His phone chimed with a familiar ringtone just as he was sliding the book he’d spent the past twenty minutes for. Deku froze, his heart dropping into his stomach like a chunk of ice. A chill raced through him. Moving more on instinct than anything else, his hand jumped away from the book’s spine, racing down to fish his phone out of his pocket. As he was about to tap the screen to life, he paused, biting his lower lip. He didn’t have to check to know who was texting him; didn’t really need to look to know what the message either. Deku glanced at the clock on the nearby wall. 3:45 pm – his last class ended a little over forty minutes ago. If it was an average day, he would’ve been back in his dorm by now but one of his professors had assigned a paper that was due in a few days. Wanting to get a jump start on things, he had gone to the library right after class to gather up all the necessary reading materials but it had taken him a lot longer than he thought it would to find everything he needed.

Sure, he could’ve asked the librarian to help him track down all these materials but the only ones working right now were students – one of them being the jerk from math class who had made it his mission since the start of the semester to make Deku as uncomfortable and self-conscious as possible. Even though he knew it wouldn’t be good for him to hang around the library for too long, he couldn’t bring himself to ask any of the students for help. When he made that decision, he didn’t think it would take this long. He was familiar with the layout of the library after having worked here his first semester but either the books weren’t being correctly refiled or the library had completely changed their categorizing system since a couple days ago. Regardless of why everything was so out of sorts, he’d been here for entirely too long…and Katsuki had definitely noticed.

Deku’s phone dinged again. He jumped, nearly dropping his phone in alarm. The books tucked underneath his arm shifted dangerously. Forcing himself to take a deep breath, Deku turned to deposit the stack onto one of the shelves. Nervously shifting his weight from one foot to another, he hesitated for a few moments before finally tapping his phone to life. Two messages from Katsuki. Reading the latest one made his stomach churn.

‘Goddamnit, where are you, bastard? If you’re with that trust fund asshole, I’m gonna fucking kill you.’

It was the usual threats but the tone underneath them sent a cold shiver down his spine. The trust fund asshole was Shouto, an acquaintance from biology who Deku had getting close to over the last couple of weeks. It was difficult for him to make friends – spending four grueling years in high school being mercilessly bullied about his weight, his interests, anything really hadn’t been able to just shake off once he got into college. Didn’t help that there was a fair share of bullies here as well. Previous attempts to make friends here hadn’t gone very well. Up until now, Katsuki was the only one who ever wanted to be around him. Though…Deku sighed heavily, leaning back against the stack.

What even were they? Were they friends? It felt weird to label them as that, considering everything that had happened. He wasn’t an expert on friends, not having that many in the past but he got the feeling that this kind of stuff wasn’t friendship behavior. Wasn’t like he could ask anyone. Wouldn’t that be awkward: hey, my roommate, who I thought was just my friend, has become weirdly possessive and demanding, and often demands we have sex but snarls and sneers whenever I ask about our relationship – is that weird? God, he could just imagine the face Mom or Shouto would make if he were to pose that kind of question. The more he thought about it, the more anxious he became. Katsuki’s behavior was becoming worrisome. These weren’t the first texts he gotten, demanding to know where he was, who he was with. If he didn’t respond or didn’t get back to the dorms pronto, there would be hell to pay. Katsuki wouldn’t actually kill him but he didn’t hesitate to get rough whenever Deku had the audacity to not immediately respond to his demands. He still had bruises on his hips and thighs from last time. Deku sighed again, wearily pushing a hand through his hair. What were they? That question had been on his mind for weeks now. It was driving him crazy. He would just ask Katsuki but he knew he’d only get a sneering jeer as a response.

Did Katsuki like him? Or was he just a toy to him? Someone to take his frustrations out on, to use to relieve his stress? Katsuki might be a loner – only really hanging out with Deku and his own friends from high school – but he was popular. People were constantly fawning over him, despite his abrasive attitude. Katsuki had to be the only person Deku knew who could act like that and still have people throwing themselves all over him. Maybe it was because he wasn’t the only one to see through his brutish demeanor and could recognize how strong, capable, determined and intelligent he was? Though, he didn’t doubt that Katsuki being ridiculously handsome helped out a lot. His good looks drew in a lot of girls and guys. He could have anyone he wanted on campus. All he had to do was snap his fingers and the underwear would come flying off…so then why…why did he insist on doing it with him? Why was he so hell-bent on keeping him away from their classmates? Why did he care if he and Shouto became friends? It didn’t make any sense.

His phone dinged again. Before he had time to check it, it dinged once more then again, again and again. A tremor raced up Deku’s arm. His eyes widened in alarm. That…that wasn’t a good sign. Panic began to pulse in the pit of his belly. Swallowing hard against the lump raising in his throat, Deku hesitated for a few tense moments then checked the texts that just came in.

‘Do not fucking ignore me, Deku. I can see that you’re reading my fucking texts.’

‘You have five minutes to get back here.’

‘If you aren’t here by then, I’ll burn all your superhero shit.’

‘Don’t fucking test me, Deku. Get your ass back here NOW!’

A cold jolt shook his body. Frantically fumbling with his phone, Deku hurried typed back a response: ‘I’m in the library! I’m coming back now! Please calm down!’. Without waiting to see if Katsuki would respond, Deku shoved his phone back into his pocket. He briefly considered checking out the books but quickly decided against it. His luck was already being pushed to his limit. Right now was not a good time to test Katsuki’s patience. Hurrying out of the aisle, Deku was turning left, heading towards the door when he ran straight into someone. His face smooshed into a warm, muscular chest. Stumbling backwards, he lifted his head and started to stutter out an apology, only to freeze up when his gaze met a pair of bright red eyes, blazing with a seething rage. All the warmth in his body vanished, leaving him trembling with panicky cold. H-How was he here?! Shouldn’t he be back in the dorms?!

Deku mutely opened and closed his mouth a couple times before he was finally able to squeak out “Katsuki, wha-!”

“Come with me.” Katsuki ground out through clenched teeth. Grabbing Deku’s arm in a painfully tight hold, Katsuki dragged him towards the back of the library, away from the sitting areas and aisles with the more often checked out books. Once they were at the very back, where all the dusty reference books were still perfectly lined up on the shelf, not a sign of anyone having touched them in years, Katsuki shoved him down on the rows. Deku was starting to protest, his heart hammering hard against his ribs, when Katsuki pushed him up against the stack. Clamping onto Deku’s jaw, he yanked his head back and lunged down to smash their mouths together in a rough, possessive kiss. A hot tongue, tasting vaguely of coffee and cigarettes, shoved its way into his mouth, spreading the distinct flavor of Katsuki everywhere. Warm, smooth lips moved firmly, confidently over his own, devouring him with a ferocity that made his head spin with a mixture of shameful excitement and squealing terror. They…they were still in the library! They shouldn’t be doing this here!

Even though he knew it wouldn’t do any good, Deku still slammed his hands against Katsuki’s beefy chest. The blow, as usual, didn’t even seem to register. What little strength he had was nothing in comparison to Katsuki’s. Growling low in his throat, Katsuki dropped one muscular arm to wrap it firmly around Deku’s waist. He pulled him in close, pressing them flush together. One large hand dropped even further to fondle his ass, squeezing the plump, heavy cheek with enough force to make it feel like he was trying to rip the fabric to shreds. He shoved a powerful thigh between Deku’s trembling legs, pressing up hard against his crotch. A bolt of tingling pleasure radiated up his spine. His cock immediately responded, beginning to twitch and harden. Squealing into Katsuki’s mouth, Deku jerked back, successfully breaking away from the kiss.

“Kat-! Stop-! Don’t-!” Deku panted out, trembling violently. He could barely hold himself upright. His knees had gone all watery. Icy fear thundered through his veins, turning his entire body frigid. Panting heavily, clawing and pushing at Katsuki’s cheek, Deku wrenched his head away when he tried to capture his mouth in another kiss. He…he didn’t want to do this here! No, scratch that – he didn’t want to do this at all! Being fucked like this in their dorm was bad enough but in public where anyone could see them?! He…he was already relentlessly teased. He didn’t want to add getting sexually harassed by one of the most popular guys in school to that! Tears burned at the corner of his eyes, leaking out to leave scorching trails down his cheeks. Each rapid beat of his heart sent an echo that pulsed through his arms and legs.

“Shut up.” Katsuki rasped, bending down to drag his tongue along the curve of Deku’s round cheek, licking up the tear that’d just fallen. Cruelly squeezing his ass, his broad fingers slipping between the plump cheeks to rub against him through the thick material of his jeans, he pushed his thigh harder to Deku’s crotch. He started to rock his leg back and forth slightly, grinding his beefy thigh against him. The pleasure pulsing in the base of his belly grew even stronger. Within a couple of ruts, he was rock hard, his cock straining against the front of his underwear. Flushing with violent, embarrassed heat, Deku whimpered. He hated this…he hated it! Why…why did it have to feel this good?! The corners of Katsuki’s lips tilted up into a mocking sneer, “Did you think you could hide from me? Huh?”

“I-I wasn’t-!” Deku frantically whispered, his eyes wildly darting around, looking for any hint of movement around them. Someone was going to see them! Someone was going to see and he was going to get expelled! “Professor Aizawa assigned a paper! I was getting books!”

“Getting books.” Katsuki sneered mockingly, hovering menacingly over him. If there was one thing Katsuki knew how to do well, it was using his immense, hulking size to intimidate him, “Sure you weren’t waiting for your new friend?”

“Wha-? What does Shouto have to-?!”

“Don’t-!” Katsuki snarled, “Fucking say his name in front of me! Is that who you were waiting for, huh? You’d find another guy to fawn all over you, Deku? One dick not enough for you, bastard?!”

“What are you talking about?!” Deku gasped, shrinking backwards. He…he had never seen Katsuki this angry before. His knees started to buckle. No matter how much air he pulled into his lungs, it still felt like he couldn’t get enough oxygen. Sobs began to bubble up his throat. Fresh tears cascaded down his cheeks, dribbling off his double chin. He just wanted this to stop! He wanted to go back to being friends with Katsuki, not this weird, terrifying thing that was happening! “Katsuki, please! Stop! Stop!”

Leaning back, his muscular chest heaving with shallow breaths, Katsuki stared at him silently for a moment then muttered, “You’d better not had let him see your crying face. That’s reserved,” Katsuki curled his broad fingers around Deku’s soft jaw once more, leaning down slowly to bring their faces close, “solely for me. You hear me, Deku?”

“Katsuki, pleas-!”

“Shut up.” Katsuki breathed, brushing a surprisingly sweet kiss against the corner of Deku’s lips, “And let me fuck you.”

“No-! Don’t-!” Deku started to cry out, only for his words to be cut off by a sharp gasp when Katsuki dropped his leg, grabbed hold of his hips and spun him around. A large hand landed hard in the center of his back, keeping him firmly pressed to the stacks. With his other hand, Katsuki snaked a hand around, tearing open the front of Deku’s jeans. He grabbed his pants by the seat and wrenched them down, exposing his plump, round butt. Sobbing miserably, Deku clamped his chubby hands over his mouth, desperate to remain as quietly as possible. There came the sound of Katsuki spitting into the palm of his hand, followed almost immediately by the sensation of his large, wet digits pressing to his twitching hole. A shudder raced through Deku’s body. He bit his tongue to hold back a cry. With no semblance of gentleness – not that he was expecting any by now – Katsuki roughly prepped him, stretching him open in preparation for something much bigger than his fingers.

“We’re in public-!” Deku gasped weakly, trying very hard to ignore how good it felt to have Katsuki’s calloused fingers rapidly thrusting into him, “Please-! Please stop-! Let’s go back to the dorm!”

“I said,” Katsuki snarled, reaching around him to eagerly palm across his chubby belly, pressing his fingers sinking into the rounded curve, “shut up!”

Katsuki’s fingers slipped out of his hole. The muscles in his lower back tensed up in anticipation of what was coming next. Straightening up, still hungrily stroking his soft chest, his stomach and quaking thighs, Katsuki lead the head of his cock to Deku’s entrance. The tip pressed insistently to the sensitive skin, sending out a wave of tingling. In response, Deku clamped his hands down tighter over his mouth. Scalding tears slid down his burning hot cheeks. His shoulders bounced from the force of his sobs. There was no point in begging but he could still feel the pleads bubbling up his throat. Why…why was Katsuki doing this to him? Did he actually hate him and acting like they were friends had all been some kind of joke? Deku’s heart clenched painfully at the thought. He…he couldn’t stand much more of this. It hurt…it fucking hurt so much.

Lowering his hands just slightly from his mouth, Deku whispered in a strained voice, “Why…why are you doing this to me? I-I thought we were friends!”

There was a brief pause then Katsuki snorted mockingly into his ear. Deku tensed up, his blood running cold then, to his surprise, Katsuki rested his chin on the top of his head. He lightly stroked the tips of his fingers along the pronounced curve of Deku’s belly. Eyes stretched open wide, his mouth hanging open slightly, Deku found himself leaning back into Katsuki’s warmth before he could catch himself. This…this was something Katsuki used to do all the time. He was so much bigger than him, he could easily use his head as a headrest. The first time he had done it…fuck, Deku could remember being so happy, so comfortable and delighted. Why had all that changed? Why was Katsuki-?

“Why won’t you get out of my head?” Katsuki asked in a low, husky voice.

Deku tensed up, his eyes widening even further. What…what was that supposed to mean? Get out of his head?

Exhaling slowly, Katsuki slid down to bring his mouth close to Deku’s ear, “I’ve tried to get you out for weeks but you’re all I can ever think of. It’s driving me crazy. Every day, every moment, I’m thinking of you – what are you doing? Who are you with? Has someone else finally realized how adorable you are and is trying to take you away from me? I can’t stop thinking about you. It pisses me off, Deku. How much I want to touch you, how much I want for you to be with me, how much I can’t stand you being away from me.”

Katsuki nipped hard at his earlobe, wrenching a startled gasp out of him, “I don’t get it either but…I’m not gonna let you go.”

Without any warning, Katsuki rammed his hips forward, forcing the entirety of his length deep inside Deku’s tight, twitching hole. An immense shriek of pleasure wailed up from his butt, coursing throughout the rest of his body in a golden wave. He would’ve been screaming at the top of his lungs if Katsuki didn’t clamp one large hand over his mouth, muffling the sound. Katsuki didn’t give him any time to adjust to the sudden monstrously large intrusion. Holding tight to Deku’s hips with his other hand, he held him in place as he brutally slammed into him. Wailing into Katsuki’s palm, Deku reached back to claw frantically at his significantly larger body. Too much-! It was too much-! He didn’t like it this deep! This rough! He…he could feel Katsuki’s dick in his belly! His insides were being assaulted by his intense, burning heat! Prominent veins scraped along the interior of his butt.

Good…it felt so good-! Being fucked so hard by Katsuki’s penis felt so good-! He hated it-! He hated it-! He didn’t want this-! He didn’t want to cum! He didn’t understand any of this-! Why…why if this annoyed Katsuki so much, then why was he doing this?! Why?!

“Stop-!” Deku choked out, the sound muffled to nearly being incoherent, “Stop! Pleash-! Pleash-!”

Panting harshly, Katsuki bit his ear again, “Shut up! Stop fucking lying to me! Your slutty hole is clamping down so tightly around me, it’s making it hard to move. Every time I pull out, you suck me back in. Don’t lie. Don’t fucking lie! You love this…you love me! You want me!”

“I-!”

“And I…I…” Katsuki faltered, his breath catching. He curled his arms tight around Deku’s trembling form, crushing them together. Brushing a kiss against the line of his throat, Katsuki panted, “I’m not gonna let anyone take you from me. You’re mine…you’re mine!”

Jerking back, sliding his cock out of Deku’s hole, Katsuki roughly turned him around, slamming him up against the stacks. Sliding his hands up underneath Deku’s trembling legs, he wrenched them up, easily lifting him up off the floor. Despite his weight (which would’ve made it difficult for a lot of people to hold him up), Katsuki held him in place effortlessly as he brought the head of his thick, fat cock to his entrance and slammed into him. His hole spread open eagerly, swallowing up Katsuki’s penis. Deku bit down hard on his lower lip to hold back a shrieking cry. Precum dribbled out of his cock, splattering all over his exposed belly. He grabbed hold of his shoulders to give himself more leverage. In this new position, he could clearly see Katsuki’s flushed, sweaty face. Bright red eyes, blazing with hazy lust and hungry desire, watched him closely, devouring every gasp, every tear, every sob. Flinching away in embarrassment, more terrified now than ever that they were going to be caught, Deku wanted nothing more than to hide his face.

He hated this…he hated how Katsuki was treating him but hated how much he was enjoying it even more. Cumming…he was gonna cum-! He was gonna cum while being assaulted in a pubic library by someone he thought was his friend! Izuku sobbed miserably, turning his head even further away. Exhaling shakily, Katsuki leaned down to lick up another tear.

“Cute…” He gasped, the rhythm of his thrusts becoming erratic. His cock grew even bigger inside him, stretching him open further, “You’re so cute…cry…cry even more for me, Deku.”

“Stop-! Don’t-! Don’t wanna cum-! Please-! Pleash-!”

Giggling low in his throat, Katsuki sweetly kissed him, “Cum…cum! Cum with me buried deep inside you! Cum…Deku…my Deku, my adorable, chubby Deku…cum! Cum! Cum!!”

As much as he wanted to resist, when Katsuki ordered him like that…he couldn’t. Tensing up, a harsh breath rippling out of his seizing chest, Deku’s hips strained forward as he came, spraying thick ropes of cum all over his and Katsuki’s stomachs. Immense waves of golden pleasure crashed through him, momentarily knocking his sense out of the way, leaving him floating on a surf of ecstasy. Just as he was slowly coming down from his orgasm, Katsuki lunged down, biting hard onto his shoulder. He viciously slammed his hips forward, sheathing the entirety of his cock inside him. His cock pulsed against the spasming interior of his ass then a scalding gush of cum was pouring into him, coating his insides. Deku shuddered, clenching his eyes tightly shut. Warmth spread through his belly. Good…it felt so good…Deku sobbed softly.

Carefully dragging his tongue across the fresh bite mark, Katsuki murmured, “You’re mine. No matter how much you struggle or scream or cry, I’m never gonna let you go. Got that,” he leaned back to glare down at Deku with a piercing gaze, “Deku?”

Deku stared silently up at him for a moment, swallowed hard against the dryness in his throat and shakily nodded. He…he didn’t get any of this. Scared…he was scared but there was no standing against Katsuki, was there?
