Bruce was dripping slick from his omega cunt, already high in heat. He hadn't been able to get away in time from the watchtower filled with the other Justice Lords. And now he feared it was too late, that they would know what was wrong with him, what he had kept secret, both as Lord Batman, and as Bruce Wayne, for years.
Locking himself in his private quarters, and then locking down the entire wing of the satellite he was in was the best he could do, but he feared that even that would not be enough, that Lord Superman, above all, would still be able to smell him, and that nothing would keep the Prime Alpha away from an Omega in heat in his very own territory.
His fears were answered as he felt the first blow of metal and glass shatter and buckle under unstoppable blows, the heavy doors being rendered asunder as the Prime Alpha headed his way.
His heart hammered as his pussy clenched, leaking out more slick. Wrapped in the Blankets of his bed, he felt paralyzed as the door to his personal room was ripped off its hinges, revealing the growling form of Lord Superman.
The looming, furious Alpha stormed into his room, tossing aside furniture and throwing open every closed cabinet and closet door that was in reach, scanning every inch.
“Where are they!?” he screamed, rounding on the huddled form of Bruce wrapped in his Blankets. “Where are you hiding them, Bruce? I KNOW you have an Omega hidden away up here, in the middle of MY territory. Now Where. Are. They.
When Bruce didn’t respond, too overpowered by his own instincts to keep small and quiet in the face of Alpha anger, Kal stalked closer. “You didn’t think you’d get away with this did you? I can smell Omega slick flooding this goddamn room, Bruce. I don’t know why you’ve decided to disrespect me like this, bringing your own Omega in heat to the middle of MY Territory, but this will not go unpunished.
Kal grabbed the Blankets wrapped around Bruce in his makeshift nest, and ripped them off, revealing Batman, dressed in his suit, cornered and alone.
Superman was nearly knocked back by the wave of slick smell that was no longer trapped under the blankets, his anger turning to confusion in an instant. As strong as the smell of fresh Omega cunt, high in heat, was, there should've been an Omega hiding under there. Unless, of course, there was.
Kal really looked at Batman then. While the only skin visible was what the lower part of the cowl revealed, his poster was unmistakable. The hunched over trembling and legs curled up to his center were not the proud stance of a challenging Alpha, but the defensive position of a scared Omega, caught outside its nest in heat.
Kal couldn’t believe it. Batman was one of the toughest Alphas he had ever met. While Omegas weren’t always weak and trembling, they were certainly more vulnerable than Alphas, their instinct to guide and protect rather than conquer and attack. And then of course, when they had their heats, they were nearly mindless, thinking of one thing and one thing only, so much more submissive than an Alpha in Rut.
None of that described the other Justice Lord. Batman was as stubborn as he was vicious. No other Alpha would puff out their chest and challenge Kal the way Bruce would. No one would dare.
But the evidence was nearly inscrutable, and Kal had to be sure. Crawling up onto the bed, he grabbed Batman by the ankle and hauled him out of his curl, bringing the other Lord to stretch out on the mattress in front of him. The Bat-suit was firmly in place, and the thick waterproof material would trap any slick inside, if not the smell. The iron thread weaved into every piece of the suit made looking through it impossible as well.
“No, no.” Bruce said, trying to scramble away. Kal shushed him as he kept a firm grip on his ankle. With his other hand he cupped the hard groin of the Bat-suit, getting a feel for what was behind the cup. It felt like it should, the plastic mold filled by something, but when Kal made eye contact and squeezed, much harder than the cup could protect from pain, Bruce didn’t react at all, still trying to scramble off the bed.
Kal was sure, then. He grabbed the front of the Bat-suit, cup and all, and ripped, barring what was underneath to his hot gaze. The fake Alpha phallus that filled the cup bounced out as it hit the floor, no longer secured in place. The black compression suit and briefs also shredded under the force of Superman's hands, until the wet pink pussy was on full display.
Bruce was not happy about that. He tried desperately to close his legs, shaking his head and whining, but Kal had a grip on both his knees and forced them apart, opening him up for Lord Superman's scrutiny.
‘’How the hell did you hide this, Bruce? And for so long?” Bruce didn’t answer, refused even to meet his gaze, and lowered his hands down around himself, hiding the proof of his omega nature from Kal's gaze.
“Well?” Kal asked again, shaking the other's legs in demand.
“I- I- I just, I just don’t, I just never told anybody, Kal. The only one who knows is Alfred, and my personal Doctor. Even on paperwork, Bruce Wayne is an Alpha!” Bruce said, trying somehow, to make Lord Superman understand. “I couldn't do what I do, Both as Batman and as Bruce Wayne, if people knew! There would constantly be someone trying to control me! You know how it is, for Omegas.”
“I do.” Kal said, tone low and reassuring. Bruce glanced up, eyes full of hope that his fellow Justice Lord would sympathize and help him, but that hope hardened into a stone in his gut when Kal grabbed his hands, already coated in his own slick and pulled them out of the way so he could stare at his dripping hole.
“I know it’s been hard for you Bruce, but you don’t have to worry about anyone trying to control you, ever again. No one would dare. No one would ever dare to tell Lord Superman’s Omega what to do.
“NO!” Bruce shouted, fighting his own instincts, so much more overwhelming while in heat, tooth and nail. When every fiber of his being wanted only to submit to the most powerful Alpha on the planet, and possibly the whole galaxy, he simply couldn't do that. He would lose everything. It might still be in his reach, but it would all belong to Kal-El, as surely as Bruce himself would.
Kal shushed him again, the strong purr issuing from his throat would be reassuring under any other circumstances, and even now he felt his Omega responding to it, calming and quieting his trembles. Kal held his legs open with one hand, and held both his wrist in the other as Bruce thrashed and kicked, desperate to get away while he was still in his right mind enough to do so.
Kal all but ignored his attempts. He brought his face down to Bruce’s core, and inhaled, taking in the strong sweet sexual odor of his leaking slick. Bruce felt embarrassment, burning hot, crawling up his spine, but that was nothing compared to the feeling when Kal lent further down and licked him, hole to clit, with his wide flat tongue.
Bruce gave a breathless shout as Kal continued his ministrations, licking the slick out of him as fast as he body produced it. His desperate thrashing turned to uncontrollable wiggles as his guts heated and clenched tighter and tighter. He had only done this to other people before, never been on the receiving end of it, and he had no way to deal with the sensations blazing through him.
When Kal introduced a finger into his clenching pussy, he came, squirting Kal in his cum and drenching the Alphas face.
Bruce lay there, mind nearly empty as he panted and shook. Kal finally lifted off him, but only to tear away more of the Bat-suit, revealing his chest and stomach all the way down to his thighs, then reaching up and removing the cowl completely, ignoring the electric shock.
When Kal pushed down his own suit and underwear, letting the massive Alpha cock spring free, the panic brought Bruce crashing back to reality. He whimpered and closed his legs, going back into his defensive curl.
“Not this again.” Kal said, grabbing him, again, by the ankle and bringing him back to the foot of the bed. “Aren’t you in heat? You should be begging for me, not hiding from me.”
“Please Kal! I’ve never- I can’t take that, you’ll break me!” Bruce said, unable to rip his eyes off the swaying member.
“Don't lie, Bruce. I worked at a newspaper, for god's sake, I know all about your escapades.”
Bruce shook his head in denial,”No-no, I only took other Omegas home, and then only ever ate them out. I never let anybody really see me, remember? I Couldn’t keep up the pretense of being an Alpha if word got out someone had fucked me, could I?”
Kal looked at him, incredulous. “So are you really trying to tell me you're a virgin, Bruce.”
Bruce nodded his head. The only thing that he had ever had inside his hole had been the knotting dildos that he used to help him through his heat, and even then he had never graduated from the small, nearly beta sized ones that had little walnut sized knots that were given to Omegas during their first heat, before they had finished growing yet. He had always found them to be perfectly usable, if not entirely satisfactory.
Kal was much, much bigger than that. Alphas were huge, and he put other Alphas to shame. But instead of understanding and backing off, his admission seemed to light a fire under Kal. He fit two fingers back inside, and scissored them, feeling the tight opening struggle to stretch around him. His eyes darkened as he realized Bruce was telling the truth, his little pussy almost too tight for even two fingers.
Bruce was fighting his heat haze, the tide trying to bring him under, as much to protect his mind from the unwanted matting as it was to follow its natural instinct to submit to his established pack’s prime Alpha. But Bruce wouldn’t let it, he fought to remain aware of what was happening, even as his body betrayed him, his cunt gushing with slick, and starting to soften and stretch around the fingers prying him open.
He kept his whimpers, once of fear, now of overwhelming want, trapped in his throat as he was finally stretched enough for a third finger, then a fourth. Kal had latched his mouth around Bruce’s nipple, sucking and biting it like he wanted milk. A reminder of what would come, once Kal had his way.
Once Kal could move his fingers inside of Bruce a little more freely, he reared up, laying his massive cock along the omegas front, measuring himself against the body beneath him.
Bruce couldn't stop the high distressed warble from leaving his mouth, looking at it. Like this, the head went past his belly button, for god's sake!
Kal’s chest vibrated with a deep Alpha rumble, the kind that nice, respectable Alphas make when they were trying to reassure their mates, as he stroked along Bruce's skin just to the side of where his cock lay.
“Don’t worry Bruce, you can take all of me, physically.”
“The hell I can, Kal. You're gonna be in my lungs, goddammit!”
Kal laughed at him, in a mockery of shared mirth. “No I won’t Bruce, see?” he said as circled a spot just under the head of his cock. “Right here’s the opening to your womb, which is nice and open for me while you're in heat, just enough room to pop my head in.”
Bruce felt embarrassment like he never known when he realized that Clark was using his X-ray on him, measuring out his vagina and insides to a millimeter, seeing him in a way no one ever should.
He didn’t have long for the shame to settle before Kal was moving back, lining himself up.
“Kal,” Bruce tried, one more time, “Kal, Please, Don't do this, I’m already in your pack, you don’t have to breed me too.”
Kal smiled down at him, the very picture of a handsome benevolent god. “Bruce, everything on this planet was made for me to rule, sweetheart, and that includes you. I didn’t know just what I had been gifted until now, but now that I do know, I”ll never give you up. You were made to be my Omega, Bruce, to carry my litter. Between your mind, and my powers, our pups are going to be the most powerful thing in this universe. And it’s your job to help with that.”
Bruce didn’t have words for the feelings that swirled in him as Kal told him this, and any thoughts he did have were firmly knocked out of him as Kal pushed in, the fat head of his dick pressing down hard on his opening, before finally, with a wet pop, punching in. The whimpers and shouts he had kept locked away came pouring out as his legs spassamed.
Kal grunted above him. He leaned down to Bruce’s neck and started to lick over his mating gland, getting it wet before he laid down the bite that would claim him as he was knotted later. Slowly, he pushed more and more of himself inside, until only his soft knot was still out. The head of his dick had found the half open entrance to Bruce's womb, and kissed it softly with every small thrust.
Bruce was overcome, nothing had ever felt like this, like too much and not enough wrapped in one. His opening felt like it would break if it had to stretch another millimeter, but his Omega still screamed to be knotted. Bruce didn’t know what he wanted. All he could do was lay there, anyway. His legs no longer listened to his commands to kick, instead planting themselves against the bed and opening as wide as they could to accommodate the cock moving inside him. His hands would no longer push Kal away, instead they were tangled in his hair and around the back of his neck keeping him in place as he lapped at his gland.
The noises falling out his throat were pure Omega, warbles and whines of adoration as he was fucked, completely against his will. The spit running out his open mouth nearly as copious as the slick squirting of his pussy every time Kal shoved back in, his thrust getting harder and harder.
Kal’s mouth left his neck as leaned up to watch himself disappear in the warm snatch, and Bruce’s skin flushed again as the tell-tell shine of x-ray vision lit up Kal’s eyes. Kal was watching as his Cock plundered previously untouched depths, even though it still had not breached the waiting womb. Instead something else caught his eyes, his fingers coming to press down on Bruce's stomach, just under his belly button.
Bruce realized, with horror, what Kal was after as he felt his bladder compress, and Kal shifted his entire position, hauling him up with one hand and changing his angle so that the head of he dick battered into the sides of his reservoir.
Bruce strained and bit down, trying in vain to clench down and hold it, but the dual sensations of pressure form top and bottom were two much, and with a scream he pissed himself, the liquid gushing out along with a new torrent of slick. Kal laughed in triumph as he laid Bruce back down into the puddle. Proud he had made the mighty Batman piss his own sheets.
The mess only seemed to excite him more, the stink of Omega urine so alluring with heat pheromones. He pounded faster, always careful to stop right before the small hole in the back.
Bruce was nearly dissociating, the shame and need rendering him nearly catatonic, when he felt new pressure inside him. Roused from his state, he looked down into the glowing x-ray eyes of his New Alpha, fixed on the spot where he had pointed out his womb earlier. Slowly, so slowly, Kal pushed his cock in, deeper than before. Watching as the small opening stretched wider and wider around the blunt head.
Bruce could feel it, like nothing he had ever felt before. Wrong and so so right. A pull so deep, both physically and mentally, that it made fresh tears pour from his eyes. Kal was entranced by the sight, once the opening had stretched around the fattest part of his head, soft and clinging, he pushed the rest in in one go, causing Bruce to whine.
Then back out, all the way out of the sopping wet cunt altogether, before slamming back in with all the force he dared use on a human, his blunt cock head slamming back into Bruce’s pussy hole, through his whole channel and past the little womb hole to smack into the back wall of it, as tight a fit as was possible.
Bruce screamed, everything but his shoulder, head and feet leaving the bed as he arched nearly into a perfect C, staying locked like that as Kal thrust in and out, again and again.
Bruce was crying when Kal finally slowed down to a more sedate pace, no less deep, but much more gentle and shallow. Through his thick sobs and moans Kal rubbed his stomach, purring like a lion as he lowered his hips back onto the bed.
Bruce knew it was almost over, he could feel the hole of his cunt stretching impossibly wider around Kal’s knot as he fucked him with it. When it started to really hurt as it went in and out, Bruce tried to bear down on it, keeping it in before it started to do damage, but Kal didn't let him.
He rocked his hips back, bringing his knot out of the squelching hole, then back in, so forcefully that there was no other option but to admit entrance, even after the point where it should be to big to enter.
“Beg me.” Kal said, looking into the pained and panicked eyes of Bruce. “Beg me to Knot you.” he was still moving his hips, near tearing the too tight hole.
Please, god! Kal! Stop! Knot me! Knot me, and don’t pull back out, Please!” Bruce cried, so far past the point of pride that shame was a distant memory.
With a growl, Kal did just that, snapping his knot past the abused and swollen orifice, slamming his dick home into the tight sheath and womb.
Warmth started pumping into Bruce immediately, so much hotter and so much more than human Alphas, that even Bruce felt it through the searing pressure of his hole gaping wide, then swelling closed once the Knot was lodged inside him. All of that was forgotten though, when his neck and mating gland were pierced deeply by Prime Alpha Fangs, forever scarring him with their mark.
Every muscle in his body pulled tight as electricity arched from his claimed mating gland, down his spine and into his rigid cunt, pulsing out an orgasm so intense that everything went black.
When he came to, Kal was rubbing his stomach and licking his bite, soothing, his knot still pulsing inside him. Bruce breathed deeply, glad the worst was over.
“Feeling Better?” Kal whispered into his ear.
Bruce felt like he had been hit by a truck, actually, but answered only a short “Yeah.” in response. Until he had some control back, he was willing to do whatever made Kal happy.
Kal accepted his answer, humming in contentment. Looking down, Bruce could see his belly, swollen to a bump with everything stuffed and caught inside him. Heat infused his middle, partly with how bruised everything was, and partly with Kal’s inhumanly hot cum.
“Christ”. Bruce said, making a face at the bulge in his stomach.
“I know, right. Can't wait till it’s real, till you're stuffed with pups and cum!” Kal said. Looking at it proudly.
You want to make me bigger? It's too much already. Bruce moaned.
“It’s not”, Kal answered, “you can carry so much more. In fact, why don’t we test that now. Kal said, shifting back onto his knees, practically dragging Bruce by his knotted pussy into position, lifting and spreading his legs. His eyes alight with mischief and x-ray.
Can you cum again already? Bruce asked, concerned.
No, not Cum. Clark said. A smirk on his face.
Understanding dawned on Bruce all at once. “Don't you dare!” he shouted.
“Why not? Fairs fair. You pissed on me, I piss on you. Or in you. I guess.”
Bruce canted his hips to get away, but succeeded only in pulling against the filled knot which wasn’t moving an inch. Too late anyway, he felt new heat fill him as Clark groaned, his Dick pulsing and his tongue hanging out his mouth like a dog as he watched his own piss pour into Bruce's already stretched womb, drenching him in Alpha pheromones.
Bruce's stomach swelled even higher at the amount as the thinner fluid raced back up his vagina to gush out around the knot plugging him. Leaking down his back to soak into his hair. It went on forever, Kal keeping him raised as he flooded him with every drop he could, marking him as Lord Superman’s in every savage way.
Bruce shook, the bruises Kal had left around his hips and knees screaming out under the huge hands. The smell of Kryptonian Alpha drowning him. He was utterly disgusted, but the near Rut smell of the piss confused his instincts, making his cunt squeeze out more slick around the cock plugging him.
Kal took this as a sign that he liked it, hitching his hips and rocking Bruce into the soaked bedding under him. Trying to milk one last orgasm from Bruce before his cock deflated. The liquid churning inside him and splattering out every time Kal moved adding to the mess under him.
Bruce fought it back, now wanting to give Kal the satisfaction, but the heat was building again, and his poor abused Omega was screaming at him to just give Kal what he wanted, to clench and cum around the huge shaft inside him, so that it would find it’s own satisfaction is his body and leave him be after.
Bruce couldn’t fight it anymore, his tired body giving over to one more small squirt of cum around the big Alpha. Kal groaned above him, his cock pulsing anew with a fresh wave of spend for his body to take.
Bruce expected to be put back down now, to be allowed to rest until the baseball sized intrusion inside him shrunk enough to pop back out, at least, but instead his legs were raised higher, putting all his weight on his shoulders and neck as Kal placed his knees on his own shoulders, the front of his body flush to the back of Bruce's. His heavy rod was still buried in Bruce’s gushing slit, pointing straight down toward the bed inside him. Now that Bruce was nearly vertically upside down, all that trapped piss and cum stayed neatly inside, right where Kal wanted it.
Bruce wanted to Kill him. There was no reason to do this, if Kal’s spend didn’t take, then there was something wrong with one of them. He had already pumped more Cum into him in an hour than Human Alphas made in a week. This was just Kal putting him in his place again.
He snarled up at his Pack Leader, and tried kicking Kal in the head, as much good as it would do him. Kal caught his foot and kissed the arch, before laying it back down on his collarbone.
They stayed like that long enough for Bruce's neck to start twinging at him, even as felt some of the pressure buried inside start to lessen as Kal's cock and knot started to soften. Kal gave one curious pull, seeing how much give there was to Bruce’s swollen cunt, before gently laying him back down, then sharply thrusting his hips back, dislodging the half deflated knot in one go.
Bruce had been expecting it, but still the sting of his departure made a sheen of tears coat his eyes anew. The wave of liquids that flowed from his gaping hole made it all the worse.
Kal patted his stomach, and leaned over to sniff into his open crotch before Bruce slammed his legs together, blocking the Alphas face.
“Not gonna let me clean you up?” Kal asked, like that was a completely reasonable thing to do. He opened his mouth and licked his lips, for good measure.
“No!” Bruce screamed, angry as he had ever been with the Justice Lords leader. His new mated Alpha. Tears flowed down his face as he felt his own defeat. There was no going back now. Even if there were Laws protecting Omega’s from unwanted matting’s, Human Laws meant nothing to the Justice Lords, and Kal was the one over all. The only laws that mattered were the ones he made.
Kal gathered him up, lifting him out of the soiled bed. Bruce didn’t fight back, just went limp and unresponsive as Kal carried him into the bathroom, then the shower as he gently cleaned the Omega’s skin and shampooed his hair.
Once they were clean and dry, Bruce was brought to the Prime Alpha’s quarters and bed, where he was tucked in and spooned from behind.
The tears had given away to exhaustion, his heat satisfied by the breeding, and his body so sore that he could hardly move.
He was at the cusp of sleep when Kal spoke behind him. “I won’t be that rough next time, Bruce. I just had to make a point this time, you know that. I just had to make sure you knew who you belonged to.”
Bruce shivered, but said nothing.
“Next time,” Kal continued, “next time, you’ll be pregnant with our pups, and I’ll love you so sweet that you’ll forget all about today, yeah? I’ll fuck you so slow you’ll be begging for more, then i’ll play with your little clit until your begging me to stop. I know I ignored it, today, misbehaving Omega’s don’t get their clit played with, but next time, it'll be the star of the show,
yeah?”
Bruce nodded, giving Kal what he wanted. Kal hummed happily into his neck.”I can’t wait to see our pups, Bruce. They're going to be the smartest, most powerful thing in the galaxy. They're going to help me finally wipe out Darkseid, Apokolips, and anything else that threatens us. They're going to be perfect, Bruce.”
Bruce’s breath caught in his throat. That was the one thing that might make all this worth it. Kal’s powerful Kryptonian DNA, fused with his own. Under his power as much as Kal’s. A power he could use to remake Gotham, and the world into a more perfect state, and that was just the start. As soon as Kal had said it earlier, he knew it was true. Their children wouldn’t just rule the world, They would rule the Galaxy.
Bruce’s whole mind and body settled with the thought. He relaxed back into the arms holding him, wiggling in closer to his mate as he rubbed his stomach, thinking of the future.
