Tide Turns

The waves rolled in slow and lazy, gentle enough to almost put you to sleep. Sand warm under Osamu's feet, a beach bag the size of a small human slung over one shoulder, a folded towel under his arm. Behind him, the soft shuffle of Atsumu's footsteps—slower than usual, weighted with the kind of tired that sleep alone can't fix.

"Samu, wait up." That familiar whine, but missing its usual edge.

Osamu stopped, turned. Atsumu stood a few paces back, sandals dangling from one hand, squinting against the sun. Red swim trunks hugging his hips, a simple bikini top—practical, comfortable. It made something in Osamu's chest ache. They'd bought those suits three years ago for a team beach trip. Back then Atsumu had been all sharp angles and sharper tongue, setting off fireworks in sets and arguments alike.

Now he looked softer. Rounded in the places life had changed him. A thin scar traced his lower belly, just above the waistband—reminder of the emergency C-section that left Osamu pacing a hospital hallway for seven agonizing hours, biting through his lower lip so hard he tasted blood.

"The bag's heavy," Atsumu said, catching up. "Carry it better."

"It's heavy 'cause you packed like we're stayin' a week."

"Baby needs options. What if he spits up on everything?"

Osamu snorted. "He spit up on everything in the diaper bag. That's what the extra onesies are for."

Atsumu waved a hand, no real heat behind it. He looked around—secluded beach, jagged rocks at either end, far from tourist spots Osamu had carefully avoided when planning this trip. Water clear and pale blue, almost turquoise where the sun hit. A few seabirds circling. Alone.

His shoulders dropped.

Osamu saw it. He saw everything these days—the way Atsumu held his breath when the baby cried, the way he'd stare at the bassinet for minutes, the way his hand would drift to his stomach and find nothing there, his face flickering with something unnameable.

"Found a good spot." Osamu nodded toward a wide patch of sand near a cluster of smooth rocks. "Shade in the afternoon. Easy water access."

Atsumu followed without arguing. That alone told Osamu how tired he really was.

They spread the blanket—big, thick enough to sleep on—and anchored the corners with towels and the cooler. Atsumu sank down almost immediately, folding his legs beneath him and letting out a long, slow breath. Soft, almost a sigh. Something in Osamu's chest loosened.

"You good?" He settled beside him.

"Mhm." Atsumu's eyes were already drooping. Sun caught the gold flecks in his hazel irises, made them look like warm honey. "This was a good idea, Samu. Really."

"'Course it was. I have 'em sometimes."

Atsumu laughed, tired and breathy. "Don't let it go to your head."

Comfortable silence. Osamu pulled out his phone, scrolled through recipe ideas while keeping one eye on his twin. Atsumu had stretched out on his back, arms pillowed behind his head, face tilted toward the sun like a cat soaking up warmth. Breathing evened out within minutes.

Osamu watched the rise and fall of his chest. The red fabric of the bikini top stretching across his ribcage, the slight swell of his breasts—fuller now than before pregnancy. A biological reality that had made Atsumu complain loudly during the first few weeks of lactation.

"They're heavy, Samu. And they leak. How's that fair? I didn't sign up for this." "You kinda did, though." "Don't be smart with me."

Osamu smiled at the memory. Scrolled past miso-glazed cod, stopped on creamy mushroom risotto. Atsumu loved risotto. Maybe he'd make it for dinner tonight, with grilled asparagus and—

The movement caught his eye.

At first his brain supplied innocent explanations: sweat, condensation from the cooler, a splash of ocean water. But the blanket was dry. The cooler was closed. And Atsumu was still fast asleep, face peaceful, chest rising and falling slow and steady.

Two small, dark circles had formed on the red fabric. They grew slowly, spreading outward from the center of each cup, staining the material a deeper shade.

Osamu's face went hot.

He looked away immediately, pulse jumping in his throat. This was normal. Biological. Natural. He knew that. He'd read the parenting books, attended the classes, sat through the hospital's post-natal care seminar even though he'd been running on four hours of sleep and too much vending machine coffee. He knew about lactation. Engorgement. He knew Atsumu had been expressing milk at home, storing it in bottles in the fridge, feeding their son with a patience that made something in Osamu's chest ache with fierce, protective love.

Knowing all that didn't stop the blush from creeping up his neck and burning in his ears.

He cleared his throat. "Atsumu."

No response.

"Atsumu." Louder. He reached out and touched his twin's shoulder, gave a gentle shake. "Hey. Wake up."

Atsumu stirred, made a small sound of protest. Eyes fluttered open, unfocused. "Mm?"

"Uh." Osamu's voice cracked. "You're, uh. Your—" He gestured vaguely at Atsumu's chest, unable to form words.

Atsumu blinked. Then looked down.

Understanding dawned slowly. His eyes widened just a fraction, a faint blush coloring his own cheeks. But instead of floundering like Osamu, red-faced and tongue-tied, Atsumu just sighed. A small, fond smile tugged at the corner of his lips.

"Oh," he said, as if Osamu had told him about a change in the weather. "Right. Forgot to express before we left."

"I can—" Osamu started, already half-rising. "I can go wait by the rocks or somethin'. Give you privacy."

"Sit down, Samu."

"But—"

"Sit." Atsumu patted the blanket beside him. "It's fine. You're gonna need to get used to this anyway. Baby's not gonna stop eatin' just 'cause we're at the beach."

Osamu sat. He kept his eyes firmly on the horizon, on the distant line where ocean met sky, on anything except his twin. He could hear movement—rustle of fabric, click of a latch, soft sound of Atsumu opening the diaper bag.

"Can you hand me the bottle? The clean one."

Osamu fumbled blindly, his hand finding the plastic bottle and passing it over. His fingers brushed Atsumu's, and he jerked back like he'd been burned.

Atsumu laughed. Gentle, teasing, but not mean. "You're cute when you're flustered."

"I'm not flustered."

"Sunburn," Osamu said before Atsumu could, deadpan.

"It's been fifteen minutes."

Osamu pressed his lips together and said nothing. Stared at the ocean with intense focus, counting waves as they broke against the shore. One. Two. Three. Let the rhythm anchor him.

Beside him, Atsumu worked quietly, efficiently. Osamu risked a glance—just a quick one—and saw him holding the bottle to his chest, expression focused but relaxed, the same look he got when perfecting a serve. No shame in his posture, no awkwardness. Just a man doing what needed to be done.

Warmth spread through Osamu's chest.

"I forget you're a mom sometimes," he said, the words slipping out before he could stop them.

Atsumu's hands paused. He looked up, eyebrows raised. "I'm literally nursing in front of you."

"No, I mean—" Osamu rubbed the back of his neck. "I still see you as my bratty twin who steals my rice balls and complains about practice. The whole 'parent' thing doesn't compute yet."

Atsumu's expression softened. He resumed his task, but his voice was quieter. "Yeah. I get it. Sometimes I look in the mirror and don't recognize myself." He paused. "In a good way, though. Mostly."

"Mostly?"

"Stretch marks are a bitch. And my hips hurt all the time." Atsumu grimaced. "But I see him, and I think—I made that. Me and you. He's got your stupid hair and my attitude, and I can't even be mad about it."

"Hey, my hair's not stupid."

"It's got a mind of its own."

"Your entire personality's got a mind of its own. Pot meet kettle."

Atsumu stuck out his tongue. Osamu threw a handful of sand at him. It landed in his hair, and Atsumu squawked, nearly dropping the half-full bottle.

"Samu! I'm tryin' to do somethin' important!"

"Sorry, sorry." Osamu was grinning now, tension bleeding out of his shoulders. "My bad."

"You're insufferable."

"Learned from the best."

The bottle was full. Atsumu capped it, wiped the rim with a cloth, and held it up. Pearly white milk caught the sunlight, warm and luminous. "There. Crisis averted."

Osamu let out a breath. "You done?"

"Yeah. Gonna change into a dry top in a minute, but—" Atsumu held the bottle out to him. "Here. Put this in the cooler."

Osamu took it carefully. The glass was warm, heated by Atsumu's body. He held it a moment longer than necessary, feeling that warmth seep into his palm, before tucking it into the cooler next to water bottles and juice packs.

When he turned back, Atsumu was shrugging off the damp bikini top, reaching into the bag for a replacement. Osamu's face went hot again, and he pointedly turned around, busying himself with rearranging the cooler.

"You can look, Samu. It's nothin' you haven't seen before."

"Things are different now."

"So? We're still us."

Osamu listened to the rustle of fabric, the snap of a clasp. He waited until he heard "Okay, all set" before turning.

Atsumu had changed into a plain black tank top, loose and comfortable. He sat cross-legged on the blanket, hair ruffled by the ocean breeze, looking more relaxed than Osamu had seen him in weeks. The shadows under his eyes were still there, but lighter now, less pronounced.

"Feel better?" Osamu asked, settling back down.

"Yeah. Sore, but better." Atsumu stretched his arms above his head, arching his back like a cat. A soft groan escaped. "I needed this. Quiet. Sun. No cryin'."

"He's not that bad."

"He's a newborn, Samu. They're all that bad." Atsumu dropped his arms, leaned back on his elbows. "But he's worth it. Even when he wakes me up at 3 AM."

Comfortable silence. Waves kept their endless rhythm. A gull cried overhead, distant. Osamu lay back on the blanket, staring up at the impossibly blue sky.

"We should do this more often," he said. "Get away. Even if it's just for a few hours."

"Can we afford the time?"

"We'll make the time." Osamu turned his head to look at his twin. "You're killin' yourself, 'Tsumu. I see it. You don't sleep, you barely eat, and you've got that look in your eyes like you're waitin' for the other shoe to drop."

Atsumu was quiet for a long moment. When he spoke, his voice was small. "I almost died, Samu."

"I know."

"The doctors said—" He stopped. Swallowed. "They said if we'd waited another ten minutes, the outcome would've been different. Ten minutes. That's nothin'. That's a trip to the convenience store. That's a short commercial break."

Osamu's chest tightened. He sat up, reached out, gripped Atsumu's hand. His twin's fingers were cold despite the heat, trembling slightly.

"I think about it all the time," Atsumu continued, voice cracking. "I hold him at night, and I think—I almost didn't get to meet him. I almost didn't get to see what his face looks like when he smiles. I almost—"

He broke off, eyes bright.

Osamu pulled him into a hug. Awkward angle, their bodies not quite fitting together like when they were kids. But Atsumu melted into it, burying his face in Osamu's shoulder, breath coming in short, shuddering gasps.

"I got you," Osamu murmured, rubbing his back in slow, steady circles. "You're here. You're fine. And I'm not goin' anywhere."

"You better not."

"Wouldn't dream of it."

They stayed like that a long time, wrapped in each other, the ocean a constant presence at their backs. Eventually Atsumu pulled away, wiped his eyes with the back of his hand, let out a shaky laugh.

"Sorry. Didn't mean to get all emotional."

"Don't apologize."

"I'm supposed to be relaxin'. Not fallin' apart."

"You're allowed to fall apart sometimes." Osamu squeezed his shoulder. "That's what I'm here for. To put you back together."

Atsumu sniffled. "When'd you get so good at this?"

"Always been good at it. You just never notice 'cause you're too busy bein' loud."

"Prick."

"Jerk."

Fragile grin, but genuine.

The afternoon wore on. They ate the onigiri Osamu had packed—salmon and pickled plum, Atsumu's favorites—and drank cold tea. Atsumu took a short nap, head resting on Osamu's thigh, and Osamu let him sleep, running fingers through his twin's hair in a slow, soothing rhythm.

The sun climbed higher, then began its slow descent toward the horizon. Shadows lengthened. Temperature dropped. A cool breeze replaced the afternoon heat.

Around four, Osamu realized he was thirsty.

Really thirsty. He'd been so busy making sure Atsumu ate and drank enough, he'd forgotten himself. Dry mouth, scratchy throat. He reached for the cooler, popped it open, and found—

Empty. Or rather, empty of anything drinkable. Remains of lunch, half a pack of baby wipes, and the bottle of Atsumu's expressed milk.

Osamu stared at the bottle.

Options ran through his head. Walk to the convenience store—twenty minutes, maybe twenty-five. Tough it out until they left, another hour or two. Ask Atsumu to check the diaper bag for a missed water bottle.

What he was not going to do was drink his twin's breast milk.

Except.

Except the thought had already crossed his mind, and now it was lodged there like a stubborn splinter. He was thirsty. The milk was right there. Fresh, stored properly, safe. People drank breast milk all the time. Nutritious. Hydrating.

That's weird, right? That's definitely weird.

"Everything okay?" Atsumu's voice cut through. He'd woken up, was sitting up and stretching, eyes still heavy-lidded.

"Yeah. Fine." Osamu closed the cooler. "Just thirsty."

"There's water in my bag."

"Checked. It's empty."

Atsumu frowned. "There was a whole bottle in there this mornin'."

"You drank it on the way here."

"Oh." He thought for a moment. "Well, there's the milk. It's still good. You could have that."

Osamu's face went red. "What?"

"The milk. In the cooler. You could drink it." Atsumu said it so casually, like offering a carton of orange juice. "It's just milk, Samu. Nothin' weird about it."

"Nothin' weird—" Osamu sputtered. "It's your—it's—"

"Breast milk. Yeah. I know what it is." Atsumu's lips twitched. "I promise it won't bite."

"That's not the point."

"Then what's the point?"

Osamu opened his mouth, closed it, opened it again. He realized, with a sinking feeling, he didn't actually have a good reason for his reluctance. It was just milk. Came from Atsumu, yeah, but still just milk. A biological substance, perfectly safe, designed to sustain life.

But it was also intimate. Personal. Something shared between mother and child, not between two grown siblings on a beach.

"It's weird," he finally said, lamely.

Atsumu shrugged. "Only if you make it weird. I've had worse. Remember that time you dared me to drink that expired smoothie?"

"That was different."

"How?"

"It was a smoothie."

"And this is milk. Both liquids. Both consumable. What's the difference?"

Osamu couldn't come up with an answer. Just sat there, fuming, while Atsumu watched with that infuriatingly smug expression.

"Just try it," Atsumu said. "If you don't like it, I'll walk to the store and get you some water. Deal?"

"You're not gonna let this go, are you?"

"Nope."

Osamu sighed. Opened the cooler, pulled out the bottle, held it up to the light. Pale and creamy, slightly translucent at the edges. Looked... normal. He unscrewed the cap and sniffed it. Faintly sweet, like warm cereal.

"Just drink it, Samu."

"Stop rushin' me."

"At this rate, the sun's gonna set before you take a sip."

Osamu shot him a glare, but Atsumu only smiled. He brought the bottle to his lips, closed his eyes, and took a small, hesitant sip.

The milk was warm—warmer than he'd expected, probably from sitting in the sun despite the cooler's insulation. Thin, not as thick as cow's milk. And sweet. Subtle and pleasant. Like melted ice cream, or the last sip of a milkshake. Good.

He took another sip. Then another.

Atsumu was watching with raised eyebrows. "Well?"

Osamu lowered the bottle. "It's sweet."

"Sweet?"

"Yeah. Like—" He licked his lips. "Like rice milk. Or almond milk. But sweeter."

Atsumu looked surprised. "Really? I've never actually tasted it."

"You made it and you've never tasted it?"

"I'm not a weirdo, Samu."

"You literally just watched me drink it."

"To prove a point."

Osamu took another drink. It was growing on him, he had to admit. Refreshing in a way he hadn't expected, settling in his stomach with a pleasant warmth. He finished half the bottle before setting it down.

"Good?" Atsumu asked.

"Yeah. Actually." Osamu wiped his mouth with the back of his hand. "It's good."

Atsumu laughed, bright and genuine. "I'm tellin' everyone about this."

"Don't you dare."

"Samu Miya, professional volleyball player, caught drinkin' his twin's breast milk on a secluded beach. Can you imagine the headlines?"

"I will drown you."

"You wouldn't. Who'd cook your meals?"

"Takeout exists."

"But it doesn't taste like my cookin'."

Osamu couldn't argue with that. He capped the bottle and put it back in the cooler, cheeks still flushed but heart light. The tension from earlier had dissipated, replaced by a familiar ease—the kind that only came from years of shared history and unconditional trust.

Atsumu leaned over and bumped his shoulder. "Thanks, Samu."

"For what?"

"For bringin' me here. For—" He gestured vaguely. "Everythin'. I know I'm a handful."

"You're more than a handful. You're a whole armful."

"Shut up."

"Make me."

Atsumu shoved him, and Osamu shoved back, and they ended up wrestling on the blanket, laughing like teenagers again. Sand everywhere—hair, clothes, mouths. By the time they broke apart, they were both out of breath and grinning like idiots.

"I'm gonna cook you somethin' special tonight," Osamu said, once he'd caught his breath. "That risotto you like. With the mushrooms."

"With the mushrooms?"

"And the asparagus. And maybe some grilled fish, if the store has any good cuts."

Atsumu's eyes softened. "You don't have to do that."

"I want to."

"Then okay." Atsumu smiled, small and genuine. "I'd like that."

They packed up as the sun began its final descent, painting the sky in shades of orange and pink and gold. Osamu carried the heavy bag, as he always did. Atsumu walked beside him, a lightness in his step that hadn't been there when they arrived.

The car was a short walk away. Osamu loaded the trunk while Atsumu buckled into the passenger seat, already pulling out his phone
