Glamorous older woman Sumire Mizukawa selects men with highly sensitive nipples and torments them using her long tongue and overwhelming eroticism. She relentlessly targets the recruited sensitive-nipple boys, ultimately demonstrating her superiority through cowgirl-position sex. This entirely improvised, aggressive female-led performance proves her ability to multiply nipple sensitivity several times over. As a participatory documentary featuring amateur male masochist performers, it invites viewers into a new realm of eroticism.
