“So, I've been wondering— and you don’t have to answer— but is your dick different from humans?”
You say the words without even looking up from your textbook and notebook. A pen continues to twirl between your fingers as you absentmindedly fidget. The choking noise that fills the air concerns you for half a second, forcing you to look over your shoulder and at the man who was quietly going through his articles on his laptop before you rudely interrupted him.
“You haven’t talked in hours,” he mutters, referring to how you crashed his apartment just to study. He removes his glasses off of his face– frames that he doesn’t even need to wear– to drag a hand down his face like it would wipe away the absurdity of your question. “And this is what you say?”
“My anatomy class finally moved on to sex,” you say, as if that was supposed to explain anything.
“… Right.” Clark looks exhausted. He probably wishes he never opened his front door to you, but here you were. Well, even if he didn’t, you could always use the spare key that he gave you ages ago. “You know, I think I like you better when you’re not talking.”
You roll your eyes at his sass, “C’mon. You know why I'm asking this.”
Of course he does. You were the first person to know of his abilities— right after his Ma and Pa. You'd been there to watch him soar into the sky for the first time, finally unafraid. You watched him discover ice breath, and remembered how distraught he was as he looked at you.
Clark sighs, chest rising and falling dramatically with the breath. “My… reproductive organs are similar, from what I can tell.”
“From what you can tell,” you repeat, raising an eyebrow.
“I didn’t exactly grow up with Kryptonian anatomy lessons,” he shoots back immediately. “I haven’t seen a spliced Kryptonian in a museum— a body donated for science and research.”
You pause, then shrug slightly. “I guess.”
He huffs. Actually huffs, like he’s throwing a mini tantrum over your lack of thought to your question. Despite it, he still settles back onto the couch. His muscles no longer feel locked in place, he can breathe normally—
“So you don’t have an alien dick?”
“Sweet lord— what are you going on about?” he whines, looking at you with pleading eyes. You ignore it in favor of expanding your knowledge on his biology.
“You know,” you say, waving a hand in the air, “Some of the rifts— there’s documents on the corpses that come through. talking about how some male presenting aliens have both uterus and testicles, like they can impregnate and be pregnant, too—“
“I don’t have a womb,” he says, followed by your name falling from his lips in exasperation.
“But are you sure?”
“You know those released documents also included strong evidence that those aliens also had a menstrual cycle,” he quickly says. Clark moves his laptop off of his thighs, and leans forward with his elbows on his knees. He’s one second away from burying his face into his hands. “I haven’t— I think I would know if I was bleeding from my pen… from my thing.”
Clark's ears are red. Bright red. He can’t even hide it.
Suddenly, your questions are no longer out of simple curiosity. Now, you want to poke the bear. Except the bear is too sweet and kind to tell you to knock it off, to get out of his apartment, and to leave him the hell alone.
“Your thing?” you tease, a smile spreading across your face. “Your cock, Clark.”
“Do you have to be so vulgar?”
“It’s basic anatomy.” You cross your arms over your chest. “One that you claim to have.”
“I don’t—!” He runs his hands through his hair, clearly stressed. You can’t help but giggle at the sight. “I don’t claim to have regular anatomy, whatever that means.”
“So you admit that your body is biologically built differently.”
“I mean, yes, but not like that!”
“Like what?”
“Please,” he groans, nearly desperate now.
“Ooh, begging,” you say as your grin spreads even wider. “Are you trying to keep Kryptonian biology a secret?”
It doesn’t take much for him to break. You knew that. Always have, and always will. Clark was scarily easy to bait.
“My dick is normal!” he finally shouts, face still flushed. You swear he’s sweating, too.
“But how do you know that?” you ask. You’re not even trying to hide the lilt in your voice. “You compare lengths in the locker room in school?”
“Oh my— stop. please.”
“So guys don't do that? That’s just a myth said online?”
“You’re not totally off,” he quickly says, only to pause a moment later. “Can we talk about something else? Anything else?”
You pout at him, giving him your best pleading eyes you could muster. For someone made of steel and ice, this man melted at the sight of you. He always did.
A deep sigh escapes his chest as he leans back into the couch. “My college ex said my… penis… was above average. I haven't seen other men’s… things, but i’m assuming since she didn’t have an issue with it then it has to be normal.”
Your eyebrows raise. “Do you not watch porn?”
Your name falls from his lips in utter shock, matching the look on face. “You do?”
“You don’t?”
Clark stares at you, as if he’d been slapped with a bucket of freezing water. You can only stare back, waiting for his response.
“… No,” he finally mutters.
“Huh,” you say, taking in the sight of him. Even seated, he’s large. If you stood in front of him right now, you’d barely be taller than him. “Well, it makes sense that you’d be above average. with your height and all. Do you think that is also Kryptonian?”
“I don't know.” Clark shrugs, and it seems like the embarrassment of the topic is slowly melting off of him. “Probably?”
You hum, contemplative. “So, your dick doesn’t have ridges on it? Like spiky nubs along the shaft? Do you think your sperm count is higher than the average human male? Must be stronger, too. I wonder if a normal human woman would be able to carry your children to term without complications.”
A frown takes over his face at your rapid fire questions and commentary. Though he doesn’t look as bothered as he was earlier. It's as if he’s really thinking about it this time.
“I would really hope that whoever carries my children won’t have any complications, but that’s another thing that I wouldn't know until the time came.” Clark's pointer finger taps thoughtfully on his knee as he continues to think, “All of your questions have to do with research that hasn’t been conducted on me.”
“You didn’t answer my question about the appearance of your cock, Clark.”
This time, a pretty red takes over his face. “Why are you so intrigued?”
“Just answer, or I'm gonna demand you to just show me so I can find out,” you groan.
“If I do show you, would you stop asking?”
It’s your turn to freeze in place, blinking at him. He's still the shade of a tomato, but he’s not cringing at his words. If anything, he seems determined. like this would really shut you up.
“Take your pants off then,” you dare.
Clark, ever so obedient and kind, moves. his hands reach for the button of his jeans, so certain and sure.
Suddenly, you realize how close the two of you really are.
You grew up together with neighboring farms in Smallville. The two of you used to sleep in the same bed as children when your parents dropped you off at Kent's for a sleepover.
As a child, the two of you used to change right in front of each other. Even as a budding teenager, you didn’t feel the need to hide away from him, though he was always a respectful kid and began to turn his head away on his own.
Clark went off to college first to pursue journalism. It didn't stop your contact with each other, even when he went off to Metropolis first. You simply told him you’d follow him soon. And you did.
You had your own place in the city, no longer dorming as it was your last year in university. Still, you spent more time in Clark's apartment than on your own. You had a key to his place, welcoming yourself and making yourself at home even when he was at work on the Daily Planet— especially when he was at work as superman.
You’d fussed over wounds you knew would heal at the sight of first light, and he would let you take care of him. Clark knew it calmed you down.
Clark always let you do what you wanted, and would always do as you asked.
And now, he was unzipping his pants.
“Wait,” you say quickly, as his thumbs hooked under the waistband of his briefs. “Are you okay with this?”
Clark's eyebrows pull together, eyes flickering up to you. “You’re the one who asked, and now you’re the one backing out?”
“I just… I don't want to make you uncomfortable if you don’t actually wanna…” you murmur slowly.
“It’s you.” His words are said like it’s normal— like being you was a good enough reason to do anything. In this case— take his pants off. “I don't mind.”
You swallow, a weird rush of sentimental feelings going through you. Then, you nod, steeling yourself. “Show me your weird alien cock.”
“It's not weird,” he grumbles, “You’re lucky I love you.” A moment later, he’s lifting his hips off the couch slightly as he pushes both underwear and pants down his thighs.
Your jaw drops, and you suddenly can’t breathe.
The sight before you— he was right. His cock isn’t weird. If anything, it’s the prettiest dick you’d ever seen.
Maybe it was the mix of him being carefully groomed as well and the fact the man before you was already pretty everywhere else, but you don’t think you’d ever seen a dick as nice as his.
Clark's soft, but he’s still big. His skin is smooth, resting against his pelvis, dormant and asleep. You wondered if he was a grower— if he got bigger than the estimated seven inches you were staring at.
Even his balls were fucking nice to look at. The seam of it— oh my God. You were going insane.
“So?” he questions, breaking the silence and your thoughts. He sounds nervous, “What’s the verdict?”
You lick your lips, taking a deep breath. “You're actually really beautiful, Clark."
He stares at you, and you’re certain it was the last thing he expected you to say. So, you clear your throat.
“I mean,” you start, “I've seen a good amount of cock. Yours is, by far, the best.”
Clark blinks at you, still digesting your words. “… Thanks. I guess.”
“Is it as soft as it looks?” you ask, finally getting a grasp of yourself again. “It looks soft. Like— your skin.”
He pauses for a moment, looking down at himself. Then, he reaches.
You lied. You don’t have a grasp of yourself. Your sanity is gone, thrown out the window at the sight you were witnessing.
Clark, sitting there on the couch, pants pulled down, with his hand wrapped around his cock. He's still flaccid, but he’s running his hand along his dick, trying to get the best answer for your question.
“Just feels like… the rest of me,” he murmurs, frowning as he concentrates. “Nothing really different. You wanna feel?”
You’re a dead woman.
You brought up this topic. At first, it was genuine curiosity. Upon seeing his reactions, you moved onto some lighthearted teasing. It wasn’t supposed to progress to whatever was happening now. In the back of your mind, you’re wondering if he’s doing all of this now just to mess with you like you did with him.
The curious look on his face tells you he’s not even thinking about it.
You should tell him it’s a bad idea. That there’s boundaries in friendships, and even though you’re so comfortable with him, maybe there’s things you shouldn’t be doing.
But your feet are moving, and you’re standing in front of him within a few steps.
“You sure?” you ask, hoping your voice comes out steady.
Clark releases himself, then nods.
You’re leaning forward before you have the chance to allow more rational thoughts to invade your mind. It’s as if your hand wasn’t connected to the rest of your brain, moving before you could even stop yourself– and holy shit your hand is small compared to him. He's warm to the touch, skin smoother than you originally thought.
His cock jumps in your hand, and Clark flinches. The gravity of the situation just dawned upon him, and blood was rushing throughout him, coloring his cheeks and hardening his dick.
“Wait,” he whispers, breath catching in his throat. “I’m sorry— I didn’t— I'm not meaning to—“
“You really are pretty, Clark,” you cut him off, a little mesmerized.
You can feel his eyes on your face, but you’re not looking back at him. You still can’t tear your eyes off the annoyingly pretty sight of his cock. Then again, you should’ve expected it. The rest of him was just as gorgeous.
There's a vein popping on the underside of the shaft, thick and pulsing against your palm. His skin is still smooth despite losing the soft feel of it. And you were shocked— he was a grower. Both length and girth filled out with the rush of blood, and your mind wandered.
His ex was fucking wrong. This man wasn’t above average. He was far from it— this was off the scale. He was Godly.
“I don’t think you’d be able to fit.”
The words slipped out of your mouth softly, mainly spoken to yourself more than him.
Clark's breath hitches. “What are you…”
“Just, theoretically, if we had sex, I don't think you’d fit in with me. You'd probably rip me apart— my hand barely can hold all of you when you’re soft, let alone hard. I don't know if it would even feel good to have you inside of me.”
“Oh my… You really can’t be saying these kinds of things while you’re still holding me,” he groans, head dropping back against the cushions as he shut his eyes.
“I’m not wrong,” you argue. “Logistically speaking, there’s no way this would feel pleasurable for me– you’d tear me in half before I even get to cum.”
He lifts his head, and you look up at him. He's still flushed, but now he looks offended. “If we had sex, I wouldn't just stick it in you. I know it’s bigger than average so I'd make sure you’re prepared first. I'd need to fit at least three fingers in you— comfortably— before either of us could imagine me inside you. Besides that, who says I wouldn’t make you cum at least twice before I even want my dick in you?”
You can’t help the warmth you feel in your nether regions— like a sudden zap that went between your legs to make you feel weak at the knees.
Clark notices. He always does.
He swallows, visibly nervous as a whisper comes from his lips. “Did I make it weird?”
You’re surprised you can even suck in a breath. You shouldn’t be able to breathe. Your autonomic nervous system should be failing, but here you are.
“Only weird if you think it’s weird, Kent,” you murmur.
“You smell different.”
Fuck him, and fuck those super senses of his. You should’ve known better— he could easily spot every single twitch in your body, the change of scent as pheromones exit your body, and the feel of the light tremble of your hand against him.
But despite all of that, a smile comes to your lips.
“Now you’re making it weird,” you tease.
A devastating grin spreads Clark Kent's face. “My apologies. Thought we passed weird when you didn’t take your hand off me,” he hums.
“You want me to?”
The smile falters, and his eyes meet yours. He's reading you. Your face. reactions. Anything he can use to figure out what’s going through your head. You're doing the exact same thing to him.
Finally, he speaks.
“No. Want you closer, actually.”
You don’t fight him when his hands reach for you, landing on your hips. You don’t fight him as he guides you towards him, your knees resting naturally on either side of his thighs.
You’ve released him now, but only in favor of your hands sliding up his chest before finding home on the broad expanse of his shoulders. He's looking up at you, blue eyes swimming with an emotion you see every day— love.
Only now you’re realizing that the simple love you!’s that you’ve been throwing at him meant something else entirely for him.
“There you are,” he murmurs, thumbs rubbing circles into your hipbones. “You only notice me when my dick is out and between us?”
“Thought you didn’t like that word,” you say, a little breathless.
Clark smiles a bit wider, eyes sparkling. “I don’t mind it every once in a while.”
A laugh falls from your lips as you stare down at him, taking in every ounce of affection he was oozing out at you. You want to say something to acknowledge his feelings, but not yet. Not when you’re currently hovering over him, his cock still out and slowly, but surely getting more firm as the seconds pass.
“You gonna show me how you’ll fit?” is what you say instead.
You’re in his bedroom within a blink of your eyes— comfortably beneath him as he hovers over you.
“Sorry. ‘m a little excited,” Clark confesses, breathless as if moving at the speed of light was difficult for him— of course not. It's you. You're the entire reason his heart rate picked up, that his hands were slowly turning clammy, and why he feels like he can’t breathe.
“I can see that. feel it, too,” you grin at him, and a groan pulls from his lips as he shuts his eyes. Still, he doesn’t move away. If anything, he presses closer, slotting himself perfectly between your legs, dick pressed right against your aching core.
“You're lucky I love you,” he sighs.
Clark descends on you, lips meeting yours in what you can only explain as home. He’s warm, always is, but never in a suffocating way. He’s like the first warmth of spring after a long winter.
“Take this off,” he murmurs against your lips, but is already moving to remove your shirt for you.
His hands slide under the fabric leaving goosebumps in his wake, and breaks the kiss for just a moment to pull it completely up and over your head. It’s discarded without another thought, tossed somewhere to the side.
He cups both breasts through your bra, lips trailing from the corner of your lips, down to your jaw, and finding their place on your neck.
“Gosh,” Clark sighs against you, peppering tickling kisses down to your collarbone, “I’ve dreamt about this moment before.”
“Do I live up to your expectations?” you ask, breathless. You arch, pushing your chest further into his palms.
He groans, and if you didn’t know any better, you’d say this entire situation causes him pain. Except you do know better, and he’s in heaven.
“Better,” is all he says before his kisses move even lower.
You’re certain he used his x-ray vision to locate your nipples over the thin padding on your chest. There’s no other way, you think, that he managed to be so precise. In the back of your mind, you wonder if he’s ever used this ability to feed some of his darkest desires.
No, you decide. Your sweet, kind Clark wasn’t like that. Though you really wouldn’t have minded it.
A soft moan slips out of you, cautious and shy. His response? To smile against your chest, and reach beneath you, undoing the clasp of your bra with a single manipulation of his fingers.
“You practice that a lot in college?” you whisper as he tugs the fabric off your chest.
“Mm… Not lots of practice, but enough,” he hums, eyes taking in the sight of you. He looks in awe, unable to believe this was truly happening to him. Soft hands run down your sides, just needing to feel you. “So pretty, sweetheart.”
Your heart flutters in your chest, and you can feel your skin warming. Just one compliment, one silly little nickname, and you’re melting for him. Maybe he’s got you wrapped around his finger more than you realized it.
“Want this gone,” you tell him, tugging on the hem of his t-shirt in attempts to gain some form of control over the situation.
Clark chuckles, and gives you a small nod. “Yes, ma’am.”
He doesn’t give you any time to appreciate the beauty of him— the sculpted muscles that lay beneath the slightly baggy clothes he wears in hopes it hides his superhuman physique. Usually, he keeps his shoulders pulled in, a slight slouch to his posture, but in this moment he’d never looked larger. Confident. Yours.
Your sweatpants and panties were being removed from you, joining whatever corner your shirt was thrown into.
Without hesitation, Clark fit himself right between your legs. His hands wrapped around your knees, moving you to hook over his shoulders comfortably. Of course, not without him pressing a sweet kiss to the inside of your thigh.
“You smell so good,” he whispers against your skin, lips trailing higher and higher up your leg until he was hovering right above where you needed him most. “Goodness… Already dripping for me and I haven’t even done anything.”
“You gonna hurry up and do something, Clark?” you ask, impatience pulling from you without realizing it.
“Easy there.” His eyes lock onto yours from below, a sparkle on them. “Gotta make sure you’re ready for me, baby.”
Before more whines of complaints can form in your head, his flattened tongue licks a slow strip between your folds, parting them and giving him perfect access to your aching clit.
A moan vibrates through your core, unabashed and utterly delighted.
“Tastes so good, too. Could stay here all day,” he mutters against you, breathing hot and heavy.
“Clark—“
“Yeah, yeah. I know,” he huffs. “One day.”
Clark didn’t verbalize the rest of his disappointment. Honestly, with the way he thoroughly laps at your core, you might have to reconsider your decision.
It’s as if he had been dying of thirst for his entire life. He dips his tongue in and out of your core, groaning in absolute joy, before moving to suck on the sensitive little nub that’s begging for his attention. You can’t help it when your legs start trembling around his head, threatening to close and trap him there. In the back of your mind, you realized that he wouldn’t care if you did. He’s able to hold his breath for over an hour, after all.
The sensations are all too much for you to handle, sparks flying behind your eyes as Clark seems to struggle to pull himself away from you. Eventually, he gives in. Tonight mercy is granted to you as you stop tugging on his hair to begin pushing him away instead. From the way his eyes are blown out, nearly every part of his eyes covered with black instead of blue, you know that you’ll find yourself back in this position another day.
But not right now.
Right now, you need him– all of him–
“Slow down,” he mutters to you as you yank him up your body. Clark rests beside you now, free hand helping him prop his head up to give himself a good view of your entire body. “Haven’t even started to stretch you out.”
You whine, heart still pounding from being brought to heaven and pulled back down to Earth. “Clark, you need to hurry up.”
“We have all the time in the world,” he coos at you in an attempt to try and soothe you. It doesn’t work. What does work is his fingers gliding up your thighs, reaching the warmth between your legs, and pushing in.
You always knew Clark’s hands were big. It matched the rest of him– long, slender fingers that seemed like they could whole the entire world with ease. If you verbalized any of this to him, he would tell you that he was doing exactly that– holding his world safely in his hands.
The introduction of a second finger has you squirming beneath him.
“You’re so soft,” he says, pressing a soft kiss to your forehead– a stark contrast from the filthy way his fingers were spreading you open with a scissoring motion. “So wet for me, aren’t you? Gosh… Can you hear yourself?”
Of course you can. The squelching noise coming from your lower half was hard to ignore, after all.
You coated his fingers in your essence, and Clark was certain you were seeping into his skin, marking him as yours. You wouldn’t be able to smell yourself on him, but he would still be able to smell you on his skin for days to come.
His digits curled slowly within you, rubbing against that extra soft, spongy part inside of you. His eyebrows shot up in amusement as you gasped out his name, hips lifting slightly off the bed.
“Right here, honey?” The low baritone, gravely whisper of his voice in your ear sent shivers down your spine. He was invading your every being, just as you’d done to him for years on end.
The stretch of his ring finger made the air in your throat catch.
“Easy,” he orders, clicking his tongue softly in disapproval.
“It’s— fuck, that’s… A lot,” you manage to stutter out, eyes screwing shut.
“If you think this is a lot, how can you ever imagine taking me?” he asks, almost teasingly.
A shaky breath exits your lips. “You’re— you’re enjoying this.”
“And you’re not?” Clark shoots right back at you before plunging all of three digits into your fluttering hole— right down to his knuckles.
Your best friend doesn’t wait for your answer. Instead, he begins to work into you, the length of his fingers slowly massaging in and out of you. You twitch beneath him, mouth falling open in a wordless moan.
Try as he might, his actions were only making you clamp down tighter around him. You were trying to suck him in, keep him deeper within you.
With one more slight curl, you were coming undone. Your fingernails digs crescent marks into his wrist, trembling as you attempt to keep your sanity intact.
Slowly, his fingers exit you.
“Mm… I don’t think you can take me tonight,” he mutters, more to himself than you. You nearly missed his words, all of your body paying attention to the way his fingers moved upwards to lazily circle at your clit. He presses a kiss to your temple, “Next time, hm?”
Your heart nearly stops in your chest as you look up at him, wide eyed and pleading.
“What?” you ask, voice hoarse and dry from the moans you gave him. “Clark— No, need you—“
“I’ll just hurt you if we do it today.” He shakes his head. “Need to spend more time. One night of prep isn’t enough—“
“What if I want it to hurt?” you cut him off, head spinning. Clark looks at you, eyebrows pulled together in confusion. “Just need you in me— need you to stuff me full. Need it so bad, Clarkie.”
He’s not convinced yet. You know it for a fact. He’s still thinking too rationally for your liking. But he’s pulled his hand away from your legs, resting it on top of your stomach instead— if he was truly unaffected by your words, he would’ve continued his ministrations. No, he was trying to keep his control by limiting his touch.
You couldn’t have that.
Your hand finds his cock again, eyes still locked with his. His lips part to suck in a tight breath of air as you slowly palm at him. You run your hand up and down his length slowly, then reach the tip. To your delight, he’s leaking.
“Look, baby. He’s crying for me,” you whisper to him, swiping your finger across the head of his dick, picking up a bead of precum in the process.
For the first time that night, Clark’s gaze breaks away from your eyes. His eyes drop down to your lips, watching as your fingers enter your mouth to lick off his arousal. His breathing picks up, ever so slightly.
You release your fingers with a pop, then move to rest them on his lips. He opens his mouth without any instruction or order, tongue wrapping around your fingers and licking, sending a new wave of excitement crashing through your body.
“So big, so hard for me,” you sigh, almost pouting at him, “And you’re not gonna fill me up?”
Clark moans around your fingers like it pains him, like he’s trying his best to hold onto the restraint that you’re chipping away from him.
“You know I’m on birth control,” you tell him, pulling your fingers from his lips. He moves forward slightly, as if trying to chase them. Once again, his eyes meet yours. “You wanna indulge me in some more research? This one would be an experiment, really.”
He swallows. “What kind of experiment?” His voice is broken.
You smile sweetly at him, resting your hand against his chest. You can feel his heart beating rapidly under your touch. He’s waiting, on the edge of whatever sanity he has left.
Finally, you whisper, “I want to see if Kal-El’s sperm can beat the efficacy of my daily pill.”
Within a breath, Clark pulls you to the cusp of his bed. Your legs only dangle off the edge of the bed for a few seconds before he pulls you to rest them against his hips. He shadows you, cock resting on your tummy as he leans over and presses a hard kiss to your lips. His teeth catch and tug, demanding entrance that you happily give him.
His hands rest on the inside of your thighs, spreading you open for him as he pulls back his hips slightly. The length of his cock drags against your skin, leaving a trail of burning desire and want. He coats himself in your slick, depositing a moan into your throat as he does.
The tip of his cock is right at your entrance, parting your puffy folds, and stops. You’re about to whine against his mouth, grab at his shoulders or wrap your legs around him, but he doesn’t leave you waiting for long.
Clark Kent is a fucking liar.
Three fingers and two orgasms was not enough to prepare you, prepare anyone, if you were being honest. Even with the fact you were quite literally dripping for him, it still wasn’t enough to ensure a smooth entry. Then again, he did warn you. This was partly your fault for egging him on until he couldn’t stop himself anymore.
Your lips still against his, eyebrows stitched together as you try to adjust to the foreign body entering you. Clark notices– of course he does– the way your muscles lock beneath him. Your lungs stop pulling in air, and you’re gripping his forearms so hard he actually registers a small nip of pain.
His voice cuts through the cloud in your mind. “Breathe, honey.” Clark showers you with kisses– your nose, cheeks, eyes, neck– anywhere he could reach. “I know it’s big, baby, I’m so sorry.”
With his words snapping you out of it, you suck in a greedy gulp of air as you open your eyes to look at him. “F… Fuck, Clark,” you gasp out.
“I know, I know,” he reiterates to you, patient and so understanding despite the fact you were the one that begged him for this. “Try to relax for me, okay?” Another kiss gets pressed to your eyes, his lips catching a stray, salty tear that slipped out. Your heart skips as you watch him swipe his tongue across his bottom lip, tasting your tears.
“You’re so big– God,” you say, voice cracking.
“Not God,” he corrects with a chuckle, “But yes.”
“Fuck you,” you whine, unsure how he can find this situation funny. Still, the way he lets out another small laugh above you does ease your body just a little bit– probably from the familiarity.
You focus on Clark, deciding that he will be the best way to distract yourself from his cock, as ironic as it may sound.
The way there’s a slight crinkle around his eyes as he smiles at you. If you focus, you can see yourself in the reflection of his eyes. There you lay beneath him, skin flushed with a light layer of sweat all over you, hair touselled and mussed up, yet he still holds a love for you that you don’t think you’re worthy of carrying.
His skin is warm under your touch, always is, but goosebumps are left behind wherever you touch. His body is reacting to you, showing you that the littlest things you do leaves a mark on him both physically, emotionally, and mentally.
How he touches you with extreme care, though you know it’s easy for him to break even the toughest of metals in his hand without even breaking a sweat. He’s always treated you delicately. Always a gentleman, opening every single door without complaint or annoyance, pulling out your chair whenever you have a meal together, and holding your hair back whenever you end up drinking a little too much. So kind, thoughtful, and nice. You wonder how much you’d have to push him to fully break you.
It’s only when your mind trails back into its sinful desires do you register his hips fully flushed against yours, his length sheathed within you.
Clark’s pulling in shaky breaths, hands resting on your hips with his thumbs rubbing circles into your skin. His forehead rests against yours as he closes his eyes, trying to get a grasp on his bearings once more.
“I… Sweetheart,” he grunts. “You’re still so tight around me.”
As if his words were to be a reminder of your situation, your walls flutter around him, sending pleasure through both of your bodies.
“Move,” you tell him, breathy. “Please–”
“Hang on,” he cuts you off, shaking his head. “I’m not paused right now for you. I might–” Clark cuts himself off, biting the inside of his cheek. For a moment, you thought he might curse aloud for the first time in years. Instead, he swallows thickly. “I might lose it right away if I don’t give myself a break right now.”
Pride swells in your chest. “Superman is a minuteman?” you tease softly.
“Hey–”
A shared moan stops whatever rant he was about to go on, thanks to your hips rolling against his. And you can feel it, how his dick twitches deep inside of you, already so close to the edge even though he just got there. You can also feel him pressing up right against your cervix.
His fingers dig into your hipbone– not hard enough to bruise, but hard enough to warn. Clark pulls back, looming over you as he takes in a deep breath.
“You’re playing dirty,” he accuses, voice as tight as how he holds his jaw.
“So what if you cum fast?” you grin at him, hands moving to rest on his abdomen. “Don’t tell me Superman can’t go a couple rounds.”
His eye twitches, and you know you’ve hit him somewhere personal. Then again, baiting Clark Kent was always your favorite pastime.
“Of course I can,” Clark says with a tone you know all too well– one that lets you know he’s about to prove you wrong.
His hips pull back, cock dragging out of you so painfully slow until just the tip of him is left within you. You mistakenly believe that he’s going to slam back into you without any warning. He doesn’t.
Clark pushes back inside of you slowly, giving you the chance to properly feel the ridge of his tip as it meets the shaft of his dick. You can feel a pulsing vein on the underside, matching the rapid beat of his heart. You can feel him separating your gummy walls with each new inch of him, forcing you to accommodate his size. And you can feel the bulge in your lower abdomen– him– deep inside of you.
“Shit,” you gasp out, but you don’t have time for anymore words. He’s pulling out once again before thrusting back into you, setting an easy, comfortable pace. Despite it, you can’t even begin to form any thoughts. He’s splitting you apart, filling you in ways that you’ve never felt before.
“That’s it,” Clark chuckles from above you. You catch a lazy, nearly fucked out smile paint his face as he watches you. “You know, I think I like you better when you’re not talking.”
You whimper in response, unable to properly respond to him.
He hums, leaning back down to kiss you, his movements never stopping. “I got you, baby. Don’t worry– You’re so pretty like this.”
Clark swallows all your moans and whines like he’s desperate to have them. All you can feel is him– his hands running up and down your body to map you, the feel of his cock piercing in and out of you, his tongue brushing against yours, his muscles rippling and flexing whenever your hands find somewhere new to hold onto.
“You look so good like this. So perfect, so beautiful— gosh, you look so pretty with me inside you,” he murmurs against your lips, voice strained ever so slightly. He moans out your name when your walls flutter around him again, giving him one brief warning. His hips snap harder into yours, efforts renewed as he urges you to your doom. “C’mon, baby. Give it to me– need you to make a mess all over me.”
As one final push, Clark presses a hand onto your stomach, snapping the last bit of pressure within you. “God– Clark!” you cry out, eyes rolling to the back of your head as you begin to tremble beneath him.
All the while, he never lets up. If anything, the pace is faster, chasing your high with everything he has– prolonging your pleasure for as long as possible.
One more time, your name falls from his lips, this time strangled and needy before you feel a warmth deep inside of you. He’s coated you from the inside, both of your sticky juices mixing together into one substance as he lodges his cock deep inside of you, poking at your cervix.
Clark collapses over you, careful to keep most of his weight on his forearms. Still, his chest is pressed against yours, allowing you to feel the thumping beneath his skin.
He collects himself faster than you, lips trailing all over your neck and collarbones as his cock jumps within you, hard once more. When you look at him with disbelief, he gives you a stupid grin that you nearly melt for.
“What’s with that look?” he asks, nipping at your lips. “You only have yourself to blame for this.”
“I didn’t do anything just now.” You frown at him, though not entirely upset.
“No,” he agreed, “But you did challenge me to put a baby in you. I’m feeling competitive tonight.”
You almost wish you never said those words out loud, never teased or poked him until he broke. Almost.
Warm water sloshes around you as Clark lowers himself into the bath behind you. He instantly engulfs you with his size, his body granting you more heat than the tub you both sit in together. You lean back against his chest, closing your eyes.
Exhaustion ran deep in your bones. You don’t fight against Clark as he begins to scrub your skin with soap, cleaning off the sweat and stickiness that accumulated during your time together. Still, you know he can’t get rid of the markings he left behind.
You caught a glimpse of yourself in the mirror when Clark carried you into his bathroom earlier. Purple, manmade flowers had grown across your skin, effectively ensuring you’d be wearing high neck clothing on days you didn’t feel like doing your makeup.
You should be mad. You should scold him for losing control, but frankly… you don’t really care, especially not when he lowers his head slightly to press a delicate kiss to your shoulder.
“How do you feel?” he murmurs against your skin.
“Good,” you sigh, content. “Might be sore tomorrow, thanks to someone.”
“You asked for it,” he reminds you, and you can feel him smile against your skin.
“Yeah, yeah,” you dismiss, but you’re smiling too.
Tomorrow, you both will have a discussion. A long talk on where you both stand in each other's lives, and how to ensure your relationship with each other won’t end up in flames. But all of that is for your future self to deal with.
Right now, you’ll revel in his touch, allow him to wrap his arms around you, and fall asleep to the sound of his breathing.
