"That feels good, Uncle Bob!" Eagerly Sally ground her big tits on the sheets and pumped up her pussy mound for more fingerfucking. "Play with my cunt harder!"
"Goddamn, Sally! You've really got a tight little snatch!"
Sally shrieked and turned her head at the sound of the unexpected voice. Standing beside her bed, grinning down at her happily, was her big brother Phil! All he had on was a pair of white cotton shorts, and the fabric was stretched obscenely around his enormous prick, wetting the front of the shorts with oozing cum.
"Phil!" Sally gasped. "What are you doing here?"
"I got horny," Phil replied. He held her wriggling ass down with his left hand and inserted another finger into her burning, dripping cunt. "You must know Dad caught me fucking Mom. I guess if I can fuck her I can fuck you too!"
Sally was about to protest, but she was extremely horny, and her brother's fingers felt very good burrowing into her pussy. In spite of herself, she soon found herself groaning again, humping on the pillow.
"And I guess you been fucking Uncle Bob too," Phil murmured. "Don't worry, Sally. I won't breathe a word to anyone!"
He grabbed her hips and turned her over, sighing at the sight of his younger sister's big stiff-nippled tits and the fleecy brown-haired triangle of her hot pussy. Then he climbed onto the bed with her and knelt between her soft thighs, his massive hard-on jerking lewdly in his shorts.
"Don't, Phil," Sally whimpered, covering her pussy slit with her hand. "I don't want you to fuck me. I'll be a whore if I fuck you and Uncle Bob at the same time."
"You won't be a whore, little sister," Phil whispered hoarsely. "Fucking's good for you."
With that he leaned forward and buried his head in her crotch, inhaling the cock-stiffening aroma of his teenage sister's dripping cunt.
"Aw yes, Phil, yes!" She grabbed the back of his head, grinding her pussy onto his lips. She humped and wiggled her ass off the bed and spread her legs as wide as she could. "I can't help it! Suck my pussy! It feels so good!"
