Mistress Nikki, looking stunning in her leather boots and harness, approaches her underground cell, unlocking the outer metal gate and revealing the locked pit and her slave waiting at her mercy. She uses her sharp heels to get his attention, treading on his hardness and then cruelly whacking his balls, before releasing and locking him to the steel gate. He is now vulnerable to her CBT machinations, a steel clamp used as a cock ring and an intense large sounding session stretching him, his big dick staying hard at the attention it is receiving, even ejaculating while the steel rod is filling him up, such is Nikkis total control.
