the submissive in the story will NEVER achieve orgasm within the story. they can get very close, and they can beg to cum, but at no point will the dominant or dominants ever permit it, nor will an accidental orgasm occur against the dom's permission. at some point within the story, the submissive will agree, either verbally or in writing, to never orgasm again. the story will occasionally mention that the sex is not about the pleasure of the submissive, that being kept on the edge feels better to the submissive than cumming ever could, and other various pontifications about the permanent denial of the submissive.
