The world’s first sex doll brothel has been bombarded with sick requests from perverts who want to act out rape fantasies and even paedophile abuse.

Owner Sergi Prieto boasts he “caters for all” preferences but he has been forced to turn some people away because of their disturbing desires.

Sergi co-founded the Lumidolls bordello, which opened in Barcelona earlier this year offering to fulfil men’s “wildest fantasies” with lifelike sex dolls from $89 a session.

He told the Daily Star Online “business is booming” as tourists flock there from all over the world — but some vile requests have got out of hand.

Sergi, 72, said: “Some customers prefer the service because they have a rape fantasy.

“Obviously we don’t want to promote this kind of activity.”

He added sickening sex dolls designed to resemble children are also in demand.

He said: “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.

“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 behavior.”

Some campaigners have claimed sex dolls and robots can be used to treat paedophiles who have urges to molest real children.

But this idea was rejected by University of Sheffield AI expert Prof Noel Sharkey, who has called for a ban on child sex dolls entering the UK.

He said in a recent report from Foundation for Responsible Robotics that guilt free sex with a submissive doll or robot could encourage the objectification of women, abuse, rape and paedophilia.

Lumidolls first opened close to the tourist hot spot Las Ramblas but was forced to move after protests from locals.

Its secret location elsewhere in the city is only revealed to paying customers who get in touch online.

Visitors are welcomed into a candlelit room where they can watch pornography with the doll for a “unique experience.”

The company says: “With Lumidolls, customers can perform any of their sexual fantasies they do not dare to do with a woman.

“Tell us how you want to encounter your doll, what kind of clothes you want her to wear and in what position she should be.”

Sergi has plans to expand the business worldwide and could set up a robot sex doll brothel in the UK.
