Missouri Arch

This is a sex position involving 3 people. A male stands up, legs slightly spread in an arch, and two others stand, sucking on his cock and anus. The man starts shitting and the partner sucking the anus eats it while jacking off the standing man, meanwhile the partner sucking the cock gives him a sick BJ.

Jim: "Just got a Missouri arch from Carla and Dayna the other day"
Kevin: "WHO THE HELL CARES? THAT IS DISGUSTING! GET OUT!"
