End Simulation - Chapter 9

There wasn’t much that surprised Lena once she discovered she was pregnant, and yet the sight of the flowing summer maternity dress that Kara chose to bring her certainly came close. She held the pretty fabric up to inspect it with a critical eye and estimated that it would rest several inches above her knees once it was on. Lena squinted at Kara thoughtfully, and wondered if anyone else would see it for what it was – easy access.
 

“I thought it would be quick to put on,” Kara uttered after a prolonged silence, her demeanor shockingly confident for an alpha who was standing with an obvious erection.
 

And quick to get under, Lena considered, with a haughty raised eyebrow that said she could read the Kryptonian’s mind.

Kara’s rut pheromones were mouthwatering and wonderful and it took all of Lena’s willpower not to suggest they throw everyone out and fuck all over the apartment until the whole place smelled of them.

 

“I don’t suppose you’d like to use that super speed of yours to clean the bathroom of our mess while I slip into this?”
 

If Lena laid on a little charm it wasn’t entirely her fault. Kara was affecting her more than the last time she had been in rut, and that was purely because the alpha had claimed her. She rubbed her thighs together to take the edge off the insistent throb of her clit and smirked when Kara whirled around the bathroom in a blur.

Everything was sparkling in the blink of an eye and Lena gaped at Kara when she stepped forward with a quiet rumble, “Your turn.”

 

It took her a moment to realize Kara was waiting for her to strip off and the air around them felt charged with heat when she flung off her shirt and stepped out of her messy leggings and panties that were still around her ankles. She was about to pull her bra back on when Kara stopped her with a whispery command. “Leave it off.”

 

It was a terrible idea, and yet her nipples felt sensitive under Kara’s heavy gaze, so she slipped on the delicate dress and held her hand out expectantly for panties to accompany it. The sexy little thong that Kara offered her wasn’t quite what she had in mind, yet it was empowering to see the way the alpha stared at her.

 

The dress was low cut and her breasts looked huge in the thin embrace of the cups, but Lena felt no shame when she glanced at herself in the mirror and washed off her lipstick to re-apply a fresh coat.
 

“Well I look presentable, but you certainly don’t.” She gestured to the prominent tent that was straining towards her and smirked when Kara glanced down at it with a huff. “I don’t know how you’re going to conceal that, but you can’t leave the bathroom until you do.”

 

Kara opened her mouth with the faintest hint of a grin, and Lena stopped her dead in her tracks with a raised finger. “Before you suavely suggest I help you, I have to get out there before the entire party comes back to check on me.”

The alpha pheromones in the air expressed disappointment and Lena reached out to grasp Kara’s shirt to pull her forward for a kiss. 

“After everyone is gone, I’ll more than make it up to you,” Lena promised with a flirtatious arch of her eyebrow and a gentle last touch to Kara’s arm. She hurried out of the bathroom after that, if only because the scents were overpowering and she would have stayed otherwise. 

She tried to make her face neutral as she strode back into the living room. Their friends and family appeared to be gathered around with drinks and they all turned to her when she stepped into view. 

“We were just about to form a search party,” Alex quipped affectionately, and Kelly slapped her on the arm and then leaned into her with a smile.

 

“Don’t mind her. She’s just excited and desperate to feel her future niece or nephew kick.” Kelly supplied with a chuckle. All the attention shifted to Alex and Lena let out a soft exhale of relief when Kelly winked at her.

 

Lena mouthed a silent thank you and glanced over her shoulder for any sign of Kara.

“Well, get over here mama, this party is for you.” Sam encouraged her with a wave of her hand, and Lena rolled her eyes, but discovered she was unable to stop her smile from forming.

 

Was this what normal felt like? The gentle hum of happiness in the background without any sick lurch in her stomach or foreboding to accompany it? It was foreign and uncomfortable to her, and Lena couldn’t explain why that made her feel vulnerable, but it did.

 

“Oh hey, are you okay?” Sam asked in a whisper and rushed to her side to wrap her in a warm hug. “What’s wrong?”

“Nothing,” Lena admitted with a soft, self-deprecating laugh. “And I guess I’m not used to that.”

“Or this, huh?” Sam settled her hand on the swell of her belly and gazed at her with kind, knowing eyes. “Look, motherhood is wild, I’m not gonna lie, but the best advice I can give you is to embrace the changes. In your life, in your body, in your moods, because everything is going to be okay. We’re all here for you.” Sam promised with a soft squeeze to Lena’s arms.

Emotion left Lena’s tongue stuck to the roof of her mouth and she struggled to respond as she rubbed her hand over the swell of her stomach and considered how different her life had become in just a matter of months. Most people got nine of those to prepare for bringing a new life into the world, and she had barely gotten three. What if she wasn’t ready? What if the baby burst out of her in a blaze of laser vision and decapitated the doctor and nurses?

The sudden horror gripped her so intensely she almost missed Kara’s return. 

Kara was wearing a pair of Lena’s tight jeans and a big, soft woolen sweater that was obviously intended to conceal her cock.


“Isn’t it bad enough that you’ve taken my daughter, you have to take her wardrobe too?” Lillian uttered as she waved her hand at Kara’s new attire. “I hope you showered first. That’s virgin wool. I know, because I bought it.”

“Like I couldn’t just pay to replace it with all of my billions,” Lena intoned with a meaningful arch of both eyebrows as she pushed by her mother to get to Kara. “It looks good on you.” She placed a hand on the sweater and then subtly lowered it, so her fingertips brushed against Kara’s hard cock. 

 
“Please, anything would look better than her wardrobe from Old Navy or the discount rack at Nordstrom,” Lillian sniffed and popped the olive from her martini into her mouth. “Not to mention the ridiculous spandex you — you wear to the gym.” She finished softly as she glanced at their guests who were unaware of Kara’s superhero identity. 

 
Lena shot her a glare of warning as her mother almost let their secret slip. 

Lillian’s comments also had the added effect of bringing back all of Lena’s anxieties related to birthing a super baby. 

She cupped her belly as she felt a small foot jab at her and a high kick landed just behind her ribs.
 

“It seems the baby responds to the sound of its grandmother’s voice with rage,” Lena remarked with a smirk and placed a hand on Kara’s shoulder. 

 
“Nonsense, it’s excitement,” Lillian insisted, and despite her frosty attitude towards Kara, she rushed over at the same speed as Alex to feel the baby kick.


Lena tried not to grimace when she had two sets of hands rubbing over her swollen belly, cooing at it like a couple of witches gazing into a crystal ball. 

“You know, it’s customary to ask before you put your hands on someone.” She remarked candidly, and Alex had the good grace to seem embarrassed as she took her hands back.

 
“It’s also customary to at least date before you get pregnant, but you’ve always been the type to challenge the rules.” Lillian shot back, looking somewhat appalled by her own eager behavior to feel her grandchild moving around.
 

“And who raised me to be like that, I wonder?” Lena retorted smugly. It wasn’t often she got to see her mother rattled, and even rarer by her own actions.


Lillian tried to look composed as she straightened up, as if nobody had heard the way she had whispered to Lena’s stomach with excitement. Lena realized all at once that the entire baby shower might actually be worth it for that fleeting moment.

Kara was grinning from ear to ear, because whether Lillian liked her or not, the ice queen had apparently melted for their unborn child and Lena knew Kara would never let Lillian forget it.

 

 “May I?” Eliza asked, and Lena resigned herself for a moment to be passed around the party like some sort of favor to the guests.

 

 Kara never strayed from her side, hovering while emitting proud pheromones, as if nobody could tell how pleased she was from the way she kept eyeing Lena’s round belly.

 

“I’m only enduring your posturing because it hides the fact you’re in rut.” Lena whispered when the last person had gotten a turn at rubbing her stomach. “I’ve never allowed so many people to touch me in my whole life as I have the past five minutes, and if you think I’m going to let you put another baby inside me after that—”

“You will,” Kara husked, so confidently and calmly that Lena hated the way her cunt clenched in silent response to side with the alpha.

“I wouldn’t be so sure.” Lena lilted, her narrowed eyes taking in the cocky, almost arrogant lift to Kara’s chin that absolutely shouldn’t have been driving her wild. “You should douse yourself with something before everyone smells you, and also bring me a cupcake and a glass of milk while you’re at it.”

Kara dashed off with just a touch of speed to remain inconspicuous in the crowd of mixed friends. She came back smelling of the strongest scent suppressant Lena owned and presented her with a pink frosted cupcake and a brimming glass of milk. 

 
“I did your bidding,” Kara announced and stood poised with her hand on her hip, at the ready to do more if Lena so much as asked. “One cupcake and a glass of milk.” 

“Something tells me you’re highly motivated to please me today,” Lena teased and nibbled her lower lip in consideration of what else she might request. She took a few sips of her milk and devoured her cupcake, all prepared to get into the party spirit.

“Is it working so far?” Kara questioned with an adorable grin and head tilt, laying it on thick with the charm. “Can I interest you in a foot rub? Should I run out and get a dozen of those donuts you like? Maybe we could cuddle later and put on one of your favorite movies—”

 
“Oh, you really want to get laid, don’t you?” Lena asked with a faint smile curving her lips. She would have given Kara even more incentive to continue being so accommodating if it wasn’t for Sam calling everyone over to open presents.


“Lena, there’s a chair for you here,” Sam pointed out and beckoned her over towards the veritable mountain of gifts. 

 
“Oh, wonderful, right in the middle of the room.” Lena laughed, her wide eyes landing on Kara to signal that she required back up. 

 
While the party and intent behind it was clearly to show support for the new life growing exponentially inside her, Lena couldn’t help but feel like a spectacle as everyone gathered around in expectation to see how grateful and excited she was to receive the presents they bought.
 

Kara was thoughtful enough to bring her the gifts and then set them aside after.
 

Lena exuded as much happiness as she could while gradually being drained by the pressure to keep smiling for over an hour while she unwrapped box after box of the same, yet slightly different items.
 

Apparently you could never have too many onesies, changing bags, or breast pumps.

 

 “They know I only have two tits, right?” Lena whispered as Kara took the third pump away, and smirked when the alpha’s face brightened as she tried not to laugh out loud.
 

Lena had blenders, a stroller, bottles, teething rings and enough muslin cloths to feasibly form an escape rope if she tied them together. Abseiling off her balcony wasn’t the worst idea she ever had, but she restrained the impulse and tried to stifle a yawn when Kara carefully set aside the last item.
 

“Who is ready for a few games?” Lillian asked with a manic gleam in her eye. She was focused on Kara, who appeared to be concerned about Lillian’s enthusiasm.
 

Lena used her exhaustion for good when she sagged into the chair and rubbed her stomach. “As much as I’d love to participate in the fun, I think I need a little nap, but please, continue without me and I’ll see you all in about an hour.”
 

Soft noises of understanding rippled through the crowd of their friends and Lena grabbed Kara by the arm to lean heavily into her, which was a touch dramatic but served a purpose. It meant she could rub the alpha’s crotch without anyone being the wiser, and if Kara moved a little stiffly it was because she was supporting Lena’s weight, and not sporting an erection so big it made it difficult to walk.


“Lena,” Kara half whispered, half groaned as she steered them down the hallway and to the bedroom. “If you don’t stop—”

“I have no intention of stopping, just like I have no intention of sleeping.” Lena murmured and glanced up at Kara through heavy lashes. “Though I am cashing in on that foot rub you offered.”

She sat on the end of the bed to remove her shoes and then flopped back against the pillows to wiggle her toes at Kara. 

The alpha shut the bedroom door behind her and bounced over to tend to Lena with a big grin on her face. 

Strong aromas of exhilaration and sex surrounded Kara, and Lena contributed to the scents by taking her panties off. 

“Some ground rules: you can’t knot in me,” Lena warned as she caught notice of the frenetic, lustful gleam in Kara’s eyes. 

It would be terrible if any of their guests came searching for them only to find Lena very much awake with a knot inside of her. Even though her pregnancy hormones wanted it and her cunt was already gripping inside, she needed to be level-headed enough to avoid public embarrassment.
 

Kara perched on the bed and in that position, the sweater and jeans she wore couldn’t conceal her giant erection. She fidgeted as though uncomfortable and then began to knead Lena’s feet.

“I have plenty of self-control,” Kara insisted and pressed her thumbs over Lena’s sore soles, finding all of the places where she ached.
 

“I’ve experienced you in rut and you absolutely do not.” Lena reminded the alpha with a touch of amusement in her tone. They weren’t in a good place back then. She had been so bitter and hasty to inform Kara that they were bad for each other. Therapy took time and a lot of hard work, but it was worth it when it meant she could mention their past without souring from it. 

Lena knew they had a long road to walk until they were fully healed, the both of them, but the progress that they had made needed to be rewarded.

“I promise I won’t knot inside you.” Kara asserted with just a touch of desperation. She was like an addict in rut, and her need for Lena brought a vulnerability with it that she tried to hide.

The girl of steel possessed enough willpower and integrity to withstand almost anything, but Lena had reservations when it came to her pussy. She trusted the alpha about as much as she would trust herself in heat. 

She would have to hold firm and make sure Kara obeyed her demands to pull out before it happened. The idea of that appealed to her on a sexual level and she smirked as Kara massaged her feet with dedication to please her. 

The moans that slipped past her lips were well earned by Kara and Lena took the liberty to part her thighs for the alpha’s gaze. It was thrilling to watch the alpha’s eyes darken, and Lena slid a single finger between her pussy lips to spread them. “Rule two; you can only come inside me. I don’t want to leave the bedroom a sticky mess and I like these sheets.”
 

It was a flimsy excuse to exert control in a way that would drive them both crazy, but Kara nodded without hesitation as if she was hanging on her every word. “You can’t be loud. We still have guests and I’m supposed to be napping.”

It was a bullshit rule considering Lena soundproofed the room because of Kara’s super-hearing, but Kara wasn’t aware of that yet and it was exciting to pretend there was a risk of getting caught. As if anyone would dare walk into her bedroom.


Kara looked like she was ready to pop when Lena traced around her clit and exhaled longingly, “I’ll be so quiet—”


“Good,” Lena cut her off with a sly smile pulling at her lips. “Now listen carefully to the last rule. You stop when I tell you to stop, no matter what.”


“I can do that,” Kara rushed out, her thumbs eagerly rubbing along the arch of Lena’s foot as she stared at her cunt.

Lena was tempted to keep her on edge for a few more minutes, but Kara’s erection looked ready to burst through the designer jeans. She chose to show mercy by pulling her dress up and off. She tossed it aside and pointed to Kara’s pants with a sultry command, “Take those off and come here.”
 

After a second of fumbling with the button and zip on her jeans, Kara worked her cock free and gave it a few quick handed strokes. It throbbed a few times, purple around the rim, and dripped viscous arousal that spread over Kara’s fingertips. She tried to wriggle free of the virgin wool sweater and ended up trapping herself for a few seconds before tossing it off.

Lena peered at the garment that was covered in Kara’s pre-cum. “Virgin no more,” She remarked with a wry lilt to her voice, but she barely had time to tease because Kara’s face was between her thighs.  
 

Kara flicked her tongue over Lena’s opening and her groan of delight was so pleasurable it made Lena’s toes curl. The alpha sucked softly on her clit and then kissed along her pussy lips and Lena’s knees jerked from her sensitivity. They were in tune with each other, Lena’s cunt so slick and hot and Kara’s mouth passionate. Lena felt both relaxed and tense when Kara’s tongue rolled over her clit.

“You’re doing this on purpose so I won’t hold out on you,” Lena huffed out in realization and slid her fingers into Kara’s hair.
 

Her inner omega was a lost cause already, not even half as firm as Lena was when laying out her rules. Lena could see herself agreeing to all kinds of things while Kara was licking her pussy – like moving to a house in some awful rural area outside of National City, or giving their baby an absurd name on Kara’s short list. 

 
“Marry me,” Kara husked against her thigh, and Lena was so preoccupied by thoughts of what she could be convinced to do that she actually moaned out, “Yes.” 

If only Kara’s tongue would stop fluttering over her clit, Lena might have found the clarity to ask for a moment, to breathe and consider such a huge question. The alpha was insatiable and her skill was unmatched as she worshipped Lena with her mouth. She seemed to be humming in excitement, her joy so great that she couldn’t contain it.

 
Lena could feel the added touch of super speed behind every rapid lick and her hips lifted off the bed with a keening groan. “That’s cheating.” She gasped, despite the way her mind was starting to catch up on the impromptu proposal. 

She undulated against Kara’s wanting mouth and tried to keep her trembling thighs from locking around the alpha’s head.

Two fingers plunged into her grasping cunt and Lena turned her face into the pillow to stifle her moans. She came undone as Kara crooked them and rubbed into the velvety spot that made her whimper the most. Then suddenly a cool breeze wafted around the bed and Lena could have sworn Kara opened a drawer but she was still between her legs looking up at her like she might have hung the moon and all of the stars in the sky.

“You’re so amazing, Lena, and I’m so lucky.” Kara whispered into her inner thigh, and Lena tried not to freeze as her brain finally caught up to her reckless mouth.

Oh god, she had said yes. She had said yes and now Kara thought they were engaged, and—

Lena swallowed thickly and brought her hand up to brush the hair from her face, and almost choked when she saw the beautiful, modest diamond ring Kara slipped onto her finger. 

“Kara,” Lena exhaled in a whisper, all the breath in her lungs wheezing out as her ribs squeezed in panic.


“I know I should have asked in a more romantic way,” Kara hurried to agree, and climbed up the bed to nuzzle into Lena’s neck as she confided, “But I’ve had it for weeks now and at least I was on my knees.”
 

Laughter stuck in Lena’s throat, because she wasn’t sure if it came from happiness or anxiety. She clamped her lips shut and stared up at Kara, who was gazing lovingly down at her.

“When I found out that you didn’t expect me to actually claim you, I felt awful but I didn’t regret it—well, I mean— I did regret it, but not the—not the spending my life with you part.” 

Kara paused with a small smile turning up the corners of her lips and adoration shining in her eyes. “I know some couples don’t care about marriage, but I thought maybe, if I asked you, and gave you the choice to pick me in return…” She trailed off, her smile radiant as she pressed soft, warm kisses against Lena’s cheeks, “That you would. And you did.”

 

Lena could have blacked out from the stress and overwhelming joy of it all. She placed her hand on Kara’s shoulder and took a deep breath to inhale rut pheromones. 

 

“I did,” Lena whispered and her lower lip trembled as she corrected herself, “I do. I choose you.” Her smile broke just as it formed and she reached for Kara, pulling her close and kissing at her neck.
 

It seemed like all of the good in her relationship with Kara came from mistakes and misunderstandings and Lena didn’t know how to express herself verbally, so she handled the situation by opening her legs. 

 
The familiar stirrings of worry and dread started in her stomach, but Kara stopped all of it by thrusting her cock inside of her.

They connected so perfectly and Lena moaned encouragements into Kara’s ear, “Yes, fuck me. Lay claim to me all over again.”

She found herself wanting to break her own rules, to allow Kara to be rough and loud and cover her in seed. The alpha rutted into her with forceful and quickening thrusts. Kara’s cock felt so good deep in her cunt and her clit throbbed as Kara’s pelvis slammed into it. 

Kara quieted her soft groans by biting and kissing along Lena’s neck and shoulder, and she put her whole body into every thrust she gave. She was restrained in her display of power, careful with the way she held herself up so that her toned abdomen barely caressed over Lena’s swollen belly as they moved together.
 

For all the force she used to plunge her cock into Lena’s reddened, slick hole, she matched in tenderness with her hands as they roamed over Lena’s tender breasts. She kissed them as if bestowing promises, her lips capturing the stiff and aching nipples to lavish with her tongue while her palms stroked over Lena’s pregnant belly.
 

It would never cease to amaze Lena that her alpha could simultaneously be rough and gentle, and she moaned from it as Kara caught her by the knees to push her thighs wider apart. 

From the slack jawed appreciation on Kara’s face she knew the alpha was indulging in the sight of her thick cock spreading her cunt.

“Describe it for me,” Lena breathlessly requested, her hands palming her own breasts as she rocked into her mate. “Tell me what you see, why you love watching as you fuck me.”
 

Kara penetrated her deeper in excitement, her soft exhales interspersed with moans she fought to conceal as she whispered, “You’re so beautiful like this, blushing pinks and red, covered in slick, Rao, so much of it you look juicy, like I need to put my mouth on you again just to taste—”

 
Evidently just saying it aloud was enough to convince Kara to give into her urges because she pulled out to dive between Lena’s thighs.
 

Kara was fully in rut now, her skin was peppered with sweat and her appetite for Lena was all consuming. She no sooner started to tongue her entrance then she was on her knees and pushing back inside her cunt with a loud groan.


“I love you,” Kara was uttering under her breath, her hands gliding up Lena’s inner thighs and over her belly as she slammed into her faster.

 

“Are you thinking of knotting and getting me pregnant again?” Lena’s tone was deliberately provocative, but she could sense the fantasy in Kara’s mind as her inner alpha began to plan for their future.

It was meant to spur Kara’s release, but Lena’s omega reacted just the same and her cunt went into sudden spasm as Kara thumbed at her clit. She arched from the pleasure, her hands grabbing for Kara’s arms to hold on as the alpha forced her cock through her rippling muscles.
 

 The first throb of Kara’s shaft sent a thick blast of seed into Lena’s cunt, and she whimpered as Kara buried her cock in deeper.

“Stop, don’t knot inside me,” Lena blurted in a rush as her cunt tried to contradict her by tightening around Kara’s length.
 

Kara gave a pained groan as she stilled her hips, her body jerking as she pulled out so her knot formed outside of Lena’s cunt. She spilled warm seed into her hot channel then sat back with a still throbbing erection.

Without the tight warmth of Lena’s pussy, and no stimulation, Lena watched as Kara’s knot began to soften at a much faster rate. She tugged Kara forward before the swelling fully eased and allowed the alpha to plunge back inside of her. It stretched her tight entrance and Lena worked her inner muscles over it.
 

“Lena,” Kara whined pathetically, her teeth snapping shut at the last second as she hissed between the white rows. She was losing herself to her rut, but Lena stared into her eyes and continued in defiance.
 

The demanding warm pulsations of her cunt pulled another hard jet of seed from Kara and the alpha bit back a groan as her hips picked up momentum. Lena could see the shift in Kara and the moment her alpha fought for control. It caused such frustration that Kara bit viciously down on her own lip to resist her urges.
 

“Lena, if you keep doing that, I am going to knot,” Kara groaned and pounded into her with quiet growls that couldn’t be contained any longer. Her greedy hands snared Lena’s hips to force her into every rapid thrust to sate her baser needs.
 

“You’re not allowed,” Lena wickedly reminded her and clenched her cunt all the more just to feel the way Kara strained in her efforts to honor her promise.

She wasn’t sure where the bout of strength came from, or what possessed her to shove Kara back so that she could straddle her hips, but the surprise on the alpha’s face as she landed on her back said she hadn’t expected it either.

“You’re going to do exactly as I say,” Lena informed Kara as she crawled over her. The seductive rasp of her words wrapped around Kara along with the scent of her pheromones. “When I say it.” She asserted, her lips hovering over Kara’s as she sank down to take all of her girthy cock in one go.

Kara exhaled a breathy moan and Lena smirked as she leaned down to whisper against the alpha’s mouth. “Behave, or I’ll revoke your rights to be inside my pussy for the rest of the night.” She promised, the tip of her tongue tracing Kara’s lower lip before she sucked it into her mouth.
 

The alpha uttered something garbled in Kryptonese that Lena took as eager agreement, because Kara was quick to nod as she sank heavily into the bed.

Lena used Kara’s shoulders to steady herself and kept her down as she began a sensual grind. Her soaked folds were snug around Kara’s half formed knot and Lena took immense pleasure in seeing the euphoric glint in the alpha’s dark eyes when she clenched her cunt in quick pulses.

The tendons in Kara’s neck surfaced under the skin as she tipped her head back and grabbed for Lena’s hips to try and keep herself buried in deep. “Rao, I’m gonna—”
 

“Not yet.” Lena warned sharply, rubbing her cunt faster as she began a fast bounce. The sloppy sound of her filled hole was erotic to her own ears and she moaned as she stimulated her clit with the back and forth motion. “You’ll come when I say you can. Now fuck me. I know how long you can last, even in a rut.”
 

The words were barely out of her mouth as Kara pitched her hips up to buck. She drilled into Lena’s slick cunt frantically, her thighs colliding roughly with Lena’s, changing her delicate porcelain skin to a blushing pink with every hard thrust.
 

“That’s it,” Lena encouraged, her hand tangling in Kara’s hair to hold her head up, while she palmed her breast with the other. “Watch my pussy take every inch of you.”
 

They both forgot to be quiet as Kara groaned and pumped her hips. Lena rode her fiercely, unapologetic as she fulfilled her carnal needs with an almost selfish desire to get off. She could feel the climax building like a storm within her, and her nerves crackled with pleasure while the muscles in her cunt tightened with delicious pressure. The smack of her ass slamming into Kara’s thighs pushed the alpha’s cock into her deeper and she felt a knot forming as she cried out.
 

She had never been one to have gushing orgasms but there was no denying her cunt was wet. Slick poured from her stuffed cunt to soak Kara beneath her. 

Lena didn’t give Kara the luxury of finishing as slid off her cock at the last second to stop her knot from taking hold.

“No, no please,” Kara whined, the stench of her desperation overbearing as she scrambled to hold onto Lena’s hips to try and bring her cunt closer. “Lena please, I’m so close, I need—”

“Shh, put your hands behind your head.” Lena instructed, settling herself on Kara’s thighs with her giant knot trapped against her pussy lips. “Should I soothe your aching cock with my cunt, Kara?”
 

Lena didn’t wait for an answer, and with a sensual glide, rubbed her heated cunt over the wide bulge at the base of Kara’s cock. 

The alpha moaned deliriously and rocked forward. “Yesss,” She stressed in a whisper, unable to control the way she rubbed her knot between Lena’s glistening folds.

 
Kara’s cock was so thick from her rut, and her knot was exceptionally large. Almost too big to fit inside Lena’s cunt, and her pussy lips were barely able to spread around half of it as she teased it with her silken warmth. 

“You look like you’re ready to come,” Lena remarked coyly, enjoying every stuttered grunt and growl that escaped Kara as she breathed.
 

Lena shifted to lie on her side, with her face scant inches from Kara’s cock. 

“How long can you last like this?” She seductively purred, and opened her mouth to lightly suck on the knot. It was scorching and throbbed against her tongue. The heady scent of Kara’s arousal mingled with her own perfume and Lena moaned as she licked at the thick bulge.
 

“Oh-oh Rao,” Kara whimpered, writhing as if she was caught between pain and pleasure, her heels digging into the mattress as she tried to push her cock into Lena’s face “Yes, use your mouth, please—”

 
She had never sucked on a knot before, but running her tongue over it seemed to be driving Kara mad and Lena wasn’t about to stop. She pulled it into her mouth and let it pop from her lips until Kara’s pleading became almost unintelligible and a drizzle of creamy seed leaked down her shaft.
 

“Uh uh, you know that’s not allowed,” Lena teased, using the tip of her tongue to lick up the droplet from base to tip. “You can only come inside me.” She reminded the alpha then swirled her tongue around the swollen purple head of Kara’s cock.
 

Lena clasped both of her hands around the slippery knot and massaged it until the alpha jerked and whined.

Rivulets of seed poured from the groove of Kara’s cock and Lena chose that moment to fully wrap her lips around the alpha’s shaft. She sucked roughly, taking as much of Kara into her mouth and throat as she could with such intensity that the stimulation overwhelmed the alpha.
 

Kara hissed and groaned and begged for more, and Lena gave it to her, sucking hard enough to make her jaw ache. She worked her lips and tongue along the underside of Kara’s shaft and when it stiffened like steel and Kara tried to thrust into her mouth, Lena pulled back just to see the way Kara struggled not to come.

 
It must have been the last shred of her self-restraint, because the alpha let out a growl that did incredible things to Lena. Her cunt fluttered in expectation as Kara suddenly grabbed her and flipped her onto her hands and knees. 

Lena’s omega reacted instinctively and she stretched forward into a low bend to present herself to Kara’s lustful gaze, and groaned when the alpha slammed her cock roughly into her cunt.

It had been a while since they were completely ravenous for one another, and they had never experienced it without any negativity brewing under the surface of the relationship. 

Lena had put her rules in place for a reason, to keep the sex quick and return back to the party before everyone thought they were rude, but she knew it was hopeless as Kara rocked into her. They needed this, and not just because of raging hormones and Kara’s rut. 

The fast glide of Kara’s cock through her cunt was so pleasurable that her inner thighs were shaking. Her head fell forward with Kara’s thrusts, and she made the most satisfied noises.

Kara pushed into her and forced her down in the bed as she took the hard rutting. The alpha’s deeply aroused groans should have been warning enough that she was about to come. It happened suddenly, and spilled out of her as Kara pulled back to avoid knotting. 

“You broke the rules,” Lena scolded in a quiet voice and ran her fingers through Kara’s seed. She used it to rub between her pussy lips and over her stimulated clit. 

“You want me to stop, or break some more?” Kara husked, her fingers biting into Lena’s hips as she forced her thick cock between her swollen pussy lips to rub Lena’s aching clit.

Hot jolts of pleasure coiled low in Lena’s abdomen and she whined as her cunt spasmed. She should have put an end to it before they got out of hand. There was an entire room of people eating cake and chatting while they waited for her return, but all Lena wanted was to be fucked raw until she couldn’t walk.

“Don’t stop,” Lena whined, inhaling the intoxicating scent of Kara’s pheromones. She stretched out, her hands splayed over the sheets and groaned into her pillow when Kara hammered into her tender cunt with rapid, full thrusts. The sound of her overflowing cunt would linger in the back of her mind for days, reminding Lena of how desperately she needed Kara to take her. 

It was beyond naughty to do this in the middle of their party while her guests were oblivious to how greedy she was for Kara’s cock, and the more she thought about it, the wetter she got. 

“Fuck me harder,” Lena gasped, rocking into every rough smack, “I want to feel you deep inside of me.”

With that green light, Kara’s thrusts picked up even more speed and her hands moved to Lena’s sides to pull her back. Pleasure spread through her cunt and lower abdomen, leaving her trembling in strong release. Just when she thought the sexual high would wear off, her inner walls tightened around Kara’s cock in another body-rocking spasm. She whined from the unexpectedness of it, and Kara rubbed her to make it all the more powerful.

The advantage of sound-proofing the room was that no one could hear her ragged moans—not that she was concerned about being loud when she was coming harder than she ever had in her life. 

Kara’s knot was developing, sinking into her cunt, and Lena was still in a state of checked-out bliss. Her hair had waves and curls in it and stuck to her mouth, where her lipstick was an absolute mess.  The heat of the knot was what finally got her attention and she lifted her head to glance back at Kara. 

The alpha’s orgasm hit after the knot stuck and Kara held onto Lena’s hips for what felt like more than a minute until her cunt was full of seed. 

Kara was gentle in settling down next to her, and she looked so satisfied that Lena merely pulled the alpha’s arm around her. 

She could feel the throb of Kara’s cock, still gradually releasing seed with every flutter of her silken cunt. The bliss passed between them freely, a connection they shared that went beyond the physical, and when Kara’s hand caught her chin to tilt her head back, Lena could do little more than moan when the alpha claimed her lips in a sensual, slow kiss.

It matched the lazy way Kara’s fingers traced down her jaw and over her tender breasts. The alpha pinched her nipples lightly, enough to make Lena’s breath hitch, and then on they went, tickling over her ribs and following the swell of her belly to dip low between her drenched thighs.

"Kara,” Lena whimpered, so sensitive and spread open by her mate’s huge knot.

“Please, one more time.” Kara encouraged, her sultry tone as smooth as her warm palm that curled under Lena’s thigh to lift it up and hang it over her muscled forearm. The alpha’s fingers rubbed soothingly over Lena’s puffy, cherry red cunt, smearing seed over her heated labia before delicately strumming her swollen clit.

The barest of touches sent shockwaves of pleasure through Lena and she whined as her hips jerked and her inner walls clamped tighter around Kara’s immense girth. The breath in her lungs stuck, and a stuttered moan escaped her a moment later as Kara rocked gently into her, slow but insistent as she lost control of herself and shuddered to another climax.

Kara groaned in satisfaction, the hot squeeze of Lena’s inner walls forcing more seed out of her shaft and Lena whined at how full her cunt was in the moment.

One more time turned into four, with Kara lovingly kissing and lightly biting at her neck, and Lena was so overwhelmed by the sensations of being worshipped that she forgot about time, and the party, and that she was supposed to be napping and not having mind-blowing sex with a very insatiable Kryptonian who possessed enough stamina to go for days.

She did end up falling asleep, with Kara’s arms wrapped snugly around her, protective and possessive as she nuzzled into her from behind. Lena kept the alpha’s cock warm by refusing to let Kara pull out, even when her knot began to soften, and it was only once she woke up that she remembered everyone was waiting.

“The party,” Lena blurted, her head swinging around towards Kara as she exhaled, “Oh god, everyone’s—”

“Already left to let you rest,” Kara murmured into Lena’s shoulder, her grin carrying in her tone. “I might have texted Alex to send them all home.”

“You might have?” Lena choked out in exasperation. She wasn’t sure if she should feel scandalized or impressed that Kara at least had the good sense to get everyone out while fucking her senseless. “You couldn’t have told me this before I set out my rules?”

“And ruin all the fun of breaking them?” Kara quipped, securing her arms around Lena as she raised her eyebrows.

“Well, you owe me at least two dozen glazed donuts in the morning and an endless amount of foot rubs for that very sneaky Luthor behavior, and then maybe I'll take care of your rut.” Lena taunted with a playful smile. She fully intended to take care of Kara, and the alpha knew it, but nuzzled into her to try to placate her anyway. 

They were content to cuddle and exhaustion pulled Lena into a drowsy state. It lasted until Kara received a text and Lena felt the instant tension manifest in the Super. 

“Hey, Lena, I need to go,” Kara muttered against her neck and reached down to rub her side. “There’s—uh, something happening downtown. You going to be okay here?”

“No,” Lena snapped with genuine rage this time. “You’re really going to try to fly off without even telling me what’s going on?” 

Kara was already activating her glasses and her super suit appeared, beginning its slow spread over her arms and legs. “I — I won’t be gone long,” She reasoned and flailed as she tried to justify the split second decision not to include Lena in resolving whatever budding crisis the city was facing. 

They had never actually discussed how Lena’s involvement with Kara’s superhero duties would change now that she was pregnant, and Lena took full offense to the alpha’s way of handling it. 

“Two hours, tops,” Kara reassured her and stepped towards the window before Lena managed to complain. “Please, stay here. For your own safety. For the baby.” 

Kara gave her a pleading look that was such a guilt trip in and of itself. She rushed out onto the balcony and then flew off before Lena had even taken a few steps to follow her.
