Starscream strode down a hallway, having returned from a late night flight. He often loved to go and fly under the stars to clear his head.
Distracted as he was, Soundwave didn't hear or detect the seeker until they both rounded a blind corner and the second in command bumped into him.
"Watch where you're going!" Starscream growled, and barged past the mute, wrongly identifying him as a Vehicon.
Soundwave stumbled from the force, and grabbed the seeker's shoulder to halt his progress. He could hear his comrade's spark pulse faster from the fright, and found it intoxicating, even as the mech whirled around and stared at him in shock. To the mech's credit he recovered quickly.
"What are you doing up so late?" A hint of nervousness was in his voice, a typical tone whenever the pair were alone. Starscream never trusted Soundwave. The eerie silence, the blank, expressiveness mask, the way the blue mech waited with unrelenting patience...
"Patrolling." The Vehicon's voice he used as he lied came out as smooth as silk as he regarded the seeker. He watched the mech flinch with rapt fascination as he took a step forward, eating up the distance between them until they were inches apart.
He wanted to get even closer for some reason, and the only way to do that was to distract him. He used his stoic silence and unreadable screen as tools to achieve this. All the while his hands eased closer to the mech's sides, ready to grab when needed.
Starscream backed away, his nervousness growing by the moment.
"W-what are you doing!?" He glared. "If you must know I went for a flight; I swear I didn't do anything wrong!" As he backed up his back and wings were pressed against the wall. He was trapped.
The silent mech kept coming closer. He wrapped one of his hands around the top of the seeker's neck to restrain him, earning a small yelp from the cornered mech in the process, while his other hand pressed against the slender mech's chest, pushing him against the wall. "S-soundwave! Let me go at once!" He got nothing in response aside from a head tilt, as though the third in command was listening intently to something else. "As your superior officer I demand you to let me go this instance!"
Instead what he got was the blue mech leaning in closer, and a strange purr, long and continual, came from Soundwave's engines, while Starscream's head was shifted to the side, his neck exposed to the other flier.
His protests and struggles were momentarily distracted when he heard a small hiss, and caught the sight of the mech's mask slide, just a little, revealing a light face, and with it, a horrifying discovery. In the corner of his optic he saw the split, vampiric mouth that matched those of a Terrorcon.
"Stay back!" He yelled in a fruitless warning as he struggled with all his might.
Desperation made Starscream strong, but the unrelenting, building hunger made Soundwave ignore the kicks to his legs and the thrashing that threatened to unbalance him. His grip remained firm, pinning the struggling seeker in place.
His mouth split further, widening his gape, and feeding cables shot forward as he lunged, craving the fuel that he could feel pulsing just beneath the exposed neck. Just as he was about to bite he felt a pair of strong, heavy hands grab the top of his back armour, and rip him off the seeker and throw him into a nearby wall.
