She lifted her skirt to her waist, revealing the creamy swells of her naked ass in the mirror. Marty turned his eyes toward the reflection, watching excitedly. He saw his mother's naked ass cheeks while she began to pump her ass up and down, her hairy, very tight cunt riding on his cock.

"Hold mother's ass, baby!" she mewled as she churned her naked hips about. "Ohhhh, honey, grab my ass in your hands and squeeze it! I love my ass being held and squeezed when I fuck this way! Grab mother's hot ass, darling!"

Marty's hands dug into the tight smoothness of her naked ass, holding on, his fingers almost in the hot ass crack. Joan turned her head so she could watch, too, and they both gazed with burning eyes while her naked ass thrashed up and down.

"That's beautiful, baby!" she whimpered as her ass plunged, the ass cheeks tightening and bunching. "That's so beautiful… watching us fuck! I love it, Marty! Oooo, I can feel your sweet cock all the way up my cunt! See mother's ass, darling? See how mother's naked ass fucks that cock! Oooo, I love you so much, love your cock up my pussy, Marty!"

Joan's cunt was nibbling again, sucking on her son's hard cock for the second time. She was clutched by a series of burning orgasms as usual. The tightness of her cunt seemed to be even tighter than ever, flexing on Marty's throbbing prick as she pumped up and down. From the waist up, Joan was almost perfectly still, but from there down, her body was a dynamo of intense action.

As her orgasms increased in strength, she began to wail loudly, her ass pounding furiously. She raced a hand behind her banging ass and clawed at her son's hairless balls. She pulled them against the cheeks of her ass, trying to shove them into the hot ass crack. Her son was grunting and gasping as he lifted his hips up, fucking his cock as deep as he could into that devouring, steamy pussy. Joan's body was shaking with the intensity of her orgasms, and her mind was reeling with the ecstasy flooding her overheated body. Sparks flew about inside her, setting off explosions of such erotic pleasure that she was afraid she would melt or faint. And Joan didn't want to faint because she would lose the feeling of her son gushing that sweet, precious come juice up her hungry cunt.
