Eliot Spitzer and his girlfriend, the newly unemployed Lis Smith, put on quite the afternoon sex show for the families staying at the Montego Bay resort in Jamaica this week. And according to onlookers, it was gross.

According to the New York Post, a 10-year-old boy discovered them in a resort hot tub and ran screaming to his parents.

"Mom there's an old guy in the Jacuzzi with this girl and she's topless and she's got her legs wrapped around him," sources said.

The boy's cries — "He's sucking on her toes!" alerted other guests, who walked over to catch an eyeful.

Another witness confirmed Spitzer's footplay fetish.

"He was licking her toes," a witness told the Post. "She would sit in his lap. Then he'd put her feet in his mouth. He licked her toes and was playing with her feet."

But Smith, who brought Spitzer home to meet her parents over Christmas, appears to be into it.
