Whip Awaits

I painted this scene a few months ago. I’m German and am trying to describe it in English. I hope this helps.

You can use nipple clips, ropes, or other items. 3= A large stick to which your wrists are secured. 4= A rope encircling your waist; a second rope (connected to the first) runs between your legs from your back to your front. 5= A pulley fixed on the rope between your legs. The rope (6) passes through this pulley. 6= This rope, by passing through the pulley (5), connects your ankles. It is too short for you to stand with both feet flat at the same time. 7= A vertical pole. At the top is a whip that can rotate around the pole. 8= Highly elastic rubber linking the whip to the rear column so it returns. (Perhaps undergarment fabric?) 9= Very stiffly elastic rubber or just a rope connecting one ankle to the whip. When you jump to switch which foot bears your weight, the whip shoots up toward your bottom. Variant: If you are strong, fix your wrists spread out beside your body. This ensures that when switching feet, you cannot support your body weight with your hands. Please play safe! Use different methods to get free!
