The debauched older sister Kato Yui's bondage debut work! The sense of humiliation and dominance from being bound, along with the accompanying sexual arousal, expands her inherent masochism, leading to pleasure. Yui indulges in the pleasure of bondage and experiences catharsis. First-time bondage sex, tied to furniture and toyed with. Spread-eagle tie, cocoon tie, forced fellatio, three-person bondage! It's a debut work, but it's all bondage from start to finish!
