I made a magic wand harness out of heavy chains! Young Emma Evans was the first to try this contraption. I think it should stay in place quite well, even though I need to add a lot of extra padlocks to keep it centered. It worked very well, as Emma found out. She was chained overhead with heavy cuffs, so there was nothing she could do to stop the vibration on her pussy. Emma is so cute and submissive, she is always up for any experiment I come up with. A great test model for predicaments like this!
As for the magic wand harness… I would say it was a success! Try and build one at home, it is so much fun!
