Mud because it's free and comes in large quantities.
Messy foods because you get as many different colours and textures as you want.
Gunge because it's far cheaper per litre, it's the closest most of us will get to TV gunge gameshows or doing what we see on gunge websites and you can reuse gunge multiple times over multiple days.
MessySupplies Clayzee Colours; the thick creamy smoothness of clay combined with the vivid colours of gunge! Gives the best of both worlds whilst being pretty easy to mix clean up.
Second choice is MS vivi extreme- thick stretchy stringy ropey slime that rolls around the body wrapping and caressing you. Certainly the most fun to play in; however is a pain to mix and leaves a residue on your skin.
Slime. Love the traditional recipes with oatmeal and pudding, but also love the flour batter based ones. Especially love the way it feels when you are slimed wearing clothes of filling your pants underwear with it!
Thick chocolate like Nutella. The heavy thick feeling on the body is amazing. In addition, I don't like sweet food (including chocolate) so it is humiliate for me as well.
Good question. It is either black bodypaint oil, fake grease or, a weird mix of beet syrup, clay, mineral water and black pigments, since the viscosity is perfect and dripping of slowly...
I love custard . Love the look and feel and it's easy to get . I also love gunge but it's harder to get hold of so cannot really cover myself in it as often as I would like
But my absolute favorites are peanut butter, marshmallow fluff, and cake frosting. The thick glop feels amazing and feels exquisite on my cock. My wife will usually close to the middle of the session stick a jar of peanut butter on my cock and make me masturbate with it.
Shaving cream and lotion because they're pretty easy to clean up while still feeling quite messy! Also my partner recently rubbed coconut oil all over me which was quite hot and it made my skin feel super soft for a few days!
When I was engaging in regular messy fun with a partner, we liked using yogurt. Warmed up a bit, it poured well and provided a great slimed coverage. Good for the skin and easy to clean with minimal to no lingering bad smells. We'd have fun picking out different flavors to try. Mixed well with whipped cream too.
For me, it's chocolate pudding. I think that is the most sensual substance out there. I have always wanted to get totally covered in chocolate pudding from head to toe, but with a female partner. So far that hasn't happened. HA! But a guy can wish.
