New田-kun finds himself in the middle of a complicated situation at work, where office romance is strictly forbidden by his strict supervisor, お父さん. As he's trying to focus on his tasks during lunch break, ねーなーちゃん pops in with a playful challenge, setting the stage for an intense and unexpected journey. His supervisor insists that New田-kun join him on a two-night, three-day business trip to Kyushu, emphasizing the importance of work and the need for New田-kun's presence. But there's more to it than just work — the supervisor hints that New田-kun's absence might make things difficult for him, especially with the mysterious ねーなーちゃん.
As the trip begins, the pressure mounts. New田-kun is expected to endure long hours, late nights, and even a few drinks — all in the name of work. But the real test comes when he's left alone with ねーなーちゃん in a shared room, where the tension between them slowly builds into something more. The supervisor watches from afar, amused by the situation, while New田-kun is caught between duty and desire.
As the days pass, the atmosphere becomes more intimate. The office rules are forgotten, and the lines between work and pleasure blur. New田-kun is teased, challenged, and eventually overwhelmed by the seductive energy around him. ねーなーちゃん’s playful teasing turns into something more intense, and the supervisor’s presence adds to the mix, making New田-kun feel both excited and a little embarrassed.
The journey takes a wild turn as the night deepens, and New田-kun is pushed to his limits. Every moment becomes a test of endurance, from playful challenges to full-on intimacy. The office rules are forgotten, and the only thing that matters is the connection between New田-kun and ねーなーちゃん. As the trip comes to an end, New田-kun realizes that this experience has changed him — and maybe even his relationship with work forever.
