You know those rafts that you blow up and float around on in the pool or the lake? The marines call these "rubber ladies." Do you suppose it was an enterprising marine that invented the blow up adult dolls?
The thought that there are people somewhere near me (probably in my neighborhood) with a real rubber lady is quite scary. What sort of solvent can you use to get Vaseline off of rubber without dissolving the rubber itself? Or do they just let it crustate? Or do they not even lubricate the cold rubber they are pounding? I just don't get blow up sex dolls. Is it because you can make them tighter by using more air?
