Chapter 3: Rising Action
Shoto couldn't find Katsuki anywhere.
He had checked the training grounds, the cafeteria, even the dormitory showers. His Quirk hummed restlessly beneath his skin, that strange sixth sense that always told him when something was wrong.
The library was his last resort.
The moment he pushed open the heavy wooden doors, the scent of old paper and leather bindings wrapped around him like a familiar embrace. The hushed whispers of students bent over their textbooks filled the air, but Shoto's attention was drawn immediately to the far corner, where a single figure lay sprawled across one of the study tables.
Katsuki.
Shoto came closer, and find out Katsuki was sleeping, his head resting on opened notebook.
His spiky blonde hair was slightly disheveled, his red eyes closed in peaceful slumber. The faint sound of his steady breathing filled the quiet library, a stark contrast to the usual tension that radiated from him. Shoto couldn't help but smile at the sight—Katsuki, the self-proclaimed "Dynamite," reduced to a peaceful pile of muscle and exhaustion.
Shoto reached out, gently brushing a stray lock of hair from Katsuki’s forehead. The blonde’s eyelids fluttered slightly, but he didn’t wake. His lips parted in a soft exhale, his chest rising and falling in a slow rhythm.
Shoto understand they weren't alone here, but in Katsuki's corner they were invisible for few students, studying throughout three or four book shelves from they.
Shoto wants it so bed. He gently kissed Katsuki's forehead.
"You need to stop sleeping in the library," Shoto murmured, his voice barely above a whisper. "You'll get kicked out eventually."
Katsuki's eyes fluttered open, red irises blurry with sleep. For a moment, he just stared at Shoto, his expression unreadable. Then a slow, lazy smirk spread across his face.
"Shoto," he rumbled, voice still thick with sleep. "You found me."
Shoto chuckled, shaking his head. "You're impossible. Come on, let's get you to bed before you fall asleep on top of someone's research paper."
Katsuki stretched, his muscles flexing under his tight uniform.
"I'm totally satisfied with this place for sleeping" Katsuki yawn, then looks in Shoto's eyes and asked, teasingly:"In my bed we usually do funnier things then sleeping. So you was looking for me...for that thing?".
Katsuki's smirk deepened, his red eyes flickering with mischief as he watched Shoto's reaction. The library was quiet, the air thick with the scent of old books and the faint hum of distant conversations. But in this corner, it was just the two of them, wrapped in a bubble of tension that crackled like static.
Shoto's fingers twitched at his sides, his jaw tightening slightly. He could feel the heat rising in his cheeks, the way his pulse quickened at the suggestion. Katsuki had always been bold, but there was something different about him today—something softer, more vulnerable beneath the bravado.
"Maybe I was," Shoto admitted, his voice low. "And yes, in your bedroom it is more convenient to have sex. We can move there...".
"Don't you scared, Half and Half?" Katsuki laughed. Now he was fully awake, and ready to having fun.
Shoto blushed. He has never thought he would ever have sex in library.
"I... It's just...tense" Shoto managed to say.
"Come on, Hot guy, I know you really want to claim me on this table" Katsuki grinned, and wrapped his hands around Shoto's neck, their faces moving closer to each other.
Katsuki was waiting for Shoto's move.
He knew Shoto wouldn't refuse. And Shoto didn't disappointed Katsuki. Shoto kissed Katsuki's lips, finally allowing himself to dive in deep desire, keeping in mind they in public space.
His hands slid up Katsuki's back, feeling the hard muscles beneath his uniform. The blonde's body responded immediately, pressing closer, his fingers tangling in Shoto's hair.
"You're impossible," Shoto murmured against Katsuki's lips, his voice rough with need. "But I can't resist you."
Katsuki smirked, his red eyes burning with intensity. "Good. Because I wasn't planning on letting you."
Shoto's hands slid down to grip Katsuki's hips, pulling him closer. The blonde's body was warm, his muscles tense with anticipation. Shoto could feel the heat radiating off him, the way his breath hitched as their bodies pressed together.
Shoto quickly, and without visible problems, moved Katsuki on table and pushed him a little bit on it, keep kissing Katsuki. Their hands working hard.
Shoto's fingers trembled as he fumbled with Katsuki's belt, the leather slipping from his grasp. The blonde smirked against his lips, his own hands more confident as they tugged at Shoto's uniform, the fabric straining against his shoulders.
"Someone's eager," Katsuki murmured, his voice rough with amusement. His fingers traced the line of Shoto's jaw, tilting his head back to deepen the kiss. The library around them was a blur of muted colors and distant whispers, but all Shoto could focus on was the heat of Katsuki's body against his, the way his fingers dug into his hips, pulling him closer.
Shoto pulled Katsuki's pants down with underwear at once, releasing Katsuki's hard dick. But Shoto was interested in other Katsuki's part. He grabbed both Katsuki's legs and spreaded them apart, placing them on his shoulders.
Shoto, feeling urge to tease Katsuki, grabbed Katsuki's dick and with his quirk made narror freezing path along Katsuki's length.
Katsuki's breath hitched, his back arching off the table as the cold seared through him. His fingers clawed at the wood beneath him, his cock twitching in Shoto's grip despite the icy shock. Katsuki gasped, his voice rough with surprise. His red eyes burned with a mix of irritation and arousal, his body trembling as Shoto's Quirk traced a delicate line of frost along his shaft. The contrast of the cold against his heated skin sent a shiver down his spine, his muscles tensing beneath Shoto's touch.
Shoto smirked, his turquoise eye gleaming with mischief as he watched Katsuki's reaction.
Other Shoto's hand found Katsuki's ass hole. Finger entered Katsuki, immediately sending inside heat, as Shoto used his fire quirk.
Katsuki’s body arched violently, his fingers clawing at the table as the sudden shift from ice to fire overwhelmed his senses. His cock throbbed painfully in Shoto’s other hand, pre-cum already leaking in steady drops onto his stomach. Katsuki gasped, his voice rough with shock. His red eyes burned with a mix of frustration and desire as he glared up at Shoto. "You’re gonna pay for that, Half and Half."
Shoto smirked, his fingers curling slightly inside Katsuki, making the blonde’s breath hitch. "You love it," he murmured, his voice low and teasing.
"You fucking tease! Can your dick hitting both fire and ice at the same time too?" Katsuki moaned, he sounds bratty, but Shoto knows Katsuki so well, and he understands that Katsuki loves it.
Shoto's fingers moved inside Katsuki, slowly, teasingly, feeling the tight heat around them. He leaned down, pressing his lips to Katsuki's inner thigh, his breath hot against the blonde's skin.
"Now I'll show you what I can do with my Quirk," Shoto murmured, his voice low and dark with promise. His fingers slid out of Katsuki, leaving him feeling empty and aching. The blonde whined softly, his hips lifting off the table in a silent plea.
Shoto smirked, his turquoise eye gleaming with mischief. He reached into his pocket and pulled out a small, sleek bottle of lube.
The sound of the cap unscrewing was almost obscenely loud in the quiet library, but neither of them cared. Katsuki’s breath hitched as Shoto’s fingers returned, slick and warm, pressing against him again. The blonde’s hips lifted instinctively, seeking more, his fingers curling into the edge of the table.
“Fuck, Shoto—” Katsuki gasped, his voice rough with need. The sensation of Shoto’s fingers inside him, moving with deliberate slowness, was almost too much. The contrast of the cold air against his heated skin made every touch feel electric.
Already three fingers inside Katsuki stretching him. Each finger was different - one extremely cold, second - very hot. Third was cood too.
"You asked about my dick..." Shoto whispered on Katsuki's ear.
"I'm not just going to show you what my Quirk can do. I'm going to show you what *I* can do."
Katsuki's breath hitched as Shoto's fingers curled inside him, the alternating heat and cold making his vision blur with pleasure. The blonde's fingers dug into the table, his hips lifting to meet Shoto's touch. "You're such a fucking tease," he growled, but there was no real bite to his words.
Shoto smirked, his turquoise eye gleaming with mischief as he watched Katsuki squirm.
Shoto withdrew fingers. He didn't plan to use condom.
He wanted to feel Katsuki raw.
Shoto's fingers slid out of Katsuki with a wet sound, leaving the blonde gasping and empty. The air between them crackled with tension as Shoto unzipped his pants, his cock springing free—thick, flushed, and already glistening with pre-cum. Katsuki's red eyes locked onto it, his breath hitching as Shoto gripped himself, stroking slowly.
Shoto slowly attached his dick to Katsuki's entrance. Katsuki felt something, but then Shoto in one push entered Katsuki on full length. Katsuki was right: Shoto controlled his quirk on his dick completely, he could change temperature of different parts of dick. Freezing cold tip hits Katsuki's prostate immediately.
The blonde's back arched violently, his fingers clawing at the table as an involuntary cry tore from his throat. His cock twitched painfully, pre-cum dripping in thick ropes onto his stomach. The sensation was unlike anything he'd ever felt - an icy burn that made his entire body shudder. Shoto—!" Katsuki gasped, his voice breaking. His muscles clenched instinctively around Shoto's cock, trying to resist the overwhelming sensation.
Shoto smirked, watching Katsuki's reaction with dark satisfaction. He pulled out slightly, then thrust back in with deliberate slowness, this time using his fire quirk on the head of his cock.
Katsuki didn't notice when he grabbed Shoto's back, pulling him closer, and now his nails scratching Shoto skin on back, leaving deep marks.
Katsuki's red eyes were wide, his breath coming in ragged gasps as Shoto's cock moved inside him. The alternating sensations—first the icy cold, then the searing heat—were overwhelming, each thrust sending jolts of pleasure-pain through his body. Katsuki's voice cracked, his fingers digging into Shoto's shoulders. The blonde's body trembled, his cock throbbing painfully between them, leaking steadily. He could feel every inch of Shoto's length, the way it stretched him, filled him completely.
Suddenly, after freezing cold, Shoto entered on full length again, and his dick begins to heating up. It becomes hotter and hotter inside.
Katsuki's body trembled violently as Shoto's cock pulsed with searing heat, the contrast to the previous icy cold making his vision blur. His fingers clawed at Shoto's back, nails digging deep enough to draw blood, but the pain only sharpened the pleasure. "F-Fuck! Katsuki gasped, his voice breaking as the heat radiated through him. His cock twitched violently, pre-cum dripping steadily onto his stomach. "You're taking it so well," he murmured, his voice low and rough. His hands gripped Katsuki's hips firmly, pulling him closer with each thrust.
It was too much to Katsuki. He came fantastically.
His orgasm ripped through him like a wildfire, his body convulsing as thick ropes of cum painted his stomach and chest. Katsuki's breath came in ragged gasps, his fingers clawing at Shoto's back as wave after wave of pleasure crashed over him. His cock pulsed violently between them, the sensation of Shoto's Quirk still sending jolts of pleasure-pain through his body.
Shoto watched Katsuki come undone beneath him, his own breath coming in sharp gasps. The sight of the blonde falling apart, his muscles trembling and his voice breaking, was intoxicating.
"Little Katsuki, came after my special technique, called "fire sword", ha?" Shoto laughed, softly kissing Katsuki's cheek.
But Shoto wasn't done, and continue moving, chasing his own release.
His thrusts became erratic, his grip on Katsuki's hips tightening as he chased the edge of his own climax. The library around them faded into a blur of muted colors and distant whispers, but all Shoto could focus on was the heat of Katsuki's body, the way his muscles clenched around him, the way his breath came in ragged gasps.
It didn't take too much time. Shoto came, and in this moment Katsuki understand, why Shoto didn't wear the condom: Shoto came, and his seed hits Katsuki's ass. First jet was extremely cold. Next - boiling hot. In addition, Shoto could control the temperature of his seed , which was now burning inside Katsuki like a wildfire.
Katsuki’s entire body convulsed, his back arching off the table as Shoto’s release sent waves of pleasure-pain crashing through him. His fingers clawed at Shoto’s shoulders, nails digging into flesh as his vision blurred with overwhelming sensation. The alternating extremes—first the icy cold, then the searing heat—were too much. His cock twitched violently, thick ropes of cum spilling onto his stomach in hot, sticky spurts.
"F-Fuck—!" Katsuki gasped, his voice breaking as his body trembled uncontrollably. He came second time, just feeling Shoto's seed inside him.
His body was trembling, his muscles clenched around Shoto's cock, trying to milk every last drop from him. The sensation of Shoto's cum—first freezing cold, then scorching hot—was unlike anything Katsuki had ever experienced. He could feel it spreading inside him, filling him completely, the heat radiating outward in waves that made his toes curl.
Shoto collapsed forward, his forehead resting against Katsuki's shoulder as he caught his breath. His hands still gripped Katsuki's hips, fingers digging into the muscle as the last aftershocks of his orgasm rippled through him. The library around them was still quiet, the distant murmur of students studying a world away from the intensity of what had just happened.
"You bastard! Looks totally satisfied with life, ha?" Katsuki said.
His voice was rough, his body still trembling from the aftermath. His fingers curled into Shoto’s shoulders, nails digging into the fabric of his uniform. The blonde’s red eyes were half-lidded, his breath coming in uneven gasps as he tried to recover from the overwhelming pleasure.
Shoto chuckled softly, his lips brushing against Katsuki’s ear. "You’re the one who looks like you’ve been thoroughly claimed," he murmured, his voice low and teasing. His fingers traced lazy circles on Katsuki’s hip, feeling the way the blonde’s muscles still twitched beneath his touch.
Katsuki let out a weak groan, his body still trembling.
"I told you... You'll pay for this!" Katsuki closed the eyes, breathing.
His body was still burning from Shoto's "fire sword" technique, but he didn't want to admit how good it felt. He could feel Shoto's cum inside him, still shifting between freezing cold and scorching heat, making his muscles clench involuntarily.
The library was still quiet around them, the distant murmur of students studying nothing more than background noise. Katsuki could hear the faint rustle of pages turning, the occasional cough, but none of it mattered. All that existed in this moment was the warmth of Shoto’s body pressed against his, the way his breath fanned across Katsuki’s skin, the lingering ache between his thighs.
Katsuki opened his eyes and looked at Shoto.
"You woke up a beast, Half and Half!" Katsuki guided Shoto's hand to Katsuki's dick. It was hard again!
Katsuki smirked, his fingers tightening around Shoto’s wrist. The blonde’s red eyes gleamed with challenge as he met Shoto’s gaze, his voice a low, teasing rumble. "Looks like you didn’t wear me out enough, Hot Guy."
Shoto’s fingers flexed instinctively, his grip tightening around Katsuki’s length. The blonde’s cock was already hard again, hot and heavy in his palm, pre-cum glistening at the tip. Shoto’s breath hitched, his turquoise eye flickering with heat as he watched Katsuki’s reaction.
"Looks like it's your turn to show me your special technique, Katsuki" Shoto laughed.
"Exactly" Katsuki reply, turning Shoto over on his stomach, spreading Shoto's buttocks.
His fingers traced the curve of Shoto's ass, feeling the way the muscles tensed beneath his touch. The library around them had faded into a distant hum, the scent of old books and leather bindings replaced by the musky aroma of sex and sweat.
"Let's see how you handle my 'explosive' technique," Katsuki murmured, his voice rough with anticipation. He leaned down, pressing his lips to the back of Shoto's neck, his breath hot against the skin. His fingers teased at Shoto's entrance, little sparks of his Quirk already making Shoto shiver.
Shoto let out a low groan, his fingers clutching at the edge of the table.
Katsuki didn't prepared Shoto, he just entered his ass hole in one thrust.
Shoto's back arched violently as Katsuki's thick cock stretched him open, the sudden invasion making his breath catch in his throat. His fingers clawed at the table, the wood groaning under the pressure. "F-Fuck!" Shoto gasped, his voice breaking as Katsuki bottomed out inside him.
The blonde smirked, watching Shoto's reaction with dark satisfaction. His red eyes gleamed with mischief as he leaned down, pressing his lips to Shoto's ear. "You think you're the only one who can play rough, Half and Half?" he murmured, his voice rough with amusement. His hands gripped Shoto's hips firmly, pulling him closer as he began to move.
Katsuki thrusting quickly, his hands making small sparks, which stabbing Shoto's hips, making him moaning. Shoto's body trembled beneath him, his fingers clawing at the table as Katsuki's cock moved inside him. The blonde's fingers dug into Shoto's hips, pulling him closer with each thrust, his breath hot against Shoto's neck. The library around them was a blur of muted colors and distant whispers, but all Shoto could focus on was the heat of Katsuki's body, the way his muscles tensed beneath his touch, the way his breath came in ragged gasps.
"You're taking it so well," Katsuki murmured, his voice low and rough. His hands gripped Shoto's hips firmly, pulling him closer with each thrust.
"Your hands could only make this, Great Dynamite?" Shoto teasing.
"I expected more from the legendary Dynamight," he panted, his voice strained but laced with challenge. "You're holding back."
Katsuki's smirk deepened, his red eyes flickering with amusement. "Oh, you want more fireworks, Half and Half?" His fingers curled into Shoto's hips, his Quirk already humming beneath his skin. "Fine. Let's see how you handle the real deal."
With a sudden burst of speed, Katsuki's thrusts intensified—sharp, precise, each one sending sparks dancing across Shoto's skin. The blonde's hips snapped forward with brutal efficiency, his cock driving deep inside Shoto with every movement.
"You need to improve your skills, I thought you can use your quirk on dick, like me" Shoto moaned.
His voice was breathy, his fingers clawing at the table as Katsuki's relentless thrusts sent waves of pleasure-pain through his body. The library around them had dissolved into a blur, the distant hum of students studying nothing more than background noise to the raw intensity between them.
Katsuki let out a low, dark chuckle, his breath hot against Shoto's ear. "You think I'd let you show me up, Half and Half?" His fingers tightened on Shoto's hips, his Quirk sparking violently beneath his skin. "Watch this."
With a sudden, sharp movement, Katsuki pulled out completely, leaving Shoto gasping and empty.
The blonde's smirk was wicked as he grabbed Shoto by the hips and flipped him onto his back, his red eyes burning with intensity. "You want fireworks? I'll give you a fucking supernova."
Before Shoto could react, Katsuki's Quirk flared to life. Electric sparks crackled around his cock as he gripped himself, his fingers leaving faint burns on his own skin. Shoto's breath hitched as he watched, his body still trembling from the sudden emptiness.
"You're insane," Shoto whispered, his voice rough with arousal.
Katsuki grinned, his teeth flashing white in the dim library light.
"That’s the point, Half and Half." His fingers tightened around his cock, sparks dancing along his skin, and he lined himself up against Shoto’s entrance again. This time, he didn’t tease. He thrust in with a single, brutal motion, his Quirk flaring as he did.
The sensation was unlike anything Shoto had ever felt. The initial stretch was sharp, almost painful, but then—fire. Not just heat, but *electricity*, crackling along every nerve as Katsuki’s cock pulsed inside him. Shoto’s back arched off the table, his fingers clawing at the wood beneath him.
Now Katsuki have no need to use hands. With every thrust, sparks from his dick make little explodings inside Shoto's ass, hitting Shoto's prostate.
Shoto's body trembled violently, his fingers clawing at the table as Katsuki's cock moved inside him.
"Fuuuuck!" Shoto moans. Katsuki's technique feels amazing.
Each thrust sends a surge of electricity through Shoto's body, making his toes curl and his back arch. The sparks from Katsuki's Quirk are like tiny explosions inside him, each one hitting his prostate with precision.
Shoto's fingers dig into the table, his knuckles turning white as he tries to anchor himself to something solid. The library around them is a distant blur, the scent of old books and leather bindings replaced by the musky aroma of sweat and sex. He can feel Katsuki's breath hot against his neck, the blonde's muscles flexing with each powerful thrust.
"You're taking it so well," Katsuki growls, his voice rough with desire.
"My seed will explode your ass, Hot guy!".
Katsuki's voice is a low, growling purr against Shoto's ear, his breath hot and uneven. His hips snap forward again, and this time, the sparks from his Quirk flare brighter, more intense. Shoto can feel them dancing along his nerves, each tiny explosion sending a wave of pleasure-pain through his body.
Shoto's body arches off the table, his fingers clawing at the wood beneath him. "K-Katsuki—!" he gasps, his voice breaking as the sensation becomes too much. His cock throbs painfully, pre-cum dripping in steady streams onto his stomach.
"Fuck! Can't last any longer!" Katsuki groaned, as he came inside.
His cock pulsed violently, thick ropes of cum spilling into Shoto's ass. The blonde's muscles clenched around him, milking every last drop as Katsuki's Quirk sent sparks dancing across his skin. His breath came in ragged gasps, his fingers digging into Shoto's hips as he rode out the aftershocks of his orgasm.
Shoto's body trembled beneath him, his own release still building. The sensation of Katsuki's cum inside him—hot and electric—sent waves of pleasure crashing through him. His cock twitched painfully, pre-cum dripping onto his stomach in steady streams. Katsuki grabbed Shoto's dick, and let sparks dance on Shoto's skinn. The sensation was electric, sending jolts of pleasure through Shoto's body. His breath hitched as Katsuki's fingers traced patterns of fire and ice along his length, the contrast of temperatures making his vision blur. The blonde's smirk was wicked as he watched Shoto's reaction, his red eyes gleaming with satisfaction.
"You're gonna come so hard for me, Half and Half," Katsuki murmured, his voice rough with amusement. His fingers tightened around Shoto's cock, his Quirk sending sparks dancing along the shaft. The sensation was overwhelming, each tiny explosion sending waves of pleasure-pain through Shoto's body.
And Shoto did. He came so hard.
His body arched violently off the table, his fingers clawing at the wood as thick ropes of cum painted his stomach. The sensation of Katsuki's sparks dancing along his cock, combined with the aftershocks of his own orgasm, sent him spiraling into a dizzying high. His breath came in ragged gasps, his body trembling uncontrollably as wave after wave of pleasure crashed over him.
Katsuki watched with a satisfied smirk as Shoto came undone beneath him, his red eyes dark with lust. The blonde leaned down, pressing his lips to Shoto's collarbone, feeling the way his body still trembled with aftershocks.
His fingers traced lazy patterns on Shoto's hip, his touch surprisingly gentle after the intensity of what they'd just shared. The library around them was still quiet, the distant murmur of students studying nothing more than background noise to the intimacy between them.
"Fuck... you're gonna kill me one day," Shoto panted, his voice rough with exhaustion. His fingers curled into Katsuki's hair, pulling him closer for a slow, deep kiss. The taste of sweat and desire lingered between them, a reminder of the raw passion they'd just unleashed.
Katsuki smirked against his lips, his red eyes gleaming with satisfaction.
"It's you who found me here, in library, and wanted me so hard!" Katsuki answered, and kissed Shoto too.
"You're the one who started this, Half and Half. Don't act like you didn't enjoy every second of it."
Shoto let out a breathless laugh, his fingers tracing the curve of Katsuki's jaw. The blonde's skin was still flushed, his red eyes half-lidded with satisfaction. The library around them was a blur of muted colors and distant whispers, but all Shoto could focus on was the warmth of Katsuki's body against his, the way his fingers traced lazy patterns on his hip.
"You're impossible," Shoto murmured, pressing another kiss to Katsuki's lips. "I didn't hurt you with my "fire sword ""?.
His voice was soft, but there was a playful edge to it, as if he already knew the answer.
Katsuki smirked, his fingers tracing idle circles on Shoto’s hip. "Your fire sword just burned me inside, but your semen quickly pit up the fire" Katsuki grinned.
"And I loved it" he added.
The library was silent around them, the air thick with the scent of sex and sweat. Shoto's fingers traced lazy patterns on Katsuki's back, feeling the raised marks his nails had left earlier. His body hummed with the afterglow, his muscles twitching occasionally as the last remnants of pleasure pulsed through him.
Shoto chuckled softly, his turquoise eye gleaming with amusement. "You're impossible," he murmured, pressing a gentle kiss to Katsuki's forehead.
