A work that deeply explores the essence of pleasure. Sensations bordering on pain—seemingly anything but pleasurable—are gradually transformed into ecstasy under the guidance of skilled dominatrices. This documentary captures that transformation on film. Professional dominatrixes Sarah and Sayu lead a male masochist into profound pleasure through nipple stimulation, anal play, and the slippery interplay of bodily fluids, guiding him toward abnormally intense arousal. The boundaries between BDSM and sensual pleasure blur, merging into a single unified experience.
