Randy couple caught on camera romping on motorway bridge in daylight aren't put off by pouring rain

WARNING: Graphic images. The lovers were spotted in a compromising position by a passer-by trying to cross the bridge who stopped to film them having sex

Despite the heavy rain, the couple were seen sprawled on the wet concrete as they rolled around and 'enjoyed' each other's company.

They were apparently so wrapped up in the moment they seemed to forget they were being drenched by monsoon rains lashing the area.

And they failed to spot onlooker Adisak Khaosaard who walked up the steps to find the pair passionately kissing.

Adisak, 29, filmed the pair from both sides of the motorway bridge after catching them in the act.

Police officers are now hunting the pair after the video recorded in Rayong, Thailand, was shared across social media.
