The footage shows the reality star enjoying himself as the male, whose face is never shown on screen, reclines face-down on a kitchen bench top, with his micro-mini kilt pulled down to expose his bottom cleft.
Ciarran appears to snort something from the man’s backside and then elicits cheers by taking a good sniff of the man’s rear cleavage.
The emergence of the video follows a string of images appearing from the performer’s days as a part of the racy stage show at Darwin gay club, Throb.
Shocking photos emerged from Ciarran's past showing the future reality star stripping in Darwin's popular gay nightclub, Throb— a raunchy establishment where he's said to have regularly performed at.
According to StarNow, Ciarran is an ‘actor, extra and model.’
Although he's already planted himself as a fan favourite on this season of the hit dating series, an insider recently told The Daily Mail that the Englishman might not be looking for love after all.
A source close Ciarran recently told the outlet that he applied for the show after hearing that his ex-girlfriend, Renne Barrett, was going to star on Matt Agnew's season of The Bachelor.
"As soon as he found out she'd been cast on Matt's season and was about to start filming, he decided to get on The Bachelorette," the insider dished.
"Casting producers were aware of this and it definitely helped his cause. His friends are saying he mostly went on to get back at Renee."
While it's unclear whether all of this will come to light during the show, we needn't worry too much seeing as the source said Ciarran doesn't receive the final rose.
