“What, you don’t think I did my research?” Sentinel crosses his arms over his chassis.
“Well, Sentinel, it’s you-”
“C’mon, it’ll be one night! The planet has hot springs and practically no organic life on it- It’s just harmless, gross plants, that’s the good part!”
“Optimus, I’m sure that it wouldn’t be that bad if we went.” you rest your servo on his shoulder, stepping closer to the bots. “It’s a good chance to relax.”
“Alright, fine. If we get in trouble it’s Sentinel’s fault then.”
“I’ll take that chance!” Sentinel rushes off to gather some overnight essentials.
“We should pack too, Optimus.” you kiss the side of his faceplates, walking off to join Sentinel.
Sneaking out of the academy would be the hardest part. The three of you wait til curfew, sneaking out with ease in between the security shifts.
Getting a rental ship was even easier. You were quiet in the academy, so usually Sentinel and Optimus would stay back until you rented the vehicle. This one was a crappy two seater, so Optimus would have to sit on your lap.
No big deal, you think, until Sentinel’s piloting skills are brought into the equation. It’s a bumpy ride and Optimus’ aft was rubbing against your should’ve-been spike paneling, if you were created with one, it would’ve been inside the red bot already.
But you don’t have a spike, your mind jarringly reminds you, knocking yourself away from those good thoughts. Your mind begins to wallow into the sad, spark sinking feelings. A dramatic change in altitude makes Optimus yelp.
“Hold on to your afts!” Sentinel laughs, Optimus’ servos fly to your thighs in an effort to keep upright. Sentinel brings the ship recklessly closer to the ground, landing with a couple bumps before completely stopping.
The blue bot jumps out of the ship to explore with a celebratory ‘woo’, Optimus, even though you can’t see his faceplates, he looks rattled beyond comprehension.
“Oppy?” you gently rub his side. “You alright, babe?”
“I am not relaxed.” Optimus shakily growls, relaxing his servos from the steel grip he had on your legs. “I’m driving on the way back.”
“Hey! Am I exploring alone or not?” Sentinel yells. Optimus sighs, getting off of your lap and out of the ship. You hop out, gazing out onto the new planet. It’s sunset, you think, and there are three moons that decorate the sky. There are trees in a far away place, and you can hear liquid bubbling. Weird.
“Ooh! Found one!” Sentinel’s voice comes from somewhere off in the distance.
“Sentinel where are you?” Optimus yells angrily, waving his servos up in the air. Sentinel peeks out from behind a relatively young tree with a big smile.
“C’mon!” he ushers, so you walk that way. Soon enough, all three of you are standing at the edge of a steaming pool of clear liquid.
“Is it safe to go in?” Optimus worries, Sentinel brushes him off with a wave.
“Of course it is! I did my research, remember?” he laughs, sticking a pede in the water to test the temperature. Without warning, he jumps in, managing to completely cover you and Optimus with the splash. The flooring of the odd pool made it so that Sentinel didn’t hurt himself jumping in.
“Y/n,” the blue bot says in a sing song voice, swimming up to the pool wall. He hooks a digit on your stabilizer vents as Optimus lowers himself into the water. “come in with us.”
“I dunno, it looks-” you’re cut off by Sentinel lunging out of the water and pulling you in, pulling you on top of him. He kisses your faceplates, laughing. You smile, kissing him back. “Dammit Sentinel.”
“Oppy, get your lonely aft over here.” Sentinel smiles at him, he’s still wading into the water. He grabs the red bot’s servo, pulling him down on top of both of you. You giggle, hugging onto them.
Optimus tries to sit upright, but falls backwards, back into the water because of the weird slippery flooring. You and Sentinel laugh, you try to sit him upright and Optimus sighs, glad to finally be vertical again.
“So… I was thinkin’ that we could try something.” Sentinel smirks, quickly adding, “If you both are up to it, of course.”
“What kind of trouble did you find, Sentinel?” it’s more of a statement than a question from Optimus.
“When the liquid is exposed to cybertronian mesh, it acts as an aphrodisiac. So if you open your panels and relax, you’ll be charged up way faster.”
“I’m fine with that, Y/n?” Optimus reaches for your servo, you clench your servos, pulling them closer to your core.
“Oh- um. Interfacing? Sure! Yes.” you’ll just have to explain why you don’t have the same ‘equipment’ as they do. Not as easy as it sounds though, every stupid time you reveal that little part about yourself you begin to cry.
“Hey if you don’t want to, we can go back home.” All you have to do is not cry.
“No, I want to. I’m just worried, I don’t want any of us to be sparked.” that’s believable.
“Who said anything about spiking?” thank Primus. The water seemed just opaque enough to conceal your secret, you try to convince yourself. “But, seriously, if you don’t want to, we shouldn’t.”
“I want to.” you lean in to kiss Sentinel, trying to further convince him. And yourself. You do want to, there’s no one else who you’d rather experience this with, you just wish so badly that you could experience this in a different way. The not-wrong feeling way.
Sentinel’s servo travels up your stabilizer, more and more dread fills your chassis the higher he goes. Higher and higher until your knee strut jerks up, throwing his servo away from your panels.
“Sorry! I’m sorry!” you cry, coolant already streaming down your faceplates. “Frag I’m sorry, I’m so sorry Sentinel.”
“Y/n it’s alright,” Sentinel throws his servos up, showing that he’s not going to touch you anymore.
“Are you okay?”
“Is it the… issue we talked about when we started dating?” Optimus asks, gently resting his servo on your shoulder. You nod and sniffle. “Do you want me to tell Sentinel for you?”
This time you shake your head no. He needs to know this and he needs to hear it from you.
“Whatever it is, tell me when you’re ready.”
You try and calm yourself down, blinking away the spilt tears and gaining control over the quiver of your bottom derma.
Sentinel seems to shrink, his shoulders slump and he hunches a but. His mind flips through all the possibilities, worried that he’d triggered a horrible memory or created one for you. Did you actually want to interface? Are you disgusted by Sentin-
“I don’t have a spike.” you snap Sentinel out of the thoughts. “I was forged a femme without a spike and the medics at the academy tell me it’s a cosmetic thing, so not something that they’ll deal with.” you sniff again, this time wiping a tear off of your faceplates. “I’m sorry for not telling you sooner.”
“Y/n,” a gentle servo cups the side of your helm. It doesn’t force you to look up at him, but you do so anyways. His other servo is entwined with the red bot’s. “I love you n’ Optimus more then anything in the universe. And there is nothing that’s gonna stop me from loving either of you.”
You give him a weak smile, tilting your helm into his servo. You shift your frame to wrap your arms around his neck cables. “Thank you, Sentinel. Optimus, c’mere. You’re part of this too.” Optimus chuckles, wrapping an arm around you and the other around Sentinel.
“Do you two still want to, or did I screw the mood completely?” you blush, awkwardly smiling.
“We still want to.” Optimus says, rubbing your back strut.
“Okay, good.” you sigh, bringing a servo closer to your interface panel. You lean over Sentinel’s chassis to give Optimus a kiss. Sentinel’s servo grazes along your stabilizer again, this time without the dread, while he kisses the other bot. His servo doesn’t shy away. Despite being solely attracted to mechs, despite your frame not matching up with his needs, he isn’t disgusted. And neither is Optimus. You smile, running a servo down Optimus’s chassis and squeezing the blue bot’s thigh, digging your digits into the plating seams. Sentinel whines and the red bot chuckles pulling away from the kiss.
“So good for us.” Optimus says, teasing you, tilting your chin up with a gentle digit.
“Oh no, don’t do that,” you blush and hide your faceplates with both servos, not meaning it.
“Do what?” he plays dumb, smiling and locking digits with you.
“T- that thing! With- with the-”
“Oh, you can take it.” Sentinel rubs your thigh, giving you a devilish grin. Optimus must have commed him and clued him in on what he should say.
“I know you can,” Optimus privately comms you, /Is this still okay?/ You quickly respond with a yes, the red bot smiles a bit more. “You’re gonna be such a good bot for us, right Y/n?” you whimper at the praise, blushing and squirming where you sit. “Open your panel up for us, hm?” you do exactly that, your own digits on your exterior node right away. “Oh what a good bot.”
It’s Optimus’ turn to blush as you reach for his spike, leaning over to kiss the blue bot. Sentinel’s servo bumps yours, hooking on your digits to pull it away from your array. You clumsily grope around Sentinel’s hips, making him whine again and reach for your array. Arousal grows hotter and hotter in your core, making you squirm where you sit, blushing. Sentinel kisses the red bot as soon as you pull away, making his faceplates warm up. You chuckle at the blue bot’s shyness, he looks almost starstruck when Sentinel pulls away from him.
“Good bot…” Sentinel chimes, smiling and kissing you. You rub the tip of Optimus’ spike, making him shake and moan. You hum, pulling yourself back before your ventilation system could start straining. You notice Sentinel’s servo on Optimus’ array, the red bot whines and squirms as you trail your digits down to his valve. You smile giddily, bringing Optimus into another kiss when he tenses, whining and shaking. His back strut arches and overloading into Sentinel’s servo with a dark blush on his faceplates. The red bot gasps against your derma, letting his frame slowly relax.
“So handsome,” the blue bot leans in to kiss Optimus once again. Optimus hums, eventually pulling away from the other and resting his helm on your shoulder, turning his attention and servos to you. His servo gently rub at your array, he kisses at your collar guard while putting an arm around your waist.
“Optimus…” you sigh, touching his thigh with one servo and stroking Sentinel’s spike gently. The blue bot groans, scooting closer to you and kissing you, a servo on your faceplates and the other on your array, bumping into Optimus’. You shudder at the feeling, unconsciously squeezing Sentinel’s spike and making him tremble, too.
“Y/n,” Optimus mimics your tone, venting against your neck cables. It makes you tremble and groan, bucking your hips up into their servos. The blue bot moans, licking your derma and pushing his spike into your servo. Sentinel gasps, erratically thrusting and shaking in his place on his knee struts, halfway over your frame. He finishes with oral lubricant dripping down his chin. You lick some of the lubricant off of his face, sliding your glossa over his faceplates and to just below his optic. When you pull away, Optimus is staring with blush still on his faceplates, pressing on your outer node and making pleasure curl in your tanks. The red bot mumbles a quiet, “Primus, that’s hot.”
You let out a half whine, half laugh and grind up into their servos. Sentinel puts his helm on your shoulder, licking his dermas and kissing at your collar guard. More insistent touches to your valve mesh make you overload, clenching your jaw and squeezing Optimus’ thigh, making him whine, too. You gasp and shake, coming down from your high with kisses on the edge of your faceplates and gentle touches to your midsection.
“So,” Optimus says quietly, smiling and rubbing your side carefully, “do we want to go back?”
“We should stay here, just for a bit longer…”
