See what he does

There is a brief pause when Zack realizes his dick is in your ass and not Katy Perry's, but then he he keeps going.

"Fuck, dude, that was dirty," he says as he pounds in and out of your ass. "Damn, you never told me your ass was so tight."

"You...never...asked," you say between moans.

"I'm still not gay, but damn," he says as he leans forward and and spits a little lube into your ass crack. "I can't say we won't have to try this again."

It isn't the confession of love you would have liked, but it was close enough. Part of you had feared he would realize what you had done and beat the shit out of you. Instead he was giving you the best ass fucking of your life and he was enjoying it.

You've fantasized about having sex with guys, but this was definitely better.

Zack might not know anything about fucking a guy, but he knew how to fuck. But, you suppose, an ass is an ass.

"I'm gonna cum," he warned.

"Me too," you moan as your cock explodes all over Zack's bed. If was a first. You'd never cum just from having your prostate stimulated before.

Zack grunts and then thrusts harder. You feel the warmth spreading inside you and sigh. He pulls out and takes a step back, looking at you bent over the bed, his semen leaking out of your ass.

"Look...I...uh...I am not sure what that means," he says, his sex field confidence gone. "I...I have never even looked at another guy before... Maybe...shit... dude..."

You need to do something quick, but maybe more mind games isn't the best way to handle it. Zack was a macho horndog, secure in his own straightness until just a few moments ago. It never would have happened if you hadn't fucked with his head, and now he's fucked up in the head. You know people will do some crazy stuff in the heat of passion, but it's how they handle it that matters.
