What had she just done! It seemed incredible to her that she'd just yielded so utterly to the longings of depravity, the shameless urge to go down and suck the hard cock of her own brother. But it was done now, and Jimmy obviously wasn't the least disturbed at having had incestuous contact with his own sister.

And God, was her pussy wet! The crotch of her bikini panties felt like it was simply awash with fuck juice, and her cunt hole felt more hot, swollen and tingly than it had in years.

Suddenly Karen pictured herself fucking her kid brother, lying on her back with her legs wrapped around his waist, humping her ass off the carpet as he hammered that long, fat pussy pleaser of his up her cunt again and again. The image was incredibly arousing. If she'd been excited before she'd started sucking his cock, she felt even hornier now.

"Man, that sure was a good cum, Sis," Jimmy groaned happily. "I never thought anyone could suck cock like that. You're a real pro!"

"But I guess I didn't do a good enough job, Jimmy. Your boner's still stiff."

Again Karen wrapped her fingers around his cock shaft, jacking it lightly up and down. Jimmy grinned as he realized his sister wanted more sex.

"Have you been fantasizing about that for a long time, Jimmy?"

"Fantasizing about what?"

"About me sucking your dick for you. Your own sister. You liked getting head from me, didn't you? I'll bet you've fantasized about me plenty of times in the past, too. Am I right?"

"Yeah, you're right," Jimmy admitted, and smiled more happily than ever.

"It's 'cause of my body, isn't it?" Karen asked, gesturing at her giant titties. "I guess I can't really blame you, Jimmy. Lot's of men want to fuck me. It's not my fault that my tits are so big, and it's not your fault that I make you horny, is it?"

"Not at all."
