It's interesting. Almost any erotic image can be reimagined with a different dynamic, simply by picturing oneself in the picture but in a chastity belt.
For example:Very much an Orientalist picture: it's the Exotic East, an African slave pampers a languid harem inmate.
Now imagine that this is seen from your point of view, and that you're waiting patiently to serve your mistress, a chastity belt welded around your loins.
And perhaps once mistress is done, you and the handmaid share a cell. You can't see it, but she's also locked into a chastity belt. However, she can get off, if only you tease her nipples for long enough.
