Riding

Kate pushed me back on the couch and then straddled me. My cock slid easily into her pussy, which was not as tight now as Amy's. I gripped her by the hips as she rode me.

"You feel good," she said.

"So do you."

It was moments like this that I did still feel a little guilt about cheating on her. I guess its only fair to admit that people have no control over their sex drive. Just as I couldn't help being horny all the time, Kate couldn't help being largely uninterested in sex.

"Are you almost there?" she asked.

"Not yet."

I told myself, at least I was cheating with someone who had no real interest in me, other than my cock. I could have been out running around with a home wrecker looking for a husband. Like me, Amy just wanted to fuck.

"I don't think I can take much more," she said.
