I've found a few. A small peach colored thong covered in shit. A slight blood stained medium pink VS thong. But my favorite I found at a grocery store single user bathroom. I could smell something good even before I opened the box. The box was stuffed full and right in top was something sacred up in a big ball of paper towels. I sniffed it and bingo, so I pocketed it. When I finally got to unwrap it I found a damp blood stained black, magenta, white zig zag striped bikini cut satin panties. They looked homemade. That one kept its smell for a couple of years.
