OK! So! I have never written a Loki fic before but after the Avengers I really have had this idea for awhile and I can't get it to go away!
Metal
He could taste it. The metal. His mouth forced shut due to this hidious Midgardian contraption. No matter how much he attempted to move his mouth, it only grew tighter. He needed to move his mouth. Let his tongue dance at the lies he could tell. Do something other then sit there for the so called "heroes" to do as they please with him. He could escape but that wouldn't change his current predicament with this mouth piece. The silly litte device was causing him more troubles then the incompetent Avengers realized.
He might have seemed calm to all those who observed but they couldn't see the actual fear in his eyes. He was starting to feel isolated. Alone. It brought back memories when they sown his mouth shut. He can still remember each time they pulled the needle in and then out. Over and over. The blood gushing through his lips. The taste of metal.
He tried to forget. Even now the nightmares never stopped. The fear of never being able to feel the vibrations of his vocal cords. It truly is amusing. They did not realize how they were giving him the worst punishment of all.
Silence.
The taste of metal still lingers in his mouth.
There you have it! Just a little ficlet!
