"OMG OMG OMG. This is so bad!" Dib said to himself as he rushed to his office.

"Dib, wait!" Zim called from down the hall, following.

"Don't call me by my first name! I'm Dr. Membrane to you!" He yelled and picked up his pace. He heard Zim laugh far behind him and turned to look, but suddenly Zim was right next to him.

"We're beyond such formalities now, don't you think?" Zim said.

Dib blinked in surprise then sped up even more, just about jogging passed the lockers now. "This isn't funny, Zim. Why didn't you tell me you were a high school student? One of MY students!"

"I forgot you were my teacher – I don't come to school very much." Zim said, easily keeping pace with Dib even though his legs were so much shorter. "And I never pay attention. Why didn't you recognize me? I'm the only green person in town."

"It was dark, I couldn't tell you had green skin!" Dib replied quickly. "And those weird purple eyes!"

"Well, I told you I'm 16." Zim retorted, a little insulted by Dib calling his eyes 'weird'.

Dib stopped. "You said you were 18!" He yelled, then realized he was still at school and made sure the hallway was still empty – however there were lessons going on behind closed doors. "I thought when you said you were 16 it was just . . . you . . . role playing!" He whispered.

"Strange role for me to play." Zim said. "So does that mean your role was the creepy old pedophile?"

Dib gave him a dirty look then took the last few steps into his office. "Just go back to class! Last night never happened! It can't have happened!" He insisted and slammed the door closed.

"Why?" Zim said to him through the locked door. "I felt a connection to you and I know you felt one with me." Zim didn't know it but on the other side of the door Dib was sitting at his desk with his hands on his head again – trying to keep himself from panicking.

"Zim, be quiet! There are people –"

"So what if you're my teacher?" Zim's voice said from right behind Dib. Dib jumped up and backed away from his desk – Zim was sitting on the window sill. "I won't tell anyone."

"High school teacher, Zim! High school!" Dib yelled back. "You're a minor! I would never have done that with you if I knew - how did you get through the window so fast? This is the second floor."

"You're . . . dumping me?" Zim interrupted, looking sincerely upset.

"We were never together, how can I dump someone I'm not even in a relationship with?" Dib said. "I can't work here anymore. Zim, please just go back to class and let me figure out what I'm going to do."

"There's no class to go back to; everyone left when you walked out." Zim answered tersely. "And where I come from 16 is considered adult."

"Oh right, where are you from? Uganda?" Dib replied, not believing him.

"No." Zim answered simply, not hearing the sarcasm in Dib's words. "Where's that?"

"It's in Africa, Zim." Dib answered, exasperated. He took off his glasses and rubbed his eyes.

Zim realized then how truly distraught his teacher was and felt sympathy for him. "I'm older than you think." Zim said, ready to tell Dib the truth about his origins if only it would make him feel better. "So you don't need to worry so much."

"I know exactly how old you are." Dib replied. "You're 2 years too young."

"I am here, but in Irken years I'm –"

"'Irken years'?" Dib interrupted, finally looking at Zim again. "Is that one of those stupid 'henway' jokes? This really isn't a good time for joking, Zim. This is serious."

"What's a 'henway'?" Zim asked, confused.

"About two pounds." Dib answered but he wasn't laughing.

Zim blinked, he no idea what Dib was talking about but he at least he was calming down. "Dib, I don't want to explain it but I promise you that I have been alive for more than 16 years." Zim said and approached Dib. He brought his face very close to the older man's, ghosting a sweet kiss on Dib's mouth.

Dib didn't pull away, he looked deep into Zim's eyes. "That doesn't make any sense." He said quietly. Zim kissed his mouth again, this time a little firmer but still gently. Dib found himself kissing Zim back without even meaning to and his breathing sped up. Zim smiled but didn't stop, he pushed Dib back onto his desk and positioned himself between Dib's legs.

"You still want me, right?" Zim asked, pressing his body against Dib's like he had on the dance floor.

Dib just looked at him. He didn't want to answer for fear of what he would say and what it would mean. "I don't know . . . " He finally answered.

Zim pushed him back onto the desk and climbed over top of him. "You do." He corrected. "It's okay, you can say it." Zim then unbuttoned Dib's shirt and spread it open. He leaned down and ran his tongue along Dib's collar bone. "Tell me you want me." Zim said and kissed Dib's neck a few times.

"Uh . . . I can't think straight with you doing that." Dib whispered but he pulled Zim's shirt off over his head.

"You don't need to think, your body is more honest anyway." Zim said and sat down on Dib's thighs. He unzipped his own pants and pulled his cock out, stroking it a little for Dib to see.

"What are you?" Dib asked, watching a bluish fluid drip out of Zim's dick and run down his hand while he rubbed himself. His dick wasn't like a man's usually is; it was longer and thinner, and curved to a point instead of a helmet-shape. Also it was purple and ribbed.

"Just an ordinary high school student." Zim answered, rocking his hips when he felt Dib become hard underneath him.

"No, not ordinary." Dib said when Zim lifted himself up and opened his pants. Dib's cock was painfully hard and popped out readily. Zim positioned himself above it then sat down slowly, taking it all the way inside of him. "Remember? You're special."

Zim smiled, looking shyly to the side as he began to move his body back and forth. Dib sighed happily and put his hands on Zim's butt, helping him move. He rocked his hips in time with Zim's slowly.

After a few minutes of slow and intimate love making the school bell rang. Zim sat up and watched the students file out of the classes into the quad through the window. He didn't stop moving, in fact he sped up his pace. "Hey Dib, if anyone were to look up they can easily see me through the window." He looked down at Dib mischievously. "With the way I'm moving they would know instantly we're doing."

"What?!" Dib said, jerked out of his blissful daze. "Zim, get down!"

Zim started bouncing even faster. "It's kind of hot." He said, teasing. "Hey!" He yelled then instantly ducked when a few students looked up, giggling.

Dib grabbed Zim's neck then and held him down, thrusting hard and fast up into him. "You so bad." He whispered gruffly into Zim's ear - or into the side of his head where an ear would be if he had one. Dib didn't notice this, however, since Zim's black hair was long enough to cover it. "I'll have to look out for you."

"Ah." Zim gasped, unable to reply now that Dib was fucking him so hard. His body rocked back and forth with the force of Dib's hips. "I'm going to cum!" He said then clenched his teeth together and did just that, all over Dib's stomach and chest.

"Me too!" Dib said, a little too loud. Zim remembered how loud he had grunted the last time and he put both hands over Dib's mouth. Dib thrust a few more times then cried out, but his voice was muffled by Zim's hands. He emptied himself into Zim then relaxed, panting. He looked up into Zim's eyes and couldn't help but laugh, pulling Zim's hands away from his face.

Zim started to sit up and turn to look out the window again but Dib grabbed him by the hair and pulled him back down. He kissed Zim fiercely. "Stay here."

"Okay." Zim answered with a happy smile, getting comfortable and snuggling with his new lover on the hard, cramped desk. "I get it!" Zim said after a few minutes. "It's 'what's a HEN WEIGH'? About 2 pounds! That's so dumb!" Zim laughed.

"Yeah, it is." Dib said and laughed along with him.
