In the woods, there stood a house with a wind symbol engraved on the door. This symbol belonged to the Hidden Leaf village's Hokage, Naruto Uzumaki Namikaze. He was the Jinchuriki of the nine tails, the Kyuubi. The Kyuubi was female and went by Kurama.
Kurama was a fox with red fur, red eyes and teeth that could make a god piss their pants. Her human form was much softer however. In her human form she was a beautiful woman with striking red hair, blue eyes and a face that was beautiful and terrifying at the same time.
Naruto was a man of thirty years with spiky blond hair, blue eyes, a devilishly handsome face and he was the nicest person you could ever hope to meet.
We see them today in the training grounds outside of Naruto's house with Naruto training. What waits in store for him? Let's find out shall we?
-break-
"Naruto, I think that's enough training." Kurama said, walking out of Naruto's house.
"You know just as much as me that I have to train constantly. Even having my clones train doesn't make me stronger, it only gives me knowledge." Naruto said, upset she would stop his training.
"That may be but I'm calling in that favor you owe me." Kurama said, her voice barely remaining calm because of her lust.
"Fine, what do you want?" Naruto asked, regretting ever telling her he owed her one.
"To put it simply, fuck me." Kurama said with a smirk on her face.
"WHAT?! WHY WOULD I EVER DO THAT?!" Naruto yell-asked.
"Because you owe me one." Kurama said, her smirk growing even more.
"But I'm supposed to marry Hinata soon! I can't do this!" Naruto said, calming down.
"You said it yourself 'Thanks Kurama, I owe you one.' Are you going to go back on your word now, Mr Village Hero?" Kurama said, playing to her one strength - manipulation.
"FINE! I know what I said and I always follow through on my promises. Where do you want me to meet you?" Naruto said, wanting this to end.
"Meet me in the forest of death, the northeast corner. There should be an opening there we can use. Remember, fox form only. I won't have you trying to get me in my human form." Kurama said, stating how they were going to do this.
"Fine, be there in two hours. I need to shower and eat before I do anything else." Naruto said.
"I have waited for almost ten years. I can wait two more hours." kurama said, being patient.
"You've been waiting for this since I was twenty?! Why would you do that?!" Naruto asked.
"Because I can and I have. Now, in two hours, you had better be in the northeast corner of the forest of death." Kurama said, a hint of malice in her voice.
"Alright, I get it. Come fuck you or die, fine." Naruto said as he went to get a shower.
-two hours later in the forest of death-
"Where is he? I told him to be here now. He has five seconds bef-"
"I'M HERE!" Naruto yelled.
"You're late." Kurama growled.
"Yeah, I got caught by the village. Someone needed help cleaning and I was the closest one there. I'm here now though." Naruto said sheepishly.
"Whatever, just transform already and let's do this." Kurama said, excitement entering her voice.
"How do you want to do this?" Naruto asked, changing into his fox form.
"Just go with your instincts and fuck me." Kurama said, turning around and presenting herself.
Naruto's instincts were telling him "FUCK HER HARD! FUCK HER LIKE THE BITCH SHE IS! MAKE HER YOUR SLAVE! SHE IS NOTHING MORE THAN A COCK-SLEEVE FOR YOU TO ENJOY! FUCK HER HARD AND FAST!" At least, that was what his fox senses were telling him. His human senses were telling him "Take it easy, enjoy her and make her feel nice. She is a lady after all." He decided to go with his fox instincts.
As he went towards her, he noticed her doing something he never expected - she was using her tails on herself!
"Ooooohhh… Get over here already! I can't - aaaaaahh - take it anymore." Kurama said, her voice full of poorly hidden lust.
"You asked for it!" Naruto said as he shoved into her, going as far as he could. It felt like heaven to both Naruto and Kurama. They both knew that even with their stamina they wouldn't last long.
"NARUTO!"
"KURAMA!"
As they called each other's names, they both went over the edge. They felt each other for the first time and they both loved it.
"Naruto… that was… amazing!" Kurama said, out of breath.
"You can… say that… again!" Naruto said, out of breath as well.
'We have to do that again, soon!" Kurama said.
"I plan to, with you. Kurama, I never thought I could live with Hinata but now I realize that I don't want to. She is sweet and all but now I think I'm going to stay with you." Naruto said.
"Naruto… thank you." Kurama said, tears in her eyes.
"I just don't know how to tell her I can't marry her. She would be crushed and Hiashi would be out for blood for hurting his daughter's feelings. And no, you will not kill or harm him if he tried, I care for him as well." Naruto said, knowing she would do just that.
"Tell her in whatever way you see fit, I do not care. For now though, you and I will come here once a week and do this until we tire of it. And don't worry, we have all the time in the world. You are immortal after all." Kurama said, smiling.
"OK, I think that's fi- WAIT WHAT?! IM IMMORTAL?! HOW IS THAT POSSIBLE?!" Naruto yelled, surprised to find out he was immortal.
"You are my former host and Indra's reincarnation. You would gain a few things from all that after all." Kyuubi said, explaining to the best of her ability.
"Well, at least we can live together forever then. Thank you Kurama, for everything." Naruto said.
"Your welcome my mate. Goodnight." Kurama said as she fell asleep.
"Goodnight, my eternal mate." Naruto said before he to fell asleep.
