Original Description:
 
Colored in this Twi and Celestia piece for my friend Quill. Cleaned up some of the lineart and tweaked a few things.
 
Twilight is going coocoo for cocopuffs as the phoenix feathers ticklishly rejuvenate and alter her soles and toes. Every blemish and imperfection being healed away to reveal a pair of feet as ticklish as they can possibly be.
 
Poor cutie. Celestia heaps on the tickles with tummy, sides, and armpit assaults’ as well!
