grand houdini

It starts out when a man is fucking a girl from behind, while she is facing out a window. Another man sneaks out from a nearby hiding place. Man 1 quickly pulls out while Man 2 quickly jumps in. Man 1 sneaks out, runs outside, and waves up to the unsuspecting girl at the window.

Spencer and I totally nailed that grand houdini!
