of the pleasure. He just smiles sheepishly at the thought.

"I'm all for a schedule, but I know you like a little spontaneity too, Rhonda," Tim says, stretching as he gets up from the couch.

"I'm sure we can work something out," Sharon smiles as she stands up to join her husband. "But right now, we need a shower." Taking his hand, she leads Tim up the stairs as Paul watches the dimpling of her ass cheeks with each step she ascends.

"We have a couple of hours before we have to check out," Rhonda says playfully to her husband.

"Shall we join them in the shower?" he asks, surprising his wife.

"Why not just all get naked in the hot tub?" she teases but then jumps up from the couch and reaches her hand out to him before he can respond. Paul takes his wife's hand and they run upstairs to surprise Tim and Sharon. Rhonda's breasts bounce provocatively as they hurry up the steps and Paul wraps her in a tight embrace her at the top of the steps, squeezing her firm breasts against his chest.

"It's been quite a week," he says.

"That's an understatement," she smiles, kissing him before they walk toward Tim and Sharon's bedroom.
