Probably pretty close to the original supposition. When I was 41 working in a town in the south west, I had popped out for lunch and saw a girl sat on a wall outside the bakery I was going into. Nothing that special, 19 years old, lovely face though and gave me an immediate twitch. Bought my lunch and leaned on the wall near her and as she was eating the same sandwich as i was it was an easy talking point to knock up a conversation. Clearly I wanted to fuck her, and it was not on the cards as, well, I was an old geezer and she was 19. She mentioned she was taking a year out prior to Uni, and wanted to go away with her friends for a holiday but no money. I said "I might be able to help you with that", got her FB contact, added her up, and forgot all about it. 2 days later she flat out propositioned me saying £250 for an afternoon. She then backed out. Then came back again. I knocked her down to £150. Said no. Then said yes. Few days later just after work I arrived at her parents house (on hols) and was taken up to her older brothers room in the attic (at uni). We fucked a few times and chatted a lot as well finally leaving at about 10pm. Was her first time selling it, and she didn't want to take them money afterwards, and i made her take it, giving her some more. We communicated for a few weeks afterwards and I repeated a couple of times but I started losing interest and it was clear she was pushing for a relationship on the last time saying the money made her feel dirty and she wanted more than money. I explained to her in detail what a sordid dirty bastard I am and we agreed to stop it there. Fucked once more of course, and then I left.
I wasn't worried about solicitation as although I had inferred it, she had in written made the suggestion. However I knew what I was doing outside the bakers. In one way its one of the things I'm most ashamed of, and in another that first meeting was one of the most erotic and tittivating experiences I have had. She never went to Uni in the end, but has an arty career, and has turned into a beautiful young woman whom to the best of my knowledge did not continue prostituting herself not appearing on the usual places or SB sites.
