Green Line molestation

I had a disturbing trip on the green line the other night. I was coming back from school. As usual I climbed aboard a jam packed train and had to squeeze in front of some people to grab a pole. As I grab a pole I noticed that this guy slid right in behind me and grabbed the same pole. Let me tell you there was no where AT ALL for me to move and I think he knew that. SO he immediately pushes his crotch against my butt. Which has happened to me before...do they think I am just there for their pleasure??? This is when it gets worst though. I KNOW he actually pulled out his penis because I could feel the thing poking and literally throbbing as he was grinding up on me. The whole time his face was like 1 inch from me. I really felt scared. BUT yes this guy really did it. A hand started rubbing my crotch too like really rubbing it.. I was too scared to even look back and it could have been someone else too. it was SOOO tight I couldn’t go anywhere. Anyway he kept going then all the sudden pushed really hard and stopped. Just then he got off the train quickly and I never even really got a chance to see his face. However he did leave a disgusting wad of something on my jeans. I don’t know if it was spit or I HOPE not what I think it was. I am actually taking the bus for a while…. I was totally degraded and I would have taken a pic but I was like petrified and just tried to shrivel up and go away. I wish that creep's piece would fall off. Krista, Brookline
