Train Ride with a Futa

You just barely manage to get onto the train heading for your school and also somehow manage to get a seat for yourself. Sometime into the ride you notice a girl standing in front of you looking all uneasy. She must've just gotten on from the last station. You then notice her uniform and recognize her as not only someone from your school, but someone from your class as well. You thought of striking a conversation with her when you notice her skirt mysteriously rising. And then you see the tip of her huge penis sticking out in front of you, dripping wet. What do you do? (Let's see how well this plays out... You can give the girl whatever name you want.)
