"Or me," Julie whispered. "Piss on me, if you don't want to piss on your sister."

"It was Becky who pissed on me, Mom," he said. "Why would I want to piss on you?"

Julie's eyes took on a hot sparkling glow. She twisted her hips, grinding one heel into the crack of her ass, opening her knees wider so the full expanse of her cunt gash was exposed. The tip of her throbbing cunt peeked out from the juicy folds of her pussy.

"Maybe… maybe I'd like for you to piss on me," she said, her voice so low it was almost inaudible.

Becky was watching her mother, her blue eyes questioning. She still sat demurely hands folded in her lap, knees together. Ben was staring at his mother, and. Julie was twisting her hips invitingly, her cunt glistening wetly. Her tits swelled up in round sweetness, nipples half an inch long and tingling in hardness.

"Well, Ben?" Julie urged.

"Mom, are you sure?" Ben asked, his voice coming out from high to low, cracking in a squeaking sound.

"I wouldn't ask you to if I wasn't," Julie said, moaning softly with anticipation. "Maybe you'll make me come again. It might be fun, and my pussy might come again."

"But the couch…"

"Fuck the couch!" Julie panted. "We can buy a new one."

Ben stood up, still unsure.

Julie gazed at her son's cock, trying to imagine what it would feel like when his hot piss sprayed onto her. Becky's eyes were enormous again as she watched, hot excitement glowing on her young, pretty face.

"Me you gonna really let him piss on you, Mother?" she asked.

"If he will," Julie replied.

Ben started grinning from ear to ear. "Okay, Mom," he said, taking hold of his cock. "But remember, you asked me piss on you. Don't get mad at me later."
