Men on a beach in Rio de Janeiro thought all their Christmases have come at once when this woman asked them to rub suncream on her back.
But the bikini-wearing sunseeker wiped the smile off their faces when she turned over so they rub sunscreen into her stomach.
Brazilian YouTube joker David Mafra enlisted the help of the female actress, who stuffed a fake penis down her skimpy bikini bottoms before stretching out face-down on the sand and inviting strangers walking past her to help apply suncream.
All oblige at first – with a couple even trying to chat her up as they runs their hands over her body.
But the men get a lot more than they bargained for after the woman turned over and showed off her ‘bulge’.
The footage – titled ‘Fake Balls Prank’ or ‘Bolas falsas’ in Portuguese – has already been seen by nearly 1.75 million people .
Ingrid Ohara, a regular on another Brazilian practical jokes programme, tells viewers with a mischievous smile on her face: “Today, I’ll pretend I have…a dong” before making herself comfortable under the sun in a tight-fitting bikini.
