Alright… the mystery wasn't why he had passed out – he had already figured it out to be Mukuro's natural odor which always seemed to drug his senses – or why he woke up on a bed. It wasn't even why he could hear Gokudera raving somewhere in the distance, possibly blocked from him by a thick wall or two.

He was rather focused on why he was tied down to the bed, hands and legs spread wide with each limb bound to a poster. And then there was the fact that he was naked, like 'birthday-suit' naked, while spread out like some twisted version of a buffet. Also, what was with the blindfold? His world was in complete darkness!

"Kufufufufu~ finally awake, Tsunayoshi?"

"M-Mukuro! WHAT THE HELL ARE YOU DOING?" He hadn't known the plant liked this sort of thing… Then again, maybe he didn't understand at all? Maybe he had been walking the streets one day, minding his own business, and had unknowingly run into a pervert! Ah, wishful thinking. But he could be a little hopeful, right?

"Oya~ you don't sound happy at all! I'm just doing this because I love you~"

"Hi-hieee?"

Phantom hands drifted over his chest, leather brushing his nipples and whispering down his sides to rub his inner thighs. Tsuna shivered, hands clenching and toes curling. His face flushed red.

"Well, I've been wanting to do naughty things to you for awhile, but by the time I knew about how humans fornicated – " Tsuna mentally died, "I was already gone and making a living for us. And then I was going to show you all that I've learned once I brought you here last night; however, you were heartbroken over your sibling. So I thought I would be patient…" The hands were at his inner knees, stroking the delicate flesh. They rubbed down his calves and then slowly trekked back up. "And then, to finally melt all of my resolve, I wake up alone in the morning… No heart to soothe me, no voice to comfort me… I was completely and utterly alone…" Fingers were groping his ass, squeezing and then releasing, squeezing and then releasing, over and over…

"B-b-b-but… ah… w-what about all of-f this?" Tsuna thought of the bondage and blindness.

"Kufufufu~ all of this? Well, the bonds are to keep you still for my love and the blindfold is to keep you safe."

"S-safe?" Holy shit, he realized with absolute shock, what if his private parts are roots! He tried to remember that first night he had seen Mukuro naked, trying to recall what had been human and what hadn't been. That was the only thing he could think of Mukuro trying to 'save' him from.

"Yes." Lips settled on his, moist and cool, sweetly fragranced and tasting so damn good… "Because whenever you seem to open your eyes, your heart breaks again. Someone is always there to fracture your gaze. So if I keep you like this, you'll never see something heartbreaking and you'll stay happy for me. Kufufufu~ it's a foolproof plan!"

He wasn't sure whether to be perturbed or touched, so he settled for rubbing the side of his face against the bed until the blindfold gave and slid down his cheek. With partial vision, he looked up into Mukuro's disappointed, duo-colored eyes. "I'll be sad if I don't get to see my family – including you. If I'm blind, I can't be sure whether or not everyone around me is happy. And that won't make me happy." Alright, that was a good reason! He hadn't known he had it in him… Now, "a-and can you untie me?"

Mukuro pouted, hands relocating to Tsuna's breast where the rough palms of his gloves compressed against his already aching nipples. "Why?"

"C-cause it's emba-embarrassing! AND WHERE ARE YOU TOUCHING?" Hadn't both hands just been on his chest? So what was with the limb on his manhood, petting his half-hard length? "L-l-lemme go!"

"Nuuuu~ you're too cute, Tsunayoshi… You can't expect me to stop."

"Y-yes I can!"

"Oya~ no, you can't."

"Why not?"

Mukuro pressed his lips to his ear, breathing sickly sweet air against his lobe as he nipped at the cartilage. "Because you can't. I've gone through so many books and naughty movies, trying to figure out how best to please you… Do you honestly want all of my learning to go to waste?"

"I-if this is what it all s-s-sums up t-t-t-o, then YES!"

Another searing kiss, like sugar seeping down the back of his throat and soaking his insides, winding down and into his lower abdomen where it hardened and boiled and then hardened some more. It was molten and it was mind consuming, a tongue slipping smoothly past his lips to twine and tango with his own. Teeth were there, he realized somewhere in the back of his mind, nibbling on his bottom lip and sucking on it.

Too hot… too good… too new. How was he supposed to react? He wasn't sure, so he went limp and numbly followed along, argument forgotten as his body hummed… strangely. Pleasantly, but it felt weird, butterflies warring beneath his skin and lava burning his cheeks. Damn it, he wished he could move! In that moment, he was almost certain he wanted to drag Mukuro closer, let that sweetness of his taste soak into his skin…

When Mukuro pulled away, he whimpered. Hey, he had been enjoying that! And then he wondered, only somewhat because his brain was fried, if maybe it was worth the loss – if only to have Mukuro's mouth on his chest, suckling the hard nubs there, while one hand supported him and the other steadily pumped his member. So much sensation…

"P-p-p-please… l-lemme go…" He tugged forcefully at his restraints, wishing they were just gone.

"Kufufufu~ no. Another time, but not this time."

"B-but this is-ss my f-f-first time!" Was this how he wanted to remember the loss of his virginity? Tied down? … Everything else, he supposed, was okay… Okay considering he hadn't even known he was gay, that his lover wasn't even human and had been introduced to him through his long-dead brother, and that Gokudera was still wailing from outside the house (why didn't he just blow the door open?).

"Kufufufu~ I know~" he kissed a trail down his belly, lapping at his belly button while his thumb rubbed against the head of his penis. "It's my first time too… well, in this lifetime, anyway."

"… R-r-really?"

"Of course. Don't tell me you thought I was going to taint myself by touching the filthy creatures you consider your race. Dirty, dirty things, you humans – twisting and churning the world to your own liking, draining her of life."

"H-h-her?"

"Earth. She's whimpering, you know."

"H-huh?"

"Kufufufu~ as far as you homo sapiens are concerned, I am a plant. We plants have a language of our own, unheard by your little pink ears. We hear through our foliage and roots. And your earth cries, Tsunayoshi, if only you could hear her."

"…" He sucked in a deep breath, trying to calm his raging body. He failed. "I-I can't… And I can't d-do anything about w-what I am… but I don't t-t-think you're just a plant… Y-You're my Mukuro…" The man looked down at him as if the sun rose and fell in his eyes. At last, his hands were still. Tsuna swallowed thickly and released a shaky sigh. "Well, now that the mood is gone, c-can you, uhh, unt-t-tie me?" Though he would have to run to the bathroom… the mood might be killed, but he was about to burst!

"Oya~ you're so funny, Tsunayoshi… I'm not nearly done with you, especially after you say such cutesy things~"

"H-huh?" He bit down on his bottom lip, barely cutting off a cry of pleasure and discomfort as Mukuro's hand began moving again, rough leather coarse against the sensitive skin of his penis, chafing and a bit painful plus just so damn frustrating, so very good…

"You called me yours!"

"GggnnnnaaAH!" He stared with wide eyes up at Mukuro, breath coming in short, harsh gasps.

Mukuro pulled his hand away, leather stained in white, and smirked. "Kufufufu~ was it that good?" He smeared the teen's essence over his fingers, tongue darting over slick lips before sucking the juice off his digits.

The brunette could only watch, mouth dry and mind blank.

With purposeful laziness, he stood up and bit down on the pads of his gloves, sliding one off and then the other, tossing them aside. His jacket was next, pushed off of broad shoulders to fall to the floor in a black pool. His white undershirt disappeared to reveal a sinewy torso. And then, a final act of seduction (that Tsuna would admit wasn't necessary), his leather slacks were unbuttoned and pushed leisurely down his long, strong legs.

He should have known Mukuro went commando.

Mukuro took the tie out of his hair and his indigo mane fell free, completely unhindered and smooth over his shoulders and down his back.

Tsuna's young and hormonal body was on the brink of a second orgasm, never having been subjected to a striptease before.

"I have…" Mukuro purred, stalking back onto the bed, "so many things I want to do with you…"

"L-l-let's not g-g-get ahead of ourselves!" Hiiieeee! He was so screwed… literally!

"We're not. We have all the time in the world to enjoy, why would we get ahead of ourselves? Kufufufu~ you say such silly things." Pop.

For one crystal clear moment, he thought and knew nothing. All he could do was rely on his senses for survival and all they could tell him was that his member was down the man's throat, being nursed and suckled like a treat, Mukuro humming around his penis and tongue doing interesting things that made him want to drown in ecstasy.

"Aaaahh… M-M-Mukuro… Hiieee…" He pulled ferociously at his soft shackles, torso writhing, but he gained no leverage. He remained an entrée for Mukuro's desires, unable to quench any of his own and certainly helpless as his innards created knots of themselves and pulled violently.

A sense of urgency washed over him, so intense he began to shiver – not just outside, but in, all the way down to his heart and soul and the very foundations of who he was began to tremble. "H-h-hurr-rry…"

He sat up, incredible, ethereal male beauty wrapped into one person with carnal wrath written out in his leer. "So impatient already? Now who's getting ahead of whom?"

"Hurryyy!"

"Kufufufu… like a child." Mukuro trailed kisses down from his manhood to his puckered entrance, darting his tongue inquisitively over the quivering ring of muscles.

"D-don't do that! Th-that's dirty!" Tsuna tried to glare at him, but, umm… that meant staring past his bobbing erection to Mukuro's head, meeting his teasing gaze head-on. And that was more than he could handle! With a reluctant moan, his head fell back into the pillow, staring up into the night sky. So strange because the last thing he remembered was Mukuro shoving his coat into his face that morning…

"You, unlike the rest of your kind, are not dirty… absolutely everything about you…" he rubbed his fingers over Tsuna's length, wetting them in precum before dipping one finger carefully into his orifice, grin widening at his keening, "is precious to me." Hands on Tsuna's hips, he pushed his tongue into his canal and sampled for a moment, thrusting shallowly while Tsuna cried out and fought for his freedom.

For far too long – or far too long in Tsuna's opinion – Mukuro molested his hole with his tongue, filling the room with the lewd sound of suckling and Tsuna's moans and whimpers. It was the strangest sensation in his life, Mukuro's muscle inside of him, pleasuring him and paining him at the same time, awkward and yet amazing. It sent thrills up his spine, words tumbling off his tongue that he didn't even understand. "M-M-MUKURO!" And, just like that, he came undone again.

He fell limp on the bed with a shudder, sensitively aware of Mukuro's tongue still in his contracting hole, his inner walls squeezing and pulsing around the man's digit.

"Kufufufu…" he chuckled, pulling out – finally. "You came a lot this time…" He smeared his hands in his essence, creating images in the spurts of white dotting his lithe torso. "I bet I can make you do it again~"

He wasn't going to take that dare. He knew without a doubt that Mukuro could.

His fingers, gelled in Tsuna's fluids, made a beeline back to his entrance. Mukuro even narrated the trek by whistling sharper as he came closer to his destination, as if this was amusing and not a life-altering decision.

"M-Mukuro…?"

A hand wound around his own bound appendage, interweaving fingers as Mukuro's slick digits rubbed against his sphincter. "No matter what book you read or movie you watch, this always hurt the first time around. So just bear with me, hm?" And then he slid a single digit into his entrance, making Tsuna's breath catch. A second finger was too quick to join, making him squirm uncomfortably. His hand squeezed around Mukuro's. The two digits scissored and then withdrew, only to thrust back in as three, and Tsuna bit his bottom lip till it bled.

"Oya~ don't do that, that's wasteful…" Another mind-drugging kiss was given, stealing the pain away faster than Tsuna could remember that there had been pain to begin with. His abused lip was nursed gently and the fingers were moving in and out of him at a snail's pace, letting him adjust.

'Mukuro had my manhood in this mouth awhile ago… and then this tongue was in my ass… so why am I letting him kiss me again?' He did not know and he honestly could not bring himself to care, said tongue roaming the space of his orifice, keeping both mouths far too busy as a final and fourth finger was introduced, just to make sure. He felt so heavy and so full, but not heavy or full enough – a gasp could blow him away and he would never be able to touch ground again, he just knew it. He needed more, he needed Mukuro to hurry, he needed whatever the guy had! "Please!" He wailed into his lover's mouth, chest heaving and body pushing back on the other's hand as assertively as he could while being immobile.

"… Okay~"

The brunette felt, with every nerve-ending in his body, Mukuro's fingers withdraw from him. It was just too tragic and he was desperate to have them back, to not feel so empty all of a sudden…

The hand around his tightened and his lover's voice echoed throughout his hotwired mind, "hold onto me, Tsunayoshi."

He would if he could be untied!

"H-hiieeeee!" His eyes widened with every tenth of an inch that invaded him, just overrun by excruciating pain as the head of Mukuro's cock stretched him to the point where he feared being split in half. "N-no more…" His hand was holding onto his lover so tightly, his knuckles were white. Strain made his lips pale and face crimson, eyes slanted in agony as his toes curled in protest and his body tried to push the invader out. "Stop… Mmmm…"

Those kisses were miracles, he just knew it. He focused his entire self in the embrace of lips, tears gathering in the corner of his eyes but refusing to let them fall. He loved that syrupy, flowery taste; it was a painkiller and Ecstasy, making everything blurry and painless and yet he felt something so overwhelming, he had no will to fight.

While he tried to imprint that taste into his mind, his for whenever he needed to be comforted by the soul-soothing core of his own creation, Mukuro pulls away and grinned merrily down at his pouty expression. "I'm all in~"

"W-WHAT?" His gaze shot between them, unable to believe it. "B-but – how?"

"How else? I slid all of me inside of you and now we really are just one being." Indigo hair fell over them like a curtain, their own private world where Tsuna's astonished gaze met Mukuro's loving smirk. "How does it feel, to be my home?"

"I-it feels…" painful, splitting, hot, too deep, too wide, throbbing… "full. A-and alive…" Was it growing?

"Do you want to know what it feels like to be home?"

No, not really. Because that would mean that he was going to say more perverted things! But Mukuro went on anyway, blissfully ignoring his obvious distress.

"Full. And alive. Kufufufu~ you thought I was going to say something deviant, didn't you? No; all that you feel is what I feel, Tsunayoshi… and it feels… beautifully and mystifyingly aphrodisiacal."

"… P-please… please untie me."

"Aaaww… but I like this, having you completely open for me…"

"Idiot!" Wow, now he kind of felt like Gokudera (when had Tsuna stopped caring that he was still screaming?). Then again, if Yamamoto acted half as bad as Mukuro in bed, maybe Tsuna could understand that…. Not that he wanted to think of his two best friends doing what Mukuro was doing to him at the moment! "J-just listen to me for o-once, okay? I-I want something a-a-and I w-want it from you!"

His lover stared down at him with awe and humor. "Oya~ and that is?"

"I-I…" was he really going to say it? "I want to touch you too! And I can't do that if you have me tied to the bed!" Why did he even have to debate this? Why did he have to fight for his rights over his body? WHAT THE HELL?

Mukuro buried his nose into his hair, breathing contently. "Understood, Tsunayoshi…"

The bonds came undone beneath his ministrations, setting Tsuna's hands free even as his feet were kept captive. He would bring himself to fight over that later. For now, though, he threw his arms around Mukuro's shoulders and dug his nails into his back, inflicting the discomfort he felt on his lover as he waited out the pain shooting up his spine.

"… O-okay… You can… y-y-you know…"

"No~ no, I don't know."

"Liar!"

"You're going to have to be clear with me."

"You c-can move now!"

"Move? Move what?"

"P-please m-m-move your – … your cock…"

"Where?"

"… I hate you…"

"Kufufufu~"

"… I-in me…"

"Oya~ you want me to move my cock inside of you?"

He nodded timidly.

"Why didn't you just say so?"

"M-Mukuroooo!"

"Kufufufu~ okay, okay… I'm moving… feel that? I'm deeper now… Aaah… and feel that? Now I'm sliding out of you… Isn't that mind boggling?"

Yes… oh, yes it was. Shaking and crying out, he tangled his hands into Mukuro's long hair, head in his lover's shoulder as the strangest slivers of delicious friction echoed throughout his frame, electrifying and dangerous. "H-harder…" Because it wasn't fast enough, deep enough – they were a part of each other, but he didn't feel close enough. He had to have more, had to have it quick before he shattered and stopped being just Tsuna anymore.

"As you wish…" Mukuro was looking different too, the brunette realized. He wasn't sweating, but he was definitely changing, something absolutely occurring beneath the skin for him. There was so much fire in his eyes, burning right through him as they stared resolutely into his very soul, demanding everything that he was and leaving nothing behind as he took him over one square inch of skin after another.

And he almost seemed to be… glowing. Not a sunny glow, but a moonlit glow – pale and gorgeous, his soft complexion casting a white shadow around him. He was so gorgeous and he was all Tsuna's.

The teen stroked his hands restlessly up and down Mukuro's back, grabbing anxiously onto his hips as the pace became frenzied and then reaching even lower for better leverage, so far gone he didn't even see Mukuro's crude smirk or hear his sexy remarks. He stared blindly into Mukuro's face, the corner of his eye watching the sky above them. It was obvious, in that moment of watching Mukuro shine and seeing the stars above sparkle, that his lover was not of earth. It appeared almost unfair to keep him there in the world with him…

Just this once, however, couldn't he be selfish?

"M-MUKURO!"

"Tsunayoshi…"

It was the singularly most stunning moment of his life. They both lied there, Mukuro's larger body pressing his into the mattress, and neither seemed to be able to recover fast enough.

In the first moment of clarity that he had, he cast Mukuro a confused look as his lover undid his feet and drooped tiredly in the bed next to him, head on Tsuna's heart. "H-hey, Mukuro… U-u-umm… why did you pull out?" He whispered the question, honestly fearing that someone would be able to hear (OH MY GOD, Gokudera was still calling out for him!).

"Kufufu~" Mukuro drowsily sniggered, already half-asleep. "I'm not a man, Tsunayoshi… if I release my seed inside of you, you will get pregnant… it has nothing to do with gender, it has everything to do with whether or not you can provide the right nutrients…" He was quick to add on before Tsuna could adamantly defend the fact that men could not bear children, no matter his lover's race. "If I were to eject inside of you, hundreds of my buds would grow beneath your skin for two years."

"T-that would be bad for me… wouldn't it?"

"Yes… Yes, it would."

"…" So that was going to be their love life? Hot with a chance of getting pregnant by his alien lover and dying in the process? He didn't really like that thought. And yet, then again, that would take a lot of determination to pull out at the last second, right? Mukuro really did care about him… "Thank you."

His lover offered a small smile and nothing more, already lulled to sleep by the brunette's flustered heart.

Exhausted, sore, and hoping to beat his lover up in the morning for all of it (he shouldn't be so tired for having spent the entire day passed out!), he let himself follow Mukuro into the land of dreams where fairytales were read regularly.

Meanwhile, Gokudera was frustrated… No matter how hard he tried or how many explosives he fired…

The barrier of roots between his Tenth and him never got any thinner. Yet, somehow, noise filtered through only too well. "TEEEENTH! I'LL KILL HIM FOR DEFLOWERING YOU!"

Author's Note: I finally have delivered the smut everyone has wanted! My oh my… how lovely it is! And, no, the story isn't over with yet. I still have a couple more chapters to deliver.
