This is one of these images in which you feel there is an entire story hinted by what is shown. Are the human woman and the demoness captives of someone else brought together to play for their captor's entertainment or has the human woman simply been brought to the boudoir of the demoness for her pleasure. The human woman's expression suggests this is unexpected so how quickly has she ended up here in the nude in a pretty submissive position? Is this a dream that suddenly became real? I am enjoying speculating!
