She offers a surprised Verawonder a foot massage and she agrees, because basically she is stuck in bed, and maybe it will make her foot feel better.
Soon she realizes the nurse has other things in mind as she starts tickling Verawonders casted foot relentlessly so that her long toes wiggle, which the nurse just loves to see! The cast foot is easier to tickle because the plaster keeps her leg stiff and out so the nurse has easy access and verawonder can't pull it away however much she wants to.
Her good foot is a different issue and the nurse feels it best to tie the big toe of her good foot to the traction bar so that she can't pull it away while she tickles it relentlessly and then movs on to both feet.
Then the nurse "rewards" verwonder by untying her big toe, but that's because she has other foot abuse in mind!
The teacher knows how to give tickle abuse as well.
