Very erotic. Not entirely sure who the good guys are yet, the Lady riding the machine was after all trying to commit arson. I liked the machine parts obviously, the detail of materials and turn of the last century terms showing considerable research of the era, or perhaps such details overlap with the author's interests in steam trains and old machines in general, of which I have in common by the way. In either event I like the repurposing of the technology of the day for such nefarious and entertaining purposes, you should definitely write more.
Thanks for sharing, Jackie.
