All of us were bored to death. Looking at my phone, I confirmed that we had spent seven hours in the car today. And still had at least four more until we would reach the cabin. I looked at my sister on my left, and she was looking out of her window, her expression almost zombie-like. Mom was sleeping in the front seat and Dad was driving, but neither of us felt like talking. We were all at that stage where all we wanted to do was grind this drive until it was over.
All except me. Looking at Carrie again, making sure that she was looking outside, I glanced at her breasts one more time. Well, stared was the better word. I was pretty sure that she knew I was looking at her, but for the past four hours she simply stopped caring. At first, when I would look at her, she would turn her head, forcing me to look away. But for a long while now, either she didn't see me or was too listless to bother.
Looking at her was the only thing preventing me from going crazy with boredom. And even after all those hours, I was grateful for her choice of clothing. Carrie had chosen to wear a close-fitting summer dress, a single, strapless piece of thin and stretchy fabric. When I had seen her wearing that this morning as she came out of her room, I had paused and gawked at her: it was remarkably sexy. It had clung to her every curve and even my dad hadn't been able to repress a double take. Before he'd been able to say anything though, my mother had said "Oh, I wish I had such a dress for today..."
My dad and I frowned at the comment, puzzled. Many hours later, very uncomfortable in my jeans and shirt in the car, I understood: Carrie was as naked as she could be and was probably more comfortable than any of us. Nevertheless, it was still a very sexy dress, and my sister was filling it wonderfully. My big sister was a year older than I was, at nineteen, and ever since she hit fifteen, her body had begun to transform. She was now the most stunning high-school senior, and despite being her brother I couldn't not notice her body.
Staring at her in the car, I marvelled once more at the size and curves of her breasts. A forbidden search of her lingerie drawer a few months ago had revealed that most of her bras were in the 32 and 34 range, with cup sizes ranging from D to F. I had a feeling that the smallest, 32D, was an old bra that probably didn't fit her very well today. I remember masturbating shamelessly over that opened drawer, enjoying the smooth feel of her bras and panties on my cock. While part of my mind had wanted to paint the entire drawer with my sperm, I had refrained and came in my hand.
Right now, I could see the uppermost fringe of a snow-white bra peaking from her cleavage. I spent long and delicious minutes staring at every square inch of her breasts and at every inch of each line, from the ones defining her cleavage to the outer contours. I could see many hints of the bra's lace through the dress's fabric, as the otherwise smooth surface had small bumps.
Enjoying this long voyeur period, I let my eyes slip down to my sister's thighs and my eyes opened wide as I saw that her dress had ridden up really high. It was normal, I assumed, that it would only creep upwards as she moved on her seat. But now it was very high... From my point of view, I could see that the dress had been pulled backwards all the way down to her ass, and I could see parts of her hip! I'm sure that if I were sitting in mom's place and turned around, I would see her panties. But I wasn't, and so couldn't, but I was nevertheless granted a very good view of my sister's sweet thighs.
And while Carrie's legs weren't as stunning as her breasts, they were sweet nonetheless. Carrie wasn't all that tall, but her legs were probably a bit longer than normal if her long smooth thighs were anything to judge by. As I stared at her flawless skin, I smiled, enjoying the long gentle curves and firm muscles. I couldn't see her muscles right now, but given how much cycling she did in the summer and skiing she did in the winter, I knew and could see that her thighs were firm.
It's strange how a dress can change things. I had seen my sister wearing bikinis many times, and was already familiar with her thighs, more of them than were currently visible. But the fact that her dress had ridden up so high made things a lot sexier. The human mind is a strange thing when it came to sex: a bikini bottom would have allowed me to see more skin, but that high hemline, trapped in the bend between her thighs and belly, was somehow a lot sexier. Right now, I didn't care about my mind and sex. All I could think about was my sister's sexy body.
Carrie suddenly moved to stretch her arms and yawn. While I briefly glanced at her breasts as she did, I had to turn away. After a long sigh, she said "Dad, can you change the radio station please?" He nodded and fiddled with the stations for a bit. "No, not that... not that either, that's boring!"
After that, dad turned around and said in a low voice, "Why don't you change it yourself... Just don't turn the volume up, mom's still sleeping." Carrie sighed again before answering "OK."
She then unbuckled herself, leaned forward and reached for the controls before almost falling between the front seats. Carrie laughed at her own drowsy clumsiness, and leaned forward more to get better access. And that's when I saw it. Carrie had probably forgotten about her dress, about the way it had ridden up with the hours. When she leaned forward all the way, I couldn't help but look at her ass and felt a twinge of pleasure at the thought of seeing her panties.
But I didn't see any panties. It wasn't because her dress had slipped back down. Not at all. In fact, it was so high from the back that not only could I see that she wasn't wearing panties, but I could also see her pussy. A foot away from my face. Carrie had taken the comfort issue seriously, not even wanting a pair of panties to bother her. I was thus graced with a premium view of my sister's ass and pussy. My jaw dropped and my eyes widened as I stared hungrily.
While her ass cheeks were remarkable, my eyes were inevitably drawn to her pink pussy, large lips and puckered little asshole. Carrie shaved, obviously, and I could see every detail and fold of her delicate small lips as they peaked from between her large lips. When Carrie shifted her weight to the right, I saw her pussy shifting slightly, her small lips slowly sliding against each other. It was surreal, not only getting to see her pussy and seeing it in such detail and from so close! Up until that moment I would have killed to have a hazy video of her naked, and now I was granted an ultra HD first row and first-class show!
Sadly, as soon as it started it also stopped. From what my overwhelmed brain could gather, she had remained like this for about fifteen seconds, but I knew it would be seared into my mind for a long time. When she sat down and looked at me, she was puzzled by my expression and asked, "What's up with you?" I mumbled something noncommittal and hoped that she wouldn't see how flushed I was. When I looked down at my lap, I also hoped that she wouldn't look there and see my hard cock making a tent in my pants. If I had chosen to wear very light gym pants, I would have had a huge, unmissable tent there. For the first time in hours, I was glad to have chosen a pair of sturdy jeans.
Carrie decided to drop the subject and leaned against her window, looking outside. I tried to move my cock to make it less obvious, but soon abandoned. It was impossible to do it subtly, and I didn't want her to see me playing with myself! I willed myself not to look at her again, but mostly failed. I forced myself to look out my own window, but often enough I would steal glances at her thighs.
About five minutes later, I noticed that every time I looked out of my window, she would try to rearrange her dress. I smiled at first, finding the coincidence funny: we had almost the same problem. I even played with her, turning my head away from the window unexpectedly. I didn't look at her, but I could see, from the corner of my eyes, that she froze when I did. A while later, I could see that her dress was now properly lowered, covering most of her thighs. The show was over.
And then it hit me: if she rearranged her dress, it means that she had realized that it had ridden way too high. Maybe when she sat back on the slightly cooler seat... But then, if she had felt her naked pussy on her seat, she probably realized what I had seen while... Shit! She knew! I looked at her and she looked back, but while she still had that bored expression, I could also see that it wasn't the same expression as earlier. She fucking knew! When she asked what I wanted, I shook my head and looked away. The mere fact that she didn't ask again, but simply let it slip by, confirmed it.
I was now flushed as I looked outside, unsure of what to do. The silence stretched out, time passed and eventually I accepted that we simply wouldn't talk about it. A while later, my mom was awake and she suggested that we should stop for a real break. My dad said no, but Carrie and I almost cried our "Yes!" and he was overruled. The next rest area happened to be abandoned, but we didn't care much: the summer day was glorious and we decided to spend half an hour there, walking about in the forest.
Mom and dad stayed together, but Carrie and I went our separate ways. I walked in the woods for twenty minutes before heading back, and enjoyed the solitude. Of course, I couldn't help but think about Carrie's pussy, the details still exquisite in my memory. I walked around with a relentless erection, but given that I was alone, I didn't care. Walking back to the rest area, I tried to clear my head and get the blood out of there. I almost succeeded. Almost.
