Session of Torture and Humiliation II

So I was searching online to contact this guy who claimed to be sadistic and dominant, and we started talking to see if there was compatibility for a session. I told him I was obsessed with torture, wanting to be forced to strip completely and then be tied up in an X shape, the most exposed and humiliating position for torture. My arms and legs would be stretched out so my torturer could access my nipples and genitals, especially my balls, knowing that would be the most intense pain. I showed him a confidence that I could only have from behind the keyboard. He responded very pleased, saying he was looking for a submissive like me to tie up and torture at his leisure. Having my legs open and arms stretched out was his preferred way to tie someone up. He enjoyed seeing his victims naked and helpless, writhing uselessly trying to protect themselves without any result while the torture and pain continued. The best part was when he started with the victim's balls, his favorite part, and apparently mine too. As he told me these things, I couldn't take the excitement anymore. This was exactly what I was looking for. He started asking me more details about what excited me and my limits.

I imagined what it would be like to reach that moment when I would cross the threshold of real torture, probably when he was torturing my balls. Completely naked and immobile with my arms and legs tightly bound to the corners, desperately pulling on my restraints and screaming in pain without any result. Without thinking much, I accepted his conditions. He also told me that the session would include a lot of verbal humiliation, mockery, and insults, and that he would constantly remind me that I had voluntarily agreed to this. When most of the details were agreed upon, he told me that if I wanted to continue, I had to give him proof that I wouldn't back down, so he asked me to send him the email addresses of my coworkers and some humiliating photos and videos where my face was clearly visible. That way, he would know that I was willing to submit to what we were agreeing on and couldn't change my mind when I was probably less excited. This made my blood run cold. Until now, everything had been just dialogue and fantasy, but if I accepted his request, there would practically be no going back. I quickly reviewed our conversation to see what we had agreed on and started tremb...
