Ha! Very lol-worthy mate
The rules of the Tube:

1) Never talk to strangers
2) NEVER TALK TO STRANGERS

Unless they're beggars, in which case it's perfectly acceptable to advise them where to get off*

Which brings me to an anecdote where I was sat on a Northern Line train myself. I was desperately trying to avoid a Romanian beggar with a baby wrapped up in her arms, her leathery face wailing and crying as she extended a pathetic, torn paper cup jingling loose change in the face of each passenger in turn.

As she made her way down the carriage, we all did our best to pretend she wasn't. Then her ears pricked up, a sound had caught her attention; it was the sound of hands manipulating jingly-jangly coins at the end of the carriage!

She ignored the rest of the seated passengers and made her way surprisingly quickly to the man shuffling around in his trouser pockets. As she arrived, he removed his hand to reveal a police warrant card, then he said quite loudly "British Transport Police, off the train now madam".

Being British, we all silently cricket-applauded him in our heads. A few of us even raised a smile.

That's fucking great, that is!
The Tube would be a very good, but very British and London-centric QOTW.

I remember one time overhearing a couple down at Warren Street late at night.

Her: "I desperately wanna give you head when we get on the tube."

Him: "Yeah, lets find a carriage to ourselves!"

After a ponderous pause she said: "We'd better take the Northern Line in that case - the Victoria Line's too juddery... Might bite your cock off..."

Whenever I'm on the Vic Line now I always think of that random conversation.

(And get a bit hard).

Arf!
I recall an 'inappropriate head' situation while working in HMV... a couple had found a dark corner of the world music section and were getting down to it when I stumbled upon them.

Ever one to provide good customer service I uttered the words:

"Can I help you with anything?"

"You could cup the balls...

Otherwise, no thanks :)

Me and my ex
(the one from last week) used to experiment with risky public sex quite a bit. On one impossibly-crowded central line train on a sweltering summer's day, we ended up jammed in the middle of the carriage pondering a fairly long and unpleasant journey back to Mile End after a shopping trip in the West End.

The person sat directly behind me got up to leave, so I grabbed the seat immediately and pulled my g/f onto my lap.

Within moments, I had a raging hard-on, of which she was obviously aware, as she expertly managed to undo my velcro flies (I was wearing surfing board-shorts) and start prodding my cock into her thong underneath her summer dress, slowly working the stringy bit out of the way.

Sadly, it wasn't to be. I managed to get about half the tip in before the carriage started thinning out at Liverpool Street, and my tube glumly exited her tunnel and was returned to its sweaty lair.

On the Bakerloo Line
going up to Ikea one day (ohh, the joys of being coupled). The Mrs. was feeling randier than a priest in a schoolyard and there we had a carriage to ourselves.

She stood up, pulled up her short summer dress, pulled down her panties and wiggled her fine arse in my face.

I use the Bakerloo line lots for work and knew I had about two minutes before the next stop, more than enough time to get inside her and squirt my sticky load; we'd just have to find something else to do for the other minute-and-a-half.

So, I spring to action, whap out the little man, and slide him up the Mrs' lovely tight and incredibly moist love tunnel.

She's grabbing hold of the railings to steady herself while I grunt and pant like a fucking asthmatic running the marathon.

Suddenly the PA crackles and we hear the driver say:

"To the couple in carriage four - I'd just like you to know that that little round thing in the ceiling near the central doors is the CCTV camera."

And then the PA cuts off dead.

The Mrs. jumped so much she nearly snapped my cock off.

Brilliant :)
I knew you'd have a similar tale with which to raise me

I've put 'Public Sex' in the QOTW suggestions list
Can't promise anything, though - it's a toss-up (oh-ho!) between that and "My Hilarious Blu-Tac stories"
( Scaryduck LIKES EGG, Wed 22 Apr 2009, 11:18, closed)

How about Hillarious public sex stories involving blu-tac?
I'm sure everyones got shitloads of those.

A mate of mine once had sex with her boyfriend in a CCTV-controlled office car park.
On a the summer evening. In the open. She weighs 23 stone and he was a policeman, and they were both married to other people.

Every week I watch 'Feck Me, It's CCTV!' but I haven't spotted them yet.
