Like the Effiel Tower, a girl is giving head to a guy and also recieving anal sex, but she is also giving two guys handjobs and all of this is going on at the same time; the four guys all connect their hands over the girl, making a point just like the Empire State Building.
Eoj-"Hey man! This girl that my buddy and I met at this party...we Effiel Towered her. Yeah!"
Nerrad-"Well, my three friends and I did a Empire State Building with this random girl from a party. Yeah! I think I win."
Eoj-"Wow, that's amazing!"
