A Trade with Sayer who's half of the trade can be found here:

Eat the Rainbow(Warning, Vore, Macro/Micro, and other such, don't like, don't look)

For his half, he requested a story in which Rainbow Dash get's a bit of an Inflated Ego, along with inflated everything else, courtesy of everyone's favorite Party Mare. Of course, being Pinkie Pie, she tends to take things a little too far, and she also tends to lean on, and even break, a certain wall throughout the fic. Anyway, I hope you enjoy it.
