My first squirting orgasm

I introduce myself, my name is Susana and I'm a 21-year-old 100% Salvadoran sissy. Very well, I'll tell you how it was the first time I had an orgasm with my butt, it was about two months ago, not long ago 🤭. It turns out that I had bought some small, medium, and large plugs by mail and was very excited because they would arrive when the day finally arrived, so I went to pick them up and as soon as I got home, I took them out of the package and saw that the largest one had about 5cm thickness (obviously it wouldn't fit in my butt) so since I was excited, I took the smallest one, did an enema, and inserted it. As it was the first time I had a plug in my butt, it felt a bit strange but I played for a while putting it in and taking it out until my butt got used to it. When I finally could tolerate the small plug easily, I took it out and took the medium one and obviously it hurt a little when I was putting it in but it was easier than before and kept dilating more, when suddenly I heard my parents arriving and scared, I took everything and hid quickly but left the plug inside my butt. This was around 6 pm so I stayed with the plug but was very scared and felt very uncomfortable so I went to bed and then played a little with the plug while waiting for everyone to fall asleep. When finally everything was silent, I took off my pajamas and put on a thread and a baby doll that I had bought days ago, so I got into bed and kept playing, since I had had the plug in my butt for a few hours, I took it out and grabbed the largest one. Since the size difference was quite considerable, it hurt a lot when I tried to put it in, so I took a lot of saliva and put it on the plug and my butt and slowly slid it inside, when finally it went in, there was a mix of pain and pleasure because the plug was squeezing the walls of my butt and it felt wonderful 🤤. So I slowly started taking it out and putting it back in and felt like my anus was dilating, the plug I'll come in with great ease and only feel pleasure now, so I've been like this for about 40 minutes until I started feeling something weird in my little penis and knew I was about to cum, so I started putting and taking the plug in and out much faster and constantly when I felt my whole body shudder and I started running a lot, it felt like a mix of my semen with urine, kept putting and taking the plug in and out and each time I put it in, it cost me to control my body, it was a wonderful sensation and I had almost a blank mind, the only thing I thought about was that I was cumming with my ass and didn't want to stop feeling it, finally I left very tired and bathing in my own semen.
