The ID Lubricants BackSlide Silicone-based Lube was after two years of research and testing. The result is a special thick silicone-based formula that is one of, if not the thickest lubricants available. This thick, cushiony texture and feel is unlike any other anal lubricant on the market. The ID Lubricants BackSlide Silicone-based Lube contains clove and spilanthes extract which work in conjunction to provide a natural, mild muscle relaxing effect. This allows for ease of penetration as it keeps the anus from unnecessarily contracting while not desensitizing the individual completely.
