The unverified clip was supposedly filmed in the Spanish resort of Benidorm '“Â popular with Brit sunseekers '“Â and shows a woman performing a sex act on a man at the side of her as the pair recline on sun-loungers.
The outrageous behaviour continues for 46 seconds before the filming stops '“Â despite the fact there's another holidaymaker on the sun lounger right next to them.
The incident, which has been widely circulated on Twitter and Facebook, shows other holidaymakers just a few feet away as the sordid antics take place.
The woman, wearing a bathing suit and the man, wearing swimming trunks are seen in the clip entitledÂ "Meanwhile in Benidorm."
On Twitter, one shocked viewerÂ wrote: "Looks like it ain't the first time they've done this look how calm he is."
Another said: "Thanks... can I send you my therapy bill for that horrific scene? I'll never get that out of my head!"
