I spent the weekend as I normally do, serving my Master. On Saturday night I told my Master that if he wanted to he could call me by his ex-roommate's name. I really liked her when they were living together and I could tell that even though he said he wasn't interested in her he still would have slept with her. At some point I developed a little crush on her, too. Anyway, Master likes to degrade me and I thought he would enjoy calling me by her name for its degradation and newness. I told him that I wouldn't be mad at him for it later (it was my suggestion, how could I be mad?) and we went through with it. We both really enjoyed doing it so we tried it again Sunday night. The scenario changed a little. This time he told me to imagine being all tied up and being forced to watch him be with her, to taste her on him, things lake that. I broke down and started sobbing because it hurt me to think of it. I told Master that I would feel like I was being punished and Master told me he would only do that if I had been really bad. The biggest issue I have with the whole scenario is seeing my Master with another woman that is not a slave. It would be hard enough seeing him with another woman, but I really don't know if I could take it if he let her have control of me or, even worse, if she were his Mistress. Has anyone done this in real life? Please, PM me if the details are too much for the forum. My Master would like to talk to me more about having another person with us but I need to hear from people that have done it already: did feelings get hurt? Would you do it again? What were the roles of the people involved? What would you have done to improve the experience?
