The Internet went crazy over a viral video of gorillas performing oral sex at Bronx Zoo in New York City.

A Gorilla, in front of humans including kids, casually started to perform oral sex on another that visibly left the visitors horrified.

The video, which was filmed Wednesday, shows one gorilla lying on its back as another pleasure it.

Some parents immediately moved to hide the eyes of their children while some immediately got away with their children from the amorous gorillas.

The videographer behind the clip told the New York Post that he was visiting the gorilla exhibit with his 4-year-old daughter and his niece.

He said that “My wife had to stay out of the exhibit with my sleeping son, so I wanted to capture a lot of videos.”

“Then this magic happened,” he added.

The gorillas pleasuring each other, however, is not the first of its kind ever recorded. Around seven years ago, a Reddit user posted a pic of two other gorillas pleasuring each other at the same zoo. Animals including fruit bats, goats, brown bears, hyenas, and lions have all been reported to perform oral sex, according to a 2014 BBC article.
