Shamelessly Karen started finger fucking, darting her fingers in and out, rubbing her fat little clitty while her kid brother reamed out her bowels. The combination of sensations in her pussy and shit hole soon got the better of her. Within a minute, Karen was humping as hard as she could, groaning and whimpering as she fucked her needy, horny whole onto her brother's pounding prick.

"Fuck my asshole, Jimmy!" she gasped. "My little asshole's so fucking horny! Gonna cum now! Fuck my asshole, fuck my horny little asshole! I'm cumming, Jimmy! Cumming, eiiuummmiinnngggg!" Karen humped in a delirium of orgasmic passion, torridly finger-whipping her pussy, tirelessly thrusting her stretched, squishy asshole onto his big, skewering prick. Jimmy butt fucked his naked sister as hard as he could, guiding her through the writhing violence of orgasm.

Suddenly he came down hard, moaning as he rammed his huge prick in to the hilt. A second later a tremendous load of prick juice was spouting out of his boner, making the big prick twitch and quiver up her asshole as spurt after spurt of cum sap streamed out of his big cock.

"Keep cumming, Jimmy! Keep shooting your cum up my butt!"

Her brother's orgasm lasted nearly a minute. When he finally pulled his huge prick out of her asshole, Karen's shit-sphincter felt swollen and bubbly with the welling-up load of jizz.

Jimmy flopped onto his back, gazing dazedly up at the ceiling. As horny as she still felt, it wasn't long before Karen's mind returned to her other problems.

"Jimmy, do you know how much money we have left?" she murmured.

"Neither do I, but it's not much. I gotta get a job!"

"Very pretty girl," the man was saying. He sat behind his desk with his fingers interlaced, nodding his head sagely. "Yes, that's what you are. A very, very pretty girl!"
