Well, Liz Rainbow does not like nipple clamps! She hates them! Which makes her a perfect candidate for our 2kg weight challenge. Can she move away with 2 kilograms of steel attached to her nipples? Probably not! But what if she just took off the nipple clamps? Well, we have a perfect device to prevent that: the Ballet Stocks (or Ape Hangers, or Overhead Stocks, we’re still not sure about the name). Liz can’t take off the clamps, and she can’t run away. It’s perfect metal bondage!
