MILD-857 Undercover Investigator Yu Airai

Kamishio's first co-star! In order to rescue the imprisoned investigator Kamisaki, junior Yuu infiltrates enemy territory alone, but ends up falling into the enemy's clever trap and getting caught. Illegal pleasure inducers are forcibly administered and endure despicable sexual torture. Eventually, the medicine works and Yuu becomes a bitch who wants a meat stick with investigator Kamisaki. The fun is doubled if you watch it together with another story Kamishio!
