A spank-off is a formal challenge between Mistresses of the Association. It is considered a classic endurance test.


The standard rules see the two competing Mistresses displaying their respective slaves bare-bottomed, then spanking them on the buttocks with a crop, paddle, or any other previously agreed upon instrument until the slave cries out their safe word.[1] The winner is presumably the Mistress whose slave lasts longer.
