The cloudy blanket across National City's sky creates a depressing atmosphere. Lena watches the city skyline through her office window as stray drops of rain land on its surface.
Her new project has sparked controversy among the people of National City and even though she is used to receiving threats on a daily basis, the DEO has informed her that they will send extra backup for her unveiling event tonight. Just to be sure.
That also meant that Supergirl is going to be there. Kara was invited either way, but Lena can't deny that, as much as she enjoys her friend in a dress, she finds the superhero suit even more thrilling. She would never say anything about her desires to Kara of course.
She has always prided herself in being in control of her baser urges and taking suppressants ever since she presented as an omega has helped her a great deal with that. She had her occasional flings, but when it got serious and she had to focus on her studies or business ventures, having no heat was definitely preferable to being tied to your bed to deal with those animalistic instincts and pain.
The one heat she had when she was out of the country once and couldn't get her hands on her medication due to a mix-up with her luggage at the airport has only added to her determination to never slip up ever again.
With that in mind, she throws the pill on her tongue and chases it with a glass of water.
"Mrs Luthor, your car has arrived." Jess informs her over the intercom.
"Thank you, Jess. I'll be down shortly."
The ride was quiet. Lena couldn't quite put her finger on it, but she felt anxious. Her thoughts wander to thelunch she shared with Kara yesterday. The Kryptonian has made great use of the fact that Lena finally knows about her true identity and doesn't miss a chance to stop by on her patrols showering Lena in foods and snacks she gathers along the way. And with along the way she sometimes means Paris or Milan.
It sends a tingling feeling through Lena's chest and the novel sensation adds to her uneasiness. She doesn't realise that her car hit traffic and is no longer moving. Her driver nervously taps with his fingers on the wheel and glances into the mirror at her.
Lena's eyes are glued somewhere outside the window and then everything happens very quickly: the doors lock, the window that separates the driver's cabin rolls up and Lena can hear an ominous hissing sound.
Her instincts kick in and she tries to open the door, but fails. The gas fills her lungs and she starts to cough.
"Motherf-" Lena's vision blurs and the last thing she sees is a tall man approaching her car door.

Kara is humming to herself as she leaves the briefing room at the DEO. She can't wait to be sent to Lena's event today and stand by her side as a protective detail all night long. She loves listening to the young CEO talking business and leaving arrogant men gaping as she easily outsmarts them.
She even did a little detour on her way to work today to get Lena's favourite scones from Dublin. The paper bag in her hand she meets Alex in the med bay.
"Hey there." Kara beams.
"You're awfully cheery today." Alex frowns at the data she's been analysing, not looking up at her sister.
"Thanks?" Kara sits down on a chair and rolls up to Alex' side.
"Does this have anything to do with our assignment today?" Finally, Alex meets Kara's eyes, her eyebrows drawn up as she looks between her sister and the paper bag.
"Maybe?" Kara squeaks.
"Supergirl!" J'onn bursts into the room. "There's a new development. Lena Luthor has been kidnapped."
"WHAT?" Kara jumps up and follows J'onn back into the briefing room.
As it turns out, the threats Lena has received were more serious than anticipated. Opponents of her newest business ventures have gone to great lengths and even abducted family members of Lena's employees to force them to betray her and sell her out. One of her drivers seems to be part of that group.
"We don't have any information on her whereabouts." J'onn informs Kara who has been pacing the length of the room fsiince they entered.
"I have to do something!"
"I can try and reach out to her mentally, but I need an amplifier." He looks at Kara. "Someone with an emotional connection to her." Kara nods and they fly up to the roof to have more silence and no walls obstructing them.
They sit opposite one another and Kara focuses on Lena, which to be honest, is hardly different from what she usually does. Lena is on her mind constantly and she knows what it means, but she also knows that Lena is way out of her league. Yes, she is supergirl, but Lena is a CEO of her own company, all thanks to her intelligence and determination. Without her powers, Kara is only a reporter.
She thinks about those deep green eyes, the dimpled smile, those dark red lips. Kara's got it bad, but she also knows that Lena doesn't date and Kara doesn't know if her heart could handle a casual fling with the most gorgeous person she has ever met, knowing it could never be more.
"I can't focus when your thoughts are, well, this explicit." J'onn informs dryly, but it makes Kara blush nonetheless.
"Sorry."
They sit there in silence for almost an hour before J'onn finally finds Lena. She's in a warehouse at the other end of town and Kara leaps up without a second thought and takes to the sky.
-
Lena returns to consciousness after what could have been hours. She finds herself on a cold hard floor, the room has no windows and everything is dark. She can hear muffled voices from behind walls and she strains her ears to make out any words. It's no use, her head is pounding and her body is aching. She reaches out her hands and tries to feel her surroundings, when suddenly the doors open and a ray of light falls directly on her.
"Mrs. Luthor." A man wearing a mask says. "So nice of you to finally join us."
Lena shields her eyes from the bright light with her hand. She has no idea who she's dealing with, but the man doesn't introduce himself as he signals for her to walk with him.
She walks out the door and quickly realizes that she's been in an empty shipping container inside a warehouse. She barely manages two steps when a masked woman hits her with a blunt object in the stomach.
Lena bends over and curses out in pain.
"How does that feel?!" The woman shouts at her.
The air leaves Lena's lungs and her body is drawing in on itself.
"This is what your new tech does to us. You're castrating alien omegas."
"It's just a precaution." Lena manages to say through the blinding pain. "We don't know how interracial pregnancies affect different species yet."
"So you make sure we can't have any at all, huh?"
Lena wants to argue that they've done several trials and that by her high standards, she feels confident to say that the few side effects they did document are minor and the effects are reversible. But before she can defend her product, another blow hits her and she topples over.
She throws up and even after her stomach is empty, she continues to dry heave and cough.
"Stupid Luthor bitch!" One of the men says. "We know better than to trust your lot."
Lena looks up at all the masks closing in on her. Her vision starts to blur again, but this time she can stay conscious.
"How about we test an interracial pregnancy on you? Would you like that?"
Someone grabs Lena's ankles and pulls her along the floor. A massive figure towers over her and as his hands grip her wrists to keep Lena from fighting him off, she can hear glass shattering in the distance.
People start shouting and grunting and suddenly the assailant on top of her disappears.
"Lena! Are you ok?" Kara's voice is laced with worry, but to Lena's ears it's the sweetest sound. She can feel herself relax immediately and two strong hands touch her and help her sit up.
The red and blue colours of Kara's suit is all Lena can make out, but it makes her smile despite the pain and the adrenaline and she reaches up to brush her fingers along her savior's cheek.
"Kara."
-
Kara takes Lena back to the DEO and Alex is immediately on her to check for injuries. She gives Lena some medication against the pain and after several tests she is relieved to tell her sister, that Lena is going to be fine.
Kara sits next to Lena's bed and holds her hand as she rests. They stay the night at the DEO just to be sure and Kara only leaves her side to get Lena more comfortable clothes.
-
The next day, Kara accompanies Lena to her apartment. She has been adamant about staying by her side.
"I appreciate the rescue, Kara, I really do, but I don't need a babysitter." Lena smiles as Kara walks into her kitchen. The sight of the blonde confidently strutting around her home, knowing her way around, warms her insides and she briefly wonders if she has a slight fever from all the stress.
"I'm not babysitting you." Kara insists. "I'm just making sure my friend is safe and sound."
Lena internally winces at the word friend.
"And I am." Lena walks over to her couch and lets herself fall into the cushions. She's almost never as relaxed as she is when she's around Kara. She's wearing a sweatshirt and yoga pants since those are the only clothes Kara brought her.
Lena inhales deeply and lets out a sigh.
Something's off.
She looks around, but the only thing that is different from the usual is Kara who has joined her on the couch, a bag of chips in her hand.
"Want some?" Kara offers and as she leans towards Lena to hand her the snacks it hits her. Kara smells different. Something about her changed and she doesn't know what it is.
She stares at her and Kara slightly tilts her head, the little crinkle forming between her eyebrows. It reminds Lena of a confused puppy.
"Are you sure you're ok?"
Lena shakes herself out of her stupor. "Are you wearing a new perfume?"
Kara frowns and raises her arm to sniff her armpit. "No, I never wear any perfume. Do I smell bad?"
Lena laughs at her antics, but then another wave hits her and she can feel her thoughts slipping away. All she can focus on is how tight Kara's shirt is. When she lowers her arm Lena follows the way her muscles flex and then she's drawn to her hand, to Kara's slim, long fingers as they manoeuvre some chips into her mouth. Kara chews, swallows and then licks off her fingertips, one at a time and it feels like time has slowed.
Lena's mouth is slightly agape, and she greedily inhales more of Kara's scent.
"Lena?" Kara quietly asks and suddenly Lena realizes that she's been leaning in more and more towards her "friend".
"Kara, you're an alpha, right?" Lena knows the answer, but her brain has slowed down and she needs to verbalize to not forget where her train of thought is headed.
"Yes." Kara says confused. "But on Krypton we genetically repress most of the expression of our secondary gender. We had the matrix for reproduction so it didn't make any sense to risk people running around and ruining the whole concept because of their heat and rut cycles."
"But you do still produce pheromones, don't you?"
Kara's face turns thoughtful. "I don't know. Alex said she was never able to smell any on me. And since I don't go into rut, I don't think they are strong even if I might emit some."
Lena is now super aware of her symptoms. Her heart rate is accelerated, her temperature is increased and her sense of smell is heightened. She must've thrown up her suppressants yesterday and now, for the first time in over 15 years, she'll enter her heat.
"I think I'm going into heat." She frowns at Kara who stares back at her with wide eyes.
"Oh. Do you want me to leave?" Kara says quietly.
"No." Lena replies quickly, surprising herself. "Please stay." She adds.
She won't ask Kara to help her with her heat, but smelling her is the only thing that is keeping her sane at the moment. The thought of Kara leaving almost causes her physical pain.
"Ok, I'll stay." Kara looks at her sternly and it makes Lena squirm a little. "What can I do?"
That's a loaded question. Lena doesn't trust herself to not jump Kara and she would never forgive herself for ruining their friendship in the process.
"I – I'm not sure. I feel like I'm going insane and you make it better." Lena blushes slightly. They both know how this works. Kara knows it's her omega's instincts to seek the company of an alpha.
"Do you want me to hold you?" The suggestion sends sparks through Lena and her stomach starts to flutter. She nods, unsure if her vocal chords might not betray her with a whimper as soon as she uses them.
Kara puts the bag of chips on the table and scoots closer. She loops an arm around Lena's shoulders who in turn leans into Kara's side. The next thing Lena knows, and it consumes her mind completely, is the other hand Kara places on her thigh. Her thumb caresses the top of her leg in soothing circles and the wetness that pools at Lena's centre as a result makes her feel embarrassed. She hopes that Kara's senses don't pick up on her desperate smell, her omega calling out to Kara to continue her ministrations.
"Is this ok?" Kara asks as she rests her cheek on Lena's head. Lena wants to hum in confirmation, but this time it does turn into a whimper and she can feel Kara tense next to her.
The strength of Kara's pheromones intensifies and it is now undeniable that despite the genetic altercations, Kara does produce alpha pheromones. Very potent ones at that.
Lena can't help but nose into Kara's neck where the smell is the strongest. She inhales greedily, her lips almost brushing the skin there.
A low growl sends shivers through her body and as she reluctantly leans back she locks eyes with Kara. Her pupils are blown and the cornflower blue is nothing more but a slim halo around black pools.
"Lena." Kara's voice is low and gravelly, and Lena finally decides to throw caution to the wind.
She leans in and Kara meets her halfway in a warm, soft kiss. Sparks run down Lena's spine and she starts to slightly shake. They stay connected for a moment and when Lena leans back she needs Kara to know that this is not just her heat. She needs to reassure soft and kind Kara, that this is not just a physical fling.
"I've wanted to do this for a while now." She whispers into the blonde's mouth and Kara's response is to dive back in with more need, more passion and their lips move against each other in desperation.
Kara repositions them so that Lena reclines and Kara is on top of her. Their lips never disconnect and when Lena licks along Kara's lower lip she is immediately granted entrance. The kiss turns filthy and Lena moans loudly into Kara's mouth who greedily swallows every sound.
Lena's legs bracket Kara's hips and they grind against one another in fluid motions. Lena's panties are already ruined and the liquid starts to make her feel uncomfortable. Her clothes bother her and she starts pulling at her shirt. Kara gets the hint and without any hesitation aids her in her venture to rid herself of the offending clothing.
The sweater lands somewhere behind the couch and Kara wastes no time to undo her bra. Lena lays under her with her chest bare and Kara stops to take in the sight in front of her. Her eyes roam across Lena's pale breasts and her hands come up to gently cup them. Lena arches to press them further into Kara's hands who diligently starts to massage them.
Lena grinds harder into Kara's centre and stops as she feels the hard bulge moving against her to rip another filthy moan from her lips. The lack of movement is broken by Kara who seems too far gone by now to stop herself and she dives down to lavish Lena's chest with kisses. The trail of saliva she leaves cools Lena's burning skin and she starts to squirm more and more as Kara descends down towards her pants.
"Take them off. Take it all off." Lena's eyes are closed, lost in the sensations of Kara's lips on her skin. She can feel a hint of air brushing over her and when she opens her eyes she sees Kara back on top of her, naked in all her glory. She takes in the firm body, her round breasts, the flat stomach and the big, hard cock standing up against her belly. The tip is shining from the precum that slowly starts to drip down the shaft and Lena can't help but whimper at the sight.
"Please, Kara." She's never vocally begged for anyone or anything. And it does the trick, Kara's hands grab the seam of her yoga pants and simultaneously pull down her panties. She discards the clothing and her hands move down to Lena's knees, over her thighs and land on her hips.
"You are so beautiful." The compliment makes Lena both smile and blush.
"I'm all yours." Lena confesses and Kara's face contorts and with a pained groan she dives down towards Lena's neck and kisses and sucks at her skin there.
Lena gasps and swings her legs around Kara's hips to pull her closer. She can feel the hard shaft move through her wet slit. The tip of Kara's cock pushes against her clit on every upward move and they fall into a fluid rhythm. Both their breaths start to come in short intervals and their mingled fluids cause obscene sounds that echo through Lena's apartment.
"Kara." Lena breathily moans. She kisses up Lena's neck until her mouth is right next to her ear. "What do you need?"
The question draws a desperate sound out of Lena and her hips buck involuntarily. Her insides are pulsing and clenching around nothing and the ache to be filled is almost unbearable at this point.
"Inside. Kara, please." Kara's breath hitches and she falters briefly.
"I don't have any condoms with me." She confesses, but Lena is too far gone to care. In fact, she can't wait to feel Kara raw inside of her.
"It's ok, we'll deal with it after."
"You sure?" Lena nods and reaches between them to align Kara with herself. Kara groans and slightly bucks at the contact, causing the tip of her cock to slide in.
They both moan at the feeling and Lena's muscles contract to draw Kara in further.
She can't resist the pull and gently moves into Lena until she bottoms out. They stay like this for a moment, Kara breathing heavily into Lena's neck. The feeling of being filled so fully satiates Lena's omega and she revels in the relieve of having Kara inside of her, of being so close that there is no beginning and no end. Then her desire flames up again, letting her know that it still isn't enough.
"Fuck me, Kara, I need you."
Kara's voice is a deep rumble and she starts a slow back and forth movement. Her body is strained and it seems to take a lot of self-control to no just rut into Lena.
Lena's nails rake over the unbreakable skin of Kara's back and she arches at the delicious contact every time Kara's broad tip passes her inner sweet spot.
Her breathy moans spur Kara on and she gains more confidence. Her hands pin down Lena's hips with a hard grip as she speeds up. Her thrusts turn harder and Lena gasps each time Kara bottoms out.
"Yes, Kara, yes."
Kara's lips close around her neck and she starts to suck rhytmically timed with her lunges. Lena claws more desperately at Kara, trying to pull her closer, but there is no space between them.
"Lena." Kara growls and Lena can feel herself racing towards the edge. Her muscles pulse around Kara's thick shaft which in turn sends the blonde into a frenzy. The sounds of their bodies meeting with their tangled fluids covering most of Lena's inner thighs is almost deafening to her.
"Come for me, Lena." Kara demands and as if she had no choice but to obey, Lena convulses and her whole body goes rigid as her orgasm washes over her.
Kara doesn't falter. She relentlessly moves into Lena like a woman possessed all the way through her orgasm.
"Karaaaa." It's nothing more than a breath and Kara kisses along her neck, her hands moving up along Lena's body to hug her tight.
"Mine." She whispers into Lena's ear and the word triggers a carnal response in Lena.
She wants Kara to mean it, she wants her to claim her.
"Yours." She says and Kara bites into her neck, not hard enough to break skin, but it is enough to send Lena into a second, more intense orgasm. Kara follows her and with one final buck, her throbbing cock shoots ropes of seed into Lena's womb.
Kara's orgasm has her bucking again and again, each time pouring more of her release into Lena. She can feel her belly starting to strain from the sheer amount of Kara's release.
"Yes, yes, yes." Lena hears herself say like a prayer, no longer in control over any part of her body. She goes limb as Kara's orgasm tapers off.
She lays on top of Lena like a blanket, seemingly spent and soft. Kara nuzzles Lena's neck where she suspects a dark love bite is already forming.
"Lena." Kara says again and Lena's hands lovingly roam over the expanse of the muscular back. That's when she feels Kara stiffen.
The Kryptonian pulls back and out of her, causing Lena to whimper at the loss of contact both form both above and inside.
Kara looks down at herself in shock and Lena follows her eyeline.
She can't believe it.
The base of Kara's cock begins to swell slightly, a telltale sign of an alpha entering rut.
"That can't be." Kara breathily says as she touches the swollen part of her knot forming, causing her cock to twitch at the stimulation.
"Kara, is that your knot? Are you entering rut?"
Lena pushes herself onto her elbows, causing the excess of Kara's seed to slowly flow out of her. For a moment they are both entranced by the sight of it.
And then Kara's instincts take over. With the tip of her cock she gathers her cum and gently pushes it back inside. The move makes Lena's eyes roll to the back of her head and she falls back onto the couch.
"I heard of it sometimes happening." Kara says as she moves back on top of Lena. "When two souls meet that are meant for each other, the pheromones of a true mate can block the genetic repressor."
Lena understands only half of what Kara is saying.
One reason is that she is not sure what a true mate is, but she knows enough about genetics to understand how repressors work and that hormones can regulate genetic expression. The other reason why her brain cannot fully process the new information is because Kara starts to move inside of her again and despite the fact that she just came, twice, she is right there at the edge again.
"I don't care how, I'm just happy that you can." Lena moans.
Kara bottoms out and stays inside. She looks at Lena, a shimmer at the edge of her eyes indicating that there is more to it.
"Lena, a true mate is like a soulmate."
They hold each other's gaze for a moment.
"Well, then I'm glad it's you." Lena gently caresses Kara's cheek and they meet for a passionate kiss. Lena doesn't believe in soulmates, she's too pragmatic for that, but she believes in biological compatibility.
"You don't have to if you don't want to, but –" Lena doesn't know how to ask for it. She couldn't bare the thought of Kara ever wanting to be with someone else. Picturing Kara's bite on someone else's neck sends unexpected tears into her eyes and she tries to blink them away.
"I won't mark you, Lena. Unless – ". As if Kara could sense where Lena's mind went she kindly offers her what she truly wants. Lena nods, a stray tear escaping her eyes despite her best efforts to contain them.
"I've always been yours. Be my mate." The confession hangs between them and Kara stares at her for a second before a warm smile spreads across her face.
"I feel the same way."
They kiss again, soft and full of emotion. The pulsing motion around Kara's cock sends her back into a grinding movement and the groan that escapes Kara breaks the kiss briefly. Lena strains her neck to recapture Kara's lips in a more heated kiss and quickly their love making turns into quick rutting.
The need for air makes it impossible to maintain any kiss and Lena gasps into Kara's mouth.
"Flip me around." Lena orders and Kara instantly puts her hands on Lena's hips to help her present. As soon as Lena is on her knees Kara buries herself inside of her again and her hands grip Lena's ass tightly.
The quick and harsh thrusts drive Lena's upper body into the couch and the deeper Kara pushes herself, the more of her cum is pushed out and runs down Lena's thighs.
The sight seems to vex Kara and her growl causes Lena to push herself further down and her ass further up. It doesn't scare her, she trusts Kara with her life.
Kara grabs Lena around her hip to pull her tightly against herself as her thrusts become less deep but quicker. She leans forward and then Lena is laying flat on her stomach, Kara pressed into her back and bucking into her with determination.
Soon Kara doesn't go as deep anymore and Lena can feel the thick base of Kara's cock push between her lips. With every thrust she can feel them stretch around Kara's shaft a little further and the feeling sends her into another sphere.
Her eyes roll back and her lower body begins to tingle. The side of her neck almost feels itchy and she no longer wants, but needs Kara to claim her.
"Do it Kara, claim me. Make me yours."
Kara whimpers as her arms snake around Lena. One lands on her belly and presses down towards where she is buried deep, the other grabs one of Lena's breasts and squeezes tight. Her mouth traces along Lena's shoulder towards her neck.
Her mouth closes around the spot where an alpha leaves their mark and she starts to push into Lena with more force. She bucks into Lena's ass and Lena moans loudly at the stretch.
"Mine." Kara whispers into Lena's skin as she bites down and breaks skin.
The feeling sends Lena into a rigid state and she can feel herself opening up. Kara pulls with her hands and pushes with her hips and her knot slides into Lena's pussy and takes hold as the first ropes of cum shoot into Lena.
Her orgasm crashes into her like a wave. Lena silently screams out in pleasure and Kara growls into her neck. The vibrations travel through Lena's body extending her orgasm.
Kara starts to slightly move, rubbing her knot against Lena's inner walls. It prolongs Kara's release and with every throb of her cock, another load shoots against Lena's cervix. Lena isn't sure if it triggers another or whether she has one long lasting orgasm, but she gasps for air as Kara starts to rub her belly. It starts to strain from all the seed Kara deposits inside of her and finally, after what feels like an eternity, Kara seems to come down.
They both pant, Kara's breath is hot against Lena's neck. Lena can feel gentle kisses tracing up along her neck towards her jaw and Kara seems to murmur something against her skin what she can only guess is Kryptonese.
"Kara." She happily murmurs as she drifts off.
"Rest, my Lena."
Kara wraps Lena up in her arms, both still tied and turns them to lay on their sides as she as well gives in to exhaustion.
