Sherlock, demon detective, discovers a crippled ex-soldier with an unusual ability. John gives off a scent that is irresistible to demons; the more aroused and/or humiliated he is, the more irresistible he becomes. It doesn't matter how well a demon is hiding, once it smells John, it can't help but come after him.

Sherlock uses this to his advantage. Every time he needs to flush out a demon suspect, he snatches John from his flat and uses him as bait. John's horrified when he finds himself being fucked on a stage in a crowded club, or forced to kneel naked and suck Sherlock's cock for hours while strangers grope him. But there's no place he can go where he can hide from Sherlock, and Sherlock always makes him feel so good...
