The Stars in Her Eyes: Of Nuts and Nerds

By Green

The door slid smoothly open with a soft, almost inaudible whoosh, allowed entrance to two people, and then just as smoothly and just as quietly slid closed again, fitting so flush with the wall that the seam was barely visible in the smooth, reflective surface. The whole room was very sterile, almost lifeless, or at least it would be if one entire wall was not taken up with a transparent window which currently showed the planet Earth and its Moon, floating serenely in the infinite void. The taller of the two occupants, a troubled-looking human, walked up and put one hand on the window, as if trying to feel closer to the planet.

"So much has changed since I was frozen..." he whispered, "I barely recognize my own world anymore." The other occupant, a shapely golden retriever with long blonde hair, stepped forward and put one hand supportively on his shoulder.

"Not everything has changed, Marcus," she whispered, with the tiniest smirk.

Turning away from the cradle of his species, the human regarded her with the sort of look that suggested he already knew where she was going with this, and fully approved.

"Oh yeah?" he asked, starting to grin himself, "Like what?" Stepping in closer, the canine gave him a warm smile and bedroom eyes, reaching up to rub the man's solid bicep through his outfit as her other hand reached up and began unzipping her shirt.

"Maybe it's better if I just show you..." she teased, and she churred to him as she eased her shirt open, revealing that she hadn't been wearing a bra underneath it. There was a bed just across the room, but at the moment, the dog just leaned back against the desk just beside them as the two space explorers began to chart the new territory of each other's bodies using their hands and lips...

"Oh, you've gotta be fucking kidding me," Stuart groaned, shifting in his seat uncomfortably as the golden woman got her heavy, full breasts out. The capybara knew he shouldn't, but he couldn't help but admire them.

"Jesus, they might not have fast food anymore, but they definitely still have real tits in the future..." he murmured, shuddering indecently. To his chagrin/delight, the camera lingered on the happy couple far longer than he expected, even got a full shot of the human naked from behind as they made their way to the bed, before some non-explicit shots of what he had to assume was only simulated intercourse. Very convincingly simulated intercourse.

"Goddammit, why is that every show I stream suddenly has to have sex scenes in it?" He was sitting in his gaming chair in front of his desk, and he'd been quite comfortable trying a new sci-fi series, right up until the point when things got naked and sexy. It wasn't that he was disgusted, or a prude, or anything, far from it, Stuart Rodriguez was comfortably straight and ordinarily one very horny capybara. In fact, at that very moment, he realized he was idly rubbing his penis through his shorts. Yelping, the embarrassed male yanked his hand away as if his twitching dong had become red hot.

"I never should have taken that fucking bet..." he groaned, and not for the first time.

It had been Halloween, and as was his tradition, Stuart had been spending it watching awful, awful horror movies from the 70s and 80s with his younger sister, Stephanie. The two of them had always had a very strong bond that they hadn't shared with their other siblings, and they spent a lot of time together. It had started with Stephanie pointing out that the next day was November 1st, of course.

"I'm sure you've heard of it online, they call it No-Nut November, and you just try not to come for thirty straight days!" Her words echoed in his mind. This particular challenge, between these particular rodents, would probably seem extremely inappropriate to most people, but there were extenuating circumstances here.

"What's the matter, big brother? Don't think you can outlast me?" He'd known he shouldn't take the bait, shouldn't take the bet, since he was pretty sure girls were better at keeping their urges under control than guys, giving Steph an unfair advantage, but when she started pushing his buttons, he just couldn't turn down her challenges. Capybaras had a strong reputation as a remarkably calm, zen sort of species, but there had always been a friendly competitive spirit between Stuart and Stephanie.

So, naturally, he'd said yes, and now it was week two, and Stuart was practically dying from the need for release, getting worked up from idle sexy thoughts, let alone a TV show suddenly going softcore at the drop of a hat. Indeed, just sitting here, in the loosest shorts he owned, Stuart was at half-mast even though he'd stopped rubbing himself. He told himself that at the very least, he would force himself to protect his dignity, to pause the show and go jack off to some real porn instead of touching himself to a sci-fi drama that happened to have tits in it. Then, naturally, he pushed that thought out of his mind as well, finding it way too tempting a backup option. But he couldn't give up now! After all, if he lost, Steph would - WHAM! Stuart jumped slightly in his chair, startled, as his door suddenly flew wide open, boldly kicked by Stephanie herself, who strolled into the room like she owned the place and put her hands on her hips, watching her brother with a playful, yet teasing grin on her face. Stuart, though, was distracted from her expression by the fact that she was wearing a tight T-shirt, a pair of panties, some socks, and, judging by the divots of her nipples against the taut fabric of her top, nothing else at all.

Stephanie regarded her older brother with a supreme confidence that Stuart found ominous, even as it sent a pleasant shiver down his spine.

"Heya, Solo!" she announced, as if she hadn't just exploded into his room like a slightly more restrained Kool-Aid Man, "I was gonna ask how it's going, but I see that you're doing very well today." Following her gaze to the tent he'd pitched in his shorts, Stuart blushed and covered the bulge with both hands as she walked closer.

"Wh-what do you want, Steph?" he asked, distrustfully.

"Well, it's about this bet we made," she said, examining her fingernails idly.

"You're not trying to back out of it, are you?" he asked, doing an excellent job of sounding wary, and not like he was silently praying for her answer to be 'yes'.

"Oh no, nothing of the sort," the shorter capybara assured him, "It's just that when I agreed, I kind of figured I'd just wait a couple days and then you'd cave, and then I'd be the winner and I could tease you about it for the rest of the month." She glanced at the screen and smirked, and Stuart realized that as she walked in, he'd paused it on that love scene.

"A bold choice, under the circumstances," she teased, observationally, but said no more on the subject. Stuart's blush darkened immediately, and he silently thanked his lucky stars that at least no one's boobs or ass were on camera at the moment.

"I - I was caught by surprise," he insisted defensively, "I was just about to shut it off!"

"I'm just busting your chops," Steph replied, with a giggle, "Relaaaaax, Solo." The nickname came from way back; a big part of why Stuart and Steph were so close was that as children, they'd been equally obsessed with Star Wars, and a young Stephanie had once declared that her big brother was as cool as hotshot smuggler Han Solo. Stuart still maintained it was the best compliment he'd ever received. Curiously, Star Wars also had a lot to do with how their relationship had taken a turn and become far, far more intimate than most brothers and sisters. These days, the two Rodriguezes considered themselves 'siblings with benefits'. Which was, incidentally, the reason that the two of them were so comfortable making orgasm-related bets with each other. It had all started one cold winter night, when they had the house to themselves and they were watching Return of the Jedi for the twenty thousandth time, and - Stuart tensed up, forced out of his reverie by the slightly stubby finger poking him in the shoulder.

"Hey, are you listening?" Steph asked, dubiously, "Earth to Solo, come in Solo..."

"E-Earth can't call Solo, he's in a galaxy far, far away," Stuart grumbled. The truth was that at the moment, Stuart was having trouble even looking at his beloved sister, because her T-shirt (marked with the crest of the Rebel Alliance and bearing the slogan 'A Woman's Place is in the Rebellion') and panties (bearing a repeating pattern of Stormtrooper helmets) were so tight that any time his gaze drifted from Steph's eyes, he felt that damnable arousal start growing again.

Seeing his obvious frustration, Stephanie squatted down so she was eye-to-eye with her seated sibling.

"It's like this, big brother," she said, "Like I said, I figured it would only take a couple of days, you being an enormous hornball and all, but here we are, day ten, and you still haven't cracked!" She patted him on the arm playfully.

"Good job, by the way. It's just... the problem is that I kind of expected to win by now, and I... I'm finding it harder than I thought not to touch myself," she admitted, "God, I'm so fucking horny all the time... I - I can't believe I'm telling you this, but I keep soaking through my panties, it's getting embarrassing!" Stuart swallowed a groan of desire and felt his cock give a strong twitch. Before he could stop himself, he glanced down her body to look at her panties. They were mostly white, surely it would show easily... But he didn't see anything with that brief glimpse, and he looked away as she giggled again.

"How do you know I haven't just been playing you this entire time, and I've been jacking off whenever I felt like it?" he asked, grumpily, "You haven't exactly had me under video surveillance..."

"Silly Solo," the playful female said, "I'd know you lost because you'd come out to breakfast without being all fucking pissy the whole time." Despite himself, Stuart snorted in amusement at that, conceding the point. Steph leaned in closer, and her brother inhaled sharply as her soft breasts pressed against the side of his arm. Pretending she didn't notice the contact between them, Steph smiled warmly at him.

"So I decided that since we've got this whole apartment to ourselves, and all the privacy we could ask for, the simplest solution is to take matters into my own hands," she said, her eyes gleaming excitedly, "I didn't come here to welsh on the bet, Solo, I came here to win the bet." And with that, before Stuart had time to gather his thoughts, much less say anything, Stephanie reached out and grabbed her brother's penis through his shorts.

In retrospect, Stuart would wish he'd been centred enough to say something flirty or suave, or at the very least to suggest that she let go, but in the moment, he just moaned softly.

"Oh, fuck..." he sighed, shuddering as she gave his sensitive flesh a squeeze.

"I have you now..." Steph teased, which made Stuart flinch. Not only had she gotten the drop on him, she'd managed to work in a Vader quote, too!

"Y-you can't do that," the older rodent protested weakly, doing nothing to try and remove her hand from his cock as she massaged and kneaded his long-neglected dick, "We had a deal on how this bet was gonna g-go, and it didn't say anything about having to fend off your attempts to make me fail!" Without letting go of him, Steph gently shoved his chair away from his desk, then walked on her knees out in front of him, where she began properly stroking his shaft through his shorts. Then, to add insult to injury, she winked at him and delivered the coup de grace.

"I am altering the deal," she quoted, "Pray I don't alter it any further." Letting his head flop back onto his headrest for a moment, Stuart let out a groan that had nothing to do with his penis.

"Oh, you bitch..." he sighed, "Twice in as many minutes..." Stephanie giggled in triumph, then reached up and began tugging Stuart's shorts down. Anxiously grabbing hold of the waistband, the conflicted male tried to stop her from undressing him, but his heart wasn't in it, and she knew it. They'd always been able to read each other like the proverbial book, and right now, Stephanie would know exactly how much of an advantage she had.

Stuart whimpered as she succeeded in pulling his shorts away, but only because the voice of reason was still shouting over his arousal, screaming that he was going to lose the bet. But God, he needed to come so bad he could barely think straight... As soon as Stephanie closed her naked hand around her brother's tool, it throbbed hard in her grip, and a droplet emerged from the tip.

"Wow, I've barely done anything, and you're so hard already... but at the same time, you're pre-ing before you're even all the way hard!" Steph marvelled, "Jeez, you really do need it that bad, huh Solo?" Leaning in closer, she pressed her nose to the underside of his penis and inhaled deeply of his masculine scent, then planted a kiss on the side of his crown. Despite himself, Stuart groaned again.

"Awww, que pobrecito..." Stephanie whispered, and despite the condescending tone, her brother shivered again. He'd always had a weakness for when his sister dipped into Spanish, even if they'd never really leaned into their father's heritage.

Stephanie s-l-o-w-l-y stroked her hand up and down Stuart's rigid shaft, coaxing twitches and trembles and oh, so much pre-come out of it.

"This isn't fair..." Stuart mumbled, still unable to bring himself to resist. Her hand was just so soft and so gentle, and it had been so long...

"Look at yourself," Steph said, softly, "You want it so fuckin' bad that you're just letting yourself get casually dominated by your own little sister." She squeezed him on those last two words, and he moaned as he uttered her name.

"S-Steeeeeph..." She smiled up at him as he realized he'd already hit Maximum Blush, even if he was still capable of feeling further embarrassed.

"See? I bet you're enjoying it more because it's me," she teased, pausing to give one of his testicles a curious lick before adding, "Pervert." With her free hand, she was rubbing up and down his thigh, scritching her fingertips through his coarse fur. A capybara's hands are small and dark, with stubby fingers, but that just had the effect of making Stuart's dick look bigger in her grip.

As Stuart watched, Steph leaned down and dragged her tongue from the base of his prick all the way up the shaft to the tip, where she licked off the latest droplet of pre that emerged.

"How about it, Solo? Just relax and let me make you feel so much better..." she cooed, "Even if you lose the bet, at least you'll be able to come..."

"C-can I lose the bet inside you?" Stuart replied, defiantly, which got him a dirty look. The two rodents had done an awful lot together, but they'd never gone all the way into full penetrative sex... not yet anyway. Steph had never admitted it, but Stuart strongly suspected that it was because Steph told herself that as long as they didn't have vaginal sex, what they were doing wasn't 'that bad', even if they were siblings.

"Wise-ass," was all she said now, "Alright, time to make a choice, big brother: tell me 'no', tell me to stop, right now, or I'll suck your dick and make you come."

Stuart swallowed, shuddering. He'd never heard that used as a threat before... Stephanie reached out with exaggerated slowness and took hold of his cock again, curling her fingers around him almost theatrically before lifting him away from his belly and leaning in, parting her lips as her mouth grew closer and closer to the crown of his tool. And all the while, Stuart nervously stammered like an idiot.

"I - I - I - I..." Finally, the elder capybara let out a sigh of defeat and rubbed the top of his muzzle about where the bridge of a human's nose would be.

"I have a bad feeling about this..." he finally said. Stephanie giggled with both victory and purest delight.

"And he still works the reference in, not bad," she chuckled, as she leaned in to take her prize in her mouth.

This was where Stuart surprised his sister, by putting his feet flat on the floor and suddenly shoving the chair backwards, pulling himself away from Stephanie, who was left kneeling there with her mouth wide open in surprise. Looking up at Stuart with a nervous expression that suggested she thought she'd crossed a line, Steph smiled nervously.

"Uh..." she started, but before she could say anything coherent, Stuart stood up, bent down, and grabbed hold of Steph with both hands. The shorter capybara squeaked in shock as she was bodily lifted from the floor. Stuart wasn't exactly a muscular powerhouse, but Stephanie didn't weigh a whole lot, so it wasn't too much trouble for her brother to carry the stunned female over to his bed, where he unceremoniously dropped her. Then, as she watched him (or more precisely, watched his hard-on as it bobbed about in front of him as he walked), Stuart walked over to the door and closed and locked it. As he turned around he was already talking.

"I know, I know, this is our place, it's just a psychological thing."

Stuart walked back over to his bed, enjoying the way Stephanie was staring so openly at his penis, practically licking her lips as pre drooled down his shaft and dripped to the floor. He'd had a hunch, but seeing this, he was pretty sure she wanted to suck his dick almost as badly as he wanted her to do it. Realizing he'd been watching her leer at him, Steph blushed.

"I-it's just a waste, is all," she muttered, "All that cock, and you're not even putting it to good use..." Stuart chuckled at that even as he shuddered, and he climbed onto the bed, lying down on his back next to her.

"I know I shouldn't, but every word you say makes me want this more," he sighed, "Jesus, it's like you're the Rembrandt of turning me on." Churring softly at the compliment, the eager female moved over to kneel next to him and bent down, matter-of-factly taking her brother's dick into her mouth.

Stuart immediately groaned and shuddered at the feeling of Stephanie's soft tongue licking at his sensitive flesh, her warm, moist cheeks enveloping his tip. For a moment she lingered there, just licking and suckling on his crown, as if sampling his pre, before she began to slide down his shaft, careful not to make contact with the long, narrow teeth so common in rodents. Inch after inch disappeared into her muzzle as Stuart squirmed and moaned, and as she began to squeeze and knead his balls, Steph began to bob her head up and down her brother's prick.

"Oh - oh goddamn, th-that's so good, Stephie..." he murmured, as he placed one hand on her lower leg, which was just next to him, helpfully. Stephanie, who seemed quite pleased with herself, paid that hand no mind as it slowly creeped up her leg and onto her butt. Fairly typical for a capybara, she was short and a little bit pear-shaped, but this just meant that she had a terrific ass, and so she seemed unsurprised that her brother would want to touch and rub it while she fellated him. The younger rodent did seem surprised, though, once Stuart's fingertips wiggled their way under the elastic waistband of her underwear. Steph could only let out a muffled gasp as her brother's hand slid down into her panties and cupped a naked buttock.

Stephanie froze in place, as if she wasn't sure whether to keep going or not, but when Stuart began to tease the tip of one finger back and forth past her anus, she let his length slip out of her mouth and turned to glare at him. Her eyes narrowed still further when Stuart's response was to snort in amusement.

"Oh, what, you think I'm just gonna lie here and let you make me lose the bet, without trying to make you lose instead?" he asked, both eyebrows raising in false incredulity, "Come on, give me more credit than that, little sister!" She sighed heavily and pouted.

"Well, I - I - yes, I did think you were just gonna lie there and let me have my way with you!" she said, "I - I'm not really thinking straight recently, okay?" Stuart laughed delightedly at her honesty, but she looked like she was still going to complain, at least until Stuart's hand slid down a little further. Stephanie suddenly closed her eyes and moaned softly as her lover cupped his hand over her heated vulva, giving her slit a playful squeeze.

"Whoa, you really are wet," he observed, running his fingertips over her sensitive flesh, "Jesus, sis, I've never seen you this soaked! Why didn't you say something?"

"B-because I didn't want to lose..." she admitted, averting her eyes and studying her brother's pubic fur with interest far too focused to be genuine.

With the hand already buried in her undies, Stuart pushed two fingers between his sister's labia and into the warmth beyond. Stephanie whimpered with pleasure, her slick, hot pussy clenching down on the intruding digits so tightly that for just a moment, Stuart wasn't actually sure he could get them back. With his free hand, Stuart reached over and touched Stephanie's hip, then began gently but insistently pulling her rump off to the side... moving the lower half of her body so that it was suspended directly over Stuart. Steph swallowed, immediately seeing where this was going.

"Oh, S-Solo..." she whispered, before blushing and tensing up as her previous expression of determination returned. Stuart found himself wondering if it was just a mask, and wishing his sweet sibling would let her feelings show more often.

"Alright," Steph said, sighing as if allowing this to become a sixty-nine was a major chore for her, "But you know you can't win, right? I mean, you're a guy, I'm not, and I started already!" He spoiled the stern look in her eyes by making her gasp again, caressing her clitoris with the side of his thumb, not at all surprised to find the extra-sensitive nub fully emerged from its hood already.

With a grumble that Stuart estimated was 80% for show, Steph turned away from him again and returned her attention to his rigid dick, which had been patiently awaiting her, and hadn't gotten even the tiniest bit softer during their little exchange. Stuart swore under his breath approvingly as he felt the wet heat of his sister's muzzle enveloping his cock again, but focused on the butt above him. Slipping his fingers out of her (and feeling her pussy clench down in protest at this abandonment), Stuart reached up and pulled her underwear down over the soft globes of her ass, exposing her treasures to his eyes. He had to lift one leg, then the other, to carefully work Steph's panties down. He did pause, though, to glance at the tag.

"'Type H?'" he read aloud, "They still call these human-type panties? Damn specists..." The label merely referred to the fact that these panties had a solid fabric back, with no window for a tail. Unlike the majority of rodents, capybaras had no tails to speak of, just round, furry butts. Steph only grunted in response, clearly more interested in slurping along her brother's shaft.

It turned out that being directly underneath a girl was not a very good position for getting her panties off, and it was so very hard to focus on such a task with Steph's glistening pussy staring him in the face, so once he'd gotten one foot free, Stuart abandoned the sodden garment, leaving it hanging from her other ankle. Turning his attention back to his sister's cleft, Stuart raised both hands and firmly gripped a buttock in each. Then, he gently pulled Stephanie's rump down until he could press his lips against her slick labia, giving her southern lips a kiss before he gave her slit a long, wide lick. Both Rodriguezes sighed with pleasure as Stuart got to savour one of his favourite tastes, and Stephanie finally got some attention on her poor, neglected pussy. Knowing he was behind, and able to see exactly how ready she was, Stuart didn't waste any time before he resumed licking at her outer lips and her throbbing love button, making the younger capybara squirm and shudder above him, her stubby toes twitching down by her brother's shoulders.

Unable to wait even one second longer, Stuart slipped his tongue between Steph's folds, pushing it as deep into her welcoming body as he could. Sighing contentedly at the familiarly forbidden flavour of his little sister's nectar, he began to lick and slurp at her inner walls, swallowing her flavourful juices in greedy gulps. As he began to feast, Stuart moved one hand down below her pelvis so he could fondle and stroke her clit while he ate her out. Stephanie whimpered and shuddered as Stuart explored her tight channel with his tongue, rubbing and massaging along her walls and searching for extra-sensitive spots he could use against her. He needed to be on his A-game if he was going to catch up, after all...

As if she'd been reading his mind, Stephanie began moving a little faster, eagerly bobbing up and down his cock as she played with his balls. Stuart swallowed a moan, and focused on his sister's pussy, territory he knew a lot better than a brother probably should. He knew, for example, that even though Stephanie had physically popped her cherry with a dildo years ago (he'd been there, holding her free hand), she'd never actually known anyone biblically, and she still considered herself to have her V-tags... which Stuart wanted, so badly he could almost taste it. He couldn't explain why, exactly, he coveted his sister's virginity so dearly, only that he felt a profound longing to hold Stephanie in his arms, kiss her deeply, and make her his. Though he'd never told her about these urges he felt for things other than just helping her get off, he'd hinted on more than one occasion how willing he was to go all the way. So far, though, Steph had always rebuffed him, insisting that their 'benefits' were all about stress relief, and that bumping that up to casual sex would make things more complicated. He had to admit asking her to have her first time with her own brother was a hard sell when they'd never even kissed...

The eager female brought her lover's wandering mind back to the present by squealing with pleasure and clenching down on his tongue as he stroked her clit. With his free hand, Stuart had been squeezing and kneading the soft flesh of one of his sister's buttocks, and now he let it slide down a little, leaning back so he could slip his thumb into her pussy in place of his tongue. As he wiggled it around, getting it nice and wet with Steph's juices, Stuart smirked. Somehow, she never saw this one coming... Once he was satisfied with how slick his thumb had become, Stuart pulled it back out, moved in to continue licking before she had time to complain, and returned his hand to the other rodent's buttock. Then, he slowly moved it riiiight up to the top, his fingers resting about where the base of her tail would be if it existed, and he began to rub Stephanie's juices into the tight pucker of her anus. She released his cock to look back at him, so Stuart chose that moment to suddenly push, using a little muscle to overpower the stubborn ring of muscle and push his well-lubricated thumb into his little sister's ass.

Steph tensed up from head to toe, throwing her head towards the ceiling as she let out a powerful squeak.

"S-Solo!" she gasped, trembling visibly, but he caught her stopping herself from turning back to look at him, clearly embarrassed. Instead of saying anything, Stuart happily continued licking her pussy, and he began to slowly, gently slide his thumb back and forth, properly fingering her asshole. Steph shuddered and tensed up again, before a moan burst out of her like she'd been trying to contain it but failed. Unable to resist, Stuart leaned away from her slit long enough to tease her.

"And you pretend you're not into this," he chided her, playfully. This time she did meet his gaze, pouting at him with a distinctly self-conscious glint to her eyes. He expected some grumpy, yet halfhearted denial, but instead Steph remained silent, murbling sub-vocally with discontent. Stuart suspected that the only reason she wasn't blushing was that she'd suddenly become very flushed with arousal since her brother began to play with her. It was almost like she'd already been extremely horny just from going down on her own sibling, but that was crazy talk, surely...

Stuart smirked, knowing she'd definitely be breaking her silence if he'd said that out loud, and took a moment away from teasing Stephanie's clitoris to give her rump a tender pat. Sighing exaggeratedly, her nose wiggling with agitation, the younger rodent turned away again and returned her attention to her big brother's erection. Stuart shivered with pleasure as he felt Steph sniffing around the base of his prick, where the scent of his arousal was strongest, before beginning to lick at him again, this time without taking him into her mouth, bathing his taut flesh with long, gentle strokes of her tongue. Reminded by another pulse of pleasure that he had a job of his own, Stuart churred contentedly and leaned back in to resume licking at his sister's hot, responsive pussy, this time while also pushing his thumb in and out of her ass with slow, even thrusts.

The two needy capybara siblings focused on licking and pleasuring each other, the room falling quiet aside from salaciously wet noises and the occasional sigh or whimper of pleasure. Stephanie began to slowly stroke Stuart's tool with her hand while she took his balls into her mouth, one at a time, and suckled on them oh-so-gently. As he shuddered, Stuart turned his face to the side, feeling it would be rude to moan directly into Steph's pussy. He felt his cock throb hard, his tip up against something soft and fuzzy, and imagined his pre leaking into the fur on his sister's breasts as she focused her attention on his testicles. That particular pulse of pleasure had been powerful, and as the squirming male swallowed a moan, he began to fear that he wouldn't be able to hold the ecstasy off for long enough.

Leaning back just long enough to moan "Oh God, S-Steph...", Stuart changed his tactics, switching things up by bringing his lips to her clitoris, which he began to tease with the tip of his tongue, to Stephanie's obvious delight. Without missing a beat, he began fingering her rump with the thumb of one hand, and her pussy with the first two fingers of the other hand. She immediately clenched down on his digits, and Stuart shuddered with approval at the feeling of his sister's honey running down his knuckles. As he continued playing with her, the elder capybara realized that Steph was beginning to roll her hips, pushing back against the stimulation, and he felt encouraged that his fight had not been lost before it began. For her part, the horny female shuddered hard and swore under her breath before taking Stuart's hard dick back into her mouth with a quiet moan. Distantly, Stuart marvelled at how eager Stephanie always seemed when she gave him oral, how attentive to his sensitive spots and his turn-ons she was. How could she possibly be so good? He wished he had more experience to compare it to, but only one other girl had given him head, and that hadn't even been in the same league as when his sister did it. A thought which, in turn, made him consider the idea that this was so amazing because Steph was his beloved little sister, and not in spite of it.

Pushing that thought out of his mind, as it made him feel oddly anxious, Stuart focused on providing the very best cunnilingus to Steph that he possibly could. He felt so alive, between the sensations of Stephanie's soft lips and nimble tongue pleasing his cock, the warmth of his lover perched atop him, and the feeling of his sister's juices soaking into his facial fur as he enthusiastically worked the most sensitive parts of the younger rodent's body. Her toes and feet began to twitch and spasm as he licked at her clit and teased her inner walls, and he could swear she was getting even wetter than before. Leaning away from Stuart's prick, Stephanie moaned shamelessly, pushing her dripping slit back against her brother's fingers and tongue.

"Oh, f-fuck, that's s-so good... H-how are you getting me this c-close?!" she groaned, "Goddammit, S-Solo, this w-wasn't supposed to be f-fair!" In response, Stuart chuckled.

"Never t-tell me the odds," he quoted, to her annoyance and amusement. Before Steph could reply, he closed his lips around her love button and sucked on it the way he liked to suckle her nipples. On that note, he suddenly realized she was no longer wearing the Rebellion T-shirt with the female-positive message, and that her bare breasts were pressing against his stomach. His movements slowed for just a moment, as he wondered when, exactly, he'd been so engrossed in eating his sibling out that he'd missed her stopping to peel her top off.

At that moment, Stephanie took him into her mouth all the way to the balls, then sucked her cheeks in tight so that every part of her brother's dick felt the silky embrace of her muzzle at once. He couldn't help throwing his head back and moaning with need.

"Oh - oh my God, s-sis, that feels f-fuckin' amazing..." Stuart panted, feeling the pleasure starting to build up within him. Putting Steph's magical vanishing shirt out of his mind, he leaned back in and redoubled his efforts, working her sensitive entrances a little faster, a little more enthusiastically than before, and being more direct, with less teasing. He licked and slurped for all he was worth, drinking down his sister's nectar with the motivation (if not the desperation) of a man dying of thirst. At the moment, with Stephanie sucking his dick every bit as enthusiastically, and with her pussy staring him right in the face, Stuart couldn't help but imagine that she was rotated 180 degrees, that he was balls-deep in her tight, gripping snatch, that he was kissing her deeply and hungrily, showing her the fire hidden within him that burned so hotly for her...

Stuart blinked. What had that last one been, again? He'd been caught off-guard by the strength of that fantasy, and also by realizing for the first time exactly how much he wanted to make out with his little sister. The elder capybara self-consciously and deliberately focused his attention back on the task at hand, suddenly uneasy about the idea of dwelling on those thoughts for any period of time. He switched things up again, going back to exploring Steph's pussy with his tongue and fondling her clit with his fingers. Her butt, he continued to tease in exactly the same way, as he seemed to be doing a good job of it. Stuart whimpered quietly, feeling the point of no return hurtling towards him; after denying himself for two straight weeks, he needed to come, so desperately it was shocking, but he was still fighting it as hard as he could, desperate to hold out just... a little... longer...

The siblings licked and slurped and suckled and worked each other's sensitive, aching parts with their nimble, talented fingers. By now, Stuart could feel his legs twitching and dancing involuntarily just like Stephanie's, though perhaps not quite as powerfully; at one point, she gasped wordlessly, and her foot flicked up off the mattress, finally flinging her panties free so that they flew up in the air and landed on Stuart's shoulder. The trembling male barely even noticed the damp garment, so laser-focused was he on his sister's erogenous zones.

'Oh... oh God, no... It's too much... It's too good... I'm going to come!' Stuart thought, despairingly, which meant that Steph was going to win the bet, which in turn meant that... that... The thought suddenly evaporated into pure energy as the orgasm that had been building inside Stuart finally overpowered him, grabbing him with both hands and pulling him off the edge of the metaphorical cliff.

Tensing up from the tips of his ears to the bottom of his toes, and despite his intentions earlier, Stuart moaned directly against Steph's vulva, closing his eyes and surrendering to the ecstasy that was suddenly exploding within him. But at that exact moment, Stephanie let out a powerful moan of her own around Stuart's cock, their muffled cries practically synchronized. Pretty much unable to contemplate that with all the fireworks going off in his mind, the larger rodent just hung on and kept licking as his dick began to throb and pulse, spurting hot, creamy capybara jism into his little sister's welcoming muzzle. He trembled and shook as he painted Steph's tongue and cheeks with his seed, seeing stars even with his eyes closed. But even in the throes of a powerful orgasm, Stuart couldn't help but notice that Steph suddenly tensed up herself, grinding her wet slit against his mouth as she shuddered and shook, her vagina clenching down on her big brother's tongue almost as hard as her butt was clenching down on his thumb. As Stephanie's inner walls rippled along Stuart's tongue, she let out a muffled squeal, and a potent gush of her feminine juices suddenly flooded into his mouth. Even as he greedily swallowed, he felt it dripping out the corners of his muzzle and getting his fur even more soaked in his sister's passion than it already had been.

After denying himself for so long, Stuart felt like his climax would never end, like he'd just keep trembling beneath his sibling, ejaculating for the rest of time. Even as pleasure burned through him, he kept licking at Steph's spasming walls, rubbing her clit, trying to drag out what he was pretty sure was an orgasm of her own. Similarly, even as she swallowed her brother's seed, Stephanie was still stroking his throbbing shaft with her free hand, and using the other to continue massaging and squeezing his heavy balls like she was trying to drain every last drop of sperm from them. But end it did, eventually, when it felt like she'd milked him dry, and as it did, his body went totally, completely limp, his head and arms flopping back against the bed, droplets of sweat and juice flicking into the air as he let out a gasp that tapered off into a soft groan. For her part, Stephanie waited until she was sure he was finished, swallowed the last of Stuart's semen, and leaned back, letting his softening cock slip out of her mouth before she allowed herself to flop to the side and join her brother in lying there, panting wordlessly.

For a time, the Rodriguez siblings just lay there, staring at the stucco ceiling of Stuart's room and breathing heavily. Stuart hadn't felt that sated since - well, since Halloween night, actually, when the two of them had gone a little overboard in anticipation of denying themselves. He wasn't doing much thinking at the moment, just enjoying the feelings of contentment and satisfaction he was currently floating in. Eventually, Stephanie stirred first, dragging herself around so that she was once again aligned the same way as her brother, then rolling closer and resting her head on his shoulder. She sighed exaggeratedly.

"I can't believe we came at the same time..." Steph muttered, "Now we both lost..." Stuart chuckled tiredly. It was just like Steph to focus on that part. Turning his head to the side, he found her with her eyes closed, a serene expression on her face as she used his shoulder for a pillow. Her fur and hair were wild and unkempt from sweat, and it seemed like her entire body was flushed from exertion and how aroused she'd gotten, but in that moment, she was the most beautiful woman Stuart had ever laid eyes on, sister or no sister.

Reaching over, Stuart delicately touched his fingers to the underside of the younger capybara's chin. Stephanie stirred, opening her eyes, and Stuart found himself distantly wondering if they'd always been such a vibrant blue. He'd intended to say something charming, like 'Don't look at it that way, sis, maybe we both won', but when he met her gaze in that moment, something happened.

"Steph..." he whispered, lightly stroking under her chin with the side of his finger. Then, he rolled towards her, onto his side, and she lifted her head from his shoulder to let him do it. Stephanie just lay there, watching him intently as he leaned in closer, acting entirely on impulse, and brought his lips to meet hers. Then and there, lying on the bed in only their pelts, brother and sister kissed for the first time. Both rodents sighed contentedly through their nostrils as their lips met, pressing together... and parting. Stuart shuddered as he cautiously extended his tongue and met Stephanie's, already on its way into his mouth. As they began kissing the way siblings aren't supposed to, Stuart raised his arms and placed them on Steph's upper arms, just holding her for a moment, before reaching behind her and turning it into a full hug. Holding her in his arms, her warmth against him, felt almost as good as the kiss, but somehow, just for a second, even that paled in comparison to the joy Stuart felt when his sister began to hug him back.

The kiss was long and slow, their tongues coiling and entwining as they expressed emotions they'd never put into words. Stuart moved his hand up to run his fingers through Steph's hair, and he felt her shiver in his arms. Making this specific kiss even more perverse than the fact that they were siblings, was the fact that the taste of his seed on her tongue was mingling with the taste of her juices on his tongue. Stuart chose to believe this was creating an entirely unique flavour, a combination of their vital fluids that embodied the essence of the sibling pair and their taboo fun.

When they finally broke it off, they were so focused on each other's eyes that neither of them noticed the string of saliva and... other things... that connected their lower lips for a few seconds. Stuart just smiled, saying nothing. Stephanie smiled back, blushing slightly, but then she averted her gaze, steadfastly studying one of his shoulders instead. Stuart would have called it 'shy' if they hadn't just done a sixty-nine.

"...You shouldn't have done that, Solo," she whispered, with absolutely no emotion readable from her tone, "We're siblings with benefits, not a couple." Stuart swallowed, taking a moment to concentrate on suppressing the alarmingly potent disappointment he suddenly felt before he responded to that.

"...You say that, Princess, but you kissed me back," he pointed out. Steph pouted, her eyes briefly flicking back to Stuart's before she forced them back onto the nice, safe neutral ground of his shoulder. The way she was staring at it, Stuart was almost amused by the thought that she just wanted to use his shoulder as a pillow again, but the strange, contradictory emotions he was feeling were kind of drowning out the humour.

Sniffing haughtily, Steph frowned ever-so-slightly.

"Okay, number one, don't call me that, I'm not eight years old anymore. And number two..." she hesitated for a moment, her eyes once again flitting over to her brother's and retreating, before she took a deep breath and visibly relaxed.

"Well, even if I did kiss you back, you weren't supposed to do it in the first place," she insisted, clearly determined to make this his fault and not hers, "We had a deal." Reaching up to boop Stephanie on the nose, and smiling at the cute way she scrunched up her face in response, Stuart winked at his sister.

"I am altering the deal," he said, and Stephanie laughed, then groaned, seemingly trying to drown out the inevitable follow-up, "Pray I don't alter it any further."

The two capybaras laughed together at that, enjoying the absurdity of the moment, and the warmth of being cuddled up against another person. When they calmed down a little, Steph's smile faltered slightly.

"Really, Solo, that was dangerous, kissing me like that," she murmured, putting a hand on his shoulder to show she wasn't mad. "We came up with those rules to make sure we keep things casual, keep our hearts out of it, and so we don't blur the lines between siblings-with-benefits and... well, anything else." Her cheeks had turned ever so slightly pink. Stuart swallowed again, wondering if these instinctive reactions of disappointment were something he should worry about. So instead, naturally, he focused on something else.

"Alright, number one," he said, deliberately mimicking his lover, "How come you get to call me Solo if I can't call you Princess anymore?" The younger rodent smirked and gave him a Look at the same time, no easy feat.

"Because Princess is a nickname normally used by six year old girls who still believe in fairies," she said, bluntly, "Solo, on the other hand..."

Stuart couldn't help but chuckle. He just felt really good after such a powerful orgasm, like he was wrapped in a warm blanket of afterglow. It helped to be holding his beautiful, witty, naked little sister against himself, of course...

"Okay, fair," he acknowledged. He hadn't actually had a second thing to say, but as that thought about how nice it was to hold her led to a memory of how amazingly soft her lips had felt against his, something occurred to him.

"...And number two, since I got you to break the rules with me... I guess that means I win." For a moment, Steph's brow furrowed, as if the shapely capybara didn't even understand the words he'd just said. Then, as the sentence clicked into place, the surprised female's eyes widened until they resembled the proverbial dinner plates.

"Wait, what do you mean you win?!" she asked, pushing herself up on one arm so she was looking down at him. Stuart watched her with amusement, regarding her with a calm smile.

"Well, we came at the same time, sis," he said, "We both lost No-Nut November simultaneously, so the bet ended in a tie. And since I just successfully tempted you into breaking the rules with me, I'd say that's as good a tiebreaker as any!"

Stephanie looked at him in sheer disbelief for a moment, then she shook her head and laughed.

"Alright, fine, you win," she said, making a vague gesture of surrender, "I guess you got me." She lay back down, and Stuart immediately pulled her into his arms again. She returned his embrace and sighed contentedly.

"Mmmm, this feels nice, big brother," she murmured, nuzzling against his cheek, "But we probably shouldn't spend too much time cuddling afterwards..." She made no move to extricate herself from her brother's arms.

"Why not?" Stuart immediately replied, "None of the rules say siblings-with-benefits can't cuddle."

"True," Steph admitted, "But... being in all close like this, naked... it kind of makes me want to kiss you again." The taller rodent wanted to cackle in triumph, but managed to keep it restrained to a polite chuckle. Meeting Steph's eyes, Stuart gave her a wide, warm smile.

"...It was a nice kiss, wasn't it?" he whispered. Despite herself, Steph smiled back.

"You know what?" she replied, "...Yeah, yeah it was."

With that, she moved to stand, and Stuart reluctantly released his grip and let her get up, staying right where he was on his bed and watching as Stephanie scooped up her shirt and panties from where they'd been discarded. He quite enjoyed the view as she bent over to grab the garments, something he was sure she was aware of. Rather than putting these clothes on, she simply carried them, naked, over to Stuart's door.

"That was amazing, I really needed that, but I'm gonna go take a shower, get freshened up," she said, unlocking and opening the door without looking back.

"Hey," the sated male called. Steph stopped in the doorway and turned to meet his gaze again. Grinning at her, Stuart sat up.

"So, does this mean... that I get Netflix control?" Making a face, Stephanie sighed exaggeratedly and nodded.

"Yes, Solo, it means you get control of the Netflix watchlist for the next month," she replied, play-sullenly. Stuart laughed delightedly and raised a fist in the air. For Stuart and Steph, part of the fun of their sexy little bets was that none of the stakes were ever high enough to cause either of them any actual stress.

"You know, sometimes I amaze myself," Stuart quoted, doing his best Harrison Ford. Stephanie rolled her eyes, but couldn't completely hide her smile.

"Alright, I'm off, thanks for the stress relief, big brother," Stephanie said, nodding to him. As often happened at the end of their trysts, Stuart found himself compelled to look her over one more time, just in case he never saw her naked again. As he took in Steph's soft, heavy breasts, her shapely rump, and the way her pelt glistened in the light with sweat and juices, Stuart smiled. Once again, he liked what he saw.

"Any time, little sister, any time," he replied. She turned away, and he watched her tailless tush as she slipped out of his room. He closed his eyes and fondly remembered the view of her pussy just before he'd leaned up to begin licking... and the way she'd shuddered in his arms as he'd kissed her.

"I love you, Stephanie," he called, smiling widely as he lay back on his bed and sighed comfortably.

"Love you too, Solo," she called back, and Stuart chuckled to himself. The nerdy capybara dearly enjoyed these forbidden games he played with his sister, and he was already looking forward to the next time they made a wager. Not to get too sentimental or anything, but even if she was his sister, Stephanie might just be the most amazing woman he'd ever had in his life. The joy she took from the hobbies they shared was almost as delightful to Stuart as the hobbies themselves, and he'd felt so contented, so much happier, since they started fooling around together. Steph may have been reluctant about going any further with their taboo fun, but Stuart sensed that she was curious about it, maybe even wanted it the way he did. He wasn't sure how the future would go, and it was possible he was reading this entirely wrong, and trying to push things with his sister could be disastrous, but in his heart, Stuart felt... a new hope.
