A super type school girl who happened to meet on a crowded train. Her crotch, which was erected due to her too close contact, was pressed steadily around her, and was in close contact with her crotch. She is also in estrus due to the pseudo-sexual intercourse between her crotches rubbing against each other with the shaking of the train, and it develops into her real intercourse as it is. I can't believe an erection makes a woman come into heat like this!
