This happened recently. I was heading back from the gym. Working out always makes me horny and I struggle to hide my self sometimes. It was a packed train and this women was standing close to me. I turned my back to her when she got on so my dick wouldnt accidently rub up against her and offend her but to my (pleasant) suprise she reached around and grabbed me. Honestly I was in shock and just toldy self that she didn't mean to but as she carried on squeezing I pushed back against her. She giggled and said something like "aw you're cute" and then let go and went back to her phone. She stayed on the train from another couple of stops and left. I really hope I see her again but don't k own whether I shoud approach her. Or whether this was just a fantasy she fulfilled and wanted to keep it that way.
