1.) Also called "anal train", "three-way butt-fuck" or "French Sandwich"; It is a sexual position where, as the name implies—Roman numeral three is written as "III" instead of the typical Arabic "3"—three partners engage in anal sex. The first partner assumes the bottom position. A second partner—penetrates the bottom— assumes the Lucky Pierre position, as he himself is penetrated by a third partner. The Roman Three is a specific designation of the anal train. An anal train is not limited to three, and can consist of a fourth, fifth or sixth partner(s), etc.
1.) Let's do a Roman Three now!
2.) Man, last night, Mike, Edwin and I, had a threesome, we first did a 369, then a Roman Three. I got to be the Lucky Pierre! You know, the ham of the sandwich.
