Orgasm control is a hard thing to do well, as a Dom I have forced sub/slaves to climax without giving permission. When morgan was pushed to far, even though she begged and begged for permission then cried for quite a while afterwards I refused to punish her. The truth be told it should have been me that was punished for doing that to her.
She knows that she must beg sincerely to be allow to climax and I know when she can't hold it back any more.
