Tony grinned as he guessed what his mother wanted, his cock pulsing eagerly between her fingers. "A couple of times."

"Oh, that's good," Sylvia sighed. "Tony, please, baby, would you fuck my asshole for me? I know it's awful. It's just so horny, lover. I really need a good ass-fucking, honey. I need it awful bad."

Tony smiled. "Get on the bed, Momma."

"Oh, Tony!"

Swiftly she crawled back onto the mattress, her asshole tingling and burning in anticipation of his cock. She leaned across the bed, opened the nightstand drawer, and withdrew a little jar of Vaseline. She handed it to her son, then sprawled on her stomach on the bed, thrusting a pillow under her hips.

Oh, fuck, her asshole was so hot and itchy! Sylvia reached behind her back, digging her fingers into her round, plump, mouthwatering ass. Then she spread her ass-cheeks wide, revealing her puckered asshole to her son.

"Lube it up, Tony!" she panted. "Hurry, son, hurry!"

Tony uncapped the jar, smearing the Vaseline heavily on his staining prick. Sylvia shuddered as he pasted it on her rubbery shit-opening, thrusting one, then two lube-coated fingers deep inside her asshole. Sylvia's shit-muscles sucked eagerly around his fingers, and she realized that she would have had to spend the whole day jacking off her asshole if Tony hadn't agreed to fuck her up the ass.

"That's enough!" she panted. "Fuck Mom's asshole right now, Tony! Hurry, baby, Mom needs a big cock up her ass!"

Tony swiftly mounted his naked, horny mother, aiming his dripping cock-head at her throbbing shit-opening. Sylvia bit her lip, grimacing as her muscular sphincter stretched to bursting around the invading thickness of his cock. Then the grimace turned into a wanton gasp as she felt his massive cock plowing into her asshole, inch by inch, invading her tenderly sucking bowels.
