Oh man, this looks just like something I made recently! We have similar tastes :P Who do you go to to get latex parts made?

Oooh cute! Does that mean I could buy the fluffeh version aswell as have an inflatable one? :D

I used to use Squeak Latex but I don't think they take one off commissions any more, so I don't really know who to use. Any suggestions?

No, I don't :( Squeak Latex is the only latex stuff maker I can think of... And my fluffy version is up for auction right nooow! *shameless plug*

Archean at KinkEngineering (kinkengineering.com) has experience with custom work and making inflatables, and could probably handle a job like this. I'd suggest Pretty Pervy, since they designed and made a lot of the original latex critters floating around, but they closed up shop a year or so ago. Zebrathingy on Fetlife makes custom latex critter gear as well. Obsidian Design (http://obsidian-design.co.uk/) has made some custom underwear with tails, and may be able to do this as well.

Good luck! Looks like a great concept :)
