I'm not super sure why Cake is tickling her. Maybe it's some kind of training? Or maybe Fionna got stuck in a trap and Cake decided she couldn't pass up the opportunity?
Hell if I know, but who cares! XD
Hope you like!
X'3 This is great, it's good to see Fionna and Cake getting some love~
X3 they both look so well in your style and I like the use of Cake here. morphed feather and natural claws~
XD Cake being the tickler is also within character, in my opinion.
e3e// interesting theories too, I prefer the second one where Cake just couldn't pass it up~
Hehe, and of course, who could blame her for taking advantage of such a tempting situation?
Poor Fionna, already embarrassed at having been trapped like this, and now she's just gotta sit there and take the tickling until Cake's had her fun~
