As far as the biggest I'VE ever shot, there are just too many to recall since I'm a shooter to begin with. Sometimes it flows out, but usually it flies. Holding out for days or weeks always makes it huge, but that's a pretty a pretty brutal denial of pleasure. One that stands out in my mind was when I was 16 and just gotten my first car. I knew a month ahead of time the day I would get it, so I didn't cum for a month, maybe even a few days longer. It was almost impossible to sleep or function normally, and since my birthday is in August school wasn't a convenient distraction. With my nasal allergies acting up, everytime I sneezed I excpected cum to fly out of my nose! Somehow I made it to the big day. My intention was to baptize the car with my cum, marking my territory. My parents were gone for the day, and it was hot and sunny, so I washed the car in wearing only my skimpy swim trunks, my cock dancing around. The back of our house was secluded, so nobody could see. When I finished rinsing the car off, I stood over the low hood (it was a Fiat X/19) and beat off. Standing there in the hot sun stroking away with Hawaiian Tropic oil was pure bliss. I lasted about 5 minutes and came an insane amount all over the hood. It flew up about eye level and splattered all over, making loud "splat" sounds as it landed. I just screamed and swore and cried out, I didn't care at that moment if 1000 people were watching. It felt like it lasted for hours it was so intense. My legs were weak and I had to sit for a bit after. I counted 42 globs of cum, tiny to big and tasty. Since the car was clean, I wiped it up with my fingers and ate it. I'm a vegetarian, so my cum is extra tasty and never bitter. That night I sat in the car and beat off again, this time the load seemed just as big, but I let it dry naturally where it landed. Whether it was at home or somewhere else, jerking in the car became a habit, sometimes with a toy or vibrator up my ass.
As far as loads I've seen shot that you can watch too, at xtube.com check out the videos of "trotlikeahorse", this black dude with a perfect dick that had a head you want to suck on all day. He has 21 videos and blasts some serious loud loads, I've jerked to a shattering orgasm to all of them. Hearing his shots land on a hardwood floor makes me drool!
