I'd have to say the fantasy that gets my juices flowing is to be gang-banged.
Here's the scene:
I'm in a dirty, run down bar out in nowhere and it's filled with at least 20 eager, disscusting, men of all shapes and sized and most are well endowed. I come in wearing a flared out mini with it just past my ass cheeks and a blouse that ties in 2 places in the back so that my back is exposed. I flirt and drink until I'm quite tipsy, then I'm ready to go but all the men who have bought my drinks think differently.
They take me in the back, strip me and strap me to a saw horse, cuz I'm sure there's one laying around somewhere, lol, then every man takes full advantage of every hole all night long!
I just love the thought of being totally helpless and with all 3 holes filled at the same time until I am just plain raw!!!!
