My exMaster used CR for punishment and for play. When using it with play it was such a tease and it would get me all anxious and keep me in that state of mind that he wanted, but I always knew with play he would be ordering me to cum sooner or later. Even though once and a while he would end the night with me not being allowed to cum, which would frustrate me to no end, but he always made me much happier in the morning. He also liked to have me masturbate without cumming before we would see each other, it did make it much more intense when we would see each other. For punishment, ugh, it served its purpose as punishment. Anytime I was punished, when the punishment was over it was always such an emotional relief, if CR was part of the punishment I could be crying my eyes out but when he told me to cum it was like a rush of bliss. As soon as it would be over his attitude would switch a little and we would both be out of the mind set that I was being punished, well obviously since the punishment was over, but it was kind of like him letting me cum was the end of that punishment and everything would be fine as long as we both learned a little and got something out of it. For me CR was both fun and punishment, depending on the situation, but I never got the situations confused and no matter what it was used for it got the correct message/attitude across, for him and I.
