A brother and sister get a bit closer on a long car ride stuck together.


(This is part 1 from an ongoing F-List RP.)

Cartesian had always taken after her mother in the looks department. Unlike her darker furred brother, she was a white and chestnut brown mare, with longer hair she kept in a side plait, usually draped on one shoulder. She was about average height for an equine, and at 16, growing rather beautifully into her body, although she was probably the last to realize it.

"Uh... I think we over packed," she said looking at the family cherokee. The passenger seat had two bags wedged in, the middle bench had food, a cooler, some of the camping supplies, and the only real space besides the driver's seat was the cramped back seat. "I'm... not unpacking any of MY stuff. We're going to be gone for 8 weeks and I'm already down to as light as I can be on clothes!" she complained.

The three of them, Cart, Drake and their mother, Kirah, were supposed to be heading for a summer family reunion, but they were looking at a 9 hour drive before they even got to the ranch.

Drake was far from thrilled with the entire situation either. Of the three of them, he was the lightest packed. Some extra underwear, shirts, shorts, a pair of jeans, and a single hoodie were the only clothes that he brought beyond what he was already wearing. Stuff could always be washed, after all, and he wasn't terribly concerned about fashion. "Don't look at me, runt. Only one of those bags is mine, the rest is all you and Mom." Unfortunately, he knew that neither one of them would be willing to lighten the load. The food and camping gear couldn't be ditched, after all. "So unless you get rid of some of that, how are we supposed to all fit in?"

"Can the two of you quit kicking the dirt and hop in? We need to get a move on if we want to make it before sundown!" their mother said. The tall mare was wearing a plaid shirt and tight jeans, walking right past the two of them to the car. Her tail gave an annoyed swish. She had won the unofficial prize for 'most things packed' and wasn't in any mood to rearrange things. "What's the hold-up anyways?" she asked as she opened the driver's side door.

"Mooommm! There's like, room for one more in there at most, and that's all the way in the back! Unless you want bro to be riding on the roof rack, I don't see how we're going to fit all that stuff and US!" Cart answered.

Pausing, their mother looked at them, and then at the car, poking her head in over the seat and looking at the mountain of stuff. She offered a whinying snort. "There's plenty of room in the back. The two of you can make do. You're family, being close never hurt anyone," Kirah said hopping into the front seat and starting the jeep cherokee up. She rolled down her window and clapped the side of her door, "Hurry it up." To her, the matter was already settled.

It was already May, and given the temperature, Cart was wearing a simple short summer dress with spaghetti straps over a pair of knee high boots. Her ears flicked about in annoyance, and with a frown she looked at her brother, already stomping over to the back side of the car.

Drake answered her frown with one of his own. The siblings could already guess that this was not going to be a pleasant trip. "Whatever," he grumbled as he opened the door before her and climbed into the back seat. The stallion scooted over as far as he could, trying to make room for his little sister. Sure, they'd be squashed against the gear and the door respectively, but maybe... just maybe... they could manage to both fit in that way. "Come on, brat. Get in. The sooner we get going the sooner we'll be done with this." Of course he thought that his mother was crazy for trying this in the first place, but what could he do about it? He certainly couldn't talk back to her without making things worse.

With an indignant huff, Cart got in, pulling her dress under her legs and trying to scoot into the seat next to her brother. It didn't go over that well, as the seat was obviously not spacious enough for the two of them. "Mooom...." she grumbled.

"Just get in, we're going to be late."

Slumping her shoulders, and muttering 'fine', she just hopped up and bounced right into her brother's lap, the only way she'd manage to get herself in the car and shut the door. "You're a pillow for the ride," she said a little snidely at him, unable to believe this was going to be 9 hours. She got the door shut, and tried to adjust her dress and get comfortable, unintentionally worrying her bottom against her brother's lap. "I'm in, door's shut... happy now?" she asked tursely of her mother.

Drake was too irritated at the situation to realize the danger of having her seated in his lap. It was just uncomfortable, to say the least. "Great... I've gotta have your big butt crushing me for the entire trip. Alright, let's just get this over with, then." Of course, his comment was just typical for sibling rivalry. He didn't believe that her butt was big, nor did she ever seem to take his words at face value. With no other outlet for it, it was just his way of expressing his frustration with the situation.

Before long, they were on their way. Drake's grumbling was kept to a minimum, the radio was playing some classic rock, and their mother's focus was on the road. So long as the siblings weren't killing each other, she didn't even bother to glance back at them.

The first hour was fairly uneventful, the roads were clear, and they were leaving their sparsely populated town. The biggest problem was as they started making their way to the interstate. Outside of town, the road was not well cared for. Cart had already shifted around in her brother's lap a bit, sitting on a non-cushioned uneven surface got increasingly uncomfortable and after continually trying to adjust, she hadn't realized that her short dress had ridden up and her silky black panties were right over his lap.

A sudden dip in the road jostled the passengers and cargo. "Hey! Watch it mom!" Cart called.

"Pothole, I'll try to avoid them hun."

Drake found the way that his sister's rump was bouncing in his lap uncomfortable, but the male was otherwise oblivious. He hadn't noticed that her dress had hiked up in the back. His body's reaction, however, was much different. Instinctively, it was well aware that there was a nice, round female rear that was grinding down against his groin and when they hit that first pothole, bringing her butt bouncing off of his shorts-clad sheath, the member that it contained twitched. "Please do," he piped in, "before her bony butt breaks my leg." Bony butt? The male didn't realize that he couldn't even keep his insults straight.

Frowning, Cart purposefully leaned forward a little and pushed her ass down. She hadn't felt the twitch as they'd been bumped. "Does that feel bony? You just have a fragile lap! If you break anything it's just cause you're dumb," she said in her own defense. She bounced in his lap half a dozen times to try and prove her point and 'fight' against what she deemed an insult.

Drake felt her rump repeatedly press down against his groin and, in response, his sheath twitched again... and again. He couldn't ignore it this time, but he couldn't admit it either. "Cut it out, brat," he warned her, "if you ever want to be able to sit down again." The damage had been done, though. Even with their mother avoiding the potholes, the road was far from smooth. He could only hope that his little sister didn't realize that he was slowly, but steadily, growing hard beneath her firm rear.

Cart smirked, counting that as a win. She settled down, frowning slightly as his lap seemed even more uncomfortable. She shifted in his lap a little, trying to find a spot to be comfortable. It didn't help things at all, her ass cheeks rubbing one after the other over his firmness, before she was finally able to settle unintentionally hotdogging his member between her cheeks. "Can you like stop moving around so much? It's getting hard to sit straight," she said, thinking it was just his shorts riding up or something.

Drake wisely kept quiet, not wishing for her to realize the truth, but unfortunately that didn't seem like it would be enough. As she wiggled about on his lap to try to get comfortable, his member continued to twitch and grow beneath her. The male's sheath was thick and plump and, as his shaft grew, his shorts were becoming uncomfortably tight. As fate would have it, the car hit another pothole, slamming her rump down on him so hard that it was evident that it wasn't just a fold in his shorts that she was sitting on. Their mother quickly apologized, but she hadn't realized just what it was that she had done.

As Cart bounced in her brother's lap once more, gritting her teeth at the jarring movement of the car... she felt something distinct from the shorts hit her panty clad ass. Her eyes widened a little bit and when the car had finished its bounce, she knew, distinctly knew, just what was going on now. As she focused her mind to what was happening, she could actually feel it twitch and pulse a little beneath her and she suddenly got as silent, pretending for a moment that nothing was happening and that she was imagining it. Her mind played a few scenarios in her head of what things it could be besides her brother getting hard under her... but they were quickly dismissed as things got more obvious. To make sure she wasn't imagining things that weren't there, she wiggled her bottom the tiniest bit more. "That's not... what I think it is... is it?"

Drake's member didn't just twitch this time, it throbbed. Despite just how obvious it was, the elder sibling pretended not to know what she was talking about. "What, what is?" he questioned. His heart pounded in his chest. Gods, he was mortified! Worse yet... what if she said something? What if their mother found out what was going on? He could only imagine the suffering that would happen then.

Cart wasn't stupid. She looked at her mother and bit her lip. Drake was embarrassed, it was an accident then. Hell, she was embarrassed too... he probably couldn't help it and to a point, it made her blush a little as an unintentional compliment. "Nothing, forget I said anything," she said in a quieter voice, deciding he had the right course, just to pretend it wasn't happening. She tried to steady herself, keeping perfectly still so not to encourage it further. The road had other plans though. Another dip and Cart arched her back slightly as this time the hardness pressed right up against her slit. "Stoppit," she muttered through clenched teeth in as soft a whisper as she could manage

Drake again felt himself grind against her and, though he didn't know exactly where his length had been shoved against, he wasn't a fool either. He had a very good idea, given her reaction. "You stop it," he countered, keeping his voice low enough that the radio almost completely drowned it out. There could be no further denying what was going on. He knew that she wasn't dumb, after all. Still, he wasn't about to outright tell her that she was making him hard either.

Nudging an elbow at her Bro, Cart tried to at least raise herself off his lap a little, hoping to alleviate the problem some. Another bump in the road ended that hope. "Mom! Are you taking us offroad or just aiming for every pot...." a series of bumps caused her to fall back to his lap, repeating an almost humping motion as her slit was practically ground against the hardness below her. The anger at her mother died out into a soft whimper that she had to bite her lip from vocalizing.

"What was that? I'm sorry you two, the road's really kind of iffy, we'll be to the interstate before too long.. hopefully."

Cart was starting to pant, her panties felt a little slick.

Drake, as things were, was having just as difficult a time as his little sister. That almost rhythmic grinding was starting to get to him and, despite his best efforts not to let it, instinct was winning out. He tried to stop himself, but he couldn't keep his hips from rolling back up against her. The young stallion was deliberately grinding his thick bulge against her panty-clad slit... and it felt pretty damn good at that.

"Stop," Cart whispered through gritted teeth... but even as she said it, she was reciprocating. After the discomfort of sharing a seat with her brother, the building warmth and rising shortness of breath was curving her actions. She ground back, worrying her bottom in his lap, even as she tried to ask him to stop.

Drake countered just as he had before, unable to stop himself from rubbing his aching length against her. "You stop," he told her. Despite the fact that there were a few layers of clothing separating the two of them, the sensation was heavenly. He was helpless to resist his actions, for it felt just too good to cease the rolling of his hips.

Groaning to herself, Cart shut up. She was having a hard time stopping herself. "Fine... just keep quiet," she said, almost like she was going to dictate this. She had no idea what she was doing, she just knew she couldn't stop, and continued to rub herself again him, starting a slow buildup climb. Her panties were becoming a sopping mess, and occasionally stuck to his shorts with each pass.

Drake wanted to stop, but he couldn't. To make matters even worse, he found himself doing things that he knew was crossing the line. His hand slipped under her dress and fell upon her bare thigh. He started to knead the firm, fuzzy flesh, alternately squeezing and rubbing her leg. Gods, this was so wrong! He knew that he was a pervert for enjoying it, yet his body wanted it so.

Cart should have taken his hand off her thigh, but she didn't. They had like 8 hours to go on this ride still and this was at least giving them something to do to take their mind off the discomfort of being squished together... never mind the fact they were actively trying to grind together now. Maybe she could help him get off and it would solve the problem?

When you're getting hot and bothered, non-sense answers seem to make more sense than they rightfully should. She slowly brought a hand down between her legs to repeat what he was doing to her leg, rubbing his leg and feeling up his thigh.

Drake's hand stroked up and down along her thigh. He gave it a squeeze and, with each pass, his fingers drew further and further up between her leg. Before even he realized it, he could feel his fingertips brushing along the edge of her panties, meeting that spot where leg connected to crotch. "C-can you turn the music up a little, Mom?" he questioned, worried that one of them might make a sound that would give away their actions. No longer did he want to stop. The stallion was giving in to instinct and giving in to desire. Little sister or not, he wanted the filly.

"Uh, sure," their mom said, turning the music up. She hummed a little with the tune, happy at least that they weren't at each other's necks.

Cart let her brother's hand roam, even as their wrists bumped slightly. She had to widen her legs a little to give herself access to her brother's thigh. She was losing herself just as much as he was, creeping her hand up his shorts, until she could feel the tenting fabric, giving it a gentle caress. Something in her mind told her this was wrong, that she should stop, but something else in her instincts pushed her on, telling her they wouldn't survive the trip if they didn't take care of this.

Drake's hand didn't stop there. It continued to explore, moving until his palm cupped her panty-clad cunny. "We shouldn't be doing this," he whispered to her, lips brushing against her ear as he spoke. Just the same, he didn't; couldn't stop. "But gods, I want you, Cart..." he continued. His palm ground against her mound and he hoped that she would release him. This just wasn't enough. He wanted more.

Cart didn't answer him, her tail flicked a bit against his stomach, signaling she wanted him almost as much, but she couldn't say it, let alone imagine it. Her hand started to move from caressing and teasing, to tugging at the fabric, pulling at it till she could actually feel the warm flesh of his hard member. She wrapped her hand around it and started trying to jerk him off, not committing anything of herself to him and hoping she could get him off easy. Her hips ground needily against him, angling his cock to rub against her panties, her mind not realizing how thin a barrier of protection they were.

Drake's fingertips teased her slit through the moist fabric, but even this wasn't enough for the colt. Moments later, he had tugged the crotch of her panties aside so that he could caress the hot, silky flesh of her bare slit. He understood just how dangerous of a game it was that they were playing. He realized that no brother should ever be this intimate with his sister... but gods help him, he wanted to be inside of her. He wanted to cram his hard, thick cock inside of her tight, little pussy. He wanted to stretch her until her cunny ached. He wanted to fuck her until she couldn't walk straight afterwards. Worst of all, he wanted to flood her hot cunny with his forbidden seed.

Cart tensed up as she felt her dripping panties pulled aside, and felt his bare fingers caress her, teasing her folds. Up until he'd moved her panties, she'd been dry rubbing his flared cockhead against them and it was slowly driving her wild. Primal instincts were screaming she needed to be filled, but she couldn't, not with her brother... not here in the car with their mother less than 5 feet away. She had to consciously aim him away from her dripping slit, trying to prevent contact, but every time the car jostled and bumped, her slick wetness kissed along the length of his shaft and once or twice he came close to hitting home. "We can't..." she moaned in a whisper.

Drake continued to stroke her moist, silky pussy lips, even as he responded to her words. "Did you want me to stop?" he questioned. "All that you have to do is tell me to, sister, and I'll stop touching you like that. Gods know that I don't want to, though. I know it's wrong, but I want to be inside of you, Cart. I want to feel that tight pussy of yours squeezing my cock."

Once more, even as she continued to say no, she didn't stop. Her own hand was guiding his cock, rubbing it across her lips, letting it slide past, giving it a coating of her juices. She had to bring a knuckle up to her mouth to moan into and try to keep her voice down. She didn't look like she was ready to stop, especially with one hand still stroking his cock.

Drake gasped and he felt the hairs on the back of his neck stand up as though her very touch was electric. He opened his mouth, about to say something, when fate intervened, making the decision for them. The car hit another pothole, sending the siblings bouncing in their seat. His sister dropped just as she was rubbing him against her lips, spearing her on nearly half of his thick, throbbing length before either of them knew what had happened. The stallion didn't know how he managed to suppress a moan, but somehow, miraculously, he remained quiet.

Cart froze a moment, realizing the jolting change. He was in her... she could feel it, it felt hot, and wonderful and everything she'd wanted. She tried to ease herself up, keep this from going too far.. but now that she had it, she didn't want to lose it. "Just... just the tip," she whispered, as if this would be okay. She started to tease herself down and up on just the tip, trying to keep herself raised.

Drake throbbed inside of her. It was far too late for just the tip. He knew he was already a few inches inside of her. The stallion could feel the tight, wet heat of her slit surrounding him and it felt wonderful. "I want more," he whispered directly into her ear. "Sit down, Cart. Let me all the way inside of you. If this only happens once, I want it to happen right."

At his urging, she wanted more too. She really wanted it. She let herself go in and out at the top once or twice more, but then she slowly let herself go a little further down, before coming up, and then a little further down again, whimpering into her knuckle as it just felt so damn good. It was like getting nibbles of a cake and she wanted a bite. Her brother was big, but it felt like she could take it, and she wanted to find out for sure. She pressed her back to his chest and slowly, she sank down, spreading her legs as wide as she could in the cramped space they had to let him fill her up. Sinking all the way down till his flared tip was nearly scraping her cervix. "You... you have to warn me, you have to pull out," she whispered, taking things a step further so quickly from her 'just the tip'. She hadn't really thought it through and had no idea where he'd 'let loose' in the car.

Drake gazed up front, making sure that their mother couldn't see them in the rear-view mirror, then tilted his head and kissed her neck. "Mhmm..." he agreed, having every intention of doing as she asked. Of course, he had no idea where he would be able to blow his wad in the confines of the car, but that was the furthest thing from his mind at the moment. All that mattered to him was the pleasure centered in his loins and the female in his lap. His arms circled around her, holding her close and holding her tight, and his hips slowly started to roll. His member rocked back and forth inside of her, moving less than an inch in either direction.

Cart kept the one knuckle in her mouth as something to suck on and keep herself quiet, while her other hand went from grabbing and squeezing her own breast to going down below her skirt and rubbing at her clit, and then to feeling her brother's balls, and how heavy they were. God it was hot, god it was wrong, god why couldn't she stop? She let him rock the two of them, moaning into her hand with every thrust from below, feeling how perfectly they fit, how much nature's design of a stallion's cock and a mare's cunny locked tight.

Drake gasped as she reached between her legs to feel his balls. It was likely unintentional, but it seemed almost as though she knew exactly how to drive him wild. She felt so damn good wrapped around him like that. The mare was tight, but not overly so, as though his shaft was stretching her just so slightly that brother and sister were a perfect fit for each other. "Damn, runt," he moaned, lips brushing lightly over her ear. "I can't believe we're doing this. It's so wrong... mmm... but it feels so good."

"I know.... it's so hot, but wrong," she said and gave his balls a final squeeze. She didn't want to play too much with the trigger on a loaded gun, and went back to teasing her clit. Her poor cunny was dripping and she wouldn't be able to last long with his wonderful cock filling her. She could already feel her orgasm rising up like a storm, and she knew she'd have to pull herself off, or there'd be no turning back. She'd clamp down and that would be it. Blindly, she took her hand off her clit and tried to hit the automatic window, she could smell herself. This much excitement and a stallion in her, it was almost like she was going into heat.

Drake's hips jerked up when he felt her gently squeeze his balls, driving himself deep enough inside of her that he could feel the head of his shaft strain her cervix. They were perverts. They were freaks. Still, he didn't care. He knew that, even after this encounter, he would want more. Already he was thinking about finding the nearest drug store after they got home and buying a fresh pack of condoms. There was no telling if his sister felt the same, but no other possibility occurred to him in his lust-driven state.

Cart started to rock her hips down to meet her brother's on each thrust. The heat inside her was building and she was getting close to edging. She didn't need to tease her clit anymore; she was already getting dangerously close. She put a hand on her brother's thigh, getting ready with leverage to pull herself off. "I'm getting really close bro..." she whispered and there was a whine to her voice that told him she really meant it.

Drake took her ear between his teeth and gave it a gentle nibble. The hand upon her thigh moved back between her legs. He felt at where he disappeared inside of her, then shifted his touch until he found her sensitive button. "Close?" he questioned as he brushed against her firm clit. "Are you going to cum, runt? Gonna cum for your big brother?" His words sounded strange to his ears, but speaking them sent a thrill through his spine. Hips continued to roll, his shaft still moving just barely in and out of her body.

Cart felt her back go stark rigid as he brushed her clit. Combined with the hot breath and nibble of her ear it sent her bursting over the edge as she bit down on her knuckle hard. She had meant to push herself up and off of him when it had happened, but the sudden surprise of it obliterated all rational thought in her brain. Her cunny clamped down like a vice on his cock, squeezing and working like a pump as he could FEEL that she was cumming, even if the sudden slight wet slurch of her fluids wasn't enough to tell him.

Drake took her ear between his teeth again, this time to keep himself from moaning as her already-tight wall rippled around his length, working to try to get him to cum. He tried to summon the willpower to pull out, but he hadn't the strength to. His cock throbbed and pulsed and his hips rammed upward as hard as he could in their awkward position. As he felt those hot juices drench his groin, he joined his sister in orgasmic bliss. Hot, thick jets of his incestuous spunk sprayed from his tip, splashing deep inside of her cunt. The male flooded his little sister's womb with his potent seed, his length twitching and jerking between her milking walls. They had sinned together, but the feeling of wrongness had yet to cross his mind. How could anything that felt that good be wrong?

Instinct beat sensibility. Convulsion beat rational movement. Cumming harder than she ever had in her life, and feeling the fiery warmth blossoming within her, Cart could only do what her body was programmed too. She thrust her hips down, riding out her explosive orgasm, her cunt milking his cock, drawing in every drop of his seed, as nature had designed her cunt to do. His flared tip was pressed right against her cervix, and with her mashing her ass down in his lap, it was practically forming a seal. Even with the copious amount of fertile seed, nothing was dripping beyond her own juices that slicked his balls and got the seat below him a little wet. Her mind was still in the process of rebooting as she struggled to understand what had happened beyond just having the best orgasm of her life.

Drake's member continued to throb between her milking walls even after he had given her every last drop that he had to give. The male panted with his teeth still on her ear and his hot breath teased her skin. Even a few minutes later, when his length started to soften within her, he still didn't quite comprehend what had happened. It was too foreign a concept to process and his mind was taking a long time to understand that which his body instinctively knew.

Cart could sense it too... her ear flicked in characteristic annoyance as her mind started to race. Had that just happened? Was her cunny filled with her brother's seed right now? How could he have? No, she knew she'd just been as much to blame, and she couldn't deny how good it felt. She pulled her ear from his mouth, and rather than comment about what had happened, she went into damage control. "When you soften enough, pull out and quickly pull my panties back into place or we're going to ruin the seat..." she whispered.

Drake's eyes shot wide open when he heard his sister's voice. Suddenly, he understood just what had happened. "Oh crap," he said. "Fuck, we messed up." The stallion's heart raced as a sudden flood of confused, mixed feelings assaulted him. What they had done was wrong. It was sick. Still, it was the best orgasm that he had had in his life. He loved his little sister and, to complicate matters even more so, he still wanted to do it with her again. "Okay... okay... panties," he said, keeping his voice low enough that only the two of them would hear. Fear caused him to soften even quicker and, with a clumsy, shaky hand, he pulled her panties back over before his seed could escape her pussy. He then attempted to stuff his messy length back into his boxers, desperately trying not to think about how his cum would soon be drenching the crotch of her panties, lest he grow hard all over again.

Despite the initial hope that the tension would ease off after 'release', Cart sat in awkward silence for another few minutes, her chest heaving, her back still pressed to her brother. Her mind was racing, and her body still tingled with after the affects. She didn't speak again until she suddenly felt sticky wetness coat her panties. "Mooom? Can you pull over? I really er... have to pee!"

"What? Pull over?" their mother asked, turning down the radio to hear her.

"Yah! I gotta pee, bad! All the bouncing," she said looking back at her brother with a blush.

Their mother grumbled a little bit at the explanation, "I'm just pulling off to the side, there's nowhere to stop before the interstate."

"Fine!" she said hopping out before the car had completely stopped rolling. She didn't even make much of an attempt at modesty. Although her mother couldn't see it from the opposite side of the car and the angle, Drake got a view of his sister heading toward the tree line and kicking a leg up to try and slide her panties down mid jog. Gathering her dress and holding it about her waist, Cart squatted and used her hand to splay open her pussy. She sat squatting a moment and it might have looked like she was going to relieve herself, but she didn't. As she squatted a fat white glob slowly left her, dripping to the ground. "Oh god..." she said as steadied herself. It hit her a little harder just what it meant.

Drake pretended to look away, though the act was more for his mother's sake than his sister's. Even so, he saw exactly what had happened. A big, white glob of his seed dripped out from between her legs to splash on the grass. The first was followed by a second, smaller one, that bubbled from between her lips and clung to them, refusing to fall on its own accord. Gods help him, though. He knew that he should be disgusted by what they had done, but it actually had quite the opposite effect. He felt his half-flaccid length twitch, halting its retreat.

Cart wiped her hand across her slit, frowning and then wiping it on the grass before standing and trying to pull her panties back on. They still had a bit of 'stickyness' to them, but at least she wouldn't be adding to it. She got back to the car and slowly slid into her brother's lap again. "Thanks mom, sorry for the unscheduled stop," she said sheepily. When the car was moving again, she quietly whispered "I soo have first dibs on the shower when we get there."

Drake blushed lightly beneath his fur when she settled back on his lap, knowing that she must have felt him starting to harden again. "Not if I get there first," he countered. Regardless of what they had done, they were still siblings. The shower would always be something that they fought over.

After a few moments had passed and they were well on their way, the young stallion spoke up. "So... Now what, Cart?" He questioned. "Is that something that we never talk about again? I mean... I know I'm probably sick for saying so... but it felt really, really good."

"It just happened, we talk later... if at all," she said. To her, this was something to tip toe around, and especially not discuss with their mother nearby. She made a nod toward her mother and repeated again, "Later."

If the ride had been awkward before, it was redefined now. They eventually made it to the interstate, and were on the road another four hours before they took the time to stop at a rest stop so they could stretch their legs. Cart was quick to leg it into the bathroom again, earning only a shake of her mother's head and something about a bladder the size of a peanut. Inside she was using some water to wash out her panties that had gotten a little crusty, and then nervously dry them with the hand dryer, snapping them behind her back whenever someone walked in and offering nervous polite waves. Eventually she got 'fresher' underwear on and went back to the car.

"There's not like a pharmacy near the state campgrounds, huh bro?" she asked. They would be gone for weeks, and she had more than a few things to worry about, but even given his obvious eagerness, she walked with a slight waddle and tingle that she'd be hard pressed not to pursue again.

Drake thought for a long moment, then shook his head and shrugged. "I dunno. Doubtful," he replied. "It's a bit out of the way. There might be a gas station or general store, but that's probably it." In the time that it took for her to clean up, his arousal had gone back down at least, leaving them one less thing to worry about. Still, he felt bad about it all.
