This is the brazen moment a randy couple is filmed having sex in a lake in broad daylight just feet away from groups of tourists trying to enjoy their day by the water.

The lewd act was filmed by a day tripper on the reservoir lake in the city of Palmas (population 306,296), which is the capital of the Brazilian state of Tocantins.

The video, filmed on an unspecified date this month (September), went viral on Brazilian social media over the weekend (18th-19th September).

The act was made all the more shameless by the fact it took place alongside a boat on which tourists likely including children were enjoying a day out on the lake.

In the recording, people can be seen stood on the boat just feet away from where the couple is uninhibitedly having sex.

According to news site G1, it is the second such occurrence registered on the lake this month.

In the earlier incident, a couple was filmed having sex on the top deck of a boat while other tourists and day trippers were on the deck beneath them.

The lewd act also took place in broad daylight and was clearly seen by day trippers on another boat.

Committing an “obscene act” in public is a crime in Brazil and carries a penalty of three months to a year in prison or a fine.

Boat trips on the lake in Palmas are a popular past time and are currently permitted, but guests must adhere to rules to stop the spread of COVID-19.

No police report was filed over the latest incident.
