Fukanshou no Seiso na Hitozuma ga Seikan Massage de Mesu Ochi Netorare

Yuki is a devoted married woman who suffers from frigidity and is unable to feel pleasure during sex with her husband. Seeking a cure for his sake, she visits a specialized massage parlor where a male masseur begins a highly stimulating treatment. Although initially hesitant and guilty, Yuki is overwhelmed by intense physical pleasure and completely succumbs to the masseur's sexual advances. She continues these intense sessions, experiencing unprecedented arousal that permanently alters her body. Ultimately, her husband happily notices her newfound sexual responsiveness at home, completely unaware of the infidelity behind her transformation.
