Every day, the sounds of a woman moaning from next door stirred something deep within Yuka, and she could no longer resist. One day, she learned that her neighbor, Tabyu, was a masseur, and on her husband's suggestion, she allowed him to touch her body. Under his invasive, full-body massage, Yuka gradually grew more sensitive. Her body responded intensely to the stimulation, filling with pleasure. Enthralled by the sensation, she soon found herself accepting Tabyu's next invitation. Her body became increasingly enslaved by ecstasy, transforming her into a pleasure-starved female dog, completely under his control.
