Yuka is a full-time housewife who escapes to her cat and searches for a nearby park. During that time, he reunited with his acquaintance Fujita when he was a student. Fujita, who became a wife of a man and was lustful for the appearance of Yuka who became more sensual, pretended to look for a cat together and approached Yuka and pushed it down as it was. From that day onward, Fujita became more ferocious like a cat in estrus and continued to commit Yuka as long as he was lustful.
