This story is a blend of Steampunk and Erotica. There are four chapters and I will try to load it as a single story. It is a Victorian Era Steampunk story which is typical and the time travel is back to the Early Roman Empire to participate in an orgy of perverted pleasure.
It starts simply enough, with an online personal ad, and a decision to suspend disbelief. Miranda plays along with the hypnosis fantasy, knowing that she can always pull back if it goes too far. It does. She doesn't.
