Perhaps there is a fellow slave or a sympathetic free person in the novel. This character could play an important role in the slave girl's journey, either by providing support, friendship, or a different perspective on her situation.
Well, of course, there is the slave boy himself. He is usually the protagonist, often depicted as brave and resourceful despite his difficult circumstances. Then there are the slave owners, who are generally the antagonists, cruel and greedy, representing the oppressive system. There may also be other slaves, some of whom could be friends or mentors to the slave boy, teaching him survival skills or giving him hope.

The main character would be the boy who has to endure this subservient cuckold slave position. He is the focus as we see his struggle and his life in this difficult situation. The other two main characters would be the two people in the relationship that he serves. They could be of different personalities. Maybe the man is more cruel and demanding, while the woman is more manipulative, using her charm to keep the boy in his place while she enjoys her relationship with the man and the power she has over the boy.
In this kind of story, the main characters could be diverse. There could be the freed slave, who is likely strong - willed and determined to make a new life. Then there might be a guide or companion who says 'I will go with you'. This companion could be an abolitionist, someone who has fought for the freedom of slaves and is now helping the freed slave navigate the new world. There could also be other characters they meet along the way, like kind - hearted strangers or former slaves who have already established themselves and offer advice or assistance.
Typically, you'll see the main characters from the original High School DxD series like Issei Hyoudou. He might be in a different role in the fanfic, perhaps more involved in the'slave' aspects of the story.

They might be forced to do things against their will but still have their own moral compass that they try to follow.
