One day, a female college student, Rikoto Sugawara, came to an interview for a part-time job where she was asked to take a designated drug for chemical research. Rikin takes medicine after being told that it is not dangerous. Consciousness becomes hazy, and although I resist, I am tied up. Restrained, color torture experiment. In addition, the devil's drug is injected into the buttocks, and the woman's body spree with fingering and anal finger torture. What is the fate of a female college student with attachments and drills? Will I fall prey to the aphrodisiac drug?
