Sparky had been infatuated with Lucy since he’d first smelled her. His sensitive nose had picked up some unknowable but exciting aroma when Max had come to the pokemon lab. It had never been clear to Sparky what enticed him so about his partner’s younger sister, but she always smelled just a little musky, a kind of aftershock of something exciting. Whatever it was, it had captivated the young tepig. Upon arriving at Max and Lucy’s home for the first time, Sparky recalled being drawn to a room by that enchanting smell, only to find it in such concentrated amounts on that particular bed. He’d only gotten to explore the new senses for a moment, before Max had departed and Sparky had returned to his pokeball.

In the times since, Sparky found that Lucy continued to exude this alluring musk. But then, Max had given Sparky the chance to train with Lucy, and the young tepig had found the joys of battling. True, he’d only ever been in a few scrapes, but working with Lucy, and making friends with her slowly growing party, it had all been so wonderful. Then just earlier that day, as that startled blitzle had come charging out of the treeline, Sparky acted and Lucy followed. The two had been in sync and in just a blink Sparky was victorious while Lucy examined her newly filled pokeball.

Sparky had felt a kind of pressure welling up in his chest, a kind of pride at his accomplishments, accompanied by unbridled joy at having connected so strongly with Lucy. This feeling hadn’t left him, and then, as the sun began to set, Sparky had felt an explosion, a kind of release that left him warm and ecstatic. It wasn’t really clear in his memory, but when Sparky again looked up, he found himself looking at Lucy and Max, but his perspective was off. For a moment he couldn’t figure out what had happened, but even as he came to grips with the change he’d just experienced, Lucy flung herself around him.

Still reeling, Sparky could only focus on that comforting, intoxicating smell as Lucy cried out in excitement at his sudden evolution. After a moment Max approached and spoke with a glowing look of congratulations to his partner, before pointing out a particularly new facet of the pignite’s new body.

The rest of the evening had been a blur in slow motion. Sparky could hardly wait, though he didn’t fully know for what. It was clear that Max was going to teach him something, and that Lucy would be involved, but as the group retired to the tent for the night, Sparky was confronted by a sight he didn’t even know he’d been missing. Lucy had entered and immediately dropped her pants. The shirt followed shortly after, but with that first article removed, Sparky discovered, once and for all, the source of his beloved scent. That aroma he’d cherished now filled his mind as Lucy disrobed. Once more, Sparky was made aware of a tingling sensation in his nethers.

After she was asleep, Max had taken him aside and taught Sparky about his own body, bringing about new changes, though with less fluorescent results. Sparky could have almost forgotten about Lucy, as Max stroked and kissed his growing appendage, except that Speck had done his very best to flood the small tent through his devoted licking. Then the moment came, and Max, almost cruelly, sat up and brought Sparky to sit between Lucy’s inert legs.

Max had carefully spread her apart, allowing Sparky his first real glimpse of that which had captured him. The gentle movement of lips had caused small pulses, unconscious contractions at the new motion, or perhaps a kind of reaching gesture as though Lucy, even in sleep, were missing the ministrations of her loyal companion. Now, as Max gestured to a prominent opening, lower down, Sparky came to understand more fully what was about to happen. His penis was now vibrating, though this was more a result of Sparky’s excited, tense shaking. Max reached out and took hold of his partner’s dick and guided it down towards that beconning entrance. Despite his new comprehension, the moment seemed to drag out, as Sparky suddenly found himself at a precipice, about to cross over into something new. 

Then, almost imperceptibly, Sparky felt a new warmth. The precipice was no longer a ways off, Sparky had arrived, and without hesitation, he lept.

Max was blown away by the gusto with which Sparky took to his new activity. Sparky was off to the races. His hips thrust forcefully against Lucy, cock buried deep within her. It was unlike what he could remember of his own first time with Lucy, which had been more tentative and unsure, or Speck’s which had seemed almost mindless. Sparky was simply driven. Max had little doubt that this was the first time his partner had ever come close to anything like this, but now, watching the orange and black pig, Max knew that this was an almost inevitable outcome of Sparky’s infatuation.

Max continued to watch for a moment, before he was reminded of other, more pressing matters, by a snuffling at his wrist. Speck had leaned his head across Lucy’s stomach and was nuzzling Max, evidently intent of having a good time of his own if the glistening scarlet halfway emerging beneath the large dog was anything to go by.

Max, for his part, was all too happy to switch to something a little more hands on. Afterall, he’d acquainted himself with his partner and set the pignite to work. At this point, Max figured the next interesting part would be when the ‘mon came and given the robust motions, fixed pace, and look of intense concentration on Sparky’s face, it didn’t seem like that would be happening too soon. Besides, he had his own stiffy to worry about, and a new found ally ready to fix that problem. At least in exchange for Max’s help.

Making his way around to the expectant pooch, Max considered his options. The night before had been unplanned, but now with a better idea of what might follow, Max figured he might be able to organize things a bit differently.

Speck had hiked up his leg, presenting his half-exposed cock. The crimson shard stood out against the ‘mon’s dark gray belly. All told, Max was not too much larger than Speck, though a lot of the dog’s perceived bulk came from his long fur.

Max knelt next to Speck and pressed on the ‘mon’s side. “Come on boy, roll over,” Max encouraged. Without much coaxing, Speck readjusted, now looking for all the world like an excited pet waiting for a belly rub. Max was more than willing to oblige.

Kicking his leg up and over Speck’s chest, Max now straddled the shaggy mightyena. The large ‘mon didn’t put up any resistance to this position, so Max figured he couldn’t be causing too much discomfort. 

For a moment Max just took in the warm fur as it caressed his balls and tickled the base of his dick. The feeling was quite pleasant, more soft than bed sheets, but nowhere near what he was looking for, in terms of satisfaction. Sliding his rump back and bending down, Max came to a lying position, almost like he was on hands and knees across his sister’s partner. Again, he noticed the exquisite warmth and silkiness as he rubbed against Speck’s fur.

Max’s reverie was broken as he felt his cock suddenly enveloped in a warm, wet blanket. Glancing behind him, Max could see the outcome he’d been hoping for. From this position, his crotch was sitting just above Speck’s face, his penis dangling down for ease of access. Speck, for his part, was now eagerly tucking into his master’s cock, ready to receive a tasty treat.

Looking back down, Max was again reminded that Speck was ready for more than one kind of treat. The knotted cock was now almost entirely exposed and already depositing droplets along the mightyena’s stomach. Taking hold of the base with one hand, Max angled the enticing morsel up and dipped down to begin his own snack.

Like the night before, Max found himself savoring the strange bitter fluids. It wasn’t that it tasted so good, but that it was now part of his anticipation, the flavor reminding Max of his own pleasure. Unlike the first time, which had been tentative and exploratory, Max now found himself dipping his head with gusto, dragging his friend's length in and out of his mouth. The motion of his head caused Max to gently grind up and down Speck’s chest, rubbing along the soft fur, while Speck continued to lap along Max’s shaft. Max now clutched beneath Speck’s knot, keeping the slippery rod in its place. Speck had begun to push his hips up, in a short spastic rythm like before, but on his back Speck couldn’t put as much force behind his thrusts.

Along with the soft fur, Max’s mind was focussed on Speck’s licks along his cock and balls. From that angle, Speck could not apply as much pressure, but he made up for this with frequency. The mightyena's long tongue played across Max’s length, starting at the tip and dragging up across the young boy’s testicles, leaving a glistening coating of saliva.

With this cacophony of sensations, it did not take long for Max to cum. Without warning, Max began to hunch in ward, hips driving his dick down, into Speck’s waiting maw. Speck seemed unperturbed by the sudden intrusion, happy to be receiving the scrumptious gift from his master. The gratitude also came from what was happening lower down. As he bent, Max’s mouth had slid further down the dog’s length. Not to be bothered by any discomfort, Max was now nose-to-knot with his mightyena and his supporting hand was squeezing in just the right way. 

Still riding his own orgasm, Max suddenly became aware of an influx of fluid. Speck had also begun to cum and his tip, which was buried deep in the back of Max’s throat, was letting loose a torrent of cloudy liquid. Max was still preoccupied with his own sensations and simply swallowed the lot without complaint. Dimly, Max also made out Sparky’s squeals of delight. Max knew subconsciously this meant his pignite had likely come to his own crescendo, though he did not have the time, air, or clarity of thought to do more than acknowledge this fact.

The chaotic joy of the moment did not linger for long, however, as Max became quickly aware of his need to breathe. Before, he’d been able to make do with breathing fitfully through his nose, but now Max was faced with a significant impediment. Speck’s knot had expanded. Max generally found this to be a cool and appealing thing. While he’d been sucking Speck, Max was both admiring the bulge and appreciating the aroma’s the mightyena gave off. These were strongest when he got near the base and that lovely mound of flesh came closer, but now it wasn’t just closer, Speck’s knot had come right up against Max’s nose, blocking his nostrils off completely. From the side, this hadn’t been as much of an issue, but now Max was completely unable to take in air. In a moment of panic, Max wrenched himself back and off of Speck’s cock in a shower of cum and the sound of gasping. Speck, who’d finished with Max’s offering and had been basking in the boy’s attention was now cumming into thin air.

After a moment, Max caught his breath and, looking back down, realized that Speck was also finishing up, the ropes of cum now more like strings and threads, splattering against Max’s chest and dripping down onto Speck. Max was about to return to his friend's cock when he felt something quite new. Speck, having lost access to Max’s dick when the boy sat up, was now sniffing around Max’s butt. What had really caught Max’s attention, however, was the first long lick across his rear. Speck was now quite busy drawing his tongue across Max’s tailhole, seeming quite content to switch his attentions, now that the fun was wrapping up. Max, who’d never experienced anything like this, was taking to the new sensation. Speck’s tongue slid across his sensitive ring, tickling in a peculiar way. It wasn’t like when Speck lapped at his dick, but Max was quite pleased at the feeling.

The new experience didn’t last long though. Max and Speck were both roused by Sparky’s contented squeak. As Max looked over, he saw the little pig slump over and roll off of Lucy, a look of bliss plastered across the little pig’s face. Suddenly feeling his own exhaustion, Max hiked his leg back up and over Speck, giving the ‘mon a brief belly rub in thanks before standing up. Speck set about cleaning himself off as Max stepped around his sister to where his fiery partner lay.

Sparky had mostly retracted into his sheath by the time Max got there. The squat pignite was lying on his back breathing heavily, just his tip still exposed. Max could see that the little guy was splattered with fluids, though as he looked over to Lucy, he noticed that she wasn’t leaking the way she normally would after Speck used her. She was glistening, but otherwise there was nothing to indicate that Sparky had just been pounding her. Max shrugged, figuring that the pignite just didn’t cum very much, not really putting together than the small pig had been buried in his sister for at least as long as Speck had spent cumming in his mouth.

“Alright buddy, did you have fun?” Max asked his exhausted partner.

“Bui!” Sparky responded, simply.

Chuckling at the matter of fact response, Max grabbed the pignite’s pokeball and, with a red flash, put his partner away for the night. Feeling sleep overcoming him, Max returned to his sleeping bag, turning out the lamp on his way.

The next morning began as usual. Starting with their mother’s voice, Max and Lucy awoke. Unlike most mornings, however, Lucy did not dress before exiting the tent.

“Hey! Aren’t you going to get dressed,” Max called after her, confused by his sister’s change of pace.

When he got no response, Max quickly put on his clothes and followed her. He saw her a short ways from the cave entrance, squatting near some bushes. Then it dawned on Max what was going on. Now somewhat relieved, though still confused, Max turned to the task of getting food ready and packing to head out. As he was pulling supplies out to make breakfast, Max felt a tug on his arm and turned to find Lucy, looking perturbed.

“What’s up?” Max asked his sour-faced sister.

“I can’t pee,” Lucy responded matter-of-factly. 

Now this caught Max off guard. “What do you mean? I just saw you pee.” Max asked.

“Yeah, but it didn’t all come out. I still feel like I need to pee, but it won’t come out!” Lucy said, now with a bit more emotion.

Max was supremely confused at this point. “What do you mean, though? Like what does it feel like” he asked again, trying to get more clarity.

“I don’t know! I woke up and I really needed to go so I went and peed, but it still feels like my tummy is tight,” Lucy said.

Still at a loss, Max asked, “Does it hurt? Like are you really uncomfortable?”

Lucy shook her head, “No, it just won’t go away.”

“Well why don’t we have breakfast and see if you get to feeling any better while we’re out on the Route?” Max had no idea what to tell her, but if she wasn’t in pain, he supposed that it might clear up if she were up and about. “Why don’t I finish putting this together and you can go get our bags packed, that way we can start moving as soon as we’re finished?”

Lucy nodded, still looking a bit annoyed at whatever she was feeling, but moved off towards the tent. Max watched her butt, which stuck out from under her nightshirt, as Lucy ducked and disappeared inside the tent. Putting Lucy’s complaints aside for the moment, Max returned to the food and soon had a nice bit of oatmeal ready when Lucy reappeared.

“It still feels weird,” Lucy said as she sat down to eat.

“I’m sorry, let’s just try to get to town, and maybe we can figure something out once we reach the Pokemon Center?” Max still had no idea, but since she was up and about, he didn’t want to wait around in the cave to figure it out. 

“Alright,” Lucy responded. “I can walk fine, it’s just weird.”

With that, the two tucked into their meal and, before long were packed up and headed out.

Back on the open route, Lucy seemed to perk up. She was now able to distract herself with the sights, sounds, and smells of nature. The cave had been interesting enough, but without a pokemon to feary them across the water at the rear, Max and Lucy hadn’t really found much to do at Wellspring, at least while the sun had been up. Max was likewise finding himself enjoying the day, laughing as Lucy ran up and back, full of boundless energy.

The walk continued in this fashion until not long after the siblings turned at their previous rest stop to walk on towards Nacrene City. Lucy was just off the path, walking along a fallen log. Max watched as she came up to the end and jumped far and high off the end. The young girl came down in a bit of a heap, but nothing that Max hadn’t seen her do several times already. For Lucy, however, the landing was quite different. As she came down, legs bending beneath her into an awkward rolling finish, she felt something shift. It was subtle, like a little bit of warmth had moved somewhere inside her, but what came next was quite noticeable.

All at once, Lucy felt her panties grow wet as something flowed out of her. Her first response was confusion, she had just peed a little while ago, what was this? Then she remembered the tightness she’d woken up with. The niggling feeling had been with her all day, but as she’d been distracted, it had slipped her mind. Now, however, she was realizing that whatever it had been was coming out. Standing again, Lucy clasped her crotch with her hands, as though to hold back the flow of whatever it was.

Realizing it wasn’t stopping, Lucy did the only thing she could think of, she ditched her pack and dropped her pants, kicking them off as whatever was leaving her body flowed down along her legs. She heard Max call out as she disrobed there beside the path, but his concerns were not Lucy’s priority. Squatting down, Lucy watched between her legs as a milky liquid dropped in a long, thick string onto the leaves beneath her. It was unlike anything she’d ever seen come out of there. This wasn’t pee, and it wasn’t coming out of the hole she peed with. Lucy couldn’t tell what was happening, but as she watched the thicker liquid pool between her feet Lucy began to feel the pressure that had rested somewhere above her crotch start to lessen.

Max had been quite perturbed by Lucy’s sudden nudity, she hadn’t even moved away from the route and instead seemed to be peeing where she stood, albeit with more flaily of clothes than usual. He’d called out to her to go into the woods, but Lucy was clearly not paying attention. Grumbling a bit to himself, Max stepped over to see what was the matter. As he did, Max caught sight of what was dripping out of his sister. The white-grey liquid Max saw was very clearly not pee. Max felt his stomach drop as he realized that this was cum, and a lot of it.

As he looked on, stunned into passivity, he saw Lucy bear down, as though she were clenching. The motion was followed by a larger blob of semen exiting onto the ground with a resounding splat, at least it to Max’s ears. It took a few more moments and some grunts of exertion before Lucy seemed to have cleared out the last of it. As Max watched, his sister reached down and grabbed at her pussy, seeming now curious about what had just happened. Looking on, Max saw his little sister push a finger up into herself, stirring her hand around inside herself, as if to dislodge any extra that might still remain. Then, with a wet popping sound that Max had become rather familiar with, Lucy pulled out her cum-covered digit and brought it up to eye level. For a moment she looked at the goopy appendage, examining the way it pooled together and dripped off, and then she brought it up to her nose and sniffed.

Lucy gave a look of disgust as she caught the smell of cum, but as she did so Speck stepped up, ready to avail himself of a tasty snack. Reaching out his tongue, Speck, who now stood in front of Lucy’s half naked form, began to lick off her finger. The young girl giggled at the excited lapping of her partner, until Speck had cleaned the digit to his satisfaction. Now he turned his attention to the puddle that had accumulated beneath Lucy. Setting to with gusto, the mightyena began snuffling around, licking the cum-covered leaves as though they were some great dish.

“Ewww-haha Speck that’s gross!” Lucy chided, laughing at the ‘mon’s apparent excitement. At this, Max was again reminded of her awakeness and the public nature of this particular event. Shuffling over to where they’d been deposited, Max picked up Lucy’s pants before heading back over to his sister. He didn’t want Speck to get his nose somewhere it didn’t belong during the day, Max figured he would have enough questions to answer without Speck going to town on an awakened Lucy. 

“Here, put these back on, where right on the route you know!” Max said, pushing the shorts and panties towards his sister. Lucy was still watching Speck, seeming to be both grossed out and enthralled.

“What was that? That wasn’t pee,” Lucy said, taking her pants from Max and bending to slide them on. As she did so, she felt another small squirt of whatever it was leave her vagina and begin sliding down her thighs.

Ever since he’d come back to reality Max had been trying to figure out a way to answer that question without revealing far more than he was prepared to. “Um, I’m not sure. How are you feeling? Are you alright?”

“Yeah I feel a lot better now,” Lucy responded. “But what was that? I’ve never had that happen before.”

Still trying to avoid answering Max said, “Oh, um, I don’t know. Is that not something girls do?”

“Nope,” Lucy said, shaking her head. “That’s not pee, and it didn’t come out of my pee-hole, so I don’t know.” 

Max knew this would be her answer, but was hoping playing dumb could get him out of the situation. “Oh, well are you feeling better now? You were complaining about needing to pee earlier.” 

“Yeah I’m okay now. All of that was in me,” Lucy had finished putting on her pants by that point, though Max noticed that they were quite wet through at the crotch. “Maybe we should ask mom?” Lucy suggested.

This was the last thing Max wanted to do. Thinking quickly he said, “Um, but, uh, what if she says you have to go home? Like what if she freaks out and makes us stop?”

That did it, Lucy was too invested in this journey to risk delaying it. “No! No, I don’t want to do that. Um, but I want to know what that was, though.” Lucy said, now starting to look upset, both at the confusion of what had just happened, and at the possibility that she’d have to give up her trip.

Not wanting to drag this out, Max hit on a solution, “What if I called Melanie and asked her about it? She’s got Nicky and maybe she’d know something.” Max saw Lucy’s face brighten at this.

“Oh would you?!” Lucy squealed, emotions high at the possibility of an answer that didn’t truncate her quest. 

“Um, yeah, sure. I can call her later. Maybe when we get to the Pokemon Center. Don’t you want to battle the Nacrene Gym?” Max was trying to delay, he didn’t want to involve Melanie in this. Despite how she was clearly alright with him and Nicky having sex, Max didn’t want to have to explain all of this to her.

The ploy worked however, “Oh right, I almost forgot!” Lucy said, seeming to have already moved past the concerns of a moment before. Now, without that tightness in her stomach and with a clear goal, Lucy was ready to charge ahead. 

Relieved at the distraction, Max steered the conversation towards the impending battle. Lucy was all too happy to talk strategy and launched into her battle plans. Max wasn’t really listening, instead he turned to Speck, who’d finished with his meal and was now sniffing in Lucy’s direction. Max shook his head firmly and Speck, loyal as ever, seemed to understand. The ‘mon seemed to understand how this general relationship worked and, for the moment, was content with what he’d gotten out of the deal.

Lucy was once again ready to go, stepping out with gusto onto the path, ready to make good time. It wasn’t even noon and Max knew they’d be arriving soon. As they walked, Max thought about what had just happened. Lucy had been stuffed, but from what? Max could only assume that all that was Sparky’s doing, though he wasn’t sure just yet where the squat pignite had put it all. Max realized that he still didn’t have as much of an idea about what he was doing than he’d thought. He was having fun and learning, but there were still aspects that he didn’t fully understand. For now Max knew that he couldn’t have Sparky going at it with Lucy, at least until he knew something more about what pignite did while mating.

As Max and Lucy came up to Nacrene City, Max could see an old set of railroad tracks, just a bit further down from where he and Lucy now stood. Further along there were some buildings and the signature red roof of the Pokemon Center. With an excited whoop, Lucy took off down the route and, with less energy, but no less excitement, Max followed. There were complications to sort out, but for now Max was going to watch his sister clean house in another gym. Questions could be answered later.
