30 days frostiron challenge

So hello again!
I know I should be posting the sequel to Around the world, but I'm in a big writers block and just can't see how I will continue it. So, to help I have decided to do this, to get my fantazie to start working again. I have to say beforehand that this is not Beta read and apologize now for the misspellings and grammer misstakes that is about to come. I hope you can just over see it.
Anyway... These stories will be linked together so it's like one big story. Thats why the background part so that I don't need to tell it on day one. And there will be MPREG at the end and if you don't like that you can just stop reading after day twenty seven.
I hope you will like it and I will try to update dayly if not every other day since I don't need to send this to a beta and I don't really have anything to do then watch my dog. So you will get Background today and maybe day one later if not tomorrow.

Background:
After the whole taking over Midgard thing, Loki was sent back to Asgard and got his punishment. It was not what Loki had thought it would be. He thought it would be torture, imprisoned and locked away forever. But that was not what Odin had in plan for his son. Loki was sent back with Thor to Midgard with a minimum amount of magic in the wizard. He was to live as humanly as possible and only allowed to use his magic if he was to save another human. Loki thought this punishment was even worse than the once he had prepared himself for. After long discussions with the group of misfits, they agreed on letting Loki stay in the Stark tower. Hawkeye was the one who really had great issues with Loki being allowed to move relatively freely under the watchful eyes of the Avengers. So Fury let him and Natasha go on missions together to cool him down. But the others didn't seem to have such big problems with the gods living with them. Steve mostly trained and Thor joined him, Bruce was mostly locked up in his lab and Stark… Well, he seemed to be the only one that really had no problems at all with having the tall raven-haired god around. In fact, he was the one spending most time with Loki. The genius had recently broken up with Pepper because the whole Iron Man thing was too much for her to handle and they decided to just continue as best friends. Loki tried to keep to himself in the beginning, but the way the genius teased and joked with him, made him come out of his shell a little and let Stark be around him. He was the brightest one of them all and could match Loki's quick mouth and brain. But what was to come, no one saw coming at all.
