Before I had my metal belts, I wore a leather belt. After awhile, I figured out that if i worked hard enough grinding my pussy against the belt I could eventually cum since the leather is a little flexible. 

Sir put a stop to that by adding this little spiked ball… made it very unpleasant to try to hump anything.  (^=˃ᆺ˂)
