This story is a collaboration with Charyb and Azure Dreamer.

Twilight Sparkle isn’t having a good day. She’s stuck to Rainbow Dash’s cart-sized cutie mark, and being flown off to Celestia-knows-where after a botched spell turned Rainbow into an insatiable horny giantess. Twilight’s efforts to fix things just made them worse, resulting in a good chunk of Ponyville being flooded in a torrent of Rainbow’s… juices. And if that wasn't enough, the spell is still in effect, meaning Rainbow’s going to grow even more every time she brags!

Twilight isn’t sure what Rainbow will do next. It could be something crazy, something silly, or something else altogether. Twilight can only wait helplessly as Rainbow travels, completely at a loss to what’s going through her friend’s head.

Certainly there can’t be a method to this madness… can there?
