"Come in Sandra, I'll tell you what the matter is."

Sandra is one of those people who's glass in life is always at least half full - a real optimist. She's in her mid-forties, a redhead and is a slightly pudgy five feet six, and divorced with no new man in her life. Compare that to me. I'm a mid-forties blonde divorcee who stands at just under five feet nine and who still looks trim. It seems life is unfair - her outlook is far more positive than mine.

So, I took Sandra into the lounge and we sat down and then I told her my woes.

"That's not so bad. I know someone who can help you, if you want to be helped but it's not something that would appeal to everyone." She said, smiling.

"Go on,, what are you talking about?"

"I'm talking about making money from your body."

"Prostitution. I think I'm a bit too old for that."

"No, not prostitution, but an adult opportunity, yes."

"What's the difference."

"I'll explain. I know this guy who operates an online site and he's always looking out for models of a certain disposition. Not necessarily good lookers, or young, but ones that have the right attitude. And, from what he's told me, he makes good money at what he does, and he pays the models pretty well."

"Such as?"

"Such as last time I volunteered for one of his challenges, I made a hundred quid for just over thirty minutes of what you might call work."

"What did you have to do, blow him off?"

"If you listen I'll tell you what I did."

"Okay."

And Sandra did.

"And that is what he calls the thirty minute challenge." Sandra concluded and then admitted, "I've done that a handful of times now, not because I need the money but because it's something I actually get a kick out of - and finding something that thrills me at my age and being single, is not usually that easy to do."

"Thirty minute challenge, and you say he pays a hundred."

"He pays me that but there is one condition. To get the money you have to complete the challenge first."

"And is there a catch?" I asked, not sure if it was as simple as it all sounded when Sandra had explained it.

"No, it's just as I described it to you. He does longer challenges involving other equipment, and they pay more, but you have to complete the thirty minute one before you can move on to something more involved."

"Makes sense. So how do I get in touch with him, what was his name?"

"Marcus. I have his number so I can call him if you want me to." Sandra was already opening her handbag, looking for her mobile phone.

"Okay, yes please." I had no real choice and no way of making a hundred quickly other than the idea Sandra had mentioned to me. I just hoped paying in a hundred would appease my bank manager. Okay I was still using a credit card for food and so on but paying off that would have to wait, for now.

"Hi Marcus, it's Sandra. I have a friend here, called Chloe. She's a bit short on cash right now, but she has a good looking body and she was interested in your thirty minute challenge. I don't suppose you could have a chat with her and see if you think she's suitable?"

There was a pause and I could just about hear a male voice on the other end of the phone.

"Okay, thanks Marcus. I'll give her your address and the instructions. Usual preparations I presume."

Another, shorter, pause.

"Okay, I've got that. And I'll call you in a few days. I'm interested in the next level up, if you think I'd cope with it."

Another short pause.

"That's great. I'll talk to you soon. Bye love."

The phone call was ended.

"Right, you need a pen and paper," said Sandra, all business-like.

I fetched the paper and pen and wrote down everything Sandra told me, the address, my appointment for that evening at seven and what I had to wear and do before I got there.

"And, to be honest, if you haven't cum in a while, I suggest you get the worst of it out of your system. What he does is bloody intense, great stuff, but if you haven't fucked or cum in a while, you'll get to the peak too quickly and you'll find the second stage too much of an endurance test.
