Welcome back. Not really surprised to see you here, considering how the last session went. I don't think you really grasp the seriousness of what we're trying to do here. You are suppose to experience absolutely no pleasure when ejaculating. Do you understand? Now undress yourself and get into proper worshipping position. This is just the way it has to be. Now slowly start to stroke, listen to my instructions. Loosen your body, relax. Tension only brings more potential for pleasure. You will cum when I say to cum. Say, "yes, mistress". Good boy.
