Burning Yearn: An Omega's Desire

Chapter 1: Unspoken Heat

Izuku Midoriya stood in the middle of the bustling hero agency, his emerald eyes darting toward the explosive blond who had haunted his dreams since childhood. Katsuki Bakugo, all sharp edges and raw power, was barking orders at some rookie heroes, his voice a low growl that sent an involuntary shiver down Izuku’s spine. At four months pregnant, Izuku’s body was a chaotic storm of hormones and unspoken desires, his Inner Omega clawing at the edges of his mind, whispering that Katsuki was *his*. He clenched his fists, trying to shove the thought down, but damn it, Katsuki looked *good*—sweat glistening on his brow, muscles flexing under his tight hero suit. Too good.

'Deku, you’re staring again,' Katsuki snapped, his crimson eyes locking onto Izuku with an intensity that made his knees weak. He strode over, closing the distance between them in seconds, his presence overwhelming. 'What the hell’s wrong with you lately? You’ve been off your game for weeks.'

Izuku swallowed hard, his heart racing as he tried to keep his voice steady. 'I’m fine, Kacchan. Just... tired. You know, with everything.' He gestured vaguely at his slightly rounded belly, hoping it would deflect the conversation. But Katsuki’s gaze didn’t waver, piercing through Izuku’s flimsy excuse like a knife.

'Tired, my ass,' Katsuki scoffed, stepping closer until Izuku could feel the heat radiating off him. 'You think I don’t notice? You’re distracted. You’re *different*. And I’m not some idiot who’s gonna ignore it.' His voice dropped, a dangerous edge to it. 'So spill it, nerd. What’s eating at you?'

Izuku’s breath hitched, his body betraying him as a flush crept up his neck. He could smell Katsuki’s scent—smoky, intoxicating, like a fire just waiting to consume him. His Inner Omega screamed, desperate to close the gap, to feel those rough hands on his skin. 'Kacchan, I—I can’t,' he stammered, taking a step back, only to find himself pressed against the cold wall of the agency hallway. Nowhere to run.

Katsuki’s lips curled into a smirk, predatory and knowing, as he caged Izuku in with one arm against the wall. 'Can’t what, Deku? Can’t tell me you’ve been eye-fucking me for weeks? Can’t admit you’re a mess right now?' His other hand hovered near Izuku’s hip, not touching, but close enough to make Izuku’s skin tingle with anticipation. 'I’m not blind. I see the way you look at me. So what’s stopping you?'

Izuku’s resolve crumbled under the weight of Katsuki’s words, his body aching with a need he’d suppressed for too long. 'You don’t get it,' he snapped, his voice sharp despite the tremor in it. 'I’ve spent years trying to move on, trying to forget how much I want you. And now, with everything—' He cut himself off, biting his lip, but the heat pooling in his core was undeniable, his body practically begging for Katsuki to close the distance. 'I’m not some damsel, Kacchan. I don’t need saving. But I... I can’t stop wanting you.'

Katsuki’s eyes darkened, a low growl rumbling in his chest as he leaned in, his breath hot against Izuku’s ear. 'Good. ‘Cause I’m done pretending I don’t want you just as bad.' His hand finally made contact, gripping Izuku’s waist with a possessive strength that made him gasp. 'You’re mine, Deku. Always have been.'

Izuku’s mind spun, his body igniting at the words, his Inner Omega howling in triumph. He tilted his head back against the wall, exposing the vulnerable line of his neck, a silent invitation. Katsuki’s lips hovered just above his skin, teasing, testing, and Izuku knew—there was no turning back from this heat, this burning yearn that threatened to consume them both.
