Pen at the ready, I watched as Kacchan pinned my boyfriend to the bed. We all knew that if Shouto really wanted to he would buck him off, sending him flying to the other end of the room without too much difficulty. However, this was meant to be a demonstration - a way to show just what Kacchan could do when Shouto couldn’t really fight back.
“You’re weak.” Kacchan spat. “Hurts me a little to know I could have made something as feeble as you.” Though the hatred in his words wasn’t surprising, the tone was definitely different, somewhat more familiar like the vitriol ran deeper than what Kacchan usually reserved for almost anyone that got in his way. Kacchan was playing a role and judging by the little bit of fear in Shouto’s eyes, he was playing it well.
'Subtlety = good. Don’t over exaggerate.' I wrote down, eyes flickering quickly between the notebook and the display on the bed. Kacchan had told me that he would pretty much ignore me as this scene was going down, if I wanted to learn I had to watch, listen and try not to get so turned on that I couldn’t take down anymore notes.
I folded my legs a little closer, leaning in as Kacchan slapped Shouto clean across the face, making the quieter of the two start growling and bucking against him.
“I don’t belong to you.” hissed Shouto. “You can’t fuck with me like you used to.”
Kacchan’s grin was sickening Whenever Kacchan got into one of his moods, there was still something playful about it - he would never really blow you to bits and just wanted to make sure he got a message across to anyone that tried to mess with him. This smile, though, there was something raw - hatred for the sake of hatred - domination simply because he could.
I tried not to notice as Shouto’s hips started moving as he shifted around on the bed.
“I can’t?” Kacchan said, before smacking Shouto again and pinning his cheek down to the bed. “Look at you, you can barely fight back. What am I paying all this money to send you to that school for?”
“You wanted me gone.” Shouto growled, I tried to quickly write down Kacchan’s words, knowing that he must have been that good of an actor to get even Shouto to play along like this. “You couldn’t stand the fucking sight of me anymore so you shipped me off and made me someone else’s problem.”
Kacchan kinda softened a little at that (er...softened as much as he could given the role he was playing) before easing up the pressure he’d put down on Shouto’s face.
“That’s a big fucking lie and you know it, son.” he purred, the dip in his voice causing Shouto to shiver. “The house is so lonely without your ass around here, part of me misses you.”
Shouto had to stifle a moan as Kacchan ground down on him, but he kept playing up the angle perfectly. “What part, old man?”
“I’m not sure, Shouto.” he whispered, smiling as his hand began to wiggle its way down to the waistband of his sweats. “Maybe seeing my cock down your throat will jog both our memories.”
There was still a bit of fear in Shouto’s eyes for the sake of the show they were putting on, but I could see the little flashes of excitement hidden behind the facade. He continued struggling as Kacchan worked his cock out of his pants and gave it a few slaps against Shouto’s face.
My own dick twitched but I tried to ignore it, scribbling down: ‘The power is in how you carry yourself, not always what you say.’
“Did you miss this, hm?” Kacchan all but purred, circling the tip around Shouto’s mouth. “Little fag like you would, obviously.” I tried not to wince at Kacchan’s choice of words, but judging by how Shouto didn’t freeze up, I relaxed myself and went back to taking notes.
‘Your boundaries aren’t their boundaries.’
Shouto’s lips were sealed tight and he kept turning his face away from Kacchan’s cock, much to his chagrin. It didn’t take long for Kacchan to get sick of it, shoving Shouto’s head backwards by the hair and wrenching his mouth open with his other hand.
“Don’t test me boy, I don’t want to have to singe this pretty face.”
I thought I heard a tiny moan come from Shouto, but it was stomped out as soon as Kacchan started fucking his face. I was doing my best to simply concentrate, watch as if I were just in class and I had a test coming up soon. It was a demonstration, not meant to arouse but to teach.
I wish someone had told my cock that, honestly.
“That’s it, you always open up so nicely for Daddy, don’t you? Even with all this struggling and shit you know you can’t hide from how much you want it.” he smirked, his rhythm in Shouto’s mouth already starting to move into the realm of punishing. He groaned with every push inwards, but he kept looking down at our Shouto, watching as his eyes started to slide closed and tiny tears began to erupt from the corners of his lids.
Still, despite the pitiful display underneath him, he showed no sign on stopping. I tried to hold my cock down a bit, think of something thoroughly un-sexy in order to just observe and listen, try to think about the show in front of me as though it was like a nature documentary. None of this was meant to be sexy, it was supposed to instruct. To be entirely sterile, analytical and -
“Such a good fucking boy for Daddy. Fuck, I missed this so much. Stop fucking crying.”
I noticed how I’d started to create an inkblot on the page with how long I was holding the pen there and quickly tried to recover from getting lost watching the two of them.
‘When you can be relentless, do.’ I wrote down, reading over my notes in an attempt to ignore the sights and sounds happening six feet away from me.
“I’ll give you something to cry about.” he hissed, stopping for a second so he could reposition himself and somehow shove in deeper. He pressed his hands against Shotuo’s throat, as if feeling his own cock move through the soft, trembling skin. “For all I know this is how you get top marks at that school of yours, you've been sucking off Aizawa under his desk after school so he’ll pass you?” Kacchan barked a laugh. “Little overachiever, bet you take him good.”
Shouto could barely struggle, could hardly come to his own defense as Kacchan berated him. Hell, it was definitely getting hard for him to breathe with Kacchan's cock down his throat, no doubt putting his weight on his chest to further trap and choke him.
Still, the act of the struggling, unwilling son was starting to fall away - and soon I saw as his arms went slack, body ceeding any type of control. Kacchan gave him a onceover, slowing down his movements as if to check if Shouto was okay.
He received a weak nod, permission to keep going and within seconds the show was back on. Kacchan was grinning as he fucked his mouth, one of his hands reaching backwards in between Shouto’s legs, wrenching tem apart before rubbing his hand in between them.
‘Keep them pliant by any means, so long as they’re okay with it.’ I scribbled, my dick continuing to harden as I watched Kacchan massage between Shouto’s legs.
Despite how stoic and willing he seemed from the waist up, there was no hiding how much Shouto loved Kacchan’s fingers or just - fingers in general. Hands were always his weakness, from casual grabs from behind to huge to the occasional smack of his ass, everything was enough to make him weak. Now that Kacchan was slowly working him over, no doubt making him soak through his boxers - he was moaning around his cock, unable to help himself.
“Little fag like you loves this, I knew it.” Kacchan hissed. “Even if you might spread your legs and open your mouth to some poor fucker at school, you always do it the best for your Daddy, don’t you?”
It happened quickly, but I watched as Kacchan’s hand ducked underneath Shouto’s boxers and judging by the way he keened, he must have done something very right.
The moans Shouto made around his dick were enough to send shock waves between the two of them. Kacchan kept teasing him underneath his boxers and I saw Shouto’s shaky hands start to dig themselves into the sheets. Even his muffled moans were gorgeous, his whole body moving as if it was trying to get more of Kacchan inside him, filling his mouth and his pussy until all he could remember was how good it felt to be underneath him like this.
After a few more minutes Kacchan pulled his fingers out, smearing the excess wetness on Shouto’s boxers as if he couldn’t even be bothered to put it on his sheets. “I think you’re ready now.” Kacchan pulled is cock out of his throat and moved towards the bottom of the bed. He allowed Shouto a minute to catch his breath, coughing and sputtering a bit before coming back to himself.
“Not so tough now, I knew it wouldn’t take much to get you where I wanted you to be.” Kacchan smirked. “Get out of those clothes.”
Shouto’s movements were slow as he took off his shirt, nipples almost boring a hole through it already. Kacchan’s eyes were hungry and I caught myself staring too. No matter how many times we’d both seen him naked, he was always gorgeous to us.
As he moved I caught a glint of the diamond in his ass - he’d worn his plug for this? My cock jumped and I tried to tell myself to just wait a minute until they were a little more preoccupied.
When his boxers were kicked onto the floor Kacchan put a hand against his shaky leg as if to steady him. “Time out for a second, are we still good?” he asked.
Shouto could only nod, relaxing back onto the pillows. “Yeah, we’re good.” he looked over to me and I quickly crossed my legs before I could properly fall under their gazes.
“I’m fine, you guys can keep going.” I said, knowing damn well how red my face was and how all the sweat was definitely making me look shiny despite the only light being the lamp from Kacchan’s desk.
If Kacchan noticed, he didn’t say a word, insteady roughly tugging Shouto down by his ankle and clamoring on top of him. Now that his attention was elsewhere, I tried my best to balance my notebook on my knees and write with one hand whilst touching myself with the other. Hopefully the shadows they cast would cover everything up.
I was trying my best to stifle my small, relieved moans when I finally looked back up. Kacchan was admiring Shouto’s pussy, much to the latter’s embarrassment.
“You’re still just as pink as ever.” Kacchan said and I watched as he stuck a couple fingers inside it. “Still just as tight too, nobody’s been fucking you at all?”
“That’s - ah, that’s not how that works, old m-” Shouto had to cover his mouth as if on instinct. This wasn’t one of our late night rendezvous in the dorms. We had the whole house to ourselves for the entire weekend but it was kinda cute watching him still be courteous despite his circumstances.
“Nuh uh.” Kacchan growled, slapping his hand away. “Wanna hear you, you never used to cover the noises you made even when everyone else was home, did you?”
I didn’t have time to pull my hand out of my pants before Kacchan glanced over at me. My belly turned to ice water and my hand froze in place. Still, the way he looked at me was no less hot. His eyes were filled with derision, austere and powerful, as if I should be lucky that I was the one making eye contact with him for this long.
After a beat he turned back, his fingers never leaving Shouto even after he’d been staring at me. Shouto was a mewling mess, pussy no doubt aching for the relief after having his body used like that. His legs shook with the force of it and despite Kacchan’s cock standing thick and heavy between his legs, he didn’t touch himself. Instead, he allowed his other hand to roam, teasing his nipples and smirking and Shouto got more and more desperate.
With bleary eyes and one hand I wrote down: ‘Drag it out if you can, make them want it more than you.’
“I know you want this cock, boy.” Kacchan growled after a few moments of torturing him. There was the wet sound of him pulling his fingers out before he moved closer in between Shouto’s legs, slapping his cock against his entrance.
“You’re perfect like this.” Kacchan groaned. “No matter how many times I do this to you, it never gets old.”
Shouto was a whimpering, moaning mess - with his hair splayed out and his chest heaving he looked like a painting. Sure, our Shouto could top and he was always just as gentle and refined and caring as he was when we all still had our clothes on. However, I think we were all in agreement he was at his prettiest just like this, control gone, sweet, soothing words all but fucked out of him and legs trembling, yet wide open.
With a sweaty, shaky hand I wrote ‘Compliment them, but don’t make it so obvious that you care.’
I kept stroking and watched as Kacchan slid inside, nearly doubling over as Shouto’s tight heat enveloped him. I could see that he was trying his best not to not break character, to keep up this little game as long as he could as he waited for Shouto to adjust.
“I was right.” he said, giving a few shallow, teasing thrusts inside. “Like a virgin, surprised those losers didn’t stretch you out yet.”
Before Shouto could give any smart remark Kacchan shoved in just a little more, letting the words die on his “son’s” lips.
They stayed like that for a while and so my stroking slowed just so Kacchan wouldn’t catch me getting off should he break his concentration. It wasn’t long before he started pushing inside, his rocking thrusts starting to quicken.
Shouto’s whines were garbled, buried in the back of his throat as though he didn’t want his ‘Dad’ to know he’d gotten the better of him. In true Kacchan fashion, he caught onto this quickly and soon Shouto had to grip onto his forearms, digging his nails in as though he would go flying off his dick at any minute.
“Yeah, I knew it. You’re a craven little fag for me.” Kacchan huffed. “Nobody at that school fills you up like your Daddy does, hm? You’ll always come crawling back for more once they’ve left you wanting?”
Shouto’s lack of an answer earned him another sharp slap and he whined out a ‘Yes, Daddy!’
I think me and Kacchan moaned in unison.
Kacchan kept fucking im wildly, growling how good he was in his ear and Shouto could only nod, the fight fucked out of him and his body pulling closer towards Kacchan as he was swkereed onto him over and over again.
“See what happens when you give in? How good it is when you just let Daddy do what’s good for you?” he smirked, slowing his thrusts so he could just grind up Shouto’s insides and watch as he wrapped his legs around him, trying to keep him from pulling out entirely.
Kacchan laughed. “Just face it, unless it’s me you’ll always feel empty. Nobody can fill you and keep you nice and pliant like your Daddy can.”
I could feel the sweat in my hand being joined by precum as Shouto gasped “N-nobody…”. Kacchan, obliging him, refused to pull out, instead snapping his hips forward just a few inches to keep himself buried deep inside our Shouto. He let his hands wander, toying with his clit and tugging at his nipples again.
They quieted down just for a moment before Kacchan pulled out. A pathetic little noise crawled up from the back of Shouto’s throat, but died once Kacchan piped up again.
“It’s not fair you had to wear that little plug of yours and your good-for-nothing brother is home for once.” Kacchan smirked before turning to me again, eyes nealy crimson against the lamplight. ”Get over here, Touya.”
It was as though my legs had been stuffed with cotton as I shakily got up from my spot on the floor and walked over. They were both staring at me expectantly, Kacchan’s eyes nearly mad as he watched me move closer.
Before I had even reached the bed he was yanking me towards him, pulling me so that his teeth were right up against the shell of my ear. “No fucking point in me showing you how to do this if you can’t to it in front of me.” he whispered.
“Yeah, you’re right.” I said, far too quiet to be confident, but I was trying my best.
“And you always were a fast learner, weren’t you Touya?” His voice was louder this time and I couldn’t tell whether or not he was talking to me or Shouto.
“Of course, Dad.”
Kacchan smirked and patted me on the back before moving away a little, “How do you think we should have him?” he asked.
My notes came back to me and I started to act, slowly pulling the plug out of him (the gasp he made was enough to get my cock to jump). I started moving up on the bed, pushing him away from the pillows so I could slither underneath him.
I could feel just how wet he was as my cock came to rest just by the crack of his ass. His body was trembling but his skin was prickling with warmth and anticipation. I looked up at Kacchan for approval only to find he was already positioning himself back at Shouto’s pussy.
“Good job, son.” he said and though the most I could do was spit on my hand and rub it on my dick nobody seemed to be complaining. After all, it seemed the Todorokis could take a hit.
Kacchan spread his legs a little more, allowing both of us better access. I silently regretted not positioning myself on top, wanting to see just how our Shouto would look once we were both inside him. However, something told me not to mourn it too much, I doubted this would be our last opportunity for this.
Despite the slightly awkward angle I managed to slide the head inside Shouto relatively easily. Judging by the look on Kacchan’s face, the moans above me and the clenching around me, his pussy was getting filled at the same time.
“You like having your big brother in your ass like that?” Kacchan groaned, stilling for a moment to let me sink the rest of the way inside. “I’m sure he missed you, didn’t he?”
I tried to come back to myself, speak whilst relishing in the feeling of Shouto’s ass clenching around me. The words came out slightly muttered, but I was close enough to Shouto’s ear where I’m sure he heard them perfectly.
“You’re so tight, little bro.” I whispered, my teeth grazing the crook of his neck. “Hope I’m the first one to use this hole, nice to think you waited just for me.”
“Only you, Touya. Fuck..” he groaned.
My sweet talking earned me a little clench as he moaned and pretty soon we were both thrusting inside him. I could only groan at how tight he was, driving up into this warmth as much as the angle would allow. Kacchan was no better, only slowing down his thrusts for my sake, but not letting up with just how hard they hit when he slammed home.
It was hard not to get lost in the feeling of our Shouto like this. His moans were nonstop and his whining and begging was like music. I couldn’t help but lose myself a little, only being able to muster that I loved my little brother and how cute he was and how much I missed him - how much I’d wanted him since I’d left.
Kacchan, keeping up his role as horny, yet aloof was doing his best despite how gorgeous Shouto probably looked beneath him. He egged me on a bit as well, probably wanting me to be a little rougher. Still, I liked the character I created and I wasn’t rough with my words so much just as my actions, a great example being how I jabbed against his prostate, muting his moans for just a second before he started pleading with me to do it again and again and again..
“Touya please, I need your cum. P-please, please…” I was shocked, not expecting him to want his big brother’s cum first and for a moment I felt a surge of pride in my chest. My baby brother wanted me, no need for me and who was I to deny him something so essential. I had to do my best to hold him to my body and keep him from arching away. I watched from over his shoulder as Kacchan’s hand moved to his chest again, trying to get him to clench up as much as he could so the both of us could cum.
I did the best I could and kept talking. I wasn’t gonna be as outright degrading as Kacchan. “Of all people you want your dad and your big brother to fill you up like this?” I smiled. “It’s so cute just how needy you can be, how you need a cock in both your holes just to help you sleep at night.” I smiled, kissing and nipping at his jugular. “I really should come home more often.”
In the midst of everything I could’ve sworn I saw Kacchan give me a proud smile before he went back to hammering the shit out of his ‘son’.
“Gonna breed you, Shouto.” Kacchan groaned. “Gonna fill up your pretty little cunt until it’s leaking out of you.”
Shouto’s whines and clenching only affirmed how much he wanted it. Reaching up I tugged some of his hair back before sinking my teeth into his neck - moaning as he fluttered around me.
“Both of you, want it - please - please…”
“Gonna give you what you want, baby bro.” I whispered. “You’ll never be empty again.”
Shouto’s nut hit like a gun going off. One second he was quiet and still and the next he was bursting spectacularly. I could feel the heat erupt against his skin, tiny bits of smoke that he tried hard not to have turned into any flames. His speech was scattered, switching between tines of curses and “DaddyTouyaDaddyTouyaDaddyTouya” until he’d babbled himself hoarse.
I slowed up just a little bit but Kacchan refused to hold back, slamming in just a few more times before all his buildup got the better of him and his final thrust was enough to nearly send Shouto off my dick and into the headboard.
The feeling of Kacchan leaking inside him brough another wave of greed clenched as he tried to milk him dry and I did my best to keep going, chasing the heat in my belly to its end as I whispered how lucky I was to have such a sweet little brother with such a nice ass.
Shouto was mewling and his chest was heaving by the time Kacchan pulled out and kissed him, whispering that he was going downstairs to grab some water before leaving the room. I’m not even sure if Shouto heard him.
“Hey, Shou. How are you? Are you okay?” I said, slowly pulling out of him and trying to ease him off me. “Can you breathe alright?”
“Mhm…” he whispered, winicing a bit as his sore ass connected with the sheets and he turned over on his side. I rubbed his arm a little, pressing soft kisses to his shoulder as his breathing started to even out. “You did really well.” he sighed out and upon further inspection I could see that his eyes were already closing. “Not that we expected any less of you.”
“So...you guys did plan out that last bit?” I said, crawling over his body and laying down besides him so that we were facing each other.
He smiled at me. “It was Katsuki’s idea, something about how you deserved a little bit of me as well.”
I couldn’t help but blush, the relative quiet of the moment broken as the door slammed open again and Kacchan all but chucked a bottle of water at my head.
“Good job, loser. Did you learn anything?”
I narrowly avoided being concussed and nodded a yes. “Figured as much, nerd like you can only get so far with notes. Sometimes you have to learn on the job.”
Always practical, our Kacchan.
Shouto rolled his eyes and sighed, muttering something about how Kacchan didn’t have an ounce of decorum in his body before receiving a kiss on the cheek from the blond in question. I handed Shouto the bottle of water and allowed him to get a few sips in before setting it on the nightstand.
He relaxed a little more into the sheets as Kacchan came up behind him, allowing him to slump against the warmth of his body. “How was that, Icy Hot?”
“Do we really need to do an exit poll after sex?”
“It's more for Deku over there than it is for me.”
Shouto rolled his eyes and chuckled. “You two were perfect. 10/10.”
I smiled and kissed him properly this time and turned his head so Kacchan could do the same before we both wrapped our arms around him, trapping him between us.
There’s always a moment after we both do this that he tenses, as if the sensation is completely foreign to him. Finally, his eyes closed and I felt his weight drop against us - safe and secure and tired.
I smiled a little to myself too, glad for the sweet silence in the room.
