Tom Allison: Dental assistant on top

Karen gurgled as she clung hungrily to big, squirting pisser. She kept sucking and jacking his cock as hard as possible, now working her throat muscles to gulp down the load at the same time. For at least a half-minute straight, her kid brother's boner kept spraying cum down her throat, Karen sucked out every drop of it, refusing to let her kid brother's boner slide out, of her mouth until she'd licked the last traces of cream from the head of his cock.

Then the cock sucking was over. Jimmy sprawled back on the couch, his spit-glistening boner remaining as hard as ever as it twitched and pulsed over his stomach. Karen sat back on her heels and blushed with shame as she licked the stray drops of prick juice from the corners of her mouth.

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."

"Would you like to look at my naked body now, Jimmy? As long as we've gone this far, I guess we might as well do everything else."

Jimmy just smiled. Her cunt throbbing and juicing, Karen wiggled out of her sweater, exposing her sleek belly, and, then the melon stuffed cups of her lacy white bra. She popped open the front clasp, shrugging the double D-cup undergarment off her shoulders and it drift to the floor. Now her enormous, nippled milk makers were completely exposed to her young brother, with the teats crinkled and stiff with her need for relief.

"They really are big, aren't they, Jimmy?" Karen cupped her enormous tits, rolling and kneading the mammoth tit-melons under her hands. "You'd like to play with them too, wouldn't you?"

"Yeah!"

"Then I guess you better get on the floor with me!"

Karen stretched out on her back, her huge tits rolling and jiggling with the movement, looking up at her kid brother expectantly. Jimmy slid off the couch and joined her on the carpet. He went straight for her slacks and shoes, tugging them both off, until she was naked except for her panties.

"Shit, Sis! Your pussy's really dripping!"

Her cunt was so wet that the panty crotch was dripping, stuck to the curly-haired lips of her hot, swollen, ready for fucking cunt. Karen raised her hips, helping her little brother as he pulled off the panties, exposing her bare pussy triangle. Then she was completely naked, lying there on the floor with her tight little cunt throbbing and burning, the pungent smell of her wet pussy filling the whole apartment.

"Shit, Karen, you really need it bad!"

He splayed her thighs apart, staring at the juncture between them, at the pouting, swollen lips of her horny, aching slit. Then Jimmy shocked her. Karen had thought that he'd want to nurse on her giant tits first, as most men did. Instead Jimmy immediately sprawled on his stomach between her legs, facing her wet pussy hole, moving forward until his lips were pressed on the sticky wetness of her cunt.

"Unngggh! Oh, Jimmy? I didn't know you were a pussy licker… ungggh! Oh, little brother!"

Her words trailed off as Jimmy started sucking and licking, hungrily pressing his mouth on her creamy fuck opening, sluicing the flat of his tongue up and down between the flowering folds of her cunt.

"Oh, fuck!" Karen panted. The naked, busty big sister automatically spread and cocked her thighs as wide and high as she could. Then she started wriggling and humping her naked fanny off the carpet, her huge tits jiggling spongily, groaning and gasping and eagerly fucking her wet, itchy pussy onto her kid brother's lips.

"Feels good, Jimmy!" she panted, "Unngggh! Oh, yes, suck my pussy, little brother! Uh, unh, ungh, suck my horny cunt."

Jimmy pushed his hands up, delicately peeling open her pussy petals with his fingers. Then he started licking and sucking even more avidly, on her pussy interior, on his eagerness to suck all the hot, faintly fishy smelling cunt cream from the folds of her twat.

"Unngggh! Oh, Jimmy, Jimmy!" The harder she bucked her ass off the floor, the more her big titties quivered. "Lick my clitty now, Jimmy! Oh, suck it, suck it, put it between your lips!"

Jimmy obediently started concentrating on her fat, protuberant little clitty, and the expertise with which he licked it showed Karen that he'd had more experience with sucking cunt than she'd ever dreamed. Tenderly he pushed the sensitive bud from side to side with the tip of his tongue, making her gasp and whine as the fuck need built rapidly in her cunt.

Jimmy straightened two fingers, gooshing them into the narrow, tightly-gripping interior of her pussy. Karen started humping much harder as he pumped the fingers rapidly in and sat, jacking off her throbbing pussy, working on her aching clit.

"More!" Karen pleaded. She clutched her kid brother's head with both hands, urgently humping her naked ass cheeks off the floor. "Gonna cum now, Jimmy! Unh, getting close! Suck my pussy, suck my horny pussy! Unh, making it cum!"

Jimmy glued his lips to her swollen clit, sucking it as if it were a tiny cock. Rhythmically he punched his fingers in and out of her fuck hole, giving her pussy lips something to suck around. He flattened his tongue on the underside of her cunt and started lapping with the smooth, up and down strokes, until his naked big sister was whining and gasping, humping her ass off the carpet in a frenzy of incestuous lust.

"Nuuunggggh? Oh, fuck, so horny! Lick my pussy, lick my horny little pussy! Jimmy, I'm cumming now! Suck your sister – I'm cumming, cuuummmmggggg!"

Violently her throbbing, hairy fuck hole burst into orgasm, oozing juice onto her brother's fingers, her clit throbbing and pulsing uncontrollably between his lips. Jimmy kept his mouth and fingers exactly where they were, guiding her through the ecstatic, indescribable fury of orgasm. It was only after the spasms had completely subsided that he raised his head, licking the cunt cream from his mouth and smiling up at his sister in leering victory.

"Jimmy, fuck my cunt right now!" she moaned shamefully. "Please, Jimmy! My pussy is so wet! I don't think I've ever felt this horny before! Just lie on top of me and fuck the shit out of me, Jimmy! My pussy needs a good, hard fucking awfully bad!"
