MIAE-340 A sister and brother who grew up in a family that decided everything through the King's Game, Suigiku Aoi

Film Introduction

In my house, whenever my sister and I have a dispute, we decide it with the King's Game. Sharing snacks, taking turns in the bath, whether to keep a dog or a cat. This rule hasn't changed even as my sister has grown up. The commands are absolute, so anything goes. If I win, she immediately sucks my dick, but if she wins, it turns into handjob from midway through; we engage in this tug-of-war every day.
