Dib jumped back in surprise. "Wh-what do you mean?" he stuttered.
Zim's smirk grew bigger, and he slowly crawled towards Dib. "There is one benefit to being 'defective'~"
Dib continued to crawl backwards as Zim was practically on his lap.
"All sexuality has been programmed out of modern Irkens, but traces still show up in defectives. I've never properly explored it myself, we can try it together if you want~"
Dib's face went completely red. "You- you have-"
"I was always ashamed of it," Zim interrupted. "But you humans have some…interesting ideas~" he said with a smirk.
Before Dib could reply, Zim extended his pak legs and scooped Dib up. He was surprisingly strong.
"W-wait what are you-" Dib stammered.
"Back to my lab," Zim interrupted. "I'm looking forward to experimenting with you more, Dib-mate~"
Dib struggled to stifle his whimper, though he'd be lying if he said he didn't want this too.
Zim quickly scurried with Dib back to his base, not bothering to put hos disguise back on.
Zim continued to carry Dib down to his lab. He pressed a button which opened sliding doors revealing a dimly lit room with a large circular magenta bed in the middle.
"I-I thought Irkens didn't need sleep?" Dib stammered.
"Zim looked away in embarrassment. "Eh, defectives do, occasionally."
Zim tossed Dib onto the bed and quickly got on top of him. He pressed another button which closed the doors, now only leaving them in dim pink lighting.
Dib shuddered as a claw traced his chest and grabbed onto his tie. "Come on~" Zim sneered. "Don't make me do all the work."
Dib gulped, taking off his jacket and unbuttoning his dress shirt.
Once Dib's top half was nothing more than a loose tie, Zim yanked Dib's pants off in one fell swoop with a wicked grin, and Dib's erection sprang up.
"You're disgusting," Zim sneered. "Already so desperate and wanting for Zim~"
Dib whimpered, as Zim started to remove his black leggings, revealing a slit between his legs.
Dib watched in awe as the slit opened up to reveal a large tentacle, similar to the irkens tongue, but seemed to be more textured.
Zim leaned forward and caught Dib in another kiss, his long worm like tongue exploring his mouth and throat, while the tentacle started to coil around Dib's member.
Dib could only continue to groan and whimper, as Zim sank down onto him. His vent was wet and tight, its walls textured.
Zim pulled away to remove the rest of his uniform. He was skinny, but had a little muscle on him, which Dib figured shouldn't come as a surprise. Dib rested his hands on Zim's waist, and stared up at his beautiful magenta eyes, which from here looked like entire galaxies. Dib could've sworn Zim's eyes were adding extra pink light to the already extremely pink room.
Zim planted his hands on Dib's chest, right below his shoulders, and began to move.
"Ah- Zim~" Dib groaned.
"Yess~" Zim hissed. "Say my name, Dib-pet! Tell me who you belong to!" He grabbed Dib's tie and tugged on it as if it were a leash.
Dib was too lost in pleasure to combat the degrading words. He just continued to let Zim ride him, gradually increasing his pace.
Dib stared at the tentacle sliding up and down his cock. "Zim- I-" he stammered.
"Yes~ praise your master!" Zim exclaimed.
"Zim I wa- I want you inside me!" Dib blurted out.
Zim slowed his movements, and slid off of Dib's erection. He stared at Dib with a wicked grin as Dib wondered if he'd just made a huge mistake.
Zim lifted Dib's legs and slid his tentacle against his entrance, coating it in slick and causing Dib to whine.
With a smirk, Zim shoved his tentacle inside Dib, causing the human to cry out in pleasure. Zim's tentacle almost felt like jelly, with ridges and bumps along the sides as to not let it slip out too easily.
Dib continued to cry out as Zim slammed into him with the force of an alien soldier, the base of his tentacle stretching him out while the tapered end continued to hit his prostate repeatedly.
Finally, Dib came with one final cry, but Zim continued a bit longer until he came inside Dib, causing him to whimper.
Zim collapsed onto Dib's chest, both of them panting with exhaustion as they tried to ride out the afterglow.
"Zim.." Dib breathed. "You wanna just…forget earth and go explore space together?"
"I think..I think I'd like that," Zim replied.
