This metallic ball stretcher from the Sinner Gear assortment supplies an additional sturdy sensation. The ball stretcher is heavier than most rubber or siliconen stretchers. You can cool the metallic down or heat it up by placing it in a bowl of water for added sensations. The stretcher will be locked with a screw and may solely be opened with the inlcuded Allen key. This makes the toy very appropriate for an thrilling BDSM recreation. The wearer can not determine when the stretcher is taken off. The Dom retains the important thing, so the sub fully arms over management. Are you up for the problem?
