I appear to be on a train, but sitting in a booth like in a restaurant. I and another guy are sitting facing the window, and two girls are sitting across from us, with their backs to the window. One of the girls is prettier, and the other is younger. I think I'm dating the prettier one, or I want to.

The two girls start kissing each other. The prettier one seems to have some lesbian experience, and to the other, it seems new and adventurous. The other guy is kind of awkwardly enjoying the show. I wonder if I should tell him that I slept with both of the girls already; for some reason it seems like pertinent information.
