Looking for a game and im slowly going crazy trying to find it

[Jizkili]

I've played this game awhile ago but I cannot remember the name for the life of me.
MC was a janitor in a school where he makes a contract with a demon in a mirror and he takes off sleeping girls clothes and cums on them and it reveals a letter that you need to unlock different stages
If you tried to go too fast they woke up.
I've tried searching w/ school setting and japanese game tags but no dice

If anyone finds this thread please save me lol

Also the thumbnail for the game was a demon staring at you with yellow eyes through a mirror
