I miss living in London.
Told this before. I was on a fairly crowded Northern line train - the old ones with back to back seats and I felt a lick on the back of my neck.
I turned round to give a mouthful to who ever it was only to find myself looking in to the adoring brown eyes of a dog and a very embarrassed owner.
One from my childhood in a northern town.
I had some after school activities so I didn't always get the early bus home but this day I did.
The bus pulled in at a stop by a block of flats, everyone moved over to the side nearest the flats to get a look at the man standing naked in the window playing with himself.
Then someone noticed Sr Mary Dominic was on the bus, and everyone moved back and pretended they hadn't seen anything / moved/ cheered.
Did I mention this was an RC girls' school?
There was an 'emergency' assembly the following day for anyone who caught that particular bus home. It had been going on for a few weeks. Sister Mary Joseph was not happy that it had not been reported.
I guess these days everyone would whip out their phones to video The Sex On the Circle Line. That might or might no stop them.
'Public' is quite a popular genre of porn. I would be tempted to get out my phone and ask which website they wanted it posting on.
