"I think you're right, Billy," Tony said. "I think you made her come." Lynn's orgasms slowly receded, but when Tony pulled his finger out of her cunt, with Billy taking his out of her asshole, Lynn felt herself come again, although it was a mild orgasm and nothing like the boiling one earlier.

The boys stood behind her, looking at her naked ass and thighs.

"I think Lynn is bullshitting," Billy said. "I think she likes being tied up."

"Sure looks like it, Billy. Do you think she and Dad do it this way?"

"Maybe," Billy replied. "But I can't see Dad being that brave with a woman."

Tony's, cock continued to throb outside of his pants. He was standing close to his stepmother, and he began to rub the seeping head of his cock against her thigh, then over the cheek of her ass.

"What are you up to, Tony?" Billy asked.

"Nothing, just rubbing my cock on her, that's all."

They talked about her as if she wasn't there. Lynn's embarrassment was more pronounced because of it. She was just a plaything for them.

"Let's piss on her fucking ass," Billy said. "Oh, no!" Lynn screamed. "Don't make me ashamed any more! Don't do it, please!"

"I can't piss with a fucking hard-on," Tony said.

"Then I'll do it!" Billy replied, taking his cock out of his pants. His prick was half hard. He shoved it up to his stepmother's creamy naked ass, sliding it into the hot crack between her cheeks.

Lynn held her breath. She tried to clench her ass cheeks, but all she succeeded in doing was squeeze the head of Billy's cock. She quickly relaxed.

Billy slipped the head of his cock up the hot crack of her ass, laughing as he let loose with a stream of piss, soaking her asshole.

"Oh, God!" Lynn wailed, feeling his piss stinging her asshole.
