Yuka, a full-time housewife, searches for a nearby park after her cat escapes. In the meantime, she reunites with her acquaintance from her school days, Fujita. Fujita, who became lusty for Yuka, who became her wife and increased her sex appeal, approached Yuka pretending to look for a cat together and pushed him down. From that day on, Fujita became more ferocious like a cat in her estrus, and continued to commit Yuka as much as she wanted.
