A randy couple are facing jail for allegedly making a series of explicit public porno films including one in a Burger King.

Police in Louisiana say they discovered images which suggest the pair filmed graphic scenes inside a public library, supermarket and the popular fast food restaurant.

The Smoking Gun reports the married couple are now facing obscenity charges — which could lead to a jail term.

Investigators said they received a “report of lewd activity that occurred within a public library” in Houma.

It is claimed by local police that they suspects “recorded themselves performing sexual activities on each other and uploaded them to a porn site.”

Looking into the case, it is said the pair in the sordid videos are Elizabeth Jernigan, 33, and her husband Rex, 35.

Investigators forced themselves to have a good long look at the couple’s PornHub page and found it was packed with over 160 explicit videos.

Officers told the investigative website that the Jernigans recorded themselves engaged in sexual activity “in various other businesses throughout the City of Houma and Terrebonne Parish.”

They said the PornHub videos seem to show the wife exposing herself and masturbating inside various businesses at the Southland Mall in Houma including a Burger King.

The public library video includes similar explicit exploits and concludes with Elizabeth performing oral sex on her husband in front of a magazine rack.

The Jernigans are now each charged with six counts of obscenity.

Rex later shared this news on the couple’s PornHub page after their release on bail.

Under his pseudonym Sexybeast82, he wrote: “To all my friends and followers, the wife and I just recently bailed out of jail for our public videos we posted on pornhub, hopefully soon we’ll get to post a new video soon.” His wife is known as LaylaDevine.

The couple’s PornHub page has 4,187 subscribers and its videos have been viewed more than 1.7 million times.
