A frisky couple were caught on camera in China sneaking into a portable toilet for a secret romp, only for the wall to collapse and the pair to come crashing through.

A man and a woman were seen walking through what appears to be a construction site, making a beeline for a portaloo located opposite a prefab office.

The woman opens the door and takes a look, before following the man inside. 

Moments later, a side wall breaks and the woman falls out into the dirt.

The man can be seen trying to grab her as she falls, and then leaving through the door and walking round to help her up.

Left red-faced, the duo appear to flee the scene. 

The footage is understood to have been filmed in the Chinese city of Jingzhou.
