Chapter 2: Building Tension
Izuku was late on training. "Where are this stupid nerd again?" Katsuki thought, making his way to Izuku's bedroom.
He was still in his training clothes, the sweat from his workout still drying on his skin. The door was slightly ajar, and he could hear the faint sound of Izuku's voice from inside.
He pushed the door open and stepped inside, his eyes immediately drawn to the sight of Izuku sprawled across the bed. The younger hero was lying on his stomach, his back muscles flexing as he moved his hips in slow, deliberate motions. His skin was flushed from exertion, and a sheen of sweat glistened on his freckled shoulders.
Izuku glanced over his shoulder at the sound of the door opening, his green eyes meeting Katsuki's with a mix of surprise and amusement.
"Kacchan? What are you doing here?" he asked, his voice slightly breathless from his earlier exertions. He pushed himself up onto his elbows, the muscles in his arms flexing as he did so.
Katsuki leaned against the doorframe, his arms crossed over his chest. His spiky blonde hair was slightly damp with sweat, and his red eyes were sharp with curiosity. "I could ask you the same thing," he replied, his voice gruff but carrying a hint of teasing. "You're supposed to be at the training facility, not lounging around in your room."
Izuku sat up fully, swinging his legs over the edge of the bed. Katsuki finally could see what Izuku exactly did - Izuku's hand tightly grabbing flashlight (artificial vagina). Izuku's dick was still inside, looks like Katsuki came across Izuku in the middle of jerking off.
"What is it, nerd? Your hand is already not enough?" Katsuki went closer, closing the door behind himself.
His eyes never left Izuku's hand - the way his fingers were wrapped around the flashlight, the way his knuckles were white from gripping it so tightly. The sight sent a jolt of heat straight through him.
"Never see this, ha?" Izuku laughed, slowly withdrew his dick from artificial vagina. Both dick and flashlight begins to leaking with lube and pre-cum.
Izuku's dick was still hard, standing up proudly, and Katsuki's eyes were locked on it like a predator. The thick, flushed length glistened with lube, the tip still wet with pre-cum. Izuku smirked, watching Katsuki's reaction.
"Looks like you're enjoying the show," Izuku teased, his voice low and husky. He slowly ran his fingers along the length of his cock, spreading the slickness. "Care to join?"
Katsuki's red eyes darkened as he watched Izuku's fingers trace his own cock. He could feel his own pulse quickening, his body reacting to the sight of Izuku's arousal.
"S...so, what IS it?" Katsuki tried to hide his excitement, but his tongue already confuses to make words right. Katsuki grabbed flashlight and looked closer, waiting for answer.
"What the hell is this thing?" He turned it over in his hands, examining the smooth surface and the way it curved inward. His fingers traced the ridges inside, his expression shifting from curiosity to something darker, something hungrier. "You really like this, huh?"
Izuku smirked, watching Katsuki’s fingers explore the toy. "Yeah, I do," he admitted, his voice low and teasing. "It’s got a good grip, you know? Just the right amount of pressure." He shifted on the bed, his cock still hard and glistening in the dim light. "You ever tried one?"
Katsuki’s red eyes flickered up to meet Izuku’s, his expression unreadable.
The air between them was thick with tension, the kind that crackled like electricity before a storm. His fingers tightened around the toy, testing its weight, its texture. The way it felt in his grip made his pulse quicken, his breath hitch in his throat.
"The hell I would. I have both you and Shoto, I have no need in such toys" Katsuki dropped artificial vagina on Izuku's bed.
"Kacchan. You looks disappointed. Is it really because I missed training? Did you plan something after it?" Izuku stand up and hugged Katsuki from back, nuzzled in his shoulder.
Izuku's dick was still hard and hot, and Katsuki could feel it through his clothes. Izuku's hands slide to Katsuki's chest, tracing the hard muscles there. He could feel the way Katsuki's breath hitched, the way his body tensed under his touch. Izuku's lips brushed against Katsuki's ear, his voice low and teasing. "You're such a liar, Katsuki. I can feel how much you want this." His fingers trailed lower, tracing the waistband of Katsuki's pants before sliding beneath it. The heat of his skin was electric, the way his fingers curled around Katsuki's cock making him suck in a sharp breath.
"Izu..." Katsuki begins, but Izuku shut him up with short kiss.
"Kacchan. I know you always ready to challenge only you can bit. Here...I have one dildo, which I couldn't...take. It's too big. But I'm sure great hero Dynamite easily can handle that monster". Izuku's voice was teasing, but suddenly, without words but just from atmosphere, both Izuku and Katsuki understand, who get which role. This time, Katsuki receiver, but quirky.
He didn't want to admit it, but Izuku knew that Katsuki was secretly curious about this. He was always the one in control, always the one calling the shots. But Izuku could see the way his red eyes flickered with something darker, something hungrier when he looked at the toy. The way his fingers tightened around it, testing its weight, its texture.
Izuku's lips curled into a smirk as he reached for the toy, his fingers brushing against Katsuki's. "Come on, Kacchan," he murmured, his voice low and teasing. "You're not scared of a little challenge, are you?" His green eyes sparkled with mischief, daring him to take the bait.
Didn't wait for Katsuki's answer, Izuku went to wardrobe and started searching for "that" toy. He on purpose took out different dildos, different sizes and shapes, before found dildo he looking for.
It was the biggest one in his collection. Katsuki's eyes widened slightly as Izuku pulled out the massive, veined silicone toy. It was thick, heavy, and curved slightly at the tip—designed to hit all the right spots. The sight of it made Katsuki’s breath hitch, his fingers twitching at his sides.
Izuku turned back to him, holding the dildo with a smirk. "This one," he said, his voice low and teasing. "I couldn’t even take the tip before I had to stop. But you? You’re *Dynamite*. You can handle anything."
Katsuki’s red eyes burned into him, his jaw tightening. "Challenge? What about reward, nerd?" Katsuki managed to say.
"Reward, ha?" Izuku grinning. He went closer to Katsuki and whispering on his ear:"As a reward you will take my dick inside your little ass hole".
Izuku's voice was low and teasing, his breath hot against Katsuki's skin. The blonde's body tensed, his fingers curling into fists at his sides. But there was something in his eyes—something dark, hungry—that betrayed his excitement.
"Fine," Katsuki growled, his voice rough with challenge. "But you better make it worth my time, Deku." His red eyes burned with defiance, but there was a flicker of something else beneath it—something that looked almost like anticipation.
Izuku smirked, his fingers tracing the line of Katsuki's jaw. "Oh, I will," he promised, his voice low and husky. "Trust me, Kacchan.
You're gonna love this." Izuku's fingers traced the curve of Katsuki's jaw, feeling the faint stubble there. His green eyes sparkled with mischief as he watched the blonde's reaction, the way his red eyes darkened with a mix of challenge and something deeper, something hungrier.
Katsuki went on Izuku's bed, trying to hide blushing face. He quickly pulled down pants and underwear.
"Do you need help with preparing, Kacchan?" Izuku purr, lying on bed close to Katsuki.
He slowly traced his fingers down Katsuki's chest, feeling the way his muscles tensed under his touch. "You're so tense, Kacchan," he murmured, his voice low and teasing. "Let me help you relax."
Katsuki's breath hitched as Izuku's fingers brushed against his skin, the heat of his touch sending a shiver down his spine. He could feel the way his body reacted, the way his cock twitched at the slightest touch. The blonde's fingers curled into fists at his sides, his jaw tightening as he tried to maintain some semblance of control.
"I...can do it... myself" Katsuki said, but his fingers trembling, massaging his own entrance.
Izuku smirked, watching Katsuki's struggle.
Izuku leaned in closer, his breath hot against Katsuki's ear. "Kacchan," he whispered, his voice smooth and teasing. "Let me help you. You know you want it." His fingers trailed lightly down Katsuki's spine, feeling the tension in his muscles, the way his body reacted to even the slightest touch.
Katsuki's breath hitched, his fingers stilled at his entrance. He could feel the heat of Izuku's body pressed against his back, the way his fingers traced patterns on his skin. The blonde's red eyes flickered with a mix of defiance and something darker, something that made his pulse quicken.
Izuku needn't Katsuki's answer. After all, this time he is in charge. Izuku just removed Katsuki's hand and slowly put two fingers inside, oiled and ready to stretch Katsuki's ass hole.
Katsuki's body tensed, his muscles clenching around Izuku's fingers. The sensation was unfamiliar, intense, and it made his breath hitch.
"Relax, Kacchan," Izuku murmured, his voice low and soothing. His fingers moved slowly, carefully, stretching Katsuki open with practiced ease. "You’re doing so well."
Katsuki’s jaw tightened, his fingers gripping the sheets beneath him. He could feel the heat of Izuku’s body pressed against his back, the way his breath ghosted over his skin. The blonde’s mind raced, torn between the unfamiliar sensation and the undeniable thrill of surrendering control.
"Fuck" moaning Katsuki, his voice was so high, it was rare to hear.
Izuku smirked, watching the way Katsuki's body reacted to his touch. The blonde's muscles were tense, his fingers gripping the sheets so tightly that his knuckles turned white. But beneath that tension, there was something else—a flicker of pleasure, a shiver of anticipation.
"You're doing so well, Kacchan," Izuku murmured, his voice low and soothing. "Just relax. Let me take care of you."
Katsuki's breath hitched as Izuku's fingers brushed against a spot inside him that made his entire body jerk. His red eyes widened, his lips parting on a silent gasp.
"Izu—!" Katsuki’s voice cracked, his body arching involuntarily as Izuku’s fingers found that spot again. The sensation was overwhelming, a sharp jolt of pleasure that made his cock twitch against his stomach.
Izuku chuckled softly, his breath warm against Katsuki’s ear. "See? You like it," he murmured, his fingers curling slightly to press deeper. "You’re so tight, Kacchan. But you’ll take it for me, won’t you?"
Katsuki’s fingers clenched the sheets, his knuckles white. "Shut up," he growled, but there was no real heat in it.
Katsuki didn't realise, but inside him was already four Izuku's fingers.
Izuku was stretching him, preparing him for the massive dildo. Katsuki's body was trembling, his breath coming in short, ragged gasps. His fingers were still clenched in the sheets, his knuckles white from the force of his grip. The sensation of Izuku's fingers inside him was overwhelming—unfamiliar yet undeniably pleasurable, a mix of pressure and heat that sent shivers down his spine.
Izuku's voice was low and teasing as he murmured, "You're doing so well, Kacchan. Just relax."
Katsuki moans with low voice. His dick, hard and leaking, twitching with need, but neither Katsuki and Izuku touched it. Tonight, Katsuki can receive pleasure only by his ass hole.
Finally, Izuku decided that Katsuki is ready.
He slowly withdrew his fingers, making Katsuki gasp at the sudden emptiness. The blonde’s body trembled, his muscles still clenched tight from the unfamiliar stretch.
Izuku smirked, watching the way Katsuki’s chest heaved with each ragged breath. “You’re doing so well, Kacchan,” he murmured, his voice low and teasing. “But we’re not done yet.”
He reached for the massive dildo, coating it generously with lube. The silicone glistened under the dim bedroom light, thick and intimidating. Katsuki’s red eyes widened as he watched Izuku’s fingers work, his throat bobbing nervously.
The dildo looked even bigger now that it was slick with lube, the veins and ridges standing out in stark relief. He could feel his pulse hammering in his ears, his body tense with anticipation.
Izuku leaned in, his breath hot against Katsuki’s ear. “You’re gonna take this for me, Kacchan,” he murmured, his voice low and commanding. “Every inch.”
Katsuki swallowed hard, his fingers digging into the sheets. He could feel the heat of Izuku’s body pressed against his back, the way his fingers traced idle patterns on his skin.
Katsuki’s breath hitched as Izuku positioned the dildo at his entrance, the cool silicone pressing against his stretched hole.
"Breathe, Kacchan," Izuku whispered, his voice low and soothing. His free hand slid up Katsuki's chest, feeling the way his muscles tensed beneath his touch. "Just relax and let me in."
Katsuki’s jaw tightened, his fingers gripping the sheets so tightly that his knuckles turned white. He could feel the pressure of the dildo, the way it stretched him even wider than Izuku’s fingers had.
Izuku pushed dildo, and huge tip entered Katsuki.
Katsuki's breath came in short, sharp gasps as the thick silicone stretched him open. His fingers clenched the sheets, his knuckles turning white as he fought to relax. The sensation was overwhelming—pressure, heat, the slow, relentless invasion that made his entire body tremble.
"Fuck—!" Katsuki hissed, his voice tight with strain. His muscles clenched instinctively, resisting the intrusion. But Izuku was relentless, his hands firm on Katsuki's hips as he guided the toy deeper.
"Breathe, Kacchan," Izuku murmured, his voice low and soothing. He leaned down, gently biting Katsuki's shoulder, at yhe same time Izuku pushed dildo deeper.
Katsuki's back arched, his fingers clawing at the sheets as the thick silicone breached him. The stretch was intense, almost painful, but beneath it was something else—something hot and electric that made his cock twitch against his stomach.
"Fuck— Izuku—!" Katsuki gasped, his voice breaking as the toy sank deeper. His muscles trembled, his entire body tensed as he fought to accommodate the massive intrusion.
Izuku's fingers traced soothing circles on Katsuki's back, his lips brushing against the blonde's ear. "You're doing so well, Kacchan," he murmured, his voice low and steady.
"And you like it, Kacchan. Loves when your little hole is fucked by something big, doesn't you?". Izuku voice was low.
Katsuki's breath was coming in short gasps, his fingers digging into the sheets as the dildo pressed deeper. The stretch was intense, almost overwhelming, but beneath it was something else—a dark, intoxicating pleasure that made his cock throb. His body trembled, his muscles clenching around the thick silicone.
Katsuki couldn't say anything, but his body talking: however dildo wasn't inside even on half, Katsuki's hips begins slowly moving, meeting huge toy.
His red eyes were half-lidded, his lips parted as he panted through the stretch. The sensation was overwhelming, but beneath the discomfort was a growing heat, a dark pleasure that coiled low in his stomach.
Izuku watched him with a satisfied smirk, his fingers tracing slow circles on Katsuki's lower back. "That's it, Kacchan," he murmured, his voice low and encouraging. "Take it like a good boy."
Katsuki's breath hitched at the words, his body reacting instinctively. His cock, already hard, twitched against his stomach, leaking pre-cum onto the sheets.
Katsuki's head went back, with low moans he begins thrusting, meeting dildo. Katsuki's face expressing pure pleasure. Izuku begins to push dildo deeper too, quickly making it's way in Katsuki's ass hole.
"M...Mo... Izu, give mooore" Katsuki cry, when dildo forcefully hits Katsuki's prostate.
Katsuki's body arched like a bow, his fingers clawing at the sheets as pleasure exploded through him. His cock throbbed, pre-cum dripping steadily onto the bed, but neither of them touched it - tonight, Katsuki's pleasure came only from his stretched, aching hole.
Izuku's smirk deepened as he watched Katsuki writhe. "You like that, don't you?" he murmured, his voice low and teasing. His free hand trailed down Katsuki's back, feeling the way his muscles trembled beneath his touch.
Dildo was just on 3/4 inside Katsuki's ass, but it stops. There wasn't space anymore. Then, Izuku begins thrusting dildo inside Katsuki. He put other hand on Katsuki's belly, and felt how dildo makes noticeable belly bulge with each thrust.
Izuku's fingers traced the outline of the silicone toy through Katsuki's skin, feeling the way it moved inside him. The blonde's breath came in ragged gasps, his body trembling with each deep thrust.
"You're taking it so well, Kacchan," Izuku murmured, his voice low and approving. His fingers pressed gently against Katsuki's lower belly, feeling the way the dildo stretched him from the inside. "Look at you - so full, so perfect."
Katsuki's red eyes were half-lidded, his lips parted as he panted through the overwhelming sensations. The stretch was intense, almost painful, but beneath it was a growing heat that coiled low in his stomach.
"Look, it reaching so far, imagine if me and Shoto will fill you, where will we reach?" Izuku purr, tickling Katsuki's belly.
"Imagine how much deeper you could take it if you just relaxed a little more."
Katsuki's breath hitched, his fingers clawing at the sheets. "Ngh...shut up," he managed, but there was no real bite to his words. His body was betraying him, his hips rolling in small, needy circles as Izuku's fingers traced the bulge in his belly. The sensation was overwhelming, a mix of pressure and pleasure that made his cock throb painfully.
Izuku leaned down, his breath hot against Katsuki's ear. "You want more, don't you?" he whispered, his voice low and teasing.
"You want to feel how deep you can really take it, don't you?"
Katsuki's red eyes flickered with defiance, but his body betrayed him. His hips rolled again, pushing back against the dildo, his ass clenching around it. The stretch was intense, almost too much, but the pleasure was undeniable.
"Fuck! Just fuck me already, Izu..." Katsuki moans, he surrendered. He couldn't stop his orgasm, it exploded inside him.
Katsuki's body arched violently, his fingers clawing at the sheets as pleasure ripped through him. His cock throbbed, thick ropes of cum spilling onto the bed in hot, sticky spurts. His entire body trembled as wave after wave of ecstasy crashed over him, his muscles clenching around the thick silicone buried deep inside him.
Izuku watched with satisfaction, his fingers still tracing slow circles on Katsuki's trembling back. "That's it," he murmured, his voice low and approving. "Let go for me, Kacchan."
Katsuki, exhausted, slowly fell on bed, still with dildo deeply inside.
"I...took it, nerd" Katsuki managed to say. "Where is my... reward?".
Katsuki's voice was a low rasp, his body still trembling from the aftershocks of his orgasm. His red eyes were half-lidded, his chest heaving as he tried to catch his breath. The massive dildo remained buried inside him, its thick girth stretching him obscenely, a constant reminder of what he had just taken.
Izuku smirked, his fingers trailing down Katsuki’s sweat-slicked back. He could feel the heat radiating off the blonde’s skin, the way his muscles still twitched with residual pleasure. "Oh, you *did* take it," Izuku murmured, his voice low and teasing.
"I didn't expect you still want to get your reward. But for you - anytime!". Katsuki heart how Izuku unpacked condom.
Izuku's hands were steady, deliberate, as he rolled the latex down his thick length. The sound of the wrapper crinkling filled the quiet room, mixing with Katsuki's ragged breaths. The blonde's red eyes followed every movement, his body still trembling from the aftershocks of his orgasm, the massive dildo still buried deep inside him.
Izuku with sudden roughness withdrew dildo from Katsuki in one move.
Katsuki moaned, his body arching as the thick silicone slid out of him, leaving him feeling strangely empty. His ass clenched around nothing, still pulsing with the aftershocks of his orgasm. The room was filled with the sound of their ragged breaths, the air thick with the scent of sweat and sex.
Izuku's green eyes gleamed with satisfaction as he watched Katsuki's reaction. He leaned down, his lips brushing against Katsuki's ear. "You took that so well, Kacchan," he murmured, his voice low and teasing.
"Now it's my turn."
Izuku's fingers traced the curve of Katsuki's hip, feeling the way his muscles trembled beneath his touch. The blonde's body was still flushed from his orgasm, his skin glistening with sweat. Izuku could see the way Katsuki's fingers clenched the sheets, the way his breath hitched as he waited for what came next.
Izuku positioned himself between Katsuki's legs, his cock hard and ready. He leaned down, his breath hot against Katsuki's ear. "You're all mine now, Dynamite," he whispered, his voice low and commanding.
The words sent a shiver down Katsuki's spine, his body instinctively arching up to meet Izuku's touch.
"Don't be gentle, Izu..." Katsuki moans. "Please...".
Izuku grabbed Katsuki's hair and pull him closer. "Do you begging for it, Kacchan?" Izuku was demanding.
He wanted to see Katsuki break apart for him. He wanted to hear him beg, to feel him surrender completely. His fingers tightened in Katsuki's hair, pulling just enough to make the blonde gasp.
"Say it," Izuku growled, his voice rough with need. "Tell me what you want."
Katsuki's red eyes burned with defiance, but his body betrayed him. His hips rolled up, seeking friction, his cock already half-hard again despite the intensity of his last orgasm.
"I want you to fuck me," Katsuki finally admitted, his voice rough and raw. "Hard.
Fast. Don't hold back." Katsuki's voice was a low growl, his fingers digging into the sheets as he arched his back, offering himself completely. The words hung in the air between them, thick with challenge and need.
Izuku's green eyes darkened, his grip tightening in Katsuki's hair as he leaned down, his lips brushing against the blonde's ear. "Since you asked so nicely," he murmured, his voice a dark purr. His free hand slid down Katsuki's chest, tracing the hard lines of his muscles before gripping his hip possessively.
Izuku slapped Katsuki's buttock, and roughly entered him on full length.
Katsuki's body trembled, his fingers clawing at the sheets as Izuku's thick cock stretched him open. The sensation was overwhelming—heat, pressure, the relentless invasion that made his entire body arch off the bed. His back arched, his fingers clawing at the sheets as pleasure and pain tangled together in a dizzying rush. His cock throbbed against his stomach, already leaking pre-cum in thick, sticky drops. Katsuki gasped, his voice breaking as Izuku bottomed out inside him. His muscles clenched instinctively, resisting the stretch, but Izuku was relentless, his hips rolling forward in slow, deliberate thrusts that made Katsuki see stars.
"How it feels? Better then silicone, ha?" Izuku begins thrusting quickly and reaching Katsuki's prostate sith each push.
His hand on Katsuki's hip was firm, possessive, pulling him back to meet each thrust with a sharp snap of his hips.
"Fuck—! Izu—!" Katsuki's voice cracked, his fingers clawing at the sheets as Izuku's cock pounded into him. The stretch was intense, almost unbearable, but beneath the burn was a deep, throbbing pleasure that made his cock twitch and leak against his stomach. His body trembled, his muscles clenching around Izuku's thick length as the younger hero fucked him with relentless precision.
Izuku slapped Katsuki's buttock again, demanding:"Say! Is it better then silicone one?".
Izuku's voice was low, teasing, with a hint of dominance that sent shivers down Katsuki's spine.
Katsuki's breath came in ragged gasps, his fingers clawing at the sheets as Izuku's cock hit that spot inside him over and over. The pleasure was overwhelming, a sharp jolt of ecstasy that made his body jerk with each thrust. Y-Yeah—! It's—!" Katsuki panted, his voice breaking as Izuku's hips snapped against his ass. His cock throbbed painfully, leaking pre-cum onto the sheets.
"Fuck! Kacchan, your hole even after my middle size toy still so tight!" Izuku groaned, made his speed even quicklier.
"W..wha..? M... Middle?" Katsuki couldn't form whole sentence, he was focused on Izuku's dick.
He felt like his body was on fire, every nerve ending alight with pleasure. The way Izuku's cock stretched him open, filling him completely, was unlike anything he'd ever experienced. The silicone toy had been intense, but this—this was something else entirely.
"Fuck, Izu—!" Katsuki gasped as Izuku's hips slammed into him, the force pushing him forward on the bed. His fingers clawed at the sheets, his body trembling with each powerful thrust. The pleasure was overwhelming, a deep, throbbing heat that coiled low in his stomach and radiated outward.
Izuku's breath was hot against his ear, his voice rough with need.
"Next time I'll use really the bigger dildo from my collection. Want Shoto looks too. He would love the view!".
Izuku's voice was husky and teasing, his thrusts never slowing as he spoke. His fingers dug into Katsuki's hips, pulling him back to meet each snap of his hips. The room was filled with the sound of skin slapping against skin, the wet, obscene noises of their bodies moving together.
Katsuki could only moan in response, his mind too fogged with pleasure to form words. His cock was painfully hard, leaking steadily onto the sheets beneath him. Every time Izuku's hips slammed into him, his cock twitched, desperate for touch but denied. The blonde's body was a live wire, every nerve alight with sensation.
To explosion wasn't enough one spark. And Izuku make it. He bite Katsuki's neck, deeply, not gently, that mark left on long time noticeable.
Izuku's teeth sank into the tender flesh of Katsuki's neck, his breath hot and ragged against the blonde's skin. The sharp sting of pain mixed with the overwhelming pleasure, sending Katsuki's body into overdrive. His fingers clawed at the sheets, his back arching as he let out a broken moan.
Katsuki came second time. It was hurricane.
Katsuki's body trembled, his muscles clenching around Izuku’s cock as pleasure ripped through him in violent waves. His cock throbbed, thick ropes of cum spilling onto the sheets in hot, sticky spurts.
His voice was unrecognisable, he moans, cried, begging, screaming at the same time.
His body shook like he was electrocuted, his fingers clawing at the sheets, his back arching violently as pleasure tore through him. His cock pulsed, thick ropes of cum painting the sheets beneath him, his muscles clenching around Izuku’s cock in rhythmic spasms.
Izuku’s grip on Katsuki’s hips tightened, his thrusts becoming erratic as he chased his own release. The sight of Katsuki coming undone beneath him, the way his body trembled and his voice broke, was almost enough to send him over the edge.
The real reward was it. Izuku groaned, and allowed himself to release his seed inside Katsuki. His hips stuttered as he bottomed out, his cock throbbing as he emptied himself deep inside the blonde. The sensation was overwhelming—the tight, hot clench of Katsuki’s body, the way his muscles fluttered around him as he came down from his own orgasm.
Katsuki collapsed forward onto the bed, his body trembling, his breath coming in ragged gasps. His skin was slick with sweat, his muscles still twitching from the force of his release. Izuku leaned down, pressing a soft kiss to the back of Katsuki’s neck, his fingers tracing idle patterns on the blonde’s hip.
Izuku lie next to Katsuki, slowly licking his deep bite mark.
The blonde’s skin was still flushed, his breathing uneven as he lay sprawled across the bed, utterly spent. The sheets were a mess of sweat and cum, the scent of sex thick in the air. Katsuki’s fingers twitched against the fabric, his body still trembling with aftershocks.
Izuku smirked, his fingers tracing lazy circles on Katsuki’s hip. "You took that better than I expected," he murmured, his voice low and teasing. "Maybe next time, we’ll try something even bigger."
Katsuki let out a weak groan, his red eyes half-lidded as he turned his head slightly to glare at Izuku.
"Why it's always me? Shoto should suffer too!" Katsuki complains, but he was satisfied with experiment.
He didn't want to admit it, but Izuku's fingers stretching him open, the way his body had trembled with pleasure, was something he couldn't easily forget. The blonde's red eyes flickered with something darker, something that made his pulse quicken.
Izuku chuckled softly, his fingers tracing the curve of Katsuki's jaw. "You're just jealous because Shoto got to watch last time," he teased, his voice low and playful. "But don't worry, Kacchan. I'm sure he'd love to join us next time."
Katsuki's breath hitched at the thought, his fingers curling into fists at his sides.
Izuku suddenly changed on face. "Or maybe, I crossed the line, Kacchan? You didn't hurt?".
Izuku asked, his voice suddenly soft and sincere.
Katsuki's red eyes flickered with something unreadable, his jaw tightening. The blonde's fingers twitched against the sheets, his body still trembling from the aftershocks of his orgasm. The deep, lingering ache in his ass was a constant reminder of what had just happened - of how thoroughly Izuku had claimed him.
Izuku's fingers traced gentle circles on Katsuki's hip, his touch careful and attentive. "Kacchan?" he prompted, his voice low and concerned. "Are you okay?"
"Dumb nerd. Of course I can handle even more!" Katsuki answered. After that, he quietly added:" You were fucking perfect, Izu".
Katsuki's voice was low, almost a whisper, but the words hung in the air between them, thick with something raw and vulnerable. His red eyes flickered up to meet Izuku's, and for once, there was no challenge in them—only honesty.
Izuku's breath caught in his throat. He had seen Katsuki in so many moods—angry, competitive, cocky—but this quiet, almost shy version of him was something new. Something rare. His fingers traced the curve of Katsuki's jaw, feeling the faint stubble there. "You were pretty perfect yourself," he murmured, his voice soft.
Izuku leaned in, pressing a gentle kiss to Katsuki's shoulder. His lips lingered there, tasting the salt of sweat and the faint metallic tang of blood from where he'd bitten down earlier. The mark was already darkening, a deep purple bruise that would linger for days—a reminder of this moment.
Katsuki turned his head slightly, his red eyes meeting Izuku's. There was something unreadable in them, something that made Izuku's chest tighten. The blonde's fingers twitched against the sheets, his body still trembling faintly from the aftershocks of their encounter.
Izuku's hand slid up Katsuki's back, his fingers tracing the hard lines of his muscles.
"Let's sleep, Izu. You worked hard". Katsuki hugged Izuku and nuzzled in his collarbone.
His red eyes were soft, almost sleepy, as he let out a slow exhale. The tension that usually radiated from him like a force field had melted away, replaced by something softer—something rare.
Izuku's fingers traced lazy patterns on Katsuki's back, feeling the way his muscles relaxed under his touch. The room was quiet except for the sound of their breathing, the air thick with the scent of sweat and sex. The setting sun had long since faded, leaving the room bathed in the soft glow of the bedside lamp.
Katsuki's voice was muffled against Izuku's shoulder.
