A prostitute I knew. The prostitute I called didn't actually perform, and what turned out to be her domineering female boss was... (Kurokawa Sumire, DASS-201)

Sumire is highly capable at work, but her arrogant personality often leads her to lash out at her subordinate, Sakurai. To relieve stress, Sakurai decides to call a hostess from a brothel. He uses a strange establishment called "The Brothel I Know," and while waiting for his services, he unexpectedly sees Sumire in his home. Initially thinking it's some kind of prank, he is surprised when she approaches him with lewd language and provocative behavior. The next day, after questioning Sumire, he learns that she seems to have no memory of that time at the brothel.
