Preheat sucked almost as much as heat itself. It was sweaty and awkward and empty. Miserable. It was miserable, and that was all there was to it.
Bruce always struggled in the past, but at the very least he’d had medications to tide him through the worst of it. Now he was no longer so lucky. He’d had the misfortune of meeting the alpha he was certain was his true mate, something so exceedingly rare that he just had to be unlucky enough to have one. His body, knowing there was a truly biocompatible option, had been in overdrive the entire year since and he was quickly losing patience with the mess of hormones and instincts. Even more unlucky, the alpha just happened to be Superman.
The common consensus, he knew, was that anyone would be lucky to have Superman. Arguably the world’s most powerful alpha. Compassionate, warm, unbearably attractive. He wasn’t blind, and his body screaming at him made it clear that there would be no getting around his cycles or his rapidly fogging brain. Bruce just couldn’t get past the part of him that still registered the man as a high pressure valve just waiting to burst.
Not helping the issue was the device the alpha himself had given him, allowing him to peer into other universes. In times like this, when he ran out of things to do in his own world, he would occasionally take a look. Just to see what he might be going through in another life. He’d seen enough universes where Kal snapped, and it was exceedingly helpful in preventing him from giving into his urges and finally allowing his alpha into his nest.
Bruce gave his head a hard shake. His alpha? Thinking like that was dangerous. He needed to hurry it up to remind himself why they couldn’t belong to each other.
Viewing it was much the same as always. The vast majority of the universes contained good, kind versions of the alpha. Supermen who continued operating with deep care and concern for others, and Batmen operating at their sides. He pushed through those quickly, pretending he didn’t notice how much his pupils had dilated in the reflection of the dark screen while he waited for the next to load.
Finally the familiar sight of an angry Kal greeted him, white cape flowing behind a black suit. He drew in a shuddering breath as he watched, heat and fear crawling up his spine in equal measure. This version of Kal was never quite enough to push him away, though. Never enough to stop the intense feelings of want and need and alphaalphaalphamine. He pieced together what happened well enough. A fellow hero he hadn’t met yet in his own universe was killed, and Kal finally snapped. Finally took over. His version of Bruce operated right by his side, a member of a team called the Justice Lords. He tried not to wonder if they were mates. He never lingered there long.
He took one last look, his heart squeezing when he heard the alternate Kal refer to another version of him as a busy little bat. He shuddered and forced himself to move on. The next one to pop up was also angry, leading an army against Bruce. He wasn’t sure he was able to stomach that today. He caught sight of Kal about to land a fatal hit and immediately changed, not waiting to see where it loaded next while grabbing the trashcan so he could vomit.
There was nothing he could do about it. That’s not my Kal. Not my Clark, not my Alpha, he rationalized and placed the trash can down, walking away to brush his teeth.
He could hear the video feed playing from the decontamination area of the cave, soft gusts of wind and the rustle of long grass against each other, the distant barking of a dog. Kal, Clark, he said he grew up on a farm, Bruce reminded himself. Maybe he’d stumbled across the feed of an older Clark who’d isolated on the farm he grew up on, stark white coloring the sides of hair that had been jetblack in his youth. That was always soothing, despite the underlying sadness and irritation he could feel emanating off of that version of Clark.
Bruce immediately froze and spit when he heard a language he’d only encountered spilling from Kal’s lips, one man and one woman engaged in hushed conversation. Kryptonian? Kryptonese? Bruce still wasn’t certain of the correct word, and he hadn’t pushed for clarification. He was far from fluent, but it was beautiful to hear spoken.
Is this the aftermath of one of his worlds? Did he conquer and rebuild Krypton?
His brows knit as he walked back over, a reddish sky and vibrant purple grass covering the monitor in a vivid, alien landscape. Not earth, then. This actually was Krypton. Gorgeous, despite how alien it was.
Bruce adjusted the view so he could see the speakers and immediately froze again. Parents. Those were Kal’s biological parents. They stood in stark contrast to the landscape, with beautiful jet black hair and shimmering, unearthly blue eyes. He wasn’t sure if Kal favored his mother or his father more, when he imagined the one from his own world. He was just as beautiful as his parents, with his father’s well defined jaw and the delicateness of his mother’s features with her loose, flowing curls. All three of them were stunning in their own right, and he wondered if the Els were just ridiculously attractive, or if all Kryptonians were blessed with good looks.
While he was contemplating this he looked at each of Kal’s parents just a little bit closer, tilting his head at the wounds that were just barely dressed on Jor-El’s face. He could see concern painting his features in the same way it shaped Kal’s face when trying to puzzle something out. There was clearly something wrong.
His mother doesn’t look pregnant, Bruce thought, shifting the view again. But it’s clear that Krypton is still dying. Where are you, Kal-El?
Apparently Jor-El seemed to have the same thought and straightened up with wide eyes, calling out for his son. Bruce held his breath and chewed at the inside of his lower lip, watching closely as a young, distraught child rushed over, a large, messy dog by his side.
Krypto, his mind supplied him.
He looked carefully, a low whine escaping him when he froze the playback at the mention of the name Kal. There he was, barely more than ten years old, and the absolute cutest child he’d seen in his entire life.
Kal’s little brows were furrowed and his mouth was set in a pensive frown, delicate features painted with concern and sadness. His eyes were big and blue, hair a mess from running through the field with his dog, and another pained whine escaped him at the thought. Kal knew there was something wrong despite how painfully small he was.
Bruce couldn’t decide if this was more or less cruel, this Kal understanding the loss he was facing or the Kal he knew still wrestling with the fact that he would never understand his heritage.
He hesitated and hit play, the small boy darting into his parents arms and melting into an embrace. Bruce whined again, changed the angle so he could look at Kal, and felt his resolve shatter.
That baby should be his. That was his little boy. His pup. He needed that baby in his arms, and he needed it now.
Bruce backed the footage up to get a closer view of the boy’s face and felt another ragged whimper, his insides feeling pitifully empty. Pup! Pup! Pup! Mine! His thoughts screamed, forcing him into motion.
He would never be able to make it to that universe, but he could have a baby who looked just like that and he knew exactly who to call for. Bruce ran for the stairs and took them two at a time, glancing back to see that sweet little face one last time before entering the manor.
Running through the halls, now in active heat, was a surefire way to be scolded by Alfred, and he didn’t have time to wait. He needed to get pregnant, and he needed to get pregnant nine months ago. He just had to hope he wouldn’t be noticed.
Sharp whines kept escaping him as he ran, that haunted expression reflecting behind his eyes. He skidded to a sharp halt when Alfred stepped in front of him, embarrassed by how loudly he was whimpering, but ultimately deciding he didn’t care. He needed.
“Alfred,” Bruce said, trying desperately to remain polite in the face of his rapidly escalating heat. “Can I help you with something?”
Alfred’s eyes narrowed, but he took a small step back. He must look as horrible as he felt, but embarrassment was fleeting. He had a goal, he had a desire he needed filled. If only he could escape this conversation without earning himself anger. “Master Bruce,” he said, arms folded, “I was coming to check on you down in that cave of yours.”
He let out a tense laugh, mind drifting back to the image that would display the next time the computer was taken out of sleep mode. Alfred was going to look. Let him, the voice in his mind said, and he found no reason to disagree. That was his baby. There was no shame.
“Well,” Bruce said, fighting back a soft whine, “as you can see, I’m totally fine.”
“Totally,” Alfred repeated, looking particularly unimpressed. The man sighed and gave his head a shake, stepping aside. “Call him.”
“You don’t know that I’m going to-”
“You are, and you need to, and I won’t make you talk about it, but I am not sitting through another one of these restless heats where you sprint through the halls like a madman,” Alfred told him. They’d never ventured into this before. Alfred knew he had toys. Hell, Alfred was the one who got them for him. He’d never invited anyone into his bed before and they’d never discussed it beyond Bruce telling him to never, ever hire an alpha for relief, no matter how bad it got. Luck and patience didn’t seem to be on his side today.
He groaned and shook his head, running a hand through his hair in an attempt to push it out of his face. By now he knew he was likely sporting a bright blush, his trembling visible, and his slick and hormones able to be picked up even by Alfred’s beta senses. “Fine,” Bruce huffed. “You caught me. I’m calling him.”
Alfred raised an eyebrow, head tilted. “Does this change of heart have anything to do with that charming little pup you were looking at down there?”
In his haste he forgot that Alfred monitored him when he was so close to heat, especially with suppressants no longer offering any relief. He forgot that every single action, probably starting with his first pained whine, was watched through a surveillance camera and was likely what prompted Alfred to come check on him in the first place.
“Yes,” he admitted, eyes still down. “Yes. That’s… it’s… him. Him, on Krypton, and I need my baby to look like that-! Alfred, I need-”
“Master Wayne…”
Bruce let out a pathetic whine and slouched further, eyes welling with tears. “I saw him and I- I can't believe I'm- fu- I… need my pup!”
“I know,” Alfred reassured and urged him closer. A warm hand settled on his shoulder, but it felt wrong. Beta calm attempted to reach him, but his mind was already slipping further and further into a haze. “Your mother was the same when she found your father’s baby pictures.”
Another sharp whimper escaped him as he squirmed, skin crawling as heat and want licked up his spine. “I need my pup,” Bruce whined, pressing a hand against his stomach. “I need my pup, and I need it to look like Alpha…”
If Alfred was surprised, he didn’t show it. He nodded and pulled Bruce in closer, lightly wiped at the tears under his eyes with a soft, white cloth, and offered a very small smile. “Of course,” he whispered and tucked the cloth away. “Call for me if you need anything.”
“Not mad?” Bruce asked, finally daring to look back up.
“No, my boy,” Alfred reassured. “Your parents… They’d approve, too.”
Bruce didn’t know how to address that, either. He just nodded a little bit and stepped away, thankfully almost to his room before glancing back over.
“Be safe!” Alfred said, a little bit louder, jarring him into a small nod.
His pseudo-father figure may approve of Superman being the sire of his pups, but Kal might be on thin ice. Their last encounter wasn't exactly on good terms, but they weren't fighting. More arguing over whether or not they were going to do anything about their situation. Maybe Alfred was just worried Bruce was biting off more than he could chew. Whatever the reason, he couldn’t bring himself to waste more time.
The bedroom door shut heavily behind him. There wasn’t going back now. He glanced around at his nest, horrendously messy and incorrect, another sharp whine escaping him. Bruce gave his head a hard shake and opened the door to the balcony, but couldn’t stop himself from feeling irritated at his nest. It didn’t feel complete, despite the fact that it took up the vast majority of his bedroom, with multiple soft mattresses and cushions on the ground under piles of soft fabrics and heavy blankets. It smelled too much like him, not enough like Alpha.
Bruce couldn’t even pay attention to the sharp whines that were escaping him as he arranged and rearranged the pillows and blankets, desperation clawing at him. It has to be right before I show Alpha, he thought, digging his hands into another pile and freezing in place when he heard a stifled gasp.
There, hovering lightly at his balcony, was Kal. Sans suit, in soft flannel pants and a Tshirt, flushed with rut, gaping at him. “No!” Bruce yelped, tears already streaming down his face again. “No, it’s wrong, it’s not ready for you yet!” He hadn’t even realized he’d moved closer until his hands hit uselessly against a sturdy chest. “You weren’t supposed to see it yet you big, dumb alpha!”
“B! Bat!” Clark said, catching his wrists and eliciting a growl. “You were calling for me!”
Bruce drew in shaky breaths, mind fogging further with the scent of Alpha right under his nose. Still, he had to keep it together. He hadn’t even realized he’d been yelling for Kal, or Clark, or whatever other ridiculous name he’d adopted that day, but he actually… believed it. Alpha was nothing if not considerate. He wouldn’t take advantage, he’d been suffering through ruts alone in that little apartment of his. Good alpha, smart alpha, Bruce’s thoughts seemed to purr, already urging him to turn into putty in those large, warm hands.
“Cape,” he huffed, after looking him over again. “Where’s your cape, you idiot?!” Bruce let out a loud groan and slumped forward again, smacking lightly at his chest. “I want it!”
Tracking the speed of motion was actually impossible. Before Bruce even felt the lack of another warm body the alpha was back, draping a thick, red cape over him. Not a spare! Smells like Alpha, he thought, trying and failing to hold back a loud purr.
He nuzzled against the fabric, eyes darting up for a second before looking back down. Kal looked… hopeful, if not a little bit sad. “Is there anything else I can do for you, Bruce?” He asked, tone soft. “You have to let me know now because if I-... if I stay, I'm going to go out of my mind and-”
“I need a baby,” Bruce said without thinking, immediately feeling his face grow hotter. “I mean I need you to put a baby in me!” A humiliated whine escaped him. “I need- I want-”
“Woah!”
“Please, please, just give me a baby and then get the fuck out of my life!”
Kal stepped back onto the balcony and drew in a deep breath, brows furrowed and lips set in the same pensive frown he'd seen that morning. Another pathetic whine escaped his throat when he attempted to step forward and tripped, caught in a pair of warm arms before the alpha was back in open air. He let out another pitiful whine, falling into a pile of cushions and blankets as tears welled in his eyes.
“Why won't you just fucking pup me already?!” Bruce asked in a sob, rolling onto his side and curling tight around the feeling of emptiness deep in his guts. “Just fucking cum and go, that's all you alphas are good for, anyway!”
Another broken sound escaped him when he heard a soft huff of amusement. This is serious, you idiot!!
“Bruce. Bat,” Kal said, still floating outside. Probably an attempt to avoid breathing in pheromones.
Does he really think I'm that disgusting?! A choked sob escaped him at the idea of it. Stupid Alpha lied about feeling the same, stupid Alpha isn't actually my mate! The blood tests said, but did he manipulate it somehow? Stupid, stupid-
“We talked about this, you told me you don't… fuck, smells good…”
Bruce perked up a little bit at the aside, wiping furiously at his eyes and looking up at Alpha again.
“Bruce, you told me you don't care about our biocompatibility, because you don't want a mate,” Clark told him with a tiny nod. Bruce was certain he could see his pupils dilate, could hear his breathing getting heavier. “What changed your mind?”
“You!”
There was a moment of hesitation and a small nod. “I didn't think I pressured you, B…”
Idiot! His thoughts screamed, but he held them in. Good omegas didn't get pupped. He could be good.
“You didn't,” he hissed, reaching a hand out. “Not you you, but that… that thing you gave me.”
Kal moved closer, Bruce's heart fluttering in anticipation. He was wearing that thoughtful expression again, the ache in him intensifying. He could only imagine their pup and its beautiful little face.
“The, uh, the… the projector,” Kal said, lamely.
Bruce nodded, holding the cape tighter around himself. “Yeah, I saw… I saw…” He drew in a shaky breath, but unintentionally took in more alpha rut pheromones as a consequence. “I saw a version of Krypton where you lived with your parents, I… I couldn't understand what they were saying, but I think Krypton was dying and- fuck- and then you showed up and you were so small!”
It was humiliating when his voice broke off in a sob, frustration and want and sadness fighting the heat. He hated all of this needing.
“Kal, you were so beautiful, our pups will be so beautiful, they'll look like you!” He sobbed, drawing in ragged breaths. “I need a pup, I need your pup, I need my pup, I need it to look like you!”
Finally a warm hand settled on his back, Kal seeming to get with the program as a low, comforting sound escaped him. Not quite a croon, but deep and rich all the same. “Oh, Bat,” Kal breathed, pushing his hair back with a light touch. “Is that really what you want?”
Bruce nodded frantically and forced himself to sit up, throwing his arms around him. “Yes! Yes it's what I want, you idiot!” He cried, melting into the warm body. “Stupid, good for nothing Alpha, of course it's what I want!”
“Will you-” Kal cut himself off when Bruce gave him a teary eyed glare. “Yes, Bruce, I'll give you what you want,” he soothed, rubbing gentle circles against his back. “I'll give you what you want, I promise.”
He rested his head on the alpha's shoulder and closed his eyes, taking a moment just to breathe in his scent. Heat wasn't fully set in yet, but his mate being there wasn't making it any easier to keep his head clear. “What were you gonna ask?” Bruce muttered, dragging him down onto the nest. “Will I what?”
Those big, glassy eyes locked on him, warm hands laying him down fully and tucking the cape around him. Bruce could feel the tremors, the restraint displayed despite the rut clearly screaming at him to fuck and breed and take. Good alpha, he thought again, heart aching with affection. Perfect alpha, so good to me.
“Will you… tell me about them sometime?” Kal asked, giving him a tight smile. Bruce could smell rutwantminemineminetake and afraidafraidafraidmateplease coming off in equal measure, a lick of sadness in there somewhere.
“Beautiful, Kal,” he whispered, “your parents were beautiful, just like you. Just like our pup will be.” Bruce rolled on to his back and gave him gentle tugs, squirming until Clark settled between his legs. “You have your father's jaw, and your mother's loose curls and you're so… so beautiful… beautiful, Alpha…”
Bruce reached up to cup the alpha's face, gently wiping away his tears. He didn't realize until then just how he smelled, his own softwantheat and matematematecalmplease. Kal's restraint was remarkable. Despite his shaking and the tears in his dilated eyes, he was acting as a perfect gentleman. A perfect alpha, indeed.
“You want a pup?” Clark finally asked him again, leaning down just a little bit.
He took a second to look Kal over and saw nothing he didn't like. He smelled incredible. Physically, nothing was lacking. Large and strong and warm and tender. When his eyes inevitably traveled lower he felt himself shudder and draw in a gulping breath, a large erection already straining the front of their pants. Need that! Now! Now, now, now, now, now! Take now! his instincts screamed. Bruce was inclined to agree with them.
“I feel so empty, Alpha,” he whined, pulling one of their hands to rest on his stomach. There was no swell there yet, but with a little effort he could make it happen. “Pup! Pup now!”
Surprisingly soft fingertips slipped under the bottom of his shirt, resting on his bare skin. A soft moan escaped him, hips canting up slightly just to chase the light contact. Just give it to me already, you idiot! A frustrated growl escaped at the thought, impatience and heat licking along every single nerve in his body.
“Don't need to growl,” Clark whispered and leaned down, nosing along his jaw. “I'd give you anything. Everything.”
He heard a shaky inhale followed by a soft moan, heavy rut scent filling the air and mixing with his own heat. Nobody had ever scented him this way. He’d never invited anyone to bed let alone in his nest, and he growled at anyone who even attempted it. Alpha scent was never appealing, but their biocompatibility paired with the mating cycle was going to drive him wild. “Alpha,” he hissed, soft kisses pressing against the side of his neck. “Alpha, please!”
Kal made a soft hushing sound against his skin and shifted the both of them to be more central in the nest, but was soon tensing and digging his fingers into the material. A frustrated, embarrassed whine escaped him when one of those hands came up with a toy, thick and heavy, hidden away in an easy to access spot, yet unused in this heat.
Bruce growled when Clark sat up to inspect it and snatched it away, beyond embarrassed at exactly what toy was found. It was red and blue marbled, just over eight inches, and thick with an inflatable knot. He was fairly certain there was a vibration setting, but he'd never used it outside of heat. Most embarrassing was the crest of the House of El, just a little bit not right, emblazoned in gold on the base. A novelty toy Alfred gave him in protest of his decline to actually call the man the knock off toy was inspired by. He'd never admit that it was his favorite.
“That's not yours,” he hissed, face flushed outside of only heat.
Kal only tilted his head at it, an amused smile on his lips. “Well, it's got my shield on it, doesn't it?”
Bruce growled again and smacked at his disappointingly still clothed chest with the side of his fist, ignoring the dull ache it was leaving in his hands. Stupid Alpha and his stupid, cute smile! Stupid Alpha, too sturdy for his own good! His fault! This whole thing is his fault! Him and his stupid genes!
Another low rumble washed over him, a scalding hot hand resting over his lower stomach. “But you're right, it's not mine. It's a little… small.”
“Small?!” Bruce's eyes immediately went down to the tented fabric. “It's the biggest toy I have!”
Those deep blue eyes glinted when they locked in his again, pupils contracting minutely. It felt… predatory. Bruce felt his skin prickle, letting out another whimper.
“Have you used it?”
There was no way to escape that piercing gaze. Stupid, his mind screamed, stupid omega keeping your stupid toys in your stupid nest so you can pretend it's Alpha. Kal's gonna leave, it's what you deserve!
“Yes,” he admitted and looked away, tipping his head to expose his neck. “My favorite,” Bruce muttered.
Stay, stay, stay, he repeated in his thoughts, hoping desperately that his submission would be enough to convince the alpha not to give up on him.
A pitiful sound escaped his throat when there was increased pressure from the hand over his womb, gentle and warm. Heat flickered across each nerve in his body, tears forming in his eyes again. “Don't go… ‘m sorry…”
“Shhhh, Bat,” Kal whispered, leaning forward to wipe his tears with his other hand. “I can’t leave now. I promised you a pup.”
Another pitiful whimper, the tears welling up faster. He couldn’t even tell if his tears were from frustration or arousal, a growl edging its way back out of him. “Then why haven’t you given me one?!” Bruce pushed at their shoulders and squirmed, the hand on his stomach continuing to apply gentle pressure. “You’re wasting time!”
“Bruce, I-”
“Doesn’t your knot work?! Stupid Alpha, all you want is-”
“Bruce-”
“-until it’s time to actually fu-”
“Stop!”
“-and then all of a sudden you don’t even know how to use it anymore!” Bruce growled, smacking at him again with one hand and fighting with the tie at the front of their flannel pants with the other. “Stupid Alpha, you can’t even-”
“Stop testing me!” Kal yelled, more like growled, the hand that was so carefully wiping away his tears gripping his wrist to prevent him from undoing the tie.
Bruce could feel and smell his own fear, but it only heightened the arousal. He needed. He let out a sharp sound when he caught sight of long, sharp teeth that finally finished descending, Kal worrying at his bottom lip and barely stifling the growl rumbling in his chest.
Stop teasing a rutting Alpha, you idiot, his hazed mind supplied, fighting with instincts that barely made sense anymore. He wanted simultaneously to run and be caught, to be alone and be pinned, to be empty and filled. A rough sob escaped him, heat flickering up higher and higher until the sick scent of his own slick hit him again, the mark of a clearly imbalanced omega. Miserable and needy and without any of the sweetness it should possess. It smelled of desperation and agony. He won’t want you when you smell like this, he won’t want you, he’s gonna leave, and then you are never going to have a pup, stupid-
“Fuck,” Kal huffed, eyes shut tight. His heaving breaths audibly and visibly stopped. “Can’t think when you smell so good, B, jus’ wanna make sure you’re sure.”
A sick rut scent rose higher in the air, imbalanced and heavy and mixing perfectly with his own. What a pair, the last lucid part of him thought. I broke us both.
“I know you don’t like alphas, I don’t wanna… wanna… hurt… Can be so good for you, B, I’ll be so good, jus’ wanna help…” Again there was that underlying scent of fear. Bruce’s resolve shattered even further.
“‘S’okay,” he muttered and reached up, giving him a light pat on the cheek. “You’re good… Good Alpha… Always listening so well… Smart Alpha… Gonna give me what I want ‘cause you’re so good and… and smart and… and…” Bruce melted back against the tangle of blankets and the cape, Kal nuzzling up to scent him again. The toy laid forgotten to the side, He brought his hands up to tangle them in dark waves, gripping securely so he could lead his mate upwards. “Kiss,” Bruce urged, “kiss, gimme… kiss.”
That was all the urging it took for him to be captured in something heated and messy, alpha pheromones leaking directly into his mouth like a venom. He let out a sharp whine and wrapped his legs around a sturdy waist, tugging and holding dark hair to hold him at any angle he so desired while he was all but consumed.
Waited too long, his hindbrain supplied, could’ve had this the whole time and you were too stupid to take it.
A hot slick tongue kept sneaking deeper and deeper into his mouth, their teeth occasionally clicking together while the heavy, frantic grind of their lower bodies finally kicked in. A breathless whimper escaped him, using up the last of his oxygen while his lungs screamed for air and pleasure licked up his spine. The emptiness was back with a passion, aching and burning in his core and in his lungs. He gave light, frantic pushes against Kal, but could already feel his pleasure beginning to mount.
Finally Kal got the hint and drew back to nibble at his lower lip, low, pleased rumbles seemingly shaking the both of them through their hurried grinding. The adjustment to allow him to gasp for air temporarily shifted Kal’s hips into the most delicious angle despite the thin layers remaining between him. Finally another breathless moan escaped him, only spurring his mate to press firmer, move faster, and finally, finally, finally tip him over the edge.
Bruce came with a breathless shriek, moaning and whimpering and digging his fingers into the fabric of the Tshirt that was beginning to become deeply offensive. “Off! Take it off! Why are your fucking clothes still on!”
“Just- please, please,” Kal panted, hips still pressed to his in a frantic chase before his breath hitched further.
Oh, he’s close! Yes, yes, yes, yes, yes, watch!
Just like that Kal came too, a strong rush of scent coming off of him. Matematematemine and moremoremore invading every single one of his senses, shivers racking the alpha’s body. He looked… stunning. The most beautiful thing Bruce had ever seen, glassy eyes locked on him, lips parted. Despite the wet spot he could see at the front of their pants, it didn’t look like a knot was swelling.
He whined and pulled at the offending fabric again, staring pointedly at the dampness. He knew his own pants and briefs likely looked similar, but didn’t feel the same irritation. “Stop- Stop wasting it!” Bruce hissed, hearing a couple stitches snap in their shirt when he was finally allowed to pull it off. “Everything else goes in me, do you understand?!”
“Yessir!” Again Kal moved too fast for his eyes to track, but before he could blink the both of them were fully exposed. The Alpha was hanging hard, heavy, and large between his thighs, at least a couple of inches longer than the toy and still dripping. His hips were scooted farther back, presumably to avoid any unwanted contact, positioning Kal’s lips closer to his collarbones and chest than his face and neck.
Bruce licked his lips and inspected it, the slightly swollen knot and feverish red color, all sheened over with the most absurd amount of precum he’d ever heard of. Even from his brief stint in med school, he knew this was a lot. Was hyperspermia a common thing for Kryptonians? Is it hyperspermia if this is normal for his species? How much can I-
Every single thought left him when a burning hot mouth settled over one of his nipples, suckling and nipping at the inflamed and sensitive skin. Bruce’s back arched without him telling it to, pressing him more securely into his alpha as more slick leaked from him. He knew he’d always produced a lot, but he’d never been this wet. He barely found it within himself to drag his own hand lower, his own fingers caressing his swollen clit and driving a sharp gasp from his lips. “Oh-! Alpha,” he panted.
One of those large hands replaced his own, hot breath hitting his chest when his swollen nipple was released with a soft pop, the very same mouth frantically repeating the actions on the other side. “Sorry,” mumbled against his skin, sharp teeth giving a gentle tug, “sorry, sorry, you’re just so- so- just so perfect, I had to… mmm…” There was firm suction around his nipple again, a hot tongue depositing drool to leave this side of his chest slick with spit as well while that hand stayed maddeningly still.
Bruce whimpered and grinded his hips into the touch, letting out a long, loud moan that was more pornographic than he knew he was capable of creating. He let out another at just the obscene, satisfied sound it earned from his mate, muffled against his skin.
The very same scalding mouth began kissing lower and lower, pausing briefly at his navel to dip his hot tongue in. Bruce’s mind unhelpfully imagined what that would feel like even lower, invading his pussy. The disconnect between his already fried nerves and the imagined sensation paired with the startling sensitivity of his belly button drew out another pathetic sound, hips once again writhing with a desperate mind of their own. “Kal! Kal! Alpha, please!”
Finally that sinful tongue licked lower, trailing across the light peach fuzz of his stomach and down, the alpha nosing against the crease of his thigh before his tongue flicked out again. The hand was removed, gleaming blue eyes studying the webs of slick left between his fingers and inflamed pussy, tongue lapping up the strand connecting his pussy to his hand with a satisfied moan. “So wet for me, Bat,” he purred. That slick hand came to rest on his inner thigh, pushing his legs open further. “Mm, you said that was your favorite toy? D’you like dripping slick over my crest?”
Bruce was just opening his mouth to respond when Kal licked him slowly, from the bottom of his opening all the way up. Tears were forming in his eyes already again, hips attempting to push himself further down despite the hands holding his thighs firmly in place. His Alpha’s mouth settled over his clit again, nose pressed firmly against his mons pubis. “Fuck! Fuck, too much, gonna-ah-aaahh!”
His back arched further, hips giving pathetic little twitches while Kal shut his eyes and dug in. He reached his peak embarrassingly fast with a startled yelp, unable to form any words as heat claimed his brain. Bruce could practically feel his eyes roll to the back of his head, Kal nowhere close to letting up. He dug his fingers into that gorgeous, jetblack hair, loud whimpers and moans escaping him as that tongue trailed lower.
“Shit!” Finally he had part of Kal inside of him, tongue pushing deep with obscene wet sounds coupled with slurping.
Is he fucking drinking it?!
A shock ran down his spine when yet another orgasm hit him, letting out a full scream this time. Does it count as another if it never stopped?! He decided it did. Alpha’s mouth could probably deliver endless, magic orgasms.
Bruce drew in ragged gasps and sobbed through another series of moans, Kal’s tongue wriggling deeper. Strong arms wrapped under his shaking thighs to pull him closer, hands rubbing up his hips and flanks while the unbearable pleasure continued on. “Kal, Kal, please, I ca-aaah! I can’t! Fuck!”
Shimmering violet eyes looked up at him, the Clark Kent mask fully gone between his thighs. Alpha disconnected with a wet sucking sound, pressed a soft kiss on his clit. “Shut up,” he huffed, “I’m starving.”
A wrecked laugh escaped him while he was stared down, his alpha’s tongue flicking rapidly across his clit and wrenching out another loud moan. Before he knew it he came again with a rush he’d never felt before, uncontrollable amounts of slick gushing from him while that burning hot tongue tried to bury itself deep again and Kal drank. He drank and drank and drank, lips sealed around him as gush after gush of slick ran out. He hadn’t even recognized that he was almost screaming, too focused on the way he could hear Kal swallowing it all.
“Oh fuck, fuck, fuck, fuck, yes, yes, yes, yesyesyesyesyesyes, fuck! Kal!” His body writhed as a fresh wave of pleasure overtook him, slick continuing to spill. He didn’t even tense when he heard footsteps outside of his bedroom door, or when he heard it creak open just enough to talk, but not look. Clearly, Alfred was worried at the screams.
“Is everyone alright?”
“God- fine!” He yelled, fingers still tangled in dark hair. “Fine, we’re fine, go away!”
Kal’s eyes were gleaming with amusement. Stupid, arrogant Alpha, and his stupid, perfect mouth, Bruce thought.
“Just checking in, Master Bruce. I heard… screaming.”
“We’re fine!” Bruce insisted.
Finally Kal’s mouth disconnected from him with a slick pop, a line of slick and saliva connecting his lips to Bruce’s pussy. After one last swallow he cleared his throat, not withering even a little bit under Bruce’s challenging glare. “Just means I’m doing my job! Your pup’s doing great!”
Bruce growled and lunged at him, earning a breathless laugh from his alpha. “You’re supposed to put a puppy in me, not-”
“Very well,” Alfred interrupted, clearly not interested in hearing it. He probably heard the obscene slurping sounds as it was. Bruce should be embarrassed. Probably would be later. That wasn’t important, then. “Always one call away.” With that, the door clicked shut.
“You incorrigible little-”
Kal just laughed underneath him, grabbing his discarded cape to wipe the bottom of his face of excess slick. “If you still know the word, uh- uh… in.. um… incorrigible,” he said, clearly struggling to stay lucid, “I’ve not done enough.”
“Jerk,” Bruce hissed, looking down at the steadily dripping dick between his alpha’s legs and feeling another painful wave of emptiness. He should stretch, he knew he should, but heat would have loosened him enough to partially take his favorite toy and the burn couldn’t be that bad despite the rather… glaring size difference. He refused to believe it could hurt. He knew it probably wouldn’t until his heat was over. That was a chance he was willing to take. The tongue had to be enough, because he wasn’t about to have his second squirt ever only on his alpha’s fingers when that thick cock was an option. “Put it in me.”
“It’ll hurt!” Kal insisted, squirming uncomfortably. “The toy’s smaller than me and if that’s the biggest you’ve got-”
“I need it in me! You’re gonna make me squirt again and it’ll be on your stupid fingers!” Bruce protested, reaching down to take hold and reveling in the sharp gasp it earned. It was… probably thicker than he could take without stretching. Even in heat. He let out a whine, smackingly weakly at his alpha’s chest with a shaking hand. “What did they feed you on that farm?!”
“Lots ‘n’ lots of sunshine,” Kal hummed and stole a soft kiss, seemingly unbothered. “Y’wanna see what these fingers can do?”
“The fucking sunshine didn’t make your dick grow!”
Stupid! Stupid, Alpha! Can’t believe that’s gonna be the father of-
“Fuck, what are you doing?!” A thick finger was already slipping inside of him, filling him far more nicely than any time he’d attempted using his own fingers. An electric thrill of pleasure crawled up his spine even though nowhere particularly sensitive had been caressed, just that warm palm pressed carefully against his clit and the miniscule amount of friction provided every time that finger moved.
“Gotta get you open for me, Bat. Can’t put a puppy in there if I can’t fit.”
Another nuzzle against his neck while a second finger slid in, Kal correctly gauging that it would fit without struggle. The scenting this time was heavy, he could practically feel it lingering on his skin over his inflamed scent glands. It seemed every part of him was screaming out for a bond. Maybe that’s for the best, too. Puppy needs a father… pretty puppy, his hazed mind thought, soft moans escaping him again.
“Wanna lay back?” Kal asked, easing him onto the nest again without waiting for an answer. “Can I- want… d’you want my mouth again?”
Wantwantwant, yes!
Instead of voicing that thought he gave his head a small shake. “We’ll never get anywhere if you- nnn- if you just- just- keep eating me,” Bruce huffed. “Mm, your tongue is stupid-”
“Think you mean it makes you stupid.”
“Can-nnnn-n’t believe you’re my mate,” he huffed without thinking. His hips squirmed again, thick fingers caressing his insides. “You’re a jerk!”
Kal just laughed again, littering kisses along his neck and shoulders. “My mate,” he breathed. “Omega… omega… mine?”
Bruce whined and turned his head, bunching up the cape to hide his face against it. He couldn’t handle that piercing gaze on him even though he was certain Kal could look through it. “I hate you,” he mumbled, letting out another soft moan.
“Want my mouth on you, make you cum a million times a minute again,” Kal mumbled against his collarbones. “So responsive… Omega…”
“You make a habit of taking feral omegas to bed?” Bruce attempted to change the subject, but knew Kal could probably smell the dread and disappointment coming off of him at just the thought.
“Wh- no!” The fingers in him stopped moving, his other hand moving the thick, red fabric away from his face. “No, we talked about this, I never- I never wanted to-”
“You’re a romantic idiot who thinks every human has a true mate, so you never fucking touched one because you’re too fucking good to be real,” Bruce huffed, giving his hips another squirm to spur him on despite the reassurance the reminder gave him. “Idiot who clearly thinks about this way too much because you’re acting like I’m depriving you one last meal.”
“I could live off you alone,” Kal purred, fingers shifting in him again.
“Tha-aah! That’s your rut talking, stupid Alpha!” He huffed and started grabbing for the cape.
“I get to use my mouth if you hide your face again.”
“I hate your stupid mouth!” Despite his protest he didn’t attempt to hide, instead opting to keep his eyes closed securely.
A third finger slipped in and he could just make out the scent of alpha satisfaction through the heat and rut scents. He could imagine the look on Alpha’s face, smug and self assured. “You loved my mouth until Alfred came to check on you,” Kal reminded, not unkindly.
Bruce growled, embarrassed when it was cut off by a moan. This wasn’t as intense as Kal’s mouth and nowhere near as frenzied, but he did appreciate the brief slowdown to catch his breath. “I got- fuck- I got distracted! You aren’t here to have fun!”
“The only one getting off here is you, Princess,” Kal said with an almost audible eye roll. “I came once and you’re torturing me for it. Is that what this is? That why I can’t use my mouth?”
He growled again and whined, slamming his fist against the plush materials of his nest. Probably more forgiving than trying to hit the alpha again. “Hate you so much! Hate your stupid fingers!”
“Want me to turn on the vibration?” Kal asked, fingers giving a light buzz against a previously neglected sensitive spot.
His back arched again, a loud moan escaping him despite not nearing his peak. This was infuriating. “Want your fucking dick in me, hurry the fuck up!”
Despite his growling and panting he was still given a frantic kiss, the fingers in him finally moving quicker and brushing up against spots that had him seeing stars. He needed to cum, and he needed to cum immediately. His body moved without his mind, grabbing the cape and hiding his face again.
As promised, Kal’s tongue was between his legs again, rapidly flicking against his clit. “Fuck, fuck, fuck, c’mon!” Hot tears welled in his eyes. His hips grinded back against Alpha’s fingers and tongue shamelessly, hands tangling in messy, black waves yet again. “Yes! Yes, yes, yes, yes, fuck, yes!”
Yet again he was almost screaming, throat hoarse. He hated the pleasure and heat licking up every single one of his nerves, the infuriating fervor in every single lick and touch. Finally he was cumming again with another shout, writhing as slick rushed out of him. “Alpha, Alpha, Alpha, yes, fuck, Kal!” He almost sobbed, pulling hard.
Thankfully, Kal had mercy and backed off. The Alpha grabbed the edge of his cape again and wiped his face, fingers slipping out of him. Bruce panted, not even caring that slick fingers came up to gently stroke his cheek and jaw.
Good Alpha, good Alpha, perfect Alpha. My mate, mine, mine, mine, mineminemineminemine.
It took a moment, but he eventually realized just how loudly he was purring. It was rough and hitching, his throat aching in protest, but he couldn’t help himself. Bruce reached up and wrapped his arms around Kal’s neck, pulling him down into another kiss. He desperately wished for something more gentle and tender, but rut was visibly wearing down his alpha. This time he could taste himself on Kal’s tongue, pheromone heavy saliva and remnants of slick leaking into his throat. To his surprise, it soothed the ache.
He tensed when there was a harsh nip on his bottom lip, a low growl escaping Kal. Bruce worried if he’d done something wrong before he heard motion outside the door. Of course. Alfred.
Kal melted against him after a moment, scenting him almost frantically. Alfred must have left, either smelling full rut or somehow hearing the growl despite how quiet it was. Good decision, on Alfred’s part.
“Clark,” he said to try to get his attention, only receiving a light bite for his trouble. “Kal.” Finally a soft hum of acknowledgement. “It was only Alfred. You know Alfred. Beta Alfred. No challenge here, Alpha. Nobody’s gonna take me. Understand?”
“Yeah,” Kal whispered, pressing a light kiss on his scent gland and whining. “Sorry. Promised I’d be good.” He could hear the alpha’s teeth chattering with the effort of holding back, whole body shaking.
This alpha was no danger to him. This Clark would never turn his back on humanity, Bruce would be there to prevent it no matter what. “You’re so good, Alpha. Bein’ so perfect,” he reassured. If it was this difficult to think after being satisfied repeatedly, he could only imagine the difficulty Kal was having. It was selfish, but he couldn’t let any of it go to waste. Everything needed to be in him or not at all. “Bet you’re all pent up, huh?”
“Fine, fine, it’s fine,” Kal mumbled, nosing along his jaw with a pathetic whimper.
He’s frying his own brain, Bruce thought and tried not to laugh. He was still very much in heat, but he’d not been holding back much. Seeing Kal like this was… cute. Precious, even with the irritation he brought.
“‘S’gonna be worth it, Alpha,” Bruce whispered. “So worth it when our pup is here.”
Another miserable sound, teeth dragging over his neck as a warm hand settled on his lower stomach again. “Gonna be nice ‘n’ safe in there, B, nothin’s gonna happen to ‘em.”
A cold chill ran down his spine, flashes to that alternate universe making his stomach turn. “Yeah,” Bruce said, feeling almost like he was going to vomit again. “Yeah, yeah, I know I can't let anything happen, I-”
He was cut off with a soft kiss, dragging a sharp whine out of him. “What's so scary, Bat?” Kal asked in a whisper, glassy eyes locking on his.
God, he looks so innocent, Bruce thought, chest aching. Is this what he looked like then, too? Before…
“You kinda- kinda- you lose a baby and- I mean, in one of those other worlds you- Kal!” He let out another sharp whine, the heartache making his heat even more unbearable.
Not a good mix, need to stop, need to-
“Oh.” There was a flicker of clarity in those eyes, another chill running down his spine. “Oh, sh- Bruce, no, no, no, that's not gonna happen here, that'll never happen here-”
“You don't know that! You don't-”
“I do!” Kal said and sat up, frowning down at him.
Alpha irritation was coming off him in waves, but Bruce wouldn't look away. Not now. He had a feeling it wasn't really directed at him. If it was, well, he deserved it, anyway. Stupid Omega, keep poking the bear, why don't you?!
“I saw it,” Kal admitted, looking away. “I saw, before I handed it off to you, and I- and- just didn't like what I saw! I never- never saw the little boy you saw! Just saw bad! So I gave it to you, ‘cause you're smart, and- and- and you always- B, you always know what to do and- Rao, my head! Gave it to you ‘cause I know you'd never- you'd- nnnghh- you'd never let it happen! You're smart and good and you- I could never fight you… Could never fight my mate…”
Rut must be making it difficult to think. If it was anything like how he felt in the worst of his heat it had to be difficult. Still, this was important. He gave his own head a hard shake. “I don't know if I-”
“Mark me,” Kal insisted, glazed eyes still holding pain. “Mark me, while we do this, and I'll be- I'll be… yours. Don't even have to lemme bite you, I- I get it.” He nodded. “Then I'll be yours and you can stop me.”
“You'd give me that? Without anything- God- without anything in return?”
Those beautiful, violet eyes were already brimming with tears again, frustration and needneedneedmateplease and sadafraidhelp hanging heavily in the air, all from Kal's end. It really must've scared him. No wonder he looked so terrified the day he left the device in the cave.
“Did you- uh- did you think I was gonna put you in, uh, shit, con… jail- no... pri- container… contain… contain- contain- shit, what's the word- containment! When I saw? Think I was gonna container- contain you?” He gave himself a few smacks on the face, trying to snap himself out of his haze.
“Wanted you to!” Kal said with a growl and shrank back.
Bruce wasn't afraid. That growl clearly wasn't meant for him. If anything, he suspected Kal was attempting to threaten himself away. Alphas were strange like that, he knew, fighting anyone and anything. Sure. Maybe, in stress, they'd try to fight their own instincts and result in challenging behavior, the only lucid part of him, small as it was, said. Half the reason why he'd be trying to crawl out of his own skin. Poor, stupid Alpha.
“One of- someone- I deserved- deserve to pay for what happened! Just couldn't ask and- and- you never- you never said anythin’ and- and- Rao, you gotta do somethin’, ‘cause it's- it's- it's-”
“Scary,” Bruce finished, taking mercy on the poor alpha and his stammering. He sat up the rest of the way and drew in a shaky breath, reaching out a trembling hand. Relief flooded him when Kal pressed his cheek into the touch, those gorgeous eyes falling shut and sending the tears tumbling down his cheeks. He knew what was happening, but getting those words to his mouth seemed insurmountable. What he knew, what he could do, and what he was able to say were all in wild stages of disconnect. Bruce couldn't imagine how difficult it must be for Kal.
It was Alpha's turn to choke back his sobs, seemingly torn between pressing into his touch and wanting to run. Horny and sad was a miserable combination. He couldn't let this stand. “Help,” Kal got out between ragged breaths, clearly warring with his own instincts.
Not a threat. Not at all. Safe.
Bruce gathered the strength he had left and just about pounced on the alpha, finally scenting him in return. “‘S’okay, ‘mmmnot afraid, Kal, ‘s'okay, not scary at all,” he muttered. “Stop freezin’ up on me, hold me!”
“‘Kay,” breathed out next to his ear, shaking arms wrapping around him. Large hands pressed flat against his back, one in the dip of his spine and the other between his shoulderblades. Kal was pointedly avoiding scruffing him or even coming close to it. So desperate to try to control himself, even at a moment like this.
“Snap out of it,” he whispered, pressing open mouthed kisses on Kal's neck and jaw. “‘Mmm here now, gonna be okay, Alpha.” Bruce gave a long lick across a heated, inflamed scent gland before blowing on it softly and reveling in the choked off sob.
“Dunno what to do…”
Bruce's lips settled in a small smile, Alpha becoming putty under his touch. Maybe this wasn't so bad. His Kal could never be bad. “You're gonna give me a pup,” he reminded quietly. “Gonna get in there all nice’n deep an’ you're gonna gimme a pup… gonna mark you as mine.”
“Smart Omega,” Kal mumbled. “So smart… always know what to- what to do…”
“Will it- Will I break my teeth?”
“Nuh-uh… my… rut should- it should- skin softer on my glands, easy bonding.”
So Kryptonians were isolationists, but not meant to be solitary creatures. That explains… most of the aggressive behavior in other universes, actually, he noted.
A warm hand settled on the back of his head, guiding his lips back to one of the inflamed glands on Kal's neck. The scent was so strong there was no possible way to keep his mind clear. He opened his lips again and gave it a slower lick again, near melting as pheromones and hormones took a more direct route to his system. “In me first,” he huffed, breathing already getting heavier.
The arousal never went away, but now that the important conversation was out of the way he knew he was going to fall deeper into heat. They had time. He wanted to be thoroughly bred and then he'd see how easy it was to sink in his teeth.
Kal just nodded and rolled them over, Bruce settled on his back with his legs spread wide. Glassy eyes landed on his pussy again, Alpha giving his lips another lick. Bruce couldn't stop himself from growling in frustration yet again. “No,” he said firmly, reaching down to grab Kal's dick. “This. This goes in, not your fucking tongue!”
A pathetic whimper escaped the alpha, the man shifting forward. Bruce dropped his cock, jolting at the weight of it when it landed on his tummy with a loud slap, still leaking a copious amount of precum. This was about to get very, very sticky beyond just the mess of slick between his thighs.
“I know how it works.”
Bruce narrowed his eyes, Kal shifting forward. He looked back down at his stomach, just to see where the tip was going to end up now that they were flush against each other, and felt his head start spinning. Deep in his guts. He was going to feel it for days after his heat. “Oh, fuck…”
“Yeah, that's the idea,” Kal said with a dry laugh.
Another irritated growl escaped him. “Don't get cute with me! God, you're the worst!”
“D’you want your puppy to look like me or not?”
“Oh, I hate you!” Bruce hissed. His anger was, unfortunately, short lived, his hiss devolving into a whine.
Kal shifted back just enough to begin dragging his shaft along his pussy in long, slow rolls of his hips. It was heavy and firm and he needed it inside more than he'd ever needed anything in his entire life. Part of him worried that there wouldn't be enough room, but he knew he'd find a way to take it anyway. It would fit, there was no other option.
“Just gotta get myself nice’n wet so I can get in there,” Kal muttered. His eyes looked distant even though they were trained right on Bruce.
Alien thing or alpha thing? He wondered before another jolt of pleasure ran up his spine, their tip catching against his clit.
“Fuck, what's wrong with you?! Just put it in!”
Pretty eyes looked back into his, glittering with amusement again despite the haze of rut. Over and over the tip brushed against and then over his clit, providing mind numbing stimulation.
“Evil. You're evil.” Still, he had to admit something about it was painfully arousing. Their breathing deepened together, soft huffs and airy moans filling the rapidly heating space. “Gonna be so mad if you cum like this, Kal.”
“You're angry anyway, Bat.”
Bruce shifted his hips impatiently, whimpering when the tip caught against his hole before slipping right back out again. “Kal, I swear in the name of all that is holy, I'm gonna lose my mind and then I will find a way to lock you up!”
Kal's lips twitched into a small, amused smirk, still dragging his length lazily along Bruce’s pussy. For an alpha so deep in rut, he didn't seem to have much sense of urgency.
Is he just playing? Is that just as satisfying to him? Is he trying to prove that he can be good and patient? Is he mad at me for telling him to hold it? Payback? Bruce settled on the answer to all of those being a simple, yes. Kal loved playing with him. There was no reason why it wouldn't extend to mating.
“Say it,” he huffed. “Whatever it is that's got you looking all cute, just say it!”
His mate let out a soft hum, using the hand he'd been steadying his penis with to lightly tap against Bruce's vulva. He drew in a sharp gasp, a shudder of pleasure zapping through him at the change in contact.
“Well,” Kal purred.
This is gonna be bad, he thought.
“Just doesn't seem real. Looks like a… mmm… like a wet dream,” he said with a small nod.
Okay, not that bad.
Kal's smirk grew.
It's gonna be bad, he corrected again.
“Like one of those, uh, pop ups.” Kal couldn't even stifle his little laugh. “Desperate omegas near you! Lonely omegas in heat need to fuck!”
Bruce growled and leveled him with his most unimpressed expression, but had a feeling the heat softened most of the edges because it didn't seem to be too effective. “How charming,” he deadpanned, frowning.
“Mmn, that what I am for you, Princess?” Kal asked, continuing on his little rant. Bruce rolled his eyes, but couldn't hold in his soft sounds at the way he was being toyed with. “Your heat relief alpha? Gonna send me packin’?”
The small, amused smile on Kal's face was difficult to remain angry at when pleasure was building again. He grabbed the alpha's free hand and brought it to rest over his womb again, hips stilling for a moment despite the gentle tap of his tip over the entrance. “Mmm… you owe me more than relief. You owe me a puppy, and he's gotta look just like you,” Bruce hummed. Sparks of pleasure flickered every time the tip threatened to slip in. “Be a good stud and sire my pups. I could see myself keepin’ you.”
Kal's eyes gleamed with affection as he leaned down. “Omega,” he whispered, like they were sharing a secret, “will you keep me anyway?”
Bruce's heart fluttered. “Yes- yeah… Yeah…”
“No more silly games, ‘kay?” Kal's lips brushed over his, the hand on his stomach rubbing in light circles. “Can't want to get inside you.”
“Been begging for it and you won't give it to me!” Bruce hissed. “You keep teasing me!”
“Mm sorry, been unfair to you. Should I-”
“Put your mouth on me one more time and I'll scream!”
Kal's eyes sharpened as he gave his lips another lick. “Yeah, you will.”
Bruce shuddered and looked away, rubbing at his face. This was getting painful. At the very least he knew his alpha was obsessed. Kal would never be able to act this well in the middle of his rut. This oral fixation might become an actual issue at some point. “I'll make you a deal,” he said and looked back up, attempting to scoot his hips closer.
“Mm?”
“Listen close, ‘kay?” He looped his arms around Kal's neck to prevent him from moving away, pulling him into a short kiss. “You get to lick up what leaks out.”
“Rao… promise?”
Bruce shivered at just the thought. He'd been mostly joking, but the look on his alpha's face told him that was going to be the plan. “Yeah- yeah, promise. Just don't go sucking it all out.”
Kal gave him another kiss and smiled against his lips, hips twitching forward to keep up the light stimulation. “We'll have more than enough to get you a puppy,” he promised. That warm hand pressed down on his stomach again, almost as though imagining a soft swell already.
“What if it doesn't take?”
“Then we'll try again,” Kal said, nodding. His rut scent was only growing stronger. “I’m your mate, B, I'll give you a baby- give you- mmn- give you the whole world if you want.”
“No world domination, stupid Alpha,” he mumbled, squirming in an attempt to finally slip him inside. “C’mon, c’mon, need it.”
Alpha nuzzled against his neck to scent him again, still the scent of an imbalanced rut, but finally clinging to his skin the way it was intended. He hoped his own would stick to Kal’s skin. It certainly would after marking him. He can mark me and then mine can mix too, he decided, baring his neck further at the onslaught of happy alpha pheromones.
“Need in,” Kal mumbled, hips twitching forward again. “Please, Omega…”
“Yes, Alpha.”
He hissed in irritation when Kal sat up, one hand moving to his hip while the other settled around an inflamed knot. Alpha should stay in his arms. “Patience, Bat,” Kal huffed at him, giving another gentle tap before beginning to press forward.
His growl cut with a sharp gasp, a thick tip pushing its way in. “Kal!” Despite his familiarity with toys, it felt all new. Bruce felt clumsy and disconnected from his body the way he had during his presentation, aches he'd done a phenomenal job ignoring flaring back to life. “God, took you long enough!”
“Puppies should be- mmnn- puppies should be made with love.” Kal's hand trailed from his waist to his stomach again, slowly sinking forward with soft pants. “Can’t have a- have a- nghh- a puppy if Omega doesn't… doesn't feel good.”
Bruce would have rolled his eyes if they weren't already rolling back in his skull, Alpha indulging him with short, shallow thrusts. It couldn't have been more than a few inches inside, truly just the tip when he considered what Kal had to offer. “Sap,” he mumbled.
It was exhausting already. Heat always made him feel slow, but now it felt like every synapse was firing at half speed. By the time his own moans registered, Alpha’s thrusts were sinking deeper and deeper, a burning hot mouth huffing against his neck.
“Sorry, sorry, sorry,” Kal mumbled over and over again. His entire body was shaking, unneeded breaths coming in unsteady and hitching rasps.
The scent of rut was growing heavier still, fevered and unmistakable. Mixed with his own heat it was almost enough to make him delirious. The most delicious scent he'd ever caught, and it was all just for him.
“Good Alpha,” he breathed, clawing ineffectively at invulnerable skin. Hardly anything had happened yet and already he felt desperate. “Gimme more!”
That earned him a loud groan, Kal's hips hitching before he obeyed. Another inch, maybe more, slid in, drawing out whines from the both of them. He felt stuffed. There was more, there had to be, but he was certain he could fit a few more inches. He could do this, no problem.
“Halfway, Omega, doin’ so good…”
It was Bruce's turn to groan, irritation and heat lacing together to draw another growl from him. “That's half?! What the fuck, Kal?!” He couldn't stop himself from growling just a little bit louder at the breathless laugh it earned him.
“Told you- hh- it's a little bigger thannnn you're used to, Princess!”
“You're the worst!”
Before he could say more, Kal pulled almost all the way out, pushing back in to what he now knew was half. Half! His back arched without him thinking about it, drawing a pathetic whine from his throat.
“Kal!”
“D’you want the puppy or not?!”
“Just give it to me!”
He rolled his eyes when Alpha leaned down, but still returned the kiss anyway. The entire process should be disgusting. Bruce knew that much. Tasting himself on Kal's tongue should make him shrink back, but all it did was renew the fire in his belly and the heat licking up his spine. He needed.
It was unfortunate when the kiss broke. There was nothing left to muffle him and with the way he just couldn't seem to close his mouth, Kal was stuck hearing every little sound he made. Even worse was the almost-sob that escaped him when teeth scraped along the side of his neck, Alpha pushing deeper inside.
Bruce could feel the tip brushing up against his cervix. That was as deep as he'd ever gone himself. This was doable. It was nice, even. “Hnn- how- fuck- much more?” He asked, forcing himself to open his eyes.
He whined again when Kal sat up, their eyes locked on where they met. “Rao… couple inches,” Kal muttered, hand coming to rest, presumably, over the space he was currently occupying. “Takin’ it so well…”
“Kal!”
“You got room!” Kal insisted, giving a small push deeper and shuddering at the same time Bruce yelped. “You'll make room for me, won't you?”
“Not- fuck- not how it works!” Bruce smacked at the padding under his hand, back arching further. “Feel that, dumbass?! Called a fucking cervix! Stuff goes out, not in, stupid!”
If the little smirk on Kal's face was anything to go by, he definitely had something to say about that.
“No- no, no, no, you are not!” He almost shrieked on a harder thrust, pain and pleasure zipping along every nerve in his body. “Quit it!”
“Mm, hold on, hold on, we'll get there. If you don't- nghh- don't, uh, like it when… shhhhhhhhiii-hhh… got somethin’ called a fornix,” Kal huffed, looking slightly dazed, “an’ that's what I'm aimin’ for, Princess… Try?”
Bruce could feel himself starting to tear up again. Both hands were holding his hips now, shifting his position slightly while giving small, experimental thrusts. It was maddening how good it was starting to feel. “Yeah, yeah, okay,” he mumbled and reached forward with one hand to grip one of their wrists.
“I'll, umm, I'll pop right in around,” Kal said with a small nod. “Not inside. Know y’were worryin’ that pretty head.”
“God, what is your problem, Kal?!”
“Tellin’ you what's happenin’, pretty thing,” Alpha purred.
“How d’you even know that?! Insufferable little- nngghh!” Another insistent thrust cut him off, drawing an almost pained sound out of him. Bruce wasn't even aware he could make that sound. The motion repeated again, Kal's tip pressing firm and deep with each little roll of his hips.
Bruce could hear motion outside the door again, which meant he was certain Kal could hear it. The little glare sent in the direction of the hallway drew a breathless laugh out of him before the effort was redoubled. “Eyes on- mmmnn- eyes on me, big boy,” Bruce huffed.
Kal nodded quickly and looked back down at him, chewing at the inside of his bottom lip and furrowing his brows for a second. “Just Alfred,” he mumbled. “No challenge…”
“Good Alpha, so- so smart!”
The smile it earned him would have looked innocent any other time. Bright and warm. Puppy’s gonna have that smile.
“Doin’ okay?”
Those pretty violet eyes locked on his again, the hands on his hips squeezing lightly. The knowledge that Kal could shatter that bone without any effort made his head spin.
“Mhmm… Deeper.”
“Okay- okay… okay…”
Bruce swore he heard and felt a soft pop, head falling back as Kal's hips finally pressed flush against him. The moan his Alpha let out was pure filth and must have been loud to hear past his own shriek. “Too much, too much!”
“Breathe.” A warm hand settled over his stomach again, nice firm pressure. “Look.”
Oh…
Bruce forced himself to tip his head back up, another groan escaping him when he saw the small bulge in his lower stomach. He drew in a shaky breath and moved his hand from their wrist. Placing his palm over it was strange. It didn't do much for him, he already felt stretched full and that wasn't changing, but it clearly did something for Alpha.
“Feel that, Kal?” He asked and pressed down, eliciting a hitched moan. “Feel good?”
“Uhhhhh huhh.” Kal gave a small nod. He looked and smelled entirely lost, hips giving tiny twitches.
He couldn't stop himself from laughing at just how dazed Kal was. If Bruce had to guess, it wouldn't take more than a few good thrusts to finish him off and he wouldn't be far behind. His lips settled in a small smile as he rubbed his stomach, drawing in every sound he could. Another breathless yelp escaped him when Kal gave a small thrust before he laughed harder, head falling back again. “Fried your brain?”
“Mmm…” Another small twitch.
“Kal… Gotta move.”
Alpha nodded again, burning hot hand resting over his. “Hold,” he said before pulling back.
There was another soft pop and another yelp from the both of them, but he definitely felt it. Pushing right up under his palm and giving his stomach a tiny swell. “Fuck, this is- this is gonna be a thing with you, isn't it?”
Bruce arched his back further while warm hands slid back to his hips. Finally that steady pace picked back up, hitting places in him that he didn't even know existed until that point. He was aware his mouth was open, but he couldn't focus on what sounds were coming out even if he wanted to.
He was, however, deeply aware of every touch. Kal's hands were trembling where they held his waist, hips hitching on every thrust. Every sound out of his alpha was shaken. Bruce was beyond proud to have this kind of impact. It didn't matter that rut had to be part of it. This was all for him.
Even those thoughts left him when Kal started pushing harder, hips snapping firmly against his with every thrust. He knew it wasn't deeper, there was no way it could possibly be deeper, but it felt like it.
Part of him was aware of the rapidly inflating knot, stretching him further, but he was too busy thinking of the absolutely delicious sounds it was pulling from Kal, loud enough to be heard past his own wails and moans.
“Close!” Bruce hissed, opening his eyes long enough to see a frantic nod before the speed increased.
Bruce desperately wished he could watch every expression on the alpha's face, but he couldn't keep his eyes open. Not when he was almost screaming again.
He reached up, Kal thankfully getting the hint and leaning down for a kiss. It was more teeth and tongue than anything else, but still perfect anyway. He tangled his fingers in dark hair again, shoving Kal's lips away.
Bruce pulled him down further as the thrusting reached a fever pitch and bit hard at the junction of the alpha's neck, the blood of a successful marking filling his mouth when he came. Satisfaction burned deep in him when he felt the knot lock in him, heat filling deep inside him.
Kal's sharp moan at being marked was going to live in his head forever on repeat. Even still the ragged tail end of it was going to drive Bruce into another pitch sooner rather than later. Kal panted, hips still twitching despite having nowhere to go with his knot locked in so deeply. Bruce still wasn't ready to unlock his jaw despite the labored breaths he had to take through his nose and muffled whimpers.
He was sure his alpha looked beautiful. He needed to let go. Just open your mouth, he thought, another low whine escaping him.
Kal was already lax and purring on top of him despite how he was shaking. “Did so good, Bruce,” Alpha mumbled.
Bruce forced himself to open his jaws and just about melted back onto his nest, licking the blood from his lips. He nosed along the hook of Kal's jaw in a light scenting, but refused the urge to lick the mark. He needed it to scar dark and deep.
His fingers tightened in dark waves as he made up his mind, guiding that warm mouth into another messy press of lips. “Need you to mark me, Kal.” The wounded sound the request drew from his alpha made his head spin. “Bite?”
Alpha’s mouth was right over his scent gland again, teeth dragging over sensitive skin. Every change in position shifted the knot against his own hypersensitive insides. If Kal's shivering was anything to go by, he needed more just as badly. A pathetic sound escaped him, which was apparently enough to kick Kal's instincts into action to try again.
Despite the lack of motion granted by the knot, Kal's hips could still rock and simulate plenty of motion, especially when he was already buried so deep inside. “Rao… tight… sorry,” he breathed, still trembling and holding still. “You want a mark? You're sure?”
Bruce wasn't sure if it was the bond settling already or not, but he could practically feel the apprehension despite being certain in his decision. “Yes, Kal,” he said with a small nod before dropping his voice to a whisper. “Clark…”
Both parts of you, Bruce thought, but wasn't sure he could communicate. I want all of you. Alien, human, Alpha, mine.
“You- you want it?” Kal asked, shifting to look at him. “Won't be mad? Wanna keep me forever?”
“Puppy needs a father,” Bruce said, smiling a little bit. He reached up with a trembling hand to smooth the lines between Kal's brows, resting his palm on a heated cheek after. “Bondmates conceive easier.”
Alpha's smile looked a little bit less genuine after that, but he still nuzzled against Bruce's hand. “‘F’course. For the pup,” he whispered.
Back up! Back! Rewind! Undo! Bruce's brain screamed.
Bruce drew in a shaky breath and made eye contact for as long as he could bear it. “For me, Kal,” he breathed. “Need you for me.”
“Anything for you,” Kal mumbled.
He could have died happy at that moment. He knew his Alpha heard his heart skip a beat. He didn't need to see the amusement in Kal's eyes to confirm it.
“What’s it gonna take for you to put those teeth to my neck, Alpha?” He asked, a whine already back in his voice. Bruce's smile grew when hot kisses were immediately placed on the hook of his jaw. “C'mon!”
Kal was laughing against his skin now, nipping playfully under his chin as his hips rocked again. “Mmmmmn! Here?” He asked, voice muffled.
Bruce shuddered and yelped, but started laughing too. He never imagined any of this could possibly feel so good. “No!” His heart felt so unbelievably full, breathless laughter catching on soft moans.
“Here?” Kal bit lightly at the hollow of his throat, hot breath ghosting over his skin.
“You- nghh, fuck- know where!” The pace picked up, prompting him to wrap his arms tighter. Bruce's fingertips hurt with how hard he was attempting to hold on despite the fact that the motion was mostly simulated. It was embarrassing how close he was again, and if Kal's barely muffled moans were an indicator, he wouldn't be coming alone. He'd heard active knotting rather than just tying and waiting for the swell to go down was intense, but even that was putting it far too lightly. This was almost transcendent.
Kal latched on the hook of his jaw and began sucking a hickey into his skin there, matching the other marks lovingly placed on his body. Finally a scalding hot mouth settled over his gland, sharp teeth scraping, but not biting.
“Please! Please, please, please, fuck!” Kal was pushing deep in, hard and fast despite being unable to truly pull out. It was a wonder he was able to find any words at all. Every higher function in his mind was gone and barely anything had happened.
“Here,” Kal huffed. Not a question this time. He was right on target, inside and out, and Bruce felt the hot flood in his guts grow as Kal bit down with a muffled moan of his own.
Any number of shrieks and moans had already escaped him when he realized he was coming too and by then it was too late to shut himself up. Bruce could feel blood and saliva pooling against the side of his neck, sharp teeth still lodged deep in his skin. Kal's hips were still stuttering, drawing more sounds from the both of them.
Bruce rested a hand over his lower stomach again, startled at the increase in distension. Did he really cum that much? He supposed it didn't matter. More inside of him was good. Good, good, good.
His nose wrinkled when he caught his own pleased omega scent. Wrong! Bruce thought, turning his head as much as he could to nose against dark hair. It was nowhere near as good as a full scenting, but he couldn't hold in his loud, hitching purr when he was directly hit with the scent of his alpha. Perfect!
“Don't lick,” he mumbled when Kal pulled back, still on the tail end of catching his breath. “Want a scar.”
“Okay.” Kal smiled down at him, blood tinting his lips. “That why you didn't lick me after? Wanted to give me a big scar?”
Bruce melted back into the nest when he was given another kiss, head swimming with the taste of his own blood. The more lucid part of him thought it was cute, hearing their purrs mixing in much the same way their breath did in every small gap left for air. A warm hand rested over his, guiding it gently across his tummy and making him purr louder. Puppy! Puppy! Gonna have a puppy!
“Did so good,” Alpha praised again. “Mmn… Took it all so well.”
Bruce gathered up his strength to flip them, moaning with Kal at the motion. The tug was almost painful with the reinflated knot, but he felt pleasantly full now that he'd settled. More lucid now that his pitch was over, but still hazed with heat. “Look so good wearing my mark, Alpha,” he muttered.
“You haven't seen yourself yet, Bat,” Kal practically cooed at him. The bond between them was as soft and warm as the nest, tender and fresh. “Feel okay? Didn't hurt you?”
“You were perfect, Kal.” He forced himself to sit up and placed a trembling hand over the swell at the bottom of his stomach. No pup yet, but the ingredients to make one. Bruce felt his lips settling into a smile. It felt clumsy and awkward, and he knew it was anything but the carefully practiced expression he usually presented cameras when asked to smile. “Look.” Bruce couldn't hold in the laugh that escaped him when he felt a small twitch of interest inside of him, Kal's face immediately going beet red. “Oh, you like that.”
“Of course I like it!” Kal hissed. “That's me in there!”
Bruce narrowed his eyes and gave him a hard smack, palm stinging with the contact. “Don't hiss at me, stupid!” Kal's eyes were giant, pupils blown wide. Bruce was certain by the ache in his hand that it would have left a mark on anyone else.
Despite wanting to laugh at clearly discovering something else Kal liked, he could see the alpha's brows furrow a little bit. Concern was leeching through the bond just as much as hot and more. He'd never understood what people meant when they said they could feel through the bond, but now he was wondering why he'd put it off for so long. This was awesome.
“Alright,” Bruce said and gave him a light pat on the cheek. “Look it over and tell me what we both know. I'm fine.”
Kal's brows knit deeper before the visible portion of his iris shifted color, a warm hand repositioning his. Clearly rut was setting in deeper. Paired with the bonding hormones he looked like he was losing his grip on sanity.
“Okay. You're okay. You um…” Kal trailed off and licked his lips, eyes landing on Bruce's stomach.
“Are you looking inside me?!” Bruce hissed and gave him another smack, using his other hand. He didn't want to actually break anything. The breathless whine it earned him only made him want to do it again. “This hand too, Alpha,” he redirected.
Kal studied his hand, carefully moving his fingers around. “Mm… all good,” he mumbled. The scent of satisfied alpha hung heavy in the air, warm hands moving to settle on his hips. “What’re you doing up there, anyway? Wanna ride?”
Bruce couldn't hold in the laughter that bubbled back up, falling forward to nuzzle under his alpha's chin. “Thought about it,” he mumbled. “Tired.”
“Tired? We have a puppy to make, and you're tired?” Despite the protest, Kal was purring loudly underneath him. “Rest. I'll keep you safe. You and our puppy.”
“No puppy yet, stupid.”
“Bruce,” whispered chidingly against the top of his head, warm arms settling around him, “rest. Got you.”
He believed it. He couldn't not, when he could feel the fierce devotion. He could also feel a hint of tiredness beyond his own. They both needed rest, and probably a good bath. Maybe Alfred will have mercy later and run one later.
“Safe,” he breathed, nosing along his jaw in a lazy scenting.
“Safe.”
