The Wheel of Pleasure by Ouch! is a little teaser but can be a pain in the ass when you put up some more pressure. The little pins on the wheel are very sharp and will definitely give you the feeling you are dominated by the one behind the wheel. This toy can change your bedroom into a relaxing massage studio or into a hardcore SM basement. Specifications: - Material: ABS and Stainless Steel Dimensions: 1.42" x 3.15" x 7.28" Weight: 2.12 oz
