Film Introduction

My obedient younger sister, Kotone, has a serious and neat personality. But at home, it's my meat urinal. Her body gets wet as the hemp rope digs into her. The lower body becomes sensitive. She is willing to serve the penis "for my brother's sake". A younger sister who feels joy every time she is raised. Masochistic love that accelerates. The whole story of my twisted sexuality.
