Sunscreen and Suppressants

The hotel room smelled like coconut sunscreen and desperation. Miya Atsumu stood in front of the full-length mirror, turning side to side, tugging at the thin straps of his olive-green bikini top. The color matched his brother's swim trunks—they'd bought them together, one of those rare twin solidarity moments. Now it felt like a cruel joke.

Three suppressant patches layered along his collarbone like band-aids over a wound that wouldn't stop bleeding. His chest had been growing for months despite the blockers. Nothing stopped the inevitable.

"Ya ready?" Osamu's voice came from behind him. Flat. Familiar. His twin was already dressed in the matching trunks, a plain white t-shirt still covering his lean torso. Beta body. Uncomplicated. Unburdened.

Atsumu met his brother's eyes in the mirror. Same face. Same silver-brown hair. Same sharp jaw. But Osamu didn't have to worry about—about any of it.

" 'M always ready," Atsumu said, forcing a grin that didn't reach his eyes. His omega ears, hidden beneath a baseball cap, twitched. His tail, wrapped tight around his waist under the bikini bottom, felt like a coiled spring.

Osamu didn't say anything. He never did. Just watched with those quiet, observant eyes that saw too much and revealed too little.

The walk to the beach was short. The sun was brutal. Families and couples and groups of friends sprawled across the sand like offerings to some vengeful summer deity. Laughter rang out, sharp and carefree. Atsumu hated every single one of them.

He laid his towel down near the water's edge, damp sand cool against his palms. Osamu set up a few feet away—close enough to watch, far enough to pretend he wasn't.

Atsumu stripped off his cover-up. Olive green bikini. Simple. Elegant. He'd saved for weeks to buy it, told himself he looked good in it, told himself he had every right to wear it.

He did.

That didn't stop the eyes.

The first one came within minutes. A man in his late twenties, maybe early thirties, with sunburned shoulders and a wedding ring. He walked past, did a double take, circled back.

"Hey, beautiful. You here alone?"

Atsumu kept his eyes closed. "With my brother."

"Lucky brother. Can I get you a drink?"

"No."

"Just a drink. Come on, don't be shy—"

"He said no."

Osamu's voice cut through the heat like a blade. He hadn't moved from his spot, hadn't raised his voice, but the words landed hard. The man glanced at him, scoffed, and wandered off.

Atsumu exhaled. "I had it handled."

"I know."

Those two words again. Empty. Useless.

The second man came ten minutes later. A teenager, barely out of high school, bold in that way youth makes people stupid. He flopped down beside Atsumu's towel, grinning.

"Nice bikini. You on the volleyball team or something?"

"Professional," Atsumu said flatly.

"Wow, really? You must be loaded. Buy me lunch?"

"Get lost."

"Aw, don't be cold—"

"Brother," Osamu called out, not looking up from his phone. "Now."

The kid scrambled away like a startled crab.

It continued like that. A pattern. Sickening, exhausting.

Twelve minutes. A man in board shorts asked if Atsumu needed sunscreen applied to his back.

Fifteen minutes. A woman complimented his bikini, then asked if he was looking for a third in her relationship.

Twenty-three minutes. A group of college guys offered to take photos of him, their phones already out.

Each time, Osamu intervened. Each time, Atsumu felt his brother's presence like a leash. Protection or suffocation? He couldn't tell anymore.

The eighth man was the worst. He didn't speak. Just stood there, five feet away, staring at Atsumu's chest with that vacant hunger—like he'd forgotten Atsumu was a person. His eyes traced the curve of the bikini top, the swell of omega-soft skin that no amount of suppressants could flatten.

Atsumu's omega ears flattened beneath his cap. His tail bristled under the fabric. He wanted to cover himself. He wanted to scream. He did neither.

"Ya got a problem?" Osamu was on his feet now, blocking the man's view.

The man blinked, like waking from a trance. "What? No. Just looking."

"Look somewhere else."

"Touchy." The man shuffled away, but his eyes lingered until he was out of sight.

Atsumu's hands were shaking. He pressed them flat against the towel, trying to ground himself. Sand hot. Sun too bright. Every suppressant patch pulling at his skin, a constant reminder his body was a battlefield.

"Samu," he said, voice small.

"Yeah?"

"How many?"

A pause. "Eight."

"Two more and we can go." Atsumu had made a rule. Arbitrary. Stupid. But it gave him something to hold onto. Ten men. If ten men approached him, he was allowed to leave. If ten men approached him, it meant the universe was telling him he didn't belong here.

Nine came at the thirty-minute mark. A middle-aged man with a beer belly and a kind face that made the interaction worse. He offered a compliment—genuine, friendly—asked about his day. Atsumu answered stiffly. The man left after two minutes, satisfied and oblivious to the damage he'd done.

Number ten never came, because number ten had already happened twice without Atsumu counting them. The ones who touched him. The ones who crossed a line that couldn't be uncrossed.

The first touch had been five minutes ago. A hand on his shoulder, friendly enough. The man claimed he was trying to get his volleyball back, but his fingers lingered, dragging across Atsumu's skin like they had nowhere better to be.

The second touch was happening now.

Atsumu felt fingers brush against his ribcage, slide down to the curve of his waist, graze the edge of his bikini top before pulling away. The man muttered an apology—"Sorry, just trying to get past"—but his eyes were laughing.

Something inside Atsumu shattered.

He sat up so fast his vision swam. His omega ears tore free of the baseball cap, standing upright and trembling. His tail unraveled from its hiding place, bristling with distress. His chest heaved as the suppressant patches burned against his skin, overwhelmed by the surge of cortisol and adrenaline and shame.

"Can't I wear a bikini," he choked out, voice cracking like old glass, "without some asshole touching my chest?"

The words hung in the air. Raw. Unfiltered. The culmination of every sun-drenched horror story he'd told himself he was strong enough to endure.

Osamu looked at him.

Something in his brother's eyes shifted. The quiet, observant gaze that had watched Atsumu navigate this hell for a decade flickered, caught fire, and turned red.

It wasn't anger. Something deeper. Primal.

Atsumu saw his brother's pupils dilate. Saw the veins in his neck bulge. Saw his jaw tighten, fists clench, entire body coil like a spring about to snap.

Then everything went wrong.

Osamu's body trembled. His scent—usually neutral, barely there, that unremarkable nothing of a beta—changed. Bloomed outward, sharp and metallic, like ozone before a thunderstorm. Like lightning trapped in a jar.

His eyes rolled back.

He collapsed.

And then he was gone, and Atsumu was screaming, and the beach was spinning, and he didn't know if his brother was alive or dead, and the men were still watching, still staring, still seeing him as something to be touched.

Consciousness returned in stages.

First, the ceiling. Familiar. The water stain in the corner, shaped like a deformed cloud. His ceiling. His hotel room.

Second, the smell. Hit him like a freight train. Heavy. Overpowering. He knew that scent—smelled it a thousand times on alpha athletes, alpha teammates, alpha strangers. But it had never been his before.

Osamu sat up.

His body felt different. Larger. Shoulders ached with a new width, chest expanded with a new depth. His hands looked the same but felt stronger, more dangerous. More capable.

He lifted one to his face, turned it over. Smelled like him. Like the scent filling the room.

"Samu?"

Atsumu's voice. Small. Terrified.

Osamu turned. His brother curled up on the other bed, knees to chest, omega tail wrapped around his waist like a security blanket. Ears flat against his skull. Eyes wide and wet.

But it wasn't Atsumu's fear that caught him. It was his scent. The sweetness, the vulnerability, the way it called to something inside Osamu that had never existed before.

Protect.

The word resonated in his bones. Not a thought. An instinct.

" 'Tsumu." His own voice was deeper. Rougher. Like gravel and smoke. "I'm okay."

"Ya scared the shit out of me." Atsumu's voice wobbled. "Ya just—collapsed. I thought ya died. I thought—"

"I didn't die." Osamu swung his legs over the side of the bed. The floor felt closer. His body heavier. "I changed."

Atsumu's breath caught. "Changed how?"

Osamu didn't answer. Stood, walked to the bathroom mirror, stared at his reflection.

Same face. Same hair. Same jaw.

But different.

His eyes had a new glint—predatory sharpness that hadn't been there before. Shoulders broader, frame more imposing. And his scent—God, his scent—rolled off him in waves, thick and commanding. Undeniably alpha.

He smiled.

Not a gentle smile. The smile of someone who'd been given a weapon they didn't know they needed.

"I'm an alpha," he said.

The words tasted like victory.

Atsumu was behind him now, hovering in the doorway, his omega instincts warring with his need for closeness. He reached out a trembling hand, hesitated, then pressed his palm against Osamu's back.

"You're an alpha," Atsumu repeated, like saying it aloud would make it real.

"I can protect ya now." Osamu turned, caught his brother's wrist, held it firmly. "For real. Not just—standing there, telling people to leave. I can make them leave."

Atsumu's eyes shimmered. "Ya always protected me."

"Not enough." The words came out rough, almost angry. "I was a beta. I couldn't—I didn't have the presence. The authority. Alphas listen to betas about as much as they listen to omegas." He squeezed Atsumu's wrist. "But they'll listen to me now."

"Samu—"

"I mean it." Osamu's alpha voice slipped out, resonant and commanding. He pulled it back immediately, watching Atsumu's omega ears perk up in response. "Sorry. Still figuring this out."

"It's okay." Atsumu's voice was soft. Vulnerable. Trusting. "More than okay."

They stood there for a long moment. Twins. Same blood. Same face. But different now. The dynamic had shifted, settled into something new.

Osamu pulled his brother into a hug. His arms felt right wrapped around Atsumu's trembling frame. Protective. Possessive. His to guard. His to keep safe.

"From now on," he murmured into Atsumu's hair, "ya wear whatever ya want. Bikinis. Crop tops. Nothing at all. And if anyone touches ya, they answer to me."

Atsumu laughed wetly against his shoulder. "That's real creepy, Samu."

"I know." Osamu's smile was sharp. "That's the point."

---

The next morning, Osamu woke before sunrise.

The alpha instincts were already settling in, reshaping his worldview with every passing hour. He noticed things he'd never noticed before. The way Atsumu's scent changed in sleep—softer, more trusting. The way the hotel room felt defenseless before he woke. The way his own body hummed with a power he'd spent twenty years thinking he'd never have.

He'd been wrong.

So wrong.

The doctors told their parents he was a beta. Standard tests, standard results, standard disappointment. He'd accepted it. Internalized it. Told himself he didn't need the strength of an alpha, the instincts, the right to protect that came with being one.

But biology had its own timeline. And sometimes, it took a breaking point to unlock what was always there.

Atsumu stirred in the other bed. His omega ears twitched, catching Osamu's scent even in sleep. A soft whine escaped his throat—subconscious, instinctual.

"It's okay," Osamu said quietly. "I'm here."

Atsumu's eyes fluttered open. For a second, he looked disoriented. Then his gaze landed on Osamu, and something in his expression relaxed.

" 'Mornin'," he mumbled.

" 'Mornin'."

They didn't talk about it. Not yet. But the silence was different now. Fuller. Safer.

When Atsumu finally got up, he walked to the bathroom and emerged twenty minutes later in a different bikini. Bright red. Daring. A statement.

"How do I look?" he asked, and his voice held none of the tremble from yesterday.

Osamu looked at him. Looked at the way his brother held himself, shoulders back, chin up. Looked at the scars of yesterday's battle written in the tension of his jaw, the defiance in his eyes.

"You look like my twin," Osamu said simply. "And nobody's gonna touch ya."

Atsumu's smile was small. Fragile. But real.

"Promise?"

"Alpha's honor."

It wasn't a joke. Neither treated it like one.

They went back to the beach that day. Same spot. Same sun. Same swarm of eyes.

But this time, when a man approached, Osamu didn't just stand up. He moved. His alpha presence rolled out ahead of him like a tide, and the man's steps faltered before Osamu even spoke.

"She's not interested."

"Brother," Atsumu corrected. "I'm his brother."

"Right." Osamu's voice dropped, rumbling with an authority that hadn't been there yesterday. "And if ya touch him, I'll break your hands."

The man left without a word.

Atsumu watched him go, then turned to his brother with a look that was equal parts relief and wonder.

"Ya really changed," he said.

Osamu sat down. Stretched his legs out. Let the sun warm his new alpha skin.

"Yeah," he agreed. "I really did."

For the first time in years, the beach felt like it belonged to them.

And for the first time in his life, Osamu felt like he could finally do what he'd always been meant to do.

Protect.

---

Later that night, when the sun had set and the stars had crawled out to watch, Atsumu curled up on Osamu's bed instead of his own. His omega tail was wrapped around his brother's wrist, a casual gesture of trust that spoke louder than words.

"Does it hurt?" he asked quietly.

"Does what hurt?"

"Changing. So suddenly."

Osamu considered the question. His body still ached in places he didn't have words for. His mind was louder, sharper, filled with new instincts that warred with his old self. But the pain—the real pain—was nothing compared to the relief.

"No," he said. "It feels like coming home."

Atsumu's fingers found his. Squeezed.

"Good," he whispered. "Ya deserve to feel at home."

Osamu didn't cry. Alphas weren't supposed to cry. But his chest tightened, his throat burned, and he held his brother's hand until they both fell asleep.

The beach didn't matter. The men didn't matter. The groping and staring and objectifying didn't matter.

What mattered was this.

Two twins. One body between them. A bond that had survived second genders and suppressants and summer days that tried to break them.

And an alpha who would burn the world down before letting anyone touch what was his.
