This secret piece of jewelry can be hidden anywhere on the body, or even just kept in your pocket! Anyone with the same app will get a notification that a free use toy is in their vicinity and offer for your exact location to pursue. Endlessly customizable, you can set it to simply be a cum rag so anyone can use your face to get off. Maybe you just want to be subtly groped in public. Or you can escalate: anyone who gets a ping can literally drag you to the nearest bathroom or secluded space and use you to their heart's content. The carefully negotiated user license outlines the most important part, which is you can't say no once you step into public. If you didn't want it, you'd turn it off or leave it at home. But that's what you love about it! How easily strangers grab you and play with you, no questions asked. The key tag lets them know you're available, but something about the look on your face is what really asks for it.
The ideal arrangement, of course, is for your owner to implant a key tag under your skin as subdermal jewelry or some other non-removable piercing. They just set it to whatever level of violation they want you to experience, and out you go! No say in who uses you next, where or when it happens, how long it goes on or far it goes. If you weren't so turned on, someone might worry you actually don't like this. Of course, once a stranger grabs hold of you and drags you off, they're not thinking much about how you feel anyway.
