I cannot judge unless I've seen all entrants in action. This sounds like an OOE - Oral Olympic Event. Three winners get gold, silver, or bronze medals to dangle off their tongues, or lower for the ladies to compete and complete.
Hmmm...no stealing my idea. I see an ad waiting to be created.
We talking tongue to clit stimulation? Deepest tongue penetration? Most stamina? Best hands free technique? Or the chowing down on a juicy peach award?
Years ago I attended a bachelor party. The entertainers were two ladies known then as "The Salad Sisters". On of the entertainment items of the night was a DATY contest. Each contestant performed DATY on each sister. The sisters then voted on best DATY performer. Yours truly won the contest hands down! Or should I say "tongue out"?
