I've had this one recurring fantasy for years, and it just refuses to go away. I'm a 38 y/o straight man, and I simply want to fuck an underage girl -- perhaps 13 or 14 years old -- in public. I want people to notice, applaud, and encourage me to fill her little pussy with cum. And then I would.
Of course, this fantasy has precisely zero chance of fulfillment. It's illegal in every state (as it should be.) If I tried it for real, I wouldn't be applauded; I'd have the crap kicked out of me by the (justifiably) pissed-off onlookers. And yes, I'm quite the pervert for even dreaming this one up. But there you have it.
