[HELP] Magic perfume

Magic perfume producing sex partners for piss orgies

My mom rented this porn VHS thinking it was a romance some 30y ago that featured couples who went at this hotel or brothel like building where a person would give them a special perfume that if spilled would make appear a partner, male or female, for steamy threesomes involving lots of pissing action. The storyline is somewhat similar to the movie Liquid Love from 1988. I would appreciate any help in finding this title as it is a dear chiⅼdhood memory
