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.
