I agree, the few videos that Little Red shared with us a couple years back were amazing. The thing about those stocks, from looking at the video, is that they were made specifically for her. So if my models were all exactly the same foot size, I could rig up something pretty nice. But since they're not, I've had a heck of a time trying to fashion a bondage device that's portable and allows one to fully restrict a foot, while adjusting for various foot sizes.
I've been practicing on my wife for a couple years now, and it's been difficult so far.
Because trust me, I'd love to have that capability too!
If anyone in the community has good carpentry skills, and like to tackle such a project, I'd sure like to make it worth your while to help us out.
