Warning: more top Katya and more bottom Nat. Aka more smut :) And it's a lot, let me tell you. Did not proof-read this. Reason at the bottom :(

''You're such a fucking tease,'' Katya growled, pushing her chuckling wife further into their bedroom as she locked the door. A habit, because nobody was around.

Natasha kept teasing her the whole night, placing her hand on Katya's thigh while she drove home and slowly dragging it upwards, only to trail her fingers down to her knee and do the same all over again. The entire half-hour drive back home. It wasn't much, but Katya was such a sucker for her wife that the simplest of touches turned her on. Especially after it already hung in the air with Maya out of the house and that dress on her curvy body.

On their way to the bed, she quickly regarded Natasha's dress. It slipped off her shoulders and pooled at her feet, Katya's blue eyes widening when she saw the lace set Natasha only wore to get exactly what she wanted. A groan left her lips, eyes trailing up and down to drink everything in.

With another push, Natasha fell backwards on the bed, a proud smirk on her face.

''You planned this, didn't you?'' Katya asked, crawling between her legs and leaving teasingly light kisses on her neck. Ones that didn't do anything to suffice her needs. She felt Natasha nod, her fingers weaving into her brown hair and pushing her face closer to her neck, whishing Katya would suck on the skin already. ''Words, Nat.''

The grip on her hair tightened at the order. Who would have thought Natasha Romanoff got turned on being told what to do?

''I did.'' Her tone was already submissive, although she tried not to give herself away too quickly. Her chest rose and fell faster than it should have, though.

Katya sunk her teeth into her neck as a response, Natasha hissing and wrapping her legs around her waist to keep her there. Katya smiled at the reaction, soothing the bitemark with her tongue before pulling her head back and connecting their eyes. 

She sighed, her breath ghosting over Natasha's lips because of how close they were. ''What am I supposed to do with you?'' she asked, exasperated.

''You can always fuck me as my last birthday present today,'' Natasha muttered teasingly. Her eyes were wild, the pupils dialated as her fingers played with Katya's hair. Those were the only signs that she was about to let herself go. Her composure still holding on but slowly crumbling underneath the surface.

Katya hummed lowly, looking at Natasha's lips and brushing her own over them. ''Tempting. Or I could just leave you and your needs unsatisfied.'' They both knew she'd never do that.

''I'd just do it myself then.''

Katya narrowed her eyes at her, dangerously. ''You wouldn't dare.''

But she did dare. One hand left Katya's hair and slowly trailed down her own body, in the small space between them, looking Katya dead in the eye the whole time with a sly gleam in her eyes, challenging her to stop her.

With a growl, Katya took her wrist, together with her other one, and pinned them to the bed, Natasha whimpering because of her roughness. ''These need to go.''

She sat up, pulling her own dress over her head in one fluent motion and went to tie Natasha's hands to the bedpost, but not before looking at her questioningly. It was a huge honor to get to top, showing how much she trusted Katya, and so the brunette always made sure to ask permission first for whatever she was doing.

When Natasha nodded quickly, her wrists ended up above her head comfortably, but tight enough so she couldn't lift them more than a few inches off the pillow.

Katya sat back and drank in the sight before her. Natasha, half naked, all laid out for her. Her toned stomach, full breasts, amazing skin that begged to be touched, the beautiful thighs that were wrapped around her waist.

''So pretty, baby,'' Katya complimented her, bowing down to kiss the top of her breasts. ''такая красивая. (So beautiful).'' That did it, earning a small moan that Natasha could finally let go, now that Maya wasn't here tonight.

''You like the Russian, don't you?'' Katya smiled. But that fell quickly when she didn't get an answer. ''Words.''

''Shit, I do,'' Natasha answered, slightly embarrassed by it and by having to admit it.

Katya smirked and finally went to take off her bra - a strapless one so she didn't have to untie her again - drooling over her breasts as usual. She heard a small whimper from Natasha because of the way she looked at them, and she shifted underneath her impatiently, wishing she'd touch her already.

Without warning, she took one of her nipples in her mouth, flicking her tongue over it. Another deep moan left Natasha's lips, her arms tugging on the ties in a reflex, wanting to lace her fingers in Katya's hair again to keep her mouth right there. 

It made Katya smirk, but she didn't stop doing what she was doing. Swirling her tounge around, sucking. And her hand found its way to the other breast, giving it the same attention.

Natasha couldn't decide if she wanted to watch or let her head fall back into the pillow. But when Katya switched her hand and mouth and scraped her teeth over her skin, she did the latter after letting out a gasp, closing her eyes and enjoying the feeling.

The more Katya worked, and used her free hand to slide over every piece of bare skin of Natasha's body she could find, the more desperate Natasha grew, using her snake-like grip on Katya's waist to try and find any friction. Her heartbeat was through the roof, and because of the frustration of not getting touched where she wanted to, she panted quietly.

Katya let her grind on her for a while, having to swallow her own moans because of how hot it was that she used her. Letting her breasts for what they were and kissing up her neck to her ear, she finally used a hand to teasingly still her hips. ''Tell me what you want, милый. (darling).''

''Fingers. Now,'' she breathed, giving up in trying to fight the strong grip on her hips but keeping her eyes closed in anticipation. As if Katya would give in so quickly.

She chuckled lowly, the sound sending shivers down Natasha's back because it meant bad news. ''So impatient,'' she husked, kissing her neck and slowly trailing her lips up, pulling Natasha into a deep kiss which she didn't saw coming because her eyes were still closed. She shivered in anticipation when one of Katya's hands trailed down her stomach, lower and lower, until suddenly Katya touched her nowhere. ''You were a tease tonight, so I'll let you wait.''

Katya smiled as she sat up, watching Natasha's eyes snap open. ''No, ple-'' She cut herself off just in time to swallow the word, her cheeks turning red in frustration.

But Katya heard it, and her smile merged into a satisfied smirk instead. ''What was that, baby?''

''Nothing.''

''Pretty sure you were about to beg me.'' Katya bent down, bringing her lips to her ear again without touching her anywhere, practically feeling how needy and desperate she made her wife. She usually never let her wait this long. ''Because you can't just walk off and leave your wife unsatisfied. But I can.''

A scowl formed on Natasha's face. It had been enough teasing for her and she started to get mad. ''If you don't stick your fingers down there right now-'' Her words cut off with another moan when Katya finally touched her where she needed her, cupping her and starting to rub her agonizingly slowly through her underwear, feeling how wet she was already.

Natasha's hips jerked because of the sudden contact and she released her legs' grip on Katya's waist to give her better access. Her head fell back again, mouth slightly open, eyes closed with her arms still neatly in their ties. And Katya just sat back and watched her, because what it a better sight than seeing your wife in absolute pleasure, knowing you did it to her?

''Then what? Then what, малыш (baby)? I didn't hear the end,'' Katya teased, knowing damn well she'd both regret this later and was enjoying this too much. When Natasha stubbornly kept quiet, she sped up her movements on her clit, watching her fall apart under her touch.

''Please,'' she finally threw out, both the Russian and Katya's dominant tone too much.

''There it is,'' Katya smiled. It was all she needed to hear.

Impatiently pushing Natasha's panties aside, she ran her fingers through her folds one time before slowly pushing her fingers in. She wasn't entirely done teasing yet.

Natasha let out a deep moan, her back lifting off the bed before it fell down again. Her hands gripped the fabric they were tied up with, mouth falling open. All the while, Katya just sat there, smirking in satisfaction.

''God, I hate how cocky you get,'' Natasha managed to say as a response to Katya's earlier words. She had opened her eyes and looked at the woman between her legs, swallowing a moan at the sight.

Katya chuckled lowly and sped up slightly, wanting to drag this out as long as she could. ''That's not what your pussy says, darling.'' She chuckled again at the glare she got, deciding to shut it up with a hungry kiss that added to the pleasure happening between her legs. 

When she got her tongue in, Natasha tried to fight her, refusing to give her full dominance. But then Katya simply cheated and pressed her thumb to her clit, causing her to moan again and losing focus.

''Yes, baby,'' she gasped, enjoying the circles Katya's thumb ran, calculated, precise, making sure to give her the best she could.

When Katya sped up again and dragged her lips down to Natasha's neck, sucking harsly on it, continuous sounds of pleasure escaped her lips, her hands falling down above her head again because she was completely focused on the pleasure running through her.

''Fucking hell, Kat,'' she gasped, squeezing her eyes shut and tilting her head back to expose more of her neck. Another moan tumbled past her lips when Katya sucked on her sweet spot and curled her fingers at the same time, finally hitting that sensitive spot inside her that had her screaming on good days. ''Oh my god, yes.'' Her heart raced out of her chest as Katya kept pushing her fingers in and out faster and faster, feeling how her walls clenched around them.

''You look so gorgeous, love,'' Katya mused, pulling back from her neck to watch her scrunched-up face.

After years of this, she knew exactly when Natasha was going to cum. Knew the signs perfectly. Her hips would get restless, trying to move in sync with the thrusts to increase her pleasure and get there faster. She'd throw her head back as far as she could, moans growing louder and frequent. And most of all, her thighs would start to shake violently. Katya could feel them tremble next to her own hips.

''You gonna cum for me already?'' Katya asked teasingly, once again picking up the pace, hitting all the right spots and rubbing her clit intensely. The sounds bouncing off the walls of the bedroom were music to her ears, absolute music. At her words, the walls around her fingers tightened even more, and she could only imagine the knot about to snap in her wife's stomach.

''Yes,'' she moaned, hardly knowing what to do with herself anymore. At this point, she was a sweaty mess. ''And I hate it.'' 

Right when she was about to let go, Katya's fingers stilled and pulled out alltogether, cutting off all the pleasure she received. It was mean, really mean, but she couldn't help it. Completely stunned, Natasha's eyes snapped open and her head lifted from the pillow to look at the smug woman by her thighs. ''Wha- Katya.''

''You said you didn't want to cum yet,'' Katya said casually, stuffing her fingers in her mouth, moaning at the taste on her lips. She was so eating her out after this. If possible, Natasha's eyes darkened more, biting her lip to smother her whimpers.

''I was so fucking close and you know that damn well. Make me cum, goddamn it,'' she growled, absolutely mad now.

''Magic word?'' Katya casually smiled.

''Fuck you.''

''Try again.''

She contemplated her options, but who was she kidding? She needed to cum really badly. So with a sigh, she muttered, ''Please.''

Immediately, Katya's fingers were back in. Only there were three instead of two, Natasha almost screaming out at the intrusion. Katya picked up where she left off, not bothing to start up slowly again. Her fingers curled, hitting her g-spot, her thumb on her clit again, circling aimlessly and tiredly. Natasha let out gasps, moans and whimpers time after time, her walls already clenching again after she got edged previously.

''This what you wanted?'' Katya breathed, connecting her lips to one of Natasha's nipples again, licking it aimlessly and scraping her teeth over it, her back lifting off the bed again to push her chest closer.

''Fuck, yes. So good,'' she moaned, legs trembling. Feeling herself get close again. ''Please let me cum this time.'' Katya topping and being to dominant turned her on so much. She was so quickly brought to her high like this, leaving her body to Katya's mercy, knowing she could trust her to take care of her completely.

Katya lifted her head from her chest, smiling at the words Natasha used. ''Alright. Cum for me, darling.''

The loudest moan yet left Natasha's lips as she let go, her legs shaking like crazy and her eyes rolling backwards until they closed. Her hands tightened around the fabric that had them tied to the bed, hips twitching and back lifting off the sheets again.

Katya watched her with her own wide pupils, following her flailing hips as she continued to push her fingers in slowly, dragging the orgasm out as long as she could. Not that she had to, because the edging from before intensified it already. She could feel the warmth on her hand without having to look down.

Natasha let out a deep sigh and fell back onto the bed, entire body tired out. Her eyes opened and found Katya's because they weren't far. A lazy smile formed on her lips, and Katya caught the hint of needing a kiss. So she did exactly that, meeting her wife's in a gentle and lovely kiss as she pulled her fingers out, which was met with a whimper.

''You good?'' Katya whispered when she pulled back, looking into Natasha's deep green eyes. She knew to speak up when Katya did something she didn't like, or if she hurt her in any way, but still, she liked to make sure she was good afterwards.

''Perfect,'' Natasha promised, her eyes shining challengingly. ''I could go another round though.''

''Are you sure?'' Katya asked, not wanting to overwork her.

Natasha nodded slightly as Katya brushed some baby hairs off her sweaty forehead. ''Eat me, baby.''

Katya grinned like an idiot. She prefered eating her out over fingers, because of the taste in her mouth. ''Can't say no to that. Let me get these first because I love your hands pulling on my hair.'' Quickly, she reached up and untied her hands, groaning when kisses were placed on the skin under her breasts.

As soon as her hands were free, Natasha grabbed Katya's hand and licked her own juices off, looking her head in the eye the whole time. ''I'm gonna eat you out after this,'' her soft voice followed, and Katya had to swallow her moan to keep her composure, ignoring how wet she was herself. She could honestly get off just watching Natasha.

''Better be a promise,'' she breathed, tugging Natasha's panties off because they were never gone, just pushed aside. Slowly, she pushed her legs apart and crawled down until her face was lined up, looking her wife dead in the eyes as she licked a broad stripe the whole way up. Natasha gasped loudly and dropped her head back on the pillow, her hands indeed finding Katya's hair like she wanted.

Slowly, Katya started to eat her out, careful because she knew she was still sensitive. Her own soft moan left her lips at the taste, sending vibrations through Natasha's core that had her moan in return. Katya left licks all over and gave her clit the attention it deserved, cirling around until Natasha pushed her face closer, a silent signal to go faster, go deeper.

So Katya did, wrapping her hands around Natasha's thighs and lifting them so they were over her shoulders, diving in more. ''God, you taste amazing,'' she groaned, knowing talk like this turned her on more. And it did, the tugging on her roots increasing. Finally, she wrapped her lips around her clit and sucked, hard, surprising Natasha completely.

Her hips bucked and she let out another moan. ''Oh, fuck.'' With her, if Katya acted fast, her second orgasm was never far behind. The thighs around her head tighened, making it harder to hear the sounds of pure pleasure falling out of her wife's mouth as she continued sucking and licking the best she could. And they were loud, a lot louder than usual, because for once nobody could hear them.

''Katya,'' Natasha whined, not sure what she begged for. All her give-aways came back, although her legs never stopped shaking in the first place. Katya knew exactly, exactly how to work her body after all these years. Which trics did what and what Natasha needed.

''I got you, babe,'' Katya muttered, looking up at her as she stuck her tongue in, earning a loud gasp and a deep moan in return. God, she looked stunning with her eyes squeezed shut, letting herself go completely. 

The fingers in her hair clenched into a fist, tugging on her roots almost painfully now. But she only saw that as an encouragement and went faster and deeper, Natasha's moans growing in volume as she got closer to her high, her chest heaving. And Katya had to do her best to keep the smile off her face and focus on the task. 

''Let go, babe,'' she whispered, reaching around and using her cold fingers to rub her clit. With a lot of noise, Natasha did as ordered, cumming in Katya's mouth. ''Good girl.'' The brunette happily swallowed all of it, moaning at the taste as she licked everything clean. Because she'd choose this over any food. 

''Shit,'' Natasha chuckled breathlessly, a tired smile on her lips as she lay there completely exhausted. Her stamina wasn't what it used to be. ''You know how to wear me out.'' Her green eyes focused on the head between her thighs, watching her run her tongue carefully, ignoring another flutter low in her stomach. She'd already gone two times, she'd have to give Katya something back first.  

With her own chuckle, Katya crawled up her body and stared down into her eyes lazily, letting Natasha cup her cheeks and press a deep kiss to her lips. Both of them were breathless, so it didn't last long, the break very welcome. 

God, Katya loved this woman, who entrusted her sweaty body to her completely. She wanted to whisper those words to her, or ask her if she was still alright, if not for Natasha's eyes starting to twinkle more, clearly ready to continue this. 

Without warning, she licked her own mess off Katya's chin, her hands still on her cheeks. Another wave of pleasure shot down at the taste of herself, and she couldn't wait to taste Katya next. ''Your turn,'' Natasha smirked, seeing her blue eyes darken.
