Peace and quiet are forever in short supply around the Ark. There’s always something going on, and there’s barely any space as it is, so trying to find an opportunity to be alone is as difficult as keeping his paint immaculate.
Luck, however, is on Sunstreaker’s side. Because Sideswipe is off doing something he’s being particularly secretive about, and Sunstreaker has their shared quarters all to himself. There’s no one in the rooms to either side of theirs, and most of the other Autobots are out doing chores or performing their duties or indulging in their hobbies.
It’s nice and quiet and perfect, and Sunstreaker vents a little sigh as he sinks into the plush couch he and Sideswipe built out of scrap. He mindlessly doodles on one of his sketch pads, nothing in particular, just vague lines and colors to keep his fingers occupied while his processor wanders. He’s got the stereo crooning a soft, wordless tune, and the day honestly couldn’t get any more perfect.
Which is why, of course, the door slides open with a rickety creak, and Sideswipe comes strolling inside, having the audacity to whistle. He’s grinning, a bounce in his step, and while a happy Sideswipe is a handsome Sideswipe, Sunstreaker is disappointed his solitude has come to an end.
There’s something in Sideswipe’s field, in his side of the bond carefully shielded from Sunstreaker, that speaks of mischief. Well, Sunstreaker wants no part of mischief today, thank you very much. He prepares a refusal and has it ready on the tip of his glossa.
Sideswipe hums a happy trio of notes when he spots Sunstreaker and grabs one of the chairs they usually have in front of the game station. He drags it closer, two of the legs scraping over the floor, and plants it in front of Sunstreaker. Backward, of course, because this is Sideswipe.
Sunstreaker’s hackles raise.
“Hey, Sunny?” Sideswipe prompts as he drops down into the chair and rests his arms across the back of it, plopping his chin down on his wrists.
Sunstreaker’s in enough of a good mood that he allows the nickname. Just this once. Though the mischief in Sideswipe’s actions threatens to sour his happiness and curdle it into irritation.
“You know I love you, right?” Sideswipe says conversationally, and there’s just enough of something in his tone to disprove his innocence.
Sunstreaker scowls. Sometimes, Sideswipe says those kinds of things because he thinks Sunstreaker needs to hear it, and sometimes, Sunstreaker does. It warms his spark and makes him tingly, and then all he wants to do is snuggle Sideswipe for a few hours.
But also, sometimes Sideswipe says it because he’s Up To Something ™ and he’s trying to connive Sunstreaker into playing along. Sunstreaker usually ends up agreeing because he can never resist Sideswipe when he’s being cute and charming and lovable.
“I don’t have time for a prank, Sideswipe,” Sunstreaker says.
“I’m being serious here,” Sideswipe insists, attempting to sound earnest.
It still sounds fake.
Sunstreaker snorts. “Right.” He turns his attention back to his random doodles. You know, there might be something to the geometric lines and empty space. Perhaps if he filled it in with color, it might be worthwhile.
Fingers close around the top of his sketchpad, tilting it down and forcing Sunstreaker’s gaze away from it. “Hey,” he repeats. “I love you.” This time, he manages to sound serious.
Sunstreaker looks at his twin, and Sideswipe looks serious, too. The smile on his lips is soft and genuine. The mischief in his field is gone. So this isn’t about a prank.
“And there’s nothing you could want from me that’ll change that,” Sideswipe adds, so earnest it bleeds from his seams.
Sunstreaker’s optics narrow even as his spark starts a weird off-beat rhythm in his chassis. There’s something going on here, and he’s not sure what it is. He’s also not sure he wants to know.
“Where are you going with this?”
Sideswipe’s fingers slide free of the datapad. He grips the back of the chair and starts to rock back and forth in it. “Me and Ratchet both,” he says cryptically. Sometimes he can take forever to get to a point. Especially if he thinks Sunstreaker is going to react poorly to it. “You can ask us anything.”
“Okay…” Sunstreaker peers at his twin, but can’t figure out what he’s trying to say. Still, he supposes it’s nice to know. Maybe Sideswipe is just in one of those moods where he thinks Sunstreaker needs a reminder about how he feels. Sides just knows these things sometimes. Even before Sunstreaker does.
“Right.” Sideswipe nods like he’s solved some kind of puzzle before one hand scrubs the back of his head. “So, uh, is there anything you want to ask? Me? Us? Together?”
Sunstreaker vents a sigh. Whatever this is, Sideswipe isn’t going to let this go anytime soon, which means the quicker Sunstreaker makes him talk, the quicker he can get back to sketching.
He taps the end of his stylus against the datapad. “Stop fishing and say what you mean, Sideswipe,” he says. “Because I have no idea what you’re talking about.” He’d been enjoying his rare peace and quiet.
Sideswipe drags in a big vent and then blurts out, “Kink!” before he rocks on his chair and his little smile turns into a broader grin. “Specifically a messy one you’re interested in. Not that I peeked or anything, but the last couple of times we merged, I got a whiff, and it keeps getting stronger.”
Heat floods Sunstreaker’s face. If Sideswipe caught on through one of their merges, it must have been one of Sunstreaker’s stronger and more frequent fantasies. The ones he buries deep specifically so his brother and their lover don’t find out. Sunstreaker doesn’t even know if he’s ready to admit them to himself, much less his partners.
He’s afraid of what they’ll say when they find out. He fears what it means about him to admit these… these odd kinks. Oh sure, Ratchet and Sideswipe claim he can ask for anything, but they can’t mean it. Once they find out all the dirty, twisted things occupying Sunstreaker’s fantasies, they’ll change their minds fast. They’ll change how they feel about him, too. They’ll see him for the depraved creature he is.
Sunstreaker frantically searches for a way out of this. He tries to think of a denial – which never works when one of your lovers is the other half of your spark. He tries to think of a misdirection, but he’s spent too much time thinking to brush it off. He’s caught, he knows he is, and the energon in his tank starts to curdle.
Sideswipe rubs the back of his head again. “I told Ratch, by the way, and we’ve been waiting for you to bring it up yourself but…” Sideswipe shrugs, his grin sheepish. “You haven’t.”
“Your point?” Sunstreaker asks, his mouth dry and his intake overtaken by a huge lump.
“We’re willing.” The chair rocks closer, and the touch of Sideswipe’s field to his is both cautious and gentle. “If it’s something you actually want, I mean.”
Which fantasy, Sunstreaker wonders. Which illicit desire had Sideswipe seen? Surely, not the darkest of them, the dirtiest. No way would Sideswipe be that eager.
Sideswipe’s voice drops into a lower register then, one that always makes something tighten inside Sunstreaker and bloom with heat. “We thought, you know, we’d tie you down, maybe get out that vibe you like.” He pauses, glossa sweeping over his lips. “Then we’d go until you were so wet, so covered in us, that you can’t even remember your name.”
Sunstreaker’s ventilations turn shallow. His optics spiral wider as the heat in his face turns into an inferno. He thinks he knows which fantasy Sideswipe saw, and it’s definitely one of the tamer ones, which is a relief. He licks his lips with a dry glossa, however, because now the possibilities are spinning inside of him.
“Does that sound like something you want?” Sideswipe asks, so close now Sunstreaker can feel the wisp of his ex-vents, like hot puffs against his armor.
“Yes,” Sunstreaker manages, through static and a tight intake, fantasies spiraling free inside of him, the idea of so much pleasure racing through his system.
“Awesome!” Sideswipe bounces up from the chair, as full of energy as ever, and brushes his lips over Sunstreaker’s forehead. “Then don’t worry about a thing, bro. Me and Ratch’ll take care of everything.”
Sideswipe’s field is a tickling caress pouring over Sunstreaker’s sensitive derma. “Ratchet and I,” he corrects, but it sounds distant to him, compared to the pounding in his audials.
Ratchet and Sideswipe both. Taking him. Filling him with transfluid. Using him. Over and over and over…
Sideswipe snorts and taps Sunstreaker’s nasal ridge. “You’re adorable,” he says, and with a wiggle of his fingers, strides toward the door. “See you tonight!”
With that, Sideswipe flounces out of the room, leaving Sunstreaker to stew in his arousal and anticipation. No doubt he’s gone to inform Ratchet of their plans for the evening, and all Sunstreaker can do is stare blankly at his doodles. His engine purrs at the mere thought of what his twin has in store for him.
He’s beyond thrilled that they are willing to indulge in one of his fantasies. And it’s a relief Sideswipe hadn’t stumbled into one of the weirder ones. Clearly, he needs to batten the hatches and firm up his firewalls if he’s going to keep those fantasies from his brother. At least until Sunstreaker is willing to admit them anyway.
Tonight is going to be great, Sunstraeker tells himself, and puts down the datapad. He has to be presentable. Which means it’s time for a deep wash, repaint, and wax. His lovers deserve the best from him.
In between wax layer three and the final layer, Sunstreaker’s comm pings him with an incoming message. He accepts the mail as he works on his right shinguard, smoothing the wax over and over into his armor until it is a lustrous, touchable gold.
There’s not much to it. The message is from Sideswipe and all it gives it a place – Ratchet’s quarters – and a time. Sunstreaker has an hour to finish his waxing and grab a cube to refuel before he’s supposed to show up.
He’s simultaneously giddy and nervous when the time arrives, and he stands outside the door, shifting from foot to foot. He doesn’t even have to knock because Sideswipe opens the door before he can lift his hand. Spark bonds are a convenient thing.
Sideswipe grins and snatches Sunstreaker, yanking him into the room and into a fierce kiss that tastes of solar-grade and sweet jellies. Sunstreaker stumbles against his twin, hands flailing at nothing, even as he relents, mouth opening to the hungry press of Sideswipe’s glossa. Sunstreaker moans, melting against his twin, optics half-shuttering, only barely registering the noise of the door sliding shut behind him.
Sideswipe’s hands caress his sides before he pulls out of the kiss with a light nip. “Hey, bro,” he says, brushing the tip of his nasal ridge against Sunstreaker’s. “Fancy meeting you here.”
Sunstreaker barks a laugh. Primus, his brother is an idiot. He loves the goof so much.
Movement in his periphery makes Sunstreaker tense, until his threat protocols recognize the blur of white and red paint.
“Welcome to the party,” Ratchet says.
Sunstreaker has a moment before he’s spun out of Sideswipe’s embrace and into Ratchet’s, the medic sealing his lips over Sunstreaker’s in a scorching kiss, taking and claiming all at once.
Sunstreaker outright whimpers, clutching at Ratchet’s shoulders, arousal pooling into a hot throb in his belly. Ratchet’s field is like a dozen tiny fingers stroking over his armor, and Sunstreaker’s spike throbs.
Glossa and denta taste him all at once before Ratchet sets him free. Sunstreaker staggers, like he can’t get his tires beneath him, and then Sideswipe is there, hands on Sunstreaker’s cheeks, tugging him into another delicious kiss. His lips are warm and tender, and more heat seeps into Sunstreaker’s frame.
He sags, knees wobbling, until Ratchet is there behind him, nuzzling the back of his head, hands stroking over his armor. His fingers are light on Sunstreaker’s seams, his palms a soft sweep against gold plating.
Sunstreaker moans, dizzy. He hadn’t expected this. He thought they’d get right to the kink and the fragging. But this feels like they’ve been waiting for him all day and are happy to see him. Like their day isn’t complete until he’s been in their arms.
“You look gorgeous, Sunstreaker,” Ratchet murmurs against the back of his audial, his rough voice resonating through Sunstreaker’s processor.
Sunstreaker hums into the kiss. Sideswipe draws back, leaving little parting licks over Sunstreaker’s lips, grinning with pride at himself.
“You definitely do,” he says, and brushes the tips of their noses together. “Love it when you pretty yourself up for us.”
“I always look good,” Sunstreaker retorts, but it’s hard to hold on to his indignant tone when Sideswipe is looking at him like that. His face heats, and he looks away. “So, uh, now what?”
Ratchet draws away from behind him, leaving Sunstreaker’s back chilly, but only so he can step into view. He twirls something around his fingers, which Sunstreaker can’t identify until they settle with a clank of metal on metal.
“Now we use these, if you want,” he says with a smile wicked enough to rival Sideswipe’s.
His twin can get quite creative, but Ratchet is downright sneaky, and damn good at turning Sideswipe’s little prompts into something debauched and delicious.
Sunstreaker eyes the cuffs with nothing short of lust. If anyone else had suggested it, he’d be out the door in a flash. But he trusts Ratchet, and he definitely trusts Sideswipe, and the idea of putting his trust in their hands, letting them have their wicked way with him, it makes his engine rev.
He manages a nod, his optics glazing over as he imagines what all they’re going to do to him. He has so many fantasies, so many things he wants to experience. He feels like someone’s laid out a buffet of sweets in front of him and told him to have as much as he wants.
“I thought you might,” Ratchet murmurs and takes Sunstreaker’s hand, giving him a light pull toward the berth. “Want to be on your back or your front?”
Ratchet always asks. Every time. Like he knows he needs to. Sideswipe knows, of course, because he can sense the anxiety in Sunstreaker’s spark. But Ratchet has figured it out, and that he’s paid that much attention makes something inside Sunstreaker go warm and liquid.
“Back,” Sunstreaker answers. He wants to be able to see them, to watch their faces.
“Great choice, bro.” Sideswipe appears with another set of cuffs and a few loops of chain. “Now we can see everything, too.”
Heat makes Sunstreaker feel like his face is glowing, but he lets them arrange him on the berth, arousal growing heavier and heavier inside of him. His spike demands to be freed, even as his valve lubricates, fluid pooling against his panel. He waits for the plan and denies both requests.
They guide him onto his back and cuff his wrists, pinning his arms above his head. He’s got enough slack that he could get some inertia and break free if he wants, not that he does. The consideration, however, is welcome.
Sideswipe climbs on the berth, kisses him long and deep, making little noises of delight in his intake. He strokes over Sunstreaker’s belly, teasing into ticklish seams, and Sunstreaker squirms. Idiot. Sideswipe’s always like this.
Ratchet tugs Sunstreaker’s aft to the edge of the berth, his knees dangling freely, until cuffs clamp about his ankles. Sideswipe takes the chance to nuzzle into Sunstreaker’s intake, lips and denta leaving sharp nips that make Sunstreaker squirm. He hears a noise, a low and quiet drone, and realize that it’s him, moaning.
He feels dizzy, their fields pressing against his, filling in the nooks and crannies. It’s more than he could have hoped for.
Chains rattle as they are drawn taut. His legs are pulled open, thighs parted to leave ample room for Sideswipe or Ratchet to fit between them, but there’s enough slack he’s not immobile. He’s spread open for their enjoyment, and his valve throbs at the thought.
Sunstreaker works his intake, his vents spinning faster. Especially as Sideswipe sits him up and wedges a pillow behind his upper back, tilting him so that he can see everything they’re going to do to him.
Ratchet presses a kiss to the inside of his thigh, and Sunstreaker moans. His legs tremble as the hot wash of Ratchet’s ex-vent teases his cables. Fingers flirt over his valve panel, and it takes all Sunstreaker has not to pop open then and there. Anticipation coils inside of him like a blaster prepped to fire.
“There’s one more accessory.” Ratchet straightens, one hand stroking Sunstreaker’s thigh as the other digs around in his subspace. He pulls out a small, circular object and taps Sunstreaker’s spike panel. “This is to make sure that the only way you can overload is through your valve. That okay?”
Sunstreaker’s moan is outright guttural. His hips jutter upward as best they can, though he can’t get any leverage. Oh, yes, please.
“Words, Sunny,” Ratchet reminds him.
Sunstreaker sucks in a heavy vent, tries to focus through the need sluicing charge in his lines. “Yes,” he grinds out and turns his head toward Sideswipe, seeking out a kiss. “Please.”
“Then open up.” Ratchet’s fingers slide over his panel, and Sunstreaker quickly obeys, his spike surging free with embarrassing eagerness.
Or at least he would’ve been embarrassed, if Ratchet hadn’t made an approving noise before fondling Sunstreaker’s spike with obvious appreciation. He rubs a finger over the sensitive crown, teasing the transfluid slit, and Sunstreaker makes a noise in his intake, hips rocking upward.
“You’re so sexy,” Sideswipe murmurs as he nuzzles into Sunstreaker’s intake, breathing hot and humid over his cables. “Love how you just surrender for us.”
Sunstreaker licks his lips. He opens his mouth but all that emerges is a crackle of static as Ratchet carefully and gently eases the cap over Sunstreaker’s spike. A dab of medical glue holds it in place. There must be some kind of circuitry in the cap because Sunstreaker’s spike starts to depressurize, and Ratchet guides it back into his sheath.
“Close up,” Ratchet says.
Sunstreaker obeys with a moan. His spike feels full and heavy behind his panel. Like it’s pressurized to fill every available inch within him, and nothing more. There’s a quiet click as the cap magnetizes to his panel. It won’t be opening anytime soon, not without Ratchet’s help.
Something closer to a whine spills out of Sunstreaker’s intake. His valve throbs harder, panel snapping aside, suddenly desperate for contact. He wants Ratchet inside of him. Or Sideswipe. Or both. He wants something touching his eager nodes, feeding the need gnawing at his spark.
“This isn’t a scene.” Ratchet’s voice tugs Sunstreaker’s awareness back outward, even as his fingers gently stroke around Sunstreaker’s valve rim, teasing the outer sensory clusters. “But if you need us to stop or it gets to be too much, just say so.”
“Like a safeword?” Sunstreaker asks. It’s getting hard to focus with the need pulsing through his synapses.
Ratchet’s fingers keep stroking around his valve, teasing the flexible rim, dancing over his cluster of sensory nodes, making Sunstreaker tingle. “Stop should be enough, but if it makes you feel better to have a safe word, how about daffodil?”
“Because you’re a pretty flower,” Sideswipe purrs with a laugh. His hand smooths over Sunstreaker’s belly, and the stroke of it sends tingles up Sunstreaker’s backstrut. “I like it.”
“Daffodil,” Sunstreaker echoes. His glossa sweeps over his lips as he takes in the sheer want on Ratchet’s face. “If I want you to stop.”
“Yes.” Ratchet’s thumb circles his anterior node slowly, and Sunstreaker’s hips rock into the touch, his entire array throbbing as charge crackles through his lines. “We’re going to frag you, Sunstreaker. Over and over again. We’re going to fill you with our transfluid while you overload so many times, you don’t know where one ends and the other begins. Is that alright?”
Sunstreaker’s head tips back, his mouth open on a gasp. All he can focus on is that steady circling and the pressure building behind it. The sharp bursts of pleasure volleying in his node, and the building need to overload. Sideswipe’s mouth is like fire on his intake, and their fields are a double-embrace he doesn’t want to escape.
“Sunny,” Sideswipe murmurs as he strokes over Sunstreaker’s closed spike panel. “You have to use your words.”
Sunstreaker whines, his hips rocking up into his partner’s touch. “Y-yes,” he gasps out, processor spinning, lubricant steadily seeping from his valve.
“Good,” Ratchet purrs. His hand vanishes from Sunstreaker’s valve, and Sunstreaker whimpers in protest, until he feels the pressure of a spike against his rim.
He gasps an encouragement, hands curling into fists, frame straining toward the grip on his hips, one damp and one not. His thoughts are spinning, spinning, his valve rippling frantically. Ratchet slides into him, hot and firm, so slow, and Sunstreaker keens, backstrut arching, as overload spills over him in a hot, crackling fire.
His noises are swallowed by Sideswipe’s mouth, his brother rubbing against his side, hands everywhere. His valve clutches at Ratchet’s spike, charge rushing out, and he distantly hears Ratchet suck in a vent of delight. The hands on his hips tighten, and Sunstreaker’s spark flares, pleasure making sparks dance in his vision.
Ratchet bottoms out and grinds, the pressure of his array against Sunstreaker’s rim forcing out a moan. Sunstreaker bucks up against Ratchet, and the chains rattle, pleasure simmering inside of him, with no chance to cool from the overload.
“Primus, you’re gorgeous,” Sideswipe murmurs as he rains kisses all over Sunstreaker, his hands stroking and touching, caressing every inch within reach. “Look at you, overloading for us, making all these yummy noises.”
Sunstreaker moans and turns his head, trying to capture Sideswipe’s lip, and Sideswipe obliges, kissing him soft and deep. Ratchet starts to move, his spike gliding in and out of Sunstreaker’s valve, reigniting nodes now sensitive from the first overload. His hands tighten around Sunstreaker’s hips, pushing and pulling him onto Ratchet’s spike, each grind so deep against his ceiling node.
Ratchet’s already thick and hot. Charge crackles around his spike, nipping at Sunstreaker’s internal nodes. He can feel the burning wash of Ratchet’s ex-vents, and the need yawing in Ratchet’s field.
Sunstreaker tries to pull his legs in closer, clamp them around Ratchet’s waist, but the chains bring him up short. He groans at the slight resistance of the chains. He’s not helpless, but he is trapped, and at the mercy of his lovers. The idea is intoxicating because they’re safe.
The crackling wash of Ratchet’s overload is almost a surprise, given Ratchet’s usual stamina. Or maybe it is intentional because of their plans for the evening. Sunstreaker shivers as Ratchet’s transfluid paints his valve, and Sideswipe nips his lips.
“Oh, Ratchet’s done,” he says against Sunstreaker’s lips. “My turn now.”
“Until it’s mine again,” Ratchet says with a little laugh. He withdraws slowly, still firm, his spike dragging long and slow over Sunstreaker’s nodes. “There’s one more accessory we need, too.”
“Yeah, I know.” Sideswipe squirms away from Sunstreaker, leaving him feeling a bit cold and abandoned on the berth, at least until Sideswipe notches between his thighs and moves into Sunstreaker with no fanfare.
“Gonna make you overload quick for me.” Sideswipe leans forward, hands braced to either side of Sunstreaker, hips thrusting in the pace he knows Sunstreaker likes best. His optics are bright and hungry, his glossa sweeping over and over his lips. “Wanna watch you whimper and writhe for me.”
Sunstreaker sucks in a heavy vent, his valve quivering. Sideswipe sinks into him fast and deep, with little circular grinds that put a delicious pressure on his outer node. More intoxicating is the wrap of his field, pulsing in tune to his thrusts.
Sunstreaker tries to rise up to meet him, but the cuffs limit his movement. All he can do is squirm, fluids making obscene noises between them, lubricant and transfluid both. Molten heat gathers in his valve, pushing him toward another overload, and a keen rises out of Sunstreaker’s intake.
He pants for ventilation, processor spinning. Sideswipe pushes into him, harder and faster, and then there’s a finger on Sunstreaker’s anterior node. It circles with a firm pressure, dragging all the fire straight to that sensitive sensor cluster. Sunstreaker’s weak to stimulation right there. Always has been.
He tosses his head back, grits his denta. Tries to hold on to his reserve, tries not to overload like some eager youngling recently discovering his array, but it’s impossible. Sideswipe’s field is like fire against his, and Sideswipe’s spike keeps jabbing all those nodes perfectly, and those circles are getting smaller and smaller around his node, until it’s just a hot-white flash of pleasure. A burst of it.
Sunstreaker drowns in his overload, making a noise that can only be described as binary as he shudders through a second overload, his valve spiraling down tight and milking Sideswipe’s spike for all it can give him. His thoughts drift in a haze of ecstasy, and it takes longer to find his frame again, as he sinks back into it, and the sensation of Sideswipe pushing into him faster and faster.
That droning noise is Sideswipe’s voice. His face is creased with delight, his optics hot and bright, lips moving.
“Fuck, you’re too sexy like this,” he’s blabbering, Sideswipe starts resorting to human swears when he gets too aroused. “So gorgeous and sweet. Love the way you feel around me. Love it when you overload like that. Love all of it. Love you.” He groans, thrusting faster and deeper, fingers tangling in the berth covers for leverage.
Sunstreaker’s head spins. All the compliments strike along his processor like little flicks to his anterior node. He clenches, engine revving, valve pulsing with renewed vigor. He’s not even the least bit exhausted, and the feeling of Sideswipe overloading, filling him with more transfluid is intoxicating. The sound Sideswipe makes is guttural and hungry, and he suddenly pulls out, a couple spurts of transfluid striping Sunstreaker’s array and landing hot-wet on his node.
Sunstreaker moans, his thighs trembling. “More,” he pleads, his vision hazy, processor spinning in the best kinds of ways.
“More’s coming,” Ratchet says, appearing between Sunstreaker’s thighs as Sideswipe shuffles away, his spike bobbing pressurized between his thighs, wet with transfluid and lubricant.
Sunstreaker wants to lick him so much right now. His mouth lubricates with the thought of it, Sideswipe sliding into him, so hot and thick, panting heavily, careful as he takes Sunstreaker’s mouth. The taste of his brother on his glossa, the sound of Sideswipe’s pleasure…
Sunstreaker moans, one that changes pitch into a whine as he feels the wet swipe of a glossa over his valve, and the careful touch of fingers on his rim, stroking the sensitive plating around it. He cycles his optics, tries to focus, sees Ratchet’s head between his thighs, and feels the gentle kiss against his anterior node.
Sunstreaker’s head drops back. His spinal strut arches, hips squirming where Ratchet cradles them, as his mouth drops a dozen little kisses over Sunstreaker’s swollen valve. His rim ripples, his interior calipers clutching on nothing, squeezing out trickles of mixed fluids.
The berth dips as Sideswipe hops up onto it, snuggling against Sunstreaker’s side, peppering his intake with kisses.
“You have some of the best ideas, bro,” he says, ex-venting hot and wet, his field eager and charged against Sunstreaker’s. “We’re gonna fill you up so much, you’ll be cleaning us out for weeks.”
Sideswipe’s hand slides down his frame, over his chassis and belly, across his groin, and then his fingers are on Sunstreaker’s sensor cluster, giving it a pinch. Sunstreaker growls and arches his hips, a spike sliding into him not soon after, Ratchet’s spike at that, bigger than Sideswipe’s, thicker.
Sunstreaker keens as the spike touches his nodes. Ratchet grabs his hips, tilts them a little, so the ridged crown of his spike can taste those nodes only grazed earlier. It sends a shock of fire through Sunstreaker’s valve.
“I brought you a gift, Sunstreaker,” Ratchet says, his voice and field like little drops of ecstasy to Sunstreaker’s processor. “Your brother’s got it now.”
“Gift?” Sunstreaker repeats, processor spinning too much to make sense of it.
Sideswipe’s hand vanishes from his node, and before Sunstreaker can protest, it returns. And it’s not alone. He’s got something attached to his finger, something that starts buzzing and vibrating on the sensitive plating surrounding Sunstreaker’s anterior cluster.
Oh. Oh, Primus.
Sunstreaker tilts his head back, optics squeezing shut, hips bucking, as overload tackles him like a Combaticon on the battlefield, a full frontal assault that leaves him dazed and shaking on the ground. His entire frame arches, charge lighting up his armor, dancing out from his protoform.
Sideswipe eases off with the vibrator, enough for Sunstreaker to catch a vent. He goes limp on the berth, completely surrendering to their touch, to Sideswipe kissing him – wet and hot and openmouthed – and Ratchet thrusting into him, steadier and faster and deeper, his hands smoothing up and over and around Sunstreaker’s legs.
“You love this, don’t you?” Sideswipe asks, his voice dark and sultry, like secret fantasies and the caverns under Cybertron and the taste of the finest high grade.
“He’s suited for it,” Ratchet says with lust in his tone, like a powerful engine turning over, a blaster rising to full charge. “Pleasure looks good on him.”
“It does. Almost wish everyone could see it, see how beautiful you are,” Sideswipe says against Sunstreaker’s audial. “We’d string you up in the common room, black ropes all around your frame, tied so you can’t move.”
“At our mercy is a good plan,” Ratchet agrees with a grunt. His thrusts deepen, ping something deep inside Sunstreaker that makes him whimper with pleasure.
His thoughts spin, caught up with their voices, the pleasure promised in their words.
“Everybody can watch as we make you overload again and again,” Sideswipe murmurs, his glossa tracing circles over Sunstreaker’s seams. “They’ll want to touch, but we won’t let them. They’ll beg us, and we’ll say no.”
“Because you’re ours,” Ratchet pants, grinding so deep, his spike throbbing, the thick head tapping over Sunstreaker’s ceiling node again and again. “And no one else can have you.”
Sunstreaker moans. The claim sounds fierce, genuine, and it rattles around inside his spark. Sideswipe loves him; Sideswipe is his twin. He doesn’t have a choice. But to want to keep him? To claim him? That’s something entirely free.
“Yes,” Sideswipe hisses, hips rolling, his spike rutting against Sunstreaker’s side. And then the vibrator is back, buzzing happily over Sunstreaker’s anterior node, and he arches again, frame caught by pleasure. “All ours.”
Sunstreaker jolts, overload pouring through him like an electric attack, setting his sensor net ablaze. He chokes out a sound as his fans roar, his valve spiraling down tight around Ratchet’s spike, his hands forming fists. The chains rattle as he thrashes, caught up in the ecstasy, with Sideswipe and Ratchet’s hands to guide him back down.
He’s panting as he collapses onto the berth, condensation slicking his frame. He barely notices that Ratchet has overloaded again, and now the fluids are trickling from his valve, soaking his aft. The room smells of interfacing and lubricant and transfluid. His valve aches for more, rim twitching as Ratchet withdraws, and Sideswipe replaces him.
Sunstreaker moans, head swinging toward Ratchet, the medic against his side now, his lips gentle as they catch Sunstreaker’s for a kiss. He tastes like something sweet and wonderful, and his hands are as clever as Sideswipe’s, gentle as he runs the vibrator over Sunstreaker’s most sensitive places, but on the lowest setting.
“We’re going to keep going,” Ratchet murmurs, a steamy promise against Sunstreaker’s audials. “Until our tanks run dry, and we’re spilling out of you.”
Sunstreaker whimpers, processor going bright with need, his worldview narrowing to this and only this.
It starts to blur together. Overload after overload, Ratchet and Sideswipe alternating, taking turns caressing him and spiking him, until Sunstreaker’s entire frame feels as though it’s one big, sensitive node. Until even the touch of their fingers on his knee or his belly makes him wail with need.
He’s never empty, he’s always full. He’s surrounded by them, claimed by them, taken again and again. The berth is soaked beneath his aft. His frame is on fire, blue charge licking out of his seams to light up the room. He tastes them both on his glossa and in the air, and he wishes he could vocalize how much he wants to lick them, suck them, swallow them.
The words ‘stop’ and ‘daffodil’ never cross his mind. Higher processing goes away, turned to mush. His thighs tremble, and his shoulders ache, and he’s floating on air. He’s loose and sloppy and taken so thoroughly, there’s no question who he belongs to.
Sideswipe. Ratchet. Both. Together.
Together, the key word, because somehow in the haze, they’ve unbound his legs. Someone’s crawled beneath him, behind him, cradling his frame. Sideswipe, he thinks, his arms around Sunstreaker’s chassis, his head tilted against Sunstreaker’s, his words a hot puff of compliments against Sunstreaker’s audial.
He slides up into Sunstreaker, path eased by the copious fluids, and Sunstreaker’s so open, he can only manage a light clench. But it’s okay, because Ratchet’s here, too, between Sunstreaker’s thighs, his hands gentle on Sunstreaker’s knees. Pushing them up and back, opening him up, making room for Ratchet to ease into his valve as well, a tight fit but a good one.
Sunstreaker moans, his head lolling back against Sideswipe’s shoulder, his spark heavy and swollen with affection. They move together, a stretch just shy of pain, but it’s better like this. Better to feel them both at once, Sideswipe behind and Ratchet in front, closing around him, holding him close.
He starts to shake, and it has nothing to do with fear, but everything to do with a rising tide of pleasure. It starts in his feet and works up his frame, rattling through his armor. It starts at his head and flows down, over his intake and shoulders and chassis and belly. It meets in his groin, collides, and tangles into a tighter and tighter knot.
“That’s it,” Sideswipe urges, his hand sliding down, over Sunstreaker’s belly, back to his node, all slippery and swollen, twice the size it should be. “Come on, Sunny. Overload for us, baby. Give us one more. I know you have it in you.”
Sunstreaker whimpers, exhausted and limp, barely able to roll onto their combined spikes, drowning in the ecstasy they offer. Ratchet’s lips press against the curve of his jaw, and Sunstreaker’s mouth opens, inviting him inside, the taste of his glossa so hot and wet and fleeting.
Ratchet nuzzles him, so sweet and encouraging. “You’re so beautiful, Sunstreaker,” he murmurs, and Sunstreaker’s spark flutters.
Sideswipe says it all the time, but he has to, because he’s Sunstreaker’s twin, and his brother, and he loves Sunstreaker. Oh, he believes it, too and Sunstreaker believes him when he says it, but coming from Ratchet, it’s something else entirely. It’s someone saying, I don’t already love you, but I find you beautiful anyway, and it makes Sunstreaker’s spark clench with exhilaration and fear.
“One more overload, Sunny,” Ratchet purrs, and Sunstreaker can’t even be angry for the loathed nickname, not with Ratchet pleading with him. Not with Ratchet’s mouth so hot against his jaw. “One more.”
“One more,” Sideswipe echoes, and they both shove deep, push into him at the same time, filling him to the brim and almost to capacity.
Sunstreaker’s valve convulses. It spirals tight before spilling charge in wave after wave, lighting up his internal nodes and licking over his lover’s spikes. Sunstreaker’s breath catches in his intake as he overloads. It strips away everything, his frame arrested by ecstasy and casting him adrift in a sea of it.
Sunstreaker whites out, his spark dancing. He floats outside his frame, every sensor lit with lightning, every line, every inch of his dermal net until he can’t feel anything but pleasure.
Everything goes wonderfully, deliciously blank, and he forgets there is ever a time he feels worthless, undesired, and unloved. Not when it’s here, so obvious, so very present around him.
By the time he sinks back into his frame and stops floating, the world around him is a different place. Figuratively speaking anyway. Unshuttering his optics takes monumental effort, and his visual feed is filled with gray static at first, until he reboots both it and his auditory feed.
He senses Ratchet and Sideswipe around him immediately. Their hands and lips on his frame, peppering him in gentle kisses and careful swipes of a damp meshcloth. The cuffs and chains are gone, leaving him free to move, not that he thinks he can. Every limb is languid, exhausted, and all he wants to do is lie here and soak it in.
His engine purrs, perfectly content, a sensation he hasn’t felt in a long while. Sunstreaker makes a happy noise and tries to snuggle into the frame nearest to him – a heck of a lot of red, Sideswipe he thinks.
“There you are,” Sideswipe murmurs affectionately, and scrubs his cheek over Sunstreaker’s. “We wondered when you’d come back to us.” There’s a hint of worry in his voice.
“Sorry,” Sunstreaker mumbles through static.
“I told him you were fine,” Ratchet says, exasperated. But his touch is gentle as he wipes down Sunstreaker’s inner thighs in short, efficient strokes. And he sounds relieved, too.
“Felt good,” Sunstreaker manages. He sighs with satisfaction. Ratchet’s so good at this, and the strokes of the cloth are soothing. He could easily fall back into recharge like this.
Until he feels the cloth slide further up, toward his very sticky array, lubricant and transfluid both seeping out of him. Sunstreaker tries to twist his hips away, the motion aborted because of his fatigue, and makes a protesting noise. His face heats with embarrassment.
Ratchet pauses and arches an orbital ridge at him. “You don’t want to be clean?”
“No… not yet,” Sunstreaker admits as he commands his panel to close, trapping their combined spill and his own lubricant inside him. It’ll be a mess to clean later but right now, it’s a reminder.
He curls half onto his side, trying to tuck his face against Sideswipe’s intake so neither of them can see his expression. He doesn’t want to be that clean. He wants… He wants them to be close to him, around him as much as they are inside him.
“Just…” Sunstreaker trails off, unsure how to express himself, and tries to curl into Sideswipe again, weak fingers making an aborted paw at Sideswipe’s armor.
“Hold you?” Sideswipe finishes for him. He curls an arm over Sunstreaker and tugs him closer, half on top of Sideswipe. “I can totally do that. I love when you’re all snuggly.”
“Feels good,” Sunstreaker murmurs and lets himself go limp, completely notched against his twin, close enough that he can feel and sense the beat of his twin’s spark. But his back is cold, and he knows he’s missing something. “Wait. Where’s–”
“Right here.” The berth dips behind Sunstreaker as Ratchet appears from wherever he’d gone – probably disposing of the mesh cloth for now. He slides up behind Sunstreaker, curling against Sunstreaker’s back, draping an arm over his midsection.
He’s squeezed between them, the heat of their frames buzzing against his, their fields embracing him entirely. His processor still floats in that wonderful haze of pleasure, and his spark is a content twirl inside his chassis. His array is deliciously sated, and when he twitches, he can still feel the spike cap.
Eh. They can get it in the morning. Sunstreaker doesn’t want to move. He likes this just the way it is. His twin and their lover petting him, two pairs of hands stroking over his frame soothing and adoring.
He never knew there could be this much bliss in a single moment.
“Told you we’d do it,” Sideswipe murmurs into the peaceful quiet, because he can never abide by silence for long, the brat.
“Shut up,” Sunstreaker grumbles. Always has to throw in an ‘I told you so’.
Ratchet laughs, the sound of it vibrating between Sunstreaker’s shoulders. “Anything for you, Sunny,” he says as he strokes his palm down Sunstreaker’s side, his field adding warm and comfortable pulses.
For once, Sunstreaker actually believes they mean it. Maybe he’s not ready to divulge all the other secret desires just yet, but he thinks he might in the future. Someday.
He’s getting closer to it any rate.
Because they love him. He’s sure of it. All that’s left is to trust it.
