There were three sides to Clark that Bruce got to see in the bedroom.
The first was gentle Clark, Bruce's favorite, the sweet and caring man who just wanted the best for his partner. The second was whiny, desperate Clark, who was so much fun to tease and edge and overstimulate until he dissolved into a fucked out mess.
And then there was mean Clark.
Mean Clark didn't get much of a chance to shine, mainly because Clark normally didn't like being aggressive in bed. He would never let that side show unless Bruce asked for it. The last time mean Clark had reared his head was when he was in rut, and even then, it was all instinct induced rage.
Bruce loved it when Clark was a gentleman in bed, and he relished in teasing Clark until he cried. But sometimes, he just needed Clark to be rough.
That was how Bruce ended up here, wandering outside the Fortress of Solitude, wondering what Clark had in store for him.
He'd confided in Clark a couple weeks back that he wanted to see him be rough with him. Clark was a bit confused and worried for Bruce's safety, but after the two talked it out and discussed their boundaries, he came up with an idea. He wouldn't tell Bruce what it was, only that, "I think you might enjoy this."
As Bruce wandered up to the entrance of the fortress, he started to wonder why he hadn't seen Clark yet. Normally, he'd greet Bruce right there, so the lack of his presence was unusual.
The soft crunch of snow behind Bruce made him turn around. He was expecting to greet Clark, only to feel something shoved over his mouth. The figure before him gripped him tightly with python strength, refusing to let go. Bruce's angry shouts were muffled by the cloth over his mouth and nose, but eventually got softer and quieter. His whole head felt like he was swimming, his mind going blank as drowsiness overtook him. The last thing he could remember was a voice whispering, "Shhhh, just let go, that's it," as he blacked out.
🛸🛸🛸
Bruce woke up to piercing cold and blinding white light.
He felt as if he was recovering from a bad hangover. The world around him spun like a top as he came to. The ground beneath him felt ice cold, and his back and arms hurt like hell. The cold air bit against his naked skin - since when had he gone naked? He could only assume that his captor had stripped him down.
It took Bruce a moment to realize that 1.) he was currently contained in a cage with seemingly no lock, just bars, 2.) he had cuffs around his wrists, which were bound above his head, and 3.) there was some sort of collar around his neck, attached to a chain which led out of his cage.
"What the hell," Bruce slurred. "Where..."
Bruce looked out of the bars of his cage to see a man sitting in front of him, dressed in a navy blue suit with a high gold collar, with an elaborately woven red and gold cape draped over his shoulders and back. A golden coronet rested on his brow, and a myriad of elegant rings decorated his fingers. He held in one hand the chain attached to Bruce's collar.
Bruce knew this could only be one person.
"Oh, look, you're awake," Clark said, his voice lower and more sultry than usual.
"What the hell is this?" Bruce demanded. "The fuck do you think you're doing?"
"Temper, temper," Clark said. He lightly tugged on Bruce's chain, and Bruce pulled back, trying to fight his restraints.
"What do you want with me?!" Bruce snapped. "What the hell am I doing here?"
"Really?" Clark said, raising an eyebrow. "You, a human, intrude on Kryptonian territory, my territory, try to enter a protected fortress without proper clearance, and you expect me to let you go? You expect me to be nice? Insufferable, I swear."
Bruce glared at him incredulously. "Clark, what the hell are you- hggk!"
His sentence got cut off as Clark sharply tugged on the chain, choking him for a moment.
"My name is Kal-El, human," his captor snarled between gritted teeth. "Though you will address me as master."
Bruce could feel arousal begin to stir within his belly, but he hid it with a derisive laugh.
"Master? Are you serious?" he scoffed. "Do you know who I am?"
"Yes, I do," Kal-El said coolly. "You're a human invading the territory of the House of El, and by Kryptonian law, that makes you my property."
The way he said it so plainly stunned Bruce. He sounded so confident that he'd be able to keep Bruce as his property.
Alright, Bruce thought. Let's see what you have planned.
"What makes you think I'm your pet?" he challenged. "You can't keep me here forever."
"On the contrary, human," Kal-El said matter of factly. "You're going to stay here as long as I want you. And don't worry, you're going to make a fine pet. You just need a little training."
Bruce gulped as Kal-El got up from his chair. His captor must've seen the worry in his eyes, because he said, "You're lucky I was the one who found you. If any of the patrol had captured you first... well. Let's just say that normally, little intruders like yourself would be passed around among the soldiers. I don't feel like sharing you anytime soon."
An image popped into Bruce's head of him getting fucked by a whole legion of Clarks, and he prayed that Kal-El wouldn't see the blush on his face. If he did see it, he didn't say anything as he he knelt down by the cage. He reached one arm through the bars, and Bruce watched him warily.
"Now, let's see what I'm working with here," Kal-El muttered. "Oh, and don't try to bite. I don't want to have to muzzle you."
Bruce could tell by the tone of his voice that he was dead serious, so he had to stay still as Kal-El grabbed him by the jaw and tilted his head in different directions, inspecting him like some sort of prize horse.
"You look like you come from a good pedigree," Kal-El said quietly. "You must've been a warrior of some sort back on your homeworld."
Bruce's heart fluttered at the veiled praise for a brief moment. Kal-El pulled his arm back from the cage and returned to his chair.
"Fortunately, that doesn't matter anymore," he said nonchalantly. "You now get to begin your new life as my pet, and I think it's time we get started with your training."
Kal-El reached for a controller and continued, "I'm going to release you from your binds. Do as I tell you, and I'll reward you. If you disobey me, I'll have to punish you, and neither of us want that. Understand?"
"Yes," Bruce said with a nod. Kal-El raised an eyebrow.
"Yes what?" he said expectantly. Bruce swallowed back his pride.
"Yes, master," he said quietly.
"Good," Kal-El said. "Now."
He clicked a button on the controller, and the cuffs opened up, letting Bruce fall back against the cage bars. He sat up straight and rubbed his wrists, grateful to finally be free.
"Let's start with the basics," Kal-El said. "All fours."
Bruce pushed aside his embarrassment as he got down on his hands and knees, the cold metal chilling his palms.
"Very good," Kal-El said. "Sit."
Bruce sat like a dog, trying to ignore how cold everything felt on his skin. He knew that his best way out of this was to play along with Kal-El's games, but dammit if they weren't degrading.
"See, that's not too hard, is it?" Kal-El cooed. "You're already doing so well."
Bruce wanted to smile at the praise, but he kept his stone-faced demeanor as best he could. Kal-El picked up the controller from his desk and clicked another button. One of the sides of the cage slid up, giving Bruce a way out.
Kal-El crooked his finger and said, "Come here." Bruce jerked his head backwards, drawing the chain taut. Kal-El glared at Bruce with a curled lip.
"I said come here," he said lowly, "unless you want to get punished."
Bruce gritted his teeth in frustration, but eventually gave in and crawled on all fours towards his captor.
"There we go," Kal-El said. "Sit."
Bruce sat back down, and Kal-El leaned back in his chair, giving Bruce a look of fascination.
"Now," he said, "I know that if there's one thing you humans lack, it's patience. You may have gotten everything you want back on your homeworld, but here, you're going to have to wait to get what you want. I think it's time I teach you that."
He turned his chair around to reach the desk behind him. Bruce hadn't noticed it at first, but Kal-El had a variety of toys displayed behind him, including the muzzle he'd mentioned earlier. Bruce's eyes widened as he realized where this might be going.
"Wait," Bruce stammered, "what are you-"
"I didn't say you could talk, did I?" Kal-El asked. When Bruce closed his mouth, he continued, "You didn't think I was just going to train you for companionship like one of your Earth dogs? No, you're a special kind of pet. You're here to serve me in any way I so choose." He leaned down to cup Bruce's face in his hand and said, "You should feel honored. You're a luxury among my people, and such a pretty one at that..."
Bruce couldn't tear his eyes away from Kal-El's impossibly blue gaze. He leaned his head into his master's touch, and Kal-El chuckled a little before pulling away.
"That being said," he continued, "you're still in need of training. I might as well have a little fun with it."
He undid his golden belt and slid his pants down to his knees. Bruce realized, much to his surprise and arousal, that Kal-El didn't have anything on underneath, letting him get a perfect view of his slit. Bruce gulped as he saw Kal-El run a finger up his slit, which slowly opened before him like a blossoming flower, revealing his already wet cloaca.
"You like what you see, don't you?" Kal-El said with a sly grin. "You humans, always so fascinated by the forbidden. It's almost endearing."
Bruce started to crawl towards him, but his master shot him a dark look.
"Now now," he said patronizingly, "you're going to have to be patient. Stay."
Bruce backed up and sat down, watching as Kal-El slid one finger inside himself, then two. He couldn't look away as his master pumped his fingers in and out, stretching himself open. Bruce could feel his cock throbbing as Kal-El spread his legs a bit wider, giving him a better view.
Kal-El reached behind him on the desk and grabbed a vibrator - the same one, Bruce realized, as the one he'd used to experiment on Clark back at the batcave. Turning it on and setting it to a low speed, Kal-El ever so slowly guided it inside himself, letting out a long, throaty groan of satisfaction as it filled him. Bruce felt himself start to drool as he saw Kal-El's hole stretch around the vibrator, wishing that he was the one opening him up like that.
Watching Kal-El begin to slide the toy in and out of himself, throwing his head back and moaning loudly, Bruce felt his cock growing painfully hard. He bent over on his hands and knees and reached down to wrap his hand around his aching cock. He squeezed his eyes shut and gritted his teeth as he jerked himself off, listening to the sounds of his master fucking himself with the vibrator. He was so close, he might come at any moment-
"Did I tell you that you could get off?"
Bruce froze. His eyes flew open, and he slowly raised his head to see that Kal-El had stopped using the toy and was now glaring at him with disdain.
"Well?" he said. "Did I?"
Bruce shook his head slowly, and Kal-El growled, "Use your words."
"No, master," Bruce whined. Kal-El tutted in disappointment.
"Disgusting," he sneered. "And you were doing so well, too... I hope you know this means I'll have to punish you."
Bruce shrank in on himself and murmured, "Yes, master." For a moment, he thought, He's not gonna let me come, is he?
Kal-El squinted at Bruce, then turned the toy off and set it back on the table.
"You know what?" he said. "I'll give you what you want. If you need to get off so badly, then here."
Bruce tilted his head in confusion as Kal-El crossed one leg over the other, sticking out one gilded boot, pointed straight at Bruce's face.
"Well, go on," he said. "This is all you'll be getting until I decide you've been punished enough. Be grateful I'm letting you have this much."
Bruce felt a sinking feeling in his gut as Kal-El yanked hard on his leash, forcing him to crawl forward. Kal-El set his boot on the ground before Bruce, and the smaller man tried his best to straddle it. He went to hold onto Kal-El's thigh, but his master slapped his hand away.
"No touching until I say so," he ordered.
"Yes master," Bruce whimpered. His whole face turned beet red as he rocked his hips back and forth, humping Kal-El's leg, desperate for any sort of friction. The feeling of the cold leather against his dick felt so bizarre, but Bruce would take what he could get at this point. He knew he wouldn't last long, not at this rate.
"Look at you, getting off by fucking my boot," Kal-El said, disappointment lacing his voice. "Are all of you humans this sex addled, or are you just the exception?"
Bruce didn't have an answer as he rutted against his master's boot, chasing his orgasm until finally, he came in spurts all over the leather. He stayed there on his hands and knees, panting as he came down from his high, until Kal-El spoke again.
"We're not done here," he said. "I'm not going to walk around with your come all over my boot. Clean it up."
Bruce couldn't believe Kal-El's audacity, but his sneer made his intentions very clear. He bent down to lick the come off of Kal-El's boot, finding that this was only making him get hard again, much to his horror.
It took a minute or two to get it all off, but once he did, Kal-El lifted his boot off the ground to examine Bruce's handiwork.
"Looks good to me," he said. "You took your punishment well. Now, what do we say after a punishment?"
Bruce didn't know what to say, but he could wager a guess.
"Thank you, master," he offered. Kal-El smiled and reached down to pet Bruce's hair.
"Very good, I didn't even have to teach you that," he crooned. "Good boy, such a good little pet."
Bruce felt a giddy smile stretch across his lips as he leaned into his master's touch. Kal-El scratched Bruce's scalp, sending delightful little shivers down his spine.
"I think it's time you get your reward," he said, "a treat for being such a good boy."
Bruce's eyes widened with excitement as Kal-El spread his legs and used his fingers to part his opening. Bruce's mouth watered at the sight of his master's cloaca gushing with wetness.
"You'll have to use your words to get your treat," Kal-El said. "Beg for it."
The floodgates in Bruce's brain burst open as he stammered, "Please, master, let me eat you out, I've gotta taste you, you look so fucking wet, please please please let me eat you out-"
Kal-El chuckled and said, "Alright, boy, that's good." He patted his thigh and instructed, "Hands up here so I know you're not touching yourself again."
Bruce put one hand on each of Kal-El's thighs as he eagerly waited for the green light. Kal-El nodded once, and Bruce dove in for his reward. There was no technique or finesse in his ministrations, just him eagerly lapping at Kal-El's cloaca and drinking in his fluids. His lips and tongue worked at his master's hole with a desperate sort of need. He slid his tongue as far inside of Kal-El as he could, and was rewarded with a satisfied groan.
"Oh, Rao, keep doing that," Kal-El said in a breathy moan. "Your mouth feels so much better than any toy..."
Eager to please his master, Bruce tonguefucked him as best he could, drinking him up like the finest ambrosia. He could feel Kal-El's thighs tensing beneath his hands and knew he was close. As Bruce doubled his efforts, wracked with the desire to make his master come, Kal-El grabbed Bruce by the back of his head and shoved his face further between his legs, letting out a loud cry as he came all over Bruce's face.
"Thank you, pet, your mouth feels amazing," Kal-El said, his voice slightly hoarse. "You're such a good boy..."
"Thank you, master," Bruce said as Kal-El let go of his head. He got up and started to turn around so his master could fuck him, but stopped when he asked, "What are you doing?"
"...I thought you wanted to fuck me, master," Bruce said. "Isn't that why I'm here?"
"Oh, my sweet little pet," Kal-El tutted, shaking his head, "you're here to service me however I see fit. and right now, I want you here." He slid two fingers inside his cloaca, scissoring himself open. Bruce couldn't come up with anything to say, unable to spit out anything but an awkward stutter.
"Don't play dumb with me," Kal-El said, "I know you enjoyed watching me playing with myself. I saw how hard you got watching me fuck myself. I know how badly you need to stretch me open with your cock, you poor little thing. Is that what you want, pet? You want to fuck me as hard as you can, stretch me wider than any toy? Well, I'll let you since you've been such a good boy. I'll even let you come inside me if you want. But first, I want to hear you beg."
Bruce couldn't hide his desperation as he pleaded, "Master, please, you gotta let me fuck you, I wanna fuck you so bad! I wanna make you feel good! I gotta come so bad, please, master, let me come inside you-!!"
"There's a good boy," Kal-el cooed. "Now, go on. Fuck your master."
Bruce eagerly stood up and braced himself on the back of his chair as he pushed his way into Kal-El's tight, wet heat. A high gasp escaped Kal-El's lips, followed by a laugh.
"Mmm, you feel so big, pet," he said, sounding almost proud. "You're stretching me so well, you're so deep inside me..."
The praise made Bruce whine like a puppy as he started rocking his hips, fucking Kal-El with reckless abandon, the only thing on his mind being a frantic need for more, more, more. Kal-El was oh so wonderfully tight, and the shameless noises he was making only spurred Bruce on even more. He buried his forehead in the crook of his master's neck, panting and crying from the overstimulation.
"That's it, pet, good boy," Kal-El tried to speak with a level voice, but his arousal made him falter. "You're fucking me so well, your big cock feels so good! Come for your master, pet, come inside me!!"
Everything was too much for Bruce, and with a loud wail, he sank himself in to the hilt as he came, his hips stuttering with his final few thrusts as he emptied his balls inside his master. It didn't take very long for him to feel Kal-El tighten around him as he came, his head thrown back in a silent scream.
Bruce rested his head on Kal-El's shoulder, his cock still buried deep within him. Kal-El rubbed his pet's back with one hand and carded his fingers through Bruce's hair with the other, crooning softly to him.
"Shhhh, there you go, that's it," he said quietly. "Good boy, such a perfect little pet. I've trained you so well, you've done such a good job."
Bruce leaned back so he could look his master in the eye, then leaned in to kiss him. Kal-El chuckled into the kiss, continuing to pet Bruce's hair.
"Here, on my lap," Kal-El said, patting his thigh. Bruce got up to readjust himself, pulling his softening cock out of Kal-El's cloaca with a wet squelch. Bruce felt his face heat up as he watched his own come start to slide out of his master's hole.
"Oh, look at that," Kal-El said proudly. "Look at how much you came, pet. You filled me up so well..." He reached down and started to scoop up Bruce's come and push it deeper inside of him, which made the heat in Bruce's belly start to simmer again.
Kal-El hooked his arm underneath Bruce's legs and pulled him up into his lap, holding his pet close as he pet his hair, whispering his praises. Bruce rested his head on Kal-El's chest, listening to his slow, steady heartbeat.
"Thank you, master," Bruce slurred, feeling himself growing sleepy in his post sex stupor.
He knew that, when the morning came, he would wake up in a soft bed. He knew that Kal-El would return to being Clark, and Clark would fawn over him as he always did, asking if he was ok, if anything hurt, if he liked the night before. He knew that he would have to reassure his partner that he loved every moment of it, that he needed to stop worrying too much.
But for now, in his fucked out state, Bruce just accepted that he was now an alien's special pet, that he wouldn't have to return to his life fighting crime, that he lived to serve his master.
In that moment, Bruce didn't want anything else in the world.
