Chapter 4091 - SISTER-IN-LAW HELPS OUT

Even though he's been married for almost a year, Tim is horny most of the time and jacks off in front of his computer quite frequently. He loves his wife. They grew up together, have always been best friends and are compatible in every way, except sex.

Tim has the libido of a healthy 26-year-old male, but unfortunately his wife, Sharon, was raised to believe that sex is dirty and disgusting, something only done as a monthly obligation. It was drilled into her, from the time she was old enough to understand; only tramps and whores enjoy sex.

In every other way Sharon is the perfect wife. They enjoy the same music and movies, they never fight and they love just hanging out together. The sexual hang-ups and inhibitions are so deeply rooted, that after a year of trying to change her, Tim has finally resigned himself to accept who she is and just enjoys her as much as he can during their monthly ritual. His frustration is compounded by the fact that she is beautiful, with a nearly perfect body.

Sharon and Tim dated in high school, and then lost contact when each left town to go to college. They resumed their relationship a couple of years ago when they both became teachers, back in their hometown. They dated for a year and Tim respected Sharon's wish to 'save herself for marriage' naturally assuming things would change after the wedding. Because he can't imagine loving anyone else, Tim has never even considered divorce. He's thought about fucking around, but the opportunity has never presented itself, at least, not the right opportunity.

As a handsome young high school teacher, Tim has his share of female students who have made it obvious they wouldn't say no, but he won't cross that boundary. That doesn't mean their nubile young bodies, with their raging hormones, don't invade his fantasies. He frequently gets himself off, imagining one or more of these sexy 18 year olds sharing his bed. But it's only a fantasy.

Surprisingly, his first real opportunity for some extra marital sex comes unexpectedly from his sister-in-law. He gets his first hint of it at a dinner party, at Sharon's parent's house.

Other than their hang ups about sex, his wife's family is generally okay. Tim and Sharon see them every Sunday at church and then have dinner once a month at their house. The dinner parties usually include Sharon's brother, Paul, and his wife, Rhonda. Paul and Rhonda have been married about two years and neither family has any kids. Not surprising to Tim, given the family's sexual hang-ups.

After dinner, the conversation generally turns to either religion or the declining sexual mores in our society. Rhonda and Tim usually sit quietly while their spouses and their parents passionately agree with each other, citing biblical references from memory as they expand on each other's ideas and pool their narrow-mindedness. For some reason, on this particular night Tim finds himself not wanting to listen to their diatribe. He excuses himself and steps out onto the deck for some air. Their discussion is so intense; they don't even notice his absence.

Standing there, leaning on the railing, Tim sucks air into his lungs as he thinks about Keisha, a beautiful, young 18-year old black student in his senior chemistry class. He closes his eyes and tries to visualize her naked body, imagining dark nipples and guessing whether her pussy is trimmed or natural. His cock stirs as he thinks about her thick lips and how they would feel...

"Mind if I join you?" His thoughts are interrupted as Rhonda steps out on the balcony and lights a cigarette. Tim moves his leg, so his sister-in-law doesn't see the bulge in his pants as they stand beside each other gazing out over the balcony, enjoying the peace and quiet.

"Not at all," he smiles.

"As hung up as they are about anything sexual, it's a wonder they ever had kids," Rhonda says, taking a drag on her cigarette and blowing the smoke out over the railing.

"I know what you mean," he laughs. "I just wish they hadn't instilled so many of their hang ups in their kids," he adds, without meaning to disclose so much.

"You too?" she asks, raising her eyebrows.

"You know, I just meant," he stutters. What did he mean?

"It's okay." She touches his arm. "I understand. Paul's a wonderful man and he treats him like a princess, but sometimes..." Her voice trails off as she shrugs and stamps out her cigarette.

"We'd better get back," she says.

Tim watches her ass sway inside her skirt as she walks ahead of him into the house. He's never thought of his sister-in-law sexually before, but he swears she's adding a little extra swish to her walk today. So her sex life isn't any more exciting than his. Interesting.

Sharon and Tim had long ago fallen into a routine of having their monthly sex after the dinner party at her parent's house. It is perfunctory sex, with no foreplay and no variety. Sharon goes into the bathroom, brushes her teeth and lubricates herself, from a tube. He's already in bed naked, when she crawls under the covers before removing her nightgown. She lies on her back and spreads her legs as he positions himself over her.

With erotic thoughts of his sister-in-law making him hard, he penetrates his wife's artificially lubricated pussy. As always, he's gentle and loving, still hoping for a reaction that never happens. As he feels her warmth envelope him, he mechanically pumps in and out while visualizing the sway of his sister-in-law's firm ass. He has a momentary flash of Rhonda's face, contorted in ecstasy, and her voice urging him to fuck her harder.

"Come on, Tim!" he hears her moan. "Fuck a woman like she needs to be fucked!" He complies with her wishes, slamming his hard cock into his wife's pussy while visualizing his sister-in-law lying under him. He vaguely hears his wife's surprised gasp as his body's urgency takes over and he drives his cock deep into her unsuspecting pussy.

He rocks faster, his chest pressed into his wife's tits and he can't help but think about Rhonda, wondering what her nipples would feel like rubbing against him. He envisions her face and lowers his mouth towards her moist lips. Before he can complete the kiss, his cock explodes, bringing him back to reality. As his hot cum spews into his wife's pussy, he notices the confused look on her face.

"I love you," he whispers as he kisses her tenderly on the lips, before disengaging his spent cock and rolling off of her.

"I love you, too," she sighs as she gets up and goes to the bathroom to shower away any evidence that they actually had sex. This is part of the ritual too, but tonight she forgets to put her nightgown back on and he is treated to the sight of her naked body as she hurries into the bathroom. His cock starts recovering immediately as he wonders how Rhonda's body compares to his wife's. Rhonda is about two years younger and from what he has seen has a killer body. He falls asleep dreaming of his sister-in-law.

Sharon lets the tears run down her cheeks as the water cascades over her body. She hates having to just lie there and not respond to Tim's lovemaking, but it's for his own protection. She can't bring him into her wickedness and curse him too! She loves him too much!

As she lathers soap over her body and his seed runs down her thighs, she continues to cry, remembering that awful night back in college, when she caused herself and her brother Paul to be cursed into damnation.

She had gone to a party with a guy she had been dating. Frustrated by his lack of progress with her sexually, he had bought a powerful sex drug from the campus pharmaceutical expert and slipped the aphrodisiac into her drink.

Paul was studying for a theology test or he'd have been at the party, too. Around midnight Sharon's boyfriend called him.

"Man, I really fucked up, Paul!" the boyfriend said.

"Where's Sharon?" Paul asked immediately, always protective of his sister.

"Man, I was just trying to loosen her up some, you know, melt her defenses a little." Paul, found out later that he had used three times the recommended dosage of the sex powder.

"Where is Sharon?" Paul yelled into the phone.

"She's out of control, man! She's dancing naked in the middle of the common room with all these guys cheering her on."

Paul ran the two blocks from the apartment he shared with his sister, to the frat house. Bursting through the door like a madman, he slammed the boyfriend against the wall, punched his face and kneed his groin, before pulling his naked sister from the room. Grabbing her dress on the way out, he didn't bother looking for her bra, shoes or panties as he led her outside. They stopped beside the house so she could get dressed.

Her drug-induced sexual arousal made it difficult for him to get her dressed. He yelled, begged and bargained with her to put her dress on. Paul was out of his mind, looking at his naked sister. This was so wrong! He kept repeating scripture to himself as he tried to get her to put her dress on.

"He hath uncovered his sister's nakedness; he shall bear his iniquity," he whispered repeatedly as her perfect breasts brushed against him when he tried to get her dress over her head. "He hath uncovered his sister's nakedness..." Sharon is not helping.

"I'm so hot, Paul," Sharon pleads. "Don't make me get dressed," she whines, while running her hands over her breasts and tweaking her hard nipples. "I'm burning up inside" she slurs, while her hands glide over her hips and she thrusts her pussy towards him. "Please make the burning stop."

"He hath uncovered his sister's nakedness; he shall bear his iniquity," Paul whispers as his cock stiffens, tenting the front of his sweatpants. Paul is aggravated, embarrassed and aroused, all at the same time. "You have to get dressed!" Paul insists. "You can't walk home naked!" Sharon abruptly pulls away from him and runs a few feet away.

"Please!" she begs as she starts swaying her hips and running her hands seductively over her body. "You have to help me, Paul," she pleads again. "Or let me go back inside," she says defiantly. Paul takes in the forbidden sight of his naked sister, his eyes lingering on the light blonde triangle of pubic hair and he can't control the reaction of his manhood.

"And if a man shall take his sister, and see her nakedness, it is a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity. Leviticus 20:17," he shouts at his sister. "Snap out of it Sharon!" he yells as he steps closer to her. "Snap out of it!" But there was no snapping her out of her drug-induced sexual arousal.

"Help me, Paul!" she pants as she throws her arms around his neck and presses her naked body against him. "I'll get dressed if you promise to help me when we get home," she whispers, while clawing his back and grinding her exposed pussy against the bulge in his pants.

Paul has always looked up to, and looked after, his older sister. He loves her like he loves no one else in the world. He doesn't know what to do. Her skin is warm to the touch and her naked lustfulness is torturing him. He has to get her home.

"Okay," he says, trying to peel her body away from his. "Now get dressed," he says, tossing her dress to her.

"Promise?" she whispers, her breasts heaving as her breath comes in gasps. Her hard nipples are jutting out towards him as he answers. Even though he knows better, he can't seem to avert his eyes.

"Yes, I promise," he answers, not sure exactly what he's promising, but just trying to get his sister dressed. In weak moments, Paul has had impure thoughts about his older sister, imagining her nakedness as he lies in bed at night. Now, here she is; standing before him, fully aroused and completely naked. His cock aches at the sight of her smooth skin in the moonlight.

Her breasts, the size of small melons, are capped with perfectly round half-dollar sized areolas and thick, taut nipples. He can't take his eyes off of her as she steps back and slips the dress over her head. Without a bra, her hard nipples poke at the thin material of the sundress.

"Come on, then!" she grabs his hand and pulls him with her as she runs to their apartment. Inside the apartment, he closes the door and she turns towards him.

"You promised," she reminds him, pulling her dress over her head and dropping it on the floor. Stepping towards him, she grabs the bottom of his shirt and tries to pull it over his head. Paul stops her, holding her wrists.

"You need to sleep this off," Paul says, letting go of his sister's arms and walking ahead of her towards her bedroom. Pulling the covers back he points to her bed. "Sleep this off and we'll talk in the morning," he says, afraid to look at the tempting sight of her mouthwatering body.

"Stay with me," she whispers. "I'm still burning up. Hold me, please," she begs as she lies down on the bed. Paul looks at his naked sister as she moves over to give him room to lie next to her.

"Just until you fall asleep," he relents, lying on his back with his arms at his sides, afraid to look at her or get too close to her warm flesh.

"Paul, the burning itch is getting worse," she says, wrapping herself around him. "It's inside me and it's like nothing I've ever felt," she says, draping her leg over his thigh and rubbing her naked pussy against his hip. "You promised to help me," she pleads, clawing at his clothes as she humps his leg. Sharon can't help her actions; her pussy is on fire and she has to quench it. She has no experience with this extreme wetness or the intense burning inside her aroused pussy.

As children, Paul and Sharon were told in no uncertain terms that masturbation is a sin and they would burn in hell if they played with themselves. Sharon took this literally and has never touched herself or let anyone else touch her. Now her insides are burning hot and wet.

"Cursed be he that lieth with his sister, the daughter of his father, or the daughter of his mother. Deuteronomy 27:22," Paul whispers as Sharon tugs at his sweat pants and he grabs her hand to stop her.

"You promised," she cries, tears streaming down her cheeks as she slips her fingers under the waistband of his pants. Paul gasps when his sister's slender fingers encircle his throbbing cock. He also took his parent's warning literally and his only transgressions have been the occasional wet dream, fueled by his impure thoughts of his older sister.

"Cursed be he that lieth with his sister..." Paul repeats, his voice shaking and his body trembling with both fear and arousal.

"Cursed be he that lieth to his sister when he promises to help her!" Sharon says, squeezing his cock while pulling at his sweat pants with her other hand. "Please! Please! Please! I can't stop the burning itch!" Sharon cries in agony. Paul can't stand to see his sister tormented and his cock is about to burst. He pushes her onto her back and pulls his shirt over his head. Hesitating, he stares at his sister's naked body as she spreads her legs invitingly.

"God forgive us, Sharon!" he says, tearing his sweat pants off and positioning himself over his sister's trembling body. "This is a sin!" he argues, making one final attempt to dissuade her as his throbbing cock probes her wet pussy lips.

"Just do it! Do it! Hurry!" Sharon pleads, pulling her brother down onto her.

Sharon gasps when Paul's hard cock penetrates her opening and enters her virgin pussy. The fire is torturous and his cock is about to provide the relief she needs. He's barely inside her and she's clawing at his back and moaning.

"Oh yes, Paul!" she cries. "More! Please! More!" she's digging at his back and spreading her legs as wide as they'll go.

The feeling of his sister's pussy closing around his cock is overwhelming to Paul. He's never felt anything like this. He pulls back slightly and plunges forward, trying to push his thick cock into her snug, virgin pussy. As slippery as she is, he frustratingly is still only halfway in. Pulling almost all the way out, he pushes her thighs wide open and thrusts his hips forward, jamming his cock deep inside her hot, wet hole.

Sharon is so aroused and out of control, that when her brother's cock breaks through her virginal barrier, the pain barely registers. She squeezes him tightly and rocks along to his awkward rhythm. Their shared inexperience does not diminish the fiery pleasure that surges through their bodies.

"Ohmygod!" she screams as her brother starts pounding into her more assuredly. Paul is oblivious to anything except the tight, hot sheath enveloping his cock. His brain has shut down and he is functioning on pure animal instinct as he starts mauling his sister's tits and kissing her lips.

"Oh Sharon!" he moans. "It's like nothing I've ever..." His voice trails off as the tension builds in his balls and his breath comes in short gasps. He's out of control, fervently slamming his cock into his sister's sizzling pussy.

"Ohhhhhhhhhhhhhhh!" Sharon screams as an orgasm unexpectedly rips through her body with a thunderous roar. She shakes and shivers, squeezing her pussy muscles around her brother's cock, triggering his release. She's never felt anything like this either.

"Aaaaarrrrrrgggghhhhh!" Paul groans as he thrusts one final time, shooting his first load of cum inside a woman's pussy. His pleasure is unknowingly intensified by the fact that his heavy load is being deposited deep inside his sister's virgin pussy. Jerking spasmodically, he spews several smaller spurts before collapsing on her soft tits.

Sweat-soaked and breathing heavily, they hold each other's trembling body, with neither of them speaking or moving. Scared and exhausted, they finally fall asleep in each other's arms; Paul's spent cock resting comfortably inside Sharon's newly deflowered pussy.

Sharon wakes up first. Her brother's naked body, entangled with hers, brings back the events of the evening before. It's all a drug filled blur, from the party to her brother reluctantly taking her virginity. She remembers feeling blissfully content at the end of it all but can't recall specific details.

"You awake?" Paul asks, not opening his eyes.

"Yes," she says quietly.

"I'm sorry," he says, trying to disengage himself from his sister's naked body.

"No!" Sharon blurts out. "It was all my fault... the party... I begged you... I remember!" she exclaims.

"You were drugged!" Paul shouts. Seeing her confused look, he explains about the aphrodisiac powder.

"I should have been stronger. We're cursed, you know," he says quietly. "Cursed be he that lieth with his sister, the daughter of his father, or the daughter of his mother. Deuteronomy 27:22," he quotes, locking eyes with her. "I'm so sorry, Sis." Tears are streaming down his cheeks and Sharon reaches over and pulls him to her, cradling his head against her naked breasts.

"What does that mean?" she asks, combing her fingers through his hair as he cries. "To be cursed, I mean."

"I'm not sure," he sniffs. "I'll have to do some research to find out what the penance is for..." he chokes back a cough, "for incest," he breathes quietly, sniffing back tears. Sharon is holding him and stroking his back. She likes the feel of his face against her breasts and her nipples respond, pushing into his cheek.

"Paul," she says, hesitantly, "how did it feel, for you?" She holds his face tightly against her taut nipple as she awaits his answers. Several minutes pass before he speaks.

"Heavenly, Sharon," he finally whispers. "No wonder it's the original sin and the ultimate temptation," he laughs nervously. "When I... um... I mean, when we... it was so... all completely consuming. It's hard to describe." They lie quietly for a minute.

"What about you?" he asks, shifting his cheek and noticing her hard nipples for the first time.

"I was pretty out of it," she admits, pushing her nipple closer to his mouth. "I remember how blissful it felt at the end; like fireworks were going off deep inside of me, shooting pleasure rockets all through my body." Her pussy is starting to send arousal signals to her now as she rocks her tits against her brother's face.

"Yeah," Paul agrees, "that pretty much sums it up." His lips brush her sensitive nipple as he speaks. "I'm so sorry," he says trying to move away from her.

"Don't," she says, pulling his face back to her tits. "We're already cursed, right?" she laughs.

"What do you mean?" he asks, wondering what she could be thinking.

"I mean, we're cursed whether we did it once or more than once, right?" she asks, her pussy anxiously wanting that blissful feeling again. She's opening and closing her legs, rubbing her thighs together.

"Sharon!" Paul exclaims, sitting up abruptly, and pulling back from her. "Do you realize what you're saying? We've sinned! We've committed incest! We're cursed!" He shakes his head, and stares at his sister's naked body, her hard nipples drawing his eyes to her firm, young tits. His cock betrays his outrage, stiffening at the sight of her glistening pussy lips surrounded by her matted pubic hair.

"If we have to do penance for something sinful, I should at least be able to remember it!" she retorts, staring at his cock as it hardens before her eyes.

"Wow! That whole thing was inside me?" she asks, moving closer to watch his cock growing more erect.

"Sharon!" he says, trying unsuccessfully to cover himself, "this isn't a game."

"I know," she says, seriously. "But you are going to spend the rest of your life worried that you took advantage of me while I was high on some aphrodisiac powder. You think this is all your fault." She reaches for his hard cock.

"We are both to blame," she continues, wrapping her fingers around his thick shaft. "We are both cursed," she says, stroking her hand up and down the length of him, "and I want to know what this feels like, before I start doing penance." She pushes him down on his back while her hand continues to stroke his cock.

"Sharon," Paul moans as his body responds to her touch. He should be strong and tell her to stop but it feels so damn good! He watches his sister's tits bounce gently as she swings her leg over him. She's right; they are already cursed.

"This was all inside of me, huh?" she asks, laughing nervously as she positions her wet pussy over his fully erect cock. "Okay, here goes," she smiles and lowers herself onto her brother's thick shaft. Paul just watches, mesmerized by how her lips stretch to accommodate his girth. When the wet heat of her labia engulfs his cockhead, he sighs heavily, leaning back and closing his eyes. Absolutely heavenly!

"Ahh! Ahhh! Ahhhhh!" Sharon moans as she pushes more and more of her brother's big beautiful cock into her enflamed pussy. It feels like nothing she's ever imagined. So full... so tantalizing... so completely beyond description. When her wet pussy lips finally touch the base of his cock, she stops moving and squeezes her vaginal muscles as she squirms around to get comfortable.

"Ohmygod! Sharon!" Paul cries, his eyes bulging at the sight of his sister impaled on his throbbing cock. He instinctively reaches for her tits, caressing and teasing as she starts rocking back and forth. All thoughts of penance are forgotten as the siblings lose themselves in the pleasure of their forbidden love.

Sharon rides him like a wild woman, bouncing so frantically on her brother's cock that she almost bounces off. Her drenched pussy flies all the way to the tip before slamming down around his shaft, sending shivers of pleasure throughout their bodies.

"Oh Paul!" she cries but her brother can't hear her over his own moans. Paul has never dreamed of anything remotely close to this. The pleasure is excruciating and he is about to burst. His sister's fiery pussy continues to assault his throbbing cock and he squeezes her tits tightly as he jerks his hips off the bed.

"Oh! Sharon!" Paul screams as she drives them both to explosive, rocket launching orgasms. She clamps her vaginal muscles around his cock as it spasms inside of her, spewing its hot liquid into her pulsating hole.

Collapsing on his chest, Sharon kisses her brother passionately as she bathes in the blissful afterglow of her release, unaware that it may be the last orgasm of her life.

Sharon spends several days trying to seduce her brother into more incestuous lovemaking but Paul refuses any further advances, admonishing her for wanting to live a sinful life.

True to his word, Paul does his research and uses the convoluted logic that has been drummed into him since childhood to arrive at the appropriate penance. Neither one of them, he explains to Sharon, can ever enjoy sex again. They can marry and fornicate for procreation but they can never again experience the blissful feelings they achieved during their incestuous sins.

They vow their penance to each other, Paul changes his major from theology to business and they never speak of it again.

When Sharon returns to her bed, Tim is sleeping peacefully. She slides in on her side of the bed, wishing that for just one night she could forgo her vow. But she is strong and unwilling to bring her curse onto her husband.

As she lies next to him, she remembers the scripture her brother cited so long ago. "If a woman profane herself by playing the whore, she shall be burnt with fire. Leviticus 21:9." He also added. "A man shall not take a wife that is a whore, or is profane. Leviticus 21:7." As she falls asleep, she renews her vow; she will not be a whore, Tim doesn't deserve to be cursed.

In the weeks following the dinner party, his sister-in-law starts occupying most of Tim's sexual fantasies. Every Sunday at church, Rhonda smiles and winks at him from across the aisle. He can't tell if it's his imagination or if she's actually flirting with him. He thinks his fantasies are making him read more into her smile than she intends. At the next family dinner, he makes sure to go out on the deck again, hoping she'll join him. Several minutes later he's not disappointed.

"How's it going?" she asks, raising her eyebrows as he lights her cigarette. "Any luck in breaking through the sexual inhibitions?" she asks without preamble.

"Uh... no," he answers, staring at her. "How about you?" The more he sees Rhonda, the more appealing she looks. Tonight she's wearing a tight skirt that shows off her firm round ass cheeks and a pull over blouse stretched across her ample tits.

"The same," she says. "He's so gentle and caring, but sometimes a girl needs more, you know?"

"Yeah," he whispers, wondering where this is going. Tim has always liked Rhonda, but they've never had a conversation like this before. Maybe she's as frustrated as he is and wants someone to confide in.

"I don't want to leave him but I don't want to live like a nun either," she says. "It's not that I don't get propositioned. I could cheat in a heartbeat, but there's no one that I'm interested in or trust enough..." Her voice trails off.

"I know what you mean," he tells her, his cock stirring at the possibilities that this conversation provides. She looks up at him, just staring, like she's making up her mind about something.

"I've seen you watching me in church," she says, moving closer to him. "You don't look like you're thinking sacred thoughts."

"I'm not," he answers, looking down at her as she stands inches from him. Her breasts swell against the fabric of her blouse when she takes a deep breath.

"Maybe we could help each other, you know, and keep it in the family," she blurts out, reaching her hand out towards his waist. He nervously jumps back and looks around to make sure no one else is here.

"Don't worry," she laughs. "I'm not going to attack you out here." Reaching out again, she unclips his cell phone from his belt. "I just want to program my number into your phone," she says, flipping it open and punching numbers. "This is for my company Blackberry. It's on twenty-four seven and I'm the only one who can retrieve the messages. Text me if you want to get together." She smiles and hands him back his phone just as Sharon and Paul walk out onto the deck.

That night as he fucks his wife's unresponsive pussy, Tim can't stop thinking about his sister-in-law. As he rams his cock faster, he remembers the curve of Rhonda's breasts and imagines sucking on her aroused nipples. He starts pounding harder as he recalls the swaying of her round ass cheeks and fantasizes cupping his hands around them, digging his fingers into her soft flesh. She's actually invited him to cheat with her! A sudden burst of moist heat emanating from his wife's pussy shocks him out of his fantasy and his cock erupts with a more intense orgasm than he's had in a long time. He stares into her face as he catches his breath, looking for some small sign of pleasure.

"You're starting to get a little rough, aren't you?" she asks, pushing him off of her and grabbing her nightgown as she heads into the bathroom. He doesn't even bother to watch.

While his wife's in the shower, Tim grabs his cell phone off the dresser and sends Rhonda a text message.

He learns that Rhonda will be out of town for two weeks and they arrange to get together when she gets back. The time drags by and Tim starts second guessing his decision. Should he really be cheating on his wife? Is Rhonda the right choice? What if they get caught? His indecision morphs into lustful fantasy and by the time Rhonda gets back in town he can barely wait to push his cock into a responsive pussy.

They arrange to meet at an apartment that Rhonda's company uses for out of town guests. Rhonda is a lawyer and they frequently have clients who need a place to stay. It's cheaper to maintain an apartment than to pay for hotels. Of course, they bill the client the same as if they stayed at a four star hotel. He tells his wife that he's taking on a tutoring assignment and will be late on Wednesday afternoons. Rhonda has no trouble getting away and they arrange a time for the following Wednesday.

Rhonda answers on the first knock and Tim stands there for a second until she reaches for his hand and pulls him into the room. As soon as the door is closed, Rhonda wraps her arms around his neck and presses her lips to his. The kiss is urgent and hungry as their tongues fight for space in each other's mouth and their clothes begin to collect in a heap on the floor.

They somehow make it to the bed, coupling like animals. Her pussy is on fire, drenched like a flash flood after a long draught. His cock fires like a repeating rifle, hardening again and again as she demands more fervent pounding. They barely speak. They just fuck all afternoon, both of them releasing months of pent up sexual tension.

They start out fucking face to face with Tim pushing Rhonda's legs over her head as he jackhammers into her underused pussy. Then she turns around and he fucks her from behind, holding her hips and admiring her sweet ass cheeks as he slams his throbbing cock into her hungry pussy. Finally, after sucking him hard again, Rhonda sits astride his cock and rides him like it's the last fucking she'll ever get. By the end of the afternoon, they're just two spent bodies, lying in a tangle of sheets and sweat, trying to catch their breath.

"God! I needed that!" she sighs. No kidding!

"That was incredible!" he answers, leaning over her and kissing her lips. "I haven't had a blowjob since college," he tells her, kissing her neck and moving his lips towards her gorgeous tits.

"I haven't had a cock in my mouth for probably as long," she smiles. "Next time, I'm going to suck you until you cum but this time my pussy just needed too much attention." That's an understatement but Tim's not complaining, especially since she mentioned a next time.

"Come on. Let's take a shower," Rhonda says, pushing his mouth away from her thick nipples.

"I have to go home and make dinner."

They lather each other in the shower and Tim takes his time exploring her curves with his hands while she strokes his cock and caresses his balls. Her tits are firm and her nipples, surrounded by large, rose-colored areolas, respond instantly to his teasing. By the time they rinse off, he's rock hard again.

"I guess I really don't have to wait for next time," Rhonda smiles as she kneels on the shower floor and slides her lips down his rigid shaft.

Oh God! He's fantasized this exact moment so many times that it feels like it's already happened. After fucking all afternoon, he's surprised he has anything left but as she licks his cock and caresses his balls he feels the tension build again. Her tongue is swirling around his cockhead as her hand pumps him in and out between her moist lips. Goddamn! He grabs her shoulder length hair and thrusts his cock into her mouth. Only her hand, wrapped loosely around the base of his cock, keeps him from gagging her.

"Ohhhhhhh! So fucking good!" he moans as she caresses his balls. The intense pleasure is overwhelming and without warning he abruptly starts cumming inside his sister-in-law's mouth.

"Aaaarrrrrgggghhhhhh!" he groans, shooting more cum than he imagined he would have left. Balancing himself with one hand against the tile wall, he convulses against Rhonda's moist lips while she sucks and swallows until he's drained of every drop.

"Thank you, Tim," she says, when they're fully dressed. She's thanking him? He takes her in his arms and tenderly kisses her lips, momentarily reigniting their lust.

"I told Sharon that I have to tutor on Wednesday afternoons," he tells her, reluctantly breaking the kiss to let her know that they could do this every week.

"Mmmm. Tutoring sounds good. I'm glad we're keeping it in the family," she laughs as they leave the apartment. His mind replays this afternoon several times that night and all through the next week but it all seems a blur. Everything happened so fast that he didn't get a chance to savor it. Next time will be slower and more deliberate. God, he can't wait to see her again.

Rhonda apparently feels the same way because when she opens the door the following Wednesday, she's stark naked!

"I figured why waste time," she smiles as she closes the door and starts unbuttoning his shirt.

"Why indeed!" he exclaims as he grabs her bare shoulders and holds her at arms length. "You look delicious!" he tells her and his eyes roam over her body, trying to take in everything at once; her firm tits, her flat stomach and the neatly trimmed triangle of light brown hair covering her pussy mound. She has long slender legs and he slowly turns her around to admire her from the back. When his eyes feast on her gorgeous ass, he lets out an appreciative whistle.

"You're embarrassing me!" she laughs, pushing his hands from her shoulders and turning back around to finish undressing him. "Did you mean what you said about me looking delicious?" she asks, raising an eyebrow as she pushes his pants down to his ankles.

"I can't wait to find out just how delicious," he answers, kicking off his shoes and stepping out of his pants. When he's completely naked she wraps her arms around his neck and presses her body against him.

"I was hoping you'd say that!" she whispers, nibbling on his ear. "I can't remember the last time anyone's had his tongue in me. I'm soaking wet just thinking about it," she breathes, taking his hand and leading him into the bedroom.

"Probably as long as it's been since I've tasted a woman's charms," he answers, following anxiously. When they first got married he tried to get Sharon to let him eat her pussy but she thought it was the most disgusting thing she'd ever heard of so he backed off. Now he's about to taste his sister-in-law's sweet nectar. His cock is fully erect and throbbing with anticipation.

"I like that," she says quietly as she crawls onto the bed and lies on her back. "Tasting a woman's charms. Very poetic," she smiles and spreads her legs invitingly.

"Wow!" he whispers as he positions himself between her legs. "You really are wet." Her thighs are wide apart and her pussy lips are glistening with moisture. He breathes deeply through his nose, drawing in her womanly aroma. Fuck! It's like an intoxicant, getting him high on the smell of her dripping pussy. Even though she doesn't need much teasing, he licks all around her pussy anyway, avoiding her slick labia for now.

"Mmmmmm," she moans, wiggling around and trying to get his tongue to make contact with her pussy lips. Finally, he leans his face directly over her splayed open pussy and takes one long lick from the bottom of her slit to the top of her clit. The taste, mixed with her aroma, is fucking incredible and he feels like he could almost cum just eating her.

"Oh yeah! Oh Tim!" she moans as he gently sucks one of her pussy lips into his mouth. Swirling his tongue all around it, he lightly nibbles on it before moving to the other one and sucking it in his mouth.

"Oh God! That feels so good!" she sighs. He slides his arms behind her knees, lifting her legs to give him better access to her juicy opening. Slipping his tongue between her wet lips, he laps up her juices and tongue fucks her anxious pussy.

"Oh! Tim! Oh! Fuck!" she cries as he slides his tongue in and out of her slippery hole. She is soaking wet and her juices are coating his mouth and cheeks as he move his head from side to side. Rhonda is thrashing around on the bed, grabbing his hair and humping her steamy pussy against his mouth.

"Oh God! Yes!" Rhonda exclaims as he moves his tongue up to lick the top of her slit, just below her clit. Slipping two fingers into her pussy, he pumps them in and out and lightly flicks his tongue across her exposed clit. By the time he sucks her clit into his mouth, she's nearly hysterical.

"Ohhhhhhhhh! Fuck!" Rhonda's moaning and twisting her body around, humping his fingers and pushing her clit against his mouth. "Don't stop! I'm cumming, Tim! Don't fucking stop!"

She's holding his head while bucking her pussy feverishly against his mouth. He keeps sucking her clit, trying to keep it in his mouth as she writhes around on the bed. Just as he thinks he can't stay with her, she clamps her pussy muscles around his fingers and lets out a loud moan.

"Aaaaarrrrrrrgggggghhhhhhhhh!" she screams, mashing his head tightly against her pussy as she shakes and shivers through her orgasm. When she finally releases the pressure on the back of his head, he starts lapping up her sweet, delicious pussy juice. Fuck! It's been so long and it tastes so good that he just keeps licking her juices and eating her pussy until she starts rocking against his mouth again.

Once more, using his fingers on her pussy, he sucks on her clit and he eats her through another intense orgasm. This time she's even more frantic, squirming all over the bed, grabbing his hair and grinding her pussy into his face until he can hardly breathe. When she finally cums, it's like someone opened the fucking floodgates; pussy juice is gushing all over his face and running down his chin.

Before she even catches her breath, he moves up her body, trailing kisses across her stomach, nibbling her erect nipples and positioning his hard cock at the entrance to her womanhood. Pushing his pussy-soaked tongue in her mouth, he glides his cock into her welcoming pussy, rocking gently until he's completely buried in her steamy hole. The moist heat surrounding his cock sends shivers through his body as her hot velvet walls tighten around him.

Fuck! She feels so good! His tongue explores her mouth as he slowly withdraws his cock until just the head is resting between her moist lips. With one quick thrust, he slams back in and his balls slap against her ass cheeks. He presses his cock into her, not moving it as her pussy quivers around him."Oh! God! Tim!" she breaks the kiss and he feels her shudder beneath him, her pussy spasming around his motionless cock. "I've never had so many..." she doesn't finish because he's started rapidly pumping his cock in and out of her hot pussy.

"Oh yeah! Oh! Tim!" She wraps her arms and legs tightly around him as he pummels her soggy hole. His cock is aching for release now and he pounds harder and faster, driving them both into a sweat-soaked frenzy.

"Ohmygod! Ohhhhhh! Fuck!" Rhonda tightens her arms around him, digging her nails into the middle of his back. He feels her legs loosen from his sides as she plants her feet on the bed and thrusts her hips up to meet his quickening strokes. They're both in a delirious state, slamming against each other as their pleasure builds to a raw peak.

"Ohhhhhhhhh!! Yeeeeeeessss!" Rhonda claws his back and squeezes her pussy muscles around his cock as she shudders through another cock-drenching orgasm. Tim doesn't even try to hold back, plunging into her one final time, his cock erupts deep inside her pulsating pussy. He jerkily shoots several more spurts into her quivering hole before collapsing on her fleshy tits and pressing his lips to hers.

They kiss passionately while their bodies shiver and shake through the after throes of their heat-crazed lovemaking. For a few blissful minutes, no one else exists in the world except the two of them.

"I've never..." she whispers, still catching her breath.

"Me neither," he answers, kissing her again as his cock stirs inside her pussy. She smiles at him questioningly while raising her eyebrows with a look of incredulity.

"It's what you do to me," he answers and starts moving inside of her.

"Stop," she pleads, gently pushing him off of her, "you're going to wear me out." He reluctantly withdraws his recovering cock from the warm sheath of her cum-filled pussy.

"Besides," she smiles, "I haven't tasted you today." She rolls him onto his back and rises up on her knees beside him. Wrapping her hand around his semi-erect cock, she stretches her tongue out and starts licking her juices from around his cockhead.

"God, Rhonda!" he breathes as she moves between his legs and feeds his rapidly recovering cock into her warm mouth. Sliding her lips halfway down the length of him, she flicks her tongue against the sensitive underside. Fuck! He can't remember being more aroused or more pleasured than he is right now. Rhonda sucks on the head of his cock while corkscrewing her hand up and down his slick shaft.

Tim closes his eyes and lays his head back as Rhonda bobs her head up and down and caresses his balls. Her hard nipples brush against his thighs as her very talented tongue dances around his cock. It's too much and he feels the tension building rapidly.

Tim reaches for Rhonda's head, entwining his fingers in her hair as he starts bucking his ass off the bed. Their eyes meet and she pumps his cock in rapid-fire motion with her lips wrapped around the head and her fingers stroking his balls. That's it. He fucks his cock into his sister-in-law's mouth, spewing cum that she urgently gulps down while he holds her head in place. She sucks and swallows until he's completely drained and he falls back on the bed, panting as his head hits the soft pillow.

"Fuck! Rhonda!" he sighs, "that was fucking incredible." She's still slurping his cock, licking the last remnants of cum off the sides.

"I enjoyed it too," she says, crawling up beside him and draping her arm over his chest. "How many times can you cum in a row?" she asks, while cuddling up to his side.

"I don't know," he answers honestly, "I've never really had a chance to find out."

"We'll have to test you," she says matter-of-factly as she brushes her fingers through his chest hair.

"I like the way you think," he responds, putting his arm around her shoulder and pulling her closer to him.

"Mmmmm," she sighs. "I think we better shower, before I fall asleep and miss dinner."

"Yeah," he answers, looking at the clock. "Rhonda, there aren't words to express..." She cuts him off before he can finish.

"Shhh," she says, putting her fingers to his lips. "I know," she whispers, "believe me, I know."

Leaning up, she kisses him hard on the lips. Halfway through the kiss, she swings her legs over his body and stretches out on top of him, mashing her soft tits against his chest and grinding her matted pussy mound against his spent cock.

"We deserve this," she says, breaking the kiss. "We've nothing to feel guilty about." He just nods and pulls her face back down to his. What an incredible woman!

The following evening, there's another family dinner. It's the first time Tim's been in the same room with Rhonda and Sharon since he and Rhonda became lovers. He struggles to maintain his composure all through dinner, barely engaging in any conversation. As soon as he can, he heads for the sanctum of the back deck. Rhonda joins him moments later.

"You all right?" she laughs. "You looked as stiff as a board in there," she says, walking towards him but not taking out her customary cigarette.

"I'm fine," he answers. "Don't you find it awkward or weird?" he asks, leaning against the railing and admiring the way her tight jeans show off her figure.

"Of course it's awkward," she says, stopping next to him and looking over her shoulder into the dining room window. "You can see all four of them from here, can't you?" she asks quietly.

"Yes," he answers, confused by her question.

"Good," she says, squatting down and moving over in front of him. "Tell me if any of them start to come out here," she says, tugging at his zipper.

"Rhonda!" he hisses in a hushed whisper. "What do you think you're doing?" He's nearly freaking out but his cock is already at attention. Rhonda's head is below the windowsill and Tim realizes that while he leans against the railing looking into the house, they can't see her at all.

"This is better than a cigarette, any day," she smiles up at him as her hand gropes around inside his fly. Maneuvering it through his boxers, she releases his hard cock to the air. "Speaking of stiff as a board," she laughs and deftly swipes her tongue across the tip of his cock.

"Oh fuck!" Tim whispers. "I can't believe you're doing this." He wants to close his eyes and savor the feeling of Rhonda's tongue swirling around his cockhead but he keeps them glued on his wife and in-laws, sitting around the dining room table.

Rhonda rapidly pumps Tim's cock in and out of her mouth while her tongue slithers all around its most sensitive areas. Tim is trying to act normal and look like nothing is going on when what he really wants to do is grab Rhonda's head and fuck her warm mouth like he did yesterday.

Rhonda's sexuality has been reawakened by her encounters with her brother-in-law. She loves the sensuous feel of his hard cock in her mouth and the salty taste of his cum. She would like to take her time and prolong the pleasure but she knows she better make this fast. Her expert tongue, coupled with the risk-taking thrill of doing this out in the open, has Tim ready to shoot his load in minutes.

"Fuck, Rhonda!" he breathes, closing his eyes momentarily as his cock swells and Rhonda pumps faster. Blasting a heavy load of cum into her mouth, he opens his eyes and panics when he doesn't see Sharon sitting at the table.

"FUCK!" he whispers, glancing all around. "Sharon's not there!" he hisses, trying to push Rhonda's mouth away from his cock as his eyes search the room for his wife. Rhonda hangs on, keeping her lips around the end of his cock until the last little spurt is out.

"Turn around and tuck it in," Rhonda orders as she springs to her feet and stands next to him, blocking the view of anyone coming through the door. "Been saving that up, have you?" she whispers, squeezing his ass cheek and licking the last bit of cum from around her mouth just as the sliding glass door opens. To innocent eyes, they look like two normal people admiring the view.

"Here they are!" Sharon says, leading her brother out onto the deck. "We always seem to lose you two," she smiles.

"I bet you hardly missed us," Tim says, turning around to face his wife with his pants looking perfectly normal. He catches Rhonda's eye and wipes his cheek, hoping she'll take the hint and clean off the dab of cum clinging to her dimple. She gets it just in time as her husband walks up next to her. Fuck that was close. Tim breathes a sigh of relief.

"Oh, I know how you feel about those discussions," Sharon laughs as she changes the subject and asks the group how they feel about renting a beach house together for a week this summer. Rhonda says she's all for it, smiling at Tim and almost imperceptibly raising one eyebrow. They all agree it's a great idea and Rhonda and Sharon arrange to have lunch next week to discuss the details.

At home in bed and still reeling from the impromptu blowjob at his in-law's house, Tim plunges his hard cock into his wife's gel-lubricated pussy. Mentally reliving the feel of Rhonda's tongue swirling around his cock, he thrusts into his wife with unprecedented vigor. Her lack of response is obliterated by the images in his head as he recalls the two recent rendezvous with his sister-in-law and the taste and aroma of her fervently aroused pussy.

Sharon doesn't know what's gotten into Tim lately but she's finding it harder and harder to control herself during his passionate lovemaking. Her body is fighting her brain as her insides warm to his forceful pounding, emanating natural lubricant and unfamiliar arousal. She tries to think of something to force her brain to respond. She focuses on their vacation and her lunch next week with Rhonda. As her juices ooze around her husband's jackhammering cock, she holds perfectly still and wonders about Paul and Rhonda's lovemaking.

Tim feels his wife's pussy responding like never before. The heat and moisture engulfing his cock drives him to speed up his rhythm and try to increase Sharon's pleasure. Rising up on his arms, he looks at his wife's face as he continues to slam his cock into her steaming pussy. Her face is contorted into a level of concentration that he's never seen before. She's fighting it! He can't believe it! He's giving her the chance for a real orgasm, probably her first, and she's fighting it. What the fuck!

He thrusts into her one final time, erupting in a flow of cum deep inside her begrudgingly responsive pussy. He doesn't get it and doesn't know what to do about it as he collapses on her chest.

"You really need to be more gentle, Tim," she whispers, releasing the breath she's been holding throughout his final thrusts. She kisses his lips and gently rolls him off of her. Ignoring her nightgown, she walks naked into the bathroom and starts the shower. Adjusting the water temperature, she steps under the spray and immediately sinks to the floor with her head buried in her hands. What is she going to do? Maybe she should talk to Rhonda.

When Tim shows up at Rhonda's apartment on Wednesday, she's wearing a white babydoll nightie without any panties. He marvels at the way the sheer material drapes over her erect nipples and hangs just below her triangular patch of hair. He's amazed at how being almost nude is even sexier than being completely naked.

"Guess what I've got," she says, with her hands behind her back. He closes the door before he answers.

"I can see what you've got," he says, grasping her soft tits in his hands and feeling her taut nipples press through the thin material into his palms.

"Not those," she laughs, bringing her right hand up and showing him a small box of cards.

"This!" The box reads, "Sex Deck: Playful positions to spice up your love life".

"There are fifty cards with fifty different positions," she says triumphantly, "and we're going to try them all." She wraps her arms around his neck and grinds her pussy against the bulge in his pants. Sliding his hands under the back of her babydoll, he cups her bare ass cheeks as he pulls her against him.

"What did I do to deserve you?" he asks, digging his fingers into her fleshy ass cheeks. God! She feels so fucking good. He could squeeze her ass forever!

"You don't deserve me," she teases, "but we're family!" Rhonda laughs as she breaks away and spreads the cards out on the bed. She's bending over, mixing up the cards and the babydoll nightie rides up above her ass cheeks.

"Where do we start?" he asks, staring at her perfect ass while pulling off his shoes and socks.

"Pick a card, any card," she smiles, pointing to the bed. "I figure we can start by each picking one card and then alternating until we're exhausted." She's excitedly bouncing up and down on the balls of her feet and he enjoys the lively spring of her tits, clearly visible through the sheer material. Reaching over to the bed, he picks a card.

"The reverse cowgirl," he says, reading the card. Rhonda's tits are pressed against his arm as she reads over his shoulder. A guy is pictured lying on his back with a woman facing his feet as she straddles his cock.

"Oooo, ride 'em cowgirl. I'm getting wet just imagining how that feels," Rhonda says.

"Aren't you always wet?" Tim asks playfully as he runs his hand up her inner thigh and across her moist pussy lips.

"When I'm around you," she sighs, turning towards the bed. "My turn to choose." She picks a card from the far side of the bed. "Suspended congress position," Rhonda reads. "I'm not sure about this one," she smiles, handing him the card. "Do you think you can do it?"

He looks at the picture. This time the guy is standing and the girl has her arms and legs wrapped around him while she's impaled on his cock. His arms are behind her back holding her up as she apparently bounces up and down on his cock.

"The fine print says it might be easier to maintain thrusts if the woman has her back to a wall, like in a shower," he tells her. "Maybe we should start out that way and see if I can move away from the wall. Let's do mine first," he suggests, "and then try yours in the shower."

"Okay. Let's get you naked!" Rhonda says, attacking the buttons on his shirt.

"The cards are an awesome idea," he tells her. "What made you think of it?"

"I've always been fascinated by the sex position books and wondered if there could really be that many different ways," she smiles as she drops his shirt on a chair and starts unfastening his belt.

"If this works out, there's a book called 365 Sex Positions - A Year of Great Sex," she teases as she pulls his pants and boxer shorts down together, releasing his hard cock. Rhonda kisses the tip of his cock, flicking her tongue against it, before standing up and wrapping her arms around his neck.

"We can use the cards to find out how many times you can cum," she smiles. Rhonda pushes him down on the bed and takes a step back. She starts rhythmically swaying from side to side while teasingly pulling up the bottom of the sheer babydoll. Smiling at his cock's instant reaction, she dances erotically and slowly removes her nightie.

"You are so beautiful," Tim sighs as Rhonda tosses the nightie aside and climbs up on the bed.

"I know I am!" she smiles over her shoulder while turning to straddle his legs, "Ready?"

"I think I'm going to like this," he says, admiring her sensational ass again while she positions herself over his stiff cock. He uses his hand to push his erection into a more upright position and slides it between her pussy lips as she lowers herself down.

"Mmmmm," he moans when her hot pussy glides down around his hard cock. Rhonda leans forward, placing her hands on his knees and forcing his cock to bend with her.

"This is really different," he says as her pussy grips his cock and she starts moving up and down.

"Feels awesome!" he adds, grabbing her hips and trying to speed up her motions.

"This feels sooo good!" she answers and starts rocking faster. He tries to thrust into her but her weight keeps him from moving very much and he finally just lies back and enjoys her being in control.

The position is absolutely wicked. Not only is she moving up and down, she's undulating her hips and stimulating his cock in a way he's never experienced.

Rhonda leans farther forward, gripping his ankles and grinding her clit against him as she rocks faster. Her widespread ass cheeks give him a clear view of his glistening cock disappearing between her wet pussy lips. This position also affords him a great view of her puckered asshole and he moves one hand from her hips to run a finger around the crinkled opening.

"Ohhhh Yeah!" Rhonda moans while glancing back over her shoulder. "Play with my ass," she pleads.

"That wasn't on the card," he teases as he sticks his index finger in his mouth, moistening it with a thick coating of saliva before moving it towards her asshole. Twisting it around to lubricate the opening, he tries to gently push it in but she's bouncing too rapidly.

"Stop moving a second," he tells her and she sits firmly down on his cock, panting as he corkscrews his finger into her ass.

"Mmmmmmm!" she moans, wiggling her ass against his finger, which titillates his cock and buries it deeper inside her hot pussy. With his finger about halfway into her ass, she starts moving again, riding his cock harder and faster than before. Her asshole is tight and he twists and turns his finger rather than trying to pump it in and out as she pistons up and down on his hard cock.

"Fuck! I'm about to cum!" he declares. Rhonda's gyrations on his cock, and the excitement of fingering her asshole, have pushed him to the peak of arousal. The way she's moving and panting, she can't be far behind him. His finger now easily slides in and out of her ass.

"Oh! Fuucck!" he moans, tensing his legs as his orgasm builds. Again, his attempts to thrust up into her are thwarted by her weight on his legs.

"Hang on, Tim!" she cries. "I'm almost there. I'm so damn close!" she begs and he tries not to shoot his load. While she increases the urgency of her thrusts and slams down harder on his sensitive cock, he jams his finger deeper into her asshole.

"I can't hold back!" he shouts as the first load of cum blasts from his cock. He spasms beneath her but she just rides harder while he spews his cum into her fiery pussy.

"Ohhhhhh! Fuuuuuuuuccccck!" Rhonda screams, slamming down hard on his nearly spent cock. Squeezing her pussy muscles around him, she jerks upright and sits fully erect. He pulls his finger out as her orgasm rips through her body. Grabbing her hips, he holds onto her as she convulses through the multiple shockwaves surging from her quivering pussy.

"And that's only the first card," Rhonda says, trying to catch her breath as she disengages herself from his cock.

"Lucky me," he smiles. "Forty-nine cards to go!" She flips around and is lying with her head on his chest. Draping one leg over his, she cuddles into his shoulder as he wraps his arm around her.

"Think we'll live through them all?" she asks, her breath still coming in gasps.

"If not, I can't think of a better way to die," he laughs.

"I really liked your finger in my ass," she says. "I've never done that before."

"Wow! You fooled me!" he says. "The way you commanded me to play with your ass I thought this was a regular occurrence."

"Some of the cards are for anal sex positions and I want to be ready when we draw one," she says quietly. Fuck! Anal sex with his sister-in-law! Of course, he's heard about it and seen porn videos but he never thought he'd get to try it.

"Have you ever done it?" she asks, when he doesn't respond.

"No," he answers, "but I've always wondered what it would be like."

"Well, play your cards right..." she laughs and leans her head up to kiss him.

The standing position in the shower doesn't go as well as the reverse cowgirl but they manage to both get off and he does enjoy being face to face while they're fucking.

Afterwards, they dry off and just lie on the bed, talking.

"Sharon asked some weird questions at lunch today," Rhonda tells him.

"What kind of weird questions?" Tim asks nervously.

"Oh, she doesn't suspect anything," she reassures him. "She was more interested in Paul and I?"

"What do you mean?"

"Well, it's not like she came right out and asked but she seemed very interested in how Paul and I are doing sexually," Rhonda says. "It was weird, because we used to have these girl talks before either of us got married but we haven't in a long time."

"I've noticed a slight change at home," Tim confides. He explains how he's felt Sharon starting to respond during their monthly ritual but seemingly trying to fight it. Rhonda can't believe it when he tells her how Sharon uses a lubricant.

"With your tongue at her disposal?" she says, flicking her tongue out for emphasis. "She's an idiot!"

"So, what did you tell her?" he asks.

"She was pretty interested in how her family's religious beliefs affected me in the bedroom and I thought maybe if she knew Paul didn't buy into all that crap she might, you know, loosen up a little." Rhonda is running her hand across Tim's stomach as she speaks.

"I lied," she says, matter-of-factly. "I told her that her brother was an amazingly passionate and sensitive lover who took me to places I couldn't even describe," Rhonda laughs. "You should have seen the look on her face when I told her that what he does with his tongue was downright sinful." Rhonda's hand is combing through Tim's pubic hair as she continues more seriously.

"If she only knew I was describing you," she sighs, her hand sliding between his legs and gently caressing his balls.

"What did Sharon say?" Tim asks, spreading his legs to give Rhonda more access while not even trying to hide his fascination with the sexual discussion between his lover and his wife.

"That's what's weird," Rhonda says, still stroking his balls. "Her face got red and... at first, I thought I had embarrassed her but then I realized she looked really angry. She quickly changed the subject and then said she had to go." Tim thinks about the conversation while enjoying the way Rhonda is fondling his balls. His cock is coming to life from her teasing.

"I can't imagine why she would be angry about you and Paul," he says, almost to himself. "Unless she feels like it somehow betrays their parent's beliefs."

"Do you thing she'll stop resisting her own feelings if she thinks her brother has abandoned the fold?" Rhonda asks.

"I don't know but I appreciate you trying to help," he says, kissing the top of her head.

"Tim," Rhonda says, "if Sharon starts responding to you... will we still...?" She doesn't finish.

"Oh, Rhonda, no," Tim answers honestly, his cock now standing at attention. "I can't imagine stopping this. What you do to me..." His voice trails off.

"What we do to each other," she says with a mischievous grin on her face. "Speaking of which..." she smiles as she licks her way down his body, dragging her soft tits across his cock, before sucking the head of it between her lips.

In no time at all Rhonda is bobbing her head up and down on his hard cock as her fingers continue to tease his balls. He thrusts up into her mouth, not even trying to hold back and explodes with his third orgasm of the afternoon.

"We aren't even close to finding out how many times you can cum," Rhonda says as they get dressed. "We need more time."

"Once schools out, I have a couple of weeks before summer school starts. We could spend the whole day," he tells her as she runs a brush through her hair.

"Let's plan on that," she says, smiling at him in the mirror. "And of course, we're going to spend a week together at the beach," she adds, mischievously.

"With our spouses," he reminds her. She just shrugs and kisses him on the lips.

Before they leave, Rhonda suggests they draw cards for next week so they know what to look forward to. He agrees and draws a Doggy Style card from the box. The picture is just what you would expect with the woman on all fours and the man penetrating her from behind. He was hoping for something more exotic, before it dawns on him that just fucking Rhonda every week is exotic.

Rhonda draws a Missionary Anal position card. Now we're talking! The woman is on her back with her legs drawn up next to her head and a pillow under her hips while the man half kneels between her legs, penetrating her ass with his cock.

"You look happy about fucking my ass!" Rhonda teases as she playfully squeezes his cock. He didn't realize he was getting aroused again.

"Should we bring some lubricant?" he asks. "I've never done this before."

"You can get some just in case, but first we'll try using some natural lubricant," she laughs at the puzzled look on his face. "I'm sure you can churn up some lubricating juice with your tongue in the right place, can't you?" she asks.

"No doubt!" he says, kissing her again before they exit the apartment.

Sharon is fuming! Ever since her lunch with Rhonda, she's been pacing the floor and trying to figure out how her brother could betray her like this. The hypocritical bastard was sucking and fucking his wife into oblivion, while Sharon was gritting her teeth and trying not to have an orgasm because of the vow they took! The vow to never enjoy sex again! Doesn't that mean no orgasms?

What the hell was she thinking? How could she have been so stupid? Women can have sex without climaxing but men never do! While she's sacrificing her sex life with her husband, her brother is getting off with his wife all the time, according to Rhonda.

Rhonda's description of their lovemaking brings back vivid images of the day she was gyrating on her brother's hard cock. The only orgasm she's ever had, at least when she was fully lucid. She doesn't want to think about that! Pounding her fist against her leg, not for the first time, she tries to make sense of it all. How could her brother have deceived her like this?

She needs to calm down and label her feelings. That's what all the self-help books say; label your feelings. Okay, there is anger, of course, and betrayal, frustration, hurt, jealousy. Jealousy?

Of what? Of who? Of Rhonda? Because she's getting orgasms that Sharon's not or... no! She is not jealous of her brother's wife! No! That's not what this is about. She hears Tim's car in the driveway and tries to pull herself together.

"How was your day?" Tim asks, walking into the kitchen where Sharon is making dinner.

"Fine. And yours?" she asks, smiling over her shoulder at him.

"Great!" he says, trying not to sound too enthusiastic. It really was a great day, eating and fucking his sister-in-law. "How was your lunch with Rhonda?" he asks, wondering how Sharon will react.

"Good," she says, not very convincingly.

"Did you guys agree on a date for our joint vacation?" he asks, already knowing the answer from Rhonda.

"Yes," she says, hesitantly. "Fourth of July week," she answers, turning from the stove. "Do you really want to do this? Would you rather take a vacation somewhere, just the two of us?"

"I thought this was your idea," Tim answers, wondering how her lunchtime discussion of Rhonda and Paul's sex life has suddenly given Sharon a change of heart about the vacation.

"It was. I just wasn't sure how you felt about it," she says and he knows she's lying.

"I think it's great," he says. "You absolutely love your brother and we both adore Rhonda. Is there a problem?"

"No," Sharon lies again. "We'll have a great time," she says, unenthusiastically. Tim lets it go.

One of the most ironic elements of Tim and Sharon's marriage is that they sleep cuddled up to each other every night except on the nights they make love. Sharon, in her knee length cotton nightgown, spoons against Tim's naked back with her arm around him, or sometimes he spoons against Sharon's back, being careful not to touch her breasts.

A couple of days after their vacation discussion, Sharon climbs into bed and snuggles up against her husband's back as usual. Tim, who had his back to her and didn't see her come to bed, notices the difference immediately. Instead of her normal cotton nightgown, Sharon is wearing something soft and cool; satin maybe? She cuddles up to him and says goodnight. Maybe Rhonda's right. Maybe if Sharon thinks her brother isn't buying into the whole sexual repression, she shouldn't either. He wiggles his ass against her satin covered thighs and says goodnight.

Neither Tim nor Sharon mention the satin nightgown but Tim starts lying on his other side when Sharon comes to bed so he can admire the way it clings to her sexy curves. He cuddles up against her, resting his cock against her satin covered ass.

As exciting a development as this is, Tim is totally preoccupied with fucking Rhonda's ass. He's been doing research on the Internet about anal intercourse so he can make the experience mutually satisfying. He's so excited that he's been jacking off nearly everyday.

The night before he's supposed to meet Rhonda again, Sharon shocks Tim by coming to bed completely naked. Having turned towards the wall when he went to bed, he didn't see her come out of the bathroom so he's completely unprepared when she cuddles up to his back. When he feels the smoothness of her thighs against his ass, he tentatively moves back against her, thinking maybe her nightgown has just ridden up but her bare tits resting against his back assures him she is indeed naked.

She picked a hell of a night to start something, he thinks. All he wants to do is close his eyes and dream about fucking Rhonda tomorrow. The thought of his hard cock pumping in and out of his sister-in-law's tight ass is so erotic that he can't bring himself to deal with his wife's tentative attempts at seduction. He kisses her goodnight and then turns over towards the wall.

Sharon doesn't know what to do. She thought Tim would react more enthusiastically to her new nightgown but he didn't even seem to notice. After a few nights of cuddling him with just the thin satin material between them, she worked up the courage to abandon the nightgown and crawl into bed completely naked. Cuddling against him and pressing her bare tits into his back made her heart pound in her chest and her breathing become labored. She felt an unfamiliar tingling between her legs; reminiscent of the burning itch she had the night she convinced her brother to commit incest.

The sobering thoughts about her brother, combined with her husband's indifference to her exposed flesh, squelches her desires and she dozes off, wondering if she's even capable of becoming a normal wife. While Tim dreams of fucking Rhonda's ass, Sharon dreams about her brother and the only orgasms she's ever had.

Rhonda is pacing the apartment, nervous as a schoolgirl on her first date. Conflicting emotions are raging through her brain; she's scared, nervous, excited and, incredibly aroused by the idea of Tim fucking her ass. She arrived at the apartment early, soaked in the bathtub and has barely eaten all day. She thinks her ass is as clean and ready as it's ever going to be.

Taking a drag on her cigarette, she catches a glimpse of herself reflected in the dark television screen and again wonders if she should put on her nightie. After her bath, she massaged flavored oil all over her body and decided to stay naked while she waited for Tim. Then thinking she looked too anxious, she put her pantsuit back on. A few minutes later, she shed the pantsuit and put on the sheer nightie. Now she's naked again, second-guessing herself, when she hears the doorbell ring.

Tim's cock, already excitedly pushing against the front of his pants, springs to attention when Rhonda opens the door. His eyes devour her naked body and her smooth skin glistening from the body oil.

"You look delicious," he says, closing the door and taking her into his arms. She melts against him, wanting to tear his clothes off as he cups her bare ass cheeks and pushes his tongue into her mouth. Sliding her hand between them, she grips his hard cock through his pants, gently squeezing it in a slow rhythm. Tim moans into her mouth as his hands caress her ass. I'm going to be fucking this ass in a few minutes, he thinks as his cock swells in Rhonda's hand.

"I did some research," Tim says a few minutes later as he starts shedding his clothes. "Two things seem to permeate the information about anal sex. First, you have to be at the peak of arousal; I can take care of that. Secondly, I have to be at the peak of hardness. In other words, I shouldn't have cum yet," he smiles.

"You have it all figured out," Rhonda laughs nervously. "I guess I'll just put myself in your capable hands," she says, wrapping her arms around his neck as he drops his underwear on the floor and stands up. His stiff cock bumps against her leg and she reaches down and gently pulls it up, trapping it between their bodies.

"Capable but inexperienced," he reminds her, "and I can hardly wait to change that." As he moves her towards the bed he adds, "my plan is to eat you through a couple of orgasms," he pushes her onto her back onto the bed, "and then, fuck you until you're almost ready to cum again. Crawling up between her outstretched legs, he continues, "then you should be ready for the main event."

"Mmmmm," Rhonda smiles, "sounds heavenly." Rhonda spreads her legs farther apart and Tim starts licking her inner thighs, getting his first taste of the flavored oil.

"Strawberry?" He gives her a surprised look and Rhonda nods. "My favorite!" he says, teasing her smooth skin with his tongue as he works his way towards her moist pussy lips.

True to his word, Tim's tongue works his magic on Rhonda's pussy. With his fingers pumping her pussy and his mouth sucking her clit, he detonates two explosive orgasms back to back.

"Ohhhhhmyyyyygod!" Rhonda sighs, falling back on the bed, while Tim continues lapping up her steady flow of juices.

"Let's fuck!" Tim says excitedly, moving up next to Rhonda. "Turn over," he tells her, gently nudging her body. "We're going to do my card, so I can lubricate your ass while I'm fucking you." Rhonda had completely forgotten about the doggie style card Tim drew last week.

"You've thought of everything," Rhonda says, still gasping for breath. Rolling on to her stomach, she shakily pushes herself up on all fours. Retrieving the lubricant from the small bag he had dropped by the door when he first came in, Tim positions himself behind her gorgeous ass. His cock throbs with anticipation as he lines it up with her frothing pussy.

"Ohhhhhh! Yeah!" Rhonda moans as Tim plunges his cock deeply inside her well-lubricated hole. Pushing himself tightly against her ass to keep his cock deeply imbedded in her pussy, he squeezes lubricant on his finger and pulls her cheeks apart with his thumbs.

"Oh! Tim! Oh!" Rhonda squeals as he swirls his finger around her puckered opening. Rhonda is rocking back and forth against Tim's hard cock while he corkscrews his finger into her tight ass.

"Oh! Fuck!" Rhonda moans, lunging back at him as Tim inserts a second finger into her ass and wonders how he'll ever get his cock into this narrow opening. Twisting his fingers around, he smears the lubricant and tries to stretch her hole.

"Okay. Time to turn over," Tim says, pulling his rock solid cock from Rhonda's soggy pussy.

"Supposedly the trick is for you to try and relax your sphincter," Tim chuckles nervously as Rhonda rolls onto her back and Tim pushes her legs up to her shoulders.

"Hold your ankles," he instructs as he lines his cockhead up with her crinkled opening. With Rhonda bent in half like this all he sees is ass, pussy and tits. His cock is throbbing at the erotic sight.

"Be careful," Rhonda cautions him. "Take it slowly, okay," she pants, trembling with anticipation and arousal. Taking a deep breath, she consciously tries to relax her ass muscles as Tim pushes forward.

"Okay. Just try to relax," Tim is so excited; pre-cum is dripping from his cock, adding lubricant as he pushes it into his sister-in-law's ass. Fuck! It's so goddamn tight. Rhonda's ass starts stretching around his cockhead and he pushes harder causing Rhonda to lose her grip on her ankles.

"Owwww!" Rhonda yowls. He's going to tear me apart, she panics. "Maybe this wasn't such a good idea," she says, trying to disengage her dilated ass from his cockhead.

"Hold on," Tim pants. "We're almost there," he assures her, pushing down on her ankles and thrusting his thick cock into her compact asshole.

"Owwww! Fuuuuccck!" Rhonda screams as Tim buries his cock into her burning ass. "It hurts!

Take it out!" Rhonda cries.

"Give it a minute," Tim pleads. "It should feel okay in a second." He holds perfectly still as his stiff cock throbs inside her snug little asshole. God! He's never felt anything so constricting around his cock. Rhonda's ass is shrinking around his swollen cock like a fiery vice.

"This will help," Tim says, remembering his research and letting go of one ankle so he can rub her clit. Positioning his thumb over her love button, he rubs light circles as he slowly withdraws his cock. With his cock about halfway out of her ass, he pushes his thumb into her pussy and his palm against her neatly trimmed mound, cradling her clit between his thumb and his palm. Rocking his hand against her clit, he slides his cock all the way back inside her ass.

Rhonda feels completely helpless, bent in half with her brother-in-law's cock ripping her ass apart. What the fuck was she thinking? She can't move! Her ass is burning and she's at his mercy. Oh fuck! Her pussy is on fire now, too! Tim is rubbing her clit and thumb fucking her pussy. She starts rocking against his thumb, but it pushes his cock deeper into her ass. Fuck! It's better if her legs are up higher. She grabs her ankles again and raises her ass up to meet Tim's strokes.

Tim starts a slow, steady rhythm, alternating between his thumb and his cock. When his cock is on the downward stroke, he pulls his thumb out and visa versa. Before long, Rhonda is rocking up to meet his cock strokes, pushing her ass into the air as he thrusts down into her.

"Ohmygod!" Rhonda moans, her orgasm building from the dual attack on her ass and pussy. Her ass has expanded sufficiently to ease the pain and Tim's thumb in her pussy is churning her hot juices.

Tim breathes a sigh of relief as Rhonda gets into it. He didn't want to hurt her, but he sure didn't want to stop! Now they're really fucking and Rhonda is rocking up to welcome his cock into her ass. Fuck!

This is fucking incredible! He can't believe he's actually fucking his sister-in-law's ass!

Rhonda starts jerking as her orgasm hits and her pussy spasms around his thumb. She stops rocking as Tim pulls his thumb from her pussy and slams into her ass a few more times before erupting in a surge of cum that he thinks might never end.

"Fuck!" he breathes, finally pulling his spent cock from Rhonda's ass and letting her legs drop onto the bed. He collapses next to her and just smiles as they catch their breath.

"You okay?" Tim asks sheepishly, breaking the silence.

"Yeah," Rhonda smiles. "It wasn't like I thought it would be," she smiles, "but I came so fucking hard! I can see why women like it but it felt like you were going to tear me apart."

"I'm sorry," Tim says.

"It was my idea but I think I'm going to be sore." Rhonda says, kissing him. "You've nothing to feel sorry about." She grabs a cigarette and abruptly changes the subject. "How are things with Sharon?" she asks.

"Are you allowed to smoke in here?" Tim asks, raising his head and looking around for an ashtray as he avoids answering her.

"No," she says. "But I'm allowed to ass fuck my brother-in-law," she smiles as she points out the absurdity of his question. "Tell me what happened," she says, sitting on the bed and lightly rubbing his back. Tim tells her about Sharon's new nightgown and how last night she came to bed naked for the first time.
