One possible plot could be that Jasper and Bella face many challenges in raising their baby in a world full of supernatural elements. Their baby might inherit unique powers from both of them, and they have to protect the baby from those who might want to use its powers for their own gain.
Bella would be extremely loving and nurturing. She would spend a great deal of time just holding the baby, looking into its eyes, and talking softly to it. Jasper, on the other hand, would be very protective. He would use his ability to sense and manipulate emotions to keep the baby calm and happy.
One interesting plot could be their journey to understand each other's pasts. Since they are mates, they might have to deal with the traumas and experiences that each has had before coming together. For example, Jasper's military past might be a point of contention or a source of strength in their relationship. Another plot could be them facing challenges from the vampire community. Maybe some vampires don't approve of their union, which would lead to a series of events where they have to prove their love and loyalty to each other.
There's also 'Jasper's Redemption in Bella's World'. This fanfic delves deep into Jasper's past and how Bella helps him come to terms with it.

One aspect of 'bella and jasper possessive fanfiction' could be the power dynamics. If one is more possessive, it might imply a certain power imbalance in the relationship, at least in the emotional sense. For instance, if Bella is overly possessive of Jasper, it could limit his freedom in some ways. However, it can also be seen as a sign of their deep connection, where they don't want to lose each other.
Alice could be a great addition. She could be Bella's best friend who is always trying to play matchmaker between Bella and Jasper. She has this uncanny ability to sense when things are going well or not so well between them and gives her two cents whether they want it or not.
In the fanfiction, perhaps the baby's birth is a very difficult and dangerous process. Since both Bella and Damon are from different fictional universes with their own set of rules regarding vampires and such. The baby could be a symbol of a new beginning for their relationship, forcing them to put aside their differences and work together to protect their child. They may have to face challenges from both the vampire and human communities who are either afraid of or envious of the baby.
One possible reason could be that Bella discovers a different side of Jasper that she finds more appealing. Maybe Jasper shows a deeper understanding of her in some aspects that Edward lacks. For example, Jasper's past experiences might make him more empathetic towards Bella's own struggles in a way that Edward, with his own set of vampire characteristics, doesn't quite get.
Their shared experiences also contribute to the soulmate idea. For instance, they both have to deal with the supernatural world around them. This common ground makes them understand each other on a deeper level, which is frequently explored in fanfictions.
