Tsukinoe infiltrates a criminal organization alone to rescue her junior colleague, but loses the fight and is captured. Even rape cannot break the strong-willed agent at first, until her captors discover how sensitive her nipples are and torment them relentlessly. She endures through sheer willpower, but once aphrodisiac is rubbed into her breasts, the intense twisting pleasure makes her shake through an uncontrollable orgasm. Further nipple training leaves her cumming and losing bladder control. The longer she tries to resist, the more the drug-fueled torture awakens her pleasure, until both her reason and her body give way and she is conquered into wildly repeated orgasms.
