Chapter Text

The nearly fluorescent lights of the laboratory highlight the emptiness of all of the vials in front of the young woman. She sighs in exasperation as she runs through all of the possibilities of what this could mean. This was a problem so far out of the realm of possibility to her that it did not seem necessary to come up with back up plans. Now, she was regretting the lack of planning she normally put into everything else in her life.
Who did she need to call first? Her girlfriend-- who this information would affect the most. Or the person who could probably help her the most with the consequences of this misstep. Lena picks up her phone, taking a step back from her vials and making her way to her computer, clearly needing to make an order for new supplies and components. After a few rings, the other line is finally connected.
“What's up?” Alex asks quickly. It is the middle of the work day, Lena hadn't fully expected the other woman to pick up at all.
“I have a Supergirl problem.” Lena says, not trying to waste Alex’s time. She was sure the new director of the DEO had more important things to do than small talk. Alex takes the comment in stride, knowing Lena had used the proper name for her sister only due to it being work hours and the line possibly being overheard. Alex makes her way to a side hallway before responding,
“Details?”
“I… lost track of the suppressants." Lena admits hesitantly. ‘Losing track’ of something so crucial to Supergirl's performance was something Lena was explicitly paid NOT to do.
“Lost track of?” Alex clarifies, finally finding an empty conference room to dip into.
“I thought I had enough for the next cycle but I miscalculated.” Alex’s sigh on the other end of the phone is audible. Lena nods at the sigh, being similarly frustrated in herself for this mistake as she continues to order the needed parts for a new batch. “Ordering enough for a new batch shouldn't take long,” Lena continues before Alex can express more of her disappointment. “And I can have the next round ready soon, it shouldn't be a big deal.” Lena puts in the order before turning to her calendar to confirm the information she knew before all of this started.
“I will miss her next cycle though.” Lena says.
“When is she starting?”
“Within the week.” Alex laughs at this response. Not only would this be a problem for Supergirl, but this misstep would affect the entire DEO. Alex walks out of the conference room to find the nearest screen showing Supergirl's location-- 50 thousand feet in the air, over Mexico.
“The three of us will come up with a plan when she’s back. I'll meet you at HQ.” Alex uses the codename for Lena’s apartment before hanging up, keeping an eye on Kara’s flight patterns and her comms with the rest of her navigation team. She hadn’t started the mission looking for anything out of the ordinary but now? She was listening closely to everything her sister said while coming up with a plan for the DEO, Kara and Lena.

Later that night, the three women sat in Lena's spacious living room. The humans had just broken into their rice bowls while Kara was on her third box of potstickers, reminding herself to leave the fourth box for her sister and girlfriend. With her cycle starting so soon, she always had to force herself to share whatever she had. Once Kara put down her box and started to open her rice bowl, Lena and Alex shared a knowing look with each other before starting,
“Hey, Kara.” Lena started, figuring she should take the lead seeing as it was her mistake.
“Yes?” Kara asks, opening her plastic fork with ease.
“I fucked up. I don't have your next rounds of suppressants." Alex’s eyes quickly move to Kara. The super hero calmly nods before responding,
“I can probably miss one dose. Nothing I can't handle.” Alex can’t help the small snort that comes out. This draws the young couples’ attention.
“What?” Kara asks defensively, reminding Alex of the teenager she had grown up with. The teenager that she watched go through cycle after cycle before Alex had the resources and knowledge to make her first round of suppressants. The teenager who would curl up in a ball, unable to walk with how much she needed release. The young adult who would leave wet and sticky toys all over the floor for days with no care as to who saw.
“You won't be able to move when it starts. Much less fly around the city like normal.”
“That was when I was a kid. I have much more control now.”
“What happens on your cycle?” Lena cuts between the bickering siblings to ask. By the time Lena and Kara had gotten together, the Kryptonian had been on a strict schedule of suppressants for years. Alex had tailored the concoction to near perfection, only making Kara present for a few hours during her normal cycle. Once Lena had gotten close enough to them, she had dialed in the suppressant so that Kara felt no different than any other day. It had been years since Kara had felt a full heat cycle.
“She goes insane.” Alex butts in, her mind filling with memories of sharing a house with a young alien in heat. “She gets angry and moody and makes a mess everywhere and eats more than she already does.” Lena’s eyebrows raise at this. Her girlfriend already ate more than four humans could, she couldn't imagine how her adoptive mother could have fed her growing up.
“No no.” Kara stops her sister, putting down the last couple bites of her rice bowl before fully explaining, “Kryptonians have an Alpha and Omega system. Alpha's jobs are to impregnate at all cost, Omega's jobs are to carry and birth the new generations. I am presented as an Alpha, so when I go in heat all my body and mind should be focused on is impregnating an Omega to further my species. When an Alpha can't do that it does result in mood swings,” Kara looks at Alex now, watching her sister nod as an ‘I told you so’. “But now that I'm an adult, I can tell the difference between instinct and logic.” Alex rolls her eyes at this, closing the plastic bowl her rice bowl had been in and reaching for the last box of potstickers. Lena takes one for herself and takes a bite before asking,
“So the mess you left all over the house was--”
“She had cum in tissues all over the floor.” Alex says, channeling the annoyance she felt twelve years ago like it had just happened yesterday. Lena nods as she finishes her potsticker then puts her hand on Kara’s thigh.
“We’ll be sure to have morning and after work sex to get it out of your system.” Alex makes a faux noise of disgust at the couple in front of her, making a show of rolling her eyes at them. The three laugh at this as they finish their dinner, catching each other up on their individual days and upcoming plans.

Chapter Text

Two days had gone by since that conversation. The three had begun to think that maybe the years of suppressants had made Kara’s cycle dampen. Either that, or Kara really could keep instinct and logic separate. Kara had spent the last few nights at Lena’s place as usual-- she hadn't spent nights at her own place in months unless Lena was out of town. The two had spent the last few nights like usual: dinner, movies and cuddling, a light makeout session between streaming ads. Nothing out of the ordinary. Lena felt like she had been overly stressed for this ‘heat cycle’ nonsense.
Until her phone begins to buzz on her desk, the screen lighting up with the DEO director’s name. The two never called each other casually in the middle of a work day.
“How’s Supergirl?” Lena asks, knowing there's no other update to give at the moment. She had been signed on only to monitor the kryptonian.
“Grounded, we have Superman finishing her flight paths until further notice.”
“On leave?”
“Until we have control of the situation, yes. I'll deliver supplies to HQ ASAP.” And with that, the line is cut. Lena quickly makes work of cleaning her office. As she begins carefully but quickly moving papers from their sprawled positions on the desk into a folder, her phone chimes. A small alarm that signals the opening and closing of any ways into her apartment. Normally she ignores the alarm considering it's always either her or Kara leaving before her in the mornings. She opens her phone quickly and turns on the cameras. The blurry image shows her girlfriend slowly gathering dirty clothes from off the floor and blankets from the couch. The blonde moved slower than Lena had ever seen from her and hunched like she was either trying to sneak, or maybe she was injured.
Lena puts her phone down as she packs the last of her things, watching the camera from the corner of her eye. As she picks up her purse and slings her jacket over her forearm she watches Kara lay in a pile of blankets, dirty clothes and old towels on their bed. Lena switches over to her phone and dials Kara as she closes her lab door behind her, entering the code to lock it. She listens to the other line ring as she walks to the elevator, pushing the button and watches the doors close. Still, no answer. She opens the camera again to see Kara still in bed-- face up, now fully naked, hands over her eyes, Lena’s underwear in her mouth, cock fully at attention. Lena licks her lips at the picture in front of her. The temptation to take a screenshot of Kara like this was strong. The woman was normally so composed and modest, this was a side of her girlfriend that Lena hadn't even imagined.
Lena walks out the elevator and quickly finds her car. Once the phone is hooked up to the bluetooth, Lena turns on the two way microphone connected to the security system.
“Kara?” Lena says gently, pulling out of the parking garage swiftly.
“Fuck, Lena.” Kara grunts. She sounds like she's straining against the tightest binding she's ever encountered. Fighting against kryptonite itself where she lies.
“I'm on my way home, Darling.” Lena tries her best to soothe.
“I'm ok. You should stay at work.” She sounds as though she ran a marathon.
“You're going through heat. Let me help you.”
“I don't need help.”
“You're cumming just from having my panties in your mouth. You're not ok.” This sends a growl through the microphone. Lena would have sworn a sound like that only came from wolves or bears. She couldn't imagine that her sweet, careful girlfriend of 3 years could make a sound like that. Especially not directed towards her.
“Fuck, don't talk like that, Lena.” Before Lena could respond, her phone began to chime with Alex’s name popping up on her dashboard screen.
“Sit tight darling, I'll take care of you soon.” She hangs up without another word before swiftly switching over to Alex’s call.
“I'm on my way out of the DEO, I’ll meet you at yours with Kara supplies.” Alex rushes out.
“Ill meet you there. What happened today, by the way?”
“She couldn't get into her suit at first without…” The pause is dramatic before she settles on “some dramatic tenting.” Lena has to stop herself from laughing before Alex continues. “She tried to say she could hide it but she couldn't keep her hands off her crotch long enough to walk out of her changing room.” the heavy sound of a car door slams in the background before Alex continues, “I still had to fight her to go home after she almost came in her suit. It hit her hard and fast.” Lena sighs, both in amusement and nervousness at what she might walk into as she pulls into the driveway of her secluded property.
“I just got home. Call me when you get here.”
“Good luck.” Alex says before hanging up the call. Lena immediately turns her phone ringer up before grabbing her bag from the passenger seat and making her way into the house.

Lena walks in as quietly as possible, hoping that her girlfriend would be too preoccupied with other things to use her super hearing. As she sets her bag down on the kitchen floor she hears a growl come from deeper into the house. A sound that would make her think an animal is in the house if she didn't know the state of her girlfriend right now. Lena takes off her shoes before walking to the carpeted stairs up to her bedroom. The closer she gets to her bedroom at the top of the stairs, the louder the panting and whines get. As Lena enters the doorway of the large bedroom, she stops at the sight of Kara on her knees, one hand holding panties to her face, the other resting on the base of her semi hard cock. Her blonde locks a mess on her head, and her normally even pale skin is now red and blotchy. This woman in front of her is not the girl of steel known to the world. This is an Alpha, desperate to make as many pups as possible.
“I’m sorry.” Kara whines out, moving the underwear off of her mouth just long enough to say these two words. “I’ll leave as soon as I can.” She mumbles through the cloth this time.
“Take your time, Kara. Do what you need to do.” Lena says, not moving from the doorway, wanting to give Kara space and any privacy she may need. Before Lena can ask what to do next her eyes move to the visibly straightening member in Kara’s hand and the underwear in her hand swiftly moving into her mouth. As much as it pained her to see the woman so visibly uncomfortable and out of control, she had to admit it also turned her on to see the way she stroked her length to her smell. Kara knew Lena couldn't get pregnant from her but that didn't stop her Alpha instincts from latching on to Lena as her own. Before Lena could think further about what that meant for their relationship, a loud ring came from her pocket. She quickly walked away from the bedroom and silenced her phone. Without answering, Lena opens her front door to see Alex standing with several grocery bags in hand.
“What kind of supplies do we need?” Lena asks, eyebrows pinched in worry at the amount of stuff the older Danvers had in hand. Alex follows Lena into the house and into the kitchen where she finally sets down the bags.
“For Kara- pork dumplings and ice cream. For you- protein shakes, yogurt, bananas, magnesium and I bought a few UTI kits just in case.” Once Alex had finished putting the things that needed to go into the refrigerator in their spots and the various medicine on the counter, she took the backpack she had been wearing off of her back. The sound of Alex unzipping the backpack was mixed with the loud moan from upstairs. Lena had meant to close the bedroom door before Alex had gotten here. She felt her face heat up in embarrassment for her girlfriend as she made eye contact with the woman in front of her. Alex just shakes her head before reaching into the backpack.
“I won't go through everything but there's lots of lube,” Alex takes out a small bottle of ‘super slick water- based lube’, “and condoms, not sure if you guys need that.” Alex continues to rummage before settling on what to grab. She pulls out a large black cylinder with tan silicone poking out of the top. “If you need a break from her this should keep her busy for a while.” Lena hadn't considered herself a prudish person, and rarely was she ever embarrassed by sex, but between this conversation and the steady whines coming from upstairs, Lena feels her cheeks turn redder and redder with every passing second.
“Ill drop off food after work. I don't want to be back in this house until that,” Alex points to the stairs admitting all types of animalistic noises, “is over.” Lena nods at this, then watches Alex move to the doorway and walk out.

Chapter Text

As soon as the door is closed, Lena opens one of the six bags of dumplings Alex left and begins to warm them up. By the time she fills up two water bottles and sets out two bowls-- one regular size and one to feed a kryptonian-- the dumplings are done. Lena throws the 2 bottles in the backpack of Alex’s supplies, and with two steaming bowls in hand, walks upstairs.
Lena quietly walks into the room, setting the bowls on their bedside table, catching a peak of Kara’s glistening skin and a forming opaque pool just above her belly button. As she turns to put the backpack on the floor, she feels Kara’s hand on the back of her thigh.
“How are you feeling?” Lena asks, putting a hand on Kara’s.
“Horny.” Kara moans.
“Can I feed you?” Lena asks, finally turning to grab the large bowl. Kara’s hand moves with Lena as she turns, her hand now on the front of Lena’s black slacks. Kara’s eyes finally peek open, as if she had just smelled the food near her. The blonde licks her lips, her eye moving from the bowl in Lena’s hand, over to the hand she had on her girlfriend's thigh, and back again. Lena’s girlfriend was truly gone, this woman was just Alpha instinct. But Lena needed to eat, so Kara had to as well. Lena took the first dumpling in her fingers and bit half of it, keeping what little eye contact Kara would give her. Kara’s eyes were more focused on her hand that was now wandering from the front of Lena’s thigh to in between them. Lena put the half eaten dumpling in front of the blonde’s face, hoping to break her concentration. Instead, the kryptonian nearly swallows the offered piece without breaking stride. Lena took this as a good sign, and repeated this process with a full dumpling. Again, Kara took it with no resistance yet no concentration broken. With every dumpling eaten, Kara’s hand lingered between Lena’s thighs longer and drifted higher until both bowls were empty, Lena was sufficiently full, and Kara’s thumb was rubbing Lena’s clit over her pants.
“Let me put the bowls away.” Lena says, doing her best to keep her voice even. The minutes of focus she needed to keep feeding them both was starting to wear thin, especially as Kara was getting noticeably hard again.
“Can I have your panties first?” This request seemed simple enough, and Lena had wanted to change out of her work clothes anyways. Lena easily unfasted the button on the front of her slacks and let the black fabric fall to the area rug under her. Before she could begin the next step in giving Kara what she had asked for, Kara moved with lightning speed onto her hand and knees, ass up and face against Lena’s covered pubes. Kara moaned as if she was being directly stimulated, her face pressing against Lena as though she could be any closer than she was right now.
“Fuck, you smell so good.” Kara moaned, her right hand going towards her cock for the um-teenth time today. “Let me taste you, Lena.” It wasn't much of a question, or begging. Lena knew it was a command but she was hellbent on getting the one task she needed to do, done. Lena reached down, and took Kara’s chin in her hand, guiding her face off of her body. The blonde’s attention was still glued to her girlfriends covered pussy as Lena spoke,
“I'm taking the bowls downstairs, then getting into pajamas. Wait here.” As Lena let go of the woman's face and turned around with the bowls she could swear she heard a slight growl come from the Alpha. It only took her a few seconds to come back to the room and see that Kara had picked up her slacks from the floor and her face was in the crotch of them. Lena pulled a small bottle of lube from the backpack near the doorway then walked up to Kara who was still on her hands and knees.
“Give me your hand.” Lena says, gently but sharp enough to make sure Kara can hear her over the blood rushing to her cock. Kara does as she is told as Lena squirts the lube into her hand. As soon as Kara’s hand goes back to where it was, she lets off a guttural moan before looking back at Lena.
“Let me taste you.” Kara says, more harshly than last time. The facade of asking, quickly dropping with every moment between them.
“I want to get comfortable first.” Lena says before taking her shirt off in one fluid motion. A motion that sends more of Lena’s scent directly into the Alpha’s bloodstream. This, with the sight of Lena’s barely contained breasts in her bra made Kara’s balls tighten and precum dribble from her tip.
“Lena.” She wasn't sure if her name was begging, a warning or a threat. The urge to tease the woman in front of her was strong but the mystery of what she would do if pushed to the edge was troubling enough that it led her to swiftly reach back and take her bra off. The straps were barely off of the back of her shoulders before Kara’s hand took over in ripping away the fabric and pushing it into the growing pile on the bed. The sudden motion pulled Lena forward, not enough that either of them would have noticed in any other situation. But tonight, Kara took advantage of the few gained inches by taking the now exposed pink nipple into her mouth. The new sensation forced a moan past Lena’s lips as she takes the half step forward to stay close enough for Kara to continue.
Normally, Kara would take her time with Lena’s nipple, knowing the buds would get sensitive quickly and the kryptonian's tongue could be too rough if she wasn't careful. Tonight, she wasn't being careful. Kara’s now lubed hand stayed at a constant pace over her shaft as she continued to draw moans from her girlfriend. It wasn't long before Lena’s arousal was overwhelming Kara’s Alpha senses and cum was dribbling from her cock again. When Kara puts her hand back on the bed, now on all fours, Lena takes this as her chance to take a step back. This pulls a growl from Kara.
“Rest, darling.” Lena puts a hand on Kara’s shoulder, feigning a push as though she had any hope in moving the other woman if she didn't want to be moved. Kara takes this moment to reach for Lena’s hips, spin her towards the bed and mount her. A quick and forceful motion that was more aggressive than Kara had ever been with Lena yet was still the gentle woman that would never dream of leaving a mark on Lena (at least an unintentional one). The Alpha’s semi hard member now lies between the two as she towers over Lena, faces less than an inch apart.
“Let me kiss you.” It was as though the part of Kara that always asked for consent was fighting a losing battle to this new state of mind. Lena, nearly overwhelmed with the smells surrounding her, gave a small nod before Kara’s lips were crashing into her. Kara’s hands grip the clothing and towels above Lena’s head roughly. Her arms nearly shake as she strains to keep her need under what little control she can maintain. When Lena’s hands fall to the Kryptonian’s upper thighs, it's all Kara can do to not reposition to be inside Lena immediately. Instead, Kara consumes Lena’s mouth. She pushes her tongue as far into the other woman's mouth as her tongue will allow, not letting Lena close her mouth until she makes herself pull away. As soon as the connection is lost, Lena takes a breath and can only take stock of two things: the smell of dirty laundry, and the pool of pre cum now on her stomach.
“Kara, we need to shower.” She thought she was willing to put up with a lot during her partner’s heat cycle, but this smell couldn't be one of them.
“I need your smell.” Kara growls into the bed next to Lena’s head, her hips beginning to move over her partner's bare stomach.
“You’ll have me all day, for as long as you need, but I cant fuck you in this mess.”
“Not a mess. It's my nest of you.” more precum dibbles over Lena’s stomach, coating Kara’s balls as well.
“You don't need a nest,” Lena says, putting a hand on Kara’s cheek, hoping to get her to focus a bit more. “Ill lay in bed with you as long as you need.” Kara lets out a small whimper, her hips moving faster as she feels another release coming on. “We’ll get in the shower, clean up the bed sheets then you can have as much of me as you need.”
“Fuck, Lena. You smell so good.” Kara moans as streams begin to shoot towards Lena’s breasts. After a few seconds, Kara sighs and rolls to her side. “Ok” She exhales, “Ok, ill shower” Lena takes this opportunity before Kara loses it again. She quickly stands and moves towards the supplies bag, taking out the black tube and more lube.
“Alex brought this for you. I'll start a bath.” Lena places the toy and bottle on the bed next to a heavily breathing Kara before walking through the bedroom into the en suite bathroom. She begins to fill the jacuzzi bath tub before walking back into the bedroom. Kara seems not to have moved from the last place Lena had left her. Eyes still closed, breathing hard.
“You need help to the bath?’’ Lena asks quietly. Kara lets out a shaky breath out her mouth before saying,
“Will you join me?” This voice is the most the Alpha had sounded like herself since her heat started. Maybe she could fight through this after the initial shock.
“Ill clean up the bedroom then be right in.” This had been her plan all along but she was happy to reassure her needy partner as much as she needed. Kara lets out another shaky breath before slowly sitting up, then nearly limping to the bathroom. Between her glistening, sweat soaked skin and rubbed raw, semi hard- on Lena didn't know what to be more worried about. As soon as Kara took her first step into the water, Lena began collecting all of the clothes, towels and sheets from the bed. She was intent on not letting Kara wait too long for her. It took her less than two minutes to throw new sheets onto the bed (she was sure they wouldn't need blankets), and light half a dozen candles all over the room. After throwing her underwear into the laundry and stripping completely naked she joined Kara in the bedroom where she again lay with her eyes closed and her chest heaving for air.

“How are you feeling?” Lena asks, walking into the bathroom, the toy she had brought from the bedroom hiding behind her back.
“Its so hard to control.” Kara’s hand twitches where they rest on the side of the tub as she continues, “I'm sorry about the nest, and throwing you-” she pauses before adding, “and cumming on you.” Lena lets out a small amused chuckle at this.
“Youre doing so well, Kara. It's my fault you're in this position. I want to help you through it.” A breath passes between them, Kara’s hands never stopping their constant fidgeting. Lena had never seen the woman so out of control of her own body before. Kara finally breaks the silence,
“The smell of your arousal makes me lose control. Without your scent, I lose my mind trying to look for you. I don’t know how to get away from this.”
“I don’t think you are. So we’ll manage it together.”
“My cock is throbbing, Lena.”
“Then I’ll manage that for you.” Lena takes this as her cue to fully enter the bathroom and sit on the edge of the tub. Here she can get a better look at Kara’s member standing at full attention, the tip glistening from water, pre cum, or most likely a mix of both. With the toy in her left hand, Lena puts her right in the soapy water before cupping some and bringing it to the center of Kara’s chest. The water is warm, but nowhere near warm enough to warrant the amount of sweat coming from Kara’s skin.
“Breath, Darling.” Kara obeys shakily, letting out a long and labored breath from her mouth. Before she can take the next breath in, Lena has the toy in her right hand and over the tip of Kara’s cock.
“Gods, Lena!” Kara all but yells as she fights to keep her eyes closed and her hands on the edge of the tub. Lena moves the toy only over the head of her Alpha’s cock as her left hand takes a squirt of shampoo and begins to rub it into Kara’s matted hair. It feels both like torture and heaven to the Alpha as she is bathed and stroked. Massaged and edged. So much touch and yet not enough all at the same time. Whimpers fight their way out of her throat as the soft squeeze of the flesh light draws her release closer again.
Lena does the best she can, working shampoo through blonde locks and getting as many tangles out as she can with one hand. Once she does all she can she leans close to Kara’s ear, hoping to get past her thoughts of breeding and saying,
“Rinse out your hair, Darling.” Kara slowly sinks into the water, keeping her hands on the edge of the tub and her cock in the sleeve in Lena’s hand. Lena is sure to follow the Alpha as she sinks then finds her place again. Once Lena checks that there's no longer soap in the woman’s hair, she allows Kara five full strokes before taking the toy off of her cock completely. Piercing blue eyes meet green ones for the first time in nearly 20 minutes. Lena knew the Kryptonian only felt love for her, always. Even in their most heated arguments, Kara had never had a thought of harming her girlfriend-- this is the closest she had ever been. Lena interrupts the look by first standing and then saying,
“I need a bath too, and the toy was in my way.” With this, Lena steps one long, tanned leg into the bath and then the other, standing over either side of Kara’s hips. The Alpha spent no energy in pretending she wasn't looking at the only thing that consumed her brain right now. Blue eyes stared at dark brown pubes as they lowered closer and closer to where Kara wanted to be most. Lena wasted no time in giving her Alpha exactly what she wanted. For as much pain as Kara looked to be in over the past few hours and all the sad noises she's made, the woman being hard for her all day was also a major turn on. Lena had been fighting her own horniness all day. If she felt like this any other day, she would have been begging Kara to fuck her, but someone had to focus tonight and it wouldnt be the Alpha in heat. Now, Lena could finally get what she had been teased with all night. Her wet pussy took in all of Kara’s length with ease as they moaned together at the way they perfectly fit together. But Lena had to keep her focus. She would have time to ride Kara all night, probably for days. Right now, she needed to be, at least partially, clean.
Once the initial tremors of arousal fall away, Kara rests her head on the edge of the tub again but this time with her eyes laser focused on the ceiling. Lena reaches behind the blond to grab the body soap, squirting pumps of white soap into her palm. The imagery while in this position is not lost on her but she quickly rubs her hands together to keep some facade of focus. She quickly moves her hands over her body, lathering her arms and chest and her stomach even though the water washes it away immediately. Then, she embraces Kara. Her hands wrap around the blonds neck and their chests press together. All of the new touch, their sensitive skin, and the change in angle make them moan together again. Now that Lena felt like the task she set out to complete was done as well as it could be, she begins to rock her hips as she leans down next to Kara’s ear and says the words she was sure would set a new fire in the Alpha’s blood,
“Cum inside me, my Alpha.” all the hesitation and restraint left the blond in this moment. The hands that she had kept fixed to the side of the tub were now gripping her mate’s hips harder than she ever had. The hips that had been cemented to the floor of the tub now drilled up. She thrust hard against her partner, barely hearing her screams and moans over the rush of blood flooding her cock. With all the teasing Lena had done it didn't take long before Kara felt her cum rushing towards her mates pussy. She counted her strokes in her head: ‘three, four, five’ she lifted Lena off of her and rubbed her girlfriends ass over her cock as she came into the bath water with a loud grunt. Kara hugged her girlfriend tight against her, all too aware of her clit and pussy throbbing against her stomach.
“You didn't cum inside.” Lena says, more of a question that her tone indicated.
“I can't." The Alpha pants, trying to collect the energy to get out of the tub.

Chapter Text

It only took a few seconds for Kara to gather her energy, wrap her arms around Lena and lift the both of them out of the tub. Neither of them registered all of the water they had thrown out of the tub during their… activities. Kara easily walks the two of them into the bedroom, water drops lining their path to the bed. Lena feels her back gently touch the new bedsheets as Kara sets her down before placing a gentle kiss on her forehead, then lips. Pale arms move from under the brunette as she moves her mouth to the center of Lena’s chest, then her stomach. Kara sits back on her heels as her hands sneak under Lena’s ass and her pink mouth meets the goal she's had in mind for hours. Lena’s hands meet the sides of Kara’s still damp head as gentle kisses and licks overwhelm her clit. But even with the distractions drawing her already sensitive clit to another orgasm, what Kara had said in the bathtub was stuck in her mind.
“Kara,” The name comes out a moan but Lena presses on, “What did you mean you can't cum in me?” The vibrations of a growl coming from Kara push a surprised moan out of the Luther's lips. Still her eyes stay trained on Kara, hoping to get half an answer from the busy woman. Kara dips her tongue into Lena before slowly lapping up to her clit again. The logical side of her wanted to answer the question in the air, but the taste of Lena’s pussy on her tongue was making logical thought nearly impossible. Before she lost herself in eating out her mate all night, Kara forced herself away long enough to answer.
“My knot will hurt you too bad.” She knew it was barely an answer but she couldn't wait any longer to taste Lena. Her tongue immediately entered Lena again, making the woman jerk underneath her in both surprise and pleasure.
“Fuck! Kara,” Lena screams before she can get back on topic, determined not to let her looming orgasm distract her from getting information, “What knot? You've cum in me before and it didn't hurt.” It didn't happen often, mostly from Kara’s fear of being too out of control when she finished, but the few times Lena had tied her up and been on top she had made Kara finish inside of her and there was no ‘knot’. Before she can think to ask the woman to explain more she feels the pressure of Kara sucking her clit and the familiar heat pooling in her stomach of another finish line incoming. Kara’s hard, dripping cock brushing against the bed sheets wouldn't break her focus on her girlfriend's clit, not until she got as many orgasms out of her as she saw fit. The first of what Lena feared would be an unending amount of orgasms rolled over her as she squeezed her thighs around the blonde face. The Alpha nearly came herself as her tongue eagerly lapped at the juices spilling from the needy pussy in front of her. The focus in her actions were intense and unending, Lena was unsure if her orgasm would end at this rate. It took until Lena was pushing Kara’s head away from her as she said ‘stop’ as seriously as she could muster before Kara moved her mouth from her sensitive clit, to the inside of her thigh. The sucking and biting still sent shivers through Lena but it at least gave her clit a break.
“Explain the knot.” Lena finally sighed out after almost fully catching her breath. She hadn't realized her eyes were closed until she had to open them to look at Kara to be sure she had heard her question. Bright blue eyes stare at Lena for what feels like forever, the sharp pinching of the blonde’s teeth would not distract her. The focus Kara had earlier to answer Lena’s questions was far gone and long forgotten. Her alpha needs taking the driver's seat to logic. In her final effort to assuage both, Kara quickly sits up, places herself between Lena’s thighs, and sinks her cock into Lena’s oversensitive pussy to the hilt. The scream that is forced out of Lena is loud enough for any neighbors to have heard if she had any nearby. She had never been so glad to have a house so far away from the city and a proper neighborhood. Kara’s hands roughly grip Lena’s thighs and Lena’s hands cover Kara’s. It’s not long before another orgasm tightens Lena’s pussy around Kara and sends Kara into her final few thrusts. Again she counts in her head ‘three, four, five’ and as she draws back before the sixth she pulls out of Lena and shoots her cum onto her girlfriend's stomach. Before she can collapse however, she takes Lena’s right hand in her left and guides it a few centimeters from the base of her semi- hard on. The swelling in Lena’s hand is noticeable to say the least. She looks up at the flushed blonde before asking,
“Does it hurt?”
“No, but it will hurt you.”
“This is the knot?” Kara just nods at this, placing both her hands on the bed, on either side of Lena’s head.
“Why-?” She doesn't know exactly what she's trying to ask but luckily Kara steps in to answer.
“To make sure you get pregnant. That my cum stays in your pussy.” Lena was sure she hadn't heard Kara say the word ‘pussy’ more than a couple times in their relationship. Hearing it from the woman now was jarring. She had almost forgotten how new this situation was. Lena nods at the answer, unsure how to keep Kara satisfied and herself in one piece. Kara slowly drops from her hands to her elbows above Lena.
“Time to sleep?” Lena asks, not realizing how long their day had been until this pause. Kara nods her head, eyes already shut as she lets her right shoulder fall to the bed. With Kara’s right leg and arm draped over Lena, the two fall asleep in record time.

Chapter Text

Lena woke up in a coughing fit. She hadn't realized how thirsty she was when she went to bed and was paying for the lack of water now. She slowly peels herself out from under her girlfriend, happy to know that even in heat, she's a heavy sleeper. It's not until now that she also realizes the bright room light is on, washing the room in blinding light for her sleepy eyes. Once Lena is able to sit up on the bed she turns on the bedside lamp, stands up and turns off the overhead light then heads downstairs. Once in the kitchen, she pours herself a glass of water, downs it in nearly one gulp, then refills it again. As she turns around to grab yogurt and granola she catches the time from the microwave:5:30 AM. Why was she awake and eating at 5:30 AM? She hadn't realized how little she had eaten the day before until she took her first bite of granola.
Once her bowl is empty and another glass of water is drunk and refilled, she takes it upstairs with her, hoping to get a few more hours of sleep before her girlfriend wakes up. Normally Kara was a late riser, so maybe this would also over-ride her being in heat. As Lena walks into the dimly lit bedroom she sets down her glass of water on the dresser, before turning towards the bed. Her girlfriend is still asleep, her mouth slightly open as she softly snores. The relaxation of her face is in direct contrast to her body though. Kara lies, slowly humping the bed, her cock leaving dribbles of pre cum where she lies face down. Lena lays on her side of the bed, facing away from Kara and closing her eyes in hopes to get a few more hours of sleep.

When she wakes again it's to the sounds of heavy breathing next to her. Before she can turn around, she hears the wooden head board let out a whine. Lena rolls over to see Kara with her eyes closed, face up, arms above her head holding the head board. The alpha's body glistens with sweat where she lays squirming.
“Kara?” Lena whispers, hoping not to startle the woman.
“I'm awake.” the blonde says through gritted teeth. Lena swiftly moves out of bed, collects the toy from the bathroom and the lube that had been thrown on the floor then sits on her knees next to Kara on the bed.
“I didn't want to wake you up.” Kara says as soon as she feels the dip on the bed when Lena sits. It always amazed Lena how even when Kara was in the worst position possible, in the most amount of pain, she would always think of keeping her safe and comfortable first. Lena took in the words as she poured lube into the toy.
“May I take care of you?” Lena asked, not wanting to surprise Kara or tempt her if she was trying to push through this. The constant erection seemed so uncomfortable, she wanted to give the woman any break, if possible.
“You don't have to.”
“That's not what I asked.” The head board lets out another creek. Lena keeps her eyes on Kara waiting for the go ahead while also making a mental note to fix the head board once all of this is over. Kara nods her head, finally giving in to the pressure in her balls. Lena wastes no time in covering the glistening member in front of her with the silicone toy. Kara’s sigh of relief and pleasure is music to Lena’s ears. She was happy she could provide her any kind of relief. Lena slowly strokes the entire length of the alpha, pausing at the tip, before repeating the process.
“It feels so good, Lena.” Kara sighs, pushing her hips further into the toy to meet Lena at her base. Lena hums in response, keeping focus on her rhythm. “The toy feels so good but you feel so much better.” This takes more effort for Lena to ignore, but she keeps herself focused on the toy. “I want to feel you wrapped around my cock all day, every day.” Lena’s hand moves faster at the words coming from Kara as the woman strains against her hold of the head board. “I want to cum in your pussy over and over until I finally get you pregnant.” Every word comes out closer to a growl than the last as her hips beat Lena’s pace to drive further into the toy. “And I know you want it to because I can smell you getting wet for me.”
“Shut up, Kara.” Both of their focus was crumbling fast and Lena needed this to be over before she broke first. Watching her girlfriends hips buck desperately combined with the words hanging in the air were getting to her fast. She had to remain in control enough for the both of them.
“Fuck me, Lena. Fill your pussy with my cum.” It was a taunt. Kara had never taunted Lena while they had sex. This alpha was trying to prove a point though. Lena stroked faster instead, meeting the pace Kara was trying to set with her hips. It only took a few strokes for the head board to creak again and the toy to be filled with cum… and the black plastic surrounding the silicone, to crack. Lena’s eyes shot up at this. She had forgotten about the knot just that fast, and if she had needed a reminder on why having it inside of her was a bad idea she now had the cracked toy in her hand.
“You smell so good.” Kara growls out, clearly un disturbed by the broken toy around her semi- hard on. “Let me taste you.” Lena has to laugh at the one track mind of the woman laying under her. She finally moves the toy, throwing it near the supplies backpack before responding in a laugh,
“You just broke the toy, you know?”
“Let me taste you.” The words repeated both turn Lena on and make her laugh.
“You really have a one track mind.”
“Come sit on my face before I make you.” This knocks the breath out of Lena’s lungs.
“Kara, I-” Before she can say another word, the kryptonian uses her super speed to get to her knees, grab Lena’s ass and pick her up to sit on her strong slim shoulders. Lena reacts as quickly as she can, grabbing the back of Kara’s head as her clit is roughly sucked and licked without warning.
“Kara!” The name is yelled both in shock and pleasure. She knew she was safe in Kara's arms, always, but that didn't change the fact that she doesn't like being in the air if she could help it. “Put me down, Kara.” The unconvincing moan doesn't make it to Kara’s ears. Between the blood rushing back into her member and Lena’s thighs covering her ears, nothing would stop her from using Lena’s ass to push the woman's pussy as close to her mouth as she could get it. But there was still a part of the blonde’s brain that remembered who was in her arms. This wasn't just any mate who would roll over for an alpha. Lena wouldn't be able to relax while in the air, but Kara’s foggy brain couldn't risk her mate being away from her for even a second right now. Kara moves as slowly as she can manage to turn them around and walk to the wall on her knees, her tongue never skipping a beat in moving against the sensitive nub in front of her as she settles Lena’s back against the wall.
“Thank you.” Lena sighs, as she rests her back against the cool surface as she scratches the top of Kara’s head. Kara lets out a gentle moan in acknowledgement, sending vibrations though Lena. Now, with the security of having something to press her back against, the brunette rolls her hips against Kara’s face. The movement makes Kara’s head spin and she grips Lena’s thighs harder to keep some semblance of control. This would definitely leave a mark on her pale thighs.
“Kara, I'm gonna cum.” Lena warns to deaf ears as her hands hold Kara’s tightly. She can't think to warn her again before she feels her body begin to tense and toes curl. But Kara doesn't slow down. “Kara, stop!” Lena whines, now using the same hands she had been using to keep her close, to try and push the woman away. “Ok, Kara. I'm done.” She squirms between the wall and the relentless alpha, her thighs now away from Kara’s ears, she tries again. “Kara, I need a break.” As Lena’s hands move to the other woman's forehead, she hears her phone chime on the bedside table. “Kara, I need to check that. Let me down.” Without earmuffs, Kara hears her mate’s pleas and growls in response. “OK.” Lena finally submits, losing her breath as her clit goes numb. Her body goes slack between the wall and her unyielding partner, her hands resting on the alpha’s forehead. After a few seconds of Lena trying to catch her breath, she was about to try to talk to Kara again before the Alpha readjusts: moving so that her forearm becomes a bench for Lena and her other squeezes between Lena’s pussy and her own mouth.
“Kara, I cant-” She's cut off by the gentle finger’s entering her, pushing a moan from between her lips suddenly. For as sensitive as her clit was, the massage to her G- spot was a welcome distraction. She hadn't noticed how close Kara had pushed her to another orgasm until her thighs started to tighten again. She didn't have time to warn the woman before she was pushing her hips into an eager mouth again as she was cumming. Kara growls again as she feels Lena tighten around her fingers, feeling the sudden need to replace it with her painfully needy cock. Before Lena can try to protest again, her back is being rested against the bed and Kara is already lining herself up. There’s a breath between them. Their lock eyes for only a moment. Lena’s reassurance that no matter how needy Kara is, she's still the woman she knows.
They take a breath together, Kara accepting Lena’s silent consent before connecting their hips. Kara sits up straight, holding Lena’s thighs tightly as she feels her balls tighten, realizing now how close she had gotten just while eating Lena out.
“Kara, I'm gonna cum again.” Lena warns, gripping the sheets under her in fits. “That angle is so good, I-”
“Shut up before I cum inside of you!” Kara nearly yells before she pulls out and cums on Lena’s stomach. She doesn't take a break though, quickly replacing her cock with her fingers again until Lena comes around her. Before the brunette can fully catch her breath, her phone chimes again.
“Who is that?” Kara asks as Lena reaches for her phone to check the most recent messages.
“Alex dropping off food.”

Chapter Text

Lena climbs out of bed on wobbly legs, opening her drawers to find a loose fitting T-shirt and silk pajama bottoms. She knows no neighbors are close enough to see and she would only be on her front step for a second but she doesn't want to take any unnecessary risks. Kara lies on the bed, watching Lena’s every move, every sway of her hips as she rebalances herself while dressing.
“Ill be right back.” Lena says over her shoulder. She takes her glass of water with her, finishing it before she makes her way to the kitchen. It only takes a second for her to open her front door, take the two grocery bags inside and lock the door again. Lena opens one to find a warm bowl of ramen and the other with ice packs and more lube. The latter made sense but the reason for the former didn't click until she dropped her hand on her thigh absent mindedly and was met with the pain of a forming bruise. The ice packs are mediately placed in the freezer.
“Kara, I'm having lunch if you want anything.” Lena says as if the woman was standing right across from her. Without waiting, she opens the soup and begins to eat. Any other day she would wait for Kara to join her first, but she was starving, and with no concept of when Kara would give her another break, she wanted to take the time to eat what she could now. After another second, Kara makes her way down the stairs, completely naked. Her usually pale skin looks ghostly after hours away from any sunlight. The only color on her skin being blotchy red marks on her cheeks and chest. As she walks closer to the freezer, Lena can't help but notice the knot still present near the base of her semi- hard on. She watches Kara grab a bag of dumplings from the freezer before sitting across the kitchen island.
“Why won't it go down?” Lena asks after slurping another fork-full of noodles. She is close enough to being finished that if anything starts during this conversation, she would have had enough to eat for a few more hours. Kara rips open the bag before grabbing two at a time, using heat vision to thaw them, then eats them quickly.
“Because I’m not finishing inside.” She takes another two and repeats the process. As Lena finishes the last bite of ramen, she reaches into the refrigerator for a protein shake. She had to remember to thank Alex again for looking out for her.
“If you're… instincts” it seemed like as good of a word as any, “felt you finishing inside me, you would get soft?”
“For a bit, yeah. I would still need to go again but it wouldn't be as fast.” Lena nods at this, watching Kara eat a few more handfuls of dumpling before realizing,
“Wait, how are you so sure? Surely they didn't teach you this on krypton.” Kara nods at this, answering around her food,
“They had taught me some of this back home, but a lot came from research me and J’onn did when I first joined the DEO. It felt necessary for us to know everything about how the heat cycle could affect my performance as Supergirl.” Lena nods at this knowing the need for information her girlfriend, J’onn and Alex all shared. By the time Lena finished off her protein shake, Kara had emptied her bag of dumplings and was making her way to the other side of the island, where Lena watched her carefully. Kara stops herself, making eye contact with the woman and using the rest of the logic she has left for the moment to ask,
“Is it too much?” This question had turned Lena on more than anything that had happened all day. Kara using what little brain power she had to ask for clear consent is what made Lena fall in love with the woman. Kara could smell what the question did to the woman in front of her and fought the urge to close the distance between them before getting a clear answer.
“I can tell you're doing your best to be gentle.” Lena says, reaching for the hand Kara had placed on the counter between them.
“You make it so hard to stop.” Lena watches the alpha’s member twitch between them, acting almost as a count down timer for Kara having any reasonable thought. “May I kiss you?”
“Gentle.” Lena responds, watching Kara slowly take the step to stand between her legs and place gentle kisses on her swollen lips.

Chapter Text

Gentle kisses don't last long. Lena’s resolve had crumbled despite her best efforts. Between the moan she had let slip and her arousal clouding Kara’s senses, it doesn't take long for Kara to pull Lena’s clothed pussy towards her hard member.
“Not in the kitchen.” Lena nearly moans as she drapes her arms over Kara’s shoulders. The blonde doesn’t hesitate in taking the hint, picking the woman up by her ass and walking them back to the bedroom.
The next events happen faster than Lena can process them happening. In what feels like one fluid motion, Kara sets her on the edge of bed, drops to her knees, rips open the crotch of her pants, then attaches her mouth to the still over-sensitive bundle of nerves that is now exposed.
“Kara!” Lena yells at her in shock and pleasure.
“Ill buy you new ones.” Kara growls as she drives her tongue deep into her girlfriend, drawing out as much of her arousal as she can reach. Lena’s hand reaches between them, covering her clit from the rest of Kara’s mouth.
“Not my clit, please.” Kara doesn't protest this, still getting to have her fill of Lena. She is willing to compromise for now. With the growing pain of her cock, she wouldn't be able to eat Lena out for too much longer. Once she feels like she's had as much of Lena’s scent as she could take she quickly replaces her tongue with her member, drawing a scream from Lena in surprise.
“Kara, please don't stop.” Lena feels that familiar warmth start to pool in her stomach fast. As she feels another orgasm roll over her Kara lets out a deep breath in concentration. She doesn't want to cum yet, she has to let Lena finish before she allows herself the same, but the grip around her cock, the way Leana talks and the heady scent of her mate’s arousal is the hardest uphill battle she has ever faced. Kara waits as long as she can, letting her girlfriend ride out her orgasm for as long as possible before she draws back and cums between them on Lena’s shirt. Lena barely has a chance to adjust to being empty before Kara falls to her knees again, her tongue entering Lena but doing her best to avoid the woman's clit like she had asked for. Lena’s hands found their spot on either side of the blonde’s head again, trying not to roll her hips into the alpha's waiting mouth too much but finding the task near impossible. She was beginning to wonder if the cloudy feeling in her head now was anywhere near what Kara had been experiencing for nearly 48 hours.
Lena felt her body fall into the relentless rhythm of Kara’s mouth. She would lick out to her entrance- Lena's hips would tilt down to accommodate. When her tongue dipped back deep inside her- Lena would push her ass towards the woman's waiting mouth. Lena can almost fall asleep to the rhythm, her body making peace with the un-ending orgasm. Just as she is beginning to feel herself fall asleep in orgasmic bliss, Kara stands up, thrust into her until Lena tightens around her cock then drops to her knees. But she doesn't begin eating Lena out right away. Instead she turns to grab a bottle of lube that has been thrown on the floor, pours some into her hand then jerks off until she cums on the floor, growling into Lena’s pussy as she begins licking her juices again.
It had been hours of this pattern: Lena finding the rhythm of Kara’s tongue, nearly falling asleep until Kara made her cum on her cock. The pool of cum grew on the floor for hours until Kara came on Lena’s shirt one last time. Finally she had the presents of mind to help the woman undress, moved them to the center of the bed, and they both passed out wrapped in each other's arms.

Chapter Text

Lena is the first to wake up again. She quickly goes to the bathroom before making her way downstairs. She notices not only the bruises from before starting to get more sensitive but also the soreness of hours of sex catching up to her. As her coffee begins to brew she breaks open the vitamins Alex had given her and swallows them with a protein drink. She owed Alex a lot of favors when this was over. Once the young Luther has made and eaten a breakfast of eggs and fruit and finished her coffee she heads back upstairs. She finds Kara in the same position as the morning before: half on her side, humping the sheets. Lena was glad to see the last few days had taken as much out of the alpha as it had her. Lena takes this moment to check her phone, first scrolling through all the emails she had gotten the last few days. She knew she had hired capable people that wouldn't let her company burn down after a few days of absence. There were also emails from her team at the DEO, mostly updates and newsletter about Supergirl, or the lack thereof. Then she switched over to her messages with Alex. The 2 from yesterday read ‘Food has been delivered.’ and ‘Hope you're surviving, Luther.’ She never expected anything particularly heartfelt from the elder Danverse, her delivering food and supplies had been more than Lena had expected. Messages like these were what she expected.
Lena puts her phone down soon after reading Alex’s messages and lays back down, letting her girlfriend be the big spoon, as usual. She had just begun falling asleep again when she felt Kara moving behind her. She was used to a semi- hard on against her butt in the morning-- morning wood still applied to Kryptonians. But the full erection moving against her butt cheek was something she hadn't experienced. The whimpering Kara did in her sleep while she moved to get some relief sent shivers down Lena’s spine. Maybe she should wake the alpha up, surely she would feel bad if she knew what she was doing. Before Lena could make her next move she could feel Kara stiffen behind her then let out a sleepy mumble,
“I'm sorry.”
“Are you awake?” Lena whispers, not wanting to wake up the other woman if she wasn't already. She waits until she is certain that no reply will come, then falls asleep again to the quiet snoring of her partner, and the feeling of the pulsing knot against her butt.
It’s not until a few hours later that Lena is woken up again to Kara’s gentle kisses on her shoulder and back. The two moan together in a sleepy haze. Kara holds Lena tighter against her chest, feeling the woman's heart quicken and the scent of her arousal filling the air.
“We should shower today.” Lena says, wanting to communicate to Kara before the woman’s hormones took over again. Kara hums at this, acknowledging her girlfriend without removing her lips from the woman’s skin. Lena lets out a soft breath as Kara’s lips connect to her pulse point. She does her best to keep her hips still but by the way she feels Kara hardening against her, she can tell the effort doesn't deter the woman. The harder Kara bites into Lena’s neck the harder it is to keep her cries of pleasure at bay.
“Let me fuck you.” Kara’s whisper comes out a growl before her teeth sink into Lena’s neck again, her hands roughly grasping at Lena’s chest. The mix of sensations make keeping her moans at bay impossible. Without a second thought, Lena cries out,
“Please.” It only takes a second for Kara to reach between their bodies, line up with Lena’s pussy, and sink deep into her as slowly as she can force herself to. The two moan together, the mix of Kara on her neck, nipples and now inside of her could send her over the edge at any moment. “Thank you for being gentle, My Alpha.” Lena praises the woman, knowing how hard it must be for the blonde to move slowly enough for Lena to feel herself be filled up inch by inch. The praise makes Kara bite harder into Lena, the mix of pleasure and pain making Lena clench around the member inside of her. Kara’s pace quickens at the feeling, not being able to keep her orgasm away any longer. She begins counting the last few thrusts in her head, ‘three, four,’
“Don't stop, I'm gonna-” Before Lena can finish, Kara pulls out and cums on her ass. Before the last rope of cum is finished shooting from her cock, she flips Lena onto her stomach, moves to the end of the bed and laps at the woman's entrance with an eager tongue.
“Fuck! Kara!” Lena yells in surprise and pleasure as she feels Kara’s quickly moving tongue driving her to her orgasm without missing a beat. Kara takes her time in drinking all the juices of the woman's orgasm before she sits back on her heels, letting Lena flip over to look at her. Blue eyes get wider as they fall to the tanned skin of Lena’s neck. The two had agreed not to leave any marks on each other-- though this was mostly a rule for Kara to follow-- and the scene on Lena’s neck was breaking the rules on a thousand different levels. The scene on her neck also made her alpha instincts go to a level she hadn't felt before. The overwhelming sense of ‘mine’.
“Kara?” Lena sees the shift in her girlfriend's body language before the blonde begins to slowly lean forwards and crawls between tanned legs. As soon as Kara is close enough, she leans into Lena’s unmarked side and makes it match the other. Lena’s confusion is quickly replaced with pleasure as Kara’s kisses and bites send her towards a new climax. Lena sinks her hands into blonde locks, making Kara growl and bite harder.
“I need to cum inside of my mate.” Kara rumbles, still hidden in Lena’s neck.
“Kara, I can't take your knot.” Lena whispers back, feeling the tip of Kara’s cock lining up with her entrance gently.
“It will fit.” She pushes in as slow as she can, feeling Lena take in her length easily. Lena gasps at the fullness as Kara moves an inch to begin marking her skin again.
“Kara, it won't fit.” The words come out as a moan as she pulls the woman’s face closer to her neck, the mixture of pleasure and pain sending her closer to her orgasm.
“I need to cum in you. You want me to cum in you.” Kara’s thrusts are relentless, the exact pace she knows will drive Lena over the edge. It only takes a few thrusts before the alpha feels Lena’s grip around her member tighten as she moans through her orgasm. Kara feels her release coming close, the last bit of logic in her brain far from in the room with her.
“You feel so good around me.” Kara growls, sitting up to admire her work as her hands move to play with Lena’s peaked nipples.
“Fuck, Kara.” Lena moans, riding her orgasm as the woman on top of her continues to thrust, “you can't finish inside.”
“I have to finish in my mate.” Kara repeats, feeling the tightening in her balls that tells her there's no turning back. She lets out a final growl as she sinks deep into Lena, letting her cum spill into her mate, finally satisfying her alpha needs.
“Fuck, Kara!” Lena yells, the pain finally over taking her as she sinks her nails into the woman's arms. “It's so full.” It was like nothing she had ever experienced before. It was thicker than any penis or dildo she had ever had inside of her. It didn't hurt as much as she expected it to but it wasn't comfortable by any means.
“Fuck, Lena. I'm sorry.” Kara pants in apology, looking down at her member still inside of her partner. She pushes the hair and sweat off of her face as Lena says,
“Pull out, it's too much.”
“I can't." Kara says sheepishly, keeping her eyes down in shame.
“What do you mean?”
“Your muscles are keeping the knot in. If I pull out it will probably break your pelvis at worst, and pop a muscle at best. The best option is for us to wait for it to go down.” Lena nods at the information, trying to move her hips to get some kind of comfort but finding none. A moment of silence passes between the two before Kara brakes it,
“We can shower together now.”

Chapter Text

Kara leans down close enough to her girlfriend for her to wrap her arms around the blonde's neck. The blonde picks up the woman easily, supporting her back with one arm as she walks them to the bathroom and turns on the shower.
“How are you?” Kara asks, waiting for the shower to get to Lena’s desired temperature. Lena rests her head on Kara’s shoulder, feeling the warm water hit her back as Kara steps them into the spray.
“Ok. I think you're starting to get smaller.” Lena leans back, both to make eye contact with the blonde and to get water on both of their chests. “How are you?”
“I’m so sorry I lost control. The marks on your neck made me think you were just any omega.” Lena reaches behind Kara to grab their soap, lathering it between her hands. She moves on from the question Kara ignored as she asks,
“Omegas have marks?” Lena moves the soap over Kara’s body, before her own.
“Alpha’s give their mates marks that keep other alphas away from them. I guess it just made me think you could handle-” she looks down at their connected hips, “this.” Once Lena puts the soap away, Kara steps them back into the water, washing the suds down the drain. The two stand in the shower for a few more moments, exchanging gentle kisses before Kara walks them out and finds a towel to drape over Lena.
“You sound like yourself again.” Lena comments, drying the both of them off as they walk through the bedroom, downstairs and into the kitchen.
“All of my blood isn't in my penis for the first time in days.” Kara chuckles a bit, handing Lena a glass of water. Once Lena is finished, Kara makes a bag of dumplings for the both of them to share. As they sit on the chair near the kitchen island Lena feels her thighs start to get wet. She looks down between bites to see white liquid spilling between the two and onto the chair. Kara follows her eyes before quietly remarking,
“So much for that shower.”
“Did you just cum again?” Lena asks, meeting the blue eyes in front of her. Kara swallows the bite in her mouth before saying,
“That's the cum the knot was keeping in you.” She then puts a dumpling in front of Lena’s mouth that the woman hesitantly takes.
“So the knot is gone?” Lena asks around the food in her mouth.”
“I would think so.” Kara says, eating the last of the dumplings. Lena nods at this, trying not to look too disappointed in this knowledge. Trying not to miss the feel of the fullness inside. Lena pushes off of Kara’s lap, going into the fridge to drink another protein shake as Kara quickly washes the dishes that have piled up over the last few days. It doesn't take long before both of them are done with their task and decide to take advantage of Kara’s moments of clarity to lay on the couch and watch a movie together.
