A man spotted yesterday afternoon performing oral sex on a woman lying down on a Florida beach boardwalk told cops that he was an “emergency responder and had to assist the female as it was his duty,” according to a criminal complaint.

A Treasure Island Police Department officer found Tracy Briley, 50, with his shorts at his ankles and “penis out in plain view” around 1 PM Wednesday. Briley, the cop noted, “was performing cunnilingus on a female subject laying on the beach boardwalk.”

Briley, seen at right, told the officer that he was homeless and “had nowhere else to have sex except in public.”

When Officer Zakariah Dorman arrived on the boardwalk, Briley’s companion--who is not identified in the complaint--was clothed. She was subsequently transported to a local hospital “reference to a medical issue.”
