A paedophile couple who drugged and abused their young children, sometimes during swingers' sex sessions that were recorded, have been handed the longest jail sentences ever imposed in WA for child sex offences.

The 41-year-old mother of the children was given a sentence of 28 years, while her 47-year-old partner was given 26 years in prison.
The couple, who cannot be named to protect the identity of their victims, pleaded guilty to a string of offences, some of which cannot be reported at this time.
The District Court was told the couple, who were members of the swingers' scene, were in a de facto relationship, but the woman's two young children regarded the man as their father and called him "dad".
The woman was also a prostitute and worked from the family home.
She will have to serve 26 years and he must serve 24 years before they will be eligible for release on parole.
The couple's crimes came to light in 2018 when a member of the public found a memory card containing two recordings in a short-term rental property and handed it in to police.
The recordings, which were previously described by a judge as "depravity of the highest order", showed the couple and other adult men repeatedly sexually abusing the woman's daughter, who was then aged about eight.
