Well, I'm not sure if there are many such fanfictions. But it could be really interesting. Maybe it would involve Naruto and Ty Lee having some kind of adventure in the Avatar world, with the lemon aspect perhaps adding a bit of romantic or spicy undertones. However, it might be a bit of a stretch to combine these three different universes in a single fanfiction in a believable way.
Well, one possible plot could be that Naruto somehow gets transported to the Avatar world and meets Ty Lee. They might team up to fight against some common enemies, like the Fire Nation's rogue soldiers. Naruto could teach Ty Lee some of his ninja techniques, and in return, Ty Lee could show Naruto the unique bending arts of the Avatar world. Maybe they would have to work together to stop a dark force that's threatening both their worlds.
Character growth is also a big theme. Writers might show Ty Lee's journey from being part of Azula's group to finding her own identity. For example, she could be learning new skills or developing new friendships outside of her old circle. And of course, there are often themes of love and friendship, as she forms new relationships with other characters in the Avatar universe.
An adventure to a mysterious island could be another possibility. The island is said to have magical properties that could enhance their abilities. Katara hopes to become a stronger water - bender, and Ty Lee wants to improve her acrobatic skills. On the island, they encounter strange creatures and puzzles. They have to rely on each other's strengths to overcome these obstacles and in the process, have an unforgettable adventure together.
Their abilities could merge in combat situations. Naruto has his Rasengan, a powerful spinning ball of chakra. Ty Lee could use her acrobatic skills to get Naruto into the perfect position to use the Rasengan against an enemy. Meanwhile, Ty Lee's ability to sense and block chi could help Naruto when he's facing opponents who use energy - based attacks. He could learn from her how to disrupt the flow of such attacks. Also, Naruto's shadow clone jutsu could be used to create distractions while Ty Lee sneaks up on the enemy to perform a chi - block.
The plot might involve Naruto and Ty Lee teaming up to fight against some common enemy in the Avatar world. Along the way, they discover new powers within themselves and in each other. The 'lemon' part could be expressed through their growing attraction, with some passionate moments shared during their journey, like a stolen kiss during a dangerous situation or a tender moment by a campfire.
You can try fanfiction websites like Archive of Our Own (AO3). There are a lot of Avatar fanfics there, and you can specifically search for ones related to Ty Lee. Just type 'Ty Lee' in the search bar and browse through the results. Many talented writers share their works there.
One interesting story could be about how they first met. Maybe it was during a big gathering in the Avatar world. Katara, being from the Water Tribe, was initially cautious around Ty Lee, who has a very different and energetic personality from her own. But as they got to know each other, they discovered that they both have a strong sense of loyalty, Katara to her friends and family, and Ty Lee to those she cares about. They might have bonded over their shared experiences of trying to find their place in a world filled with conflict.
In Ty Lee lemon fanfic, the writing style can vary a great deal. Some may be more descriptive, painting vivid pictures of Ty Lee's actions and expressions, especially during the lemon - related scenes. Others might focus more on the emotional journey. The fanfic often tries to stay true to Ty Lee's roots as a character from the Avatar series while also adding new elements through the lemon aspect. For example, it could explore how her traditional upbringing in the circus clashes or combines with the more adult - themed elements in the story.
One common theme is friendship. Ty Lee's relationships with the other characters, like Azula and the rest of the group, are often explored in different ways. Another theme is self - discovery. Since she has a unique personality, fanfics often focus on her finding out more about herself.
