From the way you kept asking me to untie you, I had a pretty good idea what you had in mind. Even if you managed to run up the stairs, the door was locked, and all you would have done was to give me more reason to punish you. In any case, I was planning to tie you up in a different position anyway. Hmm, I want to see you hanging by your tits...

I untied the string from the clamps on your nipples but left the clamps on, and then I untied both your wrists and your ankles. I disappeared from your view when I walked over to the bench to pick up a flogger and a cattle prod, all the while keeping an eye on you...
