A three-way with two women in the same bloodline at least one generation apart. Either a mom and daughter, or or if you're really daring, a mother-grandmother would fulfill this life long dream.
Man, you won't believe what happened-I was riding this chick and her mom walked in the room and joined in for a 3-way! I had a 3-2G! My friend said he had a 3-2G many years ago but the two women who claimed to be mom and daughter are probably still laughing to this day about the guy who thought he had a 3-2G.
