A/N: This chapter and the next one are for cheesekun and RedCoral with Alec trying to get some jealousy out of Magnus intentionally. I made two versions out of this idea because my first one didn´t get so well (in my opinion at least). This chapter is the not-so-good-one, but the next will follow soon after ;). (Sorry if Alec is a bit OOC here...) Hope you enjoy though :)

Alec POV

Magnus eyed Alec with a judging expression. „Couldn´t you have dressed better for one night? Is that too much to ask for?"

Alec took a deep breath. „What do you mean? It´s the best sweater I have." he tried to lift the mood with an ironic comment, but Magnus just snorted.

Of course he understood that Magnus was stressed today and the clients had left him pissed off and everything, but did really have to be that cranky? The way Magnus treated him right now was unnerving and his bad mood started to rub off on him more and more.

„Alec, hurry, the others are waiting for us. For a shadowhunter you´re freaking slow!"

Alec would have laughed if not for the harsh tone with that Magnus had spoken to him. „The others can wait a bit longer, it doesn´t kill them." he retorted. He didn´t want to go to Pandemonium in the first place, so he could as well delay their arrival a little bit. At the beginning of the day he had hoped for a nice, cozy evening on the couch, snuggling up to his boyfriend under blankets watching a random mundane movie.
But then Izzy had called, having this brilliant idea to go out partying with the gang... again! And then one rude client after the other had visited Magnus, who got more annoyed by the minute.
The evening Alec had planned was ruined.

The shadowhunter put his hands in his pants pocket and followed his boyfriend reluctantly. When they arrived at Pandemonium Magnus immediately left Alec to talk to Clary and Simon who were the only ones of their friends that were findable.
Alec sighed and made a move towards the bar to allow himself a drink. Or two.
Meanwhile he pondered about a way he could somehow make the night turn to good account.

„Hey, Alec!" It was Izzy who had been sneaking up on him out of nowhere. Alec cursed under his breath.
„Oh my, why so fretted? Is something up?" she asked. Alec sighed. „No, nothing. That´s kind of the problem." he muttered.
„Ah, I see." Izzy nodded understandingly which caused Alec to straighten himself. „No! That´s not what I meant." he said, maybe too quickly, because Izzy´s brows shot up. Alec glowered at her. „I mean that Magnus and I have a little fight. Nothing serious, but I had hoped –"
„That you´d get laid tonight." His sister cut in and nodded knowingly.

Alec´s eyes widened. „ISABELLE!"

She laughed. „Come on, we both know it´s true. Now with Magnus being mad at you your chances are a little off. I see why you´re so upset."

Alec looked more horrified by the minute. „Iz, I really don´t want to talk with you about my sex life. That´s just... not good."

Isabelle laughed. „I get it. Just let me tell you one more thing: if you make Magnus jealous, he´ll forget about whatever you´ve been quarreling about and your day is saved, if you know what I mean." she winked at him.

Alec gulped. „That´s nonsense. That will rile him up even more."

Izzy grinned. „Exactly." she said. „You can give it a try."

Alec showed her his best scowl but stayed silent, too shocked for a smart comeback. Instead he decided to ignore her and took another gulp of his drink.

„Oh damnit! Sorry!" he heard a voice from beside him. He looked up to see that someone had appeared at the place next to him and had spilled some of his beer on the bar. A part of his sleeve was wet now.

„It´s not a big deal." Alec said. He wanted to turn away again.
But then he took a closer look at that guy and realized he was really good looking. Like smokin´.

Izzy smirked at him suggestively, before she left them alone.
Alec hesitated. Should he really do that?

He glanced over his shoulder and spotted Magnus standing at some distance still talking to Clary. Isabelle had grabbed Simon and dragged him to the dancefloor where he was bobbing to the music rather awkwardly.

Alec bit his lip. He was somewhat mad that his boyfriend ignored him so resolutely and he had counted on getting some time alone with Magnus in the night. It had been a stressful day for him as well. But did he complain? (Well, maybe a bit.)

You can give it a try.

Izzy´s voice echoed in his head. He couldn´t get the thought out of his mind. Alec looked over to the sandy blond boy next to him. The guy caught his glance and shot him a polite smile which Alec returned.
„Now that you spilled your drink, I could buy you a new one." he suggested bluntly.
The guy smiled weakly. „Not necessary." he said. Alec peeked at his boyfriend who was in just the right position to oversee the bar where Alec was sitting and chatting with the fair-haired beauty. „I insist.", he said, not willing to give up his plan just yet.

For the first time, the other guy looked Alec directly into the eyes. He seemed confused.
„I... I´m not sure, are you trying to hit on me? Because I´m not... I´m straight. Sorry." the blonde said.

Alec´s grin just turned wider. „That´s perfect."

The guy next to him looked even more puzzled. „You do know what being straight means, right? It says that I am not attracted to guys. I only fancy girls." He shrugged apologetically.
Alec blinked. „Right." he said. „I-I know that. It´s just..." he sighed. „Can I ask you a favour?"

The blond eyed him warily, clearly uneasy about what was coming next.
Alec laughed nervously. „It´s nothing too awkward, I swear! I´d need you to kind of act as if flirting with me so that my boyfriend gets jealous... Does that sound crazy? I bet it does. Okay, forget about it –"

„I´m in!" the blond boy interrupted him suddenly.

Alec was dumbfounded. „Really?"

The guy grinned. „Yeah. I like drama. Sounds like fun." he said. „I´m Ryan, by the way." he offered Alec a hand which he took after a startled moment. „I´m Alec."

Ryan looked around the room. „So who´s the lucky guy? I´d like to know who I´m competing with." Alec laughed. He gave the bartender a sign to get a new beer for Ryan as a thank-offering for his favor, before opening his mouth to answer.

„Alexander!" A familiar voice came from the other side of him. „Who´s that guy?" Magnus leaned over the bar so that he was able to scrutinize Ryan completely and was still in close body contact with Alec to mark his territory.
But Alec was determined to cold-shoulder him, if only temporarily. So he just gave Magnus a short glance over his shoulder before turning his attention back to Ryan. „That´s Ryan. Ryan, this is Magnus, my... friend."

Ryan did his best to not laugh out loud. Alec shared a look with him and he understood. Both of them ignored Magnus´ gasp at how Alec called him a friend.

„Sorry for the interruption. What were you saying?"

Ryan cleared his throat. „Uhm... I said you are really good looking."

Alec raised an eyebrow at him. A little bit more subtle, he mouthed. Ryan bit his lip.

„Thanks. Well, you´re too." Alec said. What was that about nothing awkward? he thought.

„Sorry, that was the worst pick-up line in the history of bad pick-up lines." Ryan chuckled. „Forget about that. I wanted to ask you if you do sports, because you seem to be fit."

Alec nodded. He assumed the guy to be a mundane, so he couldn´t tell him he was training daily to fight demons. „I do all sorts of things. From sparring to just jogging, simply to stay in form."

„Ah, that´s cool." said Ryan. „I play football. I´m the quarterback, they say it´s a real chick magnet to be in this position... uh, dude magnet in my case..." he added when Alec shot him a warning look.

Alec did everything to hold back a laugh. „I can see how that works."

„There is a party my football team is throwing next Friday. It´s an outdoor event and I´d like you to come if you have time."

„Sounds good. I think my sister would love –" Ryan put a hand on Alec´s knee and looked him right in the eyes, making him shut up. „Actually I hoped you would come alone." he whispered. His voice was just loud enough for Magnus to hear it too.

„Sure." he answered. „I´m glad you invited me"

Behind him Alec could felt how Magnus retreated from his place at the bar.
Suddenly he feared that he´d gone too far. Maybe this was a mistake. Of course it was, stupid Lightwood! It was a stupid idea from his stupid sister and he should´ve never –

Alec breathed out as he saw Magnus reappearing on the other side of Ryan. He was staring icily at Ryan´s back and if looks could kill, then Ryan would have a big problem right now.

Alec grinned. Maybe the plan wasn´t that bad after all.

„You know," Alec started. He was looking directly at Magnus while speaking, his blue eyes sparkling. „I always had a thing for blonds. It´s my – how do they say? Kryptonite?!" He had overheard the word from Simon, when he said that Izzy in gear was his kryptonite.

At that Magnus looked up and met his gaze. And it seemed as if he was slowly understanding what was going on. His cat-like eyes shone darkly when his lip twitched up in a dark smirk.

„It wakes the desire in me to run my finger through your hair." he went on, not averting his eyes from Magnus for a second. Ryan snickered silently. „Go ahead." he said.

Magnus inhaled sharply as Alec reached out to touch Ryan´s hair. Alec had a hard job stopping himself from laughing which was only more difficult since Ryan´s face reddened from laughing all the time.
„If you ever want to continue this in a more private area," Ryan said as soon as he was sure his voice wouldn´t drip with amusement. He took a napkin and scribbled something on it before handing it over to Alec.

„Here´s my number. Feel free to call me whenever you are in desperate need for a fair head." With that he stood up, and ran a hand over Alec´s shoulder as he left. But there wasn´t a number on the napkin, Alec realized when he looked at it. It was a short text.

I hope I was a help tonight ;)
Tell your boyfriend I´m sorry.
Ryan

He smiled softly as he read, though for another reason Magnus might be thinking.

Alec locked eyes with Magnus while he pouched the napkin into his pants pocket. Magnus grabbed Alec´s hand hard before he could reach for his glass.
„Don´t think you can get away with this so easily.", he growled. „I can see through you, Shadowhunter. Flirting with someone else in front of my eyes. Nasty!" Alec gulped. Magnus was standing too close to resist. Alec was about to give in to his touch as the warlock stepped away. He hadn´t loosen his grip so that he was dragging Alec directly out of the club and into a deserted alleyway.
There he pushed Alec up against the wall, cold stone pressed against his back but he couldn´t care less because Magnus was kissing him fiercely and every anger or disappointment or stress he had felt this day drained out of him.
„Magnus," he said a little breathlessly in between two kisses. „Portal." It were only two words he could voice, but it was enough. He didn´t see what Magnus was doing with his hands through the haze of lust that was occupying him, he only recognized they weren´t on him anymore.
Just before the lack of contact became unbearable, Magnus´ hands were at his shoulders again and he pushed him against the wall again, only this time there was no stone at his back, and he felt like falling through air. A second later he landed on the hardwood floor of Magnus´ loft and his boyfriend fell on top of him. „Bedroom?" he asked, but Magnus shook his head. „Too far away."

Alec´s chuckle was cut off by Magnus´ lips on his.
„Now what was that about blonds?" Magnus asked in a low voice.
„So... unattractive!" Alec said and he saw Magnus nodding approvingly.
„And?"
Alec´s head was so light and it was hard to think a coherent thought. „And..." he started. „You´re the best boyfriend in the world and I can be grateful to have you?"
„That´s right, darling. That´s all I wanted to hear." the warlock murmured before leaning down again and pressing his body against his boyfriend.

Izzy´s a genius. Alec thought. But I sure as hell won´t ever tell her.

He would tell Magnus later that Ryan didn´t actually give him his number. He´dalso tell him that Ryan was straight.

But before that he would enjoy the rest of the night whole-heartedly and learn once more how intense Magnus got when he was jealous.
