My stepbrother massages me and I reveal my erection, catching him by surprise as he didn't know I was transgender

My stepbrother was massaging my back when I decided to surprise him with my cock. He was completely taken aback. He had no idea that I was a shemale. He was shocked and a little scared, but also very aroused. We continued to kiss and touch each other until we both came. It was an incredible experience for both of us.
