Turns out ponying up was a bit more permanent, and a bit more need-inducing, than anyone expected.

After the Fall Formal, everyone who used Equestrian magic wound up as a fully earth-horse sized centaur with some extra equipment. Twilight turned back to normal going through the portal, but the others, including Sunset, had to relocate to the Apple family farm, CHS unable to accommodate their big, virile bodies. They were adjusting well enough, until the spring heat rolled around, shattering their remaining decorum.

Now, they would fuck like mad.
