Kaori runs a small real estate agency in a downtown neighborhood, having inherited the business from her late father. Despite its modest size, the shop enjoys steady sales thanks to her uniquely aggressive sales approach. One day, a musician visits, requesting a viewing of a soundproof room. Without warning, she silences the man with a kiss, then reaches down to stroke his hardening cock, asking, "Want to test it by making some loud noise?" Her bold tactics keep bringing in contracts, but Kaori struggles with uncontrollable sexual desires. Tormented by her urges, she confides in her subordinate, Uchiumi, as they explore new ways to cope.
