Thank you for clicking on this and taking your time to read it, I hope you enjoy it.

The forest is a dangerous place, but anyone could tell you that.

It's a home to many different animals and hybrids; full of prey and predator alike. They are sheltered by dense canopies of leaves and the gargantuas expanse of the forest alone. No human with a brain dares travel there. It was just an area kept secret and unknown to mankind.

Humans were aware that hybrids existed, some being kept as pets by those with plenty of money to spare. But to see a wild hybrid was something people didn't experience. A 0.01% chance.

Large canopies of leaves that attached to the trees hung high above the land, a thick and green expanse of various leafy shapes. Small beams of sunlight left for a slightly dim, yet still bright, light to pool around the forest floor. It was quiet and peaceful, a calm without the storm; pure tranquility. That was changed when predator became hungry, though.

An unruly mop of green popped up from a whole within the ground as ears danced around and nose twitched in search of danger.

The coast was clear.

With a small huff, Izuku jumped from his rabbit whole. He was now fully exposed to any predator, he kept in mind; but there was no fresh scent, so all seemed okay. He made sure to fully survey the area. A prey could never be to careful.

Again, the coast was clear.

Izuku kept his body low to the ground. His hind legs were crouched down and he continued to sniff the area with each twitch of his button nose.

His legs were that of a large rabbit; covered in silky green fluff that ended around his hips; this left a porcelain, toned waist exposed. His chest was partly visible behind the green tuff that covered it. He had hands similar to a humans, but they were shaped more paw-like and held much more strength. They were also covered with the viridian fur, reaching up to around his elbow. Two perky ears and a fluffy tail finished of the whole rabbit look.

Izuku placed his front paws onto the ground and set off, moving angelically through each twist and turn the forest had to offer.

It was about midday and Izuku had yet to have a good meal, or a meal to satisfy his tastes, at least. Sometimes the small yellow flowers and grass around his nest weren't good enough. They tasted nice, but the grass and other vegetation in the grasslands that connected the mountains and forest together were more suited to his liking.

The thumping sound of Izuku's padded feet mixed in with the beautiful singing of birds as the rabbit continued his short journey. His nose still twitched attentively, his body ready to spring back home in any sight of danger. But still, he sensed none.

The large trees slowly thinned out as they hit the grasslands. It was a calming view every time Izuku looked upon it. It was a sublime mix of lush green fields that were encased by surrounding mountains. And there was a river running down through all three of the terrains, connecting them as one. Izuku loved it.

The rabbits button nose twitched as he slowly stepped out into the open; ears perked as they listened for the slightest of noises.

For a third time, the coast was clear.

He hopped into the field with his body low to the ground. The longish grass tickled his stomach as he frolicked around casually yet on edge.

Once he was certain he was safe, Izuku practically collapsed onto the floor as the sun casted warm rays down onto his body and heated him as he rolled around in the grass, stretching out. To be able to stretch out like this and play after cooping himself up in his rather small nest was very satisfying.

The rabbit debated taking a quick nap before getting up and continuing his day. After all, the predators could hardly see him due to the colour of his fur and the long grass that encased him, so he wasn't in any immediate danger. He should be able to sleep for a little bit without being eaten.

But he couldn't. He had a nest to refurnish and belly to fill - and his omegan side definitely wouldn't allow for an unsuitable or unwelcoming nest.

Rolling onto his stomach and pushing himself up into a sitting position, Izuku began to shove handfuls of long grass and clovers into his mouth. He picked a few small white flowers dotted around and threw those in his mouth, too. The food in the grasslands was so much sweeter than it was near his nest. It was a luxury every time he got to eat it.

The rabbit made sure to eat as much as he could in attempt to fatten himself slightly as he knew he wouldn't be eating as properly soon. His oestrus was due around this time of the year—

Izuku shook his head to rid himself of the thought. He didn't need to be thinking about that right now, he had more important things to do - such as getting himself new bedding for his nest. His current bedding was growing old.

But a nap first couldn't hurt, right? With a full belly, sleep seemed even more tempting.

A small yawn escaped Izuku's mouth as he flopped back onto the ground, basking in the suns warming heat. He shifted himself until he was comfy and allowed his eyes to flutter shut. He slept peacefully in the bright light of midday and, thankfully, with no predators around to pounce in his most vulnerable state.

But once he awoke, he soon came to realise how grave his idea of sleep actually was.

Izuku's leisurely pushed his body up into a seated position as he looked around himself. The sun was lowering into the horizon and the sky was stained in an explosion of reds and oranges. With the fall of the sun, the temperature had also dropped slightly, too. This caused a small shiver to shake Izuku's body.

He had slept for much longer than he had anticipated; and that scared the small rabbit. There could be any number of predators roaming the surrounding area. Maybe waiting for the right time to strike, maybe waiting for him to put on a chase.

And not only that, but there was a very, very fresh scent of a predator nearby. A wolf hybrid, maybe.

Izuku timidly rose to his feet, though he kept his body as close to the ground as he could, and surveyed the area. The tall mountains loomed over behind him, black peaks blocking the warming sunlight. An uneasy atmosphere almost suffocated the rabbit as his heart began to hammer in his chest.

He tried to put the strange warmth in his body aside as he thought of his escape.

But unfortunately, everything that put him at a disadvantage seemed to rush into the forefront of his mind, blocking out any room for idea of strategy or escape. He was prey, and an omega; an omegan prey, who was due to go into heat pretty soon, meaning his judgement was a complete mess.

The odds were definitely against him.

With one last check of the area, Izuku bolted forward on all fours. He had to get back to his nest. The new bedding would have to wait for tomorrow.

Although he could not see any immediate threat, he knew the coast was not clear.

Dark trees loomed over his body, feeling as if they were folding in on him. Suffocating him. Unfortunately, this wasn't his first time running from a predator, but it never got any easier. It was always the same, nerve-racking experience that left Izuku jumpy for days after. But this was the life prey were forced to live.

After what had felt like a long, gruelling chase, Izuku slowed to a halt; chest heaving and face flushed with exhaustion.

He scanned the area. There was nothing in sight. He inhaled. There was a scent.

It was a distinctly intense scent of musk with a slight tinge of sweet undertones. It was an alphan scent, no doubt about it, and they were close, too close.

In a haste panic, Izuku dived behind a tree, pressing his naked back up against the rough bark. His heart hammered in his chest, his eyes blown wide with fear. The alpha was getting closer - probably around 6 meters away minimum.

The scent was alluring in a way, but Izuku brushed this off as it being the normal alpha and omega complex that caused him to be intrigued. They were different species, yes, but he was clearly still a strong, unboned alpha. It was times like this where Izuku cursed his omegan biology.

Izuku covered his neck, where the two most prominent scent glands were located, in attempts to block his scent. It was hard to smell the intensity of his own scent but he could tell it was strong by the feral growl that rumbled out of the alphas throat. He was getting closer.

Another growl left the alpha.

Izuku could only imagine how hungry the wolf and their pack could be. This was a bloodthirsty predator, so they weren't about to go easy on some timid omega; and that was excruciatingly reality of this situation.

While trying to make as little noise as possible, Izuku peered around the left side of the tree. He saw nothing. Izuku slowly moved back into place, desperately trying to steady his breathing. But the fact that he could smell the predators presence but not see them made the panic build tremendously. He couldn't even pinpoint where they were.

Maybe if he just ran for it he would be able to escape. He knew he wasn't faster than the predator, but he could certainly jump. But would the predator follow him? Would he just end up leading them right to his nest? What would they even do if they found Izuku's nest? Dig it out? Wait outside?

While debating his scarce options, another growl brought him back to the reality he was stuck in. Izuku's head jumped to his right as a breath hit his freckled cheek; his eyes instantly locking with piercing vermillion. He didn't get a chance to take in the predators appearance before he jumped backwards and sprinted.

Izuku moved as fast as his viridian-furred legs could take him, leaping forward and going onto all fours in haste.

Katsuki growled again as he chased after the rabbit, mimicking his stance as all four paws crashed against the floor with force. A feral smirk played on his face as he grew more and more determined to catch the rabbit.

The same warmth in Izuku's body from earlier came back as he felt a release of panicked pheromones spill from his pores. He blinked away the sight blurring in his vision and attempted to clear his head and focus on the very serious situation he had got stuck himself in.

But things weren't going to go his way.

The warmth increased and his legs felt weaker, his strides loosing the usual bounce they had. He stumbled. His vision blurred slightly and an ache formed in his abdomen. He stumbled again.

Izuku fell forward as he tripped over his own feet. His body rolled across the floor and he eventually came to a stop on his back, his head spinning and chest heaving with heavy, panicked breaths.

Katsuki pounced, pulling a loud yelp from from the omega that now laid below him. Izuku looked up at him, wide eyed. The alphas eyes stood out dramatically in comparison to the pale pallet of his skin and ash blond of his hair. As his lips pulled back, sharp teeth were revealed, canines and incisors glistening.

A wet, hot tongue dragged over the sensitive skin of Izuku's neck, applying pressure to the slightly swollen scent gland. Another wave of heat crashed over Izuku and left the rabbit squirming uncontrollably as more pheromones spilled out.

Pointed teeth pressed against his neck, hot breath tickling his skin.

The alphas pheromones were suffocating Izuku, coating him in a musky scent that left him completely drunk. A broken moan forced past Izuku's lips and caused the wolf to freeze, thankfully right before he was about to clamp his strong jaw shut and, inevitably, break the rabbits neck. He pulled back quickly and started down at Izuku with a confused expression.

Izuku squirmed more as his chest heaved with pants, noticeably more laboured than what they had been only moments before. Katsuki inhaled and was hit with a sickly sweet scent. It smelt like a variety of sweet fruits dipped in honey.

Their gazes locked for what could have only been a few seconds; but it felt much longer as the lust that clouded those bright, forest-green eyes cleared all confusion for Katsuki. The rabbit was going into heat, and his alphan scent was only encouraging it. Pride built in Katsuki's chest at the realisation.

Testing the waters, Katsuki released a batch of his own pheromones. He was instantly hooked by the strained groan and release of that honey-like, fruit scent he got in return.

Izuku's head lolled to the side as he spread his legs wider for Katsuki. He was trying to put on a show for the alpha, and Katsuki was definitely desperate to see more. He must have been insane, Katsuki pondered, to give his trust and show himself in such a provocative way to a predator.

But was he complaining? Absolutely not.

Katsuki allowed his gaze to wander as he explored the omega with his eyes. Izuku was well-built, with evident muscles covering his form. His body was adorned with golden freckles and his face and shoulders were flushed a rosy pink.

As the first wave of Izuku's oestrus hit, a trail of slick leaked out of the rabbits entrance; and, oh god, did it smell amazing. Katsuki couldn't help the lustful growl that rumbled through his throat as he dragged himself down Izuku's body, nipping and licking as he went.

The sweet scent only grew stronger as Katsuki grew closer to the source, quickly coming to level with the omegas small cock as it wept in need of attention. Katsuki gave it a testing lick, which pulled out a moan much, much louder than the rest had been. This only encouraged Katsuki to continue with a new found vigour.

The wolf began to drag his tongue from the base to the tip. Izuku could only moan and dig his paws into the dirt as his back arched off the ground. The fact that he had been running from this predator not too long ago was long forgotten in his clouded state of pleasure.

As his curiosity increased, Katsuki slowly took the length into his mouth, being cautious of his sharp teeth. His tongue wrapped around Izuku's cock as his head bobbed up and down. Izuku mewled as he released more of the scent made Katsuki want to mount him more with each second.

Katsuki pulled back and ran a blond-furred hand along the inside of Izuku's thigh, watching as more slick dripped from the rabbits entrance. A growl, sounding like a low croon, rumbled in Katsuki's chest as he dragged his tongue along the the ring of muscle, lapping up the sweet slick.

The taste was indescribable, nothing for it to be compared to; but it tasted fucking amazing and that was all that Katsuki needed.

"Ah!" Izuku's head fell back and his padded feet curled and uncurled as he rested his hind legs over the alphas shoulders. Small ropes of white cum squirted out onto Izuku's stomach and his breathing staggered as his body jolted. He was evidently more sensitive than normal in his heat.

Katsuki pulled away again and starred down hungrily at the rabbit. He was covered in his own seed and looking up at the wolf with intense desire.

Desperate for things to continue, Izuku rolled onto his stomach and pushed his rear up to the predator. His short, fluffy tail wagged erratically as he presented himself in a small show for the alpha. Though, katsuki took a second too long to act, and for a needy omega in heat, that simply wouldn't do.

Izuku shook his hips side to side as he peaked back at the blond and whined loudly, pushing his hips up as far as he could. Glistening slick dripped to the forest floor.

Katsuki cursed under his breath and lined himself up with Izuku's entrance. He concealed a groan through clenched teeth as he pushed himself in. Izuku couldn't help the almost pained moan as the large size of Katsuki's cock filled his warmth in a quick thrust. His body was not made for this size, but fuck it felt good.

The rabbit's walls clenched around Katsuki's cock and hungrily pulled him in as Izuku pushed his hips backwards.

Izuku's body wasn't exactly make to house something so big, but he quickly adjusted to the feeling as Katsuki shifted atop him. The wolf placed his hands either side of Izuku on the ground and steadied his body. And once he was in place, he was off.

The thrusts started of slow but speedily gained momentum. And not long later, he was hammering into Izuku with an exceptional force that left Izuku falling apart beneath him. The tuff of fur that covered Izuku's chest was probably filthy from being pushed against the dirty ground, but grooming and cleanliness weren't top priority to Izuku right now.

Hot breath tickled Izuku's back and sent shivers down his spine. A low groaning that sounded comparable to growling could also be heard, which Izuku could easily tell was coming from Katsuki.

Katsuki's body was much bigger in size and he was a lot stronger than Izuku so the rabbit was practically being flattened into the floor as Katsuki rutted against him. It was rough, clearly something Izuku's body wasn't made to handle; but each time Katsuki's cock hit his cervix at that angle, he couldn't care less about his structure. He wanted this exactly as it was.

The growing sensation of Katsuki's knot was becoming more evident as it pushed against Izuku's entrance, threatening to enter, but not. It was a tease. The wolf was close, and Izuku couldn't wait to feel the sensation on the alphas knot entering him as hot cum filled him. They were different species, so they had nothing to worry about.

"Fuck!" Katsuki growled against Izuku's back, and oh god did his voice turn Izuku on. It was low and slightly gravely but to hear it in such a desperate state, caused by none other then Izuku, it was probably the best thing the rabbit had heard in a very long time.

The large knot pressed against Izuku's entrance a final time before entering with the next thrust. And for the first time, Katsuki actually moaned; and that was what pushed Izuku over the edge. The sensation of warm seed spilling out inside of him and the erratic thrusts of Katsuki quickly pushed him to his second orgasm.

Both Izuku and Katsuki panted heavily in ecstasy, the alphas weight seeming to become even heavier and trapping the omega beneath him.

Izuku seemed to recover from his bliss much quicker as the severity of the situation he was in now hit, again. He was trapped beneath a predator, knot still inside him, and he couldn't do anything about it. Izuku knew his legs would to be wobbly to effectively escape the predator, so he couldn't outrun him. Also, by the time Katsuki's knot has deflated, he will be back to his normal self; a hungry, probably quite pissed of predator.

The small prey could hardly control his breathing as his panic surged. He was going to die. He was going to die. He was going to die.

A small, seemingly annoyed grunt escaped from Katsuki as he shifted. Izuku paused, every cell in his body halting in their panicked movement as he inhaled a sharp breath. He could feel hot breath around his neck, a cold nose pressing against his scent gland. Izuku couldn't stop the whimper that broke free, the wolf was going to kill—

The predator was licking him.

With each calming stroke of the predators tongue, strong, relaxing alphan pheromones were released. Izuku didn't know what to think. What the predator was doing was very calming, but he was a predator. Izuku cursed himself as his eyelids grew heavy and his tense muscles relaxed instinctively. Katsuki huffed a quick breath as he smiled down at the successfully calmed omega beneath him.

Katsuki slowly slipped his cock out once his knot had fully deflated and took a few steps back, giving the prey space. This action only confused Izuku, though.

Hesitantly, Izuku looked back at the wolf who was watching him through narrowed eyes. He looked kind of angry, but from what Izuku had seen so far, that was seemingly a normal emotion for the alpha.

"Leave." Katsuki said, keeping his gaze fixated on the anxious rabbit. "Or I'll kill you."

Izuku nodded his head feverishly as he scrambled to his feet, sending a small, shy smile back to the wolf before scampering off. He didn't know why the predator had let him go, but he didn't want to hang around to find out. So he ran as fast as his shaky legs could carry him, still panicked and in a frenzy but much calmer than what he had been.

He was alive; that was all that mattered.
