Natsuki is an office lady who is well-known in the company for her outstanding style and beauty. Her hated boss secretly films her indecent scenes and blackmails her. At night, he tells her that he will delete the video if she makes him ejaculate, and she tries to make him cum with a handjob, but he won't. On the other hand, she is teased by his insatiable cock, and even though she begs him to cum quickly, saying, "I'll go crazy, so just cum inside me!", he won't let her cum and plays with her. In the end, she falls completely, and her body and Kokoro become her boss's plaything... *This work is a re-edited version of "I was raped all night by my hated boss's devilish cock that never ejaculates..."
