His heart pounded with passion, but he hesitated. "Jesus, Sis, you're a cherry. It's bound to hurt." How he wanted to feel her pussy wrapped around his cock!

She pulled her knees back to her tits as his cockhead lodged between her cuntlips. "Push it in!" she whimpered, wrapping her arms around his neck.

He lurched forward, driving his prick into her virgin snatch and ripping her hymen. "We're fucking," he said.

"Is it in?" she said, relief flooding her. It didn't hurt a bit.

"Sure, it's in. Jesus, your cunt is tight."

Neither youngster had to be told what to do now. Their bodies took over and Billy began pumping his cock in and out of her swampy depths.

Penny was in heaven. With every thrust his cock seemed to rub against her clit. Her clit was sensitive from years of masturbating, but she'd never felt anything like this. Having a cock inside her was the most thrilling thing to ever happen to the teenager.

"Your cock is rubbing my clit," she breathed.

"Yeah, do you think you're gonna come?"

"If you can do it long enough I will. Oh, God, Billy, I love fucking! Don't you?"

"Yeah, it's great." He pushed in very deeply, causing his balls to slap her asscheeks.

"How many times have you done it?" she said, her teeth chattering with excitement.

"I don't remember."

"Oooooooooh, I feel so filled up with your cock."

"Jesus, your pussy's grabbing my cock."

The pulsating bar of male meat inside her stretched her insides deliciously. Everything felt wet and tight and wonderful. She had never oozed so much juice from her cunny. His cock, big as it was, streaked in and out with ease.

"We're really fucking," she said.

"You better not tell," he said.

"I won't. Oh, God, Billy, keep doing that!"

"I don't know how long I can keep it up."

"I just love it."
