Erika Mizumoto, driven by pent-up desire, was masturbating when her underwear fell onto the balcony below. A young man living downstairs, abnormally sensitive to smells, noticed her actions and discovered what she was doing. As a result, he confronts her. Erika has a highly sensitive body, moaning loudly whenever her nipples are touched. Her wet, slippery pussy is soon stirred vigorously by a thick cock. This incident is revealed to the neighborhood association leaders, spreading the secret throughout the community.
