Истории Readerxominis

You return to the Slytherin common room late one night, empty, save for Ominis Gaunt asleep on the couch.

There are a few versions of this story. This one is Y/NxOminis. Y/N, Ominis, and Sebastian are Hogwarts professors. This is told in several small scenes, peppered with fluff, and some overlapping with the game.
