Photos have surfaced from inside the 1920s California mansion that was allegedly trashed by a gay porn star accused of duping the owner into renting it to him on Airbnb, only to shoot a hardcore adult film inside the home and leave it covered in bodily fluids and scattered with assorted sexual devices.

Obtained exclusively by Daily Mail Online, the images - some taken with a black light - show the 'filthy' Ojai property with semen and urine stains on a variety of surfaces, as well as in the bed and hot tub, where fecal matter was also found, according to the owner.

Disposable enemas were left on a table and in the bathroom, along with hypodermic syringes, lubricant, alcohol wipes and other items believed to have been used in the making of the erotic movie.

The owner of the house, Kristina Knapic, is now suing Andrei Treivas, 43 - a gay porn star, director and producer known professionally as Michael Lucas - for fraud, negligence, trespass, and breach of contract, claiming he rented the property the $1095-a-night property on AirBnB under the fake name 'Anna', saying he was seeking a 'summer vacation'.

However Knapic claims that was all a ruse and that Treivas spent the ensuing five days shooting an adult film all over the house and causing much damage, including breaking beds.

Michael Lucas (right) - real name Andrei Treivas - is being sued by the owner of the Acacia Mansion located in California who alleges he rented the property under false pretenses

The owner of the mansion, Kristina Knapic, 45, alleges that Lucas rented the property under a fake name that looked like 'Anna' and showed up to take the keys by saying he was her brother in law

Instagram and Facebook pictures by Lucas taken from August 12 show him at a house that looks similar to the Acacia Mansion. 'Hello California, this will be an interesting week,' he writes.

Speaking with Daily Mail Online Wednesday, Knapic said the group did not attempt to cover up what had gone on or clean up their mess.

Knapic also said it was the first time she had used Air Bnb, having previously been too wary of trusting temporary guests with her historic house.

'This is meant to be a romantic wedding venue and they came in and defiled it,' Knapic said.

'They left a bunch of testotsterone and needles in the fridge – and then called me asking for them back and were upset when I told him they had been thrown out.'

Testerone, the male sex hormone, can be injected into the penis to improve and maintain erections.

Knapic said that while it was difficult to put a figure on it, she estimated the damage caused to be about $50,000.

'They broke one of the beds, the mattresses are toast and I've had to reject future reservations to clean it,' she said.

'If the next group came in and found used enema kits in the draw the Yelp reviews would finish me.'

However Treivas said Knapic is trying to blame him for damage done by someone else, calling her a 'professional extortionist'.

The pornographer admits using the home to film porn sequences, but said he was within his rights to do so, because the property did not have a clause restricting commercial filming.

Treivas claims he brought in all his own bedding and took out all the trash, and that a man who tends to the house named Dorian walked through the house with him when Treivas and his crew checked out.

'We are a very professional company and the house was spotless,' Treivas told Daily Mail Online.

'It is none of her business what I was doing in her house and I don't feel I had to tell her.'

'She has taken all that garbage out of the trash and put it there. Someone else has damaged her house and she is targeting us because we are in porn. It's a cliche.'

Telling: The owner believed the house had been used for a kinky sex party until finding this business card for New York-based adult film company Lucas Entertainment and started investigating

Knapic said she initially thought the house had been used as a kinky sex den when she returned to the house after five days on August 16.

However Treivas left behind a business card for his company, Lucas Entertainment, which is based in New York.

After some investigating, Knapic found that her house had been used to shoot a porno, which has since become available online.

'The mistake he made was leaving a business card behind,' Knapic said.

'That’s when I realized that it wasn’t just kinky sex going on in there but actual film production.

'They left penis rings, lube, enema kits and sex toys.'

Knapic claims Treivas booked the house online under the name Anna.

She says he then arrived at the mansion claiming to be Anna's brother-in-law, saying she was on her way and he was sent to retrieve the keys.

Treivas admits to booking the name under his sister-in-law, who he says is named Anna.

He said Anna did not stay at the house but did visit while he and seven others were there.

Treivas denied anyone on the set was using syringes and said he has never used testosterone.

He said he left some 'medicine' in the fridge, and when he contacted Knapic asking for it to be returned, she said her cleaning staff had thrown it out.

Treivas said Knapic admitted to him in a text message that she had not been to the property since he had checked out.

Treivas also produced some online reviews from others that had rented the house and run into some issues with Knapic.

One Yelp review, written by a 'Ginalee G' from New Orleans, said Knapic kept part of their $1,000 deposit, claiming the spa needed to be cleaned, when 'only one person used it for about 20 minutes'.

'But to pay close to $6,000 for 5 days for rooms, no breakfast included and try and keep your deposit when everything was spotless is just wrong,' the reviewer wrote.

Other complaints: This review appeared on Yelp in July 2014, with the renter claiming Knapic wrongly charged her for damages and repairs

'Be careful': This Trip Advisor review said that Knapic kept a 'large portion' of a security deposit without justifying what damages they were for

Another review, on TripAdvisor, was titled 'Be careful', and warned that 'Kristina, the owner, retained our large security deposit for almost two months claiming that we had damaged several things during our stay'.

It continued: 'Eventually she returned some of my deposit, retaining a large portion for repair and replacement of items, which as it turned out were in such a broken-down condition that they were already on their last legs. We do not even know if these claimed damages were legitimate beacause the owner failed to provide any credible backup for her claim ... Many things throughout the property are in a similar state of disrepair and poor maintenance. BE CAREFUL!'

Airbnb released a statement about Knapic's complaint, saying they are investigating and that Treivas had been banned from using their services.

'Over 60 million total guests and hosts have had safe, positive experiences on Airbnb, and negative experiences are incredibly rare,' an Airbnb spokesman said in a statement.

'When they do happen, we work quickly to make things right.

'We have been in contact with this host and we are working to support them under our $1 Million Host Guarantee.

'We have zero tolerance for this type of behavior in our community, and we have permanently banned these guests from Airbnb.'

Knapic described the state of the 1929 Spanish revival property as looking 'very shocking' after returning after five days.

She said there were bodily fluids on the floors, in the beds, in the nightstand drawers and in the trash,' according to her lawsuit.

It also states that 'various sexual devices were found in the beds and in the trash...The hot tub water was brownish in color,' The Smoking Gun reported.

Knapic said that she was able to identify who had stayed in the house when she found a business card for Lucas Entertainment.

The lawsuit demands that Lucas must not sell or distribute any footage he took from the house

The cost of the five-day stay was nearly $5,000, Knapic said.

But she has put in a claim of $30,000 to Airbnb saying the renter had asked to book the property for a 'summer vacation,' according to the lawsuit, according to The New York Daily News.

The lawsuit demands that Lucas must not sell or distribute any footage from the house Knapic refurbished after buying it 11 years ago, she told The New York Daily News.

Adding: 'Plaintiff has not, and does not, rent the property for the purposes of filming adult pornographic movies,' the lawsuit said.

The lawsuit also states: 'Such an image is not one plaintiff wants associated with her pristine home'

'Such an image is not one plaintiff wants associated with her pristine home.'
