I awoke to a flash of light in my face and a clicking sound, my first thought was Anais but as I opened my eyes I felt her beside me, no that's not quite right, it was more like she had snuggled up next to me, her forehead pressed into my chest and my arm wrapped around her, I began to stroke her hair when I realized what all this meant, I looked up and saw a beaming blue face.

"MOM," I yelled, "did you take a picture of us?" I asked quieter after getting over the initial shock.

"Oh I'm sorry Gummypuss you two just looked so sweet together, oh and sorry we assumed your room would have two beds, not one big one," she said as she began shaking Anais awake.

I grumbled about how she better not show it to anybody and asked how much time we had before we had to get going, but before she answered something even more embarrassing happened, Anais who refused to be awoken at what I later found out was six in the morning, and two and a half hours before we were supposed to leave the hotel, rolled both of us over somehow until she was laying directly on top of me.

At this mom had to suppress a giggle, I asked, "and just what is so funny about this mother?"

"Sorry, it's just I do the same thing to your father all the time and seeing you two like that... It's just really funny to think about for some reason," she said not answering his question to the extent he had wanted her to.

"Eh, I guess you kids can sleep for another hour or so while your father and I get our course charted, but don't you dare try to sleep in," she said with a clear warning in her tone, she then preceded to leave the room locking the door as she left.

I looked up at Anais and realised I didn't mind her being there, not in the slightest, But as an hour came and went somehow I knew I had to wake her up, so I rolled us back over and shook her until her eyes fluttered open, we stared at one another for a few seconds before we both hopped up blushing, and began getting ready for the drive.

(An hour and a half later.)

For the first half-hour or so of driving we occupied ourselves with shaking off any traces of sleep and eating the breakfasts that we picked up from a fast-food place, Not a great start to the day, but at least with our minds on other things, there was very little awkwardness between us because of last night. I took the first shift of driving and once we were both settled in, and Anais dug her mp3 player out of her bag.

"Shit!" she exclaimed. "I didn't even remember to charge it last night."

With a look of disgust at herself, she chucked her bag into the backseat and slumped down in resignation while I chuckled at her misfortune despite it affecting me as well. She crossed her arms over her tank top and glared at me.

"I wouldn't laugh so hard," she said. "It just means I'm gonna need more entertainment today."

"You have your laptop, you could always check out some more porn," I said sarcastically, earning a punch to the arm.

"First off I wouldn't trust you not to crash us if I did that, secondly no internet dumbass."

"Point taken, but you might have had some saved, how'm I supposed to know?"

"I dunno, but the point is, you need to come up with something better than that."

"Why do I have to? I'm not the one who's bored." I said just slightly annoyed

"Because you know just how intolerable I can be if I want to," Anais said with a smirk.

"And you think I can't?"

"Ugh, fine. I'll just try to take a nap or something."

Anais assumed a position similar to the day before, reclining in her seat with her feet propped up on the dashboard. She crossed her arms and closed her eyes, for all I knew she was genuinely going to try getting some sleep. Personally, I was fully awake at that point and didn't think I'd manage it in her place, and as It turned out she couldn't either.

"How the hell did we make it through all those other trips we made?" she asked after only a few minutes of quiet.

"Annoying mom and dad, not to mention each other," I replied. "I believe we actually kept score one year."

"Oh yeah." Anais smiled fondly as she remembered the past trips. "Who knew there was actually an upside to us all traveling together after all?"

"Go figure," I replied

"Still, there must be something we can do, Like, what kind of stuff would we get in the way too much trouble with the parents to even think about?"

"Talking about anal sex like yesterday I suppose."

"Sexy stuff eh? That's something to consider," she said

Anais sat thoughtfully for a couple minutes while I desperately tried to figure out if I should change the subject or not. If it was just talking that was fine, regardless of how dirty it got. If it became more than that, anything along the lines of masturbating together again, I had to decide if I was okay with it. Part of me was simply curious as to what my sister was going to come up with though, which made it hard to really commit either way yet.

"If you were alone in a car with a girl you liked for a while, what would you be doing?" Anais finally asked.

"A girl who isn't you I take it?" I asked

"Well duh, we already know how well that's going," she said crossing her arms in mock annoyance

"That's not an easy question Anais, you're obviously shooting for something we shouldn't do," I said

"Yeah, but you liked what happened last night, didn't you? We definitely weren't supposed to be doing that," she said it in a way that seemed to say that she had liked it too.

Her expression told me she knew the sorts of things I'd imagined, maybe even that she'd been thinking the same about me. It was fucked up, but it was only between us and as long as neither of us objected what was it other than some harmless fun? At least, I hoped it was harmless.

"If you were someone else," I started slowly. "If you were, say, my girlfriend... and we were going to be stuck in a car together for a while... I might try something like getting you to remove some clothing."

"Really? While there are other cars going past? That's a little risky." Despite her words, Anais's lips twisted upward in an interested smile.

"Well yeah, someone might see I guess. But if you, or whoever, slide down in the seat there's not going to be much visible. And if you only strip below the waist you're completely safe."

"Why does it sound like you've done this before?"

"Because I have, When I was with Terri I used to get her to do stupid stuff sometimes, nothing too crazy, and I had to work her up to it, but a couple times I got her naked from the waist down and playing with herself while I drove, I almost crashed once, but it was pretty hot."

Terri would probably kill me if she knew I ever told anyone stories about her, but Anais was hardly going to tell. What was more surprising to me was how I kind of wanted Anais to take me up on the idea. It was the same feeling I'd had last night when I'd wished I could see her unobstructed as she fingered herself. Maybe it had been longer than I thought since I last had sex and I was just getting desperate to the point of seeing my little sister as a viable option for... something, but not sex, there was no way I'd let it get that far.

"So what would I get out of it?" Anais asked. "You get something to jerk off to, what would you do for me?" Her tone was teasing and she clearly expected me to protest at the idea of using her as masturbation fodder.

"Well... to use Terri as an example again, we usually play some kind of game and if I won she had to take clothes off if she won, then she got to come up with something for me to do. It really doesn't work out having equal forfeits when one of us has to drive."

"But if I won I could save it for when it was my turn to drive," Anais said, evidently starting to get really interested.

"Yeah, I guess you could." I shrugged

"So what kind of games?" she asked.

"Sometimes just, like, fifty-fifty things. Like whether the next restaurant we pass is McDonald's or Taco Bell. Nothing complicated. You don't think that would maybe be pushing things too far though?" I asked

Anais sighed. "Yeah, it would be. Kinda fun just to think about though, especially about what your face would look like if I actually did start stripping."

"Probably either a 'holy fuck my sister's crazy' expression or 'holy fuck my sister's hot, could go either way and whichever way it goes you know it'd just push me closer to needing therapy."

"You are a bit of a nutcase," Anais agreed.

"I wonder if it's still considered an Oedipus complex if it's your sister instead of your mother," I mused.

Despite the joking tone of our conversation, there was an undeniable tension building. Anais was really close to going for it, teetering on the edge and waiting for a push, while I simultaneously hoped for that push to happen and for something to distract her.

We kept driving and still nothing happened, the mood slowly dissipating into a neutral silence. Neither of us were willing to commit to anything and so it was left to drift away like so many other unfinished thoughts.

"Taco Bell," Anais said out of nowhere.

"What?"

"We just passed one, that's what I would have picked too."

"Oh. You know it can be anything right? Doesn't even have to be restaurants."

The influence of my sub-conscious on my words was less than subtle as I prodded my sister toward starting a game. I couldn't help it, now that I had spent so much time wondering I wanted to see what was under her clothes. I was definitely a sick puppy, er kitten I guess.

"Well what would you pick?" she asked.

Putting the ball in my court, making it my choice instead of hers. That wasn't helping. If I shrugged and gave a non-committal answer she'd probably leave it alone, at least until she got bored again, but I realized that wasn't what I wanted and all I'd really hoped for was an excuse to blame her instead of myself.

"How about cars?" I suggested, going with the first thing that occurred to me. "If ten red cars pass us before ten blue cars then I win. Or whatever colors you want."

"That's fine, you have red and I get blue."

And the choice had been made. It was something of a relief all on its own actually, and it allowed my mind to move onto strategy. Not that there was much involved in games of chance like this, but obviously certain colors were more common than others. I found myself wishing I could remember which ones they were.

More quickly than I'd anticipated Anais swore and I realized I'd won the first round already, luckily she had no idea I hadn't been counting too.

"I knew I should have taken red," she grumbled.

"Yeah, too bad for you," I said

"So now I have to..."

"Either your shirt or your shorts," I said, trying not to smile too broadly. "Or if you don't really want to, I mean I'm not gonna force you to." She was still my sister, after all, that counted for more than my hormones.

"No, I lost, It was fair," she said blushing

I fully expected her shirt to come off first, but to my surprise, and perhaps due to my suggestion that it was a safer option, Anais actually reached for the top of her shorts once she finally made her decision. She had to struggle a little to get them off while in her seat, but soon enough she succeeded and tossed the now unnecessary garment into the back seat.

"So what do you think?" Anais asked.

She didn't quite look at me and her hands fidgeted together in her lap when until she realized she was doing it and clasped them firmly together. Like any girl I'd known, or even myself for that matter, there was an instinctive need for approval when clothes started coming off, It was a nice thought to not care what anyone thought of your appearance, but it never seemed to go that way in reality.

"It's a good look for you," I said. "I like those panties too," I added

"I bet you do, fucking perv," Anais said as a smirk replaced her nervous smile.

"Says the girl who was watching porn last night in our room."

"You didn't seem to mind too much at the time."

"Whatever. Seriously though, that's pretty hot," deflecting the conversation back to my sister's state of undress.

Anais's panties were the same pink as her fur, not a bright pink but soft and light, I couldn't really see anything other than bare leg and underwear, but my gaze kept flicking to her crotch anyway. I can be easily entertained like that sometimes.

My sister clearly noticed how much attention she was getting from me and toyed with me for a few minutes. She would casually run her fingers over her thigh or open her legs wider then close them again, doing a bad job of pretending like it was all natural movements.

"I want red this time," Anais said once the novelty had worn off a little.

"Fine. Let's do more though, like first to twenty. It went too fast last time."

As Anais started counting again I once again didn't bother, instead of watching both her and the road. I liked the way she acted completely normal once her mind was of her partial nudity, it made the situation even more sexy to me somehow. It was similar to the difference between regular porn and those rare videos where the girls didn't actually seem like they were faking everything... It was more real.

"Ha! I win!" Anais burst out.

I winced and realized I probably should have been double-checking Anais's count, but I didn't think she was cheating me.

"So, do I put my shorts back on or do you just owe me one now?" she asked.

"Up to you, I guess." I shrugged

"Hm, I'll go with you owing me then. I want to make sure I get something out of this," she said smugly

"We probably should switch off of cars though, red seems too popular," I added

"Yeah, it does. What about, like, pickup trucks versus motorcycles or something?" she asked

"Sounds good, I got bikes. First to twenty again if there are no objections."

This time I kept an eye on what was going past, wanting to see more of Anais and also a little scared of what would happen if I lost too many times, a little hypocritical of me maybe, but the fact that I was trying to get my sister naked, even partially, was proof enough that my mental state was questionable.

I was heading toward losing two in a row and I could tell Anais was getting excited when I got lucky and a whole group of bikers went by in the other direction, it was easily more than twenty bikes in less than a minute and my sister let out a heartfelt "well fuck!" as her luck changed.

"Looks like your turn again dear sister," I said with a deliberately infuriating smile.

"Yeah yeah, Lucky bastard."

Anais glanced around seeming to take in how close other cars were to us even though their relative positions would fluctuate. She sank farther down in her seat before starting to pull her tank top up over her head. I had a very hard time concentrating on my driving while her bare stomach came into view, followed closely by her bra, Her shirt joined her shorts in the back seat once it was off, leaving my sister in only her bra and panties.

"Can't believe I'm doing this," she muttered. "Some pervert in another car is going to see me, I just know it, Not to mention the perv in this car who was already looking," she added blushing harder

"No one's going to see anything," I assured her. "Not that you have anything to be embarrassed about."

"Are you saying I'm hot?" she raised an eyebrow.

"I'm saying you're hot, yes."

"Good, 'cause I'd hate to have to beat you up while you're driving," she said smiling

"As if you could," I scoffed. "Plus we'd really attract attention then, me swerving all over the road fighting you off."

"Yeah," she said in kind of a weird tone. "It's funny, it's not like being in my underwear is that different from a swimsuit or something, but it feels different somehow."

"Because underwear is meant to be hidden, you think it's wrong somehow even if isn't really a big deal." I tried to explain.

"If it's not a big deal how come you're getting hard?" she asked softly.

"Fuck off," I growled even though she was right.

I'd been trying to hide it and hope it would go away, but I was definitely getting an erection. It wasn't even like she was naked, I shouldn't have that kind of reaction to her over a little skin. But it was so much more than just skin, it was the knowledge that I shouldn't be looking at my sister that way at all combined with the second-hand emotions I was getting from her, nervousness, embarrassment, excitement, and all from being in a semi-public location without her outer layer of clothing. I was curious if either one of us would be able to handle it if she stripped off completely.

"It's probably kind of bad if we get horny over something like this," Anais said, making an observation rather than giving any indication of having a problem with it.

"You too huh?" I asked delicately

"Uh huh, don't know why, maybe because I think people going by might think I'm naked in here if they see me. My bra's not all that obvious from a casual glance through the window you know."

The off-red of her bra was obvious enough to me, but I took her point on how it didn't contrast with her skin nearly as much as it could have, or the way most any other color would.

Our game went on hold for a while as Anais kept looking out her window, or behind us to keep track of other cars, I tried my best to get my mind on something else and let my erection go down since dealing with it simply wasn't going to happen for a while, but I didn't have all that much success since it was nearly impossible to keep from glancing at my sister several times a minute.

"Is it okay if I..." Anais said suddenly, then stopped and turned away from me again.

"If you what?" I asked

"Never mind."

"Come on, if you what?" I goaded her

"I'm just... it's so weird sitting here in my underwear." I expected her to ask if she could put her clothes back on, and I was ready to say yes since she had done enough it couldn't be considered backing out, Instead she simply said, "I'm getting kind of horny," altho reluctantly and in a quiet voice.

"Oh." was all I could manage.

She didn't come right out and say it, but the only thing that made sense was that she wanted to masturbate. In that context it was odd that she said anything at all. We'd certainly been getting more sexually comfortable around each other, but this just seemed like a step too far, no actually, last night had been as well come to think of it.

I caught Anais squeezing her legs together in frustration the next time I glanced at her and felt a small surge of pity for her, and I was turned on more than I liked from her state of undress, how much worse would it be for her, not only dealing with me, but also the chance that any one of those drivers going by might see her too.

I sighed deeply, "Go ahead." I said simply.

Anais raised an eyebrow and looked at me assessingly.

"You think you could keep us on the road if I did?" she said, only half-joking.

"Pretty sure."

I was worried she was going to think I was just being a complete perv, which I sort of was, but my offer was at least partly a genuine attempt to help her out.

"What the hell," she said after a brief pause.

I really wished I wasn't driving at that point. Anais abandoned all pretense of restraint and slid her hand under her panties, letting out a long sigh of relief as she finally got to ease some of her tension. I had neither a good angle nor the luxury of being able to focus on her as much as I wanted. Perversely this might have gotten me more worked up than if I'd been watching intently since my mind had to fill in so many of the gaps, and did a pretty good job at that.

For several minutes all I heard was the sounds of my sister working her wet pussy and her increasingly ragged breathing. The smell of sex slowly permeated the car, and combined with everything else was enough to very nearly make me lose it.

Finally Anais hit her orgasm, her legs stretching out as much as possible in the space she had while a small, sexy moan escaped her lips. She slumped back in her seat as she finished and gave me a sheepish grin.

"Sorry 'bout that," she said. "Though I don't think you minded too much somehow."

The tent in my shorts was all too obvious, and I'm sure there were other signs that gave away what I was thinking.

"Well, it's over now anyway." I shrugged.

"I guess. Must be my turn to drive soon."

I had no idea how long I'd been driving, I couldn't even seem to manage the simple math it would have taken from looking at the clock on the dashboard. I could sense Anais's ulterior motive for offering to take over, but I had no intention of fighting her over it.

At the next convenient opportunity I pulled over and got out of the car to switch seats. Anais stayed in the car and simply hopped over to the driver's seat while I was walking around, apparently content to remain half-naked. As I sat back down I noticed a damp spot right about where her pussy would have been.

"Seat's a little wet," I commented innocently.

"Shut up!" Anais blushed, an adorable reaction given what she'd just done, and flipped me off when she caught my smirk. "And don't you still owe me?"

"Yeah, I do."

I had only started to take off my shirt when Anais stopped me.

"Uh uh, shorts," she said, pointing helpfully at my legs.

"Hey, you got to pick what you took off."

"Yeah, but... come on, that's not fair."

"Sure it is, I won two to your one."

"gumball, don't be an asshole about this. Please. I thought we could... I don't know. I let you watch me and everything, that's not something I do for a lot of people."

I was planning on giving in anyway, but hearing my sister come very close to getting upset with me made refusing even less of an option. The last thing I wanted was for her to be mad at me now.

"You're right," I said. "I did get to see more than I should have strictly speaking."

"Damn right."

Her expression of annoyance turned to anticipation as I slipped out of my shorts. I had boxers on underneath and they did a much worse job of hiding my erection than my shorts had, which wasn't saying much. Still, the way Anais's eyes widened as she saw the way they tented over my crotch almost made it all worthwhile.

"Happy now?" I asked.

Anais shrugged and looked away for a moment instead of really answering, but I could tell she must have been feeling the same sort of guilty fascination with my body that I was with hers.

"Guess you really liked watching me," she said quietly.

"Yeah, I did. Fucked up isn't it?"

"Pretty much." She smiled, then chewed on her lip briefly. "You could... take care of it too if you wanted. I mean, I did already so it's not like it's any worse than that."

"You'd probably be able to see more than I could," I pointed out, not that it was going to be enough to dissuade me since I needed to get off really bad.

"Your choice."

She acted casual, or tried to, but she couldn't completely hide her interest. We were both too far gone to pay enough attention to our calm, rational sides.

Wordlessly I reached under my boxers and gave my cock a long, slow squeeze. It felt so good to finally be able to touch it, when I was as turned on as I was I didn't think I'd ever held back for so long. The confines of my underwear were usually not ideal for masturbating, but I wasn't ready to whip it out in front of my sister just yet. It wasn't exactly going to be one of my longer sessions either.

While Anais had joked about it earlier, I really was worried a couple times that I was going to distract her to much and we'd crash. Luckily we never did, but her eyes were on me, or rather the outline of my rapidly stroking hand, as much as she could manage. Knowing she was watching me so intently was both embarrassing and strangely arousing.

After a few minutes I was getting ready to cum, images of my sister firmly at the front of my mind as I did. It was going to make a huge mess of my boxers again, but I was beyond caring. I just hoped I didn't run out during the trip and have to get them cleaned somehow.

My orgasm marked the release of all my pent up tension and allowed me to sink back into a much calmer state as I finished. I felt an incredible contentment, not nearly as concerned as I should have been over what Anais and I had just done together. In fact, I probably spent more time thinking about what else might happen between us than worrying about what had already p assed. After all, we were going to be sharing another room that night, there was no telling what that might bring.
