She lowered her head, looking between her tits, watching his balls swing back and forth as his cock darted in and out of her cunt. Each inward fuck-thrust into her pussy forced her breath out in a hot gasp of delight, making her tits sway. Her nipples strained with a tingling hardness. The fleshy slap of his body against her naked ass sent hot tremors racing up and down her spine. Her cunt was so sensitive that she could feel each throbbing ridge of her son's cock. The head of his cock expanded, caressing the steamy tissues deep inside her pussy. With moaning cries of rapture, she churned and pumped her ass with him.

Johnny, panting hotly, watched his mother's asshole pucker as he pounded into her cunt. The tight fit of her pussy stroked and clung to his prick.

No matter how tight he held her hips, Lisa could wiggle them energetically. It felt to her as if his cock penetrated her cunt all the way to her throat. It was the reason she loved to be fucked in this position – he could go so much deeper into her.

With throaty, hot sobs, she whipped her naked ass around and around with wanton motions.

Johnny seemed to fuck her cunt with fantastic speed, the friction making her mind spin with lewd ecstasy. His balls bounced off her swollen clit, increasing the growing beat.

"Ohhhh, Johnny, Johnny!" she gasped. "Ahhhhh, Mom!"

"Oh, baby! Oh, God, Johnny! My cunt… you're burning mother's cunt up with that hard cock!"

"Mom, what are you doing?" Johnny gasped.

"Fucking you!"

"No, your cunt! What are you making your cunt do?"

"Nothing! I'm not doing anything with my cunt!"

"But it's squeezing me, Mom! Your cunt is squeezing my cock! If you don't stop that, you're gonna make me come too fast!"

"I'm not doing it!" Lisa wailed. "It's doing it by itself!"

"You'll make me came, Mom!"

"Come!" she cried, straining hard against him.
