The 17th installment of the private training series by the Tuning Club staff has finally arrived! "Rei," married for six months, suffers from a sexless marriage. Despite her voluptuous figure, she's exhausted by her increasingly frustrating daily life. A traumatic training experience at age 16 left her with no positive memories of intimacy since. However, the growing sexual frustration from her passionless marriage drives her to request training once again in order to overcome her trauma. With a youthful and innocent heart, she is led beyond the boundaries of pleasure and pain through rope bondage, embarking on a new and transformative experience.
