Magnus was very confident when it came to his sex life. Likes, dislikes, kinks, he wasn’t afraid to lay it all out on the table without remorse.
However,
Magnus has a thing for cars.
Specifically hot guys in hot cars.
He would never admit out loud it was anything beyond a thing, even though it is most certainly a kink. Alec teases him about it relentlessly, though he happily obliges Magnus whenever the warlock wants to go out for a drive. They both return home thoroughly satisfied and maybe, just maybe, it’s a thing for Alec too.
Magnus had started it. It had escalated from dirty words to wandering hands to eventually a very confident mouth. It had taken Alec some time, but soon he too was leaning over the center console to suck his boyfriend off as he drove.
Boyfriends turned to fiances turned to husbands turned to fathers turned to immortal husbands and yet they still gave each other blowjobs while they were driving like they were horny teenagers with no other outlet for their sex drives.
So yeah. Maybe they both had a thing for hot guys in hot cars.
Wednesday nights were date nights. Days where Magnus would ensure he didn’t have any clients after six and Alec would make sure his patrols, meetings, and paperwork were done by the same time. Their family took turns watching the boys, though they were getting to a point where they didn’t need watching anymore. Rafe was fourteen and Max was twelve, both very capable of keeping themselves safe. Having an adult watch them was less about keeping them safe from demons and other enemies and more about keeping themselves and their loft safe from each other.
When Alec came home Wednesday night to see his mother on the couch with Max talking to Magnus who was twirling the keys to the mustang around his finger he stopped cold, hand on the doorknob, eyes fixed on the keys.
“Good evening, darling,” Magnus smiled, fully aware of the implications of the keys in his hand and what was going through Alec’s head, “I was starting to worry you forgot about me,”
“I could never,” Alec said sincerely, shutting the door before taking off his weapons, “we had a large nest to take care of today. Some of the younger kids got hurt, so I stopped by the infirmary on my way out,”
“Are they okay?” Max asked quickly, looking at Alec with wide, worried eyes.
“They’re just fine, Blue,” Alec told him, “just some scratches,”
“You should call me next time,” Max said, “I can heal them,”
“I know you can,” Alec smiled at his son, always the first to want to jump up and help, “the next time we need a warlock healer, I’ll make sure I call you and bapak,”
Max nodded, satisfied with Alec’s answer before turning to Maryse and beginning to talk to her.
“Where’s Rafe?” Alec asked, glancing around and seeing no sign of their twelve-year-old son.
“In his room, where else?” Magnus joked, “was he on that hunt earlier? Was he hurt?”
“He was on the hunt but he wasn’t hurt. Jinora was though,” Alec said, “it’s the first time she’s been hurt since they bonded,”
“That would explain why he only grunted at me when he came in,” Magnus thought aloud.
“Yeah, I remember the first time Jace was injured after we bonded. It was a strange sensation,” Alec explained before turning to his mother, “mom, could you make sure he eats? And if he feels he needs to go back to the Institute, let him,”
“Of course, sweetheart,” she smiled, “now you two go have fun,”
“Oh, we most certainly will,” Magnus smiled, looping his arm through Alec’s.
“Wait, I wanted to change,” Alec began to protest, but Magnus only snapped his fingers. He now wore aviators, a thin white t-shirt that barely counted as a t-shirt because you could see his chest hair through it, a pair of jeans, and a bright green jacket.
“Green? Really?” Alec asked, looking down at the jacket.
“Come on, Alexander, a little color won’t kill you,” Magnus said, dragging him out the door.
“Have a good night, boys!” Maryse called.
“We will!” Alec yelled back, shutting the door behind them, “did you really need to swing the keys around in front of my mother?”
“What? It’s not like she knows,” Magnus wrapped both his arms around one of Alec’s, “I’m pretty sure Jace is the only one who knows,”
“What? Jace knows?!” Alec stared at his husband incredulously.
“Unless he’s the most oblivious shadowhunter to walk the earth, then yes, he knows,” Magnus conceded as they made their way down the stairs.
“How?!” Alec continued gawking at him.
“Remember when he asked if I would teach him how to drive a stick?” Magnus asked, to which Alec nodded, “well, when we went to get in the car, there was still some...evidence, on the seat,”
Alec only groaned and buried his head in Magnus’ shoulder. He stayed hidden there until the elevator doors opened and they stepped into the parking garage.
“Where shall we go tonight, darling?” Magnus led them to where the car was parked, “Malibu, the autobahn, mountains upstate,”
“The autobahn seems dangerous,” Alec remarked as he pulled away from Magnus and stepped around to the driver's side of the car.
Magnus tossed him the keys which he caught easily before they both climbed in, “Malibu? We haven’t been there in a while,”
“Works for me,” Alec started the car as Magnus opened a portal against the wall in front of them. Neither bothered to put on their seatbelts as Alec put the car in drive and drove through the portal, depositing their car on a road on the side of a mountain that overlooked the beach. Alec took off down the road, letting the car rev beneath them as they sped off.
It didn’t take Magnus’ hands long to start wandering.
“Someone’s impatient,” Alec smirked as he felt Magnus’ hand rubbing up and down his thigh.
“I don’t know what you mean, darling,” Magnus smiled with faux innocence.
“I bet you’ve been thinking about this all day,” Alec took a sharp turn which forced Magnus’ hand right against his dick.
“And would you punish me if I had?” Magnus’ voice was low and seductive.
“Maybe,” Alec shrugged, “I might tell you, for instance, to get your mouth over here and make good on what you’re promising me right now,”
“You don’t have to tell me to do that,” Magnus began moving his fingers to undo the button of Alec’s jeans, “I was already planning to,”
Magnus shifted so it was easier for him to lean over the center console. His knees came up on the seat and rested his body between the center console and the gear shift, his ass in the air, allowing Alec to bring his arm to rest Magnus’ back in a practiced motion. With one hand, Magnus unzipped Alec’s jeans and used his other to pull his half-hard dick from his pants.
Magnus' mouth watered at the sight of it. He pulled Alec’s balls out as well, pushing the waistband of his underwear down a little so it could rest easily before he began to stroke him. Alec moaned lightly as Magnus coaxed him to full hardness, pressing little kisses to the tip and teasing his tongue against the slit.
“You gonna keep teasing me like that?” Alec asked, rubbing his hand up and down Magnus’ back before slapping his ass.
“Good things come to those who wait, darling,” Alec could practically hear Magnus’ smirk as he continued at his current pace. Alec let his hand go under Magnus’ waistband and grab at his bare ass. Alec squeezed harder as Magnus scraped a nail up the underside of his dick.
“Magnus,” Alec growled, kneading his ass. Magnus pressed another kiss to the head of his dick before slowly sucking it into his mouth. Alec sighed happily as part of him was finally engulfed in the warm, wet heat of Magnus’ mouth. He suckled on just the head, letting his tongue swirl around it and continue teasing at the slit.
With both their busy lives, it was rare that Magnus took this long on a blowjob, but clearly he had plans to draw this one out. He pulled off his dick with a small pop before moving down his shaft, leaving little kitten licks behind him as he went. Alec, on a relatively straight patch of road, chanced a glance into his lap to see Magnus taking his balls into his mouth, cat eyes fully on display as he made eye contact with his husband.
“God, Magnus,” Alec moaned as Magnus brought both his balls into his mouth. He focused back on the road, knowing this would be over far too soon if he continued to look. As Magnus sucked his balls, rolling over them with his tongue, Alec continued to play with Magnus’ ass, occasionally slipping a finger between his cheeks and teasing his hole. Magnus would moan and Alec would feel the vibrations through his whole being.
Alec was having a more difficult time focusing on the road as Magnus continued. He eventually let Alec’s balls fall from his mouth, a line of spit still connecting them until Magnus licked up his shaft and finally took Alec fully into his mouth. Alec nearly howled in pleasure as Magnus finally gave him what he wanted.
Magnus pressed down, breathing through his nose as he felt the tip of Alec’s cock hit the back of his throat. The short hairs at the base of his cock tickled his nose before he pulled off, took a deep breath, and dove right back in. He took Alec into the back of his throat, held him there for as long as he could, pulled off, and then repeated the process. Alec felt rather than saw the amount of saliva that was building up and couldn’t help but be turned on even more by how sloppy the whole thing was.
When Magnus was satisfied with the amount of deepthroating he’d done, he only pulled off Alec’s dick halfway before beginning to bob his head up and down, making loud slurping sounds as he sucked him off. Alec moaned loudly as it seemed that Magnus had finally decided to get him off. The white-hot heat began to curl in his gut as Magnus continued without stopping.
“Magnus, I’m gonna come,” Alec warned him, and, to his credit, his husband only redoubled his efforts.
Alec couldn’t help but close his eyes as he finally came down Magnus’ throat, letting his hand move from Magnus’ ass to tangle in his hair. He was so completely lost in the moment, his foot pressing down more on the pedal, as Magnus continued to suck him. Which is why he didn’t see the upcoming turn in the road and why he didn’t take it.
Going at such speeds, the car broke through the guardrail easily and they were flying over the side of the cliff. Magnus acted quickly and threw out his hands, casting a spell that would encase them in their own protective bubble as they fell. The car bounced down the rocks, creaking and crunching as it went, but they stayed safely contained in their bubble, the metal of the car contorting in a circle around them.
Slowly, their momentum came to an end and the car was deposited upside down on the beach that had, until a moment ago, been below them. Magnus cast another spell on the car, shifting it so it was upright before letting the bubble disappear and drop them into their seats.
They both sat there in shock for a moment, neither saying anything, only catching their breath as they realized exactly what happened. When Magnus began coming to his senses, he snapped his fingers, fixing the guardrail and casting a glamour over them to deflect mundane suspicion. They were both fine, they didn’t need mundane doctors poking and prodding at them.
“Are you okay?” Alec asked, still breathing heavily as he took in their surroundings.
“Yeah, you?” Magnus nodded, his voice still hoarse from the blowjob.
“Yeah,”
“Well then,” Magnus exhaled, slapping his hands against his thigh as he looked between Alec and the destroyed car, “you’re not allowed to drive anymore,”
“I’m not allowed to drive anymore?” Alec raised an eyebrow as he tucked himself back into his pants and zipped them, “as if this was my fault!”
“It is your fault!” Magnus laughed, “you were the one driving the car!”
“But you were the one who was distracting me from driving the car,” Alec reminded him as he forced open the door of the destroyed car and climbed out, “and I just fell off a fucking cliff with my dick hanging out, so maybe cut me some slack there too,”
Magnus followed suit, resorting to blowing his door off with magic before stepping out, “yes, but you were the one who lost control and wasn’t paying any attention to the road!”
“Stop pinning this on me! You started it!” Alec pointed an accusatory finger at him as he came around the car to be next to him.
“I started it?!” Magnus stared at him wide-eyed, “you were the one who told me to suck your dick!”
“But you were the one who said we should go driving tonight! I wouldn’t even know how to drive if it weren’t for you, and I certainly would not be remotely interested in giving blowjobs while driving if you hadn’t introduced me to it!”
“Oh, yeah, that’s true,” Magnus conceded, “but you enjoy it and you can’t deny it,”
“I do,” Alec nodded, wrapping his arms around his husband and pulling him against his chest, “but not when you make me come so hard I drive off a cliff,”
“Maybe Malibu wasn’t the best place for this,” Magnus offers, staring back up at the roadway.
“Maybe not,” Alec laughs before taking a deep breath in, “but seriously, you’re okay, love?”
“I am,” Magnus nods in affirmation, “a little shaken, but physically, I’m okay. Are you?”
“Yeah, thanks to you,” Alec presses a kiss to his temple, “I’m not sure how interested I’m going to be in giving or receiving blowjobs while we’re driving in the future though,”
“For starters, it’s called road head,” Magnus replied and Alec only laughed, “and secondly, we can still give blowjobs in the car while it isn’t moving. Go park in some secluded area where all the mundanes go to have car sex,”
“That could potentially be arranged,” Alec smirked, pressing a few sloppy kisses against Magnus’ neck before turning back towards the car, “but I think we’d actually need a car to do that,”
“Hmm, we would, wouldn’t we?” Magnus glanced at the totaled car, which was really just a hunk of metal with a front cab he’d protected enough to keep from crushing them, “I don’t even think I could salvage that with magic,”
“Probably not,” Alec remarked, looking at it again, “but this means that we can go pick out our own car, together,”
“Oh yes it does,” Magnus chuckled, “and we have to make sure we take each one on a very thorough test drive,”
“Magnus!” Alec scolded him which only made Magnus laugh more before he pressed a kiss to his husband’s lips.
“How about I banish this car, we go get a nice seafood dinner, then get a hotel room and finish what we started?” Magnus suggested, resting his chin on Alec’s chest and looking up at him.
“I think that sounds like a great idea,” Alec pressed a quick peck to his lips before shifting Magnus in his grasp and letting his hand come around his waist. Magnus snapped his fingers and the steaming hunk of metal that was his car disappeared, reappearing in a local junkyard. He leaned back into his husband’s side and mirrored his motion as the two made their way down the beach in search of a meal.
