So I played this game a while ago. You play as a middle aged guy who by some turn of events starts taking care of a girl. This girl is a blonde who's kinda similar to the main heroine of Dating My Daughter. Anyway, you slooowly start corrupting the girl and in the game you have options to choose whether you want to be gentle with her or dominate her. I believe that the game had an "abbandoned" tag last time I checked (this was maybe two years ago).
