The next morning, Optimus woke with a bit of a jump and felt two arms wrapped around him. His processor took a bit to come fully online as the sheer pleasure from the night before had nearly crashed his systems. The arms belonged to Scourge, and while Optimus smiled as he thought of the pleasure form the night before, he was still a bit apprehensive about this whole thing. Optimus realized that Scourge had fragged him, for lack of better terms, and while it was pleasurable and such, it could lead to trouble as well. But seeing little other option, Optimus bumped into Scourge and woke the bot up. Scourge smirked and planted a heated kiss on Optimus. "Optimus, you taste delicious" Scourge mentioned after the kiss.
Optimus had the decency to blush. "What happened, Scourge?" Optimus asked, demanding to know.
"We fragged because I hit my heat cycle" Scourge sheepishly explained.
Optimus sighed. It must have been the hormones, or Optimus would never had said some of the things Scourge told the Prime he had said during the session. But then Optimus thought of his fellow Autobots. He looked to Scourge. "And what about my friends – the Autobots. I can't stay here while they fight to save this universe."
Scourge soon realized he could take Optimus out of duty but he couldn't take duty out of Optimus. "I will let you go and I will give you this key you seek" Scourge reluctantly replied.
Optimus shot the dragon bot a look, as Optimus knew their had to be a catch. "And just what will it cost me for that?" Optimus asked, knowing it sounded to good to be true.
Scourge knew Optimus would respond that way, as Scourge would have said the same. "I will make you a deal. I give you the key and I join the Autobots, but when the war is over, you belong to me and will come stay on Jungle planet" Scourge replied, a poison pill deal if there ever was one, or so Optimus thought.
"Fine, I will agree to your terms, but I do have one question. Suppose there was a teammate of mine that wants me for a mate as well, will you allow that?" Optimus asked, not knowing if it was true, but feeling compelled to ask.
"Well, if such a bot exists, they will have to prove they are worthy" Scourge replied. Optimus liked the terms even less, but he couldn't allow his men to fight this war without him. Scourge smiled and headed out with Optimus. They were heading to find the other Autobots with only Optimus aware of what a crappy deal he got just to try and save the universe. Would he be betrayed later? He had no idea, but that could wait. For now, the black hole took priority.
