A sexual act,
irrelevant of
orientation, in which one partner, henceforth referred to as "
The Conductor", performs intense anal sex with the other partner, "The Caboose", to completion.
Upon completion the Conductor removes their phallus from the Caboose's sphincter, which at this point should be sufficiently gaped enough for the arrival of the next train. The Conductor then turns around and sits their buttocks of the Caboose's rear, and proceeds to defacate into the Caboose's gaping "station".
The Caboose will then push the train back into the Conductor's own asshole, and the pair will go back and forth until a second climax is reached, at which point, the climaxing partner will shout "ALL ABOARD!"
"Judy and I got a bit freaky
last night and took a trip down to the ol' Detroit
train station."
"I was feeling a little empty until Bill and I went down to the Detrot
train station last night, now we're both pretty full."
