Heated Instincts: An A/B/O Tale

Chapter 1: Uncontrollable Urges

The dorm room was a cocoon of dim light and muffled movie dialogue, the flickering screen casting shadows over Amami Rantaro’s bed where he and Naegi Makoto sat, nestled close. Amami’s arm draped casually over Naegi’s shoulder, a gesture of easy camaraderie that had become second nature during their time at Hope’s Peak. The air was warm, comfortable—until it wasn’t.

Naegi shifted slightly, his body suddenly hyper-aware of the alpha beside him. Amami’s scent, a heady mix of cedar and something primal, was seeping into his senses, curling around his nerves like a vice. His heart raced as a realization hit harder than a punch: his heat. He’d forgotten his suppressants, too caught up in exams and late-night talks. And now, with Amami’s touch burning through his thin shirt, Naegi felt the telltale ache, the undeniable hardness straining against his jeans. *Fuck.*

“You okay, man?” Amami’s voice cut through the haze, smooth and concerned, his green eyes flicking from the screen to Naegi. “You’re squirming like you’ve got ants in your pants.”

Naegi forced a laugh, but it came out shaky, brittle. “Yeah, just... getting comfy. Movie’s intense, huh?”

Amami smirked, oblivious for the moment. “If by intense you mean predictably cheesy, sure. I could write a better plot in my sleep.”

But then, Amami’s nose twitched. His casual grin faltered as the air thickened with something sweet, desperate—Naegi’s pheromones. The scent hit him like a freight train, flooding his senses, igniting every alpha instinct buried deep. His jaw clenched, fingers tightening on Naegi’s shoulder before he forced himself to loosen his grip. *Shit. He’s in heat.*

“Naegi,” Amami said, voice low, strained. “I think... I should walk you back to your dorm. Now.”

Naegi didn’t respond, couldn’t. His face was already buried in the crook of Amami’s neck, inhaling deeply, greedily, as if the alpha’s scent was the only thing keeping him grounded. “God, you smell so good,” he mumbled, voice thick with need, completely ignoring Amami’s words.

Amami’s breath hitched, his body trembling with the effort to hold back. His hands hovered, half-wanting to push Naegi away, half-screaming to pull him closer. “Naegi, listen to me. You’re not thinking straight. This isn’t—fuck, you’re a virgin, aren’t you? You don’t want this, not like this, not with me—”

But Naegi wasn’t listening. His hips jerked instinctively, grinding against Amami’s thigh, a desperate whine escaping his lips as he tugged at Amami’s belt. “It hurts, Rantaro. It *hurts* so much. Please, make it stop. I need you.”

Amami’s control was a fraying thread, his alpha rut kicking in hard, fueled by Naegi’s scent and those pleading words. His eyes darkened, pupils blown wide, as Naegi turned, getting on his stomach, face down on the bed. He arched his back, raising his ass in the air—an offering, a submission that shattered Amami’s last restraint. Slick was already dripping, the scent of Naegi’s heat-soaked arousal making Amami’s cock throb painfully in his jeans.

“Naegi, damn it,” Amami growled, voice raw, hands shaking as he gripped the omega’s hips. “You’re gonna regret this. You’re gonna hate me.”

“I won’t,” Naegi sobbed, pushing back against him, desperate and horny. “Alpha, please. I’m so wet, I can’t— I need you inside me. Now.”

That word—*Alpha*—snapped something primal in Amami. With a guttural curse, he yanked Naegi’s pants down, exposing that dripping, ready hole. His own jeans were off in a heartbeat, his hard cock springing free, already leaking at the tip. There was no need for prep; Naegi’s body was made for this, slick and open, begging to be filled. Amami positioned himself, the heat of Naegi’s ass against his tip driving him insane.

“You’re mine,” Amami snarled, possessive instincts roaring as he leaned over, licking a stripe up Naegi’s neck, scenting him. “No one else gets to touch you. Ever.”

Naegi whimpered, panting, sweating under him. “Yes, Alpha. Just—fuck me. Please.”

And with that, Amami thrust in, hard and deep, the tight, wet heat of Naegi’s pussy-like hole swallowing him whole. The room filled with the sound of skin slapping, Naegi’s moans, and Amami’s feral grunts, the bed creaking under the force of their need. This was only the beginning.
