Oral sex and Verbiage.

Some people are of the opinion that a good method of performing cunnilingus is to do it while silently pronouncing certain words. "Mississippi-Leather" and things like that. While this is not a guaranteed tried and true scientific method...as we all have our preferences when receiving oral service, but if nothing else I would suggest saying "Pneumonoultramicroscopicsilicovolcanokoniosis" as-fast-as-you-can...about 300 times and see how that goes.  :)
