Clary P.O.V
I was walking through the halls of the institute, just wandering aimlessly when I heard it, the sound of music. As I got closer, I recognized it as the song "Sexy and I Know It" by LMFAO. I'm sort of confused as to who could be listening to it, but I giggle and keep walking towards where the music is coming from, when I realize it's coming from Jace's room. I stifle another giggle and open his door slightly. As soon as I looked I gasped and whipped my head away. Jace was NAKED and whipping his shirt around while dancing to "Sexy and I know it". I turn back around and take another look, hoping maybe he's dressed, but he's not. I decided to finally speak.
"Jace, WHAT are you doing?" I ask, trying not to laugh.
"Uhm… You see… Well… I was bored… and… Well, I was changing clothes and this song came on, and…. Oh nevermind." He sputters out while blushing and covering his…. Well you know.
I start laughing. Hard. I have to lean against the door frame because I'm laughing so hard, and meanwhile Jace just gets even more red. He finds a pair of boxers and I turn my head while he puts them on.
"I have to go find Alec and Izzy. They HAVE to hear about this!" I giggle and turn around and shut his door, and head off to find whichever sibling I could get to first.
