"Bob, has anyone ever kissed your cock?"

"Kissed my cock?" he asked, shaking his head. "No."

"Not even Pamie?"

"We just fuck. Mom, that's all."

"And you don't come in her little cunt, either, do you?"

"She said not to."

"I wonder why?" Susan said, jacking up and down on his cock watching the head and shaft become smeared by the dripping fuck juices. "Did she say?"

"No, it's just the way we fuck."

"Don't you want to come in her little pussy?"

"Sometimes it's hard to jerk out in time, Mom."

Susan chuckled. "So that's why you say I'm a good fuck, because I let you come in me?"

"Yeah!" he grunted, fucking his cock into her fist.

They were silent for a while, with Susan gazing at his cock. Bob's hand rested between her thighs. Susan shivered and pulled in a deep breath of air. Suddenly she dipped her face, pressing her moist lips to the head of her son's cock. Bob gasped, his eyes shooting wide as he watched.

Susan had intended only to kiss the head of his cock, but the familiar heat, the wet fuck juices seeping from his pies hole forced her to open her lips, sliding them around the smooth cockhead. Her husband had loved to be sucked, and Susan found a hot, hard, throbbing cock in her mouth a treat. She lapped her tongue over her son's seeping piss hole, tasting those fuck juices. A fire started in her cunt and she slipped her lips lower, thrilling at the stretching sensation, the way Bob's cock filled her mouth. She held half his cock between her lips, sucking gently, her tongue twisting, then she pulled up, smacking her lips as his cock came free.

"You like that?" she whispered, pumping his cock again.
