A group of beautiful actresses are collectively induced into a state of erotic hypnosis. The moment a bell rings, they instantly begin touching their crotches, and with just a clap of the hands, their panties gradually become soaked until they're flooded completely. Under the hallucination of Kimutaku, everyone panics, and the studio appears to transform into an ocean—sleeping men become waves, stripping the women's swimsuits off until they're completely naked. This isn't your ordinary mainstream group erotica; packed with unique illusions and intense stimulation, this work is full of surprising, arousing mechanisms from start to finish.
