"Does this feel good, baby?"

Donald just moaned. His cock throbbed violently in his mother's palm, growing even stiffer. Soon more and more cock juice oozed out of his piss hole, coating his mushroom cock head with a lurid slime of wet, salty precum.

"Oh, Donald, look. I'm making it leak," Vivian observed breathlessly. "I'm making your cock leak fresh cum."

Sighing with incestuous desire, the naked mom started beating her son's cock meat as hard as she could. Now the cock sap, bubbled heavily out of his prick, running down the cock shaft to coat her fingers and palm with a lubricating sheen of pre-cum.

Vivian's big tits swung heavily over the youth's stomach. Her pussy steamed with new fuck passion as she raced her hand in a blur up and down her child's luscious boner. Now her mouth was watering. She simply had to give her boy a good, long blow-job.

"Donald, I'm going to put this big cock in my mouth now," she admitted shamefully. "And I'm going to suck it for you, and I'm going to drink your jism. But…" Vivian thought quickly, trying to make up an excuse for her obscene behavior, no matter how absurd. "But it's just to help you get to sleep. It can never, ever happen again between us. Especially not with Lana and Richie living with us. What if one of them caught me sucking my own son's cock?"

Donald didn't speak.

Shamefully, Vivian lowered her head. She slid her hand to the root of his steely prick, holding it in position, so his cock wouldn't twitch and throb away from her mouth. Vivian flicked out her tongue and ran it across the shiny-skinned tip of her teenager's cock meat.

His cock juice tasted delicious. Vivian slid her tongue avidly over and around his piss hole, making obscene little slurping noises as she licked up the oozing pre-cum.

"Suck it for me, Mom!" Donald gasped, twining his fingers into her thick, blonde hair. "Oh, fuck, I've really got a hard-on now! Suck the cum out of my prick!"
