Trailing finger up coulson's spine the god laughs at the reaction, perhaps the poor man fears for his dignity, his virtue even. It's laughable really, for Loki there is nothing sexual, only a carnal need to make this man scream, to break his spirit. For a mortal to have battled with a god as many times as this one, was an impressive feat. Loki cannot quite pinpoint what is so special about this man, though his mind screams 'nothing' at him he chooses to ignore it. He cannot admit that it attracts him, to be told no makes him simply want to push harder, there is his conviction.
With a swagger in his step Loki walks around coulson's prone form, coming face to face with him he smirks and presses his palm over the words etched on the agents chest.
"I am going to break you. I won't kill you, I'll simply keep you like a pet and then you may live with the knowledge that you succumbed to me willingly."
