Ok so the academy is a city-wide sex dungeon with the mayor as the Mistress and the headmaster as the de facto Master. Everyone is in on it, even MC even though he has forgotten because of the trauma of seeing his gf/wife and his best friend being banged somewhere in the sewers by the whole town, which led to some incident where he "adopted" his bff's daughter afterwards and ended with some retrograde amnesia or some stuff. So he began to write the stuff that happened as a giga cope mechanism but it didn't really work out, so he's been whining for 20 years about something he probably caused, without seeing a therapist. Or it did, but he has run out of stories to tell.
That or he was being groomed to take that Master's role but some shit hit the fan and he had to run away.
Anyway, now he's back, still whining, and he has decided to domme everything that moves in the academy town.
Could be fun/ny.
