Even if Ray has never had an homosexual experience, he has no problem to admit that he is attracted by Miki, maybe helped by the fact that the man is really handsome and almost without gender. But when it arrives to sex, Miki is not female at all, and Ray has to arrive to pact with his inner side, not only to surrender to a man, but also to surrender the upper hand in the sexual relationship.
I don't know if Barbara Sheridan is planning something else for these two characters, but it seems to me that Ray's step toward the dark side it would not possible or right only for a week-end fling. For Ray is more difficult to accept the type of D/s relationship that Miki is offering, than to accept to have sex with another man; and it's not strange this approach, since having sex with a man could be a passing thing, above all since Miki is so beautiful that is over the boundaries of sex, but entering the BDSM world is not something to take with lightness.
Anyway the story is not so long, 44 pages, and so it's possible that this is only prologue of a longer story.
