A sexual endeavour between two people, a
Moon Landing occurs when one
person is on their hands and knees, whilst another gets behind them; normally a position know as doggy or doggy style.
Before the
person at the rear enters the
person on there hands and knees, they spread talcum powder (or similar
dry powdery product) over the bum cheeks and bum hole of the
person on all fours.
As the person at the rear is preparing to "land" (enter the other anally with a penis or strap on
toy or whatever they both should wish) they say in a walkie talkie voice "*walkie talkie break* landing in T minus 10 seconds!". They then start counting down from 10 (still in walkie talkie voice if they should choose) slowly thrusting their hips forward at a pace which would allow them to "land" at the count of zero.
As the person counting gets to 2, the person on all fours pushes a fart out, ideally sending the dry powder into the air simulating the moment at which the capsule landed during the official
moon landing and the small thrusters sent moon dust flying.
At the point at which the rear person enters the person on all fours, the person on all fours may wish to proclaim "this is one small step for
man" to which the person at the rear should respond "one giant leap for
man kind"
