Today I use tissue, but you remember in high school when you used to use that ol nasty cum rag that you had stashed under your backpack in your closet so your mom wouldn't find it? You know, that one that had so much cum collected on it turnt yellow and was hard like a rock?
I had one of those laying around in highschool. Me and a friend were in my room getting drunk one day and it was really hot up there. My buddy grabbed a random rag on the floor and wiped his sweaty face with it. He wasn't pleased when I told him there was a litre or two of dried up cum on that rag.
