You loved your two conjunxes oh so dearly. You loved it when they got engrossed in their nerdy science stuff, loved it when they bickered over silly things, loved when the three of you took the time to just talk about the things you enjoy, with mostly you and Brainstorm(really just Brainstorm) talking while Perceptor nodded and smiled. But of course, you also loved the debauched things you and your partners got up to in berth.
"Mmhhmm...Percyyy," Brainstorm whimpered into the open-mouthed kiss he was sharing with his conjunx. "Hmmnn..." Percy moaned into the kiss as well, lightly fondling the jet's wings. You were behind Brainstorm, watching carefully as your lovers sloppily made out. It was so cute seeing the two of them all over each other like this. While Stormy was busy kissing Perceptor, he pushed back his leaking valve against your spike panel, wordlessly begging for you to fuck him.
Taking the hint, you released your spike. It was already pressurized-- how could it not be? You moved yourself so that your chest was flush against Stormy's wings and grabbed him by the hips. He shivered, knowing what you were planning to do and opened his legs wider so he could properly receive you. "N-nhhn, [n-name], pl-- MhhnN! Nghh..." Whatever Brainstorm was trying to tell you was cut off short when Percy grabbed his chin and pushed his glossa into his mouth to shut him up.
Brainstorm squirmed in Percy's hold; how long were you going to wait before spiking him? He wanted to whine in frustration but he knew that acting out would only cause him to have to wait even longer. Finally though, he could feel your thick spike against his valve entrance an he whimpered in anticipation. "Stormy, you mind opening up your chestplate for me? I think Percy wants to see your cute tits," you croon into the jet's audials. He immediately released his refineries from there confinements and was taken aback by how quick you were to take on into your servo.
"Your tits are so cute Stormy! Too bad they're so small though," you gave him a fake pout as you rolled his nozzle between your digits. He let out a small squeak from your touch and your words-- his tits weren't that small! Though clearly, you didn't care about what your conjunx thought. You were to busy groping him and getting him worked up . "Percyyy, don't you wanna feel him up too?" you asked the sniper in an overly innocent tone. Having recently just been a viewer, he almost seemed surprised that you acknowledged him again, too busy admiring the two of you. Despite his slight surprise, he took Stormy's other breast and fitted his mouth over the nozzle.
"HnngGH! P-Percy, I-- Ah! Ahnn...n-no..." Brainstorm weakly protested against the constant stimulation of his tits. It was too much! Perceptor was suckling on his nozzle like his life depended on it and you were behind him cruelly pinching his nozzle while you nipped his wings. Worst of all, he could feel your still-pressurized spike rubbing against his valve, a constant reminder of how empty he felt. It was no surprise that Brainstorm overloaded so quick, letting an overstimulated mewl as his golden optics screwed shut. Even through his overload the two of you still didn't let up on. He kept futilely squirming in yours and Percy's grip, letting out more cute whimpers as he silently begs for you to finally fuck him.
Despite how badly he wanted you to spike him, he never actually expected you to shove your spike into him with no warning. "Guh---*Kzzh*--" Stormy's optics widened as he spat out static. He wasn't even close to being ready for your spike to impale him so quickly! His optics unfocused as he trembled through another overload just from you putting your spike into him. In front of him, Percy whined, not sure if he wanted to be the one spiking Brainstorm or to be the one you were fucking. "Don't worry sweetspark," you cooed to Percy, reaching past Brainstorm's frame and cupping his face into your free servo. "I'll give you what you want soon." And with that, you gripped Brainstorm's hips and started to harshly fuck into him.
"HaAHH! Unghh! [N-Name]! Pl-- Oh! Oohhh!" Stormy's spinal strut arched into you as you fucked his valve with a punishing pace. He could feel every bump and ridge on your spike dragging on all his sensitive node clusters and it was driving him mad, despite you barely starting what you had planned for him. Even while you were fucking Stormy's valve, you still had one servo on his breast, relentlessly feeling up the soft protometal and Percy had not yet let up on suckling Stormy's nozzle, as if he was desperate for energon to come out. Perceptor's panels were even released, his spike rutting on Brainstorm's midsection as his valve hidden from your view leaked lubricants.
Stormy overloaded a second time, even harder than the last as his vocalizer let out a loud squeal; barley anytime had passed since you shoved your spike into him yet he was cumming again, his pussy squirting all over your spike making it easier to make your spike kiss his ceiling node. "Ungh, hahhnn! Mnghh-- t-too mu-ugh, o-ohh!" Stormy could barely even form words from the brutal pounding he was receiving, the words dying on his glossa as he was jostled from each of your punishing thrusts. He thought that he might have even overloaded for a third time but it was so hard to think clearly through the pleasure washing over him. "Hey Percy, I think Stormy's wet enough to fit the both of us." Your words brought Brainstorm a bit out of his pleasured daze. The both of you were going to be inside of him? Perceptor's eyes widened before he positioned his spike against the jet's wet heat.
Yes, yes, yes, yes, ye-- A smile formed on Brainstorm's faceplate as he felt Percy's spike touch the entrance of his valve. He had hoping that this would happen since the three of you entered the berth and now he was finally getting his wish: he wanted to be split open on the two of yours' spikes and fucked 'till his circuits fried. Perceptor groaned as he pushed himself into Brainstorm's valve-- it was so tight! Even with all the extra lubricant the two of you had created it was still a tight fit for Percy, making the mech have to put more force into his thrusts, which only made Stormy wail louder.
At last, the two of you were snugly fit into your conjunx's valve. Stormy had a faraway look in his optics, like he was barely hanging on. His wings were trembling...matter of fact. his whole frame was trembling. His mouth was stretched open into a small "o", oral fluids seeping through his cheek cabling. He looked like a lewd mess and the two of you hadn't even started fucking him yet. Without any warning, you began to thrust into the plush valve enveloping your spike and Perceptor took it as an invitation to start moving as well.
"Guh--UNGHH---*Kzzhh*---AHH! *Ghzzk*--" Brainstorm's cries were so loud now that they were mostly being taken up by static. You were so glad that you soundproofed your habsuite so long ago. It wasn't easy for the both of you to efficiently fuck Stormy's valve with the way that his callipers kept cycling down on both the spikes stuffing him absolutely full. Stormy's optics began to roll into the back of his helm as his frame was rocked alongside the powerful thrusts of both you and Perceptor. While he let out overstimulated wails from the spikes dragging over his nodes and striking his ceiling node, he could feel his processor power slipping aways from him; it was so hard to think while the two of you were fucking his leg struts numb! Processor fried from spike, he felt his gestation chamber open up, allowing the spikes inside of him access to his forge.
Percy was the first to overload, letting out a loud cry as he spilled into Brainstorm's awaiting chamber. His overload caused Brainstorm to trip into his...fourth? Fifth overload? He wasn't even sure anymore, all he knew was that he might not ever stop overloading again. That was a thought that made him giggle a bit through his staticky mewls. It was those fucked silly giggles that made you overload last and spill into Stormy's gestation chamber. Stormy spit out static as he felt the rush of your combined transfluid fill up his valve and even escape a bit. He felt so...full. It was the thought of the transfluid still filling up his pussy that made him let out a few fucked silly giggles, twitching from the aftershocks of his intense overloads. Not a single thought was occupying his processor besides the spikes filling him up and making him all warm inside. Even though you had slightly depressurized and you were sure Percy had too, you still wanted to savour the tightness of your conjunx's valve. Just like that, the three of you laid in one berth, cuddling each other as you came down from your highs. You wouldn't be able to stay like that forever though, but it was nice to feel each other's warmth as you rested together.
