Here you see the cock'n'ball crusher in it's separate parts.
Here two close-up's of the ring, which is intended to end around the cock.
The cage itself is made from a 'patent-band' of metal, which is assembled at the
crossing, with a short bolt, and a nut, which covers the end of the screw
completely.
This is the 'backside-plate' which will force the balls into the holes, in the other half.
This is the 'frontside-plate' with the openings, through which the balls are
intended to be pushed out by the 'backside plate', see from two different angles
The rod, which will be between the balls, is a piece of aluminium tube, which
I've glued into place, in a Ø10mm hole drilled through the plate, prior to
drilling out the two large holes.
How to 'mount' it:
1/ Start with the plate without holes behind the ball-sack..
2/ Lay the plate with the holes in front of the ball-sack, so that the screws
come out through the holes for that purpose.
3/ Now you attach the two wing-nuts.
(If you want the balls to protrude very distinctively from the holes, you would
need to pull out the skin, from your ball-sack, through the holes, to give
suficient space, to allow the balls to 'pop out' through the openings - I'll be
getting back to this).
4/ Insert the screw from the cock-cage into the tube dividing your balls.
5/ Insert as much of your cock as you possibly can through the ring, into the
cage.
6/ Attach the wing-nut to the screw, from the cock-cage, on the bottom side of
the tube separating your balls.
7/ Now you tighten the wing-nuts to your liking (or to your Domina's liking *S*)
And if you used the opportunity mentioned under 3/, you'll get a look something like this!
