This was years ago, when I was 21 and my girlfriend, Julie, was 19. We used to go for a drink in the local pub, and sometimes when Julie got a bit tipsy, she'd 'accidentally' let her short skirt slide up so any bloke passing would get an eyeful of her legs and thighs. Or she'd let her legs casually slide apart, so from the right angle they'd almost be able to see her knickers.

It was nothing too full on, more just innocent fun - Julie wasn't a slut or anything. But it really turned her on when she was in the mood. It always ended with us having steaming sex. But we never did anything really outrageous, and never engaged with any of the other punters who'd got a quick flash from Julie.

Then one night there was this smart looking bloke sat by himself a bit away from us. By 'smart looking' I mean his obviously expensive clothes looked a bit out of place in this back street boozer. Plus he was bloody good looking - a cut above the rest of us LOL.

Anyway, it looked like he'd been waiting for someone and had been stood up. Eventually, he got up to leave and headed to the loo on the way out. I nudged Julie and said, “Go on, give the guy a flash when he comes past.”

She giggled, then slid down in her seat - we were sat side by side on a bench seat, and she was on the outside - and angled her legs so he’d be able to see lots of thigh when he came out of the loo. “Spread your legs a bit,” I whispered. Julie giggled again then did as she was told.

“Here he comes,” I said and Julie started chatting to me, as if she didn’t realise she was on view.

The bloke came towards us, eyes glued to Julie’s thighs - and then he looked up suddenly and caught me watching him. He grinned, clearly aware that I knew what Julie was up to. Then he walked past.

“He got a real eyeful,” I whispered to Julie. “And he loved it!”

Julie straightened up with a satisfied smirk on her face. Knowing how I got turned on by her showing herself to other men, she slipped a hand under the table onto my lap and began to rub my already rock hard cock.

 “Looks like someone else loved it …” she began - and then suddenly the bloke was back. Julie pulled her hand away guiltily, making it even more obvious what she’d been doing.

“Hey, you don’t mind if I join you, do you?” the bloke said, placing a pint on our table and already pulling out the chair on the opposite side of the table. 

“Um, yeah, sure,” I mumbled. Julie said nothing, just looking down at the table in embarrassment.

“Thanks,” the bloke said. “I could really do with some company. I’ve been stood up. I great guy like me! I’m now a Norman No Mates!”

He said it in such a self-mocking way, with a comic expression on his face, that both me and Julie laughed. And then he was away, introducing himself as Mark and explaining he was back “in the old neighbourhood” on business. Even though he was at least 10 years older than us - early 30s, which is ancient when you're just out of your teens! - we were soon chatting like we’d been friends for years. He was just that kind of person - someone you couldn't help but like. 

And Julie was soon eating out of his hand. He had what I think is now called “rizz” - the sort of charm and charisma that women love. Nothing over the top, just little compliments, smiles, funny stories and stuff. Not that I really noticed at the time, but he was pretty much seducing Julie! 

So when he offered to buy us another round, pushing a fiver into my hand (shows how long ago this was!), I was happy to leave them together and go to the bar.

When I got back with the drinks, though, Julie had shuffled across and he’d moved to sit next to her. I sat down on the chair he'd been in and he just started asking about how the local footy team was doing. So me and him had a blokey football conversation, while Julie just sat quietly listening. Or that’s what I thought she was doing.

Suddenly she interrupted. “There,” she said, passing him something that I couldn't see.

Mark's eyes widened as he looked down at what she'd given him. Then he grinned at her.  “Oh good for you, you little minx!” 

Julie's face was flushed but she looked pleased with herself. She didn't look at me though.

Mark turned back to me. “I had a little bet with your gorgeous girlfriend” - again he smiled at Julie and she reddened even more - “that she wouldn't be brave enough to, um …”

He tapped my leg under the table and passed me what Julie had given him. It was some material - and when I straightened it out, I saw it was a pair of plain blue knickers. For a minute I was confused, then I realised. 

Julie must have slipped her knickers off under the table. I looked at her, not knowing what to say (though my cock was rock hard again in an instant). She'd gone bright red but still wouldn't look at me.

Then Mark broke the awkward silence. “I didn't think you'd really do it - or do it without anyone noticing. You really are a naughty girl!” he said to Julie, obviously patting her on the knee under the table. “You guys are great,” he went on, turning back to me, “I'm so glad I bumped into you!”

Then he was off again, chatting away as if it was the most normal thing in the world to get a stranger’s girlfriend to strip of her knickers in a pub! 

Only later did I realise that his hand didn't come up from under the table. Julie didn't really take much part in the conversation, but she did squirm about a bit, biting her lip - now I know it was because that horny bastard obviously had his hand up her skirt. And she let him!

Before I really knew it, we'd had another round, and then we were outside clambering into a taxi. Mark had insisted we come back to his hotel “for a nightcap”.

It was a traditional black cab, and Mark and Julie had ended up on the big back seat, and I was facing them on one of those fold-down chairs.

Mark gave the hotel address to the driver - then just pulled Juile towards him and began to snog her. I just sat there in shock. Then he broke the kiss, and looked over at me. “Hope you don’t mind, mate, but you’ve got one hell of a girlfriend here.”

He moved Julie round a bit, so that she was half-lying across the back seat. Her eyes were closed and she was breathing quite heavily, her breasts visibly rising and falling beneath her white blouse. Her face and neck were flushed - just like they were whenever we had sex.

They’d started snogging again, only this time Mark’s began to fondle Julie’s tit’s, first over her blouse, then pushing his hand up under her clothes.

He broke off kissing again to look across at me. “This is what most most attracted me to her,” he said, pushing Julie’s legs apart and pulling up her short skirt. Her nicely trimmed bush of tightly curled black pubes (this was in the days before shaving was all the rage) now fully exposed. 

I could also see the glorious flushed pink of her pussy lips - and then Mark’s hand came down. First he rubbed at her engorged clit, peeking out from her nest of hair, making Julie sigh and squirm - then he slipped one and then two fingers into her slit. Julie moaned.

“Oh my God, mate, she’s so wet!” he said.

I looked at him and then down at Julie’s spread thighs. They began to snog again as his fingers moved in and out, rubbing against her clit.

I was still in semi-drunken shock. How had the night ended up with a stranger with two fingers knuckle deep in my girlfriend’s juicy pussy?
