A fanfic that stands out is 'Pathways of the Heart'. Here, the author beautifully portrays Naruto's more dominant side (seme) and Kakashi's more receptive side (uke). It explores their relationship against the backdrop of the Naruto universe, with all the familiar characters and settings adding depth to the story.
Often, trust is a big theme. Since Akashi has his own issues with control and Kuroko has his own quiet strength, fanfics may focus on how they build trust in a relationship. For example, Akashi might have to learn to let go of some of his controlling tendencies and trust Kuroko. Also, the theme of hidden desires might be present. Given their public personas in the Kuroko no Basket world, the fanfic could explore their private, unspoken desires for each other that they only reveal in the context of their relationship.
One such novel could be 'Guilty Pleasures' by Laurell K. Hamilton. It has elements that might be related. The main character Anita Blake deals with various supernatural beings including vampires, and there are complex relationships which could be seen in the seme - uke dynamic in some ways.
