Vixen loved interfacing; he was the sluttiest Vehicon on the Nemesis sleeping with everyone, rivaling his frienemy, Lock. He wasn't ashamed of his actions. He liked to play. But he was growing bored with the bots he had access to.
The Vehicon exited Megatron's chambers with a sigh. The warlord was one of his favorites, but it was the same mech. Positions changed, activities changed, but Megatron was what he always expected. He needed someone new to play with...that he hadn't already done once. What about an Autobot? Not one rule technically stated he couldn't interface with an Autobot. The rules covered whistleblowing, sabotage, and all that but not sex.
Vixen had to think on that. Arcee and Wheeljack were most likely to kill him, Bumblebee seemed like a young stallion, but Optimus wouldn't approve. Smokescreen, no. Ultra Magnus, no. Bulkhead...big potential but best leave him for a special day. That left Ratchet and Vixen knew nothing about the Autobot medic aside from being said medic. Was he a stunner? Was he a fighter? The mystery of the medic was calling him, and he wanted to know but how exactly was he supposed to get close to him if he's always at the Autobot base? A diversion and sneak into the base? Long shot but plausible and thankfully, he had a bit of leeway with his talents.
Setting up the task was hard, especially not alerting Megatron of his real goal. A few scrubbed lies and some juicy alternate incentive, i.e. an attempt to get rid of the Autobots at last, led to the distraction he needed. His fellow troops charged all the Autobots present, and he watched the Autobots' ground bridge remain open before making his move. He only had some time before it closed so he was going all in.
Running to it, he snuck past everyone and made one faithful leap into the portal as it shrunk. He landed a bit rough but was fine otherwise until he found a blade pointed right at his face.
"I suggest going back where you came from. Allow me to escort you out," Ratchet said.
Vixen scanned the bot and was surprised to find the medic was thick, especially in the thighs and handsome to boot. Move over Knockout, there was a new medic he wanted to play with.
The Vehicon laughed, "Oh, but I'd like to get to know you. Is that knife the only thing big on you?"
Ratchet scowled, "What? Where in that twisted warship did you crawl out of? Are you trying to hit on me? Really?"
"I'm from the fun side. Life is too short so why not have some fun and you, dear Ratchet, are someone of interest. I'll be a good bot, I promise. Cross my spark and hope to die," he laughed, gesturing in mockery. "Unless you don't want me to be."
"You Vehicons are getting stranger by the batch..."
That was a compliment to him. Suddenly, Vixen sat on his calves with his legs spread and his arms poised straight the middle making a small window for his chest. "I'm feeling a bit heated today. Aren't you going to help me, Doctor?"
He caught Ratchet's blush and would have smirked if he could. The Autobot medic was quick to peer around to make sure he was the one being addressed, that this wasn't a dream, as if there was any other doctor in the outpost. When he could confirm there was none, Ratchet approached cautiously.
Vixen merely responded by opening his interface panel to reveal his valve only. "That's where it burns, Doctor."
Ratchet eyed the already wet valve and said, "In order for me to do a proper checkup, you're going to have to get on the berth first."
Vixen obeyed and stood up, fanning himself dramatically like an actor which made Ratchet crack a smile, just what he wanted to see. He sat on the medical berth and placed his pedes on the edge with his legs wide so the good doctor had an excellent view of what he could take if he was bold enough. He saw the medic's servos twitch and he leaned back on his arms to appear more presentable and desperate.
Ratchet kneeled as he said, "First, I need to do a few tests."
"Do whatever you can, Doctor, the pain is unbearable," he mocked.
The Autobot skimmed his fingers over the exterior, pulling the petals of the valve apart. He wondered if Ratchet liked to tease, to draw out the pleasure. Given he was Ratchet's enemy, it made sense that his treatment would be so rough, but he didn't expect the older mech to be so forward when his valve was assaulted by a hungry glossa.
He instinctively tried to close his thighs to trap Ratchet as the glossa wasted no time in prodding his valve entrance, but they were forced still. Ratchet pressed his mouth close, nipping and sucking on the Decepticon as Vixen became vocal in no time. He had been eaten out once by Starscream but never like this. This was feral, and he didn't think a bot like Ratchet would be so passionate.
"D-Doc! Ratchet!" Vixen whined, pressing his back down on the berth and arching as he scraped his claws against his heated abdomen craving more. "Where have you been hiding?"
Ratchet paused to Vixen's dismay before his glossa was replaced with digits. The three digits twisted within as he then said, "I am the Autobot medic. They couldn't replace me if I used my talents elsewhere."
Lucky Autobots. The brag earned him a moan, one that Vixen gave out against his will. The medic's fingers did little to allow him to stay quiet. "A-Ah! Right there!"
Ratchet held a grin watching Vixen rut against his servo. Vixen, on the other hand, loved the stretch and the feeling of the invasive appendages curling against hidden nodes. He left claw marks on the medical berth trying to keep himself steady when he overloaded. It was a hard one, one he wanted to repeat again but the medic had other plans.
"Your vitals are high. Lubricant discharge seems normal, but the pain seems to be resilient. Allow me to try another form of treatment," said Ratchet as he stood and pulled out his digits.
Vixen's breath hitched as Ratchet let out his red and white spike, pumping it with his coated digits to ensure it was partially slick. When it was aligned with his valve, Vixen this time spread himself eagerly. His thighs were gripped when it breached him. He made a small whimper before melting into putty for Ratchet to use at his whim. Megatron was the largest, but Ratchet had an angle to him, one that rubbed his walls the best. Sometimes that was far better.
He was thrust into at a set pace at first. He could tell Ratchet hadn't let anyone in his berth for a while but that made the medic even more controlling, which reflected well in his movements. The servos holding his legs dragged him to meet each rut until Vixen was forced to the hilt. He panted as his systems gave warnings of core temperatures rising and other notifications, none he truly cared about as long as he was on the receiving end getting fragged into the berth.
"Please, Ratchet, ah, please!"
Ratchet grinned, "Do you like being used by enemies more than your own?"
Well, no, Megatron was a fucking awesome lay, but Vixen definitely planned on coming back one day. He said nothing as the spike started getting sloppy, ragged and brutal. Ratchet was chasing his own overload over Vixen's. The concept only heightened his pleasure being used as nothing, but a mere frag doll to the deprived Autobot.
The uncomfortable feeling of being stuffed like a toy, however, did linger as Ratchet's thrusts were outright erratic. Vixen's fluids were being pushed out faster than they could be created and now there was a slight burning feeling. Too much interfacing but not enough steam as he thought he had. But he was too deep in the rabbit hole now, and Ratchet was far too dedicated to make him regret finding him instead. When the medic filled him, Vixen was a bit distraught as he was so used to the common partners being able to match him. He wasn't fully charged himself!
Ratchet raised a brow, a torturously amused brow like he was disappointed in Vixen more so. The Vehicon hated that.
"Is that it?"
The medic cleaned himself before smirking, "Oh, you didn't expect me to give you all that you wanted, did you? You have to earn that. You offered yourself to me to use. You didn't say I had to make you come too."
That stunned Vixen more than anything. No one had ever dared to stop unless he wanted it. Even Megatron would go as long as he presented his aft to the mighty warlord and get some mind-blowing orgasms in return. This Autobot was mocking him! He's still presenting, and all the medic cared about was himself. Nobody made a fool of Vixen like that. He was a slut but damn if he wasn't going to get his due from it.
As Ratchet checked on the status of the battle, Vixen growled and stomped towards him. If he wasn't going to get what he wanted willingly, he wasn't above taking it. The medic seemed to anticipate the Vehicon's greed and grabbed him before he could strike, pinning him to the console with a thigh between the drone's legs. It pressed against the needy, rejuvenating valve and elicited a moan from him.
"You realize you can't always have what you want, right? Why should I do you any favors, Decepticon?"
When Vixen refused to answer now out of spite, he was surprised when Ratchet hiked him to lean against the console and realigned his hardening spike again. He now got an unreadable expression from the Autobot, one that made him curious more than anything. He got his answer when his legs were forced around the medic's hips.
"Don't want to talk now? Fine, I can make you talk. That's why you're here, isn't it?" A thrust inside Vixen had him clawing the console. "I'm not going to give you what you think you want. I'm going to draw this out as long as I can, and you're going to have to deal with that. You came to me after all, and I know a lot more in how to withhold pleasure than simply stopping."
"Fuck you," he muttered as another sharp thrust hit deep just how he liked it.
Ratchet hummed, "That's what I intend to do. You won't overload yet until I use you like you really want. Can't go to the enemy and frag them then leave. That's not how this works, and you are now my prisoner. You can call me your Doctor of Doom."
Vixen kind of hated how turned on he was getting as Ratchet went hard, yet again chasing his own orgasm over the Vehicon's. It was horrible yet he found it poetic. It was certainly a lesson to not venture into Autobot territory ever again. He neared overload by the third time when the Autobots were called back and hidden in Ratchet's berthroom where he was used over and over but was refused his due until his eighth round. He had never been more grateful for an overload in his life.
AN: You can get what you want, but it isn't always what you need. And that's, of course, not getting into the aftermath of everything. Poor Vixen. I also did this to use the "Doctor of Doom" saying too. I had to.
