Keibaku

Overview

Kazuma, a "Master" at a BDSM club, is assigned to learn under Masaki, a blunt but exceptionally skilled rope artist. Their professional relationship gets off to a rocky start when Kazuma, frustrated by Masaki's cold demeanor, lashes out. In response, Masaki insists on Kazuma to first understand the sensation of being the one in the coils. To Kazuma's surprise, the experience is overwhelming; the bite of the rope leaves him with a bittersweet ache that he can't stop thinking about.
