"Sure, it's still hard. And you can't see it."

"Why?" Her voice was excited. "Cause the light's on? You used to show it to me."

"Yeah, but we were just kids then."

"Don't be silly," she said. "Let me see it."

"Why, do you want to play with it?" he grinned.

"Well, why not?" she giggled.

Mark's prick shot up under the covers. "Do you mean it? Jesus, if you mean it I'll show it to you."

"Go on then. You show me your prick and I'll show you my pussy." She preened seductively. "It's changed a lot since you saw it. It's all… oh, you know, I'm a woman now."

The boy's cock swung up to hug his belly. "You mean it?" he said. "You'll show me your cunt and play with my cock?"

"Sure," the redhead grinned. "We're both old enough to lose our cherries. You still have yours, don't you?"

"Yeah."

The boy threw the covers back and revealed his prick. Betsy's eyes popped when she saw her cousin's cock. In the years since their mothers had bathed them together his cock had grown huge. She stifled a giggled with her hand.

"It's so big," she said.

"Are you gonna touch it now?" he said proudly.

"Wow, you've got a hard-on." Her eyes glistened as she stared at the boy's cockpole.

He wrapped his fingers around, his shaft and waited. "I'll get even bigger if you pump it."

"Jesus!" Extending her hand, she placed it on his prick.

"That feels nice," he said.

Mark's experience with girls was limited. His cousin's hand felt terrific on his cock. He wondered if she'd jerk him off.

"Wow," Betsy repeated again and again as she moved her fingers back and forth over the velvety skin of his prick.

"Feel my nuts too," he said.

With a pounding heart the teenaged girl cupped his balls and felt the hardness within.
