I have been looking for a game and the only thing I remember is the following:
- You are talking to a (female) teacher and the more you go - the more you can do with her. It starts with talking and looking at her and then being able to touch her while being tutored.
- It should be a RenPy game, because I don't play any other platforms.
- The teacher is not the main character - I believe she is an alt. You can visit all kinds of girls, with the teacher being one of them.
