Chapter 1: A Spark
It started out with a momentary lapse in judgment, a rush of post-battle adrenaline, and just a little too much alcohol.
Tony Stark had stumbled into his bedroom just after midnight and immediately come face-to-face with the God of Mischief himself. Before he had a chance to process what was happening, Tony found himself pressed against the wall, Loki's lips fiercely attacking his own. Slender hands held his arms, pinning him against the wall, and as soon as Tony regained control of himself, he fought back, fighting Loki for dominance. His hands tangled in the god's hair, yanking experimentally, and he smirked at Loki's responding moan of pleasure. His focus moved downwards, working at removing his armor. Loki broke the kiss for a brief moment, flicking his hand, and suddenly they were both naked.
Tony didn't have time to consider this before Loki's mouth was on him again, tangling their tongues together. He fought back a moan and instead dug his nails into Loki's lean shoulders. Loki arched into his touch and grabbed Tony, pulling him closer and shuffling towards the bed.
The night passed by in a whirlwind, both of them ravishing each other and fighting for dominance, for the opportunity to make the other submit to his will. Loki overpowered Tony, teasing him with that slick tongue over his cock; Tony fought back, bending Loki over the edge of the bed and threatening to fuck him senseless, nearly succeeding. Several hours after Loki's first appearance, the two were spent, and they collapsed back on Tony's bed, panting and covered with sweat and come.
Loki said nothing. He looked over at Tony, his breathing growing steady. He studied the other man, his expression measured. Tony met his eyes, not daring to speak.
Loki stared at Tony for a moment, when suddenly, he cupped his chin in his hand and kissed him. It wasn't rough or heavy like before. It was…soft, Tony realized. Almost sweet. He wasn't sure what to make of it.
Loki pulled away and looked back up at the ceiling. Tony avoided his gaze. He realized that he didn't want to ask what that was about.
There was a soft rustle of fabric, and when Tony looked to his side, Loki was gone.
