tag sisterly cuckold
Tag description Sister NTR scenarios centering on the sibling dynamic being corrupted. Sister as the NTR subject, she's seduced/taken by the brother's rival, bully, or friend, with the humiliation focused on the brother losing his protective "big brother" status (or losing his innocent "little sister" image).
note Since I believe "motherly cuckold" should be a tag, I also think that "sisterly cuckold" works well too since it's the other closest female family member, and it's a theme that can be often found.
