Growing Pains

Author's Notes: This has nothing to do with my other fic. All that there is in here is some good ol' yaoi featuring everyone's fav couple Laven! The idea for this just popped into my head so randomly and I can't get it out. So I decided to share it with everyone! :D
-----------------------------------------------------------------------------------------

Everything was going great so far, perfect in fact. When Lavi went to check on Allen he found him already hot and ready. Apparently missions that last for several weeks can have a damaging affect on a teenage boy's libido. Not that Lavi could blame him-being separated from Allen for so long was hard-but Allen was suffering worse.

Allen actually spread his legs open when he saw Lavi at his door. Lavi could hardly even get on the bed before Allen pulled the red head in. The younger Exorcist his lover's lips in a mind glowingly passionate kiss. Lavi's eye rolled backwards as Allen's tongue danced frantically inside his mouth. When Lavi broke the kiss, mostly for air, the two teens quickly got into it.

Despite all the protests from Allen, Lavi went ahead with the foreplay but quickly found his pace when the moment arrived. Of course Lavi always enjoyed Allen's tries to resist him, however this new slutty Allen was just as much fun. The sounds he was making just made Lavi even harder. Everything was great, except for Allen's latest mewl.

Allen's usual cries of pleasure sounded more like a deathening scream of pain. His face even twisted, folding in on itself as Allen writhed. All of this seriously confused Lavi, who stopped all actions, and could only look down at the white haired boy in near-terror.

"Yo-you okay, Allen? 'Cause that last moan of yours didn't sound all too pleasurable."

Lavi sat on his legs while his hands held Allen's leg up in the air. Allen, who laid on his back while fisting his bed sheets, looked up at the red head through lidded eye as he spoke:

"No, I mean, I, hah, I, I think I'm just sore,"

"Sore? How?! You're perfectly tight! You haven't been cheating on me have you? Has being away from me for so long been so hard on you that you needed a surrogate?!" Lavi dropped Allen's legs and leaned drastically forward. His hands on either side of Allen's head Lavi's face was a hair's distance away as he interrogated the youth.

Allen screamed again when Lavi push forward. Lavi's cock was still hilt deep inside of Allen's ass and the sudden movement bruised him further.

"Agghh! Pull out!" Allen's face contorted again.

"Seriously?" Lavi was almost skeptical.

"It HURTS!!" Allen was fuming from all the pain he was in. "And you sound just like Komui, just so you know." Allen added as Lavi slid out of him.

"Uhh, okay, ouch." Lavi replied sardonically as he leaned back to sit on the bed. "So, why are you so sore already? Did we rush it too much?"

"I dunno," Allen shrugged. "But you just felt so big and-"

"Well, I would hope so." Lavi interrupted with a hint of pride in his voice. Allen shot him a look before continuing.

"No, I mean you were so big it *hurt*." Allen heavily emphasized the last word he spoke.

"We were going at it a lot before you left for the mission. And think about it; the first time we did it you couldn't even stand without me holding you up. Maybe you just got so stretched for a time and shrunk back during the mission. That is if you weren't cheating on me."

"I swear you need to stay away from Komui."

"And I swear I'll slam into just out of spite if you say that again."

"Maybe we're over thinking this."

"How so?"

"It could just be as simple as you're growing." Lavi looked like a total idiot when Allen said those words. Disgruntled, he continued, "Look, you're a Bookman, right?" Lavi nodded. "Don't you know that guys don't stop growing until they're twenty? And you're still only eighteen so,"

"So, you're saying that I've still got room to grow?" Allen swallowed hard when he saw the almost hungry look in Lavi's eye. "No wonder you felt so damn tight. It was almost too good to be true."

"Uhh, Lavi, you're starting to scare me." Allen had his back pressed against the head board of his bed. If only he could get further away from the red head. Seeing Lavi's cock twitch with anticipation only made things worse for Allen.

"Don't worry, Allen. I'll make sure to properly stretch you this time." Lavi was smiling sweetly but the glint in his one working eye was almost psychotic.

Allen yelped as Lavi grabbed his ankles and pulled him down the bed. Lavi stopped when Allen's head was on the pillow then he threw his legs over his shoulders. With another sickeningly sweet smile Lavi probed the youth's entrance making him jump.

"Damn," Lavi hissed. "You're seriously tight but that's mostly from swelling, right?" He could feel just how tender Allen's muscles as he rubbed his insides. Allen moaned lowly as Lavi worked him. "And for the next stage," Allen let out another loud yelp as Lavi slid a second finger inside of him. His hips began to buck from the scissoring action the fingers made. "You enjoying this?" Lavi asked playfully.

"Shut up," Allen tried to glare at him but clearly failed seeing how Lavi only laughed.

"We need to get you stretched so we don't hurt you again." Lavi explained as he tenderly kissed Allen on the forehead.

Allen continued to moan and buck as Lavi's fingers continued worked his insides. His voice got even louder when the third digit was added. Lavi's fingers slid up and down Allen's rectum, stretching him to new limits. At one point Lavi's fingers brushed against Allen's already sensitive prostate. That made his hips jump greatly and almost knocked the wind out of him. Allen thought about killing Lavi for doing all of this to him.

"And here's the money maker." Lavi announced in a sing-song voice as a fourth finger joined the rest deep inside of Allen.

Allen almost screamed as the four fingers spread him open. Lavi's finger twirled inside of him continuing to stretch his muscles further and further. The pain wasn't so much from the stretching as the actual lack of Lavi's cock filling him up. His muscles automatically clamped down around the digits wanting to feel full. This just made Lavi's job all that much harder but he didn't mind.

He thoroughly enjoyed watching Allen squirm under him. Lavi mused to himself how Allen's cock twitched and jumped about like it would explode at any minute. Not that Lavi wasn't having the same problem. His own member wept from the absence of Allen's tight ass but he couldn't have any fun later if Allen was in so much pain.

When he was satisfied he whispered into Allen's ear:

"Are you ready for this?" Allen nodded as he gulped. "Okay then," Lavi spread his fingers to form a ring that opened Allen up to him. Slowly and carefully Lavi slid his cock into the opening that his fingers made. Allen was still squirming under him, his hips bucking, and even his whole body would jump from time to time. Lavi could've gone in faster but he wanted to be sure this time.

Allen decided that he really was going to kill Lavi this time. He could've handles the four fingers but to add those with Lavi's growing cock was way too much. And Lavi had to know it too. Lavi was probably doing all of this just to tease him was Allen's guess. His cock slowly made its way straight through until the tip brushed up against his sweet spot. That just made Allen struggle even more.

Allen breathed a sigh of relief when Lavi removed his fingers but that feeling soon faded when Lavi whispered into his ear again.

"And now for the fun part."

Lavi slid out Allen until only the head of his cock rested just beyond Allen's entrance. With a little more speed Lavi moved back inside of Allen making sure to avoid hitting the youth's prostrate. He kept up this pattern for some time. Gaining speed with every turn Lavi quickly found his pace again. He found encouragement from Allen's moaning. The white haired Exorcist's breathing was becoming more shallow and ragged as Lavi continued.

When Lavi was comfortable with his speed he slammed into Allen hilt deep, bruising the boy. Lavi was rewarded with a loud and shameless moan that was dripping with unbridled pleasure. It made him shiver, he could feel his own lust rise to a new height.

Well now I know the best way to get Allen fired up, he thought to himself.

The two young Exorcists went through several more rounds until they had climaxed. Each time Lavi struck Allen's sweet spot he would let out a new and exciting moan that further encouraged the red head. Lavi kept finding the strength to thrust into Allen with increasing force every time making Allen moan more still.

Lavi ended the cycle when he pulled out of Allen for the final time. Not moving quickly enough some of his seed was expelled while still inside of Allen. But most of it landed on Allen's stomach and Allen's spilled out onto Lavi's chest. Lavi couldn't help but grimace knowing that Allen would be pissed about that.

Lavi collapsed onto the bed completely spent. He landed right next to Allen and tried to snuggle his younger, but Allen wasn’t having it. Allen rolled onto his side facing away from Lavi as he covered himself with the bed sheets.

“Hey, Allen, what’s with the cold shoulder?” Lavi pulled on the sheets hard enough to force Allen to rollover but he still kept silent. “You still mad at me?” He asked as he uncovered Allen’s face.

“Of course I am you idiot! It HURT!!” Allen screamed directly into Lavi’s face.

“Oh, c’mon. It wasn’t that bad.”

“Yes it was!”

“Oh.” Lavi blinked. “Well, I didn’t think so.” Lavi laughed it off. Allen wasn’t amused. “Here, at least let me clean you up.” Lavi pulled at the sheets exposing Allen’s cum encrusted belly.

“No! You’re untrustworthy!” Allen fought to recover himself but quickly lost.

“Why don’t you be a good sport, Allen?” Lavi hovered over Allen as he pinned the youth’s wrists down. Even though Lavi was smiling playfully, Allen simply glared up at the red head. Lavi was taken back. “Uhh, did it really hurt that bad?”

“YES!!”

“Seriously?”

“How many times do I have to tell you?!”

“I’m sorry, I’m sorry. It’s just, haahh,” Lavi sighed heavily as he let himself fall back onto the bed. This time Allen turned to face him. “You *were* enjoying yourself back there. So I didn’t take any of it seriously I guess. But I’m really sorry if it hurt you that bad.” Lavi ended with a gentle kiss that Allen returned.

“It’s okay. I’m sure I’ll be fine soon enough. Just be more careful next time, okay?”

“I will. I promise.” Lavi said as he brought the silver youth close to him. Allen leaned in and snuggled his lover. “Hey, Allen,” Lavi whispered into his ear.

“Wha’?” Allen answered already nodding off.

“I love you.”

“I love you too, Lavi.”
