“They’re light red!”

@Joey  
That would be fun. I think they’re probably hers though. Doesn’t mean you can’t give her some playful teasing about her cute ruffle n bow panties to make her blush though

@Joey  
Um, no … that’s just running it xD  
It should be her cute panties

Damn she’s cute!

@Liggliluff  
Or maybe someone tied her forelegs up first, then slipped the panties on her after she wasn’t able to do anything about it just to make her look even cuter!

I presume this is a universe where they wear clothes,  
and someone has undressed Rainbow to expose her panties.

@Joey  
I’ve said it before;
 
Rainbow Dash. Secretly cutest pony since season 1. :P

Oh god, she looks so adorable in pink panties! Especially when she’s blushing! Doubly so when she’s tied up and unable to do anything about it <3

 
Puncess Carlostia: ‘No, Rainbow Dash can’t see you at the moment. I’m afraid she’s a little tied up at the moment.. A certain Zebra is sitting on her head, as she’s on top. Why is Zecora doing this and not I: Princess Molestia? Because I’m into “50 Shades of Grey”. Yes, that’s right: while Zecora sits on the head of a tied-up Rainbow Dash, I’m into her, via certain… ‘device’ made specifically for larger equines such as your not so good self: with a strapone..
 
Anyway, sorry to string you along, as I’m having to cut the line: that used to suspend the washing, as we’d run out of rope.’

“Why did you put these pants on me?” :P
