A mini-movie on a girl that rides the subway one day.
A teenage black girl takes the subway one day, it pulls off and gets very bumpy as soon as the train hits the tunnel, she then tries to ignore it and continue on her thoughts. The train persists with its bumpy feeling and vibration as it goes around curves and junctions. About 60 seconds into the ride she starts to get horny, 30 seconds she is very horny and is giggling in tandem with the trains rhythm as it turns. She finally orgasms from the vibrations & squeals. I explain how the process works and how she got horny in the first place. NO MATURE CONTENT
