Naughty Mom

You come home from school to find your mother, Yukari, and one of your delinquent friends, Kurooka, waiting for you in the entrance. She is wearing an unusually low cut dress that makes it abundantly clear she's not wearing a bra. She gives you a forced smile, making a face you haven't seen since you were a kid. Your friend also sports an odd smile. Before you can say anything, your mother pipes up tentatively, "Hey Guest, your friend came over to play some videogames with us, doesn't that sound fun?"
