This one is neoprene and is very comfortable, although it does not have a D-ring attached:
A different one I have is similar to this except it uses Velcro to close (so it is adjustable) and has a D-ring, to which Mistress can attach a leash to lead me around with, or even a clasp that she can attach to the handle of a drawer (or?) to hold me in place.
Here is another version of essentially the same thing, although again, no D-ring:
Wearing my balls harness is probably my favorite thing to wear under my regular clothes (other than my glass butt plug). It pulls and holds my ball comfortably away from my body in such a way that I always aware they are there, and therefore constantly reminded that they are the property of my beloved Mistress.
These pictures have absolutely nothing to do with the topic at hand. They just make me horny (smile) :
Have a great weekend everyone. Submissive brothers and sisters out there, love your Dominants! Dominants, love your submissives. We are all so very lucky to have each other in our lives.
