I belong to a certain investigator unit. Everyone around me is an elite and on the road to success, but I'm the only one with low abilities who stands out. Then one day... I was ignored by the whole team at the command of my female boss Tsuki-san, who always scolds me harshly! But wait a minute? If this keeps up with me being ignored no matter what I do...! I came up with a way to get revenge, so I fooled around with my dick out during an important undercover investigation! It's obvious that I don't like it! But... you're the one who started it, so you have no choice but to ignore me, right? I became invisible even though I could see them, so I could do whatever I wanted, including inserting and cumming inside them! Of course, the mission failed and I was captured by the bad guys, but... I was saved when I offered Tsuki-san's nice body as a substitute sex slave!
