i discovered this kink awhile ago but only recently started doing it, I started small with shaving cream and chocolate sauce and moved on to to cake batter and gravy and of course cakes
I'm looking for any ideas to add to the experience, as well as tips for cleaning up and avoiding smells
If you're doing solo sessions, I'd recommend using either a bath or shower as your location for getting messy. This saves so much time on cleaning.
If you're using foodstuffs like cake batter, custard or sauces, make sure to dilute it with plenty of water before letting it go down the drain. If you're using anything that could clog the drain like cakes or chunkier items, scoop it out and flush it down the toilet or chuck it in the garbage.
As for smells, obviously avoid strong smelling substances. Also avoid dairy products as they leave a lingering smell especially if you miss a spot in cleaning. You could try gunge as it's quite easy to clean and doesn't leave a smell, it also tends to be cheaper quantity-wise than say cake batter; I'd recommend messypup.co.uk
Using 'proper' gunge is the best bet to avoid smells - just take care to wash every nook to remove traces of colours. I loved using stuff like custard / beans / rice pud / pasta sauce when I first started, but they STINK!
For cleaning - a shower scrunch thing usually works quite well and can be effective at cleaning out the folds in ears etc.
Echo using messypup - their stuff is good quality and packaged discreetly and well priced. You can also get things like slime baff from online places that have locker pickups if you have a shared mailbox etc
Else getting Xanthan gum from the supermarket (where they keep the gluten free stuff - it's in a small cylinder container) might be a good start. It's a sod to mix - Luke warm water and use a balloon whisk or something to get a really good swirl going and keep mixing til the lumps are roughly gone. Add some poster paint to colour it!
