"In the end, it will be every man for himself."
Loki leaned forward, as his sharp-toothed smile filled Thor's vision. Loki's eyes were black; no hint of their former clear green remained.
"It will be my hands around your neck; my nails in your flesh." Loki's voice was barely a whisper. It seemed to slither across Thor's skin, somewhere between the caress of a lover, and the lick of a whip. Thor wanted to struggle, to push Loki's weight off of his chest, but Loki's voice curled in Thor's head, jumbling his thoughts. Loki stroked the other's throat, fingertips grazing over the quick pulse of Thor's heartbeat.
"My lips will swallow your screams."
Thor closed his eyes, and a pained expression twisted his features. Loki's words always had the ability to cut with little effort. He had watched countless battle-scarred warriors fall beneath a turn of phrase or even an arched eyebrow.
He never dreamed his brother would turn that vicious weapon against him. Blades and spears he could repel. But Loki's words left him defenseless, and stripped to the core.
He desperately wanted to fight, but his arms lay limply at his sides. Mjolnir was within his grasp, but he did not call for it. As Loki pressed his cold lips against Thor's mouth, a tear slid down his cheek. The only thought Thor could hold on to in the middle of his metal turmoil was, Why Loki?
He was unprepared for the long, slim blade that slipped underneath the layers of his breastplate to bury itself deep within his heart. Thor cried out in agony.
Loki twisted the blade back and forth as Thor buckled beneath him. Loki's tongue slid into his open mouth, and just as he promised, he swallowed Thor's screams.
A/N: That phrase from the Avengers trailer has been running circle in my head lately, and then the rest of what Loki said in this little vignette came along soon after. Couldn't help myself. I had to write a little something. (Despite having many other ideas on the go!)
