"Fuck, not now!" Bakugou hissed angrily, ducking into an alleyway as his stomach cramped up viciously. He was early, his Heat was early. Tears pinpricked his vision, half in pain and half in frustration. He needed to get home but his phone was dead and the walk home would grow more and more impossible the longer he tried. He stumbled to his feet, nausea making his cramping stomach roll uncomfortably. He shrunk back against the brick wall of the building behind him for a moment.

That was when he smelt them.

Both of their scents were strong and so, so tantalizing. One was pine and cedar with a hint of sage, all encompassing. A tinge of Rut already seeping into it, an Alpha. The other was woodsmoke and rain but more reserved, a Beta. Bakugou's head swiveled in the direction that the scents were stronger, finding two men at the mouth of the alleyway.

The tallest (there was no way he was that fucking huge, Bakugou had to be dreaming) had a fluffy mess of green curls, equally green eyes, and freckles along his cheeks. His shirt was probably a size or two too small and he had on a pair of joggers with red shoes, leaving nothing to the imagination of how toned he was.

The other man, the Beta, had an even more striking appearance. He was shorter than the Alpha but still taller than Bakugou. His hair was long, his bangs touching his nose, and bicolored- the right side white like snow and the left crimson. His left eye was turquoise, the right a brownish grey. Bakugou had only seen eyes like that on television or in science textbooks. There was a large scar on the left side of his face- a burn. He wore a dark blue jacket with elbow length sleeves, the collar was high and joined in the center by a grey neck piece (fuck, did he not have anything on underneath?), with baggy pants of the same color and white boots.

They stood still for a moment before approaching slowly, cautiously. The Alpha knelt down next to him, offering his wrist.

"Hello, Omega." He greeted. His voice was deep but nice... cheery even. Bakugou whined in response, hands coming up to grab hold of the Alpha's wrist and shove his nose against the glands there. He was slipping faster with them there. "Is this your first Heat?" Bakugou shook his head. "What's your name? How old are you? Do you know what today's date is?"

"Bakugou. I'm Bakugou Katsuki." The Omega answered. "I'm twenty-one and it's the fifteenth of March."

"That's good, you're still lucid." The Alpha praised. "You're such a good Omega, Kacchan." Bakugou felt his face heat up as he purred happily. The Alpha crooned in response.

"Alpha." The Beta called, grabbing both their attentions. His voice was deep- deeper than the Alpha's even- but calm, reserved like his scent. "We need to get him somewhere safe." The Alpha nodded before turning back to Bakugou and asking him where to go. Bakugou rattled off his address without a second thought. The Alpha scooped him up effortlessly and Bakugou let his scent wrap around him, soothing the Heat.

He woke up just as they reached his door, Heat flaring to full affect. The Alpha's Rut was getting closer too. He was surprised the Beta was still sane and coherent with the combined smells so strong around him. It took Bakugou three tries to get the key in the front door but he managed, the Alpha crooning in praise as the door opened. The apartment was empty, his friends all either at work or out somewhere.

"Katsuki?" The Beta murmured, a strain to it. "You probably want to nest, yes?" Bakugou nodded, Heat making his movement sluggish, and made his way to his bedroom as quickly as possible. "Alpha." He heard the Beta say. "It's important to provide for our Omega, he's going to need lots of food and water." He heard the Alpha rumble in response.
