Chapter Text
Natasha wasn't sure how they'd wound up like this. One day she was the same as always, negotiating a world in which she'd given up the anonymity she prided herself on in favor of living a life surrounded by her friends, and the next she was restraining a super-soldier to his headboard with cuffs made of titanium laced with steel and just a bit of adamantium she'd charmed off a contact to add to the mix. Tony had constructed the cuffs themselves for her, no questions asked, though Natasha did spend some time once she had them thinking about what she was doing as she turned the shiny restraints over and over again in her hands.
This was probably one of the worst ideas she'd ever had- and she'd had some pretty terrible ones.
It all began nearly a week ago, when all the Avengers had been gathered in the main living room in the Tower, drinks all around. The evening had been filled with teasing and laughter, long stories shared by Thor and Steve, little anecdotes by Sam (honorary Avenger) and Clint. Natasha put in a word or two here and there, which Bruce did as well, when he felt like he needed to. All in all, it was shaping up to be a good night. But at some point, the teasing became something a little less innocent and a little more Comedy Central Roast.
Pretty much everyone took Tony's comments in stride, but something he said must have hit a nerve because Steve took a sip of his drink and countered back with something pretty nasty of his own- but something that wasn’t meant to be taken as a joke. It was an uncomfortable silence that fell after that, and Natasha decided that she would be the one who spoke up. “Lighten up, Cap.”
Clearly, that had been the wrong thing to say. “Make me,” he responded easily. It wasn’t a real challenge, but Natasha came to the conclusion that unless someone made him relax, he was never going to. It was in that spirit that she hatched this ridiculous plan- a plan she hadn’t really been sure she would see through until the moment she’d pinned him down in the gym and realized that he liked it way more than he should have.
So. Captain America really liked a woman who could put him in his place for a little bit.
She could do that.
She plotted very carefully, eventually luring Steve into his own room with the promise of having ‘a talk’. Natasha wasn’t blind- she saw how he looked at her sometimes and she was ready to make sure she got to see her in a different light. As soon as he sat down on his bed, she attacked, wrestling with him for a moment before cuffing each arm to the headboard via her two sets of cuffs. Perfect.
“Nat, what the hell?!” he exploded immediately, pulling at his cuffs with the assumption that they would break and only struggling further when they didn’t. “Let me go, goddamnit!”
“No.” Natasha folded her legs under her as she sat beside him, laying one hand on his chest. “You told me to make you loosen up. I’m only following your orders, Captain.”
Steve blinked in surprise and his attempts to break the cuffs grew less panicked as he figured out that she was serious. “What are you gonna do?”
Smirking a little, the redhead trailed her fingertips over his chest and down to his stomach, finding the outlines of his abs through the thin material of his tshirt. “I’m going to wear you out,” she said smoothly, continuing the movement of her hand until she was toying with his belt. “How does that sound?”
His Adam’s apple bobbed as he swallowed and licked his lips, pupils dilating. “Okay.”
Good. Consent acquired, Natasha went ahead and straddled his waist, sliding both hands up the length of his torso and raking her nails back down to make him shudder. His tshirt had to go. “I hope you’re not attached to this.” In a moment, she’d extracted a small knife from underneath the bed (something she’d stashed there earlier) and cut his shirt in a few practiced movements until she could pull the remnants off of him and toss them aside.
Step one complete. Leaning down, she set about kissing his jaw, working her way down to his neck and leaving a line of slight bruises over his pulse point and down to his clavicle. Natasha worked tirelessly and made sure that 'thorough' was not enough to describe how fully she explored and worshiped every single inch of his chest. Her lips brushed over his nipples one at a time, tongue swiping over the hardening buds as she made her way down to his abs, tracing along his flank until he shuddered and let out a shaky breath, like he was trying to hold onto his control. He had no control anymore, but he would realize that eventually.
Continuing down, she deftly undid his belt and tugged his pants down without hesitation, kicking them off the end of the bed while she knelt between his legs and continued kissing his lower belly, brushing over the trail of light blonde hair leading down, and nipping at his sharp hipbones. She traced a long line to his groin, unabashedly nuzzling into the crease of his thigh before she turned her head and let her lips glide over the side of his length. He was already hard, his cock jutting up proudly, as impressive in size as in actual appearance. Like the rest of Steve, it was perfect and pretty, with a big, flushed head and a thick vein running up the underside.
Glancing up, she smirked dangerously at how he was watching her and slipped her lips over the head, lightly sucking right there for a moment in order to earn a deep groan. He shifted just once, pressing his hips up, and Natasha placed her hands on his hips, pressing down and letting her nails dig into his skin. It was a warning. He was not in control. He would not move, or she would punish him.
Like the good soldier he was, Steve let his head fall back and his hips stilled, so Natasha continued to see to him. Her lips slid down, slowly taking him in until her nose was nuzzling into the coarse hair at the base of his dick. Lifting her mouth off, she gasped a little and licked her lips, immediately bowing back down to do it again. This time, she didn't take him all the way in. Instead, she sealed her lips around him and bobbed her head slowly, letting her hand stroke whatever she couldn't reach. This wasn't about getting him off quickly- it was about satisfying him to such an extent that he could relax for once in his life.
But she would make him come. Letting her other hand slip down, she cupped his heavy balls and rolled them very lightly in the palm of her hand, her nails just barely brushing over the sensitive skin of his perineum. If he liked this, she would be exploring that kind of stimulation at another time. Right now, she hollowed her cheeks and sucked hard, all too aware of the wet sounds filling the room and the way he was groaning openly, his chest heaving and his hands tightening as he tried not to move his hips and chase his release. Soon enough, he came with a low groan and half a warning, leaving Natasha with just enough time to ready herself and swallow down his release-- to keep everything neat, of course. They had a long night ahead of them, and getting all sticky wouldn't help anyone.
Slipping off him again, she pressed a line of hot, wet kisses up the length of his torso and the side of his neck, eventually pecking him right on the lips. “Was that good for you?” she teased, giving him a smug grin. Steve groaned and Natasha took that as a yes. “I'm glad. We're only getting started.” Slipping away from him, she made sure that he'd turned to watch her before pulling her shirt over her head and unhooking her bra as well. Now, the look in his eyes-- the one that told her he'd thought about this and was generally very pleased by this turn of events-- was a look she lived for.
As she slipped out of her tights and panties as well, Natasha made her way back to the bed and straddled his hips, lightly pressing herself down against his softening cock and relishing the shiver that ran through him. While he worked himself up again, because she had no doubt that the serum would reduce his refractory period to a truly crazy extent, the spy decided to use him for her own pleasure. She knew Steve well and if his hands were free, she had no doubt that he would be a generous kind of lover. He probably loved to serve. “My turn,” she said by way of a warning, kissing him full on the mouth before turning around and bracketing his head with her thighs.
To her surprise, he leaned right up to her and she had no choice but to press down, moaning as his tongue moved over her folds. Yes, he was inexperienced. Yes, he was overly eager and her brow furrowed as she shifted to show him the way, but he made up for all of that with sheer enthusiasm and a learning curve that would make Tony jealous. Scraping her nails over his flanks, she arched her back and rolled her hips, taking pride in the way she could see his cock twitching and swelling against his stomach.
Eventually, she sat up and planted her hands on his chest, using her knees for balance as he found her clit and sucked experimentally, earning an embarrassingly loud moan from the woman above him. Natasha came not long after that, thighs tensing as she fluttered and pulsed against his mouth. Slowly coming down from her high, she moved away from him and again kissed him full on the mouth, groaning into his as she tasted herself on his tongue.
“Nat,” she felt him gasp, the cuffs knocking against the headboard. “Please.”
Did Captain America just beg? Natasha’s lips quirked up into a grin and she leaned in close again, just barely brushing her lips over his. “Please what?”
He shivered again and she smiled devilishly against his lips, quite enjoying the effect she had on him. “I need… I want…” Steve cut himself off there and Natasha wondered if maybe he didn’t quite know what he wanted or needed. She’d help him out this time, but next time she’d demand to hear him say the words.
“I’ve got you,” she said confidently, keeping her voice even and smooth as she straddled his waist and rubbed down against him, sliding her slit over his hard length. “Relax.”
Locking their eyes together, Natasha pushed herself up and reached down to guide him into her as she sank down, parting her lips as she stretched around him. The look on his face was priceless- a silent, broken gasp from parted lips and a creased brow that made it look like his mind was just overcome with pleasure. It was quite the boost to her ego.
Once she’d settled on top of him, Natasha stilled and let her hands idly drift up and down his chest, teasing his nipples because she knew that by then he was oversensitive. Every little touch was like a spark that ran up his spine and pulled a needy sound from deep in his chest. Eventually, though, Natasha simply planted her hands on his chest and rolled her hips- an action that made Steve’s arms tense to the point where the headboard was under some serious pressure.
Grinning wickedly despite her own panting, Natasha continued to roll her hips, rutting down against him without pause or mercy. She was just as fired up as he was, her swollen clit rubbing against him with every movement of her hips and his cock pulsing inside her. Natasha didn’t know what was better- the way he was chanting her name like a prayer or the way he was trying to dig his heels into the mattress under them to roll his hips against her in return.
He came apart for the second time that night when she raked her nails over his nipples once again and tightened around him while she continued to move. The headboard, which had been holding up pretty well considering the circumstances, cracked under the sudden pressure as Steve bucked up into her and came hard. As her movements slowed to a lazy rhythm, Natasha reached up and touched his jaw, leaning down just a little bit to press their lips together. “See?” she murmured. “I’ve got you.”
Steve let out a huff of breath and Natasha almost felt bad for what she was about to do. Almost, but not quite. She gave him a few seconds to recover, pressing warm, wet kisses over his lips and jaw until she tasted the sweat beading on his neck. He was still inside her, twitching and softening as time went on—until she bit down on his shoulder. He moaned openly and Natasha stroked her fingers along his chest to soothe him, lightly tickling under his ribs. This time, she began to move her hips in very slow, tantalizing movements, continuing to kiss over his hot skin until she could seal her lips around one nipple and tease him further.
Again, the headboard groaned in protest as Steve instinctively tried to reach out for her. “Be patient,” she scolded lightly, leaving a trail of kisses across his chest until she came to the neglected bud and sucked that between her lips as well. As expected, Steve rose to the occasion for a third time, growing hard inside her and panting as he tried to shift his hips a little for some friction- friction that Natasha wasn’t ready to give.
She tightened her thighs and he stilled, clearly getting the picture and, to her surprise, obeying her silent command. She praised him in her head rather than saying it out loud to humiliate him. After that, he didn’t have to wait much longer anyway. Curling her legs up so her knees were on either side of his ribs, she leaned forward and grabbed the headboard between his hands, looking down at him only to find him watching her intently.
There didn’t have to be any discussion or orders given because he knew what to do. Steve bent his legs and spread them a little, giving her a seat as she started to bounce up and down, her breasts brushing against his chest every so often. It wasn't horribly coordinated, but Natasha's ass hit Steve's thighs every time and soon enough, he was really planting his feet on the bed to meet her thrusts. Sweat rolled down the curve of her spine as she continued, tirelessly working towards her own release and urging him towards his as well, the sound of their skin slapping together filling the air around them along with their shared moans, her breathless panting, his desperate whispers of her name.
By the time her legs started to ache, it was clear that they were coming up on Steve's third orgasm of the evening, based on the way the headboard was bending and nearly splitting in two as he tightened his arms and desperately tried to find some kind of leverage. She came first, gushing over him as she shivered and tightened around him, her eyes slipping closed for a moment or two.
Steve didn't relent. Oversensitive and sickly determined, Natasha met his eyes and moaned, leaning down for a fierce, open mouthed kiss that swallowed garbled swears and pleas as he followed her example and spilled inside her again. He'd dealt with this so well. Natasha was sure she was getting her point across and if not, she would be sure that he understood when he woke up after a full night of deep, restful sleep. Pulling away, she let him slip out of her and immediately got to work again. Third time? No, the fourth was the charm. It was the fourth that was going to really do this for him.
There was something akin to disbelief in his eyes when she settled between his legs, palming over his still half hard length and coaxing him to hardness once more. Using just her hands, she stroked and teased, cupping his balls as she worked him through a fourth release. This time, he was barely able to move, moaning weakly and letting his head fall back in defeat.
Slowly, Natasha crawled over him and pressed a few slow kisses to his lips, gently brushing their noses together. It was important that he come down from all this, boneless and sated as she had always intended him to be. When she let him slip out of her, she casually left the bed for a moment and returned with a washcloth, cleaning him up and getting most of the wetness off her inner thighs as well.
Again, she disappeared from sight and this time came back wearing one of his tshirts. One look at Steve told her that he was speechless, his lips barely parted, his eyes half lidded. Perfect. She knelt beside him to free one hand, then the other, laying the cuffs down on the bedside table for the moment and helping him shift down into the bed, pulling the sheet and blanket up over both of them.
Still nothing, but she settled against him, tucking her head into the crook of his neck and splaying one hand out on his chest, her leg hooked over his hip. The next time she looked up at him, he was asleep and snoring, one arm lightly curled around her waist and the other thrown up over his head. It was the most at ease and relaxed she'd ever had the pleasure of seeing him. Smiling to herself, Natasha drifted off only a few minutes later and didn't wake until the sun was shining.
With some sense of accomplishment, Natasha noticed that Steve was still fast asleep. She chuckled quietly and slipped away, standing in front of his mirror to push her curls out of her face-- and that was when she heard a gruff voice behind her. “G'morning,” he mumbled, and she caught a charmingly tousled soldier's reflection in the mirror. “You wanna tell me what all that was about?”
So he didn't get it. Alright, then. Natasha could do things his way. Huffing out a laugh, she casually pulled his tshirt off and let it fall to the floor, glancing over her shoulder to give him a teasing look as she made her way into the bathroom for a shower.
“Make me.”
