About a week ago my daughter (4) told me our roomates son (8) " pulled down his pants and underwear and her pants and underwear and put his pee pee on her pee pee" I asked for more information and was told she told him to stop and that it hurt. I asked her when it happened and she told me "one day when you went to work"

The kid admitted to putting his penis on her vagina but with clothes on. My daughter is only four and has not been exposed to this stuff. If she was right about some off it then she was right about the rest.

However, I don't know what to do. I'm heart broken and scared. I was sexually abused in my teens and it scarred me and effected my life so horribly.

What do I do?
