Hospitalized due to injuries sustained in a workplace accident that left both his arms incapacitated, Kimura found himself unable to masturbate as usual. Instead, he began relieving tension by stimulating his sensitive nipples—until he was caught in the act by Maki, his supervisor's wife and also his assigned nurse. Every time he touched her nipples, Kimura let out pitiful moans, secretly thrilling Maki. She grew increasingly aroused, repeatedly bringing him to climax through relentless nipple play. During his hospitalization, Kimura could do nothing but endure her torment, climaxing over and over under her control. Even after discharge, he remains addicted to the pleasure she gave him, still obsessed with her nipple torture.
