I’ll try to write a story that goes along with the image:
 
(AppleJack is walking through Ponyville in her Twilight Sparkle latex bitchsuit, she tries to find one of her close friends to try and help her out of the suit, but everypony points and laughs at her. Eventually, AppleJack stumbles upon Rainbow Dash relaxing on a cloud on the outskirts of Ponyville)
 
AppleJack: Rainbow! I need a little help!
 
(Rainbow Dash peers over and notices AppleJack in her current position, Rainbow then starts laughing and crying tears of laughter. AppleJack rolls her eyes)
 
AppleJack: It’s not funny Rainbow! Please get me out of this suit!
 
(Rainbow flies down from her cloud and approaches AppleJack, still laughing)
 
Rainbow Dash: Ok ok, tell me, how in the name of Celestia did you decide to wear that? Did you lose a bet or something? Also, why is it in Twilight’s color and why is her cutie mark on the suit?
 
AppleJack: I was just collecting some apples from Sweet Apple Acres, when all of a sudden, some crazy stallion runs up to me and knocks me out with a spade. When I wake up, I’m in the barn and he tells me that he forced me into this suit with permanent glue and I’ll be stuck like this for the rest of my life! Then he ran away, but obviously, I couldn’t catch up with him. So, for the past hour, I’ve been trying to find somepony who’ll help me out of this tight and uncomfortable suit! Could you help me? Or maybe Twilight?
 
(Rainbow Dash tries to contain her laughter and snickers under her breath)
 
AppleJack: It’s not funny Rainbow!! What if that guy was right and I’m stuck in this thing for good!
 
Rainbow Dash: Oh come on AJ, it wouldn’t be THAT bad
 
AppleJack: Are you pulling my leg?! It took me a whole HOUR to get from Sweet Apple Acres to Ponyville, and it’s scorching hot today. I feel like I’m gonna melt if I stay in this horrible thing any longer.
 
Rainbow Dash: One more question. Why is it Twilight themed? Did that nut job say why?
 
AppleJack: He didn’t, no. Explaining this to Twilight is gonna be so embarrassing. Can you be a good pal and please take me to Twilight’s castle? I didn’t want to go on my own, and I need this thing off me ASAP.
 
Rainbow Dash: Woah woah woah! We’re not going ANYWHERE.
 
AppleJack: Rainbow!! Take me to Twilight’s castle! This isn’t funny for Pete’s sake!!
 
Rainbow Dash: It is a LITTLE funny..
 
AppleJack: You wouldn’t think that if you were in my position. Please just take me!
 
Rainbow Dash: Nuh uh, this is too priceless! I wanna show the other girls how funny you look!
 
AppleJack: RAINBOW!!!
 
(Rainbow then out of nowhere then smooches AppleJack’s cheeks)
 
Rainbow Dash: But before we do anything, I wanna have a bit of fun, and I’m sure all the other mares and stallions in Ponyville would too. Then after having a few hours of fun, I MIGHT consider taking you to Twilight’s castle. We’ll see.
 
AppleJack: Oh crud…I’m done for…

@RainbowDash69  
She will tease her about this for years.

@Background Pony #11DF  
It must be so humiliating hehe. Good work Dashie….

She is really enjoying this. And she will enjoy it some more.

@Barhandar  
Keep believing yourself. I know the truth.

@Claw  
No, it’s her mane.

Another lost bet, another punishment.
