Said her husband would collect it - then offered a him a 'one-off session'

A Gumtree seller was left shocked when a woman hoping to buy his treadmill sent her a picture of her backside and asked if he was interested in some 'extra-marital fun'.

Lee Kucia, 31, was sent a picture of the woman's bottom wearing only a pair of tights after she had repeatedly referred to the fact she had a husband who would collect the item.

The retail sales assistant from Rotherham, South Yorkshire, presumed it must have been an error when she quickly apologised for sending the image.

However, the woman then proceeded to try to get a discount on the Gumtree-listed electric treadmill by offering some 'extra marital fun'.

When Mr Kucia declined, saying he was seeing someone, the woman was still not put off and asked: 'Not even for a good one off session?'

In a bid to stop any more messages, Mr Kucia then pretended he was gay as he felt she would not take no for an answer.

Mr Kucia, who is currently single, said: 'The conversation started perfectly normally with her getting in touch asking if the treadmill was still for sale and trying to arrange collection.

'I was really pleased as I'd been hoping to get rid of it for a while as I was now using the ones at the gym so didn't really need it.

'She kept sending more and more weird things, but whenever I thought it was getting a bit strange she would then apologise or follow it up with something normal.

'When she sent me a picture of her bum in the tights I didn't know what to think, but she then apologised about it so I presumed it must have been a mistake.

'Clearly I was wrong as in the end she tried to get me to knock down the price by offering me sex. I was quite shocked to be honest. I just thought "wow", I should probably avoid her!

'She was not put off at all by my lie that I was seeing someone so I implied I was gay in the end - it was the only way I could be sure she got the picture that I wasn't interested.

'I definitely won't be selling it to her as I was left very worried by her messages about what might happen when they come round.

'I'm unsure how her husband could react to it all - he could be angry or happy about it and I'm not sure which is scarier.'

The conversation started normally enough on Sunday morning when she texted him asking: 'Hi, regarding your advert on Gumtree is the treadmill still for sale?'.

Mr Kucia replied: 'Hi, yes it is. Which one is it you are interested in as I have two. Lee.'

After a short discussion, the woman said: 'I need to shave a few pounds off my bum, legs and thighs. X.'

Mr Kucia ignored the message and only responded once she sent a regular inquiry asking for his address.

On Monday, he sent her a message on WhatsApp asking if she was collecting the treadmill that day.

Instead of replying via WhatsApp, the woman texted him: 'Hi. Thanks hun xxx your timing is impeccable just getting dressed lol*. Xx'

She followed this up with a smiley face emoticon and a pair of alarmed eyes.

The messages start quite innocently, with simple inquiries about the treadmill (pictured, left), and her saying that she was away at the weekend so would send her husband to pick it up

The inquiries start to get slightly stranger, with mention of her husband and ex-boyfriends, and a message about the fact she is 'just getting dressed (right)

She mentions her plans for the weekend (left) but then sends the picture of her bottom via WhatsApp separately, and offers 'ex marital fun' (right)

It was only eight minutes after that Mr Kucia then received a WhatsApp message with a picture of what appeared to be her bottom wearing only tights followed by the message 'tights on lol'.

When he failed to respond to this she then then texted him apologising for the picture and tried to arrange a collection time.

Mr Kucia said: 'All my friends keep asking if I have sold her the treadmill yet. They all said the interaction reads like the start of a really bad porno. They thought it was hilarious.

'Some have been encouraging me to meet her as they say she could turn out to be beautiful. But I am not tempted at all - I have had enough weird women in my life!'
