Kaoru has decided to appear in "Otona no Vinyl Book." Known for her slender body and abundant pheromones, she felt these qualities weren't fully appreciated in her private life, which led her to seek out a genuine sexual experience with a professional male AV actor. Initially shy and reserved, she gradually becomes more aroused as the foreplay intensifies, growing increasingly proactive in pursuing pleasure. Her womb begins to ache with desire, becoming highly sensitive and uncontrollable, ultimately engulfed in the intense pleasure of receiving her first on-camera creampie during her debut AV performance.
