A judge will have to view a 40-minute video of a care home employee mounting a sex attack on a woman suffering from a mental illness.
The film was secretly shot in the Droitwich home for adults with autism.
It shows Nigel Hoskins putting his hand down the trousers of the victim, who is in her 20s, and making her do the same to him, Worcester Crown Court was told.
It also reveals him kissing the woman and straddling her, said Susan Cliff, prosecuting.
Hoskins, aged 45, of Whites Road, St John's, Worcester, pleaded guilty to sexual activity with a woman with a mental disorder while acting as her carer.
Judge John Cavell adjourned the case for a pre-sentence report and granted Hoskins bail.
He will be dealt with in the week beginning August 17.
Mrs Cliff said Hoskins’ mobile phone was also seized by police. Six indecent images were found on it.
She said the judge who sentences Hoskins needed to view the video first.
Hoskins was ordered to sign the sex offenders' register before leaving court.
