Hurriedly, Bobby shoved, his pajamas to his feet, and Donna's pulse raced as she saw her son's naked body. His cock was so strong, so hard, with those precious balls dangling below. His ass was as small as Kathy's, but looked much tighter, more muscular.

Kathy's head was lifted again, her blue eyes looking down between her thighs as Bobby moved his cock toward her cunt. Donna, too, was watching, holding her breath. She saw her son brush the head of his cock up and down that sweet pussy slit. Kathy cooed with delight as Bobby rubbed his dripping cock along her cunt.

"Golly, you feel hot," Bobby said, his voice thick with desire.

"I'm supposed to be hot," Kathy replied. "At least I am down there. My pussy is always hot, and I bet I can always make your cock hard, too."

Bobby giggled nervously and Kathy made a happy gurgle as she lifted her cunt a bit.

"You stick it in me now," she said.

"What if I come?" Bobby wanted to know. "I might come before I know it."

"That's okay," Kathy said. "If you come, just come, that's all."

"Will you let me do it again even if I come fast?"

"We can do it all the time," Kathy said. "Besides, I like it when a guy comes in me. It makes my pussy feel good."

"Okay," Bobby replied. "I'm gonna put it in you now."

"Ooooo, do it!"

Donna, her legs shaking, watched her son slip the swollen head of his cock into Kathy's cunt. As his prick slithered between those boiling wet cunt lips, Kathy gave a soft sob of ecstasy. She rested her head back on the table. She held her crotch up, though, and Donna could see her son fuck the full length of his cock into that hot little pussy.

"Pump your ass!" Kathy yelped. "Now you gotta pump your ass and fuck me! Oooooo, you sure feel good inside my pussy, Bobby! Come on… you gotta fuck me now!"

Donna could hardly breathe as she saw her son's cock fucking in and out of Kathy's cunt.
