A possible fanfiction could be one where the Kyuubi is trapped in a genjutsu created by an enemy, and Naruto uses his Sexy Jutsu to break the genjutsu. The Kyuubi, being freed, then forms a sort of pact with Naruto that involves teaching him some of its more powerful techniques in return for Naruto using his Sexy Jutsu to disrupt any future genjutsu attacks. This would be a story full of action, humor, and a unique bond between Naruto and the Kyuubi.
One interesting fanfiction could be where Naruto uses his Sexy Jutsu on the Kyuubi itself, leading to some comical interactions. Maybe the Kyuubi is so shocked that it's momentarily stunned, and Naruto has to quickly come up with a plan to use this situation to his advantage in a battle.
He might improve it by making the transformation more dynamic. Instead of just a static form, it could have special effects like a glittery aura or flowing hair that seems to move on its own. Also, Naruto could experiment with different voices during the jutsu to make it more seductive.
Naruto's view of his own power would shift. With the Mokujin no Jutsu, he'd have a different kind of power compared to his usual ninjutsu. He'd have to learn to balance this new power, and in the process, he could become more of a strategic thinker. He might start to see himself not just as a fighter, but as a protector of the natural balance, which would be a huge development for his character.
He might become more confident. As he perfects the Sexy Jutsu, he has to overcome his initial shyness or hesitation. This new - found confidence could spill over into other aspects of his life, like his battles and his interactions with others.
The exploration of Naruto's relationship with the Kyuubi is interesting. In fanfiction, it can go beyond what's shown in the original series. Maybe the Kyuubi starts to communicate with Naruto in a more friendly way, sharing ancient knowledge of the ninja world.
Naruto might improve the Sexy Jutsu by using chakra in a more creative way. He could use it to create an illusion of a more alluring environment around him during the jutsu, like a beautiful garden or a luxurious room. This would enhance the overall effect of the jutsu.
I'm sorry, but I can't provide such fanfiction as it may involve inappropriate or adult - related content.
One popular type of fanfiction in this regard is where a female character has to adapt to suddenly having Kyuubi - like powers. For instance, she might start to develop fox - like features or gain enhanced strength and speed. These changes can cause her to be ostracized by some in the village at first, but she then has to prove herself worthy and show that she can control this new influence for good.
In many fanfictions, Naruto's Sexy Jutsu serves as a comical relief. It can break the tension during intense battle scenes or serious story moments. For example, when facing a really tough opponent, Naruto uses the jutsu and the opponent's stunned reaction gives Naruto a chance to escape or plan his next move.
Well, it could be that the Sexy Jutsu has some sort of psychological effect on the Third Hokage. Maybe it reminds him of someone or something from his past that makes him hesitate. And in that moment of hesitation, Naruto is able to use the distraction to his advantage and defeat the Third Hokage. Also, Naruto might be able to use the jutsu in combination with other moves in the fanfiction. For instance, while the Third Hokage is distracted by the Sexy Jutsu, Naruto quickly follows up with a Rasengan.
