Please explain what did not work? Was it:-
(1) The melting of the suppositories into a liquid, and then pouring the liquid into a mold (alfoil tube, finger off a latex glove, etc) to reform into one big suppository? ,or;
(2) The effect when it was inserted?
The suppositories suitable for melting down and reforming into a supersuppo have a waxy look and feel like white candle wax.
I have seen some suppositories that look almost clear and they feel rubbery rather than a waxy. These ones don't seem to work very well as suppositories, even straight out of the packet.
I believe that the waxy base used in suppositories is called cocoa butter, and this melts very easily into a liquid.
We have a similar substance in AU called Copha, which is solidified vegetable oil. Copha is used to make novelty sweets for children's parties. You melt a block of Copha in a large saucepan, then add icing sugar, drinking chocolate, and a packet of Rice Bubbles. Then scoop into paper patties, sprinkle with coconut, and put them in the fridge to solidify. Kids love them.
I've also made big suppositories using Copha. I left out the sugar, chocolate, Rice Bubbles etc, and added glycerine and a pinch of salt instead. I used the fingers cut from latex gloves a molds. And, yes, they did work very well indeed.
Hint: Stand the cutoff glove fingers in narrow liqueur glasses and then fill the finger molds. That way you can stand them upright in the fridge while they set. When they harden there will be dimple in the top, and this really makes insertion easy.
If you are perverted and add too much glycerine, like I did on the first try, then the Copha will not harden properly. No big deal, just re-melt these with some more Copha added and try again. Re-melt everything very slowly. Do not turn up the heat just to make it melt faster. It's going to be up your loved-ones bum for a lot longer, so melt it low and slow and keep stirring and breaking up solid pieces of Copha with a spoon until it is all liquefied. Re-pour it into molds straight away.
