“Finish it with Fire Blast Aidoneus!” The mega Houndoom did just as he was told, growling a sign of fire into existence before blasting his opponents already hurt Vespiquen to cinders knocking the pokémon out. The rich kid who’d challenged his trainer Rio, someone the canine vaguely remembers the name of being ‘Archibald’, stomped his feet in a tantrum recalling his Vespiquen into its over priced Luxury Ball.
“You got lucky you twat!” The snobbish rich kid said, shoving his pocket change into Rio’s arms, which was hilarious more than most jobs would pay, and ran off, likely to cry about his loss to his parents. Aidoneus bounded over to his master, barking with a smile ready for praise.
Just as he expected, Rio rose up on the tip of his toes so he could reach behind his ears and horns, scratching that sweet spot. “Good job Aidoneus! I think we’re ready to take on Olympia!” Rio’s beaming smile gave Aidoneus a rush of endorphins, happy that his trainer was happy. It also helped with just how cute Rio was in comparison to his less than…cutesy team. He was lithe, below average height, but was pale as a ghost, though that might just be his parents being the epitome of what might be called vampires even if they were just really old school people.
His straight black hair reached just about below his chin, his left eye covered mostly for the look. His clothes were definitely aimed towards an emo aesthetic, a black sleeveless hoodie and leggings alongside some leather boots. And of course his fingerless gloves he used for a better grip to throw his pokeballs. From what Rio had told him—since Aidoneus was a spoiled Houndoom, who hated being in his pokeball unless he needed healing—he did this mainly out of spite of how his parents wanted him to dress. Not that the Pokémon was complaining, he liked how his trainer looked.
“‘Bout time you revert, staying mega evolved makes you tired, right Aidoneus?” The aforementioned Pokémon huffs and rolls his eyes, allowing his form to revert back into his normal one, now at Rio’s chest instead of looming a good head above him. Then again, it gave Rio better access to pet him so he didn’t see the need to complain.
They began their track to Anistar City, like they had been just a couple minutes ago before that overconfident little brat showed up. “I was thinking, Aidoneus,” Rio starts, catching his companion’s attention , “Houn?” Aidoneus questions, Rio continuing his thought right after “after we finish up the gyms and the league, win or lose, I was thinking maybe we could all go on a camping trip to Santalune forest! We only briefly ran through that place so long ago but it was pretty serene, yeah?” The Houndoom’s eyes narrow in thought as they walk. He was still just a Houndour that Rio’s mother had gifted him years prior to the boy actually leaving. So it was fuzzy…
But, Aidoneus did recall the calming forest and the bright rays of light that shined through the canopy of leaves up above. He lets out an affirmation bark with a smile, telling Rio he knew exactly what he was talking about.
Rio smirked, “Alright, good! Wanted to run it by you first before the rest of the party. I know if you didn’t like it you’d burn it down.” He says the last part with a bit of bitterness, and Aidoneus looks away with a shameful smile at the memory of their time in Coumarine gym. May not understand exactly what Pokémon say, but Aidoneus knows he’s absolutely justified in what he’d done.
That Gogoat doesn’t get to say such lewd things about his Rio and get away with it.
Finally reaching the gate of the city, Rio’s eyes caught something, or as Aidoneus could smell, someone familiar. His trainer raised his arm and waved, “Hey Calem!” He yelled and Aidoneus’ mood instantly changed, putting on a far more intense face as they approached the smiling young man that was Calem. “Finally showed up, huh Rio?”
Rio rolled his eyes, “Some rich brat jumped me, it wasn't too hard to beat him though. Money can’t buy skill.” Calem laughed, causing Rio to smile. Aidoneus sneered at that, jealousy bubbling up within him. “I’m guessing you’re here to take on Olympia too Calem?” Rio asks, Calem giving an awkward smile, averting his eyes.
“Yes, but…there’s something else too.” Rio tilts his head, curious. Aidoneus is too, but he’s more anxious, “There’s this diner here, and well…I was wondering if you might wanna get dinner together?” The question hit both Ash and Aidoneus in vastly different ways. To Rio, it was like opening his Pokédex after being in the dark for too long.
To Aidoneus it felt like someone smashed a brick over his head, baring his teeth as he considered where it would hurt Calem most to bite. How DARE Calem try to ask out his Rio? The twerp wasn’t even half the worth Rio was, so what did he think was doing asking out his Trainer? It wasn’t like he’d accept-
“I’m open to dinner.” Rio said. Aidoneus looked up at his Trainer in betrayal, though neither he nor Calem noticed. Calem smiled, yet Ash raised a finger “But I’m not really looking for a relationship right now, Calem. Sorry.” Calem slouched, pouting, and Aidoneus smirked. He knew he wouldn’t humor such an idea, there were far more worthy mates his Trainer had.
“…Maybe, after I’m done with the Gym’s and league, I might be open to a date.” Rio was truthful in that he didn’t want a relationship right now , but that always meant he might desire one later. Gotta get your affairs in order after all. Aidoneus snarls, upset and Rio rolls his eyes, “Aidoneus calm down, we’ll still go on our camping trip first.” Aidoneus quiets only to not embarrass Rio, yet sends the most terrifying death glare he could at Calem, the young man noticing with a gulp.
“W-Well, we can meet up for dinner later. You have a gym to beat, right? I have something to do here before I head there so good luck!” Calem quickly excused himself, running off into the city.
“…Weird.” Rio states, turning to Aidoneus “Time to take care of Olympia, yeah Aidoneus?” The Houndoom averts his eyes for a split second, before returning Rio’s gaze with false joy “Houndoom!” He yells, affirmatively and Rio smiles.
“Then let’s do it!”

Aidoneus was somber on the way into Santalune forest. While the trip overall was supposed to be fun, he couldn’t help but feel saddened by what loomed overhead after the trip. Inevitably, Calem is gonna ask Rio on a date like the shitstain he was, and since the newly declared Champion had completed his goals, it was now a very real, and very scary option.
“What is on your mind?” A defined voice asked, and Aidoneus rolled his eyes, “Nothing Morian.” The Houndoom answered, not looking up at his Bisharp teammate. The Steel-type groaned, “You are going to drag this whole trip down, Aidoneus. Just tell me or I’ll get Sellen to pull it out of you.”
The Fire-type’s head snaps up to look at the Bisharp, “Fine, I’ll spill! Never tell her to do shit like that…” the idea of the Malamar digging through his mind was horrible, and Sellen loved making it hurt, the fucking sadist.
“I…Calem is probably going to ask Rio out.” Aidoneus admits, eyes trained on Rio walking on up ahead, having a one sided conversation with the team's Scolipede, Henri, the bug horse clearly bored of whatever topic their trainer was talking about it. “So? I see no issue besides the fact Calem is Calem and you don’t like him.”
“He doesn’t deserve him, Morian!” Aidoneus snaps, and the Bisharp’s left eye widens, his way of raising a brow. “Alright…then that’s the issue? You’re jealous?” Morian bluntly says, and the Houndoom stutters, “W-W-What?! I never said I was…shut the fuck up!”
“Didn’t need to say anything, Aidoneus. It’s clear that’s the issue, you want him…you also want him in your dreams if your sleepwalking is anything to go off of.” The monotone voice he used with that part sent embarrassment throughout Aidoneus’ whole body, “I talk in my sleep..?!” He growls in self focused frustration, and Morian simply hums affirmatively.
“Yes, and clearly there was a lot more to those dreams than just wishing for him to be a maye. Clearly you were…indulging in them, to say the least.” Aidoneus chooses not to say anything, simply wide eyed and embarrassed.
“…Aidoneus, of all of us you’re the one who's known Rio the longest. Do you honestly believe you could prove a better companion than one of his own kind?” Morian inquires further, and the Houndoom laughs, “Yes, I do. It’s not as if trainers don’t have relationships like that with their Pokémon. You remember that lady we saw her Lickitung back in Couriway town right? They were too obvious. It’s just I don’t have the chance Morian, with this trip we’re all gonna be out and about-“
“I’ll give you a chance.” The Bisharp states and Aidoneus slows a bit, Morian doing the same so they can hang back behind the rest of the group. “Why? And how?” The canine asks, too paranoid to accept the fellow Dark-typed offer immediately. “Aidoneus, we all know you have a burning desire for Rio and a far stronger bond with him than the rest here. I’m going to give you one good chance not to be a coward .” His voice stern and assertive, wanting to make sure the hound listened, “We’re gonna be here a few days, so just tonight I’ll convince everyone to walk away from camp and give you the night alone with Rio.”
Aidoneus wasn’t sure what to say. Most of the team was friendly with one another, with certain team members liking and disliking one another to different amounts. For a comparison Aidoneus considered himself and Morian to be in a friendly rivalry, and as such was confused why the other Pokémon would assist him in such a way with no other conditions. “Well…thanks.” Is all he can really say.
“Are you two finished gossiping?” Lapis asked, the shiny Vaporeon looking smug at their feet. Aidoneus growled, “Mind your fuckin’ business. Don’t you have a Dragon-type to get fucked by?” The Water-type scoffs, then smirks, “So what if me and Percy fuck? I don’t care about your input on it. Though, I will say…try not to be a pussy tonight.” With that he smugly walks off and Aidoneus groans. “He’s gonna tell fucking everyone…”
Morian hums, “Makes my job easier.” Aidoneus groaned, but silently agreed.
Whatever it took.

Morian had done just as he said, convincing the rest of the team to walk away to give Aidoneus and Rio the night. They even managed to get Percy out of the nearby lake too, as impossible of a task as that sounds due to the Dragalge hating being out of the water for any period of time. Though he assumes that the promise of alone time with his favorite little Vaporeon was enough of a draw.
Aidoneus meanwhile, was standing in front of Rio’s tent, and judging by the light coming from it he assumed the Trainer was either looking at stuff on his Pokédex or reading a book by lamplight. Regardless, the hound steeled himself. This was his one chance, his one shot at showing Rio just how much he cared about him, and he wasn’t going to let it go to waste. Aidoneus lets out a huff and approaches the tent, pawing at it and growling.
“Houndoom.” He says plainly, getting Rio’s attention based on the rustling he heard within, the zipper to the entrance to the tent was undone and Rio’s peaked out, the only thing he was wearing apart from the oversized band shirt were some panties, which he swaps his briefs out for when sleeping for more comfort. It made it hard for Aidoneus to keep his eyes on Rio’s face.
“Oh, Aidoneus! Guess you’re tired, yeah?” The Fire-type didn’t really want to lie, but nodded. “‘Kay then, I’m gonna stay up a bit more to read but I don’t mind you getting comfy now.” Rio moved aside a bit to help let his best friend in before zipping up the tent. Thanks to the fact that most of the Pokémon on his team could give less shits about shelter, he could afford to splurge on a big, roomy tent. It had some small pillows, a sleeping mat, and a blanket, all able to be carried thanks to Henri.
Rio lays back down and waits for Aidoneus to curl up at his side, yet that never comes. He looks up at his partner, “Uh, Aidoneus? I thought you were tired?” The hound growls, shaking his head, eyes showing his anxiousness, “Houn…!” Rio can hear how Aidoneus' normal little quip is full of longing.
“A-Aidoneus…what’s on your mind?” Rio asked, sitting up, concerned something was wrong. Rio could only watch as his closest friend slowly lifted a paw and set it on his upper thigh. The young man awkwardly smiles and chuckles, confused.
“I…don’t think I understand, Aidoneus. Wish you could just speak to me straight up like Selen can.” The Houndoom growls, “Houn! Houndoom!” Trying to get his message across, his other paw lifting to Rio’s hip yet only seemed to confuse Rio further. “Aido, c’mon, watch the underwear!” He chastised with the use of a nickname. Aidoneus was angry, and he agreed with Rio’s earlier statement, it would be so much easier if the Pokémon was capable of human speech. Technically, he could learn, like he’d heard other Pokémon achieving before, but it’s not like he had the time to when he only realized he desired Rio in such a way maybe a few weeks ago.
He…he had one more shot at this. One last idea to communicate despite the lack of his ability to talk to the cute fucker!
His paw that was on his hip raised up and shoved Rio’s chest, forcing him to lay on his back. “Aido! What the hell are you-?!” Then, Aidoneus did the last thing he could think of, the only thing he believed would be able to communicate what he wanted, what he needed .
He kissed Rio. It was sloppy, and awkward, due to their different mouth anatomies, but he kissed him regardless. Rio was taken aback, utterly flabbergasted by what Aidoneus was doing. But, as he felt Aidoneus’ tongue press against his lips, he felt himself willing to reciprocate. He opened his mouth letting their first kiss deepen. Rio lifts his hands up to caress and grip his partners horns, pulling him closer.
Aidoneus could cry, and he was certainly growling in pleasure. His partner, the one he desired as a mate, was reciprocating his advances. Even if he could speak like a human, he wasn’t sure if there were any words in existence to describe how joyous he was.
Eventually they seperated, panting for air, a string of saliva connecting the two. “A-Aidoneus…” Rio whispers breathlessly, “I…I didn’t know. Was…this why you huffed and puffed when Calem asked me out?” Aidoneus nods, but hates his teeth at the man’s name, his Trainer getting the idea immediately. “Alright, won’t mention him.” He rolls his eyes, but yelps when he feels Aidoneus trying to claw off his panties, “L-Look I get you’re all hot bothered, but at least let me take it off!” Rio negotiates, pulling off his shirt.
Aidoneus doesn’t listen though, moving down so he could see the thing covering his mate's privates. He frowned, and then opened his mouth and bit into the soft fabric. Rio’s eyes go wide, “H-Hey! Aidoneus don’t you fucking dar-!” RIP.
In one fluid motion Aidoneus literally tears the undergarment off of his Rio, spitting out the remains. He hears Rio curse at him half heartedly, cleared flustered as Aidoneus examines his privates.
While his Trainer may’ve been below average height wise, he certainly wasn’t dick wise. He was, for lack of a better comparison, hung like a Rapidash. Well by human standards. His smooth crotch helped Aidoneus appreciate just how big it was. Maybe if he wasn’t intent on showing Rio just how badly he wanted him, he might’ve let him take the Reid tonight.
But not today.
Instead, he lowered his snout to sniff Rio’s balls, his tongue lapping at them and earning a moan from the man. “F-Fuck, Aidoneus…” that made the hound smirk as he dove lower, his tongue now lapping at the rim of Rio’s ass, getting him ready for the next step of the night.
“Ohhh shit…why’re you so good at this?” Rio groans, gasping as Aidoneus goes even further as his tongue pushes into his ass, tasting his insides. Aidoneus couldn’t get enough, having waited for this for longer than he ever wanted to. His front paws nudge Rio’s sides, “W-What- oh fuck…what is it Aido?” Aidoneus makes the best “roll over” gesture he could with a paw, and is thankful Rio seems to understand, getting on his hands and knees so Aidoneus can better eat him out.
It goes on and on, Aidoneus pulling away for a moment to admire how shiny and loose Rio already was. Sure, he could get to penetrating him now, but…fuck that. This is their night, and he’s going to enjoy it. He shoves his tongue back in, getting his mate to moan, “Oh my A-Arcues, y-you’re hungry, huh?” Rio shakily chuckles. His cock’s rock hard, he honestly this is probably hotter than anything he’d ever imagined and he also means that literally cause FUCK is Aidoneus’ tongue hot…in fact it’s so much his arms give out faster than he thought, so he instead using them as a pillow as he lays his head down. Giving Aidoneus better access to his ass given how it was now stuck up in the air.
‘Fuck what does his cock feel like?’ The fact Rio was already wondering that made it clear how into it he was. And, eventually, Aidoneus pulls away satisfied. He licks his lips and steps over Rio, his front paws thudding next to Rio’s head, pressing his warm body against Rio’s back. The man groaned at the heat pressing into him and then froze, as funny as the idea was.
Rio could feel the burning heat of Aidoneus’ shaft against his, and judging by the imprint of the searing heat it is roughly just as big as himself, if not a bit longer. “B-Be-“ Rio has the air knocked out of him as his partner rears back and shoves in in a quick fluid motion. “FUCK!” Rio screams, gritting his teeth, Aidoneus only giving him a few seconds to get used to it before pulling out and thrusting back in. Aidoneus pants, howling in pleasure as he leans down to nuzzle his face against Rio’s cheek.
“O-Ok Aidoneus, I need you t-to slow dowwh fuck…” he groans as Aidoneus buried his cock deeper and deeper into him. If it wasn’t for how affectionate he was being by nuzzling him he might’ve thought Aidoneus didn’t care about him, at least based on how rough he was being. It was was a lot, too much, and as his body rocked Rio could feel his cock slap against his stomach, his first climax drawing near as the roughness Aidoneus was using proved too much.
“Aido…! I’m gonna cum…!” Aidoneus growled softly before gently biting into the crook of Rio’s neck, “ Houn…” he whispered through his clenched teeth, hearing Rio scream and tighten around him. The scent of Rio’s cum filled the tent as his mate sprayed his first, and absolutely not last, climax. Aidoneus figured he might as well go a bit harder, since he was certain Rio had gotten more used to him by now.
Rio barely had a moment to collect himself before he felt his partner start speeding up, “Arcues Aidoneus! D-Do you not get- fuck! Tired?” Rio’s legs spread out a bit more, making it easier for his hound to slide in and out of him. Eventually he could feel Aidoneus’ girthy knot start slapping against his hole. Rio expected that his Fire-type would want to savor the moment longer, but was left shocked silent and cumming once again as the Houndoom forced his knot in with a POP . “Fuck, fuck, fuck…!” Rio moaned, as he felt his liver growl and then howl, briefly pulling away from his mate's neck as he let loose inside him, filling Rio with his cum. Something he once only dreamed of.
Both were out of breath as it happened, Rio groaned at the feeling of being stretched so much. He felt Aidoneus huff and then started to pull out, and the man had to grit his teeth as his ass stretched and stretched before Aidoneus’ knot pulled free…and he started thrusting again. “A-Aidoneus, holy shit w-where’s all this stamina c-coming from~!” Overstimulation was starting to get to him, and it was becoming harder to focus on anything other than the red hot cock sliding in and out of his ass. That’s when he made a mistake, by complete accident as he tried to move his arm to sit up a bit, he didn’t notice that the hardcore sex they were having had made his backpack fall over, and with it, his mega ring.
And as such, when Rio’s arm slipped due to the tents floor being less than ideal flooring, his hand, perhaps by the grace of Arceus himself slipped over his fingers. Rio’s eyes widened as the key stone in it flowed brightly, “Oh fuck me.” As if that wasn’t already happening. He heard Aidoneus howl overhead, and he craned his neck back to see Aidoneus’ Houndoomite necklace glowing as the familiar glow of a mega evolution enveloped him. And as his partner's form grew, so did the dick in him.
It was unlike anything he’d ever felt before, the length and thickness almost doubling as Aidoneus roared, his mega evolution completing. He looked concerned through, trying to pull out of Rio out of fear it hurt him ” Don’t you FUCKING dare pull out, Aidoneus…” the commanding voice sent shivers through the canine, not expecting that tone of voice. “You started this, and now you’re gonna finish it . Now fuck me as rough and hard as you want to until the sun rises!” Almost immediately Rio found he regretted those words as Aidoneus growled and began to ruthlessly pound his trainer, fucking him silly and lifting a paw onto his back to keep him in place, his red hot claws causing Rio’s skin to sizzle lightly.
Focusing he made sure he would give him any nasty burns by limiting that hit, yet what Rio managed to spit out next made something snap deep within him. “Fucking… mark me! Claw me, bite me, I don't care, just show me how much you want me to be yours!” Rio had never spoken like this before. But he was now. For him, for Aidoneus. Just as Rio suggested, he raked his claws lightly across Rio’s back while driving his cock in and out mercilessly. Thanks to the heat of his claws, they seared the claw marks closed. It all made Rio cry out in pleasure as climaxes again, tightening around the Fire-type which just spurned him on to fuck him harder and faster.
More marking. Some on his waist, more on his back, a couple on his butt. Then he moved to biting, most of them were just pricks, but he knew that he would absolutely sink his fangs into Rio to really mark him as his. Aidoneus had waited long enough, and he would not be denied claiming his mate any longer. His knot slapped against Rio’s hole once more, this time a lot bigger and a lot more threatening. It’d be a miracle if the young man could walk tomorrow. Guess they’ll need to pray .
He just keeps thrusting away harder, faster, rougher, almost as if he didn’t care about Rio’s wellbeing. Yet, of course, that was not the case, he simply knew, as of know, that man liked it rough. And rough is exactly what he would give him. Aidoneus set a brutal pace, milking orgasm after orgasm out of the man under him not giving him a moment's reprieve. Rio could only really moan, and watch as Aidoneus’ literal mega cock bulged out his stomach to just above his belly button.It was intense, it was hot, and it hurt-
But it hurt so, so good…
Sadly all things, no matter how good must come to end, and that came in the form of a mega Houndoom’s giant fucking knot
“Houn-DOOM!” Aidoneus howls, pushing hard, bending down to sink his teeth into his mate’s neck, marking him. Rio’s overstimulated mind simply gritting his teeth in a hissing moan as he feels it stretch him wider, and wider, and wider-
POP
They both cum, hard. Rio is crying at this point, babbling simply due to how overwhelming this all was, yet he couldn’t think of anywhere he’d rather be. Aidoneus felt much the same scratching the former part, and thrust gently as he filled Rio again. It went on for minutes until Aidoneus finally ceased unloading.
The two lay there for a long moment, Aidoneus careful not to stab his mate with his spikes, and Rio manages a smile. “T-That…that was…yeah…” he sighs, but hears Aidoneus…laugh? Aidoneus gets back on his legs, and starts grinding and Rio remembers what he said.
”Fuck me until the sun rises!” he looks over at the small mobile clock he brought that read, mockingly 1:09AM .
’I am so…utterly fucked.’ is the last rational thought he has that night before Aidoneus continues ravaging him, taking them both to a pleasurable, hazy space where it’s just the two of them.

Morian walked back to camp with everyone else where they were all assaulted by the familiar smell of Poké-cum. Particularly that of a desire filled Houndoom’s scent. He saw Henri recoil first, the bug type’s normally slender and serpentine eyes widening comically “Holy shit-!” he exclaimed, Selen being the next as she gagged “I know you said he wanted to bed Rio, Morian, but not to such a vulgar degree!” She dived into the nearby lake, hoping to escape the stench there. The rest of the team still standing didn’t actually care all that much “You need to actually use that horse cock you got there Henri, this shouldn’t be bothering you.” Lapis states, and the Bug-type scoffs, “Not all of us care about getting railed, or railing someone you horny purple weirdo.” The bug horse argues back, which gets Percy’s attention, “Leave ‘em alone Henri, even if it's a little rude, he has a point. We’re Pokémon, this shouldn't bother us.”
Henri sighs, but nods in agreement, “Yeah…just not used to it. Hope I don’t have to though, I mean, how long were they fucking?” Henri wonders aloud and Morian seems to agree, “Let us find out.” He says, moving to the tent stinking of sex and cum of both human and Pokémon. He kneels down, unzips the zipper and peers inside, spotting both his Trainer and his teammate curled around each other.
Rio is covered in claw and bite marks, his hair an utter mess yet has a dopey smile on his face, holding the Houndoom currently laying on top of him, not fully asleep, but still very much tired it seems, “Aidoneus-'' the canine Pokémon shoots the Steel-type a death glare, and that get the message across. He zips the tent back up and walks back to his teammates. “So?” Lapis asks.
The Bisharp hums, “Well firstly, don’t bother them right now, I’m pretty sure they want to sleep in.'' He walks over to a tree and hits it hard, dropping a Citris berry from its branches which he catches. Morian leans against the tree and eats, “Ohh, and Henri? You’ll likely be carrying Rio around today.” He states taking another bite.
The Scolipede groans, “And why’s that?” he questions, making the Dark-type chuckle.
“I am not confident in Rio’s ability to walk, today.”
