Idea: While on a Diplomatic mission to Demon Country, Minato becomes an object of fascination for the King of Demons: Kurama: the Kyuubi no Yoko.

Summary: At eighteen, Namikaze Minato has it made. His girlfriend of six years, Uzumaki Kushina has agreed to marry him, the Hokage has announced that he will be his successor and his students: Rin and Obito have been promoted to Chuunin. But when a routine diplomatic mission runs over the time allotted, Minato suddenly finds himself being pulled it two directions. On one side, he has the love of his life, his fiancée Uzumaki Kushina and his students (one of which is close enough to be his son in all but blood) and on the other, is the frightening king of demons, the Bijuu: Kyuubi no Yoko. What is he supposed to do now?

Disclaimer: I do not own any of them.

Warnings: HET, Mpreg, REGULAR preg, oocness (if you want to think of it that way…) And please, don't review just to say that the warning of mpreg turns you off, I don't care. It actually annoys me. So, no flames please.

Title: The Demon's Mate

(Interruptions)

Minato gently deposited his kits on the couch in the largest mansion of the Namikaze Compound. "Don't move," he told them as he shifted his mate's body in his arms and carried her into their bedroom. He brushed his cheek against hers and watched her for a second before leaving the Master Bedroom.

Minato made his way silently into the basement of the house and turned on the lights. In the center of the room there was a round table with a sphere floating over the center. Inscribed on the floor, every inch of the table, and sphere was a seal. "I never thought that I'd have to use this..." He muttered quietly as he approached it.

Jiraiya would give an arm and a leg for a copy of this one seal if he knew what it did. And this seal wasn't even the most recent seal Minato had created himself. The seal itself was unique, it only responded when Minato activated it with both his voice and chakra.

Minato laid his hand on the sphere and began channeling chakra into it. The sphere and seal glowed dully as the Master of the Compound took a deep breath. "Lock down," he breathed, causing the seal to glow brightly, almost blindingly, before it dulled to a throbbing pulse in time with Minato's heartbeat. "We are safe now," Minato breathed a sigh of relief, pulling his hand off the still-glowing sphere, "No one can get in, and my kits, my mate and I are safe inside..."

Minato turned and left the room, turning the lights off as he did so, leaving the seal glowing and pulsing in the darkness of the room.

His kits were waiting for him at the top of the stairs, "Tou-san! What did you do?" Kakashi asked almost frantically.

"Hush Kit, I have raised a barrier around the Den to protect us." Minato explained, petting Kakashi's hair.

"Sensei... what if we need to go home?" Rin asked.

"This is your home kit." Minato replied to her question, knowing that she had been looking for an apartment after the deaths of her parents.

"But what about Clan Business?" Obito asked.

"Not important." Minato retorted gently, "Now go sit while I make us something to eat."

Seeing nothing else to do, Kakashi, Rin and Obito sat down around a low table to wait for Minato to return.

"What's going on with him?" Rin asked curiously, "Sensei isn't acting like himself..."

"No he's not..." Obito agreed, "What should we do?"

"Nothing," Kakashi replied, "He's treating us like kids, not like ninja. You can't say that you don't enjoy the feeling of Tou-san protecting you and treating you this way! We get to be ourselves for once."

"That's true... and he called all three of us Kit," Rin pointed out, "Does that mean that he thinks of us as his kids?"

"I wouldn't be surprised," Obito replied, "Kakashi's right though, it is nice being treated like the twelve-year-old that I am and not the adult that I need to be."

Rin nodded, "That is true, I like being treated like I'm eleven for once, what about you Kakashi?"

"Tou-san has always treated me like I am my age when we aren't training or on missions, it is rather nice." Kakashi admitted, "Did you notice his changes?"

"You mean his ears and all that?" Rin asked, "I think they make Sensei look cute!"

"I think it's cool," Obito retorted.

Kakashi nodded in agreement as Minato arrived with a tray of cookies.

Kakashi reached for a cookie as Minato was setting the platter down but his hand got a light smack from Minato's tail. "Wait until they are at least on the table 'Kashi-kit." Minato reprimanded almost playfully.

"Sorry Tou-san..." Kakashi muttered as he pulled his hand back.

"Now, I believe my Kits, you had some questions for me?" Minato asked, his eyes sweeping over each child in turn. "Ask away, I shall try not to keep anything from you."

Rin eyed his ears, "Sensei... Why did your features change?"

"I'm not sure myself, although I think my mate is the one that made it happen. I am the only half demon alive. At least according to Mother," Minato explained as best he could.

"Why did you go missing for two months?" Obito asked.

"I was on a Diplomatic Mission to Demon Country for Sandaime-sama, I can't say more on that." Minato replied, "While I was there the King became enamored with me. He started trying to pursue me romantically I believe."

The three stared, causing Minato to shift slightly, "In the end he ended up kidnapping me and I wasn't able to get away for two months, Demons don't understand the purpose of our Heate-Ite, so they thought that it was a necklace of some kind."

"You were wearing it around your neck?" Kakashi asked in surprise.

"Yes, I do that when I am distressed, remember?" Minato replied quietly.

"And... Why were you in the hospital Tou-san?" Kakashi asked.

Minato bit his lip gently, "The King took something from me and forced something painful on me at the same time."

"And what was that?" Rin asked.

"It's called a Bond," Minato explained, "I am already partially Bonded to Kushina-hime so I cannot Bond with a second person. ...Not that the King knew that..."

"That's horrible!" Rin breathed.

"Was that everything you wanted to know?" Minato asked them.

"Almost," Rin replied, "Can we touch your ears?"

Minato's eyes narrowed, "No, only my mate can." Minato got up, "I'm going to go check on her."

Demon's Mate

Minato noticed the sheets stirring as he entered the Master Bedroom. His grin was almost feral as her realized that that meant that his mate was awake. He approached the bed as Kushina sat up with a groan. She was sore everywhere, but it was worth it, especially if it truly helped Minato get better.

Kushina blinked when she was pushed back into the mattress, "Wha...?"

"Good morning My Hime..." Minato purred into her ear, causing Kushina to shudder at the stimulation. His tongue flicked against her throat, causing her to moan quietly in pleasure. "Since the last time was for me... This will be for you..." Minato purred into her ear as he climbed on top of her.

Demon's Mate

Several hours later, when they were pleasantly sweaty and sore, Kushina finally found the breath to ask her questions, "Minato, what's going on with you?"

Minato wrapped his tail around her waist and nuzzled the mark he'd made on her neck, "I'm not really sure, I haven't been myself since I woke up in the hospital. I think I've just been going off of instinct."

Demon's Mate

Kaiko sighed as she entered the compound; she was exhausted; all she wanted to do was go to bed. She blinked when she found the three kids Minato had kidnapped waiting just inside. "What are you three doing here?"

"Sensei called us his kits," Rin replied.

"But that's not important right now." Obito continued.

"Who are you and why are you in Tou-san's Compound?" Kakashi asked.

Kaiko blinked, "I am his mother for one," she told them, "For another, where is Minato anyway?"

Minato's students refused to answer, they didn't know if she was lying or not.

A pained yelp distracted the four.

A second later Minato appeared dressed in just his usual pants and his equipment pouches. He eyed his mother and kits before dismissing them, "Kit's get back inside. Now."

They hastened to obey, but wondered what was going on.

Minato snarled when he saw it was the white haired old man that had barged into his hospital room earlier. He was glad that his seal was working though. Minato's tail swished behind him angrily, "You stay away from us!" Minato snarled. How was he to know that this was his sensei when he was running off of his instincts alone? Which were telling him that everything not in his territory was an enemy?

Kushina came dashing down the lane in nothing but a bathrobe, "Minato stop!"

"Hime he..." Minato stopped when his mate blocked him from advancing on the Outsider.

"I don't care! Sure I'm irritated that we were interrupted as well but you can't kill him! You'll regret it later."

Minato seemed to deflate and relax, "Alright Hime..."

Kushina then turned to glare at Jiraiya, "Leave us alone for the moment Ero-sensei! You interrupted our activities! And no you may not watch; we will not be immortalized in Porn!" Kushina grabbed Minato's arm and pulled him away.

(End)

Yes… Minato and Kushina are enamored with each other! Interrupted Minato and Kushina do not like being interrupted!

Enjoy!
