Yuki Mori, a 21-year-old college student finishing his tech degree, faces financial hardship until he discovers an unexpected opportunity: a lucrative position as a "Private Servicing Assistant" with flexible hours. Assuming it's straightforward work, he eagerly accepts—only to discover the role is far from what he imagined. His employer is Katashi Kurica, a 32-year-old powerhouse CEO of Kurica Fashion House. Stunning and commanding, Katashi operates by her own rules and has already decided what she wants from Yuki. When he nervously signs the contract, she makes her intentions unmistakably clear during their first meeting at her penthouse: "You'll be servicing me. Not the floors." For an inexperienced virgin, the proposition is shocking. Yet the compensation is impossible to ignore, and Yuki finds himself drawn into an intoxicating arrangement where his body becomes currency for her desires. As their intimate encounters intensify and deepen, Yuki realizes this job transcends a simple business transaction—it's an immersion into a realm of seduction and erotic exploration. But Katashi is merely the beginning. Tokyo's most desirable and sophisticated women have taken notice of him, and Yuki soon discovers himself pursued by multiple sophisticated partners who crave his attention. In a metropolis where passion reigns supreme, Yuki's world transforms completely as he navigates relationships with Tokyo's most alluring mature women, each encounter pushing boundaries and revealing new dimensions of desire.
