This is great! Excellent work by all those able to keep tabs. We are on track to finally start determining some type of ranking system for our favorite gokkun queens.
But another thing that needs to be strongly considered in some way- and I'm trying to find a good term, but for now let's say "cum swallow rate" i.e a lot of cum gets wasted, sometimes through no real fault of the actress, but nevertheless.
For example, Marica Hase (sp.?) is as enthusiastic as they come but I eventually became frustrated by the amount of cum that fell by the way side during her scenes. Some was due to how fast it was coming at her so again, not entirely her fault.
So if a cum shot went directly into the girl's mouth and not a single drop was wasted then that would equal a 1.00 CSR (cum swallow rate). 1.00 for a career of gokkun would practically be unheard of if not impossible due to many factors, but obviously the higher CSR the better. I think Megumi's would be among the highest in my opinion, maybe 0.90 or better.
This is something that of course would be fairly subjective where reasonable people could disagree but for starters I don't think someone like Marica Hase would quite make it into the field based on such a low CSR. I mean, we're talking all time greatest cum swallowing goats. And eventually a tournament of some kind is needed as I've mentioned in this thread before.
If she's swallowed another 100 that will put her into third place!
