She tries to suck in her belly, only for all the fat to go into her butt.

she’s been eating too many burgers XD

@Background Pony #C42C  
That, is up to you to deicide

@reterusu
 
Who will volunteer?

@Background Pony #C42C  
Yes, of course.  
Willing volunteers only though.  
Anything else would be in ethical.

@reterusu  
So she’ll fatten up others, eh? All in the name of science, of course.

@Background Pony #C42C  
Of course, she needs a bigger sample size to confirm her findings…

@reterusu  
Very nice…

What happens after the testing

@Background Pony #C42C  
Naughty annon, jumping to conclusions

@reterusu  
Oh right, sorry.

@Background Pony #C42C  
Not that!  
Just applying pressure to bellies to test how much they squish.

@reterusu  
Indeed, though since this image is tagged safe, we probably shouldn’t go into what they are going to do when they get there. ;-)

@Background Pony #C42C  
A trip into twilight’s lab?

@reterusu  
Oh ho, I think I can see where they move on from there…

@Background Pony #C42C  
(italics will be used to indicate thoughts. bold will indicate actions or the way something is said.)  
Celestia: muttering Stupid belly. I knew I shouldn’t have ate everything at that diplomatic meeting. I don’t know, this belly feels actually pretty good…  
Twilight: bursts in  
Twilight: talking really fast Look, I’m sorry, I should have kept to a diet and I know that the slope to becoming a fattas is lubricated with lard and…  
Celestia: Twilight.  
Twilight: Yes princess? Oh no, I’m doomed!  
Celestia: moves hands over to her ample belly Look here. I guess I’m not the only one here who is concerned about weight  
Twilight: Is she going to lay that down on me? Or eat me?  
Celestia: Look at how much weight I gained. Do you really think I’d punish you for your weight, when I am the one who weighs more? Twilight, oh how you always panic about impressing me  
Twilight: looks more hopefull Really? It’s not um… Insulting you? Wait, what if there’s some memo I didn’t get and I should be more heavy?  
Celestia: No, it’s all fine. opens her arms Want a hug? If our arms can still reach that is.  
Twilight: walks over, squishes against Celestia’s belly in the hug Huh. Would you mind if I tested your belly fat’s squishyness?  
Celestia:chuckles How do you intend to measure it? Well, I guess it’s a good thing I got this Pudge

@reterusu  
Oh I meant Twilight but now that you mention it, if Twilight does indeed not find a way to hide her gut, whether or not she finds out about Celestia’s when she mets her, Celestia will certainly see hers! So yeah, actually, what will both of them think?

@Background Pony #C42C  
Who?  
Celestia or Twilight?

@reterusu  
What will she think about it?

@Background Pony #C42C  
She will very soon, when she meets up with her at wherever she’s going to.

@reterusu  
Will she find out about I wonder?

@Background Pony #C42C  
Alternatively, she got it in the past week, so twilight hasn’t heard about it yet

@Background Pony #C42C  
It’s hidden from touch, but only for you.  
She’ll feel you contacting it though

@Blissey1  
Does that mean if someone got close enough they could feel where the real edge of it is?

@Background Pony #C42C  
Naw, it’s all illusionary
