It's a perfect afternoon at the Institute. Everyone is out running errands and the only person left inside is Jace. Clary is out buying new paint brushes for a new project. Alec stayed over at Mangus's apartment last night so there is no telling when he would be back. And Isabella was out shopping for the perfect black boots to go hunting in. Because you always want to look your best when killing a demon, right?

As Jace was walking towards the library to pick out a new book about demon pox, he had a brilliant idea! Ever since the other day when Clary had taken him to a mundane club so they could "act like a normal couple," instead of hunting demons all the time, he has wanted to try this, but no one could find out about this or he would never live it down. Ever,

He quickly walked to his room and looked under his bed. Grabbing the case he had hidden under the frame so no one could find it, he inserted it into the CD player and pressed play and turned it up all the way. Slowly the room filled with a song that just spoke to the very depth of his soul.

I'm bringing sexy back

Them other boys don't know how to act

I think you're special, what's behind your back?

So turn around and I'll pick up the slack.

By this point Jace had thrown of his shirt and was left barefoot in just his jeans slung low on his hips. Singing loudly he moved his hips as he twirled the shirt over his head like a lasso, wailing the song for all he was worth. He pumped his hips in the hair and ran his hands down his abs.

Dirty babe

You see these shackles

Baby I'm your slave

I'll let you whip me if I misbehave

It's just that no one makes me feel this way

Jace continued to dance, twirling around and bending over while smacking his ass. Completely lost in the song.

Then suddenly the music stopped.

Jace froze in in terror, wishing that the CD was just messing up and no one was there. Slowly Jace turned around to see his little red headed girlfriend staring at him in amusement pressing the pause button and holding her phone up.

"Clary! Uh, ummm, h-how long have you been here?" he stuttered out while trying to look nonchalant.

"Oh I was here long enough. " Clary smirked. "And I have it all on camera. I'll have to admit at first I was a little shocked seeing you dance to Justin Timberlake, but I knew I couldn't miss this opportunity." Hitting the save button Clary placed her phone in her pocket.

"Clary, don't do this. It doesn't have to be this way." Jace pleaded, desperation clear in his voice.

"I'm sorry baby, but it does. I can't keep this to myself. That would just be cruel Jace." Before he could react Clary was running out the door into the hallway and down the stairs where everyone was waiting. She had texted them as soon as she saw her big bad boyfriend dancing around his room like a teenage girl.

Completely forgetting about his state of dress, Jace chased after her.

"Get back here Fray!"

By the time he reached the first floor Clary was standing in the middle of the room with Alec, Simon, Izzy, and Mangus standing around her. They were all laughing at what was playing on Clary's phone.

"Oh no," Jace whispered in terror.

As soon as he said this they all looked up at him and immediately started laughing harder. Tears where streaming down Isabella's face and Simon was doubled over laughing so hard he almost fell over.

"Oh my God Jace I didn't know you could dance so well," Simon remarked.

"You know you could make good money dancing like that Jace," Mangus told him. "But of course you would need more glitter.

To this day when ever that song would play they would all look to Jace and immediately bust out laughing.
