Maybe Naruto is sent on a mission to a far - off land where Tayuya and other female characters are living in a sort of commune. He initially goes there for a diplomatic mission but ends up getting involved in their daily lives. His kind heart and strong ninja skills attract the women, and a harem situation gradually unfolds as he helps them solve various problems in their community.
A possible plot could be that Tayuya is on the run from some dark forces. Naruto, being the hero he is, offers her protection. Along the way, they meet other female characters who also need help. Naruto's selfless acts draw them all to him, and as they travel together, a harem - like relationship begins to develop. They all learn from each other's ninja abilities and grow closer as a group.
One idea could be that Naruto, through some strange ninja magic accident, finds himself in a situation where he has to protect Tayuya and a group of other female ninjas. As they go on adventures together, a harem dynamic starts to form. He could teach them his unique ninja ways, and they in turn, start to develop feelings for him.
