A sexual position involving 3 persons in which 2 are male and 1 is female. This position most similarly represents the “Eiffel Tower”, while the female presents herself to perform fellatio on one male whilst being penetrated by the other from behind. She will then be spun by both males such that she resembles a roticery chicken being cooked / steamed. This, this ambitious position has coined the phrase the “twin screw steamer”

Aragorn, Legolas and Mrs. Gamgee had a great twin screw steamer last night. Too bad she got so dizzy!
