Izuku Midoriya’s small apartment was a chaotic shrine to heroics, cluttered with stacks of notebooks filled with scribbled observations, All Might posters peeling at the edges, and a laundry pile that had long since declared independence. The air was thick with the faint, sweet musk of an omega on the cusp of heat, a scent that clung to every corner of the room despite Izuku’s frantic attempts to mask it with cheap air freshener. He darted around, shoving socks under the couch and tossing notebooks into a drawer, his hands trembling with a mix of nerves and the creeping heat that prickled under his skin.
“Damn it, why now?” he muttered to himself, wiping sweat from his brow. His green eyes flicked to the clock—any minute now, Katsuki would show up, and Izuku knew he wasn’t ready for the storm that was about to blow through his door. His heat was creeping closer, a slow burn that made his knees weak and his thoughts fuzzy. He needed to play it cool, act like everything was fine, even if his body was screaming otherwise.
The door slammed open with a force that rattled the walls, and in stormed Katsuki Bakugo, all sharp edges and alpha dominance. His scent hit Izuku like a freight train—smoke and spice and raw power, cutting through the omega’s fragile composure. Izuku’s knees buckled for a split second, a gasp catching in his throat as he gripped the edge of the table for support.
“Oi, nerd, you gonna invite me in or just stand there lookin’ like a deer in headlights?” Katsuki’s rough voice sliced through the silence, a smirk tugging at his lips as he leaned casually against the doorframe, crimson eyes glinting with mischief.
Izuku’s face flushed a deep red, his voice cracking as he tried to muster some semblance of control. “Y-You could’ve at least texted, Kacchan! Barging in like you own the place—what if I wasn’t even home?”
Katsuki’s smirk widened, predatory and dangerous, as he crossed his arms over his broad chest. “Tch, don’t gimme that crap. I can smell you from a mile away, Deku. You’re already a blushing mess, and I ain’t even touched ya yet.”
Izuku’s jaw tightened, embarrassment warring with the heat coiling in his gut. He straightened up, forcing a glare even as his body shivered under the weight of Katsuki’s gaze. “Shut up, you stupid, overbearing mutt. I’m fine. I don’t need you sniffing around like some feral dog.”
But Katsuki’s eyes darkened, catching the subtle shift in Izuku’s scent, the sweet edge of heat that was starting to bloom. He took a deliberate step forward, his boots heavy on the creaky floorboards, and a low growl rumbled in his chest. “Keep talkin’ smack, nerd, but your scent’s drivin’ me up the damn wall. You’re practically begging for me without sayin’ a word.”
Izuku’s breath hitched, his hands instinctively pushing against Katsuki’s chest as the alpha closed the distance between them. It was a half-hearted shove at best, his strength faltering as the heat clawed at his resolve. “I-I’m fine, Kacchan. I don’t need your help. I can handle this on my own,” he stammered, but his voice wavered, thick with a need he couldn’t hide.
Katsuki’s laugh was rough, a dangerous sound that sent a shiver down Izuku’s spine. In a flash, he had Izuku pinned against the wall, one hand braced beside the omega’s head, the other gripping his hip with bruising force. His breath was hot against Izuku’s ear as he whispered, “Oh, you’re gonna handle it, huh? I’m gonna help you through this, Deku. Gonna make you scream my name ‘til you can’t think straight. How’s that sound?”
Izuku’s resolve crumbled like a house of cards, his breath coming in short, desperate gasps as his body arched instinctively toward Katsuki. But his pride wasn’t completely gone—not yet. “Stop teasing, you loudmouth jerk,” he snapped, his voice trembling with a mix of frustration and raw desire. “If you’re gonna do something, then do it already!”
Katsuki grinned, a feral edge to it, and dragged his nose along the sensitive curve of Izuku’s neck, inhaling deeply. The omega’s scent was intoxicating, a drug that made his alpha instincts roar. “Oh, I’ll do plenty, nerd. But I wanna hear you beg for it first. C’mon, use that big brain of yours and ask nice.”
Izuku’s face burned, his mind a jumbled mess of heat and embarrassment. He stumbled over his words, fists clenching in Katsuki’s shirt as he fought against the overwhelming need. Finally, the words tumbled out, raw and broken. “P-Please, Kacchan… touch me. I—I need it. Please.”
The alpha’s grin turned triumphant, and he rewarded Izuku with a bruising kiss, lips crashing together with a hunger that left no room for hesitation. His hands roamed possessively, sliding under Izuku’s shirt to grip bare skin, and he pulled back just enough to taunt, “Look at you, already fallin’ apart under me. Pathetic, Deku. Thought you were tougher than this.”
Izuku’s eyes flashed with defiance even as his body melted into Katsuki’s touch, a shaky insult spilling from his lips. “S-Shut up, you cocky bastard. You’re not… not as good as you think you are.” But his hands betrayed him, clinging to Katsuki’s shoulders, desperate for more as the heat made every nerve in his body ache.
The tension in the room skyrocketed, clothes starting to come off in a frantic blur of motion. Katsuki’s growls mingled with Izuku’s soft whimpers, the air thick with the scent of heat and alpha dominance. Shirts hit the floor, hands grasping and pulling, the intensity building with every heated touch. Katsuki’s rough palms slid over Izuku’s trembling frame, claiming every inch as his own, while the omega’s gasps grew louder, more desperate.
But then, amidst the chaos, Katsuki paused. His alpha instincts roared, urging him to keep going, to take and claim until there was nothing left to give. Yet a flicker of concern flashed in his crimson eyes, a rare moment of restraint cutting through the haze. He pulled back slightly, his voice low and rough but laced with something softer. “Hey, nerd. You still good with this? I ain’t gonna push if you ain’t sure.”
Izuku blinked up at him, chest heaving, heat still burning in his veins. But in that moment, amidst the storm of desire, there was a flicker of clarity—a reminder that even in the wildest of moments, Katsuki cared. And that, more than anything, made Izuku’s heart stutter in a way that had nothing to do with his heat.
