A/N: Proceed with caution, because frankly, all this is, is smut.
Nothing too steamy for now––maybe a few erections mentioned here and there––but you have been warned.
Have a nice day.
He heard the plane before he saw it, and it sounded like another crash landing.
Goddamnit, not again, he thought, eyes shut in irritation. This is the third time in two weeks that that stupid pincushion's been up here to "visit" me, and every fucking time, he has to use that 'I had to crash land because this plane's controls are too confusing' bullshit.
Knuckles remained rooted to his spot on top of the Master Emerald shrine, unflinching even as the sickening crunch of metal on foliage reverberated loudly through the trees in front of him.
The echidna let five minutes pass by before he glided over to the crash site.
Fishing a familiar and unconscious blue hedgehog from the cockpit, Knuckles irately carried Sonic the Hedgehog underneath his arm and headed towards his pseudo-hut near the clearing surrounding the Emerald shrine, the whole time saying nothing.
"You really need to find yourself another hobby," Knuckles barked the moment the blue hedgehog came to, not ten minutes later. "Or at least another island to crash land on. Preferably one that's remote and uninhabitable."
"Ha ha, funny. But come on, you know you love it when I 'crash' here," Sonic retorted, sitting up from the couch he had been lying on. "'Sides, I can never get the hang of that damn plane anymore."
"Oh cut the shit. This is the third time in two weeks! I know you crash that thing here on purpose."
"Well, you're partially right...for once."
"What the hell's that supposed to mean?"
"Nothing. Just that that's the most intelligent thing I've ever heard from you."
"Not like you're some genius either, so shut up, hedgie."
"You shut up."
"You shut up...Don't tell me to shut up."
"Fine. I'm going for a run."
"As you always do."
"It's my thing, dude."
"Whatever."
"Be back in a Sonic Sec!"
The speedy hedgehog zoomed off before Knuckles had a chance to reply, so the echidna just rolled his eyes. He then contacted Tails, who––unsurprised at the news that his big brother was marooned on Angel Island...again––agreed to come by first thing tomorrow morning.
Groaning, the echidna opened his mouth to plead with the fox, but just as quickly shut it. He would rather eat the Master Emerald than spend another night with Sonic, but the sun was going to set soon and––much as he disliked the circumstances––he could not bring himself to have Tails make the journey and the subsequent repairs by night.
Just as he heard the familiar BOOM of the sound barrier breaking, he begrudgingly agreed, earning an apologetic look from the twin-tailed fox.
Ending the call, Knuckles then decided to relax himself and take his mind off of his predicament by punching a few fresh craters into the ground and then taking a bath at one of the island's numerous waterfalls.
He snarled as another thunderous BOOM echoed loudly throughout the island. It was going to be a long night.
Sonic dipped a hand into the crystal clear water and drank, purring softly in satisfaction at the sweet, fresh taste.
After a few more sips and a handful or two to wash his face, Sonic raced over to the cliff on the other side of the small pool and peered over the edge where the water cascaded down into yet another, slightly bigger pool before tumbling downstream.
It was a beautiful and slightly terrifying view. However, he smiled widely as he breathed in the scent of the fresh air and even fresher water, and the strong essence of echidna.
Wait a minute. Echidna? he thought, nose twitching.
Sniffing some more, there was no doubt that the scent of a certain echidna meant that he was somewhere close by. Along with his musk, there was another strong something that smelled quite sweet. Looking down, he could see the echidna in question, lathering the sweet-smelling substance on his body before rinsing it off under the cascading waterfall.
Blood rushed to Sonic's muzzle quickly, the blush burning his cheeks. He tried his damnedest not to internalize the mental image of the wet, soapy, glistening fur of Knuckl–NO, he thought vehemently, as he tried to tear his eyes away from the scene below him.
Even still, he chanced another peek over the edge of the cliff.
"Enjoying the view?" the crimson boy said, nonplussed as he continued rinsing off his soapy body under the falls.
Sonic stammered idiotically before he could reply, "Y-yeah."
"You don't have to be embarrassed about seeing me bathe, you know."
"I know that."
"Then how come you're blushing so much?"
"Y-you saw me?"
"I could hear you drooling from miles away. So of course, when I look up to see the source of the noise, it's none other than the Blue Blur himself checking me out."
"N-no I wasn't!" Sonic, stuttered, blushing further. He pouted, and decided it was better to just change subjects. He desperately tried to feign nonchalance as he leaned over the edge once more.
"Hey, why don't you take a shower at home? Don't you have one there?"
"I prefer the falls, much as I appreciate Tails building that house for me," Knuckles replied simply, stepping away from the water, and––after wiping his face––dove into the pool, swimming towards the far shore.
Sonic, after getting a good, momentary glance at the echidna's wet backside, wanted to see more. His cheeks burned furiously again as he replayed the image of the echidna's soaked ass in his mind.
After a brief mental struggle (one in which his vulgar desires somehow won out), he leapt off of the cliff, sped towards the opposite shore and hid behind the bushes, hoping the echidna would emerge somewhere close by.
Sure enough, moments later, Knuckles came up, though he kept his lower half underneath the water. The blue hedgehog gaped at the glistening red fur that coated his brawny friend, heat rising once more to his cheeks (and unfortunately, his nether-regions) as he imagined what caressing the soft, red pelt would be like.
Though Knuckles made no move to converse with him or acknowledge his presence, the blue hedgehog felt as if the echidna knew he was there, staring at him. Still standing half-submerged in water, he lifted his arms up and began to squeeze his dreads dry, unintentionally striking a sexy pose. Sonic could only gawk further, mouth slowly hanging ajar.
Though it seemed as if Knuckles still didn't know that Sonic was staring at him, to Sonic, it almost looked like he was teasing the hedgehog, as he then began to subtly caress himself as he rinsed off further. Either way, the hedgehog's nether-regions flared with heat.
He couldn't stand it any more. "K-knux, would you mind if I use your shower then?"
Still seemingly pre-occupied with rinsing himself thoroughly, Knuckles grunted, "Go ahead."
Sonic then sped off without another word, glad that he could relieve himself.
Sonic ran a hand up and down his throbbing erection, the other staying put at the base. He moaned loudly and freely, thankful that Knuckles wasn't around to hear his wanton cries. The warm water cascading down on him only served to slicken his shaft and increase his pleasure even more.
He panted the echidna's name more than once; the mental images of a bathing Knuckles were still firmly in his mind.
Sonic moved his hand faster and faster, his wet cock throbbing as he inched himself closer and closer to his climax.
His breathing became shallower as the knotting sensation in the pit of his stomach became more and more unbearable.
On the absolute edge of insanity, he released, screaming the echidna's name to the high heavens.
Knuckles came home about fifteen minutes after Sonic did and, apart from the shower running, heard no sound.
However, as he plopped down on the couch, a can of grape soda in one hand, he heard a muffled cry from the bathroom. And then, his name.
"...Knuckles..."
"Yeah, I'm here. What is it?" he called back.
"..."
The echidna dismissed the call. He opened the can of soda and took a sip.
"Mmm...Knuckles..."
"What, Sonic?"
"..."
"Sonic, I swear to Chaos..." Knuckles muttered irately.
"MMHAA, KNUX!"
"WHAT?"
Knuckles, finally snapping, stood up and stomped towards the bathroom door.
He stopped with his hand on the doorknob as he heard the hedgehog call his name again and...moan?
What the-what the hell is he doing in there? he thought, cheeks flushing. He better not be...oh Chaos.
A part of the echidna wanted to barge into the bathroom, rip the curtains open, and proceed to rip the hedgehog apart. Another part wanted to just leave him alone and let him have his fantasy, however lewd. However, a very large part of him wanted nothing more than to physically be the reason for Sonic to cry out in such a vulgar, wanton manner.
Deciding to trust his groin's instincts, he quietly turned the knob and stepped inside.
Sonic's moans grew in intensity, as Knuckles creeped ever closer to the shower.
He must be getting close, he thought. I'll surprise him once he climaxes.
Moments later, upon hearing the hedgehog practically scream his name for all to hear, Knuckles ripped open the shower curtain...and his face and chest was immediately drenched in a hot, white, and very thick substance.
Sonic stayed crouched in the shower, his cock still standing at attention, even long after he had accidentally drenched Knuckles in cum. He paid it no mind.
He didn't know what to think. Or feel. A part of him burned with embarrassment. Another with fear. Yet, most of his being still burned with desire.
No! Stop thinking like that! Sonic thought to himself. He's probably just washing his face before he kicks me off the edge of the island...if he doesn't end up beating me to a pulp, that is.
While he was still hard, he reluctantly shut off the water, stepped out of the shower and looked for something to conceal his shameful erection...only to gasp in horror at what was left on the towel rack.
Knuckles stood over the kitchen sink, watching as the ejaculate that once clung to his face soon went down the drain.
I know for a fact that he likes me in some way, thought the echidna. I just didn't know he liked me that much.
His internal monologue was interrupted by an angry yell of "KNUCKLES!" before the source of the voice stormed into the kitchen.
Knuckles had to do a double-take at the sight of Sonic. The fuming hedgehog had on the very short, skimpy, white towel Knuckles left behind that barely wrapped around the hedgehog's waist, and the considerable bulge in the middle made it look even shorter and skimpier. Sonic tried (and failed) to hide it.
Knuckles couldn't help but gawk for a moment, loose-jawed, before attempting to stifle a laugh at the ridiculous––though admittedly sexy––sight before him.
"You think this is funny?" Sonic snarled, cheeks stained red in both fury and embarrassment.
"Aww, is the poor widdle hedgie-wedgie still hard?" Knuckles replied mockingly, loving how much more incensed the hedgehog became.
Blushing even further, Sonic advanced, no longer caring that the towel was about to slip off his waist. Both were caught off guard, however, as their lips locked into a fierce kiss the moment they made contact with each other.
After the initial shock though, they curled their tongues together and entangled their fingers in each other's quills for several long minutes before pulling away for air.
"Wha-what the hell was that?" Sonic panted.
"Yo-you tell me," breathed Knuckles.
They dove in for another kiss, though this time for only about a minute. In that minute, however, they had managed to move from the kitchen to the living room (haphazardly enough for the towel to finally slip down), and then crashed onto the couch, where they made out heatedly for a few moments, the now fully-exposed Sonic straddling the echidna's waist.
"Top or bottom?" Sonic asked Knuckles, pulling away as he felt a very warm presence beginning to press into the bottom of his abdomen.
"Wha-" the crimson echidna replied, caught off guard by the sudden question.
"Top or bottom?" the hedgehog asked again impatiently. "Giver or receiver? Seme or uke? HMS Man Sausage or Panama Canal?"
Finally understanding, Knuckles replied, with uncertainty, "I don't know. Your choice I guess."
Sonic, whose incredibly small amount of patience had long since been spent, zoomed out of the room and then came back not two seconds later. This time though, he held something in his hand, which immediately made Knuckles turn beet-red in embarrassment.
"I propose that we settle this through a little game: We watch this while servicing each other, and whoever finishes first has to receive whatever the other chooses to dish out." Sonic said.
"What?" the echidna replied, his muzzle almost blending into his fur as he came around to realizing what Sonic had just proposed. "O-okay, first of all, h-how the hell did you find that? Where did you find that?"
"Knux, the 'hiding all of my extremely personal belongings under a loose floorboard' shit is really cliché," Sonic replied nonchalantly, waving the DVD case with the title "Cumhog: Feeding the Hungry Hungry Hedge-hole" emblazoned on it. "I found this the last time I was here. Not to pry too much, but you don't happen to have a thing for blue hedgehogs, do you?"
"You've pried a little more than 'too much,' don't you think?"
"Never mind that. Well? Are ya game or am I gonna have to dig through that floorboard for another sex game?"
"Do that and I'll knock your ass to the moon."
"With what? Your fist? Or your meat stick?"
"With any luck, both."
"Seems like you're out of luck, Rad Red, 'cause I'm gonna own you, and your ass."
"Is that a threat?"
"Consider it a challenge...for you."
The echidna wordlessly grabbed the DVD, and practically slammed it into the player. The two proceeded to make out momentarily before Knuckles replied, "Challenge...accepted."
A/N: Ownership of these characters are privileges that I just don't have. I mean, if I did own them, everything you see here would be canon (probably). SEGA does have that kind of privilege however, so ask them to make it canon.
Not sure it'll bear much fruit, but hey, no harm in trying, right?
