One possible reason could be puberty. Hormones like estrogen play a big role in breast development during this time. Another reason might be weight gain. If your friends have gained some weight, it can also lead to an increase in breast size as there is more fat deposition in that area.
It could be normal growth, especially during puberty when hormonal changes can cause breast development. If it seems sudden or extreme, it might be due to factors like weight gain or certain medications. However, it's important to consult a doctor if there are concerns to rule out any underlying health issues.
Growing or creating erotic fiction can be a very controversial and inappropriate activity within a marriage. It may involve creating content that goes against moral and ethical norms, and can also have a negative impact on the relationship and family environment.
It could symbolize new life and nurturing. In many stories, a woman with full breasts of milk often represents the ability to care for a new - born, whether it's a biological child or a symbol of new beginnings in a community.
This can be a plot point in several ways. For instance, in a story set in a traditional society, it might trigger a series of events related to the celebration or protection of the new mother and the new - born. The family might start making arrangements for the proper care of the mother and the baby. It could also be a plot point in a story where there are conflicts around the mother's role. Maybe there are others who are jealous or have different ideas about how the mother should raise the child, and the fact that her breasts are full of milk becomes a central aspect of this conflict.
This kind of statement in the story could potentially be a form of hyperbole. Maybe it's used to create a shock factor or to emphasize a character's transformation in an extreme and perhaps comical way. However, it's not a very common or tasteful way of expressing things.
Stories should be about the development of characters in a healthy and respectful way. Having a title that emphasizes a girl's body parts in an erotic context is not in line with good values. We should encourage stories that celebrate the whole person, including their personality, dreams, and achievements.
