Ava steps into the woman's locker room in New Avengers tower. She is alone, and she sighs deeply, letting the tension of the mission roll off her shoulders. "God, I need a shower," she mutters to herself, peeling off her tac suit with practiced efficiency. The fabric sticks to her sweat-slicked skin, and she peels it away with a wince, the scent of gunpowder and sweat clinging to her. By the time she's down to her t-shirt and panties, the faint hum of the tower's systems is the only sound, until the door hisses open behind her.
She doesn't even think; her body reacts on instinct, phasing into invisibility before the intruder can spot her. The air around her shimmers faintly as she holds her breath, muscles coiled tight, until Yelena's voice cuts through the silence, dry and amused. "Really, Ava? You gonna ghost me now?"
Ava exhales sharply, materializing with a flicker of static. "Jesus, Yelena," she snaps, pressing a hand to her chest where her heart pounds against her ribs. "You could knock."
Yelena smirks, leaning against the lockers with her arms crossed. "Where's the fun in that?" Her gaze drags lazily over Ava's half-dressed form, lingering on the way the thin cotton of her shirt clings to her curves. "Besides, you're the one who phased like I was some kind of threat."
Ava rolls her eyes, but her cheeks flush under Yelena's scrutiny. "Force of habit," she mutters, reaching for her towel. Yelena's fingers catch her wrist before she can pull away, warm and calloused. "What?"
"You're shaking," Yelena says, softer now, her thumb tracing the pulse point beneath Ava's skin. The contrast between her usual teasing and this sudden tenderness makes Ava's breath hitch.
"Long mission," Ava deflects, twisting free to grab her water bottle from the bench. She cracks it open with more force than necessary, gulping down half of it in one go as she kicks off her panties, the cool liquid doing nothing to douse the heat under her skin. Yelena watches, unblinking, then shrugs off her own vest with deliberate slowness, the fabric pooling at her feet. "What are you doing?" Ava asks, water dripping from her lips.
"Showering," Yelena replies, like it's obvious, stepping out of her leggings with effortless grace. "You should join me."
Ava chokes, sputtering water down her chin. "Fuck... no," she coughs, wiping her mouth with the back of her hand. Yelena just arches a brow, stepping closer until Ava can smell the faint musk of sweat and gun oil clinging to her. "We're adults," Yelena murmurs, fingers toying with the hem of Ava's shirt. "And you're wound tighter than a tripwire." She tugs, the fabric sliding up Ava's torso, her bare stomach exposed. "So?"
Ava exhales, sharp, then nods once. The shower stall is cramped, steam already curling around them as Yelena turns the water on, her body a warm press against Ava's back.
"Tell me if the heat's too much," Yelena murmurs, squeezing soap into her palm. The scent of jasmine blooms thick between them as she works her hands over Ava's shoulders, thumbs digging into the knots there. "Christ, you're like marble," she adds, voice rough with amusement.
Ava shudders, water sluicing down her spine. "Less talking," she grits out, but her hips sway back into Yelena's touch anyway. The other woman laughs low, breath hot against the nape of Ava's neck.
"Make me," Yelena teases, fingers tracing soap-slick circles over Ava's ribs. But when Ava turns, grabbing the soap bottle with a smirk, Yelena lets her, arms raised in surrender. The water darkens Yelena's lashes to gold, beads clinging to her collarbones as Ava drags the washcloth between her shoulder blades.
"You're worse than marble," Ava mutters, kneading at the tension coiled beneath Yelena's skin.
"At least marble doesn't complain." Yelena's chuckle vibrates under her palms.
Then silence, just the hiss of water, the hitch of breath, before Yelena twists, catching Ava's chin. The kiss isn't gentle. It's slick with steam and something sharper, Yelena's teeth catching Ava's lip like a challenge. Ava groans, fingers tightening in wet blonde hair as the shower wall bites into her shoulder blades.
"You talk too much," Ava breathes against her mouth, hips rolling forward, skin catching on skin where Yelena's thigh slots between hers.
Yelena laughs, low and rough, her palms skating down Ava's sides to grip her ass, fingers digging in hard enough to bruise. "Says the woman who phases through walls instead of using doors."
The water turns their movements liquid, every press and shift amplified, breasts sliding together, nipples pebbled tight from heat and friction. Ava arches into it, her gasp lost against Yelena's tongue when clever fingers dip lower, tracing the crease of her thigh with teasing pressure.
"Still wound tight," Yelena murmurs, pulling back just enough to watch Ava's lashes flutter. Her thumb circles, deliberate. "Let me fix that." She than slides her left hand around Ava's hip towards her thighs, fingertips tracing a slow, maddening path along the sensitive crease where muscle meets softness. "Talk to me," Yelena breathes, pressing a kiss beneath Ava's jaw as her fingers dip lower. "Tell me how bad you want it."
Ava's breath hitches, hips jerking forward when Yelena's fingers finally slip inside, two at first, testing the give with a slow twist that has Ava's nails biting into Yelena's shoulders. "Fuck..." The word fractures as Yelena curls her fingers just so, the heel of her palm grinding against Ava's clit in a way that makes her knees buckle. "You're insufferable," Ava gasps, but she's already rocking into the rhythm, water sluicing between their bodies as Yelena's grip tightens on her ass, pulling her closer.
"Insufferable?" Yelena's laugh is dark, wet against Ava's throat as she scissors her fingers wider, relishing the way Ava's thighs clamp around her wrist. "You love it." Then, without warning, she pushes a third finger deep, the stretch sharp enough to wring a ragged cry from Ava's lips, and just like that, she finds the spot, that perfect, hidden angle that makes Ava's back arch off the tiles. "There we go," Yelena purrs, her own breath uneven now as Ava's hips stutter against her hand.
Ava's teeth sink into Yelena's bottom lip to muffle her moan, the taste of copper and steam flooding her mouth as Yelena fucks her harder, faster, fingertips dragging over that sweet, spongy place inside her with every thrust. The water's heat is nothing compared to the fire coiling low in Ava's belly, every nerve alight, until Yelena slows abruptly, her grin wicked. "Not yet," she murmurs, withdrawing her fingers just enough to tease. "Beg for it."
"Fuck you," Ava growls, but her hips chase the loss anyway, her grip on Yelena's shoulders tightening.
Yelena smirks, wiping her fingers clean on Ava's thigh, slow and deliberate. "That's the idea."
Ava surges forward, shoving Yelena against the shower wall hard enough to make the tiles rattle, water sluicing between them as she drops to her knees without ceremony. "Shut up," she snaps, yanking Yelena's hand away before gripping her thighs, forcing them wider with a roughness that makes Yelena gasp.
The first lick is slow, deliberate, Ava's tongue dragging up Yelena's slit with a wet, filthy sound that drowns out the shower's hiss. "Christ..." Yelena's fingers twist in Ava's wet hair, her hips jerking forward as Ava's mouth latches onto her clit, sucking hard before flicking her tongue in rapid, relentless circles.
Yelena's thighs tremble, her breath coming in ragged pants as Ava buries her face deeper, tongue fucking her with a rhythm that's almost punishing, the flat of her tongue pressing firm against that sweet, spongy spot inside. "Fuck, Ava..." Yelena's grip tightens, her hips rolling in time with Ava's thrusts, the water cascading over them both doing nothing to muffle the slick, obscene sounds of Ava's mouth on her.
Ava doesn't let up, her fingers digging into Yelena's ass to hold her steady as she fucks her faster, harder, until Yelena's moans turn fractured, her thighs clamping around Ava's head as she comes with a choked cry, her orgasm pulsing against Ava's tongue in hot, shuddering waves.
Yelena sags against the tiles, her breath coming in ragged gasps as Ava licks her clean, slow and thorough, before rising to her feet with a smirk. "Now who's wound tight?"
Yelena moves forward before Ava can react, her lips crashing against Ava's with a hunger that steals her breath. "You're not done yet," she murmurs against her mouth, fingers tightening around Ava's waist as she spins them, pressing Ava's back into the slick tiles. The water cascades over them, turning their skin slippery, making every touch electric. Yelena hooks Ava's leg around her hip, her own thigh pressing insistently between Ava's, the rough friction of skin on skin drawing a ragged moan from Ava's throat.
"You taste like dark chocolate," Yelena growls, nipping at Ava's lower lip before slipping her tongue back into Ava's mouth, slow and deep, mirroring the rhythm of her hips grinding forward. Their clits brush with each roll, the pressure just shy of maddening, and Ava arches into it, her nails scraping down Yelena's back.
"Fuck... like that," Ava gasps, her voice breaking as Yelena's teeth graze her jaw, the sharp sting blending with the heat coiling low in her belly.
Yelena's grip shifts, one hand sliding beneath Ava's thigh to hike it higher, her other palm flattening against the wall beside Ava's head for balance. The new angle sends a jolt through them both, Yelena's clit rubbing hard against Ava's with every rock of their hips. "You feel that?" Yelena breathes, her voice raw as she grinds down harder, the slick drag between them almost too much. "How wet you are for me?"
Ava's answer is lost in a whimper as Yelena captures her lips again, swallowing her moans as their bodies move in sync, the water sluicing between them doing nothing to dull the heat. The tiles dig into Ava's shoulder blades, the discomfort barely registering over the pleasure building with each desperate thrust, their shared breaths mingling in the steam. Yelena's thigh flexes beneath her, pressing up just right, and Ava's vision whites out for a second, her hips stuttering as she chases the edge.
"Say it," Yelena gasps against her mouth, breaking the kiss with a wet pop, her lips swollen and glistening. She arches her back, driving her hips harder against Ava's, their pussies grinding together in a slick, relentless rhythm that sends water splashing onto the shower floor. "Tell me how bad you want to come."
Ava's fingers tighten in Yelena's hair, her other hand clutching at the slick muscle of Yelena's shoulder as the tension coils impossibly tighter. "God... fuck, I'm close," she chokes out, her voice raw, her thighs trembling as Yelena's clit rubs against hers in perfect, torturous circles.
"Prove it," Yelena taunts, her breath hot against Ava's ear, her hips rolling faster now, their wet skin slapping together in a rhythm that echoes off the tiles. "Let me feel it."
Ava's orgasm crashes over her with a force that whites out her vision, her back arching off the wall as she comes hard, her pussy pulsing against Yelena's in slick, convulsive waves. "Fuck— Yelena—" Her cry fractures, her nails digging crescent moons into Yelena's skin as pleasure ripples through her, electric and unrelenting.
Yelena watches, her lips parted, her own breath ragged as she grinds down harder, chasing her own release. "That's it," she murmurs, her voice rough with want, her fingers tightening around Ava's thigh. "Just like that."
Then she's coming too, her hips stuttering as her clit rubs against Ava's oversensitive flesh, her own moan low and broken as she rides out the aftershocks, their bodies still pressed tight, still moving, still greedy for every last shuddering pulse of pleasure.
The water beats down on them, steam curling around their tangled limbs, their breaths mingling in the humid air as they slump against each other, spent and shaking. Yelena's laugh is breathless, her forehead resting against Ava's. "Told you you were wound tight."
Ava exhales, her fingers tracing idle patterns on Yelena's hip. "Shut up," she mutters, but there's no bite to it, just the slow, satisfied curl of her lips as she nips at Yelena's jaw. "Your turn to beg next time."
Yelena's grin is wicked, her teeth catching Ava's earlobe. "Promises, promises."
Afterwards, skin still damp, Ava towels off with brisk efficiency while Yelena lounges against the lockers, rolling her neck with a satisfied sigh. "You know, I expected more resistance," she muses, tossing her damp hair over one shoulder. "Shield agents usually have better reflexes."
Ava throws the towel at her face. Yelena catches it effortlessly, laughing as Ava turns away, only to freeze when something soft and lacy smacks her bare shoulder. Yelena's bra dangles precariously for a second before sliding down Ava's arm. "You missed the hamper," Yelena calls, already halfway to the door.
Ava glares at the garment, then at Yelena's retreating back, the deliberate sway of her hips, the way her damp tank clings to the curve of her spine. "You're insufferable," she mutters, balling up the bra and hurling it after her. It hits the doorframe with a soft thud just as Yelena steps out.
The blonde pauses, glancing over her shoulder with a smirk that makes Ava's stomach flip. "Keep telling yourself that." Then she's gone, the door swinging shut behind her with a click, leaving Ava standing there, skin still buzzing, the scent of jasmine and sweat lingering like a challenge.
Ava exhales, reaching for her shirt, only to find Yelena's panties tangled in the sleeve. She stares at them, the delicate black fabric absurd against her calloused fingers, then shakes her head with a muttered curse. The woman was a goddamn menace.
And yet, when Ava lifts the fabric to her nose, inhaling the faint musk still clinging to it, her thighs press together almost reflexively. Next time, she thinks, tucking the panties into her pocket with a slow smirk of her own, she'd make Yelena beg for them back.
