Most literature aims to uphold moral and ethical values, so you won't really come across stories with such vulgar elements. Instead, you can find stories about love, friendship, and personal growth.
Yes, there are significant ethical concerns. Such a description implies inappropriate and disrespectful content. In any culture, objectifying people in this way is not acceptable. It violates the dignity and privacy of individuals, especially when it comes to a particular ethnic group like Indians. We should respect all cultures and promote positive and respectful representation in all forms of media and storytelling.
Rather than looking for such stories, we can explore great works that deal with themes like love, friendship, and personal growth in a more appropriate way.
I'm not aware of any such inappropriate scene in 'The NeverEnding Story'. It is a family - friendly fantasy film mainly focused on the adventure of Atreyu in the magical world of Fantasia.
Well, a boob expansion story could also be related to a character's growth in a more metaphorical sense. Maybe it's not just about the physical change of breast size but represents a character's development in confidence and femininity. For instance, a young girl in a coming - of - age story might start to feel more confident as she matures, and this new - found confidence could be symbolized in a fictional 'boob expansion' in the story, which is really about her inner growth.
