To drink effortlessly, I need a few things and preparations.
1) Drink a ton of water to hydrate, then switch to beer - usually get three in you before unloading
2) Take a huge hit of poppers before you want to drink
3) Get that buzzy lovey dovey sensation while you let your tongue explore the piss slit and his head and shaft as the jet is unloading inside your mouth and gulp like you mean it. It comes out with a huge velocity to so expect a lot to come out the side of your mouth. When guys tell me they take every drop, I am impressed - to do that, you have to have the same ability to say, shotgun a beer or do a beer bong. I am a wussy an can do neither, but once you start, the beer piss will make you more buzzed.
4) Go down and have three more beers, and this time, your Redneck Budweiser (recycled beer) will just keep on adding to your fun.
That's my plan of attack. If I get nauseated, its only after because I think about how much piss is in my belly, but I get hard thinking about barfing it up if that were to happen, ha ha. I don't eat anything so its all liquid if it were to happen.
