I used to go over to my step cousin's house when I was 7 to 10 years old since my dad was a cousin to her step dad. I specifically remember one day when I was around 9 years old my step cousin who is a year younger than me asked me if I wanted to play house with her. I said yes of course since I thought we were just going to play house like kids tend to. But then she said that she'll be the mom and I would be the dad. And I just remember her kissing me as she would pretend we were getting married. Afterwards she told me to touch her private area since that was what she saw her mom and step dad doing. I never told anyone that this happened to me since I feel a lot of guilt about it. Since my step cousin was a year younger than me at the time and I never really thought that it was weird at the time. But as I got older I realized that it wasn't normal for two kids to be doing that. I haven't told anyone that this happened to me since I feel a lot of shame and guilt for it. I still feel like it was my fault for letting it happen now I can barely live with myself because of how much shame I feel.
