My older sister had a similar situation only it was when she helped as a teaching assistant in my school during the embarrassing drama class which resulted in her huge ass getting grabbed by the horny boys, we were all 17 at the time and she 27

I had something similar, my mom was played with a bit by my friends, it's the only experience like that to be honest, I could definitely see hands on her buttocks at some points and I could see hands resting on her tits, the left breast in particular was even exposed, I could see my friend trying to run his hands over her nipple as much as possible
