My sister and I are close. She is a year and a half older than me. When we were home alone, we liked to cuddle and watch movies together. We didn't have a lot of friends because we lived in the country. She and I shared secrets and we could trust each other not to tell. She told me she wanted to be a guy and said that being a girl didn't fit right with her. This was before being trans was acceptable and girls like her were just tomboys. I said ok then be a boy nobody will care. She laughed and asked if she could try on some of my clothes to see if they fit and she liked the way my jeans fit better than hers. She told me that guy's clothes fit better and liked the way they smelled like me. I had no idea that she had a crush on me it was playful and innocent at first. She would change clothes right in front of me and I would try to look the other way. She would kiss me and tickle me and get me to kiss her. But as it went on we started to become closer. She would borrow and wear my clothes and T-shirts to wear to school because she liked hanging out with me and my friends. She would try to tease me and even kiss me in front of my friends. Eventually, we started sleeping together and she even wore my underwear. I wore hers only because she wanted me to. We remain close and we love each other more than most brothers and sisters do.
