The bed was comfortable enough, with big soft pillows and a mattress made from the finest Vortian materials. Sheets created especially for sleep, and large blankets that could shelter a whole circus with its size from a powerful rain storm.
But, above all that, laying on the bed, the two boys were tense. Or at least the green one, Zim, was. His lover, Dib, pretended not to notice the anger directed at him and raised a single finger upwards, slowly to poke at Zim's lips.
Zim smacked the hand away before it could make contact.
Dib was not deterred, raised the hand again after a few seconds of debate, tongue sticking out as it made its journey…getting a few inches from the green lips before it was hit down again, flopping onto a nearby pillow.
Zim huffed and turned away more. Dib finger-walked along the bed spread took the digit and got a few millimeters this time before that hand was rejected as well.
Some would've given up, but the paranormal investigator knew his alien inside and out better than anyone, including himself, so therefore kept pushing it.
A black finger nail, painted that way a few nights before, cautiously poked at the lips, while Zim glared, not amused but allowing the contact for a few seconds. Then the jerk swatted the poor boys hand away.
However Dib smiled a little and tried again. This time the finger ran along the seam of the mouth, caressing and delicately touching. He slid the finger inside the irken's lips, and Zim's tongue ran along the finger pad, shivering at the slightly salty taste.
The irken realized what he was doing. He was mad, damn it, and threw the hand aside. It flew too far this time and banged against the head board, making a dull, cracking noise.
For a few seconds, no movement was made. And then Zim sighed and grabbed the injured hand, lifting it to his lips and kissing the red knuckle, before climbing unceremoniously into Dib's arms.
The filthy human smiled triumphtly, tightening the embrace.
