"Promise it won't hurt."

"I promise."

"Okay, then I want to do it."

"Dynamite!"

He quickly tugged off his tee shirt and pulled down his pants and briefs, then slipped off his sneakers. As he helped the young girl off with her dress he saw she couldn't keep her eyes from his jutting hard-on.

"God it looks enormous… are you sure it's going to fit?"

"Hold it… don't worry, I'll make it fit! Just hold it. That's it. Stroke it… shit, yeah!"

She felt its rubbery smoothness.

"Cup my balls. Feel how heavy with cum they are."

"Mark, I've never heard you talk like this before."

"There's a first time for everything, Susan." He gently pressed her back onto the couch and lay beside her, their naked bodies sinking luxuriously into the plush cushions.

His lips pressed against hers. They were hot and anxious. One hand went under her tit as his tongue slipped between her quivering lips. They French kissed, the girl's tongue soon returning the boy's lustful darts and caresses.

She gripped his buttocks and squeezed, feeling her blood boiling. He spread her legs and pressed two fingers into her young cunt. They came out wet with her fragrant juices. She moaned blissfully and pressed closer to him. He finger-fucked her hard, reaming directly underneath her swollen cunt until her breath came in quick pants of pleasure.

"Ohhh, Mark, you were right. Yes, yes, I can feel it now. Slowly building… like a wave inside me… mmmm…"

She started jerking him off, fisting him tightly.

It was all happening so quickly. Susan couldn't comprehend it all. She was lying naked beside her handsome young cousin – young, but older by two years than herself – ready to guide his hardness between her thighs…

"I want to fuck you now," he gasped, feeling his balls tightening.
