A jolly rauncher is when you put a jolly rancher in someone's twat with the end sticking out. When you go down on them it's there for you to suck as you lick the female. The taste of the rancher spreads as you use your tongue and it tastes incredibly good. Watermelon is the best flavor; sour apple is not recommended.
I got a great Jolly Rauncher last night. Freddie came over and put a watermelon candy in my pussy and licked me all night...it was incredible.
