The Chugga Train is a sexual position that requires at least 3 men. The man in the front will take it up the ass while jerking off saying “Choo Choo.” The men in the middle will both give and receive will swinging their arms in a circular motion. The man in the back, or the caboose, will be in charge of making sure the “train” keeps moving.
The 4 men decided to try the Chugga Train tonight.
