Though I have no prior experience with BDSM literature, I enjoyed both the BDSM and incestual aspects of the story. It did seem to be a tad repetitive, although I have no way of knowing whether or not this is characteristic of the genre as a whole. It would seem inherent that shorter erotic stories would only have room to focus on the erotica aspect, but I cannot say so with certainty. Regardless, given the constraints of the specificity of the plot, I would say that the character development was good enough to keep it interesting throughout. Overall, the merits of the story far outweigh its shortcomings and I would recommend giving it a read.
