This term pertains to a sexual position involving two males and a female. Normally the female will be a slut but there have been cases reported where she is just a damn good sport. The two males sit on a bed facing each other with their legs spread wide and raised slightly in the air. If they two males wish they may touch feet to make it easier to keep their legs at a slight angle. The female then lowers herself onto the crotchal region of one male while still facing the other. As she lifts her vaginal region off of male number one she lowers her mouth to fellate the male she was originally facing. This movement is repeated as many times as necessary. Thus the female is making a sort of see-saw or oil rig-esque motion. To bring this image to the next level one can almost say that like an oil rig she is sucking the "oil" from the depths of the well. If the two consenting gentlemen see fit, they may intertwine each others toes for a small bit of added pleasure during the orgasmic moments.
