Dirty Kahn
A young dude who ends up going home from the pub with an older couple, and services the lady while the old man spectates from the sidelines.
Kahn was stoked to have scored that night, but he was a little put-off by the movements coming from the dark corner of the room where the man was sitting. Nevertheless, he went about his business and got the job done, thus creating the grotty story of The Dirty Kahn.
