It's got to be pies, although it's hard for me to explain why. Even from a young age before it was sexual I got a "forbidden" feeling about girls and pies. As I grew older, it evolved. Let's just leave it at that.
I suppose it would all depend on how easy the 'clean-up' would be.... An 'easy' clean-up out-doors; a creek, a pond, even a garden-hose would be a great way to clean-up. So the sky would be the limit !!!
But if you had to use your bathroom; tub, shower, etc., it would be a lot different.......
My personal favorites ??? Mud, pies/cakes/food, water-sports, and if it was the 'end-of-the-line' for your gear, paint, and used motor oil, so everything ended up gettin' torn and ripped up, so no need to 'clean-up' !!!
And to answer the second part of this question, 'Because it feels so good !!!'.......
It's MessySupplies' 'Clayzee Colours' Simply put it's the smoothest, thickest, most vividly coloured 'gunge' I've found to date.
How smooth? I use a plaster mixer in a drill and it's an easy smooth mix. Jazz cafe on a rainy afternoon smooth.
How thick can it go? Like thick mud- plunge a hand in and it'll squish into a vertical cliff around it. If you pour it out it'll splat down in big satisfying lumps. [It also mixes thinner too- makes for some excellent gunge pours]
How vivid? It's bentonite clay- making it fully opaque even in a thin layer, which makes the colour really intense.
It's also got the added bonuses of being pretty cost effective (£/Litre of gunge), and from my experiences it cleans off the skin easier than other gunges and has almost no taste/smell.
Custard has always been a fav of mine, you can use it warm or cold, mix it with other stuff like swiss rolls to make a thick mud like substance thats still edible, and its pretty much ready to go from the packet esp 1kg packets
i have been enjoying messy cakes alot lately, getting all dressed in the outfit i'm going to use, then going shopping for messy cakes and using them as soon as i get home, sometimes i dont make it home before i start!!
Melted ice cream with root beer poured over top is absolutely amazing. The scent is nice, the taste is great, but the sensation of the carbonated soda reacting with the ice cream is just a full body experience that is quite difficult to explain other than crackly....
A thick slimy substance that is slow to consume your whole body, smooth against the skin, has weight, density to slow your movement, sticky to resist your withdrawal, warmth to calm your anxiety, a sensation against the skin that touches your every nerve.
Bentonite clay I've spent the most of my days in. Shave cream, white glue and contact lens cleaner (borax) using my body to mix, is like marshmallow fluff, extremely sticky at first then fluffy and soft until it loses is fluff then heavy and slow oozing days later. Sodium polyacrylate in a large lank suspending my whole-body nude feeling every inch of skin being stimulated by it's texture driving me to rock against it until handsfree orgasm
