The soothing sound of the waves and the comforting heat of the afternoon sun has Luffy almost drifting off into sleep where he’s perched at the bow of his modest fishing boat. The boat rocks gently with the waves, and he fights to keep his eyes open as he takes in the sight of a calm sea. The sun rays hitting the surface makes the ocean shine brightly, and he smiles softly; content. This was where he felt at home, where he felt at peace.
The ocean had always called to Luffy, ever since he was a child. He fondly remembers running barefoot across the sand, feeling grounded and unguarded, the different sounds of the ocean like a symphony to his ears. The waves lapping against the beach, the seagulls, the children laughing, the ice cream vendor yelling. He remembers looking out across the vast expanse of the horizon, and proudly proclaimed to everyone that he was going to sail the seas when he grew up.
Luffy kept those memories close to his heart, always thinking back to those times when things were particularly rough. Growing up, his classmates would mock him for wanting to become a sailor, but he never let it bother him. At 24 years old, he was finally self-sufficient enough at fishing that he made a decent living off of it, spending the weekends at markets selling his catch. His booth was especially popular due to him being one of the few fishermen that caught sea monsters, their meat being an expensive delicacy, though catching them was known to be extremely challenging.
Usually he would be out fishing with some of his friends that viewed it as a hobby, and he had a bigger boat for those occasions. Today in particular, he decided to take his smaller boat out, not really planning on doing any fishing. It was such a beautiful day, and he just planned on frolicking on his boat, letting the waves take him wherever they pleased as the smells and sounds of the seas relaxed his body and soul.
He yawns and stretches his arms over his head, his straw hat falling to rest on his back thanks to the string securing it around his neck. He’s about to drop down from his perch when he sees something out of the ordinary from the corner of his eyes. He squints towards the horizon and sees what looks like something floating a couple of hundred feet away. He frowns before quickly making his way to the helm, turning on the engine as he heads towards the strange object.
As he gets closer he can see that it’s not a thing, but a person. He stops his boat close enough to be able to reach the body from the stern, and he climbs down the ladder swiftly. The body looks lifeless, and he wraps an arm around the waist of it and climbs back up the boat. It’s heavy, and very much taller than Luffy, but it’s not too much of a challenge to get it up on the boat. He places the body down on the deck and his eyebrows raise in surprise as he inspects it.
It’s not a human, that’s for sure.
“Merman,” he says to himself in disbelief.
Luffy inspects the merman, taking note of the black scales that cover his tail and how they glimmer with a golden shimmer as the sunlight reflects off of them. Where there aren’t any scales, there is tan skin littered with pale patches, and intricate black patterns that cover his chest and arms.
Tattoos, Luffy thinks, intrigued. The merman looks to be about 7 feet tall if you count the fin. Luffy has never seen merpeople up close before, as they’re known to be very elusive and secretive creatures. The general public still think that they’re just a myth, but sailors and fishermen know that they’re just hidden from the rest of the world for their own safety.
The few times that they will get caught, fishermen will turn to the black market to sell their scales, as legend says carrying them around will bring you good luck and fortune. Luffy didn’t particularly prescribe to superstition.
As he inspects the meaty tail of the merman, he wonders if it's frowned upon to eat it. After all, it doesn't look unlike a fishtail or the tail of a lesser sea monster... but the upper body of the merman looks undeniably human, and Luffy clicks his tongue in disappointment. He doesn't think he could eat him with a good conscience, even if he does look very tasty.
Luffy’s eyes flit over to the merman’s face and he crouches down next to him to get a closer look. The merman is breathing, very much alive, but unconscious. His pink lips are slightly parted, the gills on the side of his neck fluttering open and shut. His chest rises and falls heavily with labored breaths. As far as Luffy knows, merpeople can breathe on land, meaning the heavy breaths have to be due to something else.
Maybe he’s sick? He thinks. The merman’s brows are pinched together in pain, a thin layer of sweat mixed with sea water coating his face.
The merman has navy blue hair, still damp from the sea, and Luffy spots pointy ears sticking out from underneath his thick hair. He reaches a hand out to tuck a loose strand behind an ear, and he can’t help himself but to gently touch the pointed tip.
It feels like human skin, he thinks, fascinated.
A pained groan erupts from the merman and Luffy jumps back, startled. The merman stays unconscious but Luffy can see his eyes moving with unrest under his closed eyelids. Luffy frowns as his eyes rake across the merman’s body to find the source of his pain.
He spots blood slowly seeping out from a deep puncture wound located on the side of his thigh.
Side of his tail? Luffy thinks, correcting himself. He hadn’t seen the wound before due to the water most likely having washed away the blood.
Luffy’s eyes scour the boat and they land on a pile of towels, and he quickly grabs the biggest one and wraps it tightly around the wound. He settles back behind the helm and turns on the engine to steer them back towards shore. He doesn’t really have proper medical skills, but Chopper gave him a large first aid kit filled with all kinds of things, and something in there would have to be useful. Otherwise he’ll have to call for backup.
His eyes flicker back to the intriguing merman before he looks back towards shore, and he speeds up, his stomach churning with concern.
He gets there in record time and moores his boat to the wharf connected to his beach house. He climbs back onto the boat and carefully lifts up the merman before he slowly makes his way towards the house, not wanting to agitate the wound.
As challenging as it is to carry a seven feet tall merman, he makes it into the house with no incident, and gently places the merman on the soft bed in the bedroom. The merman’s cheeks are red with fever, and his whole body trembles with shivers.
Luffy quickly digs through his closet to find the first aid kit, grabbing a bottle of saline solution, gauze and a roll of bandages. He moves back towards the bed and carefully unwraps the towel from the tail, his eyes widening in surprise as he sees that the wound looks smaller.
It’s still bleeding, but it doesn’t look as deep. Maybe merpeople heal quicker? He breathes a sigh of relief, thinking that it actually looks like a wound he can handle himself. Luffy is known to be reckless and had to get lectured by Chopper enough times to finally teach himself how to care for minor wounds, which explains why he was given a medical kit in the first place.
Luffy begins pouring the saline solution on the wound when the merman suddenly wakes up with a start, sitting up abruptly. His eyes, wide with panic, dart around the room before they finally land on Luffy.
He hisses, sharp teeth on display as he violently flicks his tails towards him, and before Luffy has a chance to back off, the tail hits him in the middle of his chest and he flies across the room, roughly hitting the wall with his back. Luffy slides against the wall with a groan, rubbing the back of his head with a wince. He slowly stands back up on shaky legs.
“Ouch,” Luffy grins. “You’re strong.”
The merman’s chest rises and falls heavily, his face contorted with a pained grimace. He still manages to glare nastily at Luffy, who is slowly making his way back towards the bed.
Luffy holds his hands up and continues to approach the panicking merman.
“I’m here to help you,” Luffy says and points towards the wound on his tail. “You’re hurt.”
The merman’s brows furrow. His glare is still heated and he cocks his head in confusion before looking down at his tail. His eyes widen before the situation seems to catch up to him and he huffs out a frustrated breath.
It dawns on Luffy that maybe the merman doesn’t understand human speech.
He points at himself “me, Luffy,” before pointing at the wound and saying “me, help.”
The merman eyes him suspiciously before he hisses again but this time in pain, the adrenaline probably having worn off. He slumps back onto the bed and Luffy takes the opportunity to get closer, picking up the discarded bottle of saline. The merman doesn’t react violently again, thankfully, but his cautious gaze follows every move that Luffy makes.
Luffy once again pours the saline solution on the wound, and he sees the merman clench his fists in pain.
“It’ll be over soon,” Luffy says comfortingly, picking up the gauze and bandages. The merman huffs. Luffy gently places a hand on the tail next to the wound and chokes back a gasp. The scales feel cold, and they’re not as hard as he thought they would be. He strokes the scales with a finger and watches as they quiver under his touch, seemingly sensitive.
He clears his throat before he continues to tend to the wound, wrapping it before he sits back to admire his work. It’s not perfect, but it’ll do the job. He gets up to get a glass of water for the merman, but he pauses. Do merpeople even drink water? They live in the sea, does that mean they drink salt water? Luffy shrugs and gets a glass of water and some ibuprofen for the fever anyway, and he puts the items on the bedside table.
The merman eyes him and the items warily, his breaths still labored.
“This is for your fever,” Luffy explains even though he’s not sure the merman understands him. So Luffy touches his own forehead and points towards the pills. “Fever, help,” he repeats, speaking slowly.
The merman ignores the pills and tentatively picks up the glass of water. He brings it closer to his nose and sniffs before sticking his tongue out to dip it into the water. His tongue is long and split at the end, like a snake or lizard. Luffy looks at it, fascinated.
“Cool,” Luffy says, resting his chin in his hand while he looks at the merman.
The merman pauses his lapping of the water and looks at Luffy with a raised eyebrow. Luffy’s stare doesn’t waver, and he finally notices the enchanting color of the merman’s eyes. They’re golden, the same shimmering hue of gold that Luffy saw on his scales when they were bathed by sunlight.
“You’re beautiful,” Luffy breathes, mesmerized.
Those eyes suddenly droop, the eyelids heavy. Luffy sees how he looks more relaxed, but can tell that he needs rest. Luffy gently takes the glass from the merman and places it on the bedside table. He grabs a clean blanket from the closet and covers the merman with it, hoping he will get some sleep so he can heal.
The merman lies down on his side that isn’t wounded, turning away from Luffy, his back facing him. Luffy pouts, disappointed. He wanted to look at the merman some more, but he clearly wants some privacy.
Luffy takes a seat on the armchair by the window, looking at the exposed fin sticking out from the blanket. The sun is setting on the horizon and it bathes the bedroom in soft reds and yellows. The fin looks to be translucent to the naked eye, but under the colors of the sunset it glistens brightly like amber.
He’s never really told anybody about it, but Luffy has always had a fascination with sea creatures. He’s always loved the ocean, a fact that everyone he knows is aware of, but the creatures living in those unforgiving depths make him starry eyed.
The reason he started hunting sea monsters was because he saw it as a challenge that everyone said was near impossible. He can’t deny that he was also unbearably curious as to how they tasted, but the more sea creatures he saw, in all their different shapes and sizes, the more he became enamored with the beasts. They were just so interesting and cool, and the bigger they were the better. The harder it was to catch them, the better.
As his gaze rakes over the merman lying in his bed, he’s starting to feel a different kind of admiration, though. While sea monsters were cool and interesting, the merman was cool and beautiful. He wanted to touch the strong tail that effortlessly threw him across the room, he wanted to watch those scales quiver under his touch. He wanted to inspect the split tongue and sharp, pointy teeth closer. How strong were his jaws? Could those teeth tear into his flesh effortlessly? Would the merman rip him apart if he tried touching him? Luffy wants to find out.
Getting torn into chunks by a breathtakingly gorgeous merman isn’t the worst way to go, he thinks as he drifts off into sleep.
Luffy startles awake at the sound of a heavy thud and he blinks his eyes open to see, well, nothing, as it’s pitch black outside and in the bedroom.
He hears a pained groan coming from the other side of the room and realization hits him. He fumbles in the dark for the light and turns it on to see the merman lying in a heap on the floor next to the bed, his shoulders tense and gasping for air. Luffy rushes to his side and reaches out to him but the merman hisses and snaps his jaws towards him, a warning to stay away. Luffy hovers close by instead, desperately hoping that the wound didn’t reopen.
“Are you okay?” Luffy asks, at a loss for what to do, knowing not to expect a verbal response to his question. Maybe the merman needed to be in the ocean again? He’s not sure how long they could stay out of water.
Luffy waits until the merman seems calmer before he tries to approach him a second time. He crouches down next to him so they’re eye to eye, and Luffy points to the merman and then to the bed.
The merman purses his lips before he nods and Luffy bends down to pick him up, wrapping one arm around the merman’s waist and the other holding up his tail. Luffy vibrates with excitement when his hand connects with the cool scales before he slowly places him down on the bed. He sits down on the edge of the mattress, one hand resting on the merman’s tail. He can’t help himself.
He notices that the merman has torn off the bandages, and the only trace left behind of the wound is a scab. Luffy runs his hand softly across the healing wound, and the merman doesn’t even flinch.
Pleased that the merman isn’t hurt, Luffy relaxes in his seat on the bed.
“I wish I knew your name,” Luffy says wistfully.
“Me, Luffy,” he tries again, pointing at himself with his free hand.
“You?” He points at the merman, hoping he got his point across.
The merman watches him carefully, a calculating look on his face. He takes a deep breath before parting his lips.
“Law,” he rasps out and Luffy’s eyes widen at the sound of his voice. It doesn’t sound human, Luffy thinks initially. It sounds like static, like cutlery scraping against an empty plate, a sharp and imposing sound like it’s from another plane of existence. From hell, perhaps.
Luffy smiles brightly and looks down at his hand still on the tail.
“Law, huh?”
He starts moving his thumb in gentle circles across the scales, watching in fascination as they shift and flutter under his touch. The merman doesn’t protest, instead his eyes just track Luffy’s movements, an eerie silence settling between them.
Luffy’s gaze roams across Law’s body, traveling up his tail and across his chest. This close he notices how there are rogue scales on his torso too, randomly scattered across his patchy skin like little treasures for him to find. His eyes roam higher and zero in on the gills on Law’s neck and he reaches over to touch.
Law gasps as Luffy’s fingers softly stroke the gills, the feeling so similar to skin but not exactly. It’s softer, almost slippery, somehow feeling wet even though it isn’t. Luffy gently pushes in a finger between the folds, his eyes wide as he takes in the reactions of the merman.
Law’s eyes are closed and his neck stretched to give Luffy better access to his gills, his lips parted as he gasps softly. Luffy swallows, stopping his ministrations only to reposition on top of Law, straddling his waist. Law blinks, his eyes glazed over as he opens them to look up at Luffy, licking his lips.
Luffy puts both hands around the merman’s neck and starts stroking the gills on both sides at the same time, making Law let out a loud moan as he arches his back, almost bucking Luffy off of him. He grins, pleased, slipping his fingers past the folds as he continues to pleasure the merman.
He had no clue this would be the reaction he would get to his whim of touching, but Luffy isn’t complaining. Watching the beautiful merman writhe and moan underneath him is an image he never wants to forget. Law’s hands settle on his hips and he squeezes, those sharp nails digging into Luffy’s skin.
Luffy feels his dick hardening, tenting his cargo pants as he keeps soaking in the eerie symphony of the sounds leaving Law’s tempting mouth. His voice would terrify most, but Luffy finds it unbelievably arousing, goosebumps rising across his skin as the strange and distorted voice cries out with pleasure.
He finally leans in to capture those soft, glistening lips with his own in a slow and gentle kiss, his fingers still stroking the insides of Law’s gills. The merman parts his lips to press his tongue against Luffy’s, and Luffy opens up to enthusiastically invite it into his mouth. The split tongue of the merman feels strange, but not unpleasant. It’s longer and thinner than a human tongue, and it easily reaches the back of Luffy’s throat as they deepen the kiss.
Luffy slowly explores the inside of Law’s mouth with his own tongue, carefully maneuvering around the sharp, pointed teeth of the merman. He sweeps his tongue across the upper row of sharp teeth in a bold move and is surprised that they don’t break skin. They must need more pressure to do so, Luffy thinks, hungrily licking and sucking into the merman’s mouth, saliva running down their chins as they fall into the abyss of pleasure.
Law releases the bruising grip he had on Luffy’s hips to instead press against his crotch, fumbling awkwardly with the button and zipper as if he’s never had to deal with clothes before. He probably hasn’t, Luffy muses, stopping his fingerfucking of the merman’s gills to unbutton his pants, sliding them down just enough to get his cock out.
Law raises his eyebrows and sits up slightly to get a better look at Luffy’s dick. He looks intrigued at the sight, and Luffy feels his cheeks heating up at the intense gaze.
The merman hums, circling the head with a finger to spread the precum. Luffy groans at the touch, his cock already rock hard and leaking. Law smirks, his sharp teeth on display as he grabs Luffy by the hips and effortlessly lifts him to sit him further down his tail.
“Whoa,” Luffy exclaims, surprised but incredibly turned on by the strength displayed by the merman. Luffy might not be very tall, but he’s packed with lean muscle and heavier than he looks. He wonders for a moment why Law decided to move him, but as he settles on his new perch and looks down, he finally understands.
Where there previously was only rows and rows of beautiful scales, there is now a small opening amongst them at approximately crotch height if compared to a human. Luffy bends down to have a closer look, one of his hands slowly traveling up over the tail until he finally reaches the slit of what Luffy assumes is his pussy. Law leans back against the pillows on the bed, his hands behind his head as he watches Luffy with an amused smile on his face.
Luffy slowly enters the slit with his index finger and groans at the wetness inside. It’s warm and tight, the slick a consistency unlike what he’s ever felt before. It feels more like lube rather than slick or cum. He reaches further inside, his middle finger joining in as he explores the merman’s inviting insides. He pauses when he curls his fingers upwards and hits something bumpy and hard, and he furrows his brow in confusion.
He looks up at Law and sees that the smug expression is nowhere in sight, the merman instead looks unraveled as he throws his head back in pleasure, his knuckles white from the tight grip he has on the bed sheets. Luffy hears a ripping sound as Law’s nails tear through the cotton with ease. He keeps stimulating the hard spot and he gasps when he suddenly feels it move, pressing against his fingers until he’s pushed out of Law’s hole.
He laughs delightedly at what he guesses is the merman’s cock as it folds out of the slit, eventually straightening up and bending upwards to rest against Law’s stomach, clearly erect. Luffy is fascinated at the sight, as it looks unlike any other cock he has ever seen. The base is thick, much thicker than his own, and the shape is almost cone-like as it thins out at the top. The tip is a deep purple while the rest of the cock is pink, and Luffy thinks it kind of looks like a strangely shaped ice lolly if it wasn’t for the spikes covering it.
The spikes look terrifying at first, but when Luffy leans in closer to inspect, he sees that they’re rounded at the tips, and they’re colored a darker pink than the base. He reaches out his hand to wrap it around the cock and Law whines, pushing his hips up as he chases the pleasure of Luffy’s touch.
The cock is extremely slippery, coated by the lubrication from his cunt, and Luffy’s hand easily strokes it. The spikes seem to be able to move in multiple directions as they bend with the movement of his strokes, and it doesn’t seem to be uncomfortable for Law as his moans grow even louder.
“L-Luffy,” he manages to rasp out with his strange voice, causing Luffy’s heart to soar. Luffy leans down to press kisses on Law’s chest, tracing his tattoos with his tongue. One of Law’s hands comes to rest on the back of Luffy’s head, and he pulls on Luffy’s hair whenever his tongue licks against a particularly sensitive spot. Luffy continues to jerk the merman off as he latches his mouth onto a gorgeous pink nipple and sucks. Law’s sharp nails dig into his scalp and Luffy moans against the merman’s skin at the pain mixed with pleasure. He wants to map out every single part of Law’s body, to figure out what makes him lose himself in pleasure the fastest, the feel and taste of his body making Luffy more turned on than he’s ever been in his life.
He moves to suck on the other nipple, pleased at the swollen and puffy state he left the first one in. His hand slips on a particularly rough stroke of Law’s cock and he accidentally dips his thumb into the slit below it. Law’s body jerks and his nails scratch across Luffy’s back, undoubtedly leaving a trail of bloody lines.
Luffy’s eyes widen as he realizes he can still finger the merman while his cock is out. He sits back up again and thrusts two fingers into the slick hole while continuing to jerk him off with his other hand.
He can feel Law’s tail quivering underneath him as he continues to roughly thrust into his pussy, and Luffy watches his thick fingers stretching the hole out. His own cock throbs at the sight, more pre-cum leaking from the tip, and he wants to be inside that soft and wet heat so badly, but he can’t get enough of pleasuring Law like this.
Luffy is still hypnotized by the sight when Law reaches out his hands to grab his wrists, stopping all movement. Luffy looks up at him, bewildered and slightly disappointed, but Law releases his wrists to wrap his arms around Luffy’s neck, pulling him up his body. Luffy kicks off his pants and properly positions himself above the merman with a knee on each side of his tail. He looks down and sees his cock almost lined up with Law’s hole and he trembles with anticipation.
Law reaches out a large hand and wraps it around Luffy’s cock, slowly jerking him off. Luffy moans, burying his face into the merman’s neck, nuzzling his nose into the gills. He feels before he hears Law’s breath hitching and he grins, his tongue darting out to lick in between the folds.
With a loud growl, Law releases his cock and presses Luffy closer to his body, and Luffy whines at the feeling of his dick rubbing against the cold scales. Luffy fumbles a hand in between their bodies and finds Law’s cunt, lining his dick up with it. He takes a deep breath and braces himself, slowly entering the tight heat of his hole. Law’s dick twitches as he enters, the spikes hardening the deeper Luffy sinks into the wet depths, groaning into Law’s neck at the feeling.
Luffy is gasping for air, feeling like he’s on cloud nine. He’s never experienced pleasure like this; it’s like he’s been injected with pure euphoria, and he has to stay still unless he wants to blow his load immediately. Law huffs underneath him, impatiently bucking up his hips and making Luffy clench his jaw as he tries to keep himself from cumming.
A long moment passes where only the sounds of their heavy breaths can be heard before Luffy raises his head and lifts himself up on his elbows. He looks down at the fucked out expression on Law’s face and starts to slowly move his hips, pulling back almost to the tip before roughly thrusting back in. He can feel the base of Law’s cock with every thrust, the tip twitching and leaking, and a translucent liquid pools on the merman’s stomach. Luffy looks down at his cock disappearing into Law’s tight little hole, and he almost cums at the sight of it.
“You feel so fucking good, Law,” Luffy gasps out, his whole body feeling like it’s on fire; a fire so pleasant he wants to be consumed by it.
The merman scratches deep lines across his back with each thrust, and Luffy moans at the stinging pain as it mixes beautifully with the pleasure.
Luffy raises himself further, bracing himself with a hand on each side of Law’s head and he starts fucking the merman in earnest, making sure to keep his eyes open so he can enjoy the show of Law’s mesmerizing facial expressions as he takes Luffy’s cock. Law’s eyes roll into the back of his head at a particularly rough thrust, and Luffy does it again and again, addicted to the sight of the merman drunk on his dick.
He babbles praises, his mouth uncaring of whether Law understands him or not. He’s decided he will tell the merman how good he is, how amazing he feels, and how beautiful he is despite the apparent language barrier.
He feels himself getting closer to release faster than he’d like, but he can’t stop now, it feels too fucking good and he leans down to press a sloppy open-mouthed kiss against Law’s lips, which ends up with them just breathing into each others mouths as spit dribbles down their chins, too far gone to properly lock lips.
”Law, fuck- ahh,” Luffy groans as he finally cums, fully sheathed into Law’s cunt as he gets milked for every single drop. He feels the walls of the merman’s hole pulsating as his cock spurts out an unreal amount of cum, and Luffy sees black spots at the edges of his vision as he has the most intense orgasm of his life.
Luffy collapses on top of Law, their sweat slicked chests pressed against each other as they both pant with exertion. Luffy can feel wetness all over his back and he briefly wonders whether it’s sweat or blood, before coming to the conclusion that it’s probably a mix of both.
Law’s hands softly stroke his back, his fingers tracing the red tracks of the marks, and Luffy sighs into his neck, his body soft, pliant and content.
He shifts slightly on top of him, and he gasps when he feels the hardness of Law’s cock press against his stomach. Luffy gingerly raises himself up and looks down at Law’s weeping cock.
“You didn’t come?” Luffy asks softly, sitting up on Law’s tail.
Law looks up at him, cocking his head as his hand travels down his chest to tug at his dick. Luffy licks his lips as a plan starts forming in his mind. He’s not done with the merman yet, far from it.
Luffy dips two fingers into Law’s cunt, effectively soaking them with slick. Law gasps, his tail trembling as Luffy fingers his sensitive hole. Luffy slowly pulls his soaked fingers out and reaches behind himself, slowly pushing in a finger into his asshole.
The merman watches him curiously, still slowly stroking his cock. Luffy feels his own dick filling out again at the sight of Law touching himself combined with the finger in his hole, and he slides a second digit in. He scissors his fingers effortlessly, the slick from Law’s cunt proving to be the best lube he’s ever used. He gasps softly when he pushes in a third finger, the burn of the stretch making heat coil in his stomach, and he startles when he feels hands on his hips.
Law’s cock leaks heavily where it’s resting on his stomach, and it seems like his patience has run out as he abruptly lifts Luffy, making his fingers slide out of his hole as he’s lined up with the merman’s length.
Luffy gulps, reality dawning on him as he compares the size of three fingers to Law’s inhuman cock.
The merman doesn’t seem to notice his hesitation, or if he does he doesn’t care. He starts pushing Luffy down on his cock and the tip goes in easily to Luffy’s relief, but the further down he drops, the more intense the stretch gets.
The feeling of the spikes against the walls of his insides feel unlike anything he’s ever felt before, and he finally remembers to breathe as Law gets closer and closer to bottoming out inside of him. He feels himself relaxing slightly with each deep breath, but the pain of the unbearable stretch makes him flinch and groan out in pain rather than pleasure.
Law rubs his hips comfortingly, looking up at him with softness in his eyes as he finally bottoms out inside of him. Luffy pants heavily, droplets of sweat and tears streaming down his face as he tries to get used to the strangely shaped cock inside of him.
He feels so goddamn full, and Law shifts slightly, making Luffy arch his back and gasp in surprise. Law’s cock is pressing against his prostate, making Luffy’s cock leak, already close to the edge for the second time. He momentarily forgets all about the pain and raises himself up before dropping back down on Law’s cock. They both groan in pleasure, the wet sound of Law’s cock inside of Luffy’s ass sounding absolutely filthy. Luffy starts a brutal pace of riding the merman, raising himself up and down, chasing the pleasure of the spiky cock pressing against his bundle of nerves.
Law’s fingers dig deeper into his hips, and he starts lifting Luffy up himself, harshly pulling him down onto his cock. Luffy can feel the spikes getting harder, but it only increases the pleasure he feels inside of him.
Luffy screams at a particularly rough thrust against his prostate and he reaches his climax untouched, cum splattering both their chests. Law doesn’t slow down, he keeps pounding into Luffy’s overstimulated prostate, and Luffy starts flopping over, his body seeped out of all strength. The merman is unfazed and only wraps his arms around Luffy’s waist, holding him tightly as he keeps fucking into Luffy’s abused hole.
The merman pants heavily, moans and gasps escaping his lips. His pace starts becoming more and more frantic and Luffy is powerless to do anything but groan as he’s used like a mindless hole for Law to fuck into.
A few rough and fast thrusts later, Law stills, tightly clenching his arms around Luffy’s body as he releases his load deep into Luffy’s insides. He feels the spikes harden even more inside of him, and he gasps in surprise at how much cum is being released into him. He can feel the hot liquid coating his walls, and he’s sure it would leak all over them if the base of Law’s cock wasn’t wide enough to plug him.
They’re both panting, and Law loosens the tight grip he has on Luffy’s body before he nuzzles into his neck. Luffy hasn’t seen this affectionate side of the merman yet but he’s not going to complain. He feels sore everywhere, his lower back and asshole throbbing with pain.
Luffy tries to lift himself up off of Law’s cock but he can’t, and he frowns before looking down at Law who’s gazing up at him with a lovesick look on his face. Luffy recognizes it as the same facial expression his friend Hancock gives him and he furrows his brow in confusion.
“Why can’t I get off your dick?” Luffy asks, dreading the answer.
Law just shakes his head and pulls Luffy to his chest, stroking his hair as his snake-like tongue darts out to lick Luffy on the cheek.
Luffy starts thinking about the spikes again and it dawns on him that those aren’t just spikes, they’re hooks, and he briefly remembers watching some nature documentary with Robin about how some species have hooks on their genitals to assist with mating. Luffy groans and relaxes into the merman’s arms, his fate sealed for the day, he supposes.
He can’t help but smile as he feels the merman happily nuzzling into his hair, a content rumbling sound vibrating in his chest.
Maybe this isn’t so bad, Luffy thinks as he lets himself relax into Law’s embrace, closing his eyes as he drifts off into a peaceful sleep.
