"L- Lesson? That... that was a lesson!?" was all Ratchet could utter. He was a veteran of conflict, make no mistake. At Optimus' side, he had seen and lived through dozens of conflicts. He had treated and experienced all types of injury and trauma. Nothing, however, had prepared him for what Starscream had just inflicted upon him. He felt exhausted, drained. His eyes felt heavy and his posture, once defiant, was slumped and submissive. He thought, for the briefest of moments, of telling Starscream everything. The fabricated story of energon deposits had already done it's work in distracting the bulk of Megatron's forces. He could just end this indignity now. Starscream would know when he told the truth. As quickly as these thoughts occurred to him, they were quashed however.
Never.
His capture was unforeseen and unfortunate, but there was too much at stake on the world below to let slip now. Once Optimus had realised he was missing, he felt sure they would come for him. He had to be resolute. He had to take everything Starscream threw at him. There was no other way. He gritted his teeth. "N-next. L-l-lesson. P-please." he rasped with ragged breath.
Starscream noticed the change in his victim. It excited him. "Yessss" he purred. "Another lesson for you. My slave. My well endowed captive. You'll break eventually. But not before I've had my fun." He grinned as he finished his sentence, one silvery claw rising to his face to slip a stray strand of Ratchet's glistening fluid into his mouth. He was loosing sight of his priorities, he knew that. His personal pleasure shouldn't come above proving his worth, he knew that. It was too much however. The rush of dominance. He needed this. He had needed it for a long time. "But first we will need a change of posture, I think." He reached up, and with a swift flick of his claw, separated the cuffs from the chain that held the hapless autobot's arms above his head. With surprising force, Starscream then grabbed both of Ratchet's wrists and leaped forwards, his legs either side of his captives broad chest, the force of his lunge threw them both back, Starscream pinning Ratchet's arms to the floor, either side of him. All as planned. There was a shrill chirp as the cuffs secured themselves automatically to fastening bolts in the floor, leaving the Autobot hapless and splayed out, completely at the mercy of the winged figure that straddled him. "Now, slave, I've been ever so generous to you." the familiar patronising drawl returned to Starscream's lips. "I've given you so much. It's about time I take something back in return." As he said this, the lithe Decepticon was sliding his aft backwards, rasping metal upon metal as he snaked his rear end down over Ratchet's chest, to his abdomen, until he felt the tip of Ratchet's still erect spike brush against the small of his back. Ratchet could guess what was coming next.
"I must admit, Autobot" growled Starscream, reaching behind himself with one steel tipped claw to brush up and down the length of the member that was now pushing firmly into his back. "I am impressed with you. I'd often wondered what such a... robust specimen would be like. I had no idea it would be this impressive."
"Twisted wretch" came the reply from the stricken prisoner. Then, in another act of defiance: "Does yours not measure up?". If that comment was meant to rile his aggressor, it was unsuccessful. His smile simply widened. "Keep up this level of endurance, Autobot scum, and you may see for yourself." His willfulness seemed to excite Starscream. Ratchet sensed this and braced himself for what was to come. With a whirring click, Starscream's aft port slid open. He raised himself using his hips so the tip of Ratchet's shaft came into contact with the opening, rotating his hips slowly, he teased the end of the spike, drawing more groans from Ratchet and a fresh then trail of fluid seeping from the head. "This is where I take something back, fool." He dropped his weight on to Ratchet's crotch and rammed the throbbing spike deep within his aft.
Both their visions exploded with electric pleasure.
