You know, this is the kind of thing so far from what I'd normally be interested in that I'm not sure I'd ever even read a rentboy fic before -- until I got pointed at one last week that was actually not bad. In that it took advantage of a canonical abuse situation with access to high tech of the indistinguishable-from-magic variety and suggested a variation where the evil character had mindwiped the other one and dumped him somewhere with three pills in his pocket of a drug that was severely addictive for their species. Let him hang out for a few months being a junkie whore. It worked but I can see how rarely it would work as a fic setup.
