A man visits a hair-removal salon run by his wife's friend Momose, whose enormous N-cup breasts have always left him staring. Nervous and aroused, he lies down for treatment while his wife remains nearby. Momose has grown horny from seeing male clients get hard every day, and once she realizes how sensitive he is, she begins teasing him obscenely even with his wife close enough to catch them. His accidental climax leads into secret meetings and creampies at the salon.
