God idk tbh posture collars are pretty underrated. Nice n tight around your neck and they look pretty nice. Hmmm also like pieces of gear that secure you to your dom like a a harness that's on the Dom that secures the head of the sub to their ass or something so they're forced to rim or suck their dick idk. Also this isn't really a piece of gear but I always loved the scenarios where there's a huge size difference and the sub is stuck underneath the Dom's latex suit and their forced to worship the Dom's musk or something.
