"What took you so damn long?" Dib snapped when the door finally opened. Zim, seeming panicked, frowned hard at the floor with wide eyes.
"I.. I wasn't expecting you today.."
"You should expect me every day!" Dib replied, pushing his way into the house and tossing a few bills on the table. Zim shut the door and walked over to them, but Dib put up a hand.
"Stop counting it," he said. "You do better when you don't know how much you're working for."
Zim swallowed and nodded, stepping over to the lift. He called it up, and they rode down in silence, having to stand uncomfortably close to each other to both fit in the small lift.
They reached the room and Zim began undoing Dib's jeans, telling his mood already from the way he spoke. He pulled them off and Dib undid his own shirt, then he took the alien by the arms and threw him onto the bed. Zim grunted softly in pain, weakened by the four days lack of food. He wondered why Dib had waited those four days; the breaking of schedule unnerved him, and he hoped it wouldn't be like this from now on.
Dib proceeded to tear Zim's clothing from him, rougher than usual. His hand grazed a tender spot on Zim's shoulder, where he had injured himself lifting something heavy in the lab, and the Irken winced, raising a hand to move Dib's. The man growled and took his hand, pressing it to the bed above his head and snarling curses at him even as the alien cringed beneath him.
He snapped something close to Zim's face that he didn't even hear. The alien antennae were pressed flat against his head in fear and submission. The Dib had never been like this before. Smug and arrogant and abusive, but never angry.
Dib proceeded to punish Zim for his wrongful actions, beating him off the bed and into the floor with a flurry of insults and curses as he crushed the alien. He then rose and dressed himself, not looking at the shivering, bloodied being curled partially under the bed.
The human left, and Zim wept as he never before had.
When he finally stopped, he struggled to his feet shakily and stumbled upstairs. It sounded like rain outside, so he may as well use it.
When the lift stopped and Zim swayed into the living room, his swollen eyes lighted on the money. Had Dib forgotten it? Must have, there's no way he paid just to beat Zim.
Zim waited two days for Dib to return for it, but the need for food and supplies became too great and Zim spent the money. It was never mentioned by either person.
