“I’m going to teach you about a powerful jutsu, passed down for generations. Only the most powerful kunoichi can master it. As simple as it seems, it takes massive chakra control.”
“Kunoichi? But I’m a guy!” Naruto complained.
As if she didn’t notice. “Oh, I realize that. But what about your Sexy Jutsu? With a talent like that, you should learn kunoichi skills of seduction, and I shall teach you. But that is for another time, first, I’ll demonstrate this jutsu on your male body, and if you manage to survive…” she trailed off, grinning. “I may teach it to you.” If he was a good boy she would, after locking him into a girl’s body for a time, force him to live as one and all that entails. But, first things first.
Naruto hesitated, but nodded. “Anything that would make me more powerful!”
“Very well,” she stood and slipped off her clothes. She wasn’t wearing any underwear, so she went from fully clothed to nude in one instant, causing Naruto to fall to the floor gaping.
“Baa-chan?”
“No! Does this look like a baa-chan’s body to you? I am Tsunade-sama, do you understand?” He always acted like a kid, but now maybe she could use his hormones to try to put him in line, and make a man out of him.
“Yes, Tsunade-sama,” he whimpered, body shaking. From the looks of things, he was quite excited; the bulge in his pants was immense for a boy his age.
“Now then, on to training,” She put her hands together and formed a dozen complex hand signs. “Futanari no jutsu!”

Naruto couldn’t believe what he was seeing, not only did Tsunade strip in front of him, she was growing a cock. A huge one, it had to be a foot long as least! “What—what is that!?”
He couldn’t move, his legs quivering too much to stand. Tsunade cackled and walked towards him, stopping only a foot away. Her pussy was inches from him, but the dick hovering just above his head overshadowed it greatly. “It’s exactly what it looks like, a penis. Bigger than yours, I’m sure.”
Naruto finally found the will to try to crawl away, but a hand grabbed his hair, pulling him back. “Thought you wanted to train with me? Trying to run away already, without even giving it a try? Your mouth would suffice for now; it would be much easier on you if you cooperated.
