A/N: This is basically a cutesy type drabble for Tony finding about the frost giant part of our green eyed god. Enjoy!
Loki lay on his side, tracing a slim pale finger around the scared skin framing the reactor. The "couple" were lying in bed, their sweat coated bodies cooling. He looked up as Tony shivered, taking his hand away. His hand was caught though and pressed over the powerful circle; he could feel it humming under his hand. Loki looked back up to the mortal.
"So this is what keeps you alive."
Tony tensed but nodded, swallowing deeply.
"Yes."
"It's quite lovely."
"Heh, thanks."
Loki's mind began to wander as they fell silent, thinking to the blue skin and red eyes of his true form. He wondered how this mortal would react. Not by running of course, most likely disgust following the realization that he had been bedding a monster. Because that's all that Loki was. A monster, cursed to crave attention and never receive it. He let his mind continue to wander as he dozed off, his thoughts of ice and snow.
Tony felt the god still on hop of him, his breathing slow and even. He felt something slowly growling colder on his chest, right next to his reactor. Slowly he picked it up. Loki's hand had become a deep royal blue, raised lines and symbols covering the cool colored flesh. His thumb moved over the lines, watching as the color began to spread up the god's arm like frost on glass, moving across his entire body. His other arm moved over the god's back, enjoying the texture and cool temperature.
The god stirred lightly, he could feel something warm moving across his back, tracing almost the pattern of. He sat upright and stared down at the mortal. The soft glow of the reactor seemed to highlight the symbols on his blue skin. He stared down as the tanned thumb ran over the back of his hand.
"You are not disgusted."
"Disgusted? No. I'm a bit surprised but that's all."
"I am hideous. A simple creature from a nightmare."
"You have blue skin and I have a light bulb and magnet in my chest, minor differences."
Loki faltered a bit and allowed himself to be pulled down next to the mortal. They were laid on their sides. He closed his eyes as a calloused hand moved over his skin, sighing as lips joined the hands. Against his will a tear trickled down his cheek, a thin layer of ice following.
Tony pulled the god closer and held him against his chest, one hand running through raven black hair while the other traces the symbols on Loki's back. Sleep was calling to him like it always did when Loki had been around. He wondered if Loki would let him fuck him while his skin was blue. He'd ask him tomorrow.
They were just a couple of misfits trying to fit in by hiding their problems. Loki with his magick, and Tony with the protection of Iron man the hero. Maybe they could finally fit in together.
