I felt up my passed out brother in law
Why did you think it was okay to feel him up?
I think he was so hot and I want to give him a quick feel
You should have controlled your urges and stopped  yourself from doing  something so disgusting. You essentially sexually abused  someone since they were not consenting, and maybe even destroyed a marriage. I hope you come clean and get the punishment  you deserve, because you can't get away with something like this.
Do you know that sexual urges are uncontrollable sometimes. I just wanted to feel him and get it out of my system.
That's no excuse! You are being selfish when you say those things. You should confess what you did right away.
