UK based messy-funner.
Used varieties of substances over the years. Flour & Cake Batter, Porridge, Yogurt, most recently Nutella down to convenience.
Partner isn't too fond on the food, so I do a lot of solo sessions. Sucks a little, but she doesn't mind me playing so, yeah.

Longed to find a good mud site for a while. Probably the only play session I'm dying to try but never found anywhere.
