As a dominant you sometimes want to restrain your submissive in different ways. The most common way to do it is to use cuffs. Cuffs have a lot of advantages; They are easy to bring along, combi-cuffs can be used on both legs and arms and leather cuffs usually smell good too.
But sometimes you want something more noticeable, something that is maybe heavy so the sub actually feels that the cuffs are present all the time. The solution to this is usually cast iron cuffs that, by nature, are heavy.
There are also different types of yokes that enables you to look arms and head together in different and awkward positions. This yoke is a head and wrist yoke made by Toys4lust.
It has a nice build quality and a visual appeal as well. This piece definitely gets my imagination going. The price is reasonable too and it looks fairly uncomfortable – In a nice way.
