I remember this one being translated but I can't remember the author, the manga or the one-shot title. A high school boy winds up on the all-women car in a train. The women suddenly start going after him. I recall the first was a bit younger than him, and when her stop came up complained that she wanted to continue to "bask in the afterglow" or something like that. He ended up going from girl to girl before the girl he had a crush on showed up and did it with him. I'm not sure if I'm confusing this with another story with a similar concept but I think the gig was that girls who have crushes can have their crush pushed onto the train.
