The Wolf Claws At My Stomach (Tearing From The Inside Out)

Omega Tony Stark is used to the occasional bad day. He has them all the time, so it shouldn't be that big of a deal. However, when his son Peter comes home smelling of fear and blood, the father soon realizes that his worst day isn't when he is upset himself.

No. The worst days are when his pup is hurt and Tony can't do anything about it.

Almost.
