Due to the husband's alcoholism and reckless spending, his father enforces severe discipline, leaving his wife, Satori, increasingly frustrated as even marital intimacy is forbidden. Enduring for her husband's rehabilitation, Satori becomes vulnerable as her father-in-law skillfully draws closer. Heightened by abstinence, her sensitivity grows as he overwhelms her with intense kisses and deep, passionate stimulation, soaking her aroused body with pleasure. Unable to resist, Satori gradually begins craving creampie sex with her father-in-law. What began as a rule of restraint spirals into an unexpected awakening of forbidden desire.
