Overview

Monaka-chan is an 18-year-old science-minded girl with a deviation score of over 60, but she is also starting an idol career due to her overwhelming cuteness and energetic personality. She is a third-year student who is loved by her boyfriend, but she has a secret: she has sex with an old man live without telling her boyfriend, school, or even her parents. Why take such a risk? Monaka, who is good at studying, seems to understand the structure of society and how to enjoy life in the future. I don't know if she's raping or being raped, but there's a rare raw vagina there. That alone seems to be true.
