the act in which two men start by getting on their backs,then proceed to get butt to butt, literally so close that these two guys are touching dicks side by side.
thus making it one dick like an "entity".
now the third person male or female now comes into
play,then insert both dicks at the same
time into the
ass or puss.now once on and in position using your hands grabbing the ankles of the other two thus the "buissness
chair" is born now "swivel" yourself about till climax is acheived.
