Master Frederick binds Harlye Synn's breasts and attaches TENS unit electrodes to them, as well as inserting an electrode into her pussy, He then turns the device on and gives her continuous waves of sensation, shocking her tits and pussy. He then fucks her with a vibrator... And then fucks her mouth with his big, thick cock. 

Next he fixes a neck strap around her throat and ties the rope to a ring in the wall so he can hang her as he fucks her, by pulling her down the bed. Harlye Synn does something even hotter than that: She grabs the rope herself, and pulls it hard while Master Frederick pounds her deep!
