Mary runs an independent accessories sales company. She suddenly visits a ryokan to pitch her products, but they're about to sign a contract with another firm. The person in charge turns out to be an unexpectedly naive, virgin-like man. This is where her skills as a woman are put to the test. Offering generous services as a contract incentive, she proceeds to sandwich, suck, and bring him to climax. With assistance from an experienced older man who gives his all—performing blowjobs, titty fucks, and handjobs—she smoothly transitions into full intercourse. Through the erotic negotiation tactics of this lustful female CEO, business discussion and sex become one.
