Simon and Jace didn't talk about what happened after but it was clear for both that it had to die there, in that room.

The vampire, no matter how much he tried, couldn't get rid of that video. The most he did was remove it from the camera and leave it in a safe file on his computer. Every once in awhile, on bad nights, he would rewatch it and Thor forgive him but Simon couldn't resist it, unable to convince his own body that what it was watching wasn't healthy, wasn't natural and was wrong in so many imaginable ways that he couldn't even think.

Every time he saw Jace's blood spreading in the screen it was like all those sensations came back at once, he could almost feel his sweet and lukewarm taste on his lips. It was still alive in his memory how the shadowhunter reacted to it: wild, hungry. The son of a bitch liked it. And Simon liked it just as much.

In any case, fortunately, both barely saw each other though Simon knew through Clary that Jace had spent the last few days more quiet than normal. He didn't hear about any trouble the other had gotten into and that yes was surprising. Simon had the wish to contact him and understand what the hell was happening but thought better as he still had too much self-respect for it. Jace wasn't his problem; he didn't care about anything and thus Simon shouldn't care about him either.

At least that's what he thought as he grabbed his phone and sent a text message to Jace.

Simon had already lost his dignity had been a while now anyway.

In one way or another, it was late in the night when the vampire heard suspicious movements outside. The vantage of having his senses sharper than normal was that almost nothing catches him by surprise. Jace had reached the knob of the window at the same time that Simon unlocked and opened it. The two almost bumped face-to-face into each other.

"No fun," Jace murmured without moving away, his face inches away from Simon's.

"Your Shadowhunter abilities are no match to my vampiristic superpowers," he said, smiling and pulling Jace in.

"Superpowers? Ha ha, loved the joke," Jace replied, sitting down in Simon's desk chair and touching distractedly his things. Jace used mundane clothes again, looked like he had made it his habit changing his Shadowhunter uniform for jeans and a t-shirt. "So? What do you want?"

"To talk," he answered sincere.

"Talk? Really?" Jace was skeptical as of the Vampire's intention. He pushed away his shirt's neck and put his hand on the bite mark that was there. "Thought you were up to get another bite out of me. I know I'm delicious."

Simon couldn't stop himself from looking at that specific place in Jace's body. But, he licked his suddenly dry licks and forced himself to focus on the other's golden eyes.

"I'm sorry about that."

"Don't apologize, if I hadn't wanted it I wouldn't have let you anywhere near."

"But… But I could not have stopped," he pointed. It was one thing was to suppose Jace was crazy enough to want his blood to be sucked, another was to hear it from his own mouth.

"I would've made you stop, mundie," he answered, tired. Only now Simon noticed that Jace's eyes looked deep and his face lightly haggard. "It happens that…"

"Happens that…?" Simon encouraged, noting Jace didn't seem willing to elaborate more than that.

"It happens that I don't know what I want anymore," he said, as if that phrase explained everything. "Do you still have the video?"

"What? What does that have to do with it?"

"I just got curious to know who won." Jace gave him a smirk and changed seats, going from chair to bed and gave the space near him two small slaps. "I want to see."

If Simon could blush, he would've already changed to purple at this point. He cleaned his throat.

"I don't think that's a good idea."

"Mundie, I know you don't get tired and could stay standing there with that buttface for the whole eternity, but could you get the damn laptop, sit here and show me that cursed video?" Despite his words, Jace's voice wasn't all that aggressive. Simon knew he would regret this, but someone needed to have a little more common sense in this story.

"No."

Jace narrowed his eyes and in moments like this that Simon really could see how dangerous this boy could be. All the trauma in his past, all that distorted view he had of others and, more importantly, of himself. He was instability in a body trained to be a weapon since childhood. Simon, being a vampire, didn't have it much better than him in relation to stability but, as long as there wasn't any blood involved, he was able to remember and stick to who he was.

In this moment, he didn't have a single clue what was going on inside Jace's head.

"Why not?" the Shadowhunter said, an accusation masked as question. "What's the problem?"

"You tell me what's the problem."

"You didn't seem bothered last time." Jace scanned him with his eyes and Simon suddenly felt naked, despite the many layers of clothing he wore.

"I wasn't being myself last time," he replied and raised his chin, watching as Jace got up and walked in his direction, the look the boy was giving him was so intense it felt like it was capable of making a hole in his head.

"And you wouldn't like to do it again? Stop being yourself for a while?"

Simon opened his mouth to answer, to let it be clear that he wouldn't do it. That he wouldn't be used as an escape mechanism, a way to runaway, someone that Jace that permission to hurt and lose control without worrying about the consequences. He wanted to say that he wouldn't offer moments of numbness in exchange of blood. But Jace was faster, as he always was. A small knife appeared to practically materialized itself in the palm of his hand and he showed it like he presented something very valious.

"I don't think you're that cheap, mundie," he said, using the nickname for the mundane that he never really stopped saying and reading Simon's thoughts like he was an open book. "It's a choice I'm giving you. Do you see?"

And Simon was seeing well the silver and sharp light of that piece of blade, so close to the calloused skin of Jace's hand. He swallowed dry, feeling his body answer immediately to the possibility. Of course Simon didn't need tools to hurt or get blood from him, but the idea of doing it little by little, in way both precise and elegant, made Simon drool.

Again, his vampire side spoke louder. His non-human part desiring things he would never consider before. And he wasn't just talking about blood; if he were still playing the boner challenge, Simon would lose gladly.

"Are you mad?" questioned, his voice huskier than normal and, though his tone was indignant, he took a step closer, getting near the temptation. He never said he was strong. "Do you want me to hurt you?"

"I want to feel something," Jace answered, almost exasperated, his eyes shining like never before, "and—don't boast, mundie,—but there isn't a lot recently that makes my system go."

Simon widened his eyes slightly, incapable to believe it really meant something to Jace Wayland.

"Do you want to do this or not?" the blond offered again, showing less patience and the usual insensitive mask that he wore so much already back in place. And Simon, following his instincts and ignoring completely the few rationality he still had left, took the blade from Jace's hand carefully, as a way of mutual acceptance. The blond nodded his head and waited.

Maybe he didn't have so many problems with being an escape if the payment was to see Jace—who was always so sure of himself, always so superior,—in a state of vulnerability, putting his body at his will like that.

"Since we agreed to do this… I want to make some things very clear," he said, closing completely the distance between them and staring at the challenging eyes of Jace, their mouths almost touching, provoking each other as if a kiss was inevitable. But not yet, Simon thought, thinking a kiss would be too personal for what they were doing. He felt Jace's warm breath touch his cheek and smiled, holding the bar of his shirt forcefully and feeling the blade's weight in his hand as he positioned and started cutting the fabric, from the bottom to the top, slowly. "One, it will be my way..."

Jace huffed as the knife found the thick part of his shirt's neck and went dangerously close to his face before, at the end, ripping the fabric. He let the clothing fall through his shoulders, revealing his worked chest, his marks, his body hair sticking up and his hard nipples. Simon leaned in and started spreading kisses on the region of the neck and shoulder of Jace, making sure to take his sweet time with the scars he had left, licking and scraping with his teeth, teasing. He wouldn't bite at that moment, for the expectative for what was coming later was enough to give him some control.

"Two, you need to trust me." His hands, that explored the hips and back of the other, went to the waistband of his pants, playing with its extension before starting to undo his zipper. Simon lowered it until the knees and Jace did the rest, finishing taking it off with kicks together with his shoes. His penis was painfully hard under one of his traditional black boxers. The vampire removed it with care and soon there was a naked Shadowhunter in the middle of his room.

Simon glued their bodies together once again, appreciating the sounds that came from Jace, making him back down and sit back at the chair that he had been not long before, when he first got there. The height difference between them made Simon's mind wander for a few instants,—imagining Jace sucking him off, his wet red mouth around his member,—that he ended up just as hard as Jace in that moment. He let the air out with a sigh and noted his fangs were out, preparing to sink in someone's fresh meat.

"Three; no matter what I do, if it puts your life in danger," he started, staring down at Jace's dilated pupils, "stop me."

He saw the other swallow dry and nod.

The answer, for now, was enough for him. That wasn't in any hypothesis safe, but Simon was counting with Jace's capacity of using his stele to heal himself. All he could fear was entering frenzy and not being able to stop.

He picked up the destroyed shirt from the ground and pulled two ripped pieces from it.

"I'm sure you're able to escape from knots, if you want," he said as he tied the other's wrists to the chair."

Jace tried out closing and opening his wrists. He smirked.

"I thought you were taking this seriously, Lewis," he commented, sarcastic.

"Ah, I am." Simon ignored his tone as he kneeled in front of Jace. "I guarantee to you I am."

He saw as the man held his breath at the first movement of Simon with the blade, positioning it near the internal part of his thigh, travelling from his knee until it was dangerously close to his erection and to the sensitive skin near it. That was strangely hypnotic, Simon barely noticed his free hand clenching around Jace's other leg with more strength than necessary.

At some point the vampire allowed a cut to open sob the pale skin and a line of blood emerged and ran down the thigh. Automatically, Simon got closer and started sucking it with greed, not wanting the liquid to take away his focus from what really mattered that night. He abandoned that leg and went to the other, not without looking up and cleaning the knife with his own tongue. He could see Jace arching back, his neck exposed and eyes closed. He also saw the precrum coming from his member and decided it wouldn't take long to give it the deserved attention.

The next cut was more direct and deeper, hearing the wave of moans as he dived right in that blood and he wasn't surprised to notice it was a mixture of his own desire with Jace's, that was starting to become inquiet in his chair.

"Ah… come on, mundie," he whined and Simon pretended to not have heard it, trading the hungry suction for provoking kisses on top of the cut, getting near on purpose of Jace's erection and backing out deliberately from it right after, "please…"

The blond looked down, his eyes almost completely black now, and bit down his inferior lips. Simon could only imagine the scene he was seeing in that exact moment; a pale and skinny boy, with teeth incredibly bigger than normal—sharp and pointy—covered in blood. Moreover, his entire face should probably be bloody, just like his hands and clothes and, to top it all, a nasty smile on his lips, delighted at the fact that no matter how monstrous that scene was, it turned Jace on like hell. Simon could see and feel, the tip of Jace's penis touching his still closed lips, the viscous liquid that came out from it mixing with the red already there. He was full of Jace in that moment.

Simon left there a chaste kiss and almost openly smiled at the Shadowhunter's movement against his restraints, anxious for Simon to do what he had to do. When their eyes met again a question was thrown in the air: with or without teeth?

Jace widened his eyes and Simon smiled, showing his gallery of natural weapons and letting them be seeing as they went back in.

"Bastard…!" the blond cursed, but just then Simon opened his mouth and started blowing him, relaxing his throat enough to be able to take the most as possible of Jace's member. Using one of his hands to involve the base of the penis and the other holding firmly his waist, his nails sinking in the skin during the process. If he wanted to get hurt then he was going to get hurt. The blade balanced on Jace's knee, left aside for the moment.

At the sounds of the other's moans, Simon found a comfortable pace of up and down, pausing a few times to let his tongue wander through that soft and warm skin, so full of blood it was almost purple-looking. The vampire was never more thankful for his self-control than in that exact moment.

He didn't think he could hold if for much longer. His own erection was sending him shockwaves just by simply brushing against his jeans. Simon groaned and moved his hand away from the other's waist and used it to undo his pants and free his confined penis. He sighed in relief as he was able to jerk off.

Jace was starting to thrust his hips against his mouth. All of his being making it clear he was near his climax and Simon let himself for a few instants, putting his open hands over the blond's thighs and pressing the cuts with his fingers causing pain and making the bleeding worse. At the same instant, however, Jace let out the most erotic sound Simon has ever heard and came.

The vampire didn't have the same experience swallowing sperm as he had with blood and good part of Jace's ran down his chin.

There was a pause after that. Jace breathing with difficulty, with his eyes closed and hands into fists, his toes still curling. Simon cleaning his mouth and chin as he could with the sleeve of his hoodie and didn't know what to do next. He wasn't exactly tired, but he asked himself if his work was done. Everything worked around that child of nephilim, after all. So he let his head hang and lean on the knee opposed to the one with the knife, his face only a few inches away from the cut still bloody.

"You can let me go now," Jace said, still huffing and Simon didn't make much effort to raise his arm and cut the stripes of cloth with the knife. After all, he was who ended up exhausted. And Simon was the one felt sucked dry.

Jace, in the other hand, had other things in mind and barely freed himself and had already snatched Simon's face with his two hands and brought him closer, the kiss that Simon had refused to give was there, waiting, and he couldn't help but let out a pained groan, one that spoke both for his surprise, relief and doubt. Instead, the boy digged his hand in Jace's hair, keeping him in place, the sudden sensation that everything would be nothing but a dream if their lips were to stop kissing.

But, of course, Jace had to breath.

The chair didn't offer an agreeable position anymore and so the Shadowhunter prompted Simon to stand up, kneeling in front of him and putting his hands in his hips. He didn't seem bothered with his wounded legs.

"I don't like being unfair," he said, right before lowering the other's pants to the knees and jerking him off for a few instants before putting the hard member in his mouth. The fact that Jace was clearly inexperienced at sucking dick didn't nothing to stop how turned on Simon was, on the contrary, the sensation of being inside Jace in some way was almost too much for him. It was hard to concentrate with the spasms sent by the the other's throat sending him waves of pleasure to his spine and stay up at the same time. He leaned back a little and rested against the window, ignoring the fact that it was still open.

"Jace…" he started, his mouth so dry he almost wasn't able to finish, "I will…"

Luckily, Jace drew back with the face of who was going to ask what the hell he was talking about and, when Simon reached his orgasm, avoided choking with semen. The liquid hit his jaw and dirtied his hair instead.

"Argh, gross," Jace murmured, picking the strands of hair with his fingertips and trying to clean it with what was left of his shirt. Simon continued still, appreciating the crazy and lightening feelings that hit him as he came.

When he looked down—with Jace was now sitting on the ground, busy,—Simon noticed how much his room looked like an horror movie. He swallowed dry, more worried however with the wounds on the blond's thighs, that still bled.

He sat down too and called Jace's attention as he held his legs and opened them gently. He licked the cuts again, more to stagnate them than to consume from it. The act didn't stop being sensual, but the caress wasn't exactly erotic. Jace kept staring, without saying anything.

"You didn't bring your stele, did you?" Simon asked, without really expecting an answer, just now noticing what he hadn't seen early as he stripped him earlier. He went up with his caresses until the scarred shoulder of Jace as if the marks were still recent. He smiled slightly, sure he looked more like a lapdog licking the wounds than a vampire, a member of the downworld. "You also haven't used the iratze here. Why?"

Jace didn't answer.

"Why do you hate yourself so much?"

The blond backed away from Simon and got up, being careful to not make eye contact. He put on the pants and put his underwear in his back pockets, as if he was used to escapades like that.

"It's better if I go," he said, a lot like the last time.

"Always leaving in the best part of the party," Simon commented humorless, pointing at all the mess that stayed behind, "cleaning that's good nobody wants to help with."

Jace gave him a sideways smile and jumped through the window, disappearing in the darkness.

Simon avoided thinking in what he was getting himself into by trying to elaborate a way to hide all that blood from his mother, because he didn't have the strength to clean. If he didn't sleep and disappear from the world for a few hours Simon was sure he'd explode.
