The Backdoor

"Have fun," she said with a wink.

I walked to a vacant stall and closed the door behind me. I didn't really know what to do next, so I sat on the closed toilet seat and waited. I was in between two other stalls already in use. I could hear two people moaning to my right and the harsh slapping sound of bodies colliding on my left. I wondered if the girl at the door was actually a tranny. If she was, I couldn't tell at all. I don't think anyone would ever guess she was either. If all of the t-girls in this place looked like her, then I definitely came to the right place. I started imagining what the girl at the door looked like naked. I couldn't help picturing myself stripping her clothes off of her smooth curves and kissing my way down her body towards her hard girl-cock.

My fantasizing was quickly interrupted by a cry from the stall to my left.

"Oww!" I heard a man yelp. "Oh, God."

"Yeah, you like that, don't you, bitch?" This voice was clearly masculine but trying to make itself sound feminine. The slapping sound coming from the stall next to me grew louder as they started fucking harder and harder. I looked under the partition but could only see their legs. There was a skinny set of white legs facing the direction of the toilet. Right behind those, was a set of very muscular black legs which apparently belonged to the big tranny who was fucking the shit out of the skinny guy.

"Yeah, you take that big dick," said the tranny.

"Unngh. Yes, Mistress Natas- OH! Yes, Mistress Natassia." The sound of them fucking was incredibly loud. I watched under the partition as the huge black tranny rammed the poor skinny guy who kept trying to keep his balance.

This was not what I thought I signed up for. That tranny was practically just a guy. I was extremely freaked out. Maybe I hadn't thought this all the way through. What if I got someone just like that? What if it turned out to be just some guy in a wig? I was just about to stand up and chicken out, when there was a gentle knock on my stall door.
