The Kuru-Kuru 11 Onahole is a hefty, chunky masturbator toy with 11 thick inner spiral swirls. The easy-to-penetrate entrance is balanced by the generously sized zigzag of the vagina, which guides your penis down and down the tunnel to reach a snug uterus chamber that swallows up your glans whole. The toy is pliant and stretchy, so you can really pull and twist it during use, while the skin is made with a special material that improves with age, molding to the shape of your penis!
