"Dib-Stink!" Zim growled, claws digging into the humans pale flesh. Dib moaned at the sound of his name coming from the alien's soft green lips. He caught a wiry, sweet antenna in his mouth, sucking frantically on the tip. Zim gasped, wrapping his short legs around Dib's waist. Who would've guessed that after years of fighting it would lead to this? Lying on the cold, concrete ground of Zim's lab; bloody and bruised from their most recent fight, making out. Neither would've. They would've killed you for even thinking it. Fried your brains for talking about it. Then laughed about it. But, here they were.
Wanting, needing each other with a fiery heat. It burned, consumed them just like their hatred. This by the way was quickly dissolving. As if it had never been, with each cry or gasp. Every time they moaned each other's name.
Dib felt the wall crumbling. The steel wall that hid everything, he felt from the alien and himself. Then with one word, "Dib!" it fell completely. There was no insult tacked on at the end and that…that broke him into pieces. His heart filled with suppressed joy and…love.
All with the simple, saying of his real name in the heat of passion.
"Zim," Dib whispered, around the antenna in his mouth, staring down at the beautiful alien flushed with lust. "I love you."
