Dibblet smirked as he stood in front of the elevator. Yes, he had been running for at least a good ten minutes. The hallways felt like they would go on forever but he didn't have the luxury of giving up. Zim was hot on his heels.

"Dib-Scum! I know you're around here! You cannot hide from ZIM!" The human quietly snickered as he stepped into the elevator. He slid down the wall. His thighs burned from running so quickly and without rest. A small "ding" went off and the human found himself being forcefully thrown out of the elevator.

"Ow." The paranormal investigator stated as he rubbed his head. He curiously looked around the medium space which seemed to be a walk-in closet. It was mildly cramped, there were two sides of the closet which reflected the personalities of their owners. On the left there was a multitude of different single color cotton T-shirts with different slogans and designs. There were no printed fabric shirts among them. There were five long black trench coats made of different material. Dibblet carefully ran the tips of his fingers over one of them. It was black leather. The thirteen year old could only imagine how expensive it had cost. Underneath the hanging clothes there was a row of black combat boots and sneakers.

There was a set of drawers beside the hangers. The human carefully pulled one open to see that they were filled with folded up black pants and jeans. The second set from the bottom was filled with accessories, things like fingerless gloves and the like. The third drawer was filled with socks and boxers. For a second Dib could admit feeling slightly jealous of his future self for the wardrobe. The human frantically shook his head. There was nothing that his future self had gained that was worth getting envious over.

He looked over to the right side and saw that Zim's clothes were a bit more varied. They all were made with that strange slightly rubbery yet silky fabric that all of his clothes seem to have but they weren't all the same like from the Zim from his time. The cuts resembled a human shirt and now there were many different colors, but pink and green still seemed to be the same color scheme. There were a few pairs of boots under the clothes but aside from the shirts and silver pants the older Zim seemed to have significantly less clothes that his human counterpart. Suddenly there was a bump at the door. Dib immediately crouched down to hide, he slowly tiptoed to the door. He heard cries outside the door that sounded similarly close to his own.

Adrenaline rose in the thirteen year old as he carefully cracked the door. His eyes widened as he watched the older version of Zim and the older version of himself exchange blows. The tall alien was sporting quite a few bruises but for every bruise that the alien had the human had at least two.

The two ran at each other again but Zim grabbed Dib's hand in mid-punch.

"You need to give it up Dib-Pet, you are nowhere near topping me." The older alien calmly stated as he pulled his mate to him. Two sets of lips frantically met each other. Dib moved his hands to the top of his Master's head and began to gently caress the lekku there. He felt an immense sense of satisfaction as he felt his Owner shiver. Sharp teeth gently nipped his Pet's lips, and a small drop of blood came between them. Dib could only moan in pleasure. In his world, pain and pleasure had been intertwined for so long he doubted he could tell the difference any more. A gasp exited him as his ass was roughly grabbed, sending him closer to his Master. This seemed to signal a new battle. The two crashed into a wall, Zim easily lifted his pet up and grinded against him. A needy whine exited the human as he wrapped his legs around the alien's waist. Zim effortlessly tore off the shirt that his Dib-Pet was wearing. The human leaned his head back into the wall. The Irkan took advantage of this and began to gently nibble on the exposed skin. Din scratched down his Master's back as he gave him more room.

The human was then roughly thrown on the bed in the middle of the room. In no time at all Zim was in front of him, carelessly pulling off the boxers. Dib shivered as he felt those three fingered hands touching him. One hand forcefully held down his hips and the other calmly stroked up and down the human's weeping length. A smirk rose to the alien's face.

"You are such a slut Dib-Mate. I bet you are wanting me right now. Wouldn't you be so happy with sucking my cock, Dib-Pet? Hmm? Answer me!" The Irkan invader commanded as the hand that was stroking the slave's shaft tightened. Dib arched up at the sensation.

"Yes, Master." Dib breathlessly answered.

"Beg, Dib-Slut."

"Please Master. Please let me suck your cock like the cock sucker I am." The human begged as he looked at his Owner. A satisfied smirk came over Zim's face and creepily enough his magenta eyes took on a loving tone.

"All you had to do was ask, Dib-Pet." The Irkan unzipped his pants letting his member free. The human laid still as his Master straddled his face and began thrusting in and out of his mouth. His hands dug into his Pet's hair. He twirled the scythe strip of hair in his hand and he used it to gain leverage in this position. The other hand was wrapped around the cock of his slave, not letting him come despite how hard the member was.

The sexual arousal was nearly too much for the human to take. His body ached pleasantly. His mouth was full as his tongue wrapped around the shaft of his Master. He purred to send the vibrations throughout the appendage. A small gasp was heard from above him which he soon mimicked as his hair was pulled in pleasure.

"Stop…Dib-Mate." The alien breathlessly ordered. The suction around his cock immediately ceased. Zim quickly got off the bed and kicked off his own pants. His human watched the taller one with lust in his eyes. Dib gasped as his ankles were grabbed within the alien's hands and he was pulled to the edge of the bed. Zim stroked his organ as his pet obediently laid back on his back and lifted his legs. The Irkan's cock looked similar to a human's penis except there was no scrotum and the penis looked like it had a slightly bumpy texture.

Zim took no more time waiting as he hooked his Mate's legs over his shoulders and began to stretch the bottoming human.

"Remember Dib-Pet, If you cum before I tell you, you will be punished." Zim purred as he made sure to his the prostate directly with his fingers. Dib let out a small whine from the pleasure overload. He made sure to hook his ankles around the Irkan's head in an attempt to hold off the orgasm. He grabbed the headboard on the bed to attempt to focus on it but it was a futile effort. This pleasure haze of preparing continued for a few minutes. Zim bided his time by using his other hand to make small cuts and light scratches onto his Slave's stomach. His Dib was such a masochist but he supposed that was his own fault.

By the time he had finally put it in his Pet was whimpering, thrashing, moaning, and desperately trying to keep control. This was Zim's favorite part. This was when his Dib-Mate looked the most beautiful. The way his cheeks were flushed, sweat clinging to his brow, how he was so desperately trying to please him, the way his ownership tattoos shone clearly on that healthy yet pale skin. It made the Irkan so hard with pure want.

The thrusting began and as before Zim showed no mercy. It seemed to go on forever for Dib who was trying with all of his might not to cum. The last time he had made a mistake he had been chained down to underneath his Master's work desk for a whole day forced to give a constant blowjob. His jaw had never ached so badly! Dib's body rocked with the hard, frantic thrusts of the taller being above him. He could tell just by the pace that his Owner would be over soon.

"Cum for me Dib-Slut." Zim lustfully ordered. Dib arched back as he felt the earth shattering orgasm overcome him. The pain swam through him as his Owner's claws tore into his shoulders from the impact of his own orgasm. Zim let his Pet milk him for all he was worth before withdrawing. He looked down to the exhausted, slightly bloody, cum covered body of his former enemy under him and he couldn't help but feel pride. Dib was HIS.

"Are you alright Dib-Pet?" The human gave a sleepy look into those magenta eyes before nodding.

"Alright, then don't stink up my quarters. Take a shower and have the computer give you medical attention." Dib let out a yawn.

"Ok, are you coming?"

"Yes, I'll get one after you."

Dibblet watched the whole thing with wide eyes. No! This couldn't be happening. Ok, he could deal with his future self being a slave to Zim. He certainly wasn't happy about it but he could deal with it, yet what he just saw blew everything he had thought about this future to hell. It was only made worse with the arrival of an alien his own age.

"Ha! I found you Dib-Stink! You thought that you could hide from the ALMIGHTY ZIM but you were wrong Dib-Monkey!" The alien screamed as he aggressively pointed at the human, slowly stalking him. It was this movement which triggered that mental breakdown which had been waiting to happen for years.

"!" With that scream the Dibblet ran from the closet, down the stairs, and into the outside world. The older version of Zim watched with confusion as a screaming black streak ran from his closet.

"Is something going on out there? I thought I heard something!" The future version of Dib yelled from the bathroom. The alien rolled his eyes as he stalked inside the closet and grabbed his younger counterpart.

"Something you can take care of later, Dib-Pet, nothing to worry about now!" Zim yelled back.

"You on the other hand are coming with me." He growled at his younger version as he grabbed the smaller one's arms and pulled him into one of the deeper labs.
