Pelican Swirl
One girl squats, 1 dude lays on the ground below her ass hole. Another dude cums inside the mouth of the guy laying down, and then she shits in the mouth of the guy laying down. Cum mixing with shit is bird poop. "Laying the mongoose" The guy laying down also flaps his arms like a bird the whole time.
"I just had sex with a girl and a guy in a threesome. We tried this Pelican Swirl move where she shits in my mouth and he cums in my mouth.
