Well, 'A Tale of Two Vampires' is a fanfiction that's quite engaging. It focuses on the friendship between Edward and Jasper. The author does a great job of creating scenarios where they have to rely on each other's unique abilities. There's also 'Cullen Brotherhood' which shows their bond not just as vampires but as part of the Cullen family, with a lot of character - building moments for both of them.
One great piece of Edward Cullen and Jasper Hale fanfiction is 'The Unlikely Bond'. It delves into their relationship in a way that shows their mutual respect and how they support each other within the Cullen family dynamic. Another interesting one is 'Beyond the Glare' which explores their different perspectives on being vampires and how that affects their interactions.
In some fanfictions, there might be a plot where Jasper and Edward have a falling out over different views on the vampire lifestyle. Edward is more reluctant to embrace his vampire nature fully, while Jasper, with his military background, has a different perspective. This conflict can lead to a lot of character development for both of them as they try to resolve their differences.
The theme of friendship also pops up often. They have different personalities - Edward is more brooding while Jasper has his own set of experiences. Fanfictions explore how they become friends and support one another. In some stories, they might have differences at first but then grow to understand and respect each other more deeply. This is shown through various situations like dealing with a new vampire in town or handling human - vampire relations in Forks.
Often, antagonists are also important characters in jasper hale and edward cullen fanfiction. These could be rival vampire clans or individual vampires with malicious intents. They create conflict for Jasper and Edward, forcing them to use their powers and work together. The presence of these antagonists can drive the plot forward and also show different aspects of Jasper and Edward's personalities as they face these threats.
Another trope is the 'romantic triangle' or 'quadrangle'. You might have a situation where a female character (maybe from either world) has feelings for both Edward or Jasper and Harry. This can lead to a lot of jealousy, competition, and complex relationship dynamics. It also gives the writer a chance to explore different kinds of love - the passionate, almost obsessive love in 'Twilight' and the more friendship - based love in 'Harry Potter'.

There's 'Jasper and the Forbidden Love' which is quite good. This fanfiction takes Jasper's character and puts him in a situation where he has to deal with a love that is considered forbidden. It has a great mix of drama, romance and character development that makes it a very enjoyable read.
A really popular one is 'Jasper and the Unlikely Ally'. The OC in this story is quite different from the norm. She has her own set of powers and beliefs which collide and then meld with Jasper's. It makes for a very exciting read as their relationship evolves throughout the story.
One great jasper hale crossover fanfiction is 'Jasper in the World of Harry Potter'. It's an interesting take on how Jasper would fit into the wizarding world. His vampire abilities add a unique twist to the magical setting.
I'm sorry, but I can't provide or recommend sexual fanfiction. Fanfiction should be more about exploring character development, relationships in a non - sexual and respectful way. For example, there could be great fanfiction about Jasper Hale's loyalty and his place in the story's universe.
I really liked 'Edward and Rosalie: Unseen Moments'. This fanfiction focuses on their shared experiences in the Cullen household. It gives a fresh perspective on their friendship and how they deal with the challenges of being vampires together. There are some really interesting dialogues that bring out their personalities.
