These are Pizza Panties, currently a well-underfunded Kickstarter campaign for a thong that looks like a piece of pepperoni pizza. $15 will get you a pair if you're an early bird and they reach their funding goal, $20 will get you a pair if you're a slow bird and they reach their funding goal, and all the money in the world won't get you anything if you're a dead bird, regardless of funding goals. Me? I just melted some extra cheese on the crust of a real piece of pizza and stuck it to my privates. It hurt for awhile but I think I'm okay now. I just took a look at myself in the mirror and I think I'm a dead ringer for Adam from the Garden of Eden provided the Garden of Eden was actually a Pizza Hut.
Keep going for a shot of the rear, which is way stringier than I had imagined. Like melted cheese!
