Giving you a little taste of punishment

You wait in silence for an answer, but don't get one in the form of text. Instead, you feel pressure inside your pussy, causing you to flinch. The pressure increases and you realize that your pussy is being stretched open! You cry out in pain as the walls of your cunt are pushed outwards. The pressure continues for a second before stopping, leaving you frozen in pain. You stay there, looking at your own shocked expression on the screen, until the pressure recedes and your pussy returns to normal. You breath heavily and your vision blurs. That was intense. You don't know if you could go through that again, and they definitely have worse things in store...

The typing resumes. "I assume you now understand your position. I am watching your camera. Follow my instructions. I'll know if you don't." Seeing no other option, you nod. Apparently that's not enough. "Say 'Yes, master.'" You shiver, but are helpless. Your voice is shaky, but you say "Yes... master." The typing prints out a simple "Good girl," before listing instructions.
