going up the dirt track
While searching for the definition of 'digital penetration', I found this little gem.
"The licking of the anal sphincter has been called an ass blow, cleaning up the kitchen, a trip to the moon, and going around the world.
When playing rim around the rosy, the gourmet analist might do so at length, the sampler might do so only briefly, and the cautious would do so through latex or Saran Wrap. The squeamish will no doubt avoid the area all together!"
