Summary
     Levi never wants Eren to grow up.
     "Let's see if I can make you pretty again."
Notes
     I originally gave myself about 8-10 hours to finish this but a load
     of stuff came up and I was left with only 2 hours! Hopefully it's not
     too hideous, I'm sorry!!
     This is a birthday fic for my baby Sausaged
     Squishyyy, happy birthday!! I know you like age gaps, teacher-student
     (even though this doesn't really have any abuse of authority in
     it...) and angst so I tried my best but I'm really not completely
     satisfied with the way I wrote this - so I might try to re-write it
     at some point. Who knows~
     I hope you have an awesome day even though you probably won't wake up
     for another 6 or so hours.
     TW: Pedophilia and slight mental manipulation, and kinda yandere!levi
     This is the first fic I've ever written where I haven't had a basic
     plan for the storyline - I literally just wrote and wrote until I
     felt it was done.
See the end of the work for more notes
Eren is eight years old when he first meets Levi – the stern-faced twenty-seven
year old teacher who lives a few doors down from the Jaeger family. Carla and
Grisha are going out of town for an international Doctor’s convention and it
has clearly fallen to Levi to babysit Eren for the night.
When they leave with a brief “call us if you need anything,” Eren is left
standing on his own on Levi’s doorstep – so nervous that he’s trembling
slightly. Levi beckons him inside.
“Go put your backpack on the kitchen table.” He orders, and Eren thinks to
himself that he’s glad Levi isn’t his teacher at school. Levi’s voice is harsh
like a whip-crack and leaves no room for arguments. Eren would pick Miss Ral
over him anytime. Once his things are on the table, Eren stands next to it –
his shoulders only just reaching the edge of the countertop and Levi towering
over him. Eren notices Levi’s eyes roving over his small frame and feels his
skin prickling in the wake of the gaze.
Levi’s arms are crossed over his chest.
“You are a pretty one, aren’t you?”
It was clear that Eren wasn’t supposed to answer, so he kept his mouth shut –
not quite understanding why his heart was beating so fast. No one had ever
called him pretty before. Levi’s gaze moves lower, over his torso and legs.
“Lots of friends at school?”
Eren shakes his head ‘no.’ Sure, he talked to Marco or Reiner sometimes, but
Armin was his only real friend. Levi seems surprised.
“Is that so? Pretty thing like you…”
Eren somehow finds enough confidence to speak, his voice somewhat unsteady.
“Pretty is a word to call girls. I’m not a girl.”
The corners of Levi’s lips quirk upwards and Eren feels a surge of elation
course through his stomach. He made Levi smile. It seems like a true
accomplishment. Levi lets out a breathy chuckle and Eren’s heart skips a beat.
“No, ‘pretty’ is a word used only for very special people.”
‘Special?’ Eren has never been called ‘special’ before. Eren is the boy who
gets in trouble for fighting with Jean and gets mediocre grades on tests. He
doesn’t have the face of an angel like Christa; he isn’t super smart like Armin
or super nice like Marco. He’s just Eren. He frowns slightly,
“I’m not special.”
Not even his parents pay him much attention at home – he always finds himself
thinking that his Dad wished he was more intelligent like Armin.
Levi steps forward and ruffles Eren’s hair – a gesture that Eren has seen other
people’s Dads do, but never his own.
“Of course you’re special, Eren.” Eren can’t help but let a blissful, relieved
smile spread over his face. “And you have very pretty eyes.” Levi continues.
Eren likes Levi.
The rest of the afternoon, Eren snuggles into Levi’s lap, watching the TV
programmes that his own parents never let him watch. One of Levi’s arms is
draped around his stomach and the other is holding a book. They sit in silence
until Eren curls into Levi’s chest and falls asleep.
Eren feels a pang of sadness when his parents come to collect him the next day.
  
Eren is ten when his parents adopt Mikasa, who quickly turns out to be
everything they ever wanted in a child. Everything Eren wasn’t.
Cool, calm, collected, intelligent, excelling in all areas. The perfect
daughter.
Eren finds himself even more neglected at home, both his father and mother
doting on Mikasa all the time. He couldn’t help but resent Mikasa for coming in
and stealing what little of his parent’s attention he had, and he takes to
wandering around the area or hanging out at Armin’s house.
One day, Armin is sick with the flu and his grandfather tells Eren that he
can’t come over to play today and Eren is left on his own, wondering what to
do.
He walks by Levi’s house on the way home and before he knows it, his legs are
automatically marching up the pathway and his trembling fingers are already
ringing the doorbell.
Levi opens the door a few seconds later and looks surprised to see Eren there.
“Did your parents send you?” He asks, and Eren nods quickly. He can tell that
Levi doesn't quite believe him – after all, his parents would usually call
first, but it doesn’t seem like he much cares.
The rest of the day is spent on Levi’s lap watching cartoons as Levi
absentmindedly strokes his hairless legs, commenting on how nice and soft they
are. It tickles, but Eren finds himself liking the attention. Levi vaguely
mentions that he wishes that Eren would never get older, or grow any hair on
his legs as it would make him less pretty. Levi likes him just the way he is.
Levi is the first adult to ever say anything like that to him. Everyone usually
tells him to hurry up and grow up, or be more like this, or be more like that.
Eren feels warm and safe with Levi, and this becomes a daily occurrence. Eren
would go to Levi’s house after school and help him with dinner, or Levi would
help him with his homework – and then in the evening they would curl up on the
sofa together, Levi petting Eren. Sometimes his hand would make its way up
Eren’s shirt to splay across the soft skin there, and Eren would feel his heart
beat speed up and his face grow hot. He really liked the attention Levi gave to
him.
One day, Carla asks Eren where he goes every day – but she seems relieved when
he says he’s only at Levi’s house. Eren is surprised that his parents even
notice when he’s gone. He wishes he could just live with Levi.
  
Levi starts kissing Eren when he turns twelve. It begins with soft presses of
his lips to the top of Eren’s head while Eren is on his lap watching TV, and
then to small kisses when Eren first arrives or leaves. Eren is old enough to
know what kissing is; his parents do it, older kids at school do it. He’s
twelve, not three – he knows that it’s something you did with someone you love.
He loves Levi, and he wanted him to kiss him more. The warm feeling when Levi
ghosts their lips together before he goes home is enough to keep butterflies
fluttering in his stomach and his cheeks warm and pink all the way back to his
room.
The first time Levi gently licks at Eren’s lips during their couch snuggle-
session, Eren lets out a surprised squeak. Levi takes this as an invitation
into his mouth, and Eren has never felt his head in such a haze. His heart is
hammering in his chest; his mind feels fuzzy and cloudy. Eren grips onto the
front of Levi’s shirt, holding on for purchase as the older man plunders his
small mouth.
Later, when Eren is getting ready to go home, Levi murmurs in a low voice that
makes the hairs on the back of Eren’s neck stand up in excitement.
“You won’t do this with anyone else, will you?”
Eren shakes his head.
“No, Sir.” Of course he wouldn’t. Levi smiles, softly – and Eren knows that
it’s a smile only for him. Just like Eren’s mouth was only for Levi.
“And you won’t tell anyone, will you?”
Eren shakes his head again.
“Of course not, Sir.”
Levi kisses him chastely on the lips and Eren positively beams.
 
Eren finds light, downy hair growing on his legs that summer and he immediately
panics and shaves it off carefully with his mother’s razor. Levi likes stroking
his legs; Levi likes Eren young and hairless. Eren doesn’t want to grow up.
 
Kisses with Levi get deeper and deeper, and last for longer and longer. Eren is
thirteen now, and is acutely aware that the molten feeling that spikes through
him when Levi runs his hands over his body is arousal. He is also aware that
what they’re doing is illegal. But Eren trusts Levi. Levi is older, more
mature, and more intelligent – Levi is a teacher. Levi would never hurt him.
Levi loves him more than his own parents love him – and Eren would do anything
for him.
Levi’s hand cups Eren’s behind and Eren lets out a breathy moan into Levi’s
hot, wet mouth and squirms in his lap. Soon Eren is going to be too big for
this, and he knows that Levi is dreading that day too. Eren never realised how
short Levi was for an adult until he got his growth spurt – and panic bubbles
up in his chest whenever he gets measured and sees that he’s grown another
inch.
Levi won’t like him when he’s big.
Levi breaks the kiss, smirking at Eren’s flushed face and desperate pants.
“Oh, Eren, you make me want to do things to you that you might not be old
enough for.”
Eren is thirteen years old, he knows what sex is, he knows that Levi is rock
hard underneath him, and he knows that he just wants to feel it.
“I’m old enough.” He gasps, his breath mingling in the small space between
them.
Levi arches an eyebrow at him.
“I don’t know whether that makes me happy or not. A part of me doesn’t want to
you be old enough – I want you young, pretty and innocent forever.”
Eren furrows his eyebrows, his heart beating panic in his chest. He was going
to grow up - there was nothing he could do to stop that. And he hates it.
“Okay, then I’m not old enough.” He replies, his voice coming out breathy and
teasing.
Levi lets out a short bark of laughter, leaning forward to rest their foreheads
together.
“Eren, when did you get so cheeky?”
Eren merely smiles as innocently as possible (he knows Levi loves it when he
does that) and carefully presses their bodies together – trying to feel all of
Levi at once. The low groan that leaves Levi’s lips is the most beautiful sound
Eren has ever heard.
Levi holds Eren’s small hips with a firm grip and grinds them into his own
until flames of scorching hot pleasure lick at Eren’s whole being. He knows
he’s flushed and panting, but the way Levi is looking at him like he’s the most
precious thing on the planet has him melting.
“Such filthy noises coming from such a pretty mouth.”
Eren doesn’t ever want this to end.
“You are mine, aren’t you Eren?”
“Yes, yes, oh god, yes"
His whole body is on fire, he's whimpering and writhing and he knows he truly
belongs to Levi when his hips stutter, his muscles convulse and he comes in his
pants with a desperate cry.
 
Eren changes for gym in a bathroom stall, because he knows Levi wouldn’t want
him showing his body to anyone else.
 
He turns fourteen, starts plucking any facial hairs that peek through onto his
chin and shaves his legs, arms and armpits regularly.
Eren starts to notice that Levi gazes with displeasure at the slowly defining
muscles on his chest, and now that Eren has grown a little bit more – they are
directly the same height.
Levi grumbles about it so much that Eren wants to cry. It’s not his fault he’s
growing – it’s a natural human thing. He doesn’t want to grow, he doesn’t want
to disappoint Levi; he especially doesn’t want Levi to stop thinking that he’s
pretty.
That evening, Eren wraps his hands and then his lips around Levi for the first
time, and feels an overwhelming sense of accomplishment when Levi paints the
inside of his mouth, claiming him as his own a million times over.
 
Eren is fifteen, Levi is thirty-four, and Eren has moved up to Levi’s class in
high-school.
Levi had been in France for the whole of the summer, hosting a camping trip for
the senior French class – and Eren had pined for him every day. On the first
day of school, Eren had made sure that his face and body were hairless, that he
was wearing larger clothes to hide his rapidly filling out form and he’d
practiced his innocent, wide-eyed look a hundred times in front of the mirror
before he’d left.
Eren feels his stomach drop when he realises that he’s taller than Levi now,
and he can see Levi’s eyes narrowing behind his glasses.
They don’t say a word to each other as Eren takes his seat, and Eren finds
himself fighting desperately with a throbbing erection throughout the whole
class as he watched Levi command everyone in that strict voice, looking at them
with steely eyes as if they were dirt on the bottom of his shoe. Eren has
barely seen this side of him before; and its hot.
Levi keeps him behind after school ends, making sure there are no other
teachers in the vicinity and sticking a sheet of paper over the small window in
the classroom door so no one can peak in.
The door is locked.
“You grew up.”
It was an accusation, and Eren bows his head, trying to make himself smaller.
 “You’re getting uglier by the year.”
The words cut into him like a knife to the heart and Eren feels burning tears
well up in his eyes. A single drop bubbles over and rolls down his cheek as
Levi regards him coldly.
“I’m sorry…” He whispers.
A cool hand comes up to cup Eren’s cheek – still slightly rounded from
childhood, but his jaw line rapidly becoming more defined. Levi’s thumb swipes
at the tear track as his other hand expertly undoes his belt.
“Let’s see if I can make you pretty again.”
 
Eren's heart soars when Levi finds him beautiful again with cum dripping down
his face.
“Oh, you are so very special, Eren.”

     I am sorry.
     I hope it wasn't too bad *dies*
