Chastity in the Digital Realm

Counting down the days until Thursday! I’m picking up a CB6000, along with some nipple clamps, a long blonde wig, and lockable rubber cuff accessories! Lately I’ve been getting into online domination. My mistress has me in chastity mode right now. The only issue is: if I purchase the cb6000, can she still keep me locked up even though I hold the key? Since we won’t be seeing each other for a good while, having her physically possess the real key isn’t an option.
