First of all would just posting some of the dong tfs i am coming up with be better or just coming up with a store to place them all in be better. Off the top of my head I can think how to make colder dongs, hotter dongs, vibrating dongs, fizzy cum. Also possiblities for fuzzy furry dongs, downy feathered dongs...i'll stop here.
Hmm the temperature would actualy be something of a pelvis tf to be in line with a sci-fi transformation. Couple of animals already have some heat exchange things (usualy for cooling off body part, blood). Idea is mostly something that would cool off or heat up the circulating blood in the donger, resulting in a temperature change. Yeah bit icky getting invloved with fiddly bits of fictional biology, but makes things possible if you stop to think about it. (hmm lubricating glands, something like saliva glands in a sheath to have a self lubing cock?). I'll stop here before i come up with anything else before hearing back from others. (interest, discoragement and so forth)
