A housewife named Yumi, married to a strict and controlling husband, meets me through a dating app. Known as a modest and gentle married woman, our first time together was fresh and exciting. But as time passed, I began to feel something was missing, so one day, out of mere curiosity, I suggested trying exhibitionism. Pretending to resist, she became abnormally aroused—her reaction left me utterly shocked. It turns out that due to her repressive marriage, she unconsciously developed an exhibitionist fetish. From that day on, she started getting turned on anywhere, anytime, awakening to our secret exhibitionist encounters.
