The Lady Of The Lake and The Impossible Child

One day Merlin and Arthur meet their worst nightmare or is it a blessing in disguise?

Inspired by an actual Arthurian Legend and I recently binge-watched the show so here's a Merlin mpreg, but no shipping (of any kind) I tried to write a story that would be similar to how an episode goes, and I wanted to write an mpreg in which their dynamic didn't change from the show, since I couldn't find any out there - the only ones I found were love stories. Enjoy.
