For only the second  time on here I have found a Mistress  K (not completing her name to protect her privacy)who is willing to chat and offer great advice and not a Manhater.
Perhaps the most despicable profile fitting into that category is "Dinglebury"BEWARE chaps!!!! or maybe you've been snared by her/him  already.
Very aware about supposed male slaves who are offering their services to find out that all they really want is a freepassage to  my sub,

 This from the diary of my sub Marie.

Today was my busiest yet, sex-wise. I saw three clients, all of them kinky and fun. Firstly I joined a pro Mistress as her female submissive as she dealt with a male client.  

I arrived early and went down the stairs to her Baker Street apartment. This was luxurious and set out in various rooms: sitting room, medical room and two dungeons. I changed into a corset, stockings and suspenders as instructed, and joined the mistress in the sitting  room. She was dressed in leather and looked strict and powerful. She dealt with my payment first, giving me an envelope with the money in it.  After that we chatted for a few minutes before her client arrived.  He turned out to be a very pleasant middle aged man who knew the Mistress well and was quite comfortable with her. He was excited at the sight of me and was allowed to kiss me as he lay on the seat with raised legs in the medical room. Here Mistress  told me to pinch his nipples as she inserted a rubber tube into his anus and pumped him full of water. After about five minutes he was sent to use the toilet and returned clean and ready for the anal torture she had planned for him. Now we moved into the dungeon. It was very well equipped, with whips, canes, ropes and chains hanging all around the walls.

The mistress lay me face-down on a bench so that my bottom was exposed, which excited her client. She selected a thin stick and caned me lightly. Then she turned me over and ordered her client to climb on top of me and fuck me, which he did. He was then asked to climb off and lie on the bench. I had to pinch hard at his nipples as the mistress put on a rubber glove and began inserting fingers into his anus. This was something he obviously enjoyed as he began to groan with pleasure. I bit his nipples, producing further groans. Gradually  Mistress inserted her whole hand into his anus and moved it around, causing him to scream with pleasure. I crawled under the bench and sucked at his penis and balls which were hanging down through a hole.  This caused cries and an eruption of sperm, which I drank dutifully.

After he left, Mistress and I sat  and had a cup of tea. She was pleased with the meeting and told me that her client had told her he wanted me to be there next time he saw her.  We also talked about what else we might do together in the future. All in all it went well, and I look forward to seeing her again.
