When a grandmother noticed a couple "bumping uglies" on a public beach, she pulled out her cell phone and started recording.

Usually, when you say "sex on the beach" it may be referring to a shot at the bar -- but in the case of one Florida couple, the meaning was as literal as can be.

A grandmother from Bradenton Beach, Florida was trying to enjoy her time with her family and grandkids on the beach. She got upset when she noticed a couple "enjoying" themselves on the beach, so she recorded them in action, then called the cops.

According to FOX 13, the couple had sex on the beach for about 25 minutes, jumped in the water, then returned for more lewd behavior in the sand after passing out for hours.

The cops eventually arrested the couple and charged them with lewd and lascivious behavior.
