"Mmmm, lick my nipples again, darling," she murmured, drawing his mouth to her tit. "Your tongue makes them tingle."

She trembled as he ran his tongue about her nipple, making it stand up very hard. While he sucked her nipple into his hot mouth, Marilyn slipped her hand to his cock and balls. She cradled Donny's balls in her palm, enjoying the feeling. She felt his cock swelling along her wrists, and moved her fingers about it.

She pumped his prick slowly and firmly, thrilled when it throbbed in her fist. She used her other hand to hold his mouth tight on her tit, his hot breath fanning her flesh. She squeezed his cock, mewling in pleasure. Her son grunted when her fingers tightened about his prick and she felt him moving his hips, pumping with her fist.

"Do you want to do it again, Donny?" she asked in a breathless voice, squeezing his cock harder. "Do you want to do it to me again?"

Donny lifted his mouth from her nipple, his eyes gleaming with eagerness. "Can we, Mom? I sure would like to."

"What about your 'sort of' girlfriend?" she teased.

"Who needs her?" Donny mumbled, sliding his hands down to the bush of her cunt. "I've got you."

With a low laugh of delight, Marilyn rolled onto her stomach, shaking her naked ass. Donny gripped his mother's ass with both hands, digging into the firm cheeks and making Marilyn coo with pleasure. She wiggled her ass up into his hands, then drew her knees beneath her body.

"Do it this way, baby," she urged hotly, shaking her uplifted ass wickedly. "Do it to me this way, honey."

Marilyn arched her creamy, shapely ass high into the air, resting her head on the carpet, arms above her head. She parted her knees for him. Lifting her head, she looked over her shoulder as her son knelt behind her ass.
