Did something fun and thought I would share.
Place the key to your handcuffs under the dirty dishes.
Attach the nipple clamp chain to the middle of the handcuffs. Small padlocks are good for this.
Attach the nipple clamps to the nipples.
Lock the handcuffs on your wrists in front of you.
Now you have to wash the dishes or rip off the nipple clamps.
Have fun!
