Lately, I've been thinking of a story idea that seems very underrepresented.
It would be cool to have a story that revolves mainly around the slow corruption of the male MC. Corruption is an extremely common fetish, but it's almost always applied to the females. It could be MC corrupting them, some NTR dude corrupting them, or female MCs corrupting themselves. We rarely see fully fleshed out slow corruption of the male MC. I see so much potential for this in the mind control genre, but I still have not found one that really focuses on the MC's moral degeneration. MC just happily mind controls everyone, or has no self awareness at all the whole time.
I can think of a few scenarios. First one is a superhero universe where the MC is a super idealistic young adult that looks up to the heroes. He especially looks up to the "League" and the top dog flying brick of this universe. He finally applies and gets into the training program or whatever. Mind powers seem standard for the story. The powers should start out very weak. Something like limited telepathy. The MC spends his days doing hero stuff, but he slowly finds that the face of the heroes he idealized were just a front for the public. Think along the lines of The Boys. Perhaps they are not so overtly fucked up as The Boys, but hypocrites and self absorbed assholes. So there is some disillutionment, but the MC is still hopeful. There are also some heroes that are legit and kind. He wants to change the hero association for the better. Due to his telepathy, he gets to know their inner demons and hypocrisy. He learns how vile the top heroes are. His powers grow in scope and strength gradually and we see him use it on other heroes. He uses it for good at first. Resolving inter hero disputes. Manipulating the mega bitch into being kinder. That sort of thing. At some point, maybe he misjudges the effects and things get out of hand. Maybe the mega bitch becomes obsessed with him. There could be a series of events that kind of spiral out of control from this. Mega bitch's hero boyfriend gets angry. You try to quell it. Etc. MC gets increasingly jaded and slowly start to abuse his growing powers. Of course, there would be push back from the top heroes once they understand what's happening. The maneuvering and battle against the top heroes would be the final nail in the MC's psyche. In the end, he becomes an omega level super villain that enslaved all the heroes, including the ones that were actually kind to him (of course, most of the major heroes are females. Males could be cuck fodder or killed off to show MC's descent into corruption).
The second scenario would be a more contemporary setting. MC starts as a goody goody average kid with the usual relationships. Strict mom, bitchy sis, sweet sis, caring gf, bitchy boss, whatever lol all the tropes. He gets mind control from whatever source. It starts weak but will grow throughout. Using this more and more has a corrupting influence on the user (something that is made clear to the MC). He resists using it at first. There could be some incident where he is forced to use it to resolve the issue. Maybe his family becomes a target of the mafia or something. This sets off a chain of events that leads to more and more use of the powers to cover his tracks and deal with increasing threats. He is using the powers to protect his family at first, but the continued use is corrupting his mind. He doesn't resist the allure of using the power to ease his life as much at some point. He starts developing incest thoughts for the first time. Eventually, he starts abusing the powers for sexual pleasure. The main theme is basically the irony of the MC having to use his powers to help his family, but ending up as the biggest monster who mind breaks his whole family and others.
