Jace was sitting awake in his bed starring at the blank wall but seeing the dream he just had flash before his eyes as if it was still happening. He could handle the nightmares he thought. He could handle being ripped in two by guilt but he couldn't handle wanting something so badly that it becomes a necessity for survival and having that one thing be Clary's dim-witted, downworlder, sidekick.
Jace was going crazy. That must be it. That was the only thing that could explain why he couldn't stop thinking about the night he had let Simon feed from him and how good it felt when he did. His inner monologue was briefly interrupted when he heard familiar footsteps walking down the hall. Alec was home, which meant he wasn't at Magnus's. Knowing this was his only chance Jace sprang from his bed and quickly got dressed before leaving the institute.
When he got outside Jace realized that he somehow had let morning sneak up on him while he was sitting in his room. He was let into Magnus's building by an elderly man who was leaving when he got there. He knocked on the door and Magnus immediately answered probably thinking he was Alec. When the door swung open Magnus's cat eyes showed surprise but only briefly then he let Jace in and offered tea which Jace declined.
"So Jace what is it the institute wants from me now?" Manus asked sitting down on the chair opposite from Jace. "Nothing I know of, I'm not here on institute business." Jace replied. He could only imagine what Magnus read from that. "Oh personal call then, haven't I done you enough favours yet?" Normally Jace would come up with some kind of witty sarcastic retort but he came for answers not small talk. "I've been having these dreams lately." Jace didn't know where to start or if he could even tell Magnus everything. He had never had this kind of problem before. He had never had dreams about someone like this before.
"There are some things about your life I really don't need or want to know shadow hunter." Jace didn't even acknowledge the comment. "What do you know about the after effects of a vampire feeding on someone?" Magnus raised an eyebrow in curiosity. "Is this about that vampire boy?" Jace nodded. "Simon. I can't stop thinking about him biting me." Magnus smiled and Jace looked to his feet. "Is that what you're dreaming of?" Jace just nodded again not wanting to make eye contact with the sparkly warlock. "Do you want it to happen again?" Jace had to think about that did he want to do it again and if he did what would that mean?
Unfortunately he wasn't able to finish that train of thought as his phone started ringing in his pocket. It was Clary, she wanted them to all go out and do something together as a group. Jace didn't even bother containing a groan of annoyance, the only group outings he enjoyed were shadow hunting. She gave him the address of some coffee shop and he left Magnus's with more questions than answers. A block away from the coffee shop Jace got a text message from Magnus. To answer your question vampire bites can be extremely pleasurable when not forced on their victims. Did yours feel good? Jace considered not replying but he knew that if he didn't Magnus would twist it to mean something other than that he didn't want to tell him. So stopping just outside the coffee shop he replied. You have no idea. It was better than sex.
When he walked into the coffee shop he noticed everyone was already there. Iz and Clary were sitting in a corner talking in hushed voices and Alec was ordering at the counter. Jace was relieved to not see the object of his recent torment and went to sit beside Clary. A few minutes later Alec sat down with two cups of coffee, passing one to Jace. Jace gave Alec one of his if you don't know him you wouldn't see it smiles and went back to listening to Iz's story about her latest 'boyfriend'. Pitching in snide, teasing remarks where he could.
All in all Jace was okay with how the day was going. That is until he heard the door open and not much else as a certain Daylighter walked in. Clary moved over as Simon pulled up a chair, putting him right beside Jace. Jace's gaze couldn't help but linger on Simon's mouth. Jace's phone lit up with a text from Magnus. It as if he knew exactly what Jace was thinking. Be careful Nephilim. These kinds of things tend to ruin friendships.
Jace choked on his coffee, which spurred on multiple inquires as to his well being. But all Jace could focus on was the one person at the table who said nothing. Chancing a glance at Simon he noticed how tired and well hungry the boy looked. Simon looked over at him and they made eye contact for a brief moment before they both quickly looked away. Jace shrugged it off and went back to focusing on the conversation. It was another hour before Jace could escape back to the institute.
-Later that night-
Screw it, Jace didn't care anymore. He couldn't prolong his agony. He didn't care if it was wrong or if it would ruin their friendship, not that they had much of a friendship to begin with. As he made his way through the dark back alleys of New York everything was quiet. It was late but he knew Simon would still be up, debating over whether he could last another day without drinking. But from what Jace saw earlier he couldn't.
Jace climbed up to the ledge outside the window in Simon's room. He saw Simon tossing and turning in his bed clearly still awake, though not without a lack of trying. He slid the window open and silently climbed through. As soon as his feet hit the ground Simon shot up out of his bed ready to fight the intruder. Jace smirked as he got a nice long look at Simon standing before him in a poor fighting stance completely naked.
"Shit!" Simon grabbed the blanket from his bed and wrapped it around his waist. Jace just continued to stare thinking that if he had still been human he would probably be blushing. "Jace why are you here, in my room?" Jace walked towards Simon, backing him up to his bed. "You're hungry, aren't you?" It wasn't really a question as they both knew the answer and it wasn't what Jace was actually asking. "You mean you want me to...your..." Jace brought his hands to Simon's waist. Slowly grazing his fingertips up Simon's abs, not as well defined as his own but more than he would have thought, he stopped his hands on Simon's chest and with a light nudge Simon fell backward on his bed.
Jace sat down beside Simon and pulled his sleeve up to his elbow and held his wrist out to Simon. "It's okay, not like you haven't done it before." Jace reassured. Simon grabbed Jace's wrist with both hands and brought it to his lips. The anticipation was killing Jace. The only thing his trained mind could register was the feel of Simon's lips on his wrist. Then he felt the sharp pain of two fangs piercing his skin. The pain soon faded and all he was left with was a pleasure that was unrivaled by any other.
Jace almost whined in protest when Simon dropped his arm but was cut off when Simon brought their lips together in a passionate kiss. Simon took advantage of Jace's surprise by deepening the kiss and easily taking control. This hadn't been what Jace had come there for but he had to admit despite his lack of experience Simon was a very good kisser and being able to taste his blood on Simon's tongue was an added bonus.
They broke apart long enough for Jace to take his shirt off and push Simon down on the bed. Straddling Simon's hips Jace leaned down for another searing kiss. Breaking the kiss Simon's lips trailed down Jace's neck, licking and sucking until he reached his pulse point. Then before Jace could even comprehend what was happening Simon's fangs sunk into Jace's neck.
