“…in my stomach”

@PUBLIQclopAccountant  
If Celly doesn’t learn to keep them in check the rest of her is gonna get massive too. Well, massiver.

Mares have massive sweet teeth.

@Meanlucario  
If she’s hooking up with anyone, it’s probably someone she thinks her parents would disapprove of. Shady enough that it worries her parents and gets her attention, but not so shady that she’s in actual danger from him. Whatever the horsey equivalent of ‘guy with a motorcycle and maybe a little tattoo’ is. As soon as her mother tells her she went through her own bad boy phase and to have fun, Luna will ditch him.  
Also, she’s kind of a prude.

@lasty  
Seeing that Luna was the one that felt unloved, I think it’s more likely that she would be doing guards under the table.

@TheOtherPinkiePie  
Well, that much is true.

“Uh, the Cookie Monster ate them?”

Busted.

The FiM answer  
Celestia: They, um…(sigh) I ate them, and I’m sorry. I will make you a new batch right away.  
Luna: If you truly wish to make amends with those cookies, there is but one way! You must…eat them with me. I love you, dear sister.  
audience: Awwww!
 
The real siblings answer  
Celestia: In my stomach, bitch! Do somethin’!  
Luna: ugh, you are such a bitch! I can’t have anything without you taking it from me! I hate you!  
Celestia: Yeah, yeah. ‘Waaah, I’m Luna, gimme cookies ‘cause I’m not fat enough yet, eeeeennghh!’.  
Luna: Fuck you, you whore! At least I didn’t let some guard under my tail!  
Celestia: If you tell mom and dad about that, you’re fucking dead!  
Luna: You really did that!? You hooker! Mooooom, guess what your favorite daughter diiiiid!  
Celestia: Luna, seriously, please don’t tell them about that! Mom will kill me and dad will kill him, please don’t!  
Luna: Should’a thought about that before you ate my cookies. Ha ha, bitch! Moooooom!

Celestia: “Murph…mwhaat, cwookikes..?

Give Moonie some. She wants her small tush to be bigger.

“In a better place, sister. Well, better for me anyways.”

Celestia: The same place where I hide my cakes! My belly!

teeeeeeeeeeeeeeeeeeeuh my kookies

“Did you eats them sister?”  
“Maybe….(luna gives a annoyed face)…okay one I had one…Box(Luna gives a very annoyed face).

That “journey to the sun” tag was my best idea ever.

Welp
