He ought to have known that he wouldn’t have forever with her, that even a powerful spirit such as herself would be snuffed out when the time came. The Norns held no court, no laws save their own, and offered no explanations as to why it was what they did. After Natalia and he had left the forest they’d traveled the world, gone as far as Natalia had ever been and then surpassed it. He’d never met Clint, the pair of them not having need. Everything they wished for was in their grasp, Loki’s magic fully at his disposal. Every single whim of hers was catered to, and Loki all the happier for it. Every evening was spent in each other’s arms, and every day the world unfolded for them, however it is they wanted it to.

But when he’d come back one evening to the small, abandoned palace he’d commandeered near the edge of England she’d not responded when he’d called out to her. It had forced him to hasten his steps, to chase shadows and bloodstains from room to room until finally finding her, choking on her own blood, in their bed. He’d howled and cradled her in his arms, cutting his own flesh in an offering to the Norns to bring her back--but nothing had happened. He buried her near her favorite garden just by the East, so she could watch the sunrise every morning as she had when they’d been together, and then took off to slaughter every and anyone who’d had a hand in her demise.

--

Some hundred years later, top hat covering his newly blackened curls, he was stopped dead in his tracks by a woman on the other side of the street. He’d seen red hair before, having traveled in Natalia’s absence, but there, amidst the stench of London smog and the burning lamps on the streets, she burned in front of him. Nevermind that she already had a man on her arm, his black hair much like Loki’s own, and nevermind that he doubted she had any idea who he was, he surged across the street the first chance he got.

“Pardon me, madam,” he said quickly, catching her shoulder with his own as they passed in the streets. There was a flash of displeasure in the eyes of the man, but Natalia’s green eyes were bright as she looked up through her lashes at him.

“Not a problem, sir,” she assured him with an easy smile. “I didn’t see you there.”

“I must say, if it’s not too forward,” Loki pressed even as the other man at her side started to try and tug her away. “Your hair is the most extraordinary shade of red. Did your mother give it to you?”

It made her laugh, nodding her head quickly. “She did.”

“How very thoughtful of her. I’m Loki, Loki Laufeyson.” His hand extended but his gaze never left hers, searching for some shred of recognition. Something. Anything. He was desperate for the slightest of hints that she knew who he was. And there was, making his stomach flip with excitement as her lips widened in a smile that lit up her whole face.

“Like the mythology? Wonderful, Sif here has the same fortune of being named after a deity.” She motioned to the man at her side, whose brown gaze Loki now recognized. The corners of his eyes crinkled in interest. Huh.

“Sif? Wasn’t that a goddess?”

Sif’s gaze hardened, his lips pressed so tightly that the corners of his mouth were white with displeasure. “I had an interesting mother. Better, I suppose, to be named after a warrior goddess than to be named after a trickster fool who ends up destroying the world.” His words were biting, his tongue as sharp as the blade Loki had known Sif to wield as a shieldmaiden. Curious that she’d changed her form, yet kept the name. Just what was she hoping to gain by changing herself into a man?

Still, Loki wasn’t called Silvertongued for nothing. It hardly took him half an hour to charm his way back to their home, Natasha, as she was called now, winking as she’d invited him. His mouth had gone dry, his pulse jumping into his throat at the invitation, and the walk took decades before they arrived at Sif’s manor. It was grand, he’d admit that, and as he was led inside by the male counterpart of the woman he’d once known he grinned to catch sight of paintings of women in battle, others of retelling of the same myths that had been told about them. He’d been there to influence one or two of them. With a quick batting of her lashes, Natasha excused herself to go get more comfortable, leaving the pair of men to speak in Sif’s parlor.

The door had hardly shut when Sif stared at Loki, his eyes narrowing. “You are absolutely ridiculous. What in the Hel do you think you’re doing?”

“Courting a lovely lady,” Loki shot back. “I’d never have thought you’d ever give up your body.” He wouldn't be able to understand why she had; she'd been beautiful, still was in her own way. He might've been a liar, but he'd never deny that.

“Yes, well you aren’t the only one who favors a switch up every so often.” Sif rolled his eyes. “Besides, it’s not as though I can pursue my own interests as a woman in this era.” Loki would’ve sworn, for half a moment, that it was the same goddess he’d known before, high cheekbones and withering glare and all. “Why did you pick Natasha, anyway? There’s always a reason with you--And I’m not leaving her, before you say anything.”

All pretense and smiles aside, Loki’s lips twisted into a scowl. “I lost her once before. I’m not going to do it again.”

“You ought to have taken better care of her,” Sif said, and his voice went darker than Loki had ever heard it go before. Loki’s own lips turned upwards in a snarl, teeth bared as his fist grabbed hold of Sif’s front and pulled him up close. He wasn’t fucking around anymore, his anger lashing out at the man in his grip enough to rip the glamor from his body and reveal the same goddess that he’d grown up with, who laughed at Thor’s quips and retaliated when Loki grew too comfortable with his mischief. She glowered, gripping his wrist in her own and twisting it hard enough to force him to release her, dropping back to her feet before the glamor replaced itself over her frame. The newly made male Sif dug his arm against Loki’s throat, backing him up against the wall.

Sif spat: “Don’t touch me again” as his eyes narrowed and the pressure on Loki’s larynx increased, and Loki simply stood still, his toes digging into the carpet, refusing to look away.

“Then don’t you insinuate I didn’t do enough. You don’t know a damn thing.”

Before Sif could say anything else, the sound of a throat being cleared forced them apart, Sif dropping Loki immediately. Loki rubbed his throat, muscles aching. Natasha stood in the doorway, one of her eyebrows arched as her arms folded just under her breasts, pressing them upwards even in the corset she’d undressed to.

“I was going to invite the pair of you up into my room, but if you’d rather have a pissing contest out here I’ll bid you both a pleasant evening.”

Her presence was more than enough to make them both go silent, Loki’s eyes widening as his stomach flopped, and Sif’s tongue darted out to flick against his bottom lip, his pupils blown. Any other time and Loki might’ve filleted a man where he stood for staring at Natasha in that way, but as it was currently he didn’t have the bargaining rights to demand her for himself. Sharing wasn’t his favorite of options, but he’d deal with it at least until he could convince her to be his completely. It was a small mercy, he supposed, that at least it was only sharing with Sif. It could've been far worse, all things considered.

“Is there going to be a problem, boys?” Natasha asked, her head cocked to the side, green eyes turning from Sif to Loki, then back to Sif. Both men were keen to shake their head, assure her that there absolutely wouldn’t be a problem, to which she offered them a crooked smirk and beckoned them to follow her with a crick of her finger. To say that they were chasing after her was a grievous understatement.

Her room was dripping with excess, whatever it was that Sif did obviously paying well enough to afford Natasha such lavish furnishings, and it was only after the door had closed that Sif pounced on Natasha, claiming her mouth for his own. Loki took to skimming his fingertips across her shoulders, loving how she responded beneath his touch, kissing and sucking all the corners of her throat and jaw line that had made her whimper and moan when they’d laid together before. He was glad to find they had the same effect now as they had then, and in no time her corset fell to the ground. Had she been of sound mind, she might’ve even thought it was magic that’d gotten the fastenings and ties undone so quickly, but given the groans that made her whole body vibrate as Loki hiked up her skirts, she wasn’t anywhere near sanity. He preferred it like that. Sif’s hands palmed her breasts, his mouth trailing a warm pathway down the front of Natasha’s throat, to her collarbone, then to suckle both of her breasts in turn. Her head tipped back as he took one of her nipples in between his teeth, nipping softly while Loki freed her of the rest of her clothing, the skirts and hoops and every other accessory that man could conceive to keep them from touching skin to skin fell to the ground.

Natasha was hardly able to croak out “Bed” before Loki had her up in his arms and away from Sif, causing the both of them to groan with displeasure at the loss of contact. It gave Sif more than enough time to divest himself of his own clothing, though, as Loki laid Natasha down on the bed and eased his way between her widespread legs. He could smell her arousal from the other side of the bed, and with his head between her thighs it was damn heady. His tongue flicked against the bud of her clit with slow, simple strokes that had her back arching and her moans gurgling in her throat before Sif closed her mouth with his own once more.

That only spurred Loki to try all the harder to make her moan, relishing the way her body vibrated as he hiked her legs over his shoulders and ground his face against her slick cunt, devouring her, starving for the taste of her and feel of her flesh tightening around his tongue. One of his fingers pressed into her sex, slick enough for him to slide it in to the knuckle, before pressing a second in with hardly any time wasted. Her back arched, one of her hands reaching to tangle her fingers up in his hair as the second reached out to stroke Sif. Loki’s eyes flicked upwards, the sight of the pair of them locked in a passionate kiss enough to send shocks down to his own cock, the tip already weeping with precome. He welcomed the slight friction that came from rocking his hips forward, the seam of his trousers at the perfect position to torment the hell out of him and keep him on edge, and as he caught sight of Natasha’s hand moving he found some strange twist of curiosity had his gaze following her movements. He nearly choked, the size of Sif more than considerable. Just how many liberties had the goddess taken in crafting this form?

Not to be outdone, and not entirely proud of his pettiness, he crafted a spell to alter his own body ever so slightly, just to give Sif some fair competition, and his clothing all but melted off to relieve the pressure that came along with it. Sif’s eyes on him as Natasha broke away from the kiss to gasp for air told Loki that he knew exactly what had happened and had he not been so caught up in the moment he’d have called Loki out on it.

Loki pumped his fingers faster inside of Natasha, eager to break the eye contact between himself and the other god, feeling her begin to tighten up around him before he pulled them out, and pressed one well-slicked finger up to the pucker of her ass. She writhed, eyes opening as she stared down at him. “What’re you doing?” she barely managed to gasp. Sif smirked, kissing the corner of Natasha’s lips.

“This will feel amazing, I promise,” Loki said smoothly, kissing down her inner thigh and smiling as well, his green eyes flicking up to catch sight of her red-tinted cheeks and opened, shocked mouth.

“That’s not--.”

“Trust him, my love,” Sif murmured in her ear, his tongue flicking out against the shell of her ear so that she shivered. Loki wondered if he remembered how the female Sif had tensed up similarly at the same suggestion, though that was centuries ago. “Relax. I won’t let him harm you; nothing but pleasure for you, my darling.”

It seemed to calm her down, enough to let Loki press the first inch of his pointer finger inside, slipping in slowly as she relaxed around him. The heat of her body was divine, and she was as accommodating as ever, he found, as he managed to fit a second finger inside of her, scissoring her further open. She moaned, and Sif helped guide her through it, his mouth flitting from breast to breast, tasting her sweet skin for himself before he moved a thumb to rub slowly against her clit. That helped with the third, and the inevitable fourth that she would need if Loki was going to fit himself inside of her. It was going to be a snug fit to begin with, especially if she’d never done it before, and he delighted in the thought of being her first. His gaze flicked up to Sif’s, who looked about ready to burst as it was, and motioned for him to turn Natasha on her side. It’d make it easier for the both of them, and with a quick dip of Sif’s head, he slowly pulled Natasha towards where he was lying down, slinging her upper leg over his own hips.

“Mind if I?” Sif asked, and Loki shook his head while Nat whimpered. Her forehead pressed forward onto Sif’s chest, hands tightening around his shoulders as he purred in her ear how well she was doing and pulled her further up towards his already aching cock. Loki paused what he was doing to watch as, inch by slow inch, Sif pulled her onto him. His own groans were higher pitched than Loki might’ve thought, more familiar now that he thought about it, and the memory of their own infrequent couplings as they’d grown up made him shudder. His hand inside Natasha worked all the faster, kissing her shoulder blades as Sif rocked with her. He kept her up against his chest, his hips languid as he pulled out, then pushed all the way back in in a slow counterbeat to Loki’s quickening thrusts.

He couldn’t wait much longer, though, and again he used magic to slick himself up. She wouldn’t be able to tell what had happened, and would be all the more grateful for it anyway, as he pulled his fingers out and guided his cockhead into position in its place.

“Do you trust me?” he whispered against her skin, her body vibrating against his even as she nodded, unable to find words. He wondered if there would ever be a world where he could live without this, without feeling her warm skin against his, without hearing the thrum of her heart as she came alive under his touch. Just as slowly as Sif had, he eased into her, hearing Sif’s muffled groan at the pressure against his own cock as Loki filled her up with minor difficulty. He only had to pause once, halfway through, to murmur that she needed to relax, and after some coaxing and a couple extra thrusts from Sif to help relax her muscles was Loki able to fit himself wholly inside her.

He thought she might die, her heart was beating so quickly in her chest, and it was only his terror that they might actually be the death of her that managed to keep him from rutting into her like some wild animal. Instead, he and Sif took turns pushing into and pulling out of her, only ever aligning when she grew closer to her first orgasm. Neither of them would be outdone by the other, and one of Loki’s hands reached around to palm her breasts as Sif caught her mouth with his own once more. She came apart beautifully between them, nails scratching into Loki’s thigh, hiking his leg up to force him to bottom out inside of her completely, her back arching to press her breasts against Sif’s bared chest. Such was the strength of her own orgasm that she pulled both men alongside with her, Loki’s own groan stuttering in his throat as the air was sucked from his lungs and he felt himself explode within her, Sif actually shouting at the sensation as he, too, emptied himself. Between them Natasha whimpered and went boneless, her skin burning and a smile twisting her lips as she kissed Sif, then turned her head to kiss Loki as well.

“Now, wasn’t that better than arguing over something stupid?” she asked, voice hoarse, and broken as Loki thrust quickly back into her for a half moment, before pulling out slowly. He couldn’t stop the smile from spreading over his own face, nodding.

“Yes, you’re quite right my darling.” He kissed her cheek, eyes catching Sif’s, who looked flushed and utterly debauched. “I’m looking forward to trying more out with the pair of you, if you’re both up to it.”
