At first, Kagome is likely to be angry. She's a strong - willed character, so being kidnapped goes against her nature. She would probably struggle and try to escape immediately, yelling at Koga about how wrong his actions are.
Another theme is adventure. Given that they are both part of a world full of demons and magic, fanfictions often send them on exciting quests together. For example, they might go on a journey to find a powerful artifact or to defeat a new evil that has emerged. This not only tests their relationship but also shows their individual strengths.
Perhaps in the fanfiction, Koga kidnaps Kagome believing she has some special power that can help his wolf demon tribe. He might think that she can heal the sick among them or bring good fortune to their land. However, Kagome doesn't actually have this power, and she has to convince Koga to let her go while also trying not to anger him too much. As she's held captive, she might learn more about the wolf demons and their way of life, which could be an interesting aspect of the story.
Inuyasha would most likely be the first one to try and help Kagome. He has a strong bond with her and would not stand by while she's in danger. Sango and Miroku would also probably join in the rescue. Sango with her skills in combat using the Hiraikotsu, and Miroku with his spiritual powers. They are Kagome's friends and would feel obligated to help her.
One common plot twist could be that Koga actually kidnapped Kagome to protect her from a greater threat. Maybe there's a powerful demon that's after Kagome, and Koga, despite his rough ways, believes he can keep her safe. Another twist might be that Kagome discovers she has some hidden power while in Koga's captivity that helps her either escape or gain an understanding of the demon world in a new way.
There are many fanfiction stories out there involving Koga and Kagome. To find the popular 'lemon' ones, you might want to look at the number of reviews and favorites a story has on a fanfiction site. If a story has a high number of both, it could be an indication that it's popular. Also, consider following some well - known fanfiction authors in the Inuyasha fandom as they may write such stories. But always be cautious as the 'lemon' aspect might involve adult - themed content.
I also like 'Kagome and Koga: The Unlikely Bond'. This fanfiction is quite long but it's really worth reading. It starts with Kagome and Koga being forced to work together due to some circumstances. As they spend more time together, they start to understand each other better. The author creates a very believable development of their relationship, from initial distrust to a deep and meaningful bond. There are many twists and turns in the story that keep you hooked until the very end.
In this fanfiction, perhaps Kagome is tired of the on - again - off - again relationship with Inuyasha. When she meets Koga, she is attracted to his straightforwardness. Koga, for his part, has always had a thing for Kagome. They start to travel together, and Koga shows Kagome the beauty of the wolf demon world. Kagome, being curious and open - minded, enjoys learning about it. Along the way, they have deep conversations about their hopes and dreams. These interactions would slowly build the foundation for their love.
When writing 'koga kagome lemon fanfiction', it's crucial to immerse yourself in the world of Inuyasha. Familiarize yourself with the settings, the other characters around Koga and Kagome, and the overall mythology of the series. For the 'lemon' part, it should serve a purpose in the story, like enhancing the relationship between the two characters. Write in a way that shows your passion for the characters and the story. Use dialogue effectively to bring out their personalities. And always proofread your work to make sure it flows well and is free of errors.
