This film depicts the relationship between a newly hired male employee and his female coworker, Wakana. The target is Wakana, an office lady handling corporate mobile sales, and the inexperienced newcomer. After a successful business meeting secures a major contract, Wakana agrees to assist with a survey. While showcasing her skills as a capable supervisor, she discovers an unexpected side of the young man—his virginity. Asserting her authority as his superior, she stacks envelopes as a reward, convincing him it's for his own good, ultimately leading to thigh sex as "practice." Carried away by the moment, he ends up penetrating her bareback, resulting in multiple creampie orgasms—an intense drama unfolding between boss and subordinate.
