When you get a group of 5 or more women together who are hot for your cock and make them fight for it simultaneously until they get every last drop of your tasty treats. (similar to Koi fish fighting for bread cumbs.)
Hey girls, would you like to participate in a Koi Pond? - Girls: "What's that?" - I'm glad you asked!
