A personal pon pon piece that came into my head over the long weekend.
 
So, Luna while taller then most ponies is still smaller then her older sister Celestia. And in my head canon they share a similar foot size. Which goes to show you how exploitable Luna’s ticklish footsies are.
 
Usually Luna is a complete tickle masochist. If given this situation alone she’d stay there unbound for as long as possible and loving every second.
 
And while she does enjoy the ticklish torment, her Sister teasing and hugging her adds such embarrassment for the poor Princess of the night. A conflict of feelings indeed!
 
As for Celestia, she’s a tickle masochist but also very, very good at taking such punishment. Luna is a tickle masochist who can’t take lots of punishment before squealing.
