"Are you a virgin?" he said.

"Yes, are you?"

"Hell, no." He lowered his eyes to avoid hers. He was a virgin, but he didn't want to admit it.

"Are you really not a virgin?" the young girl said.

"Shit, I've done it plenty," he said. Actually all he'd ever done was touch a girl's tits and french kiss. Once a girl let him touch her, down there, but only for a minute.

"Jesus, what about Jimmy?" he said.

"He's been around too," the boy croaked.

The way she was touching his cock was driving him crazy.

"It's getting even bigger," she said.

He was beginning to forget that Penny was his sister. He covered her hand with his. "Touch it here," he said.

She touched the tip of her fingers to the rim under his cockhead. "Here?" she said.

His cock rose up in her hand. "Yeah, that's okay."

"God, it's getting hard," she said, one hand cupping his balls and the other caressing his prick.

"Well, what did you expect?" he said. He was finding it difficult to breathe. Somewhere in his mind he knew he ought to stop her, but he was helpless. Her hands on his cock and balls felt too good.

"I watch you sometimes," she said, lightly stroking his prick.

"Yeah, when?"

"When you're getting out of the shower, like today, and sometimes when you're in your room."

"Well, I watch you sometimes too."

"Honest?" she grinned. "Did you ever see my pussy?"

"Yeah, once," he said.

"Did you notice all the hair I've got now?" His cock jerked in her hand. "Yeah, I noticed."

She pumped his prick until the skin pulled tautly over his hard-on. She breathed rapidly and felt the oozing moisture between her legs.
