My personal favorite is my flogger, love how it can be used to warm up and area and then when twisted can give so much more. My favorite for punishing is my carbon fibre crop which I have found my subs try to hide from me to avoid its use, very funny I think. As for my subs favorite toy, it must be the 240V wand... what an amazing piece of engineering and even the most stubborn of subs always fails to hold their orgasm when it is used.
