A European research group has published a report that the G-spot does not exist. He argued that the erogenous zone of the female genitalia is not limited to one place like the G-spot, but is more complex, and proposed the concept of the erogenous zone called the clitoris-urethral-vaginal complex = CUV complex. A new project to experience such a CUV! The test subject is Yui Hatano, also known as Hatano from Sekai. Having developed all kinds of erogenous zones, she plunges into an unexperienced zone of super pleasure!
