Work Text:
Red and Green didn't often get the chance to battle together. Being as highly skilled and experienced as they were more often than not they continued to be rivals in battling, as there were no other trainers in Kanto that gave them much of a challenge. Not to say they never played around with the other gym leaders or Elite Four, but... That was just it, playing. When they got serious, they were each other's only option.
So this was a nice change of pace.
In the Battle Towers of Alola, trainers gathered from all over the world, and the bigger pool of trainers meant that they were actually challenged at times, and didn't simply overwhelm everyone immediately.
And they were invited as the special guest champions, so they were allowed (were asked, even) to fight together.
They had never team battled together before, but it didn't take long to adjust. If it was anyone else, Red would never even think of agreeing to team up. He and his team were stronger alone, he'd say. But with Green... Well, whether it was the years of battling as rivals or the years in bed as each other's partner in all else, they were practically telepathic.
While their styles were vastly different—Red was nearly silent and relied mostly on his Pokemon's overpowering strength, while Green shouted most of his commands and generally focused more on strategy—they made up for each other's faults. Red was honestly sceptical they'd find anyone that could beat them even here, but they'd had a couple close calls.
And the exhilarated sparkle that lit up Green's eyes when he turned to Red after another close win... Let's just say they were having very fulfilling nights.
It wasn't just Green getting worked up, either.
Red glanced across from him as Green directed Pidgeot with a command and a complicated flick of the wrist. His presence was impressive, pulling Red's attention from the match. The confidence and concentration he oozed every time he battles... Red felt a wave of heat slowly rise through him.
Distracted, he flicked his wrist with a mumbled command to have Venusaur bind Pidgeot's opponent, temporarily ignoring the Mudsdale it had just struck with paralysis.
This was not one of those particularly close matches, though the opponents were still decently strong. But Green was still taking them seriously, and Red... Was falling in love again a bit, really.
Why was his boyfriend so darn hot??
The image he saw first thing in the morning—Green blinking sleepily with mussed hair in the bright early light of Alola—flashed through his mind. It was so beautiful that it took them another hour to get out of bed, and Green grumbled all the way to lunch about how they ran out of time for breakfast. Red just stared at him and tucked a hair back into place, and every time Green flushed and backed down.
He wanted to go over and do that now, see Green flustered and bashful, yelling things he didn't mean out of embarrassment from being affectionate in public. He wanted to crowd Green up against a wall in the hallway by the elevator, listen to Green frantically whisper in his ear that anyone could pass by there, yet push so ineffectually it was clear he had no intention of stopping Red.
He wanted to go down on Green on the long elevator down the Battle Tower, listen to his complaints cut off into whines and moans as he grips Red's hair tightly and forgets where they are.
"Red!"
His attention snapped back, and with barely a second to judge the situation, he growled out Sludge Bomb and Venusaur jumped back a step, readying the move.
When they won a few moves later, Red was sweating a little, partly because of his foray into imagination, and partly from the adrenaline of focusing back on the battle afterwards.
Luckily, Green was adept enough at commanding Red's Pokemon too, and Red's lapse of concentration didn't affect the match too much (just another thing that made Red swoon to think about). Green grinned forcefully through their after-game greetings with the opponents before quickly dismissing them and storming over to Red, half-worry and half-annoyance.
"What the heck was that?" He started shouting before he got within talking distance. "You're so quiet usually I almost didn't take control in time. What were you gonna do if Venusaur went down just then?"
Green was so gorgeous when he was angry. It may not show on his face, but Red's heart was pitter-pattering in his chest. Without really thinking about it, he reached out suddenly and grabbed Green's wrist, spinning and pinning him against the wall and cutting off any further complaints with a full-on open-mouthed kiss.
Green's struggling to get away melded seamlessly into restlessly pulling and tugging Red closer.
One aspect they shared as trainers, as well as in this, was their relentless aggression.
They kissed until they were both breathless, then Red pulled back for a few harsh pants of air.
"What... was..." Green pushed out with each exhale, incapable of staying quiet. Red drove forward and shut him up again, pressing closer so their bodies aligned.
Green moaned when Red's interest was made clear against his thigh, and he fumbled both hands under Red's clothes, one curling up between his shoulder blades and the other shoving down the top of his pants.
Not to be outdone, Red shifted slightly, then in a second hoisted Green fully off the ground, holding him up by his thighs and fitting more solidly within the V of his legs. This dislodged both Green's hand from his pants and their kiss, but the drawn-out moan Green gave and the way he squirmed to rut up against Red were a perfectly good trade-off.
Circumstances suggested this wouldn't be a good place to go all the way, but Red wasn't interested in waiting. From prior experimentation, he knew it would take at least 15 minutes to get fully out of the Battle Tower, and that was just too long. And he was fairly sure that Green wouldn't appreciate a reenactment of his previous daydream on the elevator, so they'd just have to hope that there were no challengers close to getting to their floor. They usually had at least 30 minutes between matches, if not more.
Arceus, but that self-sure smirk Green gave when he high-fived Alakazam after it flattened the opposing Kommo-o... Red breathed out harshly into Green's clavicle, then bit down for good measure. Green whimpered.
Red had a tendency to bite, and Green's neck and shoulders were often covered in marks. Obviously, it was hard to contribute to that without removing clothing, but just a light nibble on top of clothing reminded Green of the sensation, and he gripped Red's shirt tighter where he was forced to balance himself on his shoulders.
Red hadn't really planned anything, so he wasn't sure how far he was going to take this. About half the time, he started something just to work Green up and leave him hot and bothered, but... This time he was worked up too, more than usual, so that would not be quite as satisfying. That said, they only had about 20 minutes left before a potential interruption, so he had to pick fast.
Red pressed Green harder into the wall, freeing one hand to fumble Green's pants button. Once Green grasped what was happening, he moaned again loudly and added another hand to the cause.
Between the two of them, they both managed to free themselves of the confines of their pants, and Red took them both in hand as Green pulled harshly at his hair, nails digging into his neck and scalp. Green's little whines and whimpers in his ear were magical, and they were both worked up enough that the slide of his hand was perfectly smooth.
Red lipped at what parts of Green's neck he could reach and pumped faster, cognizant of the time crunch. Green's breath sped up, and a moment later he bit Red's ear to mute himself as he came. The bite of pain and the whimpers reverberating in his ear set Red off as well, and he groaned lowly into the juncture of Green's neck and jaw.
As the aftershocks faded, they pulled back, panting and sweating a little as Green pressed their foreheads together.
"What..." Green breathed out, "was that?" Red set him carefully back down, freeing his hands to come up and cup Green's cheek. He stared into Green's eyes, satisfied and smug, and Green rolled his eyes.
"You jerk," Green said, pushing him playfully away so he could straighten out his clothes with a grimace. "You couldn't have waited two hours for the end of the day? If we get another challenger and I'm forced to battle like this, you're making it up to me tonight."
Red smiled. Green knew that wasn't much of a threat, that Red would be happy to "make it up to him" later, but complaining in itself made him feel better, so Red just let him.
Red zipped himself up and took off his hat, knocked askew but somehow not fully off during their tryst, shaking the sweat out of his hair before righting it on his head.
Green frowned at him. "You're lucky you have a hat, I must look like a Rattata's nest," he grumbled, messing his hair up further by combing his fingers through it. Red approached with a smile, wiping some sweat away with the hem of his shirt and molding Green's hair back into a semblance of its regular style. It was still a little frizzy, but no more than might be expected from the heat of the day in Alola. Sure, the Battle Tower was air conditioned, but challengers surely didn't know whether they spent time outside or not.
"Okay?" Green asked, a note of concern in his voice. Red smiled, a tiny little thing that likely only Green could recognize as such. It was so strange how Green could have so much puffed up confidence in everything else, but got weak and hesitant whenever he thought a hair was out of place.
Red kissed his temple, and Green exhaled, some tension going from his shoulders.
They did end up having another battle just before the end of the day, and Green complained the whole way back to their apartment about how gross and sticky it was to battle without properly cleaning up. He made Red bathe him, then fuck him, then bathe him again, which just ended with them fucking in the bath and Green deciding they may as well just shower instead.
