Saki, who had just graduated from school, was hired as a new nurse at a hospital in Tokyo. However, there was a rumor about the hospital where she worked: "A hospital where nurses quit easily." A dark shadow lurked within the hospital. One by one, they were violated by tentacles...there was no escape! Everything was being invaded by a swarm of tentacles! The three women, who could only moan, had no choice but to keep cumming over and over again...bukkake, creampie, squirting, anal, double penetration!! They had no choice but to stay there and experience all the pleasure.
