[A/N: this isn't related to my other IZ fics. This is definitely gonna be sensual, but not as intense as some other d/s fics i've done. So we'll say that they're the same age here, yes? Character is from comic issue 9. More info at end notes.

TW/CW: riding in a vehicle, power dynamics, nerves, praise, flirting, touching, kissing, nonverbal consent, might be read as coercion/entrapment but i didn't intend that (it's completely wanted by both sides)]

Zim thought his new "intern" slave was doing pretty good. Well, maybe not as 'good' as he may have wanted, but good enough. If nothing else, he was doing what was asked of him without any resistance, which was a pleasant change of pace from his robotic slaves. That alone made this Derb guy somebody that Zim was a lot more trusting of.

In fact, it almost made him like the guy. Sure, he still had plenty to learn, but Zim was certain that he would make an excellent invader of Derb yet! Who better to teach an up-and-coming conqueror than one so mighty and wondrous as ZIIIM?! No one, that's who!

There was something that drew Zim to Derb: enough to reward his work by showing him one of his favorite secret places to go. He took Derb to a tiny galaxy, where everything was the perfect size to squish and squash and destroy. He knew that even someone as pitiful as his intern would be able to wreak some havoc here, and he was happy to encourage him to do so. It was great to see him take his first real steps to becoming a ruthless invader! It made his squeedlyspooch feel all tingly inside.

A little while after they began the journey back to Earth, Zim decided to make conversation. "You know, Slave Derb…" He could feel Derb turn to him, and he suddenly felt somewhat nervous. "I really think that you have a lot of potential. Zim can tell that you will be an excellent invader some day." He smirked at him. "With Zim's guidance, of course."

Derb seemed surprised. "R-really???" He didn't think that Zim was able to feel that way, much less express it. "Th… thank you, Master Zim…"

Zim smiled and nodded. He turned back to the controls of the Voot Cruiser and started pressing some buttons. 'You are very good at following directions. Your leaders will be very proud of the things that you have learned by working for the mighty Zim."

Derb shyly smiled. "Thank you, Sir."

"I knew from the moment i saw you that you were special." He glanced over, and his heart fluttered a bit at his worker. "There's something about you that just screams…" He glanced around the cockpit's ceiling for the right wording. He grunted, but couldn't come up with anything. "Er, ah, well anyway," he waved his hand, dismissing the thought.

Zim looked over the settings for the Voot again, making sure that the autopilot was properly engaged before he decided for or against taking the gamble that was calling him. He quickly weighed the pros and cons.

"Zim also thinks…" His throat caught, but he was going to say it anyway. "Derb is really cute."

"What?!" He felt like he had to be imagining things. "You think i'm c-cute?!"

They locked eyes. "Y-yes. Very cute! I like your big, round glasses and your little button nose."

Derb tensed to himself, but thinking about what Zim said made him blush. "Y-you do???"

"I do." He stood up beside his seat. "Your ears are so cute when they get droopy," Zim stepped closer to him, and Derb took a step back. "And i love how your adorable little teeth peek out when you smile…" Zim huffed and blushed between thoughts. "I-it makes me feel happy, i must say…"

Derb glanced around nervously, processing what Zim was saying and how he was acting. He had never seen him act like this before, and while that was somewhat uncomfortable for him, it was also really endearing. His chest tightened and his face got hot when he thought about the application of what he was saying.

"And that…" He stepped even closer, but Derb had nowhere left to hide. "Fin… on your head is…" He pushed himself against the wall of the Voot to make himself small. Zim lifted his hand, "soo alluriiinngg." He delicately touched his palm to the protrusion and carressed it.

Derb's face was burning, and his breathing was shallow. He watched Zim turn his vision down to him with a smile he never thought could be on that face. He didn't see Zim's other hand come up beside him, but felt him gently brush his hand against his cheek.

Derb was more nervous than ever, but feeling Zim's thumb graze his skin helped calm him down a bit. Zim lowered his hand to his shoulder, and Derb shyly looked up at him. "Your eyes are so beautiful…" He watched the mouth that said that slowly come closer to his own, seemingly cautious for if Derb said that he didn't want to.

But he did want to, and he knew that even more so when Zim's soft lips connected with his own. He felt a wave of affection rush over his whole body. Derb had never kissed anyone before, but it felt like Zim knew exactly what to do. After a few seconds of this lovely touching, the two locked lidded eyes again. "Z-zim…"

He moved his palm along his jaw and barely tapped his thumb on Derb's lip. "Do you want to sit down???" Zim stepped aside and offered his captain's chair with his hand. "Go on," Derb breathed. "Have a seat."

Derb glanced at Zim and thought about the situation. He knew that he had been feeling attracted to Zim for a while now, but he never thought he would be getting intimate with him like this. He thought about what would come of this, and he thought about how irresponsible it was to get roped into getting even further into this than he was right now. Still, Derb really did want to feel Zim touch him again, and he didn't want to squander the opportunity if it would completely disappear beyond this.

Derb quivered. He breathed in deeply and made his decision. He stepped to the chair and sat as he was told. Zim grinned and followed behind, slipping his hand to the side of the chair to adjust it. In an instant, the back of the seat fell halfway down and was pushed away from the controls a bit. Derb squeaked in surprise, and Zim smirked. "Comfortable??"

"Um!" He quickly studied Zim's flirty expression, completely uncertain as to what was going to happen next. He flinched when he saw Zim lean forward again.

"Don't worry your pretty lumpy head, Derby. Your Great Master Zim will take very good care of you." Zim crooned as he tossed half of his body up over Derb, supported by hands next to his shoulders and a knee between Derb's. He tensed again as Zim lowered his head to tenderly kiss him again, staying against him for longer than he did before.

Zim released him to a peaceful sigh against his lips. He gazed into Derb's dreamy eyes watching him, and he smiled in response. He came closer again, kissing his cheek softly and slowly beginning a path. He pecked his chin, and Derb gasped when he felt Zim's lips caress his throat.

Zim kissed every centimeter down Derb's neck, holding each touch for a small while every time. Derb peeped and tried to concentrate on his breathing, but he knew he was getting desperate for Zim's affection. He gripped his hands tightly on the seat beneath to try and keep control.

When Zim finally reached his collarbone, he used one of his hands to push Derb's shirt out of the way. He kissed all over the top of his chest, tickling under his bones and on flesh that became more sensitive. Zim couldn't help but brush his skin at the same time, responding to Derb's squeaking and twitches with a couple hums and moans. He opened one eye to watch his reactions, grinning to himself at how delicious he looked.

Zim felt Derb's heart pounding under his lips. He glanced over him and moved his other hand to touch Derb's side, gaining a little whimper as soon as he made contact. Zim leaned down again and opened his mouth to lick over the places that he marked before. Derb clenched his eyes and teeth and gripped the seat harder, loving how Zim's tongue felt on his skin.

Zim snaked all over where he had kissed, leaving a hot, wet path up and down Derb's throat. He pet him where he was, hoping to get him pining for more.

Derb shook and whined. He loved the feeling of Zim on him, but he desperately wanted more. He hoped that Zim was feeling extra generous as he decided to speak. He sighed in a shallow breath. "Ziiimmm…"

Zim chuckled out of his open mouth. "Yeesss???" He lightly kissed the damp skin.

"P-please touch me more, M-Master…" Derb twitched with every new kiss.

"Is that all that you want???" Zim tilted his nose up against his chin and slowly flicked his tongue over Derb's jawline. He rubbed his hands all along his body, reveling in the needy groans that he got.

"M-may i touch you, as well, Sir???" He hoped he'd be allowed to return some of the contact.

"Hmmm…" Zim pretended to consider. He kissed a few times down Derb's shaky throat and at the top of his chest. He rubbed his hands up and down a few times over and hummed slowly, trying to make Derb whine some more before he gave an answer. "You maaayyy."

Derb paused for a second, then raised his arms as fast as he could to get his hands all over Zim. He whimpered "thank you, Master."

Zim chuckled as he watched Derb start to explore him. He grinned wide when he saw him bite his lip, and gave him a sly, flirty smirk when Derb turned his eyes to meet his. "Why don't you show me how thankful you are??"

Derb whined and bit his lip again, fully knowing what he wanted to do to Zim. He swiped his hands quickly up his body, holding him by the shoulder and behind his head and pulling him close to kiss with all of their mouths. He moaned and whined as their lips locked together, and Zim laughed as their tongues intertwined.

Derb moved his hand down Zim's body, pulling him closer as he raised his knees. Zim complied, slipping the arm that he leaned on underneath Derb to return the embrace. He rubbed his other hand all along Derb's body, making him moan enough to open his mouth. "Heheh, you're such a good boy, Derb."

Derb blushed hard as he whined and turned his head away, unconsciously pulling his knees closer together, which made them touch Zim's body. He grinned and chuckled at the response, happy to have hit such a sensitive spot with just a few words. Zim kissed and licked his pet's neck again, staying longer in some spots than he did before. "Z-ziimmm…"

He continued to suck on one spot for a few more agonizing seconds. "Yes, my slave???"

"You make me feel so good, Master." Derb pulled at Zim on the other side of his body and lifted a hand to tease tiny touches along his antennae.

Zim growled happily, resting his hips on Derb's lap. He kissed and licked his throat more fervently, moaning with each affection. Derb sighed and whined the whole time, holding Zim close against his body and desperately touching him everywhere he could make contact. "Oooohhhh Masteeerrrr…"

Zim felt a spring in himself when he heard him speak. He grinned and pressed his whole body against Derb's. He tangled their legs together and glued their mouths to be one: both lovers sucking in hot need and voice as much as they could. They fought with their lips and their tongues, passionately moaning and sighing and gasping when they could, so overcome with the feeling that they forgot everything else.

Derb pulled Zim close as he continued to touch him everywhere. He no longer cared what it meant, or what would happen after this. All that mattered to him now was the weight on his chest and the feeling in his mouth. He intended to savor every last second of this heaven, having waited for this for an unbearable eternity that he hadn't recognized until only a few minutes ago. There wasn't much that could make this better for him. "S-such…" Sighing and panting in between the heaf. "Suuuch a good boy, Derb…"

It drove him wild. He pinned Zim to him as close as he could, wrapping him up with his legs and his arms so tightly that Zim had to push himself up against the seat with his hand and elbow. Derb pulled his lips away to grip onto Zim's throat until he fully understood what those words did to him. He sucked and licked and kissed his soft skin with such intensity that it startled Zim. He nervously chuckled. "Z-zim guesses you really like that, huh???"

Dedb moaned, and whispered quietly against his skin. "Shush shh shh, Master, please." He smothered his face again.

Zim twitched and smirked. "You dare tell Zim what to do?!"

Derb didn't separate again: he just hummed directly onto Zim's voicebox. The vibration sent a tingle all the way up Zim's body, making him quiver and sigh with a huge smile on his face. "O-o-ohhh. O-okay." He closed his eyes tight and grinned as he tried to endure the feeling. He didn't think he'd be so okay with receiving instructions like that, but he found that he really didn't care right now.

Nothing could have ruined the moment more. "Proximity warning."

They grew attentive for only a second before separating as quickly as they could. Derb adjusted his clothes and his glasses, and Zim went back to the controls to land the vessel. He smoothly brought it down into the hangar as if he had been flying it the whole time.

Right after initiating the shutdown procedure, Zim glanced over to Derb. He noticed that his glasses were smudged up pretty badly, so he grabbed them and rubbed the lenses clean with the bottom of his tunic. He quickly and carefully placed them back on Derb's surprised face. He blinked, and just before the Voot's hatch opened, he planted a little kiss on Zim's cheek, making him smile.

[Post A/N: in issue 9 of the comic, Dib disguises himself as an alien intern (Derb) to get into Zim's lab to spy on him. This fic happens after Zim takss Derb to a secret place where he destroys tiny planets lmao.

Sorry if the ending sucks. :p]
