She may have been taken and held against her will, she may have been blackmailed into submission, or she may have been a willing slave to the  power of his mind. It matters not how she reached this point. Whatever the reason that brought her to her knees before him, there is now no escape. She will not be going back to the comfort of her family, to the arms of her boyfriend, or perhaps even to her husband and children. She must now take what comfort she can in serving him, her captor, her blackmailer, her owner, her new Master. Her consent is no longer needed, if indeed it ever was. His needs, his desires are all that matter. She exists now only to satisfy his lusts, to obey without question. She has passed the point of no return.
