An extreme case of PDA ended with the arrest of a couple who police said had sex in broad daylight in the ocean.

Matthew McPeak, 27, and Stephanie Wallington, 23, both of Philadelphia, were arrested after they allegedly had sex in the ocean near the 46th Street beach in Sea Isle City.

Investigators say the public romp took place shortly after 4 p.m. on Sunday. According to Mike Geraghty, of Lower Merion, a crowd of about 30 onlookers formed as the duo went at it, seemingly oblivious to their audience on the beach.

"They appeared to be heavily intoxicated," said Geraghty. "When police arrived they were pretty confused."

Both McPeak and Wallington were directed out of the water by responding police officers and taken into custody.

They were eventually charged with lewdness and released on a summons.
