Basically myself and one other friend decided to let our gerbils out to play on the playground, but in order to stop them running away we sat on the ground with our legs apart, facing each other so that our feet touched, effectively forming a leg-barrier between the gerbils and the outside world. Being a tomboy I wore trousers all the time, and you could have knocked me down with a feather when one day a gerbil decided to investigate my trouser leg and ran all the way up to my crotch and back down the other leg. I giggled insanely because it tickled, but soon discovered that I enjoyed the sensation of a warm, furry creature tickling my inner thigh and myself and my friend (also female) began to encourage the wee creatures to do so more often. We were so innocent. I actually can't believe how incredibly dodgy it now sounds. Does this make me gay? Did anyone else do the most horrifically perverse things because it tickled?
