She was going to make him cum, but he made her cum... Natsuki, a beautiful office lady with an outstanding figure whose good looks have always been the subject of love rumors in the company, is secretly filmed by her hated, creepy boss having a secret rendezvous with her boyfriend in the locker room. The next night, she is called by her boss and told, "I'll delete the video if you make me cum," so she tries to finish it off by making him cum with her hand, but he doesn't cum at all... On top of that, she is made to cum many times by his insatiable dick, and even though she begs him, "If you make me cum anymore, I'll go crazy, so please cum inside me, please cum quickly...", she is toyed with by the mean boss who doesn't cum. And in the end, Natsuki is trained to the point of being completely corrupted, saying, "I want to keep this dick in me forever, so please don't cum!!" and becomes the boss's plaything in both Kokoro and body...
