Undiscerned Lover

Karen is stuck inside fantasizing about horses. Or... not horses, but horse-like creatures... maybe centaurs? Anyway, she's thinking about a very specific horse part that she feels she shouldn't be, then she falls asleep. When she wakes up, she's not in her room, can't see, can't hear, but can smell, taste, and feel. And the thing she feels in the darkness might be the very thing she wants most.
