Back home on the farm, I had a close friend who worked as a sex-phone operator when she wasn't milking goats. One memorable day, she demonstrated how to make the sound of a wet pussy.

Though I can't attest to the veracity of her claim, I often make the sound to entertain loved ones. Above is the sound of me demonstrating "Wet Pussy for Sex-Phone Operators". Below is "Bonny Black Hare" from the album "The Bird in the Bush" Traditional Songs of Love and Lust".
