Drop the beat — and the booty.

Australia’s DJ Flume brought up the rear at the Burning Man gathering this weekend, as an NSFW viral video shows. The 27-year-old producer’s rumored girlfriend, Paige Elkington, 31, posted an Instagram Story of him performing oral sex live on stage at the desert happening.

“Sorry mom,” Elkington, a model and actress, captioned the seconds-long clip of her dancing in a purple wig — with her rear end in the face of Flume, whose real name is Harley Streten.

The clip, since deleted from Elkington’s Instagram, was sandwiched between one of a sign held up at the show reading “Does Flume even eat ass” — which was captioned “Lol wait for next story” — and a video of “The Man” burning, the climax of the 33rd annual event.

The woman who made the sign tells Pedestrian.TV she brought it to performances all week — but got the best reaction from Flume. “We made a whiteboard totem, because we thought it would be fun to write notes and heckle DJs, because it’s Burning Man,” she says, adding that she got Flume to perform additional NSFW acts with it.

Elkington, who has over 90,000 Instagram followers, sells temporary tattoos on her online store and became a meme in 2018 after a photo of her and Jeff Goldbum went viral. Her most recent Instagram post is of a temporary leg tattoo with extensive text about the social media network not having permission to share her photos or messages. Flume became a name on the electronic music scene in 2011 with his single “Possum,” and has since risen to international acclaim. The two appear to have spent time together on Flume’s recently completed tour of Asia.

Burners were largely upset by the use of tech to document the act, as phone use is intensely discouraged and the internet largely unavailable during the nine-day event in Nevada’s remote Black Rock Desert.

“Put your phone away and def don’t film your fav dj having a fun consensual moment with their s/o [significant other],” one person tweeted.

“Whoever put Flume on blast with those videos sucks at Burning Man. It goes against the entire ethos of the event to film someone wildin out like that,” wrote one critic, before recanting when he realized Elkington posted the video.

The spirit of the more than 70,000-person gathering is strongly against Instagram culture. Using the event’s art for promotional purposes is strictly banned.

“Gone to Black Rock City. Putting our devices down. Disconnecting from social media,” reads the Burning Man Project’s pinned tweet, referring to the name of the temporary city where the event takes place.

Still, some commenters were supportive of the video’s sex-positive nature, some saying the act inspired them to attend the gathering next year. Others even went so far as to declare DJ FLume “a legend.”

“[If] that’s not relationship goals idk [I don’t know],” responded one fan.
