"Harder! Mierda, do you think I'm made of glass!?"
"No," Leon said evenly. "I think you're made of skin and fur and two centuries of bad decisions."
Luis snarled and thrashed on the bed, but was held firmly in place by Leon's hands pinning his wrists and Leon's hips steadily pounding him into the mattress.
Because even though Luis was a powerful werewolf, he had nothing on the raw strength of a vampire.
"Calm down, you overgrown puppy," Leon chastised.
"Fuck you!" Luis spat. "I'm not your puppy, and you're nothing but a glorified mosquito!"
Leon just rolled his eyes and kept thrusting.
This was how they spent every full moon. Luis was normally very in control of his baser instincts, resembling more a particularly flirty golden retriever than a bloodthirsty wolf. But on the night of full moons, it was a completely different story: Luis became antsy, irritable, and unable to settle down before he'd worked off the energy by hours and hours of either fighting or fucking.
Fortunately, Leon could provide both.
"You can't even fuck me properly!" Luis, apparently, disagreed. "All those muscles just for show, you uselessβah!"Β
His sentence cut into a groan as Leon snapped his hips up hard enough to jostle Luis on the bed, his whole body shaking with the intensity of it.
"What was that?" Leon asked smugly, picking up a rough pace of slamming in and out of Luis' now-pliant body. "Cat got your tongue, mutt?"
"Nngh," Luis commented. His head was thrown back against the sheets, eyes closed and his mouth parted enough that his canines peeked out.
Leon mentally translated that to, "Yes, fuck me, right there."
So Leon allowed himself to let loose. He used more of his strength, groaning at the feeling of Luis still so hot and tight around him as he fucked in deeper and harder than before.
"SΓ, sΓ, mΓ‘s duroβ¦!" Luis babbled, clawing at the sheets and clenching around Leon.
Luis' cock was so hard it looked almost painful, bobbing in time with Leon's brutal thrusts and leaking pre-come down the shaft. It would be so easy for Leon to get a hand between them and jerk him to completion, but that wasn't what Luis had asked for.
With a grunt, Leon threw one of Luis' legs up on his shoulder and braced his hands more firmly on the bed, never faltering from his rough pace. The new angle and added leverage made Luis sob from pleasure, and a stream of Spanish expletives and endearments alike fell from his lips as Leon kept going, nailing Luis' prostate over and over untilβ
Luis jolted and came with a scream, his back arching and his cock shooting untouched into the air. Leon's sheets ripped under his claws but Leon didn't care, too busy watching Luis come undone and feeling his body squeezing tightly around his cock.
Leon rode it out with him, slowly fucking him through the aftershocks and then stilling completely when Luis whined from overstimulation.
Luis took a shuddering breath and sank back down against the sheets. His stomach was covered in his own spendβthis was already the third time he'd come tonightβand by all accounts, he should be more than sated.
But Leon could read the signs. Though Luis was unusually quiet, his hands stayed gripping the sheets and a quiet growl escaped between his clenched teeth.
Luis wasn't done yet, and fortunately, neither was Leon.
Leon lowered Luis' leg back down but stayed inside him, then experimentally pulled out and slowly thrust back in. Luis hissed, the feeling probably uncomfortable so soon after coming, but he still bucked up to meet Leon's hips.
Taking that as the permission that it was, Leon quickly worked back up into a steady rhythm, quietly amazed at how much Luis' body could handle. Every slide of Leon's cock into his well-used hole seemed to gradually ease the tension in Luis' body, until his dick was back to full hardness and his quiet growls sounded more like pleased moans.
"There you go," Leon praised. Luis' breath hitched and his ear twitched in interest, so he lowered his voice and murmured, "That's a good boy."
"Β‘Joder!" Luis protested, even as his face went ruddy and his dick jumped from the praise. "Stop acting like I'm a pet dog!"
"If you're not, why does your tail always wag when I call you a good boy?"
Luis went still, and Leon knew he could hear the rhythmic thump-thump of his tail hitting the mattress even over the harsh slap of skin against skin. Half of Luis' tail remained squished between his back and the bed, but the visible part was very enthusiastically showing Leon how much he enjoyed this.
And then Luis glared at Leon and the wagging stopped, but it was a moot point now; Luis could control his tail if he wanted to, but most of the time it was an unconscious action, like breathing.
"Next time, I'll get someone else to fuck me," Luis groused.
Leon chuckled and reached for Luis' cock. "No, you won't."
"Mierda," Luis cursed, bucking up into Leon's hand. "Make me come again and I'll consider it."
It was an empty threat. Their arrangement just worked too well to jeopardize: Luis needed someone who could hold him down all night during full moons, fucking and arguing until he was finally tired out, while Leon required a willing partner to essentially be his personal blood bank. Conveniently, vampires had more than enough strength and stamina to deal with the full moon frenzy, and werewolves just so happened to have enhanced healing that allowed them quickly bounce back after, say, a vampire feeding from them.
Of course, vampires and werewolves were supposed to hate each other. But Leon and Luis had both been shunned by their own kindβostracized for wanting to coexist with humans and not hunt them for sportβand though they got on each other's nerves like nothing else, living with Luis was one of the best decisions Leon had ever made. They balanced each other out, fought well together, and Luis was the only person Leon had ever truly considered an equal.
Someone more sentimental might have said it was simply meant to be.
"Leonβ¦" Luis groaned. His claws dug into Leon's back and made him hiss: Leon wasn't pinning his wrists anymore and Luis had apparently taken that as an invitation to maul him.
"Yeah?" Leon asked, ignoring the sharp sting of the scratches. His body would heal them in no time, and he knew Luis needed this.
"Good," Luis simply murmured. "It's good. Don't stop."
"I won't. I've got you," Leon promised.
He squeezed Luis' cock on the downstroke and Luis moaned, his eyes fluttering shut as he went pliant under Leon's touch.
It never failed to amaze Leon how fully Luis trusted him. No matter how much they fought or how many insults they threw at each other, somehow they'd always find their way back here: Luis fully handing himself over for Leon to take him apart and put him back together.
"Luis," Leon murmured, thumbing the head of Luis' cock and moaning when it made Luis clench tighter around him. "You feel so good."
Luis whined and threw his head back, exposing the smooth column of his throat, andβ¦
Leon felt the familiar instinct to feed.
Rationally, Leon knew he didn't need to drink yet. He'd done so not even three days ago, and he could easily go a week without. But it was almost a Pavlovian response: each time Leon fed from Luis, it would inevitably end in sex, because Luis was a crazy bastard and actually enjoyed getting brutally bitten and having the blood sucked out of him.
Last time, Leon had bitten and fed from the soft skin of his inner thigh, and Luis had gone lightheaded as all the remaining blood in his body seemingly went to his cock. Once Leon was done feeding and Luis was begging to come, Leon hadn't even bothered wiping his mouth before wrapping his bloody lips around Luis' cock and teasing the tip with his fangs, and Luis had spent himself right then and there.
Leon's mouth watered at the memory. He kept staring at Luis' exposed neck and shoulder; he could see the sweat on the skin, could hear Luis' heart beating frantically in his chest, could imagine exactly how he'd tasteβ¦
"Leon?" Luis' uncharacteristically quiet voice snapped him out of it.
Leon met Luis' eyes and saw the red from his own reflected in them. His eyes were glowing bright red with bloodlust and he only now realized his fangs had extended of their own accord, resting heavy against his bottom lip.
Anyone in Luis' position would have been paralyzed from fear, seeing the most dangerous predator on the planet about to attack them. But Luis simply held Leon's gaze and lifted his hand to gently cradle Leon's jaw.Β
"Mi prΓncipe," Luis murmured. "What do you need?"
You, Leon wanted to say. Just you. Always.
Leon swallowed; his throat was so dry, and he wantedβ¦
"I just," Leon rasped, eyes locked on Luis' shoulder. "I know it's only been a few days, butβplease, can Iβ¦?"
"Of course, corazon." Luis smiled and tilted his head to the side, giving Leon better access. "Bon appetit."
Leon's instincts didn't care about the joke or the pet name: they only cared about being granted permission.
Moving faster than any other creature could, Leon surged down and bit into Luis' shoulder.
Blood roared in Leon's ears and endorphins surged through his entire system. He'd meant to only puncture the skin with his two largest fangs, but as soon as the first flood of Luis' blood hit his tongue, Leon was helpless to do anything but let out an animalistic growl and dig in with all of his teeth in a savage bite.
He distantly registered that Luis was screaming himself hoarse, his claws digging into Leon's scalp and back. His body clenched around Leon's cock and a spurt of warmth landed on Leon's stomach as he came.
Leon groaned long and loud, rocking into Luis' body while his fangs siphoned even more of Luis' delicious blood onto his tongue. He always tasted like smoke and the sun, like laughter and homeβ
Leon's thrusts stuttered as he abruptly came too, burying himself deep inside Luis and filling him with his release. For a second, it felt like he was flying, high on the euphoria of claiming Luis in the two most carnal ways possible.
Mine, Leon's entire body sang. He's mine.
It took a while for both the bloodlust to fade and Leon's erection to go down, but eventually, Leon pulled off Luis' shoulder with a gasp. He was shakingβboth of them were. Luis was whining softly and cradling the back of Leon's head, holding him close while Leon fed from him.
He always trusted Leon not to take too much. Because in the five hundred years Leon had been alive, Luis was the only one who wasn't afraid of him.
Leon's chest clenched and his cock pulsed with the last aftershocks, making him moan and bury his face against Luis' throat.
"Fuck, Luis," Leon murmured against Luis' skin, then lapped up the blood dripping from the wound on his shoulder. "Such a good fucking boy."
A choked whimper escaped Luis' lips and his still-soft dick managed a weak spurt, trapped between their bodies as Leon's words milked one last orgasm out of him.
Leon pushed up onto his forearms and simply watched him with a perverted sense of satisfaction. Luis had an arm thrown over his eyes and was taking shallow breaths, his skin shiny with cooling sweat and Leon's bite bright red like a brand on his skin.Β
He looked exhausted. Sated, but tired, and overwhelmed, andβ¦
"Beautiful," Leon whispered.
Luis laughed hoarsely. "Oye, stop teasing. It's your fault I look like shit."
Leon felt his pale cheeks flame hot with warmth. He really hadn't meant to say that out loud, so he opened his mouth to apologizeβ¦
And Luis promptly cupped his head and pulled him down into a kiss instead.
Leon's breath stuttered as Luis' mouth moved sloppily against his own. They didn't usually do this: it felt more intimate than their no-strings sex warranted, and Leon was always afraid of accidentally hurting Luis with his fangs.
But Luis didn't seem to care. He eagerly licked into Leon's mouth, groaning as he tasted his own blood and teased at Leon's fangs with his tongue.
So Leon let himself indulge. He pressed close and kissed Luis hard and messy, smearing red over both of their lips. Luis shuddered and tightened his fingers in Leon's hair, canines playfully nipping Leon's bottom lip before Leon's tongue bullied its way into his mouth and made him moan.
Leon reluctantly pulled away after only a few moments, leaving Luis flushed and panting to catch his breathβand thoroughly testing Leon's self-control to not just pin him against the bed and kiss him for hours.
Luis laughed breathlessly. "Dios mΓo, who taught you to kiss?"
A drop of blood slid down Luis' chin and Leon licked it up with the flat of his tongue, ending with a peck on Luis' lips. "You did."
"Mmh, I am a very good teacher," Luis said smugly, then shoved Leon's shoulder. "Now move, you giant bat, you're crushing me."
Leon huffed and got off Luis, rolling over onto his back. "Still think the muscles are just for show?"
"A little." Luis winked, then groaned, "Ugh, I need to sleep. For a week, preferably."
Luis turned onto his side and immediately scooted close to Leon. Because vampires always ran cold, and with both the full moon frenzy and vigorous sex, Luis was a furnace. Being close to Leon simply helped him cool off.
Leon knew it didn't mean anything, but he still enjoyed the cuddling.
Luis pressed up against Leon's side, then yawned before tucking his head in the crook of Leon's neck and shoulder. He was sweaty and covered in come and his lips were still smeared with blood, but Leon didn't care. Luis was usually meticulous in his grooming, so it was nice to see him disheveled for a change.
Feeling particularly fond, Leon reached over to pet Luis' sex-mussed hair. Luis didn't say anything, but he tilted his head to give better access, then sighed quietly when Leon scratched behind one of his ears. Leon smiled to himself as he heard the soft swoosh of Luis' tail wagging across the sheets.
Part of Leon wished this didn't have to endβthat Luis would call him pet names outside of sex and crawl into his bed for cuddles even on the nights that didn't involve the full moon or Leon feeding from him. That every night, Leon would get to kiss him and hold him and pet his ears even if they bickered until one of them fell asleep.
Because Leon loved this stupid mutt. But werewolves mated for life, and he wasn't about to insert himself where he didn't belong.Β
He'd wait for Luis as long as he had to. And since they were both immortal, that could be quite some time, but Leon didn't mind.
Luis abruptly stirred against him, and Leon gave him more space as he tiredly lifted his head, eyes still half-lidded from exhaustion. The sun was already starting to rise outside and a sliver of light painted Luis' skin a warm gold.
But then Luis visibly sniffed the air, and poetic sunrises were the last thing on Leon's mind.
Leon quickly pushed himself up. "What is it!?" he demanded, already reaching for the bedside table for a weapon.
Though Leon's senses were enhanced compared to a human's, they had nothing on a werewolf's. It definitely wouldn't be the first time Luis had sensed hunters coming for them, smelling the silver bullets and wooden stakes long before Leon did.
In this state, Luis was temporarily weakened and wouldn't be able to fend for himself. But Leon felt stronger than ever after such a good feed, and he'd do anything to protect Luis; if a hunter so much as stepped foot in the building, he'd rip their head off with his bare hands andβ
"The downstairs neighbor is eating bacon," Luis concluded.
Leon groaned and lied back down. "And that's relevant how?" he asked.
Luis' head flopped back down with a huff. "Because I'm hungry."
"Really? I'm not."
"Because you just ate from me, idiota!" Luis snapped, then settled and groused, "I want a steak. Rare."
Leon sighed but obediently got out of bed; it would be good for Luis to eat, especially since Leon fed from him so soon. "Fine."
"And a glass of wine," Luis added.
Leon didn't need to ask what kindβthey both only drank red.
"Alright," Leon said.
"The good wine."
At that, Leon bristled: he knew exactly which wine Luis meant. And Luis knew perfectly well that Leon had aged that bottle for well over a hundred years.
"No!" Leon snapped, turning to glare at him. "Bad dog."
As soon as the words left Leon's mouth, he regretted them. Luis' entire face fell and his ears drooped miserably, his tail curling protectively around himself like Leon had physically struck him.
"Bad?" Luis asked, his bottom lip trembling. His expression was full of betrayal and he looked like he was about to cry, his eyes shimmering wetly as he whimpered, "I was bad?"
Leon's cold, dead heart clenched painfully at the display.
"No," Leon said, "no, you're not bad. I'm sorry, I didn't mean it."
Luis sniffled. "Really?"
"Really," Leon said. "I'll go get your food and the wineβit's about time I opened that bottle anyway."
God, he'd do anything to not make Luis cry. The stupid wine wasn't worth seeing him so miserable over.
"Okay," Luis said. He was still pouting, but at least he didn't look on the verge of tears anymore.
"Just sit tight, I'll be right back," Leon promised, shutting the bedroom door.
It didn't even take enhanced hearing to hear Luis start snickering as soon as the door closed, and Leon belatedly realized that he'd been played.
Nonetheless, he headed for the kitchen with only a slightly irritated sigh. It was his own fault for falling for the same damn trick for probably the hundredth time.
Because even though vampires were widely regarded as both the most powerful and intelligent creatures in existence, they all had a weakness. For some, it was sunlight, or crucifixes, or the classic wooden stakes.
But for Leon, it would always be Luis and his puppy eyes.
