I'm a 21 year old male. My parents died when I was 8 years old and I was sent to live with my 2 older sisters who were 20 and 22 years old. Until I was 13 they behaved very weirdly with me. They would slap, grab or make comments about my ass whenever I walked past. They would pretend to spank me. One of them would put me over their knees and pull down my pants and underwear and spend at least half an hour caressing my butt. Also they would spy on me everything I had a shower.

It kind of messed me up a bit. I didn't trust anyone for a long time and was really depressed. I never told anyone as I didn't think they would believe me.

I just want to know why they did this and was it abuse?
