The relationship would likely become more intense. They would have to rely on each other more, and their bond would deepen as they are about to become parents. Inuyasha would probably become more protective of Kagome.
Kagome would probably be shocked at first. Then she would start yelling at Inuyasha, demanding to know why he's doing this. She's not the type to just sit there and take it.
Another fanfiction concept could be set in an alternate universe where they are all students in a school. Inuyasha might be the troublemaker, Kagome the studious one, and Sesshomaru the aloof and brilliant student. There could be a mystery at the school that they have to solve together, and through this, they form an unlikely friendship.
Sesshomaru is an enigma. In fanfiction, his cold exterior and his pride as a full - demon are prominent. He initially sees Inuyasha as a weak half - breed, but as the story progresses, he may come to respect Inuyasha's growth. His relationship with Kagome can also be an interesting aspect. Sometimes he's indifferent to her, but other times he might be intrigued by her powers and her ability to change Inuyasha.
In fanfiction, the relationships between Inuyasha, Sesshomaru and Kagome can be very diverse. Some fanfictions might focus on Inuyasha and Kagome's relationship, which is often a complex mix of love and adventure in the original series. Their relationship is full of bickering and mutual understanding. While Sesshomaru, being Inuyasha's brother, may be depicted in fanfiction as having a more aloof or even begrudging respect for Kagome. He might interact with her in unexpected ways, perhaps even having a slow - building friendship or an unusual alliance.
No. Fanfiction that involves sexual content about fictional characters is not appropriate. These characters are often part of stories that are aimed at a wide range of audiences, including younger viewers. Writing such fanfiction goes against the spirit of the original work and can also be considered disrespectful to the creators and the fans who enjoy the story in a more positive and family - friendly way.
There might be some 'Inuyasha abuses Kagome' fanfiction, but it's not something that is likely to be promoted or widespread. The original story is about their relationship growing and developing in a positive way, so this kind of negative and abusive take goes against the spirit of the original. However, in the vast world of fanfiction, it's hard to say for sure that none exists.
