Yano’s first day at a new lingerie design firm turns into an unexpected sensory overload when he discovers the unique office culture. Assigned to the product development department, he quickly realizes that his female colleagues spend their workday wearing nothing but the company’s latest erotic designs. These outfits are specifically engineered to be revealing, barely covering the essentials while showcasing every curve, leaving Yano struggling to maintain his composure. The office is a hub for testing adult products, ranging from high-end vibrators and dildos to specialized masturbation sleeves, with every employee expected to personally test the items to provide professional feedback on quality and comfort.
Senior colleague Mitsuri Nagahama takes charge of Yano’s orientation, immediately noticing his visible arousal amidst the provocative atmosphere. Dressed in a daring set of lingerie that leaves little to the imagination, Mitsuri decides to turn his discomfort into a hands-on training session. She challenges Yano to test a masturbation sleeve in front of the entire team, aiming to gauge the product's performance under pressure. As the tension in the room peaks and Yano finds himself unable to hide his physical reaction, Mitsuri seizes the opportunity to escalate the situation further, pushing the boundaries of their professional relationship.
Recognizing the need for a more comprehensive product stress test, Mitsuri proposes a direct demonstration. She invites Yano to engage in an intimate encounter, specifically to test the durability and elasticity of the lingerie during intercourse. This bold experiment allows the team to observe how the fabric holds up during intense physical activity, while Yano gets the ultimate hands-on experience with his stunning senior. Watch as this workplace training session transforms into an unforgettable, high-stakes encounter between a new hire and his seductive mentor in this professional JAV setting.
