Zoro could tell his heat was coming. It felt like an itch under his skin that he couldn't scratch, and he knew he had about a week before it hit fully. Hopefully that was enough time for the ship to reach a populated island with an Alpha Bar.
His secondary gender didn't bother him one way or the other. The heats were a pain because he'd rather be training, but he enjoyed the sex. Chopper had offered to get him heat aids when the little doctor first joined the crew – a conversation Zoro wanted to forget had ever happened. They didn't really work for him anyway. He'd rather go to an Alpha Bar like he'd been doing since he first presented. There he could lock himself in an omega box, get laid, and not worry about it.
And if he was lucky–
He shut that thought down fast. It didn't happen often, and it hurt to think about.
Lusca Island was large enough to have a proper port, with stone docks, warehouses, repair yards, and several streets climbing inland from the waterfront. Fishing boats crowded the harbor beside merchant ships and smaller passenger vessels, while taverns, boarding houses, shops, and bathhouses filled the blocks nearest the docks. Beyond the town, low green hills rose toward the center of the island, broken by farms, scattered houses, and a few stretches of forest.
Zoro was already sweating when he stepped onto the dock. His heat had started that morning, and the wetness in his briefs had grown uncomfortable. All his clothes felt uncomfortable against his skin. He was hot, his mouth dry, and the ache to be filled had settled deep inside him. His dick was stiff against the front of his briefs, every step making it rub against the fabric and worsening the need. He knew his scent was pouring off him by now, drawing alphas' attention and urging them to breed him.
He just needed to make it to the Alpha Bar. Nami had given him money from the funds set aside for him. It was the one thing he didn’t have to repay or pay a fee on – even Nami wasn’t greedy enough to charge him for biology. She kept money aside for ruts, too, and made sure Chopper had plenty for suppressants and pregnancy prevention. Zoro had the anti-pregnancy shot, but he didn’t bother with suppressants unless the timing was bad. He was what he was, and he dealt with it.
Zoro had trained himself not to let his mind go fuzzy until he was safely inside an omega box. He’d ended up in too many alleys, getting fucked into the dirt. Once, when he was younger, he’d somehow wandered into another village on the opposite side of his home island and let the wrong alpha take him home. He’d ended up locked in a breeding cage for nearly a year. He got lucky – no pups came of it, and eventually they let him go because of that. It had set his training back badly, and he’d had to work three times as hard to get back to where he’d been.
Zoro left the docks and followed the busiest street into town, passing taverns, chandlers, food stalls, and narrow shops packed between weathered buildings. He kept an eye out for the familiar Alpha Bar mark while trying not to pay attention to the alphas who turned their heads as he passed. By the third intersection, he was starting to suspect he’d gone the wrong way.
But then he spotted what he’d been looking for down one of the side streets. He quickened his pace, swords bumping against his hip. The bar’s exterior looked no different from the buildings around it, but when Zoro circled around back and saw the omega entrance, relief loosened something in his chest.
A hard knock brought an attendant, who peered through the viewing slit and sniffed the air before releasing a series of bolts and bars. The door opened, and the beta bouncer stepped aside to let Zoro through.
A plain hallway stretched ahead, doors lining either side and a communal bath at the far end. Each room had a pay slot beside the door and a light overhead. Red meant occupied.
While the beta shut and secured the entrance behind him, Zoro headed straight for the bath. He stripped at one of the provided lockers, keeping his katanas close, and held onto the key. After using the toilet, he took a quick shower – his last for a while – then collected his swords and beli and returned to the hall with a towel wrapped around his waist.
He fed beli into the pay slot of an empty room. A moment later, the lock released.
Zoro stepped inside, shut the door, and turned the secondary bolt, activating the red occupancy light outside. The outer room was small, holding only a cot, a water tap, and a toilet. Alpha Bars weren’t meant for nesting.
A cup sat beside the sink for whenever he needed a drink. Zoro dropped the towel onto the cot and opened the second door.
The omega box was smaller still, designed to be accessed from outside rather than moved around in. Zoro could stand upright, but he could easily touch either wall. A black padded breeding bench occupied most of the floor. Beneath it sat an oxygen canister with a fresh hose attached. The box smelled strongly of cleanser and neutralizer, though his own scent was already beginning to overwhelm both.
Drop panels were built into the walls at the head and foot of the bench, each controlled from inside the box. Thick padding circled the openings – one positioned for his ass, the other for his mouth. Beside them, long gloves extended through the wall so an alpha could grip his hips or hair without either of them seeing or directly touching the other.
The whole arrangement existed for anonymity. Whoever was outside never had to know who was inside.
Zoro leaned his katanas into the corner and pressed a hand against his hard dick. He was so horny it hurt. Slick already coated his thighs, his body demanding a knot immediately.
He picked up the oxygen hose and threaded it into place with practiced ease. Plenty of omegas ignored the mouth access, but Zoro wanted knots wherever he could get them, and the hose meant he could still breathe.
Reaching beneath the bench, he switched on the air and checked the flow before settling chest-down onto the padding. His erection fit snugly into the pouch built into the bench, there to absorb his spend whenever he came.
He shifted until his knees rested comfortably beneath him, feet braced against the rear wall and his ass positioned against the panel. His arms could either rest across the support beneath his chin or extend toward the braces near the floor. Beside the left brace sat the switch controlling both access panels. Once he flipped it, the openings would drop and lights would activate in the alpha booths outside.
There were two of those booths, one at either end of the box, each enclosed for privacy. Alphas paid nothing to use them. The entire purpose of an omega box was to keep an omega in heat serviced as often as possible, and charging the alphas would only interfere with that.
Zoro liked omega boxes for three reasons – sex, anonymity, and safety. He didn’t care who fucked him as long as somebody did, and once he was inside the box, he didn’t have to stay alert or watch his back. He could finally stop controlling himself and simply be an omega in heat.
And if Luffy started trouble somewhere on the island while Zoro was locked away, Chopper would come get him, as previously arranged. It had only happened once. Zoro had been so pissed about the interruption that the resulting fights hadn’t lasted long.
He checked once more that he was comfortable and that his katanas remained visible from the corner of his eye. Then he licked his lips, flipped the switch, and pressed himself against the padded openings as anticipation surged through him.
A door opened. The moment Zoro caught the alpha's scent, his mind clouded with raw need. A few seconds later, gloved hands cradled his head as a rigid cock pressed against his lips. He parted them eagerly, welcoming the alpha's deep thrust. The salty taste of skin, the satisfying stretch of his lips, and the rough grip sent waves of desire coursing through him.
Within moments, another pair of gloved hands gripped his hips. A thick alpha cock breached his slick entrance, filling him completely. Trapped between two dominant alphas, Zoro finally surrendered his control, letting the heat's haze consume him entirely.
The air was thick with the musky scents of sex and alpha. The rhythmic slap of hips against his ass and the obscene smack of balls against his chin drove him into mindless lust. His body surrendered to the powerful thrusts from behind, forcing his erection to rub maddeningly against the fabric of the pouch. Every nerve ending felt like a live wire, sparking with desperate need. He craved it, needed more, wanted everything they could give him.
The first knot always sent him spiraling into climax. The alpha's cock in his mouth swelled at the base, and with one final, brutal thrust, the knot popped past Zoro's overstretched lips. His body convulsed as he came, spilling into the pouch just as hot alpha seed pumped down his throat. The knot locked him in place, transforming his mouth into a cocksleeve, his throat visibly bulging around the alpha's deep penetration. Knots lasted as long as they lasted, and the small breathing hose was the only reason Zoro could still draw air.
The alpha behind him reached his own climax, his knot swelling and catching in Zoro's hole as he pumped him full of release. Zoro floated between knots, his mind lost in that hazy bliss of an omega satisfying alphas.
When the knots finally went down and the alphas left, Zoro took a moment to breathe before new ones arrived, filling the space with their scents, their cocks, and their knots. Zoro wanted nothing more than to be bred by them.
The slick never stopped flowing, keeping him sopping wet as his hole was used again and again. Semen joined the slick, sliding down his thighs. Drool coated his chin, his jaw ached with constant use, and sweat dripped along his temples and down his spine. The heavy scent of omega heat filled the confined space, the air thick and hot.
He was fucked and knotted, then fucked again. Gloved fingers dug into his hips, leaving bruises that would bloom later. Gloved hands ripped at his hair as he was used, and used hard. One alpha grabbed the back of Zoro's neck, scruffing him, and his entire body went limp, making him feel that much more at the mercy of the alphas' pleasure.
He took and took, riding that wave of bliss that made him feel everything and nothing at once. He reached the point where if he wasn't filled, he dropped hard, whimpering and wordlessly begging for cock. He came again and again, spilling inside the pouch until his orgasms produced nothing but air.
Still, the alphas came. Still, his heat held him captive. Still, he desperately wanted knots. His jaw dislocated after one particularly forceful knot, the pain sublimating into intense pleasure. It allowed him to take knots even easier in his mouth.
He didn't know how much time passed. His stomach was pumped full of spend, and his hole leaked steadily with alpha release. He felt numb in the best way possible. The two alphas taking their fill of him punched hard and deep, fucking him as they pleased, and he could only think of wanting more.
A new knot swelled in his ass, stretching him impossibly wide as the alpha behind him snarled his completion. Zoro's body, slick with sweat and fluids, trembled with another dry orgasm. The alpha in his mouth followed suit, his knot pulsing as he flooded Zoro's throat. Trapped and plugged at both ends, Zoro drifted in a sea of sensation, the pain and pleasure blurring into a single, overwhelming wave of fulfillment. He was a vessel, a sheath, a hole to be used, and the thought brought him a profound, bone-deep peace.
When they finally pulled away, their knots receding, Zoro felt an immediate, hollow ache. The emptiness was a physical pain, a void that screamed to be filled. He didn't have to wait long. Another scent, sharp and dominant, cut through the haze, and a new alpha was there, grabbing him with rough gloved hands. The brief respite was over; his heat demanded more. His body, bruised and aching, responded with a fresh gush of slick, ready for the next round, desperate to be taken and claimed all over again.
Sweat bathed his body and soaked into the breeding bench. His hair was plastered to his head wherever it hadn’t been yanked and twisted. Streaks of pleasured tears marked his cheeks, and his cock ached from continual release.
Alpha Bars never closed, and each shift change brought more patrons through to make use of the omega box. Zoro hadn’t moved, and he’d wet the pouch more than once. His muscles and joints would protest once the heat finally released him, but for now he didn’t care. Nothing mattered except being bred by alphas.
Then the scent changed. One alpha left, and another stepped into the booth. Acrid. Familiar. Fervently wanted.
A high-pitched sound tore from Zoro's throat, an omega's desperate call for a mate. His chin lifted instinctively, trying to bare his throat, but the opening prevented him. He panted and keened, ignoring the cock pumping into his ass, his entire being focused on the new alpha before him. Bare fingers touched his lips – a violation of the rules – before pressing into his mouth. With his jaw dislocated, he couldn't close around them, so he licked greedily instead, tasting the familiar tang of pepper and ash.
The alpha made a quiet sound of approval, and Zoro melted into a purr. The fingers withdrew, replaced by the tip of a cock. Zoro tongued around the swollen head, licking across the slit, showing reverence to this alpha, hoping that if he was good enough, this one would finally mate him. Fingers brushed his cheek before the alpha pressed fully inside. Zoro's mouth filled with cock, the head sliding easily down his throat. He swallowed around it, a difficult motion after being used for so long, but he did it, knowing it would please this alpha. The alpha behind him knotted and fell still, allowing Zoro to concentrate completely on the one in his mouth.
The alpha began to pump his hips, slowly at first, dragging his cock to the very edge of Zoro's bruised, swollen lips before sliding back inside. Zoro pressed his forehead harder against the padding, trying to get closer, longing to touch skin. He felt wiry curls scratch against his upper lip with each slow push down his throat. He breathed deep when he could, drinking in this alpha's scent, knowing it as well as he knew his own. He wanted to bathe in it, feel it rubbed all over him, claiming him the way he longed to be claimed.
The alpha's pace quickened, pumping into Zoro's mouth, his pelvis bumping against Zoro's face. Zoro took what was given, trying to use his tongue, wanting to be the best omega. The thick length punched his throat, and he drooled around the shaft that stretched his lips thin. Every molecule of him wanted this alpha, to have this alpha fill him with his seed.
The knot formed, and Zoro purred with anticipation. With a final breach of his lips, the knot locked and the alpha stilled. Release spilled down Zoro's throat. He breathed through the hose and sank into that sated place of pleasing a potential mate. Fingertips brushed along his stretched upper lip, calluses catching where they'd split. Zoro wanted nothing more than to feel those fingers touching other parts of him, to feel those hands holding him, to feel a scruff on his neck and a bite on his glands.
The knot behind him eased, leaving him briefly empty before another cock slid into him. He barely noticed. He wanted the one in his mouth to stay forever.
But it didn’t. The alpha’s knot went down, and Zoro keened softly when he withdrew. A gentle caress against his cheek was the last touch he got before the scent he longed for disappeared.
Zoro pawed at the wall and cried out wordlessly, his omega heart breaking. He’d been rejected again.
Another alpha took the empty place, pushing roughly into his mouth and setting a hard rhythm. Tears kept slipping down Zoro’s cheeks until the next knot formed.
Then he let himself sink back into the blissed haze of being bred.
When his heat finally ended, Zoro flipped the switches to close the access panels and dragged himself stiffly to his feet. He moved his katanas within reach, collapsed onto the cot in the outer room, and slept hard.
He woke groggy and disoriented, taking a few moments to remember where he was. Then he snapped his jaw back into place, yawned, and slowly stretched until the worst of the aches eased.
He drank directly from the faucet, careful not to go too fast, then ducked his head beneath the cool water. He didn’t bother drying off. Instead, he wrapped the towel around his waist, unlocked the outer door, and headed back toward the communal bath with his katanas and locker key in hand.
After a shower and a long soak, Zoro dressed and left the bar. By the time he got back to the ship, Chopper would want to check him over, give him another anti-pregnancy shot just in case, and gently scold him for letting himself be used so roughly.
He found the ship after a few hours and a quiet walk through the woods. Evening was settling over the horizon. The harbor was still busy, lights coming on in windows and aboard boats as dockworkers finished unloading the last cargo of the day. Voices carried across the water from the taverns near the quay, mixed with the creak of ropes and the occasional call between ships. The Sunny’s rigging knocked as the ship bobbed gently in its mooring.
The ship was mostly quiet when he came aboard. Brook was playing his violin for Chopper and Robin, but Chopper immediately jumped up and hurried to Zoro’s side. “Zoro, you’re back. Is everything okay? Anything I need to know about right away?”
“No, I’m good,” Zoro said, allowing himself to be herded toward the infirmary. Robin nodded to him and Brook tipped his head as they passed. “How long was I gone?”
“Four days,” Chopper told him. “Still in your average range.”
Zoro’s heats came every few months and usually lasted somewhere between three and five days. Chopper had been tracking them since joining the crew, enough that the whole routine had become familiar by now.
They went in through the back entrance, which led directly into the infirmary, a compact room lined with cabinets, medical supplies, and a narrow examination bed. Zoro stripped and let himself be fussed over, got his shot and IV fluids, and watched Chopper break into a little dance when Zoro thanked him for taking care of him.
“I don’t need your thanks, asshole,” Chopper declared, wiggling giddily in place. “It’s my job!”
To Zoro, who had spent years taking care of himself afterward, it meant more than that.
Once he was unhooked from the IV, Zoro strapped his katanas back to his hip and took a breath before heading into the galley through the connecting door. “Cook. Food.”
Sanji stood at the sink on the kitchen side of the galley, warm air carrying the smell of cooked food and cigarette smoke through the room. A pile of dirty dishes waited beside him, while the breakfast bar separating the spaces already held a plate of food and a chilled bottle of sake.
“Did you shower? I don’t want your disgusting stench stinking up my galley,” Sanji said flatly.
“I’m clean,” Zoro said, irritation already creeping into his voice.
“Sure about that?”
Zoro’s gaze narrowed at the cruel jab. “Keep your shitty comments to yourself.”
Sanji met his glare through a haze of smoke. “Just making conversation.”
“No, you’re being a prick, just like you are every time I get back from a heat,” Zoro said, grabbing the sake. “Like I’m going to rub my gay germs on you.”
Sanji’s lips thinned around his cigarette. “I don’t care that you’re gay.”
Zoro gave a bitter laugh. “Yeah, but you care if anyone thinks you might be.”
Sanji didn’t answer, which was answer enough.
Zoro collected his plate and tucked the sake under his arm. “Great to know you haven’t changed.”
“Bring the plate back when you’re done.”
Zoro let the galley door slam behind him.
He stood for a moment at the top of the stairs, letting the salty sea air clear the acrid traces of pepper and ash from his nose.
Then he took his food up to the crow’s nest and pretended his heart didn’t ache.
