Cleopatra's Pyramid

In a FMF threesome, when a guy lays on his back and has one girl straddling/riding his lap and the other his face, therefor creating a trifecta of awesome. Essentially, it is the sister sexual act to the fingercuff.

Craziest thing happened last night, I took two girls home and they had me at the bottom of a Cleopatra's Pyramid!
