START-639 Mana Sakura, a real estate agent returning to work after eight years, seduces the boyfriend of a couple viewing a property for cohabitation and gets him to have raw, unprotected sex with her.

It has been about eight years since Mana quit her job—a departure that followed a period of repeatedly crossing professional boundaries to engage in illicit affairs, all sparked by the abnormal sexual desire she felt watching happy couples tour properties. Now back at work, she finds herself alone in a vacant unit; recalling her past compulsions, she resumes her hunt for a "cock-filled property" to satisfy her lust. She is a lewd real estate agent, addicted to the thrill of stealing a man's body from his girlfriend and driven by an insatiable urge to be filled deep inside.
