These princess’s don’t take the threat of tickle torture lightly. Such statements MUST be proven and backed up!
We also get to see a footsize comparison for my anthro canon. As we can see even though Luna is a bit shorter then her big-sister, her feet are in fact longer, sporting slender soles and longer toes.
Of course, Celestia’s soles are wide and super soft with more plump and squeezable toes!
We can also see their preferences in what items they magically hold:
Luna wants to be bound up and squeal as her arches are tickle-tortured.
Celestia wants to moan and gasp as her soles are tickle-pampered.
Who would you play with?
