I'm reading a fic over on ff.net called The Challenges We Face by Agent Yaoi (https://www.fanfiction.net/s/9313137/1/The-Challenges-We-Face) where Tony is Loki's adopted son. It's a great fic and I highly recommend it. It's got me hoping to find more fics like it.
So, I'm looking for fics where Tony is Loki's son. He could be adopted or actually biologically his son.
Thank you in advance!
