When I was about 10 years old, two neighborhood kids, my two brothers and I were playing truth or dare. Eventually, I don't remember who was dared to suck a cock first, but either my younger brother or I was dared to suck the other's cock. We both complied, to the jeers of the neighborhood kids. We both picked dare, and we did what we were told. No big deal, right?? Eventually, both of my brothers and I would have sex together. Mostly just oral. The one time my big brother and I tried anal, we made a pretty big mess... later on, I would wake my little brother up at night and I would ride his cock. We also crossdressed together... which was an interesting twist on what I've read about siblings experimenting sexually with each other. My older brother introduced me to our step-sisters satin string bikini panties. Ever since then, I've had a thing for panties.

Keep in mind, though, I don't think any of this had to do with my transition from male to female in and of itself. I knew I was a girl long before long before I had turned 10, even if I didn't have the words with which to describe it.

Now, I have a thing for sucking guys off while they wear panties. I think it's just the idea of a cock encased in pretty pink panties really turns me on.
