Oral sex, Dom!Natasha, semi-sub!Loki, friends with benefits relationship

She'd been the first to initiate it, but really she couldn't be blamed; the timing had been too perfect. So when she'd been walking past the demigod the first time he'd been brought back to the tower she'd felt, rather than heard him, murmur something about her under his breath. In half an instant she had him flipped on his back, her toe pressing hard on his larynx and her eyes hard as rocks as she glowered down at him. He did nothing but smirk, looking up at her as his tongue flicked quickly across his lips.

"Such an interesting position for you to choose, Miss. Romanov," he purred from below, not bothering to fight against her, eyes flashing with amusement. "Filled with so many interesting memories." They both knew he could break away in a heartbeat if he wished, which meant that once more he was below her on purpose. As though he'd known how she would react. Fighting back the heat from rushing to her cheeks, she only pressed down harder with the tip of her shoe so that he started trembling from a lack of oxygen beneath her.

"You know, for as much as you use your mouth I can think of a dozen better uses for it," she snarled, bringing her foot down on his nose. The bone crunched beneath her, and though he cursed initially as blood seeped from the broken bone and cartilage his laughter was what stuck with her as she walked down the hall, her head held high and her hands clenched at he side. He'd heal, she knew, hoping that she'd at least made her point.

That night he'd wound up in her bed, the same hungry, heated look in his eyes when she entered as had shown when he was beneath her.

"Get out of here," she growled, hands flying to the gun holster at her side and pointing the weapon at his face. It wouldn't do anything other than hurt for a few seconds but it was a start.

"I had a proposition for you-."

"Not interested. Out. Now."

Raising his hands to either side of his head, he slowly stood, walking towards the same door she'd come in. As he grew closer he leaned in, ignoring the gun she was all but pushing against his temple: "You told me you had a dozen other things for me to do with my mouth. I'm curious if one of them involves pleasuring you."

She was ashamed of the tremor that ran through her body at his suggestion, but if she was entirely honest with herself then yes. He had such a silvertongue out of the bedroom she could only imagine what would happen if he put his back into it, metaphorically and literally.

"Wait." The words caught him just before he left, and in a moment he had turned to face her and she'd lowered the gun to her side. This is going to get me killed. He didn't say anything, didn't move, only stared at her as though she was the single most interesting thing in front of him. "How do I know it isn't a trick? You're not just trying to get me at my weakest?"

"Because I know you well enough to understand that it would be a monumental fool indeed to think that you are at your weakest at any moment."

Well at least he was learning.

She watched him, the memory of the last time they'd gotten together-the time in Cell A, where she'd had him chained and laying back, paying homage with his tongue to her cunt. She shivered a little at the memory and gave a quiet sigh. "Strip down and lay down on the bed. If we do this we do it by my rules."

"And what might those be, Miss. Romanov?" He asked, though his fingers were already undoing his vambraces one at a time, his eyes never leaving hers. It was practically pornographic the way that his fingers moved down the metal, taking it apart lovingly piece by piece, not needing to watch what he was doing out of how familiar it must have been. She cleared her throat to force herself to pay attention. Rules. Right.

"You come when I call, not the other way around. This doesn't go anywhere besides a friends with benefits relationship. Your benefit is that I deign to call you for sex." And hers was that she got to sit on his face or ride his cock whenever she felt like it. "I like to call the shots so don't argue with me. No one knows about this."

"Of course." He rolled his eyes, as though it was the most obvious thing in the world. He was down to his trousers now, having shrugged off the upper layers of clothing entirely, said pieces folded nicely on the desk beside Natasha's bed. She tried not to chuckle at that, getting to work on her own shirt, moving each button through the hole with precision that came from years of experience. More than once she caught Loki watching her, but as told he moved back onto the bed as soon as he'd removed his leather pants. No boxers or anything. Interesting. She finally shifted her own panties down her hips, not intending on making it a show but the way that Loki's breath had caught in his throat brought back the memories of the first time. Immediately the heat pooled between her legs again but she forced herself to calm down. It wasn't the time to get bogged down with the past. She came towards him from where his head was laying, crawling atop him so that her slick cunt was positioned above his mouth. She heard a low growl of pleasure from somewhere in his chest and met her halfway when she finally brought her hips down. There was no reservation this time around, his teeth grazing her clit before his tongue swirled around it, then delved deep into her slick heat. A loud moan of surprise and pleasure worked its way out of her mouth, stars blinking in the back of her eyelids, and her body shuddered as she arched her back, driving her hips down further onto his mouth. In this position, with his cock already in front of her, she couldn't help but extend herself further a little and grasp his warm, thick organ in her hand, propping herself up on the other one, before bringing her mouth down and swirling her tongue around the head. From beneath her she felt him vibrate with a moan, mouth otherwise occupied, and she needed no further encouragement before she brought her mouth down his whole length. He was much larger than she'd remembered, and it took a little more time for her to adjust to him so she could fit him entirely down her throat. Nothing she couldn't handle, she reminded herself, tongue coming out to flick the base of his cock, lips tight and hot around him. He was a lucky man; she only did this when she was in the mood for it, and she'd never heard any of her partners tell her there was anything wrong with it. Loki, encouraged by Natasha's own efforts, worked his tongue further into her, devouring her alive so that more than once she lost her concentration in the steady thrum of pleasure that rocketed through her body. She came more than once by his tongue, the sensation one of the most intense things she'd felt since, well, the first time they'd done it.

By the time he'd met his own climax he'd more than made up for any hesitation she might've had to begin with, and he burst, hot and salty sweet in her mouth, tasting just as good as he had the first time. Her hand pumped his length as her tongue worked around the tip, cleaning him up before pulling away, his moans still echoing in her ear loud and clear. They parted, both lying on their back, sweaty and panting and not meeting eyes. After a minute or so Loki stood, dressed quickly and departed without another word.

He came back two days later when Natasha was reclining and reading a book, turning the pages slowly as she tried to focus on the plot and not the way his fingers pulled at the yoga pants, or hummed with happiness to find her not wearing any panties. He slotted himself between her legs, going slowly this time around, the flicks of his tongue against her bundle of nerves lazy and timed so that she gave a quiet sigh and rock of her hips as she came near the very end of the book.

"I thought I told you I would come to you, not the other way around." She said as she looked down at him.

"I was bored."

"Fine." She shrugged. Not that she minded it if she was totally honest.

Nat sauntered to his small, nearly pathetic excuse of a room later that week and upon hearing the shower running she quickly stripped and stepped inside.

"What-."

She sank to her knees in front of him, his body positioned so that the water hit his back and not her face, so that when she drew his cock into her mouth he growled and gasped, one fist hitting the wall as he tried to keep himself from bucking his hips into her mouth. She didn't mind, one hand grabbing a handful of his ass to massage the muscle as she worked, deep throating him with ease now that she'd practiced on him before. Another hand massaged his balls, drawing one of her nails lightly over the skin separating them. He came with a gasp and a mangled snarl. She swallowed him without issue, looking up through her lashes as she did and tapping his legs. He looked down immediately and she watched as his pulse quicken. Good. She wanted him to look and see who was giving him the best blowjob of his life. Well, thus far at least. She was just getting started.

A/N: Thanks so much for reading, and I hope you enjoyed it! Turned into a Friends with Benefits fic at the request of the-silver-trickster from Tumblr!
