The owner of the world's first sex doll brothel says he is resisting demands for child sex dolls and rape fantasy scenarios from disturbed customers. Sergi Prieto, co-founder of LumiDolls in Barcelona, is proud his brothel can offer punters a wide range of services with any of their four silicon working girls - but thinks some requests are just unacceptable. LumiDolls' website has a picture of one of the 'women' in school uniform and claims schoolgirl is one of the most popular fetishes". But every ethical businessman has to draw a line somewhere - and for Pietro, it is an obvious one. He said: "Some customers prefer the service because they have a rape fantasy. Obviously we don't want to promote this kind of activity." Likewise, he acknowledged a sickening demand for child sex dolls, which were recently outlawed in Britain, where a couple of men have already been convicted of importing them. "In this market there are lots of suppliers that sell dolls that look like children. There exist dolls that are small and look like children," Prieto [said]. "That's an ethical option for us not to provide this kind of service. We could do that, but we don't want to promote this kind of behaviour." Some academics have controversially argued that child sex dolls could be used to prevent paedophiles from attacking real children.
