A feverish dampness poured into Betty's sopping cunt, and she realized dimly that she was beginning to grow very, very horny. Slowly she turned her head and regarded her son. Carl was smiling at her too. His smile was broad and happy, his eyes alive with a malicious delight. He obviously wasn't disturbed by his father's presence in the bedroom, and his massively swollen fuck meat obviously wasn't losing any of its stiffness deep inside her cunt.
Then the realization occurred to her, and the shameful blush of humiliation rapidly left Betty's cheeks. There was no reason for them to be angry with her, either of them. Both Carl and Frank had been fucking her daughter Lisa almost constantly for the past several weeks.
"I didn't mean to stop you, honey," Frank muttered. He stepped closer to the bed and folded his hands around the swelling length of his cock in his pants, staring blatantly at the lips of his wife's pussy as they wetly encased his teenage son's throbbing dick. "Why, when I walked in you were grunting loud enough to wake up the neighbors. Why don't you go ahead and finish what you were doing?"
"You want to watch me fucking, don't you?" Betty asked huskily, licking her lips lasciviously. "You want to see me fucking another man, isn't that right, Frank? Even our son!"
"That's right, Betty," Frank replied evenly. He turned slightly, winking at Carl. "Go ahead, Son. What kind of man are you, anyhow? I didn't bring you up to lie around like that. Go ahead and give your mother's pussy a nice, hard fucking. Horny women have to be satisfied, now don't they?"
Carl grinned broadly at his dad, as if the two of them were sharing a secret joke. Then he returned his complete attention to his mom's lush nakedness and the deliciously clinging folds of her gurgling hole. His hands thrust tenderly into the spongy whiteness of her breasts, milking hungrily at the milky flesh of her big tits. At the same time his ass began to hump rhythmically off the bed. Then Betty felt his long stiff tool fucking into her, reaming out her dripping pussy slit with long eager strokes of his burningly pulsing prick.
"Go ahead, Betty," Frank said coaxingly. He unbuckled his belt buckle and pulled down his zipper. Withdrawing his hardened pole, he wrapped his hand around it and eagerly began to jerk off to the sight of his wife in bed with his son. "Go ahead and fuck him. I know you want to, so go ahead! Fuck your pussy with Carl's nice big cock!"
"Oh, Carl," Betty whimpered, her eyes fluttering dazedly with her burning lust. "Oh, Carl, that feels so good… do it harder, darling, you've got such a big cock… I'm getting horny again… oh, yes… Carl… oh oh… unnhhhhh."
"Hello, everybody," Lisa said, entering the room. She pulled off her blouse and smiled mischievously, exposing the full naked globes of her ample tits. "I hope I'm not interrupting anything. You don't mind if I join in, do you?"
"Lisa!" Betty gasped.
In unison the three members of the Stanton family turned to stare in bewilderment at the pretty, horny young daughter undressing in the doorway. Then Lisa giggled, and it became obvious to all of them that she was not upset by the incredible fuck scene in her brother's bedroom.
"Oh, Daddy, you've really got a big boner, don't you?" Lisa observed huskily. Staring at the swollen knob of her dad's big dick, she kicked off her sandals and raced to pull her jeans and panties down her long tapering thighs. "I don't think I've ever seen you with such a stiff cock!"
"Get on the floor," Frank said harshly. He stared with maniacal intensity at Lisa's teenage body and fervently began to beat his meat, making his iron-hard tool throb in his fist. "Get on your hands and knees and spread your legs, so I can stick my prick in you and fuck you hard! Hurry, Goddamn it! You don't want me to cum all over the floor, do you? Hurry!"
Kicking off her panties, Lisa turned and knelt on the carpet in the dog-fucking position. Her pussy slit was dripping wantonly. She knew she had never been so horny for a man's pulsing cock in her life. Behind her she could hear her mother and brother fucking madly away, the frenzied rhythms of their humping shaking the bed all over the floor.
"Spread your legs," Frank demanded. He knelt on the floor between his daughter's thighs and grabbed her hips hard, positioning his aching cock so that the huge knob twitched toward the wet hole of her pussy. "Come on, Goddamn it, spread your legs! I'm so horny I can't stand it!"
"I am too, Daddy!" Lisa whimpered. She spread her creamy thighs far apart and let her dad fall forward, lifting her rounded asscheeks for the invasion of her dad's massive tool. "Fuck me, Daddy, fuck me hard! Please, stick your cock in me right now and fuck my pussy! Ohhhh, Daddy, I'm so horny, fuck me, fuck me!"
It was at that moment that Lisa realized her long search for a permanent cure for the burning itch in her teenage-year-old cunt was over at last. She had two of the best studs in the world right here in her own home, and she knew that between her father and brother she would be getting all the fucking and sucking she could stand for a long, long time to come.
Lisa was a truly happy girl!
