Looking for a S/M Title

There was a book I read long ago that I thought was called Lady Elizabeth but I can't locate it. It was a violent and explicit book about a Victorian? woman caught in the Middle East? and made into a slave or part of a harem. I remember one scene where she was on a table, naked, in display in front of an audience and an egg? was put up her anus after an enema?

I read it in the 80s or 90s and it was by "Anonymous" from what I remember.

I think there was a scene where she was caught with her ladies' maid out in the desert by a bunch of bandits and they raped her and/or sold her to the master/mistress above.

The audience might have been a bunch of English nobs, but it was in a desert type environment.

This could be one of barbara cartland's ? she used to write about steamy stuff but also throw in domestic tips.
hollis.

Sounds like The Lustful Turk.

No, it's not The Lustful Turk. The language is much more modern.

Nor is it Cartlard. I doubt she would have written something XXX-rated.

It's been found! It's called Lady Beth.
