I can't remember the name of a game that I played a while back where the MC is a father figure of some sort living in this apartment with a schoolgirl that is very often on her phone. Initially she is very apprehensive to any lewd actions but you slowly break down her barriers to have sex. A notable thing I can remember is a big TV that you could interact with by watching cartoons, news, or past sex scenes in the game and she would react subtly to you doing so.
