Summary
“Are you alright?” Optimus asked, instinctively. He scanned his frame again, but there was no major wound, nothing that would bring Megatron to his knees like this. Optimus reached out a hand, automatic. Megatron’s optics widened as he fell to one knee. “What have you done to me?!” he yelled at Optimus uselessly. He curled around his torso, as if to protect his spark. Then, he noticed the hand. “Stay the fuck away –”
Optinus looked at him, confused, afraid, until – of course. The conjunx endura bond. Hurting him, really hurting him, hurt Megatron, too.

Or: Megatron lost his memories. Optimus desperately tries to get them back. -

Summary
His gaze dropped, his expression turning calculating, predatory. "Then you'll make up for it. Now."
The demand was so abrupt, so characteristically Starscream, that Skyfire could only stare for a moment. "Make up for it?"
"Interface with me," Starscream commanded.

King's Crown (Predaking X Ultra Magnus) by Roastedbroc111

Summary
After the war, Predaking stands as the undisputed King of the Predacons though his 'kingdom' consists of only two others. Numbers, however, matter little; each Predacon is a weapon of mass destruction alone, and together they are a force that makes even seasoned warriors wary. To New Cybertron, they are a faction to be respected, if not feared. But Ultra Magnus kneels to no one but Optimus Prime; his leader, his commander, his brother. Protocol demands respect, yet where others tremble before the Predacon king, Ultra Magnus offers only the barest courtesy, stiff and unyielding. Predaking finds it endlessly amusing. He is feared and respected, but a certain commander dares meet him with such defiance. Is it personal? A grudge born from battle, the memory of shattered armor, the prosthetic hand? Predaking cannot decide. All he knows is that the Head of the Elite Guard’s disdain burns sharper than any blade… and it keeps drawing him back.

Is It Stupid To Say "I Love You"? by TheCosmicBean for CarnoBot

Summary
He blushed when he remembered the time he truly smiled at him and laughed, Cirrus felt something for him since then, but he wasn’t sure what to make of it. He was always relaxed around him, more comfortable and his old personality slipped out from time to time, surprising everyone around him. But he didn’t mind, he didn’t mind at all when he was around the tall dark green and black hacker. His garnet optics hidden behind his red visor, his dark and seductive dark face mesh enhancing his plump and soft looking lips making him even more…attractive. And the way he smiled.
Oh, the way he smiles. It just makes Cirrus melt into a puddle of warmth and comfort, just like snow would melt after The Dark Cycle was over and the sun came and caressed all his worries away. He just couldn’t shake his laugh out of his cpu, it was too precious not to hold on to it.
Was it a feeling of trust? A feeling of friendship? Or a feeling…of love?

Summary
War will weight one down, like you are carrying the world on your shoulders. To Ultra Magnus, he is. Rebuilding Cybertron is no easy feat, especially not when there's so many variables, and more just keep arising. It only grows more difficult when he realizes befriending enemies is harder than he thought. He knows Predaking has his sights set on him. Whether it is in hatred, or otherwise, is well unknown. Ultra Magnus extends an olive branch regardless, but will the King accept such a gesture Or will he be the beast Magnus accuses him to be?

Summary
The Decepticons won the war. In the name of peaceful integration, Autobots and Decepticons have been forced together in a "Buddy Program".
In Prowl's opinion that's a needlessly circumspect way of saying the Autobots are now property of the Decepticons, but he's too busy scheming to argue over semantics.

Summary
You're not expecting anything good to come of being called into the office by your boss's boss; y'know, the cold and aloof Cybertronian who runs your entire department? The one people whisper would rather step on you than have to talk to you, he's that cold and disinterested in anything socially fun or even neccessary?
Yeah. That guy.
Contrary to expectations, however, the meeting with Prowl leaves you feeling a lot more optimistic for the future. Sure, he might have the tact of a sledge hammer to glass, but none of that matters overmuch when he's actually being really helpful. Probably the best boss you've ever had, really, when you get right down to it.Pushing you to excel, demanding nothing more than what you can give and expecting no shortage tendered.
...
Now, if only you didn't have to go and fall in love with the bastard, maybe your simple office life could have kept on being simple. Unfortunately for your poor little squishy heart, Prowl doesn't just want you to stay in his department as a productive employee.
He wants you, specifically *you,* to be in charge of ever climbing responsibilities.
Because he thinks you can handle it.
The question is.... Can you? -

Happens during S03 Ep08: Thirst
After the two mechs confess their thoughts of each other, starscream finds himself wondering why the fine doctor felt this way about him. Its not like Starscream has been on good terms with Knockout since he had returned to the Nemesis. But now that they are alone he starts to look deeper into the relationship the two had. Apparently, this feeling is mutual.Or in other words...
This duo finally admits they enjoy each others company and they fuck since that's a much more appealing option then facing the energon sucking zombies beyond the door.

Summary
"Unicron has been defeated and Optimus Prime has made his inevitable recovery. Things are going back to the status quo… until now.
Megatron's frame is changing. Something minuscule creeps through his coding yet his firewalls find nothing wrong.
Unicron may have left behind more than it seems, forcing Megatron to reevaluate the war, perhaps even end it... in a rather unorthodox way"

Summary
"One moment they were leaning across the desk at each other, seconds away from the screaming match of the century, and then Prowl’s optics had flicked down to Jazz’s lips, Jazz had tilted his helm, and suddenly he was tasting his energon from where he’d cut his tongue on Jazz’s fangs. The desk had suddenly been cleared of its contents, datapads and styluses scattered to the floor, and Jazz’s knees were by his helm as Prowl marvelled at how flexible he truly was."
Prowl thinks Jazz is an inconsiderate arse, Jazz thinks Prowl is a complete stick in the mud - but it's hard to be too mad at someone who's going to be in between your legs later.
The next job; don't get in too deep! -

Summary
When Wheeljack’s experimental teleportation portal hurls Optimus and his team through a fractured dimension, they pop out of the other side changed… and not for the better. Now, they must confront the darkest parts of their desires and overcome what they’ve become before it’s too late.
“…Megatron?” He whispered, reaching up to brush his fingers across the elegant white plating framing the other’s face. For a sparkbeat, everything felt still, almost peaceful. But then Megatron’s mouth moved, and reality glitched. Those red optics back in place of blue.
“What the frag are you doing?!” Megatron snarled, gripping Optimus’ wrists tightly in his hands. Droplets of energon dripped down his fingers, matching perfectly with the deep gashes torn into Megatron’s neck.
“I…” Optimus faltered, optics wide with horror. He didn’t remember attacking him—didn’t remember anything after the flash of white plating and those tender touches.

Summary
Skyfire, the beautiful mech, was practically spread eagle on his berth with his digits knuckle deep into his valve. His optics were offlined in pleasure but soon onlined when he noticed something was amiss. You managed to see his face contort in horror before you immediately shut the door. Manually.
You stand there, staring at the ground, trying to not let your fans kick on and trying to process what exactly you just saw before the door opens once more.
OR
You find Skyfire in heat.

Summary
Embittered and defiant, Megatron’s campaign to crush the corrupt Senate isolates him from his friends and his morals, his noble Ascenticon uprising descending into Decepticon violence, control wrested under the erratic leadership of his lover and second-in-command Starscream, apparently insane with grief and endlessly ambitious. The Functionists propose an even greater threat, condemning their ally Sentinel whose elevated social status hangs in the balance with those he loves impeding his success, yet he must succeed, he cannot afford failure, for he would lose everything he has worked for. Inexperienced Autobots unite under the shy and gentle Orion Pax, expecting to be heroes, yet their intervention prolongs the conflict and costs lives, ruining others. After millions of years of war, Megatron’s insane plot is discovered and drives a reconfigured Optimus Prime in a desperate bid to save his people, yet the Thirteenth Prime reincarnate condemns Cybertron to a slow demise. Politics and faith are put to the test as soldiers and civilians love and lose and loathe each other, all-knowing old mechs in positions of power deciding the war-torn future of their surviving heirs in prophecy, the Prime a mere puppet of fate.
