elsa's punishment reminded me of one I have used in the past.
Tie a weight on a string to each nipple. The weight should hang no lower than your pussy. Without touching the weights, do 80 toe touches. The weight has to come to rest completely on the floor.
That is 40 for each nipple that went unclamped.
I did the 80 toe touches after I completed elsa's jumping jacks yesterday. I didn't really have weights so I used a basket and put a pair of shoes in it. My nipples did not come unclamped but they were a bit sore after completing the two dares back to back
