I have been in chastity for about 2 months now. This is about the longest I have ever been. I met my GF some time ago and when I opened up about the lifestyle, she was totally new to all of this and very vanilla. At first, she was just holding my keys to accommodate me and basically let me out whenever I asked. We talked a lot about all of this and my fantasies but it seemed, she just wasn't into it that much. I was gratefull for what I got and was about to give up on the thought of her really being dominant and testing my limits. Recently, she started "experimenting" more though. She did not let me out when I asked. Before her change, she made it clear, that whenever I please her, she would also please me to give back. I did not get to orgasm every time, but she'd always tease and play with me. This also stopped. Now I find myself licking her or watching her use her womanizer more often and my cock doesn't get to see daylight that often. Her everyday behaviour has changed too. She usually did much of the housework (she is only working parttime, so she is home more often than me), now she plays her games and let me do the work. Instead of asking if I could do things for her, she tells me to do them. I am totally fine with all these changes, could not be happier When I asked her during one of our last sessions about when I would be allowed to cum, she told me that it was up to me. She said I could cum as soon as I bring her proof that I sucked another mans cock. I was really dumbfounded at this and I told her so and that she must be joking. She said that this was one of the fantasies I once told her about (which is true) and that she wants it to become reality. I told her there are the fantasies you want to come true and the other ones, that are fine in your head but not otherwise. She said that if this was a hard limit, it'd be fine, she'd unlock me but then chastity play would be over. She said everything until now was living out my fantasies and her getting herself into the mindset to be my dream-Dom. She felt like a "service-Dom" for me. Now this is a fantasy of her own, she really likes the thought and finds it hot and wants me to do that. She told me to take my time to think about it and tell me about my decision. I am really unsure how to handle that. The thought of sucking another man really scares me. But on the other hand, she has a point and since it is a fantasy of mine, I might even go through with it. But how? I can't go to a gay bar and tell some of the guys I want to suck them and I need an image to proof it for my Mistress? I told her about that and she said, that this would be my problem alone. She does not want to take part in this, she just wants to have the proof and all the details afterwards. At least for this time *gulp* Any advice how to approach this? Should I reject it and hope she will still continue our chastity play? Or go through with it? How do you do that? How do you find someone for that and keep it anonymous?
