I got the idea, for a modified bicycle saddle, and so I made up this edition, meant to hold a guy.
I have sort of made two modifications:
1/ I have supplied the saddle with 3 steel rings, and 2/ I have made a hole in it, to hold the ballsack.
Here you see the results of the modifications (with cock and ball sack 'mounted' that is)...
The procedure is actually rather simple, if you feel like copying the idea.
You might need to turn the bracket, holding the saddle onto the saddle post like I have done here, in order to avoid having the top of the saddle post blocking the ball-sack-hole.

As you see here, the bracket holding the saddle has been 'turned over', in order
to allow for the ball sack coming out on the bottom side of the saddle.

Another interesting fact is how little people actually see, in
the street... Click here to see for yourself ![]()
Developing the project, part 2:
Here I have given the saddle a 'gold look', but apart from this, I've mounted
a buttplug to the saddle.
The buttplug is made from a piece of wood, and is 2,8 cm wide (1 1/16"),
and 12,8 cm tall (5").
Developing the project, part 3:
Here I got the idea, to make a go for designing "the ultimate bondage saddle" with buttplug and cock-binding.
Here you see how cock and balls can be bound to the saddle.
this is a close-up, of the u-bolt, I mounted at 'front end' of the saddle, in order to tighten it around my cock, just behind the head, in order to be able to lock the cock to the saddle.
Here the saddle is mounted, on my bicycle, ready for a test-ride...
Most unfortunately, it proved, that I had forgotten how much of the body
weight the saddle support while riding.
The unfortunate fact is, that I'm not enough of a pain-slut, to let my privates
support that kind of load, without the support of 'sitting on my buttock' - and
so the test-ride was cut short, which in effect means, that there is no video,
of the test-ride.
Getting wanked in the saddle - Developing the project, part 4:
Next step in the development of the "bicycle-sex-concept", was to build a wanker, powered by the bicycle.
This item has got it's own page, which you'll find here: 
-I made a test-run (two actually), and you'll find the video here: ![]()
-and the video, of the successful modification here: ![]()
Another set-up for the saddle - Developing the project, part 5:
I got the (crazy) idea, to attach my bend steel tube, to the saddle, along with a 'ball-splitter'.

The saddle with the steel tube attached.

Here you see the ball-splitter-rim
(opened)... -and
closed...
-and the locking-mechanism.
The ball-splitter is designed like this: The rim starts at the 'front-side'
of the ball-sack hole, makes a loop under the ball-sack hole, runs through a
chain link, which I've mounted on the 'rear side' of the ball-sack hole, and is
finally sewn through a 'key-holder-gadget', which can be split in two halves
(opened), by pushing the ends towards one another.
When I mount the saddle, the rim is not 'locked', in order to let me get my ball
sack through the saddle.
Having gotten the ball-sack through the saddle, I tighten the rim, and 'snap'
the key-holder-gadget closed, which in return pull the rim up between my balls.
This split the balls, on the bottom-side of the saddle, and has the surplus
effect, that they become 'tightened up', in the most delightful manner.

Yet another option - Developing the project, part 6:
I got the idea, that when I have a bicycle, with rear-suspension, I just
might make some use of this (or rather of the fact, that the spring is moving,
when getting compressed, and decompressed).
Having gotten the idea, of making some fun of this, the idea to apply my vacuum
pump to the suspension, making it 'pump' while driving, was not far away - and
as it usually is with me - there were not far from the idea, to the actual
project.

As you can see from the picture, the hinge, connecting the rear-wheel
suspension to the 'main-frame' of the bicycle, is located just behind the crank
axle bracket.
The spring, intended to give a more smooth ride, is located a little higher,
than the crank axle bracket .
Finally I've mounted the vacuum pump (using plastic strips), from the rear of my
luggage carrier, to the 'main frame' of the bicycle, just below the saddle post.
The (obvious) point is, that when I drive over either a bump or a hole, the
piston-action of the pump will inevitably create vacuum.
The reason why I have mounted the pump, as far up, from the hinge, as I could
possibly get, is thar the further you move away from the centre of a circle, the
bigger the movement, for a given alternation (in degrees).

As you can see from the above graphic, where I have placed a 'measure' at the
height of the spring, and (the same) 'measure' at the height of the pump, I get
twice the action, at pump-height, compared to 'spring height'.
This means, that if the spring is compressed ¼", the piston, inside the
pump, will be moving ½".
The details of the pump can be found here.
The point in combining the pump and the display tube here, is, that whenever
the pump is compressed, some air will pass the valve inside the pump.
When the pump then is uncompressed, air will be drawn into the pump, through the
valve, at the tip of the pump.
This will then have the effect, that air is pulled into the tube, from the
display-tube, attached to the saddle - and as the air (because of the valves)
only can flow in ONE direction, the result will be, that the vacuum in the
display tube will increase.
Here I've cut two pictures into one, something like a "before-and-after", with the result of the videoed ride displayed, with the "before" at the left side of the picture, and the "after" at the right side of the white line.
Here's the bicycle, dressed up, and ready to make video.

Yet another option - Developing the project, part 7:
Here I've replaced the first ring, with a U-bolt. This U-bolt then has been supplied with two wing nuts, which I've modified to be lockable - by means of a small padlock.

The point being (of course) that when the U-bolt is tightened behind my cock head, and the wing nuts are locked, my cock is, in effect, locked to the tip of the saddle.


The U-bolt is placed in an indention, on either side of the saddle tip, which I have filed into the saddle, and 'skinned' with electrical tape.

Yet another option - Developing the project, part 8:
Next I got the idea, to develop a completely new saddle concept. This one was to have 'nothing' underneath the cock and balls - just for the sake of variation..*S*
Here you see the saddle, with and without my cock-shackle, and from different angles.
As I - in my mind - refer to this saddle as the "Multi-flex-saddle" I expect you to await a series of different application options, and if so, you're absolutely right.
Here is a series of different examples:
Option 1a/ Cockring and line (shoelaces)
Option 1b/ Cockring and line (shoelaces)
Option 2/ Long glass (with vacuum)
Option 3/ Carafe (with vacuum)
Option 4/ Hyalite (with vacuum)
Option 5/ Cock-shackle and line (shoelaces)
The cock-shackle is made from a piece of 3mm aluminum-stick, purchased at my
local Silvan.
I have bent it into shape, to get the 'eye' at the top, and so, that it would
fit into the two holes, at the tip of the saddle's two 'horns'.
The rest of the setup is a military bootlace, and a shoelace purchased at my
local Tiger store.
The mounting bracket, for the saddle post, is a/ a bracket from my local Silvan, which I've modified to suit the purpose, and b/ a saddle post bracket, from an old saddle. *G*
Yet another option - Developing the project, part 1, version 2:
.jpg)
Having stated the point, that people in the streets, don't see a thing, by
driving through town, with my cock and balls covered by a thin nylon stocking, I
was rather convinced, that they wouldn't see a thing, even if I let go of the
nylon stocking...

This proved to be true, when I tested my assumption..!
You'll find the video, if you click here:: ![]()
Yet another option - Developing the project, part 5, version 2:
When I set up the saddle with the steel tube, I also attached a ball-splitter-rim. Now I've taken it one step further, making a ball-splitter in stainless steel...
The manufacturing comes in 2 parts; as the saddle post as well as the saddle is involved.
To start out with the saddle post, I got the idea, as I found out that this saddloepost comes with a bracket, where I can attach a 'loose stick'.
.jpg)
Here you have the saddle post in question, in 'exploded view'.
.jpg)
Here you see the bracket, in which I've drilled a hole for the stick. It's
placed on top of the sticks, under the saddle, when holding the saddle..
.jpg)
Here you see the stick, which is supposed to fit into the hole.
It's made from a piece of Ø6mm stainless steel, and has been carefully
polished, in order to avoid any 'sharp edges' which could 'bite my balls'..!
.jpg)
And here you see it, placed in the hole.
.jpg)
At the saddle I have placed an eyelet, in a hole which appeared to be
perfect for this purpose.
It is holding the piece of aluminum pipe, which can slide in over the end of the
stick.
.jpg)
I have squeezed one end of the aluminum pipe, drilled a hole, and then mounted a
key ring, in order to get a good grip.
.jpg)
Topside I've attached a piece of ½pipe, and a ring, which will grab my cock
just behind the head.
.jpg)
Here you see the complete ball-splitter assembly.
At the left image, the aluminum pipe has been pulled out, to show the end of the
stick, with the stick placed where it'll be when 'closed'.
At the right image I've opened the stick up, as it is intended to be before
being closed.
.jpg)
Here you see the ball splitter closed, with the aluminum pipe pushed in over the
end of the stick, thus 'locking' the stick in place.
.jpg)
And here you see the whole thing assembled and closed, splitting my balls under
the saddle...
