It was Friday evening, my wife was out with her friends so it meant the whole evening chatting to my Mistress and maybe Master Colin will also be about for a chat. I logged on and found a message from Mistress informing me that she was already in a chat room with Master and for me to come and join them, this was unusual as we normally shared a private room just the two of us and then opened a second if we wanted quests, recently it had always been just Colin, well not really recent as he has had our undivided attention for the last year or more. The message was simple and to the point, Room name:- Mistress Jane, password:- Bull, attend immediately, Mistress. I logged into the room... Evening slave about time we have been waiting for you.... ........Sorry Mistress only just logged in. Mistress told me she had some exciting news, Master has created a picture album just for slave, he will send the link, look now and tell us what you think. I went back to the messages and sure enough found the invite to view private album " For Sissy", not a great start i hate that term, but clicked on the link to open up the pictures......... Its difficult to describe how i felt, i went into a cold sweat, my ears rang it was total shock, there before me were pictures of Mr Gregor's cock, not only slack like I had seen it before, but now fully erect and looking amazing and honestly scary in its size and firmness. The back ground was around the pool area where only a few hours I had stood intimidated by him and trying to hide my small flaccid cock from his gaze. As the shock wore off i realised i had been set up by my Mistress and Master, Mistress had sent me to check out Master Colin, but what for, did she intend to meet him? I went back to the private room, tried to stay calm and casual and just said thank you Master, you have a magnificent cock...... Almost I immediately i got a PM from Mistress asking 'well slave what was he like, did you have a good feeling, what are your thoughts on taking this to the next step? It may seem strange dear reader but we both agreed many years ago that we both had to agree and make sure it was 100% safe for both of us, before we met somebody else, Mistress had never been this keen before and you must appreciate we did have a bad meet at the start of our relationship as Mistress and slave. I told her on meeting him I immediately felt he was the Alpha male and without realising it i acted submissively in his company. He was kind and as he had chatted to us for over a year not pushy. She then shocked me by saying, he is the one, I want to take this further, I need to submit to him, I have felt like this for weeks. I replied calmly, OK Mistress, I'm yours to use for your pleasure if that includes a third person i can not argue or refuse you. We both turned our attention back to Master Colin, soon to be our Bull.........
