In 2003 the world population was approximately 6.3 billion people, of which 49.5% were men for a total of 3,118,500,000 men. How about rounding them all up for an all world bukkake?

If each man spent 5 seconds busting a nut, that's a total of about 494.43 years of cumshots. We can have the guys go 6 at a time and that'll total about 82.4 years.

If you get a girl who's 18, she'll be cummed on over and over by six guys until she's 100+ years old. Unfortunately the schedule does not allow for breaks for sleep, meals, sickness, deaths in the family, etc...

I wonder how long until she's doing the backstroke in an olympic swimming pool?
