A naked couple fell to their deaths while having sex on a third-floor balcony after a house party in Ecuador.

The man, 35, and woman, 28, reportedly fell over the edge of the balcony at a property in Carapungo, a neighbourhood in Ecuador’s capital city, Quito.

Calderon Police district operations chief Christhian Trujilo told local reporters the couple had thrown a party with friends at home to celebrate the female victim’s imminent graduation.

After the party, the couple went to have sex on the balcony before falling three storeys to a neighbour’s terrace where their bodies were discovered.

The neighbour who found them apparently heard an unusual noise seconds earlier and went out to investigation.

A heartbroken relative of the female victim told reporters that the deceased woman was the mother of an eight-year-old girl, and local authorities are investigating the deaths.
