fairly off for the day so having issues drawing, tried two things, one was this idea for pony boob used for magic potions, but as a non watcher of the series no ideas came to mind that would make them put their boobs thru this :P. Figured it forms a potion of pony fat for a viscous potion used for… something, no ideas what. MAgic might have been used to give them the boobs in the first place. My anatomy is just bad at the moment.
