No. These types of fanfic are not considered appropriate in mainstream literature. Mainstream literature typically focuses on more general themes like love, adventure, historical events, and social issues. Breast expansion and penis expansion fanfic are very specific and often have sexual undertones that are not suitable for a general audience.
I'm not aware of any scientific or legitimate stories specifically about 'cock growth' in that sense. However, in the case of breast expansion, there are some medical conditions like hormonal imbalances that can cause changes in breast size. For example, during puberty, hormonal changes lead to breast development in females. Also, certain medical treatments or medications might have an impact on breast tissue, but these are all within the realm of normal medical processes.
Macromastia breast expansion fantasy stories often explore the concept of extreme breast growth in a fictional context. These stories can range from the magical to the scientific in their explanations. Some might involve a magic spell that causes sudden growth, while others could be based on some sort of experimental serum.
One reason for the popularity of macromastia breast expansion fantasy stories could be the element of the unknown and the extreme. People are often fascinated by things that are out of the ordinary. These stories offer a unique take on body transformation.
Since Ahri is a character (maybe from a game or some other media), a 'breast expansion fanfic' about her is a work of fan - made fiction that focuses on this character. The 'breast expansion' aspect is a rather odd and probably not - so - common theme. It could be the result of some fans' very specific and creative, albeit a bit out - there, ideas for exploring the character in a different way. It might also be part of a sub - genre within the fanfic world that caters to very particular tastes. However, it's not something that is widely known or accepted in the broader literary sense.
In fanfic, 'breast expansion' is a fictional concept often used in certain types of fan - created stories where a character's breasts grow or expand in an exaggerated way. However, 'dick growth' is also a rather strange and inappropriate concept in this context. Fanfic often explores various out - of - the - ordinary or fantasy - like scenarios, but these can be quite extreme and not suitable for all audiences.
Breast expansion fanfic may involve themes like the impact of sudden or gradual breast growth on a woman's life, such as her clothing choices, social interactions, or self - esteem. It might be set in various fictional scenarios, from magical to scientific. Penis expansion fanfic, in a similar vein, could explore how a male character copes with such a change, perhaps in terms of his sexual confidence or how it changes his relationship dynamics. But it's important to note that these are very specialized and not widely - accepted forms of fan - created content.
It could be a fictional story about a friend's physical transformation in a positive or perhaps a magical context. Maybe it's about a friend who gains confidence as her body changes in a way that makes her feel more beautiful.
In a far - off land, there was a kind fairy. The fairy noticed a poor woman who was always sad because she was very thin and had a flat chest. The fairy decided to help. Using her magic, she made the woman's breasts expand gradually. The woman was overjoyed. She was able to wear beautiful dresses she had always dreamed of and her self - esteem soared. She went on to live a much happier life.
Definitely not. Given the rather unusual and potentially suggestive nature of the 'breast expansion' part in 'ahri breast expansion fanfic', it is not suitable for a general or family - friendly audience. It is more likely targeted at a very specific group of people who are into this kind of very specific and often non - mainstream fan - created content.
