It lasts longer than your average joe or orgasms and you don't think it'll ever stop. It's almost like you black out and go to a different world for that period of time. Sometimes you cry after. Your whole body is tense and relaxed at the same time. And you feel like a teenager again because you don't want to stop. It's. That. Good.
