Japan's pure Vermilion is a large masturbation device weighing 950g. Normally, a masturbation device of this size has a double-hole design, but NOTOWA deliberately retains only a single hole in order to give players a sense of fleshiness. Use the thick body to tightly wrap the narrow central acupuncture point. This luxurious "thick flesh" is a feeling that can only be achieved with a single hole. You will be able to enjoy the sensation of penetration like a real female body and vagina. The small hole is made of vermilion (vermilion) two-layer material, which is a viscous material like a real person's mucous membrane, and the thick body brings a sense of oppression. The vacuum created by the combination of the two is the true value of pure VERMILION! WARNING: Keep the product away from children.
