It?s the final stage of accepting your humiliating degrading reality: I want you to abandon sex with anyone but your hand forever. You no longer need to participate in intercourse with other humans (even if you could), because your life will now be spent in abject stroking. You will commit to a lifetime of masturbation at my command, wasting every last moment of valuable human interaction with meaningless jerking. You have nothing left, you've already arrived here. Now it's just time to acknowledge it.
