THIS is the moment a s.3.x-mad prison officer who appeared in an X-rated tape with a lag joined her husband in a 15-person orgy on a racy swingers show.

Linda De Sousa Abreu, 29, had s.3.x with a lag at HMP Wandsworth in a s.3.x tape which was circulated widely.

Footage has now emerged of Linda on Channel 4 swingers show Open House: The Great s.3.x Experiment.

She appeared on the show last year alongside her MMA fighter hubby.

Introducing herself, Linda said: “Monogamy is a social construct that I think needs to be dismantled.

“Opening up our relationship has allowed us to form a deeper connection with each other.”

Linda told how she and her husband had been “open” for three of their nine years together.

In the following episode, Linda is seen twerking in front of a woman’s face before kissing a man and a woman at the same time.

She then follows 14 other people including her husband upstairs for a full-frontal orgy.

In another scene, Linda and her husband briefly meet with a couple and float the idea of a potential foursome.

The woman from the couple describes Brazilian-born Linda as a “fire, crazy s.3.xy girl”.

But when the woman says she is from south London, Linda jokes “That’s not too far from the nice area”.

She then claims to live in Chelsea before the couples go their separate ways.

Prison officer Linda was seen performing a lewd act and having s.3.x with a burly lag as her radio crackled with messages.

X-rated footage of the acts – filmed recently by another con – was circulated among lags using illegally-held phones.

During the footage, the inmate filming the tryst joked: “This is how we live at Wandsworth.”

Linda is also believed to have an explicit OnlyFans account.

She is understood to have quit her job as a prison officer after the footage emerged.

Her sister told the Mail: “She’s a swinger. She was on a Channel Four programme called Open House.

“I never saw it. It’s not the sort of thing I’d watch with my little sister in.”

The sister added: “I only found out that she worked for the prison service in January.

“That’s when I spoke to her and said do not mix your lifestyle with work. Don’t be stupid, don’t do stupid things.”

A woman has now been arrested as part of a probe into a s.3.x tape allegedly filmed inside HMP Wandsworth.

The suspect is being held on suspicion of misconduct on public office after her arrest yesterday.

It comes after the shocking clip showed Linda on her knees performing a s.3.x act on a lag with his grey shorts pulled down.

A second con – seen on camera and apparently smoking a cigarette – says: “This is a movie innit – gangsters online.”

The jail guard then takes her black jail-issue trousers down and starts having s.3.x with the lag against the cell-door.

As she does so, her jail radio crackles with messages which mention “all stations” and “activity patrols”.

She continues romping with the well-built lag, who has white Nike socks and trainers still on.

The second con reassures his pal no-one will come in and says: “I’m on the door.”

He then puts his mouth over Linda’s mouth to muffle her moans.

As they continue to have s.3.x, the prison officer’s white prison blouse is visible.

Her belt – usually containing handcuffs, baton and pepper spray – bounces up and down on her waist.

The second con, with a beard, holds the cigarette in view of his camera and says: “This is how we live at Wandsworth, bruv. Yeah.”

As a male voice comes across on the discarded radio, he responds to it saying: “Shut the f**k up.”

Addressing his pal, he then says: “You know you are a gangster, innit.”

As the romping pair stand up, he adds: “No-one’s coming through by door, bro.

“I will fight them. No ones coming – do your ting bro.”

The camera then pans past a table full of food, cleaning products, deodorants and a bottle of baby oil as the second con says: “You know we are family.”

Yesterday the lag’s girlfriend and a young child turned up at the South West London jail in a blind fury, sources say.

A source said: “There is a shocking lack of discipline at Wandsworth and loads of the staff are young and really inexperienced.”
