FrostIron What is the proper sacrifice for the God of Lies?

FrostIron Loki was cold, always cold, a shadow just barely existing, waiting for sunrise to banish him. Tony wished the wound in his hand was wider, the blood leaking from the rupture hotter, wanted to spill heat and smear it over the shadow to give it form and make it real, to give it something tangible to hold onto when the light came. *citrus* *complete*

After several miraculous strokes of luck Loki somehow finds himself hiding from guards in Thor's bedroom, hoping he won't be discovered for escaping his imprisonment. His older brother wakes and though he's inclined to take Loki back to his cell, he finds himself unable and does something much more unlikely. Thor/Loki Steve/Tony SLASH. You've been warned.
