Last year, Saki came to my house for a parent-teacher visit with my son. As a single mother raising a child on her own, I was touched by her nurturing attitude toward me. With her F-cup breasts swaying, she fussed over me with care—until her naturally lustful side could no longer be contained, and she began initiating sex. Despite being a married woman and holding a respected professional position, Saki harbored a deep exhibitionist fetish and a masochistic personality. She gradually began craving acts of public humiliation at her workplace, and I recorded every moment of her shameful desires.
