A European research group has announced that there is no G-spot. We proposed the concept of a sex band called "Crytris urethral complex = CUV complex" that insists that the sexual zone of female organ is not limited to one place like G spot but more complex. A new plan that allows you to experience such CUVs! The participants were Yui Hatano, a member of Sekai. She has developed all sorts of sensibility bands, and she enters into an unexperienced zone of super-pleasantness!
