A few summers back, I had returned from finishing my freshman year in college, and my younger sister Jane just turned 18 was just finishing her senior year in high school. Since we were little kids our family would often visit naturist resorts, so this family weekend was nothing out of the ordinary. The cabins on the resort were a little run down, so the last few years we decided to rent a cabin a 30 minute drive from the lake.
Jane and I were always close growing up, separated by just one year.
A day at the nudist resort
Having been to nudist communities before, seeing her naked was nothing out of the ordinary. She had always been smaller, skinny and athletic a bit of a tom boybut seemingly out of nowhere her breasts grew to at least a C or D cup and her body into much more of an hour glass figure.
On this particular weekend, Jane and I were smitten by the fitness bug. I was trying to get in better shape for the girls at college, and she was about to go to college hoping to make the track team. The first morning we decided we would bike to the lake from our cabin, which took a little more than an hour.
When we finally got the lake, we immediately stripped down but decided to keep our fitness kick going and went for a long run and swim. We felt like naked triathletes it was great! After our hours of working out, we met our parents on the beach. They drove down and brought an enormous cooler full of picnic snacks, and some drinks!
It was the perfect way to follow up an entire morning of working out! We ate, drank and relaxed completely naked. As the late afternoon rolled by however, our dinner plans back at the cabin drew us home before sundown.
We also HATED putting our clothes back on after the lake, and were used to driving home naked and spending the rest of the night nude at home. No Chance! I suggested we put the bikes in the trunk and drive home, but my Dad insisted that would be impossible to fit into our modest Toyota Camry.
Jane and I exchanged naked looks and we both knew how awful that bike ride home would be, so we set out to solve the issue.
However, my Dad was quick to point out the massive cooler they had just packed up, which also had to fit into the car. My sister smirked at me, proud of the success and avoiding the painful ride home.

The final issue was the back seat barely had room for me to sit, let alone my sister! At this point however, there was no turning back so the only solution was for me to take the back nudist and Jane to sit on my lap. My parents expressed some safety concerns, but Jane had no problem and insisted we do it. At this point we were dead tired and just dying to get home. So we were off, driving down the country ro story my parents fully clothed and fastened in the front, while my completely nude sister sat on my lap in the back.
Still, the whole scenario seemed completely normal to Jane and I, and we just chatted away as normal. About 15 minutes into the drive, the sun had almost set and we all became drowsy from the busy day. But suddenly, as we began to drive on the bumpy country ro, I felt something unusual… A rush of moistness spread on my lap. It took me a few seconds to realize what happened, but it was adult very quickly, and I think Jane realized too.
We were dead silent. I could tell that she realized what happened, because she shifted her weight on lap awkwardly to attempt to make her wet vagina less obvious. A minute later I felt even more moisture, now on a different part of my lap so it was even more obvious! My sister was getting incredibly wet, and it was all over my lap. She shifted her weight again, and that again made it even worse. I was trying to imagine it was just her body sweating, but I had Goosebumps from the cold air conditioning in the car.
There was no question Jane was getting wet all over my lap.
She moved one more time, and I tried as well, but we were so nudist back there it accomplished nothing. In fact, it made it much worse. I knew she was accidentally aroused, but now I was doing everything I could to stop myself from getting hard. I shifted to sit more upright, but my hands were trapped on her lap and to her side, so the position.
The more I thought about the scenario, the more difficult it became. She shifted one more time, and sure enough, I could feel the blood rushing to my story I tried to slump back in the seat but there was no stopping it. As my dick began to push against her, I looked to see my Dad driving right in front of us. Luckily and he was listening to the radio and focused on the road, he never noticed the awkwardness in the adult seat.
It was hard to tell from the angle but my Mom looked sound asleep to the right of us. Jane and I remained dead silent, and I was about to be rock hard.

Then it happened. Jane uncomfortably shifter her weight on my lap once again, and I tly tried to sit upright again. My cock was rock hard. As soon as Jane felt it she perked up, and did her best to lift her weight off my lap. The head of my dick was pushing right on her, and there was no way either of us could ignore it.
I could tell she was doing her best to lift herself higher off me, but we were so crammed there was nowhere to go. Her moist pussy kept juicing all over my cock, and we sat in silence awkwardly, looking straight ahead. It felt like an eternity. I had my eye on the car clock, and figured we were probably only about 5 minutes from our cabin, so thankfully the end was in sight. But the more I thought about the situation, the more I continued to be rock hard. And I know Jane felt the same, because her vagina was only getting more and more moist.
Jane was still trying to keep her weight off my rock hard penis for a few minutes. But then, to my utter surprise, she did something shocking.
She moved one hand off her knee and placed it on top of mine placed her other hand under my leg, and twisted her head sideways to catch my in the corner of her eye. She smirked, and then she pushed down on me firmly.
I felt the tip of my dick slip right inside of her. My jaw dropped, and I could not believe what was happening! She looked straight ahead again, lifted herself slightly off me, then pushed down firmly again. I went in even deeper this time.
I could not believe it. In my freshman year at college I had my share of unprotected sex, and knew how everything worked and felt.
Jane pushed down again. And again. Slowly, discretely, but very methodically.
I could NOT believe that I was inside my sister, and she was going for more! Even more crazy was that our parents were in the car right in front of us, completely clueless. After about 5 or 6 thursts downI knew I was going to cum at any moment. She lifted herself up a little higher and prepared for one big push down. But in doing so, she pulled herself a little too far up, and my cock slipped out of her wet pussy. So we sat there nudist my fully erect cock about to burst, right in between her wet upper thighs. After about 20 seconds of awkward confusion, Jane clenched my hand tight, and used her other hand to tuck my cock back up into her.
And that was all it took. Two quick pumps and I ejaculated story inside of her. To my horro both my parents noticed! Thankfully Jane played it off as if adult thought popped into her mind. Less than a minute later, we pulled up to our cabin.
