LABORATORY RATS

Rated: Mature for later chapters

NOTE: This is a story that takes forever to finish, so the first couple of chapters are sometimes very cringey cause they've been written a couple years back (not to mention bad English, it's not my first language). The chapters get better as they go along!

DIB

It was a Thursday night. A beautiful one, actually. The sun was about to disappear, yet it's remains created beautiful, red patterns in the clouds. However, Dib and his companion couldn't enjoy them, as they were miles underground. Separated from the night's sky, yet safely in Zim's base.

Dib made his way through the halls, only dressed in some boxer shorts. While walking, he made well-intentioned attempts to dry his soaking, black hairs, ruffling through them with a white blanket. With his elbows, he pushed the door open to the bedroom. After some more ruffling, he looked up to see a green, petite alien sitting on the bed.

He too, wasn't wearing much. Dib's own long sleeved shirt lazily hung around his shoulders. You couldn't really call it 'wearing', as the piece of clothing was easily 5 sizes too big. He wore simple, black knickers and his legs ended in some black socks, keeping the fragile claws from getting too cold. He was flipping through a magazine – to kill time, no doubt - and looked up as Dib came in.

'That took you long enough.' He snarled. He threw the magazine aside. When it landed on the carpet, Dib recognized it as one of his own magazines about the paranormal.

'Keep your hands off my stuff.' Came the reply. It hadn't sounded angry or upset, not even serious. Dib knew that Zim does whatever he wants. Most of the time, telling him not to do something just encourages him.

Dib fell forward onto the bed after giving up on drying his hair. He caught a disgusted look from the alien while he looked at his damp hair. After all those years, water still was feared for the acid-like response Zim's skin had on it. Dib ignored it and nuzzled the pillow, getting comfortable.

A few seconds later, he felt Zim moving on the bed, crawling towards him. Dib turned his head to look up and saw Zim's annoyed, scrunchy face.

'What is it?' Dib said, smiling. He lazily started turning onto his back, sighing in the progress as the tension in his muscles left. His body felt tired after a long day at work.

'Pay attention to me.' Zim sneered, not breaking eye contact while getting on top of the human, his legs both on one side of the human's pale hips. He placed his claws on his shoulders, mindful of the wet hair plucks.

Dib snickered. 'You'd think I can ignore if you do this?' he said, to which Zim responded with a shrug. Dib placed his right hand on Zim's cheek.

Zim's anger disappeared and the small body seemed to melt at the touch. He sighed and Dib felt the green legs and hips relax. Dib smiled content and then moved his hand in Zim's neck, pulling him downward.

Zim managed to give a small chuckle before their lips met. Instantly, they opened. Automatically, they tilt their heads at the same moment to get better access to each other's mouths. Dib rubbed up and down Zim's small body, starting at his shoulders, down his back to his hips and back. Zim smiled in the kiss while their tongues made a slow, sensual dance around each other. Not too fast, not too slow, just perfect.

From Zim's needy sighs and the way he clung to his shoulders Dib concluded he was in the mood, so he didn't hesitate to slip his hands inside of his underwear, resting them on his small butt . The cold hands seemed to surprise Zim because he yelped quietly, the contact between their lips breaking for a second. Dib laughed and after a mumbled 'come here..' he devoured his lips again.

They were just getting into it when a metallic voice interrupted the make out.

'Ehr... Master..' Zim's computer said. Dib felt Zim's body tense in irritation, but he ignored it, and so did Dib. He knew there was no point in trying to ignore the voice. There was something wrong (or right), and the master of the house needed to know, now.

So, as expected, the house tried again after a few seconds.

'Master, may I just.. There's a transmission..'

'uuRRRGH WHAT!?' Zim screamed, sitting up. His claws buried themselves in Dib's shoulders in anger and Dib shuddered. He couldn't suppress a smile, though. A pissed Zim didn't get old.

'This better be IMPORTANT!' His lover screeched to the ceiling, as if the computer had a face, and it was right above them. During the conversation however, he kept spinning his head from wall to wall.

'It is.' The voice said. 'There's a transmission.'

'Nobody's important enough to-' Zim started.

'The Almighty Tallest are.' His computer interrupted.

Zim gasped and froze, his antennae jumping up. He didn't move for a few seconds.

'..The Tallests are calling?' He asked in a trembling voice, from fear or excitement, it was hard to tell.

'Yes, they are. I'd hurry up if I were you. You don't want to keep them waiting.'

A few more seconds of Zim processing the information passed, before Zim jumped off of Dib with a shriek. He seemed to have forgotten his lover and their actions from before, as he screamed and trashed around to find his uniform.

'The Tallest! A transmission! They're the first ones to call! They're calling ME!'

Dib's tired ears protested to the noise. He covered them with his palms, but got up from the bed while Zim struggled to get into his pink clothes.

When Zim's head popped out of the shirt's hole, Dib grabbed his shoulders to keep him still for a while.

'Can I come?' He asked. He figured he should ask his question straight forward. Zim didn't have time for a lecture.

'What? NO!' Zim screeched. He seemed both overjoyed and really nervous. His pink orbs scanned over Dib's half naked body.

'No! Of course not!'

Dib thought quickly. 'I.. I can change into a suit?'

'Formal attire won't change the size of your head, Dib.' Came the rude reply.

'Oh come on, I won't be seen..'

'No. Out of my way.' Zim pushed him aside with a strenght betraying his size. Dib fell back on the bed and propped himself up on his elbows to see Zim had disappeared.

Dib opened his mouth to shout something, but closed it again. He couldn't find any words while he heard Zim's impatient jumping-up-and-down before the elevator arrived.

He wondered what this was all about, and what the consequences would be. A transmission from the Tallest themselves, that was a huge deal. Dib flopped down in the sheets. Some fear flowed through him, what if they ordered Zim to leave earth and conquer another planet? What if they were planning to blow up earth tomorrow, and they were calling to tell him to get the hell out of here? He sighed and then collected the sheets to throw them over himself.

He'll just have to wait.
