Blood!
Okay so I straight up have a blood fetish. I like the texture of it the most. Its similar to melted ice cream, except warm and not as sticky. I get my blood by cutting myself, although I'm sort of a wimp so I only cut my fingers and get as much blood as possible and use that. My favorite things to do with said blood I to drink it, or I'll take a blade, cover it in blood, and lick it off slowly. Sometimes I will use the blood to masturbate. Its wrong, but its sooo sexy. I fantasize about sex with women covered in blood, licking it off and just feeling it. So yeah... Blood.
