After our energetic afternoon and a few hours of unsuccessful fishing I decided to take a break and go for a walk to stretch my legs. Our little fishing, fucking spot felt somewhat claustrophobic right now since I was most definitely unaccustomed to any form of company or sexual activity while on a fishing outing -- it was a shock to my system!
If it came to that, apart from my wanking moments and my few trysts with other girls, I just wasn't used to having sex so energetically or so often, regardless of how much I'd just enjoyed our activity. My outings were usually quiet peaceful events but if my sister was to be part of my days out I was going to have to get used to a whole new world and I needed some space to think. Oh, no way was I complaining about the added excitement of sex and of incest but I did need to do some ruminating to ascertain in my mind that having sex with my sister was to be an acceptable activity in my future life.

I stood up and stretched, noticing Sharon watching me closely, then picked up my shorts and t-shirt, shaking some bits of grass and a few errant leaves from them as I did so.
"What're you up to?" asked my naked sister.
"Just want to take a walk but I suppose you want to come too, don't you?" I said as I began pulling my clothes on, then stepped into my shoes too, "Just round the lake a bit."
"Yeah, I'll come; don't leave me here!" she wailed, her arms stretching out to me, "I don't like being left on my own!"
I heaved a deep sigh of resignation, having hoped that she'd want to just lay there and sunbathe but now knowing that I'd have to put up with her on my ramble.
"Oh come on then if you must," I said, "Only because it's you, but mind you, I don't know how rough the path will be."
Sharon stood up and plastered herself against me with her firm naked tits squashing themselves deliciously against my arm and, easily beaten, I finished dressing and after a quick kiss Sharon began to do the same.
"I don't care, so what, you'll be with me," said Sharon suddenly happier again as she dressed, "I'd get all scared if you left me there alone."
Once we were both suitably clad I led Sharon along the side of the lake, the pair of us following a small and windy path that various animals must have created, stepping over fallen logs and pushing aside overhanging branches as we moved on. I'd been this way before but only as far as a small point that jutted into the lake but from there on it would be genuine exploration for us both.
"Which way now?" I asked quietly once we reached the end of known territory, but Sharon only shrugged her shoulders so, as leader of our little outing I opted for the uphill path.
We trudged on quietly for some time but there were only the sounds of nature around us -- it was silent otherwise.
"So quiet, so peaceful, isn't it?" murmured Sharon and I smiled at her, acknowledging that she was seeing the world from a very different aspect to her usual haunts.
"That's what I like about these forgotten places -- you're on your own with nature," I added as I paused and looked around, "It's lovely."
"On your own with nature except for me," said my sister as she closed up behind me, "Just us two."
"Mmmm yeah," I said, enjoying the ambience but hardly listening to her, "Peaceful, I agree."
We moved on, climbing steadily, our path now through wider spread trees and more grass but still very much alone. We spotted numerous birds and a small herd of deer rapidly departing but nothing to cause us any alarm and certainly nothing to disturb us.
The sunshine and the climb made it hard work and before long I could feel the sweat starting to break out and knew that a pause would be appreciated.
"Do you want to take a break?" I asked as we left the trees behind and approached the crest of the hill.
"Ohh yeah, what a good idea; hey, over there, on the grass," panted Sharon as she stepped up close behind me once more, her breasts pressed softly against me as she stood there, "Come on, stay with me."
On the sunny slope not far from the top of the hill was a patch of short rabbit-nibbled grass and it was there that Sharon now let herself down onto the ground. She pressed her hands into the soft grass and sighed contentedly and then, as she saw me removing my t-shirt she took off her own top as well.
"Ohhh, that's lovely," she sighed as she lay on her back, "Nice...all soft and springy."
"What -- your tits?" I asked with a small chuckle but instead of a more usual retort from my sister she smiled, wobbled her breasts at me and blew me a kiss.
"Well yeah, and those!" she answered with a wink.
We were silent for a little while as we gathered our breath and strength again, until Sharon spoke.
"Now then, what do people do when they're on their own?" she asked, as she rolled over and lifted her head on one elbow to look at me.
"Ummm, relax I guess," I answered as I enjoyed the views around us.
"No, not when I'm out and about," said Sharon, "When I'm out alone with a guy we usually get busy."
"Busy?" I asked as I sat up, my mind not focussed.
"Yeah, busy fucking!" said Sharon eagerly, "Come on, let's do it again!"
"What -- again?" I asked, still shocked.
Even as I spoke she was casting off her shorts and shoes and before I'd even thought to undo my shorts she was there, laying back and lifting her pussy up to me.
"Come on Chris, you've got me all hot with all that walking," she said as she stroked her hand up and down her pussy, "What's the matter?"
"I wasn't expecting to," I said but Sharon wasn't to be ignored.
"Oh don't be silly," she said eagerly, "Here, let me help."
In a moment she'd rolled over, pushed me down onto my back and with a few well-rehearsed movements she had my shorts off and my cock in her hand.
I was aroused of course but far from hard but I soon stiffened up as her hand stroked me firmly.
"That's better," she enthused as she wriggled around until her face was poised over my penis and her breasts were pressed against my thighs.
