A/N: ALRIGHT NERDS this is smut. A smut chapter. So yeah, you've been warned.

-------------------------------------------------------------------

Simon was staring and he knew it. But then again, who wouldn't? It's not like you see a half-naked, sweaty shadowhunter doing chin-ups from the beam of the ceiling in the training room every day. He could kind of relate to Magnus, when he sometimes used to pretend to come too early for their dates with Alec, just so he could catch him training. Simon stared at the blonde, who was literally dripping with sweat (and Simon wasn't drooling), his blonde hair just a little messier than usual. He wondered how long he could stand there and get away with it.

"There you are. You're late." came the angelic voice and Simon snapped out of his trance-like state. Oh, not for long, apparently. Jace let go of the beam, landing on the floor with perfect balance and fixed his posture. The sweatpants were hanging low enough for Simon to see the V-line disappearing into them and when Jace raised a hand to run it through his hair that had fallen to his face, the runes on his skin moved as the muscles did. Simon realized he hadn't said anything, so he cleared his throat. Think very normal thoughts, Simon, think of... think of cars. Yeah, cars. That are vehicles. Just like bikes. And bikers wear leather jackets. And Jace wears leather jackets too- he looks so fucking hot in leather, though. Better even without it. 

Oh, fuck, wait, no. Simon felt himself grow hotter by the second. Oh, for fuck sake.

"Earth to Simon? You gonna go change or what?" Jace waved a hand in front of him and Simon realized that A. he had been quiet for an embarrassingly long time now, and B. Jace was standing very, very close to him. Simon could see his mismatched eyes watching him in amusement and could see the small trace of sweat dripping from his chest over his flexibility rune...

"Um, right, I'm going. And I'm not late. You said 3." Simon rambled, getting himself together (-ish). Jace smiled at him (fuck) and leaned over to the bench beside them to get the water bottle. "Yeah, that means you should be here at 2.45. It's an unwritten shadowhunter rule." he said, taking the cap off the bottle. Simon eyed him, now feeling a little frustrated (from oh, so many things). "I was a vampire not that long ago, so I'm really not familiar with 'shadowhunter rules', if that's even a thing, especially not the unwritten ones." he said to the blonde, his tone a little snappy. Jace drank two big gulps and tossed the bottle away, raising an eyebrow at him. "Ah, do you want me to write notes for you? Little post-it's on the fridge so when you come to the Institute, you could read them? 'Rule no. 1 - don't piss Jace off or he'll kick your ass.'" he said, now smirking and crossing his arms.

Simon rolled his eyes. "Yeah, how about 'Rule no. 65 - wear a frickin shirt sometimes.'" he mumbled as he walked to the changing rooms. "What was that?" Jace called after him but he hastily escaped the blonde, trying not to be too freaked out about the fact that Jace was about to train him. He had hoped he would get over his gay panics when around the shadowhunter, but apparently, Jace knew about them. Isabelle was a great big fat traitor (Simon still loved her), and had spilled the beans and now Jace flirted with him - a lot. But Simon never did anything about it (except panic the fuck out). He figured Jace was just teasing him and he hoped it would pass, when Jace finds another interesting toy to play with (last month it was another Seelie, you'd think a guy would learn after Kaelie). 

But it was very, very had to concentrate, when Jace acted like he really did want Simon. It made the brunette feel very... uneasy. And way too excited. He was very exclusively and royally fucked.

And you got me like, oh
What you want from me? (What you want from me?)
And I tried to buy your pretty heart, but the price too high

He changed into his tank top and sweats and grabbed the bottle of water. Here goes, he thought to himself. When he exited, Jace was leaning on the wall, typing on his phone. When Simon showed up, he discarded the thing and propped himself up again. "Alright, we're starting with the basics, hand-to-hand and then we can use the bo staffs." Jace was saying and Simon nodded absentmindedly, eyeing the way Jace moved towards the floor. "Any day now, Simon." Jace said, smirking and letting his name take the emphasis in the sentence. The brunette tried to ignore it and let his mind go as blank as it was possible. He took his stance and Jace didn't even correct him. "Good. Okay, whenever you're ready." Jace said, showing him to advance. 

Simon breathed in, trying to not stare at Jace's eyes, and took a few steps forward, hands raised. He aimed for his shoulder, but missed when Jace quickly moved away and caught his arm. Simon wiggled free and made his move - he pretended to throw a punch towards Jace's head and when the blonde moved to block it, he hit him in the chest, making them break apart again. Jace smiled. "You're a quick learner, Simon. Clary's done a good job. But, she's not me." Jace said and he moved against Simon so quickly, the brunette had no time to block him. Suddenly, his arms were pinned to his sides and he felt Jace behind him. His breath tickled his ear. "Now what?" Jace asked, amused and Simon panicked instantly, feeling the blood rush in his veins down to somewhere he really didn't want it to go. He punched the blonde with his elbow and twisted around, sweeping Jace's legs from under him. The blonde fell down and Simon smiled triumphantly. 

"That's what." he said cockily and tilted his head. It was a mistake, letting his guard down, of course. Jace was quick as lightning, kicking his feet from under him and pinning him to the floor, knee on his throat. "Fuck." Simon breathed out and Jace smiled. "Always make sure that when your opponent is down..." he got up, reaching out a hand to Simon "...they stay down." he finished. Simon grunted, taking his hand and pulling himself up. Jace went to the staffs and picked up two, tossing one to Simon. "Alright, Clary said you need to work on your defense. So I'll be attacking you and you show me how you defend yourself. Don't leave yourself vulnerable, move your feet all the time and..." Jace said, flipping the staff in his hand and smiled, making Simon swallow "... pay attention." the blonde finished. Simon felt himself panic again. This will never work, Jace was just so-

He raised his staff when the blonde jumped, attacking him from the air. Simon fell to his knees, blocking it and then stood up again, pushing Jace away. They clashed together again and Jace sweeped the staff under his feet, but Simon saw it coming. He jumped, avoiding being knocked down again and aimed at Jace's back, successfully hitting him. Jace turned, his eyes glinting and there was a slight flash of gold. Simon got distracted and Jace advanced, his movements a blur and Simon backed up, until he hit a wall. Jace twisted his staff with Simon's, making it fall from his hands and Simon found himself pinned against the wall by Jace's weapon, that he held against Simon's chest. They were both out of breath slightly.

Baby you got me like, oh, mm
You love when I fall apart (fall apart)
So you can put me together
And throw me against the wall

"What happened? You got distracted." Jace said, but his smirk and his eyes gave away the truth - he knew very well why Simon had lost his defense. "Maybe I should make another note? Rule no. 56 - never think dirty thoughts about your trainer, you'll lose.'" Jace said, his face impossibly close to Simon's. He could see the beads of sweat on his forehead, could feel his breath on his face and he could see the speck of brown waver in a golden shade when Jace smiled at him cockily. "Jace, fuck off." Simon groaned, trying to move. He wasn't going to deny anything, it'll only give Jace more to tease about. Jace didn't budge. "Why?" he asked simply, still smiling. Simon saw Jace's eyes roam him from top to bottom. When his gaze came back up, the blonde's smile wavered. "Because-" Simon started to say, but Jace stopped him. "Shut up, Simon." he said sternly, making the brunette close his mouth. 

He felt his heart beat frantically in his chest and his mind was foggy with thoughts of Jace and his proximity and the way his hand was on his hip- wait what? He almost passed out when he realized where the blonde's hand was. With the other, Jace threw away the staff and Simon felt Jace's other hand push him further against the wall, the palm on his chest and then Jace was kissing him.

Like, really kissing him. His tongue went into Simon's mouth and the brunette couldn't hold back the moan he'd been keeping in, and all the feelings came rushing back. His legs felt like they might give out and the desire in him raised its head again. He kissed Jace back, almost like an instinct and he felt the blonde's hand against his chest roam down to his stomach, raising the tank top and then he felt Jace's fingers on his skin. Simon's hand went into Jace's hair and he tugged at the strands, hard. Jace made a noise that went straight into Simons groin and he felt Jace's leg move between his, brushing against him.

He gasped and pushed Jace back suddenly, realizing what was happening. Jace was surprised, to say the least, and his eyes stared at him in question and disappointment. Wait, what?  "What are you doing?" Simon asked weakly, out of breath. Jace gave him an incredulous look. "There's this thing called kissing that two people do, when they want to-" Jace started sarcastically and Simon shook his head, rolling his eyes. "No, I mean, what are you doing?" he asked again, raking his hand through his hair. 

Baby you got me like ah, woo, ahDon't you stop loving me (loving me)Don't quit loving me (loving me)Just start loving me (loving me)

Jace eyed the movement, taking a step towards Simon again, shortening the distance. Simon's heart was pounding and he was very well aware of the reaction Jace caused him in. And he felt panicky and embarrassed. "I am- was- kissing you." Jace said again, his face now clearly annoyed. "Yes, I mean, why?" Simon said then, feeling like he wanted to flee. This didn't make any sense. "Because you look hot in your training clothes and covered in sweat, panting against the wall, where I have pinned you to-" Jace said, his voice low and seductive, making Simon's skin tingle and his heart stopped "-although, it would've worked better if you'd just take off the shirt. I mean, it's only fair." the blonde continued casually, motioning to his own bare chest. Simon shook his head, still not understanding. Jace didn't like him like that. At least, he wouldn't do anything about it. Well, until now.

"But you don't- we don't-" he was trying to say and Jace smiled, closing the distance so they were almost chest to chest again. "We don't what, Simon?" he asked and the brunette felt his breath hitch as Jace leaned closer, kissing his neck softly. He tried to suppress his moan. "Ah, so this is why Alec and Magnus decided not to train together." he said randomly and Jace chuckled against his skin. He raised his gaze to Simon's and the brunette bit his lip, looking down at Jace's bare skin. "Fuck. This is coming off." Jace said, eyeing Simon's lips and moved his hands to Simon's shirt, discarding it despite Simon's protest. He didn't protest for long, though, because Jace's lips prevented it masterfully.

He felt Jace move further against him, the kiss so full of lust and desperation that he could've come undone, right there. He was embarrassingly hard now and he whimpered slightly against Jace's lips when the blonde brushed his hand over his erection. He could feel Jace's smile against his mouth but he didn't care. He needed to know- He let his hand go to the waistband of Jace's sweats and he lowered it, his fingers brushing over the front of Jace's pants and with satisfaction he felt Jace through the fabric. The blonde growled low in his throat when Simon's hand touched him. Jace's strong hands went to Simon's arms, holding him in place and Simon huffed in annoyance when he couldn't touch Jace. "Well, aren't you eager." Jace said, obviously enjoying Simon's disheveled appearance. Simon just rolled his eyes, feeling his cheeks warm up. "You started it. 'Rule no. 125 - never kiss your trainee, he might just fuck you'" he said, very surprised by his own confidence. Apparently, so was Jace, because the blonde's eyes widened at the comment almost comically and his pupils dilated.

He opened his mouth to say something, when they heard a clicking of heels and a 'Jace!' echoing from outside the training room.

Oh, and baby I'm fist fighting with fire
Just to get close to you
Can we burn something, babe?
And I run for miles just to get a taste

Simon very quickly pulled himself up and away from Jace, noticing how the blonde gave him a weird look. He went to sit on the bench, grabbing his water bottle and laying his hands on his lap. Jace gave him a smirk and went to the beams, sitting on it with his legs tangling on either side and Simon rolled his eyes. Isabelle came into view, with Clary right on her heels. "Jace-" Isabelle was saying and then stopped, eyeing them both. "So, this is what training looks like?" she drawled, giving them a confused glance.

"We're taking a break." Jace informed, smiling at the girls. Clary raised an eyebrow. "You do breaks?" she asked, confused and in disbelief. Jace gave Simon a wink, who died internally, and had a smug look on his face. "I do now." Jace announced and Isabelle gave Simon 'the look' and then smirked at Jace. "Oh, are those breaks called 'Simon'?" she asked and Simon choked on his water. Jace gave the girls an unreadable expression and then gave Simon a smirk, watching as the brunette struggled to breathe again. "Maybe." he said and Simon went red again. "We don't- It's not-" he rambled and Clary gave him an amused glance, stepping more into the room. "Did you need something?" Simon just gave up, sounding defeated. Jace was still dangling his legs in the air, looking very casual. The bastard.

"Actually, yes. I need to talk to Jace." Isabelle said, looking very entertained and she clicked towards the blonde, who gave her an annoyed look. "I don't have time for Clave business. Tell them to leave a message after the beep. Beeeeeeeep" he said, making Isabelle scoff. "Jace, stop acting childish. They need you to go to Idris for a mission. Alec told them you'd be the best for the job, so respect his decision." Isabelle said, giving him a stern look. Simon saw Jace deflate. "I should've known my parabatai was behind this. He never lets me have any fun. Only work, work, work. Oh, the cruel life I must live..." he said, hopping down from the beams. "When?" he asked reluctantly and Isabelle rolled her eyes, throwing him his shirt. "First thing tomorrow. Clary can train Simon in the meantime. Don't worry, Clary doesn't 'do breaks', so he'll be fairly untouched." Isabelle told him, giving her parabatai a wink. Clary giggled, watching as Simon covered his face with his hands.

Must be love on the brain
That's got me feeling this way (feeling this way)
It beats me black and blue but it fucks me so good
And I can't get enough
Must be love on the brain yeah
And it keeps cursing my name (cursing my name)
No matter what I do, I'm no good without you
And I can't get enough
Must be love on the brain

Jace gave them both a look that could kill, but then shrugged. "Fine, as long as he works on his defense. He is crap at that." the blonde stated loudly and Simon stood up. "You- what! That's not true and you know it!" he said, annoyed, but Jace gave him a smug smirk. "You should work on not getting distracted, Simon." Jace said, the innuendo clear in his voice and Simon threw his hands up, signalling his defeat. "I can't work like this." he mumbled, making the girls laugh. "If you guys are done, Clary and I want to train. But if you boys need some more alone time, we will gladly stand aside and watch." Isabelle said sweetly, smiling and Clary laughed, moving next to her. "You guys are impossible." Simon announced. 

Jace put his shirt on and crossed his arms, thoughtful. "Yeah, I'm not so sure about you watching. I mean, that's kind of weird, but hey, whatever floats your boat." he said then, making Simon groan loudly. "I am going to shower." he said and then caught Isabelle's and Clary's expression "Alone." he finished, giving them a stern look. "Oh, were you going to invite me?" Jace asked, hopeful. Clary and Isabelle both gasped and Isabelle was holding her sides, trying not to laugh. Simon was pretty sure they were going to pass out. "Jesus fucking-" he said, turning on his heel and stalked to the showers. He heard the girls giggling and talking to Jace.

Baby, keep loving me
Just love me, yeah
Just love me
All you need to do is love me, yeah

He let the warm water cascade down his body as he tried not to think about Jace kissing him. He could still feel the warmth of his lips on  Simon's, the reaction that their bodies caused in each other and his mind was racing. What the fuck happened? Was that even real? He stopped his trail of thought quickly, noticing that he was, again, getting wound up. He turned the shower to cold for a few seconds and hissed, when the water hit his skin. When he stepped out, he wrapped a towel around his waist and dried his hair.

When he pulled his ripped jeans on, he went to look for his shirt. He heard Clary call his name and he looked up. "Simon, can I come in here?" Clary asked and Simon rolled his eyes. "Yeah." he replied and Clary stepped into the changing rooms. She was clearly trying to hold back a smile or even a laugh. "What do you want, Fray?" he asked and Clary smiled. "I just wanted to say that dinner is at 6. Also, what's up with you and Jace?" she asked, eyeing him and Simon turned his back on the redhead, still not finding his shirt. "Fuck." he muttered. "Nothing's going on. And I forgot my shirt to change." Simon said then. Clary perked up. "Oh, I have one of them in my room still, from when you changed after a mission. It's clean now. And Jace said that you can have your own room, you know. All the shadowhunters live here anyway, well practically all." she said, nodding for Simon to come along.

He did, picking up his bag and feeling a little cold with his bare chest exposed. "No thank you, I'm perfectly happy at my apartment." Simon said, mentally adding 'and I don't need Jace flaunting himself in my face all the time'. Clary must've caught on to it anyways, because she gave him a sly look. "Riiight." she said, drawing out the word and Simon huffed. "Stop it." he said and Clary laughed. They reached the hallway just as Jace emerged from his room, now wearing his faded blue jeans and a white T-shirt. He was barefoot. 

Jace stopped, leaning on the doorway and he whistled. Actually whistled. "If this is the new dress-code, I'm totally here for it." he said, smirking at Simon. The brunette felt his skin grow hot again. He didn't have as much runes as Jace did, but he was still a shadowhunter now, so his runes were very dark against his pale skin and he felt Jace's eyes stop at the endurance rune. "They suit you, by the way. The runes." Jace said, his voice flirtatious and his eyes were glinting, not even bothered by the fact that Clary was right there. The redhead gave a small noise and then smirked at Simon. "You sure you want that shirt?" she asked, eyeing them both and Jace raised an eyebrow. "Nope, wouldn't bother." Jace said for him and Clary held her hands up. "You are impossible, Jace. Don't give him a heart attack, you dick." she said, patting Simon on the shoulder and moved back towards the training room.

"At 6, Lewis!" she yelled, rounding the corner. Simon stood there, not really knowing what to do with himself.

Got me like ah-ah-ah-ow
I'm tired of being played like a violin
What do I gotta do to get in your motherfuckin' heart?

Jace was still giving him a smug smile. Arrogant, son of a- "So, you still wondering why and what?" Jace asked, laughing. Simon rolled his eyes, crossing his arms. Jace stopped, eyeing his movement and Simon caught it. He smirked. "Nope, now I'm just wondering when." he said boldly and Jace blinked. "When...?" he asked a little dumbfounded and Simon was glad. He deserved it. "You mean, when will you finally get your defens-" Jace started, recovering from his slight confusion, but Simon didn't let him finish. "Oh, shut UP already." he said to the blonde. 

He wasn't sure how or when he had moved closer to the other boy, but now he was kissing him hungrily, pushing them back and inside Jace's room. Simon had been there before - it was weirdly tidy, everything had its place and nothing was ever misplaced. Jace gasped in surprise when Simon kissed him, but the brunette felt the blonde melt into it right way and his heart jumped in excitement. His hands went to Jace's shirt and then it was gone and he felt the toned muscles under his fingertips. He moved to the flexibility rune. "So, does this actually work?" Simon asked huskily, when he pulled back, tapping the rune.Jace's pupils were blown wide and his eyes scanned Simon's upper body. "Well, I don't need it, but it certainly helps." he said and Simon rolled his eyes at his cocky tone.

"Someone really ought to teach you how to not be an arrogant asshole." Simon said, pushing him down on the bed and Jace raised an eyebrow. "Huh, I guess you might be right." he said, smirking and Simon leaned into him, their skin touching and it felt like fire. The flame only grew when Simon felt Jace's hands on his jeans, undoing the button. Simon stopped him. "I don't know about you, but I'm pretty sure there are two nosy parabatais in this Institute who don't know how to knock." he said, moving away from Jace. The blonde pushed himself up and, sitting on the bed next to him, pulled him in for a kiss. Jace's tongue sweeped over Simon's lower lip and he let him in, letting Jace steal his breath away. When the blonde pulled back, he caught Simon's lower lip between his teeth. When he let go, Simon felt himself grow painfully hard, feeling frustrated with every passing second. "You might be right. I don't want anyone interrupting me this time." Jace said and got up, moving his stele across the door. Locking it and, to Simon's amusement, did a sound blocking rune as well.

He raised an eyebrow when Jace turned around. "Just in case." he winked and Simon felt his dick stir in his pants. He really needed to get them off.

Baby like ah, woo, ah
Don't you stop loving me (loving me)
Don't quit loving me (loving me)
Just start loving me (loving me)

Jace came over to him, and very quickly, pushed Simon down on the bed, kissing him, with his hand moving to Simon's hip. The other hand was on Simon's chest, tracing the runes. He moved down, kissing Simon's neck and when he reached the endurance rune, he licked it. Simon hadn't ever felt so desperate for friction before in his life. When he arched his back, their lower bodies touched and Simon let out a strangled moan. Jace bit his skin, leaving a red mark and moved his fingers to his jeans, unbuttoning them expertly and slid them off. He stood up, removing his own and Simon eyed his movement, licking his lips.

When Jace came back on the bed, he kissed Simon's abdomen and trailed himself down to his boxers. Simon was pretty sure Jace was going to say something witty at some point, but to his surprise, the blonde didn't. He just slid his fingers to his boxers and took them off slowly. Simon felt the air hit his erection and sighed in relief. Then he let out a low sound in his throat when Jace wrapped his hand around his dick, his lips inches from it. He could see Jace leaning down, licking the tip, while still holding it. Simon threw his head back and moaned, loud, when Jace finally wrapped his lips around his throbbing cock. He cursed loudly, when Jace moved his lips along his shaft and his eyes were squeezed shut. It was so intense and so much better than he ever even imagined. Jace really knew what he was doing.

The blonde released him and licked up his length while his fingers went behind Simon and over his hole. Simon hadn't felt anything in that area for a very long time, so he gasped when Jace moved over it. His eyes flew open and he saw Jace releasing his dick as he removed his own underwear. He couldn't help but stare, but Jace's eyes were still on Simon's dick. "You just gonna stare at it or..." Simon said suddenly, smirking. Jace's eyes went to his and Simon saw his gaze darken. Simon swallowed. "Oh, Simon. You have no idea what I want to do to you." Jace said, his voice dripping with lust. Simon shivered under him, when the blonde moved between his legs. He put two fingers in his mouth, licking and sucking on them and Simon couldn't look away.

Oh, and babe I'm fist fighting with fire
Just to get close to you
Can we burn something, babe?
And I run for miles just to get a taste

Jace leaned over him, his hand going near his hole while the other grabbed his dick again. Simon felt like all of his nerve endings were on fire and on high alert - everywhere Jace touched was a thousand times more intense than he ever had felt before. When Jace slid his fingers in, both at the same time, Simon hissed in pain and pleasure, both. Jace's eyes betrayed a flicker of concern, so Simon bucked his hips. "Don't you dare stop." he pressed through his teeth and Jace smirked. He leaned over, placing his lips on Simon's as he moved his finger inside him, opening him up. The kiss was a lot sloppier and they were both panting. Simon's hand went to Jace's dick and he stroked it, not gently, but hard. Jace moaned into his mouth and Simon relished the sound. It turned him on so much that he bit down on Jace's lip, drawing blood. He licked at the metallic liquid.

Jace pulled back, his eyes glazed over with desire. "Old habits die hard?" he asked, partly amused and referring to Simon's previous life as a vampire. The brunette smirked. "You like it, don't even try to deny it." he said, remembering how he had drank from Jace. The blonde gave him a deep look and then he leaned close to his ear. "You don't know what you do to me, Simon." Jace whispered in his ear while he curled his fingers and Simon gasped, arching his back off the bed. Jace pushed him back with his hand on his chest, now moving three fingers in him.

Jace moved over, getting a bottle of lube from the drawer but Simon took it from him. Jace raised an eyebrow but Simon just opened it and coated Jace's dick with it, moving his hand slowly up and down his dick. Jace closed his eyes, moaning and still moving his fingers in Simon. When the brunette was done, Jace moved fast, pinning Simon's hands above his head. Simon felt his dick twitch but he wasn't going to beg. Nope, never. Jace moved towards his hole, teasing him, the tip brushing against him and Simon whimpered, not even caring about the sound he was making now. He clenched his jaw, but Jace smiled, seeing it, and leaned down to bite Simon's neck while still hovering over Simon's entrance. When Jace circled his hole and kissed his neck, sucking on it and leaving a hickey, Simon abandoned his reluctance. "Jace, if you don't fucking put your dick inside of me right now, I swear to god, I will-" he didn't finish because Jace slid into him, with a triumphant smile on his face.

Must be love on the brain
That's got me feeling this way (feeling this way)
It beats me black and blue but it fucks me so good
And I can't get enough
Must be love on the brain

He felt Jace shiver against him and Simon noticed with surprise that he adjusted to the blonde's length very quickly. Jace filled him all the way and stopped, not moving. He could see the blonde's muscles clench and Simon squirmed under him a little. Jace moaned and Simon could see with satisfaction that he was having a hard time controlling himself. "Simon-" he said with a strangled voice and the brunette smirked. "Move, Jace." he said, his tone full of lust. Jace didn't let himself be told twice. The pace he set was too mindblowing for Simon, he just couldn't keep up with his thrusts. Jace moved for a few minutes and then, he pulled back. Simon protested loudly and Jace just chuckled. He put his hands around Simon, flipping him over and Simon pushed himself up on his hands and knees. He felt the loss of Jace's dick and he felt his hole throbbing along with his own dick.

"Fuck." he heard Jace mutter and then he was inside him again, the new angle sending stars dancing behind Simon's closed eyelids. Jace leaned over, impossibly deep inside him, and wrapped and arm around Simon's dick. He was a mess, he moaned loud and he was done for. Jace's deep and controlling thrusts unwinded him and he cursed loudly, when he came. He could feel Jace shiver when Simon's hole clenched when he orgasmed and Jace shouted his name, when he came too after a few more thrusts. 

When Simon could see again (did he black out?), he felt Jace's hands on his back. He pulled out very slowly and carefully and Simon couldn't help but smile. He moved to roll onto the bed, onto his back.  Jace fell down next to him and they both caught their breaths. "I think-" Jace said between breaths "-that we should train like this every day." he finished. Simon gave a laugh, feeling the calm wash over him. He looked towards the blonde, saw his chest fall and rise and he couldn't help it. He leaned over and kissed his shoulder, right on the agility rune. Jace turned his head and gave him a soft look. "What?" Simon asked him and Jace just smiled. "Nothing." he said, leaning in to kiss Simon slowly. It was sweet and just as breathtaking as before, but more... emotional, somehow.

"Ah, fuck." Simon said when he went to sit up. Jace gave him a quizzical look, before he raised an eyebrow. "Should I be sorry?" he asked, a little amused. Simon shook his head, trying to give him an annoyed look but failed. "Nope. I think it was evident that I enjoyed it." he said, moving to get his underwear and jeans. "Yes, you're very vocal." Jace offered with a smug look on his face and Simon felt his cheeks flare up. "I like it." Jace said, kissing his cheek and reaching for his own clothes. Simon rolled his eyes. "Oh, I need that shirt." he said, moving to get it but Jace stopped him. "Just take one of mine." he said, nodding towards the closet and Simon gave him a weird look. "Oookay." he said, a little hesitant.

And it keeps cursing my name (cursing my name)
No matter what I do
I'm no good without you
And I can't get enough

"There you are, I said at 6!" Clary scolded them, when they got to the cafeteria. Then she stopped, elbowing Isabelle who was eating her tortilla next to her. "That's not your shirt, Simon." Clary said, when the boys went to sit down. "That's Jace's." Isabelle informed with a knowing smile. Simon accidentally made a face as he sat down and Clary's eyes went wide. "You-" she started but Simon quickly cut her off "One more word, Fray..." he warned and the redhead shut up, but her smile grew wide. Isabelle giggled. "I have to call Magnus and Alec, Alec owes me and Mags 20 bucks." she said. Jace eyed them both and Clary nodded. "Yep, I'm in on it too." she said, a little guilty. "You bet on this!?" Simon asked, looking at the parabatais, but Jace gave a laugh.

"I find it pretty amusing, to be honest. Although I might have to have a word with Mr. Inquisitor. It's rude to betray one's parabatai like that. I thought he'd be on my side." he continued, biting his food. Simon just stared at him. "You...what?" he asked weakly. "Don't worry about it, babe." Jace said, waving his hand. "Babe?" Simon asked again, incredulous, ignoring the 'fake swooning' from Isabelle and Clary. Jace gave him a wary look. "Too soon?" he asked and Simon smiled. He leaned in and kissed his cheek while squeezing his knee playfully. Jace gave him a look and Simon smirked. "Nope, not at all." he replied, and kissed Jace just below his ear, feeling the blonde shiver slightly under his touch.

The mismatched eyes met his and Simon smiled contently - at least he wouldn't have to worry about the gay panics anymore.
