There were tales told of the ‘horses’ when Luna and Celestia were just foals, but now one was right here, brought before them as they had to choose what to do with it. All alicorns being in heat at this time definitely didn’t affect their decision-making by the way.

They decided to just keep it in a spare room for now… Luna is the first to give in to her urges.

I don’t know if it counts as bestiality but this is an anthro fic.

Enjoy!
