Whilst having anal sex, you pull your cock out. With the gaping anal cavity below, you let your spit hang from your mouth as low down as it can go with out breaking, while also trying to sink it deep in the anus. When the spit is dangling inside the anal cavity, you quickly suck it back up in your mouth. Hooray! The event that just happened should resemble a bungee jump!!! :)
Do you have some mouth wash? I need to get the taste of Bung-G out of my mouth.

My wife loves it when i give her the Bung-G. then make out...

When i was in Interlaken, Switerland i went canyoning and did the Bung-G!
