San Fransisco Surprise

The act of getting your unassuming partner in the mood and then having a friend come into the room unannounced, bare ass naked, sportin' a raging boner and ready to shag as if it's just no big deal at all.

Daniel- "I've got something for ya baby. How about a little San Fransisco Surprise?"
Totally Hot Chick- "Fuck yes! I want it now Danny!"
Daniel- "All right love. Turn around and let me give it to you."

Daniel's friend, as he walks into the room unannounced, naked and sportin a throbbing hardon - "Oh, hey guys. Mind if I join?"
