Public Places
I get really horny during the day when my girlfriends at work, and I like to take my laptop somewhere public (like the library) and read erotic stories until I'm so hot and wet that I can't stand it, and it feels like everyone around me must know. Then I go to the restroom (I make sure it's empty, the thrill of maybe getting caught makes me even hornier, but I don't think I'd want to ACTUALLY get caught), and I masturbate until I have an orgasm.
