(Before we begin, this fic is inspired by this art by cam-ryt on tumblr. All the outfits Alec wears in this fic are from that art.)

Magnus scanned the club from the balcony, taking in all of the patrons. Most of them were regulars, faeries and vampires he would see maybe at least once a week when he came down and who knew him as well and who knew not to cross him. Newcomers could sometimes be a handful, but the warlock has always been good at bringing the point across that he tolerates no bullshit in his club.

Just as he was thinking that, his eyes landed on a newcomer. Magnus could tell the person had never been there by the way he was moving, unsure where to go and what he would find there. And there was also all the Runes on his body that were hard to miss since the warlock sure didn’t have any Shadowhunter regulars.

But only a moment later did Magnus realize how much skin covered in Runes he could actually see. The Shadowhunter was wearing a lot but almost nothing at the same time. He caught eye of a beige skirt that barely covered anything and a grey cropped sweater that only reached just above the man’s ribs. This was...different. It was rare he saw a Shadowhunter in anything another than black, but this...this was something else.

So naturally, Magnus started walking down the stairs towards the dancefloor and towards the man. He liked to get to know new patrons. Well, this specific patron he would love to get to know a lot better.

He navigated through the crowd, greeting people where appropriate. His acquaintances seemed to take notice of the fact that Magnus had his eyes fixed on someone and that he was heading in one specific direction because they didn’t try to make any conversation.

However, the man who had caught Magnus’s attention had yet to observe him. The Shadowhunter sat down at the bar, ordering a drink for himself and he was currently waiting for it to be made when Magnus sat in the vacant stool next to him. He felt the Shadowhunter’s eyes on him, taking him in for a moment and Magnus just looked at the bartender, trying to seem nonchalant.

The barkeeper turned around with a tall glass that he handed to the Shadowhunter and before he could speak, Magnus did. “That’s on me. Can I get a Martini please, Tom?” he asked, and Thomas didn’t question it and just got back to work.

He could feel the Shadowhunter’s eyes still on him, so Magnus finally turned towards him, taking him in. That outfit looked even more sinful up close and though Magnus had seen his fair share of outfits like that in his lifetime, the man wearing it was really the star of the show, his body all sharp angles and well tones muscles and, in contrast, a waist so small that shouldn’t have fit perfectly with the rest of him, but it did. When when Magnus was done checking him out, he looked up at the man’s eyes and saw the most striking shade of blue.

The Shadowhunter seemed amused by Magnus shamelessly checking him out and he looked back at him with a playful glint in his eyes. “Thanks,” he simply said, holding up his drink and taking a sip, eyes fixed on Magnus.

“My pleasure. I couldn’t let a pretty thing like you drink alone,” Magnus said in return, and he was quite thrilled when he saw a blush creep on the man’s face. For someone confident enough to walk into a club wearing that, he seemed to be pretty easy to fluster. Magnus loved that.

The bartender set down a Martini in front of him and Magnus picked up his glass, holding it up and turning to the man again. “To us,” he said, but then found himself frowning when he realized the man’s eyes were not on him anymore, but he was scanning the room instead. Magnus suddenly came to the realization that as much as the man’s outfit was anything but Shadowhunter gear, he was probably there on a mission. It was always like that with those Nephilim

The stranger seemed to spot whoever he was looking for, because he picked up his drink and hopped off the stool. “Thanks for the drink again. Duty calls. But who knows… maybe next time you buy me a drink I might tell you my name,” he said, making his way to the dancefloor without another word. Magnus wished he could say that he didn’t stare at the man’s ass as he walked away, but that would be a blatant lie.

Magnus’s eyes followed the stranger as he approached a vampire on the dance floor. The Nephilim started dancing his way towards him and once he was in front of the vampire, the Shadowhunter put his arms around the vampire’s shoulder, and they started dancing suggestively. Magnus wasn’t sure he would call that dancing, from his point of view they seemed to be totally out of rhythm with the music, but that didn’t seem to bother them.

He was about to look away when he caught sight of the Shadowhunter’s face over the vampire’s shoulder. He was whispering something in the vampire’s ear, but at the same time, his eyes were on Magnus and then he did something that he probably knew would totally make Magnus look for him again. He winked.

“Well, I’ll be damned,” Magnus muttered, downing his drink in one go.

Magnus really didn’t want to look for the Shadowhunter the next time he went to the club because he didn’t do “being hung up on someone”. That is just not how he rolled, especially not for someone whose name he didn’t even know. However, he couldn’t deny that there was something entrancing about that specific man and how much he seemed like a Shadowhunter while at the same time he seemed like something else. It just made Magnus want to learn more.

He wasn’t surprised the Shadowhunter wasn’t there when he went there the next day. Shadowhunters were often on tight schedules and Magnus couldn’t imagine anything more horrible than having to be on patrol for most of your day just running around the city. Thank goodness for Portals.

However, just a week after their first meeting, Magnus found himself in the club again. He was wearing his best purple velvet suit because he was always dressed to impress and this was his club after all so he couldn’t possibly show up looking like he didn’t put any effort into his outfit. He was nurturing a Margarita and making small talk with some people passing by when he saw someone sit down next to him out of the corner of his eye.

All he could see at first was a flash of pink and when he turned around, he was surprised to see the Shadowhunter that had been occupying his mind way more than he liked to admit right there next to him. His outfit didn’t disappoint either and if anything, it left Magnus even more speechless than the first one. It seemed to be a school uniform inspired outfit with another short skirt, this one grey with pink stripes and a belt holding it up around his waist. It was paired with a shirt that was a matching color and a combination between a white button down and a sweater, reaching just below the man’s chest. The sweater had the word “pup” written in bold pink letters on it.

Magnus was just mildly surprised that the stranger sat next to him by his own accord, but he guessed that wink the Shadowhunter gave him the previous time they’d met meant something.

The warlock smiled at him coyly. “Hello there, beautiful. What would you like to drink?” he asked, remembering their conversation about buying a drink and getting his name. It seemed like a fair trade.

The Shadowhunter smirked, probably thinking the same thing, and then turned to the bartender. “I’ll have a Sex on the Beach please,” he asked politely and then turned to Magnus again. “Have you been looking for me?” He asked nonchalantly.

Magus was taken aback by the confidence, but he welcomed it anyway. “You did leave quite the impression, Shadowhunter,” he muttered, then picked up his drink and took a sip. He looked over the rim of his glass at the man in front of him and raised an eyebrow. “Besides, you know that vampire you were dancing with, Robin? I heard someone from his clan got arrested by the Clave a few nights ago,” he added. Because while Magnus couldn’t deny being fascinated by the Shadowhunter, he didn’t like it when the Clave was doing its biddings inside his club.

The Shadowhunter played dumb and pretended not to see the connection. “Oh, a coincidence. What a shame, he was a mediocre dancer,” he muttered and thanked the bartender as he passed him his cocktail.

Now Magnus was starting to get a bit irritated though, because his club was supposed to be a safe space for Downworlders and not even a cute Shadowhunter could compel him to bend his morals regarding that matter. “Let me make this clear, Shadowhunter. If you are a mole for the Clave, you are not welcome in my club. People are here to feel good and not to feel like they are watched.”

“Alec,” the other man spoke, unbothered.

Magnus frowned. “What?”

“I am a man of my word. You bought me a drink. My name is Alec,” The Shadowhunter said, voice more serious than Magnus had heard him yet. “And I don’t know if my ‘gear’ didn’t make it clear, but I am not here on official Clave business.”

Alec. Magnus tried to think if he knew anything from the New York Institute with that name at one point but came up blank. However, this was not his priority either. “So what business are you here on, Alec?”

Alec shrugged. “Oh well, I am an informant. But not by the Clave standards, by my own. I know that the Clave tends to prosecute Downworlders unfairly sometimes, so I truly look into my cases before acting on them. Of course, we get unfair orders from the Clave, but I never go undercover for those ones, they are not worth the energy. But I use my skills of getting information out of people for the cases that I consider fair. The vampire that got taken by the Clave turned a mundane and then proceeded to kill them when they became a vampire to hide their tracks,” he explained matter-of-factly.

And Magnus didn’t want to believe that explanation because it seemed too simple. But then he looked at Alec’s outfit again and figured that Alec probably didn’t report everything about his mission and his source back to the Clave. The Clave was made up of old Conservative people so yeah, maybe they were on the same team.

“Okay, so say I believe that. Who is your target tonight?” Magnus asked curiously.

Then for the first time Alec turned around to look out at the room and tilted his head towards a corner where a group of people was standing. “The one in the blue shirt. His name is Ben, he is a werewolf, and he is seeing this faerie who has been selling Seelie drugs to mundanes in Central Park. I am just trying to get some intel on when the next deal will go down so we can interfere with that before a mundane gets hurt,” Alec explained and Magnus wondered why he was giving away all the details about his mission to him.

But what struck him even more about this is the fact that Alec’s target was a werewolf. He looked down at Alec’s shirt and laughed out loud. “’Pup’? Isn’t that a bit much to flirt with a werewolf?” He asked, amused by the attempt.

Alec looked back at him and smiled smugly. “People looove stuff that is a bit much, makes it more of a challenge to them,” he said confidently and something about the way he talked made Magnus find him even more attractive. Maybe it was because Alec said people instead of Downworlders, which is what Magnus was used to hear from Shadowhunters. The Nephilim always loved to single them out, making it seem like everything sinful or inappropriate was tied to their demon blood. Even if he didn’t have demon blood, Magnus was pretty sure he would still be into the sinful and inappropriate stuff, thank you very much.

The warlock could see that Alec was eyeing his subject intensively now and thought he was about to move in, so he asked him one last question. “The stuff you wear…is it all just part of your mission persona?” He was pretty sure that by the way Alec was moving so confidently in those clothes he didn’t just do it for the show, but he found it interesting to ask.

At that, Alec started blushing again just like he had done the first night when Magnus called him pretty. “Actually, I pick all my outfits from my own wardrobe so…yeah, make of that what you will,” he simply said, getting down from the stool and straightening up his skirt before giving Magnus one look and a wink. “See you next time, Sir,” he said teasingly, and damn Magnus didn’t have a Sir kink, but he was pretty sure that someone with a face and a body like Alec could call him anything and it would become a new kink.

“Looking forward to it, Alec,” Magnus replied, watching as the man made his way through the crowd to the werewolf he targeted.

So much time had passed between the second and the third time Magnus saw Alec in his club that he was not even sure he would see him again. Granted, Magnus had had a lot on his plate as well, with rumors of Valentine returning and the Circle regaining numbers and power. Magnus tried his best to keep his closest friends and as many warlocks as he could safe and alive by helping them with their wards and he trusted his friends to keep themselves safe too. However, he still wanted to drop by Pandemonium every now and again just to make sure the Circle wasn’t creating any problems there, as he had already come across some members that he quickly got rid of with a warning.

Tonight was one of those nights where he wanted to drop in at the club. For now, Valentine didn’t seem to want to make a personal appearance, as if he was waiting for something. What for exactly, the warlock didn’t know, but Valentine couldn’t stop Magnus from having a good time. And he put on an outfit for a good time as well, even dyed his hair a dark green at the tips because it matched his make-up. Other than that, he was wearing black glittery silk top with a deep V-neck cut and some dark green slacks that made his ass look great if he said so himself.

And he was even more glad he came down when he saw a familiar face in the crowd. It was harder to find Alec this time because he was standing right next to the dancefloor instead of at the bar, but Magnus made his way to him, nonetheless, buzzing for a distraction. He’s been meaning to get his hands on that specific distraction for a longer time than he liked to admit now.

“Alexander,” he greeted as he approached the Shadowhunter and the other man looked at him with confusion in his eyes. Of course Magnus wasn’t stupid and he had gone looking to see who this Alec guy was. And he stumbled upon one person working at the New York Institute known under Alec and that was none other than Alexander Lightwood. To say that Magnus was mildly surprised was an understatement. He knew Robert and Maryse Lightwood and he knew how much Alec must have been keeping his mission on the down low because the Lightwoods were an old family that followed the old ways.

He took in the man’s appearance from up close and had to stop for a moment. Because this outfit Alec was wearing tonight was covering more skin than the others, but it also seemed the most sinful of them all. It was simple and maybe the simplicity of it was the beautiful thing because it made Alec’s body stand out. He had a pink cropped hoodie, a black skirt that was longer than the ones before but just short enough to drive Magnus insane. But the best part (or the worst part for Magnus’s sanity) were the fishnets that he was wearing under the skirt.

Magnus was just staring at him openly and didn’t even realize the Shadowhunter had said something to him. Alec snapped his fingers in front of him and that seemed to do the trick because Magnus snapped out of his daze. “What were you saying?” he asked, not even bothering to seem ashamed because he was staring.

Alec didn’t seem annoyed to repeat himself. He seemed more pleased at Magnus’s reaction to his outfit. “I asked if you would like to dance,” he said, putting a hand on Magnus’s shoulder tentatively.

And Magnus was a weak man and , as he had just found out, an even weaker man when it came to one Alexander Lightwood in fishnets, so he just nodded and let Alec guide him to the dancefloor.

It seemed like the Shadowhunter was taking his time tonight and Magnus wondered whether he was off duty and just there to have fun. In which case Magnus would be relieved because at least he would know for sure he hadn’t imagined that tension between the two of them.

Once they found a free spot on the dancefloor -it was Friday, a busy night so everyone was somehow huddled together – Alec put his arms around Magnus’s shoulders and pulled him so close that their bodies were pressed against each other. Magnus put his hands on Alec’s waist and quickly noticed how tiny the man’s waist was in contrast to the rest of his toned body. It was doing things to Magnus.

The warlock put his chin on Alec’s shoulder, leaning in to speak in his ear while they started swaying to a random song. “So what brings you here tonight, Shadowhunter?” He asked, not letting it show that he was hoping for a specific answer.

“I’m still on duty, if that’s what you’re asking,” Alec answered and Magnus’s heart dropped at that because he assumed Alec would have to leave searching for another target soon. But Alec kept speaking. “What are the odds? When my sister and I were presented the mission today, which was to talk to one High Warlock of Brooklyn,” and Magnus could hear some amusement in his voice at that. “She suggested she should go ahead and persuade him, as she’s been doing the whole interrogation thing for longer than I have. However, when I saw a picture of him…well, I dared to hope I would actually have good chances at this,” the Shadowhunter finished and though Magnus couldn’t see his face, he could feel the smirk in his words.

Magnus didn’t know how to feel about that at first. He had hoped that Alec came back to actually have a drink with him and to talk, but instead he was trying to get some information out of Magnus. While this situation wasn’t what he had hoped for, Magnus still decided to make the most of it. “Oh, well I have to tell you right now, the High Warlock’s information is way more classified than any you’ve gotten before, so I hope you are really good at your job, Alexander,” he teased, hands moving up and down Alec’s back.

Then, as if on cue, another song started playing and if this wasn’t the most suggestive song on the playlist then Magnus didn’t know which would be.

Alec seemed to agree because at that moment he moved his body slightly, placing a leg right in-between Magnus’s legs and full-on grinding on him at this point. “I have all night to persuade you, Magnus, I like my odds,” he said, taking Magnus’s hands and guiding them to his hips. The warlock was taken aback by a lot of things, one of which being the sultry voice in which Alec said his name. He liked that a lot. And before he could form another coherent thought, Alec turned his head and started kissing his neck and Magnus’s brain short-circuited.

Push the limit, are you with it?

Baby, don’t be afraid

I'ma hurt you real good baby

“Did you spend all night persuading those other Downworlders?” Magnus asked, congratulating himself for being able to form a coherent sentence with everything going on.

Alec pressed their foreheads together, looking at Magnus through hooded eyes. “Is someone jealous?” He asked teasingly. Magnus just shrugged. “If you really want to know… no. Dancing usually gets me all the information I need. I don’t even do this to others,” he muttered and then started placing more kisses on Magnus’s jaw.

The warlock groaned as he used his grip on Alec’s waist to pull him closer. “So why do it with me then?”

At that, Alec pulled back again and looked genuinely amused. “I can’t tell if you are too much of a gentleman or just daft,” he said, and Magnus felt mildly offended by that but he just looked at him with furrowed eyebrows. Alec took mercy on him and spoke bluntly. “You are just fucking hot. You’ve been undressing me with your eyes ever since that first night and I’ve been dreaming of you actually undressing me since then too.”

Oh, I bet you thought that I was soft and sweet

You thought an angel swept you off your feet

Well, I'm about to turn up the heat

I'm here for your entertainment

Magnus’s mouth formed a little o shape. Even though he knew he hadn’t imagined it, he still didn’t expect Alec to just tell him that so out of the blue and Magnus was never the type to take advantage of people, so he asked “Are you just saying this to get information out of me?”

Alec sighed at that and slowed his movements a bit, seeming a bit more serious and dropping some of his act. “No, I am not. You seem like a decent guy actually and I was sure that once I told you why we need the information you have for us, you would just help without wanting anything in return. But this mission just gave me an excuse to see you again and to actually get some time with you ‘persuading you’.” And Magnus probably still didn’t look 100% convinced because Alec added “You must know how ridiculously attractive you are, come on.”

Magnus looked thoughtful for a moment before a smug smile appeared on his lips again. “No one as hot as you has ever told me that, that’s for sure,” he replied and then he saw a blush appear on Alec’s cheeks again, which delighted him. The Shadowhunter tried to hide his face, but Magnus grabbed his jaw gently and turned his face back towards him. “I saw you flirt with people like it’s nothing and you walk around dressed like a wet dream. And yet a compliment makes you shy… You are very interesting, Alexander.”

The Shadowhunter looked back at him with wide eyes and with that rose color still on his face. “I don’t know…It’s not like the other guys don’t compliment me, but you are the only one who says it like you mean it and not like you just want to get into my pants… well, skirt.”

Normally, Magnus would have laughed at that last part but something else was bothering him. He was definitely in over his head in this one, because a moment ago all he felt was pure desire, but now that desire was mixed up with a need to always remind Alec just how pretty he was. But he did not want to say that out loud, because it would feel like too much too soon. And this was a Shadowhunter, he tried to remind himself. It was never wise to get too involved with a Shadowhunter.

“You are literally sin on legs, Alexander,” he settled on saying instead, trying to get the mood back to the way it was before. “Especially in those fishnets,” he added, his hands playing with the elastic on them again.

Alec seemed to accept the change in mood, because his shy look disappeared and was suddenly replaced by that hungry look Magnus had seen earlier. And then he did something that took Magnus by surprise. In one quick motions, he bent down and captured Magnus’s lips with his own. The warlock groaned into the kiss and opened his mouth and Alec gladly accepted the invitation to explore it with his tongue. It was a messy kiss, all teeth and tongue and pure lust. Alec’s hands had made their way to Magnus’s hair and were making a mess out of it. Magnus’s hands in turn moved from Alec’s waist to his back and under his skirt down to his ass, squeezing the flesh there.

They had been making out for a considerable amount of time before Alec pulled away. His pupils were dilated, and he was breathing heavily, catching his breath. “By the Angel…um, do you have a room we could like-”

“Yes,” Magnus said before Alec could even finish. He didn’t even care if he sounded a bit too eager, getting Alec alone seemed more important than his pride at that moment. So, without another word he took the Shadowhunter’s hand and led him away towards the backrooms.

Most of them were storage rooms, but Magnus did arrange to have one room with a bed, not necessarily for occasions like this, but rather for nights when he was too intoxicated to Portal back to his apartment. Right now, he thanked his past self for thinking of that because he thought he would explode if he didn’t get to have Alec right then.

When he finally got to the black door leading to the small room, he pushed it open, pulling Alec with him. He hadn’t even closed it all the way when Alec’s mouth was on his again and he found himself pinned against the wall. He was not complaining.

If Alec seemed needy before when they were on the dance floor, Magnus did not know what to call the state he was in now. His hands wandered all over Magnus’s body and then he let out a frustrated grunt. The next moment, his hands were on Magnus’s shirt, pulling the bottom that was tucked in out of his jeans and then making quick work of ridding him of the unnecessary barrier between them.

Somehow both Magnus’s shoes and Alec’s boots disappeared in that moment and Magnus was pretty sure he had been so eager that he accidentally used magic to take them off because he couldn’t be bothered to unlace any shoes right then and there.

Magnus put a hand on his shoulders to keep him from kissing him again, wanting to see Alec’s face. He huffed when he realized the room was still pitch black and flicked his hand, turning on a dim lamp, offering them just enough light to see each other. Alec looked absolutely wrecked and unhappy that Magnus had stopped their kissing session. But then Alec looked at Magnus’s eyes curiously and the warlock realized that the desire made his warlock mark show, his cat eyes the focus of Alec’s look.

He was going to say something but before he could, Alec put a hand on his cheek and growled. “Oh fuck, I thought you couldn’t get any fucking hotter.”

The last bit of sanity Magnus had left disappeared with those words and now he was the one desperately pulling Alec in for a kiss. Their mouths were on each other, biting and licking, as Magnus guided them towards the bed.

They made a quick job of discarding Alec’s crop top and now they were laying on the bed, Magnus on top of Alec and their bare chests pressed against each other. Magnus pulled away only to suck at a spot on Alec’s neck right where one of his runes was. The Shadowhunter was moving his hands aimlessly on Magnus’s body, as if he was trying to take every single part of him in, all at the same time. He let out a whimper when Magnus bit a bit harder on the spot on his neck and then the warlock pulled back, admiring his work which had left behind a purple mark.

“You’re wearing too many clothes,” Alec said, his voice raspy. His hands were already on the buckle of Magnus’s belt, fingers skillfully working to undo it.

“I could say the same about you,” Magnus said in response, hands moving down Alec’s body to his thighs and then up underneath his skirt. He let out a low groan when he felt Alec’s bulge covered by the fishnets and some lace and all the coherent thoughts left his body as he leaned down for another heated kiss.

Magnus almost whined in complaint when Alec tugged at his pants and he had to break the kiss and sit up in order to take them off. He started returning the favor, trying to find the zipper on Alec’s skirt when the other man put a hand over his and Magnus froze.

Alec looked up at him with uncertainty in his eyes and Magnus quickly removed his hands from his body, placing them on either side of Alec to hold himself up. “What is it?” he asked carefully, despite how worked up he was already.

But the Shadowhunter just looked down shyly as if he did not know what to say. Or rather as if he didn’t know how to say whatever was on his mind. Some of the urgency in Magnus was starting to dissipate and he looked down at Alec with a kind smile. “Hey, talk to me, Alexander. We can stop this whenever you want.”

At that, Alec shook his head vigorously, as if that was the most ridiculous idea he had heard and Magnus let out a sigh of relief. “No, I really, really want this. It’s just…Is it okay if you leave the skirt on? Like, take everything off but the skirt,” he muttered and Magnus had to really focus to hear him because he was so quiet.

Oh. Oh, the things that that request did to Magnus. Alec Lightwood was making him discover things about himself he did not even know. Like the fact that he really needed to see Alec with only that black skirt on.

“Yeah,” Magnus said breathlessly, hands wandering down Alec’s body again. “Yeah, that is more than okay, Alexander. I would be a fool to complain about fucking you in a skirt.” His hands sneaked under Alec’s skirt again and this time, Magnus grabbed the fishnets he was wearing and pulled them down in one swift motion. The little gasp that Alec let out was cute and hot at the same time and Magnus did not think that was fair.

The only thing Magnus was wearing right now were his boxers and Alec seemed very adamant about taking those off him as quickly as possible. Once Magnus confirmed that Alec wearing a skirt was more than okay, Alec went right back to acting needy, hands all over Magnus’s bare body until they reached the waistband of his boxers. He looked up at Magnus questioningly again with those big doe eyes and Magnus felt himself twitch at the sight.

So he sat back again and let Alec rid him of his boxers. And he did not miss the hungry look on Alec’s face when he first saw Magnus’s body in all its glory. The Shadowhunter licked his lips as he looked down at Magnus’s hard cock that was leaking precum.

“Fuck,” was all Alec managed to say before Magnus pressed him against the mattress again and started kissing him ungracefully, a clash of tongue and teeth. Alec sure knew how to kiss like he meant it and Magnus couldn’t get enough of it.

He was grinding on Alec’s thigh and the man underneath him was letting out the cutest whimpers whenever their lips parted. So Magnus decided to take mercy on him.

He broke the kiss and started leaving a trail of kisses down Alec’s body, from his neck to his abdomen and then lifting his skirt, which was now bunched up around his stomach, revealing everything from the waist down. He sucked particularly hard on a spot on Alec’s thigh, making sure to leave another little reminder of what they were doing.

Then, his attention went to Alec’s crotch and Magnus’s breath caught in his throat. The man was wearing a pair of pink lace underwear and his cock was clearly visible through the material, begging to be released of that constraint. So, Magnus wasted no time before removing the Shadowhunter’s lingerie.

“You’re so pretty,” he muttered, admiring Alec’s body. Alec took in a sharp breath at that and it made Magnus smirk. Oh, there were so many things he wanted to do this man. He wondered how Alec would react if Magnus sucked him off, wondered about the pretty sounds that would leave his mouth. “What do you want, doll?” he asked instead, and was pleased when Alec’s cock twitched at the pet name. Magnus couldn’t help himself and gave it an experimental tug, pleased when Alec arched his back and his hips jerked up.

It seemed like the Shadowhunter was having a hard time remembering how to speak. “Ah-Fuck me, Magnus, ” Alec pleaded, voice cracking.

If Magnus was feeling like a tease tonight, he would ask him to elaborate. But the truth was that he was just as worked up as Alec and that he needed to fuck him as soon as possible or he might positively explode. So he hummed in agreement and a bottle of lube appeared next to him with just a flick of his wrist. “Tell me if this hurts at all, okay, doll?” he said and then waited for Alec’s nod before he spread the lube on his fingers and pressed one finger against Alec’s hole.

“Oh my fucking God,” Alec cried out when Magnus pushed the first finger in. The Shadowhunter was desperately gripping the sheets and moving his hips, trying to get Magnus’s finger deeper inside him.

The sounds that Alec made were music to his ears. It was a mix of Magnus’s name, swearing and a plea for more and Magnus was getting harder by the minute just because of that. He took his time prepping Alec though, making sure that he would be properly ready to take him. He started kissing Alec’s thighs again as he pressed a second finger inside Alec and fucked them in and out of him slowly, making sure he wasn’t hurting the other man.

Once he was able to slide three fingers in and out of Alec without much resistance, he decided that they have both waited enough. He took his fingers out completely and Alec cried out because of the emptiness. But Magnus quickly repositioned himself, the head of his cock pressed against Alec’s entrance and his face hovering over Alec’s face again. “What do you want, Alexander?” he asked, because he still felt like a bit of a tease.

The Shadowhunter did not hesitate before speaking this time. “Your cock. You better put that inside me right now or I am going to-” Alec did not get the chance to say what he was going to do because Magnus started pushing into him at that very moment and his words turned into a loud moan.

And fuck, Magnus had spent the whole time prepping him thinking about how good it would feel to be inside Alec, but this is even better than he had imagined. He slowly bottomed out before he started thrusting in and out at a steady pace and Alec was so hot and tight around him that now the warlock was the one finding it hard to form coherent words. “You’re doing so well, doll. You’re taking my cock so well,” he whispered as he nibbled at Alec’s earlobe. The Nephilim shuddered at the touch.

He looked down at Alec and noticed the Shadowhunter had closed his eyes. Magnus did not like that because he wanted to see him fall apart underneath him while Magnus was wrecking him, so he put one hand in Alec’s hair, pulling gently. “Look at me,” he said, and Alec immediately obliged, opening his eyes and looking up. His pupils were dilated so much that his blue eyes almost seemed black now. That made Magnus go faster and Alec seemed to be more than okay with that because his arms wrapped around Magnus, his nails scratching at the warlock’s back.

“Fuck. Right t-there,” Alec muttered, biting at Magnus’s neck so hard Magnus thought he might draw blood.

Magnus placed both his hands on Alec’s hips, getting a good grip as he let go of all the self-control he had left and thrusted in and out relentlessly, getting the sweetest sounds out of Alec as he hit his prostate spot-on every single time.

The warlock felt a familiar heat building up inside his stomach and knew he was getting close. “I’m going to come, doll, where do you want it?” he asked, slowing down just a little bit.

Alec did not seem happy at the change in pace because his grip on Magnus’s body tightened and pulled him closer. “Just like that. Don’t stop,” Alec muttered, holding on for dear life.

Magnus did not expect that reaction, but he did not complain. “How are you so fucking perfect? Want me to come inside you, pretty boy?” Alec let out a desperate cry at that. Magnus quickened his pace again, fucking Alec until they were both sweating and out of breath and then, with one final thrust, he finished inside Alec with a low moan.

He felt Alec’s hole tighten around his cock just a few seconds after and then he felt something wet on his abdomen. When he looked down, he noticed Alec had come untouched right after Magnus came inside him and there was cum all over their abdomens and all over Alec’s skirt now.’

“Fuck,” Magnus muttered as he slowly pulled out his now softening cock. When he looked down, he saw his own cum start to leak out of Alec’s hole and that sight alone almost made him hard again.

He laid on his side, looking over at Alec, who looked like he was in a daze and who had yet to move. Magnus would be lying if he said he wasn’t at least a little bit proud of the fact that he rendered the Shadowhunter speechless like that.

“I hope you don’t mind if…I lay here for a couple more minutes,” Alec said, turning his head to face Magnus.

The warlock chucked and shook his head. “Not at all, I have quite the view here,” he said, looking pointedly at Alec’s body. His eyes landed on the skirt that was drenched in cum and he made a face, snapping his fingers. Within just moments they were both clean as if they had just had showers and Alec’s skirt was spotless again. “There, I suppose that’s more comfortable,”

“Thank you,” Alec muttered and then his eyelids fluttered closed.

Magnus knew that he should probably wake the Shadowhunter up and ask him to leave. He never let one night stands sleep over, especially not Shadowhunters. But this one… this one made Magnus do the one thing he never thought he would be doing. He laid down next to Alec, pulling the duvet over them and placing an arm on his chest as he, too, drifted to sleep.

Magnus woke up a few hours later with someone next to him. Which wasn’t a surprise at first, but then he opened his eyes and saw the runes on the person in his bed and all the memories of the previous night came back.

It was still dark outside, so it was early, but Alec was awake as well and he was just staring at the ceiling.

“Good morning,” Magnus muttered, stretching his arms.

Alec looked surprised to see he was awake. “Good morning,” he said carefully. “I am sorry, I don’t usually spend the night. I don’t know what the protocol is... Is it weird that I didn’t leave in the middle of the night?”

The warlock looked over at him and chuckled. Was this guy even real? “There is no protocol, you know? This is not one of your missions,” he muttered, but then he remembered that Alec was technically on a mission, and he smirked as he traced a shape on Alec’s chest with his finger. “Actually, I think you must be the worst Shadowhunter I’ve ever met.”

Alec looked genuinely offended at that and his eyes narrowed. “Why are you saying that?”

“Well, you did all this to persuade me to give you some information, but you still haven’t asked me any questions,” Magnus said, amused.

It seemed as if that was the exact moment Alec remembered he was there on a mission. “Oh shit,” he said, looking for his boots that were discarded on the floor and taking out a phone. He quickly started typing something, probably to let his team know he was not dead.

“You keep a phone in your boots?” Magnus asked, raising an eyebrow.

“Have you ever seen fishnets with pockets?”

“Fair enough.”

After he finished typing out his text, Alec turned to Magnus, his expression hard to read. “First of all, the events of last night were way more than just me persuading you. I don’t just have sex with people for information. I have sex with people I find incredibly hot and who can fuck me into next week,” Alec said and the fact that he said that with a totally straight face made Magnus smile. “Second of all…yeah, the mission…”

Magnus sighed, starting to put his clothes back on because it seemed like they were going back to all business. “What would you like to know, Shadowhunter?”

Alec seemed taken aback by the fact that Magnus was calling him a Shadowhunter, he even looked a bit… hurt? But he cleared his throat and said “Did you happen to steal the memories of a Shadowhunter called Clary Fairchild at the request of her mom? She kind of needs them back.”

To say the name was familiar to Magnus would be an understatement. He knew exactly what Alec was talking about and he was well aware that there was only one reason the Nephilim would be interested in finding Clary’s memories. “Because of Valentine,” he said, and Alec nodded. “I am sorry to have to tell you this, but I don’t have Clary’s memories anymore. I can help her get them back though. It is a bit of a complicated ordeal, but I can explain it all to her myself.”

The Shadowhunter’s eyes widened. “Are you suggesting I take you to the Institute with me?”

Magnus understood the implication of that and smiled smugly. “Oh, well, I let you stay the night, Alexander. You might as well invite me to your home and introduce me to your family while we are at it,” he joked, but the scary thing was that it did not feel like a joke in his heart.
