I work in Washington DC which has an immaculate subway system. I have about a 40-minute commute into town and 40 minutes back out every day. The trains are always stuffed for the last 30 minutes or so into town and first 30 minutes coming back out. I had been riding the subway for about three months when warm weather came and women started wearing skirts on the subway. I would usually move to the back since I was riding almost the entire distance the subway travels.
One day I noticed a girl in a light cotton short skirt standing beside the seats with one hand holding a pole and one hand on the back of a seat. Everyone was packed in very tight. A guy was in the seat right next to her. Right after the subway started moving I noticed the man took the back of his hand and rubbed the outside of her leg. I thought it was an accident at first, but then his hand moved to the back of her leg and rubbed lightly again. I expected the young women to brush his hand away or move, but she did not move. The man then moved his hand to the inside of her legs just above her knees and rubbed his hand slowly up and down touching the inside of both legs. It was so erotic to see a man touching the women in open sight on the subway. I looked around and the way everybody is packed in nobody even noticed except me. The man slowly caressed the inside of her legs up and down. His hand moved gradually upward until it disappeared underneath her skirt. He moved up until he had to have been touching her panties. The young women moved which startled me because I was watching with so much erotic energy.
I thought she was going to move away, but instead she moved her right leg back and apart a little more. He kept his hand under her skirt for the next four or five minutes or so until she suddenly pulled her legs together. He slid his hand out and a minute later she got off at the next stop. That whole scenario was so erotic and unbelievable. After that time, I started looking carefully and noticed that a number of women with light cotton skirts would position themselves by the seats with men in them. I also noticed that sometimes a girl would wait a couple of stops and then move to a different seat with a man sitting in them. Over the next month I saw over a dozen girls get felt up that same way. I could not believe that girls were actually letting guys touch them on the subway. It seemed as though it was almost a game to pass the long commute. I also noticed that when a guy touched a girl's leg on the out side and she did not want to be touched she would immediately move. If a guy rubbed the side of her leg and then moved to the back of her leg, she would always let them run their hand up underneath their skirt. Over that month I never saw a girl get upset or make a big scene. If they did not want touched, they would move quickly after the first "accidental" touch by the man in the seat.
