The Next Best Thing Experience

[Next Best Thing]

and how do you keep driving if you're controlling your flow and spilling out the bottle? You cant say your knees cause you'll end up peeing allover the seat, i've tried that.

You have to develop a feel for when the bottle is becoming full. With plastic bottles it's easy, your hand starts to get warm as the bottle becomes full. With glass (like a Snapple bottle), you have to sneak a peak.

This is impossible to do with even the slightest hint of a hardon.
