After five years of living together with her boyfriend, Anri finds their sex life reduced to a monthly routine, leaving her increasingly dissatisfied and emotionally restless. Beneath her quiet demeanor, complex desires and longings have begun to surface—feelings that can't simply be dismissed as mere frustration. Whispering shyly, "It's... embarrassing," her already exposed groin betrays her, dripping with arousal from self-pleasure. Even when penetrated with a long penis, she loses herself gracefully, her refined reactions perhaps reflecting her upbringing. "Let's take a short break..." she says, only to soon beg for more. As the time for her boyfriend's return draws near, will she be caught? Her inner turmoil and secret yearnings are vividly portrayed throughout this work.
