This is the perfect sole to restrain tightly, tickle meticulously and ruthlessly, lick furiously, and leave your captive begging for you to stop.
Fingers, feathers, brushes, and other toys will be used on this foot until you practically pass out, a panting, sweating mess.
When you can't take anymore, and to let you catch your breath, I'll just entertain myself with a few games of "this little piggy" with your foot. Of course, that last little piggy still has to go "wee-wee-wee" (tickle, tickle, tickle) all the way home (all over your wide sole).
I don't think you could last, with the fun I would have with this foot, let alone the other one.
