Sister-in-Law Helps Out

Over the next three days both couples act like sex-crazed teenagers, prone to sucking and fucking all night, changing partners each day, groping each other on the beach and taking long midday naps. Paul's enthusiasm builds and he starts fucking his wife with nearly the same intensity as he fucks his sister. Both women are eagerly sucking the mens' cocks but only Tim is eating their pussies. Neither woman has broached the subject with him. His first night with Rhonda, Tim eats her to two explosive orgasms, and then at her suggestion, fucks her in the ass. By Saturday morning whatever inhibitions any of them brought to the beach house are gone.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

"Get your asses down here!" Rhonda says.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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