Chinese balls were originally two spheres containing two beads linked with a strings and once they are inserted inside the vagina, create excitation with women by helping them lubricate. Indeed, when the beads move inside, the spheres knock into one another, alone causing slight excitation, which usually increases lubrication. These balls are inserted before sex in order to prepare the woman for a possible relation with a lover who is sometimes too eager, or simply to heighten please before any real relation. Of course, the balls must be removed before penetration. La Clé du Plaisir is Canada's premium sex shop!
