A sex position derived from the infamous Eiffel Tower, in which two males and two females engage in sexual intercourse. It is identical to the original Eiffel Tower, except that the second girl is face down with her legs resting on the shoulders of one guy and her arms supporting her on the back of the other girl. This girl has her pussy eaten out while she makes out with the other guy. And the girl below her, blows one guy while she is fucked by the other.
"Hey Spencer! Do you want to double helix (sex position) Gabrielle and Grace tonight?"

"Definitely, Kyle. I'll make out with grace and fuck Gabrielle. You eat out grace and get blown by Gabrielle!"

"It's gonna be fucking legendary!"

"Hell yah!"
