Summary
     Kit and Ty had an instant attraction to each other the first time
     they saw each other, that much is undeniable. But can they find a way
     to channel that attraction without hurting each other?
     "“You really think that?” He asked, voice faint. Kit slowly reached
     out with a hand, placing it gently on Ty’s skinny arm. Ty flinched,
     but didn’t move his arm, just stared down incredulously.
     “Don’t be silly,” Kit grinned, biting the inside of his lip."
Notes
     After my last Kitty fanfiction that I posted, I really wanted to
     write one with smut. So here, some smutty shadowhunters for your
     reading pleasure.
Kit wandered the halls of the Institute, his mind jumbled and legs trembling.
He really, really, really needed to use the bathroom, but his stupid pride
wouldn’t let him ask the Shadowhunters for it’s location. So now he was lost in
the Institute, about to piss himself.
“Damn,” He muttered darkly as he turned another corner where the hallway looked
the exact same as the one he had just gone down. When he had gotten here hours
ago, he had been in too much of a tearful rage to pay attention to where he was
going. He was regretting that now.
Kit sped up as he saw something that looked a little like a bathroom. It was at
the end of the hallway, and Kit started jogging, his aching bladder pushing him
onwards-
“Oomph!” Kit found himself lying on his back, the air knocked out of him and
someone on top of him. As his breathing evened out, he rubbed his eyes and
suddenly became aware of who exactly was on top of him. It was the grey-eyed,
black-haired boy who had held a knife to his throat. Somehow, he looked even
better on top of Kit than holding a knife to his throat.
“Sorry!” The boy, who Kit remembered being referred to as Tiberius, apologized.
He swiftly got to his feet, leaving Kit a sprawled out mess on the floor. Kit
could’ve sworn the boy’s cheeks were turning pink as he offered him a hand. Kit
took it gratefully as Tiberius began to ramble. “We realized you were gone, and
the Institute is huge, you could’ve been anywhere-”
“It’s okay,” Kit said, and biting his lip awkwardly, he asked, “Um, where are
the bathrooms?”
“Oh! Um, there are some right here,” Tiberius replied, gesturing to the propped
open door that Kit had been trying to get to. Kit realized that Tiberius had
barely been making eye contact the entire time.
“Thanks,” Kit said, and squirming a little, he began making his way to the
bathroom. “Tiberius, right?” He asked, and just before the door closed he
caught a glimpse of the boy nodding shyly, a barely noticeable smile gracing
his face.
 
As soon as the door thudded shut after Kit, Ty found himself in a horribly
awkward position. Did he leave, or wait for Kit? If he stayed, it would be
awkward when Kit came back out. But if he left, Kit would probably get lost in
the Institute. Ty sighed, knowing what he had to do. He slid down the wall
opposite the bathroom and waited for Kit to emerge. When Ty had first seen Kit,
he had assumed that Kit would be as snooty and deceptive as his father. That
was a mistake. From what Ty had seen, Kit was actually a pretty good person.
Not to mention the fact that Ty had threatened Kit with a knife, although Kit
didn’t seem to mind that much. Ty wished a million times over that he was
better with people, that he knew how to console Kit about his father. He really
didn’t.
After what seemed like ages, Kit came out of the bathroom. Ty’s eyes snapped
open, and he observed Kit from the floor. Kit gave him a half-smile and walked
over, sliding to the floor next to him. He was close, but not too close. Ty
appreciated that. Ty looked at the differences in their legs. His were crossed
tightly at the ankles, whereas Kit’s were spread out more haphazardly, left leg
bent inwards. Ty’s were clad in black leather, his small feet in typical
Shadowhunter boots. Kit was dressed in his jeans, which were now torn up, holes
scattered throughout the denim. He was barefoot, Ty noticed.
“Ty,” He said quietly. Kit frowned.
“What?”
“My name is Tiberius, but everyone calls me Ty,” Ty clarified hastily.
“Tiberius is kind of a mouthful.”
“I like it,” Kit said, glancing over at Ty, who still wouldn’t meet his eyes.
The boy’s curly head was down. He seemed to be examining a cut on one of his
slender fingers. “My real name is Christopher, but nobody calls me that.”
“You wouldn’t want them to, would you?” Ty guessed, his voice surprisingly
tender.
“No, I don’t think so,” Kit conceded. Ty met his eyes for half a second, before
his head snapped down again. It was enough for Kit though, the half second was
all he needed to refresh his memory of the gray of Ty’s eyes. He bit his lip to
keep from smiling. Ty raised his head suddenly.
“They are probably having dinner, would you like to go down?” Ty asked, moving
to a crouch. His hair flopped over his eyes, and Kit had the sudden urge to
push it away.
“I don’t think I’m ready for that yet,” Kit said truthfully.
“That’s okay,” Ty assured him warmly. “Want me to bring you something?”
“Yes, please,” Kit agreed, becoming more aware of his hunger now that he had
finally alleviated his bladder. “Also, could you take me back to the room? I
don’t think I can find it,” Kit laughed, slightly embarrassed.
“Sure,” Ty straightened up, and Kit scrambled to his feet, walking beside Ty
all of the way to his room. They said goodbye there, Ty promising to get him
something good.
Kit lay down on the provided bed, staring at the ceiling. All he could think
about was his father. He felt a gut-wrenching sadness whenever he thought about
him. Most of the time, Johnny had been deceitful and mean, but behind closed
doors Kit got to see a side of his father nobody else ever did. He had the
capability to be kind, but something so bad must’ve happened that he had
forgotten how. Kit just wished that he knew what.
Kit eventually drifted off. His dreams were plagued by Mantis demons and dark
basements, seraph blades and the sight of his father’s torn apart body.
Sometimes, though, Kit would catch a glimpse of a slender boy dressed in all
black, enchanting Kit with his thick eyelashes and cupid’s bow lips.
Kit woke up an hour later to a knocking at his door. He got off his bed
groggily, swinging his door open. His eyes widened as he saw Ty, standing
before him with a tray of food. He had completely forgotten that Ty was coming
by.
Ty almost giggled at the sight of Kit. His blonde hair was completely
disheveled, sticking up in random places in a weirdly charming way. His cheeks
were red and his eyes were a bit clouded. He looked as if he had been sleeping.
“Sorry, did I wake you up?” Ty apologized as Kit let him into the room. Ty
glanced around a bit, before placing the food on the bedside table.
“Well, yes, but don’t apologize,” Kit said, and then yawned. “I’m starving,”
His voice was throaty, and Ty’s stomach flipped. Kit sat cross-legged on the
bed, taking a large bit of the apple. He patted the bed next to him. Ty’s
angular eyebrows rose a fraction of an inch, and he timidly joined Kit on the
bed. Kit practically moaned in appreciation of the sweetness of the apple, and
Ty dipped his head as he felt his cheeks turn red.
“It’s really good,” Kit chuckled after he swallowed.
“I’m glad,” Ty murmured, trying not to stare at the way that Kit’s adams apple
bobbed as he swallowed. Kit took a swig of milk after he had bitten his apple
down to the core, turning to face Ty.
“Thank you,” Kit said, resting his elbow on his knee and putting his chin in
his hand.
“What for?” Ty angled his body towards Kit in curiosity, eyebrows furrowing.
Kit found that look awfully adorable.
“For not pushing me to come out of my room like everyone else,” Kit said. Ty
met his eyes for the second time, dark eyelashes obscuring most of the gray.
“I understand what it’s like to be overwhelmed by your surroundings. Why do you
think I have to wear those stupid headphones all of the time?” Ty said, disgust
filling his voice. Self-hatred was written all over his face. Kit wouldn’t
stand for it. “I’m not normal, you know.”
“Of course you aren’t,” Kit scoffed. Ty inhaled sharply, his face displaying
just how affected he was by Kit’s words. Kit wanted to reach out to touch his
arm, but he couldn’t. He shook his head with a quiet laugh. “That,” Kit
emphasized, “is what makes you so much better than everyone else here. Normal
is boring, Ty.”
Ty inhaled deeply, looking into Kit’s eyes. The blueness of them was almost
overpowering, reminding Ty of a clear summer sky.
“You really think that?” He asked, voice faint. Kit slowly reached out with a
hand, placing it gently on Ty’s skinny arm. Ty flinched, but didn’t move his
arm, just stared down incredulously.
“Don’t be silly,” Kit grinned, biting the inside of his lip. Ty smiled softly,
his pink lips curving upwards and creating a dimple on his left cheek that
drove Kit crazy. Ty’s eyes flashed suddenly and he stood up abruptly.
“I should let you finish eating,” He said, his eyes maddeningly focused on a
point to the right of Kit’s face.
“Ty-” Kit protested, but was cut off but Ty.
“Goodnight.”
The door slammed shut with an air of finality, and Kit fell backwards on his
bed with a groan.
 
Ty shook his head as he walked down the hallway to his room. This could not
seriously be happening. The butterflies that he got, the nervousness, the
blushing? He was getting a crush on Kit. Ty face-planted into his bed with a
massive sigh, grabbing the nearest pillow and stuffing it under his face. Just
one more thing to make him different. When Alec Lightwood and Magnus Bane had
first gotten together, it had been a huge outrage. Ty didn’t know if he could
handle that. Plus, if he wanted to go to the Scholomance, he would be separated
from Kit for a long time… there were so many issues.
Ty flipped onto his back and grabbed a book from his nightstand. It was a
Sherlock Holmes book, one of his favorites. Ty flipped it open and started
reading. He knew the books so well that he could really just pick up anywhere.
He quickly became immersed in the story, reading for at least an hour.
Ty’s eyes had just begun to start itching when he heard a muffled thump from
somewhere in the institute. Ty sat up straight, trying to focus his hearing.
When all he heard was dead silence, he grabbed his stele and retraced an
awareness rune on his forearm. Closing his eyes, he could faintly make out a
voice.
Clutching his stele in his hand, Ty crept out into the hallway, which was pitch
black except for a few nightlights here and there. As he got closer to Kit’s
room, the noise got clearer. It was a whimpering, with scattered cries for
someone named “father”. Ty swallowed nervously, knocking softly on the door.
When it didn’t stop, Ty opened the door. On the floor was Kit, legs tangled in
his sheets. His body was contracting and spasming as his cries got louder.
“Kit!” Ty ran lightly over to Kit, putting a hand on his shoulder. Kit quieted,
but his eyes were still closed.
“Father? Father?” He asked, his eyes slowly opening, and Ty’s heart pounded.
“No, Kit. It’s Ty.”
“Ty? Ty!” Kit blinked quickly, shaking his head. Ty let out a puff of air,
relieved that he was awake.
Ty rose to turn on the bedside table lamp. The light made visible the sweat
that lay on Kit’s skin. Kit, meanwhile, was still on the stone floor, a hand
holding his left wrist. When he realized that Ty was watching, he scrambled to
a crouch, although he winced as he put a little bit of weight on that hand. Ty
rolled his eyes and dropped to his knees in front of Kit, putting his hand on
Kit’s chest. He gave him a little push, causing him to fall back to a sitting
position, back resting against the bed. Kit groaned, although internally he was
dying because Ty was looking right at him.
“Your wrist?” Ty reached his hand out and Kit offered up his wrist. Ty gently
turned it over so that Kit’s veins were facing upwards. Ty noted how pale the
insides of Kit’s arms were. He put his left arm under Kit’s arm, fingers
splayed out. Kit watched, helpless, an addict of Ty’s touch. With his right
hand, he showed Kit the stele resting in his palm. Kit bit his lip, nodding
quickly. He trusted Ty, and besides his his wrist hurt like a motherfuc-
“Oh!” Kit gave a small gasp as Ty began drawing the iratze. It gave a slight
burning sensation, but it somehow wasn’t painful. The feeling was gone as soon
as it had started, and Kit finally took his eyes off of Ty to examine the rune.
It was pitch black against his skin, drawn just above the location of Kit’s
pain. Kit was surprised by the beauty of it. He could tell the amount of time
that had gone into perfecting the iratze that Ty had just drawn. Looking back
up to Ty, he looked peaceful as he gazed down at his work. Kit observed the way
that Ty’s hair curled against his neck. He had the sudden powerful urge to bury
his fingers in it, but pushed it down.
“Good?” Ty asked, releasing Kit’s arm. Kit took hold of Ty’s own pale arm, and
yanked Ty towards him, catching him off-guard. Ty almost fell on top of Kit,
but caught himself on the bed next to Kit’s head. Ty had to close his eyes as
he realized that their faces were close enough for him to see the golden specks
in Kit’s sky blue irises.
“I’m better than good,” Kit murmured. Ty opened his eyes, looking down at Kit’s
t-shirt. There was no denying the fire that had been lit in his stomach at
Kit’s words. Ty slowly moved his eyes up to meet Kit’s. Kit’s eyes were dark in
the shadow Ty cast over him, and for once, Ty felt comfort while he was looking
into someone else's eyes, not scorn or contempt. Kit lifted a finger, putting
it under Ty’s chin and lifting his face to his. Ty, suddenly feeling
overwhelmed, rose to his feet and hurried to Kit’s door. He paused, glancing
over his shoulder.
“I’ll see you tomorrow,” He said quietly, leaving Kit staring after him and
holding Ty’s stele in between his fingers.
 
The next day, the kids had training with Diana. Ty was hidden in a corner with
a book, occasionally looking up to observe his siblings or Kit. At the moment,
Kit was trying his hand with throwing knives, but it was pretty obvious that he
was better with a staff or sword, or even a bow and arrow. The rest of the kids
were taking turns sparring, in a tournament of some sort. Emma and Julian were
nowhere to be found, but Ty had an idea of where they probably were. Mark had
disappeared as well, but Cristina and Diego were supervising Tavvy. Ty watched
Kit hit the wrong target for the fifth time, and finally stood up, brushing
himself off. He knew he probably owed Kit for just walking out the night
before.
Ty walked up behind Kit silently, startling Kit by placing a hand on his
unexpecting one, which was holding the knife. Their bodies were half an inch
apart, clothes brushing. Kit looked backwards at Ty in surprise.
“You need to fix your stance,” Ty said, aiming a kick at Kit’s ankle that made
him move his foot. Ty could just see the target over Kit’s broad shoulder, but
it was enough. Ty put his hands on Kit shoulders, moving them into the correct
position. “Good. Keep your arm steady… and throw.”
The knife thudded into the dead-center of the target, and Ty smiled with
satisfaction.
“How even…” Kit trailed off, his eyebrows raised. Ty blushed under Kit’s
worshipping look.
“Practice,” He responded, picking up a black-handled knife from the cart. He
twirled it once, before settling into the familiar throwing stance, narrowing
his eyes. He hurled it, watching as it flew into the bullseye of the target
next to the one in front of them. Kit just shook his head. “Okay, that’s enough
training for me,” Ty said, turning towards the doors.
“Wait,” Kit said, grabbing Ty’s arm. “Can we please talk?” Ty’s mind short-
circuited as Kit’s fingers pressed into his skin like hot irons. "Besides, I
have this for you," Kit offered Ty his stele, but Ty waved it off.
“Yeah- yes, sure. Keep the stele,” He tore his arm out of Kit’s grip and led
him to a separate, smaller training room. As soon as the door closed behind
him, Kit exploded with words.
“I’m really sorry about last night, if I did something that made you feel
uncomfortable… please Ty, I didn’t mean too,” Kit had to pause to take a
breath. Ty’s eyebrows were arched, and his arms unfolded as he took a step
towards Kit.
“It’s my fault,” Kit sunk into the sweetness of Ty’s voice, like a fly trapped
in honey. “I shouldn’t have just left you like that,” They were now a healthy
two feet apart, Kit almost against the wall. Looking down at the skinny,
vulnerable beauty in front of him, Kit felt a surge of protectiveness.
“Don’t you dare apologize!” Kit cried. “I should’ve been more aware of your
limits-”
“Just shut up,” Ty chuckled, and closing the space between them, he wrapped his
arms around Kit’s neck, pulling him into a hug. Kit was so surprised that he
almost forgot to hug back, but did, nervously wrapping his arms around Ty’s
middle and resting his cheek on Ty’s head. It felt wonderful, Kit cherishing
the feeling of Ty’s head on his shoulder. Plus, he smelled great. Ty pulled
back eventually, giving Kit a shy smile.
“Look… you have to know,” Kit began. “I think I have feelings for you. Or at
least I’m getting them,” Ty’s face got serious. “Can you just let me do
something? I’ll stop if you don’t like it,” Ty nodded hesitantly, not missing
the way Kit’s eyes kept going down to his mouth. “Ok…” Kit put his hands on
Ty’s face, hands so big in comparison to Ty’s face that his thumbs were able to
be on Ty’s cheekbones while the tips of his fingers were in Ty’s hair. Ty’s
skin was incredibly smooth and warm. Ty gazed up at Kit with interest. He
leaned in slowly, maintaining eye contact until their lips touched.  At that
point, Kit’s eyes fell shut, wanting all of his senses to be focused on the
softness and heat of Ty’s lips. Their lips moved together slowly, but it was
calm and sweet, enough for Kit. Eventually, Ty pulled back gasping for air.
“I think I liked that,” He laughed breathlessly. Kit heaved a sigh of relief,
which was quickly cut off by Ty unexpectedly grabbing the front of his training
gear and pulling him in. Their lips collided, heat and passion in the kiss now.
Ty hummed into the kiss, his arms weaving around Kit’s neck. He twirled a lock
of blonde hair around his finger and tugged, causing Kit to moan helplessly
into the kiss. Kit flushed, breaking the kiss for a moment to push Ty up
against the wall. It was Ty’s turn to moan. Kit didn’t really know what he
wanted. He liked this now, the dominance, but he also found having Ty on top of
him to be insanely sexy. Bracing his hand next to Ty’s head, he kissed him
again for a second, before pulling away. Ty was flattened against the wall
trembling a little, eyes closed and breathing deeply.
“Hi,” He spoke quietly, taking Ty’s chin in his thumb and index finger. “Are
you alright?” Ty opened his eyes and furrowed his brow.
“Not really, I’m sorry,” He whispered. Kit’s mind raced, he didn’t want the
moment to end.
“How about this?” Kit slid down the wall till he was sitting, Ty watching him
in confusion. Kit took Ty’s hand and pulled him down to the ground. He put his
hands on Ty’s hips and positioned him so that he was sitting on Kit’s thighs.
Ty grinned, seeing the genius of Kit’s idea. He felt more in control, but Kit
could still have free range of Ty’s body.
“This is much better,” Ty spoke, voice low and electrifying. Kit felt it
surging through his veins, crackling as Ty leaned forward to kiss him. As Ty
distracted Kit with the kiss, he moved Kit’s arms so that he could pin them
against the wall. Ty kept the kiss teasing, darting his tongue along Kit’s lip
before retreating. Kit felt like whining.
Ty pulled back and grinned devilishly as he left Kit to realize the position
that he was in. Ty had Kit’s arms pinned above his head. Kit gasped as Ty
shifted on his lap.
“How’s this?” Ty asked, voice sultry. He could feel Kit’s arousal under him, so
he knew perfectly well how Kit was feeling. Kit opened his mouth to reply but
instead a shaky breath came out, his chest jumping. Ty continued his movements,
getting into a sort of pattern.
“Ty! I...” Kit broke off with a pained expression, but persevered. “I need to
be able to...to feel you,” Ty rolled his hips again expertly, releasing Kit’s
hands. He wasn’t completely cold-hearted. “Oh god,” Kit moaned. His hands
instantly went to Ty’s waist, hands sliding under Ty’s shirt. They ran up Ty’s
muscled back, searching out every curve and dip. Kit’s cold hands caused Ty to
shiver. Kit mumbled a sorry into the kiss and Ty just snorted, attacking Kit’s
arousal with even more force. He slipped a hand down from the wall and unzipped
Kit’s jeans. Kit fell back to the wall, hands resting on Ty’s thighs.
“What do you want?” Ty murmured, moving off Kit so that their brain processes
weren’t being interrupted.
“I just want you. I want this, of course, but I also want to be there for you
in every other way I can be,” Kit replied. He cheeks were still red with
arousal, but his voice was clear and steady and filled Ty with a strange
feeling that he couldn’t describe.
“Me too. I want to get to know you, Kit. But by the angel, you look hot right
now, and I don’t think I can leave without doing something,” Kit’s eyebrows
rose, watching Ty’s every move. “How’s this?” Ty asked, running his hand over
Kit’s length, squeezing and palming. Kit’s breath hitched and he nodded, his
head falling back with a thud.
“That’s… yes,” He moaned, defenseless to Ty’s hand which was working miracles
over him. He tugged at the hem of Ty’s t-shirt. Ty got the hint and pulled it
over his head, messing up his already tangled hair. Kit’s mouth curled into a
smile, hand pushing hair out of Ty’s face, but it quickly transformed into an
“o” as Ty’s hand went underneath his underwear. “Ah, yes, Ty… oh my god,” Kit
mumbled as Ty’s hand worked over him, finger teasing the head before doing long
strokes. Ty had to spit into his own hand a few times, but it was well worth it
for the look of pure amazement on Kit’s face. “Mmm… I’m gonna c-come soon,” Kit
gritted his teeth as he felt a warmth starting to build. in his stomach. His
entire body was throbbing with the need to come, but Ty wasn’t letting him have
it. “Please Ty… I need it so badly, oh please,” He whispered, staring into Ty’s
eyes. Ty couldn’t believe it, but  he  was about to come from the look on Kit’s
face alone.
“What was that?” He purred, a finger lifting Kit’s chin.
“Please let me come, Ty,” Kit cried. Ty almost came at that, but this was about
pleasing Kit, not himself. He worked his hand faster, hitting all the right
spots continually. Kit cried out as the dam broke, all of the waves of pleasure
that he had felt before combined into one huge wave, carrying him away into
ecstasy. Ty shuddered as he came, just from observing Kit. It was an image that
he knew he would never get out of his head as long as he lived. Kit’s orgasm
eventually died away, and he slumped onto his back. Ty rolled off of him, the
post-orgasm exhaustion settling in his bones. He twined his hand into Kit’s.
Kit turned his face to Ty’s.
“Sorry I didn’t get to help you with your-”
“It’s fine,” Ty said tersely, facing turning pink.
“Wait, did you-”
“Shut up,” Ty mumbled, refusing to look at Kit.
“No way!” Kit was giddy. “You came just from watching me come?” Ty found some
strength and rolled on top of Kit, their faces inches apart.
“Don’t make me do this, Rook,” Ty threatened. Kit put his hand on the back of
Ty’s neck and pulled him down into a sedative kiss. Ty blushed happily as they
pulled apart. They got up, putting their clothes back on. Kit seemed a little
sad that Ty’s shirt had to go back on.
“By the way, I think I’m changing my last name to Herondale, like for real,”
Kit said.
“I like it,” Ty said. “Kit Herondale,” He tried the name out on his tongue.
“Hmm. Maybe I’ll have Julian paint you a mural. He’ll be so proud to have his
very own Herondale in the Institute,” Kit laughed, nudging Ty with his
shoulder. Kit smiled, feeling the happiest that he ever had. A new family, Ty
by his side? What else could he possibly want?
