If I'm being honest, these are a little longer than I'd originally intended...think I'll be trying to keep the chapters shorter from now on, perhaps with some exceptions every now and then, because yeah, wow, very long chapters. The last one was an exception I guess since it was special for Hunk's birthday. Hm.

If someone asked Shiro what his favorite color was, he would probably always give a different answer—mainly because he didn't bother spending time to form a firm opinion on something like a favorite color. Sometimes it was black simply to match his aesthetic and other times it was green just to make Pidge happy. Right now, though, there was only one color on Shiro's mind—red.

The color looked so perfect as it tinted the pale skin of Keith's ass, multiple handprints clumping together until they formed a singular massive red bruise, and the sound of Keith's shaky cries resonating within his throat was just the cherry on top.

"Shiro..." Keith tried looking back at him, only to be met with another harsh smack to the ass, and fuck, the way his entire back arched in response had Shiro's cock leaping in his pants, ready to be inside of him.

"What did I say? No turning around. Now, have you learned your lesson yet? Are you gonna start getting along with the rest of the team?"

Keith was trembling and clawing at the bed, head lowered at Shiro's reprimanding. "Y-yes...Shiro, I'm sorr—ah!"

"Liar." Shiro grunted, paddling his ass with his palm and relishing in the adorable yelp that escaped Keith's mouth. "You always say you've learned your lesson, but your constant fighting with Lance puts our missions in jeopardy. I'm going to make sure the lesson sinks in, this time."

"Shiro...I can be good...I can—!" Keith buried his face into the mattress to muffle his cries as Shiro spanked him again, letting his hand rest against his ass, massaging it and feeling up the stinging heat.

"Remember how you promised to be good before the mission? And you still ended up arguing?"

Keith turned to Shiro with tears in his eyes. "But it's not my—ah!"

Shiro smacked his ass without remorse, adrenaline rushing through him at how much he was getting to punish his boy. "No turning around, remember?"

A violent shudder traveled up Keith's body before the boy nodded, pressing his head into the mattress more, probably in an attempt to regain control of his crying. "It...it isn't my fault...it's his fault...he's the one who starts it..."

Shiro dragged his thumb down Keith's crack distractedly, spreading his cheeks open to reveal his pulsing pink hole. "That may be true, but you're at fault for responding to him. You have to learn your lesson; after all, it isn't like I can discipline him."

The thought of disciplining Lance had Shiro swallowing; good god, he could just imagine the tawny round of Lance's ass turning crimson beneath the assault of his hand. He could just imagine the way he would cry out in an even higher voice than Keith, begging for mercy at the hands of his normally calm leader. Punishing Lance would be a luxury...not to mention it would help him tackle the other half of the team's issues...but alas, they didn't have that type of relationship, so all the punishment fell onto Keith.

Keith looked back again as the prolonged silence carried on, eyeing Shiro with a glimmer of hope that only existed to be torn away as Shiro took his prosthetic hand and smacked it into Keith's ass, earning him a bloodcurdling wail of torment.

"I said. Don't. Turn. Around."

"...'m sorry..." Keith whimpered into the bed, instinctively raising his rump for Shiro in a plead for forgiveness, just like he'd been taught to do.

That simple gesture had Shiro's breath catching in his throat, and suddenly he couldn't keep his pants on any longer. Pride and lust clouded his vision completely, and as soon as his massive cock was free and poking Keith's backside, he reached for the bottle of lube that was already on the bedside table, because as per his orders, Keith always kept his lube nearby in case Shiro came in and wanted to fuck him.

"Change of plans. Since you want to turn around so much, go ahead and do it. Why don't you finger yourself for me?"

Keith eagerly turned onto his back to face Shiro as he drenched his fingers in lube before proceeding to jam those fingers up his ass, showing no signs of an understanding for the term 'slow and steady'. It was times like this that proved that Keith would never stop loving Shiro or the things he did to him, no matter how rough their spanking sessions could get.

"Shiro..." Keith moaned, already thrusting three fingers in and out of his ass with curved knuckles.

"You're needy today." Shiro chuckled, liquid desire dripping from his voice as he rubbed the slick lube up and down his thick cock. He was more than ready to split his hole wide open, but the passion on Keith's face gave him another idea.

He sat down next to Keith, twisting his hands around his tip like it was a well-oiled machine. "Come here, ride my cock and you can redeem yourself for being such a bad boy."

Keith didn't need to hear another word; his fingers were immediately out of him as he climbed Shiro and crouched just above his cock, reaching down to massage it with his hands while his own cock pointed towards Shiro. Then, never being the type to enjoy being teased, Keith lowered himself until the proud head of Shiro's large cock was stretching the rings of his entrance.

"Oh god...Shiro..." Keith's hands tightened their grip on his broad shoulders as he continued lowering himself with nonexistent patience.

If it was anyone else, Shiro would've cautioned them to slow down, but he knew Keith, and he knew that the boy didn't care. He just wanted Shiro's cock inside of him, and once that was done, then he would worry about adjusting. There was no use teaching him how to go slow. The most he could do was smash their lips together to occupy Keith so that he had some form of distraction while he took Shiro's cock deeper and deeper.

It didn't take long until Keith was sitting on his balls, grinding down against them, as if forcing himself to get used to the massive size. Shiro could only groan and massage Keith's sides with pride; he was so proud of how well Keith could take him. No matter how many times he fucked his boy, he knew he would never be able to immediately adjust to how tight his small little hole was, and Keith would never be able to immediately adjust to his monstrous size, but they did their best.

"Shiro...oh god Shiro..." Keith moaned, repeating his name like a mantra as he flexed his legs to lift himself up.

"Why're you in such a rush today?" Shiro chuckled, finding it more amusing than anything as he ran his hand down Keith's slender back, watching and feeling him begin to move up and down his cock. No sight was more beautiful to Shiro than the sight of Keith's small body effortlessly swallowing his thickness whole.

"So big...I can feel it stretching me open..." Keith whimpered, leaning his head against Shiro's shoulder as he made sounds that were only for his ears.

It was clear that Keith was still in pain, having not given himself enough time to adjust, but that was part of the reason the other boy was making such satisfied noises.

"Such a slut," Shiro taunted, jerking his hips up and salivating at the way Keith's entire body twisted in pleasured pain. "Such a cock slut. You don't care if your body is in pain or in heaven, so long as it has a big cock inside of it. Is that right?"

Keith keened at Shiro's dirty talk—only they could bring out this side of each other. Between all his moaning and panting, though, he managed to shake his head.

"N-no...not just any big cock...your big cock, Sh-shiro..."

Shiro grinned at that, grooming Keith's hair a bit before leaning back on his hands to let him ride him. "That's right. My big cock. You really are such an obedient boy...is that what this is about? Why you're in such a hurry to fuck yourself on my cock? Are you trying to prove that you can be good for me?"

Keith let out a weeping sound as he began actually moving up and down at a consistent pace, legs shaking his as walls clenched down on his cock each time they stretched. "Yes...oh...for you Shiro...only you...! Ah!" He yelped as Shiro smacked his ass.

"You want to prove yourself? Ride me faster." He bucked his hips up some more, tongue darting out across his lips as Keith moaned and went back to chanting his name over and over again in stupefaction.

His cock was already hitting the deepest nerves in Keith's body due to how quickly things had escalated, sending him into a frenzy of gasps and screams.

"Shh...you have to be quieter," Shiro warned, guiding Keith's face deep into his neck so he could muffle his cries while grinding his prostate against Shiro's fat tip like the hungry slut he was. "That's it...that's my boy...come on, keep going."

Their bodies were a steamy, sweaty mess as Keith resumed riding him with his face buried in Shiro's neck, making things much quieter, but just as passionate.

That quietness was suddenly broken, though, when the door to the room slid open, and Lance stumbled in, rubbing his arm.

"Hey, Shiro...I just wanted to—"

The entire room froze, with Shiro glancing over Keith's shoulder panickedly, wide eyes making contact with Lance's.

All three of their heartbeats could be heard in the dense silence, although Keith seemed less concerned about the situation and more concerned with resuming his pleasure.

"...Lance, I can explain," Shiro started, even though he was sure he most certainly could not explain.

The silence just carried on as he waited for Lance to answer, since he had no clue what to say next. Obviously, Lance didn't have any words, either.

"...Shiro..." Keith moaned in what he probably thought was a whisper, rocking back on his cock a bit, as if telling him to make Lance leave so he could finish.

Lance's face immediately changed color at that from his normal tan to a deep red, and suddenly, Shiro was imagining that color change on Lance's ass. It would look so beautiful tainting his gorgeous, round cheeks...

"I'm sorry...I'll just..." Lance turned to leave, but not before Shiro let out a commanding growl.

"Stop."

Both Lance and Keith stopped what they were doing, as if Shiro's voice affected everyone in the room. A chill shuddered up his spine at the thought of controlling both of these boys.

"Don't leave. Come closer. Now." Shiro barked his last order with emphasis, breaking through Lance's hesitation as the tall boy meekly inched closer to them.

"Sorry sweetie, the situation's changed." Shiro lifted a whining Keith off of his cock, setting him to the side and spreading his legs apart for Lance to get a full view of his massive cock in all its glory. "So, what did you need?"

Lance was rubbing his arm, clearly uncomfortable and self-conscious. "I, uh...well...I was just—"

"Get to the point," Shiro growled.

"Yes, sir..." Lance's face reddened as he let a 'sir' slip out, which in turn made Shiro's cock jump. "I just came to apologize about the mission earlier...I know I made you mad by arguing with Keith...but uh, we can talk later..."

"No." Shiro's eyes scanned his body. "I'm glad you came to talk about that. I can keep Keith under control, but it's time I gave you a lesson, too. Strip."

Lance's eyes jumped out of his eye sockets as he cowered away. "W-wh-what? S-stri—"

"Take your clothes off. All of it. Now. Don't make me wait another second, or I'll be disappointed."

His last point seemed to strike a chord within Lance; Shiro could see his eyes losing their fight, submitting to Shiro's will as he bowed his head and began to strip. It seemed disappointing Shiro was his weak spot.

"Shiro...what's going on?" Keith asked, head leveling a bit now that he didn't have his hole stuffed full of cock.

"I have to give Lance my attention; he needs to be disciplined. You understand, don't you?" Shiro cupped Keith's cheek. "Don't worry, you'll be able to have some fun, I promise."

Keith's eyes wandered from Shiro over to Lance, who had successfully stripped himself save for his boxers, which were already bulging just from the sight of Shiro and Keith fucking.

A small smile plastered itself on Keith's face as he nodded. "Okay, Shiro."

He lightly smacked Keith's cheek in approval before turning to Lance and patting his lap. "Lay your stomach across my legs."

Lance was taken aback by that order, blinking in confusion as Shiro's face lost all sympathy, and he patted his lap harder with a growl.

"I said, lay your stomach across my legs. Now."

His head sunk into his shoulders like a kicked puppy as he slowly came forward onto the bed, shrinking completely under Shiro and Keith's intense glares.

As soon as he was close enough, Shiro yanked him over, shuddering at his yelp and laying him across his stomach. That sound had been everything he had hoped it'd be, and he couldn't wait to hear more...

"Sh-shiro...why are you doing this?" Lance muttered, his voice at a borderline whimper. That would change—Shiro would have him flat out sobbing soon enough.

"Because you need to be taught a lesson. Besides, you're already hard!" His hand reached down to jerk Lance off through his boxers, and Shiro grinned at the way Lance gasped and squirmed at the sudden touching. It was just as Shiro suspected. Lance was just another...

"Slut."

Lance squirmed even more upon hearing that word, arousing Shiro beyond belief. He began rubbing his cock against Lance's back, unable to stop himself from tainting the boy's body with his lust any longer.

"We're gonna discipline you until you learn how to behave, you hear?" Shiro traced his hand down Lance's back, admiring the curve of his lean body almost as much as he admired the shaky moans that escaped Lance's mouth. "Shh...that's it. You're gonna be a good boy for me after this."

He shuddered on Shiro's lap, but made no effort to move away. "Shir—ah!"

Shiro pulled Lance's boxers off in one swift movement, taking in the fruitful sight of his tan ass, completely spotless and unsullied.

"You're gonna be so red, it'll look like your ass is bleeding out," Shiro declared, rubbing his hand over his ass and relishing in how smooth it was. Every inch of Lance's body was so smooth, so pure...

"Oh my god...Shiro..." Lance buried his face in his hands, cheeks already red as he instinctively rose his ass into Shiro's hand, proving that he wanted this.

Shiro was harder than he'd ever thought was possible now; he had fantasized about getting to punish Lance's body before, but to think Lance would actually want it? It was a dream come true.

"Are you ready for this? Ready to be disciplined? We'll make a good, obedient boy out of you." He promised.

Lance swallowed hard, peeking through his hands to turn up to Shiro. "I...I'm not—AH!"

Shiro didn't wait for him to answer as he let his hand crash into Lance's ass, watching in fascination as it shook from its first ever hit, leaving behind a large red handmark.

The boy was already tearing up as he tensed his body against Shiro's, and as soon as he received his second spank, he began struggling to squirm away.

"No moving." Shiro growled, smacking his ass twice in succession, just to make sure the lesson sunk in as Lance paused to cry out in pain.

He leaned down to whisper in Lance's ear while massaging his reddening ass. "Tell me, are you going to be good from now on? Will you behave yourself on missions? Be the good boy I know you can be? Or do I have to teach you how to be good some more?"

Lance was trembling, hands clasped over his mouth. Shiro couldn't blame him—there must've been a massive shock factor in experiencing this side of him for the first time. He couldn't even remember the first time he had begun disciplining Keith like this, so experiencing it all over again with Lance made him throb with excitement.

When ten seconds passed without an answer, he rose his hand once more, chuckling at the way Lance immediately panicked and looked up at him pleadingly.

"N-no! Shiro, wait, yes, I can be good, I'll be—!" He shoved his face into his hands to muffle his cry as Shiro smacked his ass ruthlessly.

"Too late. Guess I'll have to teach you, you naughty boy." He began spanking Lance without pause, giving him no time to plead for mercy or to even catch his breath as the cruel sound of his hand colliding with Lance's ass boomed into the air like gunfire.

"It's so red back here, you wouldn't even believe that your ass could look like this. Come on, let me hear your voice, don't hold back. It's a part of the punishment process," Shiro urged, rubbing Lance's face with one hand while the other continued beating his ass into a pulp.

Naturally, Lance could only hide his cries in his hands for so long, and after Shiro's coaxing, he ended up slamming his forehead into the mattress and letting his screams ring free.

Keith seemed to be enjoying the scene, sitting off to the side obediently with his knees tucked beneath him like a happy puppy. Shiro could almost imagine a tail wagging from behind him. The only problem was his cock, which was completely neglected. That made Shiro frown; he didn't want to neglect his boy.

After he made sure Lance's ass was reddened to the point where he could barely make out its original color, he lifted him from his lap and pushed him in the direction of Keith.

Lance yelped and looked around, as if the spanking had made him delirious. "Wh-what...?"

Shiro propped one leg up on the bed to make himself more comfortable, nodding at Keith. "You two are going to prove to me that you can get along. Go on; get each other off."

Lance's jaw dropped open, and it was clear he was still struggling to keep up as he tried crawling towards Shiro. Keith, on the other hand, was quick to submit to Shiro's orders, hooking his arm around Lance's leg.

"W-wait!" Lance exclaimed, but his useless struggling made it clear that he wasn't fighting back as Keith got on top of him, pausing as red crawled up his face at being in such an intimate predicament with Lance.

Both boys ended up just staring at each other, and for a split second, Shiro sensed some built up sexual tension. It was only a brief flicker of lust in both of their eyes, though, before they grumbled and looked away.

"Keith. Lance," Shiro growled, balling his hand into a threatening fist. "Prove that you can be good boys for me. Make me proud."

They both shrunk back at his scolding, glancing at each other as his orders won out over their pride. Keith was the one who acted first, lowering his cock until it was grinding against Lance's.

"Oh god...!" Lance gasped, arching his back up off the bed.

Keith took that chance to smash their mouths together, and Shiro had never been so proud of him. He and Lance were meshing together perfectly, and it made sense. Sex was the perfect way to get these two horny boys to be obedient.

He didn't even need to give any more orders or threats as the two of them made out and grinded their hips together with a drunken desperation, and it was clear to see that Keith was relishing in being able to feel in power for once.

Sloppy strings of saliva connected their mouths when they finally pulled away from each other, and they spent a few seconds just staring at the other with lust before Keith turned around into a 69 position, shoving his cock down Lance's open mouth while burying his face into Lance's crotch.

Lance's gagging noises were one of the hottest things Shiro had ever heard, but what was even hotter was watching the way he pounded his fists on Keith's ass in an attempt to beg him to give him air before just submitting to it, hands going limp at his sides as he was forced to let Keith abuse his throat.

Shiro couldn't help but wrap a hand around his own cock, leaning back and jerking himself off as the two boys sucked each other with youthful vigor. They seemed to be as invested in pleasuring each other as they usually were in arguing with each other, which was a welcome sight to see. Despite the sexual incentives Shiro had behind disciplining them, he obviously wanted to see their relationship actually grow, too.

Their balls were smacking each other's faces as they humped into the mouth sucking them, with Lance's legs wrapping around Keith's neck to force him down more while Keith effectively fucked Lance's throat.

As the intensity of their mutual blowjobs increased, so did the intensity of Shiro's hand against his cock. Precum leaked from the swollen head as he gritted his teeth, chest heaving as he watched his two boys passionately bringing each other to completion.

Keith finished first, shoving his cock as deep down Lance's mouth as was possible, squishing his balls against his face as cum fired down his throat, and the sight of Lance's throat moving up and down was incredibly satisfying.

Next was Lance's orgasm, his moan vibrating as a muffled hum around Keith's dick as cum shot up into Keith's mouth. His entire lower half convulsed with each shot, legs tightening around Keith's head and forcing him to drink like his cock was a fountain.

Shiro couldn't help but jerk himself off even harder as he watched, completely entranced by the sight of the two competitors feeding each other their seed. Just watching their throats moving with such hunger and eagerness had him nearing his completion, and he immediately scooted to sit at the edge of the bed.

"Good boys. Now come, catch your reward."

They quickly finished licking each other off before obeying like trained animals, crawling on either side of Shiro's cock. Keith lead the attack by wrapping his mouth around one side, and Lance was quick to copy him until they were mouthing against his cock, as if hungry for more cum even after getting a mouthful of each other's.

Shiro's breaths mixed with his grunts as he pumped his cock faster and faster, eyes straining and going dark with lust as both boys moved to the end of his cock, mouths wide open with their tongues hanging out just beneath his tip.

Nowadays, he barely had to get off on his own anymore and was used to using Keith's body to orgasm, but the thought of having both of these boys drowning in his cum simultaneously made it easy for him to finish himself off as he roared in pleasure.

Searing hot ecstasy shot up his entire body with the suddenness and intensity of lightning, and his vision blurred with white as warm liquid erupted from his cock like a white volcano in what was easily one of the most intense orgasms he'd had, at least as of recently.

He could feel his core constantly tightening, pushing out more and more cum, spurred on by the sight of Lance and Keith fighting to catch his seed in their mouths. Then, once he finally thought he had reached the climax of his climax, Keith and Lance smashed their cum-filled mouths together like the kinky little sluts they were, and the sight of them sharing his load had Shiro shooting one or two more times just from how impossibly hot they looked.

Once the last of his climax drained through his body, he fell back onto the bed, eyes rolling up in pleasure as the two boys followed his cock to lick the head clean, kissing each other in the process.

"Such good boys..."

They both flopped down on either side of Shiro once they finished adequately cleaning him, and it was times like this that gave Shiro the most satisfaction over how well disciplined they were for him, even though this was Lance's first time joining them for sex.

"You did well for your punishment. Sleep now—and prove to me tomorrow that you can be good boys who learn."

Both boys practically purred as they curled into Shiro's sides and practically fell asleep on command. He could only smirk to himself in content.

Another lesson successfully carved into them.
