OCxOC and also OCxPony
HiE fic, of course…

Cyrus has been living in ponyville for quite a while now, having grown accustomed to the changed life he now has. With a modest job as a waiter for the Sugarcube corner with the element of laughter and the occasional task of helping the Apple family, Cyrus's daily life seemed as normal as it could be, minus the talking ponies of course.

But, during one of his daily walks along the outskirts of the town, he notices a small building that seemed like no other, due to it being rather decrepit yet functional for someone to live in.

He enters it to find a mare. Just a mare on a bed. What she was doing there was beyond him.

And that mare will be the one to change his life, and he will be the one to change her's.
