I'm married and in a vanilla relationship. I have had encounters with "professionals" over the year. Those experiences are rather rare so I often spend time lurking on FetLife. I happened to strike up a friendship with Cheryl, Mistress Demanding. We have had a few encounters when my wife is out of town, this was a time that I will always remember. Cheryl, and I had planned a day together. My wife was out of town so I was hoping for something special. I knew not to ask what her plans were but she knows all of my secrets. When we met up, I was wearing lingerie under my clothes as she had asked. She asked for a quick "fashion show" and the announced we were off for some shopping and dinner. She took me to an "adult" toy and fashion store. She asked one of the clerks for help picking some lingerie and a couple of very slutty dresses. She and the clerk had me try them on and "model" them. Before she would let me back in my street clothes, she fitted a CB-6000 on me and had had me show that to the clerk. Once back in my street clothes, I paid for the purchases and we headed off to dinner. Once back at her place, she had me change into one of my new outfits and prepare for the night. At about 8 or 8:30 several of her friends arrived, some Dommes and some subs. The night progressed and I found myself sucking cock for the first time, actually several cocks by the time the evening ended. I'm very much into humiliation and forced bi as fantasy material. I had shared these fantasies with Cheryl but had never had the courage to try and fulfill either the shopping/public display or the cock sucking. After all had left, Cheryl held me and asked how I felt. I was a bundle of emotions and just buried my face into her breast. She whispered to me that she felt it was time for her to take me "the rest of the way". Cheryl is a treasured friend and I'm oh so grateful for the gift of that day.
