Synopsis: After the bots found out that our genitalia was compatible things got kinda awkward with you being the adult usually on base. Although Optimus has been acting the strangest, you should talk to him.
Little did you know things would go from a 2 to a 10 incredibly fast. Talk about fast burn.
Who could have known that Miko saying âSuck my dickâ at a Decepticon would lead to you having to explain the birds and the bees to the bots when the kids left. Only to find out that they too had sexâŠwell interfacing.Â
Being that you were an adult and you didnât trust the kids to properly explain you did, but this situation came with its problems.Â
Things have been a bit more awkward with you and the others but especially Optimus. He barely talks to you and whenever he does he avoids eye contact and puts his mask up.Â
Well, youâve just about had it. You missed your talks with Optimus about the books you read and the books he likes. You missed the casual and insightful discussions. You are going to get to the bottom of this if it kills you.Â
You get up from the couch and start to walk deeper into the silo to Optimusâs room. Ratchet looks over and raises his eyebrows before speaking in his gruff tone.Â
âYou usually head home around this time where are you going?â
You turned and pouted, âIâm sick of Optimus avoiding me. Communication is healthy so Iâm going to communicate that I want answers.â
You saw him open his mouth to say something before changing his mind and waving his hand.Â
âNot my problem anymore, I donât want a part of it.âÂ
You raised an eyebrow in confusion before shaking your head and running to Optimusâs room. You didnât bother knocking and tried to open the door.Â
Odd, it wasnât opening. Luckily you remember a trick Miko taught you that opens any door in the base. She saw one of the hots put in the same code to doors that supposedly needed a different code. You put in the code and took a step back as the door opened.Â
You noticed how the room was dark, you couldnât see if Optimus was in there. You took in a deep breath before you realized, âI canât see him so if I call out asking if heâs here and he doesnât answer then Iâll just leave even if heâs here.âÂ
So you strutted into his room, âOptimus, we need to talk. Now.âÂ
You saw the dark figure of Optimus come out from the shadows. He was holding a data pad with both hands as he walked to you. For a mighty prime and leader, he looked nervously at you. His voice was quiet and shaky but still held the weight of its speaker, âY-yes, ahem. Yes Y/n is the the ma-matter of great importance?âÂ
âLook I since that uh âtalkâ yeah letâs call it that youâve been, I donât know distant? Like whatever happened to our book talks or our little chats now and then.âÂ
As you talked Optimus remained silent. Shifting from ped to ped.Â
âNow I know that we are technically partners and good partners talk to one another about problems and this awkwardness between us is a problem and-âŠ.â You took a second to look at Optimus, his finials were pinned back, he almost looked like he was panting, you could now hear the low thrum of cooling fans, and looking at his hands holding the data pad you could see they were trembling slightly. There was also a slightly blue tint to his cheeks. You made a confused face and asked, âAre you okay?âÂ
Optimus took a deep breath and nodded, âI am, youâŠâ he swallowed thickly and shook his head before looking at you again âyou may continue.âÂ
âAs I was saying, this awkwardness between us is a problem so like all problems we need to talk about it instead of just avoiding it so-âÂ
You looked up around at the sound of something dripping.Â
You look around again and see something pink on the floor in between Optimusâs legs, and as you looked at the spot in confusion you saw something pink drop onto that spot on the floor. You craned your neck up to look at a visibly very nervous Optimus. Your eyes landed on the data pad covering his crotch.Â
âOptimusâŠwhy are you covering your crotch?âÂ
Optimus avoided looking at you in the eyes, âI am simply holding the literature I was reading tonight, it does not matter how I-!â
While he was talking you walked close enough to Optimus to seeâŠthat a panel in between his legs was leaking a pink fluid.Â
ââŠSoâŠdid you wet yourself or are you just happy to see me?â You said completely panicked on the inside. âLook, Iâm sorry I can-âÂ
âPlease forgive me Y/n I canât apologize enough for my actions. Ever since the knowledge that you and I are biologically compatible in that way, my mind has not strayed from the thought of you. From the thought of us interfacing.â
You stood there, in his room, face blank trying to process what he just said. âI uhhh,â you didnât know how on earth to react, âI was just saying that to ease the tension. You could have given me any other explanation and I would have believed it. IsâŠthis why youâve been avoiding me?â you questioned despite practically knowing the answer.
Optimus's eyes widened in shock. He just told his crush that he wanted to frag her when he could have avoided it entirely. He closed his eyes and hung his head in shame, humiliation, and embarrassment. Tears formed in the corners of his eyes.Â
âF-forgive me. I should have better reign of m-my emotions. As a leader, as a prime.â
âWait wait, so youâŠwant to fuc-âŠinterface with me? Why didnât you just, I donât know. Say you were interested in experimenting?â
âBecause you are not an experiment.â Optimus said firmly, finials up and face serious. âYou are a kind and loving spark. I could never take advantage of a being like you when m-my feelings for you are more than that.â
âyou like like me.â
âI apologize for my behavior.â
You made your way to the door and you could practically hear Optimusâs heartbreak. You put in the all-purpose lock code mentally thanking Miko before turning around to see a very confused bot. You let a smirk cross your face.Â
âWelp, I guess this just became a fast burn.â You slowly made your way back to him, arms behind your back and a devilish grin on your face. âBecause I like like you too Optimus.â
His eyes widened at your statement he looked hopeful, he knew that perhaps he had a chance with you. âYou do? But you did not know until recently that I couldâŠfulfillâŠyou through interface. You still had an attraction to me?â
âBefore I answer then am I right to assume that you loved me too before that talk?â
He nodded his head firmly.Â
âThen you also were willing to love me even though I would not be able to fulfill those desires. Should you not expect the same unconditional love for yourself?âÂ
You sighed as he looked away in self-consciousness and embarrassment, his face flushed with the blue hue of Energon. You glanced down and saw the puddle of what you assumed to be some kind of pre-fluid and saw how much bigger it had gotten.Â
You walked up to his metal bed and stripped off your bottoms throwing them on the floor. âSo, youâve been craving me yeah?âÂ
Optimusâs jaw dropped and his cheeks turned three shades darker. He had to check if this was a recharge flux. His human, his favorite human, the one he had spent many nights crying out her name, was on his berth ready to give herself to him. He had to decline the request to open both of his panels.Â
âLetâs play a game, what makes you want all of this, the most.â You say gesturing over your body.Â
âIs it the fact that such a little thing can possibly take you?â
Optimus bit his derma. You crossed off size kink.Â
âIs it because you want to see me overflowing with your cum?â
He gasped and groaned. You felt like you were getting close. You remember how he specifically mentioned how he knew you were âbiologically compatibleâ and that stirred things upâŠyou canât help but wonderâŠ
âIs itâŠperhapsâŠyou wanna put a baby in me?â
He let out a gasping moan. He dropped the data pad just in time for you to see his spike emerge and harden and his valve panel open to reveal his puffy lips and glowing clit- no, his anterior node.Â
âWould you look at that. I won. You wanna pump me so full that thereâs no way I wonât carry your chi-sparklings?âÂ
You watched in glee as Optimus whimpered and nodded. âI h-have always respected life and itâs beauty. T-the matrix amplifies the w-want to create life. Knowing that you could foster life, i-itâs made me it h-hasâŠhas.â he choked out a needy moan.
You leaned back and opened your legs, âAs much as I love the look on your face, do you wanna continue? Because if you are not ready I will put my pants on and lea-âÂ
A dark shadow consumed you, you looked up to see a slightly smaller Optimus. His hands were planted onto his bed on both sides of you caging you. He must have seen the confusion on your face because he explained his size change, "I am using mass displacement, you would not be able to take me otherwise." He no longer could hold you in his palm but you were certain that you now barely came up to his waist he was still very big, as well as his spike.
You saw how it was twitching and leaking and hummed. "By the looks of it your nice and ready but I think I'll need a little prep before I can take that third leg of yoOOUUUrrrRRSS! mmmgghh!" Optimus took the liberty to start going down on your entrance, his tongue sent jolts of pleasure up your spine and out your mouth in a low moan.Â
"Y-you don't have to do this I'd be fine if you just fingered me."
"No, I n-need to taste you, before I spill into you." he said licking a long stripe over your entire womanhood.
You let out a pleased moan, "You w-wanna ahhmm make sure I'm all prepped to be bred? That I'm able to take you s-so nicely that I can take your, uhh, trans-fluid yeah?" That was the right thing to say because you could feel Optimus's tongue plunge into you. You cried out in pleasure as your first of many climaxes hit. It left you gasping for air. He then started to give your throbbing clit some attention while one of his big fingers began to finger and stretch you, hitting nerves you didn't know existed.Â
"O-oh yessss, mmm, so very v-very well. You better hurry though. The quicker I can take you the quicker I'll feel you fill me up with your cum." He stalled and whimpered, by the looks of it your dirty talk was making him overcome with arousal. He couldn't think straight, the teasing, the praise, he had to try and stop himself from overloading right then and there.Â
'I can't' he thought as he increased the speed and number of his fingers into your warm plush valve, 'I have to overload in her, I have to fill her and spark her up with my trans-fluid. A human, my human, all swollen and sparked up...by me.' At those thoughts, he winced as his spike got so hard it was getting painful, his charge was high and he was still untouched by your hands.Â
You became aware of his plight and spoke, "I uff I think that's enough now, it looks like it's starting to hurt for you."Â
Optimus nodded backing up and sitting up, coolant coating his chest and face. You could see steam coming off him and thick smoke coming from both of his tailpipes. "You are so beautiful, in spark and in mind. Your words are...v-very arousing."Â
Your grin was like the Chesire cat, "Really? Come here and show me how well I'm doing." As if you had him on a leash he crawled towards you, he encased your hips with his hands, "You will tell me if this becomes to much, I never wish to harm you Y/n," Your gaze turned soft and loving, you put one of your hands on his and motioned for him to lean closer, he did. You could feel the heat radiate from him and could smell ozone in the air as well as something sweet. You put a hand on his cheek and spoke in a low tone, "I know, I trust you. Now...breed me, make me yours, fill me up so much everyone knows I've been claimed and belong to you~."Â
He nodded dumbly and carefully lined up his spike with your hips, he slowly pushed in and bottomed out with a grunt. He let out a desperate pleasured cry, "Aaannnggh!" He bent over you caging you as he began to rut into you. "O-oh yes, yes. Knock me up, make it undeniably that I'm pregnant."
Your words spurred him on making his thrusts erratic and desperate so you continued, "Oh you like that huh? Your doing so well, filling m-me up s-s-sooo goood." You mewled out a soft moan overcome with pleasure. "You wanna fill me up m-ma make me feel so good?" He nodded and tears from the pleasure welled in his eyes. "F-fill up...make you f-fe-feel gooood" his gasps and moans were strangled, utterly consumed by you. "Sparl-sparked-ed a-all full a-a-and mi-i-i-nnnne!"Â
He was starting to become incoherent and you were loving it. The two of you were so close, you were on the cusp of a climax when Optimus's thumb pressed firmly on your clit. Your head slammed back in a silent cry and your walls held Optimus in a tight grip.Â
Optimus keened and shuddered as the charge became too much and he overloaded, his forehead on his berth right next to you. You looked left and saw him give a strained whimper and sob. You could fill his cum pump into you as he thrusts into you at a slightly slower pace. You looked down and saw how your belly was noticeably bigger.Â
Optimus got up, his arms on each side of you were trembling and shaking, your eyes met and he gave you a dumbed-out grin. You made a mental note to check in with Ratchet and make sure nothing got fried. You rubbed your belly and giggled, "I loved that optimus. And hey, I kinda look pregnant now."
As his eyes trailed down and he saw how swollen you got he made a choked moan.
You could feel him harden inside you. His jerked and he whimpered an overstimulated sob.
This made you concerned, "You alright sweetie?"
Through his tears he nodded. "P-p-pleeeesh c-can't stop but h-hurts nnggh!"Â
You tapped on his arm to get his attention, when you saw him making eye contact you spoke in a comforting and soft voice, "Hey hey, I know that you are feeling a lot right now. Are you sure you want to continue?" He nodded gulping down his sobs and pleading, "Ye-yes yes, please. Wa-want yooouuu."Â
You were still concerned but you trusted Optimu to know his limits, you propped yourself up on your elbows and purposely clenched around him. "Alright then, I still have some rooms to be bred and filled.Â
That set him going again as he rutted into you, even though he was beyond coherent this time he made sure to pay more attention to your clit. You couldn't think straight as you too could no longer see through the gog of pleasure. Optimus came with a loud scream, you followed immediately after.Â
Optimus pulled out and closed his panels before practically collapsing next to you.Â
After your breathing slowed down you called out to Optimus, "W-well that was...wow. How ya feeling.......Optimus?" You looked over and saw that he had passed out. Looks like aftercare was up to you.Â
After taking off your sweaty shirt and finding some cleaning rags you tied one around your waist and left the rest in a pile next to Optimus. You went to one of the storage closets in the hangar and got some sleeping bags and pillows. You went back to Optimus's room and put them on the ground before wiping down Optimus's panels and other areas. It was kinda hard because he was his true size but you didn't mind. It was when you were wiping his face he stirred back to the waking world.Â
"Welcome back to the world of the awake, how was your rest?" you asked as you wiped down his face.
He looked confused before everything came back to him, it showed on your face. "I apologize for falling into recharge. I have not...Interfaced like we did before."
"Oh, it's not a problem. I cleaned you and myself up by the way." pointing to your makeshift bottoms.Â
He looked down before a guilty expression graced his face, "I am sorry I was not present to administer after-interface care."
You waved him off as though it was no big deal because it wasn't. "Don't worry about it, I do have to ask though. What is the Cybertronian equivalent for a significant other?"Â
"We would call the term "Sweetparks.""Â
You climbed on his chest smiling, "Is that what we are now? Sweetsparks?"
He looked away, "I do not want to pressure you, but I would be honored to call you my sweet spark." Your smile was bright and happy, Optimus smiled as well. He was completely lovestruck.Â
You slept on some sleeping bags and pillows for padding on Optimus's chest. The two of you slept well in the warm embrace of each other.Â
