A woman who shared a sexy selfie on her husband's Facebook wall has gone viral after the ensuing comments revealed that she had cheated on him - with her own cousin.

The story, which involves a woman named Ashleigh Dempster and her husband Tim McGowan, appears to have been posted online by a Facebook friend of the couple, who shared it with the statement: 'I woke up to one HELL of a read today.'

The post on Imgur includes a whopping 75 screenshots telling the whole story, which the poster then summarized, writing: 'Girl posts selfie on husband's wall. People talk about it. Her cheating on him with HER cousin gets out. She admits it.'

Big story: A woman named Ashleigh Dempster was revealed to have cheated on her husband Tim McGowan's wall with her cousin after sharing a sexy picture on Tim's wall

Calling out: The drama started after a Facebook friend of the couple took to the post to call Ashleigh a 'w****'

Big reveal: After Ashleigh asked why she was called the derogatory name, Jennifer accused her of cheating on her husband with her cousin

She adds: 'Hilarity, cringe, and dank memes ensue. Husband stands up for her. She leaves him to go stay with her cousin.'

The posts begin with Ashleigh's racy selfie, shot of her in just her underwear in a laundry room.

The image was apparently posted via her husband's Facebook page, with the caption reading: 'Hacked by your sexy wife love you.'

But right away, one of the couple's friends quickly took to the post's comment section to call Ashleigh a w****.

Ashleigh defended herself, saying: 'At least my s***'s covered', but then the friend, Jennifer Cady told her: 'That's not why I called you a w****.'

After Ashleigh challenged her to tell her why she had been called the offensive name, that's when Jennifer dropped the bomb.

Surprise! To the shock of readers, Ashleigh went ahead and admitted to the indiscretion

No shame: Even after friends suggested she keep the story private, Ashleigh insisted 'I'm not embarrassed'

Blown away: People swarmed the comments to express their horror over Ashleigh's admission

'Cus [sic] you cheated on your husband by f***ing your first cousin, then now you are posting naked pics on his wall.'

Then, to the surprise of anyone following the thread, Ashleigh subsequently confessed to the accusation.

'I did cheat on him and f***ed my cousin. Call me dysfunctional all you want. I ain't gonna lie about it.' she said.

What ensued were plenty of comments from people shocked by the revelation, as well as one helpful friend who offered a friendly recommendation, saying she should be keeping such a story private.

'It's fine, dad's side and all mom's side knows, don't really car,' said Ashleigh in response, claiming that the family found out after her ex-boyfriend hacked her Facebook account, but insisted that 'I'm not embarrassed.'

Coming to defense: Eventually, Tim wades into the conversation to defend his wife

Taking it further: He even went so far as to admit that he had asked her to post the photo and called her 'the most beautiful woman in the world'

A final twist: In a separate post shared after an unidentified period of time, a post by Tim suggests that he had been left by his wife for her cousin

Dozens of comments of disgust followed, in addition to plenty of memes poking fun at Ashleigh's confessed incest.

Eventually, after being mentioned by plenty of commenters, Tim eventually waded into the conversation.

'Am I just ok with what happened hell no…' he wrote. 'Am I gonna crucify my wife and tell her to get lost because she made a mistake, no.'

Tim said that Ashleigh came to him after sleeping with her cousin and that he ‘made the choice to try and save my marriage’.

‘Love is about forgiveness and I stand by my wife because I love her,’ he said, and even revealed that he did ask her to share the sexy selfie on his wall, call her ‘the most beautiful woman in the world.’

After a series of additional memes and posts from horrified friends condemning Ashleigh’s actions, the poster shared yet another post from Tim’s page, which had been shared an unidentified amount of time after the sexy selfie.
