Sometimes...

My roommate is gay

We were just friends until we took shrooms together once. We ended up fucking each other's brains out.

Since then, sometimes, he and I fuck each other.

We have never talked about it. Not once. I'll just walk into his room with a hard dick or he will walk into mine. It's like ever since we took shrooms together, something primal unlocked inside us together.
I'm straight. I love fucking women. I'd never fuck another man.
But sometimes I just need to ram my dick in my gay roommates ass and breed him like the slut he is until he is screaming in ecstasy as I empty my balls into his tight, gay little ass while my eyes role into the back of my head and he's filled to the brim with my baby juice.
