I'm turned on by the possibility of this as well , perhaps we can implement some incest and some interracial cuckolding? All types of deprived kinky things waspy socialites like to keep hush hush. A husband and wife on camera snowballing a generous donation from a young black gentleman. Hubby watching his son and his son's black friend go to town on his wife then clean up the mess afterwords. Career suicide. Especially the more humiliating and taboo the kinks are. BDSM, cross-dressing, gangbangs, incest, bestiality, etc etc Maybe the originals tapes are somewhat tame at first just vanilla stuff, but the blackmailer could force the couple to engage in more depraved sexual acts over time, producing more tapes to blackmail them with, if they don't want the originals to leak and it becomes a thing he uses to control them with.
