Juri Nagano, a 33-year-old office worker, had just broken up with her boyfriend and was at rock bottom. What saved her from dark days was a cat. While she was dreaming of living with a cat one day, she accidentally met (picked up?) a man in the bush, who she thought was a cat. She decided to rescue him since he seemed weak, but he suggested "Are you interested in keeping me?"... Since he won't say his name, Juri named him "Yun,'' and their shared life together began. Yun has a friendly and cheerful personality. Sometimes, he shows his male side. Whenever he gets turned on, or horny, he devours juri's body, licking her like an animal and making her come all over until she can't think about anything else... The two have both reached above the border line. What is going to happen next!?
