A girl named Yura has always been passionate about animals since she was little. She dreams of becoming a pet groomer and gets hired at her favorite pet shop after an interview. However, the store owner tricks her into being kidnapped and subjected to brutal sexual torture. Wearing a collar like a dog, she endures humiliating practical exams involving anal penetration and cum swallowing. Her body covered in urine and semen, she's locked up in a cage where she suffers through various forms of degradation such as object insertion, enema play, and forced drinking of urine. Despite her innocent appearance, Yura secretly desires to be completely dominated by men and becomes their plaything. As she submits to their perverse fantasies, her body absorbs their mark, making her truly their pet.
