Identify Tryna look for a game I played awhile ago

[NeriaSand]

I cannot for the life of me remember the name of this game. I think it had some incestuous elements but I remember pretty clearly that one of the plot points include following a guy who blackmailed your sister or friend and then pretending to be a teacher and fucking his mom. Hope someone can help please... Thankss

Maybe Sisterly Lust, it sounds like how you can deal with the best girls blackmailer.
