He heard Knockout from time to time. It was expected given it was, well, Knockout. Shockwave stayed away from that type of stuff with it not being crucial to anything he needed done, but there were plenty of times he grew curious what or who Knockout was doing.
Maybe this was a bit rude of him, but he had a system calculator for how Knockout's encounters were. The louder he was, the better the interface. The longer it was, calculated by when someone entered and left, the higher Knockout's sex drive was until he got bored of his current partner. And then there were common to uncommon lays which determined who he targeted and why.
Common Vehicons and other lower officials meant Knockout was just in the mood to take anyone and that was usually on the lower ratio of pleasure but occasionally had plenty of noise, so they satisfied him enough. Breakdown was the most common, but Shockwave assumed him having gotten used to the mech so much that he was not what Knockout wanted in his more promiscuous, explorative phases. Soundwave and Megatron made Knockout scream the loudest; other commanders ranged similar, but the meetings lasted the shortest. That determined Knockout was satisfied faster. The only bot he never got with was Shockwave himself.
Was there an urge to ever meet with the medic? Not really. There was a thought process, but he just never bothered to go through with it. It wasn't a loss to him. Did Knockout ever care he was the only mech unavailable to him? He doubted it. So many Decepticons to choose from and not enough time in the day to fuck them. Knockout certainly had more than enough spike and valve to keep him busy.
At least that's what Shockwave thought. The scientist started noticing though partners were coming in and out fast, some looked disappointed and seldom was there any noise. Now, that was strange. It wasn't Shockwave's place to pry but no noise in over a week with his base lab so close to the medbay and Knockout's private quarters made him very suspicious. Granted, the quiet atmosphere was nice but way too strange. It felt...wrong.
Shockwave finally got the sense to go over to the medic's quarters. He heard soft moans but nowhere close to any of the noises he was accustomed to. No other sounds and no recent visitors, so that confirmed Knockout was alone. He knew the passcode to Knockout's quarters. Everyone did. When he stepped in though, he was a little bewildered at what he found.
Knockout was recording himself laying on his back and had a vibrating toy plunged into his petite, well-lubricated valve facing the playback camera. There was a monitor on the screen beside it, a display for the power of the vibrations. Knockout looked to the side towards him as the door closed but he didn't look upset, rather somewhat surprised given Shockwave had no place in his sanctuary. The purple mech perked up when the vibrator spiked in power, and he heard Knockout's inappropriate gasp.
He didn't know truly why he just stood there watching. It was one thing to hear Knockout's activities, but it was another thing to behold them himself. Shockwave crept closer looking at the disgusting, arousing scene in front of him before Knockout exploded with a cheap overload. It didn't sound as enthusiastic as Shockwave was used to hearing.
When Knockout turned the camera off and the controls to the vibrator but left it physically in, Shockwave asked disgruntled, "I...I came here to check if you were alright. You have been, er, quiet recently."
Knockout sat on his berth casually, not even bothering to hide his valve. Shockwave respected that because it was his room...
"I just haven't been feeling like physical company. But these toys aren't really doing it the same as a real spike," replied the medic. "It feels decently great, but it would feel better with a real bot around. Everyone wants the same old position, same old frag and go. I need a new flavor. And I thought I could achieve that with recording my habits but not the same either."
So, Knockout was bored. That was a first as far as he knew. Shockwave peered at the monitor awaiting new use and noticed a manual remote for what he presumed was the toy if it wasn't automatic.
"No one satisfies you right now?"
"Nope," Knockout huffed before raising a brow in Shockwave's direction. "Why do you care so much? I'm flattered, don't get me wrong, but isn't this not your forte?"
Shockwave muttered, "Doesn't mean I can't be curious as to my neighboring associate's health."
A widening smile played on Knockout's faceplates and Shockwave only knew that look when he was horny. The scientist debated whether or not he should leave, but he found himself staring down at Knockout's spread legs that were now fully open with the toy present. His systems warmed as he thought about maybe finally getting a taste of the doctor. There was no question in his mind Knockout was hot.
The medic purred, "Well, I'm still feeling a little...tight around this area. Can you give me a checkup, doctor?"
Shockwave's audial fins twitched with faint zealous arousal. Why not? "I suppose you are overdue for one."
He grabbed the remote and turned the vibrator on to see Knockout's faceplates blush and bit his lip when a faint rumble was present. Shockwave was more of a science doctor than medical so naturally, his functional job was experimentation...and ramping up the power to see how it affected the medic was just that. He watched with utmost attention seeing Knockout whimper, leaning on his arms behind him and arched to roll his hips as the vibrator tore up his valve leaving lubricant to dribble down onto the edge of the berth. It was just as pretty as the bot it came from.
"It looks like your valve is producing the proper fluids, but perhaps an inspection of the interior walls is required to make sure," Shockwave mused darkly as he shadowed Knockout gazing up at him submissively.
He kept the vibrator going, disposing of the remote to the side and pressed Knockout's needy valve to his spike cover, relishing the sudden residual effects echoing through him as well. It indeed felt great as Knockout described. His panel was trying to open on its own from the rush of pleasure. Meanwhile, he just rocked against the gold detailed valve to make the medic hump him like the slut he was.
Knockout mewled at Shockwave's encouragement, but the latter could tell he wanted something a bit more than just a surface to his succulent equipment against. Shockwave was just delaying it because of the toy resonating through his own array. He groaned seeing the medic orgasming with a shout. That was a sign it was time for the big gun.
His spike caused Knockout to have lustful stars in his optics and all but asked innocently, "Where have you been hiding, big boy?"
"Consider yourself a special case," Shockwave chuckled.
The vibrator was briefly brought out so Shockwave could push in his spike in the gluttonous valve that was made by Primus. Knockout made the first loud cry from the intrusion in what felt like forever since Shockwave last heard it over a week ago. He pushed in the vibrator alongside his spike and both bots shuttered.
"Y-Yes, ah!" The little sounds Knockout made were nothing compared to what Shockwave was going to make him yell.
What was supposed to be just a simple interface session turned into one of desperation and long depravity cured. Growing shouts calling Shockwave's name were loud enough to echo down the hall to any Decepticon nearby. The berth's stands were creaking from the force.
Shockwave huffed at the mix of the vibrator on high and the valve he was all but destroying in his race to make Knockout forget all about his past lovers. A sense of entitlement overtook Shockwave. He was the one who was making the medic scream now. Hearing it through the walls was always an annoyance but hearing it up front with him at the reins was how it should be.
Knockout had strands of oral fluid building his mouth from all the panting with his glossa out and his optics half-open with reformed desire. It only made Shockwave more aggressive in taming him for himself.
The spike pumped out plenty of lubricant, more each thrust it seemed. Knockout really was a slut, a fantastic one but one nevertheless. It certainly didn't bother Shockwave anymore not that he had an idea just how much Knockout liked being pounded. The vibrator just was there to spice things up, not a regrettable choice in the slightest.
"S-Shockwave, please, ah-ah f-oh! Frag me! YES!"
He couldn't say no to that. It was far too adorable. Shockwave felt the vibrator through every sensor on his spike that made him shake amid the frantic thrusts to completion. He was spiraling in a freefall, clutching the medic's waist so he could do nothing by ram him. He just needed to make sure Knockout-
"AH! AH! SHO-AH!"
As Knockout had a mind-numbing orgasm, Shockwave chased his vigorously. Hearing his name yelled out for Primus to hear sent him over the edge in record time along with the vibrator giving no mercy. He stopped on a final thrust and partially unloaded into Knockout, dragging his spike out to leave the rest to gravity onto the floor.
Shockwave peered at his lay upon recovery and noted how scandalously happy Knockout was, valve in view with two variants of liquid running down swollen folds and legs up and bent like a desirable harlot. His servos were on his chest and abdomen with his optics closed in sedated lust. He was beautiful. When he looked Shockwave's way still with half-lidded optics, the scientist's spark skipped a beat. The vibrator was still going pushed inside farther in their rut and leaving ripples that made Knockout give small, content moans to.
"Had I known you to be quite the lover, Shockwave, I would have paid a visit to your lab," the cherry red mech purred seductively.
Shockwave was a little out of breath and replied, "Maybe I will do a secondary checkup in the future..."
"Do hurry back, baby."
Knockout softly reached between his legs and gently stroked his sore valve. Shockwave tried to ignore it to leave but midway to the exit, he paused. He turned around to glance again at the smaller mech laying there open and willing, enjoying that vibrator as a comforting decompressor. Nothing was stopping Shockwave from going again, and he very much wanted to. Between the door and the wanton bot on the berth, Shockwave had a decision to make.
Whipping around, Shockwave approached Knockout again. The medic was slightly surprised by this but grew fond and mewled in delight of another few rounds. Shockwave wouldn't disappoint. He never did in anything before and he wouldn't now.
The halls and neighboring rooms heard them, heard Knockout's calls rising loud and clear just like before. Shockwave made sure they wouldn't be silent for a long while.
AN: A little ooc because it's kind of hard to get these two together considering. Was Knockout lying to lure Shockwave or genuine? That's up for debate.
