Well, these comics might combine the allure of the little black dress with the fantasy of furry characters to create a unique and sometimes risqu茅 visual experience. They might have detailed art and imaginative scenarios.
The relationship might face some rough patches too. They could argue about things like where to live, how to raise the baby, etc. However, through these arguments, they learn more about each other and eventually find solutions that work for both of them, which in turn, deepens their relationship in the long run.
Such pornographic comics are not something that should be pursued or explored. They often violate moral and legal norms and can have negative impacts on individuals and society.
Puck would probably start to show his softer side. Normally he's tough and a bit rough around the edges, but a baby would make him more empathetic. He'd learn to communicate better, especially with Rachel, as they navigate this new phase of their lives. Rachel would become more nurturing. She has a big heart already, but having a baby would intensify that. She would also become more assertive in making sure Puck is fully involved in the baby's life. She doesn't want to be a single mother, so she'll push Puck to step up and be a good dad. And they would both learn to sacrifice some of their own wants for the sake of their new family.
Honestly, without more context, it's hard to define 'puck fiction' precisely. It could be the work of a particular author or a small group of writers who use the term to describe their fictional works. It might have unique themes, like perhaps dealing with magic and chaos if it's related to the Puck character, or it could be something completely different, such as a new wave of science - fiction stories where 'puck' is a key technological or alien element.
