THIS is the moment a randy couple put on a live sex show from their hotel room balcony as onlookers filmed their romp from the street.

The pair appeared to forget to turn off the lights in their hotel room in the Russian port city of Novorossiysk on the Black Sea.''

The scene from the hotel balcony left little to the imagination as the frisky pair's outlines were visible against the room's bright lights to passersby below.

As the couple cavorted, an eyewitness filmed the romp as other onlookers are heard whistling and cheering.

The clip has since gone viral since it was posted online, as some people have pointed out that the couple might have been in serious trouble had they attempted something similar in the days of the Soviet Union.

But others felt the couple had done nothing wrong.

Netizen EXinkvizitor said: "Seriously, why would people look at balconies?

"These people did not have sex on the pavement, so what's the deal here?!"

User Postalm3x agreed, adding: "I think everything is fine, those two were simply working on improving the demographic situation in our country."

And 'valerobus' noted: "The weather has been hot the last couple of weeks.

"On the balcony you can get some breeze, people are admiring you with their exclamations. I think it is very romantic."
