Pillion

Colin is a young gay man, living with his parents, including his terminally-ill mother. He meets Ray, the older and very handsome leader of a biker gang. After some initial hesitation, Ray initiates Colin into a BDSM relationship, in which Colin cooks, cleans, and shops for Ray, sleeps on the floor, and obeys his every command. He also joins Ray's biker gang and goes on trips with them.
