Becoming kurama’s

"Well, I believe that your bladder is full of my cum now as well, isn't it? You probably feel like you need to pee because of that. I will reward you and let you choose where you want to dump my precious cum. You can choose anything, even something like my muzzle or ass. You have my word." Kurama explained.

Naruto did indeed feel like he desperately had to relieve himself. He did not need to think long about an answer.

"Thank you, master. I think I know exactly where I want this cum to go..." Before he finished his sentence, a realisation dawned upon him.

"Wait a second... I HAVE A KNOT???"

Both Kurama's laughed audibly at their stupid kit.

"Hehe let's come back to that later. I really need to pee now..." Naruto sheepishly said as he stood on all fours.

"Well you just said you knew exactly where to dump that cum in your bladder. Where'll it be?" Light Kurama asked, walking slow circles around Naruto's foxy and latexy body. When he got to Naruto's behind he gave a playful lick over his new properly-sized balls, earning him a shudder from the kit.

"I kind of want it to return to where it came from..." Naruto eventually said. Kurama narrowed his eyes suspiciously.

"Explain." He commanded.

"I mean-uhhh, like, back in your balls, master. Like, how you made my balls bigger... " Naruto said as a blush somehow appeared on his face.

"So let me get this straight. You want to piss in my cock?" Kurama asked, still looking suspiciously at Naruto.

*nod* *nod*

"BWAHAHAHA it looks like my little kit's balls did not just grow physically! Look at you, asking the mightiest of bijuus if you can piss in their junk." Kurama ridiculed Naruto's request. Naruto closed his eyes tightly, knowing he must have said something wrong to get such a reaction. Kurama started tearing up in laughter.

"And here I thought I was the kinky kitsune. Very well, I accept." The light fox then said flatly.

"Huh?" Was Naruto's smart reply, confused by the sudden change in demeanor.

"Well I did say you have my word, and I intend to keep it." Kurama moved to sit in front of Naruto, putting his balls and cock on display for Naruto once more.

"Besides, we have just the thing." Dark Kurama added as he sat next to his counterpart. Dark Kurama snapped his fingers and a hollow tube appeared in his paw. It basically looked like a flexible transparent straw. Naruto's blush intensified.

"Uhmm... What do you mean? What is that?" Naruto asked.

"Well, it will make it easier for you to return all the cum in your belly to its creator." Dark Kurama replied.

"I'm ready, just show him." The foxes grinned. Without further ado dark Kurama pumped the tube he was holding in his own ass a couple of times. The tube was not very wide, so he barely felt it.

"There, that should have lubed it up enough. You really came a lot in me. Even after filling the kit's balls there is still quite some cum in my ass." Dark Kurama noted. He then grabbed the light fox' cock and checked that Naruto was watching. Which he was. Intently. The fox then brought his other paw, the one with the lubed-up tube, over to the cock tip.

Dark Kurama squeezed his counterpart's cock tightly to make the opening widen. Slowly, he started inserting the tube in the tapered tip. The tube fit perfectly.

"Ooohh that's a new one." Light Kurama commented on feeling a tube being shoved down his urethra for the first time. "Go deeper, I need more!" He commanded.

"NGH I can feel it too, don't worry!" Dark Kurama replied, making clear that he still shared the sense of touch with his counterpart. Inch after inch of tube disappeared in the vulpine shaft. The sensation Kurama got was strange, yet intoxicating. Naruto watched in fascination as he saw his master's cock swallowing the straw.

Dark Kurama made sure that the tube went down the ejaculatory duct so it would end up in his balls. Eventually Kurama felt the tube reaching his balls and stopped pushing the thing inside. About ten centimeters of the tube was still outside. The end widened in a cone shape to make sure that Naruto could aim properly.

"Whew we really should have done that before sometime. This feels nice already and we haven't even really started!"

*WHA!*

Naruto yipped as he was suddenly pushed on his back by dark Kurama.

"Sorry kit, but this makes things a bit easier for lighty over there." Dark Kurama explained his sudden action before nodding in the other fox' direction.

"Speaking of lighty, come over here and sit on his chest, would you? I cannot wait!" The lighter fox agreed, stood up and walked over to Naruto. Naruto saw the bit of the tube poking out from his master's tip as the cock swayed from left to right a little while the kitsune made his way over to him.

Since Naruto was laying on his back, his cock pointed towards his head. Light Kurama sat his bottom down on Naruto's chest lightly with his back towards said kit's head as well. This made their vulpine members point towards each other. Naruto could not see much of the action, since he was looking right at his master's back and nine glorious tails.

"Khehehe I must say I am quite eager as well. Are you ready, kit? Ready to fill your master's balls with his own cum?" Kurama teased as he grabbed the end of the tube extending from his cock hole with one paw and Naruto's vulpine cock with the other. He inserted Naruto's tapered tip into the end of the tube, making sure the tube's opening was sealed.

"Yes master!" Naruto said as he felt his cock being put into position. "Can I start?"

"Yes, and don't hold back! I want to feel my cum rushing the other way for once!" Kurama demanded.

"Here comes!" Naruto warned as he stopped holding back. At once, both Kuramas saw a torrent of their cum rushing from their kit's cock and into the tube. Kurama strangely did not feel much as he saw it enter his own cock. He did feel his urethra getting warmer as the warm cum flowed through the tube. He felt his own liquid go deeper and deeper inside him, until...

"AAHHHHH!!" "WHOOAAAA!!" Both Kuramas roared as their own cum once again met with their epididymis (where sperm is stored). They have never felt that before. The feeling of cum entering their balls instead of exiting was exotic.

"Does it feel good, master?" Naruto asked.

"Keep going, kit! I can feel my balls expanding and it feels GOOD. I need MORE!" Was Kurama's clear answer.

"I still have a lot more in me!" Naruto replied.

"Khehehe," Kurama chuckled evilly "Well then GIVE IT TO ME!" Kurama shouted as he pushed with his paws hard on Naruto's bladder.

"AAHH" Naruto yelled. Not out of pain, but surprise. The effect was instant. The pressure of the fluid leaving Naruto's cock was increased massively by Kurama's actions, and so it also entered Kurama's foxhood faster. In fact, Kurama saw his balls increase in size as he pushed down.

"AHH, yes! Give me my kitsune spunk back!" Kurama moaned as he saw his old cum rejoining him. After his little stunt, though, he quickly felt the pressure decrease.

"Sorry master, but I think that is all. That was intense... Almost as intense as being on the receiving end."

"It's okay, kit. You have done very well." At this point, Naruto's bladder was completely empty.

"Khehe I have to agree. That was something else! To watch and to feel!" Dark Kurama chimed in. "Now for the finale..." The dark fox grinned as he removed Naruto's cock from the end of the tube. The tube itself was still filled with cum, which just wouldn't do in Kurama's opinion. Light Kurama stood up from Naruto's chest and Naruto himself also got on all fours.

"Finale?" Naruto questioned.

"Of course, we still need to get that tube out. But first we have to make sure that all the cum is inside." The dark fox explained as he crouched under his counterpart and took the bit of tube sticking out of the nearby vulpine cock in his mouth.

"Khehe I suppose this is the first time we give ourselves a literal blowjob!" Light Kurama joked. "Now blow me!" Immediately the darker kitsune below him started blowing the air out of his lungs and into the tube. This resulted in the last bit of cum being dumped in the light fox's balls. Light Kurama started purring as he felt his balls enlarging further. Meanwhile, Naruto wanted to participate a little and walked behind the fox.

"NGH?!" Light Kurama reacted as he felt a tongue licking his swollen balls.

"I couldn't just stand there and watch, could I?" Naruto explained.

"Keh I suppose not kit. Keep licking. It feels rather nice, like a massage." Kurama encouraged his kit, while the last bit of cum flowed out of the tube.

"There we go, all done!" The dark fox declared.

"Good, now pull the tube out slowly. Kit, keep licking!" Light Kurama ordered. The other two did as they were told. Dark Kurama bit down on the tube and started backing away slowly. It was easier to pull the tube out than it was to put it in, so it didn't take long until the whole thing was removed.

"Whoa I have never seen a cock opening gaping like that!" Dark Kurama exclaimed upon seeing the light fox' wide cock hole.

"Well I suppose that was inevitable. It'll go back to normal after we rest some."

Naruto decided to take a look as well and was just in time to see the widened opening. The kit whined a little as he saw his master finally lose his erection for the first time since Kurama was still in his gigantic size. On the other hand, it was still a sight to behold to see his master's cock snuggling back into its furry sheath. Naruto was so focused that he did not even notice that he was getting flaccid himself as well.

"Khehe do not be too sad, kit. He'll come back after we take a nap." Naruto's tails wagged at that. "Also, there is one last thing." Naruto tilted his head questioningly.

"You see, although that suit is already much better than your human body, it is still not the real thing." Naruto looked down in disappointment. He knew it was true.

"But I can fix that if you want." Naruto's fake tails started wagging harder.

"Please do master! I want to be a real kitsune like you!" He said excitedly.

"Very good, I counted on that. I just need to concentrate my chakra in you for a while, preferably while you are close to my body. So I was thinking I could fix you while you just rest for a bit. Now, since you well become an actual real kitsune, you will lose some tails, but at least they'll be real. It's up to you to get them back by becoming stronger, understood?"

"Of course, master!" Naruto yipped happily. He's never felt this happy in his life.

"That's what I wanted to hear, now excuse me while I get back to normal." With that said, light Kurama started growing back to his old size before laying on his side.

"'I'll dispel for now, otherwise I'd only be a distraction." Dark Kurama said as he walked up to Naruto and gave him a lick over his muzzle, earning him a sad whine from the kit.

"Aww don't be sad, little kit. I'll surely be back soon." The fox cooed, and in a poof he was gone.

"Now let's continue." The giant fox said. "As I said, you should get as close to me as possib-WHOA!?" He did not pay attention to Naruto as he was speaking and a sudden feeling from his sheath caused him to stop mid sentence. He looked at his member and saw Naruto struggling to get in his sheath.

"BWAHAHA I suppose that'll do, kit! I suppose you and my cock are starting to become inseparable." Kurama laughed as he helped Naruto get in by pulling his sheath back a bit to expose his tip. Naruto took this chance to lay down on his master's foxhood before Kurama rolled his sheath back, covering Naruto with it like a blanket.

"Now sleep tight, little one, while I make you a beautiful young kitsune."

"Sleep well, master." Naruto replied while sleepily closing his eyes. He was incredibly comfortable, surrounded by Kurama's musk and touching the gigantic warm cock and sheath at the same time.

'Now let's get to work.' Kurama thought to himself as he too closed his eyes to focus better. The suit he gave Naruto already made his body the right shape. Now he concentrated on making the suit one with the kit, and changing the suit in actual skin with fur.

Kurama made a clear picture in his mind of what he wanted Naruto to look like. Naruto would probably have enough power for four tails right now. His fur would be like his own, but lighter and more yellow. Naruto's eyes would be slitted like his, but that beautiful blue they already were. The fur around his eyes and up into his inner ears would be the same black as him. It was one of his most defining features that he wanted his kit to have.

The fox smirked as he thought of his kit's naughty bits. He already gave Naruto's balls a size up today. 'Khe, and wasn't that fun?' He mused. With his balls, Naruto would have a cock to match: Large, but relatively a bit smaller than his. He couldn't give his kit a larger cock than his own now, could he? Lastly, Naruto's ass would be tight, but highly stretchable. He wanted the kit to feel as tight as a virgin whenever he'd penetrate the kit for the first time in a session, but near the end of said session, Naruto should be able to easily take his knot and then some.

Satisfied with the mental picture, Kurama started carefully shaping Naruto's body like he wanted. He couldn't wait to see his work...

A couple of hours later...

"Wakey, wakey, kit." Kurama said as he nuzzled the tiny snout hanging out of his sheath with his comparatively massive nose.

"Hhmmpgdontwannagetupyetmmhhmf" Naruto half consciously whispered.

'Keh, he looks kind of adorable like this.' Kurama thought to himself before a devilish grin appeared on his muzzle. 'I know just how to wake him up, khehehe.'

Kurama started thinking of everything he's done to Naruto so far. That made him rather aroused again. Knowing that he'd be able to fuck another real kitsune beside himself for the first time real soon aroused him even more. His arousal quickly became apparent as Naruto's "bed" started moving.

'Wha-What's happening?' Naruto thought in his hazy state. He felt himself being moved from under the covers of his master's sheath. It took a second for Naruto to realise that he took a nap on Kurama's cock, which was currently growing.

"BWAHAHA my dumb little kit. Good morning sunshine." Kurama teased. This time, Naruto was awake enough to process his master's words. Then, he remembered yesterday's activities and if Naruto's face was not covered in fur, you could see him start to blush.

"Wait a second!?" Naruto yelled as he looked at and touched every part of his body, including his four real tails. "Master, it worked!?"

"Of course, kit. I am not the kyuubi no kitsune for nothing." Kurama answered with a proud smirk.

"Thank you so much, master! Could you ehm... shrink again so that I can hug you?"

"Well I can certainly do that first part..." Kurama started shrinking again after putting Naruto on the ground. "But I think I deserve something more than a simple hug, don't you think?" Kurama finished as he stood at an angle in front of Naruto, emphasising his now free and hard shaft. It looked obvious that his balls had a lot of spunk ready to go.

"Whatever you want, master!" Naruto yipped.

"Good, because today we will explore every bit of your new kitsunte body." Kurama declared before he licked his black lips and a bead of precum dripped from his cock.
