There’s something about people in uniform which is strangely, unexplainably but undeniably sexy. Whatever you’re into, whether it’s police officers, doctors and nurses, soldiers, or any other kind of professional, when somebody puts on their uniform, it has the power to turn them from a regular person into a sex god or goddess. Perhaps one of the sexiest of them all is the fire fighter uniform. This uniform shows that someone is brave and tough enough to save you from a burning building; holding the fire hose or fire extinguisher to save the day, but also gentle and caring enough to rescue a kitten from a tree. Fire fighters are the faces of loads of calendars all over the world, showing off their super-fit bodies shamelessly.
