At first I thought he must be selling something. He looked clean-cut and respectable, with a smart bomber jacket over his crisp white shirt and wearing a pair of black trousers and trendy geek-chic specs.
He stopped me as I was walking out of the HMV shop in Birmingham city centre, opening with a refreshingly polite 'excuse me sir' and throwing me his best attempt at a cute-boy smile when I gave him my attention.
As he babbled on it took me a minute or so to figure out what he actually wanted. Having expected him to ask me questions about my energy provider or some such, I think I was trying to somehow connect the words he was saying to British Gas or N-Power or something like that.
But he just kept going on about forgetting his ID and telling me some convoluted story of how far away he lived and how many buses he'd have to catch to fetch it.
"Sorry, but what is it you actually want from me?" I queried at length.
"I just need you to buy me a game," he said with shrug, like it was the most normal thing to ask of a total stranger you'd just met in the street.
Seeing me make to turn away from him, he quickly added, "I mean, I'll give you the money -- I'm not asking you to pay for it for me -- I just want you to go over to the cash desk to do that side of things."
"Why can't you buy it?" I asked him distrustfully, suspecting that I was being set up for a scam.
"That's what I've been telling you -- I forgot my ID," he replied, a touch on the irritable side. "I am eighteen -- I swear to God -- but I left my student card in my room."
I looked him up and down. He could well be eighteen. He had a cute, boyish face under his thick-rimmed glasses but his chin betrayed a fine growth of stubble. His build was on the chubby side and could still be described as puppy fat, but he was at least as tall as my son, who was also eighteen.
"So why did you come in to the city without your ID if you knew you were going to buy the game?" I asked.
"I was working this morning," he replied, gesturing at his white shirt and black trousers and throwing me a look like I was stupid to assume he always came out dressed like this. "A guy I work with told me about the game and I wanted to buy it so I can play it on my day-off tomorrow."
Seeing that I was still sceptical but could well be close to taking the bait, he took out his wallet and showed me that he had a stash of ten pound notes inside which I assumed would cover the price of the game.
"Okay, I'll buy it for you," I said brightly which made him smile rather cutely at me. "But in return, I'd like you to do something for me."
"If I can," he shrugged. "Whatever you want..."
I smiled back at him. This was exactly the sort of response I'd been hoping for.
"Whatever I want, eh?"
He nodded and I asked him, maintaining my smile, "Even if what I'd like you to do is of a sexual nature?"
He laughed at that -- he actually thought I was joking -- but when I didn't laugh back and just kept smiling pleasantly, he blushed and muttered there was no way he was going to "take it up the butt from some old geezer".
"I don't want to do that to you," I chuckled back. "I don't suppose the game is worth that much to you! I just want to... well... I have a very specific fetish."
"A fetish?" he asked, looking like this was maybe getting too involved to be worth a Sunday spent playing a game.
"It's not a horrible fetish," I reassured him with a smile, glancing around to make sure that the shoppers walking past us weren't paying attention to us. "It certainly won't involve any discomfort or... er... unpleasantness for you."
"I'm not gay," he snapped.
I nodded back. "I don't remember suggesting I thought you were."
I suddenly wondered if he worked in Boots on Saturday mornings: I'd noticed that the lads who were shelf-stacking in there wore white shirts and black trousers as part of their standard dress code. He didn't have a name badge on but maybe he left that in his locker at the back of the store.
He looked intrigued but cautious about what it was I was asking of him.
"I'm gonna need you to be more specific," he said. "I mean, I could probably order the game on eBay for cheaper, so it's not like it's a big deal."
"I'm sure you could," I replied, "and it's not a big deal for me either. But if I'm doing you a favour, it would be entirely reasonable for you to do one back for me."
He nodded slowly. "Yeah... of course... give and take and all that. I just need to know what it is I'm letting myself in for..."
"Without wanting to offend you... if I buy you the game, I'd like to... well... I'd like to lick your bum in return."
I smiled at him pleasantly, trying to look as casual as I could given the intimate nature of what I'd just asked of him.
"Lick my bum?" he asked, looking surprised and confused. "You mean you want lick my backside... my actual arse?"
I couldn't see how the word bum could mean anything other than an actual arse, but I nodded and said, "Only if you're willing to let me, of course."
"What, like, actually lick it?" he went on. "With my trousers and pants pulled down?"
"That's right," I agreed. "You'd just have to stand there and let me. It wouldn't be too onerous and I probably wouldn't need too long."
"Are you some kind of creep or something?" he asked me with obvious disdain.
"Not really," I replied cheerfully. "Just a guy who's willing to buy computer games for young lads who've forgotten their ID cards, and who also happens to have a thing for licking the same young lads' bums."
"My actual bum, though?" he clarified, like there could be any other part of him I was getting it confused for. "I mean... you know... the thing I shit through?"
"That's the spot," I grinned. "Just below your back and right at the top of your legs."
"And I'd just have to stand there?" he asked again, with people around us getting on with their shopping oblivious to the sort of conversation they were walking right past.
"Look," I said, "there's a coffee shop opposite. I could buy you a drink and we could settle things in a rather more civilised way than standing out here in the mall."
He looked at it warily. "And then you'll buy me the game?"
"Of course," I agreed. "But only after you've completed your side of the... er... transaction."

"Okay, so let's get this straight," he said after taking a mouthful of the lattΓ© I'd bought him. "You want to lick my arse?"
I gestured for him to lower his voice after a couple of girls sitting off to my left swung their heads round to peer over at the two of us.
"That's what you want to do, though, isn't it?" he asked in a more discreet whisper. "You want me to pull my trousers and pants down so you can crouch down behind me and lick my bare bum?"
"Actually, initially I'd prefer it if you left your underwear pulled up," I told him.
