A 26-year-old woman charged with murdering autistic teenager Aaron Pajich cut and choked her former lesbian lover as part of sado-masochistic sex play, a Perth court has heard.
Jemma Victoria Lilley and her housemate Trudi Clare Lenon, 43, allegedly killed the 18-year-old at their Orelia house then buried him in their backyard, covering the shallow grave with concrete and tiles in June last year.
Kim Michelle Taylor told their WA Supreme Court trial on Thursday that she had known Lilley very well for many years but stopped having anything to do with her about one month earlier.

They had previously exchanged many explicit messages about sado-masochism, with Ms Taylor once allowing Lilley to cut her lightly with a decorative knife and to choke in their sex acts, she said.
Ms Taylor also confirmed Lilley had been married to a now-deceased man named Gordon, who she referred to as ‘Gacy’ after the notorious American serial killer and rapist John Wayne Gacy.
‘It was just a nickname,’ Ms Taylor said.

She said the texts also heavily featured comments on the Dexter TV show, which is about a fictional serial killer.
The court also heard testimony from Lenon’s 22-year-old son Jacob, who said his mother was interested in horror films.
He was asked if she liked horses, given a riding crop was found in her bedroom, but he said no.

It emerged on the first day of the trial, which is now into its third week, that Lenon was for many years a submissive participant in the bondage, discipline and sado-masochism scene, and the ‘Corvina’ character she assumed had been awakened by Lilley.
Lenon told detectives the pair didn’t have a sexual relationship.
A text message from her to Lilley that was read out in a video-recorded police interview played on Wednesday read: ‘I am fortunate to have met my true dominant counterpart because without you, I would continue to feel shame.

‘… even writing this is highly erotic. You allow me to explore Corvina and I actually really like her.
‘So for all of this I say thank you.’
Lenon has admitted being an accessory to murder, which prosecutors have rejected, while Lilley denies involvement.
