I have found a coupl'a ladies who dribble copious amounts; but no actual 'fountains' per se, yet - my goal in life is to find a veritable gusher (Bucket [or better, F++++t] List item!)
Ya gotta laff, tho'. Having spent some 20 minutes slurping up 'Lady Juice', they usually ask 'you want wahtah?' as a parting gift !! to which I usually reply 'no thanks, I'm good!'
