A/N: Right! Umm I don't even know okay? I was listening to Fever and reading City of Glass and this happened. Also, if you haven't listened to the song…wtf DO IT, it's awesome, as is Adam Lambert…and Magnus Bane…and Alexander Lightwood…aaaand I don't own any of them, to my chagrin.

When Magnus opened the door to their apartment, the music was loud enough to cover the noise of his footsteps. It was that stupid song again. Damn it.

He never really understood the fascination Alec had with that Adam Lambert mundane. He was far more fabulous and gorgeous…right? Sure, he was as sparkly as him, and the fair skin and jet-black hair had a slight resemblance to his own and maybe he was a little bit flamboyant…and OK his voice was actually pretty damn awesome but he didn't particularly care for anyone who captured his shadowhunter's attention like that.

That was of course, until he stepped into the kitchen and saw Alec gyrating his hips sensuously along to the beat of Fever.

Holy shit he's hot, was Magnus' last coherent thought.

Unlike the shy little Alec that had come to his party and blushed when Magnus slipped his number into his pocket, he had become far more confident and comfortable enough to walk around the house in only his boyfriend's black silk boxers. However, nothing could prepare Magnus for this.

Alec was not only moving his hips but also throwing his head back and snapping his damp hair from side to side with his eyes closed blissfully. He was mouthing the lyrics as well, with a hairbrush that posed as a microphone.

Oh baby lights on but your mom's not home

I'm sick of lying down alone, with this fever, fever.

His boyfriend's muscled torso was shining with a thin layer of sweat and his nipples had peaked at some point during the song. His free hand, the one not holding onto the hairbrush slipped slowly down his body until it reached the waistband of his boxers, and with a mesmerizing undulation of his hips, he took them off entirely.

Magnus just stood there. He couldn't move his feet or pick his jaw off the floor.

My one and own, I wanna get you alone

Give you a fever, fever, yeah…

At that moment, Alec's eyes snapped open and Magnus swallowed at the predatory look in them. Before he even knew what happened, he was pressed against the wall, with a very naked, very horny and very fucking sexy shadowhunter.

"Happy to see me?" asked Alec, brushing his hand over the bulge in his rainbow-colored pants.

"I fucking love that song." Was Magnus response, the best he could do with a sweaty Alec in such close proximity.

"Oh?" Alec said between tiny bites and swift licks at his neck "I thought you didn't like him."

If he hadn't known better, Magnus would say his boyfriend looked innocent, but he was positive Alexander, devious little shit, knew exactly what he was doing to him, and he was sure they had a fun night ahead of them.

His thoughts were confirmed when Alec came even closer and whispered in his ear with a low, filthy voice "Give you my f-f-fever, my f-fever."

He pulled his boyfriend close to him in a searing kiss and half-danced him towards their bedroom, the music still playing in the background.

Why did he ever dislike that mundane singer again? Favorite. Song. Ever.

-.-.-.-.-.-.-

Erm…the end. Review please? :D
