Rarity's Pregnant, and Spike's the Father!

Despite the laws of nature, the divine, and whatever else balances the tenuous forces of the universe... Rarity and Spike are having a baby.

Part of the Anarchyverse. Reading the previous story is not required.

It can't be possible, can it? It can't. Not according to modern Equestrian Science, Magic, and Medical research, anyway. And yet, it's happened. Cross-species hybridization, and between a Pony and a Dragon, of all things.
