It took every ounce of Katsuki’s willpower just to stay still. His body screamed at him to move, to touch, to make the most of his time, but he knew if he started, there was no way in hell that he’d be able to stop. He’d been there before, after all – gone for a leisurely touch and ended up caught alone in the bedroom with his pants down – literally. Shouto had not been happy with him, that day.

Izuku seemed to sense his pain, one hand sliding over his thigh lightly and making him squirm, the dick beneath him quickly getting harder as he moved.

“Trying to tempt me?” Izuku teased, nipping at his neck. “Hard to be patient, huh?”

“I’ve been patient,” Katsuki huffed. “For a year I’ve been patient.”

“You’ve been such a good boy,” Izuku agreed, wrapping his arms around Katsuki’s waist tightly. “I’m so proud of my Kacchan.”

“Ugh.”

He really should have known it was coming, when Izuku had insisted on pulling Katsuki into his lap. The nerd was always affectionate, sure, but there had been something so gleeful about him that day, and Katsuki had been surprisingly slow to catch on.

“We could sneak in a little fun before he gets home,” Izuku offered, hand sliding in between Katsuki’s clamped thighs. “You’re free now, after all.”

“Don’t be a jerk,” Katsuki huffed, tilting his head away from the kisses Izuku trailed down his neck. “You know he’ll be mad.”

“He doesn’t have to know.”

“He’ll know.”

“How can you be sure?”

“Are you testing me? Did he put you up to this?”

“Of course not!” Izuku pouted, and for a moment Katsuki felt a tiny bit bad. “Is it so wrong to want to play with my boyfriend?”

“Later,” Katsuki grumbled, twitching when a cold hand slid up his shirt. “When Shouto is home.”

“You’re such a good boy,” Izuku hummed into Katsuki’s neck. “He’dbe proud.”

“Shut up.”

“That’s not very nice.”

Katsuki snorted, but he tipped his head back to press their cheeks together lightly, affectionately.

“Shitty Hair was on me all day,” he grumbled. “Said I was acting weird and shit.”

“You probably were,” Izuku teased. “Did it feel good? Letting it all hang free?”

“I’m not dignifying that with an answer,” Katsuki grumbled, thighs tensing when Izuku’s hand pushed a little deeper between them. “Don’t be an asshole.”

“Asshole?” Izuku echoed, shifting his hips a little to press harder against Katsuki’s butt. “We can do that.”

“Needy fuck.”

“Says you,” Izuku snorted, giving Katsuki’s thigh a sharp tug and prying them apart. “Look at you.”

He cupped his hand around Katsuki’s dick, stroking the hard length, and Katsuki whined at the touch. As much as he hated to admit it, he’d gotten used to wearing the stupid cage Shouto liked to keep him in. Izuku’s touch felt so much more electric with it gone, he was so damn sensitive.

“Shouto’ll get mad,” Katsuki whined, tossing his head back onto Izuku’s shoulder pathetically. “I’ll be the one he gets mad at!”

“Hmmm, we wouldn’t want that, would we?”

He took his hand away as quickly as it came, and Katsuki wasn’t sure whether to breathe a sigh of relief or desperately beg for it back. Every piece of him screamed to grab the hand, to pull it back in, to finally let Izuku jerk him off – like Izuku wanted, like Katsuki deserved.

“I’ve been good?” Katsuki asked quietly.

“So good,” Izuku confirmed with a smile. “Can’t believe you lasted so long, Shouto was convinced you’d break and we’d get to punish you.”

“I can fuckin’ do anything.”

“You sure can. My good boy, I love it when you behave for me, it’s so sexy.”

“Shut up.”

“But it makes Little Kacchan so happy!”

He rubbed Katsuki’s cock again pointedly, and Katsuki groaned, bucking his hips up into the touch.

“I’m allowed to do whatever I want,” Izuku reminded him, grinning. “You’re the one who isn’t allowed to get off yet.”

“When did you turn into an asshole?”

“That’s not how a good boy talks to his boyfriend,” Izuku reminded him, squeezing lightly. “You get so grumpy when we let you out, don’t you? It’s a wonder that we still do it at all.”

“M’sorry,” Katsuki gasped, squeezing his eyes shut when Izuku stroked him slowly. “I’ll be good, I swear, I just-”

“I know,” Izuku chuckled. “I know you’ll be good, you’ll make me and Shou proud.”

“I just want to play with you,” Katsuki finished weakly. “Want to... Feel it.”

“You will,” Izuku assured him. “You’re gonna be a good boy for us, and we’re gonna treat you real nice in return, okay? You’re gonna feel so good.”

“Yeah,” Katsuki grunted. “Wish he’d hurry the fuck up and get home.”

“Maybe we should start getting you ready, so when he gets home we’ll be all ready to play.”

“Mmm?”

“Get you cleaned out for us?”

Katsuki’s cheeks flushed, and Izuku turned his head to catch a glimpse, raising an eyebrow at him with amusement clear in his eyes.

“You already did it?” Izuku asked knowingly.

“Yeah,” Katsuki grumbled, looking away quickly. “When I showered.”

“You’re so cute, all eager to play.”

“Thought he’d be home earlier,” Katsuki objected. “Asshole is just working late to make me wait.”

“Or he just got caught up with a villain. Or paperwork.”

“Yeah right.”

“So cynical. Well if you’re already clean, I guess we’d better get you stretched out nice and loose.”

“But-”

“But you’re not allowed to cum,” Izuku finished with a little smirk. “Sound like a challenge?”

Katsuki’s eyes narrowed, and Izuku grinned knowingly.

“Sounds like fun to me. I bet it’ll feel really good, too. I know it hasn’t been long since we fucked you, but it’s been a long time since you got to really enjoy it.”

“I always enjoy it,” Katsuki protested.

“I know, baby. I’m glad. But tonight is special.”

“Yeah,” Katsuki nodded faintly. “I’ll um, go get the lube?”

Izuku picked it up from the end table, and Katsuki barely managed to resist rolling his eyes.

“I’m prepared,” Izuku chuckled. “Turn around for me, straddle my lap.”

Katsuki didn’t bother to argue, obeying without question, and Izuku watched as the muscular thighs spread for him so easily, a little bulge showing off just how eager Katsuki was to get started. He held onto Izuku’s shoulders for balance, keeping himself from sliding backwards off Izuku’s lap, but he lifted up a little when Izuku reached for his sweatpants. The soft material slid off easily, even with their awkward positioning, and with some shimmies, some tugs, and a bit of contortion work for good measure, Izuku threw them away over the back of the couch – they wouldn’t be needed again any time soon.

“You look so good,” Izuku praised, wrapping a hand around Katsuki’s dick and making him hiss. “It must be so sensitive, huh? Little Kacchan isn’t used to being touched so closely.”

“Fuck,” Katsuki moaned, arching his back to push his hips forward, searching for friction in Izuku’s fist. “Fuck.”

“This is why we have to keep him protected,” Izuku smiled, letting go and watching Katsuki whine desperately in response. “Can’t have you going around all needy like this every day, right? What if a villain touched you? As sensitive as you are, you’d probably let them fuck you.”

“Never,” Katsuki complained, dropping his head to Izuku’s shoulder. “No villains, fuck that. Just... Just you. And Shouto. No one else.”

“That’s what I like to hear.”

Izuku lubed up his first two fingers, threading his arm between Katsuki’s thighs and slipping them into his hole. Katsuki clenched around him, biting back a moan, and Izuku smiled down at him. With his forehead on Izuku’s shoulder, Katsuki’s neck was so perfectly exposed, just begging for Izuku to cover him in bites and bruises. He caved to the urge just a little, turning his head to trail little nips down the smooth expanse of skin, but when Katsuki whimpered in response he couldn’t help but bite down a little harder.

“So good for me,” he praised, whispering into the red marks that bloomed on pale skin. “I love you, Kacchan. So amazing. Such a good boy.”

“Fuck me.”

“Patience, my love,” Izuku grinned. “Shouto will be home soon, then we’ll fuck you up properly.”

“Fingers.”

“Yeah, I can get you nice and stretched. You’ve gotta keep yourself under control, though. Don’t go finishing before us, you hear me?”

“I won’t, just... Fuck.”

Izuku’s fingers curling shut him up in a hurry, and soon his hand was finally moving, fingers sliding in and out, curling and spreading, making Katsuki’s breath catch at every little touch. His chest heaved with the effort it took to keep getting oxygen in his lungs, and Izuku bit down on his neck again, sucking gently to leave pretty mottled bruises.

“Fuck,” Katsuki hissed, his dick throbbing so hard he thought it might burst before Shouto got there. “Feels so good.”

“Yeah?” Izuku smiled, pulling back a little to get a good look at Katsuki’s twisted expression. “I’m glad. You wanna cum?”

“Of course I do,” he huffed. “But I can’t.”

“That’s my good boy. Even when your little hole is getting fucked, you still give the right answers.”

The front door opening made Katsuki moan louder than he thought he ever had. It was finally over, he could finally get fucked for real, feel warm hands wrapped around his dick and the sweet release of cumming all over their extra-large bed.

“You couldn’t even wait for me?” Shouto asked with a smirk, setting his bag down in the doorway.

“Sorry,” Izuku chuckled, raising his pace a little even so. “Kacchan said we should wait, but I just couldn’t resist his cute little squirms.”

“I understand, he’s hard to resist,” Shouto assured him, amused. “Kiss?”

He leaned over, and Izuku tilted his head to meet him, sharing a sweet little welcome home kiss while Katsuki continued to gasp and whine in his lap. He turned his head quickly when they finished, pouting, and Shouto chuckled as he pressed a matching kiss to Katsuki’s lips.

“Love you too,” he teased, when Katsuki pulled away to gasp at a particularly hard thrust. “You’re behaving for Izuku, huh? Seems like keeping you locked away has done it’s job, you’re so nice and pliant for us.”

Katsuki whined, ducking his head to Izuku’s shoulder again, and Izuku couldn’t help but be surprised that he wasn’t hit with cum in the process. Katsuki was such a sucker for compliments and praise, it was a wonder that he was still holding on.

“You’re so cute when you’re embarrassed,” Izuku grinned. “Shall we move to the bedroom now that everyone is home?”

“I might have a snack first,” Shouto mused. “Been a long day.”

Katsuki glared at him silently, and Shouto cracked a smile, reaching out to ruffle his hair fondly.

“What, you can’t wait five minutes?” he teased. “You desperately want to be my cock warmer while I eat a sandwich or something?”

Katsuki’s scowl deepened, and Shouto’s smile stretched wider in response.

“You’d like that, wouldn’t you?” he smirked.

“Maybe Kacchan should have a snack too,” Izuku suggested, smiling wryly.

“You think so?” Shouto asked, catching on quickly. “Has he behaved himself enough for a treat, you think?”

“Oh yeah, he’s been very good today. Have a seat, babe. I’ll go make you a sandwich while you take care of Kacchan.”

Izuku finally slid his fingers out of Katsuki, reaching for a tissue to wipe them off, and Katsuki pouted a little in response. He slid off all the same, letting Izuku get up with a last quick kiss on his cheek. Shouto took his place, getting comfortable on the cushions, pointing at the floor without saying a word. Katsuki carefully dropped to his knees, swallowing hard, and watched as Shouto unzipped his fly at an agonisingly slow pace. The wooden floor was hard beneath him, he had no doubt that his knees would be aching soon, but when Shouto shoved his jeans down to his ankles, he suddenly didn’t even care.

“Open,” Shouto instructed.

Katsuki’s jaw dropped before he even had time to process the command, and Shouto’s smirk stretched a little wider.

“Come on, then,” he said quietly, his voice going straight to Katsuki’s dick. “You can touch.”

He spread his legs a little wider, and Katsuki shuffled forward, slotting himself between them neatly. He licked his lips, and Shouto reached for him, running his fingers through Katsuki’s hair and making him shiver. Shouto’s dick was already hard with the anticipation, and Katsuki couldn’t help but enjoy the sight – it was good to know his boyfriend was affected just as much as he was.

“Don’t go too quick, I wanna watch,” Izuku called from the kitchen. “Kacchan always looks so sexy when he’s sucking you off.”

“Shut up,” Katsuki grumbled. “Starting without you.”

“Okay! Just don’t finish without me!”

Katsuki leaned in, wrapping his lips around the tip of Shouto’s cock, and Shouto bit down on his lower lip the moment he touched. For all his talk, he was still so affected by his boyfriends touching him, every single damn time. To Katsuki, it only made it even more exciting to watch him come undone, to see that usually impassive expression contort with gasps and moans. He was pretty sure most of his friends wouldn’t believe it if someone told them he liked giving blowjobs, or that he preferred being the one getting fucked, but hell, Katsuki was man enough to admit that he was one hundred percent a bottom. And with Shouto preferring to be the one on top, it worked out pretty nicely.

Well, other than Deku who could never make up his damn mind, but he supposed that fitted in pretty well too.

“Here babe,” Izuku grinned, joining Shouto on the couch and handing him a plate. “Relax, fill your tummy, and let Kacchan fill his!”

Katsuki levelled him with a stern glare, though he was sure the effect was pretty well diminished by the dick in his mouth.

“You wanna suck me after?” Izuku requested, eyes shining. “It always feels so good when it’s Kacchan.”

Katsuki just shrugged, turning his attention back to Shouto. Izuku knew him well enough to realise anything other than a “no” was a “yes”. But in the meantime, those bright green eyes lasered in on Katsuki’s every move, watching as he slowly leaned in closer, bringing his lips down Shouto’s shaft, feeling the hot, thick cock sliding slowly into his mouth. He paused for a moment when it reached his throat, and Shouto looked down at him pointedly, chewing on a bite of sandwich like it was all no big deal.

“Keep going,” Izuku encouraged him, leaning over to nudge him forward gently. “Get nice and full, Kacchan.”

Katsuki’s stomach swirled, but he obeyed all the same, taking a deep breath through his nose and pushing himself in closer. His nose touched red-and-white pubes, and he swallowed hard, feeling Shouto throb in his throat.

“You look so good,” Izuku praised. “So sexy.”

Katsuki tried his best not to react to the words, but he felt his dick swelling between his knees. Stupid Deku and his stupid praise always got to him in a way he didn’t expect.

He pulled back slowly, swiping his tongue back and forth wherever possible, and after a minute he began to move a little faster. As he began to bob in and out, Shouto’s chewing began to stutter, no longer the nonchalant snacking he’d started out with. A small part of Katsuki felt a little guilty – Shouto was usually starving by the time he got home, he probably needed the food – but most of him just wanted to smirk, wanted to taunt him about how affected he was by a little blowjob.

He moved a little quicker again, setting a steady pace, and Shouto moaned between bites, pausing to put a hand over his mouth to hide his blush. That was another thing Katsuki loved about making him come undone, it was one of the rare times that Shouto’s face betrayed him, flushing with colour in a weird bout of embarrassment that Katsuki would never understand.

“Good,” he choked out, when Katsuki’s eyes darted up to see it. “Keep going like that.”

Katsuki tried his best to move quicker again in response, and before Shouto could even find his voice again, Katsuki’s mouth was filling with hot, salty cum. He felt it spurt out over his tongue first, quickly moving in close to let it go straight down his throat instead, and Shouto’s fingers curled around his face, as if he might try to tear the colour out of his cheeks manually.

Katsuki waited for it to stop before he slowly slid his way off, letting Shouto’s dick fall limp between his thighs, and he looked up at Shouto expectantly.

“Good job,” he said awkwardly, breathless. “Thank you, Katsuki.”

Katsuki huffed quietly, a little amused by the awkwardness – because really, they’d been together for years, and he still got all awkward after a blow?

“My turn?” Izuku asked, eyes shining. “Kacchan is gonna be so nice and full.”

“In both ends,” Shouto confirmed, his composure quickly returning as he began to come down from the orgasm high. “Gonna fill you right up.”

Katsuki nodded faintly, a little dazed by the thought – something about their dirty talk really got to him, no matter how often they did it. He supposed he shouldn’t really make fun of Shouto for still being affected by things when he was exactly the same way, but they didn’t need to know that.

“Are your knees okay?” Izuku asked, ever the fusser. “Here, take a cushion.”

He didn’t bother to wait for a response, already taking one of the decorative couch cushions Katsuki had picked out when they moved in and shoving it at him. He took the briefest of moments to consider arguing, but decided it would be quicker to just comply, slotting it under his knees and reaching for Izuku’s fly.

As soon as Katsuki got his lips around the tip, Izuku bucked his hips up, thrusting himself into Katsuki’s mouth. It took everything in his power for Katsuki to not gag, but he swallowed valiantly, refusing to let Izuku have the satisfaction.

“Such a good boy,” Izuku grinned, tangling his fingers in blond spikes and pulling him close. “Feel so good on my dick.”

Katsuki’s eyebrows knitted together, but before he could begin to think of protesting, Izuku was pulling his hair, dragging him in and out at a steady pace. Katsuki glared at him for it, but Izuku seemed unswayed, his eyes glazing over when Katsuki swallowed around him.

“That’s what I like to see,” Shouto hummed, leaning against Izuku’s shoulder to watch. “I like it when you’re rough with him, it’s sexy.”

He took another bite of his sandwich, and Katsuki resisted the urge to reach out and pinch him for the words – that would not have ended well, no matter how satisfying it would be in the moment.

“I wanna fuck him first,” Shouto murmured through his mouthful, dragging Katsuki’s eyes back to him immediately. “You’re too gentle with him.”

“Oh?” Izuku grinned, turning his gaze down to Katsuki’s stretched lips and watery eyes as Izuku continued to fuck his mouth. “Am I being too gentle, Kacchan? Can’t have that, can we.”

Katsuki did his best to glare, but from the lack of response he suspected he’d failed.

“Gonna make him cum for us,” Shouto continued, contorting himself a little to kiss Izuku’s neck. “Then you can fuck him in your sweet, caring way, while he’s all overstimulated and cute.”

“That does sound good,” Izuku agreed, not missing the way Katsuki shifted his thighs a little as his cock throbbed. “I’m getting close, you want me to get you ready to fuck him?”

“I’m good,” Shouto assured him, setting aside his empty plate. “Thanks for the food, it was delicious.”

“You’re welcome!”

He picked up the lube Izuku had been using what felt like hours ago, and Katsuki’s eyes locked on his hand as he began to stroke himself, quickly getting himself back up. Shouto had always had a near-insatiable appetite in the bedroom, was always ready to go again in five minutes while Izuku and Katsuki were exhausted, but honestly Katsuki kinda loved it – not that he’d ever admit to that.

Izuku yanked Katsuki in close, quickly distracting him from the show when a burst of fluid hit the back of his throat. He didn’t have time to gag, forced to swallow it before the next shot came close behind, and slowly the fluid began to taper off, Katsuki’s raw throat finally getting a break.

“Good boy,” Izuku praised, making Katsuki squirm even as he sat back and rubbed his tired jaw. “I can always count on my Kacchan to be a good little fuck toy for me!”

Katsuki moaned, quickly slamming his mouth closed to stop it, but his boyfriends were already smirking at him, enjoying the heat that was quickly rushing to his face.

“C’mere baby,” Izuku instructed, gesturing with his hands. “Gimme a hug.”

Katsuki grumbled a bit just for show, but he rose carefully to his feet, ignoring the dull ache in his knees as he slid in between them on the couch. Izuku wrapped him up in a hug, sprawling him across the cushions, and all he could do was lie awkwardly in the grip, letting Izuku nuzzle his face and hair fondly.

A warm hand touched his bare skin, and then Shouto was thrusting inside of him with no warning, finally filling the space Izuku’s hand had left behind. It felt like he’d been empty for years, just waiting for something to finally fill him up again, and Shouto did it so perfectly. Long and thick, stretching him just a little bit wider to make space, brushing against every single nerve and best of all, hitting his prostate every time he passed it, sending jolts of an almost painful pleasure through his body. It felt like that one spot sent every part of his body into overdrive – his back arching, his mouth falling open on a gasp, his legs tensing around Shouto’s hips. The only thing that stopped him from moving – whether to chase it or to run away he wasn’t sure – was the grip Izuku had around him. With the way Izuku held him, arms looped beneath his, and the way he pulled Katsuki into him just slightly, ruining his weight balance, Katsuki was stuck. He didn’t have enough room or control to adjust his position, he just had to lie there, while Shouto and Izuku held him where they deemed fit.

Why was it so damn hot?

“Feel good, Kacchan?” Izuku prompted, seeing his realisation hit him. “Isn’t it so nice of Shouto to fuck you so nicely? On such a special day?”

“Ffff... Yeah.”

“That didn’t seem very enthusiastic, Kacchan.”

“Fuck,” Katsuki hissed, when Shouto thrust into him a little rougher. “Yes. Fucking- Feels good.”

“Don’t you think you should say something to him? For letting you play today?”

“Ffffff- Thank you. Fucking- Thank you, Shouto. Sir. Ah!”

“There’s our good boy!” Izuku grinned, kissing his cheek. “I like it when you’re polite for us.”

“Fuck.”

“I think you like it too,” Izuku laughed. “I bet Shouto will let you cum, if you ask very nicely.”

“Ugh.”

“No swearing, that’s not very nice.”

“Ugh! I want- I need- Sh-Shouto, p-please. Please, I need- Can I-”

Katsuki hated himself for the whiny half sentences falling from his lips, but he just couldn’t seem to keep a thought in his head for half a second – every time Shouto pounded into him again, he just forgot how to speak entirely.

“You want to cum?” Shouto prompted, his voice a little breathier than usual.

“Please.”

“You can cum,” Shouto agreed. “Since you’ve behaved yourself so well.”

Katsuki moaned, long and loud, and before he even knew it was happening, his cum was staining the couch. Izuku grinned when he saw it, when he felt the sticky mess pooling against his leg on the couch cushions, but still Shouto didn’t slow his pace.

“He’s gonna fill you up so good,” Izuku whispered, lips right beside Katsuki’s ear. “You’re gonna be so full of our cum.”

A whimper came out of Katsuki, unable to manage anything more significant, and as Izuku stroked his hair and cooed praise in his ear, Shouto finally came. He buried himself deep in Katsuki’s ass, hands curled tight around Katsuki’s hipbones. Katsuki felt a faint ache beneath them, a familiar feeling of Shouto’s quirk acting up, his handprints marking themselves on pale skin in a way that would take a few days to fade – Katsuki knew from experience.

“You want a turn?” Shouto asked breathlessly, eyes darting up to meet Izuku’s. “He feels so good when he’s already finished.”

“Absolutely,” Izuku agreed eagerly. “But you might need to help him out.”

“I can do that,” Shouto assured them, levering himself up and pulling out, making Katsuki whine again. “Look at you, you love this.”

Katsuki didn’t bother to object, letting Shouto wrap strong arms around his thighs and haul him up off the couch. He leaned in for balance, resting his head on Shouto’s shoulder, and Izuku reached up. He made little grabby hands until Shouto moved closer, letting him pet Katsuki’s hair fondly, and they both smiled when Katsuki hummed contentedly.

“Sit,” Shouto instructed, and Katsuki looked back curiously – when had Izuku moved? “You, Katsuki.”

Katsuki blinked a few times, prying his head up off Shouto’s shoulder, and he finally caught on when he saw Izuku sitting in wait.

“Oh,” he said softly. “Okay.”

Izuku spread his legs a little, and Shouto set Katsuki down on top of them, getting him lined up carefully. Katsuki lowered himself onto Izuku’s dick, biting down on his lip to keep from making a sound, and Izuku’s hands went immediately to his waist, right above Shouto’s marks.

He braced himself on Izuku’s thighs, leaning forward to rise up a little, but then Shouto’s hands were on his thighs again, lifting him higher, his hands torn away to leave him helpless in Shouto’s arms. Then, without a word of warning, he let go.

Izuku guided him down on the right angle, but gravity pulled him in fast, and he almost yelped when he felt Izuku fill him back up so quickly. Before he could even process what was happening, Shouto was picking him up again, and Katsuki quickly resigned himself to his fate – he no longer had enough strength to do anything himself, he just had to rely on his boyfriends to take care of it, to take care of him.

Being so helpless should have felt scary, but Katsuki had been with them far too long for that. Despite his usual anxious tendencies, his brain was full of a pleasant fog, addled by the post-orgasm bliss that he sometimes wished would just last forever.

“You look so pretty like this,” Shouto told him, shifting one hand to stroke his hair awkwardly – Shouto had never been great at the whole praise and affection thing. “Feel so good for us.”

With a few more helpless strokes, Katsuki felt Izuku tense up beneath him, and soon another burst of warmth was filling him up – lighter this time, compared to the blowjob, but that was pretty typical of Izuku’s second-time orgasms.

Part of Katsuki hated that he knew that.

Izuku pulled him back down, leaving him full of cum and dick alike, a mix of both his boyfriends being shoved deeper inside of him by the softening cock that didn’t seem to be going away in a hurry.

“So perfect,” Shouto praised, leaning in to kiss Izuku over Katsuki’s shoulder. “Both of you.”

Katsuki tilted his head back to get a glimpse, watching his boyfriends make out over top of him, but he couldn’t even be mad about it with how hot it was to watch. Shouto seemed to feel the gaze on him, his eyes cracking open to look, and Katsuki could feel the teasing in his gaze, could practically hear him ask what, you feel left out or something?

“Kacchan’s turn,” Izuku whispered knowingly, a fond smile playing at his lips. “Since he’s been so good for us today.”

“Yeah,” Shouto agreed, making Katsuki’s heart flutter. “You can have a kiss too.”

His warm lips claimed Katsuki’s immediately, and Katsuki melted into his touch, eyelids quickly fluttering closed as he savoured the touch.

All too soon it was over, and he was whining pathetically, listening to them chuckle at him as Shouto reached for his bag.

“I brought you a little present,” Shouto explained, pulling out a cardboard box. “Since today is a special day, and all.”

Katsuki watched as he pulled a shiny new cock cage from the box, all sleek black and sexy, and Katsuki couldn’t help but think that he’d do just about anything for the smile that was on Shouto’s face as he held it up.

He reached his hands out, shaking his head when Shouto started to offer him the cage, and with a knowing little chuckle, he leaned in to give Katsuki another kiss instead.

“Can I have another shower first?” he asked quietly, looking down at the sticky mess coating his crotch and thighs.

Izuku laughed brightly, and Shouto’s smile stretched even wider as he nodded.

“Why don’t we all have a bath together?” he suggested, watching Katsuki’s eyes widen – it was never Shouto who suggested the bath, was always Izuku and Katsuki on their cold, sappy days. “A nice bath, a hot dinner, a good sleep, and in the morning we’ll put you away before you go to work, to keep you safe and protected for us.”

Katsuki nodded faintly, a little concerned it might be a test of some sort, though Shouto looked completely innocent about the words. No gotcha came, though, just a matching little nod from Shouto, and Izuku gently helped Katsuki up off his cock.

“I wonder how long it’ll be this time,” Izuku mused, more to himself than the others.

“Maybe we can do it again soon,” Shouto hummed. “If Katsuki keeps being such a good boy.”

Izuku’s face lit up at the words, and Katsuki clapped a hand over his own mouth, attempting to stifle the loud moan that came out of him without his permission. Shouto just smirked at him knowingly, and Katsuki knew the way his tired dick twitched had not gone unnoticed. He couldn’t even find it in himself to be upset about it, though – Shouto never used those words, and fuck, he kind of loved it.

“Think you can do that for us?” Shouto teased, making the most of his height by kissing Katsuki’s fluffy hair. “Keep being good?”

“Yeah,” Katsuki nodded, swallowing hard. “I can.”

“There’s our good boy.”
