Why this scenario works
Regal
In this scenario, Seraphine wants to maintain a regal, controlled power : unshakable and intoxicating while Corin is focused on show unwavering obedience and desire for her approval. That pull in opposite directions is what drives the scene. Power expressed through formality and status has its own charge. These scenarios work because the dynamic is clear and theatrical, which makes it easier to commit to without self-consciousness. The more fully you play the role, the better it works.
Good for couples who enjoy theater and like playing larger-than-life versions of a dynamic. The formality of the setting makes it easier to stay in character, and the hierarchy is explicit enough that neither person has to guess where they stand.
