Looking for a john who becomes infatuated with the male prostitute he hires -- and keeps hiring, eventually setting up an exclusive contract. Definitely smut and plot, complications with the prostitute (maybe immigration issues, maybe health issues, maybe a pimp who wants a cut and will do whatever it takes to get it), complications with the john worrying about a scandal if his contract comes out, but he can't let go of this guy. Maybe it's love. Maybe it's just obsession. But either way, the john just cannot get enough and will do anything to hold on to this prostitute, and doesn't want anyone else to have him, either.
Kinky is good. PBs, no celeb. Definitely slash. Modern or historical or fantasy. Looking for the john.
