Minori Kawanami, a female college student with premature sensitivity, undergoes a meticulous 12-hour session of relentless teasing and orgasm denial, pushing her toward a climax more intense than anything she's ever experienced. Starting from the moment she enters the studio, a chastity belt is locked onto her to suppress her desire, while her lewd body is thoroughly tormented to heighten sensitivity. As her arousal gradually builds, she reaches a state where her entire body becomes clit-like in sensitivity. Finally, at the moment of climax, she violently writhes with cock insertion, cumming repeatedly over and over. This is a powerful work showcasing Minori's true, unrestrained self, drawn out only after exhaustive denial and teasing.
