It would be an understatement to say that Izuku had adapted to his new life in a wolf pack. Because, even after what was probably a couple weeks, he still wasn't fully comfortable with it. The cave was too open to raise kits in and, although they paid little to no mind to him, there were wild wolves and wolf hybrids everywhere.
The other hybrids always tried to talk to Izuku but the omega would either panic or they would get shooed away by Katsuki. Though he had managed to get a little closer to them - but only a little. He had felt slightly bad for avoiding them at first. He was aware they just wanted to be friendly, but with his instincts telling him to run it was more difficult then you'd imagine.
Despite Katsuki's constant warnings, though, the hybrids seemed determined to meet him. That resulted in small chats quite often when Katsuki wasn't around. And Izuku did appreciate that the chats were always kept just like that. Small.
All the hybrids did whatever they could to make Izuku comfortable. They hadn't been very good at first; not understanding the boundaries and that only Katsuki was allowed to get close to him at first. But they tried their best. It had been made very clear to them (by both scent and Katsuki telling them) who the rabbits kit were, so they never even attempted to do something they shouldn't. Eijiro had made the mistake of doing that at the beginning by getting to close, and Katsuki wasn't happy. Even with the troubles that Izuku being there brought, Katsuki was always there to give him reassuring licks and comfort him when he needed.
The other hybrids had been shocked to say the least when they first saw their aggressive alpha snuggling up to the rabbit and rubbing his scent against him.
Another thing Izuku was thankful for was that hybrid prey had even been crossed off the menu, in the cave at least. He had wanted to show his gratitude to Katsuki in any way he could have, but the alpha had made it very clear that wasn't necessary.
Katsuki had constantly reassured Izuku that his kit would be safe around the pack, but that didn't stop the uneasy feelings the rabbit had towards it. Deep down, he knew that Katsuki was right. The wolves wouldn't harm his offspring (not without a death wish, anyway) - especially if they had the alphas scent on them, but his kind were hardwired to raise kit within a confined, safe space. A nest.
So, when Katsuki had been out hunting with a few of the others, Izuku went straight to work. It was strenuous and exhausting, especially while pregnant, but the drive to keep his kit safe was too overwhelming for him to ignore.
He had spent a while digging, to the point that he could now fit his body inside and had quite a bit of room to move, so he decided it would be enough for him to stop. At this stage of his pregnancy, he knew he had to be more cautious of how far he pushed himself, so he didn't want to risk overdoing it. Well, that and Katsuki constantly forced him to be more careful with himself. Izuku always complied happily with the alphas request as he knew the alpha was right.
Izuku crawled out from his hole and dusted the dirt off himself. He noted that he would probably need to take a bath in the river to get rid of the dirt caught in his long fur.
As he had been in the cave for a while now, no one really thought anything of it when the omega just got up and walked out. They just assumed he was going toilet or to get a drink or something to eat. That was a normal occurrence among the pack members.
The sun was still high in the sky and there was a light breeze that ruffled Izuku's fur. His alphas scent practically drowned the area in a strong musk that warned other predators off. Izuku was happy he now had nothing to worry about when wandering around alone. He didn't have to constantly watch his own back.
It was almost funny how only a little over three months ago he was telling himself that he didn't need a mate yet; that he would go another heat or two before deciding to settle. But now, Izuku couldn't see himself living any other way. He was still slightly skittish around the wolves and wolf hybrids, but he almost couldn't believe he lived a life alone before this. Katsuki was always there for him, and the other hybrids had his back, too. He was accepted by the predators and they thought of him as nothing less then a friend.
Izuku's hind legs were soaked by the slowly flowing water as he crouched down. The water was cold but his body quickly adapted to the temperature as he began to clean himself with the crystal clear liquids. His normally unruly fur was slick to his form and glistening under the beams of sun.
Cold water continued to flow past his body as Izuku dipped himself into the river as best he could. It wasn't too deep, but in sitting position, about half of Izuku's abdomen was submerged. In the deeper parts of the river, where it became a lake, he would probably be able to submerge his whole body - but he didn't need to do that, so this part worked fine.
In the distance, Izuku noticed a figure leaving the valley between the tall mountains and heading towards him. The musky scent of his alpha hit him before the familiar ash blond fur could fully come into view, so he already knew who it was. A small smile tugged at the omegas lips as he crawled out of the river and shook himself dry. He waited patiently as his alpha approached and gives him a few welcoming licks, which he accepted happily. His scent is stronger then usual and Izuku assumes he managed to get himself worked up while hunting.
There was also the lingering scent of a wild prey, but the smell didn't bother Izuku as much as it used to, though, and that both horrified him and made him happy at the same time. Because, on one side, he was growing more okay with the alpha killing his own, but on the other, it reminded him that the alpha only went after wild prey, not hybrids.
Izuku listened keenly to the low crooning in the alphas chest as he continued to lick the omega hungrily. His sharp teeth would often graze Izuku's skin in little nips, which pulled a small yelp from the rabbit; though these yelps were never a sign to stop, only continue.
As the alpha continued to lick off the moisture from Izuku's previous bath, the rabbit began to slowly lean backwards until he was laying on his back with the alpha over him. Izuku could tell what the alpha wanted from the pheromones he was emitting, and he only encouraged it with his own, honey-sweet scent. An omega always submitted to their alpha.
With the release of those pheromones, Katsuki had released another growl and become more desperate for the rabbit beneath him. He had started to lick down his body until reaching Izuku's already throbbing cock and taking it in his mouth. Once his omega had came, he had proceeded to mount and knot him before returning back to the cave with a noticeably more disheveled and exhausted omega at his side.
The other hybrids had said nothing as Izuku crawled into his nest, instantly noticing the weird scent that filled it. One of the other hybrids must have managed to get in, he noted.
Izuku looked around the rather small nest and smiled, happy with his work. He had moved some animal skins that Katsuki had given him in there to make a comfortable bed. It would have enough room for a number of kits and Katsuki, if the alpha wanted to come in. Izuku hoped he did. To have the alphas scent constantly around him and his soon-to-arrive kit would be a great addition to the small home.
The thought lingered in Izuku's mind as he curled up on the fluffy animal skins. The scents that once belonged to the animals had quickly been replaced with Izuku's own, so he had little to no discomfort sleeping atop them.
Izuku opened one eye tiredly as he peeked up at the entrance to his nest as a noise stirred him into a more awake state. As if his wish had come true, Katsuki was half in his nest and looking around curiously. It was pitch-black, even with the ability to see clearly in the dark. But even so, Katsuki could make out the shape of his omega curled up on animal skins and watching him keenly. The rabbits eyes were almost a luminous green in the darkness, glowing like lights in the night.
Katsuki hovered in the entrance for a second before crawling the rest of the way in and manoeuvring around the curled up rabbit. His steps were gentle and precise as to not step on his omega.
Izuku made no sign of disagreement as the alpha laid down behind him, entangling his limbs with Izuku's own. It was strange to see the hotheaded alpha so calm and touchy, but Izuku had no reason to complain. In fact, the omega craved Katsuki's touches and signs of affection. Whether that was because of his pregnancy or the fact that their scents were bonded as one and the closeness only ensured that fact - it didn't really matter. He just wanted Katsuki.
The alphas strong paw gently stroked the large bump of Izuku's abdomen, feeling each crevice of each stretch mark. This action caused a small, satisfied hum to pass Izuku's lips as his eyelids fluttered shut. He listened to the strong, rumbling croon in the alphas chest as he slowly fell into the depths of sleep; enjoying each gentle lick and stroke the alpha had to give. He was too exhausted to even try and stay awake.
Katsuki watched as his omega slowly fell asleep, listening to his rhythmic breathing. He kept their proximity close as he gently scented the sleeping rabbit and allowed his pheromones to embed itself into the small, homely nest.
At first, Katsuki had been shocked to see the rabbit had managed to make a whole nest in what could have only been a few hours; but the fact that it was his rabbit that had done it made his pride increase by tenfolds. That and the fact he knew this was where his pups were going to be born and raised.
It was still a strange thing for the alpha to think. The omega in front of him was probably only days away from giving birth to his first set of pups. The feeling that thought brought along was indescribable but it never failed to put a smile on his face, which was out of character for him.
Although Katsuki had always told his pack that he didn't need an omega, that had changed very quickly. His pack hadn't made any comment on the sudden swap in his personality when the omega was around. He knew that they had noticed it, though. Hell, anyone who had met Katsuki even once would know that he has changed. It wasn't the hardest thing to miss.
"Katsuki." An all too familiar voice called out in a hushed whisper. Katsuki looked up from his sleeping mate and at the black-furred beta named Eijiro. The wolf was half in the nest and it was obvious he was trying not to wake Izuku.
Katsuki growled quietly as he pushed himself away from the rabbit and slowly manoeuvred around him until he was at the exit. Eijiro backed up as the alpha crawled out. His pack wasn't stupid, even if they did act like complete dunces at times, Katsuki knew they wouldn't disturb him like this if it wasn't important. The alpha waited impatiently as he stared at the beta in front of him.
"We went on a search like you asked." The beta started, his voice growing more serious as he continued. Katsuki could see a fluff of pink in the corner of his eye, Mina, who was watching curiously from the pile of wolves she was currently laying in. He ignored her.
"Did you find anything?" Katsuki asked. Eijiro nodded his head, and the alpha wasn't sure whether he should he relieved or worried with the action. It answers some questions but causes so many more to arise at the same time.
"It looked like the humans had set up camp near the end of the river. We assumed that was how they managed to find their way in and out of the forest without getting lost." The beta explained, trying to recall any and all important memories of what they had found. "The camp was empty but they had left some things behind, we took whatever seemed useful." He nodded his head in the direction of a cluster of objects.
"Good." Katsuki grunted. "If you even think that they have come back to the forest, inform me immediately."
"Will do!" Eijrio did his usual bright smile, revealing a row of extra pointy teeth, as he watched the alpha retreat back into the nest.
Once back in the comfort of his omegas warmth, Katsuki sighed. He knew the humans were going to come back, they probably had their eyes set on Izuku right now. Or rather, they had their eyes set on what was inside Izuku. Humans were greedy, they always wanted what wasn't theirs; Kasuki didn't doubt they wouldn't rest until they had a group of wolf and rabbit cross' in their grasp.
