You're playing as "Marten" (pick you own name, of course) a end of high-school student who's about to have some new adventures during his last months of high school, the following summer, and maybe more. You're gonna decide who to hook up with, whether or not having a hot mom and a hot sister is gonna be a problem or an asset, how to get your motorcycle done before the summer, so you'll be able to go on that road-trip you've been planning for a couple years, and generally just trying to work out what you want to do with your life.
Support the original developerThe patch switches the game from landlady / housemate to mother / sister, basically returning the incest version
Just plop the patch.rpy into the game-directory where you installed the game
