Worked Up So Sexual

Hey sup. Uh...I was looking through all these stories in the Zim section and I was annoyed that so many of them have Dib uke. Zim seems much more uke to me! So I wrote a lemon with Zim uke. I almost never write stuff like this so...yeah. It's just me having a fanwank.

Almost forgot! I say stuff about Zim's genitals in this, but obviously I dunno if it's true. Just made it up, so don't be all like "omg how do you know??"

----

"Computer! Computer!" Zim shrieked, struggling against the wires that bound his wrists and ankles. "Let go of me right now! Obey your master!"

"That won't work now, Zim." Dib smirked, looming over the alien. "It wasn't easy, but i figured out how to control your little computer. It follows my orders now."

"Impossible..." Zim stared at Dim in horror, then began struggling again with renewed intensity. "Gir! Gir, come here!"

"I took care of that as well." The look on Dib's face was positively evil. Today, it was his turn to gloat. "This is just perfect. I thought it would be a nice touch to take you apart in your own base, don't you think?"

Zim opened his mouth to say something, anything to deter Dib, but no sound came out. The hopelessness of the situation hit him, and it must have showed in his eyes because Dib's lip curled with satisfaction. Zim was on his knees before him, helpless and afraid. Dib felt the thrill of self-gratification. It was so sweet.

"Computer! Move him to the table," Dib ordered. "And pin him down." Zim flailed his little legs in protest as the strong cables dragged him to the hard metal surface, binding his hands and feet still. Whining, Zim arched and wriggled, trying to slip away, but the bonds were too tight. He was completely trapped.

Dib strolled over, reaching in his coat pocket for surgical gloves.

Snap!Snap! Both hands were now clad in white rubber. Humming to himself, Dib slowly slid off his trenchcoat and rolled up his sleeves. Zim felt his stomach clenching with fear. He could no longer watch the human; each of his movements oozed smug contentment. Zim was completely at Dib's mercy. It was revolting. It was terrifying. It was...
It was strangely thrilling, wasn't it?

The thought sprung into Zim's mind out of nowhere, sending him into a fit again.
"Disgusting meat-creature! Release me immediately or face horrible consequences! Nhh!"

Dib rolled his eyes, taking out a metal case full of sharp, unfriendly looking instruments.
"Enough already, Zi-"

"No!" Zim interrupted, catching a glimpse of the box. "This isn't fair! Using my own base to...don't...you can't do this!"

Dib turned to look at him, no longer smiling. "It's over, Zim. I was patient enough to fight with you all these years, but now I'm tired of it. You lost today."

Those words were too blunt. All the color seemed to drain out of Zim's face as he stared at his captor.

It seemed like Dib had been a little boy just months ago, glaring at Zim from across the classroom, full of energy and determination. Zim was only a target back then, an outlet for Dib's frustration. But now Dib was a man of 16. He had grown taller and stronger. He had learned from his mistakes. Compared to Irkens, humans matured in a flash. Zim just couldn't keep up. Through Dib's transformation, Zim remained static. Today he looked the same as he had at the beginning of it all.

"What are Irken soldiers supposed to do when they've been captured?" Dib's voice broke through Zim's reverie. "Struggle until the end, or quietly accept their fate?"

Zim was silent.

"The latter, then," laughed Dib.

Zim fixed him with a smoldering glare. "Never."

"Fine," said Dib, sounding pleased with Zim's defiance, "let's get started."

He reached into the case and pulled out a pair of extremely sharp looking scissors. Zim's eyes became impossibly large.

"Don't worry," Dib chuckled, beginning to cut a trail up Zim's invader uniform, "I'm not gonna use these to hurt you...yet."

"What do you think you're doing, earth stink?!" yelped Zim, continuing to struggle. "How dare you!"

"How d'you think I'm gonna examine you if your clothes are on?" Dib replied, voice tinged with annoyance, "Stop wriggling or you'll get cut sooner then I intend."

Gritting his teeth, Zim quieted, allowing Dib to peel off his tunic. It would be so convenient if Zim could shoot lasers from his eyes, since he was spending so much time glaring at the human.


Dib slashed careful paths down Zim's long sleeved shirt, frowning when he finally got that off too. Zim was wearing yet another shirt.

"Jesus, why do you wear so many clothes? It's summer, don't you get hot?" grumbled Dib, slicing away the final layer. At last, Zim's chest was now completely bare. Dib's breath caught in his throat, his eyes hungrily taking in the smooth, hairless skin. He'd always been itching to see what Zim looked like under that uniform. For the hell of it, Dib tugged Zim's black gloves off as well. The aliens two-fingered hands looked even stranger now. No nails, no knuckles, no fingerprints. Zim's body carried none of humanity's ugly wrinkles, pores, hair, or visible web of veins underneath. Models would die for it. No airbrushing required.

With a frustrated grunt, Dib peeled off one of his own gloves and succumbed to his urge to touch the alien. Slowly, he reached out and brushed his fingers against Zim's chest. Oh. It was so soft.

Dib hadn't noticed the alien was trembling until he touched him. Finally, he glanced up at Zim's face and felt an unexpected pang of guilt. He shouldn't have been feeling bad already; he had hardly done anything yet. But Dib had never before seen Zim look so utterly helpless. He'd never seen so much emotion welling in those big red eyes....they were so shiny, so mesmerizing. And Zim's antennae--had they ever flatted like that before? Zim looked like a kicked puppy, ears drooping in submission.

"D...don't look at me like that, Zim," Dib murmured, hand moving across Zim's chest and down to his waistband. The alien still had his pants on. More than anything, Dib was curious to see what Zim's most private area would look like. Zim was male, but did that mean the same thing that it meant for humans? Dib traced Zim's panty-line, teasing.
Enough. He needed to find out now. A scientific need, just a powerful scientific need. Dib inhaled. Why was he erect?

As soon as he hooked his thumbs under the band of Zim's pants he heard a sharp intake of breath. Zim had his eyes squeezed shut, head turned away from Dib.

"Honestly, Zim. If you're getting this upset now..."

"Shut up Dib-monkey!" Zim bit out. "It...it's embarrassing, that's all!"

Zim was embarrassed? He must be....there was a dark bluish purple flush across his face. Dib smirked again, holding back a laugh. Dib was going to redefine the meaning of 'embarrassing' for Zim tonight.

He suddenly yanked Zim's pants down, underwear and all.
The alien gasped and instinctively pulled his legs together as much as he could. The cool air of the base made him shiver, the strong light blinding him senseless. He'd never felt so exposed in his life.

Suddenly Dib stopped. As he looked at the little alien, recoiling in fear, he felt like a pervert. Was Zim always this thin and fragile looking? Dib knew Zim was a strong little guy, but now...Dib was much bigger than him. It was like he was molesting a child.

Dib frowned, eyes narrowing. No. Zim wasn't anything like a child. He was ruthless and evil, and tonight he was going to pay for it. Dib trailed one finger up Zim's leg. Zim froze, anticipating--then Dib grabbed both of Zim's thighs and forced them open.

There was no penis there, after all. Just a fleshy slit where it should have been, the skin around it swollen and purple, as if it had been bruised. And underneath...Dib lifted Zim's hips, finding another hole.

"Is this an...is this the same as a human's?" Dib prodded it with his gloved hand's forefinger. Zim yelped.

"Stop that! Of course its not the same as you humans' revolting filth-holes, you horrible meat-brained-"

"Then how do you excrete?" interrupted Dib, trying to remain in a scientific state of mind. It wasn't really working.

"My pak takes care of excess nutrients," Zim said shortly.

"Then what's this for?" Dib poked the hole again, earning a gasp from Zim that went straight to his groin. If the alien kept making sounds like that...

"N-nothing." Zim looked nervous, eyes darting about. "I don't use it."

Dib thought for a moment. "Interesting," he muttered, before fishing around in his metal case of horrors for something else.

"What are you gonna do now?" Zim demanded, ignoring the feeling of dread growing in the pit of his stomach.

"I don't think you're in any position to be asking questions here, Zim." Dib turned around, holding a long instrument with a small screen on the thicker end.

"What is that?"

Dib didn't answer. It looked like he was having a hard time concentrating as he removed the cap from one end of the device. His palms were sweaty.

"No..." Zim's voice sounded shaky, but this time it just encouraged Dib. He roughly pushed the thing in the alien's hole. Zim cried out, back arching at the intrusion.

"Stop it! Take it out! Take it-" his voice broke when Dib slid the thing out, then plunged it back inside again. Zim sucked in a shuddering breath, fists clenching. Dib watched him intently, then stopped, noticing that Zim's higher slit had begun to change. It looked like something wet was poking its head out from inside. Feeling Dib's eyes on him, Zim couldn't restrain it any longer. His length unsheathed itself.

Huh. So the alien had equipment after all.
"Oh? What's this?" Dib teased, grasping the organ between his thumb and forefinger. It was a little small compared to a human's, but it had the same shape.

"Don't t-touch, earth-stink, st..ah!" Dib began to rub it. Well, that's one way to shut him up. Grinning, Dib used his other hand to start pumping the device in Zim's backside again. Curiously, it was sliding in and out more smoothly than before. It appeared that Zim's second hole was wet now, as was the sex in Dib's other hand.

"I think you do use this other hole, Zim. It's working fine."

"No...that's the female part, I don't use it!"

Dib paused, intrigued. "Irkens have both?"

"Obviously, stupid human! What else would you be looking at?" Figuring this was a good way to stall Dib, he continued, "Irkens choose their preferred gender, and I decided I'm male. That means I don't use the female part, and you can't touch it, either! Now get your filthy hands off me!"

"Oh, well excuse me," said Dib in a mockingly apologetic tone, stabbing the device back inside, "I didn't mean to break the rules!"

Zim gasped, body jerking with each thrust. For a brief moment, Dib adjusted Zim's bonds so that the alien's legs were drawn up, then continued at a better angle. To make things more excruciating, the human was no longer touching Zim's male organ. Now, all Zim could feel was cold metal pounding deep inside of him. He stared at the ceiling, trying to will his mind away from the situation, but he couldn't. This felt good, no matter how much he hated to admit it. Dib's hot breath on his knees, his calloused fingers sliding up and down his sweat-slicked thighs--it felt good, it felt good, it felt good...

Zim's vision blurred. It was surprising that his tears didn't evaporate- his cheeks were so hot from blushing. A sob welling in his thought finally fought its way out, causing Dib's head to snap up.

"Zim?!"

Oh, he was really crying now. And Zim never cried.

"What's wrong? Did I-" Dib stopped mid-sentence, knowing how stupid his questions sounded. Of course something was wrong. He was raping Zim with a scientific probe-- he had him tied down in his own fucking base. It was natural for Zim to cry, but Dib never expected he'd do it. He didn't know he could.

"Shut up, don't look at me!" Zim struggled to keep his voice even. "Just get it over with already!"

Dib's shoulders drooped. After seeing Zim like this, there was so way he could continue things in the same sadistic way. Quickly Dib pulled off his other glove and reached out to brush his fingers against Zim's face. The alien flinched, stiffened, but was powerless to prevent Dib from touching him. The hands gently caressed their way up to Zim's antennae, which twitched in response. Dib stroked them, then pet Zim's wet cheeks and head. The decrease in tension was palpable and soon the alien had stopped crying. Zim finally looked up and the two of them locked eyes, holding their breaths.

"Okay," Dib said after what felt like an eternity, "I think you've had enough punishment for now." Of course, he wouldn't admit that he had actually lost his will to hurt Zim. The alien just continued to stare at Dib curiously, not trusting himself to speak.

Dib moved around to pull the device out, causing Zim to whimper. Even now, Dib still felt undeniably aroused. It was too late to pretend he was being scientific anymore, so he decided to do as he liked.

"You have pretty legs," Dib murmured, touching them. Zim's antennae perked forward, the flush returning to his face in a hurry. Tentatively, Dib leaned forward to plant a kiss Zim's thigh. When he heard no response from the alien, he continued to kiss the soft skin, making a trail downwards.

Now he could hear Zim's heavy breathing. When Dib paused in front of the space between Zim's legs, he noticed a heady scent coming from the other's body. It was so sweet, beckoning for him to come closer.

"Are....are you emitting pheromones at me or something?" Dib's mouth was almost too dry to speak.

"N-no!" said Zim quickly, "I'm not doing anything, I...I..."

Dib saw that fear in Zim's eyes again.
"You've never done this before, have you?"

"Never been tied down and molested by a human? No, can't say I have," Zim snapped, finding his wits.

Frowning, Dib pushed up on Zim's legs to allow better access. "Don't be so bitchy. I'm going to make you feel good now." Before Zim could protest, Dib bent down to lick the alien's still-erect sex. Zim cried out in alarm.

"Don't do that!"

"Does my saliva hurt you?" The taste in Dib's mouth wasn't unpleasant at all.

"N-no, but-"

Not caring what else Zim had to say, Dib descended upon him again. He sucked the swollen skin around Zim's sex, finally taking it between his lips and teasing it with his tongue. Zim couldn't find his voice to scream anymore. The warmth and wetness of Dib's mouth was too intense. Then he was jolted by the cold air when Dib let him go.

"Dib-worm!"

Dib blew on the alien's sex teasingly, then kissed the spot all over.
"Dib..."

The human's hands were roaming around Zim's body, pressing down on his belly, tickling his sides, stroking his neck...
Zim started to moan.

"Feels good?" Dib paused to lick his lips.
"No," Zim bit out stubbornly.

"Aw, embarrassed?"

"I hate you!" Zim blurted.

"No, then?" Unnerved, Dib kissed Zim's stomach, sucking on the soft skin, then laving it over with his tongue. "Maybe you'd have some more shame if I called your leaders and let them see you now?" The human looked up, raising his eyebrows.

Zim feigned disbelief. "Stupid human, you couldn't possibly-"
"Believe me, I know how."

Zim blanched, trembling with anger and humiliation. "Horrible meat creature, you're not fit for a junkyard-"

With that, Dib got up and started for the monitor.
"If you promise to be good, I might change my mind," he said airily, finger inching towards a certain button.

Zim's imagination couldn't fathom the ignominy of letting his Tallests see him in this condition. No matter what, he couldn't..

"Dib-human, wait!"

"Yes?"

"...don't," Zim said in a small voice.

"Then promise."
Dib sauntered back over, that smirk back on his face.

"I.." Zim averted his eyes, almost unable to bear this. "I'll...I'll be good."

"Good," Dib practically purred, resuming his position between Zim's legs. This time he turned his attention to Zim's other hole, which was still slick from the probe. Dib flicked his tongue at it, covering it in his hot breath. Zim began to wriggle in protest, but his legs were soon immobile in Dib's vice-like grip. He had no choice but to lie there and endure it.

Dib's own member was painfully hard now as he breathed in Zim's intoxicating scent, licking with increased fervor. Both were suprised when Zim let out a long moan, since he had only allowed himself small whimpers and groans up until now. The sound would put a AV actress to shame.

"Fuck, Zim," Dib growled, attacking the hole with his tongue again and again. Strong hands grabbed Zim's ass and pulled him closer.

"No more...Dib human....horrible...hate....no..." Zim tried to protest between gasps.

"You said you'd be good." Dib massaged Zim's backside and thighs, washing the little hole with deep, languid strokes. "Tell me how good it feels."

"No.."

Dib stuck his tongue in.

"Nghh! Nhh...ah...it feels good, it feels good!" Zim cried.

"That's it," came Dib's husky reply. He rubbed Zim's thighs, dipping his tongue in and out.
"Don't...no...ah...."
"Say my name," Dib growled, inserting a wet finger into the hole.

"Dib!" Zim arched off the table, body tense as a bow. "Dib....Dib..."

"Good boy..." Dib felt around in there experimentally, then poked another finger inside. "Tell me what you want."

"No," said Zim with gritted teeth, feeling tears well up again.

"Fine." Zim couldn't see, but he heard the sound of a zipper and the rustle of clothing. "Zim, I can't wait for you. You're driving me crazy..."

Dib positioned himself before the Zim, who almost jumped out of his skin when he felt something hot against his hole.

"D-Dib-worm?" Zim could see the pained look on the human's face now, he could feel hands running over the curve of his waist, his chest, almost reverently.

"You're so fucking sexy." Dib drank in the sight; Zim's legs spread open invitingly, his skin flushed and sweaty, his lips parted, his jewel-like eyes shinier than he'd ever seen them before, pleading him to, begging him to...

"Tell me to do it," Dib croaked, self-control running thin.

Zim stared miserably. The heat of Dib's organ was maddening. He could feel his hole twitching against it, betraying how badly it needed Dib inside him. And he couldn't tear his eyes away from Dib's body; his well-formed chest, his abs clenching with desire, the beads of sweat trailing down his muscles, his brow knitted with frustration, his golden eyes burning...

"Oh," Zim chocked.

Unable to control himself any longer, Dib slammed into Zim with a strangled moan. Zim's head snapped back with the force. He screamed.

"Fuck," Dib hissed. Zim was incredibly tight, unbearably hot. Amazing.
Whimpers interrupted Dib's dazed state. The alien was writhing in discomfort, head jerking from side to side.

"Shh," he tried to soothe Zim, "it'll feel good soon, don't wo-"
"Horrible stink beast! It hurts!" Zim whined, "Why on Irk are you so hu..hu..." Zim lost his voice again when Dib shifted. "H-huge..."
"I think you'll get used to it," Dib said, struggling to restrain himself. The sight of his cock buried in that tight little ass made him want to fuck the alien senseless...On impulse, Dib grabbed Zim's slim waist and pulled him forward so he was completely impaled.

"Yess..."Dib hissed, leaning down to kiss the arch of Zim's stomach. "So good..."

"D..nh...Dib...Dib," Zim moaned, chest heaving, body clenching and twitching around Dib's cock.

Dib began to move, holding Zim in place by his hips and pounding into his hole.
"Yeah, that's it," Dib babbled senselessly, "fuck, you're so good, so pretty..."

Zim couldn't mistake the affection in Dib's voice. It was so desperate and intense, like he needed him, and Zim had never truly felt needed before. He looked up into the human's eyes, misty with passion, and began to drown.

"Dib," he whispered again, unable to say anything else.

"Zim. Zim. Oh god, I...shit," Dib mumbled horsely, increasing the pace. Then he hit something that made Zim keen.

"Dib!" His hips began bucking wildly. "Dib, that, don't stop, good, yes..."

"You like that?" Dib panted and kept thrusting. "Right there?"

Zim screamed as Dib struck that sensitive bundle of nerves again. Wincing, Dib struggled to maintain the same angle, but his knees were slipping on the metal table, and Zim's back was already bent to what looked like a painful degree...

"Oh," Zim gasped, "no, let me go, let me...l-let me touch..." The alien began to strain at his bonds once more.

Dib stopped, eyes raking over Zim's face suspiciously.

Zim stared back, mustering up his courage. "Please," he whispered.

In this situation, Dib would have to take his chances.

"Computer, release him."

The cables slid off Zim's wrists and ankles like harmless vines, revealing angry marks. Still inside, Dib watched Zim apprehensively, wondering if the alien would make a run for it.
Slowly, Zim reached out. Dib willed himself not to move, even if Zim was about to strike him. Instead, the alien pushed down on his shoulders, forcing him into a sitting position. They gasped as their bare chests rubbed together. Then Zim pulled back, his stare somehow penetrating and pleading at once. The two of them stayed like that for a few long moments, Zim kneeling in Dib's lap, Dib's member still inside of him, neither moving an inch.

Suddenly, Zim kissed him. It was the last thing Dib had expected him to do. He couldn't believe he wasn't dreaming as Zim's soft lips moved against his own in a kiss so sweet, it made his chest ache.

"Zim," Dib murmured when they parted for breath. Zim's hands were trembling on Dib's shoulders, his expression unreadable.

Then Dib dove in to capture the alien's lower lip in a dominating, passionate kiss. He moved one hand over the smooth expanse of Zim's back and the curve of his ass. Zim began to buck against him again, muscles tightening around Dib's cock. Dib groaned.

"Is this okay?" he rasped, eager to continue. Zim didn't respond, but tentatively reached out to touch Dib's hair instead. Dib waited. Then the alien closed his eyes and lifted his hips, only to forcefully impale himself on Dib's hard member again.

Dib let out an animalistic noise that was half growl, half gasp. Holding onto the human as if his life depended on it, Zim continued to bounce up and down. He knew just how to come down on Dib's cock so it hit that spot deep inside him.

"Oh yeah," Dib mumbled, entranced by Zim's expression--he looked so ashamed, so wanton, so rapturous, so reluctantly submissive, all at once. "Ride that cock, baby, you like that? You like to be fucked don't you, you little slut.."

Zim couldn't stop to ask what a slut was- he was increasing his pace, slamming down with a wet squelch over and over. He gazed at Dib deliriously from under heavy lids, eyes shining like rubies.
Dib kissed him again, cradling his head tenderly, caressing his frantically twitching antennae. He licked at the other's lips, trailing kisses carefully over Zim's cheeks and eyelids.

"Dib," Zim moaned. It felt so good to call his name.

Dib reached down to brush Zim's male sex with his fingers, causing Zim to tense up. Bringing himself down upon Dib's cock one last time, Zim finally came, spurting all over his belly. The sound the alien made then sent Dib over the edge too. Zim gasped and whimpered, shivering as his orgasm washed over him, along with the warmth of Dib's seed.

The two of them collapsed onto the table, wrapped tightly around each other. Zim pushed himself as close as he could to Dib's strong chest and they kissed lazily for a while.
Zim murmured in confusion when Dib slid off.

"You're all sticky..."

Before Zim could inform Dib of whose fault that was, he was cut off when Dib began to lap at his entrance. Zim mewled and sighed contentedly as Dib soothed the pain there, cleaning up the sticky cum.

"Ooh, Dib..."

After a moment, Zim's fingers wound themselves in Dib's hair, urging him to come up. Dib grinned sheepishly and lowered himself into Zim's arms.

They lay like that for a few minutes. Zim's brain began to awake from its sex-induced daze, and he finally spoke up; "I thought you said you were going to kill me."

Dib frowned and kissed Zim on the cheek. "I couldn't do that."

"Oh," muttered Zim, feeling his face grow hot for some reason, "Good."

Pause.

"And Dib-human?"

"Just Dib," said Dib in warning tones.

"Dib?"

"Yes?"

"What did you do with GIR?"

"Just gave him some videos."

"Oh."
