Rin Amatsawa, a spoiled young lady, is obsessed with satisfying her free time, wealth, and intense sexual desires. As a hobby, she uses social media to recruit masochistic men to serve as her personal pets. One day, an M man applies to become her pet. He is forced to swallow her saliva, subjected to face riding and dog licking play, and even has his ejaculation strictly controlled. Eventually, she proceeds to pissing play, leaving him dazed and overwhelmed. Confused and bewildered, he struggles to understand how he ended up in such a situation.
