Clover nipple clamps are place on her tits to add the pain element to the pleasure she's receiving from her clit and g-stop, and to make matters worse for her nips.
First, though, the Hitachi wand is place against her clit, starting out low, to being her genital stimulation. The wand continues to rise in intensity, pushing her towards her orgasms to come, while the fucking machine begins fucking her, first a slow fuck, and then speeding up to a speedier fucking, as the slave deserves.
The wrist and ankle cuffs are locked in place, sealing her to her submissive position above the fucking machine, her cunt inviting the dildo inside, as she waits for the machine to be turned on.
Eventually she is let free of her bandage and able to freely ride the Sybian, giving full gyrations as she receives the pleasure from the powerful machine.
