I decided to go for a hybrid version of this story because I thought it would make things more interesting.

For those who don't know, Kitsune is a fox and Neko is a cat.

Contains: animal humping and yaoi goodness

Summary: In the Villiage Hidden in the Leaves, the Uzumaki Clan and the Uchiha Clan go back many generations. With the Uzumaki Clan being a kitsune hybrid and the Uchiha Clan being a neko hybrid, they're not only allies but friends from way back in the beginning. Though they both have seperate lands as well as seperate people, they always welcome each other with arms open, one always ready to give any support to the other. Hiding away in deep forests and mountains, hybrids are separate from humans in three ways: 1) They can turn into their designated animal form and become human with the exception of their ears and tail, 2) if they want to get pregnant, they can only do so in their hybrid form, and 3) both male and females can get pregnant. The Uchiha and Uzumaki Clan now have new heirs to their land. This is their story.

It started years ago, when they were little kids. Naruto was running through the forest in his full kitsune form just trying to see how fast he could go. Eventually he got tired and hungry, so he found a raspberry bush close-by and started enjoying his little snack. He heard small, delicate footsteps on the other side of the bush so he peeked his head through. His sky blue eyes widened as he gazed upon a delicate neko walking to a pong and kneeling over for a drink. By the looks of it, the neko was about his age. Almost anyone would say that his glistening fur was black, but Naruto could tell by how the sunlight made his fur shine that he clearly had raven colored fur. He took a step forward, accidentally snapping a twig and saw the neko stop his drinking to turn his head towards the sound of the noise. That's when coal dark eyes met his blue ones. They sat there, staring at each other until the neko decided it wasn't worth his time. With a flip of his head, the neko trotted away before gracefully leaping through some bushes, leaving Naruto still standing and staring at the bushes where the neko had disappeared through.

Naruto soon returned to the Leaf Villiage, turning back into his hybrid form while still thinking about the neko. He was greeted by his father, Minato. "Good to see you back Naruto, but you shouldn't be wondering off by yourself." "I wasn't completely alone daddy." "Oh? Who else was with you?" Naruto had a tint of pink on his cheeks as he looked down at his feet, shuffling back and forth. "Well, there was this neko i saw by the pond." Minato knelt down by Naruto's face and smiled. "Well it's no surprise. It was most likely and Uchiha neko you saw. We Uzumakis and Uchihas go back generations. Now that I think about it, this is the first time you've actually seen an Uchiha neko isn't it?" Naruto looked up at his father with a big smile and nodded. "He was so pretty daddy! His fur was the color of the sky at nighttime and his eyes were pretty too! I want to make him my friend! I want to see him again! Can I daddy? Please!" Minato chuckeld at his son's enthusiasm. "Sure, I don't mind. You'll see more Uchiha's soon enough. In fact, my old friend Fugaku is coming over with his family. They have a son about your age coming over as well. Would you like to see them?" Naruto nodded his head vigorusly. He wanted to know more about these nekos if they were as pretty as the one he met by the pond.

Minato and Kushina Uzumaki were preparing for the arrival of their Uchiha friends. Naruto, though, was more eager then his father or mother and decided to take his place standing right at the front of the door and waiting for these nekos to arrive. He was so excited! There came a knock at the door and Minato swooped Naruto in one arm as he opened the door with the other. "Fugaku, Mikoto, it's nice to see you again. It's been a while." Minato shook Fugaku's hand as he welcomed them inside. "I agree, it's been a bit long since we made a visit like this but we both have been busy so it's understandable." Kushina came into the room while drying her hands on her apron to greet the Uchiha's. She gave Mikoto a welcom hug. "Come on in. I see you've brought Sasuke, but where's Itachi?" "Oh, you know how he is. So caught up in work. Sometimes being a perfectionist like him can be so overwhelming, and now it's starting to rub off on Sasuke as well and he's no older then Naruto."

As the adults carried onto a small conversation, Naruto began observing them. They were kind of pretty, especially the woman that was called Mikoto, but they weren't as pretty as the neko he saw by the pond. Naruto was a bit disappointed.

Mikoto smiled at Naruto who was still currently in Minato's arms. "Hello Naruto. I haven't seen you since you were just a little baby. You've grown into a fine young boy so far." Naruto grinned at the flattery. He had grown hadn't he? "This is my son Sasuke. Can you come out and meet Naruto for me honey?" Naruto's gaze sunk down to the figure that had walked out from behind Mikoto's leg. His eyes widened as a familiar coal color came into view. This was the neko he met by the pond. He remembered these eyes and hair, now spiked up like a duck's rear end and ears that were relaxed by the side of his head.

Minato put the stunned Naruto down. "Naruto, why don't you show Sasuke your room and play for a while." Naruto grinned and made no hesitation to grab Sasuke's hand, quickly towing him to his room. After successfully reaching their location, Naruto began staring at Sasuke, who had decided to stand in the middle of the room. "Hi! Remember me? I'm the kitsune from the pond!" "Oh, so you're the stalker." "Hey! I am not! I just happened to see you there is all." "Hn." They stood still for a few minutes, Naruto unsure of what to do. "You know, you're pretty." Sasuke obviously took offense to the comment. "I am a boy, boys are NOT pretty." "Nene, but you are, really. Your fur and eyes are very very pretty." Naruto smiled. "I am a boy!" "So? Boys can't be pretty?" "No, father says that only girls are pretty." "Nene, but your ears and tail look pretty." Naruto proceeded to walk up to the little neko and began rubbing his ears. He had then just noticed that he was a bit taller then the raven haired neko, but not by much. "You also have pretty hair." Naruto began running his hands through Sasuke's hair, occasionally rubbing his fingers on his ears. Sasuke jumped back. "Don't you know anything about personal space!" "Hey Sasuke let's wrestle!" Before Sasuke could reply Naruto quickly tackled him to the ground. Sasuke was angry at first but then as they began rolling around they both started laughing. Minato interrupted their playing by telling Sasuke that his family was getting ready t depart. The Uchihas said their goodbyes as they left the Uzumaki residence as a new friendship began steadily growing.

~10 Years Later~

As time passed, Naruto and Sasuke's friendship got stronger. They spent a lot of time together and would visit each other often, mostly in forest outside of their villiages. But, as is all creatures who grow older, their bodies begin to change and desire as they go into adulthood through two confusing words: heat and puberty. During this stage in life shows a hybrid transforming from a little boy or girl to a grown man or woman. These words are easy for a neko, but not so easy for a kitsune.

"Naruto, now's the time to start looking for a mate. You must choose wisely for once you mate with a person, you are both together for life." "But dad-" "Your father's right Naruto. You're going to go into heat soon and the first time is the hardest for you to control. Usually whenever a kitsune is in heat for the start of their life they want to get with just anyone they see. You have to make sure that when it happens it's with someone you want to be with forever." Naruto slumped. "It's very important that you seek out a mate immediately before you go into heat." Naruto hmmed as he continued getting lectured. He really wished that he was with Sasuke right now rather then sitting here. It was then he just remembered that he was supposed to meet up with Sasuke today in just a few minutes, and that prick was always antsy whenever he was late. "Can I go meet Sasuke first? I'm supposed to spar with him in a few minutes. Then after that I promise to look for a mate, please!" Naruto looked up at his parents with hopeful eyes. They pondered over it a bit before agreeing to let him go. Naruto jumped for joy before hastily running for the door. "And Naruto." "Yes mom?" "Remember that while you're in your hybrid form, you can get your mate pregnant, okay?" "Right, got it mom! Bye!" Naruto rushed out the door and out of the villiage, ready to meet Sasuke.

After he had arrived to the destination, he saw Sasuke waiting for him impatiently. "Idiot, you're late." "Heh, I'll make it up to you by beating you into a pulp!"

It was sundown before they had finally decided to stop the training for the day, both of them covered in sweat. Naruto was getting a weird feeling, but quickly disregarded it since he didn't think it was important.

"Ne, Sasuke, have you gone through heat yet?" Sasuke took a drink from his canteen, water droplets slowly running down from the side of his mouth slowly south until they ran over his bare chest. "Yeah, it's no big deal." "R-really?" Naruto began getting hot all of a sudden, seeing Sasuke wipe off the sweat from his brow. "Mhm. It's easy to control and it's not like I want to hump the first thing I see. But, my father says it's different for kitsunes. I'm not sure what he meant by that." "I-I see." What was happening to him? He was on fire, his body feeling like he was going to burst. Sasuke took a glance at him and started getting worried. "What's wrong Naruto? You're shaking." Naruto couldn't stand anymore. He slowly made his way to the ground on his knees as he bowed his head down from the burning sensation. Is this what it feels like to be in heat? It felt as if something was taking control of him. He flinched as Sasuke put a hand on his shoulder. Oh no.

"Naruto, is everything okay? Are you sick? You feel hot." It dawned on Sasuke. The quaking, the heat off his body, the questions. It all clicked together right about the time Naruto knocked Sasuke down on his back. Sasuke looked up to see nothing but lust in Naruto's eyes. "I'm sorry Sasuke but it burns!" Naruto leaned down to Sasuke's face and began licking him all over at a fast pace. He lowered down to Sasuke's neck and started licking there before he felt hands on his own face pushing him away. "Naruto get ahold of yourself! You don't want to do this!" "Yes I do!" Naruto tried to push his face closer but unfortunately Sasuke's hands were stronger. "You're in heat! Your lust is clouding your judgement!" "No it's not! I'm doing this because I love you Sasuke!" Sasuke stared at Naruto's face, still in his hands. The most of the lust had gone and he saw determination in his eyes. "I-I only feel this way whenever I'm around you! Its always been you Sasuke!" Sasuke just laid their speechless. "So please, just let me have you." Naruto's eyes began getting clouded with lust once again as he grasped Sasuke's wrists and pinned them to the side of his head. He lowered his face to Sasuke's neck and began licking it. Sasuke started struggling a bit. "N-Naruto, stop. Th-this isn't right!" Naruto's pace began to quicken as he lapped his tongue down Sasuke's neck, down his chest until he reached the brim of his shorts. Sasuke jumped at how close he was to his cock. "O-Okay! That's far enough!" "What's the matter Sasuke? I thought you said that going in heat was no big deal? Unless, you're in heat right now as well." Naruto took both of Sasuke's wrists into one hand and Sasuke began to thrash around, his face red with embarrassment. He gasped as Naruto swiftly pulled off his pants and boxers, throwing them far away. Sasuke did seem to be in heat, but if he was it would soon be over. His cock was hard, but Naruto could tell that it was going to go limp soon. He took it into his hand and started pumping it quickly.

Sasuke's thrashing didn't cease when Naruto started pumping his now erect member. He may have been in heat before but he was still a virgin. He had no idea what to do and he didn't want to give into these unusual sensations, it was un-Uchiha like. No matter how much he told Naruto to stop it apparently only egged the kitsune on as he pumped quicker. He arced his back as he climaxed and came all over Naruto's face, who eagerly licked up his white seed. He was quickly flipped onto his stomach. One of his hands was released from Naruto's grip, but the other one was folded back and pinned onto Sasuke's back by the tan hand. His hips were jerked into the air, now with his upper body on the ground while he was on his knees, ass in the air. He gasped as Naruto used his other free hand to wrap around his waist and once again pump his member, but slower this time. Naruto then buried his face into the ass offered to him and quickly started lapping at Sasuke's entrance.

Sasuke didn't know what to do other then grip the green grass below him with his free hand and keep mumbling protests that the kitsune was obviously not listening to. Naruto's tongue was soon quickly removed from the neko's cheeks along with the hand around Sasuke's erection as he used it pull down his pants and free his own erect member. Sasuke knew what was going to happen next but for some reason he couldn't do anything but start slumping down to the ground. Naruto realized this and quickly positioned his hardness at Sasuke's entrance before wrapping his now free hand around his waist again and used it to pull Sasuke's lower half back up, causing him to swifty enter Sasuke.

Sasuke opened his mouth, but nothing came out.

Naruto took no hesitation and began pounding into Sasuke like there was no tomorrow. Sasuke could do nothing as his body began to surrender to the sentations of the pain and pleasure. He could feel Naruto's sacs slap against his own as he thrusted in and out again and again. His hand was still pinned to his back and he could feel himself already on the verge of another release as Naruto continued to hit that spot over and over again without fail. Short moans started being mumbled out of his still opened mouth as he felt saliva begin to trickle down to his chin. Though, even through the pleasure of it all, Sasuke still had to stop this. If Naruto continued then he would release inside of him, and it's not going to be easy to explain the expanding tummy to his father two months later. He tried to tell Naruto to stop but he was still to blinded by his lust to even hear him. It was obvious that he was going to see this through to the end.

Sasuke almost lost it as Naruto wrapped his fingers around Sasuke's cock, quickly pumping it as a signal that he was close to release as well. Sasuke thought fast as he quickly spun around and kicked Naruto on the side of his face, causing him to fly sideways and let go of Sasuke as well as pull out of his hot entrance. Sasuke was on one knee and looked at Naruto, face still full of lust as his hard on was easily seen bobbing in between his legs. "Sorry Naruto but I'm not getting pregnant today." Sasuke changed into his neko form and was about to scurry off until he felt a hand wrap under his stomach as he was picked up. As quickly as he had been grabbed, Naruto easily placed the neko Sasuke back into the previous position he was in before and started rubbing his private regions with his fingers from one hand as the other hand held him down. Sasuke started squirming again. "S-Stop it! Y-you can't fuck me like this-s! It's imp-possible!"

After he deemed he was ready, Naruto once again placed his tip at the little neko's entrance before changing into his kitsune form. His full animal form was clearly bigger then Sasuke's compared to his hybrid form, so he easily towered over Sasuke as his paws were placed each on seperate sides of Sasuke. Sasuke let out a drawled meow as Naruto quickly entered Sasuke's entrance. He held onto Sasuke's stomach with his large paws as he used them to make his body meet with his erection over and over. Sasuke once again began falling into the sensations, giving up any hope in making Naruto stop. At least he won't get pregnant. He felt Naruto's soothing breath at the side of his head as the kitsune slowly licked up the neko's ear over and over. After one final thrust, Naruto came inside Sasuke as Sasuke came just a half second later, both taking in air greedily.

Unfortunately for Sasuke, Naruto was a kitsune in heat for the first time in his life, and one round was definitely not going to be enough. He didn't realize his situation until he had already started feeling Naruto started thrusting inside him again. He started becoming hard soon after the third thrust as he started drawling out meows over and over. Even after they both came the fifth time, Naruto was still going at it. This was going to be the longest night of his life.

"Well, I finally found out who my mate is!" "Yes, but did you really have to do it 23 TIMES!" Naruto grinned as Sasuke gave him a completely angry look. They were currently sitting on the couch in the Uzumaki household with their family the day after Naruto had, as he puts it, 'nailed Sasuke until his dick almost fell off'. Kushina smiled. "Well, at least he found someone he really truly cares about." Fugaku sighed, clearly disappointed that Sasuke had bottomed in the situation, but then again, this is a kitsune, and Minato's son as well. "If it was anyone else but Naruto, I would have never even imagined my little brother bottoming with another hybrid." Naruto grinned as Sasuke gave Itachi a death glare, who just brushed it off as he took a sip of his tea. Mikoto clapped her hands together. "Well, since you two are now together, when can I expect my grandchildren Sasuke?" "Yes, when can I expect my little grown-up Naruto go be expanding the Uzumaki name!" Naruto had a confused look on his face as Sasuke was mortified.

"Grandchildren?"
