Is it considered malestation
Okay a long time ago(around two years ago) my family made friends with this other family, they were around the same age as us, my sister even started dating their son. The father who's name is Rick hit on my mother and tried to get her to have sex with him, my mom refused to be around him alone now. Then around a year ago he kissed my sisters neck and hit on HER, (she was around 16, he was around 60) and then just last week we were going to watch a movie, and we went in my fathers car(which is an el Camino) so there was only three seats, I sat in the middle and when he was trying to buckle up I felt him grab my butt, strait up and it didn't feel like an accident. I screamed and jumped up and he apologized and my dad wouldn't hear that he had done that, is this considered malestation or is it just frowned upon?
