Mating

(I don’t own IZ. ZADR ahead)

Zim sighed The Tallest had denied his request to come home for the mating again it only happened once every year and lasted a month, to be denied was pure torture. Thankfully Zim had learned how to remove the mating hormones; he would be good for a few days before he would have to remove more, he had missed a few days of High skool just to find someway to relive himself of the raging hormones.
Several bottles now sat on the counter top amongst other concoctions. “Now back to my plans” “Ah ha Zim I knew you up to something” “what Dib beast? I meant my plans for the weekend, How many times do I have to tell you My Tallest banished me here and my so called invasion was a joke” “I don’t believe you Zim, I’ll expose you for the alien menace you really are and they’ll stop calling me crazy” Dib tackled Zim, Zim threw him off easily soon a full out fight in sued, finally Zim had enough, using his superior Irken fighting skills he threw Dib over his shoulder, right onto the counter full fragile glass beakers. Dib screamed as glass shards pierced into his flesh and alien chemicals soaked his back, he decided it was a good time to flee the fight. Zim finally left alone was in no mood to clean up he barked at the computer to do so, so he never noticed that the only bottles broken were the ones that contained his hormones.

Dib once again was thankful that his dad was a brilliant scientist who had invented the home medical repair unit, the machine quickly removed all the glass and bandaged him up, he couldn’t think of what he would have to explain to the hospital every time he had gotten hurt when fighting Zim, glass would have been easy but laser burns? He just hoped whatever chemical it was wasn’t harmful to humans.
The next morning he checked the wounds and noticed a strange green rash, it wasn’t itchy or sore so Dib decided to ignore it and re-wrapped the bandages.
Monday had come and the rash had spread across his entire back it still wasn’t bothering him so he decided to go to skool anyways.
It was the usual doom and gloom lessons which he only half paid attention to, as usual he was watching Zim who seemed distracted for some unknown reason
At lunchtime he stood in line for the usual slop which seemed even more unappetizing today taking a bite confirmed it gross, he pushed it away looking around still hungry he wondered if he had time to skip out for a burger, then he caught a whiff of some unusual smell it was enticing he followed it, it came from Zim? Shaking his head he decided to skip out for a burger after all.
Zim had caught his enemy’s weird behavior; he had looked like an Irken following the mating scent, but then he had left the cafeteria weird.
Later heading home Zim tried out a theory Dib was a block away and couldn’t see Zim. Zim let out a croon Dib stopped and let out a similar croon or as similar as the human vocal cords could make. Before Dib could come to investigate where the noise had come from, Zim left he didn’t want his quarry finding out too soon.

Dib had no idea what was happening to him, and why he made that noise after school, he was craving something and he had no idea what, he raced home to find the rash had almost covered his entire body, including his genitals which were looking a bit odd, he raced to his fathers lab to see just what was going on with him, taking a skin sample he pressed it into a analyzer, he then paled he was turning Irken and he had already passed the halfway point, his organs had already changed and the next part was his bone structure if he didn’t find a cure before then he was doomed to become a Irken, he rubbed his hand through his hair only to find it came with his fingers in clumps, he looked at the hair in his hands then he noticed the delicate finger bones were already merging oh no! Too late! He rand to the bathroom to watch as the final changes took place his cranium became square and the rest of his skin became green his brown eyes took a red tinge and then the whites of his eyes disappeared all together two thin stocks replaced his hair, his penis recede into a slit between his legs and his balls disappeared altogether, he hyperventilated he was having a hard time breathing and it wasn’t just because he was panicking.
Zim could help he ran to his room and got dressed pulling a hoodie on and covering his eyes with his prescription sunglasses, when everything went blurry he pulled them off everything came into focus, he didn’t have time t find another pair he ran out into the darkening night hoping no one would see him on the short trip to Zim’s.
He arrived out of breath to find Zim’s door open, not passing up a opportunity he raced inside the main floor was empty, he spotted a box sitting in the middle of the floor with his name on it, out of breath he opened it on the top was a note
“Dib if you wish to live put the pak on and meet me in the woods” Dib pulled the pak out of the box “Irken signature recognized, commencing hookup” it whipped around his backside and burrowed cables into his back sending filaments into every organ and into his brain.
Dib panted finally feeling better for being able to breathe now, went to find Zim

By the time he got to the woods it was pitch black out, even with the better Irken eyes he could barley see, he then caught smell of that enticing aroma he had smelled in the cafeteria he shuddered in the pleasure the smell gave him he crooned, another croon sounded off in the woods, he followed getting lost because the wind had shifted he crooned again. Dib had no idea what had come over him he was craving something badly and it had to do something with Zim, another croon sounded and Dib flowed he found himself in a clearing, suddenly he was to hot for his clothes he took the all off and set them neatly in a pile he sat down on his trench coat and crooned with all his might, suddenly he was surrounded by that enticing smell again his cock slid out of the slit between his legs
“Ah Dib I am glad you accidentally infected yourself with my hormones, I don’t think I could have lasted another mating cycle without another Irken to share it with” “Wait a minute Mating? But we are both boys” “Correction we are both male and female, pure females like Tak are rare” “I don’t want any part of this” “Like you have a choice you are the one who came to me crooning out mating calls, if you leave now you will be back within minutes begging to be mated,”
“well see about that Zim I’m leaving” he got up to leave but the smell hit him again and he let out a involuntary croon Zim came behind up behind him and petted one of his antenna. Dib melted helpless in the lust he was feeling Zim came around to his front and kissed him penetrating his tongue into Dibs mouth wrapping it around Dibs own flexible tongue, Dib moaned and sat back down on his trench coat. Zim parted Dibs legs and felt under Dibs cock into the opening Dib moaned and arched, “yes you are ready” “wait Zim what?” Zim had already pushed himself inside Dib screamed at the new sensation it was pleasurable in the extreme, Zim pounded away until he loosed his seed, Dib was angry his own cock demanded attention and Zim hadn’t even put him to his climax Zim pulled himself out and rolled over onto his back on the rumpled trench coat “What are you waiting for Dib stink I need servicing now” Dib got up and looked at Zim he had his legs spread his own opining waiting for Dibs cock, Dib happily obliged thrusting into the alien with all he had, relishing in the fact that he was now the one getting the alien to scream. Finished he lay down beside Zim.
“There you’ve had your fun now turn me back” “Not until after you’ve laid the smeets, you should turn back naturally” “what? Zim I don’t want to be pregnant!” “Stupid human well not human anymore, what do you think mating is for?” “How am I going to explain that I’m pregnant to My Dad and how are we going to raise the kids?” “We won’t have to the smeet hatcheries will, we just send them the eggs once they are laid in a few weeks, In the meantime I’ll send the Dib bot in you place and I’ll just call in sick no one questions the kid with a skin condition being sick, except you Dib stink if you hadn’t intruded in my lab and landed on a jar of mating hormones you wouldn’t be pregnant now, so stop whining”

Being pregnant was horrible, Dib was bloated constantly hungry and got angry or snively at the littlest things, it didn’t help that he was trapped in Zim’s base who was equally pregnant, finally came the laying Zim had prepared a nest where they both could lay the eggs, it was a smooth bowl with a sand like softness, Dib grunted as the first egg was laid Zim soon deposited a second beside his, Dib found it weird but the laying was exhilarating, soon twenty little green eggs lay in the bowl he hugged Zim and kissed him “I find it weird but I’m glad to have experienced mating with you Zim I’m happy” he went over to the bed prepared and fell asleep but not before he felt Zim curl up beside him “I am happy I mated with you as well Dib” the next morning Zim carefully packaged up the eggs for their trip to the smeet hatchery Dib watched “Will we ever meet them” “not likely” “cant we raise one here” “We don’t have the proper means to keep a smeet alive here Dib I’m sorry I know you species has a attachment to your young but this is how Irkens do it.” Dib then stroked the container containing the eggs “bye then babies grow strong” his hand had already split back into five fingers and his skin was losing it’s green tint, it would be a while before his hair grew back until then he would just wear a hat and claim he lost a bet, it was a weekend so he would go home and replace the Dib bot and catch up on homework

Monday came Early for Zim when he heard an angry pounding on Zim’s door “Zim I need you to answer a question” Zim tore open the door “what is it….” Dib stood there with his cap in his hand two antenna were still on his head “I thought you said I fully return to normal Zim so what the hell is with this” He pointed angrily to the appendages “I never knew, it seems your species is more compatible to Irken mating than I thought, I thought the eggs would be sterile. Once the Tallest find out, I’m sorry Dib but now there is no saving Earth you will all become breeders and you will become more Irken with each mating” “Are you sure you are not mistaken” “Has your pak come off?” “No. oh god Zim, how soon will they find out. When will they be here?”
“They have probably already found out, all off world eggs are checked for fertility, they will be here en mass before next years mating, they will drop hormones upon the populace and they will be as helpless as you were to the mating calls “incoming transmission” come on Dib I had better introduce you as my mate so you don’t become someone’s slave “Ah Zim congratulations on fertile eggs, I’m guessing this is the other egg layer” “Yes this is my mate Dib” “good the fleet is coming in to collect specimens, we are going to induce mating to make sure that the species is really fertile, we expect you and your mate to participate to make sure it’s not a fluke” “Yes my tallest” Dib was running for the door Computer restrain him “No Zim I don’t want to do it again so soon” “What you did not enjoy mating with Zim you lied” “I did enjoy it thouroghly but I don’t want to do it again so soon my body still hurts from the laying, Please Zim” “I’m sorry but I can’t disobey the Tallest”

Dib was kept restrained until the fleet came, he cried when he saw the thousands of ships over the city the military’s jets were no match for the onslaught Dib was among several humans loaded onto a big transport he was glad to see that his Dad and Gaz weren’t on it when it lifted off, his head was bare showing his antenna so the Irken soldiers treated him kindly but his fellow humans heaped scorn upon him for being a traitor, “If you had listened to me years ago about the alien threat we wouldn’t be in this mess” he found a corner near the highest concentration of armed Irkens so he wouldn’t be disturbed.
When he was off loaded he was injected with something and so were the other humans, but he was led down a different corridor and put into a rather nice room, the change happened rather quickly this time sitting on the bed he crooned for Zim, who thankfully didn’t make him wait “The smell of mating is thick on this ship I think things are happening fast because we are still in the mating month” Dib sick of words pounced on Zim this time he wanted top first “Dib have you lost your mind to mating? wait I’m not ready”
Zim pushed him off and slowly kissed Dib taking in his scent, Dib growled he was ready now but he played along soon enough Zim was stripping himself off, Dib wanted him to hurry so he ripped off Zim’s pants and licked the spot between Zim’s legs, Zim moaned “I thought you were the one who didn’t want to mate again so soon” Zim now quite ready parted his legs to receive Dib’s eager thrusting spending himself he rolled over on the bed and found that he craved to be penetrated he spread his legs “Zim please fuck me” Zim slowly complied making his rhythm slow and steady Dib bucked him, wanting something faster “please Zim harder, faster” Zim thankfully complied, Dib screeched his pleasure as Zim filled his cavity. Panting he cuddled up with Zim “I love you don’t ever leave me” I won’t you’re my mate Dib”

This time he was on a ship full of pregnant Irkens which made things a bit easier to take, he wandered over to the holding complex on the massive a big cargo bay had been transformed to house the humans, Dib looked down through a viewing panel the only way he could tell that the pregnant Irkens were human was by their clothing, paks had been installed on everyone of them. Two very tall Irkens came up beside him they too were pregnant “You saved your people you know” “What how?” “the planets we conquer we usually wipe out the native life and use the planet to whatever we need, thankfully for your people we also need breeders, fresh DNA or we get too many defects” “Humanity gets to live even if they will slowly turn into Irkens. Once you are done laying your eggs we will put you into soldier training so you can stay with Zim” “Uh thank you my Tallest, I think its getting close to laying time my belly feels heavy” “Ours too, you and Zim are going to share a laying chamber with us as reward for finding a fertile species, come lets bring into the world the future of the empire”

This time since it was a second mating so close after the first, they only laid five eggs apiece, but the ecstatic feeling was just as great and to share it with the tallest, Dib hadn’t realized that there was a bonding that happened with the laying, he was just as happy to snuggle with the Tallest as he was with Zim,
The humans were forced to lay their eggs in communal pits with the Irkens, they of course bonded with the Irkens, and once they were human again they were released back into the populace to spread the word how great the Irkens were
Dib stayed on the massive with Zim he now looked more Irken than human, the second forced mating had sped up the change, he tapped his green three fingered hand across the keyboard absorbing as much information as he could on Irken mating, it was true when the Irkens found a compatible mating species they treated them well, eventually when the entire populace had fully transformed it was absorbed seamlessly into the Irken empire, however the humans were fighting back they shunned the mated and even actively hurt them the Irkens pulled the mated humans out. But still maintained control over all of Earths airspace

A year later it was time to mate again the air over Earth was filled with mating hormones, thousands of humans rushed to the mating calls, Dib didn’t even notice as he was courting Zim, getting him to be the one to come to him for the mating this time. They were coupling in the same forest as last time it was beyond pleasure even if they had to compete for mating spots Zim went straight for him recognizing his mating scent among the many, a few un mated were crooning to find a transformed human mate. As he was coupling with Zim he noticed one Irken female with a familiar skull necklace and a tall irken in a lab coat and goggles were pairing up with nearby Irkens, Dib felt sorry for them they had no idea why this was happening to them, much like himself a year ago he groaned as Zim hit the sweet spot, thoughts of his family erased from his mind as the pleasure overtook him.
Again they laid eggs with the Tallest this time they filled the bowl up with 60 eggs “A very good breeding species indeed Zim well done and well done Dib” Dib was ecstatic his Tallest was pleased with him Zim was pleased with him and soon all of humanity would be happy.

“Dib you jerk” He had no idea how Gaz recognized him he had Long ago stopped wearing human clothing and wore the uniform of a Irken soldier, and after the last mating he hadn’t transformed back to human in the slightest . His sister still looked quite human aside from green skin and antenna poking out of purple hair “Did you know Dad and I had to lay eggs? Of course he’s fascinated by the science of it all, but we had to do it in public, not like you who gets a private laying chamber with the Almighty Tallest. This is all your fault because you couldn’t keep it in your pants around Zim”
“Gaz I was infected with Irken mating hormones I couldn’t help myself any more than you could, I followed his sent to the woods last year, then I was forced to mate a second time when the armada arrived, I’m sorry but I found out after that the armada had already been on it’s way here to wipe us off the face of the Earth, the only thing that stopped them is Zim and I produced fertile eggs” “I’ll still never forgive you for this DO you know who I got for a mate? Skoodge yuck and to think I have to do it with him again next year”
