I hesitate, David makes a move

I sat there petrified, not sure what to do. I wasn't gay. I wasn't into guys at all. I wanted to run away. Yet David knew what he was doing. He'd managed to get me rock hard again by doing very little.

"Shhhh," he whispered. "Let me take care of this for you."

He raised his hips and slid his body up a few inches. When he lowered his hips back down, my cock slid right up the crack of his ass.

"Have you been with many girls?" he asked, leaning his face close to my own.

"A few."

"I've been told this is better."

David moved his hips again, managing to line my cock up perfectly with his asshole. Then he impaled himself on me. I wanted to protest. I wanted to say how disgusted I was...but it felt good. His ass was tight and warm.

"Like that don't you?" he asked as he rode me. "Don't worry, you were tricked. This doesn't make you gay...unless you are. Most guys are just looking for a nice, tight hole to cum in."

David leaned down to kiss me again, and as he did my cock exploded in his ass. He kept riding me until I was spent.

"Happy birthday," he said as he climbed off of me.
