A possible plot is that there is a prophecy related to Naruto, Kushina, and Tsunade. They have to team up to fulfill it. Tsunade uses her leadership and medical skills, Kushina's unique chakra abilities are somehow passed on to Naruto during the adventure, and they all grow as characters while saving the village from a great threat.
Perhaps a story where Naruto discovers a hidden scroll left by Kushina that contains a powerful jutsu. Tsunade helps him decipher it, and along the way, they learn more about Kushina's past and her relationship with the village. They might also face some enemies who are after the scroll.
One idea could be a story where Kushina comes back to life briefly and shares her old stories with Naruto and Tsunade. This could include tales of her time as a kunoichi and how she met Minato. Another plot could be a training arc where Tsunade trains Naruto in a special medical - ninjutsu technique that was once known to Kushina.
A fanfic where Tsunade and Kushina train Naruto in a new and unique form of ninjutsu. They take him to a secret location and over the course of the story, Naruto masters this new skill. Along the way, they share stories and experiences, strengthening their bond as comrades and friends.
Perhaps a plot where Kushina is brought to the Fairy Tail world where Erza is from. Naruto, who has some connection to this strange event, follows. Erza takes Kushina under her wing, teaching her about the magic in this world. Naruto tries to adapt and in the process, he and Erza form a unique friendship. They then have to face a great threat in the Fairy Tail world together with Kushina's new - found magic skills.
A fanfiction could center around a family training session. Minato trains Naruto in advanced ninjutsu techniques while Kushina teaches him about the Uzumaki clan's secrets. This would not only strengthen their family bond but also make Naruto an even more powerful ninja.
One idea could be a time - travel fanfiction where Sakura somehow travels back in time and meets Kushina.

In a Naruto, Kushina and Tsunade lemon fanfiction, the plot might start with Naruto having dreams about his mother Kushina. Tsunade, noticing Naruto's distress, decides to help him understand these dreams better. As they dig deeper, they find that Kushina was involved in some ancient prophecy that now involves Naruto as well. As they face the challenges related to the prophecy, their relationships grow closer. The 'lemon' aspect could be expressed through some tender and somewhat romantic scenes between Naruto and Tsunade, while also having a strong emotional connection to Kushina's memory. This could lead to a story that is both about self - discovery for Naruto and an exploration of complex relationships.
Perhaps Naruto gets injured severely during a battle and Tsunade has to use all her medical skills to save him.

This could lead to a new level of respect and friendship between them in the fanfiction.
A plot could involve young Tsunade being in a difficult situation where she loses confidence in her abilities.
