Riho Fujimori, seeking extra shifts to afford dates and birthday gifts for her boyfriend, is met with a corrupt offer from her store manager: "I'll raise your hourly wage if you give me a blowjob." Though she initially refuses, the manager tempts her with the promise of a significant pay increase, asking, "Don't you think it's a waste to pass up such an opportunity, even just once?" Yielding under pressure, she reluctantly agrees to do it just once. That single act becomes the gateway, drawing her deeper into the manager's web of manipulation and seduction. Though hesitant at first, she gradually begins to feel pleasure, and over time, becomes increasingly involved in lewd acts—eventually succumbing completely, lost in the illicit affair with her manager.
