“Let go! I did nothing wrong!” Naruto yelled, struggling to free himself from the two men that dragged him into Tsunade’s office.

“Calm down Naruto they brought you here for a specific reason,” Tsunade said to him as he was locked inside her office with her. “As you know this will be the last year that I rule as Hokage. Next year Kakashi will take over, though I doubt that he will do a good job given his personality. You are 20 years old and in several years you will be Hokage yourself, but frankly, you’re an idiot. You have the ability to draw people to you, but that doesn’t mean that you will be a good Hokage.”

“What are you talking about? Isn’t that why I have to do all these classes?” Naruto asked her, curious as to what she was implying.

“Yes, yes, that was the plan, but I can see now that it was foolish of me to think that someone other than me could be Hokage. Kakashi is one thing since he does not plan to remain Hokage for long, but you, I doubt you would do the same. No matter though I have already discovered a way to help you become the best Hokage that you can be~.”

“Really? That sounds amazing~!” Naruto said. True Tsunade did just insult him, but if she did that just to tell him that he could improve then he was fine with that. “So, what do you have in mind~?”

“I actually have two methods in mind, but it’s hard for me to choose, so how about we gamble for it~?” Tsunade said to him, showing off her Hoakage headdress, knowing that soon she would have the perfect successor. With her help, Naruto could become Hokage and she could finally have what she wanted~.

“Gamble?” Naruto asked, knowing that gambling was a bad hobby of Tsunade’s. He was worried about asking what sort of gamble it was, but luckily for him, he didn’t even have to ask.

“That’s right~,” Tsunade said to him, pulling out a two-sided coin from her cleavage. “Since this is your first time, I’ll make things simple for you. All you have to do is pick heads or tails and whichever side it lands on will choose my method of training you~.”

“Fine, but why do I have to choose?” Naruto asked her, feeling as if there was something that she wasn’t telling him. “If I say tails and it turns out to be heads then what happens? And what are these methods that you’re talking about?”

“The methods are secret~,” Tsunade said to him. “Though when it comes to your choice and the result, the answer is easy. If you  pick right then you experience a more pleasurable experience If you choose wrong there will be a look of resistance on your end, but who’s to say if you will eventually start to like it~.”

“Fine then I choose heads,” Naruto said to her, hoping that he wasn’t making a terrible mistake.

“Good~. Now, let’s begin~,” Tsunade said flipping the coin up into the air, and then catching it when it came back. “Fufufu~,” Tsunade laughed when she saw the result. You see it never matters what side Naruto chooses because the results would have been the same. There was only ever one choice, but Naruto had yet to see that. Rule one when gambling, always know what you’re gambling for. This was something that she would most certainly have to teach her soon-to-be twin~.

“Oh, would you look at that~, it’s tails~,” she said with a smug look across her face. “How wonderful~. Though this means that you lose~. Now I guess we have to do this the harder way~,” she said standing up from her desk and slowly making her way around toward Naruto~.

“Fine, I lost, so what,” Naruto said, still unaware of what was about to happen. “This means that I have to do it the hard way. That’s fine by me. I didn’t get where I am today by doing things the easy way. So, tell me already, how do you plan on helping me become a better Hokage?”

“Fufufufu~. That‘s the exact kind of attitude that I want to hear~,” Tsunade said, pressing her fat tits up against Naruto’s chest making him blush from embarrassment. “Though what’s the point f telling you when I would rather show you instead~. Tsunade’s lips were so close to Naruto’s that they were almost kissing. Naruto wanted to move away from her, but it was already too late.

“Tsunade, why? Why can’t I move?” Naruto asked, trying his best not to accidentally kiss Tsunade, but resisting was futile.

“That’s because of this little thing~,” Tsunade said, opening up her cleavage to reveal that there was a forbidden curse mark. It was only temporary and could only be used once, but once was more than enough~. “With this curse mark, I shall transform you into a great Hokage~. I shall transform you into me~.”

“What are you talking about? This isn’t funny! Let me-mmmmmppphhhh~!!!” Tsunade shoved her tongue down Naruto’s throat, wrapping her tongue around his as she did. She needed him to understand what was going to happen couldn’t be stopped~. As she continued to make out with him she slowly started to take off his jacket and then soon his shirt. Her saliva dripped out of Naruto’s mouth as he was unable to say a singular word to express how shocked he was.

“Fufufu~, that’s right, just stay still like that and accept my love~. If you do then this won’t have to be the hard way~,” Tsunade said teasing him. “Look even your “tailed beast” is agreeing with me~.

“Wh-what…what are you doing~?” Naruto asked, feeling hot and irritated right now. How dare she assault him like this?

“Aww, it’s cute that you think that I need a reason for showing my love,” Tsunade said, whipping the drool from Naruto’s mouth with her finger before having a taste of it to his horror. “Though I guess that you are right~. There is a simple reason for this. I want you to become my successor, and the only way for that to happen is for you to become me~. Trust me, things will be much better for you if you accept this gift~.”

“Gift? Are you insane!?” Naruto yelled at her. “I’ll never let that-what!? Stop that! Don’t!” Naruto yelled as she removed him of his pants and undergarments, showcasing his tiny “tailed beast” for her to see.

“Pfft~! I’ve barely even started and it seems that you little “tailed beast” is more than eager for me to continue~,” Tsunade said, teasing him some more.

“Shut up! I’ll-mmppphhh!”

“Mmm~, you’ll what?” Tsunade said slowly biting Naruto’s lower lip while making out with him. She gleefully watched as his blonde hair turned lighter, the same shade as her own. “You-mmm~, belong to me now so you best not resist~.”

“N-no! I-ll-ahhhhh~!!!?” Naruto moaned as shocks of pleasure rippled across his body as she slowly ran her hands down his bare chest. His heart began to beat faster, and his body became hotter.

“You love it don’t you~,” Tsunade said, mocking him. “Go on admit it~,” she said slowly squeezing his breasts and pinching his now-sensitive nipples, which had started to swell~.

“Ahhhhhhh~!!!” Naruto moaned out unable to realize that his voice was getting higher and more mature, just like Tsunade’s. He tried to fight back against the effects of the curse mark, but nothing he did worked. Even the tailed beasts inside of him did not answer his call for help. They have all sealed away once more, unable to help their friend.

“That’s right, you like this don’t you~?” Tsunade said teasing Naruto, biting his lip some more, allowing it to grow plumper and sexier.

“N-no…I…I-ahhhh~!!!” Naruto tried to deny Tsunade’s words, but he soon found himself moaning as his face became more feminine, resembling more and more of Tsunade as time went on.

“Come on, let’s enjoy ourselves~,” Tsunade said to him, pinching her bright pink nipples some more, causing them to become erect as they continued to swell~.

“Ahhhhhhhh~!!!! Please! N…more~!!!” Naruto moaned out, unable to speak properly, feeling the weight of his chest start to become heavier and his new breasts became bigger.

“Hehehehe~. Well if you insist~,” Tsunade said, lightly biting Naruto’s left breast and It finally completed growing into a pair of K-cup breasts~.

“Ahhhhhhhh~!!!!!!!” Naruto moaned out again, no longer able to think straight as Tsunade began jiggling his nice breasts up and down, sending jolts of pleasure throughout his body~. He never wanted this feeling to end, but he knew that this wasn’t him…or was it? Is this something that he truly wanted?

“See~, you can’t resist~,” Tsunade said licking her lip and moving down to Naruto’s lower parts~. “Now let’s see what we can do here~.”

“Tsu-ahhhh~!!! Please! Stop~!!!!” Naruto couldn’t help but moan over and over again with each movement of her mouth and tongue~. She squeezed his ass, slowly expanding his ass, hips, and thighs soon engulfing his manhood, welcoming her to the glory and honor of becoming Tsunade’s twin~.

“Ahhhhhhhh~!!!!” Naruto climaxed as Tsunade finished up, shoving her wet and juicy tongue into Naruto’s mouth, letting her new twin have a taste as well~.

“Go on there is no need to stop yourself~,” Tsunade said, seeing the troubled look across her twin’s face. Naruto couldn’t think properly, and her mind was a mess. She couldn’t even remember why Tsunade was doing this. Had she always been a woman? Had she always looked like this?

These questions flooded her mind, but soon they would no longer be just questions. Soon they would be the truth, well at least to Sunna they would be~

“My dearest sister~, look at you~, how could you be naked in here~?” Tsunade said to her sister knowing that this would happen.

“I am?” Nar-Sunna asked herself, strangely keen to listen to Tsunade’s words. Wait…were they sisters? She didn’t know what to do. Her mind was telling her to run, but her body wouldn’t move and it felt so good to be next to her twin~.

“Fufufu~. Silly Sunna always playing games~.” Tsunade said bringing out a pair of clothes that she had stashed in her office for this occasion~. “Here let me help you put these on~,” Tsunade said, getting on her knees, before pulling a black thong right up Sunna’sa new womanhood, giving her a tight wedgie up her crotch~!

“Ahhhhhh~!!! S-sister~!!!” Sunna moaned, starting to feel more and more like Tsunade as time went on.

“That’s right, you’re a good girl. A good sister~,” Tsunade said, whispering her hot breath into her sister’s ear. “Hmm instead of getting dressed how about we have some fun instead~?”

“Y-yes~,” Sunna said innocently as her twin dragged her to her personal chambers adjacent to her, or rather their office~.

-1 Year  Later-

“Ugh! Sister I lost again!” Sunna yelled just losing yet another gamble she made at the casino. “Can I have more money~?”

“Why of course you may my precious sister,” Tsunade said to her handing her some more coins. “We must make a proper gambler out of you yet~. Remember sister this is all for your training to become the perfect Hokage~.”

“Yes, sister~! I will do as you command~!” Sunna said to her. She had forgotten all about her time as Naruto and was more than happy to do as her elder twin sister asked of her. She would be a great Hokage one day, but that would have to wait for a few more years, until then it was time for her to have fun~!!!
