Jun Suehiro, a sheltered young woman raised in a strict household, had her first relationship only after turning twenty and has had minimal sexual experience with just two men. She was largely uninterested in sex and completely unaware of how to masturbate—her nature was pure and naive. She eventually married a man approved by her father, beginning her married life, but found their sex life dull and unsatisfying. Her husband, also inexperienced, lacked skill and passion. Jun began to question whether sex was truly meant to be so unfulfilling. Seeking answers, she turned to the internet and confided in friends, gradually developing a desire to experience real pleasure. Once she became curious, she couldn't rest until she found satisfaction. Determined to discover true climax and physical ecstasy, she decided to appear in a video and explore her own body. In the reunion chapter, Sakei, a man with little experience himself, returns, deeply affected and aroused by their previous encounter, eager to taste that pleasure again. Any guilt she feels toward her husband vanishes in the face of her rising desire. Lost in the throes of passion, Jun abandons restraint, chasing orgasm after orgasm, surrendering to increasingly lewd and uninhibited behavior. The transformation of this innocent woman, driven to wild, uncontrollable ecstasy, reveals once again the overwhelming, almost frightening power of sex.
