Evil Virgin

A pharmaceutical company produces a product designed to enhance male sexual desire and is conducting research to improve it. The company's president hires a succubus for this purpose, as these beings are known for their strong sexual energy and influence over men. The employees expect a seductive, fox-like woman, but the succubus who arrives is a young girl named Yamashita Madoka, who appears very innocent and pure. The employees are uncertain how she will perform in her role, given her apparent lack of experience. The question remains whether Madoka can be effective in her position despite being a virgin.
