Natali Demore & India Summer

Black Diamond now has both Wunder Women tied spread eagle and connected to a "pain and pleasure" machine. Whenever Wunder Woman cums from the butterfly vibe attached to her clit, Wunder Girl gets an electric shock. She leaves them like this for a while, then comes back and ties them facing each other and forces them to kiss and then clamps their nipples. She delights in making the two sisters make out. Then she makes them eat each other for the grand finale!
