"The moyashi has to be a prude. You've seen how he gets when Lenalee gets anywhere near touching him."

"I'm tellin' ya, Yuu, it's cuz he's into guys! He doesn't flinch when I touch him."

Kanda scoffed, skepticism clearly showing on his face. He couldn't remember why they had started arguing about this, but now he felt a bet coming on, and he wouldn't be the one to back down.

"You're insane."

"Nah, I'm tellin' you, it's true. I've seen him lookin' at you, y'know. If it were anyone other than Allen, they'd be dead meat, but he's just too cute! Lookin' all embarrassed just cuz he's lookin'. I've even seen him blush, starin' at your ass."

Kanda didn't dignify that nonsense with a response, but he couldn't keep the shock out of his expression. There's no way the moyashi found him attractive. Just no way.

"Yeah? You don't believe me? How about I prove it, then?" And here came the bet. Kanda sighed. "I bet you the two of us can get him all hot and bothered in the next room, just from hearin' us."

"Are you out of your mind? Do you really think I would—"

"Hear me out. I bet we can get him to jerk off while we're goin' at it, or listen at the door at the very least."

Kanda shook his head. Lavi really had lost his marbles if he thought Kanda would do that sort of perverted… Okay, so he was known to be quite active with Lavi when they were alone—he couldn't deny they'd had their fair share of trysts—but this was different.

"I can tell you're thinkin' about it. You might as well get it over with and agree so we can get busy, 'cuz I want you and I know you're feelin' it, too."

"Che." Kanda could be as disdainful as he pleased, but the truth was the truth. He couldn't wait to get into Lavi's pants after the two and a half weeks they'd just spent away on separate missions. "Fine. I accept."

"Yes! Okay, so Allen usually bathes after dinner, so we can do it in the bathhouse then. Besides, that's the least busy time for the Order cuz everyone's going to bed after a long day's work." Kanda didn't bother asking how a Bookman knew what he did. He'd learned by now to accept the odd bits of knowledge Lavi accumulated for no apparent reason.

"What do you suggest for the terms?"

"Glad you asked, my man, glad you asked," Lavi winked. "If I win, and Allen shows obvious interest, you have to admit I was right," Kanda sneered at that, "And you have to do whatever sexual favors I ask for a week!" Kanda blanched. Lavi would undoubtedly ask him to give oral sex. He hated doing that, even though he liked the sounds Lavi made. Well, knowing Lavi, he would return the favor without even being asked, so that was a plus.

"Fine. And if I win, and the moyashi is completely disgusted and leaves, you have to concede my victory and shut the hell up whenever I tell you to for two weeks." He ignored Lavi's mock-hurt face and glared until he got his answer.

"Deal."

Allen had just eaten half his weight in Jerry's delicious cooking and was cheerily whistling as he walked to the baths. He'd sparred with Krory before then, so he was feeling pretty grody, in that satisfying, hard-work kind of way. He took a quick shower before sinking into the hot water of the Order's man-made onsen, but he was only there for a few minutes before his relaxation was interrupted.

Hearing the doors open and shut from the next room, Allen looked up to see who would come in this late. His eyes widened.

"Lavi? Kanda?"

"Hey, Allen. How's it goin'?" Lavi grinned at Allen and proceeded to drag an annoyed Kanda into one of the shower stalls.

Allen didn't know what to do. His two guy friends had just gone into the same shower stall together. As if it was perfectly natural to do so. Allen never paid any attention to relationships among his friends, but two guys…and the perpetually-scowling Kanda being one of them…

"C'mon, Yuu, you're not gonna back out now, are ya?" Allen barely heard Lavi teasing Kanda over the spray of the shower they were in.

"Che."

"Now that's more like it," came Lavi's lusty reply to whatever Kanda had done.

Wait. Lusty? There was no way they were doing what Allen thought they were doing. Was there? He had to know. Allen slid out of the water nearly soundlessly, wrapping his towel around his waist and sneaking over to their stall. There was a gap between the shower door and the wall. Allen looked down, utterly torn about what to do. On one hand, he really shouldn't be doing this. He was no peeping tom! On the other hand…he really wanted to know what they were doing in there.

It took him all of 10 seconds before he leaned forward to peak into the stall. What he saw nearly made him choke on his own gasp, turning beet-red and covering his mouth with his hand.

They were both bare to the waist and getting bare-er. Lavi freed Kanda's hair from its tie as Kanda unbuttoned and pushed Lavi's pants down his hips. Lavi kicked his shoes and pants off, holding onto Kanda's hips for balance. He kissed Kanda, who pulled his bandana off and kissed him right back. He let Lavi unzip his pants, and Allen had to stop watching because Kanda wasn't wearing any underwear, unlike Lavi.

Allen stepped back from the stall, eyes wide and face burning. I just saw…Kanda's…and Lavi was nearly naked…and they were making out…oh God.

Allen walked—half-ran, really—back over to the onsen, telling himself he was going to ignore them and go along with his bath like normal, lest they get suspicious when they came out and he wasn't there. But they had to know he could hear them, right? Standing on the rim of the pool, he stared at nothing as he tried to slow his frantic heartbeat. This isn't happening. It isn't and I'm not going back over there. I'm not.

"This is stupid," Kanda breathed.

"Yeah, but it's still fun." Lavi's voice was just as low and sexy as his had become. Kanda always loved that about the redhead. No matter how stupid he could be most of the time, when they were alone, he was serious, and sexy as hell. It was like he turned into a completely different person with him. That idiotic, grinning loudmouth became his calm, intelligent, boyfriend, and he wouldn't have it any other way.

Kanda bit that plump, bottom lip and traced his fingers down Lavi's hips, pushing the fabric of Lavi's boxers down as he went. Lavi groaned as Kanda's teeth grazed over his lip, skin shivering at the cool touch on his waist. There was nothing he loved doing more than Kanda, and he said so as soon as he had his lip back.

"Shut up, idiot." Kanda stepped under the hot water, now that he was naked, and pulled Lavi under with him, finding Lavi's tongue with his as soon as he was close enough. The two kissed and stroked each other's wet skin for a while before Lavi remembered what they were trying to do.

"We've gotta be loud, Yuu. Else Moyashi won't hear."

"Hn." I'll give you something to be loud about, then.

"Aah!" Lavi tilted his head back to give Kanda more room to bite and kiss his neck. "Mnn, yeah. That's good, Yuu."

Lavi tweaked Kanda's nipples and traced over his ribs, Kanda's one ticklish spot. Kanda was only ever a vocal lover if he teased his favorite spots in just the right order. And then he became a crazy, feral beast, growling and biting and taking control. Lavi was fine with being dominant or submissive, but he always got off on Kanda's wild side.

Kanda bit hard enough to leave a mark and Lavi whimpered. He pushed him back against the tiled wall. "Aah. It's cold."

"Deal with it." Kanda dropped to one knee and Lavi quickly nodded. Kanda almost never sucked him off, complaining that it was too troublesome and not arousing enough. He had been known to surprise Lavi, though. Apparently this was one of those times.

Lavi didn't bother stifling his moans. His head plunked against the tiles and he would probably get a bruise, but at the moment, all he could feel was Kanda's hot mouth on him. Lavi realized this was probably the single best way to get him to his absolute noisiest, and he smirked to think Kanda was serious about this bet. Then it was gone, forgotten as Kanda deep-throated him just the way he liked it.

"Ah! Yuu!" he panted, "Nn, it's so good…" Kanda reached up to twist a wet finger into Lavi, searching around for the spot that would really make him moan. Kanda found it and Lavi screamed, jumping in his mouth and thrusting forward a bit. He held Lavi's hips against the wall with his free hand and continued tormenting him, appreciating the loud groans, ragged panting, and desperate whimpers coming from him. If the moyashi was still here, he had to be either crazy or deaf.

0o0o0o0o0o0

Allen heard Lavi shout and immediately wanted to rush back over. He only held his ground by force of will. It sounds like Kanda's killing him in there. Maybe I should go help—No! I can't. But…maybe just a quick peak? He cautiously tip-toed over and glanced in. He almost immediately acquired two obvious reactions to the scene, one of which being a brighter version of the blush he hadn't quite managed to get rid of. The other…well, Allen wasn't really familiar with the goings-on of sex, but he knew what a hard-on was.

He couldn't believe what he was seeing, who he was seeing. It made him wonder what it would feel like to be in Lavi's place, or even Kanda's. By now, Allen's natural curiosity was starting to get the better of him. The fact that he was still watching was evidence enough of that. He placed one hand on the door and the other on the wall, leaning in closer to get a better look.

"Yuuuu" he moaned, "Nngh. Y-you have to stop, Yuu." His fingers threaded in Kanda's hair and holding him close said a different thing. "Aah. You have to stop…I'm so close…"

Allen watched Lavi's face alternate from relaxed pleasure to painful-looking concentration. Kanda tortured Lavi for a moment longer before pulling back, leaving a small hickey on the sexy dip bordering 

hip and abs. Lavi pulled him up into a sloppy kiss and Allen licked his own dry lips when he glimpsed the deep pink slide of their tongues against each other. Then he looked down, following Kanda's hand disappearing between them, and almost groaned.

"Uunh! Yuu, please, please stop…just for a minute," Lavi panted, holding onto Kanda's shoulders for stability. Even Allen could tell he was trying hard to hold back; he could practically see Kanda's smug smirk. It was unbelievably erotic, and without thinking, Allen surreptitiously slipped a hand down to rub some of the building pressure away. The touch caused a surprisingly strong jolt and a sharp gasp. Allen's eyes widened and he turned to run, knowing they'd been able to hear him, but before he could get out of sight, Lavi cracked open the stall door and caught him in the act.

"Why, if it isn't little Allen." Lavi's tone was playful and breathy, not a hint of anger, annoyance, or even surprise. Allen looked back over his shoulder from the eight or so feet he'd managed to flee, and felt his jaw drop at Lavi's lecherous grin. "Curiostiy killed the cat, y'know. Wait just a minute, Moyashi, where ya runnin' off to?"

He had taken another step towards the door but stopped again, as prompted. His eyes found a drop sliding from Lavi's drenched hair down his neck, over his collar bone, and followed its path until it soaked into his towel, helpless to look away. Lavi was surprised but flattered to observe this and he smirked when he realized why Allen wasn't turning around.

Kanda frowned as Lavi got that look on his face. That, "oh, you are so caught in my trap," look. Lavi at least had the decency to grab his towel and cover himself before sauntering over to the terrified Brit. Kanda could see Allen's blush from where he remained. Well, it looked like it was Lavi's win, this time.

"Hey, Allen, it's all good. We get it, right, Yuu?" Lavi and Allen looked back to see Kanda's scowl deepen disdainfully, but he didn't deny it.

Allen looked hopefully up at Lavi but still refused to turn around. Lavi gave him a reassuring smile before turning to Kanda and saying something in a language Allen didn't understand. He thought he might have heard his Master use it once in a while. Whatever he said must have been scandalous, if Kanda's expression was anything to go by. The two exchanged a few phrases, Lavi placating and Kanda outraged, until Lavi said something in what Allen recognized as a lascivious tone, and Kanda actually blushed.

"So it's settled, then, yeah?" Lavi waited for Kanda's reluctant nod before turning that sly grin back on Allen, who had turned to his side to watch the exchange. He followed Lavi's line of sight to the lingering evidence under his towel and immediately turned to get the hell out of there. Lavi stopped him with a hand around his wrist.

"What are you doing?" Allen was slightly terrified.

"Weeell I thought, maybe, if you're interested, you would want to play with Yuu and me?"

Aaaaand Allen lost his brain. Lavi chuckled at his nonplussed expression and pulled him closer. Poor Allen's mind was a dizzy blank as Lavi reeled him in and planted a kiss on his cheek. He gasped and regained his sanity all at once, his face tingling where Lavi's lips had touched.

Allen blinked at Lavi and remembered to breathe. How many times had he secretly stared at these two, wondering why he liked looking at them when there were beautiful girls all over the place? How many times had he caught himself daydreaming about them with fewer clothes than they usually wore? How many nights had he woken up sweaty and disheveled, with an odd ache in a very unusual place? He'd played it off as admiration for his elder exorcist comrades, but who was he fooling?

"Oh my god." Allen swallowed and shook his head. Was he really going to do this? Yeah, he really, really, wanted to, but…wasn't it wrong or something? But if Lavi and Kanda could do it, why couldn't he? He let out a shaky breath, staring at the floor, and gave a tiny nod.

"Awesome," Lavi muttered.

"Wha—?" He was going to ask how this sort of thing went about, but Lavi had taken that moment to cut him off and give him his first real kiss. When he could think with actual words again, Allen noticed Lavi wasn't using his tongue like he had with Kanda. He was mostly just using his lips and occasionally flicking his tongue out to play with Allen's shy mouth. Allen loosened up and mimicked Lavi's technique, instantly noticing an increase in feeling.

Kanda watched his boyfriend teach the moyashi how to kiss from the shower stall he had yet to leave, and no, he was not enjoying the sight, thank you very much.

"How do ya like it, Allen?" Lavi asked when they broke for air.

"Mmm…" He was still a bit dazed.

"Yuu's kisses are completely different from mine. Wanna try it?"

Allen's mouth parted uncertainly. He didn't want to say yes and get gutted, strangled, or drowned in the onsen, but yeah, he wanted to "try it."

Kanda could see the indecision and slight fear plainly on his face. He gave an annoyed huff and stalked over, still nude and dripping wet but not appearing to care. Holding the back of Allen's head, Kanda gave him his version of a kiss. This mostly consisted of lots of tongue, a little teeth, and a melee of pleasure resulting from both. Allen's eyes slipped shut on contact. Kanda was warmer than Lavi, fiercer, hungrier, and he could definitely tell that, where there had been genuine affection in Lavi's actions, there was mostly lust in Kanda's. And he didn't mind one bit.

When Kanda relinquished his hold, Allen stepped back, gasping, and Lavi held his shoulder so he wouldn't fall. Lavi clearly remembered his first kiss with Kanda. He'd fallen onto the bed in a horny, breathless heap by the time Kanda had let him go. In fact, that little event had resulted from a bet between them. Kanda won that one.

"Allen." Lavi's lusty stare made his blood pound even harder. "Do you trust us?"

"…What do you mean?"

"Trust that we would never hurt you, and let us show you how good another person can make you feel."

"…Yeah…I trust you." Lavi smiled and pulled Allen back towards the shower stall.

Kanda followed the two and locked the door behind them. Honestly, he wasn't too sure about this. Lavi had convinced him with that annoying, 100 success rate method he had when it came to getting something he really wanted. He'd asked Kanda if he thought Allen was hot, did he mind fooling around with him, and wouldn't he get jealous if Lavi did it without him. Yes, no, and yes, respectively, but all he'd told Lavi, after deciding to agree, was that he was going to kill him later and he'd better make it up to him. Then Lavi had promised whatever kink Kanda pleased, including "that," if he still wanted to try it. Kanda hadn't been able to keep the blood from rushing up at that.

So here he was, about to molest Allen Walker in a shower with Lavi. Speaking of, the two were currently necking under the hot spray. Both had lost their towels at some point. Apparently Allen wasn't body shy when it came to Lavi.

Kanda abruptly realized he was shivering from the cold air on his wet skin. Annoyed about this, he pushed the two out of his way and warmed up in the water for a bit.

Lavi saw this as Kanda's usual way of saying he wanted to be included without actually saying anything. Allen looked uncertain again, thinking he'd been given the cold shoulder. Lavi winked at him and stepped behind Kanda, tracing a finger from one shoulder to the other, draping the soaked silk of his hair over his tattoo. He leaned in close and murmured something in Kanda's ear, then licked and nibbled said ear without a hint of complaint from Kanda.

Allen's eyes darkened a shade to hear Kanda's soft groan, see Lavi making Kanda turn a faint pink all over his body, and watch his hand glide over Kanda's stomach to tickle his navel. Allen swallowed and tentatively reached a hand out. Kanda's eyes were closed, off his guard, so if he had any chance of touching him without an evil glare or imminent pain, this was it. He took a deep breath and traced a finger along the curve of his neck, around a nipple, and down to his hip. Kanda looked at him as if he only just remembered he was there, but he didn't punch him, so Allen gripped Kanda's hip and took a step closer, gently kissing down the line his finger had just followed.

Kanda allowed the contact, even went so far as to grab the back of Allen's neck and pull him into another kiss. Allen heartily reciprocated. Lavi took his mouth from Kanda's ear long enough to see the new development and think of an evil way to make both of them even hotter. He used the hand that wasn't teasing just above Kanda's erection and placed it on the small of Allen's back, then immediately pressed the three of them tightly together.

Allen and Kanda gasped almost simultaneously from the touch of their bodies against one another. Allen went red and, with a shuddering exhale, looked up into Kanda's eyes. He witnessed the full force of the lust in those sharp grey eyes, and it took his breath away.

The next thing he knew, his life was being sucked out through his mouth, or so it felt. Apparently the kisses Kanda had been giving weren't even on the level of his most passionate. All Allen could do was try to keep the pace, and his desperate sounds to a minimum. When Lavi's hands started roaming his back, he had to step back for a break.

"I think we're goin' a little too fast for 'im, Yuu. Maybe we should slow down?" Kanda just smirked, wrapping an arm around Lavi's neck and turning their heads to make out with him for a moment.

When Allen had caught his breath, he watched the other two, not quite knowing what to do again. Without their touches to distract him, Allen became aware of his arousal, almost urgent in its need to be acknowledged. He watched the spectacle before him, feeling his cheeks heat with something much hotter than a normal blush, and realized his hand had been snaking its way down his side, across his belly, and over his hip.

Hell with it, he thought, and ghosted his fingers over himself. The more he saw and felt, the more his inhibitions melted away like fresh ice in the desert of rapture. Soon he was tilting his head back and biting his lip, leaning against the wall to support his weakening body.

Right on the edge, his wrists were suddenly trapped beside his head, a harsh grip and an even harsher nip to his neck. He made an involuntary whimpering sound in his throat, and Kanda's growl rumbled into his skin.

"What did you think you were doing, having all the fun by yourself? That isn't how this works." Kanda's reproach was met with a small nod.

With a soft chuckle, Lavi kneeled on the shower floor and pulled Allen down to sit in front of him, directly under the warm splattering of the shower. Allen was hypnotized by the smoldering eye locked on his, letting Lavi push him to lie down and lean over him on all fours.

Lavi licked a nipple, then its twin, and swirled his tongue around Allen's cute little navel on his way to what he really wanted to taste.

Kanda enjoyed the sight of crystalline droplets coating his lovers' skin, leaned against the wall with his arms crossed over his chest. He saw Allen's shocked pleasure as Lavi acquainted his mouth with Allen's erection and he felt a responding flicker in his stomach.

"So, Walker, just how far will you go?" Kanda stepped forward and kneeled above Allen, looking down into his shifting expression. "Stop at the surface or dive right in?"

"Wha—ah, Lavi!" Allen focused on Kanda as well as he could, but he'd never felt anything so wonderful and he knew he couldn't take much more. "What do yo—ngh—what do you mean, K-Kanda?"

"I mean, do you want one of us to fuck you or not?" Kanda leaned a little closer, fixing his stare onto Allen's wayward gaze.

Well, put that bluntly, Allen could comprehend, even with the distraction of almost all of his nerves telling him he was experiencing bliss. Yet when he tried to think about the question, Lavi started humming around him and he lost his vision to blindingly bright stars for a moment.

Lavi decided it was time to put the little moyashi out of his elated misery. He employed all of Yuu's favorite tricks—the ones that made him gasp and shudder so deliciously—on Allen. Eye trained on Allen's pinched face, he swiftly brought him past the gates of pleasure, over the shocking burst of sensation, and into the tingling warmth of fulfillment.

Allen's spine arched with a snap and his legs came up to press against Lavi's sodden hair. Kanda leaned forward and caught the long moan leaving his parted lips. The unexpected thrill of an upside-down kiss mixed with his orgasm left Allen reeling.

"Fuck, Allen. You just had the sexiest orgasm I've ever seen." Lavi kissed back up to his neck, where he promptly left a nice red mark.

If Allen weren't so far gone by now, he would have blushed at Lavi's words. Rather than embarrassed, he felt a bone-deep contentment, wrapping his arms around Lavi's neck and tilting his head to give him easier access.

"I think he's all tired out now, Yuu. We might have to finish without 'im." As he spoke, he could feel Lavi pressed against his hip, still hard and insistent.

"Mm-mn," he shook his head. "'M fine. Just need a minute…"

"So you're good for another run, then? Excellent."

"Then answer the question, Walker," Kanda breathed into his ear.

"Question?" Allen shivered. "Oh! Um…"

"It won't hurt, Allen. Yuu's good at makin' it feel real good," Lavi hinted.

"Kanda? Kanda!?"

"Yes, me. Got a problem with it?"

"W-well…" Allen blushed.

Kanda smirked. "So it's settled."

"I'll get the lube," Lavi cheerfully volunteered.

"And I'm sure you'll be a good little moyashi and suck him off while I fuck you."

"What!?"

"Got it" Lavi returned and handed the bottle over to Kanda, who then maneuvered himself between Allen's pliant legs.

Before he had a chance to even attempt an objection, Kanda's soft fingers were brushing against a very sensitive area and he simultaneously blushed and gasped. Lavi leaned down to kiss him while Kanda worked, both of their hair and the water still spraying them tickling his oversensitive skin. Kanda's lips and tongue danced and teased over him to distract from the strangeness of what he was doing with his fingers.

And distract it did. By the time Kanda's skillful fingers deemed their work done, Allen was a whimpering mess between the two of them. Even though it would be uncomfortable, Kanda knew he wouldn't last long, and neither would the moyashi, so he nudged him to his hands and knees. He saw Lavi give a reassuring smile and felt some of the tension leave Allen, where he held him by the hips.

"Ooh! I got an idea," Lavi exclaimed. He then proceeded to shimmy between Allen's arms and grab his waist to steady him a bit more. "You don't have to, y'know, reciprocate, if ya don' wanna. I jus' want another taste," he said, and took Allen between his lips at the same time Kanda began to press into him.

Allen cried out at the dual stimulus to his—previously untouched—teenage body. All he could do was breathe and try to stay relaxed until he could feel Kanda's hips against him. Lavi was an enormous help, of course, so much so that Allen decided to overcome his uncertainty and try to return the favor. He looked down, the waiting arousal daunting and alluring at the same time. Suppressing his moans and focusing his attention, he gave a tentative lick.

A short, surprised groan shook through Allen from Lavi, leaving him gasping for the air he'd somehow lost in an instant. He liked it, but it was almost too much. Kanda had begun a steady rhythm and Allen found he rather liked it, especially when he could focus on giving Lavi pleasure as well.

Slow and awkward at first, Allen gradually found what Lavi loved and what he didn't, and recognized an unusual pride in Lavi's desperate sounds and the haphazard thrusts he couldn't quite control. Kanda's pace quickened, the angle changed, and Allen couldn't breathe for a shocking moment. It was so good! He knew Lavi appreciated Kanda's pace as well: Allen's moans were deep and nearly constant now.

"Allen! I'm gonna come…" Lavi warned. Rather than slow or stop, Allen sucked with surprising vigor. Lavi yelled as he came, and Kanda groaned at the sound that always sent tremors through him.

Distracted as he was, and delighted in bringing Lavi to orgasm, Allen never even registered the taste, but the strange warmth just added to everything. Lavi resumed his job just as soon as he regained the strength in his muscles, and Allen hummed appreciatively.

Kanda's sweat dropped and mixed with the water on Allen's back. Any moment now. He grit his teeth and focused on the feeling, welcoming the approaching end. His fingers gripped soft flesh hard enough to bruise and he leaned over to sink his teeth into Allen's unsuspecting shoulder.

He felt the same liquid heat he'd just swallowed and the twinge of pain beside his neck under the overwhelming power of his second orgasm and Lavi's extraordinary mouth. It was far too much for his first time, and Allen just couldn't take it. With a weak groan, he collapsed beside Lavi, falling into an instant sleep that scared Lavi and praised Kanda.

"Shit, Yuu, you didn't hafta fuck 'im into a coma!"

"Hn."

"Seriously, though…"

"He'll be fine," Kanda smirked, ego expanding by the second.

They looked down at the docile exorcist and knew this wouldn't be the last time they included him in their fun. He was just too cute!
