This is an interesting story, with an unusual premise for erotica. The writer has woven the story well, with a number of loose threads that he can easily pick up later. He has even hinted at a future digression from the story, as well as almost promising another with the current central characters. The story is clear and grammatically correct, ensuring that the reader is not distracted by trivia.
The plot is not your standard fare, even for the BDSM sub-culture. Cuckoldry is generally not well handled in the literature: most often it is the big black guy turning the white couple into twittering fools. In this story we don't even know the race of the two men: it is irrelevant. Nor is anyone played as a fool. These are people exploring a new frontier, and feeling their way along as they go. The emotion is raw and sharp as the exploration of dominance and submission is played out.
It is a shame that it is so short. That is my only technical complaint. With the situation handled as well as it is in the story, Joe should have strung us along further. Joe should definitely expand this into a series.
As a stroke story: way up there if dominance is your kink (possibly if submission is your kink too!). I liked it hugely, and will look up more of Joe's stories.
