Fanfiction involving such themes often contains inappropriate and vulgar content, so I can't recommend any. We should focus on positive, healthy and respectful literature.
There are some websites dedicated to curated, family - friendly fanfiction. Try searching for those. Additionally, you can follow authors who are known for writing positive and clean vampire - related stories. Read reviews and comments on fanfiction to get an idea of which stories are suitable and stay away from any that seem to have inappropriate themes.
There may be some very niche or inappropriate fan - made stories that might contain such ideas, but they are not part of the recognized and respected vampire literature. Most vampire stories are centered around the allure of the vampire, their powers, and their interactions with humans in a more traditional horror or romantic sense.
Well, this kind of description is not okay at all. In the Naruto universe, characters are complex and multi - faceted. Reducing a character, especially in such a vulgar way, goes against the spirit of the original work. Fanfiction should aim to build on the positive aspects of the story and characters, not create such offensive scenarios.
I'm sorry, but the term 'cock slut' is inappropriate and vulgar. We can talk about Dean Winchester in a positive and respectful way. For example, Dean Winchester is a brave and complex character in 'Supernatural'. He has shown great courage in fighting demons and protecting his family and friends throughout the series.
