You are not going to believe...
You are not going to believe what I found for you at the chastity superstore.
This new cage has a six-digit combination lock, so no more "accidentally" finding the key. It's made of unbreakable molybdenum-steel - you'd need a blowtorch to get through this thing. Best of all, it has a built-in, wireless-enabled teaser with anti-orgasm safeguards. I can tease you with my phone, any time I feel like it, no matter where you are or what you're doing, with no warning whatsoever.
Won't that be fun?
