The horizon away up ahead seemed to be on fire as the sun sank behind the scrubby trees. Behind, in my rear-vision mirrors, the dust was a glowing orange cloud. The heat from the setting sun, and the throaty purr from my Honda AG XR Farmbike muffler were soothing, but sleep inducing. I had to take special care to stay alert on the longish haul back to the homestead, all the more so because my twin sister Kylie was riding pillion.
"Kris!" She tickled my ribs and chanted the time-worn, sing-song query. "Are we there yet?"
I didn't really need to answer that question. She knew the road at least as well as I did.
"I'm okay. Wide awake."
Which was what she really wanted to know. What she probably didn't want to know was that the vibration of the seat under my balls, coupled with the feel of her arms around my waist and her slim-trim body up against mine had given me a powerful erection. I'd realised long ago that because of her very small tits she never bothered to wear a bra, and I happily imagined I felt her nipples hot and hard on my back.
Five minutes later we banked into the machinery shed and came to a halt. The silence after the day-long hum of the motor was very welcome. Kylie dismounted, removed her open-face helmet and sunglasses, then fluffed her sweat-damp brown hair.
She rubbed her cute little arse and rolled her shoulders. "Ooh...ah. I'm as stiff as a board."
I managed not to grin. "Yeah, me too."
"My bike getting a puncture was a damn nuisance."
"Didn't matter too much." I replied. "We still got everything done."
I kicked the stand down to keep the bike upright, and got off awkwardly, striving to keep my back turned so she wouldn't see my massive boner. That strategy didn't quite go as planned.
"Thank you for looking out for me today Kris." Kylie came bounding around in front of me. "When the flat tyre chucked me off I didn't hurt myself, but it scared me a lot."
"It scared me too. I'm glad it turned out okay. Dad'll pick up your bike when he goes out there, tomorrow probably."
She exuberantly threw her arms around my neck and gave me a sisterly hug, albeit a dusty one. I tried to be discreet, but my disgracefully uncooperative cock had other ideas. It ploughed right into her front.
She stepped back and looked down with a startled giggle. "Oh dear. That is absolutely disgusting."
I felt a blush burn my cheeks. "Sorry Kylie, that just happens sometimes."
Still looking at my shame, she raised an eyebrow. "Well I'm sure it would have had nothing to do with me being squished up against you on the bike."
Oh God, she knew. Hmm, was it merely a shrewd guess on her part, or had she been turned on too?
"There is the possibility you were the cause of it." I challenged.
She slapped my arm, turned and walked away, then grinned back over her shoulder and swayed her slim hips as she stepped through the side door of the big shed.
I've already told you that Kylie and I are twins. We are eighteen-year-olds. We live on Tangarra Station, an eight hour drive 'way out west' of Alice Springs, in the Northern Territory of Australia. It's very isolated. No one around, just our Mum and Dad and Kylie and me, Kris. Oh, and Mum's parents, our grandparents. A while back they retired and moved out of the big old homestead into a new little house on the opposite side of the home paddock. It's a comfort to them to be nearby, and it's a comfort to us too, to know there's always someone around, despite the isolation.
We twins are in school year twelve, doing our studies on the internet, and I hope to do well enough to start on a Livestock Management Degree via Open University next year. Kylie aims to do something in Veterinary Medicine. We are well ahead in our studies, so are able to take an occasional day off to help with chores.
We have satellite TV, and satellite phones because there is of course no mobile-phone (cell-phone) coverage out here. And Lefty, the one-armed mail-truck guy (macabre Aussie humour), he comes out from the Alice on Fridays, calling at every cattle property in our area, dropping off mail and making deliveries.
That same flat tyre night, at the dinner table Dad said. "Tomorrow, Wednesday, I have to drive out to do some maintenance at our East Bore. Lefty spotted a some leaking PVC pipes when he was passing by there. A lot of water will be going to waste."
Precious water that should have been pumped into the big holding tank would be spilling onto the ground, so repairing it was top priority.
Dad looked at me. "Are you up to date with your school work Kris? I'll need you to come with me."
I started to say yes, but Kylie talked over me. "Yes we are! And I'm coming too."
Dad smiled at her and nodded.
Out here in the Mulga it is not prudent to travel very far alone. It is a four hour drive to the bore, as it's half-way in towards the Alice, a few kilometres from the Stuart Highway and a big Shell Roadhouse. Therefore we intended to camp out overnight to have sufficient time to do the repairs.
At East Bore, Dad unhitched the trailer that carried some spare pipes from the rack in the shed, then disabled the windmill to stop the water flow. He and Kylie set up camp, unrolled our swags, started a fire to boil the billy for a mug of tea and off-loaded the food supplies into the shade of the giant water-tank. I made a start on pulling the cracked pipes down. An awkward job because they are just above head height so water kept running down my upraised arms and soaking my clothes, but It was a welcome relief from the heat.
I heard Dad talking, louder than a conversational tone, and realised he was on the sat-phone.
He came to tell me. "I need to go in to the Alice. The parts for the tractor have arrived and we need them urgently to keep up with the cattle feed. I'll leave you two to finish this job. It's easy enough Kris, and Kylie can help. I'll stop over in Alice tonight, collect the parts in the morning and If all goes well I'll be back tomorrow, early in the afternoon."
"Right-oh Dad. We'll be fine." I was pleased to have the opportunity to prove I could be trusted with the job.
Dad finished up with some safety instructions. "I'll notify your mum and I'll tell Lefty you're here in case I run into any problems, then he could pick you up on Friday morning. The spare sat-phone is in the first aid kit. Switch it on now. I'll check in with you later."
After he drove off Kylie came over to help. Soon we were both soaked to the skin, my khaki shirt clung to me making some movements difficult. Kylie had on an old, faded, long-sleeved tee-shirt, that had once been yellow. It became instantly saturated and wonder of wonders almost transparent. The wonder of wonders was that, as usual, she wore nothing under the shirt. The sight of her tiny breasts was very, very interesting to an inexperienced young guy like me.
She chattered away happily. "This is kinda fun Kris. Better than Maths any day."
"Well yeah." I agreed enthusiastically, stealing as many glances at her pointy little titties as I dared.
The nipple bits looked like they might soon pierce the flimsy tee-shirt material. The pink colour of them clearly visible to my sneaky eyes. I was nervous in a way, because sooner or later she would notice the state of her shirt and be embarrassed. She'd probably get angry. Probably at me.
Sure enough, all too soon she looked down and quickly covered her chest with her hands..
She gasped. "Oh my God! Look at me!"
"Uh, I uh, hmm. Yeah."
"I didn't mean to actually look at me!" She was red-faced and nearly crying, "You have been looking damn you!"
"Well I couldn't help it could I?"
"You could've said something. I don't know what to do now. I've got nothing else to wear and you need help to hold these these long pipes up."
"Come on, just get on with the job," I tried to soothe her. "Not much use worrying about it now. I've seen all there is to see, and there's no one else out here to look at you."
Kylie still had her hands over her sweet little breasts. "I dunno..."
"Come on. Grab the end of this pipe. Help me lift it free. Don't worry about that." I looked at her hands clasped over her chest, "I'm your brother for God's sake."
She grinned, teary-eyed. "Being my brother didn't stop you from copping an eyeful."
"Ahh...no I guess it didn't. Anyway you look really good. I've never seen a girl's..."
"Tits!" Kylie laughed. "Oh alright. What the Hell." She reached up to support her end of the long piece of pipe, and her gorgeous breasts came into view again.
"Way to go Kylie!" I wriggled my eyebrows.
