"You certainly are nervous, Randy. None of the other boys are that nervous. Something really is bothering you. Don't I turn you on, Randy? Aren't I good enough for you?" she teased.

"For Christ's sake, Lisa, you're good enough for me all right! You're good enough for any guy. But.. " he struggled.

"Am I as pretty as Sherry?" she suddenly whispered in his ear.

"Sherry!?" he gasped, his heart skipping a beat. 'What the hell?"

Randy had had no idea that Lisa even knew his sister. And now she was mentioning her name casually while she stroked his hardened cock. There was something hidden in the tone of that soft whisper, something that made his confusion even more complete. It was as if Lisa were getting at something, as if she were insinuating something with the mere tone of her satiny voice.

"Is something the matter, Randy darling?" Lisa purred, still rubbing her victim's cock with the palm of her hand. "Don't you know that Sherry and I are good friends?" she smiled.

Randy coughed nervously and looked down at his lap, watching Lisa tugging down his tightly stretched zipper with a deftness of movement that amazed him.

"Am I as pretty as your little sister?" she asked insistently, smiling at him with that peculiar knowing smile that she shared with Sherry.

"Aw for Christ's sake, Lisa, I dunno. I guess. Why the fuck are you asking that?" he said as she reached inside his tight pants.

"Does that hun?" she said in a little-girl voice when he sat bolt upright suddenly.

"No… it doesn't hurt, damn it…" Randy gasped as he felt her fingers against the tightly stretched skin of his cock-shaft.

"You don't seem to be enjoying it," she said, pressing her long, warm leg against his.

"What's this shit about Sherry?" Randy said through gritted teeth.

"I'm just curious, darling, that's all. I. just wondered how I stack up compared to your sister. She is awfully pretty, you know. Have you ever seen her with her clothes off, Randy? She's very pretty with her clothes off."
