Big Dick Energy - Chapter 3

+Size kink, rut sex.


 

Kara learned two important things over the lust-fueled weekend she spent with Lena. The first was that they were as insatiable as each other and she didn’t have to feel embarrassed when she woke up with an erection.
 

Lena caught Kara trying to hide it and explained that she often woke up with her panties covered in slick, then took great delight in proving it to Kara. They had sleepy morning sex two days in a row and Kara hoped that it would be something they always did together.

 

The second thing Kara learned was that Lena liked it when her alpha initiated, even if it was something as simple as squeezing her backside or, in the middle of making out, placing Lena’s hand over the tent in her pants to let her know just how much she wanted her. It was intoxicating, seeing the way Lena responded to her in those moments, and Kara decided that she would try to be bolder. She hadn’t quite worked up the courage to say anything dirty yet but she had the feeling that Lena would like it if she was more direct and in control.

Kara planned to try it out during their date after classes, but when she awoke on Monday, she didn’t feel as fresh as she had hoped.

 

Groggy and a little fevered, Kara had thrown on clothes and grabbed her backpack with the belief that she could shake it off — except, as the hours went by, Kara felt progressively worse. She had no appetite for food, despite the way her stomach grumbled furiously. She shivered so much that someone asked if she had the flu. Kara would have thought that herself, but the flu usually left her head foggy. While she was finding it hard to concentrate on academics, her mind was very alert and very focused on Lena. More precisely, having sex with Lena.

 

Kara could barely hold a pen without trembling, and even then her mind went to Lena’s hands, and how delicate and soft they were and how wonderful they felt when wrapped around her cock.
 

It wasn’t until her first class ended that Kara realized she had been sitting at her desk with an erection, and even the rush of fear that shocked her system didn’t reduce it. She was the last out of the classroom and she ran to Alpha Studies with her bag in front of her.

 

The exertion of bolting across campus should have made her arousal go away, but as Kara slid into her seat, she could still feel it pushing against her pants and the sweat on her forehead wasn’t from sprinting because she wasn’t even breathless.

 

Kara shook where she sat, her books and pens rattling as she tried to hold still. It felt like her skin was being fried, and her clothes rubbed her raw until the soft cotton stung along her arms and she had goosebumps so hard they were like sand beneath her skin. She needed Lena.

 

Kara couldn’t explain how she knew that but every part of her being sang with it, an intrinsic conviction that defied logic.

 

It wasn’t until she looked up that she realized Professor Grant was staring straight at her with a scrutinizing look on her face that had Kara gulping nervously as she twitched in her seat and tried to slump lower.

 

When everyone else had filed into the class, Professor Grant finally strode to the board and declared sharply, “Today we’re going to discuss Heats and Ruts, the latter of which will apply to all of you. Rest assured, you can take suppressors to alleviate the torment of Ruts, and should you find yourself in need? Come to me, I have a stockpile for students.”

 

“Why the hell would anyone take suppressors when they could just…” Maxwell Lord trailed off with a laugh.

“Enjoy the ride?” Professor Grant rolled her eyes, then slapped her chalk down so hard it shattered on her desk. “This is why we have so many students afraid to seek help. Idiotic attitudes like that will leave some people suffering needlessly, Maxwell. Let me tell you something. Whatever you think you know about ruts, you’re wrong. It’s not just an excuse to sleep with someone. Even in relationships, ruts can be brutal and painful experiences. Try having an erection that won’t go away for days on end, no matter how much you use it, then tell me how much fun you had with it afterwards.”
 

Kara’s eyes widened and Maxwell coughed, evidently at a loss for words. The rest of the class fell into a somber hush and Professor Grant exhaled a heavy breath and paced at the front of the room.

 

“I know where your minds go whenever someone mentions these things. You grin and joke about how titillating it will be until all you can think about is breeding, but this is no laughing matter.” Professor Grant glared at all of them, but her eyes lingered on Kara, softening slightly before she continued matter of factly, “Ruts share some similarities with Heats. Both can last for up to five days, both cause a loss of appetite and both can cause an almost manic state where you won’t even be able to sleep because your body is in the stages of such extreme need that your muscles ache and you can barely function. You will crave sexual gratification above all else, including your own and your partner’s health and safety.”

 

Kara didn’t like the sound of that and she pressed her lips together and tried to appear smaller so as not to draw attention to herself. Though nobody else was staring at her, she couldn’t help but feel singled out as Professor Grant’s eyes flicked onto her once again.

 

“I’m sure the idea of having sex continuously doesn’t seem terrible to any of you, but all that friction can do serious damage. During this time, you lose an integral part of yourself, and you become more animal than human. That’s not an excuse to act as you please.” Professor Grant pointedly stared at Maxwell, who let out a grunt of annoyance, but didn’t dare open his mouth to say something stupid. “When an omega enters a Heat, they are at their prime for becoming pregnant, and when you enter a Rut, you’re more virile. Your scent will be more potent and you might find you get extra attention from others because of it. Take precautions, because those are the riskiest times to engage in intercourse.”

 

Kara was even more grateful for the basket of condoms she had won. At least that was one thing she didn’t have to worry about for the foreseeable future.

 

“I thought getting it on really helped ease it.” Mike called out from the back of the class, and Professor Grant pursed her lips together. “You know, scratches the itch and all that.”

 

“On rare occasions, you may simply exhaust yourself with sex to the point of passing out, and then awaken to find your Rut has finally passed, but those incidences are few and far between. To anyone stupid enough considering it, don’t.” Professor Grant snapped, unamused by the way a few of the alphas snorted at her warning. “That being said, having someone in a time of need certainly helps, but you shouldn’t become dependent on that. Suppressors, for the most part, will reduce your swelling and your baser urges, but you will still feel them, albeit far less intensely. They make the rut manageable, instead of all-consuming.”

By the time class ended, Kara was still fidgeting in her seat, pretending to put things in her bag while everyone else fled. When Kara worked up the courage to finally stand, she held her bag in front of herself again, but before she made it to the front of the room, Professor Grant set a pill bottle on the edge of her desk and gave her a meaningful look. Wordlessly, Kara snuck them into her pocket, and Professor Grant murmured just as Kara was halfway out the door, “Two in the morning should get you through your classes, two at night should let you sleep. If you need more, you can reach me through email.”

 

Kara stumbled over her attempt to say thank you, and then rushed back to her dorm as fast as if she was late for an exam. She was soaked in sweat and Lena would be stopping by in half an hour to go on their date.

 

Kara set the bottle on her desk and hurriedly showered to get rid of the stench that clung to her. She had just about finished getting dressed when she smelled the subtle perfume of Lena’s pheromones. Groaning quietly, Kara’s hand went to her waist as if it physically pained her, and she noticed, quite alarmingly, that there was a small wet patch forming in the tent of her pants.

Lena knocked a moment later, and Kara yelled, “Just a minute!” as she scrambled to change her trousers. She pulled on a tight fitting pair of shorts, then another pair of trousers, and was pleased to see that there wasn’t an obvious bulge showing. 

Lena came to a sudden stop in the doorway and raised her eyebrow at Kara, already in the thrall of the rut pheromones in the air. She closed the door, unzipped her outer coat and then stepped into Kara’s arms like she intended to stay in all night.

“Kara, you seem different today,” Lena remarked, as if she couldn’t quite place what had changed about her, although the scents in the room were enough of a clue for her to figure it out right away. “Are you in a rut?”

With a wicked and dimpled grin, Lena lifted skirt to show off a thin lacy strip of fabric she wore between her legs.

“These are new and I was hoping to wear them for you when you went into your first rut,” Lena announced, unaware of how the sight of her exposed body made Kara’s cock throb with a terrible arousal.

“I’ve been reading about ruts on my own time, because Professor J’onzz treats us omegas like we’re all delicate flowers, and won’t discuss it until we’re finished with our unit on safe sex,” Lena added, moving towards the desk where she rummaged in the basket of condoms Kara had won. The rut aromas seemed to be getting her excited and Lena’s face glowed with a rosy blush of desire.

Lena tugged a small spray out of her pocket and held it up so Kara could glimpse the label.

“Professor J’onzz handed this out today,” Lena explained and unwound the top of the spray so that Kara could get a whiff of the strong and foul-smelling substance. “He’s basically turned the Omega Seminar into a self-defense class. It’s supposed to calm alphas down when they’re too aggressive.”

The putrid smell only seemed to affect Kara and she sneezed, then coughed roughly and stepped back from Lena with a hand protecting her mouth. She sniffed harshly and she couldn’t pick up on Lena’s pheromones, but it didn’t lessen the throb in her pants.

 

“It’s good that he’s teaching you self-defense,” Kara coughed. “I — I think Professor Grant told us about ruts today because of me. She warned us that it — it can get pretty bad and that taking these pills should help with it.” Kara grabbed the bottle of suppressors and gave them to Lena to take a look at.

“She said two in the morning and two at night, so I figure I can take one now and we can still go on our date.” Kara murmured, but her eyes were roaming over Lena as if she was starving, which she was, but the thought of food was the last thing on her mind as she walked around Lena, unaware that she was even appraising her in such a blatant way. “You look so good, Lena. I can’t wait to walk with you on my arm.”

It was a phrase that Kara hadn’t considered saying, but it rolled off her tongue smoothly and she leaned in to sniff at Lena’s neck with a low rumble. Lena’s scent was so faint that Kara found herself pressing her nose into the elegant slope of her throat and huffing at her skin, desperate for a fix, but it was clear the spray had somehow desensitized her for the time being.

“How long does that stuff last?” Kara muttered in frustration, withdrawing to look longingly at Lena. It felt like she was being denied something vital. “You’re right here and it’s like I can’t even tell.”

 “Should I toss it out the window?” Lena asked and went over to open the blinds, but as soon as she cracked the window, the lingering scent of the spray went back out with the chilly air. Her rich and delectable omega fragrance seemed twice as strong when the other reek had fully cleared out. 

Kara stopped Lena from completely discarding the spray, because in the back of her mind was a deep-seated worry that the omega might need it if her rut was as awful as Professor Grant claimed it to be. 

 

Lena held the bottle of spray out in front of her and glanced over the label, then tucked it away in her bag. “Really, I won’t be needing this when you’ve practically claimed me already,” she softly argued and touched the necklace around her throat reverently while she stared at Kara. 

The rut pheromones could lower the inhibitions of an omega drastically, and as Lena breathed in deeper, she laughed out, “Your rut is certainly strong, isn’t it? Maybe we should just stay in tonight so I can take care of you.”

Kara fixated on Lena’s fingers as she toyed with her necklace. A perverse and overwhelming sense of ownership had her biting the inside of her cheek to try and snap out of toxic thoughts and she wondered if being stuck in the same, small space was fueling the rut more.

“I think this is just the start of it…” Kara reflected, and a sudden urgency to get out of the room compelled her to grab Lena’s coat and shake her head. If they stayed in, she would never want to leave, and Lena deserved a night of romance that didn’t involve secluding her in a cramped little room. “How about we go to the restaurant and if it gets worse, we can just come back after that?”

It sounded like a fair compromise, even to her own ears, but Kara was taking deeper, greedier breaths to inhale the scent of Lena like she was a vaporized drug.

 

“Please, I got us reservations at the nicest Italian restaurant not far from campus.” Kara managed to stammer out, in between snorting Lena’s addictive scents.

 

Kara had also ordered a bouquet of roses to be delivered to the table and if they didn’t leave soon, Lena wouldn’t be there to get them. She zipped Lena back into her coat and dared to press a kiss to the corner of her mouth. It was a taste of what she wanted most, and she trembled where she stood, completely focused on Lena, the thought of the suppressors a distant memory.

 

Kara ushered Lena through the door before her resolve caved. This would be their first real date together, if Kara discounted all of the parties they went to in the last few months, and she wanted it to be unforgettable. The rut-crazed part of her mind knew that sex was almost assured after this romantic night out, and Kara stopped in her tracks as she experienced a little self-disgust over that thought. Their date night should have nothing to do with sex and everything to do with Kara’s hopes of making Lena feel special. 

Lena noticed she was no longer following her and turned around to check on Kara.

 

“You really don’t seem to be feeling well,” Lena noted and pressed her smooth and cool palm against Kara’s forehead. “Maybe I shouldn’t have encouraged you to come out."

Even that comforting touch was arousing and Kara stumbled back like Lena had just smacked her. 

“Nu—no, Lena — I’m swear, I’m totally fine,” Kara stuttered and forced a smile on her face to compensate for how her eyes strayed right to Lena’s cleavage. 

“What was I just saying to you then?” Lena challenged and raised her eyebrow, which was sharper than a weapon and just as effective a threat.

Kara hadn’t heard a single word Lena uttered since they left her dorm room, so she fidgeted and stuttered “uhhh—um,” and then took her best guess. “Class? You were telling me about Omega Studies.” 

Luck was on Kara’s side for a change and Lena merely narrowed her eyes, as if she suspected the alpha was lying, but had no way to prove it. 

 “I was telling you what I read about Ruts in the library book I checked out,” Lena confirmed and looped her arm with Kara’s as they strolled out of the building and in the direction of the restaurant. “I doubt we’ll study them for months. I swear, it’s like Professor J’onzz doesn’t even want to mention alphas in our presence.  When he saw my necklace, he seemed concerned that some alpha was just taking advantage. I was sure that he would launch into a lecture and turn it into a teachable moment, but then Andrea announced that you were the alpha who gave it to me and he let the subject drop. He must like you.”

“I’ve had some classes with him, but he was like Alex’s mentor, so I guess he must trust me.” Kara mumbled distractedly as they wandered across campus.

 

The sky was dark, but she could see the way heads turned as she walked by, and she wasn’t entirely sure if it was because of Lena’s omega scents or her own potent pheromones. Either way, she felt torn between owning it and hating it, and the result was a half-hearted confidence interspersed with mild paranoia that had her shoulders straight and her eyes darting around. Kara checked the people around them, then glanced towards her crotch, peered over at Lena’s breasts, her face, and then back to Lena's breasts like it was some kind of nervous tick.

 

Sweat prickled her brow and she realized that she was breathing far too heavily for a leisurely stroll. Flashing lights brightened up the campus and bathed everything around it in a neon glow and Kara tried to focus on them instead of the urgent throb of her cock begging her to find a way to get it inside Lena as soon as possible.

 

They were across the street from the restaurant when Kara recognized she had made a huge mistake in coming out, and her hand absently went to her pocket for the suppressors that weren’t there.

 

Panic swelled in Kara’s chest, an invisible balloon that stopped the air in her lungs as she turned towards Lena with a moment of frenzied clarity and blurted, “Lena I forgot to take the suppressor before leaving. I should really go back and—”

 

Lena secured her arm through Kara’s with a determination to soothe her. 

“You’ll be fine,” Lena promised and pulled Kara across the busy road before she could think of ways to protest or stumble into the oncoming traffic. “Do you really think taking a suppressor will be necessary when I’m in your bed practically every night? It’s my duty as your omega to see you through your ruts. Let’s get some food in you and then we’ll go right home.”

If not for how Lena guided her into the restaurant and spoke to the waiters on Kara’s behalf, she would never have made it to their booth. Her entire body flamed with desire and although she gulped down ice water, she knew the only way to quench her need was through Lena. 

Lena gathered up the vase of roses on the table to sniff them, but the light floral scent wouldn’t be able to compete with Kara’s strong alpha musk.

The lipstick Lena wore was as red as the petals, and Kara watched her lips move as if in slow motion. She knew the omega was thanking her for the flowers, but Kara’s racing pulse drowned it out and she focused intently on her mouth. The plumpness of her lips, how pillowy soft and warm they must be, how they stretched whenever Lena smiled. Kara was imagining them stretched in other ways, in an act they had never even done yet, and a low groan vibrated at the back of her throat.

 

Lena shot her a curious look and Kara tried to sit still and at least look normal, despite the intensity in her eyes and the way her one-track mind honed in on Lena as if she was a specialized subject on an exam.

“So what else did it say in that book you mentioned?” Kara asked, and picked up the menu as if she cared what was on it in an attempt to redirect her attention.

 

This date was meant to be a way to show Lena how much she loved her, not lusted after her, and Kara was ruining it already with her inability to even hold a proper conversation.

Lena folded and re-folded her napkin, as if she too was struggling to sit still and concentrate. She lifted her menu and peered down at the choices, but she was still craning towards Kara and doing all she could to get her attention back. In the last few days, she had developed the habit of playing with her necklace whenever she wanted Kara to glance her way and she was currently twisting it in her fingers. 

“I read the section on knotting,” Lena confessed as she paranoiacally glanced around and scooted her chair closer. “Specifically, about how well-endowed alphas tend to have larger knots and how during ruts, knots are unavoidable. You’ll need a particular brand of rut condom for the week. I purchased some just in case. What did you learn about all of this in Alpha Studies?”

Kara could barely remember her name, let alone answer questions. Part of her was frightened by the prospect of unavoidably knotting because she could seriously injure Lena, and the other, baser part of her was replaying the images she had looked up when she had done her own research on knotting the week prior. Her current, throbbing erection had her feeling ashamed and conflicted, especially because even at the risk of hurting Lena, she still craved to be inside her.

 

“I learned that alphas in ruts can be a danger to themselves and their partners because we act more like animals. We—we’re driven completely by our desires, to the point where we don’t eat or sleep, and we can have erections that last for five days.” Kara’s words came out so fast because she was afraid if she stopped, she would forget what to say. Her stomach chose that second to back up her claims about eating by grumbling loudly and she grimaced and hunched over as if that would quiet its complaints.

 

Leaning into the table only brought the delectable scents of Lena closer to her nose and Kara sucked in the fragrant perfume. The soft musk that intertwined with Lena’s usual pheromones alerted Kara that the omega was aroused, and even in the confines of the shorts beneath her pants, Kara could feel the tip of her cock leak with excitement. She bit the inside of her lip to try and snap herself out of it, and the slight pain helped momentarily.

 

“I’m scared,” Kara admitted in a whisper. “It’s like there’s another version of me inside my head trying to tell me to take you right here and now, and all I wanted was for this night to be romantic. What if I lose control of myself and hurt you?”

“I know you, and I get that you’re unsettled by all of this, but you’re not going to lose control,” Lena asserted with confidence, but then plucked the menu from Kara’s trembling hands. “I think we should come back some other time when you’re feeling more yourself. Let’s get you home now and into bed.”

It should have been easy to put her arm around Lena and let the omega lead her from the restaurant, but they both seemed to instinctively sense it was the wrong move.

 

Their hormones demanded action and Kara gave a fleeting glance around the restaurant in search of a private place to relieve some of their sexual tension. 

Lena managed to drop a few bills onto the table to pay for the waiter’s inconvenience and then she lifted her bouquet of roses.
 

In a daze of agonizing arousal, Kara stumbled out of the restaurant and across the road with Lena.  They didn’t make it far before Kara pulled Lena into an alley and pressed her into the alcove of some building.

 

They were barely out of sight when Kara whispered pleas against Lena’s lips. Her mouth was demanding as she captured Lena’s and pushed her tongue into the wet warmth just to taste her. Kara’s groan was nothing short of erotic and her hands were everywhere, simultaneously trying to feel Lena up over her coat and guide her hand to the concealed bulge in her pants. “Please, Lena, please touch me. I – I need you so much that I can’t take it.”

 

Her urgency wasn’t just in her actions. The potent, overpowering scent of her pheromones were enough to drive Lena into a frenzy of her own and the omega moaned provocatively and almost dropped her flowers.
 

“Wait,” Lena whimpered, tearing away from the kiss to hold Kara back. “I have an idea. Just give me a second.” She murmured, her tone syrupy as she set the vase down safely and opened her jacket to show off her supple figure.

 

“Hold my jacket around you.” Lena insisted with the kind of tone that sent enticing shivers through Kara.

 

With her hands occupied by holding the thick fabric, it provided a modicum of privacy as Lena’s delicate hands unzipped Kara’s pants and pulled them down along with her shorts to free Kara’s erection. It bounced in the space between them, heavy and profusely dripping excitement.

 

They both moaned for different reasons, Kara in relief, and Lena in lust as she lifted her skirt up to tuck it into the waistband, exposing her pale thighs and lacy panties.
 

“Let me take the edge off, and then we can hurry back to your room so I can properly take care of you.” Lena lilted, her eager hand wrapping around Kara’s thick shaft. She smeared Kara’s precum over her palm to make it a smoother glide as she pumped her fist. 

Kara rocked her hips to increase the friction, the slick noise offset by her heavy breaths as she trembled and stared at Lena’s pretty lace panties and her soft, warm hand as it moved furiously over her cock.
 

“Oh-oh god—” Kara husked when Lena rolled her palm over the sensitive head of her cock to gather up the sticky arousal that leaked from the tip.

“You like that?” Lena asked seductively, and did it again just to watch the way Kara bit her lip to stifle a moan. She swayed where she stood and Lena grabbed the front of Kara’s shirt to hold her steady as she stroked her faster. “That’s it Kara. You’re so close to making a mess of my thighs again. I think you like seeing that.” Lena squeezed her hand a little tighter and Kara whimpered, bucking harder, her hips stuttering as pleasure coiled like a spring ready to release.

“You want to know something?” Lena asked, her breathy tone giving Kara goosebumps. “I like it too.”

“Lena--” Kara gasped, a throaty groan the only warning to signal her orgasm as her hips suddenly jerked forward and her cock pulsed opalescent pleasure. Warm spurts coated Lena’s thighs and panties, and some even covered the underside of her skirt. Lena coaxed the last few drops out of Kara’s shaft by giving it a few extra tugs. 

Kara fell against Lena, trapping her against the brick wall at her back while they both huffed in barely restrained excitement for each other. 

“We need to hurry back to your room now,” Lena muttered and hastily fixed her skirt, not bothering to wipe up any of the come that was rolling down her legs. The whole point of this messy fumbling was to satisfy Kara’s libido, but she only became more insufferably hungry for Lena and more eager to rush back to her dorm. 

Kara caught herself running her fingers through the thick wads of her seed with the strong urge to rub some of it into Lena’s pussy or otherwise push it inside of her. The animalistic, alpha part of her brain had taken over with the imperative to breed.  
 

Lena’s panties would be so easy to move out of the way, but the omega hurried around her and Kara’s rational side snapped her out of those crazy, rut-induced thoughts.   

Fortunately for Kara, she seemed to have avoided knotting in public, but her cock was still swollen beyond its usual size, and when they entered her dorm room, it had yet to shrink back to its normal girth. 

Lena had the good sense to step into the bathroom to take off her clothes, and Kara shed her trousers before flinging herself down in bed. It took a lot of effort to wriggle out of her boxers and shirt, but Kara managed it before Lena appeared naked in the doorway. 

The omega took in the sight of her erection with hesitancy and bit down on her bottom lip. 

“Kara, I know you want to be inside of me right away, but we’ll have to take it slow,” Lena advised and waited until Kara met her eyes before she drifted closer to the bed.  

Lena was still getting accustomed to having sex with an alpha, and even under normal circumstances Kara needed to be careful. The rut only complicated the situation. 

 

Kara shook imperceptibly on the bed, her body a fault line gearing up for an unstoppable quake. She understood on a deeper level that this carnal part surfacing was the very nature of an alpha that lay dormant the rest of the time.

 

She had never felt such a voracious, unending hunger before and she could smell the traces of worry that mingled with Lena’s arousal like smoke permeating the air. She needed Lena like she needed to breathe, but if she came any closer she would lose this functioning part of herself that could think and reason beyond her rut.

 

“Wait, I need to talk to you first.”

 

Lena halted by the bathroom door, concern on her face as she waited patiently for Kara to continue.

 

“I don’t want to become mindless,” Kara whispered, her voice a low husk as she licked her lips while watching Lena. “Keep your spray close just in case, and the condoms, and — and make sure that I take a suppressor tonight, okay? We can stop any time you want. I don’t want to push you into doing things just because you feel like it’s what an omega is supposed to do.”

“It’s not that, Kara. I want to keep you satisfied until your rut ends. I don’t view it as an obligation.” There was a touch of desperation in Lena’s voice as she approached the bed with a foil wrapped condom. 

 

Lena tore it open and rolled the thin sheath over Kara’s erection, only for the condom to snap and for the top ring of latex to pop off. She blinked in surprise and then automatically reached for a replacement, which she wrapped around Kara’s massive cock with careful fingers. 

Clearing her throat, Lena sat on the end of the bed and spread her legs open. She exposed herself to Kara and used the pads of her fingers to caress the shiny, pale pink of her inner lips.
 

Kara salivated at the sight and the scent of her omega, her glistening hole and the aroused red pearl that looked like a delectable sweet that she couldn’t wait to have in her mouth. The noise she made was barely human, a gruff sound of starvation that had her moving before she even asked for permission, crawling along the bed on her stomach to pry Lena’s legs further apart as she rubbed her face against the inside of her thighs reverently.
 

“Yes, yes I need this, I need you like this, please let me.” Kara’s whimpered pleas continued even as she ardently began to lap at Lena’s slicked folds. She moaned and shuddered as she licked languidly, her lips locking around Lena’s clit to lavish fully, only to release it with a wet pop so that she could tongue at Lena’s entrance.

Probing at the darker scarlet in desperation to taste Lena’s essence from the source, Kara sucked before drawing her labia into her mouth. She rolled her tongue over the soft, sensitive skin.  

In her enthusiasm, Kara pinned Lena to the bed with her legs spread wide apart, her appetite ramping up as she concentrated on flicking her tongue over Lena’s clit to feel the way her thighs trembled. The more the omega enjoyed herself the stronger her pheromones became.

 

Lena’s knees knocked inward around Kara and she gripped the bed sheets in loose fists as she moaned in a breathless series of whimpers. She seemed out of sorts, like she never imagined doing this with Kara before. Her pretty, shy blush ran from her face all the way down to her pale neck.

 

“So good,” Kara rambled deliriously, her rut fully beginning to affect her now that she was confined with Lena. “So good for letting me taste you, giving me what I need.”

Lena’s breasts moved as she rocked herself into Kara’s open mouth and she wove her fingers through wild blonde curls. 

Kara took firm hold of her soft curves and her hands roamed over Lena’s hips and ass and along her lower back. With her lips puckering around Lena’s sensitive bead of pleasure, Kara slid two fingers into her tight cunt. She pumped into Lena’s warmth and the omega writhed underneath her. 

“Yes, god, please keep doing that,” Lena urged and tried to move her hips outward to open up her stance for Kara. “Get me ready. I can’t wait to feel you inside of me. Make sure I can take all of you.”

Kara’s whole world faded from her mind, replaced entirely by Lena and all of her luscious fragrances. Every part of her called out to Kara and excited her senses, from the sounds of Lena’s breathy exhales, to the subtle musk of her sweat, and the heady richness of her arousal that tasted ever so slightly tangy on Kara’s tongue. The soft, slippery warmth of her inner muscles and the smooth, creamy expanse of her skin — Kara wanted to feel all of it, wanted to revel in it, to claim and hedonistically devour every inch of her omega.

 

Nothing gave her pause and Kara curled her fingers inside Lena’s soaked pussy and delighted in stroking the sensitive ridges that had Lena’s breaths coming in short, sharp pants. Kara sucked and licked at her swollen clit the same way she consumed a sticky dessert, and when she added a third finger to stretch her better, Kara shuddered at the sheer heat that enveloped her.

 

“This is right where I want to be,” Kara murmured thickly, barely audible because she was so focused on having Lena in her mouth. Her hips rocked into the bed, ruffling the duvet in her excitement, while her fingers thrust in tandem to open Lena’s tight canal with deep, diligent strokes that spilled slick onto her palm and chin.

Lena thrashed from the pleasure and raised her head up to watch her cunt accept three, then four of Kara’s fingers. 

“Wait, Kara, go slow,” Lena whimpered and her breathing changed until she was panting so hard that her chest heaved. Her pussy tensed but then relaxed around the intrusion of Kara’s fingers. When all of her juicy arousal drenched Kara’s palm, they both shifted in the bed.
 

Kara guided the omega onto her stomach with her ass raised and her knees parted. She crouched low above her and positioned her cock at Lena’s dripping entrance.

In spite of how excited Lena was, she still hissed softly when Kara’s erection pushed into her, too large for the narrow slot it was going to fill. 

Lena reached for Kara’s cock, keeping ahold of it with her hand as she tried to slide more into her pussy. The surrender of Lena’s inner muscles felt so good for Kara. 

Kara groaned under her breath, her fists pressing into the bed on either side of Lena’s ribs to hold herself up. Her arm muscles strained, defined veins popped to the surface and she gradually forced her hips forward with slow, but insistent pressure. She had to be careful, and she tried to remind herself of that by replaying Lena’s words over and over in her mind like a mantra. Kara, go slow. Kara, go slow. Kara...

The trouble was that she barely had half of her cock buried in Lena’s scorching hot depths and Kara could feel the way she stretched to accommodate her absurd thickness. She didn’t want to hurt Lena, but the incredible sensation of her snug slick walls combined with her rut had Kara’s willpower ebbing. The temptation to slam herself deep was so strong that an undignified sob broke out of her chest and she pressed her teeth into Lena’s shoulder with a pained snarl. Not exactly biting, but so close to it that she felt Lena shudder beneath her at the wild urges she displayed.

If she couldn’t plunge herself the way she desperately wanted into Lena’s exquisite depths, Kara rationalized that she should do the next best thing and pulled almost all the way out. She growled low in her throat, her teeth tightening around the flesh in her mouth to keep Lena pinned beneath her as she began fast, but shallow thrusts that pushed the broad head of her cock a few scant inches inside her dripping slit.

Their animalistic instincts took over and with long minutes of more powerful thrust, Lena’s slippery pussy took Kara’s girth. Kara got a glimpse of Lena’s deeper red canal every time she pulled back, so fully rutted open. It became such an addictive sight that Kara moved just to see Lena’s narrow hole in a complete spread.

“Can I tell you a secret, Kara?” Lena asked breathlessly and then shared her thoughts without waiting for Kara’s answer. “This is all I think about in my Omega Studies class. I don’t need to study mating. I just want to practice and learn by doing.”

Kara thrust harder with the determination to give Lena good practice, to train her tight cunt to accept the solid alpha knot that would be inside of her.

All of her alpha instincts came from a very dominant part of herself that Kara hadn’t realized lurked inside her. It was primal in its purest form, born of selfishness and unfiltered desire. Kara found herself pressing on Lena’s lower back to force her further into the bed while her ass was kept up to take every powerful plunge of her cock. The lewd smacking of their bodies was almost as addictive as feeling Lena’s pussy stretched to its limits just for her. It could be dangerous, the thrilling pull of knowing that Lena was giving her everything and would endure anything just to please her alpha.

 

It reinforced the idea that Kara should take what she needed, and she slid her sweat-slicked body over Lena’s to press her harder into the duvet, her hot mouth latching onto Lena’s neck just above the necklace to suck roughly. The sharp pain of it had Lena whining out, but Kara could feel the spasms of want in her cunt, the flood of arousal that coated her cock and dripped down Lena’s pussy lips at the demanding way Kara staked her claim.

 

If not for that, and how much Lena was begging and whimpering for more, Kara might have worried that she had gone too far in allowing her rut hormones to influence her.

 

She felt strong and wild from all of the sensations and scents of Lena as she slammed herself as deep as she could get with every thrust. It rocked Lena forward, and Kara grabbed for her hands to hold them above her head as she took her faster.

 

Kara interlocked her fingers through Lena’s, her soft growls turning to raspy moans as she husked breathlessly into her ear, “Do you want it? Do you want my knot, Lena?”
 

It was reaching the point of no return. Kara had never experienced a knot before, but there was an intense, almost burning pressure beginning at the base of her cock and she wanted more than anything to drive it inside Lena until they were joined completely.

 

Lena nodded as much as she could with Kara’s teeth still grazing over her neck in the spot she had bitten. 

“Yes, yes, Kara, I want it, I need it,” Lena moaned and chanted it over and over again as Kara buried her cock into her spasming, silken muscles. Her cunt clamped around Kara in hot, uncontrollable flutters. The scents of sex hung around them, and as Kara erupted in the condom, Lena’s pussy coaxed all of her thick seed out of her. It was an unending jet of pleasure, which lasted even as her knot bulged and connected them together. The tremendous bulk of the knot expanded Lena’s wet opening, and Kara shivered from the ecstasy of having it encased in the omega’s heat.

Lena grunted softly as they shifted, not wanting to disrupt the knot as they both moved onto their sides and into a more comfortable position. Kara slipped her arms around Lena and played with her clit to soothe any ache in her very full pussy. 

Kara never expected knotting to be so satisfying, but she had never known a relief like this, and she kissed all over Lena’s neck and shoulders in gratitude. She sucked at the tender mark on Lena’s neck, which was already a dark purple and shaped like the complete set of Kara’s molars. That possessive ferocity inside of Kara had yet to lighten up, and she pushed her other hand into Lena’s hair down to the roots, keeping her face close while she rubbed her. 

“It’s a good thing I’m ahead in all of my classes, because I have a feeling that we won’t be leaving your room much this week,” Lena husked and stared down between her legs, as if stunned to see how her pussy concealed such a huge knot. 

Kara hummed in agreement but she was preoccupied with touching Lena. Her fingers strummed over her clit faster, and she licked the bruise she had given Lena as she played with her swollen bead. It was clear that Kara was intent on exhausting her, and she groaned as Lena’s liquid heat clenched around her knot tighter.
 

Lena’s legs began to tremble, her breaths shaky and uneven as she shuddered and pressed back into Kara, unable to stop the way her body jolted and strained as the alpha brought her to another pulsing release that had her poor cunt clamping around Kara’s impossibly thick knot.
 

Kara unabashedly groaned as her cock throbbed inside Lena, spilling more of her come into the latex.
 

“We’re going to need more condoms.” Kara rumbled thickly, her voice hoarse as she nuzzled into Lena’s jaw, her fingers still gliding between Lena’s glistening lips to keep her stimulated.
 

With a soft whimper of desire, Lena rocked into Kara’s hand as best she could with the knot locking her in place and whispered, “Or we could just go to the pharmacy and get the extra strength pill only available to omegas.”

 

Kara went rigid, her breath sticking in her lungs as she thought about knotting inside of Lena without a condom. The idea of filling her pussy with obscene amounts of come had her cock twitching in anticipation. If she had been thinking clearly she would have said no, but in full swing of her rut, all Kara could rasp out was, “Let’s stock up on that.”
