Siren Song

"The next thing Tony Stark knew he was yanked into the water, the breath squeezed out of his lungs as he was dragged down into the depths, his last sight of that beautiful face twisted in a fanged and triumphant smirk before the world went dark." [An encounter with a mermaid leaves Tony in an awkward position.] Loki/Tony Stark. Frostiron AU. Inspired by kallona's art.
