OH my goodness. I forgot to post this chapter. I am so sorry! But now the next one is ready so have two chapters at once!

Zim could understand the human's distress, so he explained to reassure the human he wasn't doing the same experiments he threatened when they were enemies. "Irkens and humans mate in similar ways, but Irken bonding is complex and permanent. If we are to properly bond I need to find a way to replicate the bonding effects in you. So I can get the proper readings we will mate using this," Zim said carrying Dib over to a special contraption he had the computer make along with the other mating tools.

"I was going to wait to use this, but since we don't need to do any of those other disgusting human mating rituals, we can start now," Zim said and laid the human out on the specially made surface.

It's design was deceptively simple and had probably escaped Dib's notice as it just resembled a decently sized mattress lying on the floor. However, instead of fabric it was made of a soft plastic similar to silicon. Malleable and squishy the mattress dipped slightly with Dib's added weight, however it was firm enough to not sag completely to give them both the ease of movement.

Inside the mattress was the real genius of technology. While Dib slept over the past two nights Zim had run several scans on the unaware human. He wanted to quickly find a way to bond with him. While he increased his biological knowledge of Dib's body, he was still missing some key data. He needed chemical, scent and brainwave data of Dib's body in a mating state. So Zim created this surface that would allow for mating, while also obtaining the necessary data.

While Dib was still immobile Zim attached a thin band to each of Dib's wrists, around his ankles and another band around his forehead. The bands formed to Dib's skin and would help gather the data Zim needed without getting in the way of their mating. As a bonus feature, the bands could adhere themselves to the mattress acting as very effective bindings.

However, for the machine to get completely accurate readings, Dib would first need to be in a relaxed state, but still exhibiting the mating signs which was why Zim dug out the handcuffs he made a long time ago but never had a chance to use. The human was way too squirmy to relax and lie still on his own.

After all the bands were in place, Zim stepped back and using a program in his PAK and began the syronizing scan. Dib was still making slightly upset noises which was causing the scan to not proper sync.

"Dib stop your noise tube," Zim demanded. "We will continue mating as soon as the calibration is complete. I am simply collecting data on your inferior Earth body so I can find a way to properly bond with you."

Dib noises died down and finally the machine properly synched to Dib's body readings. Checking the system once more and finding everything in order, Zim climbed onto the mattress and removed the cuffs. The drug should be wearing off soon and they were not necessary anymore.

A twitch of Dib's fingers was all the warning Zim had before Dib's fist swung and landed a solid blow to Zim's head. The punch had been completely unexpected and Zim fell over.

"Zim already won! You submitted," Zim said accusingly and confused at Dib's sudden attack.

"I didn't agree to being drugged against my will, Zim!" Dib shot back and then looked around him and at the bands Zim had placed on him. "What are these?"

"I told you," Zim said grumpily sitting up. "They are to get accurate readings. I need more data before we can bond properly."

Dib pushed down on the weird surface they were sitting on. "Why didn't you explain that first?" he asked. He supposed he couldn't be too mad since Zim had only done this because he wanted a way for them to bond like how his species did, though Dib still didn't understand what he meant when he said bonds were permanent and made them unable to bond with others. However, a sudden horrible idea came to him. "You're not going to try rewiring my brain or something are you?" he knew Zim wasn't above that considering that one time with with Keef when Zim replaced the poor boy's eyes.

"I am still researching methods," Zim said but then pinned him with a hard stare. "But if anyone is going to rewire your brain meats it will be me," he glared at Dib, still a little upset that his human would allow another to mess with his mind.

Dib sighed. "You know I already called my dad back and left him another message." He'd called back not too long after their first mating, at Zim's insistence. Of course, he was only able to connect with the voicemail, but Dib didn't expected anything less.

"Hmph," Zim said still not completely satisfied. The idea of another stinky human poking around in his human's brain was enough to set him on edge. Especially since he hadn't properly bonded with Dib yet. The human was his and he was the Dib's Hive, but the bond was different. It was permanent and personal, something that would belong solely to Zim. His PAK then reminded him of something very important, which brought him back to the necessity of this mating.

With a thought to his PAK, the bands on Dib's wrists activated and like a magnetic force latched themselves to the surface of the mattress. Dib let out a startled yelp as his arms were suddenly flung out and backwards causing him to flop back. Glaring at one wrist he tried to lift it off the surface of the mattress but found it was impossible, it was as sturdy as any metal restraint. The material bent and flexed with his wrists' movement, making it seem like some invisible force was holding him down instead.

Dib felt the mattress shift around him and snapped his attention upwards to glare at Zim as he loomed over him. However, any complaint he had fizzled out when he saw Zim's heated gaze. Zim's long pink tongue slipped out as his antennae fell forward. The black stalks twitched in the air and Zim's open-mouthed grin widened. Leaning forward, his antennae's light feathery tips brushed against Dib's forehead as the tip of Zim's tongue lightly dragged along Dib's lower lip.

Zim made an approving sound. "Yes, this is the scent," he said sitting back on Dib's thighs. He took off one glove then the other and flexed his naked claws in the air. Immensely pleased at Dib's scent and the submissive yet anticipatory look on his face, Zim gently placed his hands on the human's chest, lightly gripping his ribcage. If he wanted to, Zim could dig his claws into the human's ribs and tear the human open. His smaller self wouldn't have had the leverage or strength to do so, but now that he was taller such a feat would be easy for him.

To remind the human that Zim was superior and stronger and had won dominance due to this, he applied just the slightest of pressure to his claws, digging the points into the skin soft between his ribs. The human flinched at the pinpricks of pain as Zim broke the surface of the skin. However, the scent didn't diminish if anything if heightened.

Removing his claws, Zim watched as small droplets of blood pooled to the surface. For a moment it looked like small red gems adorned Dib's skin. One droplet broke and slid down Dib's side where it was absorbed into the surface of the mattress. A small ding went off inside his PAK, audible only to Zim, informing him that one item off his checklist of required samples had been collected. He had plenty of Dib's blood on file and only needed data from any chemical changes in his blood during the various mating stages.

A second alert went off indicating that the brainwaves of this stage had been logged away, this was shortly followed by a third as scent data was gathered as well. Good. That meant he could proceed onto the next stage.

"If you could remain still and Zim could trust that your curious tendencies would stay in check, these would be unnecessary," Zim said tapping the bonds on Dib's wrists. "But last time your wiggly fingers found their way to my antennae."

"So does that mean that if I was unrestrained you would be worried about me regaining the upper hand?" Dib asked with a sly yet heated smile of his own. While Zim was stronger and won their physical fight, he was weak to pleasure and his antennae were his weakest points.

Zim scowled down at Dib and flattened his antennae against his head even though he knew Dib could not reach them. He hadn't meant to remind the human of his advantage in mating, but now that Dib said it he couldn't deny it. Dib had won the last battle, while Dib was smaller he was also a Taller and his to-be-bonding partner thus Zim's equal as well.

"Yes," Zim hissed reluctantly. "Which is why in my superior genius I decided to pin down your hands to the side. I won dominance. You will be submissive," Zim paused as he thought. "However, for another mating session a continuous dominance battle does not sound bad." It would be thrilling in several ways.

"You don't want to try that now?" Dib said trying to persuade Zim into freeing him. Just remembering the sight and sounds of Zim as his body succumbed to pleasure was enough to arouse Dib.

"Nice try, Dib-thing," Zim grinned down at him and laid his hands on Dib's chest, spreading out his claws to cover as much of his chest as he could. Very purposely Zim moved one claw to circle around Dib's nipple without touching it. Dib sucked in air through his teeth and Zim felt his body tense in anticipation. Grinning, he did the same to the other side slowly circling without touching. His eyes intently watched Dib's face, as Dib watched Zim's hands.

Zim slipped his tongue out once more and slowly lowered to hover above Dib's chest. Dib watched with anticipation, but feeling Zim's gaze he shifted to watch Zim's eyes. They were so alien with deep pools of a dark pink, almost red. Even if there was no pupil Dib could tell that Zim was looking at him. God, Zim was beautiful. Dark, exotic and terrifyingly beautiful.

Zim flicked his tongue, drawing the human's attention back to the long appendage that wiggled just above his nipple. Zim was teasing him. Taunting him. Zim knew that those were sensitive areas he was torturing Dib with the sensations. Touching him enough to want more, and close enough that Dib could almost feel the sensation, yet delaying it.

"Zim," Dib said definitely not as a plea, but making sure his voice was more frustrated and firm.

"What is it, Dib-thing?" Zim taunted. "Is there something you want? Why don't you beg for Zim?"

"Gah," Dib laid his head back, but Zim didn't stop his teasing circling movements. Dib tried to shift around, but the restraints on his wrists pulled out tighter and the bands on his ankles locked into place as well, holding him in place. "You jerk," Dib growled out.

Zim chuckled, not at all phased by Dib's insult. Instead of giving Dib what Zim knew he wanted he ran his tongue along Dib's sternum up to his collarbone and traced it to his shoulder. Zim noticed that Dib had shifted his head slightly, most likely in anticipation of Zim traveling up Dib's neck. He knew from research that the neck was another area that was sensitive to touch, which is why he avoided it. Dib was still resisting. Zim wanted dominance. Full dominance over his mating partner's body.

"Human bodies are strange to Zim," he hummed barely able to contain the sadistic glee from his voice. "Dib-thing must inform me on what he would like Zim to do to his body. If you ask nicely, I may feel generous and indulge you," Zim said moving his claws to trace Irken symbols over Dib's chest. Zim had taught Dib basic Irken long ago, but he doubted the human was in any state to concentrate on the letters Zim was writing. It didn't matter, while he waited for Dib to give in he traced his name over and over on Dib's chest. He imagined his name in several places, but still the best spot was the left shoulder, right below the collarbone. On his collarbone there was a scar, one that Zim had caused when they were both much smaller. This one was the largest and stood out the most as it started at his shoulder and dragged across Dib's collarbone.

Zim remembered this one vividly. It had been a nasty fight in the rain. To gain the upperhand Dib had tried to damage Zim's uniform as much as he could. He had managed to take off one of Zim's gloves exposing his skin to the acid-like rain. In retaliation Zim had swiped his claw along Dib's shoulder. His claws were sharp lethal weapons and easily sliced through Dib's clothes and skin. Crying in pain, the boy had relented letting Zim escape. Dib never tried to remove Zim's gloves again.

In truth, if Zim had fought without his gloves Dib would have died long ago. However, the gloves were a part of his invader uniform and he had been told to never remove them. Now that he was a Taller he knew that the reason had nothing to do with the uniform and more to do with the privilege of being a Taller. Only Tallers were allowed the privilege of touch, skin-to-skin touch was something that was done only between mating partners, bonded and non. Smallers had no right to such pleasures, even if it was to defend in battle. The thrill of flesh touching flesh was something only the worthy deserved.

That Dib wanted him when he was a smaller only heightened Zim's pleasure. He vaguely remembered the feeling from that fight, while he had been very focused on surviving the rain and getting back to his base that particular injury had stuck out in his mind. At the time he had felt slightly ashamed that he had to resort to such primitive means to beat Dib, but now Zim relished in that memory. To the Taller him, it solidified the idea that only Dib was fit to be his bonding partner.

Lost as he was in his memories, Zim didn't notice Dib was talking to him at first.

"Damn it, Zim!" Dib growled out through gritted teeth, regaining the Irken's attention. The human's face was flushed and his scent was the perfect combination of arousal and embarrassment. "I said please."

Not willing to admit he hadn't been listening and thus missed the first time Dib had begged for him Zim said in a taunting tone, "Please what?"

"M-more," Dib mumbled, his embarrassment spiking but his arousal doing so as well.

"More what, Dib?" Zim asked feeling triumphant.

"T-Touching," he said not making eye contact with him as his face turned a brighter shade of red.

Zim hummed thoughtfully. "Zim is touching Dib a lot already. Where is Zim not touching that Dib would need to feel more pleasure? Here?" Zim asked moving to lightly trace his claws along Dib's arms. His claws left little white lines in their wake that slowly disappeared.

Dib's breathing increased and Zim felt him shiver. "Damn it, Zim!" Dib swore again. He wouldn't have really wanted his nipples touched in the first place if Zim hadn't been paying so much attention to the area around them, thus drawing Dib's attention to the fact that they were sensitive. He remembered last time when Zim's tongue ran along his chest and neck. Dib remembered kissing Zim and taste of him and he wanted that again. If he was free he would just go in and capture Zim's mouth, or antennae, until Zim threw himself on him, but he was pinned and helpless to satisfy his body's growing needs and completely reliant on Zim.

Dominance. He hadn't really understood what Zim meant. He thought Zim just wanted to top, but it wasn't just that. Zim wanted control. Looking back, when Zim claimed that Dib had won Dib realized that while he had been more in control he hadn't gained full dominance. Just wait until next time , Dib thought. Planning his revenge Dib let his pride take a hit.

"Neck," he said quickly. "N-nipples," he couldn't help the embarrassed stutter. "And kiss me damn it!"

Zim sighed loudly. "Dib-thing. Zim, has gained dominance. You must ask nicely, as the submissive one your only choice is to make requests not demands. Usually, I would be able to punish you, to remind you of who gained dominance, but since you are human and unaware of the mating rules I will let you try again. Now, would Dib like to make a request of Zim?" he said leaning over and grabbing Dib's head so he was forced to make eye contact.

Despite the soft and patient tone, Zim's expression was smug and arrogant. Dib glared at him and was about to retort back, when he remembered about Zim's comment on 'punishment'. The hidden tools on the walls came to mind and Dib swallowed. While his body was clearly telling him and Zim that he didn't hate this little power-play, he wasn't too keen on finding out what Zim's idea of punishment was… at least not yet.

"Please," Dib said and he saw Zim's eyes light up at the word and grow darker with lust. Staring into those eager pools Dib felt his resistance melt away. Zim wanted him. And while it was said teasingly Zim was asking Dib what he wanted. He should be thankful that Zim wasn't just relying on everything he had found online. He should be super thankful as Dib was aware of several kinks that existed. He'd traveled down the rabbit hole on the internet a few times while trying to confirm that his feelings had all been a phase. Some things he never wanted to admit to liking, others had him clicking away as fast as he could.

He couldn't deny, though, that being pinned down and touched by Zim was something that excited him more than being able to elicit those kinds of moans from Zim. Swallowing the saliva that had built up, Dib relented, "Please lick my neck."

"Good," Zim purred and decided to reward the human by doing just that. Leaning down he slid his tongue along Dib's throat and relished in the sounds Dib made in response. There was another reasoning Zim had for making Dib beg. Zim was aware that Dib was hesitant, that there was still some touched-starved sickness within him. He wanted Zim, Zim could tell from his scent yet he was holding back not fully giving himself over. There was still fear mixed with Dib's scent. A small amount that at times leaned more towards nervousness and excitement, which was good, but other times it lingered like a foul smell.

His PAK told him how other Tallers would fix the touch-starved sickness, should it still be at a treatable level. The mating partners usually would win dominance as the sick Taller wouldn't have the capability to hold that position. Zim was doing to Dib what a dominant partner of a sick Taller would do. Complete dominance was very important. In order to help rid of the sickness, the Taller would have to be completely dominated and their control over their own body taken away.

From there it was a delicate balance of getting the sick Taller used to touch, accepting of the sensation, and then making the Taller want more. The begging would assure that the sick Taller would remain submissive making the option of fleeing impossible. However, it was the duty of the partner to do exactly as the other asked. To give the sick Taller the touch their bodies wanted, to slowly give the other control over their body, to give them back their ability to dominate. However, this had to be done without letting the sick Taller aware of what was going on.

To accomplish this, knowledge of how to fix a sick Taller was hidden away in their PAKs. This information only becoming accessible to a Taller's mind if they should encounter such a mating partner. This knowledge came to Zim right after Dib had punched him and revealed that Dib had not adhered to the rules of mating by remaining submissive.

Zim grazed his teeth along Dib's neck, the sharp points of his teeth causing Dib to shudder and gasp. Zim could feel Dib's pulse increase as his tongue flicked along it and up to his jawline. Tracing the under size of Dib's jaw with his tongue he pulled back just as his the tip of his tongue left Dib's chin.

"Kiss me," Dib said his breathing irregular and his eyes heatedly staring at Zim's face, following the movement of Zim's tongue.

Moving closer, Zim paused just out of Dib's reach and stared at him expectantly.

It took a moment, as Dib strained in frustration then he focused on Zim's face and scowled. Zim grinned and Dib relented.

"Please," Dib said and before he could completely finish the word Zim pressed through mouths together. In this he let Dib take the lead as kissing was mostly a human thing. Tallers might lick and bite but this interlocking of tongues wasn't something Zim had been made aware of. However, as they kissed and their tongues slid together in and out of each other's mouth Zim found that this human ritual was one worth continuing in their mating sessions.

"Hands," Dib panted between them. "Let me touch you, please."

Zim was highly tempted. He enjoyed the way Dib's soft fingers trailed over his skin, but in order for this to be successful Zim had to remain dominant. Letting the human have his way in this was a good way for Zim to lose his control.

"No," Zim said pulling back. "Zim will be the one to do the touching. Would you like more touching here?" Zim asked as one claw very lightly grazed Dib's nipple. His spine arched into the touch.

"Yes," Dib hissed.

The sound was close to Irken and Zim chuckled. Deciding to be gracious Zim didn't make Dib beg. He moved his claws to tease and stimulate the senstive spots on Dib's chest. The human swore under his breath as Zim touched him. Slowly the hesitant scent dissipated and a thick scent of arousal filled the air. Zim indulged the human and brought their mouths together again and was pleased at how eagerly Dib responded to him. Dib's treatment was progressing nicely, it was time to go a little farther and prove his dominance over the human once again.

Pulling back, Zim let his claws trail down Dib's chest, across his abdominal muscles to rest at the waistband of his pants. Zim traced small Irken letters that spelt his name on the tight black material over Dib's hip bones. Through the form fitting fabric Zim could tell Dib was responding to his stimulation nicely. Of course, if he wasn't wearing his invader tunic it would have been obvious that Zim was responding to Dib as well.

Wearing the uniform was second nature to him, but in the back of his mind Zim was aware of a bitterness when he thought about his uniform and what meaning it now held for him. He made a mental note to himself to create a new uniform for himself later, one that didn't make him feel like he was being mocked. The more the thought about it, the more the pink tunic displeased him. Not wanting to be distracted by his thoughts Zim stopped touching Dib in order to remove his tunic. Balling it up he threw it across the room and felt both excitement and shame at his mistreatment of the nearly sacred uniform.

"Zim," Dib said his tone causing the ex-invader to look up. His eyes were still heated, but there was an understanding there as well.

As Zim's hands traveled down his body Dib had been captivated by the predatory look in Zim's eyes. When his gaze drifted downwards to the evidence on how Zim was making him feel and the smug look that appeared on Zim face, Dib still couldn't look away. So he immediately noticed when Zim's attention shifted to his own uniform. Zim's face contorted into a pained expression before his brow furrowed and Dib saw his all-too-familiar angry expression. He peeled off his uniform and with a look of disgust threw it across the room. Despite the apparent quick bounce back Zim had from the terrible news, Dib knew that such a betrayal wasn't something easily overcome.

He called out to Zim, wanting to remind the exiled Irken that he wasn't alone that he was there for him. "Screw them, Zim. You're better than them. You're free, you don't have to follow anyone's orders anymore. You can do whatever you want now. You're your own leader now," Dib said with conviction.

Surprise momentarily made Zim's eyes widen as he listened, then he smiled and gazed down at Dib with renewed heat. "Yes, I am," he said and leaned down to bring their mouths together. His long serpentine tongue slipped into Dib's mouth and slid against his tongue before suddenly thrusting deeply down Dib's throat causing him to gag. Dib was immediately worried that this wasn't going to end well, but Zim's hand reached up to tightened around his throat blocking off all air as well as ensuring that nothing came up either.

Despite the uncomfortable and almost painful sensations, Dib couldn't help but react when Zim simultaneously ground his hips against Dib. The squirming sensation Dib felt through Zim's pants only turned him on more. When his lack of air began to draw more of his attention than the feeling of their groins pressed together, Zim released his neck and pulled back leaving Dib gasping and coughing. Dib wanted to protest the treatment but Zim had moved to nip at his throat and a clawed hand slid down to grab him through his pants. Dib gasped and didn't mind the small nicks he could feel from Zim's teeth on his neck. It was going to look like he did a hack job shaving, but Dib didn't mind. Or he didn't mind until he felt an intense and sharp pain as Zim bit down hard on his collarbone.

"OW! Damn-ah, Zim," Dib gritted his teeth and hissed Zim's name. Right after biting him, Zim's hand squeezed him and began stroking him through his pants. Dib could almost feel Zim's tongue along the new wounds and it both irritated the fresh bite mark and soothed it as well. "The hell, Zim?" Dib finally managed to ask.

"I'll mark you properly later," Zim said after one last swipe with his tongue. He leaned forward to hover above Dib's face and grinned down at the scowling human.

"I thought we agreed no pain," Dib said glaring up and trying not to squirm too much as Zim hadn't stopped stroking him.

"I wasn't hurting you-" Zim said and Dib immediately gave him an incredulous look.

"-Like hell you weren't!"

"-I was claiming you," Zim said matter-of-factly over Dib's protest. "Until we bond properly no one else will dare touch you."

Dib blinked once. "No one would anyway!"

"And," Zim added squeezing Dib once before bringing his claws back up to the top of Dib's pants. "It is a reminder to you, Dib-thing, that you belong to me," Zim said as he touched the fresh bite wound on Dib's collarbone.

"Well, you didn't have to choke me," Dib grumbled and ignored the fact his lower half had no problem with the situation.

"I looked it up, lots of human like that," Zim said and moved that hand that was tenderly touched the bite mark to touch the bruises that were forming on Dib's neck. "Your skin is so fragile, there must be some way to improve your durability."

"No thank you," Dib said. "I told you I don't like pain and that includes almost being suffocated."

"Then next time don't reject Zim."

"I wasn't gagging on purpose! It's a reflex," Dib said. "All humans are like that."

Zim gave Dib a stern look. "Do not lie to Zim. I have evidence that plenty of humans do not react that way when using their mouths."

Dib blushed. "Yeah, well they probably have had a lot of practice at that."

Zim hummed thoughtfully. "So it requires practice?"

Dib paled. "No, well... yes, um. Well e-even with practice some people can't stop gagging," Dib said quickly not sure how he felt about the idea.

"Zim liked it," he said stroking Dib's face and slipping his hand into Dib's hair and letting his claws trail along Dib's scalp making the human shiver.

"Y-Yeah?" Dib asked.

"Yes," Zim purred leaning in close. "This kissing is like mating but with tongues."

Dib swallowed thinking about just that.

"Did you not want to do it again?" Zim asked. "Zim wants to."

"Ah, well," Dib swallowed. "Maybe if you go a little slower? And um, no choking."

"Slow?" Zim purred as he sat on top of Dib and shifted just enough to grind their hips together. "You want Zim to slowly invade you?"
