All I can remember is one scene, where the female protagonist kisses her sister then she goes to sleep. While her sister masterbates on the couch. I know it's not much to go off of but its been bugging me forever that I can't find it again.
might be this one https://f95zone.to/threads/the-lost-chapters-v0-4a-asura-interactive.70111/
if i remember it right the sister has dark hair and the scene is at the end of one of the chapters (if you are on her route, if you sleep whit the girl in pic nr 2 or the last pic (one of them atlest) then i think she gets mad at you and you dont get the scene if i remember it right )
