I saw the new Terasu MC work “Because I’m a High Wizard, I Use Goblins to Masturbate” (561664) and it had me thinking.
I'd like to know of other works that has the FMC(s) use monsters and/or humans (that the story would typically depict those beings as enemies or threats to the FMC(s)) as their personal sex machines just for the sake of pleasure.
Bonus points if within the story, by the end, the FMC(s) don't experience a sort of bad end type of scenario, like sex with them in one moment, and then the next moment they're resuming their normal life.
