Lydia, home for the summer before university, sprawled languidly across a recliner in her parents' Surrey garden. A paperback copy of Daisy Buchanan's "Insatiable" lay face down on the grass beside her.
Eighteen years old, coltishly pretty with legs a mile long, she wore high cut navy bikini bottoms, and nothing else, the top long since discarded to encourage the most even possible tan. Her pert breasts stood high and proud despite her prone position.
She had gathered her chestnut hair into a messy bun, and her oversized sunglasses covered much of her tanned face.
Her boyfriend Josh lay beside her, wearing a pair of swim shorts. Josh was broad shouldered and tall, with a mop of raffish blonde hair and a body that spoke of early morning rugby training and no little vanity. His chest sported an impressive display of chest hair with a long dark trail pointing the way down to his waist.
At this particular moment in time, Lydia was idly playing with said trail.
"This is nice. I'd like Tuscany more, but this is nice."
"It's particularly nice that your Dad's away."
"Oh don't be mean, Josh. Daddy doesn't hate you as much as you think!"
"I mean, he definitely does. There was that one time he said I had the height for the England second row. But that's as close as he's ever come to being nice to me."
"That's just him. Anyway, Mum likes you. Or she fancies you, which comes to the same thing!"
"Ha ha ha. So funny, you are". Josh leant over and kissed Lydia on the top of her head.
"So sunburnt you are- look how red you're getting". Lydia gently poked Josh's flat stomach just above the line of his shorts.
In return Josh ran a finger across Lydia's bare little breast, enjoying the slightly oily feeling of well-applied suncream. "Some of us didn't spent as much time rubbing lotion on ourself as others."
"I offered to oil you up, but you were very macho about it all."
Josh ran his finger back around Lydia's breast. She giggled. "Are you up to no good?"
"Me? Never."
Lydia looked down, and saw the unmistakable sight of Josh's shorts beginning to form a tent at the front. "Again? I thought I'd worn you out this morning!".
"It's an entirely natural reaction to seeing a pretty girl's tits, as you well know."
Lydia giggled. "What's the entirely natural reaction to a pretty girl giving you a handjob?"
And she slipped her hand down his stomach, under the waistband of his shorts, and through the wiry thatch of hair above his manhood.
"I'm not sure this is the best place, babe."
The garden was sheltered on two sides by high hedges, with a less well-kept fence right at the far end leading to a shallow stream and public footpath. Josh and Lydia's bower towards the bottom of the garden was reasonably sheltered from public view, but overlooked by the kitchen window of the sprawling old farmhouse that Lydia called home.
"Seems pretty good to me," replied Lydia, as her hand grasped Josh's thickening cock. "Now help me out here and get those shorts off".
Without any further protest, Josh lifted his bum enough to wriggle the shorts to his knees.
His freed cock sprang upright, guided by Lydia's slender fingers. She squeezed it firmly as he felt it swell further, the head already a furious purple colour.
Lydia lowered her head, kissed Josh's muscled stomach, then with slow but insistent motions began to masturbate his aching prick.

Lydia's mother, Caroline, looked out of the kitchen window, as she absently dried a coffee mug with a worn old tea towel.
Seeing her young daughter sunbathing with her beau took her back to her own summer days- flirting with Italian and French men as she travelled around Europe, giggling barefooted at summer parties, and artlessly sunbathing topless with just the right amount of faux-continental sophistication.
Caroline was nearly fifty, her ash blonde hair still expensively cut and coloured to best set off her fine-boned features. Regular sessions with a personal trainer kept her in reasonable trim, though she was on the verge of losing an ongoing dispute as to the health benefits of expensive chardonnay.
Nevertheless it was clear where pretty Lydia got her looks from- Caroline was every bit the trophy wife. Lydia was their only child - her husband Matthew had only wanted one- and his career in the City had meant that they had been able to spoil her rotten over the years.
Caroline watched Josh and Lydia talking, sprawled on the recliners. She couldn't hear what they were talking about, but Lydia was clearly amused as she insistently explained *something* to Josh.
Caroline pursed her lips disapprovingly as she saw Josh's hand on Lydia's breast. She frowned even more as her daughter's hand disappeared into Josh's shorts. Heavy petting was one thing, but this was practically *sex*, in the open air and in plain sight.
Caroline was no prude, and she was realistic enough about the fact that eighteen-year-old Lydia had been enthusiastically sexual active for some time. She took a liberal approach to hosting boyfriends, on the grounds that Lydia was an adult woman, capable of making her own choices (and frankly a couple of them had been terrible choices).
But that didn't mean they had to rub it in her face, metaphorically speaking.
Putting the tea towel down, she readied herself to march to the back door of the kitchen, and loudly open it to announce her presence. But as she glanced back out the window, something halted her progress.
Josh's shorts were down around his thick thighs, and his large cock was standing stiff and proud in the air, with Lydia's hand firmly wrapped around it. She was pumping it up and down with slow languid strokes. Josh's eyes were closed in pleasure, and his hands gripped the edge of his recliner.
For what seemed like an eternity Caroline stared out the window.
She felt a warm unmistakable ache between her legs, and before she even knew what she was doing Caroline pressed herself against the kitchen counter.
As she watched Lydia jerk Josh off faster she unconsciously mimicked her daughter's pace, her denim clad hips inscribing circles against the wood cupboard.
And with the energy and enthusiasm of a young man, it wasn't long before Josh reached his climax. As Lydia's hand slid up and down she saw him jerk thrust his hips upwards, before what looked like an endless stream of come shot out of his dick. The angle and the tension sprayed Josh's seed across his own chest, with a great deal also coating his eighteen-year-old girlfriend's hand and wrist.
Caroline, not caring by this point, unzipped her jeans, and tugged them down over her fleshy arse. She pressed a hand against her pussy through her soaked white knickers, and began to rub herself vigorously. Her left hand clutched at the kitchen counter for support.
Suddenly, there was a loud crash, as the cup she had just dried slipped off the draining rack and shattered on the slate kitchen floor.
Caroline jumped, startled.
She had a moment of clarity as she realised what she was doing- masturbating in the kitchen in broad daylight as her teenage daughter got hot and heavy in the garden.
