Meguri (Minoshima Meguri) has changed jobs to an IT company, and soon after she starts working for the lazy, dried-up, problematic Kaho (Tamaki Kaho). However, it turns out that her senior is actually a good worker, and to her surprise... she's a lesbian. Meguri ends up giving her body to Kaho, and while she's torn between the emotions and pleasure she's experiencing for the first time, she finds herself immersed in the swamp of lesbianism.
