A sexual position in which the female has her shoulders on the ground, ass in the air, and her partner penetrates her by approaching from the back and holding her legs in front of him/her, thus replicating the use of a fifth wheel trailer and a truck
Holy shit, did you see that porn star get fifth wheeled in that video? Her shoulders must be hurting!
