Oh I’m rather fond of this situation here

What if the artist tried a weight gain animation

@evan555alpha
 
It’s the same image as before. I just smoothed out the animation a bit. Someone should merge them.

Seems like the more she runs the more fat she gets….. nice.

This is incredible.

More? More is good. Very good~

♫ Go Luna Go. Go Luna Go Go Go. ♫

Lol, I love coming up on these pics. It’s where I get to voice my different fetishes and say that Celestia’s a total bombshell here! XD

I like this because Luna is fat, but hate it because she’s gonna lose it. Why you do this to me Stormcaller?

Luna should just keep that beer gut and just be chunky like most girls these days.

I want to snuggle Luna so badly!

@Beau Skunky  
Now that’s edgy! XD

Yeah move that chub…~

This sums up what I look like on a treadmill….. except it would be alot more wheezing falling and dying.

Luna is Thicc and I love it!

@Malvolio  
Yeah, Celestia should eat more, she’s too skinny. She needs to be nice, and jiggly like her sister.

How the fuck can you even allow your body to look like this?

DOESN’T THAT PHEASANT LOOK PLEASANT

Oh my~  
There isn’t enough yes in the world to praise this!

I’m rooting for you princess!  
To embrace your chub~
