Well, without reading the 'booker cums inside elizabet fanfic', we can only guess. Maybe it's a fan - created story that takes elements from a source material (if there is one) and expands on the relationship between Booker and Elizabeth. It could be a romantic, action - filled, or even a dark and mysterious story depending on the author's intention.
Fanfics should generally adhere to certain ethical and moral standards. This kind of explicit sexual content violates those standards and can make many readers uncomfortable. It also goes against the family - friendly and positive values that most fan communities aim to uphold.
There should not be any fanfic with such inappropriate content in a family - friendly context. Fanfictions are supposed to be creative works within the boundaries of good taste and propriety.
In reality, pregnancy risk isn't just about who cums first. It depends on various factors like the timing of ovulation, the presence of sperm in the reproductive tract, and overall fertility. So, focusing on who cums first is not a reliable way to assess pregnancy risk.
I'm not entirely sure what this specific phrase means as it seems rather unclear and ungrammatical. It could potentially be a very creative or misphrased description, but without more context it's difficult to say.
Fanfiction should focus on positive, healthy and creative storylines rather than such inappropriate scenarios. We should look for fanfictions that are in line with moral and ethical standards.
