Hi, I'd like to start by saying that I've already read the newcomers faq. So let me start by describing the situation. The girl that is acting as my sub (and introduced me to this) is an old friend/former girlfriend. However she is already in a relationship with a dom. The playing we do is only through conversation/im and fantasizing. Furthermore her partner isn't aware of the fantasizing we're doing. However we are moving to a point we're we'd like to bring at least some of the play into the real world, which brings me to my question. Does anyone have any suggestions for punishments I could order her to administer either over the phone or through the screen that will inflict pain or humiliation, but won't leave marks or be noticed by her partner? We've had some discussion on our limits and desires so anything suggested is helpful, I just won't use those that we find to be inappropriate for us. Almost forgot, any help is much appreciated, thank you!
