A/N: Once again, please keep an open mind!

Just as an added note, bisexuality is a completely normal phenomenon in humans (and other animals, even). My older brother studies psychology in college and he explained it all to me. :) Apparently his professor told him that most people fall somewhere on the bisexuality spectrum: even if they're 97 percent straight, there's still a little bit of wiggle room if they find the right person. And that's where I'm approaching this story from. Basically, in the universe of City of Desire, Jace, Clary, Evangeline, and Simon have always been a little bisexual, even if they didn't recognize it.

So this chapter is dedicated to all my wonderful bi friends! :D

Chapter 29

(Simon POV)

Jace and I had realized at some point that we had unfinished business with each other, so we decided to spend the day together at the Institute. I was getting increasingly confused about everything—my feelings for Clary, my growing attachment to Evangeline, and the strange attraction I had for Jace—and I knew that he felt the same way, so it seemed like spending time together would be the right thing to do.

I met Jace at the Institute early in the afternoon, and he cordially invited me inside. As I looked around after stepping in, I remembered how I once was unable to enter due to my being a vampire. But ever since I became the notorious Daylighter, I could enter the Institute without trouble.

"So, Jace," I said as we walked down the hallway towards the elevator. "What's the plan for today?" I glanced over at him, but only saw him blandly looking back at me. His golden hair was characteristically messy and drooping in his face, and I was abruptly tempted to brush it back. The thought made me blush, and I made sure to look at anything I saw, except him. "Where are we even walking?"

"I don't know," he said back, sounding faintly surprised that I had asked. "I'm just walking. Why are you following me?"

"Because you invited me over! And you live here. I assumed that you know where you're going in your own house." Involuntarily, my eyes rested once again on Jace, who now had raised an eyebrow at me while smirking a little. I felt my ears heating up.

What was happening to me? I had known Jace for ages. It was obvious from the beginning that he's a handsome guy, but I'd never been affected by his presence like I was now. Well, up until a few days ago, anyway, I thought, which embarrassed me. Maybe going to the Institute today had been a mistake…

I noticed that he was staring back at me through bemused golden eyes. He said nothing for a moment, and stopped walking. He seemed to be thinking something over, and I waited impatiently. Finally, Jace announced, "Fine. We're going to the music room," and took off walking in the opposite direction.

"The music room?" I echoed, struggling to catch up. Jace walked really fast. "Okay. What are we going to do in the music room?"

"I feel like playing piano." I had never seen Jace play before, although Clary had told me that he was good at it. This would be interesting…

"To the music room, then," I acknowledged with a nod. Jace must have been amused, because he bestowed a huge grin on me. I felt my stomach clench a little in response. This'll be very interesting.

It turned out that Jace was an excellent pianist, which didn't surprise me at all. Seeing him on the piano bench, his fingers dancing across the keys in quick succession, made me reconsider my own musical talent at the bass. I wasn't the greatest, that was for sure, but I was capable. Jace at the piano was practically its own work of art by comparison. I found myself fixating on his long, skillful fingers.

All of a sudden, he slammed his hands down on the keys, which made an unpleasant, discordant sound, and stood up from the piano bench. "Alright, Simon. Now I'm going to teach you how to play."

"What?" I gaped. "Me? Why?"

His hands found my shoulders and steered me until I was sitting on the piano bench that Jace had just vacated. "Because everyone should know their way around a piano. Come on, it's really simple." Now he was standing behind me, very close behind might I add, and he reached over on my left side to touch the piano keys. He began playing a melody I easily recognized as Mary Had a Little Lamb, then stopped after the first verse. "Your turn."

I hesitantly reached out my own hand and pressed a key at random. "There."

"No, like this. Here." Jace's right hand now came up on my other side and played another verse an octave higher. But all I could think about was how I was trapped between his long, muscular arms… "You try." I was paralyzed as I sat on the piano bench, very aware of Jace's presence surrounding me on three sides. It's like I'm a peninsula and Jace is water, I thought stupidly. And was it just me, or was there sexual tension? "Simon?"

"Huh?" My glasses were slipping down my nose a little as I turned towards the source of Jace's voice, but I didn't move to push them back up again. Because I was now face-to-face with Jace, our heads not far apart due to his leaning and my sitting. His hands were still resting on the piano. My breath hitched, and I was tempted to kiss him.

I briefly contemplated what would happen if I did, but dismissed it. Fuck it, I thought salaciously, throwing caution to the wind and pressing my lips against his.

I felt a tremor run through Jace, probably from surprise, but the next thing I was aware of was him passionately kissing me back. I was still sitting on the piano bench, my torso kind of twisted awkwardly, so I swung my legs around until they knocked into Jace's as my fingers found his hair.

Jace groaned slightly against my lips, and I shivered against him. It was like we had just picked up from where we left off in the closet during Seven Minutes in Heaven—minus, of course, the closet and the seven minutes. Daringly, I stood up while lightly pulling Jace's bottom lip into my mouth. It was great, like my mouth was on fire or something.

I didn't even know where all of this had come from, just that it was now here and potent and kind of amazing. Was this why Clary kept going back to Jace, and why he had even wormed his way into Evangeline's heart? If so, I could sympathize with them. Jace was a great kisser…

Our mouths still probing each other's, Jace began backing me towards the other side of the piano. He's not going to push me onto the back of the piano, is he? I semi-worried. I didn't know how I felt about it if he was.

And because it was Jace, I did register that he was pushing me onto the back of the piano. The hard, smooth surface pressed up against my shoulderblades, and it was actually very erotic.

I wanted more of him, all of him. My one hand migrated from his soft, curly hair down to the edge of his T-shirt, which I began toying with. As our tongues fought for dominance, I sneaked under the hem and drew my fingertips across his defined abdominal muscles. He gasped, and I took it as a personal victory of sorts.

Spurred on by the thought, I started the process of removing Jace's shirt for him. His eyes fluttered open, regarding me quizzically, but he didn't stop me. In fact, he even let me remove it completely, even though that meant we had to stop kissing for an instant.

All I could do was stare up at him, at the thin white lines crisscrossing and swirling around on his impressive physique. And I saw that he was looking back down at me, his pupils completely dilated and eyelids hooded with sexual interest. He bent down to press a quick kiss against my lips, and removed my shirt as well with a giant smirk. I decided to revise my original opinion, forged long ago, that his smirk was obnoxious. Because really, it was sexy as hell.

Then we were kissing again, our mouths open and hearts beating rapidly. Jace's tongue was now running across my teeth, sending weird sensations through my mouth, and…

"Shit," he suddenly swore, pulling back a little. I noticed blood dripping from his tongue, and realized at the same time that my fangs had unsheathed.

"I'm so sorry!" I said quickly. "Are you alright?" I licked my fangs reflexively, and instantly registered the heady taste of Jace's blood. Strangely, that only made the situation even more stimulating to me. I am so weird, I thought half-guiltily and half-turned on.

"Yeah, I'm fine." Our gazes met, and I could tell that we were both thinking of that one time I had almost killed Jace by sucking his blood. His delicious, hot blood… I squirmed, just thinking about it. "Tell me, Simon… Are you thirsty?"

"Maybe. I don't know." I was having trouble thinking straight, what with all the sensations. If I did drink Jace's blood, would I even be able to stop? I nearly hadn't last time. And then there was the matter of us making out.

Jace's look of puzzlement changed into his smirk again, and he leaned down to hover just above me. "Here," he said, and held out his tongue.

I saw two drops of bright red blood on the pinkish-red organ, and instinctively kissed him again. Except this time, I was picking up two small trickles of blood from his tongue. Why had I never tried this before with my girlfriends? All of my kisses with them were so… safe. Jace wasn't safe, not by a long shot.

His hand was just starting to snake towards my pants when we both heard someone coming up the stairs a little down the hall.

Jace extricated his tongue from my mouth and managed to stand up. "God damn it! Come on, Simon, put this back on." He threw my shirt at me and I did as he commanded while he did the same. Then he dragged me back to the piano bench and forced me to sit down, mirroring our exact postures when he had been trying to teach me Mary Had a Little Lamb. Unsurprisingly, he began playing it again and saying, "It's like this, Simon. Come on. A-G-F-G-A-A-A…"

And just like that, I knew that the mood had officially been killed.

But one thing was for certain, and that was that I still had the taste of Jace on my lips and tongue and I wanted it there again. Be patient, I chastised myself. All in due time.

So when I glanced over my shoulder at Jace and our eyes met, I met his conspiratorial smirk with one of my own.

Then I was struck with worry. How on earth are we going to explain this to the girls?!
