Sister-in-Law Helps Out

Rhonda and Paul are already at the beach house when Tim and Sharon arrive. Tim excitedly verifies that the bedrooms are just as he expected, only better. The headboards of the king size beds butt up against the common wall. As they unpack, he wonders if he should let Rhonda in on his plan.

It's early evening by the time each couple is settled in and the four of them venture out for dinner. There is a locally famous eatery just down the beach within walking distance. They cut across the sand and up the boardwalk. Over dinner they discuss plans for the week.

"Let's hit the beach first thing in the morning," Rhonda says, while they're enjoying their salads.

"Sounds good to me," Sharon answers, smiling at Rhonda. Both women are anxious to show off their new swimwear.

Over their entrees, they discuss various other activities for the week, with Tim mentioning a used bookstore he'd like to visit. Paul says he'll go along with what everyone else wants to do. Tim is still looking for an opportunity talk to Rhonda when the check arrives. Oh well, she'll know soon enough.

After a nightcap on the balcony where they commit to an early morning on the beach, the couples retreat to their respective bedrooms.

Tim pulls back the covers invitingly. Already excited by the exhibitionist nature of what he has planned, Tim's cock stiffens even more at the sight of his shapely wife emerging from the bathroom. Her naked flesh, basked in moonlight from the open window, gives off a seductive glow as she makes her way across the room. No longer shy about her body, Sharon absorbs her husband's stare and she smiles while relishing the pleasure he gets from looking at her well-toned body.

"You are stunning," Tim says as Sharon crawls in next to him. "And you look delicious," he adds as his hand caresses her hip and his lips brush against her right nipple.

"Tim!" Sharon laughs, "Rhonda and Paul might hear us."

"We'll be quiet," Tim answers, knowing that he has just the opposite planned. His hand moves across her hip and between her legs while his teeth nibble on her quickly responding nipple.

"Mmmm," Sharon rolls onto her back and spreads her legs. "If you're sure," she sighs.

Tim lightly strokes her outer labia, which is already covered with a thin coating of natural lubricant. He marvels at how responsive his wife's body has become when just a few weeks ago he thought it would never thaw. Slipping one finger inside her, Tim moves his mouth to her other nipple, teasing it to it's full thickness.

"Ahhhhhh," Sharon moans, holding him tightly to her breast as his finger starts a steady rhythm inside her aroused pussy. Tim kisses his way down her stomach, replacing his finger with his tongue. Licking all around her puffy lips, he laps up the juice that's boiling over inside her inflamed pussy.

Sharon lifts her legs, spreading them wide apart and Tim slips her arms under her knees before running the tip of his tongue up and down the length of her slit.

"Oh! Yeah!" Sharon nearly bellows when he pushes his tongue all the way inside her and licks around the insides of her wet pussy. "Oh! God!" Sharon squirms on the bed, pushing her smoldering pussy against his tongue. He rapidly pistons it in and out, tongue-fucking her as she grabs his head and humps her pussy against his face.

Sharon's juices are flowing and Tim's face is soaked when he shifts his focus from her sweltering opening to her clit. Licking from inside her drenched pussy up to her exposed clit, he covers it with saliva and pussy juice before sucking it into his mouth. Gently sucking with his lips, he flicks his tongue against her clit several times eliciting loud moans from Sharon.

"Oh! Tim! Ohhhhhhhh! Yeah!" Sharon's moaning is getting louder as she entwines her fingers in his hair and yanks his head against her gyrating pussy. Somewhere in the back of her mind, Sharon realizes that she can probably be heard in the next room but her rapidly building orgasm shuts down any restraint she might have.

"Oh! That's it! Keep... doing... that!" She gasps out the last words while thrusting her hips off the bed, slamming her clit against his tongue. Tim keeps feverishly sucking her clit while pushing two fingers into her soggy pussy.

"Oh God! That's so good! Ohhhh! So good! OHHHHH YEAH" Sharon yells, squeezing her legs together while pushing Tim's face from her sensitive clit. As she falls back on the bed, panting, Tim shakes his head loose from her fingers and begins lapping up the thick cream oozing from her quivering pussy. And that's just round one, Tim thinks.

In the next room, Rhonda is smiling to herself as Paul tosses and turns next to her, putting the pillow over his head. At first she wasn't sure what she was hearing because the wall muffled the sound. But when the headboard started tapping the wall behind them and she heard her sister-in-law moaning, it confirmed her suspicions. She wonders if Tim is doing this on purpose to get a reaction from Paul or if this is just their normal nightly routine. By the time Sharon yells her last oh yeah, Paul has jumped out of bed and walked out on the balcony in his pajamas.

"Are you okay?" Rhonda asks, wrapping her arms around him from behind, her thin nightgown offering little protection from the cool night air.

"Who can sleep with that... that... noise? You'd think they'd have a little consideration!" Tim growls. Rhonda can't remember seeing him this angry in a long time. Does he feel his sister is betraying a sacred family oath or is it something else? She tries to sooth him.

"I think they're done, if you want to come back to bed." She smiles as she rubs her body against his back, hoping the moaning might have stirred a positive reaction in her husband.

"Don't you start!" Paul snaps, moving away from her. "Isn't one inconsiderate couple in this beach house enough?" He stomps back into the bedroom and throws himself on the bed with a huge sigh.

Rhonda stays on the balcony, hugging herself and wishing she was in the next bedroom with Tim. Hell, she'd even share him with his wife if he'd make her moan like that. She shrugs and starts back into the bedroom when she hears the telltale squeak of the bed in the next room. Ohmygod, they're not done. She smiles and turns back to the balcony.

Tim never stopped lapping up his wife's succulent cream. He gently licked all around her sensitive pussy, occasionally flicking his tongue between her splayed open lips. By the time she caught her breath and was no longer panting, her arousal was on the rise and her pussy was anxious for more.

"God, Tim! What you do to me!" she cries, spreading her thighs wider and pulling on his hair again. Tim loves the taste of his wife's pussy. He could eat her all day and never get enough. Moving his mouth up to her clit again, he sucks it into his mouth while once again pushing two fingers into her wide-open pussy.

"Oh Tim! That's soo.... SOOO... GOOD!" Sharon cries as he sucks on her clit and pumps his fingers in and out. Sharon is jerking wildly and he's having trouble keeping her clit in his mouth.

"OHMYGOD! OHMYGOD! OHMYGOD!" Sharon is screaming and her whole body is spasming as she gushes a steady stream of creamy nectar over Tim's fingers and down his chin. Tim releases her clit to lap up her thick, syrupy juice. Her body is quaking and her pussy lips are quivering as he licks her inside and out.

Even before she catches her breath, Tim slides his body over hers and plunges his rock solid cock deep into her in one hard thrust. Her still quivering pussy engulfs his cock like a velvety glove and Sharon's hips instantly start keeping rhythm with his steady pounding.

"Oh! Oh! OHHHH! OHHHH!" Sharon's moans mirror Tim's jackhammering thrusts. Her thick, hot juices make his cock feel like it's gliding through hot gelatin as he pummels her inflamed pussy.

"Oh Tim! It's building again! Oh Tim! TIM! TIM!" Sharon is digging her fingernails into his ass cheeks spurring him on. Tim knows what really gets his wife's blood boiling and he slips his arms under her, holding her against him as he rolls them over, placing her on top.

Sharon pushes herself up into a sitting position and starts riding his hard cock like a wild woman. Tim just smiles as she jounces on his cock and the headboard starts banging against the wall.

She's slamming her pussy down so hard he's afraid she'll pulverize his hard-on with the force of her attack. He grabs her taut nipples, twisting them and stretching them out from her bouncing tits. His cock is throbbing from her ferocious onslaught and he tenses his legs as his balls constrict, ready for the eruption that is seconds away.

"Ahh! Ahh! AHH! AHHHHHHHH!" Sharon's moans are synchronized with her bouncing and Tim can actually feel the pressure of her juices against his cock as waves pleasure flow through her body. Her pussy grips his cock and she slams down hard against him as he shoots his load deep inside her quivering pussy. Her whole body is trembling as she collapses on his chest, her soft tits cushioning her fall, while her pussy pulsates like a vibrator, milking the last bit of cum from his cock.

They're both breathing hard, but Sharon is gasping for breath. Her head is on Tim's shoulder and her blonde hair is wet and matted from her intense exertion. He strokes her hair and kisses her gently on her sweat-soaked forehead while wondering what Rhonda thought of their exhibition.

Rhonda can't figure out why her husband is so mad about the noises coming from the next room. She thinks it's kind of arousing and wishes Paul would do something about it.

Paul can't figure it out either. Why should his sister breaking their vow making him so mad? As he lies on the bed listening to her moan he can vividly picture exactly what she's doing. He can visualize her naked body and her gorgeous bouncing breasts. He still dreams of how she straddled him and nearly drove him insane.

"Maybe we should make a little noise of our own," Rhonda says, noticing the tent in the sheet as she crawls in beside him.

"I don't think it's a contest!" Paul snaps and then is instantly ashamed that he's taking this out on Rhonda. It isn't her fault. She's the best wife anyone could ask for.

"I'm sorry," he says, turning towards her and noticing she's shed her nightgown.

"Show me you're sorry," Rhonda smiles, pressing her naked thigh against her husband's pajamacovered hard-on. Paul surprises Rhonda by rolling her onto her back and pulling off his pajamas.

As Paul positions himself over his Rhonda's body and aligns his cock with her moist pussy, he's hoping that making love to his wife will take his mind off of his sister. He doesn't know why he keeps dreaming about that night with Sharon and he's still angry with her about breaking her vows but he gently slides his steel-like rod inside his wife's anxious pussy.

Responding to the noises from the next room, Rhonda is wet and ready. Closing her eyes, she can imagine from Sharon's moaning exactly what Tim is doing to her. She knows from experience how Tim uses his tongue and then slams in with his hearty cock. As Paul continues his mechanically rhythmic fucking, Rhonda bucks her hips, trying to push him to a more adventurous level of lust.

When Paul momentarily speeds up just before he cums, Rhonda is close to her own orgasm. Close... but not close enough. She drops her head on her pillow with a sigh, wondering how she's going to get Tim alone to satisfy her needs.

"Good morning," Rhonda says, joining Tim and Sharon on the terrace.

"I found a donut place," Tim says, biting into a chocolate raised donut and pointing to the box.

"And there's coffee," Sharon adds, smiling meekly at her sister-in-law, obviously embarrassed by what Rhonda and Paul must have heard the previous night.

"It's easy to work up an appetite at the beach," Rhonda smiles, grabbing a cream-filled Žclair and biting one end off. As Tim takes a drink of his coffee, Rhonda sucks the cream from the end of the Žclair and raises her eyebrow at him. Sharon is behind Rhonda and doesn't see the suggestive maneuver but Tim nearly chokes on his coffee before he smiles at his sister-in-law.

"Hey, sleepy head," Rhonda says when Paul steps out on the terrace dressed in his swimsuit and a Hawaiian print shirt. Paul nods as he pours some coffee.

"I thought we were going to the beach this morning," he says although there is little enthusiasm in his statement.

"We are!" Rhonda jumps up and nudges Sharon to follow her. "Wait here while we get ready."

"Be right back," Sharon gives Tim a kiss on the cheek and follows her sister-in-law into the house. After Tim makes a couple of attempts at small talk without much response from Paul, the two men fall into an awkward silence, watching the waves crash against the sand.

"Are you sure about this?" Sharon whispers even though there is no way she can be heard from the terrace. "The amount of cleavage is bad enough, but the bottom only covers half of my ass cheeks."

"That's the point!" Rhonda says, tying the string behind her back and adjusting the triangles across her ample breasts. "Come on, you'll see." Rhonda says, grabbing Sharon's hand and leading her out of the bedroom.

"Okay, boys!" Sharon calls just before they reach the door to the terrace. "We're ready!" Tim and Paul stare dumbfounded at the exotic site of the two women entering the terrace.

"Ohmygod!" Tim nearly chokes on his coffee again as his eyes feast on the two scantily clad women.

"Where did you get those swimsuits?"

"Why did you get them is more the question," Paul asks, incredulous that his wife and his sister would be willing to display so much flesh. "Sharon, my god! You can't wear that!"

"Oh, but your wife can?" Rhonda asks, strutting over to where her husband is standing. While Paul's eyes shift to his wife's bouncing breasts, Tim follows the rippling flesh of her half exposed ass cheeks.

"No! I didn't mean that!" Paul tries to recover from his focus on his sister. "Neither one of you can! Don't you agree, Tim?" Paul asks, looking to his brother-in-law for support.

"I think they look sexy as hell and we'll be the envy of every guy on the beach," Tim answers, smiling from ear to ear as he shifts his gaze from his wife to his lover, mistakenly believing that he's the only one who's fucked both of these gorgeous women.

"Then let's go before we change our mind," Sharon says, grabbing her beach bag with one hand and her husband's arm with the other she pulls him down the steps to the beach. Rhonda tries to grab Paul's arm but he pulls away, scowling.

"Fine. Be Mr. Grumpy," she smiles, running to catch up with Tim and taking his other arm. Several male heads lift from their towels as they watch Rhonda run across the sand, her barely covered breasts bouncing against her chest and her ass cheeks dimpling in and out with each stride. Paul shakes his head and runs to catch up with the group.

"I think you're going to need some sun screen so you don't burn," Tim tells his wife as he pulls the tube from the beach bag. They've settled on a blanket in a secluded little alcove near the water line and both women are lying on their stomachs. Tim admires the view of their nearly identical asses only half covered by their bikini bottoms. While certainly not thongs, their swimsuit bottoms are cut high enough to leave a lot of flesh exposed.

"Maybe you should do me and let Paul put sunscreen on Sharon," Rhonda says. "I don't want to lose you two for the afternoon if you get carried away," she smiles.

"Rhonda!" Sharon admonishes but her heart is beating rapidly at the thought of her brother touching her naked skin. She squeezes her thighs together and tries not to show her excitement.

"Fine. Whatever," Tim tries to act nonchalant but is very willing to rub sunscreen all over Rhonda's bare ass cheeks.

"That's okay," Paul says. "I can do Rhonda and you can do Sharon." Sharon turns her head to hide her disappointment.

"No, do your sister, silly." Rhonda says playfully while scooting over next to Tim. "Come on, Tim. I don't want to burn." Paul shrugs and acquiesces to his wife's choice. Not wanting to make a scene, he slowly turns his attention to his sister.

Rubbing sunscreen on his hands, Paul begins rubbing the back of Sharon's legs, methodically covering her with the creamy lotion. Sharon spreads her legs as he works his way up her shapely thighs. Paul is trying to think about anything besides his sister's nearly naked body as he spreads the sunscreen evenly across her thighs. His heart is pounding and he's sweating while his brain is filled with the vision of Sharon astride his hard cock when they were in college.

Tim, on the other hand, has turned Rhonda's sunscreen application into an erotic massage. Taking advantage of Paul's back to him and Sharon's head turned the other way, he caresses up her inner thigh and brushes his fingers across her bikini covered pussy lips. Rhonda stifles a moan as Tim gets bolder and, without taking his eyes off of Paul or Sharon, slips one finger inside Rhonda's swimsuit bottom, feeling the moist heat emanating from her aroused pussy.

Rhonda puts a fist to her mouth as her brother-in-law's finger glides between her slick pussy lips. With his other hand applying sunscreen to her exposed ass cheek, he makes it look like he's rubbing sunscreen with both hands.

"Don't forget those dimpled cheeks, Paul," Tim says as he watches his brother-in-law skip over Sharon's bottom. "We don't want them burned."

"Yes, please, Paul," Sharon murmurs. "Make sure I don't burn." Sharon's pussy is on fire as her brother's soft, gentle hands caress her warm skin. She holds her breath, waiting anxiously for him to get to her ass cheeks. She's unconsciously clenching her pussy muscles in an attempt to appease the arousal building between her legs. Paul's cock is responding to his sister's bare flesh and he shifts sideways to conceal his growing erection.

All pretense of applying lotion is gone and Tim is outright finger-fucking Rhonda while her husband and his wife are only a few feet away. Rhonda is biting down on her fist as she rocks against his hand and her orgasm builds inside of her. Turning her head towards the others to watch for signs of discovery, she lifts her ass up giving Tim greater access. Tim withdraws his finger from her pussy, replacing it with his thumb while his middle finger teases circles around her aroused clit.

Tim's machinations coupled with the risk of discovery drives Rhonda over the top. She clamps her hand over her mouth as a tremor flows through her body, coating Tim's hand in hot pussy juice. While catching her breath, Rhonda notices her husband is still caressing his sister's ass cheeks. His touch is light and gentle, but Sharon has her legs spread and seems to be rocking with his slow caress.

But the real shocker is that her husband's swimsuit trunks appear tented in the front. My God!

He's got a hard-on over his sister's ass. Well, Rhonda muses, what man wouldn't react to touching an ass like that, sister or not. But, still it's his sister! She closes her eyes and her lips form a knowing smile as she basks in the afterglow of her much need orgasm. Sharon turns her head towards them as Tim applies sunscreen to Rhonda's back.

Sharon's pussy is on fire from her brother's lingering caress of her warm ass cheeks. She turns her head to check whether Tim or Rhonda have noticed how long he's taking with that part of his sunscreen application but neither are paying any attention. Rhonda has her eyes closed, almost like she's sleeping and Tim is concentrating on rubbing sunscreen on her back. Sharon sighs and closes her eyes, undulating her hips to her brother's massage.

Paul knows this isn't right but he can't seem to move his hands form his sister's nearly bare bottom. His vivid memory of her naked body writhing on top of him is fogging his brain and making him uncomfortable. He knows he should stop but his hands aren't listening to his brain. He glances behind him to see if he's being watched while wondering why Sharon hasn't said anything. She seems to be rocking her hips in encouragement. God! This is wrong!
