Whips.

You prepare her with firm, experienced movements. You pull a red ball gag into her mouth and fix it behind her head. You tie each of her legs and pull over a saw horse, pulling her down with her arms still stretched overhead on the hook and her legs are tied straddling the horse firmly, her little pink pussy on display.

You take a length of rope and bind her breasts with a simple figure eight so the already firm round shapes are tightened like balloons, her soft nipples presented up for your attention.

And then you bring the display case of whips where she can see them, throwing just a handful of water over her face and chest as you walk by, sending her little nipples uncontrollably upright. She flinches angrily, twisting in her tight bondage, quite beautiful in her vulnerability and rebellion.

It might be that you enjoy the very beginning of her training the most of all. You run your hand over the selection of whips.
