I was a young boy at this time who still used the toilet up to this point. There was this girl about 6 sat next to me on the bus bench wearing a skirt, shirt and socks and shoes. She was blond with pigtails. Instantly I could smell poop and noticed it was coming from her. Her mum came over and asked if I could check her daughter's nappy. Embarrassed, I lifted her skirt and peeled back her nappy. Stench of girl poop wafted out. I even got her brown mess on my hand. The mother explained her daughter was being punished and had to wear a messy nappy in public and show it to strangers. That's when she reached down and pulled the girls skirt off. Wearing only a messy nappy, her and the girl walked off with others watching them. She left the skirt and fresh nappy on the bench next to me and said I could have them. My mum came by and asked what happened. Mum smiled and said that I should wear them. I told her no but she insisted. She said that I already looked like a girl and it was convenient for me to wear nappies. She really wanted me to wear them and she was ready to argue. So, I finally obliged. I laid down on the bench. Mum pulled by trousers off. Then, the nappy and skirt was put on me. Mum took a picture of me and showed me. I looked just like a girl and it was very surprising.
