Activate her shocking clitoral augment.

Even as her body shakes with her orgasm she looks up at you in terror. As your former Spymistress she has witnessed you punishing many unruly slave girls. As a matter of fact, she used to revel in it! Now she will receive a similar punishment. You pull the loose end of the belt and tug her tits higher. She arches painfully on her knees in the spreader bar.

"Noooooooooo!" she cries as she anticipates the shocks within her clitoral augment.

sssssssiiiiiiiiiiiizzzzZZzzZZLLLLLLLLLLLE... CRACK!

She yelps high on her knees as the punishment shock fires off within her bud. You pull the belt tighter around her tits and slowly thrust your massive shaft between her snuggly wrapped tits. You lean in and study her face. She looks up at you with big pleading eyes.
