Their slime is made out of the same ingredient as most water based lube (just nore thick and gooey) and colored with crayola-type powder paint. It's about as nontoxic as anything you can stick in any hole.
If you have any sensitivity to yeast infections or UTI's, I would caution against using cake batter slime.
Can't wait to see how this turns out. I love nothing more than a beautiful woman filling all her holes with gooey slime.
Fourth shoutout for Splatter Emporium. The regular slime is on the runny side, I recommend the thick or extra thick. Follow the mixing instructions, using a drill attachment is highly recommended to prevent clumping. Several colors available. Cost and shipping time are reasonable. Cleanup is fairly easy as it can be rinsed down the drain, minimal staining from the slime but be careful handling the powder. We haven't done intentional direct insertion with the slime, but have directly poured it *everywhere* with incidental insertion, and had no issues.
