My messy dom has asked me to come onto here and make a post where people can give me messy dares to complete. Be as mean as you want

I'll start tame, just one classic shaving foam pie!!

How about a peanut butter shampoo and smeared in your armpits

get yourself a pair of plastic pants and fill them with custard while wearing them

try cake mix as slime mix to flavors and colors together and pour it all over yourself to be two separate colors
Half one side and half the other of the body

How about tight jeans closed off at the ankles and then filled with every kind of messy, smelly and slimy thing your dom can come up with? Oh, and you have to be wearing no underwear...

Get a couple of frozen cream pies, thaw at room temp. 1.5-2 hours, but check and make sure it's no longer frozen. Then slowly pie your self with each one, don't forget to taste that cream!
