Forest walk

Hi guys my name is Ben and at the time of these events I was 19, my sister Beth (not our real names) was 22.

Beth and I still enjoyed going for long walks in the countryside, or forest parks, our father had passed away 2 years earlier and it was his love of the countryside that got us hooked on it.

Now this particular day it was late autumn the leaves had fallen and the wind was cold. But the sun was shining and Beth and I decided we would take a walk in a forest park about 40 minutes away by car.

We parked up and started the long walk along the track, it wasn't particularly challenging, but with cold wind it certainly cleared the head and you felt alive again, living in the city can feel very overcrowded at times, and out here you feel free again.

The track went round in a loop and took roughly 2 hours to complete,about half ways round there is a river that flows along side the track for some distance.
When we reached the river we noticed that one of the nearby trees had fallen over the river making a bridge to the small island on the other side.

Beth suggested we climb across the fallen tree to the island I was reluctant as I knew it would be dark soon...but as Beth pointed out as children we often went to the island with dad....you see, there used to be a foot bridge across the river, however a few years back it got washed away in a storm.

Anyways I foolishly agreed and we climbed up onto the fallen tree, it seem stable and when we were almost across the bank on the other side collapsed and the tree along with Beth and myself fell into the river.

We floated a short distance and thankfully the tree got wedged, which allowed us to hold onto it and climb out of the river back onto the track

We immediately felt the cold, we were wet to the skin and were a good 40 minutes from the car. I searched for my phone but it was lost. Beth had her phone but the water killed it, however still had the car keys.... .

We started up the track towards the car as fast as we could the cold was biting us hard and every muscle in our body wanted us to stop.....after what felt like ages we got to the car, by now it was dark and we were shaking and shivering uncontrollably....Beth pushed the button on the key but nothing happened, the car did not open, she tried again but no luck....she then stuck the key in the door handle and turned the key a finally we got into the car.

"Start the car Beth"....she stuck the key in the ignition turned it but nothing, tried again but this time......Key error came up on the digital display...the water had done something to the key, and the key and the car were not communicating, apparently I found out afterwards it's was an anti theft thing.

I could she Beth was now looking really bad she was so cold, I said we both need to get out of these wet clothes....no way replied Beth.....listen Beth the wet clothes are pulling all our body heat away and if we stay in them we will probably die....

Well Beth listened and I was saw my naked sisters body for the first time since we were children....she looked amazing her long ginger hair and blue eye, with fantastic tit's and her nipples hard....she genuinely had an hour glass figure and her ass was absolutely gorgeous, but I was to cold to really care about any of that.

We climbed into the back seat I wanted to spoon against her, but she said..."no way mister, face to face so I can keep and eye on you"....though chittering teeth and she smiled.

So Beth was laying on her right side facing the drivers seat, I on the other hand was laying on my left side with my back to the drivers seat....we were face to face, chest to chest and completely naked.

It was the first time I noticed how slim and tiny she was compared to me....I'm 6'1" and she was only 5'5"....I reached past her and found a picnic blanket pulled it over us in the hope we might warm up.

Eventually we both stopped shivering and started to warm up slow,by now it was dark and frosty outside the car, the only light was the moon that meant we weren't in complete darkness.

I guess at some point we both fell asleep and when I woke I found that Beth had lifted her right leg up onto my thigh, and of course being a man I reached down and discovered that this had left her pussy completely exposed and very accessible

I softly started to rub her pussy and play with her clit and in doing so got myself somewhat aroused, my cock was now very hard and leaking pre cum....and again being a horny teenager I rubbed my cock against my sister now wet pussy, further lubing her up as I continued to rub her cunt with my cock it would slip in her a little, but I quickly withdrew myself.

That is until Beth opened her eyes, and looking me straight in the face whispered "what are you doing Ben".....with that I kinda jumped and my entire cock was now in my sister Beth's pussy......"Oh my god, oh my fucking God Ben what the fuck are you doing"????......"This is soooo wrong Ben"......"I know Beth but you feel so Good"........"well in that case don't fucking stop"

Well I kinda froze looked at her then....thought holy fuck...with that I buried myself balls deep in my sister....she moaned out loud..."don't you fucking stop"
I laid her flat on her back and pushed her legs apart, again in one brutal thrust I buried my cock deep in my sister pulling back then slamming hard into her....any resistance left in her legs was soon lost as I continued plowing my cock deep within my sister....her legs grew weak and soon I had her knees pushed high up either side of her...

As I thrust into Beth her tit's moved in rhythm to my cock, finally I bottomed out in her hit hard against her cervix....she yelped as my cock continued it's assault on her cervix, forcing it to yield, preparing it to accept my seed. Beth was now begging me to keep fucking her, she was shaking uncontrollably...this time from her cumming over and over....she was spent, done, completely weakened...and had resigned to the fact she could only lay there and let me do as I wished.

Under my hugh frame she was nothing more that a rag doll to me, my cock pushing to depth that had never been reached before, I watched as my cocks girth stretched her pussy as I pulled back and slammed into her pussy gripped my cock...mmmm
I needed to cum and Beth knew I was about to....."Ben don't cum in" she said quietly......shhhh Beth it's okay....as I slammed in one last time pushed hard against her cervix...I unleashed my seed rope after rope of cum floated her pussy filling her that much she couldn't contain it all.....
As I pulled out a stream of cum flowed from her gapping pussy...I lay on top off her...telling her we would be doing this again....she smiled and said " yes please, but I'm on top next time"
