Fauxcest is the most commonly used term to define the practice of acting as and addressing one's partner during a scene as if they were a family member - "Dad"; "Mom"; "Big brother" - during sex (predominantly BDSM, as it most often accompanies various flavours of CNC). It's way more common than one may think.
