The Endurance Test - Arms Overhead, Brush Wheels On Bare Abs And Ribs (Anime Bara)

He volunteered for the endurance test, and the frame does the rest. Padded cuffs lock his wrists high overhead and his ankles to the base, so his bare abs, flanks and lower ribs are stretched wide open and completely out of reach. Two motorised brush wheels roll in and stay there - soft bristles splaying flat against sweaty skin, scrubbing without a pause, shifting from one flank to the other while he twists, hauls against the cuffs and laughs himself hoarse. Different volunteer, different build, different angle, every single time. Every man in this collection is a willing volunteer who agreed to the test. Every scene is 2D hand-drawn anime animation - no real people appear in this video, and all characters are adults.
