Tainty Nine is a wonderful thing. It is life changing. Tainty Nine is a similar to 69, except for one key thing; you pay extra special attention to the licking, nibbling and biting of the Taint. You orally pleasure the Taint. You love the Taint with your mouth, tongue and teeth.
Last night for example, my lover and I were in the 69 position, but instead of just licking for sweet delicious vagina, I nibbled, licked and suckled her Taint. The Taint is best described as this: It "taint" quite her vagina, and "taint" quite her butt hole. It's the meat in between.

"Baby, I'm bored with 69, tonight can we Tainty Nine?"
