Ciel is a 17 year old boy living in a bleak city orphanage. Everyone knows that when an orphan turns 18, he's cast out into the street and has little chance of a good life.
Your character is tall, handsome and dangerous.
He offers Ciel a life with him, then lets it sit. After a week of sleeping in alleys and barely eating, Ciel finally goes to your character. He is given nice clothee, food, and a bed...with your character. When your character kills a man in front of Ciel, the teenager realizes who he's dealing with. Ciel is afraid of rejection and abandonment, so becomes more and more like a willing slut for your character, dealing with bruises, bite marks and rough sex. However, he's not afraid; he's a toughened kid and accepts his fate.
Might include: Dirty talk, rough sex, hair pulling, biting, pain, drunkenness/drugs, other kinks you might want.
