Zoe is the recipient of Brownie’s prototype seamless collar. It’s white gold and locks by magic. And it just so happens only the one who put it on can take it off. Or it should. Dominique put it on, but there’s still some glitches in the design and it’s kinda stuck at the moment. Brownie is working on that. Zoey doesn’t mind though, it’s not uncomfortable. Plus the Twins have noticed it seems to get the guests’ “motors” running a bit more, and has upped the chances of drinkers to pay for a night with a courtesan, so they wouldn’t remove it right now even if they could. And much like the rest of the slaves, Zoey is more than happy to help her mistresses out in any way she can.
