The Maddening Brush (Patreon)

Locked in stocks with a few toes tied is one thing but having your arms pulled back and tied while just the tip of the softest paint brush imaginable barely touching the sole of your foot moving up and down just in the center of the sole makes it all feel like a nightmare as it tickles but then it also leaves that scratchy itchy feeling on that area that you cannot stop. One foot tries to turn in to get the itch and tickling to stop only to find the first and second toes to be tied in a way to make you feel you have some control when you don't. While the third and fourth toe are left free on the foot that is being tickle tortured giving a glimpse of hope thinking they might possibly bend over to stop the brush and itch the area only to find they can just barely wiggle around. This plays crazy mind tricks and could cause anyone to go insane with this type of tickle torture.
