Chapter Text
Optimus stares at the blank spot on his shoulder in the mirror, and feels... oddly bare to the universe. He's covered in a frilly dress, long gloves, and thigh high stockings, but he feels naked.
Megatron walks behind him, kissing his neck, "Optimus, my beautiful Beloved."
Anything would be better than this bare spot of armor, so he looks up at Megatron, catching his gaze through the mirror's reflection. "Will you put your mark on me?"
Megatron's servos spasm against his armor. "My . . . you want the Decepticon insignia?"
Optimus nods slowly, and reaches up, catching one of Megatron's servos in his. "I want that, but I want your mark on me more. I know you have bonding paint ready." He wants to just ask Megatron to frag him, but he will not risk bringing a sparkling into this world without a bondmark on his servo.
"... Do you mean it?" Megatron looks and sounds hesitant, like he expects a refusal.
"I do. I want to be bonded. I want to bond to you. I can't imagine not bonding to you." He looks at the mech in the optics, "I want to spend the rest of our lives together, having as many sparklings as we can."
Optimus laughs softly as Megatron's hips jerk against him, "I'll paint you now."
"Do you have the paint with you?" Optimus teases, because he's learned that Megatron can be quite impulsive at times. Not that there's something inherently wrong with that, of course.
"I have had a bonding brush and paint in my subspace since the sol I got your designation from you," Megatron growls in his audio, and that makes Optimus shiver in pleasure, pressing back against him.
"Then take me to the altar and paint me, my love," Optimus pleads, wanting it more than ever now.
Megatron bites his neck, "The altar?"
"I want to have our first time to have the certainty of a sparkling."
"Through the Rite Of Primus we'll be bonded. Is that what you want or to be painted?"
"Paint me."
Megatron pulls out a bonding brush, which is a work of art, saying, "Then I must paint you here first. I don't want Primus to push me to interface before you're painted. I can feel Primus's energy, even through the wall, guided through the altar. I love you so much."
He moves so they're face to face, and kisses Megatron happily, "Then paint me."
Megatron's glossa tangles with his for a long klik, and then the mech pulls back, dipping his brush in a pot of shimmering golden paint. "Will you be mine, from now unto Eternity?" he asks, suddenly formal.
Optimus holds out his servo, the one marked with an Oathbond. "I will be yours, if you will be mine." The paint burns down to his protoform as Megatron strokes slowly and deliberately over his servo, tracing patterns that twin together with the Oath mark. His bond mark looks like something from an elaborate ceremony, and Optimus feels a moment of shame knowing that he won't be able to manage anything as beautiful for Megatron.
He takes the brush, and Megatron can see his hesitance. "Beloved, you could put a splotch of paint all over my servo, and I'd treasure it. Put how I belong to you. Anything you want. You could paint my servo, and then write on my aft how I'm your property."
He looks at his mech with narrowed optics, "Maybe I should paint a collar on you."
"If that's what you want, then do it. Even if you know that we can go out and buy one once we're done celebrating."
He snorts, "Yes, but I think..." He takes Megatron's servo in his own, "You said you wanted a sparkbond?"
"Oh... Of course! Do you want to do it this sol, or-"
"I just... I want to mark that we will have one, even if it isn't right now. A double band for you, and we will sparkbond later. Not tonight."
So Optimus carefully dips the brush into the etching paint and does his best to keep his servo from shaking as he paints a simple set of bands around Megatron's fingers, adding one decorative loop when he thinks he can manage it. It ends up just a little shaky at the end, which he counts as a victory. When the brush and paint are tucked away, Megaron takes his servos and holds them tightly. "My bondmate."
Optimus smiles at him and rests his cheek against their joined servos. "My bondmate. Take me to the altar."
Megatron wraps his arms around him, holding him with care, "Are you wearing anything you don't want damaged?"
"No, I'm.." He hums, "Ah, I know what I should do first."
"Yes?"
He pulls away, and reaches into his subspace, pulling out a pair of panties. Ignoring how Megatron revs, he reaches under his skirts, and carefully disconnects his valve plating, putting the panties on as well. Putting his plating in his subspace, he says, "I'm ready now." Looking his mech in the optics, "You will break my seals with your glossa. Not your spike."
"As you wish, Beloved," Megatron hums, and carries him to the altar, stopping in front of it to put him down. Optimus is about to ask what the mech is doing when he sees Megatron spread several meshes down over the surface. "There, more comfortable." Then he's lifted and laid out on the altar like an offering. Optimus shifts on the meshes, feeling a little embarrassed by that thought. If he's an offering, he's not something Primus will find very pleasing. So he makes promises to himself to offer better fuel and a full Litany of Primus after he is sparked as a thanks for his God.
Megatron crawls up onto the altar over him, optics hot, and Optimus reaches up to pull him down for a kiss. Megatron doesn't argue, just kissing him back happily. When Optimus pulls away, his mech presses kisses down his frame, pausing in clear shock as Optimus opens his back panels to reveal his spark. At his mech's look, he says, "We will go spark to spark, so you are more than allowed."
"Do you want me to lick-"
"No," he says firmly. "You have been told what you're doing first, and you will do it."
Megatron chuckles and continues kissing down his frame, growling a little as he gets to his interfacing array. "Beautiful." The mech rips the panties off of him, and Optimus is glad he chose a boring pair of them. "And mine." Megatron traces around his array with his fingers, and then leans in, letting his glossa flick over Optimus's node. Optimus squeaks in shock at how good it feels, hips bucking up against him. "So lovely," Megatron praises, and then sucks his node, and Optimus's thighs clench around his helm, trying to hold him in place while the mech pleasures him.
He whines when Megatron shifts away from his node and then shrieks as something pierces through his valve seal--but the tiny shock of pain is gone as quick as it came, while Megatron's fingers rub tight circles over his node.
He can feel Megatron's glossa pressing into him, and he mewls softly, hips rolling at how pleasurable it is. Not at all like the hacks to make him feel like a spike in him, but very good. His mech's optics are bright with lust as Optimus finds what focus he has to look. It's clear how much Megatron is enjoying this. He mewls in pleasure as Megatron pinches his node, and he reaches down, playing with his mech's helm.
"Love you," he pants out.
Megatron smirks at him and shares an internal com, ‘I love you too, Beloved.’ Then he shifts, glossa flicking over his node for a moment, before he feels that mouth press over his spike seal, glossa teasing him there until his spike pressurizes up and out, and Megatron starts bobbing his helm over his spike, glossa curling around it, while his fingers pump in and out of his valve.
Optimus arches his back and overloads with a cry, frame shaking with pleasure, and Megatron doesn't let off of him until he's slumped back down, quivering with aftershocks.
His mech slides above him, kissing him possessively, and rubbing his frame, "Beautiful. Always so beautiful."
Optimus reaches between them, his servos confirming what he can feel pressing against him is his mech's spike. he spreads his legs in a tired invitation, his clear chestplate retracting entirely to expose his spark. "Husband, you need to spark me up now."
Megatron shudders, almost looking like he'll fall on top of him, but Optimus lets go so that Megatron can slide his spike right where it belongs. Megatron groans, pressing into him entirely, easy due to how slick he is from both the bot's glossa and the overload. "I suppose it is only fair you finally see my spark in person, rather than just pictures."
When Megatron opens up, he reaches in with his fingers, touching it lightly, "Spark me."
He is not ready for the power of Megatron's spark, which presses against him so completely, so fully that he can't feel anything else. Optimus clings to Megatron as the mech rubs their sparks together, energy crackling wildly between them, his valve spread deep inside by the mech's spike, and he cries out in overload, losing himself to darkness.
--
Optimus onlines, feeling full and satisfied in ways he's never felt before. He shifts and finds that they've moved to a proper berth, and he's nestled against Megatron's side, tucked under several meshes that have him feeling warm and toasty. He snuggles closer and practically purrs as Megatron's servo strokes his frame gently.
"You know, I had not expected you to trigger sparkbonding protocols on our first spark interface, sweetspark," Megatron teases him.
He frowns, "I didn't." He knows he didn't. In fact, they should still be locked off. ... But a check of his processor says that he is sparkbonded.
Megatron hums, frowning, then looks to where the altar would be, if there wasn't a wall between them. "We probably shouldn't have had our first interface on an altar. I've heard of Primus forcibly sparkbonding his favoreds together, but I was expecting that not to happen to us."
"... he does?"
"He does."
He looks at his chest, touching it, and seeing about if he's sparked. He can't actually tell. But there is a glowing blue mark on his servo, and it isn't the oath mark, this one is around his wrist and winds up his fingers, looking surprisingly pretty with the mark Megatron painted. "And this means?"
Megatron looks smug. "Rite of Primus, and clearly we're favored by Primus, since it's not just a small bit of blue somewhere on the servo. Bots will know that you're sparked, and we are bonded. Even if we hadn't painted."
Optimus sighs, "Well, I did want a sparkbond with you eventually." If Primus willed it to be so, that meant it was right. Nothing can break a sparkbond. Even after they offline, they will find each other in the Well, and it is said that if one of them reincarnates, the other will follow and they will find each other again. "I wonder what kind of mech we've sparked."
Megatron kisses him deeply, rubbing his helmfins in a very distracting way, and Optimus squirms, feeling his valve ache with want. That's going to be very distracting now. His mech says softly, "Do you want to get scanned now, or should we wait? If we wait, we'll have a better idea of what we're blessed with." Megatron pauses, looking at him, "And we just got bonded. Do you want to ruin that with seeing Hook's ugly faceplates?"
He rolls his optics, "Let's get scanned."
"Very well." Megatron sits up, "I think we should put some new clothing on you, since your panties are ruined, and I want you to be in something nice, since I can finally show everyone how wonderful you are."
"You just want me in that frilly monstrosity I refused to put on the other sol." It made him look like a frosted crystal cake with so many layers of skirt that he feared he would get lost in them.
"You caught me," Megatron chuckles, and then drags out the mess of lace and petticoats. Optimus lets himself be dressed without too much of a fuss over it, though he draws the line at the corseting armor meant to go under the top.
"I won't have anything squeezing on my sparkplates anytime that I'm sparked."
Megatron looks at him, then puts it away, "That is a very good point, Optimus. We can do it when you aren't sparked."
"When the medic says we're taking a break from sparking."
Megatron nods, "You mentioned you want to do resparking?"
"I do."
"Then when we're told we can't respark, we'll do it." Megatron kisses him, "Now, the pedcovers."
He scowls, "... Fine, but only because you're carrying me." He hates them, but as long as he doesn't need to walk in them, he'll accept it.
The pedcovers are horrible as usual, but he does admit that they look nice. He looks nice, decked out like this, even if this sort of dress would be useless around their rooms. The skirts are too poofy, and the long, trailing sleeves look pretty draped down while Megatron carries him, but they would just get in the way trying to do anything. Optimus settles against Megatron's chest and relaxes. "I'm hungry."
That results in a cube of rich whipped fuel and a few crystals to munch on while Megatron carries him out of the room.
He happily eats it as Megatron clearly carries him down an open and wide hallway. Optimus blinks as various bots murmur things as they walk along the very busy hall. A glance at his husband's smug expression has him rolling his optics, but he knows what the bot wants him to do. He very deliberately starts waving at bots with his painted and blessed servo, and keeps fueling with his other.
It gets louder murmuring, clear excitement frizzling through the bots. One is bold and whistles at them. A glance around doesn't really reveal who does it, but Megatron just looks amused rather than annoyed.
Optimus gets the feeling that if it wasn't him with Megatron, there would be some yelling and congratulations going on.
It only takes a klik to remember that Decepticons are rather more . . . open about their interfacing habits, as he's carried along, seeing as there are four couples interfacing up against the walls. Megatron doesn't seem surprised at all, simply passing by them without comment.
Optimus isn't sure he'll ever be willing to interface in public like that, but he's not sure that he won't either.
He doesn't have to worry about it as they go into the medbay, and Megatron sets him carefully down on an exam berth.
Hook comes over almost instantly, looking pleased, "My lords!"
Megatron looks smug, "Hook. Optimus needs a scan. We'd like to know about our sparkling."
Optimus looks at his arms, "Uh, I don't know how to open a port with this on."
Hook chuckles as Megatron moves the sleeve so he can open a panel, his husband kisses him softly, "There."
Hook connects up, running a scan, and saying, "Should I do more than just the sparkling?"
Optimus is about to refuse, but Megatron says, "Yes. I'm certain that if there was damage, Primus repaired it, but be sure nothing is damaged in his interfacing equipment. I don't want him to possibly have a rip in his valve, or something breaking and hurting him."
"Or lacerating your spike and damaging him even more as it happens," Hook agrees, and the scan intensifies.
Optimus sighs, sure that he's fine. All he feels is a mild ache, and that's surely normally the sol after taking a spike as massive as Megatron's is. Still, he suffers through the process silently, willing to indulge in Megatron's overprotectiveness.
"No damage, my Lords," Hook reports, disconnecting the pads. "And allow me to be the first to congratulate you on your triplets. They look to be truckbots, and their coding is tending towards femme code already."
"... femmes?" Optimus asks, uncertain.
"I believe so, that's what it looks like."
Megatron laughs happily, picking him up and spinning him before throwing him in the air to catch him, "Triplets! Femmes! We're truly blessed, by Beloved!"
Optimus catches his bearings, and then kisses Megatron happily, "We'll be certain before we say femmes to the public, but we can announce triplet truckbots." Since he knows from how excited his mech is, Megatron won't want to keep this silent.
Well, he can certainly accept Primus binding their sparks together if it meant that they had triplets as a reward. Optimus rests a servo over his own chestplates, trying to send his love to his new sparklets. No matter what they were--mech, femme, or those rare few who were somewhere in between--he would love them with all of his spark.
"Oh, I will announce it to the Universe, as I announce our bonding as well, Beloved," Megatron promises with a grin. "We are blessed."
