Aphrodisiac investigator Ichika Mogami receives a sexy mission. A seasoned detective, she has faced countless dangerous assignments before. But this time, things take an unexpected turn—she gets captured. Her body tightly bound by ropes, immobilized and helpless. Under these conditions, her training begins with a powerful pleasure-inducing drug. In this den of erotic torment, moans, screams, and repeated orgasms echo endlessly. As the torturous ordeal continues, blurring her vision and breaking her will, she resists—yet each physical reaction only tightens the coarse ropes, gradually dissolving her reason. Will she inevitably fall into becoming a mere cumdump for pleasure?
