Lucy is always fun to play with and loves a good challenge. Once I have her cuffed down to the pallet, she notices that the copper pipes line up quite nicely with her ass. At the moment the electricity is turned on we both discover she's very sensitive to getting shocked. It only takes a few minutes before hinting the power is on that she thrusts her hips into the air to avoid it. To help her maintain her position, or at least offer a distraction, the magicwand is brought out. The real question is, how long should I keep the power on?
