I groped his sister once when she was alone at his house
When I was going to pick up the drill that my former bully (who's now my friend) borrowed, I saw his sister was alone when I got to his house and I asked her to assist me finding the thing. While she was looking for it, I gropped her tits and she resisted it. I even led her to bathroom but she won't go with me inside for some reason. Then she ran outside out of fear. I left the place immediately after that and I had the most stressful fap I ever had when I got home. I felt like roping at that moment because I thought that her parents are going to come after me and send me to prison. I couldn't even sleep at night. I didn't go outside my bedroom for almost three days due to fear that my parents would tell me about what I did, they kept banging my bedroom door and everytime that happened, I lose my shit because I thought that this is it, but eventually I went out of my bedroom due to hunger and needing to pee, and I found out that my parents actually kept banging the door because they're wanting to tell me about some stuff in school, and knowing that was a relief because I thought my life was over.
I also groped his sister's big tits and ass once at a birthday party
When she was washing the dishes, I grabbed her ass and felt it from behind. When she was sitting while looking at her phone and there was a box of toys on her lap, I picked up a toy from the box then pressed her right boob (with the hand I used to pick up the toy). Then I immediately went to the bathroom to fap (quite disappointing climax).
But I suspect that her brother saw me groping her because my parents said he was looking for me when I was at the bathroom.
Also, I noticed that their parents unfriended me on facebook. I think they know
