A dedicated real estate salesman in bustling Tokyo finds his professional life heating up when he introduces a beautiful couple to a nearby apartment complex. The wife of the family—Chikako Maru—is an absolute vision; her stunning physique is exactly what every man dreams of possessing. From afar during daily encounters while she changes clothes near his office space or apartment doorframe,
he quickly observes that Chikako’s husband struggles with stamina. This knowledge fuels his secret fantasies about her frequent solo sessions of self-pleasure. One afternoon transforms everything when Chikako asks for his help fixing a leaky faucet in their bathroom. Seizing this perfect opportunity to indulge his desire,
the salesman pins her down for intense kissing and hands-on exploration. Rather than resisting the advances of the younger man, Chikako actively encourages him! Deciding to satisfy her deep-seated loneliness and surging sexual cravings, he uses his own impressive member to finally give her the passionate encounter she craves.
