A curious one - hear me out.

A few years back I came across these squishie stress-toy cakes you can buy and thought it might be fun to get one to sit on as it could offer the visual appearance of sitting on an actual cake, except that the cake would return to its original form after it had been sat on, so you could do it over and over. (If only that were possible with real cakes!) Of course, this isn't really messy, just the appearance of crushing a cake, so as yet I've never purchased one of these squishies although I might one day for a little fun.

More recently I DID purchase some "Ooze" slime, and have really enjoyed playing with it. It's funny because whilst very gelatinous, it doesn't really stick very much. This means I can put my cock in the tub or take it out and stretch it over myself and it generally is super easy to clean up and can be used again. OK again, it's not really messy, but it is still fun to play with.

Just wondering if anyone else has had ideas on the notion of reusing WAM materials (or how many times you've reused old slop from a previous session )?

There is a product sold in the USA called 'Yuck' which comes in several textures. The stretchy, gooey one is the one to get. A little of this goes a long way. You can pre-mix a container of it and it will keep for a very long while. It is basically a non-toxic liquid plastic. If you choose to mix up a large batch to play with and put it back in the container afterwards, it will still last a long while. What turns most substances bad is our own human bacteria that gets in it. This is why pools generally use chlorine, where the water flowing in a creek tends to be cleaner.

So if you're planning on re-using any wam substance keep these things in mind:
1. Don't use food-based substances
2. Pre-shower to reduce the bacteria you might introduce into the substance
3. Store in a sealed container
4. (optional) treat with a product meant for spas or pools, being very cautious about how much you use based on the amount you wish to preserve.
5. Keep your bodily fluids out of the substance.

Most slimes are based on plants, such as methylcellulose, guar gum, etc. The plastic-based slime I mentioned will out last the others.
