Unforgivable Sins

Pairing: Vexen/Roxas
Prompt Given: Now
Rated: R
Warnings: Oral, Anal, Pedophilia, sort-of PWP…oh, and Vexen’s in it, which if you ask me should just be one giant warning in and of itself. ;)

Notes: So sorry this has gone so long without an update! -sweatdrops- I got all caught up in this little thing called Life, and I didn’t have as much time to work on this as I wanted. But I’m back now. And I have porn! Yay.

Normally I’m not a big fan of this pairing. Vexen’s a bit too old for Roxy in my opinion. But it’s what the random yaoi pairing generator gave me, so I wrote it.

Farewell


“Is it true? Are you really leaving?”

The man to whom the question had been addressed, a tall, thin, slightly gaunt figure with shoulder-length blond hair, jumped at the sound of a voice in his normally silent basement laboratory. As a result, a flask he’d been holding up to the harsh white ceiling lamps for a closer examination slipped out of his hand, spilling its contents all over the floor.

“Roxas!” The blond man hissed, jumping out of the way as the spilled liquid began to bubble and eat its way through the formerly spotless linoleum floor. “Just what do you think you’re doing? If I’ve told you once, I’ve told you a thousand times not to bother me down here!”

“Sorry,” came the voice again, this time a whisper. A teenage boy, no more than sixteen at the most, walked forward. The artificial lighting glared harshly off his spiked dark blond hair, and his ocean blue eyes were focused apologetically downward at the new hole in the floor. The black cloak, boots, and gloves he wore, identical to the ones worn by the taller blond, made him a stark contrast to the otherwise pristine, clinical surroundings. “I ruined your flask…”

The older man sighed loudly. “It’s all right, I suppose. There are plenty more flasks where those came from, and I haven’t lost anything important. This time,” he made a point of adding, giving the boy a glare through his frosted goggles. “Anyway, what are you down here for? Shouldn’t you be out collecting hearts or something?”

“Yeah…but I had to know for sure if what Axel told me was true first. I’ve been worrying about it all night.” Roxas walked forward, boots clacking loudly on the floor, and hopped up to sit on a bare lab table near the taller blond. “You’ll tell me what’s going on, right, Vexen? Nobody else around here does.”

“Hmph.” Vexen pushed his goggles up onto his head, exposing cold green eyes like a snow-covered pine tree. “Number VIII goes around saying many things. I for one try not to listen to his twaddle. He’d be much better off keeping his impertinent mouth shut.”

“Yeah…” Vexen felt a bit of concern rise in him at how worried the young Keyblade wielder seemed. Roxas still wasn’t looking at him, but was staring morosely at the table, one gloved finger idly tracing around its edge.

“Well, what did Axel tell you then?” The scientist went over to stand next to Roxas, placing his own hands near the boy’s. “Let’s see if I can’t assuage your fears.”

“Axel said you, Lexaeus, Zexion, Larxene, Marluxia, and he were going to some “world between worlds” where the Organization has a second base called Castle Oblivion,” Roxas said, turning his big blue eyes onto Vexen’s gaunt face. “He said he didn’t know how long he’d be gone, either, and that it was going to be a really difficult mission. Is it true, Vexen? Are you leaving? If you and Axel both go away, who am I going to talk to?”

Vexen abruptly turned away, long hair swishing behind him as he busied himself with getting a new flask and pouring different colored chemicals into it. “Axel should not have told you about that,” he muttered. “This is a highly classified mission, and-.”

“And what?!” Roxas leapt off the table, grabbing the taller man’s cloak, so that he was forced to set the flask down and turn to face the boy. “You weren’t going to tell me at all, were you? You were just gonna leave without even saying good-bye!”

Vexen was alarmed to see tears pricking at the corners of the normally stoic Roxas’s eyes. “No…Roxas…” Quite uncharacteristically, he found his own arms winding around the smaller boy’s waist, drawing him close in a hug. “Of course I was going to say good-bye, I just…I didn’t really know how to, I suppose. I’ve never been very good at farewells.”

Roxas snorted into Vexen’s chest. “You’re not good at anything that doesn’t involve science.”

“Such insubordination. I am your elder in this Organization, after all,” Vexen chuckled, one hand moving to absent-mindedly stroke Roxas’s blond spikes.

He thought back to when Roxas had first joined Organization XIII. It had been the end of the boy’s second week at the Castle, and Vexen had been holed up in his lab as usual. All of a sudden the door had creaked open, causing him to jump and summon his giant shield, thinking it was a Heartless. The occasional Shadow sometimes wriggled its way into the basement, but they were dispatched easily enough.

Imagine his shock when he saw not a Heartless, but the newest member of the Organization standing in the doorway, gazing at him with big eyes. Vexen remembered thinking that they were quite an odd shade of blue…such intensity and color was in his gaze…

“What are you doing?” Roxas had asked, pointing to the microscope on the table behind Vexen that he’d been studying DNA through.

At the time Vexen had assumed the boy had only been there to bother him, perhaps as part of some prank Axel had engineered. After all, aside from himself, only Zexion and Lexaeus came down to the labs. So he’d shooed Roxas away, ordering the younger blond to leave him to work in peace.

He’d been quite surprised when Roxas returned the next day, again inquiring as to what Vexen was researching. Again Vexen told him to leave, thinking that this was perhaps the strangest prank any of the neophytes (or Xigbar) had ever pulled. Normally when they wanted to bother him they’d just come down to the lab and break things or steal his pens until they either got bored or he made them leave by force. And they never kept it up repeatedly.

Roxas kept coming back though, and kept asking Vexen questions. Sometimes he’d even bring down some food from the kitchens, which Vexen much appreciated, as his scientific pursuits meant that he ate at a very odd schedule. So he allowed the boy to stay, as long as he was quiet. If Vexen was in a particularly good mood he answered the occasional question Roxas asked as well.

Eventually Vexen came to look forward to Roxas’s daily visits. Despite being an amnesiac, the boy had a keen mind. He actually listened when Vexen explained an experiment to him, remaining quiet and attentive even if the scientist went off on one of his infamous rants. He soaked up information like a sponge, becoming more interested in Vexen’s projects with every new bit of information he learned. The scientist secretly delighted in how Roxas’s face lit up as he was allowed to view things through the microscope or observe the plants growing under artificial light in the lab’s tiny, attached greenhouse. He was going to miss spending time with the smaller blond when he left for Castle Oblivion.

The sound of Roxas laughing abruptly drew Vexen out of his musings, causing him to once again look down at the teenager snuggled close to him. “If I’m so insubordinate, what are you gonna do about it, huh Vexen?” Roxas grinned cheekily up at him. “I mean, I’m probably way stronger than you are. You’re the one holed up down here all the time, while I’m out on missions killing Heartless and getting tougher.” The boy’s grin grew wider, letting Vexen know he was only joking.

What Vexen did next shocked both him and Roxas.

The older man leaned down and kissed the boy firmly on the lips. He watched the big blue eyes widen only an inch away from his face as Roxas’s mouth opened in a gasp. Vexen took advantage of the opportunity to slip his tongue into the younger blond’s mouth, tracing gently over each of the boy’s teeth. As he greedily tasted more of the boy’s sweet flavor-like fresh, cool rainwater-he felt a tightening in his lower regions and knew it would be difficult to stop kissing Roxas now. Still, he intently watched the younger one’s eyes, determined to pull back if Roxas seemed uncomfortable.

Vexen wasn’t disappointed, however, as Roxas soon moaned into his mouth, twining his arms around Vexen’s neck and kissing him back just as hard. The boy’s tongue traced around Vexen’s lips and pushed past his tongue to taste the scientist’s mouth, which was much colder than his own due to the older man’s ability to control ice.

Eventually the two pulled away, breathing hard, cheeks flushed red from what they’d just done. “I…think I wanted to do that for awhile now, Roxas,” Vexen heard himself say, feeling a little twinge of shock at the sudden inner knowledge that his words were true.

“It seems like it,” Roxas murmured, leaning into the taller man’s thin chest and enjoying the feel of Vexen’s arms wrapped around him. “It’s OK, though. I really enjoyed it. Where’d you learn to kiss like that?”

“I’ve lived a long life, boy, both as a Nobody and as a human,” Vexen said. “I picked up a few things along the way. I was also thinking that I didn’t know when I’d get another chance to do something like that, seeing as how I’m leaving-”

“Don’t,” Roxas hissed suddenly, fisting his hands in Vexen’s cloak. “Don’t talk about that. Not now.”

“All right,” Vexen acquiesced, deciding to leave his experiments for now and instead lean comfortably against the lab table, holding Roxas close.

As Roxas and Vexen relaxed in each other’s embraces, however, Roxas felt something hard poking him in the stomach. Shifting slightly to figure out what it was, he smirked up at the scientist upon discovering his arousal straining at black leather pants.

“R-Roxas…erm…” For once, Vexen was at a loss for words.

“Vexen,” Roxas whispered, pulling the older man down by his silver cloak tassels for another kiss. “Take me. Now.”

Vexen broke away from Roxas’s lips, seeming unsure. “You’re so young,” he muttered. “You can’t possibly be sure about this…”

“Vexen.” Another yank of the tassels and Vexen was forced to look Roxas in the eye. Upon being faced with that furious blue gaze, he found himself thinking that perhaps Roxas wasn’t as young and naïve as he came across. “Like you said, we don’t have much time. You have to leave soon, and I’m not waiting until you get back for this. Now take me.”

Vexen gave the younger blond a smirk in return, straightening and pulling Roxas around in front of him. “As you wish.”

Leaning down to once again capture the boy’s sweet pink lips, Vexen gently unzipped Roxas’s cloak, pushing it off the smaller blond’s thin shoulders and allowing it to pool at their feet. Roxas moaned into the scientist’s mouth as thin yet firm hands pushed him gently to the floor, running up and down his sides and across his abdomen.

Vexen carefully removed his own gloves, and gently kissed down his neck and collarbone, stopping at his chest to suckle at a firm pink nipple. He loved the sweet mewls Roxas made as Vexen licked and nipped at the sensitive area, teasing it into a reddened peak before moving on to the next one.

“Vexen…more…” Roxas moaned.

“Not yet. I’ve only just begun, my dear Roxas.” Vexen laughed, thinking of how much fun he would have with the small blond before the day was through.

Moving ever downward, Vexen carefully removed Roxas’s gloves with his teeth so that he could feel the boy’s warm hands against his skin. He grinned as Roxas pushed and tugged at his cloak, guiding the boy’s hand to the zipper. It wasn’t long before Vexen’s own cloak was pooled on the floor next to Roxas’s, his own chest bare.

The scientist continued to kiss and nibble across Roxas’s stomach, stopping when he reached the waistband of the Keyblade wielder’s pants. Looking down at Roxas’s own erection bulging in the fabric of his pants, he whispered, “Well, Roxas? Shall I go farther?”

“Yessss…” Roxas hissed as Vexen unbuttoned his pants and slid them down his legs along with his black boxers. The shorter blond kicked his boots off afterwards, leaving them next to the pants. As Vexen grasped his erection and gave it a few quick pumps, Roxas gasped. “Ah! Vexen, please, I need more!”

“So greedy,” Vexen chided, slowly pumping Roxas’s cock and gathering the precum already glistening at the tip on his thumb.

“Please, Vexen…quit teasing…”

“Then you need to tell me what you want, Roxas.”

“Just…suck…now.”

“Patience.” Still, Vexen leaned down and took the boy’s cock into his mouth, bobbing up and down and soon encompassing the entire organ in delightful coolness. He then began to suck hard, swiping his tongue along the sensitive vein on the underside and tonguing harshly at the head.

“Urgh…Vexen…I’m so close…” Roxas let out a loud whine as Vexen’s mouth abruptly left his throbbing dick. “What the hell?!”

“Now, Roxas, I think it’s only fair that I get some pleasure from this as well.” Vexen gestured to his own erection. “Will you help me?”

Roxas leaned forward and fumbled with the fly on the older man’s pants. With a little help from Vexen, the scientist’s pants were soon on the floor next to his cloak. His boxers and boots followed shortly after.

“Now.” Vexen placed three fingers at Roxas’s mouth. “Your turn to suck.”

Roxas eagerly took Vexen’s fingers in, swirling his tongue around them and coating them with saliva. Vexen moaned softly at the feel of the boy’s tongue, and could only imagine it how much better it would feel working on a much more…sensitive area.

“Enough for now,” the scientist muttered, removing his fingers and reaching around the firm globes of Roxas’s ass. He squeezed once, firmly, and drew out a long moan from the younger boy. Then Vexen teased Roxas’s entrance for a moment before carefully sliding in a finger.

“Aggh! Vexen…”

“Ssh, just relax. It’ll feel better soon…”

“H-hurts…” Roxas moaned.

Vexen leaned down to swallow Roxas’s cries with a kiss, searching for the sensitive spot he knew would make the boy scream. It wasn’t long before Roxas bucked up against him, crying out in pleasure rather than pain. “There! Please, Vexen, more!”

Vexen added a second finger, and a third soon after, pushing against the spot that had Roxas screaming against him, scissoring and stretching the boy’s entrance. “Are you enjoying this?” He murmured next to the boy’s ear, gently licking along its edge.

“Fuck! Yes!”

“May I go further?” Vexen’s own cock throbbed and pulsed harder with every one of Roxas’s moans and screams. He knew he’d end up cumming all over the floor if he didn’t enter the boy soon. And from the looks of Roxas’s own manhood, it didn’t look like he’d last much longer either.

Vexen lifted Roxas’s legs over his shoulders and carefully positioned his cock at the younger blond’s entrance. “Are you sure you’re ready for this? It will hurt at first,” he warned.

“Just do it already. I need it now,” Roxas hissed.

“Very well.” The scientist carefully pushed into Roxas, going in slowly and giving the boy plenty of time to adjust until he was all the way in. “Ah,” he murmured in pure pleasure. “You’re so tight…”

“Vexen…” Roxas muttered through clenched teeth. “Move, dammit!”

Vexen pulled almost all the way out of Roxas’s tight ass and then plunged back in, setting a slow pace out of his worry that he would end up hurting the boy.

“Faster!” Roxas cried.

“Say my name, then,” Vexen said. “Nice and loud, if you please. I want this entire Castle to know who is making you feel like this.”

“VEXEN!”

“Roxas…” Vexen moved faster, going in and out of Roxas until he was at a frenetic pace. He was sure the boy would be sore in the morning, but he didn’t care, he was so far gone, and Roxas was just so damn tight. He didn’t know when he’d get another opportunity to fuck the boy like this, and it’s with another cry of the boy’s name that he released, filling Roxas up with warm cum. It’s this feeling of being filled that sends Roxas over the edge, the boy’s cum splattering across Vexen’s stomach as Roxas cries out in ecstasy.

The two collapsed into each other’s arms on the floor, simply holding each other for several long moments until Roxas sat straight up with a gasp. “My mission! I completely forgot…Vexen I gotta go, Saix’ll kill me…”

“It’s fine. Just relax.” Vexen gently pulled the boy down into a loose embrace and kissed the side of his temple. “I’ll feed him some bullshit later on. Just stay here with me, for now.”

“OK.” Roxas snuggled up against Vexen. “You feel so cold…it’s nice…”

“Thank you.” Vexen smiled, leaning back and closing his eyes.

“Vexen, can I help you pack for Castle Oblivion later? I want to spend as much time with you as I can before you go.” The scientist’s frosty green eyes opened to see Roxas’s blue orbs staring at him, big and sad.

“Try not to worry. I will return as soon as I can, and then we will have plenty of opportunity for more…activities.”

“Kay,” Roxas laid his head back down against the older man. Despite being on the floor, the two soon drifted off into sleep.

Roxas and Vexen never saw each other again.


I’m sorry for the crappy ending. I just couldn’t think of any other way to finish this up.

Embrace the crack! Review!
