When i was about 6 years old my mom used to go to a psychologist who had his office in his house. While she had her sessions I would play with his 5 year old daughter in her room. Pretty much from the first day she took control and decided we would play rock star, which basically meant she was the rock star giving a concert on top of her bed, and i would be on the floor watching her. After the "concert" I would go backstage to meet her and then we would start kissing and doing other stuff.

We played the same game every time i was there. I dont remember how many times i went there, or how fast everything happened, but I do remember being completely naked with her under the covers, full on kissing and touching each other. Now that im older i'm thinking she knew way too much about sex for a 5 year old, and she must have been abused or something. I never told anyone until now.
