Chapter Text
Clarke expertly fastens the silk ropes with a column tie. The bondage workshop Raven made her attend last summer does come in handy once in a while. She hops off the chair with one last flourish and Lexa writhes, hanging from the ceiling by her wrists. Her toes are barely brushing the carpet – this is cruel, Clarke realizes, as it will surely lead to chafing and soreness in her mate’s shoulders, but if everything goes to plan, Lexa won’t be tied up very long.
Clarke smiles in satisfaction at the sight of her mate’s predicament. Lexa is naked – gloriously naked. Her lithe and athletic body is the epitome of alpha strength. She has strong shoulders and arms, long, toned legs and visible abs that shift beneath Clarke’s fingers when the blonde touches the smooth skin of her stomach. Clarke always found Lexa to be the more alpha out of the two of them, even though it was hard to admit. Their friends also share that opinion. They don’t know that in the privacy of their bedroom, Lexa submits to her more often than not.
Clarke rounds the offered body, eyes roving tantalizing planes of soft flesh and hard muscle and wondering where to begin. The brunette wriggles a little, twisting to keep track of Clarke’s whereabouts.
‘Hush, you’re going to twist the ropes.’ Clarke tsks with an amused smile.
When Lexa stills with a huff, Clarke rewards her with a kiss between her shoulder blades. She slides her hands up the sides of Lexa’s body, feeling each set of ribs under her fingertips. She relaxes at Clarke’s touch and Clarke almost feels like being soft… almost.
Her hands trail down to Lexa’s hips, to the flare of her perfect ass. Clarke traces elliptical patterns on the soft round flesh for a minute just to watch her mate shiver and goose bumps rise on her skin. She kneels, her face now level with Lexa’s ass, and rakes her nails in circles across her cheeks until olive skin turns pink.
‘Eyes up front, pretty girl.’ She quips when Lexa cranes her neck to watch her.
Warmth emanates from her skin. Clarke leans in to replace her fingers with her lips, kisses growing less and less chaste the closer she gets to Lexa’s center. She spreads her cheeks and hums when she sees the tight ring of muscles.
It took a lot of exploring from both of them before they were able to truly embrace this side of their sexuality. Growing up, alphas are told they are meant to penetrate, not the other way around. Once they tried it the first time though, it took very little convincing for them to do it again – Lexa especially loved it.
Clarke coats two of her fingers in lube before teasing around the rim of Lexa’ entrance, her mate going limp as soon as she makes contact. Clarke smirks even though Lexa can’t see her. She rests her face against Lexa’s ass cheek, her own fingers pushing against the flexing little hole until it gives. Lexa curses breathily.
‘So tight, baby…’ Clarke hums in-between kisses to heated skin.
Warm muscles grip her fingers, sucking her in. She gives a few slow pumps before pulling out.
‘Clarke.’ The brunette growls impatiently when Clarke steps away for a few seconds.
‘I’m here.’
She returns with a plug – Lexa’s favorite. It goes in easily and Clarke just loves the look of it when it is seated deep inside her mate’s ass. Clarke inspects her work - the red jewel looks so flattering against her skin tone.
‘That’s my pretty girl.’ Clarke praises with a satisfied pat to Lexa’s hip before standing back up to face her.
Lexa is struggling, body arched like a bow so her toes can reach the floor just enough to relieve her wrists and shoulders. A thin sheen of sweat has broken out across her forehead and in the hollow of her throat, and her blown pupils lag behind Clarke’s movements, already a little dazed. Clarke pauses for a second, checking in.
‘What’s your color?’
‘Green.’ Lexa croaks.
‘Good.’
Clarke refocuses her attention elsewhere, on the round swells of Lexa’s breasts. She roughly pinches one of her nipples before leaning in to envelop it between her lips, soothing the sharp sting with her tongue. The brunette is panting with the effort it takes to keep her toes in contact with the floor despite the stimulation. Clarke hums around the delicate brown peak, applying suction while her left hand plays with the other breast. She drives her mate wild with it, constantly switching between teeth and tongue, rough and soft.
Lexa’s hisses and whines are music to her ears. She releases her nipple with a loud pop. Lexa watches her expectantly, knitted brows pleading Clarke to take pity on her.
‘Well, what have we got here?’ Clarke lets her eyes drop lower, past taut abdominal muscles, to her mate’s erection. Lexa’s full six inches – a rare feat for a female alpha- stand at attention against her lower stomach. ‘Such a pretty cock, nice and hard for me.’ She purrs, wrapping her hand around the thick length.
It has a really nice curve to it, which Clarke has gotten very well acquainted with on occasion. A shiver runs up her spine and she almost ruins the whole scene wishing she could just take Lexa into her mouth instead. Clarke swipes her thumb across the dripping head and Lexa’s hips jerk forward. She’s warm and thick, the familiar veins throbbing against Clarke’s palm like a beating heart – which technically isn’t so far from the truth, in this moment. Clarke feels her own cock swell in her boxers.
‘Shit baby,’ Clarke chuckles. ‘You’re so desperate.’
Lexa’s hips thrust into Clarke’s loose grip. She’s fucking her hand like a needy pup in her first rut, the aching red head dripping steadily onto the blonde’s fingers. Clarke squeezes to add more friction. Lexa whines, eyes screwed shut and mouth hanging open as she chases the feeling and takes whatever small relief Clarke will grant her. The V of her hips clenches with each forward jerk.
Clarke withdraws her hand and Lexa protests. She pouts at being denied, clouded eyes dropping to her painful predicament.
‘Clarke, I’m not kidding, there’s only so much I can-‘ Lexa’s shaky voice dies in her throat when Clarke swipes her sticky fingers across Lexa’s plump bottom lip. She leans in to kiss her, tongue and teeth and all, tasting her mate’s essence in the kiss.
‘You’ll take what I give you.’
Lexa’s lips chase hers after Clarke pulls away but the blonde has her sights set on Lexa’s ass. She slides her hand along the slope of her mate’s back, down the gracious curve of her spine and between her ass cheeks, feeling for the plug. She eases it out of her slowly, fighting the grip of her tight muscles holding onto the toy. Lexa’s breath catches when it pops out.
‘Do you feel empty now, baby? Clarke smirks upon seeing the brunette’s unfocused gaze. ‘Gonna make you feel full again.’
She unties the knots that secure Lexa’s wrists to the ceiling and the brunette’s knees buckle when the soles of her feet finally find the carpet. Clarke takes off her own boxers, throwing them to the other side of the bedroom – they’ll probably laugh tomorrow morning when she or Lexa finds them hanging from the door handle or something like that. The lube feels cold on her dick. She’s overheating from being so fucking turned on.
‘Hands and knees.’ She commands, pushing on Lexa’s upper back until she’s bent over the edge of the bed and heavily panting.
Clarke takes a second to appreciate the view. Lexa’s cock is still hard and dripping steadily onto the sheets. She lines herself up and pushes forward. Lexa groans, dropping her head against the mattress as Clarke gives a few shallow thrusts before bottoming out.
The heat of Lexa’s ass is stifling, her body holding Clarke’s cock in a deliciously tight grip. Clarke rolls her hips slowly at first to make sure her mate feels every ridge and vein, every inch of her. Soon, her instincts take over. It’s not quite like being with an omega – there is no rut-induced frenzy that drives her to claim and breed – but Lexa’s pheromones have a similar effect on her. It’s sandalwood and vanilla and vetiver and pure, all-consuming lust that calls to her wolf, begging her to take her.
Clarke rears back before pushing in with a little more force and Lexa curses, high and breathy. The slap of skin on skin sends Clarke reeling. She digs her fingers in the flesh of her mate’s hips, rutting against Lexa’s ass in a frenzy.
The brunette grunts and claws at the bedsheets. Her shoulders brace for every impact and Clarke drapes herself across Lexa’s back to trace each tensed muscle with her tongue.
‘Yes, pretty girl.’ Clarke growls when she reaches Lexa’s neck. She noses at the mark at her pulse point, drags her teeth against the scar. ‘You take me so well baby. Such a good alpha bitch.’
Lexa clenches at the dirty praise murmured hotly into her ear. She pushes back against each thrust, and Clarke reels her wolf in, not wanting to go too far – her knot has started to form at the base of her cock, making her thrusts more shallow.
It’s a struggle; Lexa does not seem too keen on slowing down and it takes a lot of effort from Clarke not to give into her instincts.
‘Your knot, Clarke-‘
‘I know, don’t worry I won’t.’
‘Do it. Knot me.’ Lexa groans against the mattress after a few hesitating seconds.
Her voice is shaky from how keyed up she is, and Clarke is not sure she heard correctly. She slows down, panting, and forgets to be dominant.’
‘What?’
‘I want your knot. Please!’
Lexa is fucking begging her, and Clarke doesn’t know what to do. Alphas don’t knot each other. It’s been engrained into their brains from a very young age that alphas are not even supposed to be together in the first place. Knotting is said to be painful and degrading to anyone who isn’t an omega. Lexa has never knotted Clarke and has never let Clarke knot her before – it’s a line they haven’t crossed yet.
‘A-are you sure?’ Clarke softens for her mate. This is serious now. She can’t let their pheromones get in the way of good judgment
‘Please.’ Lexa repeats.
Her upper body sags against the mattress and Clarke crosses her mate’s dark green gaze. Her eyes are clouded over but they’re filled with trust and need.
‘You have to relax, yeah?’
Lexa exhales a shaky sigh, elbows braced against the mattress and spine arched just so. Clarke rocks forward slowly. The swell of her knot bumps against Lexa’s entrance but she doesn’t push in yet. She wants Lexa to feel her, want her to get comfortable first with the extra stretch.
It’s slow, torturously slow and it’s not getting anywhere, as the knot won’t go in without a little force.
‘Just do it, Clarke.’ Lexa whines impatiently after a long minute. ‘I’m green.’
Clarke rears back and pushes back in with a forceful jerk of her hips. Her knot pops in and Lexa lets out a pained hiss, biting her knuckles to stifle a groan.
It’s snug. Such a wonderfully tight fit, and Clarke is spending herself in copious amounts inside of her mate before she even realizes it, hunched against Lexa’s back.
‘Fuck!’
They’re tied, and Clarke doesn’t dare to fucking move an inch, but she so desperately wants to. Stars dance behind her eyelids as she keeps coming, but Lexa’s breathing is ragged and heavy.
‘Are you okay? Hold on, let me just-‘
She wraps an arm around Lexa’s waist, keeping her close, and moves them carefully up the bed in a spooning position. The brunette is sweaty, eyes half-lidded and tense. Clarke is not sure whether she’s still in pain or just on the brink of coming too – her cock is still rock hard, twitching against her stomach. Clarke wraps her hand around it and strokes a few times, twisting expertly when she reaches her tip just the way Lexa likes it.
She comes too with a strangled groan, spurts landing on the bed sheets and on Clarke’s hand. Her whole body clenches and unclenches around Clarke’s cock, milking the last weak slips from her. For a while, they both just lay there, still tied and entwined in each other, panting and sweaty in the stuffy bedroom.
‘Are you okay?’ Clarke asks again when she realizes Lexa didn’t answer her the first time.
‘It hurt at first but I’m okay now.’ Lexa smiles tiredly, burrowing into the nook of Clarke’s hips.
‘You did so good, I’m so proud of you.’ Clarke praises in-between kisses to her mate’s temple. Lexa lets out a contented sigh.
‘Love you so much.’ She mumbles, eyes fluttering shut as she gives in to her exhaustion.
