Mami works at the same convenience store as her boyfriend. Her recent problem is that she barely feels anything during sex with him, and she's starting to feel a sense of discomfort. One day, while on break, she gets caught having sex and is scolded, but at that moment, she sees the store manager's massive erection. Driven by an intense curiosity about his huge dick and insatiable sexual desire, she can't help but seduce the store manager and relentlessly pursue H even while working.
