How many women here, and be honest,can suck cock with enthusiasm for an entire hour? Also let's assume the the guy pops at least once prior to the hour and you just keep going? That means you either swallow or just let the load ooze out whIle you keep that mouth on his cocktail til the hour is up.

There certainly isn't any go in the equation.
