The war was lost. The Autobots had been captured and put in little isolation-cells with their arms above their helms and their ankles tied to the ground, not unlike the human children were before Megatron allowed them to be released. Megatron was not interested in the humans just yet. He was more concerned with the Autobots that had not yet been broken: Ultra Magnus, Wheeljack, Arcee, Bulkhead, and their pesky leader, Optimus Prime.

Megatron was letting different Decepticons take an Autobot as their own to break and tame. Megatron had chosen Optimus, who was his from the beginning. He had always claimed Optimus as his own, in battle and in scenarios. No one faced Optimus. No one. Only he could have that privelage.

He wandered down to cell A-87, where Optimus was hanging out. He chuckled at his own joke and he opened the door. The Prime was staring at him, his optics dim. "Hello, Optimus..."

The Prime bared his denta in a warning, but the warlord only chuckled and patted his cheekplate. Optimus snapped at his servo. "Servos off..."

Megatron went around behind him, pressed a hot panel to his aft. Optimus gasped and hissed, but the submissive part of him whined for more from the warlord. "Oh, soon you will be hungry for my touch. You will see."

He kissed at Optimus' neck, nibbling his audio. The Prime's breath caught in his vents and he squirmed, but his body betrayed him by rubbing back against the warlord. "Megatron, please..."

"I would be willing and honored to invade your little valve, but you are not tame yet. You will beg for me, and I will take your valve and stretch it around whatever I please. Is that comprehendable?"

Optimus snarled, but his helm moved to nod. It was better to not argue with the mech, especially when said mech was Megatron. The warlord smirked and patted his helm as if he was a happy sparkling. Then the mech reached into a little pouch that he had in his servo and produced a jelly cube. "Are you hungry?"

The Prime's optics widened. He had not fueled in weeks, so of course he was hungry. He moved forward a bit, trying to get closer to the jelly cube, but Megatron pushed Optimus back. "Open."

Optimus jerked his helm back at the command, but Megatron made the move to put the cube back. The Prime whimpered and slowly relaxed his jaw a fraction, then a little more. Soon, his mouth was open and his glossa was pressing against his lower lip. Megatron touched the Prime's lower lip and the Prime's glossa slipped free. The warlord put the jelly cube in his mouth, stroked the glossa when he pulled his claws free, then smirked at Optimus. The Prime was shivering and chewing on the cube. He was starving, Megatron realised and he gave the Prime a second cube. This time, he didn't make Optimus beg for it. He let the mech take the second jelly cube and devour it. Then he patted the Prime's helm and grabbed his chin.

"You'll be all mine soon, whether you like it or not." He tied a soft leather collar around the Prime's neck and Optimus' optics dimmed and dropped to the floor, studying Megatron's pedes. "You like being mine, don't you?"

The Prime whined gently and forced his helm to move up and down. He was rewarded with another jelly cube. Optimus' processor and body were learning, but Optimus was still fighting against them.

ooo

Megatron sat on his throne, Optimus at his pedes. The Prime was supposed to be paying attention to Megatron and Megatron alone, but the Vehicon behind him who was giving a report was distracting him. Optimus was more interested in what the Vehicon had to say than what cues the warlord was giving him. Megatron dismissed the Vehicon, grabbed Optimus by the collar and forced the Prime's face between his legs. "Optimus," the warlord sighed.

The Prime mewed in response, having learned that pets don't talk. He bit his glossa to keep from doing just that.

"Do you recall what cues I was giving you?"

What was Optimus supposed to do? Speak and then get punished? Though Optimus recognized the cues, he shook his helm. He expected pain, but Megatron simply stroked the Prime's helm. Optimus relaxed, and then Megatron grabbed his audio finial and tugged. The Prime yelped.

"That's too bad..." Megatron's panel slid back with a soft hiss and Optimus' optics widened. The warlord didn't really want him to do...that, did he? Megatron pushed his thumb into Optimus' mouth and guided the head of his spike towards his lips. Optimus whimpered. He did, Optimus thought. "Because now you have to make up for it, don't you?"

Optimus mewed softly, gently taking the spike into his mouth. He held onto Megatron's thighs as he worked, his optics dimming in shame. He was a Prime, reduced to sucking another mech's spike! If the others could see him now, they would laugh. They would torture him, make him do stupid things just for their amusement...

Megatron patted Optimus' helm and pulled the audio finial again. Optimus released his spike, whining. Fluid was in his mouth, on his glossa, dripping down his chin. He had been too distracted to realise Megatron had overloaded.

"That's a good pet."

Optimus whimpered as Megatron lifted him and laid the mech in his lap. The warlord watched the Prime, then put a ball in his servos to keep him busy while Megatron worked.

The Prime stretched out, laying across Megatron's lap on his belly and he sighed, squeezing the ball. He started to throw it and catch it, but then he miscalculated and the ball went flying across the room. Optimus slipped down onto the ground and crawled to get it, but it continued to roll.

Megatron held a small remote in his servo and he watched his pet chase the ball. "Stay on your servos and knee struts or you'll get a nasty surprise..." He smirked when the Prime obeyed. He watched Optimus chase the RC ball until the Prime stretched out on his belly and yawned.

Was he truly broken now? He walked to the Prime. He made a signal with his servos. Optimus jumped up and got on Megatron's left side.

The warlord smirked and stroked his pet's helm.

He had won.

ooo

Optimus was eager to please his master, Megatron found. It had taken months of training, but Megatron finally got what the wanted: a loyal pet. He had the Prime on his berth for hours now, the little mech squirming and begging for his master. Megatron felt bad for breaking him down like this, but...he didn't feel bad for long.

He mounted his pet and taught him who belonged to who.
