At the time, Fabiola and I weren't living together yet, and that evening, after picking her up from work and dropping her off, I headed home. I was always horny, but that evening it was stronger than usual, and it wasn't just a desire for pussy, but also for something else. I'd never paid for sex, but from friends' chatter, I'd heard about a beautiful trans girl with a dream ass, and I decided to give it a try. The idea of enjoying a beautiful ass and playing with her "big clit" turned me on like crazy, and I went to her, convinced that, given the fact that we were having a sexual relationship, she'd refrain from criticizing and mocking my small size and the speed with which I orgasmed. But things didn't work out that way. The beauty of her ass and the excitement of that new situation made me come even before I could fully insert my cock into her, and she looked at me with a smile. She took my hand and moved it to her big cock while she began to fondle my ass with hers, searching for my little hole. Once she found it, she penetrated it decisively with her finger. I had gone there that night to fuck her ass, but in the end, she penetrated me, and she did it decisively. It lasted a long time, and when she finally came, my asshole was on fire. When I got up to get dressed, she gave me a firm slap on the ass and told me that with a nice ass like mine, I didn't need to pay for cock, and that I could have as many men as I wanted to fuck me ass.
