***** Arrival *****
“Don’t you think they’re perfect for each other?” Hanji squealed, squishing her
cheeks together with the palms of her hand. “Just look at them!” The crazed
scientist looked between the two specimens of Neko, one young and small, the
other large and burly. The small neko mewled in his sedated state, one soft
brown ear twitching, his tail curled around his leg. Small hiccups escaped his
lips as he dreamed.
The other neko was broad, with hair black as night and an attitude to match,
his tail also twitching in his sleep. He was fierce and opposed to every neko
brought his way, set on never having a mate. The Alpha was known as Levi, as he
never responded to anything else. Hanji had known this neko since he was a kit,
and known the hardships he had undergone as he grew. No one deserved happiness
more than Levi.
“Don’t you think he’s a little too… oh, I don’t know…” Moblit muttered
mockingly, “small and fragile for our Levi? He would crush the poor little
thing first chance he got.”
“No, I don’t think so,” Hanji responded, sighing at her clipboard. “They want
results, and Erwin and Armin have yet to conceive, so this is our next bet.”
“But Levi’s always been territorial, and I don’t think it would be a good idea
to shove another neko, a tiny Omega neko, right into his den.” Moblit peered
through the glass into the viewing area, a large space set up for the nekos to
live in. The exhibit consisted of an acre or so of land, all enclosed by one of
the many large buildings used by the Military Police for their more unsightly
experiments. The neko’s living space consisted of a waterfall and pond on the
south eastern side, encompassed by a clearing. A forest took up most of the
remaining space, excluding the rocky terrain covering the northern side,
peppered with caves and spaces for the nekos to build their nests. Birds
resided in the trees, and other herbivorous animals inhabited the forest and
lakeside; all meals for the nekos. While the creatures took on multiple human-
like characteristics, the exhibit was meant for them to embrace their more
animalistic side, and as most of the nekos were born in the laboratory, it
wasn’t a difficult task for them.
“Well, come on, you’ve done the check-up, so let’s get them back in Levi’s
den.”
-----------------
Levi awoke to the scent of lime, flour, and maple, a strangest cacophony of
smells he’d ever placed together. His tale immediately slunk low, his ears flat
against his head, a small growl building low in his chest. The Alpha crept
around his den, the second largest in the Rocks, as the nekos called it, intent
on finding the source of the strange scent permeating his home. Levi heard a
soft mewl from the very back of the cave, and stilled, waiting for any signs of
movement from the darkness behind him. It must have been around sunset (the
time when the scientists dimmed the lights in an attempt to recreate the
lighting of a natural sunset) and the light didn’t quite touch the back of his
den. He let out a harsh snarl, warning the intruder to show themselves. And
show themselves it did.
Levi watched as a small brown neko emerged from the darkness in the back of the
cave, his head hung low, ears flush against his skull, his tail swinging
anxiously behind him. The small boy chirped softly, baring his neck in a show
of submission, his eyes wide in fear at the sight of such a large Alpha
blocking his only escape out of the cave.
“Who are you and what are you doing in my cave?” Levi growled, raising his
chest to seem even bigger to the smaller neko, asserting his dominance. The
brunette gave a snarl of his own, seemingly infuriated at his own lack of
presence. He may be an Omega, but he wasn’t going to let any asshole of an
Alpha mount him.
“I’m Eren and I woke up here, you ass,” the neko yipped, hugging the wall of
the cave, slowly edging his way towards the mouth of the den. “So if you’ll be
so kind as to let me go…” he glanced wearily towards the cave opening, “I’d
really appreciate it.” Levi stood unmoving, his gaze piercing, pinned on the
Omega daring to speak rudely to an Alpha.
“You think you can speak to an Alpha like that, brat?” He snarled, taking a
step closer to him. “You need to learn your place, don’t you? First you invite
yourself into my den, and then disrespect me? Were you raised under a rock?”
“As if, old man,” Eren returned, his tail curling around his leg. “Move so I
can leave.” Levi arched a perfect brow to accentuate his disbelief at the
notion.
“You think I’m just going to let you leave? I’ll let you leave when you’re
carrying my kits, brat.” Eren blushed at the notion, mewling in feigned
disgust.
“Yeah right.” The Omega’s ears twitched as he pondered a way to escape. Levi
could practically see the gears turning in his head. “Where’s your mate,
anyway? You’re old as shit.” The Alpha snarled in response, glowering and
shoving his head at the small neko, now inches apart. The Omega drew away,
cowering into the wall as far as he could.
“No mate. No kits. Now it makes sense why you’re here. Damn Hanji probably
wanted me to mate you. I’d rather mate another Alpha than sire your kits.” Levi
huffed in amusement at the thought. Eren took the opportunity to dart to the
black neko’s left, dashing out of the cave as fast as his little legs could
take him.
This was his first mistake. An Alpha could ever resist a chase involving an
Omega.
Eren practically fell down the side of the rocks, a stranger to the habitat he
awoke in. He yipped in pain every time his delicate paws caught the sharp edge
of a stone or crevice, his Omegan side still dejected at the dejection of the
Alphan neko. Even though he couldn’t care less for the other, the refusal of
even being considered a viable mate still hurt.
Levi made it down to the bottom of the rocky terrain before Eren was even
halfway down, cutting off the small neko’s chance at an easy escape. The Omega
halted on the rocks, hissing down at the Alpha before taking in note of his
surroundings for another option. He caught sight of a small cave to his left,
giving one last glare to the Alpha below him before leaping into the cave,
scrambling to find safety within its walls.
This was his second mistake. Entering another Alpha’s den without permission.
As soon as the brown neko glanced at the cave nearest him, Levi knew there
would be hell to pay. The little brat just had to enter that cave out of them
all. The Alpha crept to the mouth of the cave, bearing his neck to show the
owner his intent; not to fight, but to inquire. He caught sight of Eren in the
back, shivering in fear.
The owner of the cave, an Alpha known as Reiner, snarled and bared his teeth at
the intruder at the mouth of his den, growling lowly in his chest at the sight
of Levi.
“What do you want, Levi?” Reiner lowed, keeping his defensive posture up and
ready to keep his mate safe. Levi peered into the cave, seeing Bertholt,
Reiner’s very pregnant Omega mate, curled around Eren protectively, most likely
sensing the distress of the other Omega and taking him as his own. Pregnant
Omegas were known to be particularly defensive of other Omegas, not to mention
young ones. Eren couldn’t have been much older than a kit, not helping Levi’s
case. The black neko knew his battles, and this was not one of them.
“I simply wanted to get this brat back, Reiner,” Levi responded calmly, “I am
no harm to your mate.” Reiner visibly relaxed at the remark, lowering his
posture to one of only slight discomfort. “He doesn’t know his place, sorry for
the interruption on you and Bertholdt. I’ll be taking him home now.”
“Oh no you will not,” Bertholdt interjected, placing himself completely in
front of the brunette neko, his tail curled around the Omega. “He’s afraid and
I don’t trust you. You’ll kill him faster than you’ll do anything else.”
Sensing his mate’s unwavering confidence, Reiner stepped in front of Levi.
“He’ll be staying here for now, Levi.”
“He’s not yours to keep,” The Alpha responded, ears pressed against his skull.
Levi slowly slunk forward, intent on getting the brat back from the bonded
pair. “Eren,” he yipped, glaring at the small neko, “get your ass over here.
We’re going back to my den.”  At the mention of his name, Eren started to paw
his way over to Levi, only to be stopped by Bertholdt.
“He’s not going, Levi,” The taller neko snarled, his tail flicking back and
forth. “If you want to get to him, you’ll have to get through me.” Reiner
snarled in response, extremely against his mate fighting another neko in his
state; especially an Alpha as strong and quick as Levi. “And we both know how
well that would end. Don’t give Hanji another reason to put you down. You’re
treading on light ground as it is.”
“I see,” Levi rumbled, taking smooth steps backwards towards the opening of the
cave. “I guess I’ll have to wait until I can take him easier, without either of
you there. You shouldn’t be protecting him anyway.” Levi accentuated his point
with a harsh glare at Eren. “See if I care. Hanji’ll return him to me sooner or
later.” With that, the black neko vanished from sight, leaving Reiner,
Bertholdt, and a very trembling Eren alone in the den.
Eren let out a soft cry of distress, curling in on himself in fear. Bertholdt
immediately guided the neko to his nest, a large array of furs and pelts, all
collected by Reiner himself. The elder Omega sat comfortably in the nest,
leaning his back against the wall, ushering Eren over to him with a soft nod of
encouragement. The kit padded towards him wearily before leaping into his lap,
being careful of his stomach after a sharp growl from Reiner. Bertholdt wasted
no time in rubbing his cheek against Eren, scenting the young neko to comfort
him. He took to grooming his ears, nipping the fur occasionally to smooth out
any knots in the delicate fur. The brunette Omega mewled in response, purring
in return and kneading his paws against Bertholdt’s slightly swollen chest,
full of milk for his upcoming litter.
“Isn’t he adorable?” Bertholdt murmured, paying special attention to a dirty
spot behind Eren’s fluffy ear.
“He is, Bertie,” Reiner chuckled, padding over to his mate. “May I enter?” He
took a wary glance at his Omega’s nest, knowing from past experiences not to
enter without permission. After a nod from Bertholdt, the Alpha entered the
nest and laid his head on the rest of the available space on his mate’s lap,
which wasn’t much, considering how much Eren was enjoying the affection from
the tall neko. He mewled and leaned into every possible touch he could, purring
loudly.
“Could it be that he’s touch starved? I’ve never seen another neko so into
grooming,” Bertholdt snorted, running a hand through Reiner’s hair, rubbing on
his blonde ears every time his fingers caught on the fur.
“Mmm, maybe,” Reiner responded absent-mindedly, a low croon sounding from his
chest. It was moments like this with his mate that he loved the most. His
thoughts were interrupted by a low growl from Eren’s stomach. “Oh,” he
muttered, sitting up beside Bertholdt. “I wonder when the last time he ate
was.”
“When was the last time you ate, bun?” Bertholdt asked the other Omega,
nuzzling their foreheads together. “Hmm?”
“I haven’t eaten since I woke up here,” Eren mewled, grooming Bertholdt’s
shoulder with his rough tongue. “I don’t know how long it’s been since then,
though…”
“I see.” Bertholdt gave a pointed look at his Alpha, silently ordering him to
get them something from the forest before returning his attention to the small
Omega. “Reiner’s gonna go get us some dinner, how does that sound? Until then,
you can have some milk.” Reiner growled softly as his mate offered his milk to
someone other than himself or their pups. Then again, their pups weren’t even
born yet, so it made sense that the male’s chest was sore from not having a
constant outlet to release the pressure there. He made note to nurse his mate
more often.
“Alright, alright, I’m going,” the Alpha crooned, nipping Eren’s ear softly and
scenting Bertholdt quickly, peppering small kisses along the Omega’s jaw,
lathering the bond mark on his shoulder in saliva before kissing it once more.
“I’ll be back soon, love. I’ll ask Annie to keep watch over the entrance while
I’m gone.”  
Bertholdt gave his mate one more kiss before the Alpha left. He then came back
to Eren, nuzzling his head and grooming him for a couple more minutes before
breaking the silence.
“Would you like some milk, Eren?” The green-eyed Omega nodded shyly, a light
blush tinting his cheeks. He hadn’t had milk since his mother died a few years
prior. “Then come here, don’t be shy. It’s natural for you to want the comfort
of another Omega.” Eren chirped and hovered his paws over Bertholdt’s chest,
hesitating before bringing his lips to the teat and sucking gingerly, kneading
the breast with his paws. The taller neko let out a pant, petting Eren’s head
soothingly as the milk started to flow freely. The Omega purred around the
nipple, occasionally nipping at it to encourage more of the warm liquid out.
Bertholdt purred in response, letting his head rest back against the cave wall
with a sigh, letting his eyes flutter close.
----------------------------------------
Hanji squealed in amazement. Not only had Mr. Grumpy Pants tried to retrieve
Eren, but had also started imprinting on the small neko, which could only lead
to a permanent bond in her mind. And she was going to make it happen.
“Moblit! This is amazing!” Her eyes sparkled, shaking the man back and forth
with her excitement. “Not only has Eren taken Levi as a potential mate, but
he’s also bonded with another Omega! Bertholdt’s letting Eren nurse from him!
He’s always been secluded from the other Omegas, I can’t believe this!” She
rambled on, Moblit rolled his eyes and let her antics continue. She’d tire
herself out eventually.
***** Attack *****
Chapter Summary
     Erwin and Levi have a little brawl.
As soon as Reiner left his den, he took to marking his territory, scenting the
stones around the entrance with pheromones, sure to stop any other Alpha from
entering the den while he was gone. Content, the Alpha lept artfully along the
stones, pausing at Mikasa and Annie’s den.
“Annie? Mikasa?” Reiner bowed low to show his intent, ears and tail still as he
waited for a response.
“What is it, Reiner?” The Alpha picked his head up at the sound of his fellow
Alpha’s voice, Mikasa choosing to break the silence instead of her mate.
Although the two females were both Alphas, Hanji hadn’t been able to break the
bond they formed. They would be able to sire kits eventually, but they had
always been keen on doing things in their own time.
“I wanted you to keep a watch over my den for an hour or two. Bertie and Eren
are hungry, so I’m fetching them dinner.” Mikasa’s brow arched at the mention
of a neko she’d never met before.
“Eren?” Annie interjected, her ears low, wary of an unknown neko brought into
their territory. “I don’t know an Eren, and if he’s an Alpha, he can get his
furry ass out of here.”
“He’s not an Alpha, Annie,” Reiner chuckled, nudging her playfully with his
paw. “He’s the new Omega Hanji brought in for Levi.” Mikasa snarled at Levi’s
name, her tail twitching in irritation. “He’s very young and afraid, so
Bertie’s been nursing him to calm him down. Poor little thing woke up in Levi’s
den. That couldn’t have been pleasant.”
“It’s not really my problem. Levi doesn’t deserve a mate, anyway,” Mikasa
scowled. “They should just put the short bastard down.”
“Now, now, Mikasa,” Annie chided, twining their tails together. “I don’t like
him as much as the next neko, but we’ve gotta help Reiner out. All we have to
do is keep guard over the den entrance. I’m sure we’ll get something in
return.” The blonde she-Alpha glanced back at Reiner.
“Of course, Annie. I was already planning on getting a buck for Bertie and
Eren. I’ll give you whatever’s left.”
“Bertie’s pregnant, Reiner. I’m sure he’s had an increase of appetite. I
wouldn’t be surprised if he ate the whole deer,” Mikasa frowned, her ear
twitching. “Plus with that other neko eating it, there won’t be any left.”
“Eren probably won’t each much from the kill; he’s just barely older than a
kit. He’ll probably refuse to eat anything other than milk for the most part.”
“I see.” Annie sighed and started towards Reiner, snorting when the other Alpha
didn’t move. “Let’s go then. Show the way.”
Eren had just finishing nursing off Bertholdt’s right breast, hiccuping a few
times before hungrily attaching himself to the other. The older Omega chuckled
and pet Eren’s head lovingly, crooning softly to him. The small neko startled
when Reiner reappeared with two other Alphas. The male Alpha had only been gone
for ten minutes, tops.
“Reiner?” Bertholdt voiced, blinking in surprise. He chirped softly to Eren
when the kit let out a whine. “Keep drinking, it’s okay, bun.” Eren nodded
shyly and continued to knead the breast as he suckled. “What’s going on? Did
you get dinner?”
“I just wanted to show Mikasa and Annie why they’ll be guarding the entrance
while I’m gone, love, don’t worry,” Reiner voiced, rumbling lowly in his chest
to soothe his mate. He turned his attention to the two females. “Eren’s the
little one over there. He’s quite hungry, if you couldn’t tell. I’d imagine
Bertie’s almost empty by now.”
“I don’t know how he’s still eating. Little guy’s got an appetite,” Bertholdt
chuckled, patting Eren on the back when he hiccuped around his nipple again.
“He’s adorable,” Annie murmured, padding over to the neko with Mikasa in tow.
“I’m surprised they managed to find such a cute one. So young…” she trailed
off, her eyes soft as she stared at the little kit. “Can I pet him?” The Alpha
glanced at Bertholdt for permission, sensing the protective aura coming from
him.
“I guess. Just be gentle, he’s had quite a scary day.” Annie nodded and reached
out to him, starting when Eren leaned into the touch absently, still focused on
his newly adopted mother’s breast. He purred loudly and swished his tail around
tiredly.
“He’s so small,” Mikasa muttered, staring at the kit. “I can’t believe they
brought him in for Levi. They should’ve brought him to me and Annie.” Annie
hummed in approval.
“Well, I’ll be going then,” Reiner declared, licking his mate’s cheek a few
times before taking his leave. A few minutes passed and the two she- Alphas
were still completely infatuated with the small neko.
“Go on, then, do your job,” Bertholdt huffed, turning his body away from the
two to shield Eren from them. “He’s tired and hungry, so guard the cave like
good Alphas.” The young Omega’s green eyes shone innocently in the dim lighting
of the cave.
“Watch yourself, Bert,” Mikasa growled, her tail thumping against the hard rock
in irritation. “You may be knocked up, but you know how to properly address me
and my mate.” Bertholdt snarled in response, but refused to say anything more
on the matter. He twisted until his back was facing the two Alphas, Eren
securely clutched to his chest. The brunette neko’s mouth let out a gentle suck
every so often as his eyes drooped, no doubt the warm milk making him sleepy.
“Come on, Mika.” Annie sauntered over to the doorway, laying on her side and
leaning her head into her hand, absently inspecting her nails to pass the time.
Mikasa padded over to her mate immediately, deciding to pace the front of the
cave back and forth. She cringed slightly as Reiner’s scent filled her nose.
She figured he wasn’t content enough with the job, even though the smell of his
pheromones was enough to send any Alpha scrambling.
“Hold on.” Mikasa hissed out into the cool air and took a defensive stance next
to Annie, who in turn, made the same stance in the assumption that there was
danger nearby. The two she-Alphas paced the front of the cave, their ears
fanned forwards, searching for any noises nearby. Their eyes were slits as the
“sun” had long since set, bathing the enclosure in darkness, the only lighting
available from “stars” painted along the ceiling.
“Did you hear that?” Annie whispered, her head darting to the left side of the
den, peering into the darkness ahead of her. Her ear twitched as the sound of
pebbles sliding down the Rocks reached her field of hearing. Mikasa risked a
quick glance behind her, making sure Bertholdt and his kit were still safe.
Bertholdt was fighting sleep on his side, his eyes fluttering every so often as
he attempted to stay awake until his mate returned. Eren was out cold, curled
around his ‘mother’s’ breast in his sleep, soft mewls escaping his parted lips
every so often. The she-Alpha could hear soft purring radiating from the pair.
“Show yourself,” Annie snarled, Mikasa’s attention whipping back to the task at
hand. “I know you’re there, Levi. Don’t make this harder than it has to be.”
Levi emerged in a flash, pouncing on Annie and clutching her by her jugular,
not hard enough to be life-threatening, but enough to cause a measurable amount
of pain. Annie cried out, limp against the hold on her throat. Mikasa roared
and hissed, her ears flat against her head, her tail fluffed out and whipping
around her in an angry flurry. Levi had her mate immobilized, and she knew
better than to take on the other Alpha while her mate was in such a state of
danger.
Bertholdt had awoken during the commotion, retreating into the recess of the
cave, Eren safely behind him. The Omega had his ears flush against his skull,
his eyes dilated in fear, a low rumbling in his chest at the threatening
presence in his den. Eren mewled pitifully, soft tears flowing down his cheeks
as he shook.
“Release her,” Mikasa snarled, crouching low, ready to pounce. “Release her and
we can talk this out.” Levi snorted, not moving a muscle, still hovering above
Annie, his teeth digging harshly enough into her skin to draw blood. Mikasa
understood the unspoken message. It was clear enough by the look in his eyes.
You’ll get yours back when I get mine.
“You’re clearly in rut, Levi,” Mikasa reasoned quickly, taking worried glances
at her mate. “You need to alert Hanji so she can put you somewhere to wait it
out. It’s not safe for you to be here without a mate to relieve you.”
Levi glared furiously at her.
“I’m sure they’re already on their way to get you, Levi. You’ve caused the
Omegas enough distress to stink up the entire enclosure. Release her while you
have the choice.” Levi growled lowly in his chest. “Not only will Hanji be here
to take care of this, but Erwin will be here even faster. You know how he gets
when Armin is in pre-heat.”
Mikasa caught a spark of regret flash through the other Alpha’s stormy eyes.
Sure enough, another Alpha appeared in the doorway, the largest of the Alphas
in the domain, the leader of the pack. Behind him was a small blonde Omega, who
dashed into the middle of the danger to comfort the kit shielded behind
Bertholdt. Bertholdt had known Armin long enough to pay him no mind, joining
him in the soft trilling in attempts to comfort Eren. The small blonde neko was
one of the best in the entire domain at calming other Omegas, whether he knew
them or not.
“Levi,” Erwin’s deep baritone voice filled the cave, silencing the nekos, other
than Armin who continued to purr and trill to Eren. “You should know better
than to not take care of this professionally. You know when your ruts arrive
and you know better than to not be in that room until it’s over.” Levi growled,
tightening his grip on Annie’s throat. The she-Alpha let out a quite whine in
response, her face turning red as her air supply was cut off.
“Erwin,” Mikasa pleaded, her tail swishing frantically at the sight of her
mate. “Hurry, he’s choking her.”
“Levi, release her.” Levi ignored him, clenching his eyes as he fought the pack
leader’s Alphan voice. Sweat started to bead at his temple, leaving a salty
trail in its wake. “Levi, that’s an order. Release Annie immediately.” Levi
unhinged his jaws, letting the soft flesh of Annie’s neck slip through his
fangs. The she-Alpha crawled towards her mate, choking back vomit and panting.
Mikasa straddled her weakened body defensively.
“Leave.” Erwin’s voice was unwavering, his voice slightly strained by the onset
of his rut in preparation for his mate. His tail flittered around anxiously.
However, Erwin wasn’t the only one under the influence of rut. An Alpha in rut
skyrocketed instincts, giving them better hearing, vision, and reflexes; thus,
giving Levi enough resistance against the pack leader. Enough, in fact, to give
him enough courage and confidence to challenge the superior Alpha.
Levi lunged at Erwin, hissing and scratching at his face, catching the blonde
in surprise, giving the raven neko the upper hand. He raked his claws down
Erwin’s chest, leaving deep, bloody gashes. Erwin recovered from his shock and
snarled, throwing Levi off of him and into the wall. Hard.
The raven coughed out blood on impact, dropping limply to the floor of the cave
before staggering back into position. He crouched low, circling the other Alpha
taking in his surroundings calculatingly.
Mikasa had moved herself and her mate into the back of the cave, now positioned
in front of the Omegas already stationed there. Annie kept a low profile,
trying to regain full consciousness after Levi’s earlier attack to her jugular.
Mikasa bit the inside of her cheek forcibly, copper flooding her tongue. She
hoped it was hard enough to trigger the emergency alarm the scientists had
implanted inside of all the neko’s mouths. It was for extreme emergencies only,
as most nekos would rather not impale the inside of their mouths for small
conundrums. Hanji would get the message. In fact, she wouldn’t be surprised if
she had broken the small device. This fight was bad, far worse than any
pointless scuttle Jean could ever dream of starting.
Erwin roared at Levi, raking out with his claws, catching the underside of
Levi’s jaw. The two nekos continued to circle each other until Levi struck once
again. He dug his fangs into Erwin’s flank, the latter letting out a snarl and
kicking the raven neko away abruptly, his tail curling protectively around his
side. Levi hissed and feigned a jump at him again, leaping at Erwin’s jugular
after a missed swipe from the blonde.
Levi would have had a chance at beating Erwin, if Erwin weren’t in rut. In
other circumstances, he would have won and become the pack leader. The
circumstances weren’t in his favor, as the two Alphas had equally heightened
senses, leaving Levi in a crippling disadvantage.
Erwin artfully dodged the attack, throwing Levi to the ground and crunching his
jaws onto the raven’s throat, growling lowly at his victory. The other Alpha
snarled weakly, his limbs flailing out pitifully beside him. Erwin glanced away
from his success and caught a glint in his peripheral. He released the smaller
Alpha after hearing a soft blow from a tranquilizer gun, the dart digging
itself into Levi’s flank, knocking him out in an instant. Levi stilled, as did
the other nekos.
“Thank you, Hanji,” Erwin panted, lowering his head in submission. He had done
his part, and wished to return to his mate. The high from his victory had left
him painfully hard, the adrenaline from his superiority flushing straight to
his groin. “He needs to be in a rut room. He had no sense in his eyes
whatsoever.”
“Thank you, Erwin,” Hanji sighed, ushering the other handlers to drag the
unconscious neko onto a cot so they could transport him safely to first, the
medical room, and then the rut room. “I can’t believe it turned out like this.
This is not how it was supposed to happen. His rut’s a week early.”
“I guess it can’t be helped,” A voice from behind them growled, making them
jump slightly. Other than Erwin, of course. He had smelled Reiner for the past
few minutes.
Reiner maneuvered himself and his kill around the ruckus at the front of his
den, holding himself back at all the unwelcome presences in his cave. He
brought the large buck to his mate, dropping it unceremoniously before scenting
Bertholdt aggressively, rumbling to the others in between licks and nuzzles.
“I’d appreciate it if you all left as soon as possible. I don’t like all of
these unknown scents in my den. It’s not good for my mate or my kit.” Mikasa
and Annie took their leave first, softly letting him know they would return
tomorrow for their share of the buck. Armin left somewhat reluctantly, hating
to leave the other neko. Eren mewled to him until the blonde disappeared with
his mate.
“I’m so sorry about this, Reiner, Bertholdt,” Hanji apologized, wringing her
clipboard with her hands. “I hope this won’t affect your pregnancy.”
“I don’t think it will too much, Hanji,” Bertholdt assured her kindly, petting
his belly humbly. “They’re just excited because of how exciting it got for a
few moments there. I’ll be okay.” Hanji nodded grimly before turning her
attention to Reiner.
“I think Eren’s in pre-heat now,” she sighed, “so it’s best I take him as well.
I don’t want something like this happening again.”
“You can’t just take him now, he’s terrified,” Bertholdt objected, nuzzling
Eren closer to him. “He’s too scared to do anything right now.”
“As much as I know you adore Eren and have taken him as your own, he’s not your
kit, Bertholdt,” Hanji placated when the Omega snarled at the notion that his
kit wasn’t his own. It was an attack at his ability to mother. “You’re a great
mother figure, but you’re not his real mother. As his owner, I must take him to
the safest place for him.” Sensing Bertholdt’s unwavering defense, she sighed
again. “I will return in the morning. Make sure you scent enough material for
him to take into the heat room. You as well, Reiner. Also, make him drink as
much milk as possible. He won’t be able to nurse while in heat.”
“He could. I’ll visit him,” Bertholdt insisted, chirping to Eren’s small whine
of confusion. “Omegas help other Omegas in heat. We always have, we always
will.”
“Alright,” Hanji broke, dragging her feet over to the three nekos. “I’ll see
what I can do. You know I love you guys.” She crouched down and petted Reiner’s
head before scratching Bertholdt’s ears just the way she knew he liked. Once he
purred, she gave him a few more scratches before moving to Eren, who cowered
away from her touch.
“It’s okay, bun,” Bertholdt encouraged, “she’s Hanji. She’s kind, and she just
wants to pet you. It feels nice.”
“Like when you pet me, Momma?” Eren chirped, his green eyes widened in
uneasiness.
“Just like it, bun,” Bertholdt purred, licking the kit’s messy locks. Hanji
took this as a sign for her to continue. She ran her fingers along the
underside of his chin, halting when Eren let out a soft giggle.
“It tickles, Momma!” Eren snorted, leaning into the touch. “I like it.”
Hanji smiled.
 
------------------------------------------------------
 
As soon as Erwin and Armin made it to their den at the top of the Rocks, Erwin
made haste in dragging his Omega to his nest by his scruff, throwing him as
softly as he could into the pelts before mounting him immediately, returning
his jaws to the back of Armin’s neck where the bond mark lay.
Erwin entered in one swift movement, thrusting at a fast pace, his knot already
swelling at the base of his cock. With a growl, he shoved it inside of Armin’s
wet pussy, releasing his load inside of his ready mate. Armin mewled and came
on his Alpha’s cock, slumping down in his hold. Erwin gave a few shaky jerks
into Armin before collapsing down on top of him and peppering his neck with
soft love bites in apology for how hard and unprecedented the mating was.
Armin’s purrs lulled him to sleep.

     Keep in mind that Nekos mature really quickly, and I tried to explain
     it kinda but I'm not good at it...
     Also sorry for the delay, I'm terrible at keeping up with deadlines

See the end of the chapter for more notes
"Do you think he'll be alright, Reiner?" Bertholdt worries, pacing back and
forth in his nest. "He's still so young, he must be so scared..." The Omega
trails off, pausing his steps to cast a anxious glance in his mate's direction.
"You don't think they're trying to... mate him with that abomination, do you?
Levi's way too scary and corrupted for that precious kit." He didn't really
think Levi was a mindless beast; his fear speaking for itself. 
 
"It'll be alright, baby," Reiner reassures him, coaxing him to lie back in the
nest once again. The Alpha shifted from his own position, chirping at Bertholdt
to relax. The Omega whined and peered towards the outside of the cave, longing
in his deep brown eyes. He had always wanted kits of his own, and Eren was the
closest thing he'd ever had to one. He was lucky enough to have fallen pregnant
in the first place, let alone have such a strong Alpha as a mate, as no one
before had ever seemed to want such a tall and lanky Omega. 
 
Feeling his mate's apprehension through their bond, Reiner let out soothing
croons and growls to lure Bertholdt back to the nest. His mate instinctually
obeyed, though his gaze never left the mouth of the den. The Omega fiddled with
the sheets for a few moments before whining in frustration and plopping himself
down on Reiner's lap, purring and nuzzling the underside of his jaw in search
of comfort. The blonde happily obliged, rubbing soft circles into his hips. 
 
"I don't know why I'm so attached to him, Reiner," Bertholdt sniffed, pausing
in between kitten licks on his mate's neck and hairline. "I've barely even
known him for a couple days, and I don't know why I'm so emotional all the
time, and I don't know why you would even want me when you could have had
Armin, or Annie, or Marco, even, I don't..." The Omega was sobbing by now, fat
tears rolling down his cheeks, disappearing almost as soon as they left his
eyes; Reiner letting his mate gush out his feelings as he cleaned the tears
with his rough tongue. Once the harsh sobs slowed to the occasional hiccup and
sniff, he laid the sleepy brunette down into the nest, curling him up tightly
in the furs and ensuring he was warm. Content, he scented the mouth of the den
one last time before joining Bertholdt and spooning him, his hand trailing
along the fatty curve of his mate's belly. He crooned as his palm flattened
over the expanse of skin, clutching the Omega close as he, too, drifted off to
sleep. 
 
===============================================================================
 
 
To say Levi was pissed was an understatement. He was locked in a room, his feet
and arms shackled to chains that latched onto the floor, giving him a berth of
about three feet in any direction, which was, in his opinion, not nearly enough
space for him to do jack shit. The Alpha growled under the muzzle that clung to
his jaw, his pupils slits as he stalked the edge of the wall nearest him. His
length was rock hard between his legs, his rut in full effect as of the last
couple of hours. It was painful, and those bastards gave him no chance of
relieving it. Levi's head whipped around to the door as it swung open, the
heavy steel banging against the wall beside it. 
 
"Oh Levi~" Hanji sung, skipping over to the Alpha. He hissed and pressed his
ears against his skull, sitting low upon the ground, prepared to strike. She
rolled her eyes and beckoned for him to come over to her. "I know you're all
pissy and stuff because of your rut, but listen: we have a surprise for you,
and you'll be allowed to bite whomever and whatever this time. I know how much
you hate the muzzle." He blinked in surprise as she unlocked the muzzle and
removed it from his face, as he had never had a rut without a muzzle on for as
long as he could remember, as he tended to become more aggressive than usual,
and seemed to have a fetish for biting anything and anyone within his vicinity.
As soon as it was removed, her bared his teeth at her and growled lowly, his
patience running thin.
 
"Why am I allowed to bite shit just this time, shitty glasses?" The Alpha
muttered, his tail twitching irritatingly beside him. She chuckled and walked
back towards the doorway, pausing. 
 
"We have a little surprise. You don't have to accept if you don't want to, of
course, but keep in mind that if you don't want it, there are plenty of other
Alphas that wouldn't mind having it..." She paused, bringing a finger to her
chin as though she were thinking as hard as possible. "I do believe Mikasa and
Annie took a liking to it..." With a smile, Hanji disappeared through the door,
closing it behind her. Levi growled and leaned on his side as he waited for his
'present'. 
 
Hours passed, leaving him in the harshest stages of his rut, the peak having
hit him as the fourth hour ticked by. He panted and laid on his side, whining
as his ability was hindered by the chains. He cursed Hanji for removing the
muzzle but not the chains. Precum dripped from his member, his knot swollen and
red from being ignored for so long. The Alpha's ears twitched at the slightest
sound, his instincts going haywire. Levi snarled as the door whipped open once
again, though Hanji wasn't on the other side. Bertholdt and Reiner slowly
stepped in, keeping their distance from the rigid Alpha. Why Hanji was letting
another Alpha into his temporary den was beyond him. 
 
"What the hell? Get out!" Levi roared, fighting against the chains. Oh, how he
urged to rip Reiner's throat out for daring to enter. Sensing Levi's rage,
Reiner showed submission by offering his neck to Levi, intent on appeasing him
as soon as possible. There were more important matters to attend to.
Bertholdt's ears were flat against his head, his tail curled around his leg,
occasionally pressing against his mate's in search for comfort. 
 
"Don't worry, Levi," Reiner soothed, helping Bertholdt over to the nest in the
opposite corner of the room. "We're here to help you." Levi hissed at the
statement, ignorant of the bundle squirming in Bertholdt's arms. Eren made
himself known with a soft mewl, chirping to his mother in confusion as he woke
from his slumber. Levi's ears whipped up at the sound of it, his eyes going
wide as he thrashed against the chains, the savory scent of an Omega in heat
barreling into his nostrils. His eyes were slits, as he snarled and bared his
teeth at the pair. 
 
"Momma? Where am I?" He rubbed his eyes with one fist as he was gently place
into the nest, Bertholdt giving his small ears kitten licks and little nibbles
to clean them up. "Why is it so hot...?" 
 
"Shhh, bun, it's alright," Bertholdt placated, smoothing Eren's tail out. "Levi
here is going to help you, alright? It's gonna be okay, baby, I promise. Reiner
and I will be right outside, understand? If you need anything, just say so and
I'll be here. We're going to go now, baby, I love you." Eren blinked up at
Bertholdt at the confession, his lips curling into a grin. 
 
"I love Momma too!" The older Omega smiled back at him and scented him quickly
before retreating out the door with Reiner. He whined as they disappeared,
confused as to why he was alone and naked in a scentless nest. Why was his
Momma leaving him? And why was Levi chained in the corner? He couldn't be of
any use if he was chained up, and why did he smell so good...? 
 
Levi's shackles unlocked and fell to the ground with a soft clunk as the chains
fell against the padding of the room. Within seconds of being freed, he was
upon the small Omega, his pheromones ordering him to submit to the Alpha. Eren
cried out as he was pinned onto his stomach, his hips slightly raised and his
hands clenching into the sheets in fear. Levi snarled and grappled onto the
back of the brunette's neck, biting harshly as though to dare Eren to move. In
the Alpha's jaws, the smaller neko fell limp, though his tail still whipped
back and forth uneasiness. 
 
"Alpha? What's going on, I don't understand," He cried out as Levi hissed and
pressed his weight down on him harshly, silently commanding him to shut his
mouth. Levi spread the kit's legs until his pelvis was flush against the nest,
keeping his legs pinned apart with his knees. Eren whimpered as something hot
and hard nicked the outside of his pussy, slick dripping down his thighs onto
the blankets from the stimulation. The Alpha pressed himself against the
Omega's back, his cock sliding in between the cheeks of Eren's backside,
prompting him to submit for pleasure. The brunette squirmed in fear underneath
him, mewling in protest as his movements were restricted. 
 
"You're gonna be a good boy for me, won't you, baby?" Levi crooned, nipping at
Eren's ears, encouraging the soft plumes to twitch and react to his
ministrations. "You're gonna take Daddy's knot so well, aren't you?" 
 
"Alpha, what are you-?" The Omega screeched as the blunt tip of Levi's cock
breached his virgin pussy. It paused there, as though to test how well Eren's
cunt would milk him, before inching in agonizingly slowly, prolonging the pain
of the girth filling him without preparation. He instinctively pressed back
against the Alpha's hips, though every movement induced gut-wrenching pain
inside of him. Eren sobbed, fat tears streaming down his cheeks. This was only
his second heat, and his first time every taking something inside of him. For
his first heat, he was mostly unconscious, his body preparing him for
adulthood; his womb growing slightly, his breasts filling out, if only a
little. His vaginal canal also expanded slowly, in functioning order by the
time the heat had ended. Omegas' first heats were to ensure their reproductive
system was functioning. Though they had vaginas when they were born (regardless
of gender), they were small and useless, until they were mature enough to carry
a litter safely (Nekos matured very quickly, able to create families of their
own within two years of birth). 
 
"You're so pretty, aren't you, Eren?" Levi rumbled, his thrusts picking up
pace. "Tell me how pretty you are, Eren." The Omega sobbed and whined as his
heat began to affect his mind, his thoughts going foggy as he was roughly
penetrated. 
 
"Mmm, Alpha, it hurts-" Levi snarled at him for his blatant disobedience,
biting sharply into his shoulder in reprimand. 
 
"Tell me how pretty you are, Eren," He commanded once again. 
 
"I'm...ngh... pretty," the brunette whimpered out through clenched teeth. "It's
too full, I can't-" Levi's thrusts continued to crescendo until the slapping of
skin on skin echoed throughout the room. 
 
"You're taking Daddy's cock so well, baby," Levi praised, now panting into
Eren's neck, occasionally sucking and marking the smooth tan skin there.
"You're so good for Daddy, Eren. Tell Daddy how much you love his cock." 
 
"I love... I love Daddy's cock." 
 
"It makes you feel good, doesn't it? Full? You feel full, don't you, baby?" 
 
"Mhn, so full, Daddy." 
 
"You're my bitch, aren't you Eren? Tell me you're my bitch." 
 
"Daddy! I'm your bitch! Harder, please, it hurts!" Levi hissed in pleasure, his
knot catching on the rim of Eren's pussy, rubbing the sensitive skin raw.
Combined with the sinful squelch of the kit's cunt milking him and Eren's cries
of stimulation, he forced his knot inside the small boy, rutting his hips
deeper and deeper as he bred him. His hips jerked involuntarily as each spurt
of cum filled Eren. The kit had not come yet, as he was pressing back against
Levi's knot in search of an orgasm, though with his hands pinned above his head
he couldn't finish himself off. 
 
Levi brought his hands down to where they were connected; one hand massaging
the tissue engulfing his cock and the other rubbing the kit's clit in circles,
coaxing the boy to come. Eren spasmed as he did, his pussy clamping down on
Levi's knot, earning a groan of pleasure as the tight passage welcomed another
load of cum from him. The brunette's cocklet released seedless ejaculate over
the bottom of his bloated tummy, his entrance squirting cum all over Levi's
hand. The Alpha crooned softly to appease the Omega's fucked out form before
ripping into the delicate skin of the Omega's scent glands, breaking skin and
branding him as his own. Eren came a second time as the bond finalized, his
pussy clenching onto the knot, milking it for every last drop. 
 
"You did so well, baby," Levi murmured, holding the boy close to him as he
drifted off to sleep, a soft mewling snore alerting him that his brat was
already unconscious. 
 
 
===============================================================================
 
 
Hanji watched the pair mate with sparkling eyes. She figured that it was a
question of morals for her to watch Levi completely obliterate a kit's virgin
body, but she couldn't feel anything except pure elation. Her Levi had finally
chosen a mate! Though said mate was a few years older in Neko years and at
least a decade his senior in human years, it didn't matter to her. The
importance was that she had no reason to put him down and had all the more
reason to request more funding, as she was sure they would be expecting a
litter of scowling neko kittens within the next year! 
 
"Moblit," she murmured, "that was absolutely incredible. Incredible." The
scientist turned to her assistant, shaking him with her hands. "Did you see how
well Eren took Levi? He's practically a baby, and he didn't have any
preparation, and he still didn't have any hemorrhaging of tissues anywhere!
Isn't that amazing? He's a virgin and he took a well-endowed Alpha DICK without
ANY help beforehand! Incredible!" 
 
"If I didn't know you better, I'd say you were a pedophile."

Chapter Notes
     Sorry for the long wait, I've been doing a bunch of stuff for my
     Breath of the Wild series, but I hope you like it! Leave me comments
     and let me know what you think! I love constructive criticism!
Hanji watched Eren and Levi copulate a total of sixteen times throughout the
week, roughly two to three times a day as the two Nekos were engulfed in
instinct. Humming to herself, she peered at the television screens in front of
her, her clipboard filled with random notes she dotted down as she "observed"
the pair. A soft mewl earned her attention, glancing at the screen from which
the noise came from. The scientist grinned and sat down into her chair with a
bounce, her clipboard now in hand and a pen twirling in her fingers. 
It looked like Eren had just woken up, his heat now abated as was Levi's rut,
though the two were still stuck together in their private regions. Levi was
spooning the Omega, his knot planted deeply inside Eren's pussy, no doubt
leaking cum every so often despite how used it had been for the past week. She
smiled as Eren mewled, still half asleep, instinctively rubbing his backside
against his Alpha. Levi growled in his slumber, clutching the boy closer to his
chest. The Omega let out a small hiss of protest, no doubt his once-pure body
sore and aching from being plowed into without preparation. 
Suddenly, Levi awoke, his ears pressed against his skull, and flinching away
from Eren as though in shock. He hissed, snarling at the Omega and roughly
pushing him away from himself, effectively ripping the knot out of the poor
brunette. Eren cried out as pain erupted from his lower half, his hole now
gaping and torn from being forced open; he wasn't in heat anymore, and his body
wasn't instinctually opening up for an Alpha. Hanji gasped as a look of remorse
passed over his features, looking almost regretful for hurting the smaller
Neko. Eren sobbed and snarled wetly when Levi tried to approach him again,
swatting at his hands and batting his tail angrily against the ground. 
"Shit," Hanji muttered, tossing her things aside and rushing to the room.
"Moblit, get your ass in here! And tell security to be ready any moment!" She
yelled as she ran through the halls. Moblit, of course heard her, even though
he was in a room almost the complete opposite direction from her, and did as he
was told immediately. 
Hanji thrust the door open, her face frozen in shock as she watched Levi grab
the kit by the scruff and pin him down, his bite so harsh Eren's neck was
bleeding. The Omega's face was turning purple, his airway being cut off as the
Alpha squeezed harder. 
"Levi! What the hell are you doing? You're choking him to death!" The scientist
lept at the pair, pushing Levi off the brunette with all her strength, Eren
screeching once again as Levi's teeth scraped the skin off his neck. "What the
hell is wrong with you?" Levi crouched low against the ground, growling and
glaring at Hanji, blood dripping down his fangs. 
"He's my Omega, I'll do with him what I damn well please," The Alpha snarled,
his nails scratching against the plush flooring, ripping harsh gashes through
them as he kneaded his paws restlessly. "Give him back or I'll be forced to
take him back from you." 
"Like hell you will," Hanji retorted, gathering Eren into her arms. He sobbed
into her shoulder, his tail curling around her forearm in search for comfort. 
"I- I want my Momma." Eren sniffled as he glared at Levi. "I hate you. I never
want to see you again. Ever." Though Levi would never admit it, the words
crushed his heart. His mate didn't want him? He thought he was being good,
breeding him during his heat, grooming him, and trying to keep him still so he
could assess the damage done to the kit's delicate body. He was only shocked
when he first woke up, but realizing what he had done, he intended to take
responsibility for it. He was doing so well before shitty-glasses decided to
barge into the room. 
"I'll take you back to your Momma, sweetheart," Hanji crooned to him, petting
his head softly. "Levi, I know you've never had a mate before, but that was
absolutely ridiculous. He's very young and fragile. You almost killed him." 
"Give me my Omega." Levi's words were absolute, the command sending a chill
down Hanji's body. Slowly, she backed away from the Alpha, one step at a time
towards the door. Security was outside, but if Levi decided to attack her,
she'd be a pile of human scraps before they could get to her. The raven Neko
slunk towards her, low and menacing, a low growl rumbling in his chest. Perhaps
it wasn't the smartest idea to remove the Omega so closely after his heat
ended. It would be harsh on both Nekos and their bond. However, Eren's health
was at stake. 
"I'm not your Omega!" Eren decided to make himself known again. He twisted in
Hanji's arms until he could glare at the Alpha. "You- I don't even understand
what's happened this last week! You kept making me all fuzzy and I didn't even
want it in the first place!" His little nose scrunched up in distate. "I'm- I'm
not your bitch!" Hanji gaped at the brunette, a harsh chuckle choking out of
her throat. 
"Well, you heard it, Levi," the scientist chortled anxiously. "He doesn't want
you, so I'm sorry this didn't work out. I guess we'll find someone else for you
next time your rut comes 'round." Eren gave a nod of approval. 
It all happened in a flash. 
Hanji was suddenly against the wall, Levi's claws digging into her throat as he
held her above the ground. Eren yelped at the sudden flurry of movement and
tumbled out of her arms onto the ground, landing on his side rather harshly.
Hanji's hands immediately went to her throat, grappling onto Levi's hands with
her own, attempting to relieve some of the pressure. Blood started trickling
down her neck and through their intertwined fingertips, staining her lab coat
and splatting onto the ground, some splashing onto Eren's cheeks. 
"You will not take my mate away from me, woman," Levi snarled, his grip
tightening ever so slightly. "You will leave this room, alone, if you want to
live." 
Hanji had never moved so quickly in her entire life. Within seconds, she was
gone. 
"And you," the Alpha growled, closing in on his mate, his face seconds from the
other," need a bath." Eren blinked up at him in surprise. The Alpha had been
snarling and been so, so, so close- he smelled angry and dangerous, he was even
closer now- 
A lick. 
A sandy tongue darted out to lick and groom the frazzled fur on Eren's ears,
occasionally nipping and nuzzling. Eren involuntarily purred, his small paws
kneading in the air as his mate bathed him. He didn't even notice when he was
lifted and put into their nest, instinctively burrowing deeper into the sheets.
The Omega felt so conflicted; he was so young and ignorant. An Alpha he hadn't
even known for a week had bonded and mated him, had knotted him... 
He was so mean. 
But he was so kind to Eren. 
"You're mine now," Levi grumbled possessively, in between licks," so you don't
get to leave me. Ever. Understand?" Eren nodded hesitantly. "Good. You're so
good for me, baby." Levi was smothering the kit now, snuggling against him and
lapping everywhere he could. The Omega's ears, his cheeks, his eyebrows, his
nose. Occasionally his lips.
Eren mewled contentedly, his own little pink tongue peeking out between his
soft lips, as though he, too, wanted to groom his mate. His eyelids fell, and
soon, he fell asleep in the arms of his Alpha once again.  
***** A Mother's Love *****
Chapter Summary
     Babies are born! This one is centered around Reiner and Bertholdt
     during Eren's heat, and there is explicit birth, so be warned! Hope
     you enjoy! Let me know (:
After Bertholdt and Reiner had dropped their kit off, they returned to their
den, albeit very slowly due to Bertholdt's sore ankles and heavy belly. Reiner
had given up and carried his mate back to their den after a few minutes of
impatiently watching the Omega struggle to adapt to the different terrains
within their dome. Reiner knew there was no chance once they reached the
rockier part of the domain. Bertholdt immediately snuggled into his nest,
letting out a coarse huff, exhausted from their short trek. The brunette was
acting restless, twitching and groaning in the nest constantly. 
"Bertie, are you alright?" Reiner asked nervously, settling comfortably next to
his Omega's side. "Is it the kits? Are they kicking a lot?" The Alpha rested
his palm on Bertholdt's taught belly, massaging and kneading the skin gently.
Bertholdt let out a moan. 
"Y-yeah, they're playing soccer or somethin', Reiner, it's killing me," the
Omega whined, his tail wrapping around his mate's wrist. "I- It's worse than
usual. I think they're about ready to come out." Reiner let out a hum, entirely
unsurprised that the kittens were moving around so much. They were nearing
Bertholdt's due date anyway. 
"Just rest if you can, baby," The Alpha crooned. "I'll be here when you need
me, alright? Don't worry too much, when they're ready, they're ready. I'll help
you every step of the way." 
"I- I know, I'm just so scared, and- and Eren! Eren isn't here, what if when he
comes back he thinks we've abandoned him? We're the closest thing he has to
parents, Reiner. It'll kill him to come back and see so many new additions to
the family. He'll be so emotional, too. Poor baby's just going through his
second heat; I don't want Levi anywhere near him! He can help, but I don't want
him anywhere near me or my kittens. He's a bad influence." Reiner listened to
his mate's ranting, rumbling lowly in his chest to show his mate he was
listening and there for him. 
"It's alright, Bertie. Eren will come back fine, he'll be okay, and it won't be
a problem, alright? When he was here he seemed to love the attention from the
other Nekos. I'm sure that new kittens will be a pleasant surprise for him." 
"I hope so," The Omega responded, huffing and gazing at his mate. "Would you go
see if Armin can sleep here tonight? I'm craving some other Omegan attention." 
"Of course, baby." Reiner gave Bertholdt a soft kiss on the corner of his
mouth, leaving the den with the intention of being back in minutes. What he
didn't expect was to find Armin alone in his and Erwin's den. He approached
carefully, glancing warily at his surroundings. 
"Armin?" He caught sight of a shifting lump under the furs of the nest centered
in the cave, small whines coming from the center. "Armin? Are you alright?"
Erwin was not to be seen. 
"Leave me alone." This was very strange behavior for the pack mother. He was
supposed to take care of the other Omegas in the pack, always welcoming them
with open arms. Why was he so upset? 
"I apologize if this is unfortunate timing, but Bertholdt might be having
Braxton-Hicks as of now and he's touch starved. Not for me, but for another
Omega. I've touched him plenty, believe me." As he explained his mate's less
than optimal health, Armin's little ears poked out of the nest, flattening in
distain, knowing there was a pregnant Omega who needed him. He knew he wasn't
being very cooperative. 
"I see. Take me to him." 
 
===============================================================================
 
 
"Oh, Bertholdt," Armin whined, leaping into the nest with the other Omega as
soon as he arrived at the pair's den. "How are you feeling?" The brunette
groaned in response. 
"It- It hurts," Bertholdt whimpered, "It's like they're stabbing my insides." 
"It's alright," Armin purred, helping the pregnant Omega sit up. "Let me scent
you, and see if that helps. They're just excited their Momma is awake, aren't
they?" With a pointed glare at Reiner, he began nuzzling and nipping
Bertholdt's ears. 
"Ah-yes, of course," Reiner rambled, settling behind his mate and rubbing his
taut belly with his palms. "They love their Mommy so much already, don't they,
Bertie? They're just too excited to meet you, they don't want to wait a couple
more weeks. They're just so happy, aren't they, Bertie?" Armin's plan to
distract Bertholdt from the pain seemed to be working so far. The brunette was
sniffling and nodding with each soft description of their kits. 
"Yeah, they're just happy," Bertholdt sobbed, his paws coming up to wipe at his
eyes. Reiner licked his tears away and Armin purred and stroked his thighs
comfortingly. "I can't wait to meet them, Reiner. I can't wait. Even if they're
kicking up a storm inside me." 
The three Nekos continued to chat and groom until Bertholdt was finally able to
get comfortable and fall asleep, draped across his Alpha and the blonde Omega.
Hanji, having just checked on Eren and Levi, had decided to make sure the other
Nekos were alright, and was pleased to find the pile in Reiner's den. She
checked over her files, noting that Bertholdt needed another supplement of
vitamins in the morning, and was now only nine days away from his due date.
Poor thing looked ready to pop. 
With a sigh, she leaned back in her chair, and closed her weary eyes. 
 
===============================================================================
 
 
It happened during the night, days before Eren's heat was supposed to subside. 
It started out with cramping in his abdomen, though not painful enough to rouse
him from sleep, just enough to make he and his mate uncomfortable. Armin had
taken refuge in their nest once again (he and Erwin had been in a fight again,
so it had been routine to camp out at Bertholdt's until the argument had been
settled). Bertholdt broke out into a sweat, whining and calling for his Alpha
subconsciously. Reiner had woken immediately to the sound of his mate's
distress, but made no move to wake him. He was running on instincts as his
mate's labor began, knowing to let him awake naturally. He would need all the
rest he could manage to get before the kits were born. 
"Hush, baby," Reiner cooed, brushing Bertholdt's sweaty bangs out of his face.
"That's a good Omega, being so strong for my kits, aren't you?" Bertholdt was
still in the throes of sleep, tossing and turning, whining and crying out as he
slumbered. Armin had woken up due to the brunette's thrashing, his eyes wide
and his own motherly Omegan instincts taking hold of him.  
Hanji had woken up from the constant whimpering from her security monitors,
squealing when she saw Bertholdt beginning the early stages of birth. Although
she couldn't interfere unless something went dangerously wrong, she could
observe and have Neko specialists on standby. 
"Is there anything you want me to get, Reiner?" Armin asked, his ears twitching
with nervous excitement. "Water, furs, meat? Anything?" 
"I think we're good for now. I've been waiting for this for so long, I've been
prepared since he was six months along." Sure enough, Reiner had spare furs,
water, and dried meats and fruits next to his side. He had moved Bertholdt from
their nest, so as to not get it dirty, and brought him to another side of the
den, where he had dug out a small ditch and filled with water to help ease the
Omega's pain. They hadn't spoken about having a water birth, as it was just the
natural course of how they brought kits into the world. 
"Reiner? Is it happening?" Bertholdt spoke as he blinked sleep out his eyes,
his paws set on his belly. "I don't even remember you putting me in the
water..." 
"It's alright, baby, Armin is here to help if you need him, so just let us know
what you need. You're only dilated about four centimeters, so you have a way to
go. If it gets too unbearable, I'll help stretch you, alright? Let me know."
Bertholdt nodded. 
Armin rubbed Bertholdt's arms, occasionally licking and cleaning his sweaty
ears to soothe him. The blonde purred and let out the most comforting
pheromones he could. Reiner was restless, pacing the mouth of the cave and
insistently checking in on his mate every few minutes. Armin pulled the
brunette's bangs out from his face, using the water to help cool his overheated
body and plaster the hair out of his field of vision. 
"How does it look now, Reiner? I think they're ready!" Bertholdt groaned,
throwing his head back in pain. "Can I push?" Reiner pushed the Omega's legs
apart, peering under the shallow water to check Bertholdt's swollen sex. His
member was erect to keep it out of the way of his hole, the rim red and
dripping with slick to help ease the process. "It hurts, Alpha! It hurts!" 
"I know, baby," Reiner thumbed the outside of the Omega's pussy, soothing the
irritated skin with small strokes. "You're not there yet, baby." 
"They're coming out now! You've gotta finish the stretch, I can't wait any
longer! Please, Alpha!" Bertholdt sobbed, clawing at Reiner's shoulders. 
"Shh, it's alright, Bertie, take a deep breath," the Alpha crooned, pressing up
against the brunette. "I'm going to stretch you, alright? Deep breath, one,
two, three..." On three Reiner pushed his member into the wet heat, groaning as
he was engulfed by Bertholdt's wet cunt. The walls were stretched
uncomfortably, barely hugging his member, signaling that he was almost ready to
start pushing. "Alright baby, when I can take my knot out without pulling on
your rim, you'll be ready to push. Okay? You're almost there, you're so
loose..." Reiner gave a hearty thrust to help entice his knot to form. Armin
pet the brunette's head to keep him calm, chirping out small words of
encouragement. 
"You're doing so good, Bertholdt, being such a good Omega for your Alpha and
kits, aren't you?" Armin cooed, purring and letting his presence soothe the
breathless Omega. "Look at you, taking his knot so well, such a good Omega." 
"Re-Reiner, are you close?" Bertholdt panted, holding his legs apart. "Is your
knot in there? I can't feel anything but pain." 
"Almost, baby," the Alpha moaned, plunging into his mate's pussy and pulling
out to rub himself before reemerging into the heat to coax his knot out faster.
"Here it comes." He gave one last thrust, pushing his knot into Bertholdt and
groaning as he released inside, the knot barely catching on the rim and
slipping out completely a moment later. "You're ready." 
"Thank God!" Bertholdt cried out, clawing at his Alpha's forearms. "It hurts!
It hurts!" 
"You're doing so good, baby, give me a push," Reiner urged. 
"I'm trying!" 
"Good job, I can see a head, you're almost there, keep going. There you go,
baby, one more push and we'll meet our first kitten." Bertholdt screamed as he
gave his last push, tears streaming down his face. The kitten slipped into the
water before being lifted out by its father and handed to its mother. Reiner
bit the umbilical cord off as Bertholdt cooed and nuzzled his first kit,
licking the fluids off of its little face. Its eyes were closed, as it would be
blind for a few days after birth. 
"My baby girl," Bertholdt breathed, scenting the kit's cheek with his own.
"Historia." Armin gathered the kit into his arms as it started whining and
Bertholdt felt more contractions engulf his lower regions. The blonde Omega
finished cleaning off the kit, washing off the rest of the afterbirth and
cuddling up next to it in the pair's main nest. He returned when Bertholdt gave
birth to a baby boy, and again when he had his last kit, another baby girl. 
"You did so good, baby," Reiner praised, gathering his exhausted mate into his
arms after cleaning him off. He carried him to their nest, helping him tuck
into the furs. Armin curled up behind Bertholdt, running a soothing hand along
his hips and sides. "What do you want to name these two?" Bertholdt looked at
the two squirming bundles and let out a hearty purr. 
"This one is Farlan, and the girl will be Sasha." 
"Beautiful names, baby." 
Bertholdt brought Historia and Farlan to his breasts, laying on his side as the
two instinctively wormed their way towards their mother, the smell surrounding
them promising milk. The kits gurgled and mewled around the tits, little purrs
and rumbles coming from their chests as they drank. Bertholdt pet and groomed
Sasha until the other two fell asleep against his chest, cuddling them close to
his head before settling the last kit to his chest, her slurps the loudest of
the three. 
"She's gonna be a big girl, isn't she? What a little piggy, just like her
Daddy," Bertholdt chuckled as Sasha moved onto the other breast. "I don't know
how she's not full yet." 
"She's a Daddy's girl, isn't she?" Reiner snorted, nuzzling his family closer.
As his mate and kittens dropped into slumber, Reiner let out a cloud of
dominating pheromones, clouding the den with protectiveness and hostility,
letting everyone know they were not welcome at this vulnerable time. 
"Thank you for letting me be a part of this, Reiner," Armin whispered, drifting
off to sleep himself behind the brunette. "I hope to have the same someday." 
"Bertholdt needed you. It was no problem at all."  A soft scuttling sounded
outside the cave, making Reiner leap up as his tail puffed out in surprise. He
growled lowly, his eyes trying to adjust to the darkness outside the den. He
scented the air, catching a whiff of pine and heat, and... Eren? 
There was a soft mewl. 
"Mommy?" 
 
***** Surprise? *****
Chapter Summary
     This chapter's basically fluff and Eren realizing what makes an Alpha
     an Alpha. Also I felt like writing some innocent Eren not
     understanding what he was doing smut
Chapter Notes
     (:
Eren awoke again in the arms of his Alpha. He rubbed one sleepy eye with his
paw, vainly attempting to rouse himself from slumber. Blearily blinking the
fuzziness from his eyes, he peered at the figure next to him. Levi was still
fast asleep, his chest rising and falling as he rumbled softly, a low purr
continuing to thrum in his chest even in the throes of unconsciousness. Eren
mewled, shifting his body so he could comfortably snuggle up against the other.
Levi's brows creased, instinctually moving so he was closer to his mate. The
Alpha laid on his back, one arm holding the Omega flush against his side, the
little Neko's paws settled atop his chest. 
"Levi," Eren whispered, poking the Alpha's cheek. His mate gave no response,
simply sighing and clutching the younger male closer to his body. Eren whined,
a small pout making way onto his face. The Omega clumsily climbed onto Levi's
chest, his legs splayed out alongside the Alpha's. Eren rested his chin on his
hands, his face inches away from the raven's, examining ever inch and pore of
the man's handsome face. 
"Woah..." The Omega gazed in awe, taking in the sight of the flawless
complexion that was his mate's face. "How are you so pretty..." he mumbled, one
paw reaching out to curiously prod at the man's lips. Eren lifted Levi's upper
lip, eyelashes fluttering at the pearly white fangs that lined the Alpha's
gums. Those same pearly white fangs that had claimed him, had bit him and
pinned him down, making him squirm... 
Blushing, Eren commanded the dirty thoughts away, releasing Levi's lip
gingerly. The Omega then moved onto Levi's eyes (ignoring the fact that he had,
indeed, given a soft kitten lick to the other's perfect nose). Even in sleep,
the Alpha had a crease in between his eyebrows, making him look angry even as
he slept. Eren prodded the crease until it eventually gave way and smoothed
out. The raven's dark eyelashes were thick and flared out in every direction,
framing Levi's gorgeous silver irises in the best way. His thin brows displayed
most of his emotion, as he refused to show much of anything on his otherwise
stone cold features. Eren's small claws brushed against his mate's eyelashes,
halting when Levi gave a small huff but continued to sleep. The Omega purred as
he watched the lashes flutter and graze against his paw, the hairs tickling his
skin. 
The man had yet to wake, unaware of the insistent irritation his body was
currently undergoing. Eren decided he was done playing with the Alpha's face,
and moved higher, onto Levi's hair. The long black locks were feathery soft,
and Eren's claws could slide through them without catching. Levi's ears were
the same shade of black, trimmed (did Nekos even trim their ear fur? Why would
they in the first place?) short and neat, a thin layer of hair lining the skin
there. The Omega was still purring, his paws unconsciously kneading the flesh
of Levi's chest, his nails nipping the skin there harmlessly. Eren nuzzled
Levi's cheek, scenting him almost possessively. 
Ere pouted when Levi didn't even react. 
Shouldn't an Alpha be over sensitive to their Omega's scent? 
"Leviiiii," Eren drawled, sitting up on the man, his paws on his mate's chest
offering him support as his thighs gripped Levi's hips. "Levi! Wake up!" Eren
smacked his mate's chest stubbornly. "Wake up!" 
Still no response. Well so much for that idea. 
Eren rolled his hips angrily, gasping when he felt something hard prod at his
ass, his tail poofing out in surprise. He then realized that they were still
naked, his heat only having recently subsided. 
"Hmm? What is that?" The Omega twisted to peer behind him, shrieking when he
saw his mate's... rather impressive manhood pressed flush against the curve of
his ass, the knot already starting to form at the bottom. Curious, Eren scooted
down so he was eye level with Levi's raging boner, his ears flat against his
skull and his eyes wide. He flicked his tail anxiously, reaching out to swat at
it and snorting when it flung right back up to its earlier position, hard and
straight up into the air. Eren's tongue darted out from in between his lips,
his inner Omega wanting to please the phallus for some reason. He wrapped his
paws around the base and licked the tip, ears perking up when his Alpha let out
a low grunt. 
Encouraged, Eren continued suckling on the head, hissing when a bitter taste
flooded his taste bude. A clear sticky fluid started to leak from Levi, and
Eren whimpered, afraid that he had somehow damaged it. Why else would it be
leaking? 
Eren was now intent to fix it, and what better place to put it than where his
instincts were telling him? He could fix it. 
The Omega straddled his mate's crotch, bringing his fingers down to press
against his clit, pushing the skin apart and whining when he felt how slick he
already was. His cocklet was flush against the bottom of his belly, his pussy
tingling and leaking even more slick in preparation for what was coming.
Huffing and pushing his hair away from his forehead, Eren started to lower his
hips slowly, hissing as the blunt head of Levi's cock slipped into his cunt. 
"Le-Levi, it's so big," Eren mewled, pausing to catch his breath. He screeched
as Levi suddenly brought his hips up, all nine inches forcing its way into
Eren's insides in one go. The Omega cried out in pain, his walls having been
forced apart so abruptly. Eren's thighs shook from the pain, his pelvis flush
against Levi's. 
"Eren? Shit, shit, what are you doing?" Levi had involuntarily thrust up into
his mate's heat, waking only once he heard the Omega's cry, afraid for the
worst. Once he realized that he had somehow gotten inside of Eren while he was
sleeping, he immediately surged forwards to try and soothe his sobbing Omega. 
"It hurts! It hurts, Alpha," Eren cried, fat tears rolling down his face, his
tail tensed and curled almost painfully around Levi's thigh. 
"Shhh, I know, baby," Levi rumbled, running his hands up and down the boy's
arms. "It'll hurt for a moment, alright? I don't know how we got into this
position in the first place, but I'm going to lie down, and you're going to
stay still, okay? Can you do that for me?" Eren nodded meekly, sniffling and
glancing up at Levi through wet lashes. As promised, the Alpha laid back down,
his hands moving to the Omega's thighs, rubbing soothing circles into the pudgy
flesh, cooing softly. "Good job, baby. Now roll your hips as much as you can,
and the pain will go away." 
"It- It will?" Eren's little brown ears perked slightly at that notion, his
eyes roaming Levi's face for any signs of deceit. Sensing none, he rolled his
hips carefully, glad he couldn't feel any immediate pain. Encouraged, Eren
started moving his hips faster his cocklet dragging against Levi's abdomen,
leaving small trails of precum. 
"There you go, baby," Levi groaned, closing his eyes. "Just like that, Eren,
you're doing so well." 
"I- I am? I'm not doing anything..." 
Oh, the naivety. 
"You're such a good boy, Eren, being such a good Omega for Alpha, aren't you?
Keep rolling your hips, baby." 
"It feels... ah, weird," The Omega whined, his toes scrunching together. He
shifted his hips to the side, mewling when it hit a spot deep inside of him,
sending sparks shooting throughout his entire body. "Ah! Th-there! It feels
weird there, Alpha!" Eren brought his paws up to his torso, relentlessly
continuing to ride his Alpha. 
"It doesn't feel weird, Eren," Levi reprimanded, grabbing Eren's hips tightly,
sure to leave bruises, "we say that feels good. It feels good, doesn't it?" 
"I-I think so, I... ngh, something- something's coming out! Levi!" The Omega
looked panicked, glancing down towards where they were connected. He could
vaguely see the outline of Levi inside of him, his belly bulging out ever so
slightly. Eren screamed as he came, clenching down on Levi as he absolutely
gushed slick and released seedless ejaculate onto the Alpha's chest. Levi
continued to thrust up into him, grunting and drawing blood from the sheer
amount of force he was using to keep Eren planted above him. 
"Eren, I'm almost there," The Alpha groaned, fucking harder and harder until
his knot finally caught. He snarled as he came, pumping his seed into the
Omega, growling appreciatively as he watched Eren come again, his belly
bloating even more from the sheer amount of cum filling him. The Omega
collapsed, his face wet with tears and drool, panting and twitching. 
"Was I good for Alpha?" 
"Yes, Eren, you were so good, so good, baby. Just for me." Eren purred at that,
nuzzling Levi's cheek and demanding attention. "Such a good boy, aren't you?"
Eren hummed in approval, leaning into Levi's touch and kneading his paws
against Levi's chest. 
It wasn't soon after that they were allowed to leave, and to say that Eren was
excited was an understatement. He couldn't wait to see his mother and tell him
all about what a big boy he was! He mated and had an Alpha now, and they were
going to be a big happy family! He hadn't ever really had a family before, so
he was absolutely beaming with pride and accomplishment. Levi knew that there
was no way Bertholdt hadn't given birth by now, but followed Eren nonetheless,
prepared to help cheer up his mate if he felt abandoned by sudden new additions
to Bertholdt and Reiner's den. 
They reached the mouth of the cave approximately thirty minutes after their
coupling, still reeking of sex and mating, two days after Eren's heat had
ended. The Omega scented the air, confusion scrunching his features. It didn't
smell like milk and meat, as his parents usually did, it smelled like...
like...  
Cotton? Cotton and cream? What would cause the den to smell like that? 
He peered into the cave, eyes widening when he caught sight of not two Nekos,
or three, but six. Reiner, Armin, his mother, and three squirming bundles in
the middle of the nest. His nest, the nest he slept in and cuddled with his
mother in. 
"Mommy?"
