Magnus and His Beautiful Boys by Fanatic_weirdo
When Magnus returns home to see Madzie tied to a chair in the living room and his three favorite boys in the bathroom playing with this make up, he can't help but smile...and then lift the binding spell Max placed on Madzie. He loves his little family, no matter how messy and over-the-top they can be.
I absolutely loved this story! It has a great mix of humor, silliness and fluff, and Magnus and Alec are wonderful, very understanding, fathers. It makes me wish I could be part of the Lightwood-Bane family! Give this quick read a try. I know you won't be disappointed!
