Loved doing this when I was younger. I would save up until I knew it would go off like a fire hose and roll over with the head an inch or two from my open mouth. You could watch it swell up and turn angry red. The precum would already be dripping. Then you could watch it spurting and know you would get a big warm mouthful to swallow. I had a pretty teenage girlfriend who liked to stroke and aim it for me and she always got it right in, Yummmm
