Introductions discussion

Alright, I’m still getting the hang of this setup and I trust this is the right spot for new introductions. I go by ItsNvrEnuf. I am a married submissive woman in my relationship with a dominant female partner (FemmeDomme). We are relatively fresh to chastity life, though we take it seriously now. It started mostly as playful fun but both of us want to explore the long-term potential. Please guide us along! I’ve been wearing “The Curve” device for about 5 or 6 days already, equipped with some extra attachments like spikes and a mechanism to prevent pulling out. Pegging (PA) is something I’d be open to without issue. My first question goes out to everyone:

1. What makes my current setup inescapable when paired with a PA piercing? I’ve noticed photos showing what appears to be a cable running from the lock through the piercing and back, which looks very secure. Is that part of a specific kit or set? How does one achieve this look/fit? Thanks so much for your help! Excited to learn from you all and have some chats. -Its-Nvr-Enuf
