As the pair left the club, they were each allegedly handed a copy of their sex tape.
Adam Randall, 36, appeared in the Melbourne Magistrates Court accused of sexually abusing the teenager for over three years from when the boy was 13.
Randall faced a total of 14 charges, including having unprotected sex with the boy and another man on separate occasions without telling them he had HIV, putting them at risk of getting the disease.
Magistrate Elizabeth Lambden committed Randall to stand trial in the County Court on eight of the charges - two counts of reckless conduct endangering serious injury; making child pornography by filming the boy at the Collingwood sex club; taking photographs of the boy engaging in indecent sexual acts; sexually penetrating a child under 16; taking part in an indecent act with a child; sexually abusing the boy from more than three years from January 1, 2008 and October 1, 2011; and soliciting a child under 16 to take part in an act of sexual penetration.
Randall, who pleaded not guilty to the charges, will appear in the County Court on December 3 for a directions hearing.
He is expected to plead guilty to the six remaining, less serious charges this afternoon in the Magistrates Court.
These charges include working as a sex worker while infected with HIV; operating a brothel at his home without a permit or licence for more than seven years from January 1, 2005, to May 23 this year; possessing cannabis; displaying a false advertisement for sex work; and unlawful assault.
Police told the court at an earlier hearing that officers had first contacted Randall after receiving an anonymous tip-off that he was advertising sexual services in the Melbourne Community Voice.
Police arranged to meet Randall at his home on May 23 where he allegedly agreed to have unprotected sex after claiming he was clean.
He was arrested and police seized a diary which had a list of his clients' names, dates and the dollar amounts that they had paid.
When questioned at Epping police station, Randall denied having unprotected sex with clients.
Police said Randall claimed he had a high sex drive and usually went to a sauna in Collingwood where he would have sex with up to 20 strangers a day but always wore a condom.
Randall allegedly knew he should not be working as an escort because he was HIV positive.
He was later released on strict bail conditions including that he live with his mother in Warburton and accept a Department of Health order that he not engage in any form of sex work, advise all his sex partners of his HIV status before having sex, and have safe sex.
