Bianca is an insulate submissive and Francesca has to punish her to set an example to the other subs. First Bianca is given a spanking. Francesca then puts heavy metal balls into Bianca's ass, but her asshole is so tight it breaks the strap connecting the balls and Francesca must go in with her fist to get them out. Bianca is fucked hard with a giant strap-on before she's taken to clean her ass up with an explosive enema.
