Dojo Discipline - Barefoot Jocks In The Stocks, Soles Up (Anime Bara, 17 Scenes)

Inside a traditional wooden dojo, young muscular martial artists are locked ankle-first into low wooden foot stocks, bare soles turned square to the camera and completely exposed. Wrists tied behind their backs, they have nowhere to go. Motorised brush cylinders roll slowly across both arches and heels, bristles splaying and pressing into the skin, contact never breaking for a second. They strain against the stocks, yank at the wood, and laugh out loud the whole way through. Sweat-shined soles, warm lamplight, paper screens, and the steady whirr of the rollers. 17 different scenes, every one a different man in the stocks. Every man here is a willing volunteer who set the terms himself. 2D anime bara animation - hand-drawn style, no real people, no dialogue.
