on dragons wings (слэш)

A loud roar echoed through the streets, though it did not sound like the metallic screeches of the robots. It was too throaty and raw, too alive.
His vision finally cleared and Loki’s eyes widened at the sight that greeted him. In the middle of the street stood a giant dragon, its dark red scales reflecting the sunlight and making them glisten gold where they shifted with its movement. Its head was adorned by a set of horns, blending into its back where two folded wings rested.
Loki’s breath hitched. It was absolutely beautiful.
Or: Tony accidentally shifts during battle and Loki is absolutely smitten.
