From speculative fiction author extraordinaire N.K. Jemisin’s website, as part of an ongoing project to make consent sexy again:
Writer Beth Bernobich started this, after hearing complaints that it’s somehow unsexy to seek or confirm consent during sex (or during fictional sex). So far she and Martha Wells have posted examples of sex scenes showing clear consent, so I figured I’d join in. Three posts make a meme, and all that.
This one’s probably familiar to many of you; it’s from The Hundred Thousand Kingdoms. Consent was an ongoing theme of the relationship between Yeine and the god Nahadoth, in part because Nahadoth actually can’t do anything to her without her consent, and in part because Yeine is effectively a master to Nahadoth’s slave and there can be no true consent in such situations. She could command him to do what she wants, although the results would likely be less than optimal. Nahadoth has managed to win a modicum of power for himself despite his enslavement by deliberately twisting the meaning of consent; he entices potential lovers to give him permission or bad commands, and he uses that to kill them. Yeine knows this, but she hopes — she believes, and belief is power when you’re dealing with gods and magic — that he won’t kill her. The consent that needs to be given in this case is multilayered.
The sexy excerpt (NSFW?) is here. Whether either party has established true consent in the excerpt is a question open to debate.
