Yui is in a fresh relationship with Naoya, but things remain innocent between them. Her world collapses when her past sexual partner reappears and recognizes her. Before dating Naoya, Yui had a impulsive sexual experience with this older man out of curiosity about sex.

He now uses that secret as leverage, threatening to tell her boyfriend everything unless she submits to his demands. Reluctantly, Yui finds herself committing more forbidden acts behind Naoya’s back — each encounter deeper and riskier than the last. Guilt, pleasure, and fear mix as her “secrets” multiply inside her, both literally and figuratively.

This hentai OVA explores themes of blackmail, cheating, and reluctant submission with intense erotic scenes and emotional conflict. Fans of netorare (NTR), coercion, and creampie-focused stories will find it highly appealing. The animation faithfully adapts the doujinshi’s popular art and story, delivering high production values typical of Pink Pineapple releases.
