It could develop in a complex way. The spanking incident might initially create tension between them. Harry could be angry or resentful towards Sirius at first.
One possible scenario could be that Sirius Black spanks Harry as a form of discipline for some dangerous or disobedient behavior that Harry has engaged in within the context of the fanfiction's plot.
Yes, there might be some fanfiction with this theme that is written in a non - offensive and family - friendly way. It could focus on Sirius Black disciplining Harry Potter in a more light - hearted or mentoring - type of situation rather than anything inappropriate.

Fanfiction about these three can take many forms. For example, there could be time - travel fics where Harry goes back in time and meets Regulus and Sirius when they were younger. This could lead to all sorts of interesting plot twists, like Harry trying to prevent Regulus from joining the Death Eaters in the first place. Or it could be a fic where Sirius survives and he and Harry explore the secrets of the Black family together, including things that Regulus left behind. There are also fics that focus on the emotional bonds between the characters, showing how the different personalities of Regulus, Sirius, and Harry interact and influence each other.
