Read only if you're very open minded.

So a while ago, I was using a handicapped toilet at a shopping mall. After finishing with my business, I noticed that inside the rubbish bin was a used pad. The used pad has got quite a bit of dried menstrual blood on it. I was curious and without thinking much, I smell the blood stain and... at an instant I got a very stiff hard-on. The smell is really weird but it got me a lot of dirty thoughts. I actually lick abit of the blood and I felt that my precum was leaking out...
