He'd never bent like this, surrendered so much, for anyone save his commander; but Rodimus Prime was made to be Galvatron's equal and anyway Cyclonus didn't think his lord would mind.
Admittedly, Starscream wouldn't be so easy to explain, but if pressed Cyclonus would place all the blame on the Prime. The Seeker was as whole as he'd been at the moment of his coronation, lips curled in a mocking smile, his new body humming with the Unicronian taint as he secured the shackles around Cyclonus's wrists. "It's done," he pronounced, and drew his fingers deliberately down Cyclonus's chest with an electric buzz that felt like thorns. Cyclonus shifted in his bonds as he reflected that when Unicron designed him, he must have derived his talent for interrogation from Megatron's memories of this creature.
"Good," came the quiet reply, and Rodimus Prime rose, walking with measured steps across the room to them. Cyclonus's gaze never left him as he knelt, soothed the sensors agitated by Starscream's touch with his own, cupped his cheek in one hand. Rodimus had always been maddeningly gentle, almost afraid of his own strength, but being subjected to it while helpless was enough to make Cyclonus want to scream at him. It helped that he didn't think the Prime was doing it deliberately; he contented himself with an engine-rumble and a turn of his head to nip at Rodimus's fingers. "Hey," the Prime laughed softly, and pulled away, but just barely. Cyclonus growled and leaned in after him before a thorn-wreathed fist in his wing brought him up short.
"Mind your manners, prisoner," Starscream sneered, grinding his energy signature into Cyclonus's wing. Cyclonus snarled and jerked against his bonds.
"Rodimus-!" he cried, and was dismayed to hear elements of a rough plea in his own voice.
"It's fine, I've got him," Rodimus murmured, reaching over to curl a hand around Starscream's nape; and all right, it may have been a display put on for his benefit but Cyclonus wouldn't deny his... interest at seeing how Starscream bent his head under the Prime's hand, dimmed his optics in submission. He didn't believe for a moment that his predecessor was truly under Rodimus's control, of course - but if Starscream was willing to play along, then so was he. The fist in his wing didn't ease, but against the gentleness Rodimus promised the pain was almost a welcome relief.
"Better," Cyclonus grumbled, ceasing his strife and laying back. Rodimus's optics lit in a smile, throwing cool light over both his fliers.
"Good," he replied softly, and offered his fingers again; Cyclonus took them in his mouth, but didn't bite, even when Starscream increased the pressure on his wing. Rodimus still had his other hand on Starscream's neck, guiding him as the Seeker stroked pain right up into his wing joint.
Cyclonus groaned around Rodimus's fingers, arms twisting in their bonds. The Seeker smirked, the expression half-hidden from the Prime, and angled his fingers to force them deeper. Cyclonus shuddered and tried to groan again, but Rodimus bent swiftly to muffle the sound with a kiss.
Cyclonus arched under that kiss, probing Rodimus's mouth with his glossa even as the intoxicating sweetness threatened to overwhelm him - bound he may be, but he wouldn't be broken, not from just a kiss! "Rodimus," he growled as the Prime pulled away. "Afraid to test your power against mine?"
It was a petty taunt and they both knew it; Rodimus grinned broadly at him, and Cyclonus had to fight to hide a smile of his own. "I don't have to," the Prime said slowly, and flicked his gaze to Starscream.
The Seeker grinned viciously. "Yes," he hissed, and descended upon Cyclonus, savaging his throat with mandenta and glossa. Cyclonus gasped, more in surprise than pain, but only flinched when Starscream reached up toward a sensor horn.
Rodimus caught Starscream's hand in midmotion. "No," he said firmly, and though Starscream snarled, pride ruffled at being thwarted, he subsided to the Prime's will. He took his revenge, of course, in the form of a bite to Cyclonus's throat that nearly tore the metal, but aside from a shudder Cyclonus didn't deign to pay him any heed. He preferred to watch the Prime, fascinated to witness a side of him he'd never even shown Galvatron.
"I think I may have underestimated you," Cyclonus murmured.
That earned him another grin, Rodimus's optics brightening as if Cyclonus had just given the highest of praises. "That's okay, I forgive you," he murmured, and bent to kiss him again, gently pushing Starscream harder against Cyclonus's throat as he moved.
This time Cyclonus allowed himself surrender, just as Rodimus was allowing himself control; Rodimus's glossa slipped into his mouth and he sighed as he twined it with his own.
