on the soles of my feet

One of my favorite tickling tropes is when someone who’s hella ticklish has to be written on/ painted on and they can’t sit still. Or they’re being used as a canvas and they have to be tied down and they’re just cackling madly. Painting and drawing on their sensitive belly and the brush gets dipped into their bellybutton and they lose it. AUGHH SO CUTE. Someone abusing their poor feet and writing “tickle me” on their soles. Just end me.
