When my cousin (female) and I(male) were little, we were exploring each other. We were about four or five, and wanted to play a game in a blanket fort. Our parents had left us for the day, and both of us had been exposed to the hub before. We both watched porn for hours and then we wanted to try it. So she and I both got naked and we tried to gross out the other person in the tent and get them to leave. It started with kissing. Then it progressed to at one point I stuck my finger in her pussy. Then she licked my dick. I got bricked up and didn't know why. So I put my balls on her cheek. And then she sat on my face. Eventually she just sat on my dick and my dick didn't go into her. We did that for like 30 minutes until it did, and she said it hurt, and left. She didn't tell anyone and I haven't either. I moved a few days ago and she wanted to do it again before we left. We didn’t. Because now I understand how wrong that is. I’m trying to forget what happened but I’m not sure how to. Any suggestions?
