I'm a detective in an elite investigative unit where everyone else is a high-achieving prodigy on the fast track to promotion—except me. I've always been the underperformer, standing out for all the wrong reasons. My strict female superior, Risa Tsukitsu, constantly reprimands me. But one day, she suddenly gets completely ignored by the entire team. Why? Determined to uncover the truth, I go undercover, openly flaunting my erect cock as I fool around during the investigation. Though clearly disgusted, Risa can't object—after all, you're the one who started it, aren't you? Even though she sees right through me, I act like an invisible man, freely penetrating her and filling her with creampie after creampie. Unsurprisingly, the mission fails and I get captured by criminals. But I manage to survive by offering up Senpai Risa as a substitute sex slave and cumdump.
