Plug with a leash?

I saw a video once where a girl was being walked around on the floor on her hands and knees, but instead of her leash being attached to a collar, it was attached to the end of her buttplug. The only other time I’ve seen something similar was in a chastity caption image collection on imagefap, where it had a girl with a plug that had a chain on the end that connected to a guy’s chastity cage. Her end of the chain was simultaneously connected to two piercings in her labia. The idea was that they had to sleep together all night like that and the chain was fairly short. 🤭

Does anyone know of a product like this? I find the idea and possibilities very exciting but haven’t been able to find anything online.
