What is Surprise Shot?
1.
Before encourse begins the girl states that she would not like to be blasted with the man's load on her face but rather her back. So the sneaky man, while"railing" her from behind, acts as if he is about to ejaculate but rather spits on the girls back, creating the illusion of cum; once the girl turns around the man unleases the load onto her face giving her the "surprise shot."
