BRADENTON BEACH, Fla. (PIX11) — An outraged grandmother whipped out her cellphone after she spotted a couple having sex on a public Florida beach — in full view of children.

The grandmother, who did not want to show her face, told FOX 13 the raunchy couple starting going at it on Bradenton Beach in front of dozens of people.

The pair, identified as Jose “Benny” Caballero and Elissa Alvarez, kept going for about 25 minutes before taking a dip in the ocean.

She threatened to turn the video over to the cops if they didn’t stop, but they were not fazed.

“(Afterwards), they laid on the beach and passed out for hours. We thought they were dead, but when they woke up, they cuddled for a while, then started into the same thing they did before,” the woman said.

A fed-up parent eventually called police, and Caballero and Alvarez were arrested and charged with lewd and lascivious behavior.

“I’ve lived here since 1978 and I go to the beaches and I’ve never seen anything like this,”the grandmother told the station.
