Sister-in-Law Helps Out

"I really am sorry about before," Tim says running his hand lightly across her neatly trimmed bush as he lowers his mouth to her moist lips.

"Ahhhhhhhh!" Rhonda sighs as Tim sucks her labia into his mouth and rubs the tip of his tongue against it. With his hand resting on her pubic triangle, he slides his thumb down to the top of her slit and finds her swollen love button.

"Ohhhhhhyeeaaaahhhh!" Rhonda arches her back and pushes her pussy against him. Tim presses his hand down to hold her still while he gently massages her clit with his thumb and pushes his tongue inside her hungry pussy.

"Oh! Fuck!!" Rhonda is bucking her ass off the bed and squeezing her own nipples as her orgasm builds. Tim slides his mouth up to her clit while slipping two fingers into her drenched pussy, rapidly finger fucking her to an explosive release.

"OooohhhhhhhhhhaaaaaahhhhhhhhhhHHHH!" Rhonda screams as her orgasm rips through her body. She releases her tits as her pussy floods with love juice. Tim pulls out his fingers and hungrily devours her sweet flowing nectar while she pants for breath.

"Oh God!" Rhonda breathes. "I felt that all the way to my toes."

"You mean these toes?" Tim asks as he lightly runs his fingers up the bottom of her left foot and tickles her toes. Rhonda reacts instantly, giggling and squirming away from him.

"You didn't have to break the mood," she says, with a playful pout while pushing against his shoulder with her foot. Tim lightly swats her foot away and drops down next to her.

"We'll get it back," Tim says, gently squeezing her breast and sucking her nipple into his mouth. As he nibbles on Rhonda's fleshy tit, Tim realizes that it's just this kind of playfulness that is missing with Sharon. He hopes they'll get there as their love making progresses.

"Wasn't the first card a sixty-nine?" Rhonda asks.

"Yeah, but I wanted to get you warmed up first," Tim smiles, releasing her tit and pecking her lightly on the lips. "Do you want to be on top?"

"I think that works best," Rhonda agrees. "I don't relish the idea of my head being trapped against the bed if you get carried away," she smiles.

"I didn't think of that," Tim smiles, "maybe I should be on top." Rhonda pushes him onto his back and flips around so she's facing his feet.

"Let me know if I'm smothering you," Rhonda teases as she positions her pussy over Tim's face.

"Or drowning me," he laughs as he pulls Rhonda's dripping pussy down to his mouth. Snaking his tongue into the center of her succulent pussy, Tim feels Rhonda's hand close around his hard cock. "Don't make me cum," Tim warns her. "I need to be at full hardness to slide into your ass."

"Oh, Tim," Rhonda mocks, "you just think of everything." She sucks his cockhead into her mouth as Tim licks and sucks her insatiable pussy. After a few mouth filling sucks, Rhonda relaxes her throat and slides her lips to the base of Tim's hard cock.

"Oh yeah!" Tim moans, his words muffled inside Rhonda's syrupy pussy. Tim isn't even conscious of the competitive spark he ignited when he told Rhonda that Sharon had given him a blowjob. Rhonda's confident that she can out perform whatever her sister-in-law dishes up and she's determined to keep Tim interested regardless of the sex he's getting at home.

Tim is trying to focus on eating Rhonda's pussy but the way she keeps deep throating his cock is distracting the hell out of him. When he feels his cockhead enter her tight throat he can't even think straight.

"Oh God, that's enough," Tim pleads. "If you keep that up, I'm going to cum." He playfully bites her ass cheek and rolls her off of him. "Time for our doggy style anal card," he says. Rhonda excitedly complies, pushing herself up on all fours and wiggling her ass at him. Tim kneels behind her and plunges his throbbing cock into her soggy pussy.

"I assume you want me to use your natural lubricant again, right?" Tim asks as he pumps his hard rod in and out of Rhonda's pussy.

"Mmmmm, feels good," Rhonda breathes just before Tim pulls his cock all the way out and aligns it with her crinkled opening. She takes a deep breath and tries to relax as Tim gently nudges his cock into her ass. Rhonda smiles knowingly, trying to imagine Sharon ever permitting her husband to fuck her in the ass. Lowering her head to the mattress, she reaches between her legs to rub her wet pussy while bracing herself against Tim's intrusively thick cock.

Rhonda's ass is so fucking tight it feels like a second skin stretching around his swollen cock. Tim struggles, inch-by-inch to make his steel rod disappear inside his sister-in-law's ass. When he finally has it buried completely, all the way to his balls, he runs his hands over Rhonda's hips and caresses her firm ass cheeks while gently rocking against her.

"It's better this time," Rhonda murmurs into the sheets while her hand rapidly strokes her pussy. Tim takes this as a cue to gradually start pumping his cock in and out of her snug rear hole. Rhonda presses her middle finger to her clit and applies rhythmic pressure synchronized with Tim's cock sliding in and out of her ass.

Rhonda's pussy is on fire and Tim's hard cock feels wonderful filling up her sensitive ass. Smiling to herself, Rhonda never thought she'd be using this corporate apartment for sex, let along getting ass fucked by her brother-in-law. She's happy that things are improving for Tim and Sharon but she's also glad that she can offer Tim something that he'll never get at home. Even if she is giving him blowjobs she can't imagine her uptight sister-in-law ever letting him fuck her ass.

"Ohhhh yeah!" Rhonda moans as Tim picks up the pace, his balls slapping out the rhythm while his hands tightly grip her hips. All thoughts of Sharon disappear from her brain as her fingers fly over her pussy and Tim pounds her to a magnificent orgasm.

It isn't until later while lathering each other in the shower that Rhonda asks Tim about Sharon. He explains how invigorating their sex life has become; eating her pussy and making love every night but when he gets to the part about Sharon's period and the blowjob, Rhonda cuts him off.

"Whoa, too much information, cowboy," she laughs while lathering his hard cock. "Seriously, I'm very glad it's working out for you two," Rhonda says, looking directly in his eyes.

"I owe it all to you," Tim answers, his hands soaping her luscious tits and tweaking her taut nipples. "I just wish there was something I could do to help you with Paul. We men just don't generally have those kinds of conversations. Maybe I'll think of something before we go to the beach. That's only two weeks away." Rhonda breaks eye contact and looks down at his enticing hard-on before continuing the conversation.

"I guess you won't be needing your Wednesday afternoons anymore," Rhonda says quietly, while cupping his balls and stroking his hard cock.

"Wait a minute!" Tim admonishes her as he tips her chin up face him. "I have no intention of giving this up, Rhonda. What we have... what we have together... I can't imagine ever having with Sharon. You know what it is?" Rhonda shakes her head, anxious to hear what he thinks they have together. Tim searches his mind for the right words to describe sex with his sister-in-law.

"An uninhibited playfulness," he announces, "yeah, that's it. An uninhibited playfulness that is beyond anything I have ever imagined or could ever dream of having with Sharon. Hell, Rhonda, I couldn't stop this if I wanted to."

Their smiles compete for worlds most lustful grin as they attack each other's bodies. Tim squeezes Rhonda's ass cheek with one hand and strokes her pussy with the other. Rhonda jacks him off while teasing his balls and biting his nipples. Eventually she turns around and braces herself against the tile wall and Tim plunges into her smoldering pussy from behind. They engage in the most animalistic fuck they've ever experienced, driving each other to new heights of orgasmic pleasure.

"Do you mind if we don't draw cards for next week?" Rhonda asks while they're getting dressed.

"Whatever you want to do," Tim says, raising an eyebrow as he buttons his shirt.

"I love the cards, but if you don't mind, I'd like a little spontaneity once in a while," Rhonda says, winking as she helps him with his buttons.

"Spontaneity with a little uninhibited playfulness?" Tim asks as he lowers his lips to hers.

"Absolutely," Rhonda answers just before their lips meet.

Sharon is oblivious to the tepid temperature of her bathwater. The empty Popsicle stick is on the floor next to the tub, her eyes are closed and her body is completely relaxed. After settling into her hot bath, she immediately started practicing with the Popsicle, sliding it in and out of her mouth and trying to curb her gag reflex. It was too cold for her to think of it as a real penis, but the size and shape was perfect for what she wanted.

Although she never quite got it down her throat she was bursting with pride when she worked most of it into her mouth without gagging. The Popsicle melted quickly as she worked her tongue all the way around it, slurping her surrogate penis like she'd seen in the videos. With her other hand casually combing her fingers through her pubic hair, she sucked the Popsicle like she thought it would cum.

Without consciously realizing it, her fingers had moved down to the top of her slit, lightly stroking her sensitive clit hood. Having never masturbated before Sharon was shocked at the pleasurable tremor her fingers sent through her body. Still pistoning the Popsicle into her mouth, she spread her legs and rubbed her burgeoning clit more rapidly. Having abandoned her deepseated inhibitions against oral sex she guesses masturbation is a small sin in comparison.

When the Popsicle is completely sucked off the stick, she lets it slip through her fingers over the edge of the tub and uses her free hand to massage her breasts and tease her increasingly responsive nipples.

"Oh God!" Sharon moans, bracing her feet against the tile over the end of the tub as she slides further into the water, vigorously attacking her clit and yanking on her aroused nipples. "Damn!"

she cries as her orgasm builds beyond her wildest expectations. Who knew you could do this to yourself?

"AaaaaaggggghhhhhHHHH!" Her orgasm rips through her body, splashing water out of the tub as she shakes and trembles through her intense release. Gripping the sides of the tub with both hands, she scoots herself up and leans her head against the cool porcelain edge of the tub. Completely relaxed, her mind is consumed with her desire to demonstrate her newly acquired blowjob techniques on Tim.

As she's imagining her lips stretched around her husband's thick shaft, her unbridled thoughts unexpectedly wander to Paul's penis and what it would have felt like in her mouth.

"NO!" Sharon sits up. "What is wrong with me?" she asks the empty bathroom, completely confused about why she can't keep her brother's penis out of her thoughts. Abruptly aware of how cool the water has become, Sharon climbs from the tub and towels off.

Neither Tim nor Sharon mention their desire for an early bedtime but by some unspoken mutual consent they are both in bed before nine. Tim is completely naked and Sharon has on a pair of light blue panties covering her Tampon filled pussy.

"I've been thinking about you all day," Sharon whispers, briefly pecking his lips before kissing a trail from his chin to his chest and sucking his nipples into her mouth. First the left one and then the right one, she nibbles on them until they harden into taut little bumps on his chest. Even after the workout he got from Rhonda, Tim's cock is responding quickly to his wife's machinations.

He smiles excitedly as she continues kissing down his stomach and plants a big kiss on the end of his erect cock. Holding it between her thumb and her index finger so that it is sticking straight up, her tongue bypasses it completely and starts licking his balls. Lightly stroking his hard cock with her thumb and finger, she licks under and around his balls, gently sucking each one into her mouth.

"Oh yeah!" Tim moans when Sharon finally takes one long lick, gliding her tongue from his balls to the tip of his hard cock. Slipping just the tip in her mouth, she runs her tongue over the end of it like she did with the Popsicle.

"Do you like that?" she asks nervously, lifting her lips from his cock. "Would you like some more?" Sharon is trying to mimic the playful teasing that was evident in every video she explored.

"God yes! Sharon, this is... you are...!" he pants as she keeps licking long strokes up the under side of his cock and nibbling on the swollen head. Stroking her hand up and down the length of his rod, she begins caressing his balls as she closes her mouth over the end of his saliva-coated cock and gently sucks on his cockhead.

As Tim is wondering how his wife transformed into a blowjob fantasy come true, her tongue flicks the underside of his cock sending intense pleasure signals that all but eliminate any rational thought. Sharon is pleased with her success but nervous about the taste. This is the part she didn't practice... what if she gags again?

"Ohhhhh! Yeah! Mmmmmm!" Tim moans as she continues stroking and sucking his cock and playing with his balls. Sharon creates a steady rhythm with her mouth while her tongue is in constant motion along the underside of his cock. By the time she starts rolling his balls back and forth with her hand, Tim is jerking his ass off the bed trying to drive his cock deeper into her warm mouth. Okay... I can do this, Sharon mentally urges herself on as she speeds up the stroking of her husband's throbbing cock.

Thankfully, Sharon recognizes the signs and knows Tim is getting close. She squeezes her eyes shut and valiantly stays right with him, stroking and sucking and playing with his balls. She imagines the popsicle about to melt and begins a rhythm of swallowing, sucking, swallowing just seconds before Tim erupts inside her mouth. OhmyGod! There is so much of it. It's going down my throat. I'm swallowing it!

"AaaahhhhhhhhHHHH!" Tim groans as his cum spews forth in staccato like bursts filling his wife's mouth as she struggles to swallow fast enough. Sharon keeps stroking, sucking and swallowing but some of it still runs out of her mouth and down his hard cock.

When he's fully spent, Tim falls back on the bed, panting. Un-fucking-believable! He wasn't sure what Sharon would do when he came, if she'd run from the room like she did last night. But there she is, still swallowing, taking every drop. When he stops spasming, she lets his cock slowly plop from her mouth and onto his stomach.

Sucking in a huge breath and smiling from ear to ear, Sharon glides her tongue down Tim's sensitive shaft, cleaning up the cum that overflowed out of her mouth. My god! I can't believe I just did that. It's just like the videos... except it was better than the videos!

"I'm learning," Sharon whispers demurely, releasing his spent cock and snuggling against her husband's warm body.

"You are unbelieveable!" Tim whispers, kissing the top of her head. I can do better, Sharon thinks as she drifts off to sleep.

A blowjob becomes their new nightly ritual. As soon as she comes to bed, Sharon aggressively attacks Tim's cock, and true to her prediction, she improves her skill with each undertaking. Tim finds himself lasting longer and cumming harder with each night's blowjob. Sharon continues to seek instruction from the Internet, trying new techniques to pleasure her husband's cock.

Once her period subsides, Sharon doesn't abandon the nightly blowjob. She just continues sucking Tim after he cums until he's hard enough for her to mount him with her feverish pussy. She loves being on top and riding his cock to a screaming orgasm, enhanced by the lingering taste of his cum on her tongue.

Sharon's dreams have become lust-filled cocksucking fantasies. Mostly Tim's cock but sometimes she dreams of sucking Paul's cock and a few times she's even dreamt of them together. She wakes up in a sweat with her pussy soaking wet after dreaming about her husband and her brother naked in her bed while she strokes their hard cocks and alternates feeding each one into her warm mouth.

She can't understand why her brother keeps intruding into her sexual fantasies or why she finds it so arousing when he does. As their beach trip gets closer, his presence in her fantasies increases significantly and she even wonders if there will be an opportunity for her and Paul to be alone. As soon as this thought enters her brain, Sharon banishes it. What am I thinking?

A few days before the beach house vacation, Sharon and Rhonda go shopping for new swimsuits. Sharon has always worn a conservative one-piece swimsuit but Rhonda convinces her to try something a little sexier. In the dressing room together, Rhonda raves about a pale yellow bikini that barely covers Sharon's perfect breasts and exposes a fair part of her ass cheeks.

"I could never wear this," Sharon laughs, turning to look at her exposed flesh in the mirror.

"Why not?" Rhonda asks. "You've got the body for it. Take advantage of it while you can."

"Would you wear this?" Sharon asks, cupping her breasts to emphasize how exposed they are.

"I will if you will," Rhonda answers, wondering what Tim will think when his wife and his lover show up in matching Brazilian-cut bikinis. The idea is too good to pass up and Rhonda leaves the dressing room to find the exact bikini for herself.

"Well..." Sharon keeps turning to look at the bikini from different angles, imagining what Paul might think when he sees so much flesh. Damn! Why did she think of her brother instead of her husband? And why does that make her pussy tingle?

When Rhonda returns, Sharon averts her eyes as her sister-in-law slips into an identical bikini. Catching a glimpse of Rhonda's naked body in the mirror, Sharon stares at her ample breasts and neatly trimmed pubic area. When they stand next to each other in front of the mirror they could easily be mistaken for twins. Rhonda's breasts are larger and her hips are more pronounced but with the amount of bare flesh showing the differences are miniscule.

"Let's not say anything to Tim or Paul and surprise them at the beach," Rhonda whispers while they wait in the checkout line.

"That's a great idea. I can't wait to see their reaction," Sharon answers and the two women almost start giggling, each one oblivious to the other's thoughts. Rhonda is anxious to see how Tim reacts to the two women he's having sex with dressing identically while Sharon is wondering what Paul will think of her new swimsuit.

On the drive to the beach house, Tim and Sharon are both quieter than normal, lost in their own thoughts. Sharon is worried that spending a week at the beach with her brother will fuel more lustful thoughts and dreams, and at the same time, anxious to see his reaction to her revealing bikini. These conflicting emotions keep her occupied most of the drive, just gazing out the window.

Tim, on the other hand, is busy formulating a plan to help Rhonda improve her sex life with Paul. He figures that since Sharon became more amorous after Rhonda lied to her about Paul's sexual prowess, maybe the reverse will be true. If Paul thinks he and Sharon have an adventurous sex life it might help him shake off his parent's teachings.

If he remembers the beach house layout correctly, from viewing it on the website, the two master bedrooms are upstairs and next to each other. Although not a screamer, Sharon can be quite loud when she's in the throes of an intense orgasm. Tim's plan is to induce such powerful orgasms in his wife that there will be no doubt that she's no longer the prude their parents wanted.
