this procedure takes a lot of practice to perfect. the first step involves removing your trousers. after that, you may find a partner of either sex to perform this process on. clothes are optional for your partner. at this point in time, it is now necessary for you to drop a load on the face of your partner. continue to deliver your stinkage until the face somehow begins to bleed or until there is no possible way to unleash anymore stinky. you may then put the finished product in the freezer and enjoy it the next day for a scrumptious supper

Before partaking in an act of 69, defecate in an old pair of underpants and pull them down to allow your penis to move freely. Then, as you are about to ejaculate, let the excrement flow out of your nappy onto your partner's head, taking care not to let it flow out prior.

Strategic timing and handling skill is necessary to execute this one. It's not for the faint-of-heart.
I was parked in the rest stop when, out the back, I saw an adventurous young couple performing 69. They did a Wyoming dump truck at the end; it got everywhere.
