So, this is another fic based on a dream. I'm just cool like that.

Warnings/Disclaimer: ignores Loki's punishment on Asgard and skips to him wrecking chaos on the planet Earth for kicks and giggles without getting caught this time with all the Avengers that aren't mine, obviously going to be FrostIron, references to sexual elements and some dubious consent/enjoyment, angst sharing, a bit of language, and that's all I can think of. E&R!

Prologue: In Which Tony is an Idiot

He didn't know how it came to this.

Well, actually, no. That was a lie. He knew exactly how their little game started because getting thrown out of his own penthouse, of his own building, was just a tad infuriating, not to mention potentially lethal-not that he really expected to turn into a nasty mush of goo on the cement twenty stories down because he had planned preventive measures against it, in a way-so it was reasonable to expect some form of revenge. And, no, he so wasn't obsessing, thank you very much, ex-childhood-hero.

Yeah, so the product of his logical notobsession was revenge. And that was why he kicked Loki to his (not) doom the first chance he got. If nothing else, the split-second of fear (surprise) in his way too expressive eyes was worth it. Even if Loki somehow teleported the both of them to the roof of that same tower-still under reconstruction, thanks Hulk-that started it all and marched him-no, seriously, proper angry high knees and all-over to the edge, again, with no suit on and only the, admittedly, very firm grip on his collar.

"I do not think you grasp the severity of your situation, mortal," he drawled.

"No, no," Tony said hurriedly. "I do, bright eyes," Loki scowled at that, touchy as he was, and raised him higher in preparation to let him fall that much farther.

"See," he continued trying to explain himself better. "What's going to happen, is you're going to drop me and carry on your plan for world domination as an attempt to get daddy to love you-" Loki hissed, narrowing his eyes painfully, and Anthony got an uncomfortable reminder that they were dealing with a real-live Voldemort here. He decided to wrap it up. "But what will happen is that I somehow escape death-looking devilishly handsome while I do it like always-and aid in your plot's destruction so we can carry on this weird cycle of trying to kill each other by various ways of falling to our demise,"

The god suddenly got a peculiar gleam in those bright eyes of his and set him down with a sigh; but he did not let him go. "I grow tired of my so-called plots. Repetition bores me. The average mortals of your world bore me," They gleamed brighter, fixating on him. A sick pit started in the bottom of his stomach. "You do not,"

"And your point is?" he asked dryly ignoring his bad feelings, like always.

Loki chuckled faintly, unfurling his fingers with all the dextrous motion of a snake-and what was with the snake metaphors today? "I do not take kindly to boredom, Stark, as you well know," he grinned and his teeth were astoundingly white. "Let's play a game," And, really, god of mischief wants to play anything, you should run right out of there. He had the spidey-sense to prove it, too.

So what does Tony do?

"Just name the rules," he grinned back.

Of course.

They were going to play tag.

But it was a secret version of tag that had its own cool points system.

Like, 5 points for landing a 'tag', 10 for matching the previous tag, 50 for upping the stakes; say, instead of tapping your target on the shoulder, you plop a big fat one on the lips-oh, yes, things got sexual fast, how could they not? 15 points for tags that could take a lot of time times the number of minutes however long the tag is sustained without getting noticed by the Avengers or media. 100 points if the taged 'surrenders' or pulls away from the tag, but 50 points to him if he actually participates to the tag. Tags could only be completed while battling, though that was upended later by the ability to bring in additional rules at any time if both parties agree to the change. All tags were turn based, so time wisely. No blood or any other type of malicious and intentional injury was to occur at any time. Whoever gets caught in control at the time of the tag in question loses. And so on.

Simple and innocent, right?

He didn't expect to be drawn into it, in fact, he hated the game tag when he was a kid. But Loki was strangely compelling in his competitiveness and it infiltrated him by proxy easily. After all, he had a competitive nature just as eager to be challenged and a little more...open morality than a "superhero" should technically have. All in all, he should have known where this was going. Especially when he caught himself wishing for Loki to show up.
