Work Text:
Izuku had discovered something unexpected.
It wasn't through an intentional breech of Katsuki's privacy. It was entirely coincidental.
He had arrived at his boyfriend's dorm room to spend time with him. It was Izuku's turn to pick a movie and he and Katsuki had already given each other their passwords, and blanket permisson to enter each other's rooms.
When he arrived, he received another text from Katsuki, telling him that Kirishima had some emergency that he needed Katsuki's help with.
Katsuki told Izuku to wait in his room until he came back, so Izuku did. He was ready to open the blonde's laptop to find a movie as planned, expecting to see Katsuki's streaming services folder, however, he opened the laptop to something else entirely.
There was a muscular man gagged and tied to a chair. Another man held a vibrator to his cock, which was stuck in a cock ring, as he squirmed. As he seemed close to orgasm, the other man tore the vibrator away, and the bound man looked wrecked, letting out desperate whines.
Izuku gasped. 'This is umm... wow.' He thought to himself, feeling his cock twitch.
'Does Kacchan want this with me? I usually bottom, does Kacchan see me like this? Does he want to tie me up like this?' Izuku wondered, rubbing his thighs together.
The bound man clicked his fingers once and the other man quickly removed the gag.
'Yes? What do you need? What's your color?'
'I'm green. I'm green, but Sir the vibe it's too much! Ah I can't take it anymore! I need you! You! Please Sir!'
The other withdrew the vibrator. 'You need me? What do you need from me? Hmm? '
'Please fuck me!' The sub begged.
'One more edge. One more, and then I will fuck you. You're green, so stop begging.'
The sub whined desperately. 'Sir please fuck me now!'
The dom slapped the sub across the face.
'Did you not hear me when I told you to stop begging bitch? I'll keep the gag off so you can safe word, but now i'm going to edge you three times, and you're going to beg me to cum like the slut you are, but I won't let you.'
Katsuki entered his room and Izuku slammed the laptop shut, throwing it across the matress startled. They stared at each other, wide eyed and red faced when Katsuki's eyes flooded with betrayal, and an angered expression appeared on his flushed face.
"Y-You saw!?" Katsuki rasped.
"W-Well I- Kacchan I promise I didn't mean to snoop! I had just wanted to find a movie for us and... uhh..." Izuku trailed off, because he noticed Katsuki's expression shifted from rage into embarassment.
"Kacchan! I uh- I don't know what you are thinking, but you have nothing to be ashamed of or anything! I actually thought it was hot too!"
Katsuki moved to sit beside Izuku on his bed and grabbed one of Izuku's hands, his other gripping his own chest. He looked down into Izuku's eyes. Down because Katsuki had grown quite a bit taller than his boyfriend, a fact he never let Izuku forget. His hand entertwined with Izuku's so perfectly. "You did?" He asked skeptically.
Izuku looked away and merely spread his legs a bit in response, revealing the issue that had arisen in his shorts.
"Oh." Katsuki said pointedly.
Izuku simply nodded with his face flushed.
"Is it something you wanted to try with me?" Izuku questioned.
Katsukis's face went crimson. "Which part?"
"I mean like, umm, did you wanna tie me up like that and uh, umm, edge me?"
Katsuki's face immediately paled and his expression became strained. "Fuck no! That's not what I- shit! Just no no no! Dammit!" Katsuki pulled at his own hair in aggravation.
Izuku withdrew his hand from his boyfriend's. "Ah. Okay, I understand so you don't have to keep saying it. Y-you don't want that with me, that's fine. You just like the porn or maybe i'm not the person who you wan- "
"You- Shit! Fuck! No you're misunderstanding!" Katsuki looked at Izuku's dejected face and yelled in panic.
"AGGH! FINE GODDAMIT DEKU!" Katsuki yanked the laptop open and shoved it unceremoniously into Izuku's lap. "Just watch it until you get it nerd!"
Izuku yelped as the porno continued, this time with his boyfriend watching him watch it. He gulped as he turned his attention to the screen, fully focusing.
He noticed details he hadn't before, like how the one who was tied to the chair was blonde, and Izuku himself had a build more similar to that of the green eyed dom, than the bound man.
'God you're such a slut for it. Are you that desperate?' The dom teased.
The sub whimpered, thighs trembling having been edged again. The dom gripped blonde hair tightly.
'Answer me, or are you that much of dumb bitch that you-' The sub cuts the dom off.
'I am!' He cried fat tears rolling down his face 'I am a desperate slut for it! I need it! I need you please Master, fuck me fuck me fuck meee!' The sub begged and groaned.
''Look at you begging like a whore. God you're such a slut, but you are my slut'.The dom reached back and took a butt plug out of his own ass before lowering himself down on the subs dick, the sub who cried and whined and-
'Oh.' Izuku thought. 'Kacchan wants to submit to me.' And wasn't that a thought. The thought of Katsuki, bound to a chair, crying and begging for Izuku to 'please fuck him'...
He closed the laptop, and Katsuki turned away from him looking ready flee from his own room.
Izuku reached for his boyfriend's shoulder. "Kaccha-"
"Don't! Dont pity me or try to comfort me, just go!" Katsuki yelled.
Izuku leaned forward and hugged Katsuki's back. "I liked it Kacchan."
Katsuki whipped his head round and stared at Izuku. When he found pink cheeks, hazy eyes and a persistent erection similar to his own, he turned back to face Izuku fully and gave him a look.
"You ain't lying to me Deku? You mean it?" He asked low and husky.
Izuku's ears went red as he nodded. "I mean obviously we need to talk about it firs-" He was interupted as Katsuki dragged Izuku into his lap and kissed him up into his mouth intensly.
Over and over, all open mouthed with tonue and teeth, it was raw, and hot, and passionate, and then Katsuki pulled Izuku closer and grinded their cocks together. Izuku wrapped his arms around his boyfriend's shoulders, to which Katsuki gripped his hands around Izuku's waist, for extra leverage in his upward guided thrusts.
Izuku drew back. "We need to talk about thi- Mmh!"
Katsuki growled and gave Deku a nip on his neck before grinding again and again. "Dekuuu." He moaned and he dropped his head into Izukus shoulder and clenched his teeth into Izuku's shirt to silence himself.
Izuku was conflicted, knowing this conversation had to happen, but, the thought of Katsuki in that position begging for him, and now when they were both raring to go he just... He's only human.
"If we're going to do something like this right now, no penetrating. I don't want to go too far without a proper discussion. And don't forget i'm not experienced in this at all, i'm just going to go with things I have seen in porn and make educated guesses. And you have to tell me if you genuinely want to stop anything! If I do anything you don't like at all. Promise?"
Katsuki dropped Izuku's shirt collar from his mouth. "Yeah, fuck yes Deku. I will to all of that stuff and you too. I promise i'll talk to you if need to so..." Katsuki grinded up.
Izuku grinded down. "So Kacchan wants me to tie him up? Take control and edge him till he's desperate? Needy for his cock to be buried in me?"
"Nnghh fuuuck fuck Deku!" Katsuki whined and grinded up harder and faster, humping desperately, their hips creating the most delicious friction. He pulled his own shirt clenched between his teeth in a meager attempt to keep quiet as his fantasy came to life. He drooled and moaned into the shirt.
"Yes Kacchan. Making me feel so good. Good. Ahh! Kacchan you're so good!" Izuku gripped Katsuki's back hard, surely leaving marks even through his tank top and Katsuki whimpered.
"You liked that." Izuku smiled. "Was it because I called you good? You like it when I call you good Kacchan?"
Katsuki nodded rapidly. "You're so good, you're amazing, Kacchan's the best! Good-nngh... Good boy!"
Katsuki groaned and stilled, leaving Izuku fully in control of the pace.
"What's wrong Kacchan?" Izuku bounced, almost as though he was riding his boyfriend. "You were doing so good, this is what you wanted right? Me in control. If that's right, then c'mon keep grinding up into me like before. Kacchan don't you want to make is feel good? Don't you wanna be good?"
"I..." Katsuki started in a shaky voice, muffled by the shirt, and Izuku stopped grinding, thinking maybe this was too far.
Katsuki shuddered from the sudden difference in stimulation, and leaned back, letting the shirt go and gripping his own thighs. "I wanna..." He panted and squeezed his eyes shut in concentration.
"If you're gonna call me good I wanna earn it first. I really like it but... But I also want you too..." Katsuki glanced at the laptop and then back at Izuku with watery eyes filled with shame.
Izuku thought hard for a second when he rembered the language used in the video.
"You want me to be mean to you Kacchan?" Izuku asked softly.
Katsuki turned his head away and gave a short and curt nod.
"I could but is that a good idea? For us I mean? I feel like this could be reverse progress for certain issues."
"No, it's nothin like that I just. I- Shit! When I fantasize about this shit, I like it when you're callin me names and stuff... I know that it's weird cause I bullied you, but I promise it ain't like atonement or anything it's just hot. I can't explain it but, I know I fuckin' really like it.
"Okay Kacchan, I just wanted to make sure. As long as you definitley want it because it makes you feel good?"
Katsuki nodded.
Izuku tilted his head. "Is that how we ask for things Kacchan?"
Katsuki looked confused.
Izuku smirked, then licked his lips. "If you want me to degrade you then you have to ask nicely, and tell me what you want. If you want me to degrade you, then you have to beg me for it."
Katsuki's face went red in splotches and he let out a desperate noise."Deku, that's so..."
Izuku's eyes darkened. "Humiliating?" He smiled. "That's what you wanted though baby. You can do it Kachan, be a good boy and beg. Ask nicely."
Katsuki trembled and shook his head embarrased, but he continued his own grinding against Izuku.
Izuku tutted. He moved all the way to the other side of the bed far enough to stop them from touching entirely. "Kacchan can't touch until he properly begs for what he wants."
"Huh?" Katsuki said confused.
Izuku used one hand to slowly drag his own shirt up, and tweak at his nipple. The other, he trailed down over his clothed aching cock, and he stroked himself through his shorts.
"Ahh Ngh! If you won't beg for what you want Kacchan, then yo-Hmh! You can't touch me, or yourself. And I'll finish myself off and leave you like this." He pointed at Katsuki's trapped throbbing dick with his foot.
Katsuki looked hurt, and frustrated and wonderfully desperate. He said nothing. Izuku persisted. He slowly dragged his shorts off and pulled his boxers down, hissing as his cock bobbed. He rubbed up and down his dick faster and harder. He smeared pre around his cock slowly, as he caressed his bare foot along Katsuki's calf through his sweatpants, who shivered but stayed silent.
"Ah! Oh! Mmh! Yeees!" Izuku moaned as he held eye contact. He slid his foot up more and more, until his leg was fully stretched, making his thick muscular leg tense, which he knew Katsuki liked. His foot gently grazed along Katuki's upper thigh. He bit his bottom lip.
"...se." Katsuki whispered.
Izuku smiled "Hmm? What was that Kacchan?"
Katsuki shifted to hump the bed hoping to soothe his aching cock
He panted, and tears glimmered in his burning red eyes.
"Please Deku. Deku! Let me touch you. Fuck- Touch me Deku! D-degrade me, I want you to be mean to me! Let me be good and make you feel good! Deku! Please! Izuku!" Katsuki rasped, teary eyed.
Izuku shuddered. "God Kacchan, I never thought I'd hear you sound so slutty." He held the base of his cock to ground himself.
"How do you want to make me feel good Kacchan?" Izuku asked.
Katsuki gave Izuku a look.
"Nothing penetetrative, we agreed! something besides that Kacchan." Katsuki pouted.
"Wanna suck you." Katsuki replied bluntly.
"You know I want you to ask nicely for things Kacchan." Izuku chided.
Katsuki crawled forward between Izuku's legs and rested his head on his boyfriend's thigh with one hand on each. "Need to suck you off Deku. Can I? Please?"
"Shi- Yes Kacchan, good boy." Izuku gripped Katsuki's shoulder with one hand the sheets with his other. Katsuki began immediately. He started licking and suckling at Izuku's balls before gently dragging his teeth across them in the way he knew drives him crazy. Then he licked one long pathway to the tip, swirling his tongue around it. Once. Twice. Three times before he looked Izuku in the eyes, and sunk his head down as far as he could.
"Ahhh! Nnngh! Kacchan!" Izuku moaned, and so did Katsuki.
"God Kacchan. You made that begging of yours so filthy and desperate. It's like Ahh whevever you are about to get your dick wet you become a dumb slut. Desperate and brainless, just pumping your dick 'til you finish without thinking of anything else. Even now when you're -Ah ahh nghh- making me feel good, it's because me talking down to you like this makes you feel even better, right?"
Katsuki was far too occupied and far too overwhelmed to truly respond. Bobbing his head, hollowing his cheeks, and moaning while frantically humping the bed. Whining and licking and sucking and drooling, all while his cock strained in his pants begging for friction against Izuku rather than his own matress. His eyes were clouded over, as the tears were free falling, and his hands began heating with his quirk.
Izuku moaned. "Kacchan?" Izuku tried to catch his attention but Katsuki just sucked him down deeper.
"So cock hungry you can't even respond?" He asked again and he noticed that Katsuki's thrusts against the matress got faster.
Izuku moved one hand to grip into Katsuki's hair, hard. Then he yanked Katsuki's head away from his cock, a trail of saliva connected his tougue from the tip and as it fell against Katsuki's chin Izuku groaned.
"Hah? Deku? Why?" Izuku jerked Katsuki's head back, and he let out a high pitched moan.
"I was talking to you mister." Izuku smiled. "We're going to change things up just a little bit. First move so that you are resting on your knees rather than lying down, and hold your hands behind your back. You didn't ask me permission before humping the bed, so now your cock will have to wait."
Katuki moved into the position and whined.
"Now I'm going to keep my hand in your hair, and i'm going to fuck your slutty face until i'm ready to cum on it. If I go too hard or you want to stop, I want you to bring your hands back down and slap my thighs hard. Any objections?"
"Yeah..." Katsuki began, dazed. "Shit I mean no objections. If I stop liking it I slap your thighs, got it. Just want you to keep pullin' my hair, fuck it feels so good, when you did it I almost- so... P-please?"
"Of course Kacchan. Look at you, asking nicely without being told. Good boy."
Before Katsuki could finish a moan, he was shoved back onto Izuku's dick, with his hair caught in a vice like grip, as his mouth was used .just the way he wanted.
Izuku started tortutously slow, teasing both Katsuki and himself, loving the way it made them both shudder, but as Izuku's grip in his hair tightened, Katsuki moaned louder.
The vibrations, the noise itself had an immediate effect on Izuku. He groaned and fisted his boyfriend's hair tighter, he pulled the blonde off if his cock again and he gave his instructions.
"Don't move or speak and keep your mouth open." Izuku shifted and folded his legs beneath himself so he was on his knees. "Fuck Kacchan you're so hot."
Katsuki's loud moan was once again interupted by Izuku thrusting into his mouth at an incredibly fast pace, the shift in position meant he had more control over how he moved into Katsuki's mouth and he took advantage whole-heartedly.
He aimed up into the roof of Katsuki's mouth knowing that he would gag around his cock as a result, and as he pushed down deeper into Katsukis throat it would squeeze him with every thrust and they both quaked with the motion.
Katsuki resisted the urge to fist his cock. It ached and throbbed still restrained by his pants and he loved it. This experience is something straight out of his wet dreams and Deku was just giving it to him like it was no big deal. He took Izuku's hand that wasnt in his hair and entertwined their fingers. He squeezed his hand before bringing it into his hair to make Izuku grab his head with both hands. Izuku groaned.
Izuku somehow got faster as his orgasm approached, heat joltwd and coiled around his insides and he whimpered. "K-Kacchan Ahn Ngh God i'm so close! You suck me so good! So filthy and whorish an- and i'm going to- Ah Ngn I'm going to cum Kacchan!"
Izuku yanked Katsuki's head back hard, moved one hand back to the base of his dick and he rubbed once, twice, and then they both moaned as he came on Katsuki's cheeks, chin and tongue from his open awaiting mouth.
Izuku stared at his boyfriend. The sweat that trickled smelled like caramel, and made strands of his pale hair stick to his forehead. His pupils were blown wide in bliss and his rich carmine eyes were misty, as fat tears forced their way out of them. His eyebrows were furrowed, his mouth hung open and his tougue lolled out of his mouth, covered in drool an Izuku's cum, and all of this was accented by a red blush that bloomed across from ear to ear.
Izuku leant down and kissed Katsuki's forehead. "Beautiful."
Katsuki's moaned and swallowed, but cum remained on his cheeks. They were both more than fine with that.
"Deku, Izuku, Izuku please, please? Fuck! I need to cum. Can I? Please can I make myself cum Deku? Please fuck, please let me please!" Katsuki sobbed desperately.
Izuku groaned, knowing that begging would be enough to get him hard if he handn't just cum so intensley.
"Of course you can Kacchan, you made me cum so good. So good Kacchan. How do you want it? Hmm? You want my mouth? My hand?" Izuku asked as he guided Katsuki to sit with their chests flushed against each other and he pressed gentle kisses to his neck.
"I wanna... I... Fuck I wanna grind on your thigh! I wanna- please I want you to hold my hands behind my back and talk me through it! Can I? Please can I cum while I ride your thigh Deku?" Katsuki begged.
Izuku bit his lip and lifted Katsuki's legs so that he was straddling his thigh. Then he grabbed both of Katsuki's arms that he had against his back and held them with one hand pushing Katsuki closer to him.
"Kacchan that was so, so good. Of course you can." Izuku cooed.
Katsuki sobbed and quickly began his humping and grinding. He leant into Izuku's neck. "Thank you! Ngh Thank you Deku, fuck thank you so m-much Ah Ngh..."
Izuku groaned in frustration as this was easily the hottest experience of his life but he had just had the orgasm of the century. He knew he wouldn't be able to get it back up, but he figured he can try and return the favour.
Izuku wrapped his free hand into a gentle fist, lightly tugging blonde spikes just enough to sting the way his boyfriend apparently liked. He leaned into Katsuki's neck and pushed his teeth into him. Katsuki moaned.
"Kacchan that was so amazing. You made me cum harder than I ever had, it was so, so good." Katsuki's humping became faster and his moans bacame guttaral. He was getting close.
"The way you begged to suck my dick, and begged me to degrade you. You were so slutty. The prettiest slut. And when you humped the bed like some kind of animal? You acted like such a bitch Kacchan. Such a desperate little bitch for me baby."
Katsuki sobbed racked through both of their bodies. His eyes widened and more tears flooded out of him. He was almost there the pleasure and humiliation overwhelming. The heat in his abdomen had spread through his entire body.
"Gotta! Ngh Need to cum! Please Ahh! Fuck Deku can I? I was good! Wasn't I good? Please- Ngh fuckin' please can I cum?" Katsuki quaked as he begged.
Izuku trembled. "Of course you can cum, Kacchan you were perfect."
"FUCK! Aghhh Ngh AHHN! AHH! Thank you! Thank youthankyouthankyou..." Katsuki screamed and rode through his orgasm, as Izuku rubbed his back and whispered praises into Katsuki's ear.
Finally Katsuki slumped into Izuku, resting his eyes and panting to catch his breath.
"How was that Kacchan?" Izuku asked nervously.
Katsuki growled through his panting. "Don't... don't you get all shy on me now nerd. Clearly I enjoyed myself." He buried his head deeper into Izuku's chest, hoping somehow he may disappear there, the shame of post-nut clarity hit him hard.
"T-then you can't get shy now either! That was the hottest sexual experience I've ever had, and you weren't even inside me! Being in charge of Kacchan was a cathartic experience, and so hot. Next time I absolutely want you Kacchan to submit to me, while being inside me. That would be..." Izuku trailed off into incoherent mumbling and Katsuki gaped.
"Next time?!" Katsuki yelled, pulling away from Izuku's chest.
Izuku's mumbles stumble and halt. "Well yeah? Unless... Oh gosh, was this a one time fantasy for you? Or did I not do a good enough job? Did I go too far? Was it-"
"Deku!" Katsuki interrupted with both hands coming up to squish Izuku's cheeks."Let's get this straight cause your dumb ass is clearly thinkin' to damn much. That was the best. You were better than I dreamed you would be at this literally. And I would love to do this again. Just didn't think you would wanna. I thought you'd think it's weird."
"Of course not Kacchan! That was amazing! You were amazing! We need to do some research, but I definitely want to do this again!"
Izuku flopped backwards into his boyfriend's matress and sighed.
"Being in charge of Kacchan was super fun, you barely ever listen to me." Izuku giggled.
"Yes I fuckin' do! I just don't to stupid shit just cause you batted your pretty lashes at me." Katsuki smacked Izuku's arm playfully from his upright position.
"There's nothing stupid about telling you to lay down and cuddle with me is there Kacchan?" Izuku smiled sweetly.
"..."
"..."
"We need to get cleaned up Deku." Katsuki sighed.
"Aha!" Izuku jolted upright, and squeezed his boyfriend in a bear hug. "Excuses, excuses Kacchan."
"... Deku."
"Yes Kacchan?"
"Your jizz is drying on my face." Katsuki deadpanned.
"EEP I'M SO SORRY!" Izuku immediately pulled away and grabbed an obnoxious amount of tissues from the nightstand clean Katsuki's face.
"Pfft- Hahaha." Katsuki chucked deeply. "We'd better leave the whole 'in charge' business to me for now Deku."
Izuku pouted "For now."
Katsuki kept laughing. "Yeah for now and y'know, just most of the time."
"When we get cleaned up we can cuddle right?" Izuku asked eagerly.
"Only if you ask nicely nerd." Katsuki stuck his tongue out.
Izuku leant forward and kissed Katsuki deeply, biting his botttom lip, before leaning back, and licking his own lips.
"How's that for nice Kacchan?" Izuku smirked.
Katsuki went red, he wrestled Izuku down into the sheets before cuddling him close.
"Good boy Kacchan." Izuku squeezed around Katsuki tightly.
"Well you know the saying, 'Ask and you shall receive."
