See "double anal tug"

A sexual act in which two women (or men, whatever the preference) simultaneously jerk off an erect male using both of their asses with the penis in between the four ass cheeks, long-ways along both ass cracks.
Being the booty lover that he is, Stan likes to get a couple of big assed girls, oil up their thick booties, and get them to jerk him off using the ol' double assturbation technique.
