The Morning Run

The Sunday morning sun was weak, barely making it through the grime on the Miya kitchen windows. Osamu was on the genkan, untying his running shoes. Still sweating, legs humming from a good five-K. He grabbed a towel from the laundry room, wiped his face, and padded down the hall toward his twin’s room. House was silent except for the fridge humming.

He knocked. Three sharp raps. “Oi. Wake up, ya sluggard. It’s almost ten.”

No answer.

He counted to five, knocked again, harder. “Atsumu. I’m comin’ in.”

Still nothing. No grunt, no pillow thrown at the door. That was weird. Osamu’s jaw tightened. He twisted the knob and pushed.

The room was dark and messy. Blinds half-drawn, gray light slicing through a chaos of clothes, empty energy drink cans, tangled sheets. Smelled like sleep and deodorant. Osamu stepped in, let his eyes adjust.

There he was. Atsumu curled on his side, one arm under his pillow, the other on his stomach. Hair a disaster—blond strands sticking up everywhere, roots dark with sweat. Face slack, mouth slightly open. He was wearing black boxer briefs and a binder. The racerback kind, with compression panels. Flattened his chest into something more like a swimmer’s torso. Osamu had seen it a hundred times. It was just part of his brother now.

He looked away, out of habit, and cleared his throat. “Atsumu. Wake up.”

Atsumu stirred, groaned. Rolled onto his back, blinked, found Osamu. His eyes went wide, then narrowed. “What the hell, ’Samu? Get out. I’m sleepin’.”

“It’s almost ten. Mom left a note—she’s at the temple fair with Auntie ’til evenin’. Ya missed breakfast.” Osamu crossed his arms, leaned against the doorframe. “And ya left the milk out again. Had to pour it down the drain.”

Atsumu grunted, no apology. He sat up slowly, winced. His hand went to his lower back, pressing against the binder. Osamu noticed. Something off.

“Ya alright?” Osamu’s voice lost the teasing edge.

Atsumu’s head snapped up. His cheeks went deep pink. “Fine. Why wouldn’t I be fine?”

“Because you’re sittin’ like ya swallowed a cactus.”

“Shut up.” Atsumu swung his legs over the bed, stood up. Bare feet hit the floor. He grabbed a hoodie from a chair, pulled it on, didn’t bother zipping. The binder flattened his chest under the fabric. He wouldn’t meet Osamu’s eyes.

Osamu waited. He knew that look. That was Atsumu’s “I’m embarrassed but too proud to say it” look. Eighteen years in the same womb and then the same room—he knew every shade.

“I’m gonna run to the store,” Osamu said, neutral. “Need anything?”

Atsumu’s head shot up. “Store? Why?”

“We’re out of milk. I want onigiri rice for lunch. And I saw your breath this morning—you need mouthwash.”

Atsumu grumbled but didn’t deny it. He shuffled to his dresser, opened a drawer, pretended to look for something. Osamu watched his shoulders rise and fall with a deep breath.

“Actually…” Atsumu’s voice came out strangled. He cleared his throat. “Yeah. There is somethin’. But ya gotta promise not to—not to laugh. Or tell anyone.”

Osamu raised an eyebrow. “I’m not in the habit of tellin’ your secrets. Spit it out.”

Atsumu turned around. His face was the color of a ripe tomato. He was gripping the edge of the dresser like it was the only thing keeping him up. “Can ya… can ya get me some…” He trailed off, swallowed hard.

“Some what?”

“Lube.”

The word hung in the air like a soap bubble. Osamu blinked. Once. Twice.

“…Lube,” he repeated, deadpan.

Atsumu’s eyes were wild. “Don’t make me say it again! I need lube, okay? The kind they sell at the pharmacy. Not the cheap stuff. The—the good kind. For sensitive skin. And just—just get it! Please.”

Osamu’s brain stuttered. His brother asking for lube. That meant… what? Atsumu seeing someone? He hadn’t mentioned anyone. Not that Atsumu shared. But still, he was eighteen. He played volleyball like a demon, practiced until his fingers bled, spent free time eating junk and fighting over the remote. When did he have time for that?

Osamu’s own face got hot. He forced himself to stay calm. “Alright. I’ll get it. But why now? What happened?”

Atsumu’s hands flew to his face. “I don’t wanna say.”

“Too bad. I’m your brother. If you’re hurt, I need to know.”

A long, shuddering breath. Atsumu dropped his hands, looked defeated. “I was… experimentin’. By myself. And I guess I didn’t use enough… stuff. And now it’s all raw down there. Stings when I walk. And I can’t exactly ask Mom to buy me lube, can I? She’d have a heart attack.”

Osamu felt the tension drain. Relief flooded through him. Not a partner. Just Atsumu being an idiot. Classic Atsumu: jump in without prep, end up in pain.

“Ya rubbed yourself raw,” Osamu said flatly.

“Yes! Are ya happy? You got your confession. Now are ya gonna help me or just stand there lookin’ smug?”

Osamu snorted. “Fine.” He was trying not to laugh, but not in a mean way. “I’ll go. But next time, do some research first, genius. It’s not rocket science.”

Atsumu threw a sock at him. Osamu ducked, still chuckling, and jogged out.

The local grocery store was a five-minute jog from the house, on a corner where the residential street met a busier road. Clean and bright, fluorescent lights humming, polished floors. Osamu grabbed a basket and headed straight for the personal care aisle, trying to look casual.

Aisle was mercifully empty. He scanned the shelves: condoms, pregnancy tests, lubricants. Dizzying array of bottles and tubes. Never bought lube before. Had no idea what to look for. He picked up a small bottle—"Water-Based Lubricant, Unscented." Seemed safe. But Atsumu said "good kind." And for sensitive skin.

Osamu hesitated. Then he thought about Atsumu wincing when he sat up. Needed something gentle. Something that wouldn’t sting. His eyes fell on a shelf labeled "Feminine Care" at the end. Nestled between moisturizers and washes was a pink label: "Slippery Stuff — Gentle & Fragrance-Free, pH Balanced, Gynecology Recommended."

Looked like it was designed for internal use. For women. But Osamu figured it was the safest bet for sensitive mucous membranes. His face burned as he grabbed the bottle, shoved it into his basket, and walked quickly to the checkout.

The cashier was a bored teenager who barely glanced at him. Osamu paid with a crumpled bill, pocketed the lube in his jacket, and jogged back home with the bottle burning a hole in his pocket.

When he got back, Atsumu was sitting on his bed in a loose T-shirt and sweatpants. Hair still a mess, but he’d splashed water on his face. His eyes went straight to the jacket pocket.

Osamu closed the door behind him, pulled out the bottle, held it out without quite meeting Atsumu’s eyes. “Here. Got ya the fancy stuff. Supposed to be gentler.”

Atsumu took it, turned it over, read the label. Cheeks reddened again, but a small, grateful smile tugged at his mouth. “Thanks, ’Samu. I… appreciate it.”

“Don’t mention it. Ever. I mean it.”

“Yeah, yeah.” Atsumu set the bottle on his nightstand, then grimaced as he shifted. “I swear I didn’t think it’d be that bad. I just—I wanted to see what it was like. And now I can barely sit.”

Osamu sat down on the edge of the bed, a careful distance away. “What were ya even tryin’ to do?”

Atsumu’s face went from pink to red. He stared at his lap. “Ya know. Down there. With… toys. I ordered one online. A small one. And I thought I’d be fine without… you know. But it was too dry and now I think I tore something.”

Osamu let out a long breath. Ran a hand through his still-damp hair. “You’re an idiot.”

“I know.”

“But I get it. Ya wanna explore. That’s normal.” Osamu’s voice softened. “Just… be more careful next time, alright? Use lots of lube. And maybe start with your fingers. Or something smaller.”

Atsumu groaned. “Stop givin’ me advice. This is weird.”

“You’re the one who asked me to buy lube for you. You don’t get to complain about weird.”

Atsumu looked up at him then. His eyes were still glassy with embarrassment, but there was gratitude there too. A quiet, vulnerable thing that only Osamu ever got to see. “Ya didn’t have to get the expensive one. I would’ve taken anything.”

“Yeah, well. You deserve the good stuff.” Osamu reached out and ruffled Atsumu’s hair, messing it up even more. “Just don’t make a habit of this, okay? I’m not runnin’ to the store every time ya get curious.”

Atsumu swatted his hand away, but he was smiling. A real smile, not his usual cocky smirk. “Thanks, twin.”

“Don’t mention it. Seriously. If ya ever bring this up again, I’ll deny it.”

“Fine. But ya better not tell anyone I cried over a toy.”

“I won’t. But I will tease ya about it forever.”

Atsumu laughed, short and breathy. He picked up the bottle, read the label one more time, then tucked it into his nightstand drawer. “I’m gonna go take a shower. And use this. Not together. I mean, I’ll use it after. In private.”

“Gross. I didn’t need that mental image.”

“You’re the one who bought it.”

Osamu stood up, headed for the door. Paused with his hand on the knob. “Hey, Atsumu.”

“What?”

“Next time, don’t be afraid to ask for help. That’s what I’m here for. Even for weird stuff.”

Atsumu’s voice was soft. “I know. Thanks.”

Osamu opened the door, then looked back over his shoulder. “And for the record, ya better not need to replace the sheets again. Mom’s still mad about the ramen incident.”

Atsumu threw a pillow at him. Osamu caught it, laughing, and tossed it back. “I’m serious! Learn from your mistakes!”

He closed the door, grinning. The awkwardness had faded, replaced by something warm and steady. They were twins. They’d survived worse than a lube run. And on that quiet Sunday morning, Osamu knew Atsumu would be okay. Because he had a brother who always had his back. Even if it meant buying the most embarrassing thing on the shelf.

Osamu walked to the kitchen, grabbed a bottle of water, and sat down at the table. He heard the shower start running. Smiled to himself, shook his head, and started planning what onigiri fillings he’d use for lunch.

Some things never changed. And that was just fine.
