At a famous all-girls academy, the elegant Takigawa Hina hides a shocking fetish. Every day after school, she slips away to a secluded area in the park where the thrill of possibly being caught drives her to pee openly and masturbate intensely. Her boyfriend, Yonezu, has been secretly following her for months and knows every detail of her depraved routine—information she has no idea he possesses.

Tired of their ordinary, vanilla sex life, Yonezu finally confronts Hina with the truth. Instead of shame, the revelation ignites their shared perversion. The couple begins engaging in increasingly risky public encounters, pushing boundaries with exhibitionism, outdoor sex, and the adrenaline of near-discovery. What starts as simple voyeurism evolves into mutual exploration of kinks, including creampies, blowjobs, and bolder acts that blur the line between thrill and danger.

This 2017 Bootleg label OVA adaptation of Yoi no Kotaro’s original doujinshi focuses on the erotic tension between an innocent-looking schoolgirl and her boyfriend who unlocks her true “hentai” side. With high-quality animation, uncensored scenes, and a focus on exhibitionism and public play, it delivers intense, character-driven adult entertainment for fans of risky, romantic perversion.

Based on the adult manga by Shouno Kotarou.
