Eddezider Herak, 36, her alleged pimp, is said to have raped her at the two-storey house in Midland Road, Gloucester (general view pictured).
A young woman was trafficked into the UK to work as a prostitute and raped by her pimp at a brothel run from the former home of serial killers Fred and Rose West, a court heard.
The 22 year-old Czech national was one of many women lured to Britain to be sold for sex at brothels in London and the west country.
Eddezider Herak, 36, her alleged pimp, is said to have raped her at the two-storey house in Midland Road, Gloucester before his mother Ludmila Nistorova, 53, sold her off to a man for £1,000.
Rose West had murdered Fred's stepdaughter Charmaine in 1971, burying her under the kitchen floor at the address.
Her skeleton was not dug up until 23 years later after the Wests were arrested over 11 more murders at their new home nearby - 25 Cromwell Street.
Prosecutor Emma Deacon told jurors at Isleworth Crown Court how the Czech woman was raped by Herak at the brothel.
'While she was trying to sleep Herak came to her and touched her and had sex with her,' she said.
'Three to four days later she was raped again by Herak. She told him she did not want to have sex and he carried on regardless.
'The mother and son controlled her prostitution and instructed her on services she should provide.
'The customers paid Herak and she did not collect any money herself and just took food and cigarettes.
'She was working as a prostitute in Gloucester and most of her clients were of Asian origin.'
Jurors heard the victim was then raped repeatedly by Magezi Clague, 42, who is also accused of sex attacks on a 19-year-old Czech girl.
It is claimed traffickers also forced the women into sham marriages with foreign nationals.
The prosecutor told jurors how vital information on a brothel in Tooting, southwest London, was handed in anonymously to a local police station, prompting a seven month investigation.
'An envelope was received at Tooting police station, and inside it detailed all of the workings at that premises,' she said.
'Information regarding the allegations of prostitution, sham marriages, and credit and bank card fraud were inside.
'It detailed the cars they drove, and that they would pick up young girls who had gone astray in the Czech Republic and brought them here to work.
'When the arrived they would be prostituted in Tooting and Croydon to mainly the Asain community.'
The prosecution claim the information detailed how mother and son Iveta Viragova, 44 and Vojtech Virag, 26, helped traffic the girls into Britain to work at the brothel on Mitcham Road, Tooting.
The gang later set up sham marriages between the girls and their clients, to help them stay in the country.
Two other men, Teodor Hunka, 41, and Zdeno Sarissky, 29, are believed to have helped recruit the women from the Czech Republic, promising them over £2,000 to travel to the UK and participate in a sham marriage, before they were forced into prostitution.
Hunka, Sarissky, and Herak, all of no fixed address, Nistorova, of Gloucester, Viragova, and Virag, both of Tooting deny conspiring to traffic young women into the UK and within the UK for sexual exploitation and conspiring to control prostitution.
Viragova denies perverting the course of justice and Virag has pleaded not guilty to conspiring to assist unlawful immigration.
Co-defendants Hunka, Sarissky, Herak, Nistorova, and Viragova, have admitted sham marriage charges.
Herak denies two counts of rape.
Clague, of Paddington denies four counts of raping the same woman plus two counts of raping a 19 year-old Czech girl.
He also denies trafficking young females within the UK for sexual exploitation and controlling prostitution for gain.
The trial continues.
