While shoving 4-5 vodka soaked tennis balls up her twat. The Russian Tennis Geyser is performed when the woman in question increases pressure in her snatch by preparing to queef, then letting it all explode out at once. There are only 5 known casualties that were sacrificed in the making of this technique. This is generally very dangerous and should not be attempted unless you are a professional whore.
