As a Domme I love setting up a predicament bondage scene.
If you are on Fetlife
check out this pic...that was FUN.
-attach heavy weights to genital (lips for W, balls for M) on a rope that is flush with the floor when legs are wide apart.
- cuff wrists and attach either behind back or above head.
- attach nipple clamps joined with a chain and attach a rope to the chain (other end above person) where the rope is taunt when legs are spread.
Ok so now this is what happens: when the person's legs get tired from being spread and the legs come closer it will pull and lift the weights from the genitals. If the person bends the legs downwards then the nipples get pinched and pulled up.
Its a toughy, not for a beginner, but a great one.
