My Sister Is Plain And Modest, But When She Took Off Her Glasses, She Was An Immensely Beautiful Woman, And When I Couldn't Resist And Pressed Her, She Let Me Have A Raw Penetration From Her Bare Bottom For The First Time Inside Her. Emi Nishino

My plain stepsister transformed! With my advice as her younger stepbrother, she became a beauty that everyone turns to look at! But I've had a crush on her since we were kids... Before someone else takes her, I steel myself and confess! I tell her my feelings, but she rejects me because 'we're siblings.' I say, 'Even if we don't insert it, just rubbing together is fine...' and we promise only to do sumata, but of course, it doesn't end there... Once we do it, we can't stop and do it over and over... My stepsister gradually starts to fall for me too...
