The Lust Grimoire

A stumbled-upon book drops you into a hidden magical world, and rather than the wide-eyed hero, you end up posing as a mage who isn't quite what he claims to be. That impostor angle keeps things a little wry even when the setup is played straight.

You take charge of a group of students inside a magical order, guiding their training and deciding how far you let their curiosity run. The order itself comes with its own secrets and trials, so your role is as much about steering a small institution as it is about any one girl.

Day to day, it plays like a management sim wrapped around dating-sim choices: you assign lessons, nudge personalities that range from shy to domineering, and pick dialogue that either keeps things proper or tips a student toward bolder experiments with her abilities. Point-and-click puzzles break up the routine, and outcomes shift depending on how much corruption versus caution you feed into each girl's training.
