A cleaner has admitted raping a disabled woman at her home in Edinburgh.
William Melvin, 50, attacked his 36-year-old victim, who has had cerebral palsy since birth, last June.
At the High Court in Edinburgh advocate depute Alison Di Rollo said the women knew the difference between rape and consent and had resisted.
Melvin, from Edinburgh, was remanded in custody to be sentenced next month, following background reports.
Ms Di Rollo, prosecuting, said that Melvin and his wife had befriended the woman, regularly checking on her.
Melvin would also watch TV in her house, particularly football matches.
During the evening of 28 June he told her he was going to the bedroom because there was a larger television set there.
The woman followed him and sat on the bed.
"He told her to remove her top to which she replied 'No thank you'," said Ms Di Rollo.
He then attacked and raped her.
The court heard that the offence came to light some days later when the woman phoned her mother, asking her to tell Melvin's wife that she didn't want Melvin in her house because he had been "touching her".
When questioned by police, Melvin tried to deny having sex with the woman but changed his story when told about the results of a medical check.
He then said she had been a willing partner but finally admitted he raped her.
The court also heard that when a psychiatrist interviewed the woman she told him: "I saw Billy on the bus about a month ago and he made me feel very dirty. What he did was wrong.
"I said no and he did it anyway."
