PRESENTING:

ZAGir-The One-Night Stand

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

'This is probably the dumbest thing I've ever done.'

That was all Zim could think about as he pressed his cheek against the pillow, hands gripping the sheets. He felt exposed, with his ass up in the air like that. But more than that, he was humiliated. Humiliated that he would allow something like this to happen.
In fact, he hoped this was worth it, because that was the only time he was going to let it happen, or so he firmly decided as he felt something cold and hard looming at his rear. He shivered.
Gir laughed at him, a greedy, diabolical laugh.

He felt one of the metal tentacles wrap itself around his waist, to hold him in place, he assumed. The others curled and looped in the air, wisping about like live snakes. They made Gir look much more domineering. His eyes glowed a bright red in the darkness, his smile seemed to say "no mercy."
To anyone else, that would have been like some kind of wild, exotic fantasy.
But to Zim, it was a nightmare. A terrifying nightmare.

He dug his claws into the sheets, arching his back and gritting his teeth as he felt Gir press inside. It didn't matter that he'd only started, it hurt. And he wanted it to stop. Gir sensed him tense up, and grinned.
"Who's your master now?"
Zim bit back a sharp remark. "Just shut up and get it over with." he hissed through his teeth. "Before I change my mind."
Gir saluted, and you could hear the smile in his voice as he replied, "Yes, SIR!"
He forced it the rest of the way inside.
Zim pressed his entire body flat against the matress and screamed. "THIS WASN'T SUPPOSED TO HURT!"

They stayed still, for the pain to numb a little.

After a few minutes, when Zim finally caught his breath, he felt it move slightly. But that slight movement was all it took for Zim to realize how good it felt. He whimpered, pressing up against it, trying desperately to find that sensation again.
He heard Gir's breath get heavier. "Master..." he whispered.
But Zim was far from caring what he wanted.
It moved again, stroking that same spot inside of him that made him go crazy!
He forced himself back on it, not willing to let the feeling go.
He found himself pleading. "More, Gir! MORE!"
Gir complied, panting heavily, jamming it up as hard as he could. Pleasure spiked between them with each thrust he gave. Zim was loving all of it, rocking back on the metal appendage with all his strength.
And neither could stop, not with a feeling so new and hot and fanastic.

-A couple hours later-

Zim's knees and elbows finally gave out beneath him, and he collapsed onto the bed, exhausted (and covered in scratches and briuses, if that paints a picture.) Gir landed beside him, breathing fast. Zim immediately pulled him close, his cold, metal body feeling sensational against his skin. He secured his arms around the little robot and buried his face in Gir's neck.
"My god, Gir! That was..."
"Amazing?"
Zim chuckled and breathed in deeply.
"I didn't think I'd ever get enough."
Gir smiled. "You and me both."
