Sketch Theme Poll for August/September

The winner of the previous theme poll was Broodblimps - Fattening, Inflation, Immobility, Lactation, Hyper Pregnancy, Broodmother TF; and because I, in error, was pretty loose with the theme for June, this is an exceptionally flexible winner.

Starting August, these themes will become a lot stricter and more thematically precise (within reason, naturally)... what this mostly means is that the themes require ALL of its components to be valid—no more picking a single component out starting next lock out (the exception being if a theme has conflicting components).I'm also reverting to the old idea of making the themes a bit more "world build-y" instead of just a collection of kinks or concepts. So, all the themes are now pitched in the form of an item, substance, phenomena, etc.As always, feel free to suggest new ideas in the comments of this poll~! Format your suggestion in a similar way to the poll entries here.
