Lena Luthor had always prided herself on her work ethic, intelligence and exceptional good wit — but the day that she noticed Dr. Danvers’ eyes on her ass while bending over a microscope, she began to take much more pride in what she wore to their private lab sessions.   

For years, Lena pined after Dr. Danvers and sat in the front row of her every lecture, answering questions before she even posed them. Lena wanted to impress everyone with her knowledge of different planetary systems and their respective laws of physics.   

At first, it had mainly been about proving her right to take advanced courses when she was younger than the other students, but after her fourth Graduate module with Dr. Danvers some years later, she realized that her focus had drifted. She was spending more time focused on her Dr. Danvers’ body than on the celestial bodies she should have been studying. 

Not that it affected her grades, because Lena had already read all of the course materials twice at that point, but she was worried enough about the distraction, because it made her suddenly too shy to participate. 

Dr. Danvers had called her up after class, and Lena kept her eyes on the floor in embarrassment after spending a few moments staring at Dr. Danvers’ solid arm muscles.   

Seeing Dr. Danvers in a sleeveless shirt always did dampen Lena’s panties and cause her to fidget. She played with a pen cap while she waited for Dr. Danvers to address her, but rather than complain about Lena’s lack of participation, her professor had only asked, “Are you okay?”  

With a tiny smile of reassurance, Dr. Danvers had sat on the edge of the light oak desk behind her. 

“I’ve noticed you’ve been distracted lately and I just wanted to make sure that no one is bothering you,” Dr. Danvers had explained with gentleness in her pretty blue eyes. 

In the past, some of Lena’s male classmates had been less than welcoming of her and did all they could to discredit her, though she was intellectually their superior. She had turned in a formula to the physics department that was worthy of a Ph.D., and after that no one questioned her or wasted their time trying to make her feel small. 

“I’m fine,” Lena had muttered, and although she peeked up at Dr. Danvers, she immediately directed her gaze back to the floor. “I’ve just been – bored.” 

Bored? 

That was the last adjective she had been reaching for, and yet in the end, it was that little mistake that had gotten her the opportunity to work closely alongside Dr. Danvers on a special research project.   

Dr. Danvers had offered her a challenge straight away.   

Two years had gone by since then, and Lena had earned two advanced degrees while working as Dr. Danvers’ research assistant. 

Her work involved modeling the cores of planets across several different solar systems to compare them to Krypton. Using Python and Matlab, Lena tested models and calculated how each planet would respond to the conditions that led up to Krypton’s explosion.   

To make her calculations as accurate as possible, she needed to study the biosphere and plant life of each planet. She sent away for samples and spent whole afternoons creating wet slides from them. 

It might have been a dull job for someone else, but Lena liked the professional atmosphere of the lab and wearing heels and a short skirt every day.     

While she was investigating how each planet reacted to rising radiation levels, or certain chemicals in the atmosphere, Lena also began studying how Dr. Danvers reacted to her. 

If she wore a skirt that tapered far above the knee, and light fishnet stockings with a pair of four inch pumps, Dr. Danvers would get flustered and retreat to the opposite side of the lab.

There appeared to be a direct correlation between the way she sucked on the end of her pen while lost in thought, and how many times Dr. Danvers excused herself from the room to grab a coffee.  

Lena privately noted that on several occasions, Dr. Danvers returned minutes later without any coffee at all, but there would be a glow about her cheeks and redness to her lips that Lena found enticing.   

Neither of them mentioned it, and Lena began to conduct some secret experiments. 

What she concluded was that Dr. Danvers stole glances at her throughout the day, almost as many as Lena herself stole at her in return.  

Whenever Lena made a new discovery, or wanted a second opinion on one of the slides she was examining, Dr. Danvers would lean over her shoulder with her hand lightly on Lena’s lower back, and subtly inhale the sweet scents of Lena’s perfume. She lingered the longest whenever Lena had spritzed herself with Pure DKNY that morning. The soft, fresh scent of vanilla and roses must have appealed to Dr. Danvers and Lena wanted to discover what else the gentle-spoken professor liked.  

Made bolder by the idea that the attraction was mutual, Lena decided to take a risk and started to show up with the top two buttons of her shirt undone.   

When Dr. Danvers caught sight of the parted fabric, it sent a bolt of arousal through Lena so strong that her panties were basically ruined.   

She felt perpetually wet every day they worked in the lab together from that moment on. By coincidence, that was also the day Dr. Danvers asked her to start calling her Kara. 

“You’ve known me for a long time, and it would be okay to drop the formalities,” Kara explained while she reviewed Lena’s most recent set of calculations. 

In spite of this minor change, there was still a firm boundary in their student-teacher relationship until several weeks later when Lena’s ride failed to show up. Her friend Eve had blown her off to go to some party, and Lena was about to arrange for a Lyft when Dr. Danvers drove up in a classic muscle car. 

Rolling the window down, Dr. Danvers met her eyes with concern and asked, “Hey, Lena, do you need a ride home? Why don’t I take you?” She suggested it easily with a slight crease of worry between her eyebrows as she added, “I don’t want to leave you standing out here in the dark alone, but if you’d rather call a cab, I can wait with you until it arrives.”  

What was a girl to do when offered such an invitation?   

Lena felt her heart flutter, and her feet made the decision before her brain could persuade her out of it. She was already walking around the car to get into the passenger seat before she consciously realized it.   

“Thank you, Kara. I guess my friend had better things to do tonight,” Lena mumbled shyly, inhaling the soft leather scent of the seats and the pine air freshener.  

Once Lena was buckled in, Kara pulled off with a sigh, “Well that’s not very responsible of them, but at least it gives me the chance to say how impressed I am with all of your research. You’re a brilliant and talented young woman, Lena, and I would never have been able to get that recent grant without you.”  

Kara’s bright smile disarmed Lena, and she found herself grinning back as she gushed, “Oh please, you’re basically a legend. You inspire hundreds of people every day. I can only hope to accomplish half of what you have.”

Either it was the shadows in the car, or Lena had caused a blush to spread over Kara’s face. She found it endearing and stared perhaps longer than she should have, because when they came to a stop light, Kara turned to her, and for a second a palpable heat radiated between them. She swallowed and turned away with a laugh that caught in her throat.  

“So where is it I’m taking you?” Kara asked. Her hands were tight around the wheel but her smile was soft and relaxed as she glanced at Lena.  

“You can just drop me off in town,” Lena stated impulsively. Her palms were sweaty and she was far too focused on Kara’s hands. She wondered what they would feel like gripping her thighs like that, and bit her lip to try and shake the thought of it. “I don’t want you going out of your way just for me. I’m sure you’re busy.”  

Kara chuckled as if Lena had told a joke and tipped her head to the side to confess, “Lena, the only plans I have for tonight is to pick up Chinese food on my way home, so don’t worry, I’m not going to be late for anything. I can eat pot stickers and lo mein later.”  

Lena wasn’t sure what compelled her to say, “That sounds so much better than leftover pizza,” yet the words flew out of her mouth all the same. She dryly explained, “I share an apartment with friends and cooking isn’t exactly our forte.”  

Kara fell silent for a brief moment, her teeth embedding in her lower lip before she asked, “Well why don’t you join me and I can drop you off afterwards?”

It was almost pathetic how fast Lena accepted the offer, and how once inside the professor’s apartment, all she could think about was how much she wished Kara would give her a different kind of education. She sat down on the sofa, opened the buttons on her royal blue coat and crossed her legs, only to play with the hem of her dress while Kara ordered their food. 

Kara’s buff arms distracted Lena, along with the hard abs she could see through the thin knit grey sweater she wore under a tweed jacket. With eyes bluer than water and her blonde hair knotted in a tight ponytail, Kara was attractive by anyone’s standards. 

Lena casually glanced around the apartment for any signs that Kara lived with someone. 

Kara never mentioned a significant other, so Lena decided to bring it up in casual conversation.  

“Will your partner be home soon?” Lena asked and blinked as she peered around the apartment, noticing a laundry basket in the corner with familiar slacks and tops.   

“I’m actually — I’m single,” Kara stammered out and flailed awkwardly as she sank onto the couch beside Lena. Her lips ticked into a tiny smile that grew in her eyes when Lena’s grin broadened.   

“You must be too busy for a relationship, given the number of articles you’ve published this year alone, and all of the conferences you’ve attended,” Lena pointed out, and then rubbed her thighs together inconspicuously, if only to lessen the palpating ache between them.   

Being aroused in Kara’s presence was a frequent problem for Lena, but it was also just as frequent a problem for Kara.    

Along Kara’s right thigh, Lena noticed a soft bulge that she expected would harden the longer they sat together.   

“I am very focused on my work.” Kara agreed through a laugh, the slant of her lips a little self-deprecating as she shifted to sling an arm over the back of the couch to face Lena more fully. Her eyes widened as if she had been struck with a thought out of nowhere, and she swept her hand through the air. “I’m being a terrible host.” She declared dramatically. “I forgot to ask if you wanted something to drink. I have coffee and tea, or uh—soda?”  

Lena was about to say water when an idea came to mind, and she smiled sweetly and finally tore her eyes off of Kara’s pants. “I’d like a soda, thank you.” She waited until Kara had gotten to her feet before innocently asking, “Do you have any straws?”  

Kara tipped her head to the side and squinted as she considered it. “Um, I think I might have one lying around, let me see what I can do.”

Lena watched as Kara poured two glasses of coke and then rummaged through her cabinets for a straw. She eventually found one in a drawer, and the way her face lit up made Lena grin.  

Dr. Danvers had one of the most brilliant minds she ever had the pleasure of working with and she was an absolute dork.   

A hot dork. Lena’s mind corrected as Kara strutted over to proudly give her the soda, complete with a straw.

“Thank you, Starbucks.” Lena teased as she accepted the still-wrapped straw from the major coffee chain.  

Kara laughed and sat back down to sip her own soda. 

Kara’s knee brushed against Lena’s and a pleasant little jolt when through her—a touch of electricity that had Lena tingling for more.

Lena waited until Kara’s eyes were back on her and then used her tongue to pull the plastic straw into her mouth. She wrapped her lips around it and hummed as she took a sip, and Kara shifted slightly and cleared her throat.

“So you uh—what about you Lena, are you seeing anyone special? I imagine you must go on a lot of dates.” Kara muttered distractedly, her eyes lingering on Lena’s mouth.

“No, but there is someone I’m interested in.” Lena admitted and deliberately toyed with the tip of the straw as if she was doing it absentmindedly and not entirely in a calculated way. “You know, you’ve been drinking a lot of coffee lately. I’m surprised you didn’t make one.”

Kara looked a little baffled and her cheeks turned pinker. She blinked a few times and met Lena’s eyes with a confused smile, “I’m sorry?”   

“At the lab, you grab a cup at least two or three times a day.” Lena intoned and sipped her drink, if only to give herself a reason to peer down at Kara’s lap. The fabric looked a little tighter and she quirked a dark eyebrow at the way the bulge had gotten bigger.   

“Oh well— I — I hadn’t noticed that it was so frequent.” Kara said awkwardly and took a gulp of her soda. “I guess I run on caffeine.” She joked, though her smile was tense and her laugh sounded strained to Lena’s ears.

Lena continued to suck on the straw and swallow while Kara watched intently. “I try to avoid coffee most of the time, ever since I attended that lecture that Jack Spheer gave on the correlation between caffeine and a lower sex drive.” 

She knew mentioning sex might risk their entire delicate dynamic, but she spoke like a scientist describing the facts of biology rather than a young woman who was desperate to explore her sexuality. 

 In the past, Lena had a few awkward fumblings with inexperienced people and none of them were worth repeating. Somehow she sensed it would be much better with Kara. Lena kept glancing downward at the rigid, massive cock hidden in Kara’s pants and tried to remember when she first noticed it. 

 It must have been during one of their early lab sessions, when Kara stood too close to her and Lena felt the erection even through her lab coat. By accident, and because they worked in such close quarters, Lena had become well acquainted with the shape and size of Kara’s cock and how it hung more than halfway to her knee when hard. The massiveness of it intimidated Lena at first, but sometimes in the privacy of a bath or her bed, she would try to imagine Kara pushing into her, despite never having felt that kind of stimulation before.    

All of her dirty fantasies involved Kara’s cock. Kara’s cock would open and fill her cunt, and after she took it in good and deep, Kara would pound into her for hours. Her mouth went dry from hanging open while she dwelled on the idea of it. 

The Chinese food deliveryman knocked at the door, saving Lena from herself, and Kara lurched up to pay him. It seemed like Kara handed over more cash than necessary and then she almost dropped the noodles in her rush. 

Kara thrust a pair of chopsticks into Lena’s hands and began dumping full cartons of food onto plates. 

“What other recent lectures have you attended?” Kara asked conversationally, but from the rapid way her mouth formed words, Lena could tell there was an underlying anxiousness that gripped the professor. “Anything interesting? I know some can be incredibly tedious, depending on the topics, but others can be mind-blowing.”

Lena was certainly thinking of blowing something but she kept that to herself as she watched the way Kara piled an incredible amount of food onto her plate. “I’ve gone to a few on Quantum chromodynamics, but the lecture that sticks in my mind the most was one by Maxwell Lord.”

Kara’s eyebrows furrowed as if she was personally offended by Lena’s choice, and in her haste to sit up she almost toppled her plate over. “Really, that’s uh—why?” She questioned, and settled the plate in her lap. “I mean he’s—” Kara squinted slightly, as if trying to find something nice to say about him and settled on, “Well I suppose some people might find him interesting.”

Oh, Lena shouldn’t have felt so pleased with herself at the hint of jealousy in Kara’s tone, but her grin was positively wicked as she nodded along. “He is, isn’t he? He spent a good deal of time discussing the connection between imaginative play, and sexual desires where it applies to engineering. His new train design certainly backs up his theory.”

There was no way to disguise the appalled way Kara’s jaw dropped and she floundered for a good few seconds as she tried to appear neutral. “Why would anyone even…” She trailed off only to back track. “With a mind like yours Lena, I dare say you’re well beyond anything Maxwell Lord could ever hope to understand, but if you... enjoyed... what he had to say-- ”

Rich, dirty laughter bubbled up inside Lena and she leaned over to touch Kara’s forearm as she admitted, “I’m joking, Maxwell never held a talk, and even if he did, I’d never attend it. I just wanted to mess with you a little.”  

Lena took her hand back and twirled a chopstick between her fingers before she scooped up a dumpling from Kara’s plate and popped the entire thing into her mouth with a triumphant smirk. She chewed and swallowed before flirtatiously licking her lower lip and elaborating, “You’re always so focused on work. You should take a night off. You know, loosen up, talk about something fun.”   

Kara frowned in perplexed silence and blushed a beautiful bright pink before she shook her head. “I spend so much time at work I think I’ve forgotten what fun even is.”

“Okay so that’s a lie,” Lena lilted and leveled Kara with an amused chuckle. “You practically dance whenever we’re making new discoveries, but,” She held her hand up as if to pause the conversation and reached for her bag, “since you mentioned how you have no life—”  

“Well now you’re just being rude.” Kara teased in return, and added with a slight grin, “I have a life, it just mostly revolves around working and sometimes sleep.”   

There was a guarded look in Kara’s blue eyes that softened when their gazes locked. It made Lena think of melting ice and she reached into her bag to pull out a flyer she had taken from a bulletin board on campus. It advertised a cooking class for couples and she clutched it tightly, crinkling the shiny paper.   

“Hey I’m not judging, I don’t exactly have a life outside of the lab either,” Lena laughed. “Not many people want to get to know the new prodigy, especially when she’s younger and smarter than they are.” She muttered, her smile faltering as she tried to ignore the seriousness of how lonely it could be.

Flickers of recognition and understanding passed over Kara’s face and she reached over to place a comforting hand on Lena’s knee. “I know you’ve probably heard this before, but take it from an alien that landed here as a pre-teen: it does get easier, Lena,” Kara gently assured her. “And anyone who isn’t smart enough to see how great you are doesn’t deserve to be your friend anyway.”

A wonderful tingle shot up Lena’s leg at the contact and she thrust the flyer into Kara’s hands before Kara saw how breathless she had gotten. She pressed on with what she had been planning to ask Kara. 

  “You know, I’m great at chemistry, but somehow I’m a disaster in the kitchen.” Lena confessed and pointed at the flyer, which detailed all of the different gourmet meals that the instructor of a cooking course would teach the participants to make. “I already signed up for three of these lessons, and I planned to drag my friend Eve along with me, but why don’t you join me? Since we’re both loners who have nothing better to do.”

Kara snorted under her breath, and made a face as she peered down at the flyer. Her lips pulled tight and she pushed her glasses up the bridge of her nose as if debating what to say. “Wouldn’t your friend be upset if you gave her spot to someone else?” She finally asked, and avoided Lena’s eyes as she waited for an answer.

“You mean the one who decided to go to a party instead of picking me up?” Lena countered sarcastically and quirked a dark eyebrow. “I can’t say she would.”  

“Well when you put it like that.” Kara smiled with a hint of uncertainty in her tone. “Full disclosure, the last time I tried to cook anything I almost set the kitchen on fire, which I guess is a good enough reason to learn from a professional.” Kara sighed dramatically, but she grinned at Lena and stood up to affix the flyer to her fridge with a magnet. “Don’t be surprised if my sister calls you to thank you personally.”

Lena never heard from Kara’s sister – but the following Tuesday, she got the privilege of seeing Kara not only panic as she tried to beat eggs and incorporate flour into a mix, but she also got to see up close and personal just how clumsy the usually-methodical genius was when faced with a complicated recipe. 

Kara moved around like a small natural disaster in the kitchen, and it was endearing to see the way she tried so hard to keep up with everyone else.    

“Breathe,” Lena encouraged, and subtly leaned into Kara so that she could whisper, “We study planets for a living. Together I’m sure we can make a cake.”

They couldn’t.   

When the cake came out of the oven, it was simultaneously over cooked around the edges and raw in the middle. The Chef was amused, but told them not to give up. 

Kara arrived at the lab the next day with a slice of chocolate cake just for Lena to apologize for ruining the one the night before.

 Lena perched on her stool to eat it and raked her fork through the icing while she watched Kara with a glimmer of desire and appreciation in her eyes.

After Lena finished devouring the cake, she wrote a thank you note on Kara’s whiteboard and then started adding her most recent findings to her data map of planetary systems. 

Around the middle of the afternoon, Kara tugged up a seat beside her to review Lena’s most recent work. 

“I’ve identified a planet with a biosphere similar to the one on Krypton. I’ve been running a lot of simulations to determine how that planet might respond under different sets of conditions,” Lena explained and brought up her data set, which included environmental factors, gases in the atmosphere, and tectonic plate activity. “If I had to form a theory at this point, I would say that Krypton experienced a slow heating over time, so slow that plants and animals were able to adapt to the new conditions—but the rise in temperatures made the planet less hospitable to life.”    

Lena clicked through a few slides to show her comparisons based on the planet Xolnar, which seemed to also be experiencing a slow-heating. 

“I think it’s likely that while the Kryptonians were depleting the planet of natural resources like oils and minerals, they were also pumping other chemicals back into the soil,” Lena stated. “I don’t have any hard evidence of course, but there’s a certain kind of metal on a neighboring planet called Peluna. If the Pelunians were also using Krypton to off-load this toxic metal, and the Kryptonians decided to dispose of it the wrong way, it could have caused a large-scale explosion.”    

“That’s a brilliant theory, Lena,” Kara whispered in awe and scrolled through Lena’s calculations and input data. “Mind if I borrow this for a little while?” She carried Lena’s tablet around, occasionally pulling at the frame on her glasses as she worked through problems in her head. An epiphany must have struck her, because she rushed off to her computer. 

In a database about Krypton, Kara located a file about Pelunian metals. 

  “This has to be it,” Kara muttered to herself and her whole face radiated pure excitement with her findings. “Lena, I think there’s enough evidence here to substantiate your theory!” 

Lena scooted up from her seat and hurried over to Kara to squint at the documents on her computer screen. As a smile of triumph dimpled Lena’s cheek, Kara drew her into a congratulatory hug and spun her around in excitement.

 “Thank you, thank you,” Kara chanted hotly against her ear, overjoyed by the development in their research. “You’re amazing,” She praised and her lips pressed a chaste kiss to Lena’s cheek.

Lena froze in surprise, but then she tightened her arms around Kara’s back and melted into the embrace. “So are you,” She stupidly said, blushing profusely as Kara released her to quickly type something up.   

“We should celebrate,” Kara declared, her grin radiating delight as she turned towards Lena. “My treat. Dinner anywhere you want.” She insisted, pulling off her lab coat to hang it on a rack by the door. 

The sight of her bare forearms caused Lena’s mind to fog up with lustful thoughts and her gaze wandered to the front of Kara’s pants. She thought about Kara’s hands, and how they might feel if they were in her hair, holding her while she was on her knees.

She snapped out of it when Kara held her jacket out for her and rumbled, “I know what you’re thinking.”   

There was a mischievous slant to Kara’s lips and a knowing glint in her gaze.  

Lena’s eyes nearly popped out of her head and she inhaled so sharply she almost swallowed her tongue. “You can — wait, you can read minds?”

“No.” Kara grinned and playfully clapped her on the shoulder. “I just meant that I know you probably don’t think that having a meal is much of a celebration.”

For someone so eloquent, Lena felt tongue-tied and flustered as she tugged on her jacket. She wondered if she could, legally, shoot herself into space to avoid further embarrassment.

“So, where would you like to go?” Kara asked, ushering Lena out of the lab and through the hall that led to the east parking lot. 

“There’s that new Asian fusion place downtown,” Lena suggested, for lack of a better option and because Kara had such a fondness for Asian cuisine. “I hear they have giant soup dumplings on their menu.”

 “Two great discoveries in one day,” Kara marveled and threw her hands up as if tickled by her excellent luck. She chivalrously opened Lena’s door for her and then dashed around to the driver’s seat. 

 Lena leaned over to get the door for Kara in return and then buckled her seat belt. While Kara fussed with the radio, she rolled down her window and propped her arm up on the leather. She planned to stare out at the landscape and avoid gawking at Kara at all costs, but her traitorous eyes continued to roam. 

 Wetting her bottom lip, she followed the hard curve of Kara’s bicep down to her hand where it rested on the wheel. She glanced back at Kara’s mellow face and then honed in on the soft bulge in her slacks. 

 “Do you ever wish you had a someone special in your life when celebrating these big moments?” Lena asked at random, and pulled open her bag as an excuse to search for her sunglasses. She wanted to put them on her face to prevent Kara from seeing where her gaze restlessly wandered, but she never opened the case.    

Kara’s thumbs lifted off the wheel as she tipped her head to the side, “Usually I tell myself it doesn’t really matter, but between you and me?” She glanced at Lena, then turned her attention back to the road with a sigh. “Nothing emphasizes how alone you are quite like success.” She forced out a laugh and hastily added, “Sorry, I didn’t mean that to sound so cynical. Besides, I’m not alone. We’re sharing this victory.”  

Lena’s smile was filled with adoration and understanding, because she knew how Kara felt. “No I get it. Having family and friends isn’t the same as having someone you connect with on a deeper level. Someone who gets you, and sees you for who you are, not just what you are.” She whispered, her teeth catching her lower lip in intrigue as she stared at Kara. 

“Yes, you’re exactly right. When you find it with someone, you’ll know.” Kara’s smile faltered as she pointedly kept her gaze on the road. Her hands were tight around the wheel again, and her tone was serious as she muttered, “It's a special thing, a connection like that.”  

“Yeah, it is,” Lena readily agreed, and maybe she had lost her mind, because her heartbeat was in her throat and her hand was moving of its own accord to rest on Kara’s thigh. The contact sent a rush through Lena and she inhaled deeply.  

Kara’s thigh jumped beneath Lena’s warm palm and they both stilled, perhaps in shock over the heat that sizzled between them and thickened the air. Kara seemed to be struggling to breathe and Lena’s tentative fingers quested further to skim the fabric around the outline of the bulge. Her fingers ghosted along the crease and Lena watched as Kara’s cock began to grow in response.  

“Lena, you’re my student.”   

It was the first time Kara had ever said her name in warning, and her tone was almost as firm as the erection she sported. She was staring ahead, her jaw tense, as if she couldn’t trust herself to look at the hand on her thigh.   

Lena dared to run her fingers over the tented material, her palm brushing across the fabric to grasp the thick length. It was so big that she doubted her fingers could wrap around it, and she exhaled a low moan of want. Her panties would be absolutely ruined just from the excitement that flooded through her.

“Then teach me,” Lena whispered, her fingers teasing over the rigid length as Kara drew in a sharp breath.  

Kara hit the indicator and turned the car out of the inner lane. Her body seemed to be fighting the words that poured out of her mouth, because her hips pushed upward even as she blurted, “Do you have any idea how inappropriate that would be? You’re—”   

“Legally old enough to date you.” Lena supplied easily. She wasn’t sure where her confidence was coming from, but she knew what she wanted and had known for long enough to be certain it wasn’t just a fleeting crush or a silly fantasy. She had feelings for Kara and she couldn’t contain them any longer, because she was certain that Kara felt the same way.  

“That’s — that’s not the point, Miss Luthor.” Kara’s voice cracked and she swallowed as she glanced around for oncoming cars. She steered down a long stretch of private road and away from the town where they should have been heading. “I’m an alien, and you? You’ve got a bright and promising future ahead of you.”   

“Those things aren’t mutually exclusive.” Lena smartly remarked and quirked a dark eyebrow as she palmed the hard length as if to make a statement of her own. “You like me just as much as I like you, so why should we deny ourselves this?”  

Kara pulled the car to a stop somewhere near a field, yet she still couldn’t turn towards Lena, as if looking at her would unravel all of her resolve. Her hands were still clutching the wheel and her chest was heaving. “Having feelings doesn’t mean we should act on them.” She stressed with a conflicted expression on her face as she stared out at the darkness.   

“But maybe we should and see what happens,” Lena suggested, and then tightened her finger and thumb on Kara’s zipper to tug it open just enough to stroke her cock through her boxers.     

Her expectation had been to free Kara’s erection, but the head was too broad to poke through the space in the pants. Bending across the seats, Lena popped the button above the zipper and located the partition in Kara’s boxers. Slipping her delicate hand through it, her fingers found the huge tip of Kara’s cock and she guided it out. The ridge along the tip was imposing, with a groove that already drizzled arousal. 

 As Lena held it against her own forearm, she saw that Kara’s cock was much wider in thickness. Flutters of need went through her and a thrilling sensation in her belly made her feel like she was dropping. She finished pulling Kara’s length out of her confining pants and gaped at its size. 

When rigid and upright, Kara’s cock extended almost to where her hand was still secure on the steering wheel. Lena’s breath hitched and she lowered her mouth towards the enormous head. 

Kara’s hand pressed at her shoulder, but all she muttered was, “Lena, oh—oh Rao,” and then her fingers wove into Lena’s hair.

Lena smudged her matte red lipstick as she forced Kara’s cock deep into her throat. Her lips had to stretch and her jaw ached horribly but she wanted it in her mouth. The natural urge to choke did nothing to stop her and she swallowed hard around it, even as tiny spasms of resistance went through her and the tendons in her neck strained. 

 She went at it eagerly, and for a while the wet plunging sounds of her mouth on Kara’s cock was the only communication shared between them. 

 Lena took more shallow strokes of it, pushing the first few inches of Kara’s cock into her soft cheek. She concentrated on the thick head, curling the tip of her tongue to lick the drips of desire away. Her lips darkened from pumping at such an enormous cock, and she finally cough-choked when she became ambitious enough to take more and only ended up prodding herself in the tonsils with it.   

Breathing harshly through her nostrils, Lena sucked with hollow cheeks until her chin was a mess of Kara’s desire and her saliva. “Please, Kara,” She husked when she paused to give Kara’s cock a firm tug with her hand. “Please, I want you to come in my mouth. I’m not ashamed to tell you I’ve thought about it before.”

There was a way that some people described girls like her. The phrase came into Lena’s mind as she accepted more of Kara’s cock into her throat: Kara made her cock-hungry to the point that she refused to even take a breath.

From her soft, throaty groans, it was clear that Kara couldn’t form any coherent words, but her fingers tightened in Lena’s hair as if to signal she heard her. Lena doubted anyone had treated Kara this way before, and it fueled her on, desperate to show that she wanted Kara so completely, so greedily, that she would learn to take it all if given the chance.  

Lena flattened her tongue along the sensitive underside of Kara’s cock and opened her mouth as wide as possible. Then she brought her own hand up to clasp over Kara’s to encourage her to control how much she took.  

Kara must have been lost in the pleasure of it all, because she began to guide Lena’s head, the tip of her cock pushing into the back of her soft throat a few times before she held her there for a moment, and Lena could have come from the way Kara husked under her breath, “So good, Lena.”

The sloppy noises and breathless rush of it all had Lena moaning, but it was seeing the way Kara was watching her, jaw slack in surprise and with soft, lustful eyes, that made her go faster. The back of her throat would hurt all night and her face would ache for days, but god it was worth it as she rammed Kara’s cock down her throat.   

Lena had wanted this for so long, and if this was her only chance to have it, then she was going to make sure it was phenomenal for them both. With watery eyes and red cheeks, she swallowed around the head of Kara’s cock and fluidly moved her hand over the rest of her shaft, begging with her eyes for Kara to give a taste of what she craved. She moaned without shame and then Kara’s thick shaft went rigid in her mouth. Lena sealed her lips tightly as Kara’s guttural groan was punctuated by the first throbbing pulse of her cock.

Kara shot a generous load of seed into Lena’s throat, and her nostrils flared as she swallowed it all down. With gulps that made the small dip in her neck quiver, Lena savored it to the final drop. She wiped the last trickles from her face and licked her bottom lip. 

As she shifted upright and returned to her seat, Lena whispered, “So was that the third discovery of the day?” 

Kara hastily shoved her cock back into her pants and zipped herself up without answering Lena. She stepped out of the car to breathe in fresh air and leaned against her driver’s side door.   

Lena gave her the space to process what had happened before joining her. 

“Kara, I know that what we just did was risky,” Lena began in a soft and entreating voice, “but I promise you, if it comes to it, I’ll just resign from my position as your assistant and I’ll find someone else to advise me on my research. I planned to ask you to act as my Ph.D. advisor, given the major overlaps in our interests—”

Kara laughed in a quiet, hysterical way and threw her head back to gaze up at the stars. “I don’t even think there’s anyone else qualified to supervise you, but after what we just did, it would be absolutely unethical. It’s already unethical—”

Lena put her hand out in consolation and that simple touch changed Kara’s frenetic energy. Kara hunched over with her arms against her chest. 

“I didn’t even—I didn’t even kiss you first,” Kara squeaked out in self-reproach and hung her head. “You just—with your mouth—and I… oh Rao.” 

Lifting one of Kara’s arms, Lena draped it around herself and stepped closer into the embrace of her own making. 

“I’m well beyond the age of consent, I’m no longer enrolled in any of your classes, and so what if you become my Ph.D. advisor?” Lena asked and canted her head to the side as she considered the shadows that fell on Kara’s face. “Not to brag, but I should have been awarded several doctorate degrees by now for all of my hard work.” 

 Kara let out an exasperated sigh and stared back at Lena with a perplexed scrunch of her brow. “You’ve really thought about this at length.” She noted, without any hint of surprise, yet she didn’t take her arm back as Lena nestled closer to rest her chin on her shoulder.   

Heavy silence fell over them, and it wasn’t until Lena began to shiver that Kara murmured, “We should get back in the car.” She waited for Lena to get in first before she slid behind the wheel again. Kara didn’t say where they were going when she turned the engine on and blasted the hot air, but she pulled back onto the main road.   

Lena caught sight of herself in the side mirror. Her hair was ruffled and messy from where Kara’s fingers had held it, and her lips were a dark, plum color. On the back of her tongue, she could still taste the faintest salty musk. She looked fresh faced and happy, a direct contrast to the gloomy, silent blonde driving. 

 “Please talk to me,” Lena whispered, her hand halfway to Kara’s thigh before she faltered and thought better of it. “I’m not a mind reader either, Kara. If I’ve caused a problem then I’d like the opportunity to fix it.”  

Kara swallowed and her teeth worried her lower lip as she glanced shamefully at Lena. “You didn’t cause a problem, I’m the problem,” she asserted. “What I feel for you is a problem. How much I enjoyed what just happened is the problem, Lena.” Kara’s voice had gotten a little shrill and she paused just to suck in a ragged breath before hurtling on hysterically. “I shouldn’t have allowed it and I did. Now I keep thinking about Krypton, and how it burst into flames, and how I landed here with this belief that I would have a purpose and do good. I dedicated my whole life to understanding what happened on my world for my own sanity, and out of respect for everyone that was left behind to burn. Then you showed up one day. Like stardust scattered across space, you just fell into my life—and later into my lab, and all the years went by so fast. Then I started to realize that I wasn’t waking up in the morning feeling as empty as I always had, because I’d be spending the day working with you. All of this should bother me, but the truth is what’s tearing me up the most right now is that I didn’t even kiss you first.”

 Maybe she dived in too fast, but Lena didn’t feel any regret when she heard that Kara had feelings for her. She felt bad that she caused such a flux in anxiety but when she placed her hand over Kara’s on the wheel and felt the tension slip away from Kara’s fingers to interlock with hers, she knew exactly how to make it better. 

“Take me to your apartment.” Lena requested softly.

Kara looked at her so fast that she could have crashed the car. “What? No, we can’t—”

“Not for that,” Lena hurried to clarify, her tone amused but eyes soft and brimming with emotion as she brought Kara’s hand onto her lap just to hold it sweetly in hers. “I want you to kiss me, Kara. Not somewhere that will feel wrong or rushed, but in the comfort of your home where we can take our time.”

“Oh.” Kara exhaled like that hadn’t occurred to her, and within twenty minutes, that’s exactly where they were. Sitting nervously on the couch with palpable sexual tension between them, until Lena took Kara’s hand and brought it up to her cheek and Kara surrendered to the magnetic pull of their emotions and brushed her thumb adoringly over Lena’s cheekbone.

They came together slowly, with soft breathy exhales and tentative whispering lips that seemed to gravitate closer like planets destined to collide. The first contact sent a delicious shiver down Lena’s spine, and she felt more than heard the noise that Kara made. Kara led the kiss. With a soft swipe of her tongue over Lena’s lower lip, she slipped her fingers into her dark hair to cradle the back of her head and deepened it to taste Lena’s mouth.

It was the first time Lena had gotten wet just from kissing, and over the next week she would get wet from the anticipation of going to Kara’s for dinner and make-out sessions.   

Kara had gradually became more accustomed to Lena admiring her erection, though she kept it in her pants since the night in the car, and Lena had confessed that she experienced pleasure from the mere thought of touching it. Apparently it was foreign notion to Kara, so Lena took it upon herself to show her the proof like any good scientist would.  

On Friday night when Kara had called up to order a pizza, Lena unbuckled Kara’s belt and freed her cock with a breathy sigh, as if she had been the one contained for days. She poured strawberry flavored lubricant into her hand and stroked Kara thoroughly to completion, covering her hand and her chin with creamy spurts of hot seed that had left Kara simultaneously aroused and unsettled.   

Lena relished how flustered Kara got when she saw her come covering her. That was when she slipped her panties off to show Kara how drenched they were with her own excitement and Kara’s cock instantly hardened again at the sight.

Kara noticed the bottle of lube on the coffee table and picked it up to squint at the label and ask, “What is this?”     

“I bought it because I want to use my mouth on you,” Lena intoned, but she left the lubricant aside because she needed the flavor of Kara.   

She bit her own lip to restrain a soft moan and moved onto her knees in front of Kara. Her plush mouth hovered above Kara’s cock, and with slow flutters of her tongue, she licked the divot at the top. Fresh beads of arousal formed and Lena lapped it up.     

Closing both hands around Kara’s girthy cock, Lena stroked and sucked at the same time. Kara rewarded the puckering of Lena’s mouth around the barest tip of her cock with another hot gush of desire. 

With all of the mess on her lips, it was much easier to push them down over Kara’s huge erection. She tried to go as far as she could, bobbing her head faster, and Kara’s cock popped wetly through her lips. 

 Kara’s fingers threaded into her dark hair and her thighs clenched with anticipation. “Do you have any idea how amazing this feels?” she groaned, pink in the face both from pleasure and embarrassment.   

“It’s my fault that you’re hard all of the time, so the least I can do is suck your cock,” Lena boldly told Kara, and opened wide to force several more inches of Kara’s hard dick into her mouth.

The natural moisture on her tongue made it easier for Kara to thrust into her, which Lena encouraged by gripping at her thighs. Watching every sensual desire on Kara’s face, Lena stared up at her with intense and focused eyes. 

 Kara reached out to caress her face while rocking into the warm confines of Lena’s throat, her hands unsteady as she pushed dark hair behind Lena’s ears and locked her fingers at the back of her head.

Lena moaned provocatively around the thick intrusion and whined as if she were trying to beg Kara to give her more.  

Kara took the hint, and pulled Lena’s face closer, gasping at both the sensation and sight of Lena gagging as more of her cock forced its way into her mouth. The tight, hot muscles of Lena’s throat constricted as she swallowed several times, and Kara groaned unabashedly, her hips rocking up to chase the pleasure of it, and Lena moaned louder.  

Saliva pooled and dripped from Lena’s parted lips, as she struggled to keep Kara exactly where she wanted her. She was so big that there was no way she would be able to take more in this position but she tried valiantly, nostrils flared and eyes watering as she began sucking and deep throating, as if she needed Kara’s seed to sustain her.  

“Le-na, oh Rao…” Kara rasped. Her thighs were tensing and her hands more demanding as they pushed at Lena’s head. Bucking her hips up erratically, her breathy groans grew into deeper, more husky growls.  

Kara was close to exploding, and Lena could feel it in the way her cock stiffened and how Kara’s eyes were practically half closed, so heavy with desire that Lena took the chance to quickly pull open her shirt to expose her breasts in a black, lacy bra that barely hid her stiff nipples.  

“You’re so beautiful,” Kara groaned, as if the sight of Lena half undressed pained her on some level. “So good at this,” She praised, lost in her pleasure as it soared higher.    

“And all yours,” Lena gasped out, pulling her mouth free for only a second before she dived hungrily back onto it.    

Kara’s hands held Lena steady as her hips jerked reflexively, a throaty noise erupting from her as she announced, “I’m gonna--”  

“Yes,” Lena moaned wantonly, opening her mouth and pressing her tongue flat against the underside of Kara’s cock as she pumped it fast with her hand.     

The first thick spurt of come covered Lena’s lips and tongue, and she held it there for Kara to see how much she wanted it. She moved so that the next hot spray shot over her neck and dribbled down her throat, and the last two splashed down her breasts and bra. She looked saturated and sticky, and when Kara’s gaze was done devouring the sight of her, Lena swallowed what was in her mouth and licked the rest from her lips.

The sound of Kara’s bell jarred Lena and she stayed on the floor for the sake of her modesty. Kara launched herself clumsily up from the couch and staggered to the door. Zipping up her pants, Kara took the pizza box from the deliveryman and ripped her wallet out of her back pocket to pay. 

Lena stared down at her lap in silence as she considered her next move carefully. Kara arranged the food on the coffee table along with a bottle of soda and cups. 

Picking up a handful of napkins, Lena wiped down her chest as she startled Kara with a question that would instigate all kinds of discussions between them over the next few days. “Do you have any condoms in the house?”
