Now, I should introduce you to something I brought back from my trip. It's a titanium version of the chastity belt you've been locked in this last month. Not the confortable, warm, smooth plastic you're used to by now though.
This one is cast solid metal, the space for your "clit" is smaller, it's lined with sharp spikes, and has a second cage that your balls will fit snuggly into, so long as they're empty.
I call it the "punishment cage".
