"Mom! I said what are you doing?" her son said, gasping loudly.

"Your mother's suckin' my prick, dummy," Donna heard her nephew grump, and she tightened her lips and helped him slip his cock deeper in and out of them.

Donna nodded and sucked faster on Eddy's prick. Eating a hard cock and watching the big stiff one on her son excited her. Then she wished this was her son's prick in her mouth. She tried not to think it, but couldn't stop.

Suzy was jacking on Skip's big cock now, right beside the bed. With Eddy's cock fucking her mouth, seeing Suzy next suck onto Skip's prick made Donna all the hotter. She could feel her son eating up her naked ass with his wide eyes as he got sucked by Suzy. Sluttily, Donna showed her ass off to him. Her heart pounding, she bent over more, blowing Eddy, and stuck her rounded ass-cheeks up for Skip. Then she waggled her ass at his face while Suzy kept his prick bucking with her hot little mouth.

Her son couldn't resist Donna's ass. He started fingering it, felt down through its deep warm crack, cupped the soft rich ball of blonde pussy curls below. Donna shivered, grinned around Eddy's cock, pleased that her own son found her desirable. She moaned when he grabbed her cunt, jutted her ass higher for him. Then she rubbed her hot pussy down in his cupping hand. Cunt-juice soaked through her mass of golden pussy-hairs and soaked his fingers. Donna was deliberately exciting him into wanting even more of her cunt.

"Let me lick your pussy, Mom. Just let me eat it. I suck Suzy's. She comes like crazy. Let me make you come in my mouth," Skip pleaded.

Donna doubted she should go that far, until her pussy pulsed and dripped so much faster. Unmouthing Eddy's prick, she bent into the sheets on her, knees and spread her thighs. Her pussy popped wide open. She exposed every bit of it to her son's excited eyes. One hand under, she fingered her rubbery clit back at him, then fucked the finger into her cunt, thrilled by him watching.
