Summary: Just literally Aizawa loving his Deku

-

The teachers’ lounge was empty, save for the familiar figure bent over his desk, slowly shuffling through a stack of tests. A thick sheet of inky hair hung around his shoulders, partially obscuring his scruffy face. Soft, warm sunlight filtered in through the wall of windows. The air conditioner rattled quietly from its perch in the farthest window to the right. Outside, the sky was a stunning shade of blue, stretching out as far as the eye could see. On an afternoon like this, he might’ve been getting some extra training in after school…but there was something far more important waiting for him in this very room. Deku slid the door shut behind him, his gaze glued to Aizawa-sensei’s form. With no one else in the room, there was nothing else marring Aizawa-sensei’s scent. Standing in the doorway, his scarred hands wrapped loosely around the straps of his backpack, Deku inhaled greedily. His heart fluttered as the alluring scent of apples, sweat and menthol flowed into his lungs.

He could’ve stood there for hours, listening to the comforting sound of Aizawa-sensei’s pen moving across the page, breathing in his addictive scent, basking in the temporary, precious peace…but that didn’t sound anywhere near as enjoyable as what he was actually here for.

Shifting his backpack off his shoulder, he hung it up on the nearby coat hooks. The sound, while not loud at all, was enough to catch Aizawa-sensei’s attention. Raising his head from the tower of test papers, he turned bloodshot, exhausted eyes, rimmed with dark circles, his way. The moment their gazes met, all the tension visibly fled Aizawa-sensei’s larger, toned body. A warm smile spread across his scruffy face. Letting out a pleased, relieved sigh, he let his pen drop onto the desk. It rolled across the pages, completely forgotten now that Aizawa-sensei’s attention was solely on him. Izuku couldn’t help but to beam as well, a welcoming bloom of love and warmth swelling up inside his chest. His breath caught. The tips of his fingers tingled pleasantly. It didn’t matter how many times they met like this, seeing Aizawa-sensei practically melt at the sight of him…it always made him feel a little drunk with happiness.

“There you are.” Aizawa-sensei rasped, languidly raising from his chair, “Aren’t you a sight for sore eyes.”

“I came as soon as I saw your text.” Izuku replied with a wide smile, “I thought you’d be busy.”

“I am but…” Aizawa-sensei laughed, wearily scrubbing at his face. When he dropped his hand away, the corners of his lips were tilted up in a sly smile that made Izuku’s heart flutter, “Lot of stuff going on. I need to recharge and what better way to do that than showering my little bunny with love.”

The mention of Aizawa-sensei’s pet name for him sent a delighted shiver racing down his spine. Tingling heat dusted his round cheeks, curling down to wrap around his jaw and throat. It always felt a little unreal to hear the brash, forward Aizawa-sensei call him something like that but, at the same time, it made him giddy to know that he was the only one who got to see this side of their hard-ass teacher. Bashfully dropping his head, Izuku fiddled with the hem of his shirt, murmuring, “I…I thought you might be stressed so I’ll work hard to-“

“There’s no need for that, little bunny.” Aizawa-sensei purred, striding across the room.

His dark gaze swam with vibrant heat. He stopped in front of him, leaning down to gently brush the backs of his fingers along the rounded curve of his cheek. Pushing in even closer, he placed a sweet kiss onto the corner of his lips. Izuku gasped softly, reaching up to curl his fingers into the front of Aizawa-sensei’s jumpsuit. A burst of tingles radiated out from where Aizawa-sensei’s smooth, firm lips were pressed to his skin. Izuku turned his head slightly, whimpering. This…this wasn’t enough. He wanted a real kiss…! Smoothing his scarred hands along the curve of Aizawa-sensei’s ribs, Izuku followed the line of his spine up to his neck, threading his fingers through his silky hair. Tilting his head back slightly, he looked up at Aizawa-sensei through thick lashes.

“Tell me what you want, little bunny.” Aizawa-sensei cooed, pressing their foreheads together. Those warm, dark eyes peered lovingly into his own, almost imploring him to be honest.

“Kiss…” Izuku whispered, his heart fluttering against his ribs. The heat humming in his face became even more intense, spreading from the tips of his ears to his collarbone. He had to be as red as Kirishima-kun’s hair by now. If anyone else were to see him like, he would’ve been so embarrassed that he wouldn’t be able to look them in the eye but…Aizawa-sensei effortlessly made him feel comfortable, confident, “Can…Can I have a real kiss?”

“Oh, my little bunny, of course. I’m sorry to keep you waiting.” Curling his arms tighter around him, Aizawa-sensei pushed him even closer, his lips hovering directly over Izuku’s. Warm breath brushed across his skin. Moaning softly, Izuku fought against the urge to push forward and take a kiss for his own. He knew he wouldn’t mind but he…he wanted Aizawa-sensei to kiss him. Brushing the pads of his thumbs over his blisteringly hot cheeks, Aizawa-sensei tugged him forward, “Come here.”

“Sen…” Izuku breathed, just as Aizawa-sensei pressed his warm, smooth lips to his in a firm kiss.

The kiss remained chaste for only a moment before Aizawa-sensei knotted his long, calloused fingers into his hair, holding him close as he hungrily devoured his mouth. Izuku’s eyes fluttered closed. When the tip of Aizawa-sensei’s tongue bumped against his teeth, he eagerly spread them to let it inside. The sweet taste of applesauce flowed across his tastebuds. The rough scruff along Aizawa-sensei’s jaw rubbed against his skin, creating a ticklish sensation that he couldn’t get enough of. Moaning sweetly, Izuku pushed back into him, returning the kiss to his best ability. He was still so clumsy, blindly following Aizawa-sensei’s lead as best he could. Thankfully, it seemed that his efforts didn’t go unnoticed.

Letting out a rumbling growl, Aizawa-sensei dropped a hand to his ass, giving the plump globes an appreciative squeeze. Izuku gasped into his mouth, eagerly pushing his butt back against Aizawa-sensei’s palm. A burst of heat ricocheted up his spine, sending out sparks that wove through his nerves, creating a network of tingles that threatened to make his knees buckle. His cock twitched inside his underwear, quickly hardening underneath the attention Aizawa-sensei was showering on his backside. Still…he wanted more…! This over the clothes stuff wasn’t enough. He…he wanted Aizawa-sensei to make a mess of him…to fuck him until he couldn’t walk straight for a week. He wanted to walk back to the dorms with his cum dribbling down his thighs. Izuku swallowed down the excess drool that had been accumulating underneath his tongue. He…he couldn’t wait. He wanted it right now…he needed Aizawa-sensei’s cock inside of him!

It seemed he wasn’t the only one who came to the same conclusion. After giving his ass another fond squeeze, Aizawa-sensei broke away from the kiss with a sharp gasp. A thick strand of saliva kept them momentarily connected before breaking into a splatter across his lips. Smiling warmly, his dark eyes blazing with lust, Aizawa-sensei gave his ass a gentle spank, pulling a startled squeak out of him. His cock throbbed, dribbling more precum into his now soaked underwear. His hole itched, tightening and spasming as that desperate desire to be pinned underneath Aizawa-sensei’s body became even more intense. Just as he was opening his mouth to spew what would’ve definitely been an embarrassing plea, Aizawa-sensei stepped back. He took hold of Izuku’s elbow, tugging him backwards, towards his desk.

“Do you know what I want right now, little bunny?” Aizawa-sensei asked, his voice a low, husky rasp.

“I…I can guess, sir.” Izuku replied shyly, a trembling smile stretched across his face. Right now? Here?! They…they had done it in public before but never in such a…conspicuous place! There shouldn’t be anyone around right now…he hoped. Izuku resisted the urge to shake his head. No, he didn’t want to think about that. He wanted to focus solely on Aizawa-sensei, just like he knew he wanted him too.

Aizawa-sensei chuckled, “Oh, I want that but there’s something else, little bunny.”

His back bumped against his desk. He tugged Izuku forward then spun him around so he was the one pushed up against the smooth wood. One of his large hands dropped down to push between his thighs, giving his aching cock a loving squeeze. Izuku moaned loudly, his hips bucking forward. Sweat rolled down his forehead, soaking into his eyebrows. Thick locks clung to the nape of his neck. Smiling hungrily, his dark eyes gleaming, Aizawa-sensei stroked him through his pants, intently watching him as he trembled underneath his touch. Crap…crap! He wasn’t even touching him properly but it was already feeling so dangerously good! If this kept up, he might cum before they even got to the good part!

“P-Please…!” Izuku gasped, weakly grabbing hold of Aizawa-sensei’s arms, “Ai-Aizawa-sen-!”

“Ah, ah, ah.” Aizawa-sensei cooed, purposefully rubbing the pads of his fingers firmly against the tip of Izuku’s clothed dick. He gasped wetly, tears welling up in the corners of his eyes. Good…good, good-! He…he didn’t want to cum like this-! He wanted to cum with Aizawa-sensei inside him-! Pushing in even closer, bringing his mouth right next to Izuku’s ear, Aizawa-sensei breathed, “That’s not what I want to hear when we’re alone…just the two of us.”

Dragging his tongue along the shell of his ear, Aizawa-sensei whispered huskily, “I want to hear it, Izuku.”

Shuddering at his warm, honeyed voice flowed into his head, wrapping his synapses up in a golden fog, Izuku hesitated for just a moment – the heat blazing in his cheeks even more intense than ever – then choked out on a ragged breath, “P…Please…Daddy…fu…fuck me…”

A harsh breath rolled against his ear. Growling low in his throat, Aizawa-sensei spun him around, pushing him down so he was bent over the desk. His butt snugly smooshed against Aizawa-sensei’s crotch. An electric jolt radiated up his spine, ending up as a burst of vibrant sparkles inside his mind. Daddy’s cock! Daddy’s cock-! He…he was so hot, so hard already-! He could feel how much this thick thing wanted to be buried inside of his sloppy pussy. Izuku moaned needily, shaking his hips to grinding against that hot bulge pushing between the plush cheeks. Him too…him too-! He wanted that incredible length inside him-! He wanted his Daddy to fuck him! He wanted his Daddy to pump his belly full of his cum! Rough pants rained down onto the top of his head. Aizawa-sensei grabbed the hem of his pants, yanking them down to expose his ass. Hot breath rolled across the sensitive skin. Aizawa-sensei pressed his tongue to the roundest part of the curve, drawing it down further as he spread him open.

Wet heat pressed to his twitching hole. Izuku gasped sharply, his head jerking up from the desk. Precum dribbled from his cock, splattering across the floor between his feet. Daddy’s tongue-! It…it felt so good-! Curling his strong hands around his trembling hips, Aizawa-sensei lapped and rubbed his tongue across his hole, coating the delicate skin in a heavy layer of saliva. He pressed the tip to the puckered entrance, easily wiggling it inside. Izuku let out a loud moan, happily wiggling and shaking his hips as Aizawa-sensei’s tongue slipped further in. The talented muscle swirled around inside of him, stroking across the spasming interior walls. Gasping wetly, raising up onto the tips of his toes, Izuku pressed his ass back against Aizawa-sensei’s face. One of his thin hands slipped between his trembling thighs to wrap around his aching, sopping wet length, giving it a strong pump.

“D-Daddy-!” Izuku choked out, all the strength fleeing from his legs.

Moaning low in his throat, Aizawa-sensei slid his tongue out of his twitching hole to breathe, “You taste so good, little bunny. I can’t get enough of this sweetness…I love it so much…”

“Please-!” Izuku whined as Aizawa-sensei’s tongue dragged across his entrance. “Please-!”

“What do you want, my little bunny?” Aizawa-sensei cooed, “Tell me…I’ll give you everything you want.”

“Your cock-!” Izuku gasped, “Please-! Daddy! Your cock-! Your cock-!”

He felt Aizawa-sensei shudder behind him. Sucking in a sharp breath that whistled through his teeth, he chuckled huskily, “Oh, you know how to rile me up, my little bunny.”

Straightening up, Aizawa-sensei curled his hand lightly around the back of his neck, weaving his longer fingers through his hair. The quiet, subtle sound of a zipper being undone sent a jolt rolling through his body. After a beat of stillness, something hot, very and wet pressed firmly to his entrance. An exhilarated gasp rippled out of his throat. Moaning needily, Izuku was about to push back against him, hoping to tease Aizawa-sensei into being a little bit rough with him, when those powerful hands grabbed hold of his waist, yanking him upwards so his feet were dangling off the floor. Aizawa-sensei growled, an almost primal, feral sound that sent a rage of heat howling through him. Usually, these little rendezvous were a little gentler, sweet but today, there was a harsh edge to Aizawa-sensei’s breath. He could feel his hands trembling. Izuku’s eyes widened. Was today the day?! Was Aizawa-sensei finally going to fuck him like he’d always wanted him too-?!

Just as that thought was flashing across his mind in huge, vibrant colors, Aizawa-sensei forcibly rammed his hips forward, driving his thick, fat length past the tight ring of muscles to sink deep into his spasming hole. Izuku’s head flew back. A loud, keening squeal poured out of his gaping mouth. If he had been standing on his own two legs, he would’ve collapsed. Intense, boiling, rupturing heat poured out from the base of his belly, originating exactly where that big thing was stretching him open. A delirious grin spread across his brightly flushed face. He scrambled to grab onto the edge of the desk as Aizawa-sensei began to rapidly buck his hips, fucking him with enough strength to send him jolting forward every time their bodies colliding. The sound of the humming air conditioning was completely overwhelmed by the wet squelch of his hole being pound, the harsh moans rumbling out of Aizawa-sensei’s chest, and his own high pitched squeals.

“You’re taking my cock so well, little bunny. It feels incredible inside you…” Aizawa-sensei bent down to pant roughly into his ear, “Be a good boy and tell me…does it feel good?”

“Good-! Good-! Daddy-! Daddy-! More-! More-! Fuck me…fuck me harder-! More-!” Izuku wailed, doing his best to hook his feet around Aizawa-sensei’s legs.

Chuckling low in his throat, Aizawa-sensei whispered, “Such a sweet, beautiful voice. Will you let me hear even more, little bunny? I can’t get enough…I want to hear even more. Don’t hold back. Let me hear everything…”

“D-Daddy…!” Izuku gasped, vibrant glee bubbling up inside his chest. He was always talking about how much he loved hearing him when they did something like this but to Izuku, Aizawa-sensei’s voice was so much more gorgeous. That low rasp, the honeyed rumble…he sometimes thought he could come from just that, “Love-! Love your cock-! More…please, Daddy! Please-!”

“Me too…” Aizawa-sensei whispered, nuzzling against the side of his head. One of his large hands smoothed down from the curve of his waist to firmly grope his ass, “This hole…I’m addicted. I don’t think I’ll ever get enough. Every time we do this…I get even hungrier.”

Aizawa-sensei laughed softly, rolling his hips to grind his length against the interior wall of his ass, pulling a strangled gasp out of Izuku, “It worries me a little. Some days…the thought of not holding you like this drives me crazy. I want you always…Just a smile and I’m done for. It takes all my control to keep my hands off you…”

“You…you can use me whenever you want, as much as you want…!” Izuku twisted around as best he could to pepper wet kisses across Aizawa-sensei’s scruffy cheek, “I’m yours-! I’m yours-!”

“I know, little bunny.” Aizawa-sensei cooed, “But you need to remember: I’m still your teacher. I won’t have your studies suffering because I can’t control my hunger.”

Before Izuku had a chance to try to further convince him that it really was alright for him to fuck him whenever he wanted – not like he was ever going to complain – he straightened back up. Sweat dripped off the line of his jaw, plopping down onto the small of Izuku’s back. He pushed his long, dark hair out of his face. A sly grin spread across his flushed face. Dark eyes, gleaming with lust, roamed over his trembling body, seeming to devour every inch of him. Swallowing hard, Izuku clumsily rolled over onto his back. It took a couple moments of struggling to make his sluggish body move but, with a little help from Aizawa-sensei (who was doing a really bad job at hiding how amused he was), he managed it. Letting out a long, shaky breath, his head spinning with dizzying heat, Izuku hooked his hands underneath his knees, pulling his legs up and apart. His throbbing, aching cock stood straight up from a mess of drenched pubic hair. The fact that he hadn’t cum yet was, hopefully, a sign that his endurance had gotten better. Normally, he couldn’t hold on for this long!

“Gotta make the best of our time. Isn’t that right, my little bunny?” Aizawa-sensei breathed, curling one of his large hands around Izuku’s length. He moved forward a little, causing his cock to slip deeper inside of him. Moaning softly, a jolt racing through his body, Izuku reached out to snag the front of Aizawa-sensei’s jumpsuit.

“Y-Yes…Daddy, I wanna…be your good little bunny…so p…please…use me as much as you want…”

Bending down to press a sweet kiss to his drool drenched lips, he whispered, “Such a sweet, good boy. You don’t even have to try to be my good little bunny. You know that, don’t you?”

“I…I do…but…”

“No buts.” Aizawa-sensei rubbed their foreheads together, “All you need to do is let Daddy take care of you. Can you do that?”

Trembling underneath his warm, loving gaze, Izuku let out a slow breath. A rush of adulation bloomed in the center of his chest, spreading out as a wave of tingles that buzzed in the tips of his fingers and toes. Staring up into those dark eyes, Izuku nodded, enraptured and utterly, completely in love. If…if that was what his Daddy wanted then he…he could easily follow along obediently.

“Good boy. Now, come here…let me spoil you, my beautiful little bunny.”

Curling his hands around the back of Izuku’s head, Aizawa-sensei pulled him forward into a rougher, more possessive kiss. A sweet tasting tongue pushed between his lips just as Aizawa-sensei started to rapidly buck his hips again, driving his cock in deep. Squealing happily into his mouth, sucking eagerly on his tongue, Izuku clung tightly to the back of his jumpsuit. The prominent veins running along the length of Aizawa-sensei’s cock grazed along the inside of his ass, creating a friction that made stars burst across his vision. Super-heated pleasure whirled around in his crotch, spreading out through his body in massive shockwaves. A steady thrum of heat reverberated from somewhere deep inside him. Precum streamed out of his cock, dribbling along the length to soak into his pubic hair.

Good…good, good, good-! Aizawa-sensei’s cock felt so good-! He couldn’t-! He couldn’t hold on for much longer-! It felt so incredibly good-! He…he was gonna cum-! Izuku squeezed his eyes tightly closed, desperately pushing back against the immense pleasure growing stronger and stronger inside of his belly. Not yet-! Not yet-! He…he wanted to cum together with his Daddy-!

Tugging away from the kiss, Izuku panted weakly, “Wa…Wait…gonna…please-! D-Daddy-! Wai-!”

“Are you gonna cum, little bunny?” Aizawa-sensei breathed against his lips, “Is my cock gonna make you cum?”

“Yes…please…! Wa…Wait-!”

“Wait?” Aizawa-sensei chuckled, “Why? Don’t you want to cum for me, little bunny?”

“I…I do but-! But-!”

Pushing in even closer, Aizawa-sensei brought his mouth to his ear and whispered, “Then cum. Cum, my little bunny. Cum for me!”

Well, it wasn’t like he could tell his Daddy no. His fingers curled tighter into the back of his jumpsuit. Lurching forward to smash his lips against Aizawa-sensei’s, Izuku wrapped his legs around his waist as he continued to pound deep into him. Too good-! Too good-! He couldn’t-! Izuku’s eyes clenched closed then flew open, rolling back into his head. Daddy’s cock-! Daddy’s cock-! He loved Daddy’s cock-! He…he was gonna-! A ripple of tension rolled through his body. His hips strained up off the desk. Just as the pleasure was building to a crescendo, reaching the point that it could not be denied any longer, Aizawa-sensei slammed forward, completely sheathing his length inside. His cock swelled up even bigger inside, stretching him even further open. Izuku let out a high pitched squeal. He came only a few seconds before Aizawa-sensei. Thick ropes of white sprayed from the slit, splattering all over his belly. A dense, thick heat flooded into him, coating the interior walls of his ass.

Izuku violently shuddered. Immense pleasure coursed through his nerves, amplified even further by Daddy’s cum being pumped into his belly. Cumming himself was good but cumming together with Daddy…there was nothing better. He could stay like this, wrapped in his Daddy’s arms for the rest of his life and be happy. The thought of having to go back to their expected relationship of student and teacher once he left this room…it was almost too much for him to bear.

Pulling back with a soft gasp, Aizawa-sensei brushed the backs of his fingers along the curve of his cheek, smiling gently, “Did it feel good, my little bunny?”

He nodded shakily, returning his smile with one of his own, “It…it did…”

Looping his arms around Aizawa-sensei’s neck, Izuku pushed up to press a clumsy kiss to his lips, “Can…can we do it again?”

“Not here.” Aizawa-sensei sighed, “We’re already pushing our luck. But,” he continued when Izuku deflated a little from disappointment, “you’re coming back to my apartment with me tonight.”

“H-Huh? Really?!” Izuku gasped, his eyes widening. He sat up a little straight, shivering as Aizawa-sensei’s still hard cock shifted inside of him. A spark of heat radiated out from the base of his belly but he barely registered it. His heart fluttered excitedly. He…he had heard him correctly, right? He got to go home with Aizawa-sensei? He got to spend the entire night with him? That…that was what he meant, right?

A pleased smirk tugged at the corners of Aizawa-sensei’s lips. He brushed a stray lock of hair away from Izuku’s forehead, “I think it’s about time that I spend more than just an hour spoiling my little bunny. So,” his smirk grew even bigger, “you are staying with me tonight and I,” he curled his arms tightly around him, “am not going to let you go until the morning. Does that sound like something you’d want, my beautiful little bunny?”

“Yes…” Izuku breathed. A huge smile spread across his face. He pushed forward to firmly kiss Aizawa-sensei, “I want it! I want it!”

“Good. Now,” Aizawa-sensei kissed the corner of his mouth, “we’re going to get cleaned up. You’ll go get your homework done in the library. I’ll come get you when I’m done grading these tests.”

“Okay.” Izuku hesitated for a moment then asked shyly, “Can I have another kiss? A real kiss this time?”

“For you, my bunny, anything.” Aizawa-sensei rasped, leaning in close to capture his mouth in a sweet, gentle kiss that would be enough to hold him over until that night…but not by much.
