Steve had no recollection of what happened the night before, but quite frankly, he wasn't sure if he wanted to find out.
Waking up, he'd found himself naked except for a single sock, drooling on one of those fancy foreign pillows in the mansion's living room. He managed to roll himself around and caught an eyeful of Thor's peanut butter-smeared-
Steve quickly rolled the other way. Not that it made it any better since then he was presented with the sight of passed out Clint with Thor's helmet, Tony right under the archer, and...was that Bruce? When had he come in and why was the room still standing?
"Stop moving around," commanded a voice by his thigh. Steve flinched in alarm as he looked down to see a mess of red curls and a hand creep up his leg. He blushed, as if the sights of all his male teammates in various states of nakedness was nothing compared to seeing the Black Widow's face so close to his privates. And she wasn't even moving away!
Alright, maybe he kind of wanted to know why Natasha was fondling to his leg, but otherwise, Steve was pretty sure he didn't want to know.
He was also equally sure that he should be as far away from the living room as possible the moment all the guys woke up, especially Bruce. If the amounts of cans and bottles littering the ruins of expensive furniture was any indication, they were all due for some very unpleasant hangovers.
Much later, after Tony had Pepper call a few people to reconstruct half the mansion, order some new furniture, and call in Betty Ross to calm Bruce down, Steve and the rest of the Avengers found themselves in the kitchen.
He was pretty sure none of them wanted to be there, but Clint, while hunting down another icepack for his back, had found a clue about what happened the previous night.
The said clue, nearly sent Bruce into another Hulk fit. It also sent Tony into a rage, which in turn set Thor off since Loki might be one of the most horrible supervillains around, but he was still Thor's brother.
Steve sighed and looked at the note again while trying to ignore the awkward tension he and Natasha seemed to be creating. Clint was still there, rooting around for an icepack.
All of that had happened a year ago and now all of them were standing rather awkwardly in a really nice penthouse, staring at Loki with a dark-haired, green-eyed baby in his arms.
