Hey, watchers, got another one from Tahu. We all shared this idea many times when Sweetie Belle is our favorite CMC. For this case, if you have seen this one, http://tahublade7.deviantart.com/art/Luunan-s-Wardrobe-Meme-Sweetie-Belle-502457941 , it's based on her Fall clothing.
Well, he have quite some fun here, the story goes, takes place at a playground, the CMC & Babs join to go upside-down for their panties to be seen. However, Scootaloo is not interested, but later, decide to go for it. But of course, Babs had enough as she's scared of any people seeing them, so she decide to bail out early while Scoo decides to join in. And well, you know the rest.
Enjoy those panty shots, my friends!
