He fucks her

Christy got on her hands and knees, and began to shake her ass at the nerd, mesmerizing him.

"You stare at my ass a lot," she teased. "Do you want it?"

Rob nodded. "Y-yes."

"Take me, then," she moaned.

Your friend didn't need any more persuasion. Rob got behind her and slowly stuck his cock inside her. He held her waist and pumped in and out of her. It was his ultimate fantasy to be inside your girlfriend, did it turn you on knowing this guy was thinking about Christy?

"Shouldn't I be wearing a condom?" he asked.

"No! I want you to fuck me anyway..." if that told you anything, it was that Christy was going to take this all the way.

Rob took it a step further and spanked her ass, making her moan. His cock stretched her and you could hear his excitement as her pussy took him.

Christy was moaning rubbing herself dowm as her fucked her. If she still wanted you, she might think of him instead.

"Am I better than John?" he asked, quickening his pace and forcing your girlfriend's face into the floor. He took out years of angst on Christy, pounding her the way he had always dreamt.

"You're so much better! Please, claim me, Rob!" She begged, pressing him into her with her legs.

He started to groan in pleasure and you knew what was coming. Your girlfriend's pussy was going to be filled by this virgin and there was nothing you could do.

The sound of balls slapping ceased when Rob plunged his cock inside Christy with one final thrust, spurting ropes of his cum inside her. He finally got what he had wanted since he met her.

Christy shook rolled her eyes back, feeling the shock of taking another guy's cum. They both parted, leaving some of his seed to spill out.

"That was awesome!" Rob announced. "Can we do it again sometime?"

Your girlfriend sat up and kissed her new lover on the lips.

"Of course," she replied. "It'll be our little secret."
