Both froze.

Mike's cock was all the way inside her wet pussy now, every hard inch of it. Donna's body shook with ecstasy, and she pulled her hand from between their bodies and placed it back on his ass. She held her son's ass with both hands tightly, and very slowly moved her hips.

Mike moaned.

Donna gave a soft cry of delight.

She moved first, lifting her hips and lowering them, sliding her cunt on his cock. Then Mike was moving, stabbing his cock into her cunt slowly. They kept staring at each other, both slightly startled at what they were doing, neither wanting to say anything right now.

Mike fucked his mother slowly, letting her set the pace.

Donna humped in almost slow motion, feeling her son's cock sliding along the gripping, fiery lips of her cunt. She could feel her clit scrape at his hard cock-shaft, and she breathed hotly. They moved in perfect unison, with Mike pushing his cock down as she lifted her crotch. The delicious filling of her cunt caused shivers to run up and down Donna's flesh. She closed her thighs tightly again, feeling her son's cock stabbing up and down. She moved her hips, holding his ass, her upper body still. Her eyes burned into his, and she ran her tongue over her lips as the sensation of ecstasy grew.

Donna's hips speeded up, and Mike went along with her. He had his elbows against her shoulders, his hands in her hair. Donna clutched his bunching ass-cheeks tightly, arching her pussy upward to meet his cock. She spread her legs, and Mike shifted his between them. She scissored her satiny thighs along his, her hips twisting and grinding as his cock pumped into her cunt.

They breathed hard and fast, the rapture swelling in them both. She felt her son's cock throbbing inside her cunt, and the hairy lips grabbed at it tightly, making Mike groan. She squirmed her cunt upward. Her eyes were dreamy, almost unseeing, and Mike kept looking down into them, his own burning as hot as his cock felt to her. As the ecstasy increased, so did their movements.
