“Megatron?”Optimus raised his head from the neck cables he was nibbling and stopped hisfingers’ movements. “You’re so tense. We don’t have to do it if you don’t wantto.”

“No, I… I’mfine.” Megatron closed his optics and forced himself to relax. “It’s just… Ithas been a long time.”

Optimushummed in understanding and proceeded to lave Megatron’s neck with attention.He knew that trust was a rare and dangerous thing among the Decepticons, especiallyhigh-ranking Decepticons. Especiallytheir leader. Optimus had a lot of critique to offer, but this was not the righttime. Perhaps a demonstration would be more effective.

He wentback to gently rubbing Megatron’s closed interface panel, feeling it growwarmer under his ministrations. When his fingers slipped to tease the sensitivethigh joints, he could feel stray drops of lubricant forming at the seams andthe faint trembling of those silvery thighs. Megatron groaned, trying to pushinto Optimus’s touch, and the Prime smiled.

“Patience,”he chastised, pushing Megatron’s hips down with the flat of his palm. “I toldyou, this will be no quick romp in a dark passage. We’re going to do it my way,and this means that you’ve got to do what?” He bit Megatron’s neck slightly toaccentuate the question.

“Ah!”Megatron’s thighs twitched again. “Optimus, I know…”

“Answer thequestion, Megatron.” Optimus rolled the thick cable between his dental plates.They were in no way sharp, but still made his point clear. “You’ve got to..?”

“…To obeyyour commands.”

“That’sright.” Optimus licked the abused cable. “And since you’re being so good… Open.”

Megatronsighed in relief as his interface panel retracted, and Optimus couldn’t help butsmirk. His slow approach was already bearing fruit, judging by the sheer amountof lubricant that flowed onto his fingers. Still, it didn’t mean that he wasgoing to speed up. He traced the rim of Megatron’s valve with one fingertip,enjoying the wet heat of it, smearing the lubricant all over the swollen folds.What a sad life Megatron had sentenced himself to, if nobody had ever beenallowed to show this valve the appreciation it deserved. Optimus found thepulsing nub of the anterior node and circled it, never quite touching itdirectly.

“Prime!”Megatron’s back arched, and his claws dug into the berth’s padding so hard theycould tear it. “Stop teasing, slag it!”

Optimusjust laughed, allowing his other fingers to slide against the valve’s opening,never entering it.

“I willstop when I deem it enough,” he said, smirking. “And I want to see how manyoverloads I can wring out of you before I properly take you.”

It was two,as he soon learned: Megatron overloaded to the sound of his voice the momentOptimus finally rubbed his anterior node, and second time – on Optimus’sfingers, biting the back of his own palm to muffle his cries and riding Optimus’shand with ragged, fervent thrusts.

This waswhen Optimus finally took pity on him (and on his own straining spike). Hookinghis arms under Megatron’s thighs, he moved between them and nudged his spike’stip against the valve’s opening. Megatron whimpered – truly whimpered! – and Optimus paused.

“Do youwant it?”

It tookMegatron several seconds to comprehend the question, and he groaned, his headlolling to the side.

“Pits,Optimus… Yes! Yes, I want it! Come on, frag me already!”

“Very well.”Optimus braced himself and finally pushed inside.

Thesensation overwhelmed him. He could tease Megatron all he wanted, drawing outevery caress and making him fall apart under his touch, but Optimus couldn’tdeny how it all affected him, too. Soft, silken walls of Megatron’s valveclenching around him, slick and scorching hot after two overloads, charge crackledwhere their EM fields clashed… Yet Optimus refused to give Megatron that fastand rough frag he was probably expecting. Collecting himself, Optimus opened hisoptics he didn’t realize he shut and began moving – slowly, deliberately.

Megatroncried out, thrashing underneath him, but, to Optimus’s surprise, he didn’t snapat him or demand that Optimus moved faster. The tension that held his joints inan iron grip went away, leaving him warm and strutless; Optimus leaned down tokiss him, Megatron’s thighs still in his hold, and Megatron wrapped his armsaround Optimus’s neck to pull him close.

“Yes…” Hegasped between the sloppy, languid kisses. “Frag me! Optimus…”
