I know it is VERY late for this piece.
I've seen this episode a long time ago and the idea came to me, why not give my own spin to it?
And this was also pose practice. My first time trying a pose like this.

Fluttershy is well developed and toned. XD Must be from lifting all those heavy animal feed bags all the time.XD

Enjoy.
