18 years later

It had been a long, whirlwind of fifteen years. Tony had never felt so much like he was in a race car going too fast around a track as he had these past eighteen years. Equal parts thrilling and 'what the hell did I get into'.

Asta had expressed recent interest in going to Midgard and learning the science of her father's world. She was learning Loki's magic well and been trained by Sif and her Uncle Thor in the warrior arts. She was too much like Loki and gave Tony more grey hairs then he'd ever seen in his life. How did an immortal get grey hair? By having a hellion for a child, that's how. And one for a husband. Each day was a lesson in why exactly he'd never gotten married until meeting Loki and yet he never once regretted it.

Pepper was a brilliant CEO and the Stark Company hadn't foundered. Tony felt like he was going to gift it to Asta to run when Pepper was gone and after she had the knowledge to run it. She was never going to be on the throne of this planet after all, might as well give her something to preoccupy herself or else he pictured many times getting her out of trouble. More then had already happened.

They had visited over the years of course. Uncle Steve doted on Asta and she expressed that the blonde captain was going to have to marry her when she got older many times. Tony hoped it was a childish fancy. When he'd been a kid he'd wanted to marry Madonna so he waited for it to pass. He didn't want his best friend as a son-in-law. Not that Steve had ever expressed an interest but Tony knew well that you could never know what happens in life.

Loki walked into the large chambers the small family shared in the golden palace of Asgard. It had taken a while for Tony to get use to not having tvs, or cars, and he overindulged himself everytime he and Thor went back to earth to help the Avengers, or just when they were in need of a vacation or to escape his in-laws. He was holding their second child, three month old Leifr. Their only son. Tony smiled at the thought of his four children. Five years after Asta had been born, Tony woke up one morning to find Loki as a woman again, and not voluntarily. He hadn't assumed that form at all since the day they had gotten married and Tony'd made him change back. Odin certainly hadn't be enthused at the thought that the married couple actually had sex, despite doting on Asta, he preferred to think of the marriage as his son's flight of fancy. Frigga had just expressed her knowing congratulations.

The twin girls born were Signy and Tofa. Both were as unmagical as Tony and Thor, the only ones of any of Loki's children to not even have an ounce of it. What they lacked in magic they more then made up for in intelligence. By three months they'd already been walking and at eight months been talking in sentences. They'd devoured every book in the palace of Asgard and had managed to sneak off past Heimdall twice to visit earth university's. How was anyone's guess, considering they were thirteen years old and couldn't cloak themselves like Loki.

Tony couldn't even think of what trouble and headaches Leifr was going to be causing him soon. He smiled, taking the baby when Loki handed him to him and kissed his husband. He finally understood a father's greatest creation.
