Summary: Bakugo forces Izuku to sit through class with a dildo in his ass. Aizawa, obviously, notices. Since Izuku is just so stupidly cute, he decides to have some fun

Just a few more minutes. He just needed to hang on for a few more minutes! Hands clenched into tight fists, blunt nails digging into his calloused palms, Izuku struggled to stop himself from repeatedly glancing at the clock as it slowly, so very slowly, ticked by. Aizawa-sensei had already scolded him for not paying attention twice during the lesson. His classmates kept glancing at him, their expressions ranging from concerned to confused to amused. Right now, he didn’t want to bring any more attention on himself – not when this embarrassing nightmare was nearly over. It was already impossible to hide how flushed his face was, as well as how violently his body was trembling. The only silver lining in this was that no one could see underneath his desk. Otherwise, they would’ve had the expected question of: why the hell was he erect in class? Swallowing against the dryness in his throat, Izuku made the mistake of shifting slightly. Biting down hard was the only way to hold back the sharp cry that came bubbling up his throat as an intense shockwave of pleasure radiated out from his tingling backside.

Sucking in a shaky breath, furiously blinking away the tears that welled up in the corner of his eyes, Izuku furtively glanced at the clock once more. To his immense relief, five minutes had jumped down to one. Both hands moved steadily towards the goal. Aizawa-sensei’s lesson, which he normally would pay close attention to, turned into incoherent rumbles in his ear. Thirty seconds…twenty…fifteen…ten…five-! The bell rang loudly, finally signaling the end of the class. It took all of his willpower to not jump to his feet and rush from the classroom. Gripping tightly onto the edge of his notebook, Izuku silently watched as his classmates gathered up their stuff, filing in groups or one by one out of the double doors. Within a matter of moments, he, Kacchan and Aizawa-sensei were the only ones left. Despite his best efforts, Izuku fidgeted anxiously in his seat, impatiently begging Aizawa-sensei to leave already.

To his dismay, instead of taking off as soon as everyone else was gone, as he usually did, Aizawa-sensei walked over to him, staring down at him with a curious gaze. He stopped beside his desk, his hands pushed deep into his pockets.

“Do you want to tell me what’s going on?” He asked, his voice a low rasp.

“W-What?” Izuku squeaked, sounding far more panicked than he had intended.

Sighing irritably, Aizawa-sensei gestured vaguely at him, “All this. What’s wrong with you?”

“N-Nothing! I just-!”

“Oi, Sensei.” Kacchan spoke up from in front of them. He turned in his seat, grinning broadly, a mischievous spark dancing in his bright red eyes, “I know what’s going on with him.”

“Oh? And what is that?”

“Ka…Kacchan, wai-“ Izuku weakly protested, a pang of cold horror piercing through his chest. There was no way…he couldn’t be planning on-!

Getting to his feet, Kacchan swaggered over to them. Aizawa-sensei stepped out of the way, watching them both with that same curious look. One large hand lashed out to grab hold of Izuku’s arm, roughly wrenching him out of his seat. Izuku cried out in alarm and embarrassment, his hands immediately flying down to cover his noticeable bulge. It turned out to be a useless motion. Before he had time to register what was happening, Kacchan had his pants unbuttoned and down around his ankles, allowing his sopping wet, twitching erection to bounce free. He plopped down onto Izuku’s desk, pulling him into his lap. Large, hot hands slipped underneath his knees, yanking his legs up and open, completely exposing his ass. Izuku’s eyes bulged. His heart plummeted like a chunk of ice down into his belly. He desperately tried to cover himself but it was too late. Aizawa-sensei had already seen it: a vibrating dildo, going full speed, pushed deep inside his hole. Sobbing miserably, tears streaking down his scorched cheeks, Izuku tried to gasp out an explanation – something, anything that could make this a little less worse – but no words would come out.

“What do you think, Sensei?” Kacchan purred, grinning slyly up at Aizawa-sensei.

Slipping one hand down to his ass, Kacchan pressed his fingers against the hilt of the dildo, pushing it in a bit deeper. There was no stopping the loud, wet gasp that wrenched itself free from his mouth. Clapping a hand over his mouth, nauseous with embarrassment and horror, Izuku did his best to curl in on himself but Kacchan grabbed hold of his jaw with his other hand, yanking his head back up so he was forced to look Aizawa-sensei in the eye. To his dismay and horror, there was no trace of disgust on Aizawa-sensei’s face. Two bright spots of red burned in his scruffy cheeks. Staring back, wide eyed, hardly able to get a breath in, Izuku quickly glanced down to his crotch. His bottom lip began to tremble. Fresh tears welled up in the corner of his eyes. There was a noticeable bulge between Aizawa-sensei’s legs. Aroused…his own teacher was getting aroused from seeing him like this? Izuku’s gaze flickered back up Aizawa-sensei’s face, shrinking back a little when he met those dark eyes. Aizawa-sensei…he was looking at him the same Kacchan did right before he was about to use him like he was just a toy meant to make him cum.

Chuckling low in his throat, Kacchan teasingly nipped at his earlobe, forcing a shiver. Curling his fingers around the hilt of the dildo, he abruptly yanked it out. Izuku wailed loudly, his cock twitching and pulsing, a spurt of precum splattering onto his belly. Tossing the still vibrating dildo onto a nearby desk, Kacchan sunk three fingers deep into him, spreading them open to stretch his sloppy hole. An immense shriek of pleasure smashed its way through his body, dragging him even closer to orgasming. Izuku sobbed and moaned, writhing in Kacchan’s hold. No-! He…he didn’t want to be made to feel good in front of Sensei-! “He’s cute, isn’t he?”

“What the hell do you think you’re doing my class, Bakugo?” Aizawa-sensei asked in a rough voice, even as he was stepping in closer. One large hand rested on Izuku’s trembling thigh. He gasped sharply in response, attempting to jerk his leg away. There was nowhere for him to go, leaving him stuck between Kacchan and Aizawa-sensei’s imposing form. His other hand wandered down to where Kacchan’s fingers were messing with his ass. A shock raced through his body when one of his long digits pushed in alongside Kacchan’s. Eyes bulging, another deplorable wave of pleasure crushing him, Izuku tried to grab Aizawa-sensei’s wrist to pull him out but couldn’t find the strength.

“Having fun.” Kacchan replied, as though it was the most obvious thing in the world. He paused for a moment then grinned widely once more, “He’s gotten through the entire class without cumming. See?” Kacchan gently brushed the tips of his fingers against the head of his cock, soaked with precum but with no trace of semen anywhere, wrenching another, wetter gasp out of him, along with a hard, unconscious buck of his hips, “We should reward him, shouldn’t we, Sensei?”

“K-Kacchan, please…” Izuku whimpered.

Cocking his head slightly, Aizawa-sensei pressed in even closer. He leaned down, brushing the tip of his nose against Izuku’s scorched cheek, inhaling deeply “What did you have in mind?”

“Sensei!” Izuku cried desperately but it was as though he couldn’t even hear him.

Instead of answering, Kacchan slipped his now drenched fingers out of Izuku’s twitching hole. He dropped his hand down to tug open his trousers, dragging out his rock hard, burning hot cock. Without breaking eye contact with Aizawa-sensei, Kacchan lead the bulbous head to his entrance, lifted him up slightly then slammed his hips upwards, driving his cock deep inside. Izuku let out a ragged, shrill wail. White washed across his vision. Despite his mortification at being fucked in front of Sensei, the pleasure of finally being stuffed full of Kacchan’s thick, fat cock wasn’t at all dulled. If anything…it…it felt stronger than normal. Sobbing bitterly, his mouth hanging open, Izuku knew there was no escaping but that didn’t stop him from trying to get away. He didn’t want this-! He didn’t want Aizawa-sensei to see him like this-! Like…like he was a slave to Kacchan’s cock-!

“Come on, Sensei.” Kacchan panted into his ear, “You wanna reward him too, right? Then give him what he wants.”

Audibly swallowing, Aizawa-sensei seemed to jerk out a stupor. In a quick, smooth movement, he had the front of his jumpsuit open. Shoving a hand inside, he pulled from the fold of a fabric a fat cock that was much bigger than Kacchan’s. Izuku’s eyes widened at the sight of it. His breath caught in his throat, choked out by a wave of cold dismay and despicable excitement. Digging his blunt nails into the smooth skin of his inner thigh, Aizawa-sensei brought the head of his cock to Izuku’s already stuffed full entrance. Just as the realization of what was going to happen managed to wriggle through the dense fog that had started to overwhelm his mind, Aizawa-sensei rammed his hips forward, shoving his cock in alongside Kacchan’s. A scream slammed into the back of his clenched teeth, coming out as a strangled whimper. Neither one gave him any time to adjust. Both started to move in viciously rough thrusts, slamming into him with enough force to make him bounce in Kacchan’s hold. The sudden sensation of being so suddenly stimulated in such an extreme way was too much for him to take.

“CUM-!” Izuku forced out through the gaps in his teeth. Every muscle in his body tensed up. The back of his head slammed against Kacchan’s shoulder. His hips strained upwards as heavy ropes of white sprayed out of his cock. Despite his embarrassment, despite the shame, despite knowing that one of the cocks pounding into him was that of his teacher’s, this still…it felt so good…it felt so incredibly good-! Deep-! So deep-! Both of their cocks were stretching him impossibly open-! He was stuffed so full-! This…this was completely different from being fucked by a dildo or just Kacchan’s cock! It…it was too much-! Clinging to the front of Aizawa-sensei’s jumpsuit, unable to hold back the cries, wails and moans bubbling out of his throat, Izuku tried to shove him away, terrified by the mad pleasure tearing through him, setting every nerve in his body alight. No more-! He couldn’t take anymore-! It was too much-!

“Break-!” He sobbed, “You’re-! You’ll break me-! Please-! Stop-!”

“Is he always this noisy?” Aizawa-sensei rasped huskily, pushing in to lick up one of Izuku’s tears.

“Yeah, usually.” Kacchan laughed, “Don’t mind it. He tries to hide how much of a slut he is but really,” he grabbed hold of Izuku’s jaw, turning his head over so he could press a sloppy kiss to his trembling lips, “he loves it…being held down, humiliated, degraded, used and abused.”

“No-!” Izuku frantically shook his head.

“Good to know.” Aizawa-sensei panted, a lopsided smile spread across his flushed, sweaty face. His dark gaze, swimming with restrained lust, flickered up to focus on Kacchan, “You do realize I can have you kicked out of school for this?”

“Yeah, but you won’t. Because now, you want to use him just as much as I do.” Kacchan squeezed Izuku even closer, “So, what do you say, Sensei? Wanna share him?”

“Don’t ask stupid questions.” Aizawa-sensei retorted, “And shut up – let me enjoy our new toy without your incessant chatter.”

“Sensei…” Izuku whimpered pathetically, “Ple-!”

Before he could finish his desperate plea for mercy, Aizawa-sensei lunged down, wrenching his head back over to smash their lips together in a possessive kiss. The subtle taste of applesauce and coffee spread over his tongue as Aizawa-sensei devoured his mouth. Izuku went limp in their hold. There was no getting away from this, was there? These two were going to use him as their personal playing and he…no matter how much he tried to hate it, he was going to enjoy every moment of it. It…it just felt too good…being kissed, being fucked, touched, messed with, played with – he hated it but he…he wanted even more…Tears streaked down his cheeks. His chest heaved with weak sobs. He wanted to run, to hide, to put an end to this endless humiliation. Yet he knew…there was no escape for him. That alone was enough to chill him to his core but what scared him even more was this incessant, gnawing desire that demanded more.

“Whatever you say.” Kacchan just laughed, happily nibbling on the curve of his throat.

“Ka-!” Izuku gasped against Aizawa-sensei’s lips.

“Hush.” Aizawa-sensei murmured, leaning back to hold him captive with his dark gaze, “Be a good boy and do as your told. Do that, and I’ll show you how adults use their toys.”

Curling his thin, calloused fingers into Izuku’s fluffy hair, Aizawa-sensei leaned in once more to capture his mouth in another rough kiss. Whimpering low in his throat, his eyes fluttering closed, Izuku distantly wondered what was going to happen to him but the moment that thought managed to gain traction in his mushy mind, his two masters started to move in sync together again, smashing all of his trepidation in a brutally massive wave of ecstasy.
