"Be gentle, Son," she mewled as she felt his spongy cock knob pushing onto her ass opening. "It's been a long time since Mom got her asshole fucked!"

Donald stared down at the crevice of her ass, seeing her tightly-muscled sphincter stretching open around the head of his cock. Instantly he felt the rubbery pressure of her ass channel convulsively sucking and milking his prick.

Donald started fucking, boring inch after inch of his stiff cock into his mother's clutching asshole. Vivian's face contorted with assfucking ecstasy.

"Yes, baby, yesss!" she hissed, reaching behind her back and grasping her ass globes, spreading her blushing buns to help her son fuck his cock deep inside her ass.

Donald lay flat on his mother's back, fucking wildly. Soon every inch of his meaty prick was enveloped by her tight, rubbery, squirming asshole.

"Unngghhh! Oh, fuck, what a huge cock!" Dazedly, Vivian writhed to meet his strokes, fucking her burning asshole onto his cock. "Ahhh, Goddamn, your prick's all juicy, baby! It's juicy from my pussy! Oh, fuck your cock feels so good up my ass!"

Donald increased the intensity of his fucking, more brutally plowing his cum-swollen prick in and out of her churning ass guts. Vivian's lips curled in a lurid smile of sexual contentment. She thrust her hand under her undulating belly, groping her cream matted pussy curls until she found the drippy opening of her cunt.

Feverishly, the mother finger-fucked herself, darting her fingers rapidly in and out of her pussy, rubbing her clit under her thumb. Her asshole spasmed and contracted uncontrollably, wetly sucking the hammering length of her son's cock.

"Fuck your mother, fuck your mother!" she gasped. "Oh, Donald, you fucker! I'm cumming, baby! Fuck me good, precious! Fuck my asshole! Cuuummmiiinnngggg!"
