While Steve and Louise were fucking upstairs, Sally and Marie were swimming outside in the Olympic-sized swimming pool.
"Oh, I hate this long hair! After a swim, it gets all tangled and it drives me crazy!" Sally pouted, climbing out of the pool sometime later.
"I love your hair, Sis! It's beautiful," Marie murmured.
Sally emerged dripping from the pool with her sister right behind her. The two grils entered a rear wing of the house, an inner room with showers and changing rooms. Both of the young teenagers were wearing very brief bikinis which highlighted their stunning, curved bodies.
Sally's hair, dark with dampness, was long, thick and glossy and it spilled down her shoulders, falling to the middle of her back.
"Shit! I'll never get this hair all untangled!" she complained.
"I'll do it for you," Marie said, eyeing her sister hungrily.
"Thanks, Marie, that's sweet," Sally said with a grateful smile at her sister.
Sally turned and studied her reflection in one of the many mirrors that lined the wall of the dressing room. In the glass, she watched Marie coming up behind her. Sally swallowed hard, realizing that her sister always seemed to exude an aura of sexuality.
Marie stood so close to her now that her warm, moist breath played on the nape of Sally's neck, naked now as Sally gathered up her hair in her hand.
Sally shivered in anticipation of what was about to happen between her sister and herself.
"Are you cold?" Marie murmured.
"No! Just the opposite! You're making me really hot!" Sally responded.
Marie laughed delightedly.
Her sister's lewd-sounding laugh made goosebumps rise on Sally's flesh and her tingling nipples stiffened. Marie kissed the back of Sally's neck. Then she reached around to the girl's front and put her hands on the bikinied tits. One hand per tit.
As Sally moaned in response, Marie stroked the girl's tit-flesh where it rose from the cups of the bikini. The girl's nipples stiffened and jutted out like rocks.
"Unmmm, good," Sally moaned as her sister fondled her tits.
"Come with me, honey," Marie murmured.
"Yes."
"I'll take care of you. I know what you need," Marie said excitedly.
"Mmmm, good. Where are we going?" Sally asked dreamily as her sister took her by the hand.
But Marie just giggled and led the other girl down the line of dressing rooms to the one at the far end of the room. The dressing rooms were actually very luxurious and oversized with more than enough room in them for two.
The large dressing room had a mirror on the wall and protruding from one of the walls were hooks for clothes. The two bikinied teenagers entered the room and Marie closed the door and bolted it shut.
She turned to face Sally, whose arms were already extended for an incestuous embrace that would not be entirely sisterly. Marie stepped into her sister's arms and the two girls rubbed their wet sleek bodies together.
Their mouths met.
"Mmmmm," bath of the aroused teenagers moaned as their tongues locked together.
Sally's full firm tits nuzzled Marie's large bust, tit pressing lewdly against tit. As they rubbed the large tits together, their tongues continued to rub against each other and they swallowed each other's saliva.
Marie's hands busied themselves behind Sally's back, unhooking the catch of the bikini top, opening it. The back strap was open now, but the bikini remained on Sally, covering her, held in place by Marie's tits pressing against Sally's.
Marie's stiffening nipples strained against the tight bikini top as Sally reached behind her, unhooking the catch of that bikini top.
Marie's red-nailed hands slid down Sally's hand, tracing the girl's curves, dropping to her well-rounded ass.
Marie fondled the other girl's asscheeks where they rose from the bikini. Sally leaned into Marie, pressing against her crotch. Marie slipped one hand inside the other girl's damp bikini bottom.
"Ohhhhh!" Sally gasped as she felt her sister's hand caressing, kneading and squeezing her asscheeks.
The teenagers broke off their kiss, coming up for air.
"God, you're turning me on so much, Sis!" Sally said, giggling, her tits bobbing. Her bikini straps slipped from her shoulders to the middle of her arms.
Marie grinned at the other girl as she reached out, took hold of the front of Sally's bikini top and took it off her. A pair of creamy white tits popped into view.
"Oh, baby, your tits are gorgeous!" Marie groaned, letting the bikini top fall to the floor and cupping Sally's tits, one in each hand.
Her firm globes of tit-flesh trembled in Marie's hands which gently kneaded and fondled them. The nipples were long and rapidly stiffening.
"Ohhhh, yesss," Sally hissed.
Marie released her sister's tits, and they were so firm they stayed in place. She pulled down the girl's wet bikini bottoms, tugging them off Sally's wriggling hips. Sally stepped out of her bikini. She was completely naked now.
Her golden cunt bush was thick and full and dark with dampness from the pool water, like the hair on her head.
"It's not fair, Marie! I'm all naked, but you still have your bikini on!" Sally cried.
She spread her feet, tilting her hips to one side, striking a deliberately sexy pose. She slipped one hand between her own legs and fondled her cunt.
Marie kept her eyes on her sister's crotch while she slipped her own bikini off. In seconds, she was as naked as Sally.
"Mmmmmm, you're gorgeous!" Sally said, laughing excitedly.
"Sos are you, honey!"
Marie's nipples were large, fat, stiff, set in wide rosy circles with blurred edges. Her pussy was moist with pool water and her own fuck juices, and its hair was blonde just like the head and pussy hair of all the Mathews girls and their mother.
Sally's mouth watered as she looked her sister up and dawn. Her fingers rubbed her own cunt, moving up and down, her pussylips darkening with hot blood as she turned on more and more.
As Sally continued to stroke her little wet pussy with one hand, she moved her free hand to her chest and toyed with her stiff nips, pulling, rolling, tweaking them.
As she stroked herself, Sally let her fingers part her pussylips, showing the bright pink wet cuntmeat to her sister's hungry gaze.
Marie moved closer to Sally and, looking into her eyes, she took hold of the girl's hand, the hand that had been handling her pussy. And Marie guided that hand to her mouth.
Never taking her intense gaze from Sally's eyes, Marie stuck her tongue out and slowly licked Sally's pussyjuice off her trembling fingers.
"Why settle for that when you can have the real thing?" Sally asked meaningfully.
The teenagers rubbed the naked bodies together, grinding their crotches together lewdly as they kissed over and over again, their tongues flicking at each other.
Their naked tits pressed together, Sally's longer nips fencing obscenely with Marie's stiff nubs of tit-flesh. Their cunthairs intertwined as they ground their cunts together, crotch against crotch.
Marie's pussylips burned as they were rubbed by Sally's, and both girls moaned with excitement into each other's mouth. Sally reached around and fondled her sister's ass which swelled outward, a pair of fleshy melons divided by a deeply plunging cleft. Sally gripped the other girl's ass, one cheek in each hand. She spread her fingers outward, resting them on the quivering ass-flesh.
As Sally stroked and squeezed Marie's ass, the two girls continued to hump their crotches hard against each other, their stiff tits growing stiffer and longer, reaching out toward each other.
Sally pulled her sister's asscheeks apart, then mashed them together. A few minutes later, the incestuous lovers broke their forbidden embrace, but only so they could hurry over to the padded bench at the rear of the large dressing room.
There, Marie eased Sally down on her back on the bench. Then she mounted her sister and stretched out on top of Sally, who moaned hungrily. Her moans increased when Marie, crouching over her, let her heavy tits dangle directly on her face.
Marie swayed her upper body from side to side, making her big tits rub and softly slap against Sally's face. Sally planted hot quick kisses on her sister's tits.
Marie's fat nipples throbbed as they glided over Sally's mouth.
"No fair teasing!" Sally said with a mock pout.
"Why, whatever do you want, darling?" Marie asked, giggling, knowing very well what her sister wanted.
"More of your tits for starters!" Sally said. Marie giggled again as she stuffed one of her stiff nipples into Sally's mouth. Sally gripped her sister's nipple between her tightening lips and she began to suck hard.
After a few minutes, Marie slipped her nipple free of the other girl's mouth.
"Hey!" Sally protested. "I was just getting started!"
"Here, have another one," Marie said with a grin as she cupped her other tit and offered that nipple to her sister's mouth, rubbing her nip against the girl's moist, puckering lips.
Sally stroked her sister's nipple with the flat underside of her tongue before sucking it into her mouth. She sucked hard, tonguing with the tip of her tongue while she hollowed her cheeks inward to increase the suction on Marie's nipple.
"Ohhhh, yeah, that feels great, Sis!" Marie cried, rocking back and forth on top of Sally's body.
"Enough of that for now, babycakes," Marie said a few minutes later, tugging her nipple free of her sister's mouth.
Sally's lovely young face was bright with rosy spots of color on her cheeks. And fires of fucklust smoldered in her eyes.
Marie's nipples shone with saliva as she rose to her hands and knees. Moving carefully, the young girl reversed her position. She now straddled Sally's head and faced the girl's feet and her quivering little pussy.
Sally's upturned face was framed by Marie's creamy thighs. Sally stared upwards, noticing how her sister's tangled pussy curls covered the swelling bump of her mound.
"Oh, God, yes," Sally moaned, opening her mouth as the other girl's cunt hovered over her face. She desperately lifted the back of her head from the cushion but she still could not quite reach the tempting-looking pussy above her.
Marie enjoyed teasing her sister. She deliberately wiggled her hips, waving her crotch back and forth, just out of reach of her sister's mouth.
"Marie, please! You know how I hate it when you do that! Please let me lick your cunt!" Sally pleaded.
"Okay, baby, take it easy," Marie purred as she lowered her hips, pressing her crotch against the girl's face.
Sally rested her head back down on the cushion and Marie's pussy followed her down, covering the lower half of her face. Marie's pussy showed fat, fleshy lips, a tempting mouthful of cuntflesh.
The pussylips lewdly parted as they pressed against the lips of Sally's gaping mouth. Marie's pussylips split and spread wider, sliding sideways and exposing pink meat which dripped with fuck juice.
The heady aroma of teenaged pussy in heat struck Sally's nostrils and she flared them, not wanting to miss out on one single whiff of the arousing musk.
Sally inhaled deeply, breathing in the aroma and furnace-like heat of her sister's cunt. She moaned with excitement and kissed Marie's pussy, moving her lips all over the wet cunt against her mouth.
"Oh, yeah, baby, you've got it," Marie groaned, squatting over her sister's face, savoring the incredible sensation of her horny little cunt being kissed by the other girl.
She wiggled her hips, rubbing her crotch obscenely against her sister's face. More and more cuntjuice poured out of Marie's pussy and flowed over Sally's face.
Marie leaned forward, making her pussy press even more tightly against her sister's open, kissing mouth.
"Unnnhhhh, ohhhh!" Marie cried as she felt her sister's long painted tongue thrusting inside her.
Sally snaked her tongue inside Marie's cunt, rolling against the heaving cuntwalls, lapping up all the flowing fuck juices.
"Oh, yeah, baby, yeah! Fuck my cunt with that great long tongue of yours!" Marie groaned.
Marie leaned forward even more and pressed her tits against her sister's body. Her red nailed fingers rested on Sally's smooth inner thighs. She spread them a bit wider and pressed her head between them.
Heat rose in Sally's cunt as she felt Marie plastering lewd kisses on her pussy. Her ass, dripping with sweat, clenched tightly as she rocked her hips, desperate to feel Marie tongue fucking her pussy.
Marie kissed her way up and down the other girl's pussy, feeling the juice-soaked pussy curls smearing across her face.
Marie's fat pink tongue unrolled from between her ripe red lips.
"Ummmffff," Sally groaned against the cuntmeat pressed hard against her mouthas she felt Marie's tongue fucking up her cunt.
Marie fucked her tongue in and out of her sister's fuckhole, faster and faster, moaning with excitement when she felt Sally's cuntmuscles grasping her tongue. Then, she pulled her tongue out and licked up and down the other girl's trembling pussylips. Then, once again, her fat tongue wedged apart Sally's cuntlips and slid inside.
"Ohhhh," Sally moaned, still tonguing Marie's pussy.
Since Sally's mouth was fastened so tightly against Marie's pussy, each little cry of lust she made went vibrating through the other girl's crotch, just turning her on even more.
Marie wrapped her hands around Sally's hips and thrust the full length of her tongue inside Sally's puckering fuckhole. She tongue-fucked her sister for long moments while Sally did the same.
As the two horny sisters tongue-fucked each other harder and faster, their pussies grew hotter and wetter and more and more juice poured into their mouths.
As they grew closer to climax, Marie pulled her tongue out of Sally's pussyhole and went to work on the girl's clit. Marie's tongue caressed and stroked Sally's stiff little clit as her sister heaved her hips.
Sally caine hard. Her long-legged body trembled as if struck with the force of an earthquake. Heat and juice exploded from her tongue-fucked cunthole as the youngster shook all over. As she came, Marie sat herself down firmly on her face, muffling Sally's passionate screams and turning her on all the more.
"Aiieeee!" Sally screamed, her shriek of ecstasy absorbed by the steaming pussy and asscheeks which firmly pressed down on her face.
Sally's entire body went rigid as she came and she bucked, thrusting her hips upward, arching her back. She remained in that position for long moments while she orgasmed.
Marie started to lift her crotch up from her sister's face as Sally's orgasm began to subside, but Sally reached out and gripped Marie's hips, holding her firmly in place.
Then, while her own pussy continued to spasm, Sally thrust her tongue out again and rammed full-length into Marie's aching pussy. Using fast, frenzied strokes, Sally fucked her sister's cunt with her skillful tongue.
"Ohhhh, God, cooommmiinnggg!" Marie screamed seconds later, as a powerful orgasm swept through her loins and a fresh flood of cuntjuice was released.
"Mmmmmm, good," Sally moaned as she eagerly and thirstily swallowed her sister's girl-cum.
As Marie's orgasm ebbed, she lifted herself off Sally's face and there was a wet suction sound as the trembling pussyflesh left Sally's juice-smeared face.
The two girls lay breathlessly in each other's arms, both of them panting for air. Their pussies continued to twitch convulsively, and rivers of thick, warm pussyjuice ran from their tongue-ravaged cuntholes, dribbling obscenely down their quaking thighs.
"Jesus, that was great," Sally said a few minutes later, her hands moving over her sister's naked, sweat-soaked body. "Do you suppose that Uncle Steve might like to lick our pussies?"
"I don't know, honey, but I sure as fuck intend to find out!" Marie said with an excited giggle.
