Cowboy Freight Train

When a group of men engage in the act of standing in a line with a person both in front of them and behind them; as the line starts to progress across an area all the men involved simultaneously insert their penis into the anus of the man in front of them, place their hands on the shoulders of the man in front of them, and walk, dance, and thrust to the rhythm of the music that is playing. Rules: 1) Making train noises with your mouth is encouraged but not required. 2) Women with strap-ons are allowed to participate depending on who is taking part, but it is always looked down upon.
