Sexual Assault on the Bus

I was 15 at the time and I was at the bus stop. A man walked past me, brushing my vagina. I ignored it thinking it was just an accident but when my bus came, I could see from the corner of my eye, he was copying my movements. When I went to the bus, he was coincidentally taking the bus. He was infront of me and just before going onto the bus, he turned around and groped my vagina, pinching it twice. My journey back home consisted of me crying. To this day, I regret not saying anything,
