Mi (casi) primera vez con un chico (parte 1)

Hello to all, here's my story about the time I almost lost my virginity with a boy much older than me. I was 15 years old. Since I was 13, I like to steal my cousin's or mom's underwear and put them on, take sexy photos of my ass and send them to gay boys in groups or that kind of thing. The fact is that at some point I discovered Grindr, an application known by all gays (I suppose). I'm not gay because I also like girls. I consider myself bisexual, but in certain moments (when I'm gay) I can be very effeminate and love being treated like a girl more. I downloaded Grindr and used it occasionally. I would install it and uninstall it and so on. I liked exciting some boys and getting them to send me photos of their hard and straight penises, my mouth would water. One day I put on a purple thong that belonged to my mom and started talking to a boy. He offered to come over to his house. I was alone at home because my mom had gone out with her friend. I sent him a photo of his penis and he told me it was approximately 19 cm long. A small one. I got so excited and decided to go see him. When I arrived in a taxi at his house, he was waiting for me outside. He was slender, a bit taller than me. He had a gray short, clearly not wearing boxers because I could see how marked his penis was and how it stood out in that short. I greeted him with a kiss on the cheek and he put his hand on my waist very close to my left buttock. We went upstairs because he lived on the second floor. When we got there, he told me get comfortable. I replied that I wanted to charge my phone but didn't know where. He kindly pointed out a place to charge it that was right behind his TV. I went and bent down to connect my phone. Obviously, I bent down in a way that he could see my whole ass and notice that I was wearing this thong that He asked me to. Suddenly, as I was finishing up connecting my phone, I felt him grab my belt and push his penis against mine. I could feel it, it was actually happening. I felt so excited but wanted to be difficult. I turned around and told him what's going on? and he said I know you want to get slutty, then after saying that, he grabbed my ass and pulled me towards him to kiss me. He spread my legs and loaded me up, I could feel his entire erect penis in my ass as he loaded me up and kept kissing me. Do we go to your room? he asked. Without hesitation, I replied yes, and without letting me go, he took me to his bed. That's all for today, let them know if they like it and I'll write the second part of this story. Thanks🥰
