-Falling Into One-

The rapid clicking of keys can be heard in the room as Tails types away on his computer. Cosmo is busying herself with tidying up the place and happens to stumble upon a little wilting plant. She gains a sympathetic expression and puts away the bag of cheese snacks she's holding.

She begins to sort of mess around with the flower. Well, mess around aren't the right words—more like bring it back to life. A kind of green aura forms from her palms and pulses into the plant as it begins to stand taller, more healthy and alive. Soon after, her soft, feminine voice sounds quietly in the room.

"Hey there, little guy, what's wrong?" She pauses for a moment as if waiting for an answer only she can hear before speaking again. "Oh, you just want a little more sunshine. I can help you with that." Her response is sweet as she lifts the flowerpot off of the desk and on to the windowsill, closer to where the sun shines when it rises into the sky. "There you go—now you'll feel all better." Her smile is radiant, as if saving the life of that plant was the most fulfilling thing in the world.

Tails, having looked up when she started speaking, appears absolutely amazed. "You're really something, Cosmo," he comments sweetly.

She turns to him as if remembering his presence and flushes in embarrassment. "T-thanks, Tails." She walks over to him and puts on a stern face. "You know, you should be getting to bed too."

He looks sheepish before his outward appearance becomes serious. "Not right now. I've just come up with an idea I should have thought of ages ago. Since Eggman has the information on the prophecy, I'm going to hack into his system and get the info from there."

She relents with a sigh. "Okay, fine. Good luck."

"Thanks." I'll need it. His thoughts radiate uncertainty.

His focus solely lies on the screen in front of him as he opens up a window to begin trying to break into the remote system. After a while he makes the connection and sighs in relief. Okay, so now I have to try and figure out the password. What could it be? he wonders as he begins trying things that might work.

Eggman. INCORRECT

EggmanRules. INCORRECT

Robotnik. INCORRECT

Sonic. INCORRECT

Feeling a little frustrated, he tries something random.

IHateThatHedgehog. CORRECT

Raising an eyebrow, Tails shakes his head in disbelief but accepts his luck. He begins to search around for the file and smiles with glee when he notices one labeled "Aquatic Ruin Prophecy." It's from Aquatic Ruin Zone?

Filing that thought for later, he puts in the password again, and that's when all hell begins to break loose. Oh, no! He's on to me! He knows this because Eggman's insignia pops up onto his monitor and a little screen displays, showing a progression bar reading: Deletion In Progress: 5% Complete.

"No! It was a trap!" he cries in alarm, seeing the data of his computer slowly starting to be erased. I have to close the connection or I'll lose my computer! he frantically realizes as he begins the processes of closing off the link.

7% Complete. "Urgh…" His fingers are a blur on the keys until, finally, he's out of Eggman's system with only 10% of his system wiped.

"Tails… what happened?" Cosmo hesitantly asks after having watched everything occur, but she didn't want to interrupt for fear of making things worse.

He sighs warily before looking up into the cerulean eyes of his mate. "Eggman set up a trap knowing I would eventually try to hack into his system to get information. But he was stupid enough to name the file after the prophecy. Now I know where it comes from, and we can go to Aquatic Ruin Zone to find it ourselves!" he excitedly explains.

Cosmo nods in agreement before speaking. "Okay, but it'll have to be tomorrow."

The kitsune pouts but agrees. Just as he stands up, they hear a thump from upstairs. "What… was that?"

Cosmo seems curious as well, and the two head up the steps to investigate.

~XxoOoxX~

Why do I feel so hot…? I pant and twist on the bed sheets, thankfully not waking Shadow. His scent is practically wafting in the air, tantalizing me. Smells so good…

I turn to him and bury my face in the crook of his neck as I inhale and shudder. Without much thought, I climb on top of his body and settle there nicely. He's so warm and soft. My lips latch onto his neck, where I begin to suck and kiss slowly. My legs settle on either side of his waist as I accidentally lower my hips to meet his.

My whole body trembles as I whine softly, feeling my ears lower at the sudden sensation. What was that…? I move my hips again, almost against my will, and weakly clutch onto Shadow at the wave of pleasure that follows suit. "Ahh…"

I nestle my face more deeply into the fur of Shadow's neck, moving my hips against his rhythmically. W-what am I doing? Why does this feel so g-good? I whimper and mewl when I feel my length beginning to unsheathe and make contact with the warm member of Shadow.

He shifts and groans a bit, but I stay latched to him, grinding our lengths together, something I never thought would feel this amazing. My mind is so hazy, all I can think about is how hot I am and how touching Shadow like this makes the heat a bit more bearable.

"Mmm… S-Shadow…" I moan lowly and feel a wetness begin to leak from my member.

My face, which was already hot, feels like it's about to burst into flames at what might have actually been oozed. Shadow's deep groan alerts me to his regaining of consciousness, and I have no way of even stopping my motions—even if I wanted to.

I see his eyes open blearily, clouded with confusion and… the beginnings of panic? Even with the haze of this heat, I can still understand that something's not right.

Suddenly being pinned with my wrists next to my head and staring into the angry confused eyes of my mate confirms this immediately.

~XxoOoxX~

Where am I? What's going on? If it's those damn GUN agents again, I'll show them not to mess with me…! I grab the offending person and flip them on to their back, ready to finish them off, when a delicate whimper reaches my ears.

No way would they show such signs of fear around me—unless, of course, I start breaking bones. I try to focus on the person below me, slowly regaining focus. I smell vanilla and mint, such a nice combination. It's practically polluting the area we're in. I seem to remember that scent…

Just when I get the idea of who is under me, his voice whines needily, "Shadow…"

The very sight of him sets my blood aflame, his face flushed and his lips releasing pants and little whines and whimpers. I've never seen such a delicious vision. Practically on its own accord, my lip curls over my teeth, allowing a fang to show as I smirk. I bend down to his slightly twitching left ear and speak in one of my deepest intones, "What have you been doing, hedgehog?"

He whines and twists helplessly in my grip, feebly trying to raise his hips up to meet mine. "Shadow… please. I'm s-so hot… I need you." His voice really is full of need as he begs; the very sound strengthens my arousal, and whatever warning bells about giving him what he wants seem to disappear.

"You need me, huh, Sonic?" I ask huskily, starting to lower myself.

"Y-yess, I—ahhh… Shadow!" He mewls loudly as I begin to rub our lengths together. A hiss escapes me through gritted teeth at the glorious feeling, and I dive down to claim his lips vigorously. I feel his arms try to weakly escape my grip as I keep him in place, holding him steady for my thrusts as I messily reconnect our lips, savoring the taste of his mouth.

"Ugnnn…" He groans and whimpers as I bring pleasure to his body. The feeling of saliva beginning to trail along the corner of his lips causes me to break away and make a path down his muzzle with my tongue. Dear God, he's like a forbidden fruit… something I shouldn't have, but I can't help but plunder…

I groan as he matches my thrusts and begins to weakly cry my name. The fire raging inside me settles low in my groin, and I realize sluggishly that I'm close to bursting.

I pant and fight against the almost painful building of pleasure, knowing from my studies that there's a much better way to find release… Giving one last thrust, I pull back only to feel wet liquid splash across my lower abdomen regardless directly from the beauty I was stimulating vigorously. I guess I didn't stop fast enough for him…

Looking at my beautiful sapphire Chaos Bound, I can see that his face is pinched almost as if he's in pain, but the kittenish whine he gives as he releases tells me otherwise. I nearly follow suit, despite my efforts to hold back anyway at the mere sight, and have to bite my lip and take a deep breath to calm down.

His chest rises and falls quickly as he catches his breath. When he finally opens his eyes, he looks embarrassed. "Chaos… What did I do?"

I chuckle deeply and lean down to leave kisses slowly along his neck, speaking between kisses as I do. "You had an orgasm…"

He inhales softly and swallows. "H-huh?"

This causes me to laugh again. His naïveté on the subject is oddly attractive to me. "Do you know what sex is, hedgehog?"

He thinks for a moment while I begin to trail kisses along his collarbone, specifically his Mark when he shudders upon contact with it. "Umm… not really? I-I just know you're s'posed to wear a condom so you don't impregnate a girl. I-is this sex?"

I bring my face up to gaze into his curious yet lust-laden eyes. "No… this is more along the lines of foreplay… Would you like me to show you what sex is? Although, I prefer to call it 'making love'…" I feel like we're not supposed to be doing this for some reason, but things are becoming so cloudy all of a sudden.

His face flushes crimson and his ears lower when he responds meekly with, "Yes, please…"

I don't need any more incentive than that. Nestling my lips into the fur of his chest, I find a swollen nub and start to lick and suckle, hoping to hear more delicious calls and cries from his lips. He doesn't disappoint, and just the sound of his voice has my length dripping pre-cum.

My hands bring his together above his head so that I can clasp them with one hand, freeing the other to do whatever I please. My free appendage rubs along his sides slowly, moving up towards the other nipple where it twists and teases it.

The feel of his newly revived length against my stomach makes me want to taste something different. Leaving the abused nipple and hearing his whine of disappointment, I laugh to myself at the surprise he's about to get. You won't be so disappointed after this, hedgehog…

His scent is sharp and mouthwatering when I finally reach my target, and although I've never done this before, I'm very eager to begin taste-testing. As I try a slow lick against the sticky warmth, the pungent contrast of sweet and salty assaults my senses and has me wanting more.

"Sh-Shadow! What a-are—?" My mate groans deeply in confusion and pleasure, subconsciously bucking his hips up to gain more of the feeling.

Not wanting him to move as I give him sensual gratification, I remove my hand from his nipple and place it firmly on his hip instead. "Just enjoy the ride, Sonic…" I purr then turn my eyes back on the prize, taking the flushed tip into my mouth, wary of my larger-than-normal canines.

He cries passionately and begins to writhe helplessly as I take more and more into my mouth, making sure to suck and lick along the smooth skin of his member. Pre-cum gushes into my mouth, even more potent than the taste from before, causing me to groan and buck my hips against the bed sheet desperately. I need to be inside of him. Now.

Pulling back from his glistening length, I ignore his cries for more and turn him gently yet firmly onto his stomach, almost instinctively, wanting him in proper mating position. Now, I've only studied about male/female mating aboard the ARK, so I don't know much about how to do this… Looking at his lowered torso and elevated rear, his little tail raised, seeming to taunt me with the puckered opening below it…

Grinning wickedly, I slowly begin to tease his tail as I gently twist it around my finger, bringing my face closer to his newly discovered opening.

"Mmm… Shads, what are you doin'?"

Instead of answering, I pass my tongue across his opening firmly, causing him to gasp and jerk. "Ughnn, Shadow! S-stop! Y-you're not supposed to—"

Disregarding his weak protests, I press my tongue inside the tight heat to hear more of his moans and whimpers. "Shads… ahhh… d-don't touch there… mmm…" Despite his objections, he pushes back against my tongue, wanting a taste of what I plan on giving him.

Giving a last roll of my tongue, I deem him well lubed and pull back, eagerly ready to plunge into his snug opening. I climb on top of his panting form, making sure to line myself up and nuzzle my face next to his. His eyes are squeezed shut, his mouth left open as he gasps for breath. Giving a throaty laugh, I tell him, "I suggest you brace yourself, hedgehog. This is going to be a bumpy ride."

My hips snap forward, and the world seems to fade away. All that matters is the hedgehog below me, the tight heat that surrounds me, and the connection between us.

He trembles beneath me, a little cry escaping him. "Chaos, Shadow!"

I groan, pull my hips back, and slam back in, positively loving the way he feels. God, I can do this forever. Almost without thought, I begin to increase my pace, his body arching into my thrusts gracefully, adding to the pleasure. His hands tremble as he claws the sheet, screaming and begging for more.

"Shadow! Shadow, PLEASE! Sooo good… Ohhhh…"

Fuck if I don't come just from that. I pant in exertion, nearly pounding into him at this point; the sound of the headboard hitting the wall falls on deaf ears.

"OH, CHAOS, SHAODW! Right t-there! Feels good… ahhh… r-right there…"

His screaming moans and tightening entrance let me know that I found his sweet spot, and, wanting to please him, I aim just for that place. His smooth, almost slick heat contracting around my length forces me to bury my face into his relaxed quills as I groan deeply. "Sonic… God, I love you…"

His arms give out on him, and he sinks his face into the pillow below him. "Shadow… Shadow, I love you…. please… mmm…"

We're both so close, and my heart is pounding ridiculously fast. Wanting to drive my Bound over the edge first, I begin to thrust harder, faster into him, his body willingly taking everything I give.

"Fuuuck!"Sonic cries loudly as I relentlessly hammer into his pleasure point.

"Language," I growl throatily into his ear before nipping it affectionately. I know I should be a bit gentler in this first joining, but my instincts are demanding that I dominate my submissive, that I claim what's mine…

Suddenly my eyes lock onto the section where his neck meets his left shoulder. Trailing my nose along it, I inhale his vanilla, mint-like scent, feeling my mouth water. My tongue laps the area of its own accord, resulting in Sonic's shudder and him exposing his neck more for me to…

~XxoOoxX~

What is he doing to me? His hips slam into my rear again, pulling a strangled moan from my throat.

Chaos, who would've thought being pounded into would be utter bliss? I should have done this ages ago… Shadow groans into my head quills as his thrusting motions pick up pace. Okay, so w-waiting was definitely the right choice…

I can barely breathe with all the moans and whimpers that leave my throat nearly every second. His forceful thrusts make it hard to hold back… A particular strike causes me to tear the bed sheets to ribbons below my hands, my member twitching and leaking more of that liquid from before, forming a nice puddle below me.

Oh, Chaos, please don't ever let this end… My length is so hot and swollen, absolutely ready to burst from the constant stream of pleasure. The carnality is almost painful as he hits that spot over and over and over again. My eyes become teary as I hold the remains of the sheet for dear life, allowing the heat inside me to become near agonizing. Ohhhh, that feeling is s-so close…

"Ahhh-ahhh-ahhhh!"

I feel his tongue begin to trace along my neck again and immediately tilt my head to allow him better access. Anything to make this never end…

His teeth scrap against my skin, causing a hitch in my breath. What is he…? There's more pressure, and I realize he's about to break the skin with his sharp teeth. I don't even feel a hint of panic rise in my system, oddly enough—just the near snapping of that pressure building inside me.

Then he bites.

I thought it would feel painful, but it's the exact opposite. I'm so far up in ecstasy that I black out for a moment, not even caring about the earth-shattering scream I emit upon release. The only thing I notice is his essence seeping into me. Not just the liquid warmth that fills me down below in thick milky white spurts, but his actual Chaos energy. It's like having my pure energy tainted by a bit of his darkness.

I love it.

Soon after, his heavy weight sinks onto me, and we collapse onto the bed in a sweaty, sticky heap. I moan tiredly and feel him lap the blood lazily from my shoulder. Slowly he extracts himself, much to my displeasure—I love the feel of you inside me!—and lies down beside me.

I weakly lock eyes with him and notice the vibrant shine in his blood red orbs. "Did you like that?"

Giving a satisfied chuckle, I purr, "Like that? I loved it. I want to do it again and again… over and over." Just the thought sends a tingle down my spine and a streak of arousal in my system. The heat was doused for the moment, but it's slowly beginning to rise again…

"Hmm… Well, whenever you want to, I'm more than willing to give you what you want…" he agrees huskily.

Feeling my heart beginning to speed up again, I slowly crawl onto him, forcing him onto his back. "Yeah?"

His hands grasp my waist as I settle my legs on either side of his body. "Yeah."

~XxoOoxX~

Two twelve-year-old pre-teens stop outside the door the alleged sounds are coming from. Twin expressions of concern blossom on each of their faces as a particularly loud bang reaches their ears.

"Do you think they're okay? I mean, what could be going on?" Tails ask the Seedrian next to him, the tails behind him swishing in anxiety.

Cosmo raises a hand to her mouth in worry as she speaks. "I don't know, Tails. You think we should go in?"

He looks hesitant for a moment before determination sets in and he nods. "Yeah. If they're being hurt, we should help them!"

He grabs ahold of the nob when a loud moan sounds from the room. "Shadow!"

Having never heard his brother's voice sound like that before, he removes his hand from the nob slowly in uncertainty and unconsciously begins to blush.

Cosmo's face resembles his as she widens her eyes. "Are they…?" she asks slowly.

"S-Shadow… soooo good… ahhh…!" the loud cries sound, making them back away in embarrassment.

"Y-yeah. I think we should—"

"Yeah."

In agreement, the two rush down the steps and back towards the basement, away from the room containing the two hedgehogs.

~XxoOoxX~

Clangs and bangs can be heard as the Doctor makes some final improvements to his machine. After he screws in a bolt, a mechanical voice interrupts him. "Doctor, there have been some developments."

Dr. Eggman puts down his screwdriver and turns to the small silver flying bot. "Yes. What is it?"

The bot hovers for a moment before speaking. "The fox hacked into your system but was forced to flee due to the trap you set for him."

Chortling, the Doctor smiles maliciously. "I knew he would eventually. Serves him right for trying to stick his nose where it doesn't belong. Is that all?"

The bot waits for a movement, as if contemplating, before speaking again. "There has been progress with the two hedgehogs."

This causes the evil genius to hop up with surprising agility. "Really? I must see for myself!"

The bot watches as the Doctor exits the room, almost appearing to gain a sweat drop before following after his creator.

Quickly turning on his monitor, Eggman begins to examine the screen before him. His face is at first puzzled, then his eyes widen, and he all but screams as the horror sets in. "Turn it off! Turn it off!"

The robot does as commanded before floating away from the scarred Doctor.

Silence settles into the room.

"I-I think I need to go sit in a corner for a while," he finally murmurs before weakly standing and walking off.

The bot just watches as he goes, a definite sweat drop on his metal cranium.

~XxoOoxX~

A girlish giggle echoes in the extravagant bedroom of her beautiful house. "Oh, stop it, Knuckles…" the albino bat commands playfully as the echidna atop her nips and kisses her neck.

He pulls back with affection in his usually tempered amethyst eyes and retorts, "Would you stop playing hard to get? You're the one who came onto me."

She rolls her eyes and inhales to respond when a ringing interrupts her. She looks at the lavender phone on her nightstand.

"I don't know why you had me install that thing," Knuckles mutters as he gets off of his provocative mate.

"Obviously for moments of emergency." She picks up the incessantly ringing phone and answers with a sultry, "Hello?"

She pauses for a moment, listening to the answer on the end. "Uh-huh… Wait. You say they're doing what now? …oh. I'll be there soon." Her answer brings an incensed "What?" out of the guardian.

Turning to look at him with patient teal eyes, she gets off the bed and fixes her leather attire. "I have to go help out fox boy and his little girlfriend. Turns out hedgehog mating season just hit."

Giving her a raised eyebrow, he demands, "And?"

She huffs at his attitude. "And what? They're kids. They shouldn't be exposed to that for a few years yet. I'll tell Shadow to take Sonic to his place and be done with it."

Knuckles crosses his arms over the white crescent moon that marks his chest. "Fine. Just don't take too long."

She flutters her eyelashes in his direction and leans down in front of him, allowing a lot of cleavage to show. Her lip gloss-covered lips mesh with his sensually before she pulls back and purrs, "Sure thing, Knux."

Knuckles refuses to admit his face is as red as his fur. Then a thought occurs to him. "Wait—little girlfriend!?"

...so I hope you enjoyed? ^^'

Next chapter, surprisingly, doesn't feature much of Sonic and Shadow as we focus on Cosmo and Tails searching for details on the prophecy.
