Work Text:
Luffy just barely manages to sneak into the office without his overbearing grandpa (the head manager of the office) or that one really boring bald man noticing him as he hauls in a stack of boxes filled with printer paper. Past a sea of gray cubicle walls, he spots a head of pink hair and rushes over after dropping off the supplies.
“Coby!”
The young man looks at him and nearly drops the technical equipment and drink in his hands. Luffy feels his cheeks getting sore from smiling a little too widely, but he can’t help it—Coby’s just too funny, especially when his face gets as pink as his hair and he fumbles about. Luffy makes deliveries to a lot of different offices, and for the longest time his grandpa’s was his least favorite to deliver to, even going so far as to leave packages outside on the front door until he was nearly fired for it (and his grandpa gave him a few knuckle sandwiches over). But a little less than two years ago, the old IT guy suddenly couldn’t make the day shift anymore, and in comes a short pudgy boy fresh out of college with the biggest, thickest glasses and the dorkiest haircut Luffy’s ever seen.
“Luffy, hey, hello, hi!” Coby says frantically, trying to juggle the computer equipment in his hands without spilling his protein concoction.
Coby straightens himself out as well, trying to stand as tall as Luffy. They’re about the same height, and now Coby is noticeably taller and bigger than he was two years ago (with a slightly less dorky haircut), muscles clearly defined under his business casual button-up and slacks. Luffy laughs, thinking about when Coby started chugging these weird not-exactly chocolate and not-exactly peanut butter protein shakes everyday not long after Luffy managed to easily fight off a thief trying to steal Coby’s bag one night. They’re no where near as tasty as a real chocolate milkshake, but they seem to be working for Coby, at least.
Nevertheless, regardless of size or hairstyle, Coby’s still Coby, and Luffy likes him much more than the old IT guy, so much so that now making deliveries to this office wasn’t so bad, even if there’s a chance of running into his crazy grandpa.
“Wanna get lunch together?”
“Yes!” Coby says, perking up at the invitation. He scrambles around his desk for his wallet and keys, still juggling his tech equipment in his other hand.
“Let’s go to”
“I thought I saw you come in!”
Luffy groans as the most boring old man alive walks towards the two—Coby's coworker, Cohen or Dolin or something. The dullest person alive who somehow tires even Luffy out just by talking.
“Have I shown you two my photography before?”
He flashes Luffy and Coby a few mundane photos and stops at blurry one of a full moon.
“Now this one’s interesting because the camera lens I used is actually different from the normal one I usually used, which is from my mother from the 80’s, and you know back in the 80’s…”
Luffy hears a clatter and sees Coby’s drink, equipment, keys, and wallet suddenly spilled over the ground as Coby takes a step back, gripping the edge of his table and shaking. Luffy frowns and picks up the mess of cables and knick-knacks, looking up at Coby with concern.
“Coby?”
“I… I have to go,” Coby says with a strained voice.
“But what about—”
The pink-haired IT tech runs off before he could get a response, not without accidentally knocking over a few tables and chairs. The commotion is enough for Garp to peek his head out of his office, looking in Coby’s direction. Luffy takes the opportunity to drop the items and skip off towards the alternate exit, because Coby’s probably just not feeling well and Luffy’s too hungry to deal with his crazy grandpa right now, since it’s well after 2:00pm and he hasn’t even eaten lunch yet. The boring guy probably says goodbye, but Luffy doesn’t notice or care.
He runs into his brother Ace outside, so the two decide to grab lunch together near the office with a credit card that Ace may have swiped from Garp. They go a little overboard when ordering, but their gramps probably orders twice as much as the two of them combined, so neither brother feels an ounce of guilt. Nevertheless, even with their ability to consume anything, it takes them both a while to finish their meal.
“Their new menu items are awesome! Right, Ace?”
Ace is dead asleep in a pile of leftover chicken bones, but not too far off behind him, Luffy can see Coby trekking in their direction, towards the office. He looks haggard and disheveled despite being in completely new clothes, but any weariness disappears as he perks up again the moment he sees Luffy. Luffy smiles and waves him over as he shakes Ace with his other hand. “Hey! Coby! You feeling better?”
“Luffy—”
He stops when he spots Ace, who instantly wakes up after sensing Coby approaching and instinctively puts a hand over Luffy’s.
“Oh,” Coby says, looking dejected. “I hope I’m not interrupting.”
“Huh? Interrupting what?”
Ace glares and sniffs towards Coby, nose scrunched as if offended by the scent. “Who the fuck are you?”
“That’s Coby!” Luffy says with a big grin. “Coby, you leaving already?”
His brother scowls at the poor young man which manages to scare Coby off despite the bits of fried chicken all over his face making him look less intimidating. “This is the dweeb you keep talking about?”
“I’ve got a lot of tickets to close out, so…!”
Luffy waves goodbye, a little disappointed as he watches the retreating figure run off further and further away. “See you later, Coby!”
“Don’t get involved with that guy,” Ace growls. “He reeks of AXE body spray.”
“Heheh,” Luffy chuckles. “That’s typical IT guy stuff. He’s harmless.”
“I’m serious. He’s hiding something.”
Luffy picks at his teeth while Ace nags at him (something about it being that time of the month or how Sabo might wake up late, to go home right away after work, to stop losing his scarves and beanies, typical big brother things), but as usual he doesn’t really listen. Instead he gets up and walks away while whistling a nondescript tune.
Ace’s voice fades as he gets further away. “Be home before dark!”
He kills time at a local arcade, even if he’s not particularly good at video games (he’s terrible with anything that doesn’t require button smashing), only to get kicked out after getting into a fight with some giant angry guy with jaggy red hair. The redheaded idiot actually put up a pretty good fight because Luffy of all people is tired after he leaves the arcade. He looks up and sees the sky getting darker, with heavy clouds rolling in, and shivers, wishing he would quit losing his scarves and beanies.
The sun has set, but there’s still enough light filtering through the clouds to take a shortcut home through the woods. He kicks at random rocks and sticks, pouting because he didn’t get to hang out with Coby much today, but at least there’s always tomorrow. His whole body is a bit sore from fighting that redheaded guy, so his pace is slower than usual, and by the time he’s halfway to his house, it’s already well into the night.
The clouds clear and the moonlight shines like a spotlight in the middle of the path, where he suddenly sees a familiar pink-haired young man stumbling out from a bush, collapsing on the forest floor with his face in his arms, writhing in pain.
“Coby!” Luffy rushes over, kneeling by the young man. “You okay? Who did this to you!?”
“Luffy! Stay away from me!”
Coby pushes him away and gets up, only to fall over. He winces. “Don’t come near… Luffy, you have to run…!”
“No,” Luffy insists, as stubborn as always. “I can help.”
“I….”
Luffy’s eyes widen as he sees silver and pink fur growing all over Coby’s skin.
“Coby, you’re a werewolf too?”
“N—wait, what?”
“Ace is a werewolf, too! Let’s get you back to our house!”
“Ace…?” he growls.
He suddenly grabs onto Luffy by both arms. Luffy looks down at Coby’s hands on both sides of him, now fully large, monstrous claws covered in pale pink, almost white fur. Then Coby whines like a kicked dog despite growing bigger and bigger.
“That guy who was with you? You… you live with him?”
“Yeah! He’s my brother,” Luffy explains, trying to pat Coby’s hands in a soothing motion. “Come on, Coby! Let’s go! We can help you!”
For a second, Coby looks relieved. Luffy looks down at a pink tail, wagging back and forth, and looks back up again, smiling wide to reassure the young man holding onto him. But that second of relief proves too brief as Coby’s entire body begins to spasm again.
“I’m not going to make it,” Coby groans, his jaw extending while the rest of his bones are snapping, growing with a terrible sound. His claws dig into Luffy’s arms as he grips Luffy with desperation. “Luffy, run, please!”
“I won’t leave you,” he says resolutely. But even if he wanted to leave, he couldn’t—Coby’s grip becomes tighter, too tight.
He winces, eyes shutting at the pain at being held so tightly where he’s already had bruises from fighting earlier. He whispers to Coby that it’ll be okay, that they’ll both be safe, to think of the sun, that’s he’s here for him, because these things sometimes (sometimes) work with Ace when his rash older brother gets too angry and accidentally transforms. But after what feels like eternity, when he opens his eyes again, he’s met with a full-blown werewolf towering over him, clothes torn to shreds, snarling at him with a large set of razor-sharp teeth.
“Coby, Coby! It’s me!”
The silver-pink werewolf sniffs curiously at the young delivery man trapped in its claws. Coby licks at Luffy’s face, and again at the scar underneath his eye, and for a second he thinks maybe he’s getting to the human consciousness within. Coby nuzzles his snout along Luffy’s neck, sniffing deeply at his scent, his fur tickling Luffy.
“Yeah, that’s right Coby, it’s me, Luffy,” he says, bringing his hands up to pet at Coby’s face and head. “Let’s go home.”
Coby whines, bucking his hips against Luffy.
Luffy stares down in shock at the large, heavy hard cock resting against his belly. A shiver shoots up his spine like lightning and his mouth goes dry.
“Hey, wait,” he yells as he’s pushed down, suddenly finding himself trapped between Coby’s now enormous body and the forest floor on top of shreds of Coby’s clothes and soft foliage like a poor excuse for a bed. He pushes at the beast above him to no avail, arms already weak from having fought earlier that night. Even in peak condition, he doubts he could have budged Coby, now too broad and made entirely of hard muscles.
Luffy tries squirm, to crawl backwards, away from the werewolf now desperately and blindly rutting against Luffy’s small body, but Coby grabs Luffy with one giant claw and flips him over ass-up with ease while tearing at his clothes.
“Coby, wh-what, what are you… oh, oh, Coby, don’t—”
He feels the length of Coby’s enormous cock pushing against the lips of his bare pussy with every jerk of Coby’s mindless thrusts, rubbing his clit so roughly it burns, but drives Luffy mad because it feels so good that he of all people is at a loss for words.
Luffy moans, trying to elbow at Coby even though a sick part of him is enjoying the sensation too much.
Coby growls and grabs Luffy’s arms, pinning them against his back.
Luffy laughs, even as Coby doesn’t stop humping him like a crazed, rabid dog, because he suddenly thinks about one day not long ago when a shy Coby told him that he loved the way Luffy laughed—so maybe, just maybe, if Luffy laughs Coby will wake up. He chokes out a breathless laughter as the werewolf above him continues rutting against his heated, electrified body.
“This isn’t you, you’re, oh fuck… Ha, ha,” Luffy tries to laugh. “It’s me, it’s—ah!—it’s Luffy…!”
He gasps as he feels Coby stopping behind him, and he sighs in relief, even as his wet cunt is now dripping and yearning for more.
Coby howls, and in the far, far distance he can hear others howling in response. It’s beautiful, almost calming, even as his heart threatens to explode out of his chest, beating so loudly Luffy can’t even hear his own thoughts. But the werewolf doesn’t loosen his grip onto Luffy, instead pushing him further into the dirt, his face and knees digging into the messy forest floor.
“Coby,” he breathes, quiet, heart stopping entirely as he feels the huge, thick head of Coby’s hard cock against the entrance of his cunt. “Don’t—”
He screams when Coby slams deep into him, shoving that beastly cock in and out of Luffy’s tight cunt without even a second to adjust. It’s inhuman, how long and thick that member is, pulsing and burning, filling in every inch and centimeter of Luffy’s wet heat.
It hurts. Luffy’s always wanted this, but not like this, not when Coby barely has any control over his own body. It’s not right, he tells himself, because neither of them are free—Luffy’s trapped by fierce claws and Coby is trapped by this curse the full moon brings him, trapped in the mind of a wolf and trapped by some primal instinct. But even though it hurts, even though he feels as if he’s being torn apart, even though it’s wrong, Luffy spreads his legs wider, arches his back for more like a bitch in heat, letting Coby’s thick cock violate the deepest part of him, again and again.
“Wake up, Coby, please,” Luffy begs, “It feels so—it, you—”
He’s big, too big, bigger than any of the dildos he’s used on himself at home whenever he thinks about Coby. The Coby above him is nothing like the sweet, dorky Coby he imagines as he fucks his own pussy alone at night with long, smooth movements, hitting just the right spot every time; instead, the Coby with him now is relentless, messy, pounding into him without care, filling Luffy with both pain from his cunt being stretched and abused beyond belief and a searing pleasure that leaves him craving for more.
“It feels so good,” he moans, unable to help himself.
He hears growling too close to his ear, causing his heated skin to crawl as if electrified. He squeezes his eyes shut, trying to tune out of the sound of the deep, guttural growling, instead hearing the repetitive slapping of skin against fur, but freezes when he feels cold wet fangs against his neck. He’s going to bite me, Luffy thinks.
But when Luffy opens his eyes he sees Coby biting his own arm, stopping himself from harming Luffy.
“Oh, Coby,” Luffy both sobs and laughs, because even when succumbed to the beast inside, Coby’s still so kind, while Luffy is selfishly taking Coby’s cock like a slut, moaning his name over and over again like it’s the only word he knows.
Coby doesn’t let up, releasing his jaws from his now-wounded arm as if it was nothing, licking at Luffy’s neck as he continues fucking Luffy’s pussy without mercy.
“So close,” Luffy whines, legs shaking as his entire body tenses and a low fervor spreads to his hot belly. “I’m gonna come—”
He screams as his toes curl and a white-hot sensation explodes within him, sending near-painful shock waves of pleasure through him until his mind is completely blank. He doesn’t know how much time has passed until he can hear Coby groaning and growling again, the sound of it clearing Luffy’s mind almost like lifting up a foggy curtain, as he pushes Luffy further into the ground, so much so that his knees burn from the friction of being fucked on the forest floor. His eyes snap open as he feels that hot girth deep within him now throbbing wildly against the walls of his pussy.
“No, don’t, don’t come inside, you have to turn back first then you can come inside, wake up, wake up, Coby, ah, ah, AH!”
Hot white seed spills into his cunt, filling him up more than he ever thought possible. It feels so good but it’s so much, too much, the heat and Coby’s huge cock still pounding into him over until the darkness of the night starts to overtake his vision and he passes out.
---
Luffy wakes up with a start.
He doesn’t recognize the room he’s in. It’s both fairly empty and messy. The bed he’s in is huge and takes up most of the room, and there’s an impressive computer set-up next to it. Random clothing items and broken chains are strewn about, including a few scarves and hats of his he thought he lost.
Even though there’s more than enough space in the bed for the both of them, he looks down to see the human-looking pink-haired man asleep, kneeling at the bottom of the bed, as if praying. His left arm is poorly bandaged and blood-stained. He groans and shifts, but soon his eyes suddenly open and he gapes at Luffy.
“L-Luffy…”
“Coby! I’m—”
“I’M SORRY!” Coby yells, prostrating himself before Luffy.
“I like you so much, I couldn’t help it. Even though I love you I did something terrible and even brought you with me here instead of taking you home like a real gentlemen,” Coby rambles, crying. He lifts his head up from the ground and Luffy tries not to laugh at how gross his crying face is, covered with tears and snot all over. “I should turn myself in…!”
“You love me?”
“You started telling me to wake up but it felt so good, I thought I was dreaming except you felt so real and so amazing and I bit myself and I felt it hurt but I still couldn’t stop—”
He punches the pink-faced hysterical man square on the nose and shakes him with sore, bruised arms. “Hey! Coby! Get a hold of yourself!”
Coby freezes, staring at Luffy with wide, red puffy eyes from crying so much.
Luffy asks again, “Did you say you love me?”
“Y-yes,” he answers, quietly. His entire face is red now, and not only is his face stained with tears and snot, but now sweat, a complete nervous wreck—nothing like the beast from last night.
Smiling from ear to ear, Luffy launches himself at Coby, the two toppling onto the messy floor of the studio bedroom.
“Me, too! I love you a lot!” Luffy laughs, squeezing Coby tight even though his body is aching everywhere, his heart suddenly feeling light and airy and free. “Say you love me again!”
“I love you,” Coby gasps. “I… I love you, Luffy! Since you saved me, I’ve always—”
“HEY! HEY!! LUFFY! ARE YOU OKAY? I KNOW YOU’RE IN THERE! TALK TO ME!”
Someone bangs on the window with intense force, startling Coby enough to jump to his feet.
“Wha…? How? We’re on the fourth floor!”
“Aw man, it’s Sabo!”
Luffy jumps up, but nearly falls over, his legs strangely weak and shakey like jelly. Coby catches him. The places where Coby's hands are start to tingle, a pleasant warmth that feels both fantastical and natural.
“Who?”
“My brother!”
Luffy clumsily walks over, almost tripping over his own feet, and yanks at the curtain, gesturing at the floating vampire on the other side of the window for Coby as if it were completely normal. It’s still dark outside, but the sky is covered in dark clouds, almost pitch black.
“Luffy! Thank goodness I put a GPS tracker app on your phone…! You know you have a curfew during full moons!”
Sabo points a menacing, sharp finger at Coby, barring his fangs at full length, and Coby flails over in shock and bewilderment. “Now hurry up and invite me in so I can save you from that creep!”
“Coby’s not a creep,” Luffy pouts. “And I don’t need saving.”
“Yes you—wait, that’s Coby? That IT boy you keep talking about?”
Sabo turns his nose up at Coby, glaring down at him with glowing red eyes.
“Okay, Coby, I promise I won’t kill you if you invite me in. Just say I’m allowed in. Come on, hurry. Don’t be scared.”
“Um… I don’t think I should,” Coby says, hiding behind Luffy and nervously trying not to make eye-contact with the floating, outdated-looking blonde British man pressing his entire crazed face, fangs and all, against the window. “Luffy, is your brother a… a… vam—”
Luffy points and laughs hysterically at Sabo from the other side of the window.
“That’s why I’m always telling you I don’t want to be a vampire!” he laughs, sticking his tongue out.
“By gods, there’s fur everywhere,” Sabo says incredulously as he spies into the messy room with his scarred eye. “Is this boy a werewolf!?”
“Yep! Just like Ace!”
His eyes widen as he looks down at Luffy's body--Luffy follows his gaze and realizes he's wearing an oversized shirt and pajama pants he doesn’t recognize, most likely Coby's.
“Luffy, please tell me he didn’t touch you,” Sabo practically begs. “He didn’t, right, Luffy?”
Luffy shrugs uncomfortably under Sabo's overbearing gaze, crossing his legs together when he feels leftover cum dripping down his thigh.
“Answer me, Luffy! You know can turn into a werewolf if you have unprotected sex with one, right!?”
Luffy whips his head back towards Coby, whispering, “Is that true?”
“I-I don’t know,” Coby confesses. He looks completely frazzled and overwhelmed. “I only just turned a couple months ago. Do you feel any different, Luffy?”
“Nope. Maybe we have to try again,” Luffy suggests, much to Sabo’s dismay.
“AGAIN? I really will kill you, you bespectacled little cretin,” Sabo hisses, clawing at the window. “Now invite me in, Luffy! Stay away from that damn four-eyed dog!”
Luffy sticks out his tongue again while Coby frantically tries to get the two to settle down. “No way!”
“Okay, okay, it’s fine, I am not mad,” the older brother says through clenched teeth, clearly trying to pass off as cool, calm, and collected despite his face having MURDER written all over it. “Let’s talk about this more at home.”
“No, I want to stay here with Coby!”
“Luffy, I’m not going to argue with you here.” Sabo moves one of his hands away from the window and behind his back and gives the two a full-toothed (fangs and all) smile that was the opposite of reassuring. “I promise I won’t kill him if you come back home. Trust me.”
Coby takes Luffy’s hand and squeezes it. “Mr. Sabo, I swear I’ll take full responsibility—”
“Responsibility? Responsibility? You defiled my little brother, the only way you can take responsibility is with your life!”
“Sabo, stop being weird!”
The three are suddenly interrupted by loud police sirens. They can see flashes of red and blue outside the window. The three peak down to see two scrawny police officers, one with a megaphone and the other writing in a small notepad.
“Sir,” they hear over a megaphone, “This is a no-fly zone. Please come down this instant.”
“Dammit, it’s the coppers.” Sabo scowls and disappears in a puff of smoke. When the smoke clears, Coby and Luffy barely make out the figure of a small bat fluttering about in the darkness. Sabo’s faint voice echoes to them. “Luffy, at least promise me if you do turn that you won’t pee everywhere like Ace does.”
“I won’t,” Luffy lies.
Sabo huffs. “Okay, then come back soon and bring Coby with you, I swear I won’t tear him apart limb by limb.”
Luffy knows Sabo is lying, but just laughs, squeezing Coby’s hand as they watch his overbearing older brother fly away into the pitch black night.
“Bye Sabo,” Luffy yawns.
Coby pulls the curtains back, leaving the two police officers to bicker about how exactly to enforce non-vehicular aviation law, while Luffy pulls him back towards the bed. Tired and at a loss of what to do next, they tumble into the bed sheets, not letting go of each other, laughing softly at nothing in particular, like their happiness is spilling out of them despite everything that's happened tonight.
“Hey, Coby.”
“Yeah, Luffy?”
“Do you know when the next full moon will be?”
He looks at Luffy.
“Yeah,” he says. “Why do you ask?”
Luffy smiles to himself before yawning again.
“No reason.”
Coby kisses the back of Luffy’s hand.
“Goodnight, Luffy.”
“Goodnight, Coby!” he says with a grin, closing his eyes as he feels Coby wrapping strong arms around him.
He drifts off into a peaceful slumber while he reconsiders the pros and cons of becoming a werewolf.
