Megatron was feeling sick once again. He wasn't tied up. Optimus, before he went into labor, he untied him so that Megatron could give birth to his sparkling as comfortably as possible. There was a pool set up for him with water that bubbled whenever he pressed the red button. He was laying in it now, stroking his belly and wincing whenever the contractions returned. He could see spectators watching from their window and he wanted to rip their throats out, but he was in labor.
He stretched out, crying out. The clear water was turning blue with Energon. He whimpered, having not delivered a sparkling before. He reached between his legs, feeling for his valve. He found it, stretched around a smooth helm. He cried out in fear. How could this sparkling get out? It was so big and his valve was so small.
Optimus decided to come and visit him, sitting at the edge of the pool and stroking his helm in a way that soothed Megatron slightly. He stopped squirming and crying, but the tears kept rolling down his cheeks.
"It hurts," he whimpered.
"Does it?" Optimus stopped touching him immediately and he looked between the warlord's legs. "It is coming out slowly. I hope you are not bored as I am. I will return later. This sparkling is so large it may take a while for your body to push it all the way out."
"What?" Megatron gripped the edge of the pool so hard he thought he heard it crack.
"Oh, I have no doubt it will take a long time. I have my sparkling and Energon waiting for me. I cannot leave my newborn for long. It cries for me."
Megatron whined for Optimus, pleading for him to stay. But the Prime left him with the pain.
He looked between his legs and he saw a helm poking out of his stretched valve. He started to wail, arching and squirming. The helm was blue, just like Optimus', with a face to match. He cried out when the helm was all the way free. He was worried the sparkling would try to breathe, so he tried to get out of the pool, but he kept slipping back in.
The movement allowed the shoulders to approach. That made Megatron freeze, feeling his valve stretch wider than it ever had before. He started to whimper, not knowing how to react. He squirmed with more vigor, trying to get out of the pool. He kept an optic on the sparkling, but it was still with no change in behavior.
Finally, he was out, but the pain was nearly unbearable. He wanted to cry aloud. Tears were already working down his cheeks, burning his optics and making him feel ashamed.
The shoulders were finally free. They were massive shoulders, just like both creators'. He sighed as the arms slipped free, then the hips.
The sparkling started to move, just slightly. It lifted its servos, curled them into fists, scrunched up its faceplates. Megatron tried to stand, wanting to find a towel or a blanket. The sparkling drug on the floor while Megatron scrabbled for the towel he spotted. The legs were pulled free because of the mech's mad scrabblings, and then the pedes were the last things out.
A cord still connected carrier to creation. Megatron waited for someone to sever it, waited for someone to come and help him, but no one did.
He was left alone with the sobbing sparkling that never settled no matter what Megatron tried to do.
He was laying on his side when Optimus came, touching the warlord's helm and smiling down at the creation that babbled and cooed up at its sire.
"It's femme," Megatron sighed.
"I know. She is beautiful. Your creation is a mechling." Optimus laid a blanket on them. "I hope they learn to get along," he whispered.
There was something pushed into Megatron's valve and he cried in pain. A sparkling had just come out of that! He was sore for Primus' sakes! But Orion had been sore and he kept abusing him...
"Hurts? I apologize." Optimus kissed his helm. "I remember how much it hurt me, especially when it vibrated."
It was set to the highest setting then, and Megatron cried out. The femme started to whine for food, licking her carrier's chest plates.
"Feed her, Megatron." Optimus set a bottle in the warlord's servos. "I will return, maybe, in the morning. See you then, my dearest Megatron."
Megatron didn't know what he did to deserve this other than what he realized...had he done something else? Something more serious? He fed his whining creation, then got up and walked towards the berth where he laid down, curled into a ball. The vibrator died sometime during the night, but he was still in pain.
