An Eevee finally finds the Thunder Stone that will allow him to evolve. One thing stands between him and his dreams, a desperate Pikachu.



Thunderous Consequences

Pokémon: Eevee x Pikachu.


The Eevee peered down the dark chasm. He was shaking all over and took a moment to steel himself. Once he was calmed, he looked once again down the fissure.

Yeah, he could definitely see it. It was hard to spot at first. A faint glimmer shrouded within the shadows. Oh what he would give to have the eyesight of a Sableye right now. Eevee looked around the inner chamber of Luxo Cave once again, just to make sure no other Pokémon had snuck in. The shiny crystalline surfaces of the cave around him reflected and refracted the light, resulting in an almost dazzling display of brightness. This just made the absolute darkness of the chasm below even more daunting, but Eevee tried to push that fear to the back of his mind and focus on his goal instead.

That glimmer. It would be an easy mistake to dismiss this shiny object down in the darkness as yet another crystal reflecting the light from above. But that, Eevee knew, wasn't just some worthless diamond-- it was a Thunder Stone. His friend had spotted it earlier that day and was nice enough to tell Eevee that he had found the treasure Eevee so desperately sought. He owed Growlithe one when he next saw him. Eevee had been so excited about the news he left without even saying thanks. That was rude of him. Now he was here, deep in the dangerous depths of Luxo Cave. All by himself.

Eevee considered the rocky descent in front of him. A tap with a front paw gave him good news. The rocks were not as slick as they appeared and he'd at least have a little grip. The gradient was steep but manageable. "Alright, here I go," Eevee said, trying to remain calm. He turned around and looked up at the shiny ceiling. He felt for the edge with his back paws, and then slowly tried to find a foothold. Step by step he descended the rocky wall. This would be so easy if he could learn Rock Climb. But no, he was just an useless Eevee. Well, not for long-- or so he hoped.

Before he knew it he was out the bath of light and surrounded in darkness. It was scary for sure but he had to be brave. "Come'on Eevee," he said to himself quietly, "Scaredy Pokémon don't get to evolve." It felt like forever as he clambered down into the depths. He had no way of seeing what was below him and had to rely on feel alone. The muscles in his short legs began to ache with the effort and sharp jags of rocks were scraping along his underbelly.

At last, he probed for the next foothold underneath him and found his foot colliding with the cold ground. He yipped in surprise and happiness and at once clumsily dismounted from the rocky face. For a moment he lay there on his back, exhausted but content. He stared upwards at the hypnotic spirals of coloured light welling around the ceiling of the chamber.

Eventually, Eevee rolled onto his side and then stood back on his feet. His legs still ached, but success was invigorating. Looking around the chasm, he quickly located the shiny stone that he'd went through all this trouble for. He took it in both paws and held the perfect jewel up to the light. It was, in fact, a Thunder Stone; one of the rare elemental items that would allow him to evolve. Never having seen one before, Eevee found himself awestruck for a moment. Just being near it made him feel energised, and somehow he felt ready for the climb back up the cliff.

Holding the Thunder Stone in his mouth, the Eevee gave one last sweep around the bottom of the chasm. In one shadowy corner, he spotted a crack in the wall. "Looks like Luxo Cave goes deeper still," he thought, before quickly drawing his attention away from it. He's got what he came for-- that can be an adventure for some other Pokémon.

The ascent seemed much easier than the descent had been. Maybe it was just his new positive frame of mind, but even including the stone he was awkwardly carrying in his mouth, it wasn't much trouble. The second he felt the edge of the floor above him he grabbed onto it with both paws and pulled himself up, rolling onto his side and then his back, laughing as he did so.

At that moment he found a blinking face looking down at him. Her eyes widened as she joined in with his happiness.

"A Thunder Stone!" She squealed. Eevee looked at her cautiously as he scrambled to his feet. She was a Pikachu. Her yellow furry form was smaller than his own, and the curved tail marked her as a female. Eevee dropped the Thunder Stone from his mouth and instead clutched it protectively in his front paws.

"Hello," he said coldly. "Who are you?"

"Oh, yeah, sorry. You must be surprised to see me. I'm Pikachu! I've been looking for a Thunder Stone for soooooo long. Like, three weeks! Maybe four. I was told to come look here and this place was all shiny and then--" The Pikachu spoke so rapidly that Eevee could hardly keep up. Eventually, she cut herself off and got to the point. "I searched for, like, forty minutes when I finally found my way back here and found it! Man am I glad to see you!"

"I'm sorry," Eevee said, politely. "I went through a lot of trouble to get this Thunder Stone. I need it. It's mine."

The Pikachu's ears drooped as she looked down at the Eevee's clutching paws.

"I'll-- I will buy it off you!" she said passionately. "I've got this mean stash of berries, like Chesto Berries, Lum Berries, one or two Pinap Berries-- "

"No I'm sorry," Eevee interjected. This girl was incredulous but he wasn't about to go and lose his temper. "This Thunder Stone is not for sale."

Tears welled up in the Pikachu's eyes and she turned her head to the side. Eevee saw her tail twitch and the sadness was replaced with anger on her face. "No! No I need it! Give it here! I demand you!" She approached, about as threateningly as a Pikachu could be. Eevee stood his ground but shrank inwardly.

"Please calm down," he squeaked. He was generally caught off guard when the Iron Tail came zipping through the dry air and whacked against Eevee's furry collar. The force of the impact through Eevee up into the air and he came down hard onto his back. He groaned in frustration and pain, and then his eyes widened.

Eevee watched in paralyzed shock as the Thunder Stone rolled gently to the fissure's edge, froze on the brink for a moment, before tumbling over the side and into the abyss from whence it came.

Having overcome the fit of anger, Pikachu gulped in guilt. "Fuck," she said, stepping back a few paces. "I'm-- I'm so sorry!" Eevee stood back up and stared at her, taking a steady step forward. "Please-- look, I was just so sick of being a Pikachu." Eevee tilted the front of his head forward and the world went dim around him. He saw the enemy in front of him but did not hear her words. "I just wanted to evolve so badly! I shouldn't have done that, that was terr-- "

The Take Down from the charging Eevee was powerful enough to send the smaller Pokémon flying. Eevee followed up before his victim had even hit the ground, firing an array of star-shaped projectiles that homed in on his target, allowing him to be lazy with his aim.

Pikachu recovered quickly but did not fight back. It's possible that a well-placed Thunderbolt could save her, but she was simply too terrified to think. "Please don't! I'm so sorry! I'll make this right, I'll go get it!"

She sidestepped just at the last second and the Eevee went barreling into the wall of the cave, hit hard by the recoil of his own Take Down.

The fight froze as they heard what sounded like glass shattering in slow motion. Within seconds they both ducked for cover as shards of crystalline earth rained down from above. The cracks spread across the surface of the ancient walls, and soon heavy chunks of crystal and stone were hailing downwards.

Amongst the dust, the adrenaline-filled Eevee saw the terrified Pikachu, curled up on the ground and attempting to use her tail to shield her body from the carnage around her. Despite everything, the Eevee found himself throwing his own body over her's so that he sustained the bulk of the damage.

It was over as quickly as it started, and soon the two Pokémon were left alone in dusty silence.

Eevee dismounted the crying ball of fluff and looked around the chamber. The cave-in had sealed the only entrance behind a semi-transparent wedge of crystallized carbon. Over the ensuing minutes, Eevee made some attempts to force the boulder out of the way, but all he succeeded in doing was confirming one thing. They were well and truly trapped here.


Eevee hadn't remained conscious for much longer, a combination of exhaustion and injury left him sleeping. He was eventually roused when Pikachu began screaming for help at the top of her lungs.

"No one is going to hear you," Eevee stated. "We're at least a mile underground. Few Pokémon have any reason to come to Luxo Cave." The Pikachu was all cut up, but even from a distance Eevee could tell that her wounds weren't too bad.

"Are we going to die here?"

"No." Eevee climbed to his feet and came over to her. "Is anyone going to come looking for you?" he asked. Pikachu was silent for a moment, and then shook her head. Eevee felt a little sad. "Well, my friend Growlithe knows that I'm here, he will bring any Pokémon who can help and come looking for me. Don't worry, we just need to wait it out."

"Okay," Pikachu said in a nervous whisper. She finally relaxed and sat down with her back against the cave wall. "Sit with me, please," she asked. Eevee did. "I'm so sorry for provoking you, and losing the stone, and thank you so much for protecting me. I was rude and impatient and-- "

"Don't worry about it." Eevee gave per a reassuring pat. "I'm sorry for losing my temper too."

Silence resumed once more as the two Pokémon sat side by side. Eevee reflected that this is probably the closest he's been to a girl, and how cute the Pikachu was. For the first time since meeting her, his mind wasn't clouded with suspicion or anger. The sincerity of how she spoke, and the excitable passion she exhibited earlier. It was really hot.

"Do you hate me?"

"No."

"How are you so nice?"

Eevee laughed kindly. "Oh, I'm not. You saw me attack in cold-blooded anger. We both caused this mess, I can't hate you any more than I hate myself. Now come on, stop worrying about it. We should sleep."

Eevee resumed his nap, but this time snuggled at the side of a warm and fluffy Pikachu.


"Should I go down and get it?" Pikachu asked, leaning over the edge of the fissure.

"Nah, trust me-- we're both too weak for that. Let's just forget about that dumb stone for now." Neither of them knew how long they had been in the cave for, but now they were almost as hungry as they were bored. Pikachu swore that it must have been at least twelve hours, but Eevee insists that it has been closer to five.

"Hey so, why did you want the Thunder Stone so bad?" She asked.

"I wanna get stronger," Eevee replied, simply. Pikachu wasn't taking that as an answer and bugged him until she got a better response.

"Well I love to battle, but I keep losing to all my friends," Eevee said. "Normal Type isn't cutting it, so I wanted to evolve."

"I guess that's fair enough," Pikachu said. She was surprised that the matter was so straightforward, considering the ferocity with which he avenged the fallen Thunder Stone. "Well considering how you battled earlier, I would say you're already very strong."

"Hey, thanks!" Eevee felt proud that he could hold his own, although in this instance the aggressor hadn't fought back. "But as a Jolteon, I'll be stronger!"

"I guess that's true."

"So why do you wanna evolve?"

The Pikachu blushed and laughed. "Well err... can I be honest?"

"Please do." Eevee didn't want to pry, but she seemed happy to open up.

"Well, so," she paused but then quickly resumed, a couple of notches down from her normally exhausting tempo. "Please mind the crudeness. I really wanted a mate. I was looking for one, like, all summer. I'm sure you've noticed but I can be pretty annoying and impulsive and-- " she paused and glanced away from him, "and nobody wants to be around me for any longer than they have to."

She stopped for a moment, and Eevee was about to interject to reassure her, but then she continued, and he was afraid to interrupt. "Then I met this Manectric, and he said he would be my mate, but if only I was a little bit bigger..."

She stopped again, and this time Eevee was pretty sure she was done speaking. "Wait, so, " he began, as he put two and two together. "You wanted that Thunder Stone so desperately... because you were horny," Eevee stated.

Pikachu laughed at his directness. "Yes, yes! You've never had to go through heat! I would've done anything, anything to stop that from happening again. And... I just wanted someone to like me so badly..."

"I like you," Eevee said, before even realizing he had done so. She glared at him in disbelief. Eevee gulped and continued, being honest had gotten him this far. "No, seriously. I'm not just saying that. You shouldn't evolve for somebody else, you should evolve for you! You terrified me at first. You just appeared and came after the one thing I thought I needed. But, I like you. You're nice and honest, and you can be a little hard to follow, but you're passionate and you're cute-- "

"You think I'm cute?" she asked.

"Yes," Eevee said. His voice didn't falter. She looked at him in genuine surprise. He wasn't a bold Pokémon, but he felt bold now. "And I would like to date you. I would like that very much."

Eevee didn't know what response he expected, but he jumped with shock when she squealed in delight. "Yes!"

The two Pokémon snuggled together. They both knew they were going pretty quickly, but now they felt less trapped.


"Are you sure Growlithe is coming?" Pikachu asked. She was certain it had been at least a day by now. Neither of them could take much more of this. They were enjoying each other's company, but there was just nothing for them to do in this crystal chamber.

"Yes, he'll come," Eevee replied. He sounded pretty sure of himself. "We just need to find some way to pass the time."

"Like what?" Eevee asked, punctuated with a bored moan.

"We could play a game."

"Orrr we could do something else..."

Eevee was about to ask what she meant, but one look at her face told her everything. "Oh... you want to mate?"

Pikachu blushed and cringed at the word. "Oh, well, yeah. Maybe. I'm sorry that was very forward, I don't wanna make you feel uncomfortable or anything. We probably shouldn't mate out of boredom..."

"Why not?" Eevee asked. Pikachu's eyes lit up at the response, so he continued. "I would like to mate with you."

"It would be my first time," whispered Pikachu.

"Mine too," Eevee replied, in a low, gentle voice. Eevee was getting riled up just from the thought of it, but the last thing he wanted to do was pressure a girl who was physically trapped with him into sex. "Let's only do this if you absolutely want to though. There's no rush, if we stick together once we get outta this pl--"

"No, I want to!"

Well, that was that. "Okay. Let's do this. How should we begin?"

Pikachu gripped a rock with her front paws. She ducked her head, so that the curve of her back was parallel with the cave's floor. She lifted her thunderbolt tail up into the air, showing off to the bewildered Pokémon behind her.

"Oh my." Eevee took a few steps towards her, peering at the beautiful sight between her legs.

Pikachu laughed and swiveled her head to look at him over her shoulder. "Did you just say 'Oh my'," Pikachu teased. She suddenly felt the weight of the Eevee on her back as he mounted her. Pikachu gasped as she felt the canine shaft poke at her entrance.

"Tell me if you want me to stop, okay?" Eevee said. He was eager, happy to lose his virginity to such a lovely Pokémon. Pikachu was eager too. She ducked her head and squeezed her eyes shut as she felt the shaft push between her vaginal lips. At first, just the tip was inside of her. It was so warm Pikachu could've sworn that Eevee was secretly a Flareon all along and she found herself grinding backwards against the meaty shaft.

"We gotta take this slowly," Eevee said. He was trying to keep his cool, despite the fact he was currently experiencing the greatest feeling of his life. He had an adorable, eager girl waiting for him to plunge his dick into her. He was always so busy with his training, he didn't think he would ever find a mate. He must be the luckiest Pokémon alive! "I'm a little bigger than you. I don't want to hurt you."

"Don't worry, I can take it! I'm tougher than I look," Pikachu said, confidently. "Please." That gave Eevee the courage he needed to finally take the plunge. He felt tiny electrical shocks as he pushed through her folds-- but they only served to heighten the experience. Eevee began to pull out and swelled with pride upon hearing the moans of the Pokémon below him. "Don't stop Eevee. This is so good," she said.

The innermost chamber of Luxo Cave was filled with the sound and scent of the two mates. The walls of the cave seemed timeless, still and immovable. The light that the cave was famous for swelled and spiralled across the surface of the crystals, and at its center the two Pokémon fucked. Pikachu was very wet and that made sex easy. A few thrusts in Eevee realized that his concerns were unfounded and finally committed to letting loose. the Pokémon happily humped his willing mate, growing in speed and confidence with every passing second.

"Yesssss," Pikachu hissed. "Ugh this is so good! You're so fucking good!" Eevee grabbed Pikachu's tail with his mouth and held it in a gentle yet firm grip. He found himself putting all his force behind his pounds like he was competing in an intense battle. It was clear nothing short of a full-force attack could bring any harm to his lover. The feeling was amazing. It was the same adrenaline he got from battling, but combined with a divine pleasure, and the happiness that came with pleasing his mate. But like all good things, it had to come to an end, and Eevee was dimly aware that he was fucking at an unsustainable tempo. He felt the welling inside him, the churning inside his sack, further stimulated by the electric pulses riding through his body.

"Pikachu! I can't hold out any longer!" Eevee said. Even when he was angry, his voice had remained calm and level. Right now it was anything but, as he gave one last almighty thrust into his new lover. Pikachu was dumbfounded as a lifetime of desperation was satisfying all at once. Fuck the Thunder Stone, this was a billion times better. This is what she needed. Pikachu came. She had made herself cum many times in the past, by desperately humping or rubbing herself up against something or another. This was nothing like that. Where as then her orgasm sated her heat but left her wanting more, this time it pleased her on a much deeper level.

Eevee finally bottomed out, and shot deep into the Pikachu pussy. As he came down from his high he felt the knot at the base of his dick swell, binding them together. He had completely forgotten about that pesky bulb, but that's alright. He wanted nothing more than to be together with her right now. "How was it?" Eevee asked between pants.

Pikachu didn't answer for a moment. She heard the words, but it took some time for her mind to process them. "A- maz- ing," she said. "So much better than I hoped." She could feel the knot inside her, trapping his canine dick. It was gonna be a few moments until he could dismount. They lay there in the light of the cave and basked in the afterglow.

"Hey so," Pikachu started. "How much longer do you think it is gonna take your friend to find us? Can we go again?"


Eevee tried not to let his concern show on his face. They had mated two more times, and now he was cuddling up with Pikachu against the far wall. She was giddy, so happy even given the fact they were still imprisoned here. Growlithe should've found them by now. Eevee had no idea what was taking his friend so long.

Pikachu spoke a ponderous stammer, snapping him out of his own paranoid thoughts. "Hey so, if we hadn't fought and got trapped here, do you think we would've kept hating each other?"

Eevee thought for a moment before replying. "Yeah, almost definitely. You came after my Thunder Stone I really didn't like you. I would've had no reason to stick around with you after leaving this cave."

Sadness and regret welled up inside Pikachu, feeling ashamed of the first impression she left. She did appreciate the bluntness of his answer, though. "I'm sorry for trying to take your st--"

Eevee laughed and shook his head. "You've already apologized, I'm over it. And hey, we met in the worst of circumstances. We both desperately wanted the same rare treasure, it was inevitable that there would be conflict. I saw the worst side of you, and if getting trapped in a cave is what it took to see the best, then I'm happy I did." Pikachu was almost in tears at the sentiment. He continued. "I love you. I'm glad I came here, I'm glad I met you. Hell, I'm glad you knocked the Thunder Stone back into the ravine. Huh, maybe I should go retrieve it now..." Eevee climbed to his feet. "Yeah, I'll go back down there and get it, then we can decide what we want to do with it. Sound alright?"

"Yeah sure. I don't want it anymore, I found what I really wanted. How long are you gonna take?"

"Not too long. Maybe 15 minutes. There's nothing down there except the Thunder Stone and that cra-- " Eevee froze and his eyes widened. "Oh shit."

Pikachu looked up at him, alarmed. "What's wrong?"

"I'm an idiot. After meeting you I forgot all about it, but when I was at the bottom of the ravine, I saw a crack in the wall."

After thinking for a moment, Pikachu responded. "There could be another way out."

"Exactly. I'm so sorry I wasn't thinking--"

"It's cool!" Pikachu climbed to her feet. "Let's go check it out."

Their descent back into the ravine didn't feel quite as intense as it had the first time. Eevee felt more confident in what he was doing, and Pikachu's competence at climbing surprised him. In what felt like no time, they were at the bottom of the ravine.

Eevee scooped up the troublesome Thunder Stone. He then gestured towards the hole in the wall. It was tiny-- if either of them were any bigger they wouldn't fit through it. Pikachu went first, curiously stepping into the passageway.

"Huh I guess being small does have its benefits," she remarked. Eevee followed her down the dark, cramped tunnel. It wasn't long until Pikachu stopped. "Light!" she said, happily. The sudden pause caused Eevee to stumble head first into her. His face ended bumping up against Pikachu's tail and his nose was filled with the most heavenly scent.

Soon after they emerged through a gap in a cliffside and into a forest.

"I know where we are," Pikachu said, happily. "We're just around the other side of Shotao Mountain from where we entered Luxo Cave." It was late afternoon and the rest of the day was a blur. Pikachu and Eevee had went to the entrance of Luxo Cave and found a bewildered and relieved Growlithe. As it turned out, the cave-in had been much more substantial than it looked. A rescue party of local Pokémon had gathered, and when Pikachu and Eevee came creeping up on the group Machamp was part way through smashing his fists into walls of crystallized stone.

That evening, Pikachu had proudly shown Eevee her berry stash. They ate like they had never eaten before, and afterwards Eevee built them a nest for the night.

The last thing he did before snuggling up with Pikachu was carefully place the Thunder Stone at the foot of their nest. He was excited to evolve, but there was no rush. The two Pokémon dozed off, content. They were happy to be free, and happy to be together.


Eevee yawned lazily as he rested in the morning sun. He opened his eyes and rolled over, and was surprised to find Pikachu had already gotten up. He sat up and looked around the clearing, but there was no one in sight. He checked for the Thunder Stone-- but it was gone too.

It took Eevee a very long time to trust again. The denial lasted weeks. His friends did their best to help comfort him, but he was certain that something terrible must've happened to his Pikachu during the night. He went searching for her every day. He spoke with every Pokémon who would listen, but his efforts were futile. Over the coming months he finally came to terms with what she had done to him, and resolved to try and forget all about her. On his birthday his friends had presented him with a Thunder Stone which they had banded together to buy from a thrifty Kecleon. He had accepted the present with a smile on his face, and evolved into a Jolteon the very next day. He was a powerhouse, he fought with such strength and ferocity no Pokémon could beat him.

He had moved on and was achieving his dreams. Eventually.

Around that time a Pikachu found herself sitting on a ledge deep in Luxo Cave. Her fling with Manectric hadn't last long, and now she found herself alone again. She wished she could go back to that night. It had been the best night of her life, but following that was her biggest regret.

She had been infatuated with Manectric. Many times had she came seeking his mateship, but every time she was met with a gruff rejection. That was until that fateful day.

"I overheard two Pokémon talking," he had said. "One of 'em says there's an elemental stone in Luxo Cave. Kecleon is paying highly for 'em. Get it for me... and I will let you be mine." She remembered the smirk on his face as she had chued happily at his words.

She was crying now. Her memories seemed unbearable as she looked over the edge of the canyon. A voice snapped her out of her reminiscence. A sad, familiar voice.

"So you came back here too huh? It's good to see you again."
