So a few years back I was riding the Metro in DC . It was morning rush and the subway was pretty packed , standing room only . I was up with my back against the door and this cute little twenty something comes over and stand against the partition to my left and she was just in front of me . As the train is moving a bucking she proceeds to settle her little butt right up tight into my standing lap . I mean she us up close and real personal . She was like this til I got off at my stop . At times from the trains movements she was kinda grinding into it . So what's acceptable . Can I grab some I mean hell she started it . Do I say thanks . Should I have tipped her . I think about it every now and then wondering was I just a seat or a thrill .
