Sandra von Riekhoff, 40, is happily married to the father of three children - but, fifteen year ago, she enjoyed an illicit relationship with a married man.
Now, in a bid to rid herself of the guilt she feels for being The Other Woman, she has taken to eBay to sell the expensive lingerie he bought her.
"I feel rotten for betraying his wife and accepting these gifts"
She wrote: "Thank you for looking at this piece of smutty lingerie. I have only worn it while drunk. It looks ridiculous otherwise. Try standing with it on, flat foot in broad daylight.
"It appears desperate."
She continued with her tongue-in-cheek posting, poking fun at the man who purchased the designer undies for her.
She wrote: "It was sold for £400 to a 40-year-old man 15 years ago - who clearly suffered from a mid-life crisis.
"He bought it for the 25-year-old shopgirl on Sloane Street he was trying to coax to the Savoy with expensive gifts.
"I have shoved this […] in the attic hoping the guilty memories would fade. They don't. I feel rotten for betraying his wife and accepting these gifts, even if she was as rancid as he claimed.
"Fast forward 15 years… I'm 40 now and I have 3 kids. She was probably doing her best. What 40-year-old woman is still a wildly fun ride with her husband after multiple children?
"I haven't worn this thing since 2007, before I had the children, before my udders tumbled towards my lower ribs and before the abs were nicely coated in cellulite and sagging skin. It's over.
"I tried Pilates at £50 a session with a bully instructor. I've tried the roll on 'instant results' stomach spreads you have to import from Spain.
"Jogging gives you 'jogger's face', that sunken hollow look that may mean you've got a fit body, but hell your face looks like the thing Jack Nicholson groped in room 237.
"This lacy French piece of tat is a reminder that 118lbs will possibly be mine once more just before the mortician decides what shade of beige cake to coat my face in for the 'last view'.
"To quote Shakespeare, 'every dog has its day', mine has past.
"Perhaps you've still got a few days left..."
She finished: "I suggest heels here, dim lights and a bottle of bourbon. I'm not too bothered about what this thing sells for, but if it does fetch anything at all I will use it towards buying a swim costume that cleverly hides the python wrapped around my waist.
"I'm simply relishing the idea of shoving this purple mistake in an envelope and hoping that with it, I can forget how hot I was once and just be happy that I'm still too young for Tena pants.
"Bidding starts at 99p. I will offer free shipping to anyone buying it from at least 10,000 miles away."
Wowzer.
The basque has sold for £17, so it wasn't a big money-maker - but maybe it did help to alleviate Sandra's guilt.
