Summer with Mia

You the protagonist, are an 18 year old that is about to finish highschool. You live with your mother, father and a hot sister (Mia). The game starts 2 days before the end of school. You are behind in schoolwork and need to catch up on studying to pass. Your parents are going on a trip to France for a week. You are studying late at night when your sister comes home drunk. This is a Ren'Py remake/alternative take on the original RPG Maker game "My Sister Mia".
