A/N: This is a gift for reindeergamesbitch from Tumblr in exchange for making something for me. She requested biting, and who am I to deny such a lovely request when it comes to my favorite pairing?
Showering with the Arc Reactor in his chest would have been an unnecessary chore for anyone that was not Tony Stark. Had the core been inserted into the chest of anyone but Tony, the wires would have stuck out and possibly shorted while being drenched in the scalding rain. But his precise handwork made an air-tight seal around the insertion area and prevented any leaks. The daily task of washing up did not endanger his life.
When he cut off the stream of molten water, the shower curtain was pulled away and he stepped into a veil of steam that had risen with the temperature. A towel was quickly wrapped around his waist and he wiped a hand across one of the large mirrors to take a look at himself. He had a thin layer of gray stubble that was beginning to poke out from the unshaven pores along his neatly-trimmed design and his hair was flat and weighed down with water. He decided to shave when the threat of him slicing his neck open wasn't present with the condensation fogging the mirror.
He opened the door and the steam rushed out of the bathroom behind him. He almost looked as though he was emerging from another world and stepped in front of a clear mirror to get a better look at himself. A red line rounding his shoulder above his deltoid muscle stuck out on his tanned skin like a sore thumb. He leaned towards the glass to get a better look at the injury.
The line was large enough for a man's mouth to have been, and small, raised bumps suggested the marks were made by teeth. And Tony knew exactly whose choppers had taken a bite out of him that left him with such an injury. He could add it to the other white rings decorating his body once it had healed. How many scars does that make now? Sixteen? Seventeen? Forty-eight? Tony couldn't remember. He had lost count days ago.
The towel was replaced with a pair of light boxers and blue jeans. He yanked on an old black tank top with an Reactor-size hole that had been sloppily cut out of the fabric. The glow of it lit up the room as he threw the towel into a laundry hamper and left the room for the lit living room. It was empty and quiet except for the light snoring of a certain Norse God lying across the couch.
Tony's first reaction upon walking upon his sleeping form should have been surprise (after all, he didn't remember the god asking permission to sleep over), but the god was too tall for the couch to lie down flat so he had tucked into himself slightly to fit and one leg was dangling over the edge. He had to pause to get his laughter under control before clearing his throat and approaching.
"Hey, Reindeer Games!" he called, kicking the hanging appendage lightly. "I've got beef with you. Open your eyes. Hey." He jabbed at the god's boot again, but his eyes remained shut. The thin black brows pulled together slightly as his brain registered a disturbance, but he remained in his curled position.
"Hey!" Tony raised his voice and his foot, kicking at the exposed backside. This caused a little more of a reaction as the long lashes shadowing the sleeper's cheeks fluttered. "I said open your eyes."
"I am not deaf, Tony Stark," came the cool reply, and eyelids rose to reveal eyes as clear as the snow drifting down from outside. They adjusted to the light of the morning before landing on Tony's face. Flushed lips pulled into a fox-like smile. "I can hear quite well."
"Good. Then let me ask you a few questions, Loki." Tony put his hands on his hips as Loki shifted himself into a sitting position, nonchalantly rubbing the sleep from his tired eyes. "First, I want to know why you're sleeping on my couch." He held a hand open towards his bedroom. "I have a bed specifically to avoid that situation."
"I did not realize the invitation was open." Loki's brow rose. He would definitely remember that the next time he wanted some time with the man of iron.
"It has limited access for certain people." Tony cleared his throat and his head of thoughts to get Loki into bed with him again and moved on to his next question. "I also want to know what the hell is with you and your teeth."
"My teeth?" Loki made a face that disappeared as quickly as had appeared. "I am not quite sure what you're asking."
"This." Tony gestured to the red ring on his deltoid. "Why is it that you have the urge to bite me every time we have sex? I've got so many scars from your teeth I look like a fucking polka-dotted bow tie."
"Well, you bend as easily as a tie." Loki licked his lips sensually and Tony's face turned into a beet. He glared as Loki chuckled and bit his tongue. "I apologize. That was rather uncalled for."
"But, it's true." Tony frowned. "On a more serious note, I want the biting to stop. Pepper's going to notice one day, and when she does, my head will not be the only one rolling across the floor. You'll get roped up in it, too. And then Thor will bring me back just to kick my ass for getting you killed."
Loki laughed again and stood. Gods, how the hell did he get so tall? The Frost Giant genes in him must have been one of the factors, and if he had been born a runt, as Thor had mentioned to him in Loki's absence, there was no telling what a properly-developed member of the race looked like. They must have been damn monsters.
Loki stood over him by at least four inches. At least. Tony only managed to reach the bottom of his nose, which gave him a great view of the god's nostrils if he stood right underneath him and looked up. Tony locked eyes with him and gave him a hard, stern look. Loki gave it right back, but he managed to look like a feral cat driving its prey into a corner.
"There is a very easy solution to this problem, Tony Stark," he said in a low, husky breath, quickly closing the distance between the two of them. His legs were long and easily gained ground without much effort on his part. Tony realized this very quickly and began to take steps backwards. Where Loki took one step Tony had to take three to keep up the pace.
"Your choices are simple," he said, leaning down as he moved in closer. "You can either drop your little human female and save yourself the trouble of having to run around to hide these rendezvous we have; or, you can cut your ties with me, end this little tango of ours, and you won't have to worry about these nice, lovely little bite marks I've bestowed upon you ever again."
Tony felt his back hit the wall as Loki bent down, running a cold hand over the bite mark. It stung as his ice-cold fingertips danced around the circle of torn flesh. Tony hissed as a small, raw portion of it was grated by Loki's touch. Loki smiled as Tony tried his best to resist the advances, but once Loki's knee began to grind slowly against him he lost all rational thought. A guttural moan erupted from the back of Tony's throat.
Loki bent down and closed off what distance was left between them. He claimed Tony's mouth hungrily with his lips, pushing Tony flat against the wall to ensure no chance of escape. The fought for dominance over the kiss, but Tony knew he had already lost the battle as his legs began to quiver with the dancing of their tongues. The god's hands were everywhere and nowhere on Tony's body. He could feel them moving across his hip and down his leg one second, and the next they were across his face and down his neck and chest. He couldn't pinpoint where they were to grab hold of them. As soon as he located them, they were gone and moving to their next destination. He couldn't stop them.
Loki's smiling against his lips told him that the damned giant knew exactly what it was he did to Tony. He didn't have to hide anything because he wouldn't be able to. The rough kiss against his lips had left him breathless and his head reeling enough that he panted and swallowed with his head leaning heavy against the wall as Loki's lips searched his skin for its weak points. He could feel his lips, his teeth grating his skin, his tongue touching and tasting every inch of his flesh. Tony tasted bitterly of soap and face wash and water, but it was a familiar, sultry taste to him, and he moaned into Tony's neck.
Then there was pain. It was sharp and numbing and Tony ripped himself away, glaring at his lover, the fucking God of Mischief, he remembered, as he touched at his neck where the pain had radiated from. Loki licked a drop of scarlet off of his bottom lip as Tony reached up towards his neck and watched as his fingers came away red. Blood.
"Loki . . .," Tony growled, and Loki looked towards him with a smirk, flicking his tongue out over his lip. "Again with the . . ."
Loki nipped at his bottom lip to shut him up, still wearing that same damn smirk Tony had always seen him with. Tony was breathless, tired from fighting, and his head was reeling from the lack of oxygen. He closed his eyes as Loki made work of his neck again and ran his hands through the coal-black tendrils of hair held firmly in place by, what, fucking magic? Tony didn't feel the greasy slickness that came with gels or other hair products. He'd have to learn Loki's secret.
And fuck it with the biting again! Tony groaned as Loki's tongue grazed across the newly-made bite mark with a wet tongue before digging his choppers into Tony's flesh again. He growled and dug his fingers hard into Loki's shoulders. "Enough!" Tony pushed against Loki's shoulders. Although the god could have ignored him and continued his work with Tony's neck, Loki gave into his demands and pulled himself away, a spot of blood at his mouth's corner.
"Is something wrong, Tony? I thought you quite enjoyed this game of ours," he whispered. Gods, what that voice did to him. Tony breathed heavily to calm himself, and his loins, as Loki stared at him and waited for his response. Maybe Thor could do without a little brother. If he was any trouble on Asgard, Thor might not mind the absence too much.
"I don't mind the 'game,'" Tony answered, throwing up the air quotations. "What I don't like is all the damn biting you've been doing lately. Is there a sudden fetish interest that I need to know about before I decide whether or not I'll let you take me to bed again?"
"Is there something wrong with my biting?" Loki challenged; his right brow cocked perfectly on his wide forehead. "You didn't seem to mind it so much last night when I was fucking you senseless . . ."
Loki's eyes narrowed into thin slits and Tony suddenly felt completely naked before the god. He wanted to go back to the bedroom and fetch a blanket to cover himself up with, but even that action would be in vain. He would still be bare under the god's eyes. There was no denying him that.
"I didn't mind it because I didn't have any idea you'd leave fucking scars." Tony wiped at the blood on his neck and could feel it smear and harden across his collarbone. "Pepper is going to notice these, and I don't have a story to cover it." He felt the gooey substance thicken on his fingertips.
Loki did not appreciate the sentiment in Tony's voice at all when he spoke of this damned woman who had changed him from the shameless Anthony Stark into the Anthony Stark that was beginning to get a grasp on humility. He preferred the Stark that rolled and writhed beneath him as they fought and sought to dominate the other, but both of them knew that Loki would always come out on top. Anthony loved being dominated, much like every human being on this earth did. The ego-bruising simply made it more pleasurable for him.
"How. Dare. You." Although Loki's tone wasn't harsh in his head, when he spoke, it sounded as though the words had been drenched in acid and were knives driving through Tony's chest. "How dare you speak of that woman in front of me, during this." Loki reached around Tony's hips to take one of his cheeks in his hands, giving it a painful squeeze. Tony groaned, but a smirk played over his lips.
"Oh, are you angry?" he prodded, leaning up to kiss at Loki's exposed neck. "Perfect."
There was a sharp intake of breath from Loki as Tony opened his mouth and bit down hard on Loki's neck. The pale flesh reddened as blood seeped from the wounds and Loki let out a growl as Tony lapped at the blood and kissed it in apology. Loki didn't seem to mind domination from time to time, Tony noticed.
"There." He pulled away to sneer at the god in front of him. "One down, sixteen to go. Is there anywhere in particular you'd like the others?"
Blue eyes flashed at the invitation and Loki conquered Tony's mouth once again. As the two separated, Loki's hand still grasping the shorter man's ass in a painful grip, he pressed them further against the wall, and when they were out of breath, Loki muttered, "Is that invitation to your bed from earlier still open, or has my biting pissed you off enough to force me to take you over the kitchen table?"
Tony cracked a grin and ground his hips into Loki's. "You could take me over the kitchen table if you wished, but it'd be quite uncomfortable to sleep on afterwards."
