GONE are the days of blow-up women with perpetually open mouths - sex dolls are rapidly evolving and becoming more lifelike than ever.

And now a brothel in Dublin is renting out a silicone robot sex doll for £80 an hour.

A bit like a buxom Barbie doll, the blonde android has massive boobs, an hourglass figure and eerily lifelike facial features fixed into a sexy pout.

Described as “Ireland’s most realistic sex doll”, Passion Dolly arrived at the Dublin brothel less than a month ago and dozens of punters have already had their way with her.

Weighing eight stone with 32 E boobs the doll imported from America has a metal skeleton covered in silicone and responds to vibrations moving like a human.

She is being leased out by two Eastern European sex workers who allow men to pay to spend time with her – but not remove her from the premises.

The ad on an adult website reads: “Are you wasting money paying for sex… or watching porn? Why not have the full pleasure of having sex with the most beautiful girl whenever you want and as many times as you want? Passion Dolly is an ultra-realistic sex doll for your pleasure.

“She is made of either TPE or medical silicone and has a metal skeleton as internal structure to allow you to bend and twist the doll’s torso, head, arms and legs to pose in any sexual position you please.”

When customers arrive they will find Dolly - who you can rent for £80 an hour or £40 per half hour – lying on a bed in a dimly lit room.

Condoms and tissues are also provided.

Her owners explained: “We have had her about a month and have had dozens of visitors, mostly Irish men and ranging in all ages.

“Some of them are a bit lonely, a few have social problems interacting with women, while others have a fascination with dolls.”

In a recent report, the Foundation for Responsible Robotics said that android love dolls will become increasingly common over the next 10 years.

Some scientists have even warned that there is a danger that the ‘pleasure-bots’ could lead to a decrease in real human relationships.

They could also lead to the objectification of children and women and could encourage abuse, rape and paedophilia.

However, they also claimed they could provide help for people who find it hard to have intimate relationships – like those in care homes, and people with dementia or disabilities.

The foundation also estimate that it will take take another 50 years before sex dolls are able to move, talk spontaneously and have facial expressions that look truly human.

In other words, we won’t be bedding with the creepily real androids in the hit Channel 4 show Humans any time in the near future.

There are currently five makers of sex robots worldwide, with prices ranging from £4,000 to more than £12,000 for a ‘deluxe’ model.

A recent U.S. survey of 100 people found that two-thirds of males aged 20-61 would have sex with a robot, compared with a third of women.

But experts claim politicians and the public need to deal with the ethical issues that sex robots will pose to society and relationships.

Belfast-born Noel Sharkey, a professor of artificial intelligence and robotics at the University of Sheffield, and Dr Aimee van Wynsberghe, assistant professor in ethics and technology at a Dutch university, said governments need to introduce legislation to stop abuses of this technology.

“Some say it’s better to rape a robot than a person, but others think it would encourage rape,” states Noel.

He also wants to see the government take pre-emptive action to stop paedophile sex robots entering Britain.

He said there should be a “ban” on importing those.
