Takes off their Boots and socks.

Who did this?!

Indigo Zap: I gonna teach you to be a pony, Rainbow?  
Rainbow Dash: Neigh!  
Indigo Zap: Good, let’s go! Giddyup!  
(Rainbow Dash starts running in the park, carrying Indigo Zap, holding the reins in Rainbow Dash’s mouth)  
Sugarcoat: Come on, Pinkie Pie! Giddyup, giddyup, giddyup!  
Pinkie Pie: Neigh!  
(Pinkie Pie was race walk in the park, carrying Sugarcoat, holding the reins in Pinkie Pie’s mouth, following Rainbow Dash, carrying Indigo Zap was riding on her back)  
Indigo Zap and Sugarcoat: (to Rainbow Dash and Pinkie Pie) Now rear up and neigh like a horse!  
Rainbow Dash and Pinkie Pie: (both rearing up) NEIGGGGGGHHHHHHHHHHHH!!!  
Indigo Zap and Sugarcoat: (to Rainbow Dash and Pinkie Pie) Good girl! Now let’s race!  
(Cut to Indigo Zap was on Rainbow Dash’s back and Sugarcoat was on Pinkie Pie’s back, was ready to race in the green grass)  
Indigo Zap: Three!  
Sugarcoat: Two!  
Indigo Zap and Sugarcoat: One! Go!  
(Rainbow Dash and Pinkie Pie starts running, carrying Indigo Zap and Sugarcoat, holding the reins in their mouths, raced each other)  
Indigo Zap and Sugarcoat: YEE-HAW!  
Rainbow Dash and Pinkie Pie: NEIGGGGGGHHHHHHHHHHHH!!!!

The punishment for spying is to be ticked mercilessly for hours.
 
Sugar Coat will make the powerless Pinkie laugh while Indigo Zap is going to teach the helpless Rainbow a lesson she will never forget while teasing and taunting her defeated and humiliated rival.
 
The tickling will not stop until they both submit unconditionality and acknowledge the absolute superiority of their victorious captors.

That sounds like a good idea
 
I agree with you

This would have been over by now, but the first thing Dash said once they tried taking her gag off was “What sick kind of school has bondage gear just sitting around?”, and now they’re annoyed again.

@Background Pony #E2AB  
You’re not wrong. I guess that, in the grand scheme of things, the loss of that story doesn’t really matter.  
Besides, the picture is still here.

@Background Pony #5F11  
And nothing of value was lost.

And this is how Dash and Pinkie wound up on ebay.

Alas, the source is now dead.

@RainbowDash69 should do it with the crusaders. Don’t you agree?

Can you do one with the Equestria Girl versions of the Cutie Mark Crusaders using gags and duct tape? Perhaps make Scootaloo look angry, Applebloom look suprised, and SweetieBelle look worried or scared. Can you do it as soon as possible? Maybe the early spring of this year? This month, next month, the month after? Just please do it, for me (and maybe others as well).

Time for lab experiments!

“Don’t worry. We’ll give you back to Celestia once the Games are over.”

Lemon Zest and Sugarcoat?

Well, they can still kick the hell out of their captors from this position!

captured! how amazing… nice and tied up girls~
