Summary: "I'm married-" she whispered, "-to your brother." Sif is stuck in a loveless, dull marriage to Thor and Loki takes it upon himself to make her feel better. What starts with simple training-sessions soon lead to something more.

AN: I have never thought much about Thor/Sif or Loki/Sif, but I decided to give it a try. This is what happened. It will be a short story, but I do hope many will enjoy it. I actually have no idea how popular these pairings are… The title comes from the song 'Wildest Moments' by Jessie Ware (I don't own anything!) which partially inspired this fic.

Please let me know what you think. Any and all feedback is welcome.

Chapter 1

The entire hall was silent. Everyone's gazes were on Thor and Sif standing before the Allfather, their hands clasped together and radiant smiles plastered on their faces. They looked nothing less than perfect. Sif looked stunning in a bronze dress which seemed to embrace her small, muscled yet feminine body. It accented her slim waistline and her broad hips. A red bracelet accented her red lips and a golden necklace made her dark brown eyes look like dark diamonds. Her long raven hair fell across her back. It wasn't often that she wore her hair loose, but it definitely suited her.

Thor, as prince and heir of Asgard, looked regal and imposing. He wore his battle outfit which had been polished by at least six different servants. His red cloak looked spotless and his hair looked more golden than ever. He appeared a proper, strong and worthy son of Odin. When his eyes connected with those of Sif, he flashed her a brilliant smile.

The image was romantic and Loki wished he could find something wrong with it. However, he had to admit that Thor and Sif looked perfect for each other. They were both warriors, both fierce and intelligent. There was not a person in this realm that doubted the success of their union. Even Odin himself looked rather pleased with the event.

When the king spoke, his deep voice echoed through the hall and held a hint of contentment.

"Then from this day onwards, Thor Odinson and Sif Thrudsdaughter are united as one. May their bond be ever so strong and blessed."

Thor leaned forward and planted an almost shy kiss on Sif's lips. The entire hall began to applaud and cheer. Loki recognized the voices of Volstagg and Fandral. Hogunn restrained himself to clapping while Frigga – who stood at his left side - appeared too overcome to do anything. Loki reached for her hand and suddenly found himself in her arms.

"Mother," he said, feeling his face flush. He did not want to entire court and other people see him I his mother's arms, but he knew Frigga cared nothing about that. "Why are you crying?"

"These are tears of joy," Frigga laughed, letting him go, but keeping hold of his hands, "I am happy, Loki."

"So am I," he replied with a smile.

It had never been a surprise to find out Thor and Sif were to be married, but Loki had always been…infatuated with Sif. There was something…different about her. She was beautiful – one of the most beautiful women in this realm –she was passionate and highly intelligent. She had never put up with any of his schemes and tricks and he liked her for that. You always knew what to expect with her.

Still, Loki was happy to see his brother smiling and laughing like that. He was clearly elated and there was not a man around who wasn't secretly jealous. He even suspected Fandral was jealous. The dashing warrior – Loki shuddered at the nickname – could get any woman, but he had never gotten Sif. It was yet another reason why Loki admired her so.

The hall grew emptier as people began to leave and Loki let his gaze slide around. There would be a great feast tonight and the people were already calling it the feast of the century. After all, it didn't happen often that the heir to the throne found himself a future queen. But Loki had never been one for parties, not those thrown by Thor anyway. There was too much ale and too much drunkenness. He suspected tonight would be even worse.

Before the newly married couple disappeared for a few hours, Loki caught up with them. He was pleasantly surprised to find that his brother instantly had all of his attention on him.

"Brother!" Thor roared, spreading his arms wide before pulling Loki into a crushing hug. Honestly, people always forgot Loki did not like physical contact, let alone hugs. "Meet my wife."

Loki rolled his eyes.

"I do know Sif, brother," he said though his voice betrayed nothing but amusement, "we have been friends since childhood. I only came to congratulate the both of you. The whole of Asgard was present in this very hall and all their eyes were fixed on you."

Thor laughed whole-heartedly and said, "And I have not forgotten any of my lines."

"Thank the Gods for that," Sif joined in.

She wanted to fold her hands before her stomach, but Loki swiftly caught her right hand into his own. He planted a sweet kiss on the back of her hand. It was an innocent gesture, but Loki liked the way her hand felt into his own. It was soft and small.

"You look very beautiful, Sif," he told her and he enjoyed watching her cheeks turn pink, "every women in Asgard is currently envious. I would watch out tonight." He winked at her and Sif chuckled. "Enjoy your day, you deserve it."

"And now…" Thor's eyes narrowed almost mischievously, something he had learned from Loki many years ago. "Now it is your turn, brother, when will we be introduced to the woman that stole your heart?"

"I'm afraid you're going to have to wait a bit longer," Loki grinned.

"Well, I'm sure she'll be lovely," Sif chirped, "and as cunning as you."

"Surely you mean intelligent."

"No, Loki, I definitely mean cunning as in devious, canny, crafty, sly-"

"I got your point," Loki interjected.

Sif burst into laughter and Thor joined her.

"Enjoy your evening," Loki said on a more serious note, "and I wish you many, many happy years."

Both Sif and Thor placed a fist over their hearts and bowed their heads.

"Thank you, brother."

A few years later

~ o ~

Loki was deep in thought while walking through the hallways of the palace. Many things were happening in the neighboring realms which disturbed him. It had been while since tensions had risen like this. Jotunheim was threatening with war against Asgard – as usual – and Vanaheim was threatening to attack Alfheim. On top of that, Midgard was ripping itself apart by a war that spread across the entire realm for the second time.

It was only when he heard the soft cries of an infant that he stopped dead in tracks. He wasn't used to hearing the cries of a small child, certainly not those of his niece. After all, there hadn't been a baby present in the palace since he and Thor had been infants, with the exception of guests who had brought along their children. Loki had never liked those times. He much preferred quiet times.

Slowly – and carefully – he approached the chambers that belonged to Thor and Sif. He wasn't sure what to expect, but when he quietly pushed open the doors, he found a sight that touched something deep within him. It was a sad sight, a pensive and slightly melancholic one. Loki had not expected this.

He found Sif standing before the cradle of her daughter, her arms hanging lifelessly next to her body and her shoulders hung forward. Her hair was tied together in a messy bun - something she normally didn't do – and her long, golden dress had a few stains. She appeared to be staring at the twisting and crying form of her child. Frida's little face was red and wet with tears. Loki wasn't sure what it all meant, but he only knew he wanted to make the nasty sound end.

Uncaring of the consequences, he walked inside and scooped the child up into his arms before gently rocking her. Frida's hard, red face softened until eventually her cries stopped. When Loki looked up, he found a stunned and embarrassed Sif staring at him. Her eyes stood wide and her lips were slightly parted. Even if she looked like a complete mess, he still found her beautiful.

A few moments of silence passed before Sif brought her hands to her face. Loki wasn't sure what was happening at first until he heard sobs come through her thin, pale fingers. He had never seen Sif cry before. She was a warrior woman; she was hard on the outside and on the inside. She didn't show any emotions otherwise her already frail position as a warrior was compromised. But there she stood, weeping like a lost child.

Loki had absolutely no idea what he should do. Had he done something to upset her? Perhaps he shouldn't have entered in the first place. He was almost completely certain Sif wanted to be alone right now. Maybe he had disturbed her moment with her daughter? It made little sense since he'd found Frida crying, but he simply couldn't think of anything else.

"I am so sorry," Sif suddenly uttered. She angrily wiped away her tears and clenched her hands into fists. She was starting to appear like her normal self again. There were still soft and pained edges to her, however, and she was clearly aware of them. "I am sorry for crying like this in front of you."

Loki opened his mouth to speak, but he found that he had nothing to say. Actually, he had a lot to say – he had always been a master with words - but seeing Sif so troubled and overcome silenced him momentarily. Apparently, there was something very obvious in his eyes because Sif lowered her gaze, looking ashamed.

"I normally don't let her cry like that," she said while pushing a few strands of hair behind her ears, "you must think I am horrible mother."

The way she had spoken those words unsettled Loki. Sif had said them so delicately that he knew she meant them. He had to make her believe otherwise even though he wasn't sure why he bothered. He should not be consoling her. Was that not Thor's task? Where was his brother anyway?

Loki shook those thoughts away and decided he needed to focus on his sister-in-law.

"I don't think you are a terrible mother," he said.

He looked down at the sleeping child in his arms. Frida looked peaceful at the moment and Loki gently stroked her soft baby-skin. She was a very pretty baby and Loki knew she was meant for greatness. One day, she would rule this very realm as a beautiful and regal queen. She was named after a beautiful and regal queen – his own mother Frigga – so it was only fitting.

"Where are your servants?"

Sif shrugged and hugged her own body. It was a small gesture but it had Loki's attention again. This was not something Sif did. It almost seemed as if she craved something. Contact? A listening ear? Again Loki could not help but wonder where his brother was.

"Thor doesn't want us to have many servants," Sif said callously, "he feels they are introducers to our privacy and he does not want our daughter to be raised by them."

Loki arched an eyebrow. That was the most ridiculous thing he had heard in a long time. It was not uncommon for children of royalty to be raised at least partially by servants or governesses. He and Thor had been raised by two different women! One was called Etta, a lovely old Asgardian woman with a penchant for baking and the other had been called Amma who had still been very young when she came to court to raise the princelings.

"And where is Thor?"

Sif huffed angrily while crossing her arms before her chest. She was starting to look and act like the Sif Loki knew and liked.

"He has gone hunting with the Warriors Three," she replied coldly, "he is never home."

There had been a time when Thor and Sif had been inseparable. That time was long gone it appeared. Their marriage had begun very promising and even though the people of Asgard still firmly believed Thor and Sif had one of the strongest marriages in Asgard, Loki and other inside royalties knew better. It had taken them ten years to produce an heir! Somehow, Sif and Thor did not work together that well, not when it came to domestic affairs.

It shouldn't have surprised Loki. Thor and Sif were both warriors and they both demanded a lot of freedom. Marriage had tied them down and they felt like suffocating. Loki didn't think they cheated on each other; they simply…avoided each other whenever possible. But now they had a child and spending time together as a family was required. Too bad they would never be a family by the looks of it. Loki sighed when gazing at his niece. She would never have a truly happy family.

"I need fresh air," Sif said, rubbing a hand over her tired face, "I need a moment away from these damned chambers. I need… By the Gods I miss everything so much, Loki."

Loki wasn't used to Sif confiding in him like this. They talked often, but never about sensitive things.

"I miss going out on adventures," Sif continued, her voice rising with joyful memories, "I miss the tension and the danger. I miss spending them with the Warriors Three and I miss laughing with them and about them! I miss… I miss training with my friends. I miss having a tight body and being the girl every man dreams about, but now look at me."

Sif lowered her gaze and sighed heavily.

"You're still beautiful," Loki said without thinking, "I've always found you incredibly beautiful."

Sif smiled thankfully.

"You're the first man to call me beautiful in a very long time."

An idea came to Loki at that moment, but he wasn't sure whether it was a good one. Still, he felt he had to do something about the situation and he wanted to make Sif feel better about herself. He didn't even know why. When they had been children, they couldn't really stand each other. Then Loki had cut off her hair and they had become enemies. Over the years, however, they had grown more accepting of one another and eventually they became friends. Their friendship had always been very platonic, but that had changed now. It had all changed the day Thor and Sif had become engaged.

"I'll call my servants," Loki said. Carefully he placed Frida back into her cradle. The girl's face tightened for a second, but Loki placed a caring and comforting hand on her little chest. She visibly relaxed and slept on. "They will care for your girl and we can go train."

Sif looked extremely skeptical and her muscles tightened. She looked as if Loki was playing one large scheme with her and she clearly did not appreciate.

"Come on," he urged, "you miss training and I am offering to spar with you."

"You've never sparred," Sif countered.

"Indeed I have not," Loki admitted, grinning, "but you can teach me. I dare you defeat me in battle if I am allowed to use magic."

"You always cheat," Sif argued, but she had regained lightness to her voice and appearances. Her body relaxed, but she straightened her back. "All right. Give me thirty minutes and I shall meet you on the training grounds."

Loki was looking forward to it.

AN: So what do you think of the introduction?
