With a mellow sigh that would've embarrassed him, had Dib even noticed he'd done it, he leaned forward a bit to put more pressure into the embrace. His hands curled into the sides of the pilot's chair, nails scratching against the fabric.

Zim was a bit surprised at the sudden enthusiasm within the kiss, but relaxed after a bit and welcomed it. He couldn't help but smile a bit into the kiss as he draped his arms over Dib's shoulders. The alien pressed himself against the human, longing to be close and to feel his warmth. His bare hands running through Dib's unruly hair softly, caressing and petting involuntarily.

Each breath the human let out against Zim's skin sent his 'spooch fluttering against his chest; he was much more aware of the human than the previous times they had been together like this. He had to pull back a bit and take a deep breath.

"It feels like my squeedily-spooch is going to burst out of my chest…" Zim whispered nervously, putting a hand to his chest, as if to hold it in. This was such a strange new feeling to Zim, he didn't know if he should be worried or not—though was feeling a little worried anyway. He felt that he could handle it better if he just knew why he was feeling this way.

'I'm shaking.' Dib thought distantly, licking his lips to taste more of Zim. More vanilla crème. More danger and stubborn alien on his tounge. Running on instinct, he trailed his hands up Zim's arms, grabbing his wrists and pulling them away from his chest. A few seconds of debate before Dib ran his lips along the irken's forearm, tugging the sleeve up with his teeth till he reached the crook of a jade elbow, placing a small kiss there.

The alien's pulse thumped erratically against his mouth. "I—" Golden eyes seemed foggy and distant as if there was too much going on inside. "Me too."

It was true. He could hear the erythematic thud of it in his ears. It beat against his chest, too fast, pumping too much blood that it made Dib flushed and overheated. This was…ridiculous. Or would've been. Should've been. If only it was…

If only it was so simple as to be a mistake, to be a collapse of judgment due to alcohol or a moment of temporary insanity. But, Dib knew exactly what he was doing and the more that he stared at all that jade skin, into those giant crimson eyes…the more he was sure of what he wanted.

The feel of those soft lips trailing up his arm sent shivers through the alien, turning his violet face away in slight embarrassment. What was happening to him? Why was he feeling this way? He didn't understand it, but as Dib murmured into Zim's elbow, he gave up hope in fighting it.

Dib was feeling this way too, and even though it was surprising to hear, Zim felt like he always knew this. And maybe it was ok to not understand. He knew that Dib was with him and that they were sharing this moment, and that's all he needed.

Pulling away for a moment, Zim turned his body to fully embrace the human, setting his legs on either side of Dib—straddling him. He cupped Dib's face in his clawed fingers and gave him a soft, affectionate kiss before trailing down to his neck, planting small kisses against the warm, exposed skin.

Hissing in shock, Dib blinked too much, his head falling backwards to let the irken have easier access to more skin. Unclenching them from the seat, his hands flew up to Zim's waist, gripping it tightly. Half out of out of frantic desire, the urge to have something to ground himself and half out of fear of what was happening between them.

"Z-Zim…" The irken's name finally worked itself past the teen's tight throat. The tiny kisses against his sensitive skin sent shivers all the way down to his toes and with each new one, his breath hitched up in his throat.

Dib bit down on his bottom lip, feeling nervous energy working its wicked way up his spine and he began to massage his companion's hips, slowly working the long dress-like uniform up Zim's lithe form.

Hearing his name come from the human under him made new desires to rise within him. He wanted desperately to make the boy say his name again, in that desperate, pleading tone—to make him beg and whine for more, which Zim was all too glad to give.

Zim gently nibbled the sensitive skin, licking between each teasing bite to soothe the spot before nipping again. The human's flavor lingered long after he pulled away to help Dib pull off his uniform. For the third time, Zim was half naked in front of Dib, hickies still fresh and vibrant against his jade skin.

Swallowing back a moan at the sight, Dib reached out and ran a hand down the irken's body, fingers tracing each hickey and bruise. Mentally remembering each little scar that marred emerald skin. It was hard to breathe, but he panted and leaned forward, placing a wet kiss against the alien's collar bone where a hickey stood out sharply, a sapphire amongst the emerald.

"You're…" The dim, hardly there glow of the distant stars, the sun and the tiny shimmers of Earth's billions of lights all left the alien bathed in a smoldering kaleidoscope of colors. "horrible…" You're beautiful. Exotic and unlike anyone on Earth. Unlike anyone in the entire universe.

Zim inhaled sharply as Dib planted the kiss against his collar bone, running a hand through his hair roughly as he did so. Dib was so close now…closer now than he had ever been, it felt like. And yet it seemed that there was still some distance that could be closed between them, and Zim couldn't stand it.

Dib's breath was hot against his neck as he spoke, and he could only chuckle dryly, not sure if he could remember how to speak.

"You don't seem to mind." Zim whispered as he snaked a hand underneath the human's shirt, running the palm of his bare hand against his skin.

"Maybe…" Dib cleared his throat because it sounded like he was being choked only to nearly actually choke on his tounge when Zim's slightly chilly fingers brushed so teasingly against his stomach. "it's because I'm used to it." Or because you're addictive…you stupid, stupid creature.

Dib's hands connected behind the irken's back and pulled Zim closer, feeling the need to bring Zim as close as physically possible. To eat him up and keep him locked away, to never let go and be kept. Ridiculous thoughts just seemed to keep pouring into his slowing thought process, as the human leaned his head against his friend's chest to listen for the squeedely spooch he'd imagined a million times.

It beat frantically against his cheek, echoing in his ears and connecting to him in a way that seeped through all the holes and cracks that weren't tainted by Zim, ruining and fixing them. He was suddenly desperate to claim…to be claimed…to have that steady rhythm under him and over him. All around him.

He bit down on the bruise already forming just slightly above the irken's collarbone, not hard enough to draw blood but, definitely enough to make a mark. Then Dib soothed the hurt with his tounge, eyebrows drawn in concentration.

Zim didn't need to press any farther, as he knew that what Dib claimed wasn't exactly true. He knew Dib was feeling what he was; the need to be close, the need to belong to the other, and the need to know each other. To know what was behind those burning eyes, and to claim it—to hold it close and protect it from the crushing world that sought to extinguish it.

And even if Zim had wanted to press farther, he found that he wasn't able to. It was all he could do to keep breathing as the human nipped at his already bruised skin, eliciting a small moan from the alien.

He brought his legs up and hitched them around the human, bringing their lower halves closer, and successfully imprisoning the human against him. His hand ran upwards against Dib's chest, taking in the texture of the impossibly warm skin and bringing up his shirt as he did so. His claws lingered over each scar that stood out, running the pads of his fingers over them softly. He hissed softly against Dib's ear before whispering his name longingly.

The human was hanging on the edge of control when Zim wrapped his short but skinny legs around his waist, clinging to the last of his sanity, holding himself together by a string.

"Dib…"His name, without a horrid suffix. His name wrung from the lips of the usually hot headed and stubborn alien all but shattered him. It was violent, this snapping of control and Dib let out a groan, hands slipping back over the irken's chest and down to his hips, digging blunt fingertips into the jade flesh before he thrust upward, forcing friction between their clothed lower bodies.

Sparks. Pure electricity and it should've felt so wrong but, it felt so right with Zim above him. The teenager's mind was racing with too many thoughts, all of them revolving around the alien he rutted against mindlessly.

Zim's back arched as a moan ripped itself from his throat; the human's desire erupted from underneath him and sent Zim over the edge. Those ravenous hands that gripped his hips as Dib thrust against him was the only thing that seemed to keep him grounded.

Zim's hands fumbled with Dib's shirt until he finally managed to tear it off the human's frame, tossing it aside. He leaned forward and licked hungrily at the newly exposed skin, his hands roaming anxiously as he did so. His tongue trailed against Dib's chest wetly, lingering slightly over his nipples until his hands reached Dib's hips, claws digging themselves under the band of his pants, sat up a bit and looked down at Dib's pants, both eager and nervous.

Gasping for air, Dib wrapped a hand around the back of Zim's neck and brought him down for a hungry kiss, flicking his own tounge across the irken's sweet lips, teasing his mouth open and twining their tongues in a heated dance before pulling away and nodding faintly. With grunts of frustration, the human undid the seemingly infinite amount of buttons and buckles and zippers until they were down around his ankles.

Left only in his boots, socks and nerdy UFO boxers, Dib shivered. They were in space after all. Impatient, he hooked his thumbs into the waistband of Zim's leggings, raising an eyebrow, silently asking for mercy and permission. But, mostly mercy.

Zim watched eagerly as the human undressed in front of him. Only to realize that he had even more clothes underneath. Zim gave a small huff of frustration, but sat up as the human tugged suggestively at his own clothes.

Zim bit his lip, but nodded in return. He helped Dib pull down his leggings, which slid off effortlessly, taking the boots with them as they went. Unlike the human, Zim was not equipped with underwear, and he sat exposed on his lap.

Zim had experienced erections before in the past, but they were always fleeting and went away on their own. Now as he sat, naked on his friend's lap, he felt a tad embarrassed at how his body was reacting. The magenta skin of his member was moist, and glistened readily as Zim panted heavily, not sure what was going to happen next.

Swallowing back the huge lump of nervousness that had suddenly lodged itself in his throat, Dib's eyes flickered from Zim's member to the large ruby eyes that seemed to beg for something. For release, for guidance. Well, Dib wasn't exactly an expert. This was his first time doing anything like this with anyone…let alone a guy or an alien.

Biting down on his bottom lip, the human mustered up all that bravery he kept stored up, kissing Zim lightly on his chin before tentatively reaching out and running the very tips of his finger tips along the sides. The sensation was beyond anything he'd expected.

Not that he'd known what to expect. It was ridged kind of like Zim's tounge, soft but…also hard. Dib nearly choked on his tounge again, wanting to pull away because THIS WAS HAPPENING but, wanting to throw himself into everything because he wanted THIS more than anything he could remember.

Zim's body quivered at the feel of those warm fingers against him. He felt everything melt under Dib's touch, and everything seemed so impossibly strange, but felt so right to the alien. He didn't want to think about it; he didn't want to think about how he still was quite uncertain of what was happening, or that his instincts were telling him that because Dib was a male he wasn't quite sure how this was going to happen, whatever THIS was.

All he wanted to think about was the human in front of him. He wanted Dib to consume him and leave little else in this world for him. And the more Zim thought about it, the more it drove him crazy. He panted softly and let out Dib's name in a soft pleading tone.

That tone encouraged Dib to take the leap and wrap his entire hand around the irken, stroking up and down in a steady rhythm, eyes glued to Zim's expressions. He hungrily ate up any small noise, any differentiation in the alien's expressive face.

Bringing Zim pleasure brought him pleasure, every hitch in breath, every soft sigh. And Zim was squirming everywhere, which was dangerous considering they were in a space ship. But, that thought was fleeting, as he was distracted by his name rolling off an long, prehensile tounge. 'More', was his instant instinct.

Zim squirmed on Dib's lap, his legs moving with him as he thrust instinctively against the palm of the human's hand. Nothing seemed to make sense anymore; his body screamed for more while also begging for a release. His breath came out in moans and whimpers as Dib worked him, occasionally breathing a word of approval. He clutched onto the human for support, as he could no longer sense the Voot around them, and felt as though they were suspended in space and would drift apart if he let go.

"Perfect…beautiful…" Dib whispered unable to help himself, his unoccupied hand pressing down on Zim chest to shove him backwards, leaning against the control panel. The entire universe seemed to be spinning, revolving around them. This moment that he never would've thought in a billion years would happen a few months ago.

Removing his hand, Dib kissed his way up the inside of the irken's thigh, eyes alert for any sign of surrender. Zim was always so dominant. So commanding and high strung…this was like a drug to have control. To wring helpless sighs and whimpers, to hear his name as it hissed from in between clenched teeth.

Zim couldn't help but utter a small purr as he felt those lips move up against the sensitive skin, closer and closer…He looked down at Dib, a puzzled expression on his face. He didn't want Dib to stop, and his member throbbed at the sudden abandonment.

"Don't stop, Dib…" He commanded softly. He had to gain back control, somehow, and he knew it. He felt so lost, and Dib seemed to know the motions to go through, but Zim couldn't help but feel a bit reluctant to let the human dominate him so easily.

" 'M not. Be patient." Smirking nervously, Dib tilted his head to the side, biting down on his bottom lip and staring at the daunting task before him. This was obviously not something he'd ever practiced before..or spent much time researching. But, the whole idea seemed easy enough, even though there might be some sort of different species thing to factor in.

Shaking his head, Dib licked his lips threw all contemplation out the window. He started slowly at first. AS he had with his hand. Except instead of finger tips it was the tip of his tounge, testing, tasting. Of course he was sweet there too. He was sweet everywhere…

Zim's brow furrowed and he gasped; the feel of Dib's tongue on his member sending waves of white hot pleasure to ripple through him. His toes curled as he brought a hand to Dib's head, encouraging him to continue. He spread his legs to allow his friend more access to as much of the sensitive area as possible, his breath leaving him in heavy, loud moans.

It was encouraging to have Zim practically melting beneath him. Sharp claws curled into his hair, scraping his scalp and Dib didn't mind, taking a deep breath before setting more of his mouth over the irken's member. He ran his tounge up and down the soft ridges.

Experimenting with different kinds of suction and head movements, enjoying taking apart the irken's hard control as much as Zim was obviously enjoying it if the ankles digging into his back were any confirmation.

Zim clutched onto a patch of Dib's hair as his head bobbed between his legs, the Irken squirming and thrusting before below him. His whole body flushed as his 'spooch pumped harder with each second, moaning and whimpering for the human.

He could feel it start to build up, and it was beginning to become too much for him. He almost asked Dib to stop, but he couldn't bear the idea at the same time. He was going mad until finally the alien released himself.

The pleasure gripped him, his whole body tense and quaking as he climaxed.
Zim let out a few more fading whimpers, then went limp across the control panel, panting heavily, his chest rising and falling dramatically.

Despite the fact that Dib expected it to happen, he still nearly reeled backwards when the sweet fluid flooded his mouth. Still he managed to get most of it, swallowing it wondering if that had been a smart idea and deciding that he would find out later if his body agreed with it or not. Wiping a drop from his chin, the human sat back in the chair, feeling as if he'd done something monumental.

Zim looked burnt out, eyes wide and his chest finally starting to slow to a even breathing pace. Dib shifted in the chair, uncomfortable in his stupid boxers. Stupid hormones. Stupid Zim…being all obnoxious and fucking edible.

Zim propped himself up on his elbows to look at Dib, still reeling from what had just happened. What HAD just happened? He wasn't quite sure, to be honest. None of his training had prepared him for something like that. Hormones buzzed around in the air, making it hard for the Irken to focus. He watched Dib for a moment before crawling back over to him and setting himself back down on his lap.

He cleared his throat nervously. His skin was still flushed and warm, and he seemed a bit uncomfortable as a bead of sweat that had form rolled down the side of his head.
"So…" He began tentatively. "Did…did we…?" He could hardly even bring himself to say the word. How did he ask his friend if they had just mated? He knew what mating entailed, but what went into it exactly was sort of a grey area of the alien.

Grunting, Dib worked to shift Zim on his lap so that it wasn't painful. But the irken's question threw him off guard. He chuckled very softly before nipping his chin. "No. That was…what some people call foreplay. I think. Um, sex happens differently than that. Or at least that's not what the 'main event' is supposed to be. I-I don't know." At least the last time he checked in with his Health class it had.

Dib couldn't help but feel completely distracted. By everything at the current moment; Zim's slightly blue flushes face, the stars outside the steamed up ship but, mostly how uncomfortable his erection was. Dib was teenage boy. Of course he'd had one. Many of them on different horrible occasions all caused from stupid things. It was a natural if humiliating experience. But, this was different. This was expectant and caused by something that wasn't a dream or his pants.

Zim shifted on Dib's lap uncomfortably, having a hard time finding a comfortable position to sit in. "Sex?" He questioned. Was that what they called mating on Earth? He opened his mouth to say something, but only growled when he felt Dib's erection poking at him again. He leaned back to get a closer look at the culprit, examining the tightness of the human's boxers.

Hesitantly, he reached down and softly prodded the erection through Dib's underwear.
Dib opened his mouth to answer the irken's question. Or at least the silent obvious one. Only to nearly shriek, lifting his knee up a bit to create a tiny barrier. "Um. Yes. Sex and that is kind of like what you have." The human gestured to Zim still protruding member.

"Only it doesn't conveniently fold up like yours seems to be able to do…but then again I am just a pathetic human…" He was babbling. He did that when he felt awkward.
Zim jumped back at the sudden, unexpected yelp that Dib let out.

'Like what I have?' Zim thought, curious. He leaned forward again, pushing away Dib's knee despite the obvious reason that he had put it up in the first place. He had now forgotten his previous question about sex, as he had found something a bit more interesting. He had to admit that he had always been a bit curious about human anatomy. Not to mention that Zim was stark naked while Dib hid behind his garments, and that just wasn't fair at all.

"Yes, you are…" Zim agreed absentmindedly as he crawled over Dib, slowly, and reaching out to pull back the band on his boxers.

"I'm what?" Having totally forgotten what he had said in the sudden wake of Irken curiosity, Dib let it happen, but bit down on his lip. It was one thing to expose Zim and explore him. Quite another to allow another to do it to him. Showing himself off…Dib covered up as much of his body as often as possible…this was weird.

Once Zim had the boxers off, Dib shivered and his blush increased nearly tenfold, covering his neck and shoulders as he stared anywhere but directly at Zim. He was hard as a rock, and who could blame him?

Zim was a little surprised by how much it actually resembled his own, but was still taken aback by the sight of it. It was oddly…erotic. Zim felt his face flush as he examined it, but more so at the way Dib was acting so bashful by it.

There was a moment of hesitation as Zim tried to figure out the best way to approach the situation. Finally he slowly brought his hand down and gently caressed the skin with the pads of his fingers. The skin was dry, but oddly soft, while the member itself was firm. Zim couldn't help but flush even more as he touched it. He looked up at Dib, only to see that he had bitten through his huffed and flicked his tongue across the human's wounded lip, licking up most of the blood.

Shuddering in surrender at the gentle touches, Dib all but stopped himself from cumming right then and there, furrowing his brows and curling his hands into the arms of the pilot chair as he let Zim explore. There was a flick of an irken tounge against his lips, licking up the blood he'd unwittingly drawn and it in turn drew a approving groan.

"Z-Zim…" Breathlessly Dib squirmed, opening his eyes to watch, gulping back big lungfuls of recycled air and not caring. At first he's been apprehensive of Zim's reaction…but, the irken seemed to enjoy…looking at him and touching him. Which was currently his problem.

The human's toes curled helplessly against the cool metal floor.

Zim purred softly at the sound of Dib's approving moans, coaxing him to explore a bit farther. He wanted to make Dib feel what he felt earlier, to make him beg for mercy until he erupted.

The Irken wrapped his fingers around Dib's throbbing member, being careful not to get his claws involved, and gently stroked him in a slow rhythm. He watched Dib's face with half-lidded eyes, wanting to see the human's flush face as he uttered each moan. He wanted to see Dib's face as he called out to Zim.

Breathing got harder the longer the delicious torture continued, Dib was unable to do anything but give into the sensations and hope he didn't die. Against his will and better judgment, pitiful whimpers and moans that seemed to have come from the very pit of his being were torn from his throat.

Swallowing back a scream, instead he ground out the Invader's name, cursing it and praying to God. "Oh God, Zim!" The sensations kept bubbling up, never allowed a respite. His head thrashed from side to side, his body writhed and he wanted to pull away because it was all too much. But, it was never enough and he wanted more.

So much more. Of this. Of Zim. Of them…
