I agree that humiliation strips the inhibitions away and forces you to focus on pleasing your DOM/bulls.
My current DOM is 24 y/o, much younger than me and my husband. He is the cousin of my previous DOM who moved away from our area but gave me to his cousin. I was told by the new DOM that I needed to obey and be acceptable to his crew or he was not interested. My first meeting with his crew set the expectations.
My husband and I were told to show up at an apartment in a part of Detroit that we had never been to, knock on the door and both be naked when the door opened up. Although I was told to wear 5 inch heels, my husband had to be completely naked. This meant that we were stripping in the hallway of the building with total strangers watching us undress. When we were undressed, we knocked and were allowed into a room of about 10 young bulls. We were led into the room and my DOM told me to introduce ourselves to the group by telling our personal and work background and then to discuss our commitment to serving the black man. I had been black only for some time, so I had to explain when and how I had given up whitebois. While I was explaining our background, my husband was told to stand next to me and play with his dick. He was so intimidated by what was happening, he shriveled up despite his constant jerking off.
When I finished, we had leashes attached to us and were led around to be sampled by the bulls. 30 minutes after entering the room I was on my knees sucking the dicks of 20 y/o bulls being called all types of names including grannyslut, whore, white trash.
The whole experience was totally humiliating for both me and my husband. But for the next week or so, I was so turned on that I craved more bbc with a yearning that I was calling my new DOM and begging him to fuck me. He wouldn't see me for 4 days and when he did see me we had incredible sex. I have been totally devoted to him since then. Even though he is young, he is an incredible DOM and and awesome bull.
There have been many other humiliating moments but this one is my most memorable one.
