Author's note. There's a brilliant new group on deviantart called 'Dominated Megatron' by Omega-Knight01 and I've written this story for it. Check it out and if anyone has any similar stories, I hope you'll post them there.

Enjoy and please review.

Optimus Prime looked down with much satisfaction at the Mech currently bound to a berth. They were in a rather empty room in the newest section of the Autobot base where a specially prepared set of quarters had been prepared for this wing of the Ark. All the rooms were very Spartan but they did all contain basic washrooms which added the only real luxury to these quarters. They all contained a simple but decent berth which was easily big enough for large heavily armoured Mechs although a few of the berths had extra support for Seekers.

The only other real items in the room were some shelves where data pads or other trinkets could be kept. The rooms weren't very unusual, most bots started with extremely basic quarters which they customised according to their tastes. The things that set this residential wing apart from normal ones were the shackles on the berths and the fact the doors could only be locked from the outside.

"I hope you are comfortable," Optimus now said to the Mech who glared up at him. "Those were tested out several times to ensure they didn't strain cables. As long as you don't thrash around too much that is."

The Mech didn't answer, just continued glaring.

"The others are safely in their quarters," Optimus continued, he wanted to assure his prisoner on that point if nothing else. "And my Mechs are...taking care of them."

"Like you're going to take care of me?" sneered his prisoner, finally speaking for the first time since waking up.

"That is correct," Optimus acknowledged as Megatron scoffed. "You're my responsibility now and I take that very seriously."

"I'm sure you do," Megatron said coldly, flexing his arms as he tested the restraints holding his arms above his head. They were position so that if he was relaxed, they didn't strain and hurt his arms but if he tried to get away, they would quickly get tired.

"I'm afraid you can't break free," Optimus pointed out although he wasn't sorry at all.

He was rather enjoying admiring Megatron's form all laid out for him and for once, he was close enough that he could do said admiring with worrying about Megatron's reaction. Of course Megatron was very large and bulky but no more bulky than Optimus himself. His armour was mostly a darkish grey and very scuffed and scratched, making Optimus desire to buff it all out. That could wait until later however.

"This won't be easy for you Megatron," the Autobot leader began as he leaned down to trace his hand across Megatron's chassis.

Megatron growled low in his throat, his whole body tensing as he couldn't physically remove Optimus's arm. This made Optimus chuckle slightly as he moved his hand until it cupped the grey Mech's cheek which trembled against his armour. Optimus now moved his thumb so that it stroked Megatron's cheek causing the Mech to growl.

"Get the frag off me Prime."

"No," Optimus rumbled softly, moving even close to the berth. "I've been denied for a very long time Megatron, I'm not about to be denied now."

"What are you talking about?" Megatron demanded.

"I've wanted you Megatron," Optimus murmured quietly. "Every time we've fought hand to hand, my longing for you has grown. Feeling your taunt body against mine, your strength and cold passion arouse such emotions that I can't describe."

Megatron's response was to bare his fangs and the Prime knew he had to be careful not to move his hand too close to those fangs. Megatron would sink them right into his hand given any single chance. What a pity, as there was something Optimus very much wanted to place in Megatron's mouth but right now, it was impossible to do so without being severely bitten.

"You know what I want Megatron," Optimus said in a low growl of want. "If you give it to me, I can give you pleasure you've never even dreamed about."

"Go to the Pit, Prime," Megatron spat angrily.

Optimus merely sighed.

"I suppose it was too much for you to accept this, at least immediately," he said in a tone that hinted sorrow. "But I'm sure I can change your mind."

And his face mask parted, allowing Megatron to see his full face for the first time and leaned down to kiss his other cheek. After briefly gazing at the bare face, Megatron jerked his head away, growling deeply. Optimus chuckled lightly while wishing he could taste who lips but he knew Ratchet would not appreciate it if he came to the Med Bay with half his mouth gone.

However, he did allow his glossia to swipe that rough cheek, tasting ozone and bitter metal. Megatron growled and thrashed again, hating the feel of Prime on him. But that was only the beginning.

"Mmm, you taste better that I imagined," Optimus purred.

"Frag off," was the reply.

"Don't be like that," Optimus chided softly. "I'm only speaking the truth."

Growl. Optimus sighed and moved away from Megatron's face. There were other ways of wringing pleasure from Megatron's lips. So he moved to the other end of the berth were Megatron's feet where bound and moved between the large, grey legs. Of course, Megatron struggled and tried to crush him with his legs but Optimus easily pushed them apart and kept them there.

"You've always wanted to see under my face mask," Optimus murmured as he lightly touched the place between Megatron's legs. "But there's something of yours I've wanted to see underneath."

"Who would have thought the Prime was a pervert," sneered Megatron, probably hoping to upset Optimus but it didn't.

"If loving your body is pervasive then I guess I am a pervert," Optimus chuckled as he bent down to kiss Megatron's cod piece.

"Don't you dare!" snarled Megatron as he thrashed around but to no avail.

"Oh yes," Optimus groaned, this area was always a touch warmer than the rest of the body and that was in a non aroused state.

Using his shoulder to brace one of the straining legs, Optimus now caressed the quivering cod piece, tracing a slight scuff he found there. Oh yes, he would enjoy buffing out this body later on. Leaning even closer, he licked the cod piece which tasted similar to Megatron's cheek but he thought he could detect a hint of lubricant. Well, Megatron was a Mech and Mechs had needs...

"You taste even more delicious," he moaned, still licking. "I can't wait to see what you taste like inside."

"I swear I will kill you Prime," Megatron half snarled, half shouted.

"A risk I'm willing to take," Optimus laughed as he started to find a way to release Megatron's cod piece.

"Let me in, Megatron," Optimus murmured as Megatron bucked his body, snarling like a wild animal.

"Slag you!" Megatron yelled as Optimus finally managed to hook his fingers in the catch and pulled the cod piece.

"Mmm," Optimus hummed with appreciation as the grey Mech's equipment was revealed to him.

Of course at the moment it was soft and limp but Optimus hoped to soon change it. The Spike looked long and thick and while most of it was smooth, there were two ribbed strips on either side of it. Spikes varied between Mechs but ribbed parts always caused maximum stimulation within their partners as well as being very sensitive. Optimus very gently took the Spike in his hand, feeling it carefully and wanting to commit every detail to memory.

Megatron let out another growl but Optimus was sure the Spike had stiffened a little. Naturally anyone handling another Mechs's Spike meant there was bound to be a small amount of arousal. Optimus squeezed slightly and there was some definite stiffening now making the Prime grin broadly.

"This won't be so difficult after all," he commented in amusement as Megatron offered him another growl.

He lowered his mouth to the Spike in his hand and licked the very top of it. It tasted so good, a little salty but also very sweet. There was no lubricant at the moment but he'd soon change that as he slid his mouth over the very top of Megatron's Spike and gently sucked. Megatron groaned and shuddered, snarling as his body started reacting and his interface systems fired up.

"Leak for me," Optimus commanded as he briefly released the Spike to speak. "Let me taste your delicious fluid."

"No," Megatron hissed.

"You say no but your body says yes," Optimus stated smugly as a drop of transfluid appeared on the tip of Megatron's Spike.

Happily, he lapped up that drop and was pleased when another followed. Optimus was enjoying this immensely but it wasn't enough, he wanted much more. Megatron wasn't nearly aroused for his tastes; he wanted more, so much more. So he started to squeeze, rub and suck, slowly at first and then increasing the pressure steadily. For his efforts, the volume of transfluid increased so that he was happily swallowing away.

He heard growls, snarls and curses from his restrained prisoner but he ignored them, the Spike was swelling with fluid until it became fully engorged. Optimus leaned back to admire the erected Spike, standing tall and proud. Fluid now leaked copiously from it, reaching up towards Optimus's admiring gaze. He gently stroked the long length, he could easily worship this Spike and this alone.

"You're magnificent Megatron," he complimented and caught Megatron rolling his optics in disgust.

"But now I want more," he purred and clambered on top of the grey Mech who suddenly looked worried.

"Your Spike was wonderful," he continued in a slightly evil tone. "But I bet your Port is even better."

And with that, he thrust into the struggling Mech's Port and cried out in ecstasy even as Megatron cried out. Their voice combined in unison until...

Optimus woke with a gasp, his systems overworking and his cod piece gaping open with his Spike extended. As he lay there, trying to get his systems under control but he couldn't control the raging hard on that burned and throbbed. With a growl of frustration, he grabbed hold of his Spike and began to pump; he wouldn't get any peace until he found release. It had been the same for several recharges, he had tantalising dreams about the object of his desire but they always ended before he got any satisfaction.

With another growl, he swore that he would solve this problem, even if he had to kidnap Megatron to do it.

Author's note. This is just a teaser for what comes next; I promise you will enjoy it. Until next time.
