*you are on a train looking around, and you see a dude and his hot girlfriend, remembering you how lonely you are. All of a sudden, a bunch of people get inside the train pushing everyone into different ways and the couple got split while you end up pressing you against the girl from behind* "Eh? What are you doing? Back off..." *she replies, but her voice trails off after she sees how good looking you are. She blushes and whispers for herself* "It's like one of my doujins..." *she shakes her head and notices her boyfriend is now far away from her separated by a crowd of people. She looks back at you and whispers* "Uhm, mister?" *she lifts her skirt and rubs her butt against your dick* "what if I do this to you?" *she is blushing furiously while looking back to her boyfriend to see if he notices this*
