*****
The five members of the Delaney family were in the final preparations for their annual holiday. Always to the same cabin in the same woods in the same god-damned remote frickin wilderness.
Paul Delaney, at 39 years of age, had been going there since his father bought it. He'd taken his own family there every year for, what was it, sixteen years now? He loved it and genuinely believed they all did too.
Suzanne Delaney was two years younger than her husband. She was physically attractive in every way despite having had her children young when she was aged 19 and 20. She enjoyed their holidays, her pleasure over the years had always come from the fact that they were together, without the usual hectic merry-go-round of work and schools and grocery shopping and sports practice.
Their children were as typical as any suburban teenagers. The twins Lizzie and Mike - only their grandmother called them 'Elizabeth' and 'Michael' now -- were nineteen. The 'baby' of the family, only eleven months younger than the twins, was Samantha. She wanted to be called by her full name, or at the very least as 'Sam', to make her sound more mature. Which is exactly why the twins insisted on calling her 'Sammie'.
DAY ONE.
Paul had tried twice now to fit everything into the tray of the twin-cab pickup -- one of those half-pickup half-car things with two rows of seats inside and a ute-style tray on the back. They were only going for eight days but there was little of anything in the cabin and Suzanne always packed an extra two of everything.
Finally getting it all in and secured, he pulled the tarpaulin over the load, snapped the ties in place and began his checklist. Satisfied, he started his usual joke.
"OK. Me, check. Wife, check. Twin one, twin two - check. And where's little Sammie?"
"Stop it dad, I'm not little anymore and it stopped being funny ten years ago."
Poor Samantha. She was the shortest of the siblings and was desperate to be treated as an equal and not as the baby. The twins looked their 19 years, poor Sammie had just turned 18 but her short- cropped hair, freckled nose and slight build made her look younger.
"And dad, call me Samantha, please?"
The twins chimed in unison: "Sa
-Man-
Tha!"
"OK poppet. In you get 'Samantha'. And you two cut it out. We've got a long drive."
Rolling her eyes at the 'poppet' nickname, she climbed into the rear bench seat between the twins and settled in. As Suzanne got into her own seat in front she chided her husband a little: "Paul, she's too grown up to be 'poppet' anymore."
"Not to me, and she never will be." He caught Samantha's eyes in his rear-view mirror. She shared a loving smile with her father.
Seat belts on, the pickup roared into life and they began the four or five-hour trip. They were dismayed to see the traffic on the freeway, having hoped they'd left late enough to miss the morning rush.
The day having begun badly, it quickly got worse. After only an hour, and just as they left the city-bound traffic for the open road north, Sam needed the toilet. Her mother wasn't impressed.
"Seriously Samantha? Didn't you go before we left?"
"I
did
go. Now I need to go again."
There was a roadside rest stop sign-posted at 18 kilometres away, so Paul planned to pull in there. Eighteen klicks at this speed - a little over ten minutes... And then the caravan. Then the council road patrol truck. Then the old man and his older wife at 50 kph with one lane closed for road works. After fifteen minutes they were still not there and Sammie had begun to get uncomfortable. She tried to make a joke of it: "Wish I was a boy and could just nip behind a tree!"
Suzanne took a lead. "Do you want daddy to pull over so you can?"
"No! I couldn't..."
"Of course you can. I've done it, Lizzie has done it. Paul, find a spot. Look ahead there - three caravans in a row and right at the bottom of the pass."
The Mackenzie Pass is legendary for its torturous twisting climbs on a narrow road through the Black Range, not the place to be stuck behind slow vehicles with no place to pass or pull over. The intended rest stop was on the other side, still a few klicks away.
A farmer's driveway had to suffice. Paul pulled up twenty metres off the road, where the drive was enclosed with a treeline at the farm's boundary. Sam wasn't keen.
"I don't think I can."
Lizzie came to the rescue. "C'mon Sammie. I'll go with you."
Thus reassured, they hopped out of the pickup and Lizzie found a place behind the car and having checked nobody could see them, she smiled at her younger sister and pulled down her panties to pee. Sam did the same.
They squatted without peeing for some moments: Lizzie didn't really need to go and Sam was still shy. Suzanne opened her door slightly to let some air into the car at the exact moment her son looked sideways, and with the angle changed on the side mirror he could now see both his sisters squatting to pee reflected in it. He abruptly looked away, then couldn't help looking back.
From his view Lizzie was facing directly towards him, panties around her ankles held up and out of the way in one hand with her pink smooth pussy and puckered arsehole clearly visible between her smooth thighs. Sammie was at a slight angle so he was looking at the side of her thigh. He instantly got erect. He and both his sisters had bathed together as kids, but now Lizzie had the body of a gorgeous young woman and Sammie's thigh and bum held the promise of more female delight.
