A project where an ordinary man who has a crush on a female coworker hires us to help bring them together. This time, the target is Ms. Mizushima, a second-year employee at an information processing services company. She doesn't have a boyfriend and secretly harbors feelings for her senior colleague, Nishizaki, who always sits next to her at company drinking parties. Nishizaki is kind, knowledgeable about computers, reliable, and has a gentle, easygoing personality. However, due to frequent overtime and a low take-home salary, she often looks slightly dissatisfied. When she drinks, she becomes cheerful and laughs easily—but her hidden struggle is that alcohol also makes her sexually aroused.
After work, the conspirator approaches Mizushima and invites her to join him and Nishizaki for drinks, and the three head to an izakaya. As the alcohol flows, the conversation turns to relationships. Nishizaki reveals she doesn't have a girlfriend and jokes that her age equals the number of years she's been single. At that moment, the conspirator brings up a request for a monitor survey from a client, asking for their cooperation. When Mizushima hears there's a generous payment—more than a typical part-time job—her eyes light up. She readily agrees upon learning it only takes a short time and includes taxi fare, and they head to a hotel.
The excited Mizushima is introduced to the "monitoring device"—a masturbator—and appears slightly hesitant at first. But after an explanation, she understands: "So this is the kind of monitoring?" Realizing the payment is substantial, she agrees to participate. They begin testing immediately. To make it worthwhile, the conspirator suggests Nishizaki try it too, removing her pants to experience it firsthand. Nishizaki squeals with delight, visibly aroused, and her clit swells into a full erection. They then ask her to try the female version, moving a vibrator from her shoulders down to her chest, and finally to her groin. Initially, she refuses, but when told the payment won't increase, she reluctantly agrees. As the vibrator pulses against her, her body jerks uncontrollably—until she finally climaxes.
Seizing the moment, the conspirator claims an emergency and leaves the room, leaving the two women alone. With Mizushima now fully turned on, they move to the bed. The hidden camera captures every lewd moment of what unfolds in the hotel's private room—an unmistakably arousing experience from start to finish.
