Force of Attraction - Chapter 2

[Quick note I'm just throwing in here: All in the Risk will be up tomorrow. I'm sorry about the delay, as I know many of you are looking forward to Part 2  - I had some very serious unforeseen circumstances this weekend]. 

Thank you to the top tier patron who shared! (*This story was the patron's prompt for 4 months, so there is two more chapters to go).


Tags: Oral sex (Kara)--*there's a lot of this, in many different explicit and risky scenarios. Oral sex (Lena), sexual discussions/planning loss of virginity; Lena says the word 'slut' once in mentioning how others might view her extreme thirst.





Mentioning condoms might not have been the most tactful approach to initiating a conversation about sex. Lena tied her hair back in a tighter ponytail as she watched Kara almost drop a soda bottle mid-pour. 

“No, I don’t – I don’t have any in the house,” Kara stammered, her face on fire with embarrassment as she glanced down at her feet and flailed nervously. “I’ve been single for a while.” She gripped the frame on her glasses and adjusted them while avoiding Lena’s eyes. Some part of her must have known that sooner or later sex would come up, but from the way Kara reddened, she obviously hadn’t been expecting it now.

Lena grabbed a slice of pizza from the box and ate a small bite as she gave some consideration to her choices. She hated to make Kara uncomfortable, but she believed it was important to talk candidly about sex before engaging. 

“I know it might be a little presumptuous on my part, but I can look into birth control options,” Lena offered. “If there was a pill I could take, I’d rather not use condoms. I really love the idea of feeling you inside of me.” 

Kara choked so hard on a gulp of soda it must have gone up her nostrils, because she clutched at her nose and then sat heavily on the couch. It brought a faint smile to the corners of Lena’s lips and she regarded Kara openly with hunger. Her cool eyes followed Kara’s every move, and although her body language was hard to read because of the jitters in her legs, Lena honed in on Kara’s massive erection. 

“You like the idea of being inside of me without using any protection,” Lena noted with a breathless exhale and set her pizza slice down on a paper plate. Her chest rose and fell faster as she became more excited and breathed harder, glancing down at the enormous shape of Kara’s cock bulging through the fabric. “I just took care of that and you’re already hard again.”

Kara seemed reluctant to acknowledge it out loud, but Lena crouched down in front of her and opened her pants.

Lena was determined to get Kara to discuss it, even she had to use oral persuasion to get her way. Fluttering her tongue along the rim of Kara’s cock, she worked her way up to the notch that leaked pleasure. She sucked on it, gathering it into her mouth and using all of the messy arousal to slide her lips down Kara’s length. Her hand settled underneath Kara, cupping beneath her cock and giving her a gentle squeeze. 

“It amazes me how much you always have to give,” Lena whispered as she moved her hand, feeling Kara’s length against her palm. “It must be because you’re Kryptonian. When aroused, your production count must be much higher than the average human. That makes you perfect for me in every way, Kara, because I think my own sex drive is much higher than average.” 

Lena thought she could spend all day with Kara’s cock in her mouth and made a mental note to test that theory at the first available chance. For now, Lena wanted to show Kara how much she desired her, and somehow that translated to rubbing her face along Kara’s stiff cock and down to where her chin caressed beneath it. She was bolder this time than the last and explored as much as she wanted. Opening her mouth, she followed her own deeper urges to suck on Kara.

Kara must have been especially sensitive or otherwise turned on by what Lena said, because she groaned and experienced a visible shiver of pleasure. 

Lena wanted to prolong this as much as possible, so she took her time stroking Kara’s cock with one hand and softly slurping at her erection. Her lips were almost juicy from it, and her panties became slippery with desire as she moved her tongue in languid licks and felt Kara’s thighs tighten.
 

Kara pushed loose dark waves of hair behind Lena’s ear, but then guided her to look up and sit back.
 

Lena’s lips popped wetly as they let go. She expected some kind of lecture from Kara, something about how they needed to end their relationship, but instead Kara only caressed her neck and gave her a soft look. 

“Have you ever — have you ever been with anyone before?” Kara asked, and a bright burn of humiliation spread over her cheeks as she fretfully nibbled at her bottom lip. “I mean—um, intimately.”

Lena smirked and tipped her head to the side as she stared up at Kara, who no doubt had been with many women in the past, and yet was still so nervous and chivalrous when it came to sex. Kara must have been worried about Lena’s lack of experience and experimenting with her in ways she never had experimented with anyone else. 

“Are you asking me if I’m a virgin, Dr. Danvers?” Lena teased, both as a way to avoid Kara’s initial question and because it sent a thrill through her when Kara’s cock hardened from it. 

Kara fiddled with her glasses and pressed her lips together, falling into anxious habits as she nodded. 

“I know what you must be thinking. Why would I still be a virgin when I’m twenty-three? But the truth is it never felt right with anyone I dated, and I’ve been too busy earning three Masters degrees and writing a research proposal for my Ph.D.,” Lena admitted. “You of all people should know what it’s like to put your professional goals above relationships, considering your accolades. You’re not even thirty yet and you’ve won more research awards and published more books than colleagues twice your age.”

It might have been manipulative to lean forward and swipe her tongue over Kara’s cock, but that was exactly what she did. 

“Are you sure—oh, Rao—are you sure you want me to be—the one—” Kara gasped, unable to finish a sentence with Lena’s lips locking around her aroused shaft.

Lena’s lips curled into a smile in spite of herself, and she was forced to release Kara from her mouth as she arched an eyebrow up at her. 

“I’m absolutely sure,” Lena confirmed. She gave a slow pull at Kara’s erection, mesmerized by how it towered over her when she was in a low crouch on the floor.
 

“You’re the most considerate person I’ve ever met, Kara, and you make me feel safe and loved when I’m with you,” Lena added as she noticed the conflict on Kara’s face, and how she must have been questioning having sex with someone a bit younger and less experienced. 

“Since this started between us, all I can think about is how good I feel whenever you’re in my mouth,” Lena murmured, more than a little distracted by how the skin along Kara’s shaft pulled over the head when she stroked it in her fist. Thick dribbles of arousal poured down her hand and Lena licked it off her fingers.

 

Kara groaned at the sight of it and slumped back into the couch, as if every new erotic act on Lena’s part was almost too much for her to handle. 

“There — there’s one thing I want to make clear,” Kara emphasized, sitting awkwardly to avoid glancing down at Lena while she tried to carry on with their serious conversation. “You — you’re my priority, and I don’t ever want you to feel pressured or like you have to do any of this to keep me interested. I’m — I’m falling in love with you, Lena — and — there’s no expectation on my part at all. We can wait.” 

Kara’s old-fashioned romantic attitudes shouldn’t have surprised Lena, but it thrilled her in all of the best ways to know what she meant to Kara. 

“I think I’ve waited long enough,” Lena insisted with a quiet laugh and dimpled grin, and the dimples remained after she pushed her lips over the tip of Kara’s cock.

 

Even tasting the residues of Kara’s pleasure brought fresh slick to her panties. She gripped Kara firmly while she licked, invigorated by how Kara responded to it. Her wet mouth glided down Kara’s erection, finding it easier than ever to push more inches into her throat. With Kara’s length and girth, it was hard not to gag herself in her hunger to suck. 

It brought a pleasant ache to her jaw when she deep throated Kara and she found a pattern of breathing that let her keep her mouth full of cock longer. An idea came into her head, and before she could think of how it might sound, she asked Kara for what she wanted. 

“Will you thrust into my mouth?” Lena exhaled before sliding Kara’s cock back down her throat, and then she took a few shallower sucks on it while she observed Kara as she was clearly thinking it over.
 

She realized that with Kara she would have to be vocal about her desires, or otherwise the well-meaning professor would continue to treat her like she was delicate. 

If she had been doing this with any other co-ed or professor in their department who had blatantly checked her out in the past, Lena doubted they would care about more than their own pleasure. 

Lena had to acknowledge that she loved the fantasy of Kara using her throat or pounding into her cunt roughly. All sorts of filthy acts were more appealing to her when she factored in Kara. 

It might not have been the smartest to confide these reflections in Kara, but she acted on the sudden compulsion and admitted to all of her inmost desires.

“I love having your cock in my mouth,” Lena husked and stared up at Kara to gauge her response to that. “Some people might call me a slut for being so thirsty for you.” 

Kara took offense to the hypothetical notion of anyone taunting Lena and protectively assured her, “I would never allow that.”

“What if I like the idea of it?” Lena whispered and then fixated on Kara, taking note of her little tells and searching for any signs of disgust. “I’m comfortable being honest with you. I want you and I crave you all of the time. If you used dirty language with me, I would like it. You’ve proven over and over again that you have nothing but respect for me, so I wouldn’t take it as an insult.”

Kara’s brows scrunched inward in worry and her cheeks flamed again, but Lena sensed that it at least aroused Kara to know she was so thoroughly wanted. 

“I always try to be — polite,” Kara choked out, her voice hoarse and parched because all of her fluids were flowing elsewhere. “I don’t think I could ever call you names, Lena — but if you really want me to try, then I’ll keep it in mind. Maybe—maybe someday I’ll try in the heat of the moment.”

Lena was satisfied with that arrangement and took Kara’s cock back into the warmth of her mouth to show it. She rolled her tongue under the stiff head, groaning when Kara proved she had been listening before and forced more into her throat by thrusting. Her lips had to stretch wide for it, and the longer that Kara pumped cock into Lena’s mouth, the wetter her chin became. 

Kara’s hard cock slid through the heated muscles just beyond Lena’s tonsils and she groaned in encouragement.

 

Kara was acting on urges in ways she probably never had before, and her eyes darkened from the indulgence of slamming harder into Lena’s throat. It captivated Lena to get a glimpse of the potential beneath Kara’s calm exterior. She wondered what other hidden, hedonistic desires she could eagerly suck out of Kara.

 

When Kara’s strong fingers fisted into her hair to pull her mouth closer, Lena felt lightheaded with euphoria. All of her excitement liquefied and ruined her panties, and the vibration of her moans must have spurred Kara on because she continued to thrust, causing Lena’s eyes to water.

 

Kara suddenly loosened her grip, and Lena saw the flicker of worry as it passed over her face. She had to stop Kara from retreating by grabbing at the belt loops on her lowered pants.

 

Lena refused to be denied this, because her red eyes and mascara streaked face had nothing to do with being upset; it was just the messy consequence of gorging herself on Kara’s incredible cock. She pleaded with whines and soft gagging sounds as she pushed her mouth down on Kara’s erection until finally she thrust upwards again.
 

Lena swallowed while massaging Kara’s cock in gratitude. She handled Kara with adoration, and was rewarded with a throaty groan. It must have felt amazing because Kara’s hips jolted forward and for a few moments she seemed only to be focused on pounding faster into Lena’s throat, despite the way she gagged and salivated.

 

“Oh fuck, Lena…” Kara blurted in shock, her face flushed and her legs beginning to tremble.

With a few more fluid pumps, Lena locked her lips and Kara shot come all over her tongue. As Kara continued to erupt, Lena sat back and took warm blasts of seed to her face, until it looked like she was covered in a drippy ice cream treat. It must have been an obscene sight for Kara, because she was muttering apologies, but Lena calmed her down by asserting, “I want this.”

 It took her a while to lap up all of the thick pleasure. None of it went to waste, and as Lena savored the last of it, she realized Kara was staring at her in slack-jawed fascination.

 Kara understood advanced kinematics and concepts in astrophysics that even other experts seemed to find challenging, but she was clearly  baffled by how much Lena loved to suck her cock. Between conversations about their interests, work and developing a Kryptonian birth control, Lena spent the rest of that night with Kara’s cock in her mouth. Even afterwards, when Kara drove her home, she had questions about Lena’s predilections surrounding oral sex. 

It came up again when Lena proved to be insatiable at the lab and they had a serious conversation about it one day over lunch. 

“If I needed to have you in my mouth at least three or four times a day, would you allow it?” Lena asked softly, as if she was just asking for more frequent breaks at work, and not requesting something far more immodest and risky. 

Kara almost poured her coffee down herself in distraction instead of sipping at it, and she put her cup down on the table promptly in an attempt to appear unfazed by the question. 

“Three or four?” Kara reiterated, her eyes glazing slightly before she cleared her throat and fixed her glasses by the frame. “Need is a really strong word for—well—for that.”

Other than the pink tinge to her cheeks, Kara looked calm and collected, but Lena knew better and her hand subtly slipped beneath the table to clasp the bulge beginning to form in Kara’s pants. 

“I assure you it’s an appropriate word for it.” Lena coyly stated, stroking her warm palm over the hard length just to feel it stiffen considerably. “Don’t you need it, Kara?”

It was dangerous to whisper such things in public, but Lena couldn’t contain herself as her hand traced Kara’s thick erection through her pants. She swirled her fingertips over the broad shape of the head and watched as Kara sucked in a stuttered breath. “All of that pent up ….energy has to go somewhere,” She insisted with a sultry purr, her tongue swiping over her lower lip. “So why not my mo—”

 

“More coffee?” A waitress asked, stopping at their table.

Kara nearly bashed her knees on the underside of the table, she jumped so violently, and Lena returned her hand to her own pocket to pull out her phone so as not to arouse suspicion.

“Yes,” Kara blurted at Lena, then blinked at her half full cup and shook her head at the waitress, “I mean no. No thanks. Just the bill, please.”

The waitress shrugged with a bored roll of her shoulders and uttered, “Sure, no problem,” then wandered off to the next table.

Lena continued to stare at her phone, although she flashed Kara a mischievous grin while the waitress’ back was turned towards the cash register.

 

“I can’t help how I feel about you, or that I find you completely irresistible.” Lena playfully raised her eyebrow as she pulled her coat back onto her shoulders. 

The waitress delivered their bill promptly, so Lena had no time to continue her tantalizing game – but when they were back in the privacy of the lab, she sat down beside Kara and opened the fly on her black trousers. 

If anyone came into the lab, they would have assumed that Lena and Kara were huddled together in front of the computer checking the results from one of their models. Instead, Kara was working out a different chemical compound to act as a contraceptive method for Lena, while Lena in turn rubbed her to complete stiffness through her boxers. 

Kara was trying to control herself if the tight clench of her jaw was any indicator. She had her eyes focused on the computer screen and the more she attempted to resist, the more Lena wanted to see her give in to desire. 

“I’ve been thinking about the first time you’re going to be inside of me,” Lena confessed in a whisper, then glanced down at Kara’s lap where her cock poked through her pants. A rivulet of Kara’s precum poured from the tip and Lena bent over to lick it away. 

“You’ll be going away in two weeks for a conference, and when you get back, you’ll be aching for a good release,” Lena whispered and slipped her hand under Kara’s cock. “I want it to be inside of me. Can we discuss it, Kara, and plan it all out before you go?”
 

Kara’s hands froze across the keyboard and her nostrils flared from her effort not to react to the sweet temptation that Lena was so adept at delivering. It was a sight Lena enjoyed seeing — Kara’s whole body as rigid as her cock. All that hard muscle and the strength Kara possessed, useless against the soft warmth of Lena’s hand and mouth.
 

Lena palmed below Kara’s cock and gave a gentle squeeze that evoked a quiet groan from Kara. Another bead of desire formed and dripped like icing down Kara’s straining shaft and Lena traced it with the tip of her tongue.

“Why don’t you tell me what you’ve been thinking and we can work it out?” Kara asked, her lips dry and voice scratchy as she glanced at Lena.
 

“While you’re away, I’ll be staying at your apartment to look after your plants, and with your permission, I’m going to sleep naked in your bed,” Lena confided and gave a gentle tug at Kara’s cock, enveloping it with her fist as she stroked faster. “I want to video chat with you every night and show you my pussy, Kara. I know you’ll be busy, but I hope you’ll have some time to look at me each day and think about how I’m going to be yours.” Her soft mouth tickled against Kara’s neck as she leaned into her, revealing all of her private wishes in the sweetest whisper.
 

Lena had plenty of other secret desires, but she waited to get Kara’s honest reaction to a few of her fantasies before laying them all out.
 

It was unclear which part caused Kara’s eyes to glaze over, but the way her cock strained in Lena’s hand could only be a good sign.
 

“You really want to tease me, don’t you?” Kara questioned, her voice breaking as her face expressed deep curiosity.
 

 Lena nodded and slid her hand down to tease Kara’s solid cock with her fingertips, then basked in how that caused the Kryptonian to groan. It was depraved, and on some level Lena knew that, but she couldn’t deny that she had feelings for Kara and every naughty urge that came to her mind was something she only wanted to explore with Kara.
 

Kara must have seen the deeper emotion in her eyes, or the raw desire on her face, because she opened her mouth in surprise and then swallowed thickly. Her face turned a pretty pink and she chewed her lip in silence for a moment. Lena knew she was thinking it over and gave her cock a squeeze that helped Kara find the courage to say, “We can do it, but there are some risks, Lena. You would have to wait for me to call you on those nights to ensure I’m alone.”

“I promise to wait for you to phone me first.” Lena stressed, because she would do whatever Kara asked to protect her career and reputation. The risks they had been taking were always calculated, with a low chance for discovery, but Lena’s need for Kara was growing to new extremes. 

 “Can you please fill my mouth with your cock now?” Lena whispered and shifted onto her knees in front of Kara, in a position that would conceal her from view if any of the other astrophysicists in the department stopped by. 

Lena freed Kara’s cock from her pants and boxers, dragging them down to mid-thigh. Her lips stretched obscenely wide as she ambitiously took Kara’s cock in her mouth. It filled her throat completely and she slurped noisily, giving it attention with her tongue. She planned to do this until Kara stopped her and put her mouth to much better use.

 

Kara’s hand settled atop Lena’s head to stroke her hair in praise. She gave a breathy exhale as she reclined in her seat to watch Lena tend to her so passionately.
 

Stroking her fingers through Lena’s dark tresses in adoration, it seemed like Kara was on the verge of directing her, but her soft groan of need was cut short as the sound of a knock rang through the lab and the door pushed open. 

Lena hadn’t been expecting anyone to interrupt them and she felt Kara freeze in fear.

“Dr. Danvers, I was wondering if you could spare a few minutes to go over my thesis. I can’t seem to work out—”

Kara forced a smile onto her face that was more of a grimace and attempted to sound casual as her neck turned bright pink. “Mr. Monel, as much as I’d like to assist you, I’m not your advisor. As I’ve told you previously, and at length…”
 

“Hey, call me Mike.”

The sound of a chair being pulled out followed by a happy grunt as the weight of person landed in it alerted Lena that this guy was going to stay, and that shouldn’t have given her a thrill, but there was something incredibly naughty about being under Kara’s desk, doing things she shouldn’t be while they were working.

“Mr. Monel, please, now isn’t a great time for me.” Kara insisted, schooling her features into what Lena liked to call her academic face as she grabbed the frame of her glasses and adjusted them.

“C’mon, Dr. Danvers, I need you more than your computer does. If you give me ten minutes of your time, I’ll buy you the best beer you’ve ever tasted. How about it?”

“I don’t fraternize with students,” Kara stated sharply.
 

Just former students and colleagues, Lena mentally supplied.
 

She wondered if Kara would be able to feel her smirk as she pressed her mouth down over the shining head of Kara’s cock.
 

Her tongue slipped into the furrow at the top and she licked at the glistening drops of Kara’s passion for her. 

Lena felt her pussy react as Kara’s aphrodisiac arousal coated her tongue. She might have moaned, but she blocked the sound with Kara’s cock.

Mike must have spent a few seconds pondering ways to convince Kara, because he shuffled his papers. 

“I’m really struggling with interpreting this data,” Mike sighed in defeat, switching tactics in a clear bid to sound pathetic enough for Kara to take pity on him. “Is your assistant Ms. Luthor around? I bet I could ask her my questions and we wouldn’t even have to bother you.”

Kara groaned at that, both because Lena was intently sucking her cock at that very moment, and because she obviously hated the idea of Mike taking up any of Lena’s time. 

“I’m sorry,” Kara huffed in aggravation, and Lena could practically see the way her glasses must be steaming up from sexual frustration. “Ms. Luthor is busy right now, doing – a very special task for me.”

 

Lena pumped her lips until Kara’s huge erection was lodged completely in her throat and she gulped down hard.

 

 Kara’s thigh muscles tensed and her feet shifted wider apart so that she sank lower in her seat. The slight movement pushed the head of her cock deeper into Lena’s throat and Kara exhaled roughly through her nose, her gaze flicking down to look at Lena subtly in the guise of checking her watch, as if she was annoyed, and not incredibly turned on by Lena’s clandestine antics and her wonderful mouth.

 

“Please, five minutes,” Mike whined. “I don’t think Dr. Schott likes me very much and I want to show him I have what it takes. I’m begging you, Dr. Danvers, I need this more than you know.”

Lena could feel delicious tension in her abdomen and cunt just from having her throat full. She paused, unable to push her lips over the thick cock because of the noise and risk of gagging, but she could experience the steady, throbbing pulse of Kara’s thick erection. The ache in her jaw from having her mouth so wide open heightened the experience, as she thought about what it would be like to have Kara inside her pussy.
 

“I’ll give you two minutes.” Kara countered sternly, and Lena knew she was desperate to buck upwards.
 

“Yes! Thank you,” Mike cheered. “You’re a life saver. Can you just skim this and tell me if it makes sense or—”

Kara moved suddenly, purposefully, the jut of her hips sending the broad tip of her cock past Lena’s tonsils, then she rocked slightly, stimulating herself with the hot contractions of Lena’s throat as she hummed in satisfaction. The papers in her hands were an excuse to make noise, and the soft rustling gave Lena the opportunity to bob her head with painstakingly slow momentum.
 

It tore a groan from Kara and she slapped a hand onto the desk. Lena didn’t hesitate for a second. She needed this, and Kara must have known it because she thrust the papers back at Mike and muttered in a rush, “First half good, second half not so much. You need to cite your sources and don’t deviate from your subject. You aren’t telling a story. You’re compiling data and facts. Present them better.”
 

“Thanks Dr. Danvers,” Mike replied with a broad grin that Lena could hear rather than see. “You’re the best, but seriously, I owe you that beer. Maybe after hours, I could pick you up, and—”
 

“Get out, Mike.” Kara snapped, and it wasn’t because she was ill tempered. Her hand slipped under the desk and onto Lena’s head to encourage her to take more, her pent up frustration and need overcoming her senses as she thrust her cock into Lena’s throat.

“Yup, got it, thanks again!” The sound of the chair screeching back was quickly followed by the door to the lab opening. 

It had barely slammed shut when Kara groaned and sat back to resume watching Lena. 

“Do you have any idea how hard it is to function when you’re doing that?” Kara husked out, her tone filled with adoration, even as her eyes were dark and hungry.

Lena merely raised her eyebrow at Kara in playful defiance and tried to fit more of Kara’s cock in her mouth. She moved her tongue while she sucked down to the base. 

“I know I’m quite naughty for getting on my hands and knees under your desk, but I truly couldn’t wait a minute longer,” Lena muttered, her nose and face rubbed red from the friction, but she had no plans of ending this until she was satisfied. 

Kara grunted at Lena’s eagerness. Somehow Kara seemed charged up and much more assertive than before.

 

As Kara stood, Lena moved onto her knees in an upright position so Kara could push into her throat. It was so rough and animalistic that Lena could no longer keep her lips in a tight latch around Kara’s cock. She choked a few times, but stared up at Kara with fierce longing in her eyes. This erotic show of dominance brought such a sensual fire to Lena’s favorite act. Her pussy was fluttering in time with Kara’s strong thrusts and she experienced raw pleasure like she had never experienced in the past.
 

Kara’s seed shot everywhere, into the back of her throat and over her lips and in warm splatters all over her face. At the same time, Lena’s thighs clamped together in sexual gratification and she whimpered. 

Lena tilted her head back, swallowing with gulp after gulp until Kara tucked her cock back into her pants and sat down. 

Lena was still glowing from her own orgasm and her pussy still clenched from it. 

“Kara, I—” Lena stuttered out, and then halted because she was uncertain how to explain what had happened. “I came from that.” She was self-conscious about admitting it, even after all they had done together and all of the dirty things she had already divulged. 

Lena wasn’t sure what reaction she was expecting, but Kara stalking off hadn’t been it. She turned to follow her with wide eyes, only to observe Kara tugging the blinds closed to prevent anyone walking by from look into lab. Kara locked the door for good measure and rounded back towards Lena with such intensity that a soft, breathy whine escaped her lips and she felt her pussy clench harder.

 

“I would like to see that.” Kara whispered, her voice thick and rough from lust as she helped Lena onto her feet. With gentle but strong hands, Kara lifted her to sit on the desk demurely before she sat down in her chair and scooched closer.
 

“If you’re comfortable showing me Lena, I want you to raise your skirt, but it’s perfectly fine if you choose not to,” Kara added.
 

This direct and confident approach had Lena’s stomach flipping in excitement and she squirmed pleasantly on the desk as she bit her lip coyly. They were breaking all the rules today, it seemed. Despite how voracious she was to have Kara’s cock, Kara had always seemed reluctant to overstep boundaries and the biggest one had been that she never looked at Lena’s body. Apart from seeing brief flashes of her in underwear, Kara had avoided this level of intimacy.

 

Catching the edge of her short skirt, Lena hiked it slowly up her thighs just to drink in the desire that Kara exhibited. She leaned back as Kara moved forward, and Lena parted her legs to show the soaked fabric of her lacy panties, but she wasn’t done there. In a bold move, Lena coaxed the slippery gusset aside and used her fingers to spread her pussy lips, fully exposing her pink labia and still clenching hole.
 

“Oh Rao, Lena...” Kara breathlessly rumbled in awe, her jaw slack and her face so close that Lena could feel every warm puff of breath as it cascaded over her thighs. “You truly are a beautiful marvel.”

“Can I taste you?” Kara whispered as she reverently parted Lena’s pussy lips, and although Lena felt a little nervous about having Kara’s mouth on her, she nodded and Kara bent over to lick at her sensitive clit. Lena moaned at the unexpected intensity of the sensation and clawed at Kara’s shoulders to prevent herself from sliding off the desk as her knees tried to come together in reflex. 

“Fuck, Kara, I never expected this to feel so good,” Lena groaned, overwhelmed by how Kara’s tongue moved against her body, circling her bead of nerves and swallowing down her intimate flavor. In the past when she had tried this with other people she dated, it had never felt like this – so pleasurable that her limbs were shaky and it affected her already strong libido. Her cunt clutched inside without a cock to wrap around and Lena spread her legs open as Kara brought a fingertip down to feel the soft contractions of desire. 

“Do you feel how ready I am for you?” Lena asked and the temptation to beg Kara to push inside of her was so powerful that she considered giving up her virginity right then and there. 

“Yes, you’re so wet, and you’re going to come in my mouth.” Kara pushed her legs outward and licked at her clit, finding a rhythm that made Lena move in response. She moaned out incoherent words as Kara puckered her lips and sucked her with passionate, soft noises of delight. 

Lena whimpered and leaned back, holding onto the edge of the desk until her hands hurt from it, and her cunt was slick from arousal and Kara’s mouth. It felt better than she predicted to have Kara touching her, manipulating her clit with her tongue, and Lena knew that once they had sex she would struggle to concentrate during the day at the lab without this kind of attention.
 

Kara pressed her lips insistently around Lena’s clit, and a small spasm of need went through Lena’s body. She rocked into Kara’s face, chasing the desperate feeling inside. It was a powerful motivator, one that had all of her muscles straining in a coordinated effort for pleasure. 

“Ohh—oh fuck, mmm, Kara,” Lena moaned, rubbing her cunt against Kara’s chin as she licked at her clit with wonderful speed. She came hard and breathless like that, then limply sat back against the desk with a face bright pink from exertion.
 

From her vantage point, Lena could clearly see the erection forming in Kara’s pants again and she knew that Kara was gazing at the delicate and fragile paler pink that signified that nobody had been inside her.

 

“This is where you get to go,” Lena dared to murmur, her sultry words wrapping around Kara seductively and earning a moan. “After your conference, this is all yours.” She punctuated her statement by lightly stroking her middle fingertip over the thin barrier and then around her opening before she fixed her panties and pulled down her skirt with a mischievous smirk at how flustered and aroused Kara appeared to be.
 

“You look like you need a coffee.” Lena teased, quirking a dark eyebrow as she lowered her eyes meaningfully to the straining bulge. “Extra cream.”

 

From that afternoon on, it was impossible for them to resist each other, even at times when it would have been more convenient to wait.
 

Kara tried to continue being careful, but most days she was painfully erect at work and spent more time disappearing into the bathroom than at her desk.
 

Even with Lena using all of her breaks to suck on Kara’s cock, the Kryptonian was perpetually aroused and too polite to ever interrupt Lena while she was busy tweaking a model or writing up their findings.

Lena confronted her about it one afternoon by following her into the restroom and snagging ahold of her belt. 

“You leave for your conference tomorrow, and you haven’t come in my mouth nearly enough,” Lena accused and cocked her head to the side with a smile when Kara seemed like she might deny it. 

“But—you—you just spent your entire lunch hour—” Kara blurted, only halting when she realized that Lena was messing with her.
 

“It seems like no matter how much I suck you, you’re always ready to go again,” Lena grinned and opened Kara’s fly to peek into her boxers at the eager tip of her cock, already gushing with desire for her. “Are you going to survive a whole week without me?” 

They were standing in the middle of the bathroom, where anyone could see them if they pushed through the outer door, and Lena was brazen enough to drop to her knees and pop her lips onto Kara’s blunt head.

Kara hissed from the onslaught of sudden pleasure and the surprise of finding herself out in the open with Lena’s red painted lips wrapped around her cock. She glanced over at the stalls wildly, and then the entrance, but she didn’t tell Lena to stop. Instead, she groaned out a pained and shameless noise that faded as she confessed, “I’m not sure. I — I really don’t know how I’m going to get through the week without you by my side.”

Kara looked ashamed of herself, as if admitting that she needed this as much as Lena made her a bad person. Lena’s heart melted at that and she double downed on her effort to chase away the negativity and prevent Kara from losing herself to any thoughts that might have been running through her mind. Lena refused to allow it, and with every fast slurping pull at her cock, Lena demanded and kept all of Kara’s attention.

The urgency of it all sparked a deep-seated need in them both and Kara’s hands finally settled lovingly on either side of Lena’s face. She stroked her thumbs over her high cheekbones and Lena moaned softly, nodding and pleading as best she could with her mouth full as Kara questioned her with her gaze alone.
 

Do it, Lena silently begged, her expressive green eyes trained on Kara’s face as she sucked harder. Fuck my throat like it belongs to you. Take what you need like it’s your right to have me on my knees in this bathroom, so if anyone walks by, they’ll know how hungry I am for you.

She must have conveyed the message well, because Kara’s eyes darkened until all the brightness was cast in shadow and her unending hunger for Lena prevailed. Lena opened her mouth wider in preparation, and Kara’s essence pooled and dribbled down her chin as she unbuttoned the top of her shirt to show off her breasts in a sexy lace bra that matched her panties.
 

Small, keening whimpers escaped Lena in her excitement as Kara’s strong fingers wove into her hair, and she half gagged, half moaned when Kara thrust hard enough to lodge her cock at the back of her throat.
 

 Lena grabbed for Kara’s belt to keep herself upright and accepted the pace of Kara furiously pumping into her before they got caught in such a lewd and compromising position. The noises she made were obscene, interspersed with soft grunts and low moans from Kara as she forced her erection past Lena’s tonsils and watched the way her pale throat bulged with every powerful thrust.
 

“Lean back,” Kara husked, lost in the moment. “I won’t drop you.” She promised, and cradled the back of Lena’s head as she squatted lower to truly drive herself deeper down her throat.

It was a new angle and Lena moaned wantonly as she felt the muscles of her throat relax and contract to the sizable intrusion. She swallowed around Kara earnestly, and felt dizzy and desperate from this carnal act of submission. The way her pussy began to throb, Lena knew she could come from this alone. God, she wanted to come from this.

 Lena loved the force behind Kara’s lunges and how the gentleness of her hand contrasted with it. Kara slammed into her at a desperate speed, only to slacken to harder but slower thrusts. The filthy sound of Kara slapping at her chin shouldn’t have thrilled her as much as it did, but the resounding noise was so exhilarating. 

From the way Kara tightened, Lena sensed she would be covered in come and opened a few more buttons on her shirt in readiness for it. Her pussy clenched in excitement as if Kara was already releasing inside of her. 

Kara moved at a more deliberate and frenzied pace, until her groans bounced off the tiled walls and she filled Lena’s throat with seed. It overflowed Lena’s mouth and spilled all down her neck and breasts, and some even stuck to her wavy dark hair. There was so much to clean up that in their scramble not to be seen, Kara just re-buttoned her shirt over it and guided her to the sink. 

Lena licked away what she could and Kara washed the rest of it from her face and hair. It all happened so fast that neither of them spoke of it until they were standing back in the lab.

“Kara, I want to do that again tonight at your place,” Lena admitted in a hoarse whisper, her throat still sore from the vigor of what they had done in the bathroom. “I know it was a bit reckless, but I loved every minute of it.” 

Kara had her back turned towards a lab table and she was fiddling with the items in front of her. She lifted a few notebooks and a stack of papers, along with other belongings from her desk that she must have needed for the conference. 

“I—I think we need to be more careful, Lena,” Kara haltingly conveyed, as she pushed the strap on her bag up onto her shoulder. “Not because I’m worried about getting caught, but because I want to be careful with you. I never want you to feel — well, dirty or used —”

“Kara, it turns me on to feel dirty and used,” Lena explained and reached for Kara before she could retreat or develop more guilt. “I also feel loved. It might not make sense to you and I don’t really have a deep understanding of it myself. I’ve tried telling you about this before, but when we’re having sex, I want you to be rough with me. It gets me off.” 

Kara squinted in uncertainty behind her glasses, sighing in worry, but then she nodded as if she could accept Lena’s proclivities and handle them. 

“Okay, Lena, okay,” Kara whispered and gathered Lena into her arms right in the middle of the lab, embracing her in a very unprofessional way. “As long as we continue to discuss it and you check in with me every time we do something like that, I can take care of your needs. Let’s go back to my place. I’ll make you dinner and you can spend the night.”

With a soft rattle in her pocket, Kara pulled out a bottle with the birth control pills they had been working on since Lena brought up the topic of sex. “I have this for — for when I return. I finished it a few days ago.” 

Lena eagerly reached for the bottle, but she noticed Kara was still nervous and biting at her bottom lip. 

“Kara, I know you still have concerns, so please think of it this way: I’m going to lose my virginity to someone who truly cares about me, who is only rough in the ways I want her to be rough with me.” Lena slipped the bottle into her coat and went to grab all of her work while she thought about how lonely she would be at the lab for the next week without Kara. 

It was the impending absence that kept Lena’s mind preoccupied while Kara loaded their bags and all their work into the backseat of the car a little while later. As they buckled up and started the drive back to Kara’s apartment, Lena had trouble shaking her feelings of loneliness. She knew it was foolish to miss someone already, especially over such a short amount of time, but seven days was a whopping one hundred and sixty-eight hours. That was, at a minimum, forty-two times Kara’s cock wouldn’t be in her mouth, given that she was averaging at least six times a day or more.
 

The neediness Lena experienced was how she imagined a drug addict felt when they were going cold turkey, and she simply couldn’t wait to get home, or for Kara to cook dinner before she could wrap her lips around her wonderful cock. It was wasting time that she should be cherishing, and so she blurted rather unceremoniously, “Hey, I have an idea, let’s go to the drive thru!”
 

Kara jumped out of her own thoughts and swung her startled gaze towards Lena as she exhaled shakily. “Ssure, what are you—what are you in the mood for?”
 

“Sorry,” Lena gushed, and soothingly placed her hand on Kara’s thigh to rub the fright out of her. “How about Big Belly Burger? I know between us we could probably cook something but why risk your kitchen?” It sounded so reasonable that Lena almost forgot that she had other plans.
 

Mid-week during the evening rush hour meant the popular burger joint drive-thru would be as good as gridlock, and Lena was counting on that. 

“I can never say no to a burger,” Kara grinned, and switched lanes to head in the direction of the nearest chain. “Do you know what you want or will you need a minute once we get there?”

Lena glanced at Kara from under her dark lashes and coyly licked her lip. “I know what I want.” She seductively whispered, and her tone alone caused the soft bulge in Kara’s pants to subtly stiffen. She smirked deviously, her hand settling so close to Kara’s cock, but innocently enough that she could get away with it. “I’ll have the classic meal with a vanilla milkshake.” She murmured and squeezed Kara’s thigh. “What do you want, Kara?”
 

“I uh—I—” Kara blushed furiously, her mind definitely in the gutter as she stuttered over her words. “Prob-probably the same.” She finally managed, and Lena hummed approvingly and traced the shape of Kara’s forming erection when she pulled into the lane for the drive-thru.

 As predicted, the place was backed up, and Lena smirked at that because judging from the tent in Kara’s pants, so was she. “Perfect,” She murmured happily, and seized the opportunity to tug Kara’s zipper down as a truck pulled in behind them, trapping their vehicle in the line.

Kara’s eyes widened in surprise and she frantically looked around as she hissed, “Lena, what are you—”
 

“Shhh, just let me. Try to look bored so nobody notices how insatiable I am.” Lena encouraged, and popped the button of Kara’s pants open to slip her delicate hand inside the fabric. She fondled Kara’s erection through her boxers, making sure to caress and squeeze her with just enough pressure to have Kara sinking back in her seat, her lips parted in pleasure, despite the way she gripped the wheel roughly.

“You’re going to be gone for a whole week and I can’t go another second without tasting you.” Lena confessed, and pushed Kara’s boxers down to rest the waistband under her cock, exposing her fully. “I’m going to miss you so much.” She whispered, unclasping her seatbelt to lean over, but instead of taking Kara’s cock into her mouth, she gave into her baser urges and began to nuzzle into the thick shaft.

She rubbed her lips, cheeks and chin over Kara’s huge erection. It was a form of adoration that Lena had only bestowed a few times before but it felt so natural to rub her face over Kara. She gave soft, feather light kisses that left sticky red lipstick over the sensitive skin, and the gentle expression of love must have turned Kara on all the more because the slippery warmth of precum dripped onto Lena’s hand and she moaned happily.
 

The car moved at a snail’s pace, then stopped, and Lena knew they had at least ten or more minutes before they got to the speaker, and at least another five after that before the window, which gave her the chance to draw this risky experience out.
 

Lena continued to shower Kara’s cock with attention. Her tender kisses became open mouthed and she licked lightly at the strong vein that ran along the underside of the shaft. She sucked at the head, lavishing it with her tongue the way she would devour a popsicle, and rubbed her face into the leaking precum until her cheeks were sticky with it.

Kara was breathing heavier, and one of her hands subtly moved from the wheel to stroke over Lena’s hair without urging her to rush.
 

Lena whimpered in appreciation and rewarded Kara by sucking on her. She drew Kara’s cock into her mouth, moaning around its size until Kara groaned — then she released it. Lena took her time, stopping whenever Kara moaned and grinning deviously when she felt Kara tighten under her tongue.
 

“I think you like it when I build you up like this and deny you,” Lena lilted seductively. “I bet you would have already come if I just kept you in my mouth for a second longer.”

Kara made a strained noise that Lena took for confirmation and then she returned her hot mouth to the Kryptonian’s cock. She worshipped it right up until they reached the speaker.
 

Kara’s poor cock was so rigid that the head was a painful looking reddish-purple, and Lena blew cool air over it.

“Welcome to Big Belly Burger, what can I get you?” crackled the voice from the speaker and Kara accidentally groaned.
 

“Two classic meals with a coke and a vanilla milkshake.” Lena supplied, and Kara repeated the order word for word and pulled forward.
 

They were only two cars away from the window, and a car from the second ordering bay had flanked them on the other side as if trying to push ahead. 

“If this guy pulls up beside us, they’ll be able to watch me. I bet his partner isn’t half as talented with her mouth.” The hypothetical risk had both of them excited and Lena finally wrapped her lips around Kara’s broad cock and took her straight into the back of her throat, gagging and slurping as she bobbed at a frantic pace.

Their car moved again, and Lena moaned at the thrill of it all. The panic that radiated from Kara had her pushing Lena’s head down until Lena swallowed and gagged around her enormous cock.

Lena whimpered as Kara held her in place, keeping her cock deep in her throat as she bucked up to try and fuck her mouth. It was frantic and dirty and Lena felt absolutely naughty at having herself held in such a position. Her panties were flooded with her own arousal and her pussy was aching with need as she sucked harder. Kara let out a strangled cry and held Lena’s head down, shooting the first jet of come down her throat before letting Lena up for air.
 

 Pulling back with a gasp to greedily inhale oxygen, Lena opened her mouth and managed to get another spurt across her tongue, with the rest hitting her face and her shirt. She stroked Kara to get the last few drops out of her and licked it from her fingers before slipping her cock back inside her boxers and hurriedly doing up her pants.

There was no time to clean herself up, and Lena grinned mischievously and angled herself towards her window as Kara flung way too much money at the guy handing over the food. She passed off the drinks to Lena, who immediately popped the lid of her vanilla shake off and exclaimed dramatically, “Oh no, I just dumped it all over myself.”
 

“I don’t know if I should be upset or impressed by how clever that was,” Kara muttered under her breath as she drove off. 

Lena replied by quirking a dark eyebrow. “Impressed, obviously.” She teased, and Kara’s lips twitched into a slight smile, despite the worry that creased her brow.
