It wasn't exactly by choice but some sort of ceasefire needed to be discussed, the Decepticons were restless and needed more rations.
No Decepticon was too pleased about striking a deal with their enemies but it felt like the wisest course of action after some deliberation.
It took even longer to convince Galvatron it was even a half-decent idea.
Cyclonus had prevailed and managed to bring him along after all there was no way he could talk in his Master's place, the decision needed to be agreed between both leaders.
But here they were instead, down the gold plated Autobot corridors hidden in a cubicle designed for waste disposal, limbs entangled.
Cyclonus breathed heavily over Galvatrons abdominal plates his hands clasping his lords full aft keeping his pedes off the floor and his back pressed into the wall as he thrust himself further into his lords warm folds. Each thrust scraped Galvatrons back up and down the wall no doubt staining said wall with deep purple scratches and flecks of gold peeling off and clinging to the Decepticon leaders back glued to him by the thin film of coolant now covering him.
Cyclonus squeezed the aft cupped in his hand and ran his tight grip over his thigh, a fanged dental unit poked out of his mouth as a grin spread across it when Galvatrons reaction said it all and those thick legs wrapped around Cyclonus's waist tightly pulling Cyclonus deeper in with a pleasured moan.
Galvatron grabbed a hold of Cyclonus's wing struts and pulled him in closer to his own body forcing Cyclonus to twist his head upwards nuzzled into Galvatron's neck. Here Cyclonus could feel just how desperately his master fought for cool air and just how coolant ran down him in a vain attempt to keep him cool. Cyclonus lapped at the rivulets of coolant, Galvatron moaning with each lick, he gasped and growled pleasurably, engine rumbling joyfully, every time Cyclonus stopped licking to nip and suck upon the exposed wiring of his neck.
The rush was quite empowering and Cyclonus thrust harder and harder eliciting whimpers and short sharp gasps. Galvatron was inacpable of forming proper words as Cyclonus ran his hands up his back, now that Galvatron kept himself supported, rubbing at all the joints and lines in his armour as he kissed and nipped harder at his neck.
Galvatrons moans increased in intensity as Cyclonus desperately tried to hold onto the rising heat in his abdomen, waiting for his lover to climax first.
That was a voice.
And it was not Galvatrons.
A cold shiver of panic ran up Cyclonus's back conflicting with the far-too-pleasurable heat spreading round his body making him jerk and tense up into Galvatron. He reached up and clasped a hand over Galvatrons mouth stifling his ever increasing moans.
"M-my lord" he gasped worried that the nearby Autobot would find them and what the resulting mess would do to their chances at the talk later.
Galvatron mouthed against his hand and Cyclonus snapped it away obediently.
"N-nnn...no" he rasped with a wicked grin and a tighter grip pushing himself as far as possible onto Cyclonus, enveloping his very being within himself.
"Let them hear."
