A/N: This chapter involves gags, which might make it a slightly dub-conny sounding experience, and involves Pietro/Nat in an established relationship. There's also slight femdom, restraints, and orgasm denial thrown in for good measure.


She'd figured from the first time that they'd met that Pietro was going to have a mouth that would rival Clint's, maybe even Tony's if he tried hard enough. It came with the territory of being the older twin, she guessed, used to having to talk his way either in or out of situations, having to use that mouth to protect Wanda or cheer her up. It was a natural reflex, she mused. Didn't mean she wanted to hear him running it off all the time.

Natasha licked a slow, long stripe from the bottom of Pietro's cock to the very tip, the muffled whimpers of pleasure coming from the man in front of her twisting her lips into a cruel, slow smile as she looked up through her lashes to stare at him. His thin lips were stretched wide over the ball gag she'd produced half an hour ago, his hands locked up in the handcuffs she'd borrowed from Steve's room (not like he and Tony needed them when they were downstairs bickering over something she didn't care to think about). He was gripping the edges hard, knuckles white, and she could all but hear his teeth biting into the plastic of the gag.

"Pietro, don't bite through that," she hummed, pressing a slow, gentle kiss to the very tip of his cock before swirling her tongue around the crown of it to catch the precome that had dripped down. In response he bucked his hips up against her mouth, trying to end the torment that she'd been hell-bent on drawing out for far longer than she was willing to bet he'd ever been forced to wait before. He was a sort of instant gratification type of man, she thought as she wrapped her hand around his dick and slowly pumped him up and down. With her spare hand she held his hips down, preventing him from getting any extra help, and the choked whine sent a thrill up her spine and made her nipples harden with arousal. Not that it was difficult; seeing him prone, begging muffled against the gag, was doing more than enough to turn her on.

"You've got to learn to be patient, Pietro," she said, her grip on the base of his cock tightening to help stave off his orgasm. The color rose in his cheeks at the way that she said his name, nostrils flaring as he stared down at her. His pupils nearly swallowed the thin ring of blue left of his irises, and she watched with eager eyes as the flush traveled down his pale chest. "God I could just eat you alive, darling," she purred. The look in his eyes told her that he didn't necessarily consider that a bad thing. She gave a low, guttural laugh at that. With an easy grace she shifted her hips closer to his, running her soaked core against the length of his cock. When she grabbed his attention she caught sight of a certain glimmer of desperation that had her salivating. What would he do, she wondered, if she kept him like this for hours at a time? Already she could hear him begging against the gag, but without his usual litany of quick, clever things to say he wasn't about to charm the pants-or plans, in this case-from her. How long could he stand it?

He felt wonderful against her, solid, practically pulsating with his need for her body and attention, and she bit her bottom lip as she struggled with her choices. "Do you want me to fuck you now?" she asked, voice soft.

"Yes!" That much she could make out from around the gag, and it widened her grin. "Please," came next, though it was a little more difficult to make out. Shifting out of her original position, she moved herself until she was balancing just atop him, her hands on his chest, slit poised just above him. Did she dare? Tantalizingly, she swayed her hips back and forth, reaching out and pinching one of his nipples when he tried to thrust up into her. He shouted, and the gag swallowed the noise, forced it back into his throat until it mingled with a groan of relief and satisfaction when she finally lowered herself onto him. He felt amazing, and she took her time rolling her hips as she grew accustomed to his length. For being a scrawny little thing, color her impressed.

Her pace was slow, teasing, and she'd mix it up by pulling herself up and off of him entirely just to hear him shout and plead for her to come back, before easing herself onto him once more. She leaned in and kissed her way around the gag, tasting the salt of his sweat on her lips when she wetted them with her tongue.

"You keep making things more difficult on yourself. Trust me, Pietro." She reached out to stroke the side of his face, her own expression softening as she watched his adam's apple bob and the flush deepen further. "Let me ride you how I want and I promise it'll be worth it. Think you can give up control for a little bit?" She leaned in and took his earlobe into her mouth, biting it gently.

His breath hitched, back arching, but he kept from thrusting up into her as he had been before. A pause, she listened to his heartbeat slow down, then he nodded.

Perfect.

Again, her pace started out slow while she ran her hands up and down his torso, feeling the whip-strong muscles beneath his pale skin, kissing and biting her way down his chest until he writhed. Her hips bounced shallowly, just enough to keep his attention, but she took her time with her lips, sucking purpling hickeys onto his throat, collarbone, and abdomen. Anywhere she could get to, really. She'd never wanted to make someone her own the way she did with him, though she couldn't put a finger on just why. He was an itch she'd been dying to scratch, with all the cock-suredness of the men she surrounded herself with on the outside, and an insane need to please and be pleased on the inside. It was heady, it was addicting. She was in serious trouble.

She thought she heard another muffled "please" come from him, and grinned when she tipped her head up. "Please, what? You want to come?"

He nodded his head vigorously, and she swirled her hips around once more. He shuddered, saliva sliding down from the corner of his mouth. "You want me to take that off you?"

The nodding was more vigorous this time. Her hips picked up speed as she sat back on her haunches, then positioned herself to balance on her feet. It allowed for a better angle, his cock hitting every sweet spot her body knew as she started to go to town. His hands clenched on the shackles, and had they not been lined with leather he might've cut his wrists from holding onto them so hard. Her hands ran absently up her body, and she watched as his knuckles went white once more.

"You want to touch me? Like this?" She cupped her breasts, massaging them and watching as he nodded once more. Never once did his eyes leave her breasts, and she could feel the way that he sucked in his breath when she started tugging on her nipples, moaning louder than strictly necessary, but loving how loud she could be while he was quieted.

"I don't know, maybe I like you like this. Bound, gagged. At my every whim and desire." She whimpered as she felt herself drawing closer, the slow build of pleasure growing exponentially every second she spent atop him. Her pace picked up, his eyes brightened. "C'mon, Pietro. You don't really need your words to show me how badly you want me, do you?"

This time, when he thrust up against her, she didn't stop him, just rode it out with a broken groan that sent shivers down her own spine. The sound of flesh hitting flesh was muffled only by the beating of their hearts and Natasha's throaty groans, her hands abandoning her breasts in favor of running up and down his torso, dragging her nails across his abs, watching the bright red lines pop up seconds afterwards.

She was getting closer faster than she could've predicted, the situation quickening her orgasm. "Pietro, oh, fuck," she moaned, body clenching around his as she rode him in earnest, meeting him thrust for thrust until her breath was sucked from her lungs and her body began to convulse. She pitched forward, catching herself with her arms on either side of him as she trembled and groaned. He fucked her through the aftershocks of his own orgasm, lost in the relief of being able to find his completion, and when she murmured in his ear for him to come, she thought he might actually break the headboard from trying to pull the handcuffs away from them. His heels dug into the mattress, his eyes fluttered shut, and every muscle and vein in his neck stood out as he groaned loudly into the gag. She whimpered happily, kissing his shoulders gently before reaching behind to undo the clasp of the gag.

"You were wonderful for me, you know that?" she purred in his ear, dipping her fingers into his hair. She could hear his jaw crack as he moved it around a couple times. "So wonderful."

"You've got an interesting sense of wonderful," he snarked. She could feel his eyes on her, and grabbed for the key just to the side of them where she'd thrown them before. With nimble, easy fingers she undid the cuffs tossing them away as well. They hit the ground with a clatter, and it was such a relief to have his hands on her, flipping her over with ease. His strength seemed to have a knack of taking her by surprise, and the soft "yip" that left her mouth in shock was a testament to it.

Any semblance of exhaustion he might've had before disappeared, and she grinned up at him. "Want to show me what you think of that?" She arched a brow, her smile taunting. Apparently, being fast had other certain advantages, one she fully intended to exploit as often as possible.
