"Anything for you."

"Good," Susan said. "Now roll over."

I rolled over on my belly and raised by ass in the air. I was nervous as hell. To be honest, I have fingered my ass a few times when I was beating off alone in the bathroom. I like to think that most guys have, but I could be wrong. But a cock is a lot different my finger.

"God that man's ass is chiseled," Susan said, slapping me hard on one cheek. Then I felt her tongue on my asshole, which was strange but pleasant. "You never dreamed about fucking Mike?"

"No."

She made a slightly disappointed sound, but before I had time to process it, the head off her cock pressed against my asshole. With a little more pressure it slid right in.

I have never had sex with a man, but I have fucked a few female assholes before. I don't know if Susan realized it, but most assholes don't accept a cock that easily. That most likely meant my best friend had done this before. A lot.

"Oh my god that feels so good," she moaned, and I could not disagree. As she pounded my ass I reached down and started stroking Mike's massive unit. "No wonder gay guys like this."

Being on the receiving end of anal sex is a mixture of pain and pleasure. Like so many other things I was experiencing, its hard to explain. As it slides in and out there is a moment where you want it to stop, followed my **** pleasure.

A moment later we both came.
