Nice work.
I wonder what would happen to Twilight?

We would have loved to see the glorious titjob/boobjob "party" from Pinkie.

Or with Fluttershy, Rainbow Dash/RD, Applejack/AJ, Rarity, and Twilight when they just recently get their sexuality bimbo make-over.

We already know what's going to happen to Twi but imagine she could sense the change in her friends and it's her and shy tracking down the sender while she slowly transform as well lol I hope this doesn't end with Twi. The sisters and side characters need to appear

“Strange things happening? Oh, oh, what is it, what is it?” Pinkie asked, being more and more excited by whatever it was Fluttershy was saying. “Is it a giant monster? An evil enchantress? A wicked invasion of parasprites? Oh, I know, I know! The parasprites are going to war with the breezies over a forbidden love?”

Knowing Pinkie, this could be a sidestory.
