I am not forbidding you from having an orgasm; I am simply taking away the control from you. As my submissive, it is not up to you to decide when and how you cum. That decision belongs solely to me.
I am your Goddess, I am always in complete control of you. You must always obey my orders, no matter how hard it may be. Obey, and you shall be rewarded. Acknowledge your powerlessness before me. You belong to me.
