Tracy's eyes became moist with desire as she saw it, and Susan's mouth watered heavily, her tongue flicking about her lips.
Tracy lifted her hips and peeled her panties away, throwing them onto the couch. She jerked her short skirt to her waist, spread her legs as wide as possible and held her arms to her brother again. Susan lowered her gaze to her daughter's glistening wet cunt, then to her son's cock again. Her pulses were racing with erotic emotion, eager to watch them fucking again.
Bill, his eyes straining hotly at his sister's cunt, stepped between her spread legs, his cock lurching up and down, dripping from the pisshole.
"Honey," Susan said in a throaty voice, "take your pants down. We want to see you naked, see everything naked."
Bill opened the waist of his pants and shoved them down, kicking them from his feet. Susan lifted herself to one elbow, taking her son's hard cock in her hand and stroking it as her daughter gazed up with hot eyes, her hips twisting. Bill watched his mother's hand on his cock, tried to see her cunt again, and finally stared down at his sister's hair-trimmed pussy. Tracy rubbed lightly at her swollen clit as she watched their mother slowly fondle Bill's cock and cup his balls.
"Ooooooh, be careful, Mother!" Tracy gurgled hotly. "He's so hard, you might make him come before he gets his cock in me! Be careful!"
Susan giggled softly, squeezed her son's cock and released him. "Fuck her, Bill," she said in a husky voice. "Fuck your sister, baby! Ohhhh, put your sweet cock in her cunt and fuck her! Fuck her, fuck her!"
"Yes, Bill!" Tracy hissed, rolling her hips as she shoved her cunt into the air. "Fuck me! Oooooh, fuck me, honey!"
Bill went to his knees, starting to plunge his cock into his sister's wet and fiery cunt. But Susan placed her hand on his lower stomach, and he sat on his heels, looking at her, puzzled.
"Let me watch your cock when you put it in Tracy," Susan mewled, taking the base of his cock in a forefinger and thumb.
Tracy squirmed her cunt forward, her legs sliding past his hips as she scooted her creamy ass up on his thighs. Susan pressed her son's cock down, sitting up to watch Tracy's wet cuntlips stretch around the head of her son's cock. She moaned softly, watching with erotic interest as Tracy's cunt slipped slowly onto Bill's prick, the lips spreading, her tiny clit inflamed and throbbing. Tracy's cunt hair brushed against Susan's fingers, then the girl's searing and stretched pussylips touched Susan's hand.
"Ooooooh, sweet," she whimpered, leaning over to look closely at her son's cock stabbing into his sister's boiling cunt. "Oh, God! That's so fucking sweet! Fuck, both of you! Please, I want to see you fuck each other! Oooooh it makes me so… so hot, seeing your beautiful cock in that hairy, wet cunt, Bill! Fuck her pussy, baby! Fuck your sister's hungry cunt!"
Susan, still holding the base of her son's cock with her thumb and forefinger, brought her other hand to Tracy's trembling stomach, sliding it through the silky hairs and shoving two fingers along her puffy, stretching cuntlips. Tracy mewled in pleasure, her hips grinding, her cunt filled by her brother's throbbing cock. Bill, still sitting on his heels, gazed at his mother's hands and sister's cunt. He watched in delight as his sister began fucking him this way, jerking her hips up and down, riding his cock with wet heavy, banging against his mother's fingers, which were still on the base of his prick. This position did not allow Tracy's clit to rub and scrape on the shaft of his cock, but Susan was making up for that. She was rubbing swiftly at the girl's tiny, swollen clit with two fingers, almost sobbing in voyeuristic ecstasy.
Tracy clawed at her swollen tits, her head rolling and twisting on the floor, her hips beating wildly now on her brother's cock. "Fuck me! Ohhhh, Bill, fuck me! I love it, baby! You're so fucking hard… I love your hard cock! Fuck my cunt, honey! Oooooh, fuck me deep!"
Bill slipped his palms up and down his sister's slender thighs, his eyes huge and hot as he watched her tight, sweet cunt fucking his cock. The fact that his mother was there watching, actually helping and urging him to fuck Tracy, made it all the more intense and pleasurable for him. Bill knew how good it felt to be watched as he fucked his sister, but it felt even better because it was his mother watching them. Running his hands up and down his sister's thighs, his right hand brushed his mother's knee. With a sudden squeal of delight, Susan grabbed his wrist and she pulled her son's hand between her legs, curling his fingers into her steamy cunt.
"Feel me, honey!" she groaned. "Bill, feel my cunt! Play with mother's cunt and fuck your sister's cunt and feel me up and fuck Tracy and…"
Bill, felt the heat of his mother's cunt against his palm, the slippery wetness seeping from her puffy pussylips. Still sitting on his heels, watching his sister's cunt fucking in a frenzy on his throbbing cock, he rubbed his mother's pussy hard, shoving two fingers into it and thrust them up and down. Susan rose to her knees, spreading them wide so her son could plunge his fingers into her cunt. She pushed Tracy's hands away from the girl's firm tits and, with a quick movement, shoved the light sweater to Tracy's neck. Since her daughter was not wearing a bra, her succulent tits were beautifully naked, the tips standing rigid.
Bill was so excited, his gaze darted from his sister's pussy, fucking on his cock, to his mother's hand as she began to feel and fondle and squeeze Tracy's tits. His two fingers banged deep and hard up his mother's bubbling cunt, fingerfucking her with excitement. His hips shook and be started to fuck with his sister, driving his cock into her as she wiggled down onto, him. Her ass felt so good on his balls, rubbing and brushing them, and her cunt was so hot and wet and tight, gripping the head of hiss cock hungrily, as if afraid he would pull it free.
Tracy, once more gripping a tit, flung her hips about in a wild manner, squealing loudly as her mother squeezed and twisted the nipple of her other tit. Bill's mind was reeling with ecstasy, the pleasure of fucking his sister with his cock and fingerfucking his mother at the same time an intense experience.
Then Tracy became even more erotic. She lifted her legs high in the air, grabbing behind her knees and pulling them to her tits. This caused her ass to go high in the air, and Bill had to pull his hand out of his mother's cunt to lift himself up. Otherwise his cock would come out Tracy's cunt.
With his sister's ass high, her knees against her shoulders, he had to almost stand up to fuck her. Susan moved quickly behind her son, shoving her face close, watching his cock fuck Tracy's pussy this way. She saw the girl's hairy cuntlips clutching at Bill's stabbing cock, the wink of her daughter's tight asshole. Bill was fucking his sister energetically now, his sweet balls bouncing up and down.
The moist sounds of them sent tremors of erotic ecstasy through Susan's heated body, making her cunt pulsate. If only she could get her son's cock inside her mouth now while all that delicious cunt juice was smeared over it, she would suck her son's cock off frantically. Her cunt exploding as she sucked up her daughter's pussy juice as the thick sweetness of her son's come at the same time.
She shoved her hands beneath her daughter's lifted ass, helping to brace Tracy, her eyes gleaming as she watched her son's balls beat upon her daughter's puckered asshole. She held her hand beneath his balls, feeling them slap into her palm. She sobbed with intense pleasure, licking her lips as she started to twist and tug on Bill's balls.
"Go deep, Bill!" Tracy squealed, shaking her ass about lewdly. "Fuck me real deep, baby! Ooooooh, what a cock! So fucking hard… so hot, and you're about to make my cunt really come off! God, do I love to fuck you, Bill!"
"Give it to her hot cunt, Bill!" Susan urged hotly, pulling her hand off Tracy's creamy ass and starting to squeeze her son's ass, while still clinging to his balls. "Fuck your sister! Fuck Tracy's hot, wet cunt with your sweet cock! Oooooh, darling, shoot it to her… come in her fucking cunt! Squirt that sweet, sweet come in your sister's hungry pussy!"
