My beginning as a transvestite and slave

I'm a 18-year-old transvestite girl, and I'm going to tell you how I became a transvestite. It didn't happen overnight. One day, I was walking through the city center when I saw an erotic store, or sex shop, and I felt the urge to go in. Logically, I was embarrassed that people might see me, and my heart was racing, but I gathered my courage and went in anyway. There were shelves of erotic toys, condoms, and all that stuff. I was nervous as I looked at the toy penises, but I was just another customer, and no one was paying special attention to me. In one part of the store, I saw that they had pornographic movies, and I went to check them out. There were beautiful women with men, beautiful women with women, wow, everything. And further on, there were gorgeous guys with gorgeous guys. What a thrill, but I picked up a box to take a look. I was really nervous at that moment. A staff member approached me, and I didn't even notice him coming, and he told me that they had a cabin service, in case I wanted to use it. I turned to look at him in surprise, and if I had seen him coming, I might have run out of the store. But I didn't understand what he meant by "cabinas."

-How does it work?
-You choose the movie you want, and you watch it in a cabin.
-Any movie?
-Yes.
He told me the price, and it seemed reasonable. Since the movie I had in my hand had caught my attention, I said I wanted that one.
-Okay, this way, please.
He pointed to the counter where I would be attended to. I went and waited for the man who was attending to arrive. There were hardly any people in the store, which is why I felt brave enough to go in, but I was still nervous. Then, another guy came in, tall, handsome, with white skin and another movie in his hand. At that moment, I didn't want to look at him. The man who was attending to us arrived, greeted us, and asked for my movie. He opened the box, took out the disc, and put the box on the counter. He asked the other man for his box, took out the disc, and put the box on the counter next to mine.
-Let me just check something.
The guy stepped away for a minute or two, which felt like an eternity to me. I felt uncomfortable and wanted to leave. I saw that the man was looking at the box of my movie, and I felt embarrassed. But I was also curious about what movie he had chosen. It was a movie about transsexuals. Wow, what a beautiful girl, so feminine, with a beautiful penis, just like the ones in my movie.
-Hello, he said.
-Hello, I replied, not knowing what else to say.
He extended his hand, and I shook it.
The staff member returned and referred to me:
-Do you want an open or closed cabin?
Oh my god, what was that? Why had I come into the store? The guy saw my confused expression.
-In the closed cabin, you only watch the movie. In the open cabin, there's a hole in the wall so you can see the person next to you or interact with them through the hole.
I was so nervo...
