There's a fluidity that carries the reader along as if swept on a torrent
"She leads me to an altar, I succumb
I give myself to her, to her caress
Though trepidation fills my mind, my loins

Then softly (yet enthused) at her behest
I give her what it is she seeks from me"

It's a terrific snapshot of that curious amalgam of excitement and dread which attends a taboo tryst and many readers will need to take a personal break after reading.
