Jimmy just smiled. Karen was on her knees and elbows on the center of the bed, naked, her huge, spongy milkers swaying pendulously over the sheets. She grimaced, biting her lip as she felt Jimmy's hand moving between her ass cheeks.

Jimmy was lubing up her asshole. He held an open jar of lubricant in his hand, was busily smearing the thick, yellowish jelly on the pink, puckered ring of his big sister's shitter.

All night long he'd fucked her pussy, shooting load after load of cum juice into the buttery depths of Karen's well-reamed cunt. As the fuck sessions had continued into the wee hours of the morning, the busty brunette had noticed that her rubbery little asshole tingled and itched more and more when her brother was laying the pipe into her pussy.

Now she wanted him to fuck his big boner up her shit tunnel too. So she was willingly submitting to the preparation for sodomy, grimacing as he slid his fingers up her shitter to lubricate the interior of her asshole as well. Now that she'd gone this far, she felt eager to sink to the lowest levels of depravity with her hung, horny brother.

"Okay, that's enough, Jimmy!" she pants! "God, my asshole's really throbbing something fierce now! Go ahead and fuck it, Jimmy! Fuck my horny asshole just as deep as you want."

Karen grabbed two pillows, thrusting them under her belly sprawling on top of them, thus elevating her hips. Shamelessly she reached behind her back, digging her fingers into her round little ass checks and spreading them wide apart, openly revealing her red, horny asshole to her naked kid brother.

"Fuck my asshole, Jimmy! Hurry, lover, my asshole wants your big dick!"

Jimmy mounted her, holding his cock in his fist, aiming the swollen tip at her rubbery shit orifice. A moment later, Karen was posing and grimacing as she felt the giant cock shaft plowing into her, stretching her tender shit-sphincter to the bursting point around the invading thickness of his prick.
