Tony Stark walked through his mansion, silently brooding. He had been walking like this, without aim, through the corridors, hallways and rooms of his monumental home. He did that, on occasion, when he felt like everything was becoming too much; The Avengers, Iron Man, Stark industries, the pressure that was on him to invent. Handling all this took its toll on the billionaire, and sometimes just sometimes, he needed an evening where he did nothing. Just pacing back and forth through his halls. He usually did this for hours on end, without saying a single word. Then, after some time, he would call out.

"Jarvis, where am I?"

And there would be an answer.

This night, there was silence.

Suddenly, Tony noticed the darkness that surrounded him, he noticed that none of the lights were on. The only thing that brought some illumination to the room in which he stood was the pale light of the moon, shining through the large glass windows. The atmosphere was eerie, and the air seemed to grow colder by the second. "Hey, Jarvis! Is my AC malfunctioning again?" No reply. Was Jarvis having some kind of glitch, or was the AI playing tricks on him? Tony thought to himself that he should never have given his software a sense of humour equally as bad as his own.

"This isn't funny, Jarvis. I order you to resume activity this mo-"

He turned around, and immediately knew that he was not alone. There was someone standing in front of one of his windows, looking out at the bay. The semi-long, sleek raven hair, the green and black clothing, which, by the way, Tony found strangely attractive, was unmistakeable.

"Loki." Tony was immediately on the defensive, his eyes darting around the room to determine if he had anything to fight the god with. Apart from sofa cushions, which wouldn't do much good unless Loki agreed to a pillow fight, there was nothing. The billionaire was completely vulnerable, and as the raven-haired god turned around to face him, a nonchalant, yet emotionless, expression on his face, he felt an involuntary shiver go down his spine. The way Loki looked at him wasn't the usual 'I'll kill you, puny human', no, it was predatorial but there was something else to it – something strangely familiar to Tony.

"Stark." Loki's voice was smooth and treacherous as a silken viper, and the half-smile playing on his lips was not reassuring at all. The god of lies slowly stepped away from the window, his strides short and slow as he walked towards Tony.

"What the hell are you doing here?" A momentary flash of panic showed in Tony's eyes as he began to step away from Loki, his steps less sure than the asgardian's. He really wasn't in the mood to face his greatest enemy right now, and the usual, self-assured, confident Tony Stark wasn't ready with a snarky remark and a good punch. He didn't even get a proper answer to his question.

"Back in the day, my people would claim war prizes from the lands they conquered. This practise spread to most of the human tribes we came in contact with, and so they twisted it in their own way." Loki had backed Tony all the way to the wall, and the billionaire could back no further. Before he had a chance to make a run for it, the god slammed his hands against the wall on either side of Tony, and there was nowhere to run. He didn't really understand what Loki was saying – war prize?

"I defeated you in battle, Tony Stark, I doubt you'd ever forget that." Loki smirked as Tony looked away from him the moment he leaned closer. He could hear the Midgardian gritting his teeth with regret. He knew why – it had been one moment of distraction that had made the difference. Nonetheless, Loki had defeated Stark. And now he wanted his prize.

"You were my conquest, Stark. Now I want my prize." Before Tony had a chance to ask about what said prize was to be, Loki had answered his question. The god grasped Tony's chin and forced him to look up into those brilliant, emerald eyes. And then, much to Tony's shock, Loki kissed him. The kiss was forceful, primal, dominating, almost brutal. Tony pressed both hands against the Asgardian's chest, trying to push him away with all the strength he had, and though it was considerable for a human, it was not enough to even make the god budge. Loki released his lips and chuckled at his exertions, brushing them off like nothing. "You cannot fight me, Iron Man. It would be better if you simply gave yourself to me." Oh god, the way he said it, the silken voice, the dark tone, it was almost enough to convince Tony that he was right. Still, Tony Stark was nothing if not stubborn.

"No, Loki, I'll pay anything –"

"This is not about material worth, Stark. I will have you writhing beneath me, a memory to cherish for all my life. My worst enemy, begging for me, moaning my name with divine reverence." Loki smirked again when Tony groaned, a deep, throaty sound that could mean nothing but desire. Once again, the god claimed his lips, nibbling at his lower lip to make him open his mouth. Tony did just that, much to his own shock and surprise. This time, the kiss was full of need, pouring in from both sides. Their tongues battled for dominance, and though Tony gave up a good fight, he lost it. This, he both hated and loved. Loki, on the other hand, relished the way Tony only reluctantly, and much against his own will, moaned into the kiss, the way his beard prickled, his brow creased. This wasn't about love, in no way, it was all about pleasure, and conquest.

Tony broke the kiss in an involuntary, and embarrassingly loud, moan when Loki sneaked his leg in between his, letting his thigh grind against Tony's groin. When the motion was repeated, at the same time as the god began to nibble down his neck, the billionaire began to pant. Usually he was in charge, but this, this was different, this was – oh god, oh god, oh god. Loki had found the spot, -that- spot, right beneath his collarbone and Tony groaned, throwing his head back against the wall. He knew he was very aroused now, there was no way the god had missed it, and when one of Loki's hands began to rub against his erection, granting much-needed friction through the now very strained jeans, Tony almost shouted his name.

"Oh fuck, Lok-" He bit down on his lip, hard, to avoid doing exactly what the god wanted him to do. There was still some defiance left in Tony Stark. Loki smirked, his other hand joining the first now that he was somewhat sure that Tony wouldn't bolt the moment he was no longer enclosed within his arms. Tony forced himself to take a deep breath as his pants were unzipped, then discarded, and his boxers followed suit. Soon, he was completely naked, while the god was still fully clothed. Not fair.

"You seem… Overdressed." Tony managed to say, his voice strained as he struggled to keep from moaning. Loki looked down at him, one eyebrow nonchalantly raised. Then, to Tony's great surprise, he stripped. All the way to his bare skin, only his pants remaining. And suddenly, he was on his knees before his prey, and Tony could feel his manhood being enveloped in soft wetness that could only be Loki's mouth. It was all Tony could do to stay on his feet, his knees shaking as the god began to lick his shaft, bobbing his head up and down to pleasure him.

"Oh fuck, oh fuck, oh fuck." Tony practically chanted as Loki masterfully found all the right spots and all the right ways. He could feel pressure building in his groin, and desperately grasped Loki's hair, trying to get him to move away. "Fuck it, Loki, I'll come!" He groaned, but Loki only looked up at him with the closest thing he could come to a grin on his face, and continued. Before long, Tony was pushed off the edge, and he emptied himself into the god's mouth, almost shocked to feel him swallow. While he was still recovering, his breath quick and shallow and his heartbeat elevated, Loki stood up and promptly turned him around, so that he was facing the wall. Without warning, Tony felt a cold finger circling his hole, and he winced when Loki pushed the digit in. It was embarrassing to say, but in this respect, Tony Stark, infamous playboy billionaire, was a virgin. After a few strokes, his legs began to shake, as much in anticipation as a result of what Loki had just done to him.

"Loki, I can't.. Can't stand, please-" Tony winced again, but this time it wasn't in pain. It was pleasure. Somehow, Loki had fund a bundle of nerves, and the way he prodded it with his fingertip – right there, oh, god, fucking hell! Tony couldn't even think straight, and much less speak full sentences right in that breathless moment. Loki could, luckily, and though Tony couldn't help but let out a disappointed mewl when the god removed his finger, he guided Tony to the sofa in the room, white, like most of Tony's furniture in the mansion, and pushed him down upon it. Hovering above the man, he had the opportunity to apply pressure to all the right laces with his entire body, and so he did, while making Tony lift his legs and wrap them around his waist. He would have taken the avenger right then and there, but he knew that it would be too painful. He had felt how tight Stark was, how even the smallest ministrations made him react quite forcefully, and so he knew that he had to take his time. This time, he pressed two fingers into Tony, gently pumping them in and out for several minutes, all while the billionaire thrashed beneath him, whimpering and moaning. At some point, Stark came to wrap his arms around Loki's neck, though he did so gently, and the Asgardian allowed it.

However much he wanted to prepare Stark, Loki couldn't wait forever. He felt his own need grow, and thus, when he estimated that the intrusion wouldn't lead to excessive pain, he removed his fingers, much to Tony's disapproval, and took off his pants. Perched above the Midgardian, Loki caught his hazed gaze, and held it unblinkingly as he slowly pushed in. Tony winced, his hands began to claw at Loki's back, but he did not make a sound, save a gasp when the cold manhood was fully sheathed within him. Then Loki began thrusting, gently at first, and Tony couldn't keep himself quiet any longer.

"Loki, ah, Loki!" He breathed erratically at best now, and he was getting hard again, just from the stimulation of his prostate. The fact that this was his worst enemy didn't make this whole thing any less arousing. Loki, too, was beginning to lose control over himself, and first his fingertips, then his arms, then his torso and the rest of his body, became blue. Suddenly, Tony was held and penetrated by coldness, and the sudden chill within him went straight to his groin. Loki began to thrust harder, and faster, gripping Tony's shoulders to brace himself.

"Oh god, Loki, more, please, more!" Tony gasped, shouting the Asgardian's name, chanting it with divine reverence. This, as well as Tony clenching down, made Loki tense and, in one glorious, ecstatic moment, he spilled his own, cold, seed within his worst enemy, who took it into his warmth with a sudden, blinding orgasm of his own. Both men were quiet for a split second, tensing, arching, thrashing, and then they came crashing down with powerful shouts, and, from Tony, even something that sounded like a scream.

When, finally, he had calmed somewhat, although he was still panting, Tony spoke. "Loki, I…"

"Be quiet, Stark. You belong to me now, remember that when you lie with your Midgardian women." Loki suddenly withdrew himself, elegantly getting off the sofa before Tony had a chance to wrap his arms around him and stop him from moving away. "No, Loki, please – "

"Goodbye, Stark." With those words, completely ignoring Tony's pleads, Loki, with his clothes in his arms, disappeared. Tony swore loudly, trying to get off the sofa, but deciding against it when he felt how sore he already was. He would just have to deal with this in the morning, he thought. He drifted off just when Jarvis restarted, and the AI knew better than to interrupt his master's sleep.
