Climb Atop My Walls (слэш)

Tony Stark is the mother that everyone didn't ask for, but got anyway. And it all started with the end of the New York incident. Tony knew that there was something wrong with Loki; from the broken body he walked on Earth with to the lip sewing incident that he was now in.
Now, Tony finds himself facing off a god who is more broken than ever, pregnant and is confused on his relationship with a certain green-eyed god. But he promised that he would protect Loki from everything.
Tony Stark rarely knows when he is doing something good, but this, helping each person find their way home and to happiness, he knows he's good at that.
