In Albufeira, Portugal, on the Av. Sá Carneiro, Twitter user George Fuller noticed a man on his knees with his head poking up a woman’s skirt.

He instantly started filming the man moving his head up and down while engaging in oral sex with the woman whose legs were draped over his shoulders.

The man knelt down on the pavement underneath the woman who appeared to be perched on a ledge in front of a mobile phone repair shop.

The couple didn’t seem disturbed at all as they continued in full view of Fuller and his pals.

Fuller shared the video on Twitter and it has now gone viral.
