Ever wanted to make a mould of yourself (or someone else) so you can stick you up your ass? There are a fair few mould-a-willy kits out there but I’ve tried a couple and they all leave a bit to be desired. You can, though, buy the bits to make your own. This probably won’t be much cheaper than the kits but you’ll have the materials to make a few though and it should be a better result.
The idea will be to make a negative impression using alginate then cast the final dildo from platinum cure silicone.
You’ll need: alginate (like the stuff the dentist uses to take an impression of your teeth), platinum cure silicone (make sure it’s food safe), silicone pigments of your choice (again, food safe) and finally a plastic cylinder a few centimetres larger than your, er, girth. You can get most of these from eBay fairly cheaply.
Obviously the same technique can be used to mould anything, including fists!
Prep:
You probably want to shave all your hair otherwise pulling it out of the cured alginate is going to be painful. You can also try using some vaseline as a barrier but the less hair the better.
Some of the alginate is going to drip so throw some newspapers down and cover a chair.
You’re going to need to stay hard for a couple of minutes in fairly cold goo so grab a cockring, poppers and porn to help :)
Making the impression:
Decide whether you want to include your balls, or not, in the cast. This will then determine the diameter of the plastic tube you’ll need – allow a couple of centimetres either side for the alginate as well. A drinks bottle or poster tube will work just fine. Cut one end of the tube at an angle so that the main part of the plastic tube is parallel to your dick when you’re hard and the angled end fits flush against your body (otherwise the alginate is going to drip out a lot).
Mix up the alginate according to the instructions – the better ones are colour changing and go from pink to purple when they’re ready to use. Colder water will give you longer working time but you’re probably only going to have a couple of minutes at most before it goes white and has gone off. Get yourself prepped and fluffed before mixing the alginate up!
Pour the alginate into the tube around your bits making sure you’re not pressed up against the inside of the tube and that you fill a good few centimetres above the top of your dick. Some is bound to dribble out the bottom but you should be ok to keep filling.
Once the alginate has set you can pull out (letting yourself go soft will help) but leave the mould inside the plastic tube.
Silicone moulding:
The platinum cure silicone is the same kind of stuff that square peg use and you can colour it as you like – the base is a sort of translucent colourless affair. Make sure it’s food safe! There are often different textures too so you can have hard or soft but for a dildo I’d recommend the harder compound.
It comes in two parts so mix up the silicone with the catalyst as per the instructions, along with any colouring. A mixing cup and scales will help – it’s important to be accurate.
Hopefully you’ve left the alginate in the plastic tube so it’ll be easy to up-end and then pour into the top. You can leave a bit of a flange on the top if you like; you’ll be able to see how thick it is through the tube.
Leave it to cure then remove it from the tube and alginate – sadly the alginate will crumble so is really only a single use. If you want to make lots then take a plaster positive first then stamp out alginate negatives with it.
