(shadowhunters, malec, this world inverted verse)

summary: Most children get video games when they turn ten, or maybe a cool selection of movies and a toy car. Alec gets a family curse.

(He doesn’t want to die, but twenty-five seems so far away. He’ll be so old by the time the curse takes him.)

.

His time is running out.

The awareness hits him first thing when he wakes, the way it always does. And just like every other morning, Alec ignores it in favor of turning over and cuddling deeper into his boyfriend’s deceptively muscular arms. Who knew there was so much hiding under those unassuming cardigans? Alec thanks his lucky stars every day for the mysterious party-crasher who snuck into his gala and upended his life in all the best ways.

It’s been six months and Alec still hasn’t found a way to tell him he’s dying.

Which is a bit dramatic, even for someone who thrives on being dramatic. Alec’s not dying, not really. But his time is limited. It’s an immutable fact that’s been part of his life since the day he turned ten and his mother took him aside.

“It’s the family curse,” she explained, her eyes wet with tears she refused to shed. “Centuries ago our ancestors defeated the demon hordes that threatened humanity but it came with a price. You need to be brave, Alec. Can you do that for me?”

Alec kisses Magnus’ forehead and gets dressed to meet his first client of the day. One more day and then he’ll tell him.

.

(He doesn’t tell him the next day.

Or the next.)

            Remus was an oddity, and Logan didn’t like oddities—or he liked them too much, some might say. He had never had much interest in the darker side of creativity; like Roman, Remus was just a lot of puff and nonsense, and Logan really had no time for that. However, unlike Roman, Remus was different. Anatomically, to start, and most interesting of course. Remus had tentacles. He was an octopus in the same way Deceit was a snake and Virgil was a spider. Thomas’ more dark sides—a ridiculous nickname—had animal traits, and where Virgil’s was as subtle as stridulation, Remus was an eldritch dream come true.

           Logan had taken to following Remus, subtly, at a great distance; Remus was never the least bit aware of his surroundings, making him an easy target for case study. Logan kept meticulous notes about his observations from how quickly Remus could annoy Deceit to the way he tended to prefer heights and—of course—the tentacles.

           Size. Shape. Color. Probable weight, mass and density given what could be observed with the naked eye.

           As he recorded more and more, Logan grew less and less satisfied. He wanted to experience more. A good scientist can’t just rely on his eyes, and Logan had four senses more just aching for a piece of the action. Logan decided to be direct, but then he remembered Virgil’s warnings about direct approaches when it came to social exchanges, and it gave him pause. He would need to be cautious, gather more data, find out what Remus liked beyond eating deodorant and annoying Deceit with excessive physical affection. Logan was reminded briefly of Patton every time Remus got touchy, and that didn’t help quell his desires at all.

           Logan tried to get closer, linger longer, and he was fairly successful, gathering snippets of information that might end up helping him in his quest. With success, comes carelessness, and Logan found himself following Remus to his room, peeking through the half-open door.

           He paused in his watching to scribble down notes, and when he looked up, Remus had vanished. As he leaned closer to the crack in the door, Remus appeared just on the others side. Logan jumped, falling back on his butt, “R-Remus!”

           “If you wanted to see me naked, Logan all you had to do was ask,” the chaotic side purred. “Come in.”

           Logan watched Remus saunter back into his room, and then, with a grim resolve, he stood and followed, closing the door. Remus was watching him, hands on his hips, “Remus…”

           “Yes, Logan?”

           Logan cleared his throat, “I’d like to… inquire about your extra… appendages.”

           “Logan are you asking to see my cock?”

           ”NO!” Logan calmed himself with a breath. “No… I’m asking about the tentacles.”

           Remus giggled, “Well they love attention almost as much as I do. Should we go off to your little lab?”

           “Oh, no this is fine,” Logan said. “If you feel comf-“

           Remus was already naked with the wave of his hand, and he held his hands out like a circus ringmaster as the tentacles sprouted from his back and began to slide over his body. He held Logan’s gaze, lifting one hand to beckon him closer, “Come on.”

           Logan stepped forward, eyes glued on the nearest green entity as it lifted away from Remus’ chest and moved to meet Logan. Logan lifted his hand slowly and touched the tip. It was smooth, slick and surprisingly warm; it shivered lightly under his touch and Remus’ face shifted. The tentacle nuzzled against Logan’s palm and up to wrap around his wrist, leaving a clear trail in its wake, “What is this substance?”

           Remus shrugged, “No idea! I use it for lube.”

           Logan’s cheeks colored but he kept his eyes on the tentacle as it worked up his arm; in his pants, an uncomfortable tightness was forming, and he shifted, trying to ignore it in favor of continuing his exploration.

           “Do you like it?” Remus asked, smirking.

           Logan nodded, adjusting his glasses with his free hand, “Yes. They’re… fascinating. What… can they do?”

           Remus grinned, all teeth, “Now you’re speaking my language now. Why don’t you take off your clothes and I’ll show you.”

           Logan blinked, but it was an easy decision, losing his clothes in exchange for a continued experience. He undressed methodically, leaving Remus a bit impatient, but when he was down to his glasses, Remus was smitten. The chaotic side moved to his bed, stretching out on his back. “Come over here, Moonbeam, make yourself comfortable.”

           Logan hesitated, but he crawled up onto the bed and Remus helped him into place. Logan straddled Remus’ thighs, the blush on his face spreading over his body, “Is this-?”

           “Perfect,” Remus purred. “Now just hold still and let them feel you.”

           Logan stiffened when the first tentacles touched him, sliding up his legs to his hips, his waist, his chest. One particularly curious appendage came close to his face, bumping against his lips. Logan raised an eyebrow, glancing down at Remus before the tentacle repeated itself more insistently. Logan parted his lips to comment, but the tentacle slid between them and pinned his tongue down. Logan lifted a hand and the tentacle quickly retracted, “That was…”

           “They get a little friendly,” Remus said. “Too much?”

           Logan looked down, where the tentacles were wrapping around his legs and waist, up his back to cradle him. They avoided his twitching cock, and Logan was too fascinated to be embarrassed about his own body’s reactions. “No… no it wasn’t too much.”

           Remus slid his hands behind his head, reclining as he watched the tentacles manhandling the other side. “Tell you what, why don’t you keep your hands to your sides, making a fist. If you need a break, just open your fist.”

           “That seems reasonable,” Logan said, and when the tentacle returned he opened his mouth a bit wider for it, happily inviting it back in.

           Remus’ own cock twitched as he watched the logical side, all wrapped up in him, taking a tentacle into his mouth—and he appeared to be loving it. Much more than Deceit who usually spent the experience rolling his eyes and muttering catty insults around anything Remus put in his mouth. Logan was so much more fun. Realizing he was literally daydreaming through an actual fantasy, Remus snapped out of his thoughts and looked back up to the scene unfolding above him.

           Logan’s head lolled back and the tentacle pressed further, bulging his throat in a slow, tantalizing wave as Remus watched. The logical side made soft noises of discomfort, but his hands staid curled at his sides. Remus reached with a smaller tentacle and delicately plucked his glasses from his face as tears began to slide across his cheeks, setting them aside. Remus wasn’t actually an animal, after all; he could be thoughtful. Logan’s left hand spasmed, opening and closing, and Remus caught it instantly; the tentacle retreated—still poised over Logan’s red, slippery lips—so Logan could breathe, and he did so in greedy, rasping gasps. Remus watched him with careful eyes, almost losing it when Logan opened his mouth and let his tongue loll out, asking—begging—for more. Remus grit his teeth and watched the tentacle breach Logan’s mouth once more, earning a muffled moan that quickly devolved into a soft guttural choking sound. Remus might actually be in love.

             When he pulled the tentacle from Logan’s mouth with a loud, wet pop, Logan looked down and seemed disappointed; the tentacle wrapped loosely around his neck, not interested in straying too far. “I thought we’d do something a little more-“

“There’s more?” Logan breathed.

Remus practically cackled as he sat up slightly, the tentacles holding Logan in place, “Oh Moonbeam I am going to change your life. Have you heard of sounding?”

“You mean Depth Sounding? I have, Did you know famous author Mark Twain took his pen name from a common term in Depth Sounding, by the mark of twain. It means-“

“I do not mean Depth Sounding,” Remus said. “Well… not exactly. You’re going to enjoy this a lot more than… whatever that was.”

“D-“

“Ah!” Remus scolded, holding up one finger. Logan fell silent, watching him with sullen curiosity. “There’s a good boy. Now just hold still, and remember your signal.”

           Logan nodded, positioning his hands back at his sides. Remus sent out another tentacle; it traveled down his body and onto Logan’s, sliding up his thigh. Logan watched the thin tentacle snake around his cock, coiling around the head and spreading a thick layer of its shimmering slick. The tip was small, four—maybe five—millimeters in diameter, and Logan felt that delicious pang of nervousness when it first nudged at his slit. He exhaled as the tentacle entered him, a fullness that was just shy of unpleasant. Logan let out an open-mouthed groan, but his eyes were locked on the tentacle that slowly disappeared into him, wincing when it came against a stronger resistance. Remus reached down and repositioned Logan’s cock. “Relax,” he purred.

           Logan did and with a pop that he felt without hearing, it went further, and the unpleasant pressure gave way to a deep, unattainable stimulation and made Logan grab Remus’ wrist and shake, “Remus! I-“

           “Shhh I know,” Remus cooed, leaning in to kiss him. “I know Moonbeam. Let them be sweet to you. Just relax.”

           Logan swallowed and took a deep breath, letting his hand go back to his side and curl into a fist. His thighs tensed around Remus’ thighs when the tentacle began to move, first subtle little writhing and then a slow, slippery in and out that made Logan whimper, but it was good, so good. Remus bit his bottom lip, “Ready for more?”

           Logan opened his eyes, and looked down at Remus, “I don’t think I can take another-“

           “Not there,” Remus said, and one of the tentacles that had been holding Logan’s thighs slid up and around the logical side’s ass.

           The other tentacles spread Logan’s thighs just a bit, and the one around his throat pulled gently, leaning him forward. Logan exhaled, “Yes… please.”

           The first tentacle made Logan hiss. It was cold, comparatively, and the stretch and burn while fascinating—and pleasurable—were undeniably new. Everything was slow, tentative, the tentacle inside Logan’s cock had gone still, letting each sensation come independently. When the stretch had sloped down to a thick, pleasant slide, Logan whined, “What’s the matter, Moonbeam?”

           “M-more,” Logan gasped. “More please.”

           “Greedy greedy,” Remus said, but he obliged, and soon another tentacle was teasing at Logan’s entrance, making the logical side’s breath catch in his throat. The first tentacle had found his prostate, and Logan let out a yelp of surprised pleasure, his head falling forward and his disheveled hair obscuring his eyes. Remus moaned and nudged Logan, “Sit up, arch your back.”

           Logan muttered a half-hearted complaint but he did as he was told, rebalancing his body; his head went back this time, his body drawn out like a piano wire. Remus took in the gorgeous sight as the tentacles inside moved, all at once, writhing and pushing and caressing. Logan mewled, and his eyes opened; he looked at Remus for one moment before he visually noticed the tentacles moving inside of him, two eager bulges under his skin. Logan’s mouth fell open and Remus took his hand, pressing it to the spot. “Doesn’t it feel good, Moonbeam? All filled up with me? Letting me explore you.”

           Logan panted, unable to form anything coherent; his head fell back and he opened his mouth. There was that tongue again, and Remus could have cum just from the sight—and the thought—of four tentacles driving into his new bedfellow. Logan, Logic, stiff, stick-in-the-mud, no-nonsense Logan was a trembling sobbing mess, being sounded and throat fucked and double penetrated by the very agent of entropy and decadence. It was poetic, in theory and in practice, and Remus allowed himself a self-indulgent moan as he returned his focus on disassembling his little android. The tentacles attacked Logan’s prostate from both sides, and Logan choked on the one down his throat, letting out a garbled little moan as the appendage pulled back, drool and slick rolling down Logan’s chin onto his heaving chest. He panted in a deep, rugged, ruined voice before opening his wide mouth again, silently begging.

           Remus left him waiting for a moment, drooling and heaving, “Look at you, Pavlov’s Slut, how cute.”

           The teasing and moaning tapered off then, and Remus focused his efforts. Soon Logan’s entire body was tensing and quivering in a rapidly deteriorating rhythm, his untouched cock twitching and jumping with even the tiniest movements of Remus’ tentacles. The climax rolled through him like an avalanche; Logan choked on the tentacle in his mouth but his hands stayed curled into fists as pleasure tore through him, deep, hard and dry. Remus’ expression turned feral at the promise of making Logan cum again without employing any of his usual magic. He pushed Logan through the dry orgasm, drawing it out until Logan was whimpering and squirming. Then, Remus let go, the tentacles holding Logan upright moved away and he fell onto his back, the tentacle leaving his mouth. He panted and sputtered and sobbed. The two tentacles abandoned their assault of Logan’s insides until all that was left was the tentacle he’d been using to sound Logan’s brains out. As it retracted, Logan arched and shouted, surprised and probably a little frightened by the intensity of the orgasm that ripped through him. Remus moved away as Logan came, painting his stomach, thighs and the dark sheets beneath him. He was a trembling, writhing mess, and Remus couldn’t help but smiled fondly, “My, I’ve made a mess.”

           Remus moved back in, reaching to stroke Logan’s hair, but the other side caught his wrist, pushing him away. He sat up, waving his hand to clean up the sheets—and himself, “Thank you Remus.” His voice was hoarse, shaky, weak, and  when he tried to stand he instantly collapsed. Remus caught him, but Logan pulled himself together—and away—and picked up his glasses from the nightstand.

           “You know, it’s customary to engage in some after care after this kind of-“

           “Thank you, again, but I won’t be needing that,” Logan said, his tone even and pleasant. He used his magic to dress, and left the room on shaky legs.

           Remus watched him go and tried not to be insulted.

Never Seen That Color Blue by Kerasines

Chapter 1 | E | Harringrove

Billy doesn’t want to think it, but Steve goes ahead and says it anyway. “A tentacle.”

He looks as apprehensive as Billy feels at the thought of a fucking tentacle being attached to Billy’s body in any way, let alone spontaneously growing out of his back. Jesus, what the fuck. But it’s undeniable that that’s what it looked like. What it felt like.

“Fuck you. Christ. What the fuck.” Billy rubs his eyes until he sees stars.

Tentacletober Day 3: Injured Tentacles

@lynne-monstr

Tentacletober prompt 5: First Time 

 ao3 link 

“Alexander,” Magnus breathed out and by Edom, the sight of his fiancé was like an ethereal balm to his lonely eyes.  For a moment he worried that perhaps Lilith had created a mockery of what he wanted most, to taunt him with. Then hot, dusty hands were pulling him into an embrace and he could smell the familiar scent of their shared sandalwood shampoo and the salt of Alec’s skin underneath the layers of ichor and dust.  

No dream could feel as sweet as the press of Alec’s chapped lips brushing against his own.  

He was dirty, exhausted and so very beautiful in Magnus’ eyes.

Around him, his new reality flickered and he brought his powers up sharply, desperate to reign them in as he heard footsteps.  Now was not the time to introduce Alec to the unexpected turn Magnus’ victory had taken.  

“I”ll stay here, with you.  I’m never leaving you again.”  Alec promised and Magnus knew he was sincere but he also knew that his fiancé was unaware of certain changes.  Magnus adored Alexander, so did his magic and that meant that his new appendages wanted to understand why all of Magnus adored him so.   

“Alexander,” Magnus murmured, “before you say such things.  I need to tell y-“

Magnus blinked once before narrowing his eyes as Lorenzo unexpectedly entered the room, interrupting him and his tentacles bristled.  They were already irritated at being glamoured and kept from Alec and at the moment they were completely in-tune with his feelings which meant they had a new target for their ire.  Magnus used every bit of his self-control and tightened the glamour restraining them, now was not the time to socialize his tentacles.

“What was it you wanted to tell me?”  Alec asked once they were alone and in the safety of what was once again -finally - their loft.  There was a soft smile on his face as he kissed Magnus’ cheek and Magnus wanted to bask in the feeling of him being near, of being with Alec but he also knew that it was time to share with him the truth.

One of Magnus’ tentacles reached out to gently trace Alexander’s deflect rune.  Alec twitched, hand coming up to automatically bat the unexpected touch away and then he froze when his wrist was grabbed by a different, more confident tentacle that gently but firmly held him in place.

“Wha-?”  He started to ask and then he went quiet, a soft and startled sort of silent as he turned wide, confused eyes to Magnus.

“It just so happens,” Magnus said and gave a small and fragile smile, “that defeating my father came with both perks and… shall we say disadvantages ?” 

One of his tentacles smacked him and he shushed it, casually pushing it away from him with two fingers. 

“Magnus?”  Alec asked warily, “please tell me it’s your magic currently giving my neck a hickey and holding my wrist.”

“Not my magic technically ,” Magnus hedged and then hurried when Alec’s face darkened, “but a part of me nonetheless.” 

“So what is it?”  Alec asked and his voice got a little higher at the end, his chin lifting up as a slightly overeager tentacle latched another sucker to his skin.

“Well,” Magnus started and paused as his normally silver tongue fumbled for the right words, “you won’t have a reason to complain about not getting enough cuddles.”  He offered and then slowly let his glamour rescind.  

Alec caught his gaze first.  The look of adoration that filled his eyes upon meeting Magnus’ own un-glamoured ones was blinding and Magnus could see how his pupils widened and the corners of his eyes crinkled.  It also meant that Magnus could tell the exact moment Alec saw his new appendages. 

 There was a murmur of discontent in Magnus’ emotions when Alec’s eyes narrowed in confusion and Magnus couldn’t control how his tentacles reacted to it with a frisson of chaotic, restless energy.  One even went so far as to knock a vase off the table but before Magnus could use magic to catch it, another had swept it up and put it back. Magnus mentally sighed and hoped that this wasn’t an indication his tentacles were going to be the equivalent of numerous, wriggling and impulsive cats.   

“I- thats… definitely new.”  Alec said and Magnus was determined not to let the reaction disappoint him.  His tentacles and subconscious had a different opinion it seemed and the tentacle wrapped around Alec’s wrist pulled him towards them with a stubborn intensity.  

“They think rather highly of you,” Magnus told Alec when he was only a step away and even as he said it, he knew that it was an understatement.  If anything, he could feel a thrum of insecurity that was a little foreign, as though his tentacles were desperate for Alec’s validation and affection.  

“Oh?”  

“Yes, I’d say they’re almost-“ and as Magnus paused, the ones that had been waiting moved in, pressing up against Alec’s spine until he was nearly flush against Magnus chest.  “Impatient,” he finished and smiled when Alec only managed a breathy chuckle. The fact that they had integrated with him but not completely worried Magnus sometimes, but he did feel some relief at how much they seemed to adore Alec.

“They are very friendly,” Alec said, “and now that I know they’re yours, I’ll figure out how to work with them.  I love you Magnus, every part of you.  There could never be anything ugly about you, ever."

One, very helpful tentacle curled through Alec’s belt-loops and pulled him even closer so that Magnus could kiss him.  Because kissing Alexander felt both like coming home and feeling whole again all at once.

Alec’s fingers dug into his hips, hard enough to leave bruises and his breath stuttered as Magnus tangled his fingers into Alec’s hair.  Magnus wanted more, he wanted Alec under him and over him, pressed against him and with Magnus’ magic flooding him like they hadn’t in what felt like a lifetime.  

He wanted to relearn how Alec felt, taste and touch him with his magic and his lips and feel the adoration and devote sincerity of Alec’s affections through his magic and reactions.  There was another gasp, a little sharper this time and when Alec moved away, Magnus followed, chasing the taste of his lips.

“Magnus,” was murmured against his lips and he paused, his fervor dampened by the grip on his arm even as Alec’s chest heaved against him.

“Alexander?”  He asked and pressed his lips to Alec’s neck, licked away the salt from the rune there and cherished the shudder it earned him.

“Your uh- you, what are- are they?”

And Magnus realized what had Alec in a confused, distracted haze.  The tentacle that had so helpfully curled in Alec’s belt loops and pulled him close, had unbuttoned his pants and was teasing him slowly.  Pulling back a little further, Magnus surveyed the willing mess his tentacles were making of his fiancé.

The tentacle at his neck had left deep, red marks that could easily pass as hickey’s but would far less easily be hidden from view without magical aid.  It had then circled around to let Magnus press his own arduous kiss to Alec's skin and was now leaving similar marks down Alec’s collarbone and past the v of his shirt.  

“They have priorities."

“And what priorities are those?”  Alec asked, breathless and adoring as he caught Magnus in another kiss.

“To learn you, to memorize you.  To love every part of you,” Magnus murmured quietly against Alec’s lips.

"Those are good priorities," Alec agreed breathlessly and the confirmation sparked a heat deep inside of Magnus, an eagerness to pull more noises and .

-

It was late and despite how tired he was and how bone-achingly sated he felt, Magnus couldn’t settle, his magic and tentacles restless as they moved about him.  Doing everything from smoothing the silk sheets on the bed to running through Alec’s sweat-damp hair and pressing sucking marks against the sensitive skin along his spine.

“What do they want now?”  Alec asked, voice hoarse from sleep and with a rasping tinge that spoke of deep exhaustion.  Magnus didn’t even need to scold his tentacles, they seemed to understand that they’d woken up Alec and he could practically feel their guilt.  

“Nothing love,” Magnus murmured and ran his thumb over Alec’s cheek, “that was my fault.  I’m still trying to figure out how to work them.”

Alec didn’t say anything else, just nuzzled against Magnus’ palm and pressing a kiss to the skin there before closing his eyes and sinking back into the pillows.  

His tentacles bristled with indignation and Magnus could feel his warring emotions swell.  First there was contentment, that Alec was settling back down and at the same time, dissatisfaction that Alec wasn’t showing the same amount of care to them.

Magnus sighed, a headache starting to build and a tentacle helpfully moved up to pinch the bridge of his nose.  The others guiltily tried to relax but Magnus was about to give up on sleeping at all. In Edom, he had considered them an extra security measure while vulnerable but now, here safe in his bed with Alec, they were a nuisance and even as tired as Magnus was they felt no closer to calming down.

“Babe?”  Alec asked and the rare nickname made something raw and tender in Magnus’ chest throb, “what’s wrong?”

“Just,” and Magnus paused, unable to articulate that his frustration wasn’t so much with his tentacles as much as how much his tentacles felt… emotionally.  

It was one thing to learn how to regulate the sensations and physical synapsis of added physical and magical appendages.  It was quite another to suddenly have to also deal with an unregulated emotional onslaught and energy.

“They’re just sensitive,” he finally said, hating the choice of words, “a little uh, tender right now.”

There was a moment where he thought he’d managed and then a deep, sleepy chuckle, “they’re lonely, aren’t they?”

“Something like that,” Magnus admitted.  “It’s all very new. I was just learning how to manage them when you showed up and now-“  He would never complain about Alec having come for him, or be upset with how quickly his tentacles had become besotted.  He’d even suspected it would happen, what with how much his magic had always loved Alexander and how it had thrummed in his veins when they’d been reunited.  However, there was something to be said with timing and his tentacles didn’t seem to understand that Alec was still adjusting to their presence.

“C’me here?”  Alec asked and Magnus settled back down, careful not to press too close least his tentacle get any ideas.  “Magnus,” Alec complained, “please. I missed you, I can’t be in the same bed as you and not have you as close as possible.”  

There was a desperation in his voice and Magnus could no sooner hear it than not do everything and anything in his power to alleviate it.

“I missed you too,” he said, “so much Alexander.”  

“I don’t mind them I promise, just please.  Hold me?”

His tentacles didn’t pounce, nothing so undignified as that, but they surrounded Alec without hesitation.  It was as though they were worried he’d rescind the invitation and were desperate to claim a place for themselves.  Magnus curled an arm tight around Alec’s back, pulling him closer still and Alec pressed his nose to the crook of Magnus’ neck.

“They’re nice like this,” Alec finally said, lips brushing against his skin and all of Magnus shared a feeling of deep relief, “it’s like a giant hug.”

The tentacles squirmed happily about Alec even tighter, careful not to hurt him but holding him as close as possible and finally, Magnus felt like he could sleep.

You complete me

Summary: “Why are you so… sparkling?” Alec sighs while poking at his odd tentacle. His tentacles are mostly navy blue with black linings, except his soulmate mark – a bold and dashingly gold, sparkling as if it was dipped into a bucket of glitter.

His golden tentacle snaps at his finger, seeming offended by Alexander’s tone. He rolls his eyes, but his lips curve a little bit at the corners. So dramatic for a tentacle. Then, it curves around his wrist and wiggles slightly, a gesture it loves to do every time it has a chance. 

Pairing: Magnus Bane/Alexander Lightwood

Miss @lynne-monstr won me over with all the tentacles stories and I gave it a shot. Uh... I don't know if it's good, but I hope you like it? And I hope the explanation of the soulmate marks isn't confusing...

You can also read here: ao3

_______________________________________

True love irradiates color, thus each soul reverberates with a specific one to find its equal.

Everyone is born with semi-sentient tentacles which only manifests after their 10th anniversary if they have angel or demonic blood. Vampires and werewolves will manifest them one week after being turned. Being the mirror of the soul, their color varies from person to person. All tentacles will share the same color, except one – this one will have the color of the person’s soulmate’s tentacles. When these special tentacles from two soulmates touch each other, their color swaps as if returning to their original owner.

Thus, if a person has all tentacles with the same color it means they’ve already found their soulmate.

Mostly, people keep their tentacles glamoured, but being semi-sentient they dare to expand sometimes and touch other people’s tentacles in hopes to find their mate.

“Why are you so… sparkling?” Alec sighs while poking at his odd tentacle. His tentacles are mostly navy blue with black linings, except his soulmate mark – a bold and dashingly gold, sparkling as if it was dipped into a bucket of glitter. He doesn’t hate that color, just… think it is awkward. It isn’t a common one, especially for Shadowhunters. Usually, they have more dark colors, with one or another exception. He has to keep them glamoured more often than his peers, even inside the Institute. He doesn’t want more reasons for judging eyes and scornful comments.

His golden tentacle snaps at his finger, seeming offended by Alexander’s tone. He rolls his eyes, but his lips curve a little bit at the corners. So dramatic for a tentacle. Then, it curves around his wrist and wiggles slightly, a gesture it loves to do every time it has a chance.

Alec doesn’t know who his soulmate is, but he already loves him. Yeah, he knows it’s going to be a man, he’s already made peace with his sexuality, even though only his siblings know the truth. And if this man is as sweet as his golden tentacle, Alec isn’t afraid of the future.

About his siblings, they are lucky. They’ve already found their soulmates. Now, Jace has a full set of beautiful onyx tentacles which paired with the copper ones from Clary, a hurricane that stormed into their lives two weeks ago and already gave more headaches to Alec than he has felt in his entire life. And Izzy has rouge tentacles which paired with cerulean ones from Simon, Clary’s best friend and ex-mundane. His sister only found her soulmate because he was turned into a Vampire, and this kind of fate is terrifying to think about. At least, they are happy now.

Alec sometimes thinks if he is going to find his one day. It seems unlikely, he isn’t so lucky like his siblings.

Sometimes it’s better to accept you will never have what you want.

“Stay for just one more drink and then decide.” Magnus offers a Martini again and Alec is too speechless to say no. He has to go back to the Institute, but can’t make his legs move. Just a simple movement yet he forgot how to walk.

And then it happens.

Three tentacles poke behind Magnus, moving smoothly as if they are curious about something. It wouldn’t be a surprise if they weren’t gold.

Really sparkling and glittering gold.

“Ma… Magnus.” Alec stutters, five shades paler. “Your… Your… They…”

“Oh,” Magnus takes a full minute to understand Alec, but when he does, he grins. “I guess they were bored. Or maybe just as interested in you as I am.”

Alexander feels light-headed. His hands tremble a bit, but he braces himself.

“Your soulmate mark. Which color is it?” He doesn’t want to sound so demanding and curses himself for asking that out of the blue. It isn’t polite. Nobody goes out asking the color of one’s soulmate mark.

But he panics, and the thrills of the possible answer make his heart pounds hard.

“Well, this is unexpected.” Magnus frowns, a bit dumbfounded. “I was hoping we could have at least some dates before getting this intimate, but you seem to surprise me every time, Alexander.” He licks his bottom lip, feeling the strong taste of alcohol. And, as a cue, a navy blue tentacle wiggles behind the Warlock.

Alec’s brain freezes for a split second and the glass he is holding slips from his fingers. However, before Magnus could react and use his magic to hold it in-middle air, all of Alec’s tentacles burst unglamoured trying to reach the glass.

Just one, though, holds it.

His golden one.

At that, even Magnus freezes for a moment. Soon, something brightens his eyes and a small but adorable smile draws on his face. His navy blue tentacle reaches for Alec’s golden one and they finally touch each other. Almost instantly their colors swap as if one tentacle had absorbed the other.

A sense of wholeness fills both Warlock and Shadowhunter, yet doubled. They feel like a piece of themselves is finally back, with something extra. Something they’ve been craving, and now everything makes sense.

Their – once – different tentacles are still touching each other, and soon others do the same.

Then, Alec decides two things: First, he is almost sure gold will become his favorite color really soon. Second…

“I believe I have time for one more drink,” or ten. He tries to suppress a smile, failing miserably. “I can go back to the Institute later.”

And then he doesn’t.
