Unlock your wildest fantasies with the Nice n Naughty Ass Spark Cock Ring with Anal Lock! The Ass Spark brings together the cock ring and anal play in one beautifully crafted stainless steel piece. Featuring a smooth ring, that is attached to a steel rod with a removable anal ball on the end. The rod is held in place with a tube of steel, allowing the ring an ease of movement, and allowing the anal hook to be easily adjusted for an unforgettable experience. The Ball can be unscrewed, should you wish to increase the size later. We recommend cleaning with warm soapy water and applying an antibacterial toy cleaner afterwards. Being stainless steel, the anal lock can be used with any of your favourite lubricants. Stimulate yourself and your partner to new heights! Top measuring tip: With an erect penis, take a piece of string and wrap it around the base, behind the balls. Measure this string to the nearest millimetre. This will give you the circumference, so divide this by (3. 14) for the diameter. If you are between sizes, size down for a snug fit. Brand: Nice 'n' Naughty. Colour: Silver.
