My GF's mom always loved the splatter and drip aspect of throwing Pies in my face. She said the Cream Pie getting on my Leather/Rubber/PVC was a fantastic visual. I've always agreed with that. I love the Cream Pie mess in your crotch and the little splatters on the legs. Perfect! You can still tell that you have Leather pants on.
Don't get me wrong. I Love being covered eventually, but it's the look of the first few Pies and the naturalness of physics and gravity that I like seeing the best.
