A man and a woman were spotted engaging in sexual acts along Nathan Road in the wee hours of Thursday (March 15), slightly after midnight.

Stomper Zai, who submitted photos and videos to Stomp, had just dropped off a passenger and was waiting to pick up someone else when he saw the couple at around 12.30am .

He told Stomp: "I drove past a lane in Nathan Road and surprisingly, saw a couple having sex by the side of the road, opposite Fraser Suites.

"The woman was naked and the guy was caressing her.

"Moments later, the lady performed a sex act on him openly in public.

"Honestly, it went on for like 45 minutes, throughout the whole time while I was waiting for my passenger (who turned out to be a no-show).

"The couple ignored passers-by who took photos of them.

"When I asked them what they were doing, the woman told me to 'f**k off'.

"What a life, yeah?"

In the two videos contributed by Zai, lasting five and a half minutes in total, the couple can be seen kissing and having sex.

The woman was also topless.

Stomp revisited the scene earlier this afternoon at around 4pm.

The aforementioned location of the incident is also near Brighton Montessori, a pre-school, along River Valley Road.

Besides the school's signboard, other giveaway signs are the metal railings that the woman can be seen grabbing and a large decal on the glass display.

Stomp will not be uploading the videos due to their obscene nature.
