Go by tube

There is a tube station just around the corner from your house so you head there. You and Lucy buy a ticket from the machine and make your way up the stairs to the platform. You can feel a cool draft blow up your skirt as you wait for the tube to arrive. It causes a tingling sensation between your legs.

After a few minutes the tube train pulls in and you and Lucy get on. The carriage is fairly empty at this time of night. There are only a few people on board. The compartment is arranged in several sections, each with rows of seats facing each other. When passengers are seated, each section is virtually private from another.

You look around and see a teenage boy sitting by himself in the section at the far left end of the train. There is a woman in her twenties sitting in the section to your right. Near the door where you entered are a young couple seated together.

"Where shall we sit?" asks Lucy.
