Slowly, painfully, Phil worked his hips off the mattress. Cumming and fucking were good for his back injury. Within seconds he was humping beneath her almost as hard as he could have if not injured, moaning as he fucked his long, swollen hard-on in and out of his mother's hairy cunt.

"That's right, darling, you fuck me so gooood!" Bucking her ass like a wild woman, Karen leaned forward so that her huge tits dangled over his face. She hefted one tit and rubbed the crimson nipple onto her son's lips. "Suck it for me, Son!" she pleaded. "Suck my nipple while you fuck my cunt!"

Phil opened his mouth wide and enveloped the stiff, crinkled cap of his mother's tit. He puckered his cheeks and sucked furiously, as if intent upon drawing milk from her enormous tits. Then he started moving his ass much faster, oblivious to his back injury, rhythmically fucking his blood-engorged hard-on into her cunt.

"Gonna cum, Phil, keep fucking me!" The bed shook obscenely beneath them as Karen feverishly fucked her pussy onto her son's cock. Her cunt was so dripping wet that the fuck juices oozed out of her pussy crack and made her inner thighs sticky with cunt oil. Every stroke seemed to go deeper into her pussy; his big prick packed her full with cock meat with every thrust.

"Cumming now!" Karen dried suddenly. The sucking pressure on her nipples and the feel of his prick fucking into her pussy seemed to merge into it's huge throbbing presence growing and burning in her belly. "Ungghh! Yes, oh shit, my pussy's so hot! Fuck it, Phil, fuck it harder! I'm cuuummmiiinnnggg!"

Phil aggravated his back injury by lifting his ass completely off the bed, ticking his cock all the way into his mother's throbbing fuck hole. Then the white load of his second cum spouted from the tip of his prick. Karen shrieked with incestuous pleasure as she felt his jism pumping her pussy to bursting with the gooey load of her son's cum.
