My idea was to build a doll with a foam core and a thick latex skin, say maybe 5mm thick. No silicone. The foam would need to be hollowed out in certain parts (breasts, inner thighs, belly, buttocks and around the pussy) so you would have a half inch gap between the foam and the outer skin where the water would run. Therefore, the heated water would be right in contact with the skin surface, making heat transfer possible. A waterproof, closed cell foam would need to be used. Two part soft pour foam is available. The middle of the chest, the 'ribcage' i suppose, would be hollowed out to make room to install an aquarium heater and a submersible pump. If these were installed just behind the breast area, possible access could be acheived from the neck for replacement. I already have ideas on how to do this.CharlieWone wrote:Just keep in mind one basic issue- silicone does not transfer heat with any efficiency whatsoever.
The max temp of an aquarium heater is 35 degrees celcius - - not quite a human 37 but close enough.
Think about it, women are not soft all over. Poke your ribs - pretty firm, right? The same with outer thighs, much firmer than inner thighs. The same with the back - not much give. These areas would remain foam. Most of the pelvis would be foam, exept where you hollow out for the pussy and part of the belly area.
Of course only the areas with the water jacket would be successfully heated - - but think about it. Does she need to be warm all over? Think about sinking between those soft, squishy WARM legs and pussy - nothin' else would matter much.
Lets think about those key areas again - - breasts, inner thighs, belly, buttocks and pussy. If the latex skin was thick enough and the water jacket was thin enough, about half an inch is all that would be needed, i believe this would act close to real flesh - a deadpan fleshy liquid wobble and not the elastic 'snap' that you tend to get from silicone.
Take a womans breasts - they are almost liquid - the way they flatten out when she's laying on her back, the softest, most beautifully squishy things you will ever lay your hands on - silicone breasts are simply not like that.
And then there's the tactile quality of latex - simply wonderful. You don't need to keep powdering it like silicone. Power once, and it remains completely tack free for a very long time. Very very good mimic of human skin.
I guess it's really quite hard to express in so many words the complexities of my idea, but i hope you get the general idea.
