My first experience was with a Mistress Cleopatra, who advertised in "Screw" magazine. It was many years ago, but I am alive and kicking and still in the scene.

My mistress did not force me to consume, but was very forceful in her demeanor and I managed to consume much of her movement. My recollection (albeit likely skewed and dimmed), was that her shit was not that bad and to this date, the "sweetest" movement of them all.
