A man has been caught on camera having sex with the road in the middle of the day.

Stunned office workers filmed the man thrusting his bare hips into the ground outside their building in Long Beach, California.

The footage shows a second man crouching on all fours beside a van and watching the disturbing scenes from close range.

‘This is what we’ve come to work to this morning, this little ground sex session going on just outside the window’ a man says in the vision.

‘His friend there is checking him out…What is he doing?’ asks another man in the office.

The bizarre vision was uploaded to Reddit this week, where it has drawn a range of bewildered comments.

‘Was it wet concrete? How could this happen?’ wrote one commenter.

‘Boy, this was a little more HD than it really needed to be,’ wrote another.

‘What was that guy near him doing and where did he go, that's what I'm interested in’ another user posted.
