For Sakura, she could grow in terms of her leadership skills. If they encounter any difficulties in the forest like being chased by a group of wild animals or getting caught in a dangerous situation, she could step up and lead the way out. Sasuke might then realize that Sakura has the potential to be a great leader. And for Sasuke himself, he could become more open to the idea of a relationship with Sakura. The seclusion of the forest could provide the perfect backdrop for him to explore his feelings for her.
In some fanfictions, there are scenes where Sakura is in danger and Sasuke realizes just how much she means to him. For example, if Sakura is injured while protecting Sasuke, Sasuke's reaction of guilt and his newfound determination to always be by her side can be an extremely emotional part of the story.
The relationship often becomes more strained. Sasuke's punishment can make Sakura feel resentful at first. But over time, it can also lead to her becoming more independent as she tries to prove herself to him.
In such a fanfic, it might explore the challenges they face. For example, Sasuke's past actions might make some in the village still be wary of him. But Sakura's pregnancy could be a symbol of hope and new beginnings. It could also show how their friends like Naruto react to the news. Naruto, being Sasuke's long - time friend, would likely be overjoyed and offer his support, while also teasing Sasuke about becoming a dad.
In such fanfiction, their relationship could be shown as a complex web of emotions. They might have a lot of unspoken feelings that surface in the 'dark' situations they face. For example, when they are in a dangerous battle, Sasuke might show his protective side towards Sakura in a more aggressive way than usual, which could lead to some intense moments between them. The 'lemon' aspect could add a layer of physical passion to their relationship, but it should be done in a way that still respects the characters' core personalities.
She could also try to find Sasuke and clear up any misunderstandings. Sakura is not one to give up easily, especially when it comes to someone she loves. She might set out on a journey to find him, believing that she can bring him back and make him realize the importance of their family.
Sakura would probably be initially very angry. She has strong feelings for Sasuke, but kidnapping is a very extreme act. So she would likely fight back, using her medical ninjutsu skills and combat abilities to try and escape.
In fanfiction, Sakura giving Naruto a massage could be a sign of her caring for him. It might be a moment of relaxation for Naruto, who is often so busy with his ninja duties. This scenario could also be a way to explore their relationship further, perhaps showing a more tender side to their friendship.
The dynamic would be turned upside down. Sasuke would likely become more of an outcast or a loner, feeling rejected. Naruto would be in a difficult position, having to balance his friendship with Sasuke and his new relationship with Sakura. Sakura would be the catalyst for this change, and she would have to face the consequences of her actions, like dealing with the villagers' opinions and the potential backlash from Sasuke's supporters.
I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide range of themes and interpretations, but a 'perverted' aspect might not be in line with the general positive and creative nature of most fan works. It's possible that there could be some out - there that distort the characters in this way, but it's not a common or recommended type.
