"Can I now, Mom?"

"Of course!" she giggled, feeling very depraved. "You're hard, and I already came, so go ahead and fuck my asshole!"

She held her breath as her son pulled his cock out of her cunt. Her pussy felt suddenly empty, a coolness that soothed the burning wetness of her puffy cunt-lips and sensitive clit. She held her knees tightly at her tits, her ass lifted to him, peering down at the fan shape of her pussy-hair, wishing she could see his cock slide into the pucker of her asshole. She felt so open and vulnerable that way, but it was such a lewd, delicious feeling.

"Be easy," she whispered. "Don't just ram your cock in me; go slow so it doesn't hurt."

Jerry's eyes glazed as he looked down at his mother. He saw her hairy cunt as he pushed the head of his rounded cock to her tight asshole. Her ass burned his swollen cock-head, and he pressed forward slowly, watching her asshole stretch and give.

"Be still," Debra said. "Let me do it."

Jerry stiffened, waiting and watching her asshole pushing at the head of his cock. Debra shoved slowly, feeling the pressure, but no pain. She bit her bottom lip as she pushed a little harder. She felt her asshole stretch, and hoped ass-fucking wouldn't hurt.

Jerry, feeling the pressure of her asshole on his cock, began to push inward.

"Wait!" she hissed. "Let me do it!"

Jerry was shaking with eagerness, watching the head of his cock push at his mother's asshole, her cunt above it. He placed his hands on her thighs. Debra held her breath and pushed against his cock. A soft moan came from her throat as his cock-head fucked her asshole. She paused, gasping, eyes wide.

"I have it in!" she said, pleased. "Oh, your cock-head sure fills my ass, baby! It feels like my asshole is stretched a mile!"

She lifted her ass, taking her son's cock deeper. She felt her asshole open easier now. When she had half his cock up her ass, she stopped pushing.
