A/N: This chapter really gets into the M rating. I kept it as clean as possible, but it's definitely an adult story.

Impersonating Evil

Loki stood on his balcony at sunrise Thursday morning. After his altercation with Theoric the night before, he hadn't slept; he spent the night trying to find a way to stop him. He looked towards Iwaldi's house, intent on seeing Sigyn despite both their fathers' wishes. He had to tell her what he'd heard Theoric say. He couldn't let her go in blind, there had to be some way to stop it, to keep her safe.

He stood there still as a statue watching her house, waiting for her to leave so he could get to her. Two hours went by before her sisters started leaving the house, one by one, until only Sigyn, Iwaldi, and one of her sisters remained. Finally, another hour later, the door opened and Sigyn came into view, arm in arm with her sister.

Loki straightened up, more alert now that he saw her. He watched her walk towards the market with her sister and was about to leave to find her, but Sigyn kept looking back over her shoulder. They went around the block from her house, then she and her sister doubled back, heading towards the forest.

"She's going to the meadow," he thought to himself. "Run. Go, she might not have much time. RUN!"

He burst out of his room, running down the hall and almost slamming into Thor and Fandral on their way to the banquet hall.

"Where is the fire, Brother?" Thor laughed.

Loki ignored him and ran full speed through the streets. He didn't care who saw him anymore. He had to get to Sigyn.

Fifteen minutes later, Loki arrived, out of breath and distressed. "I saw you...head into...the woods...from my balcony," he huffed, "you can't...marry Theoric...Sigyn, he's...going to...rape you."

Sigyn jumped up from the ground and wrapped her arms around him, burying her face in his chest. Lofn was with her, and she stood to her feet, a stunned look on her face.

"There's nothing either of you can do now," Lofn said. "Father has forbidden Sigyn from seeing you, so he'll just see it as a lie to postpone the wedding. And I take it you've had equally bad luck in the matter."

"I overheard Theoric last night, bragging about it to his whores. My father wouldn't hear it. He said I didn't have enough proof. Even with eyewitnesses, not enough proof," Loki sighed.

"Just be there tomorrow," Sigyn spoke up, "just be at the wedding. If I see you, it'll help me be strong. I'll just think of you when he..." she trailed off.

"No, damn it. I can't let her go through with this. I have to fix this."

"I would never hurt you like that!" he replied angrily, not mad at her, but at his lack of options. "I'll be there, I promise you."

"Sigyn, we can't stay much longer," Lofn said, "we've already lied to Father."

Loki leaned down and kissed Sigyn as Lofn pulled her away to leave. "Whether you can see me or not, I swear I'll be right by your side."

And with that, the sisters left the meadow, leaving Loki behind. He stood there in shock until she was long gone, then covered himself and made his way back towards his chambers. He changed his mind just outside his door and went to the Library instead; there was nothing in the books that he kept in his room, he had to find something older.

He spent the next four hours flipping through page after page, book after book, until he found the two spells he needed. He spent an hour perfecting the first one, then went off to try the second one on some of the guards. He had to have everything perfect before he went to deal with Theoric.

At sunset, he left the castle again, sneaking into Theoric's house unnoticed. He sat down on a chair in the corner and waited; the more time that passed, the angrier Loki became. He kept picturing Theoric hurting Sigyn, and his blood was boiling in his veins.

Hours later, Theoric drunkenly stumbled into his house. Loki was upon him as soon as he locked his door. Theoric's coordination and reaction time were diminished by his inebriated state, and Loki landed blow after blow, until Theoric was a bleeding mess on the floor. Loki stood over Theoric, as he peered up at him from the floor.

"You dared to threaten her safety, her innocence, right to my FACE?!" Loki yelled.

"She's not your problem," Theoric choked out through the blood in his mouth. "You're only making it worse for her. I'm going to break her." He laughed, "She belongs to me, and there's nothing you can do about it."

"Ah," Loki shook his finger at Theoric, "you see, that's where you're wrong." He knelt down next to Theoric, a purple glow coming from his hand as he pressed it against Theoric's forehead. "You're going to sleep right through the wedding. As ill as it makes me to subject myself to impersonating you, I'm out of options. I love her, and the mere thought of you violating any part of her existence makes me want to tear your limbs from your body. If you come near her again, I will make good on that threat. Now, sleep."

And with that, Theoric's head fell to the floor with a loud thump. Loki rolled his body underneath the bed and went through the house, making sure that all of the curtains were drawn shut on the windows. When he knew that nobody could see in, he sat at the table and rested his head on his hands. He thought of her as he drifted off to sleep.

Loki awoke to banging at the door. He jumped up and went to Theoric's bureau, finding his formal uniform and looking it over, memorizing it. He stood in front of the mirror and watched as his appearance changed to look like Theoric.

"Just a moment," he said in Theoric's voice, and smirked at himself.

"You've done it," he thought to himself, "now just keep the illusion up and go save her."

He checked on the real Theoric before opening the door and leaving for the castle. He was under the bed, snoring in a puddle of his own drool. Loki smirked at the sight.

He walked outside, locking the door from the inside before pulling it shut. The streets were full of people making their way up to the castle for the wedding.

Loki caught sight of Iwaldi and Freya ahead of him, arm in arm. Their daughters were walking just behind them; Sigyn had her head down. It made him so angry that her family wouldn't budge to ensure her safety and wellbeing; it would be over soon enough, though, and then she'd never have to see them again.

He watched them quickly hide her away in the dressing room and leave her alone. He ducked behind a column near the door to hide and sent a projection of himself into the room to check on her. She was edging slowly towards the balcony.

"I know what you're thinking," Loki called out to her, "and if you jump, I'm jumping after you."

She spun around to look at him. "Are you really here?"

"No, it's a projection. I'm not far though. I can't stay long, your family will be in here any moment. Just remember what I told you, just because you don't see me, it doesn't mean I'm not here." And with that he pulled the projection back. He made his way up to the altar. The fact that he was tricking all of Asgard for her made him nervous; one slip up could ruin everything.

He took his place at the altar. His mother was looking around with an upset look on her face, probably looking for him. Sigyn's sisters began walking down the aisle. He hated that he couldn't let her in on the fact that it was him standing here, not Theoric.

He watched the door to the dressing room as her sisters exited, until he saw her. She looked like she was about to make a run for it. He projected enough energy back to her to talk to her one more time. She just needed to stay, everything would work out if she just stayed. "Breathe. I'm here, love. I promise you it will be alright. Just breathe."

He saw her head whip around behind her, then she looked forward again and he could tell that she was crying again. Her father met her at the door and they started making their way up to the altar. When she was almost up to him, he saw that she was panicking, looking at his family, trying to find him.

Loki stepped down and Iwaldi passed her hand to him, then went to take a seat. She looked up at him, and he grinned back at her, leading her back up to Odin. He hated that she saw Theoric and not him.

"It's almost done," he thought.

Odin began reading their vows, looking at Loki. "Repeat after me. I vow to be faithful to my bride, to keep watch over her, and to honor this marriage, and this marriage alone, until the end of time itself."

Sigyn scanned the rows of people in attendance.

"She's still trying to find me. I hope she doesn't think that I abandoned her."

"Sigyn," Odin's voice boomed, "repeat after me. I vow to be faithful to my groom, to keep watch over him, and to honor this marriage, and this marriage alone, until the end of time itself." She did as she was told. Odin turned back to Loki. "I now pronounce you husband and wife, you may kiss your bride."

He leaned in to kiss her; she closed her eyes tight. "I did it. Enough of this lie, now." His lips touched hers. A glow washed over him and Sigyn as he changed back to looking like himself. People around them started yelling.

"What have you done, boy?!" Odin shouted. She opened her eyes. "Loki! I warned you against meddling with this wedding. Do you not dare heed the orders of your father, of your king?! Foolish child." Odin turned to face Sigyn. "Sigyn, I apologize, my dear. This marriage will be annulled immediately."

Loki opened his mouth to argue, but Odin shouted at him. "Do not try my patience right now! I will deal with you after I fix the problems you have created."

"No, Allfather," Sigyn spoke up, "I accept this marriage. I do not wish for it to be annulled." Loki smiled at her.

Odin seemed to be deep in thought before he spoke again. "Then, for your commitment to these unforeseen circumstances, I hereby deem you the Goddess of Fidelity and Bonds."

Before anyone else could object, Loki grabbed Sigyn's hand and they both vanished from the throne room, reappearing within his chambers.

"Is this real, or have I just fainted at the altar?" She was still a shaking nervous wreck.

"I told you that I would keep you safe," he wrapped his arms around her, "now we belong to nobody but each other. My wife." Those two words echoed in her head. "Now, though, you've been through too much, emotionally. You're still shaking." He sat her down on his bed. "Rest here a moment, I'll run us a hot bath. You're safe now, Sigyn."

Loki walked off into his bathroom and lit two candles as he filled the bathtub. After he turned the water off, he went back out to Sigyn. She stood on his balcony staring out at the view and didn't hear Loki come up behind her.

"Are you alright?" She nodded silently. "Come inside, the bath will help you relax." He took her hand and led her back inside. Loki turned and kissed her, soft and slow, before she turned away from him and pulled her hair over one shoulder.

"Can you untie my dress?" Chills shot down his spine as he loosened the ribbons that crisscrossed down her back. His hands were shaking and it was hard for him to breathe. Once it was loose enough, she pushed her clothing down at her feet, and she was left nude with her back to him.

He took in every inch of her body, every curve. She was perfect. He followed her with his eyes as she crossed the room to the bathroom. She turned back to him in the doorway and smiled. "Are you going to join me, husband?"

He blinked and nodded. "I'd be stupid not to."

He heard her getting into the water, and that jarred him back to reality. He pulled off his shirt and kicked his boots off as he crossed the room. Her breathing became heavier as she looked up at him standing in the doorway.

He finished undressing and watched her reaction; when she saw him fully naked her eyes went wide. He couldn't keep the grin off of his face when she looked up at him. She blushed as he climbed into the bath with her. Once he sat down, she laid back against his chest and rested her head against his left shoulder. They laid together for a few minutes, still and silent.

"Do you feel any better?"

"A bit, but it's still sinking in. I expected to be lost and broken right now."

"I promised you that I'd fix it. I wasn't about to let him hurt you like that."

"Loki," she hesitated, "what did you do to Theoric? Is he alive?"

"I wanted to kill him. But he's only sleeping. He'll wake up later tonight. If he wasn't on my father's guard, I probably would have beat him to death." He kissed her shoulder. "Let's not worry about him anymore. It's just us tonight, and I'll keep our doors locked for as long as you want."

She turned around to face him. The closeness and intimacy of the situation made it impossible for him not to be turned on by her. She looked down at his body when she realized it, and her eyes were wide when she looked back up at him. He laughed at her reaction; her innocence was adorable.

Before he realized what was happening, she reached under the water and touched him. He gripped the sides of the tub and his head fell back as he closed his eyes. She kept one hand on him as she started kissing his neck. He couldn't believe that she had made the first move; it felt like electricity all throughout his body.

"S-Sigyn," he choked out. He was gripping the sides of the bathtub so hard that his knuckles were white. Her free hand found its way into his hair as she moved up and kissed his lips; he struggled to regain his composure as her taste and smell overloaded his senses. He couldn't even form a single thought. He moaned into her mouth as his legs went rigid and he climaxed.

As soon as she let go of him and moved away from him in the water, he relaxed and rubbed his face with his hands. His mouth was dry and everything felt numb. He brought his knees up above the water.

"I can't believe you just did that," he finally managed. "That was...there are no words. I can't even think straight."

"Loki," she whispered, "I want you so badly. Can we go to bed?" His head was spinning. Nobody had ever had this effect on him. He needed her.

With all the effort he had put into stopping Theoric from marrying her, he never even really thought about the fact that he'd have her alone after the wedding. Now, though, she was right in front of him, nude in his bathtub and begging him to take her innocence.

"Loki? Are you alright?" She moved back over to him and touched his chest. He jolted at her touch and sat up, looking in her startled eyes. She was breathing so heavy; drops of water were beading up and rolling down her body as she knelt in front of him.

He couldn't stand it anymore; he stood up and lifted Sigyn up into his arms and carried her out to his bed. She stretched out on her back and he froze again. The look in her eyes when she looked at him was driving him mad; nobody ever looked at him like that before, like he was the only thing that mattered. His hands were shaking again.

Sigyn sat up and reached out and grabbed his hands. "I'm nervous, too, Loki. But I trust you. Don't hold back."

He shook his head. "I don't deserve you."

She pulled him down onto the bed on top of her. "Whether you do or not, I'm your wife now." Her hands went up into his hair again, and she wrapped her legs around him. "Claim me, Loki."

He hesitated. "If it hurts, promise you'll tell me." She nodded. He adjusted his weight on top of her and thrust into her, then stopped to let her get used to the feeling. She cried out as he broke through her virginity and her eyes teared; he kissed her cheeks over and over. "I'm sorry, love. I'm so sorry."

"It's alright, Loki," she finally exhaled. "Keep going." He followed her lead, changing the pace whenever she told him to. He couldn't take his eyes off of her face. Her sighs quickly turned to whimpers. When he realized she was close, he reached one arm underneath her and gently lifted her back off of the bed; he had been on the edge for minutes but he held back so that they finished together. Sigyn started rolling her hips back against him to meet each thrust. She dragged her fingernails across his back as her moans got louder until they both collapsed, exhausted and sweating.

"I love you, Sigyn. So much more than you'll ever know." They didn't move, just laid there in each other's arms, catching their breath until they both fell asleep.
