Jumped on the tube, sat next to someone watching their iPad with huge headphones on.
After we moved, I had a quick peek at what she was watching. It was a blonde lady performing a sexual act on a man, presumably the person who had filmed this.
Peered up at the woman then realised it was her who was starring in the "home movie".
Person other side of the iPad user gave a big smirk and little giggle.
Completely surreal experience that has left me questioning why. It was the morning rush hour, for goodness sake.
