A group of four engaged in a full-blown orgy at a park beneath Cardiff Castle in Wales just a few feet from where children played nearby.
Photos show the explicit foursome, which included a fully nude woman having sex with at least one of the men involved, taking place in broad daylight.
A woman who chose not to be named caught the brazen party in the act while walking home from work.
The witness said the romp, which she initially mistook for a picnic, was taking place in Bute Park at around 5pm yesterday.
It happened under a tree near a public footpath frequented by dog-walkers, showing those who participated had no care for hiding or keeping their sordid affair secret.
'As I was walking past the castle, I could just see over the wall and seen two couples enjoying a picnic.
'It looked as though one of the women was scratching her crotch quite a lot. So, I looked a little closer and I realised what she was actually doing.'
She described seeing a man exposing his genitalia and another woman engaging in what appeared to be sexual activity with another female.
'It then clicked that something very strange was going on.
'I felt like a rabbit in the headlights - I was frozen and couldn't stop watching.
'I looked around and there was only one or two other people who could see and were taking photos.
'I took a cheeky snap because I knew people wouldn't believe me.'
The woman said she looked for a police officer to inform them about the incident because there were 'plenty of children around'.
But as she made her way back to her car for a second time, she 'obviously had another look'.
'This time they where all having full on sex.'
Cardiff Council reported the incident and South Wales Police are aware.
