Twilight “SciTwi” Sparkle is reformed, but still has her dark magic transformation powers. She and Sunset Shimmer have been dating for a while now, and experimenting with bondage scenarios.
Now “Midnight” Sparkle has discovered another “transformation” spell, and wants to try it out.

Sunset's going to be surprised…

(Just a clopfic, no real set-up or story)

Warning: Contains horsecock
Also, the Epilogue contains accidental pregnancy

More specifically, contains: Light bondage Midnight femdom / Sunset futasub, futanari with a large human/horse hybrid cock, slightly excessive cum, slight dubcon. Also fingering, oral, deepthroat, vaginal. (I think that about covers it)
