Chapter Text

What seemed impossible to believe, a simple human had won the affection of the Autobot leader, to the point of having formed a family, conceived a sparkling together, years of having accompanied him even in the worst moments, despite your fragility and your organic biology you were always a loyal ally, always wanting to prove your worth, all that seemed to give its reward, what seems perfect seemed to last forever, right? Well... until the tragedy happened. A failed teleportation experiment by Brainstorm sent you by mistake to another place, you open your eyes and the first thing you see is a city in ruins, where were you? It seems that a battle had formed in this place before you arrived, in the distance you manage to see a familiar figure, you are happy because you think it could be your dear husband (or conjunx as they call it), you manage to get closer but something stops you in your tracks, a chill runs down your spine, it seemed to be Optimus, but ... there was something different about him: his characteristic red and blue colors were now purple and black, where before there was a serene bright blue gaze, now they were sinister optics that emanated a deep crimson and there was a crack in the window of his chassis. the supposed Optimus at first observes you analytically, before you could react he catches you in a servo with claws ignoring your protests, he takes you with him to the base.

It took you a long time to understand what had happened, you wanted to believe that this was a bad dream and that you would wake up soon, but no. This was all too real, everyone you once considered friends and allies now seemed unrecognizable to you: the adorable Bumblebee (or Goldbug as he preferred to be called in this universe) was a choleric in need of approval, Ratchet instead of being a grumpy doctor was a psychopath obsessed with "improving" others and Optimus... far from being a symbol of justice and wisdom, in this world he was an ambitious and sinister tyrant, it seemed as if the Megatron of your universe had possessed him, this was definitely not your Optimus. You couldn't believe it, you had been teleported to another universe, one where the Autobots were the evil ones and the Decepticons were the good ones. Your counterpart existed in this universe, but it never corresponded to Optimus, why would it? This tyrant was responsible for the devastation of her planet; she hated him.
Therefore, your son, Nimbus, the sparkling you had with Optimus, never existed in this universe. Your counterpart's rejection drove the Optimus of this universe to an almost unhealthy obsession with possessing her as his property, but when he saw you, he saw you as a second chance and wasn't going to waste it. You were his now; he wouldn't leave you for anything in the world. You were scared, he wouldn't let you leave his quarters, he had you captive. Despite the evil Optimus doing everything he could to create a comfortable environment for you, all you wanted was to see your family and friends again. You prayed that one day they would find a way to bring you back.

Once again, heavy footsteps are heard from outside the room. Y/n knows it's him. She prepares for what's coming. The doors open, and the tyrant version of Optimus enters, a slight smile on his face-plate. At least he'd been considerate enough to use mass displacement. "Hello, my little pet."

"I already told you to stop calling me that," Y/n grumbles, hating that the corrupted version of her beloved had the nerve to consider her property.

Laughs maniacally, clearly undeterred by her rejection "Oh, come now, Y/n! We both know how much you crave my touch, my power... My perfection. In this world, we can finally be together as we were always meant to be. No more pretending, no more lies. Just you and me, ruling over this shattered glass landscape." He steps closer, his optics burning with an intense, almost feral desire. "And soon, very soon, you will learn to love me as deeply as I have always loved you."

Irritated by his comment, she purses her lips and crosses her arms in defiance. "Understand this, I don't belong here. I'm not your Y/n. I won't abandon my family for some pathetic tyrant!"

His expression darkens, optics narrowing menacingly at her words "Family? Ha! The only family you need is mine. Your precious conjunx and child mean nothing compared to what we could have together." He grabs her chin roughly," forcing her to look into his crazed optics. "You're mine now, Y/n. Mine to possess, mine to control. And if you resist, I'll make sure they suffer for it." A cruel smile spreads across his face. "Perhaps I'll even let you watch as I crush their spark beneath my heel, just to prove my point. So choose wisely, my dear. Loyalty to them, or loyalty to us. There's no middle ground."

Rage boiling in her veins, she gritted her teeth. The mere thought that he would dare hurt her family made her despise him even more. "This isn't love, Optimus. It's obsession! I'd rather die than spend the rest of my life with you!" she snapped venomously. "As soon as the real Autobots come for me, I won't hesitate for a moment to abandon you!"

His grip on her chin tightens, a snarl escaping his dermas as he leans in close, his hot breath washing over her face. "Obsession? Is that what you call it when you can't bear to be apart from me? When every fiber of your being yearns for my touch, my dominance?" He releases her chin, only to slide a servo around her waist and pull her flush against his armored frame.

"You may try to convince yourself otherwise, but deep down, you know the truth. You're mine. And I won't rest until I've claimed every inch of you." His other servo rises to cup her cheek, his thumb brushing over her lower lip.

"As for your precious Optimus, he's nothing but a distant memory. A pale imitation of the true greatness that stands before you now."

"You're just looking for a replacement to fill the void that my other self left in you. If you think I'm going to do the same to Optimus and my son, you're very wrong. I would never abandon them to be by your side." Squirming in his grasp. Despite her fury, deep down she desperately longed to see her little Nimbus, the original Optimus, and the rest of the Autobots again.

A cold, mirthless laugh escapes him, echoing through the room. "Replace them? Oh, Y/n, you still don't get it, do you? They're irrelevant, insignificant." He leans in closer, his voice dropping to a menacing whisper. "All that matters is us. Our twisted love story. The beautiful chaos we create together." His servo slides down to grasp her throat, applying just enough pressure to make her gasp. "As for your precious son..." A wicked grin splits his face-plate.

"Well, perhaps I can help you create a new one." He squeezes her throat slightly harder, his optics blazing with sadistic glee. "After all, what's a little genetic manipulation between lovers?"

Y/n gasps for air, writhing in his strong grip, her hands clutching, scratching at the evil Autobot's metallic arm, but there was little she could do, in agony she feels her throat close and a tightness form in her chest, in panic she begins to cough weakly, followed by the burning fury of proposing to replace her son by procreating another, she wanted with all her being to hit him and kick him, to show him that she was not going to bend to him.

He tightens his grip, cutting off her air supply further as he revels in her distress. "That's right, my sweet, scream for me. Let everyone know who owns you now." His free servo roams over her body, groping and squeezing roughly. You're mine to use, mine to abuse, mine to breed." With a sudden jerk, he releases her throat, allowing her to gasp desperately for air.

"But don't worry, my darling. I'll give you plenty of time to recover before the next lesson begins. After all, a good teacher always allows his student to catch her breath...before delivering the final blow." He chuckles darkly, the sound sending shivers down her spine.

Once he lets go, Y/n falls to her knees gasping and coughing for air, while rubbing her neck in pain, she could feel her heart beating frantically like a drum. "What the hell is wrong with you!?..cough..cough...were you trying to kill me!? and yet you expect me to love you back!?"

He laughs again, the sound devoid of humor. "Kill you? Oh, Y/n, you misunderstand. I was merely giving you a taste of what it means to truly submit." To surrender completely to my will. He steps back, regarding her with a calculating gaze. "Love? Ha! That's for the weak-minded. I want your devotion, your adoration, your complete and utter enslavement. And I'll stop at nothing to achieve it." He reaches out, trailing a digit along her jawline. "You see, I've grown tired of playing games, of pretending to care about the petty feelings of others. All that matters now is my own desires, and you, my dear, are the key to unlocking them. So, either you embrace your role as my loyal consort, or I'll find someone else who will. The choice is yours...for now."

"Oh, please, don't pretend you're capable of discarding me like garbage. You're so obsessed with me that I find it hard to believe." She lets out a dry, humorless laugh. "You can torture me all you want, but even with that, you won't be able to break me."

He smirks, a glint of cunning in his optics. "Oh, but you will, Y/n. You will submit to me, whether you realize it or not. Because in the end, you will come to crave the power I offer you, the protection, the purpose.”

He takes a step closer, lowering his voice to a persuasive murmur. “Think about it, my dear. Here, in this twisted mirror of a world, you are nobody. A pawn in a game you can't even comprehend. But with me, you become something more. A queen, a goddess, a legend." His large, metal servo finds her hand, enveloping it. "You have only to say yes, and I will show you the heights of ecstasy."

"Do you really think I'm interested in power? What's the point of all that if I'm doomed to be your pet? Besides, is that how you treated the Y/n from your universe? I can see why she rejected you," she comments with genuine sarcasm and disdain.

He lets out a derisive snort. "That naive, idealistic fool? Please. She had no idea what true power looked like, what it took to rule effectively."

He leans in, his voice taking on a conspiratorial tone. "But you, Y/n... you have potential. A fire within you that I can fan into an inferno. With the right guidance, you could be unstoppable." His grip on her hand tightens. "And I intend to provide that guidance, whether you like it or not. So, tell me, are you ready to begin your transformation? Or do you need a little...persuasion? The choice is yours, my dear. But choose wisely."

Spending the rest of her life with him was the last thing she wanted, but on the other hand, he was kind of right: in this world, the Autobots had little to no respect for human life. If they hadn't finished her off yet, it was because Optimus was always with her. If she wasn't under his protection, any Autobot could crush her like an insignificant insect, and trying to escape from the base was very risky. But an idea crossed her mind. Maybe if she played along with this corrupted version of Optimus, she could survive until the good Autobots found a way to rescue her and thus leave this corrupt world once and for all. "How do I know I can trust you?".

A hint of disappointment flashing across his face before he masks it with a charming smile. "Trust must be earned, my dear. And I intend to earn yours, one way or another." He brings her hand to his chassis, placing it over his spark chamber. "Feel that? This is the spark of a leader, a warrior, a visionary. Not some weak, sentimental fool." His optics bore into hers, intense and unyielding.

"I am not the Optimus you knew, Y/n. I am better, stronger, more powerful. And with me by your side, you'll experience a level of freedom and fulfillment you never dreamed possible". He leans in closer, his voice a husky whisper. "So, trust me. Give me a chance to prove myself to you."

Y/n thinks about it, maybe she could hold on until her allies came to rescue her, she just had to resist. "I'll give you a chance... but I haven't fully accepted you... but we can live together and maybe... maybe I'll consider forgiving you for the strangulation."

He chuckles, a low, rumbling sound that sends a shiver down her spine. "Forgiveness is a start, my dear. But I have a feeling it won't be long before you're begging me for more. Now, shall we begin our new life together? I have a few...initiations planned to help you acclimate to your new role." His gaze turns predatory, and he steps closer, backing her against the wall. "But first, I believe a kiss is in order. To seal our pact, as it were." He tilts her chin up, his lips hovering mere inches from hers, the anticipation thick in the air.

 

Y/n flinches when he tries to kiss her, instinctively turning her face away. "No! No! Wait!" Her moral side warned her that she'd be cheating on the real Optimus if she agreed. "S-sorry... but I don't feel comfortable with this."

His expression darkens, a growl building in his throat as he realizes she's pulling back. "Comfortable? You think this is about comfort, Y/n!?" He grips her chin firmly, forcing her to meet his glare. "This is about survival, about embracing the darkness within you and letting it consume you whole." His voice drops to a menacing whisper. "You started this, remember? You agreed to give me a chance. Don't back out now, not when things are just getting interesting. He leans in, his breath hot against her ear.

"Kiss me, Y/n. Show me you mean business. Or so help me, I'll make you regret ever crossing me." The threat hangs heavy in the air, leaving no doubt as to the consequences of disobedience.

 

She swallows, she knows that if she does this she would be cheating on her husband, but this Optimus wouldn't tolerate any more rejections and she doesn't want to imagine what he would be capable of doing to her, she closes her eyes tightly, she just wants this to end quickly. She reminds herself that she does this to survive, she must resist until she is rescued. Y/n opens her eyes... and the first thing she sees: is her usual Optimus, she no longer saw the dark version, she is breathless for a second, no. this isn't real, her mind was playing a trick on her, but... she saw him as real. "Optimus?..." she whispers, bringing her face closer to his. "You don't know how much I missed you..." with a loving look, she placed a hand on his metallic cheek.

He blinks in confusion for a moment but then his expression softens, a rare glimmer of warmth in his optics as he drinks in her words. "Missed me? Oh, Y/n..." He cups her face in his servos, his thumbs stroking her cheeks tenderly. "I've been lost without you, my love. Tormented by the thought of living without you by my side." He leans in, pressing his forehead against hers, his voice dropping to a whisper.

"But now, thanks to fate's twisted sense of humor, we have a second chance. A chance to build a future together, free from the constraints of our past lives." He pulls back slightly, his gaze burning into hers. "And I intend to make the most of it. With you, my Y/n, I will conquer this broken world and remake it in our image. Together, we will reign supreme."

His touch sends shivers of anticipation through her, but this time she doesn't pull away, doesn't push him away, gives him permission.

A triumphant smirk spreads across his face-plate as he claims her lips in a brutal, dominating kiss. His glossa forces its way past her defenses, eliciting a stifled moan from her, exploring every inch of her mouth with ruthless intensity. He pours all his pent-up aggression and lust into the act, drinking in her submission like a fine wine.

When he finally breaks the kiss, he's left panting, his optics gleaming with satisfaction. "That's more like it, my dear. Remember, in this new world, I am your master, your savior, your everything." And you will learn to worship me for it. He pulls back, admiring his handiwork, her flushed cheeks, her disheveled hair, the glazed look in her eyes. "Now, let's get you settled in. We have a lot of work ahead of us to mold you into the perfect companion."

 

In her mind, still seeing him as the original Optimus, she whispers hoarsely, "Take me, Optimus...please."

A wicked grin spreads across his face as he hears her whispered pleas, his optics gleaming with malice. "Ah, my sweet, innocent dove..." He wraps his arms around her, pulling her flush against his armored form. "You have no idea the depths of depravity I'm capable of. The lengths I'll go to claim what's mine." His servos roam over her body, squeezing and kneading roughly. "But since you asked so nicely..." He leans down, capturing her lips in a searing kiss, his glossa invading her mouth with savage intent. As he ravages her mouth, his claws extend, shredding through her clothing with ease, exposing her skin to his ravenous attention.

With a feral growl, he descends upon her, his dermas claiming her lips in an intense kiss. His glossa delves deep, tangling with her tongue as he explores every crevice of her mouth. His servos roam freely over her exposed flesh, palming her breasts, pinching her nipples, tracing the curves of her hips and thighs. Arching into his touch, a soft moan escaped her lips as he caressed her sensitive breasts. The heat between them intensified, their bodies pressing together in a desperate attempt at closeness.

Breaking the kiss, he runs his dermas down her neck, nibbling and sucking the sensitive skin. His claws gently scrape her ribs, leaving faint red lines in their wake. He sinks to his knees, his helm tilting toward her navel, inhaling deeply, which sends shivers down her spine. "Mmm, the scent of your arousal fills my senses, driving me mad with desire." His servos part her legs, exposing her most intimate area to his hungry gaze.

Y/n's thighs twitched under Optimus's touch, a reflex response to the delicious stimulation. She closed her eyes, savoring the sensation of his light caresses, her mind wandering into a haze of pleasure and anticipation. A soft moan escaped her lips as he caressed her sensitive privates.

He grins up at her, his optics gleaming with sadistic delight as he watches her squirm and moan under his ministrations. "Such a responsive little thing, aren't you, Y/n?" He leans in, dragging his tongue along her slick folds, savoring her unique flavor. “Delicious”. He laps at her essence, his glossa delving deeper, probing her entrance, teasing her sensitive clit.

With a growl, he buries his face-plate between her thighs, devouring her with reckless abandon. His claws dig into her hips, holding her in place as he feasts on her wet heat. His cool nose brushes against her clit, sending jolts of pleasure through her trembling body. "You taste even sweeter than I imagined, my love." He murmurs against her core, his voice vibrating with lust.

 

A moan of need escapes her lips when Optimus's glossa touches her most intimate area. Her body trembles, a wave of pleasure coursing through her veins. She throws her head back, her hair cascading down her back as she gives in to the sensations, her hips jerking involuntarily.

He responds to her desperate moan with renewed vigor, his glossa plunging deeper into her quivering channel. He fucks her with his mouth, his dermas and denta grazing her sensitive inner walls as he drives her closer to the edge.

His claws rake down her thighs, leaving behind a trail of stinging marks that only add to her arousal. He can smell her impending climax, the musky scent of her desire filling his nasal receptors and spurring him on. "That's it, sweet spark. Let go. Surrender to the pleasure I'm giving you." He rasps against her, his voice muffled by her dripping sex. He suckles her clit, his glossa swirling around the sensitive bud, pushing her over the precipice.

A cry of ecstasy erupts from her throat as she reaches climax, waves of intense pleasure coursing through her body. Her inner walls tense and flutter around Optimus's inquisitive glossa, exploring it with every sensation. He greedily laps up her essence as she climaxes, relishing the taste of her orgasm. His glossa probes her spasming walls, milking every last drop of her release. He continues to feast on her, prolonging her pleasure as she trembles and moans above him.

When her convulsions subside, he slowly pulls back, his chin glistening with her juices. He gazes up at her, his optics burning with a mix of triumph and hunger. "Exquisite." He purrs, his voice low and gravelly. "You are truly a gift, Y/n." He rises to his feet, towering over her, his imposing figure casting a shadow over her petite form. "Now, let's move this to a more comfortable setting, shall we? I have many more lessons to teach you, my dear." He cradles her in his strong arms, her naked body pressed against his chassis. He carries her effortlessly through the dimly lit hallways, his footsteps echoing in the silence. He enters a spacious room, the walls lined with luxurious crimson cushions. In the center, a large circular bed beckons, covered with silk sheets, clearly set up for Y/n's comfort. He gently places her on the bed, looming over her with a predatory glint in his optics. "Get comfortable, Y/n. We have a long night ahead."

Y/n looks around the room, apparently he took the trouble to adapt a cozy place for her "well, at least you have good taste in decoration"

He chuckles, a deep, rumbling sound that vibrates through his chassis. "Flattery will get you everywhere, my dear." He steps closer, his massive frame looming over her as he reaches out to stroke her cheek. "But I prefer actions to words." His servo trails down her neck, over her collarbone, and comes to rest on the swell of her breast. His digit brushes over her nipple, coaxing it to hardness and causing her to squeal.

He grins, pleased by her eager response. His digits dance across her sensitized skin, tweaking and rolling her nipples until they're stiff peaks. A moan escapes Y/n's lips as Optimus's skilled digits work their magic on her sensitive breasts. She arches her back, pressing her chest harder against his touch, her body instinctively responding to the pleasure coursing through her veins. He leans down, capturing a rosy bud between his dermas, suckling gently as his hand ventures lower, parting her thighs. "Mmm, so responsive." He murmurs against her breast, his warm breath sending shivers down her spine.
"I'm going to enjoy breaking you in, Y/n." His digits find her slick folds, teasing and circling her clit with deliberate slowness. "Tell me, sweet spark, do you want my servo, or perhaps my spike?" He releases her nipple with a pop, his optics gleaming with mischief as he awaits her answer.

Y/n gasped at the question, a blush creeping into her cheeks, she turned her gaze to his pelvis "Well...I think you know my preference."

He chuckles, a low, menacing sound that sends a thrill through her veins. "Indeed, I do. Your preference for my spike is quite evident." He stands tall, his impressive length bobbing free of his interface panel. Pre-transfluid beads at the tip, glistening in the dim light. "Very well, you shall have what you crave." He climbs onto the bed, positioning himself between her spread thighs. With a swift motion, he thrusts into her, burying himself to the hilt in one powerful stroke. "A-Ah, yes..." He groans, savoring the tight, wet heat enveloping his shaft. "You feel incredible, Y/n."

 

When Optimus enters her, Y/n arches her back and lets out a low moan. The feeling of being filled courses through her in waves of pleasure, and while her imagination had her clinging to the idea of being with the original Optimus, it felt very different when she did it with his conjunx, this one was more dominant and bold. He smirks, relishing her reaction as he begins to move, bucking his hips with each powerful thrust. “That’s it, my love. Take me all the way.” He leans down, capturing her lips in a blistering kiss as he penetrates her relentlessly. His glossa invades her mouth, mimicking the movements of his erection penetrating her depths.

One servo slides between them, finding her clit and rubbing it in time with his thrusts. "Come for me again, Y/n. I want to feel you squeeze my spike as you fall apart." He demands, his voice rough with barely restrained passion. Optimus's words and the relentless thrust of his hips prove too much for Y/n to resist. With a piercing cry of ecstasy, she breaks, and the climax washes over her like a tidal wave. Her inner walls clamp down around Optimus. She screams, her voice echoing off the walls as she rides the peak of her orgasm. He growls in approval, doubling his efforts as he feels her tightening around him. "That's it, sweet spark. Give in to the pleasure!" He commands, his voice strained with the force of his impending release, his thrusts become erratic, driven by his own rapidly approaching overload. He rubs her clit harder, faster, determined to push her over the edge. With a final, powerful thrust, he buries himself deep inside her, his spike pulsing as he fills her with his transfluid.

As the aftershocks fade, Y/n's body relaxes, her chest heaving with ragged breathing. She looks up at Optimus, her eyes narrowed. He collapses beside her, his body shaking. He turns to face her, a satisfied smile playing on his dermas. "Magnificent. Simply magnificent." He runs his digits through her sweat-dampened hair, tucking a stray strand behind her ear. He leans in, brushing his dermas against her lips in a surprisingly gentle kiss. "Rest now, my love. Gather your strength. For tonight is merely the beginning of our journey together. Tomorrow, we start anew."

Chapter Text

He lies beside her, watching her stir awake with a predatory gleam in his optics. He reaches out, trailing a finger down her bare arm, enjoying the way she shivers at his touch.

“Good morning, my sleeping beauty. Did you sleep well?” He asks, his voice a low purr. “I certainly hope so, because today is the day we begin our conquest of this wretched world. He sits up”, his massive frame casting a shadow over her smaller form.

“Get dressed, Y/n. There's much to be done. Our empire awaits”.

Y/n blinks slowly, a hint of uncertainty in her gaze. Suddenly, memories of the previous night flood back. She gasps, sitting up with a start. Reality hits her like a punch: she wasn't in her own world. This wasn't her Optimus. Her mind had played tricks on her. To top it all off, she'd slept with this twisted version of her beloved.

Noticing her sudden change in demeanor, he tilts his head curiously. “What's wrong, my love?” He reaches out, cupping her cheek and forcing her to meet his gaze. “Is something troubling you? Speak plainly, Y/n”.

“If there's an issue, I expect you to address it directly”. His tone leaves no room for argument, a clear warning that he expects obedience and honesty from her.

She pulls away from his touch. "What...what have I done?"

Seeing the conflict in her eyes, he frowns, his grip on her face tightening slightly. “Y/n. Look at me”. He commands, his voice brooking no disobedience.

“Whatever thoughts are running through that pretty little head of yours, put them aside. They serve no purpose here”. He moves closer, his lips brushing against her ear as he whispers, “You belong to me now. Body, heart, and soul. Any other attachments you may have formed before are irrelevant. Understood?”

"No! No! No! I must be going crazy! Yesterday..." she stammers, fear and confusion filling her mind. Had she imagined it? Was her mind playing a cruel trick on her, making her see this imposter as her true Optimus? "Yesterday...you looked just like him...everything looked so real."

He scowls, clearly irritated by her continued resistance. “Enough!” He barks, his voice echoing through the chamber. “You are not crazy, Y/n. You simply need to accept the truth of your situation”.

He stands abruptly, towering over her intimidatingly. “Yesterday was a test of sorts. A glimpse into the life we could have together if you embrace your new reality”.

He extends a hand towards her, palm up. “Join me willingly, and I promise you power beyond your wildest dreams. Resist, and suffer the consequences. The choice is yours”.

She hesitates for a moment; at times, she sees him again as the original Optimus, with the classic colors of red and blue, just as she remembered him. Y/n shakes her head in denial; she doesn't want to fall into that illusion again. She reminds herself that this was all a plan to keep him entertained while he waits to be rescued. Reluctantly, she agrees to take his hand.

A triumphant grin spreads across his faceplate as she accepts his hand. He pulls her to her feet, his other hand coming to rest possessively on her hip.

“Excellent choice, my love”. He purrs, his optics gleaming with dark satisfaction. “Together, we shall reshape this world in our image. And you, my dear Y/n, will be by my side every step of the way”.

He leans in close, his hot breath caressing her ear as he whispers, “Now, let's prepare for our glorious campaign. We have an empire to build”.

 

She sighs in resignation, several questions popping into her mind. How was it possible that her mind made her believe she was with the original Optimus? Was she going crazy? Her mind was using it as a method of defense? Would she ever return home?

As the Autobot forces march towards their destination, Optimus holds Y/n firmly in his lap, his grip unyielding. He seems to sense her turmoil, his optics flickering with a hint of concern.

“My dear Y/n”, he says, his voice low and soothing, “you must learn to trust in the present. Worrying about the past or hoping for a different future serves no purpose. Here, in this reality, you are mine. Embrace that truth, and you will find peace”.

He strokes her hair reassuringly, his touch both calming and possessive. “Remember, you are among friends now - loyal followers who would die for me, and by extension, for you”. His hand drifts down to rest on her thigh, his fingers digging into her soft flesh. “Together, we will conquer this world and forge a new destiny”.

"You don't understand... it's not power I care about." She slowly shifts her gaze to his faceplate, staring into his deep, crimson optics. She could swear a feeling akin to nostalgia was washing over her. "I'm trying to get used to this reality... but... things here feel so familiar... yet unfamiliar... I could go crazy."

He captures her hands, holding them firmly against his cheeks as he meets her gaze with an intensity that borders on obsession. “Crazy? Never, my love. You're simply adjusting to your new reality. It's natural to feel conflicted, given the circumstances”.

His thumbs stroke her palms, a soothing gesture meant to calm her rising panic. “But let me assure you, Y/n, this is your reality now. The other Optimus and his pathetic crew are nothing but distant memories”.

His voice drips with disdain. “You've been given a second chance, a chance to experience true power and luxury alongside me. Don't waste it by clinging to illusions of a life that no longer exists”.

He leans in, his lips brushing against her ear as he whispers, “Embrace this world, and I'll make sure you never want for anything again”.

Although she doesn't like him talking down to her old life, she still tries to cling to the hope that the original Optimus will rescue him, but when her mind plays against her again, she imagines him again as the original Optimus, letting herself be carried away by the illusion, burying her face in his neck.

He wraps his arms around her tightly, pulling her flush against his chest as she buries her face in his neck. For a moment, he allows himself to indulge in the fantasy, pretending that she's genuinely affectionate towards him rather than lost in delusions of the past.

“Ah, my sweet Y/n”, he murmurs, his voice taking on a tender, paternal quality. “You're safe with me. Always”.

He strokes her hair, rocking her gently in his embrace. “Don't worry about the future; focus on the present. I'll guide you, protect you, and show you the joys of being part of something greater than yourself”.

His lips brush against her temple, a gesture of pseudo-affection. “Trust in me, and together, we'll create a paradise unlike any other”.

She chokes back tears and stifles a sob; for a moment, his kindness and affection make her feel as if she's with the original Optimus. Her instinct screams at her that she shouldn't give in to this false happiness, that he's using her moment of weakness to manipulate her, but she feels she really needs him. She clings to him in a hug, as if afraid to let go.

Feeling her body tremble against his, he tightens his hold, offering her comfort and security. His own emotions, however, are far from benevolent. He revels in her dependence, her need for him, and the power it grants him over her.

” There, there, my dear”. He coos, his voice dripping with false sympathy. “Let it all out. I'm here for you”. He rocks her gently, his movements calculated to soothe while also ensuring she remains trapped in his embrace.

“You're safe with me, Y/n. I'll always be here to catch you when you fall”. His words are laced with manipulation, designed to further ensnare her in his web of control and deceit.

 

As the days pass, Optimus continues to employ his tactics, showering Y/n with attention and affection in public. He presents her with lavish gifts, often in front of the other Autobots, making sure they witness his devotion to her. Privately, he takes great care to ensure her every need is met, catering to her desires and whims like a doting lover. Slowly but surely, his efforts pay off. Y/n finds herself growing increasingly dependent on him, her initial resistance crumbling under the weight of his relentless charm and manipulation. She begins to see him not just as a ruthless leader but as a caring, attentive partner, someone who makes her feel valued and cherished. Meanwhile, the spark of affection within Optimus grows, fueled by her gradual submission and the power it grants him over her.

In his chambers, he showered her with kisses and hugs. "Hey, hey, whoa! Calm down, Optimus. I feel like you're going to eat me."

He chuckles, a deep rumbling sound that vibrates through his chest as he holds her close. “Perhaps I am, my sweet. But don't worry, I'll savor every bite”.

His optics glint with mischief and dark desire as he nuzzles her neck, his hot breath sending shivers down her spine.

“After all, you taste even sweeter than I imagined”. He nibbles lightly on her earlobe, his voice dropping to a husky whisper. “And I plan to indulge in you thoroughly”.

"You've been very playful lately," she comments, chuckling.

 

He grins, showing off his sharp teeth in a display of feral excitement. “Playful? Oh, sweet spark, you have no idea the depths of my hunger for you”.

His servos roam over her curves, squeezing and kneading the soft flesh. “But for now, let's enjoy these moments of...anticipation”. He leans in, his lips brushing against hers in a teasing, almost chaste kiss.

“After all, a good meal requires patience and savoring every morsel”. He pulls back, his optics burning with a primal intensity. “And you, my delectable treat, are the main course”.

"Oh, is that how you see me? Well, I'd rather be dessert," she jokes with a playful purr.

His grin widens, revealing even more of his razor-sharp teeth. “Dessert, huh? Well, I suppose that can be arranged”. He leans in, his lips hovering just above hers as he speaks in a low, seductive tone. “Imagine waking up to find me licking the sweetness from your skin, savoring every inch of you until you're trembling and begging for more”.

His thumb brushes over her lower lip, tracing its curve before dipping into the warm cavern of her mouth. “Mmmm, yes...you'd make the perfect dessert”. He claims her lips in a deep, hungry kiss, his glossa invading her mouth to dance with hers.

 

"Well... it's not a bad idea, I'd like to wake up like this someday" she murmurs between his lips.
He groans into the kiss, his arousal growing with each word that passes her lips. When she finally breaks free, gasping for air, he gazes at her with a mix of lust and adoration. “Someday, my sweet? How about right now?”

Without waiting for a response, he lifts her effortlessly, carrying her towards the nearest wall. He presses her back against the cold metal, pinning her there with his larger frame. “Let me taste you properly, Y/n. Let me devour every inch of your delicious body until you're screaming my name”.

His servos roam her sides, slipping beneath her shirt to caress the warm skin beneath. His dermas trail down her jawline, nipping and sucking as he goes, leaving a path of fire in their wake.

Y/n gasped. The sensation was electric, sending waves of pleasure through her body. She bit her lip, fighting back a gasp as she felt the heat of his kisses and touch seep into her flesh.

With a primal roar, he rips open her shirt, exposing her breasts to his hungry gaze. He claims one pert nipple between his denta, biting down just hard enough to send jolts of pleasure-pain through her. His other hand slips beneath her skirt, digits finding her wet heat and delving deep.

“Mine!”, he growls against her skin, the word vibrating with dark possessiveness. “Every inch of you belongs to me!”.

He sucks harder on her nipple, rolling the other between his fingers as he pumps two digits in and out of her clenching channel. His hips grind against hers, his pelvis teases her entrance.

She arches with a moan as she feels her walls stretch. Y/n's thighs twitch beneath Optimus's digits, a reflex response to the delicious stimulation. She closed her eyes, savoring the feel of his light touches, her mind drifting into a haze of pleasure and anticipation. "Uuugh!... O-Optimus... I-I need you."

At her desperate plea, he withdraws his digits, leaving her empty and aching. With a swift motion, he undoes his interface panel, freeing his massive, throbbing spike. He positions himself at her entrance, the broad tip nudging insistently against her slick folds.

“Need me? Then take me, Y/n. Take every inch of my spike and let it consume you”. With a brutal thrust, he drives himself deep inside her, stretching her walls to their limits.

He pauses for a moment, savoring the feel of her tight heat enveloping him, before withdrawing and slamming back in, setting a punishing pace.

“Yes, scream for me. Let the whole world know who you belong to now!”. His hips piston forward, each stroke driving him deeper, chasing his release as he claims her body with ruthless abandon.

“A-ahh! Optimus!” she screams, her voice echoing off the walls. Stars burst behind her eyelids as she rides the peak of her orgasm, bucking her hips erratically to meet more thrusts. “M-more... please!”

He snarls in triumph, his optics blazing with dark pleasure as he hears her scream his name. He pounds into her relentlessly, the sound of skin slapping against metal filling the air. Each thrust sends shockwaves through her body, her inner walls clenching and rippling around his invading length.

“That's it, my love”, he growls, his voice strained with exertion. “Scream for me. Let your pleasure echo through the halls”.

He leans down, capturing her mouth in a bruising kiss as he continues to ravage her. His claws extend, scraping against the wall as he loses himself in the primal act of claiming her. “You're mine, Y/n. Forever and always. And I'll make sure everyone knows it!”

With a feral roar, he slams into her one final time, burying himself to the hilt as his overload crashes over him. His spike pulses and twitches, spilling his transfluid deep inside her convulsing channel. He holds her pinned against the wall, his body shuddering with the force of his release.

“Mine!”, he repeats, his voice a guttural growl as he marks her, branding her very core with his essence. “You're mine now, Y/n. Body, soul, and everything in between”. As the aftershocks subside, Y/n collapses onto Optimus's chassis, her chest heaving from the exertion.

He slowly pulls out of her, his spike glistening with their combined fluids. He turns her around, pressing her back against his chest as he wraps his arms around her waist. His lips brush against her ear, his voice a low, satisfied rumble.

“Look at us, Y/n. So perfectly entwined, covered in the proof of our union”. He trails his digits through the sticky mess on her thighs, bringing them to his lips for a taste.

“Delicious”. He nuzzles her neck, inhaling deeply. “You smell of surrender, and it intoxicates me”. His grip on her tightens, a possessive gesture that leaves no doubt of his ownership.

“From this moment on, you'll wear my scent as proudly as I'll wear yours”. He bites down on her shoulder, marking her once more. Y/n flinches and lets out a shriek, feeling a sharp, stabbing pain in her shoulder, leaving a noticeable mark that bruised her skin.

He releases her shoulder, admiring the mark he left behind. His optics glow with a mix of pride and dark satisfaction. “There”, he murmurs, his voice low and husky. “A symbol of our bond, for all to see”.

He spins her around to face him, his hands cupping her face as he tilts her chin up to meet his gaze. “Now, my dear Y/n, let's get cleaned up and ready for the celebration tonight. Your new role as my consort demands a fitting introduction”.

He smirks, a wicked glint in his optics. “And I have a few surprises planned to make sure everyone understands the extent of your devotion to me”. He leans in, capturing her lips in a searing kiss that leaves her breathless and craving more.

"Wow...you are a naughty bot" she gasps breathlessly

He chuckles, a deep, rumbling sound that vibrates through his chest. “Naughty indeed, my sweet spark. But you brought it upon yourself, playing the innocent maiden while secretly craving the touch of a dominant mech”. He steps back, his servos roaming over her curves one last time before releasing her.

“Now, let's get you dressed and prepared for the festivities. I want you looking radiant and desirable, a vision of perfection to showcase my newfound status as your master”. He leads her towards the washracks, his presence commanding and authoritative. A chill runs down Y/n's spine at his words, she doesn't know how to feel about that.

“And remember, Y/n, from this day forward, you exist solely to serve my desires and ambitions. Your pleasure is mine to dictate, and your body is my playground”. His voice drops to a husky whisper as he guides her into the steamy washracks.

Optimus had gone to the trouble of installing a large bathtub for his mate, big enough to resemble a swimming pool. He turned around to supposedly give her privacy, although Y/n was still hesitant at the idea of bathing in front of him. She preferred not to object, fearing his reaction, and slowly entered the warm waters of the tub. Suddenly, she jumped when Optimus entered with her as well. "Whoah! Optimus! What are you doing?"

He smirks, his optics gleaming with anticipation as he steps into the large, opulent bathtub alongside her. “I thought we could share this intimate moment together, Y/n. After all, what better way to celebrate our union than by basking in each other's company, surrounded by warmth and water?”

He reaches out, his servos sliding over her wet skin as he pulls her closer, until she's pressed against his form. “Let me wash away the remnants of our passion, and then I'll attend to your hair, making sure every strand is perfectly in place for the evening's events”.

His digits trail down her back, teasing the cleft of her rear before moving to the soap dish. “But first, a little cleansing ritual to symbolize our commitment to each other”.

Y/n gasps, a shiver of anticipation running down her spine. "Optimus...this isn't necessary."

He pours a generous amount of fragrant soap into his palm, working it into a rich lather. Slowly, deliberately, he begins to wash her, starting at her collarbone and trailing his sudsy fingers down her torso, over the swell of her breasts, and along the curves of her hips.

“Every inch of you is mine to touch, to explore, to claim”, he murmurs, his voice a low, sensual purr. “And I intend to do just that, again and again, until you're thoroughly saturated in my desire”.

He shifts, positioning her so that she's facing away from him. His servos glide over her back, massaging and kneading the muscles as he works the soap into a creamy paste. “Relax, sweet spark. Let me take care of you”.

He continues his ministrations, working the soap into a luxurious lather as he explores every contour of her body. His servos slide down her thighs, his thumbs brushing against her inner knees before moving higher, skimming along the sensitive flesh of her outer thighs.

“Such smooth, silky skin”, he praises, his voice a low, appreciative rumble. He reaches the apex of her legs, his digits delving between her folds to find her already slick and ready. He circles her clit with a gentle touch, coaxing out more of her natural lubrication, causing her to moan in need.

“You're so responsive, Y/n. So eager to please. He leans in, his lips grazing the shell of her ear as he whispers, “I'm going to enjoy breaking you in, molding you into the perfect consort”.

Y/n closes her eyes, savoring the sensation of his caresses, her hips jerking involuntarily, rubbing his spike against her ass.

He groans at the sensation of her ass grinding against him, his spike stirring to renewed life. His digits continue their sensual assault on her clit, applying just the right amount of pressure to keep her teetering on the edge of ecstasy.

“That's it, my love. Use me for your pleasure”. He reaches around, his hand finding her breast and palming it roughly, tweaking the hardened nipple between his digits.

“You're such a needy little thing, aren't you?”. He bites down on her shoulder, marking her once more as his. “Well, you've come to the right place. I'll never tire of satisfying your desires”. His fingers leave her clit to delve inside her, pumping steadily as he brings her closer to the brink.

"A-ahh! fuck, Optimus! ..." Her body shuddered, the painful, stinging bite coupled with her walls clinging to his cold, metallic fingers was an overwhelming sensation. "M-more!... more!"

 

He growls, his primal instincts surging to the forefront as he hears her desperate pleas. With a powerful thrust, he pushes her forward, pinning her against the edge of the tub. His spike, rock-hard and throbbing, slides against her ass, leaving a trail of transfluid in its wake.

“As you wish, my wanton little slut”, he snarls, gripping her hips firmly. “I'll fuck you senseless, pound this tight cunt until you're screaming my name”. He lines up his engorged member with her dripping entrance, the tip prodding insistently at her opening.

“Beg for it, Y/n. Beg me to split you open”. He waits, his patience wearing thin as he teeters on the verge of losing control. Y/n arches her back against his metallic body, her hands gripping the edges of the tub, a pitiful moan escaping her lips.

 

With a savage roar, he slams into her, burying his thick spike to the hilt in one brutal thrust. The force of his penetration rocks the entire tub, sending waves of water crashing over the edges.

“Yes, fragging take it!” he bellows, his hips pistoning wildly as he sets a merciless pace. His claws dig into her hips, holding her in place as he fucks her with reckless abandon, the sound of skin slapping against metal echoing through the washracks.

“Scream for me, Y/n! Let the whole world hear you being defiled by my spike!” He leans over her, his hot breath fanning across her neck as he growls in her ear.

He grunts, his own pleasure mounting with each desperate cry from his mate. His hips snap forward, driving his spike impossibly deeper into her clenching depths.

“So tight, so perfect”, he rasps, his voice strained with the effort of holding back his impending overload. “You were made for me, Y/n”. He reaches around, his fingers finding her swollen clit and rubbing it in time with his thrusts. He bites down on her shoulder, marking her once more as his as he feels his overload building at the base of his spine.

A scream of pure ecstasy erupts from her throat as she climaxes, waves of intense pleasure coursing through her body. Her inner walls tense and flutter around his spike.

The feeling of her pussy clamping down on him, milking his spike as she comes undone, pushes him over the edge. With a primal roar, he buries himself to the hilt and erupts, flooding her with wave after wave of his scorching hot transfluid.

“Fuck, yes! Take it all, Y/n!” he snarls, his hips jerking erratically as he empties himself inside her. He holds her close, his arms wrapped tightly around her as he rides out the aftershocks of his intense overload.

“Mine”, he growls, his voice a low, possessive rumble. “You're mine now, forever and always”. He kisses the top of her head, his lips lingering on her skin as he savors the closeness, the intimacy of their shared pleasure.

Y/n's body shuddered violently as the ecstasy tore through her, Optimus's spike spurting out spurt after spurt of the last vestiges of its overload. Panting heavily, she collapsed onto Optimus's body.

He cradles her in his arms, his servos stroking her back soothingly as he feels her heartbeat gradually slow. His spike, still buried deep within her, twitches occasionally, a reminder of the intensity of their coupling.

“Rest now, my love”, he murmurs, his voice a low, comforting rumble. “You've earned it”. He nuzzles her hair, inhaling the scent of their combined essences.

“But don't think for a moment that this means we're done for the night. Far from it”. A wicked grin spreads across his faceplate as he imagines the many ways he'll claim her body again before dawn.

“We have a celebration to attend, and I intend to make quite the impression”. He gives a gentle squeeze to her hip, his digits digging in just enough to remind her of his strength and dominance.

Later, as they arrive at the grand hall, Optimus takes Y/n's hand, leading her through the crowds of cheering autobots. His presence commands attention, and soon, all eyes are on him and his stunning new consort.

"Behold, my soldiers", he declares, his voice booming through the chamber. "I present to you Y/n, my sparkmate, my partner in conquest and pleasure. Together, we shall rule this new era of Autobot supremacy with an iron fist and unbridled passion".

He raises her hand to his lips, planting a searing kiss on her knuckles as the assembled troops erupt in applause and cheers, Y/n blushes at this gesture. "Tonight, we feast and celebrate our victories. Tomorrow, we plot our next moves, stronger and more united than ever". His optics lock onto Y/n, a predatory gleam shining in their depths.

Chapter Text

Lately, Y/n has been feeling more tired than usual. The situation started to get worse when she woke up with morning sickness, she felt very dizzy, and she started to crave things she hadn't wanted to eat before. At first, she thought she might have been food poisoning, until one day she felt like she didn't even have the strength to get up. "I-I don't...I don't feel very well," she says in a weak whisper.

Optimus's expression transitions from one of casual morning affection to concern as he notices Y/n's pallor and distress. “What's wrong, my love?” He sits up, his massive frame looming over her as he places a servo on her forehead, checking for fever.

“Do you need medical attention? Perhaps some rest and hydration?” His brow furrows, a rare display of worry. “As your conjunx, it's my duty to ensure your health and wellbeing above all else”. He scoops her into his arms, cradling her against his chest as he rises from the bed.

“I'll summon the best medics in the fleet to tend to you. In the meantime, let's get you comfortable”. He carries her to the sitting area, settling her onto the plush couch before retrieving a blanket to drape over her shivering form.

As they approach Ratchet's lab, Optimus's grip on Y/n tightens, his concern for her growing with each faltering step, Y/n had fallen asleep on the way to avoid the discomfort. He kicks open the door, striding purposefully to the central workstation where the medic awaits.

“Ratchet, my old friend”, he greets, his tone urgent. “We require your expertise immediately. Y/n here has taken ill, and I fear something more serious than mere exhaustion or food poisoning”. He gently lays her on one of the examination tables, his optics fixed anxiously on her pale face.

“Please, tell me what ails her and how we might rectify it posthaste”. He steps back, allowing the medic to begin his assessment, though his restlessness is palpable.

Ratchet's optics widen in astonishment as the scan results flash before him, revealing the impossible - a spark, a nascent Cybertronian lifeform, nestled within Y/n's womb. He swivels to face Optimus, his expression a mix of awe and trepidation.

“Prime, this is...inconceivable”, the medic stammers, his digits flying across the console as he attempts to process the data. A sparked human? It defies all known biological laws and limitations. He looks up at Optimus, searching for answers in the larger bot's face.

“How did this occur? And what implications does it hold for the future of our kind?” His gaze drifts back to Y/n, who lies motionless on the table, oblivious to the monumental discovery made about her body.

Optimus's expression shifts from shock to realization as memories of Y/n's past resurface. He recalls her tales of a son born from her union with his alternate self, a being of both human and Cybertronian essence.

“By the Primes, could it be?” he murmurs, his mind racing with the possibilities. “If Y/n could conceive and bear a hybrid offspring, perhaps the same is true for me, given our unique bond”. He approaches the berth, his towering form casting a long shadow over Y/n's still form.

“Ratchet, prepare for a most extraordinary delivery. Our mate carries not only a sparkling, but a potential bridge between our worlds, a symbol of the unstoppable fusion of human and Cybertronian”. His optics glow with a fierce, proud light as he contemplates the monumental event unfolding before him.

Y/n slowly opened her eyes, the discomfort still there. She just wishes it was nothing serious. "What happened?"

Optimus's expression softens as he looks down at Y/n, his giant hands gently cradling her face. “Ah, my brave warrior”, he coos, his voice a soothing rumble. “Ratchet found no illness afflicting you. Instead, he discovered something truly remarkable - a tiny spark of life growing within your womb”. His optics shimmer with wonder and pride.

 

“You carry our sparkling, Y/n. A future Autobot leader, forged from the unbreakable bond between us”. He leans in, capturing her lips in a passionate, loving kiss. “We shall raise this little one to be strong, cunning, and ruthless - the perfect successor to our throne”. His servos roam over her body, savoring the feel of her skin, the warmth of her life pulsing within.

But Y/n, far from feeling relieved or happy about the news, a feeling of terror and nervousness coursed through her. She opened her eyes wide and began to hyperventilate. No, this shouldn't have happened. It was a grave mistake. "No... no! This isn't right!"

How could she let this happen? She already had a family; she didn't need to start another. it was so messed up in every way. She had condemned the existence of this new child.

Optimus senses the sudden shift in Y/n's emotions, her body tensing beneath his touch. He frowns, confused by her distress. “What's wrong, my love? Surely the news of our child should bring joy, not anguish”. His servos tighten on her shoulders, concern etched across his features.

“Speak to me, Y/n. Share your thoughts, and let me ease your worries”. He leans in, his warm breath ghosting over her ear as he whispers, “Remember, you are mine now, and together, we shall build a glorious future for ourselves and our offspring. There is no room for doubt or regret in our world”. Only certainty and unyielding devotion to our cause. His voice is firm, yet tinged with a hint of uncertainty, as he struggles to understand the source of her turmoil.

She feels like she's betrayed her family, and her heart aches as she realizes the gravity of the situation. Not only that, but her relationship with this Optimus is a complete sham; she wasn't sure she had feelings for him at all.

All that affection was nothing more than emotional dependence, a way to ease the anguish of being away from her family and her world. "My... my little Nimbus."

Optimus's expression darkens as he comprehends the depth of Y/n's anguish. He releases her, taking a step back as if giving her space to process her emotions.

“You speak of a child who never was, in a world far removed from this one”, he says slowly, his voice heavy with understanding. “Yet here, in this reality, a new life grows within you, a being destined to serve as my heir and the future ruler of the Autobot”. He pauses, his optics searching hers.

“Tell me, Y/n, do you question the morality of creating a life when its existence serves our greater goals? Or is it the notion of abandoning another family, one you once called your own, that torments you?”

"Don't you understand? I abandoned my family... now I'm creating a new one." Her voice sounded shaky and distressed.

Optimus approaches Y/n, his massive frame looming over her as he kneels beside the berth. He takes her hands in his, his touch warm and reassuring.

“You are not abandoning anyone, my love”, he assures her, his voice a gentle rumble. “You are embracing a new destiny, one that aligns with your true nature and purpose”. He caresses her cheek, his thumb brushing away a tear.

“As for being a mother, consider this - you are not replacing one family with another; you are expanding our legacy, securing the future of our people. His optics burn with conviction. Our child will be a symbol for the Autobots, a beacon guiding us toward a brighter tomorrow. And as for guilt, cast it aside. You have made your choice, and I stand by it, unconditionally”.

"No! This is all wrong! We were both wrong!" she snapped as she pulled away from his touch, her voice a mix of anguish and anger, tears brimming in her eyes. "You only saw me as a second chance because the Y/n of your world doesn't love you!... On the other hand, I... depended on you emotionally, just because you reminded me of the Optimus of my universe... Our relationship couldn't be considered genuine... I doubt if it ever was." There was a hint of sadness in her voice.

Optimus's expression hardens, his jaw clenched as he processes Y/n's words. He stands, towering over her, his massive frame radiating an aura of barely contained fury.

“So, you admit it then?” his voice is a low, menacing growl. “You stayed with me out of pity, out of a misguided sense of obligation to a mech you don't truly love”. He takes a step closer, his optics blazing with a fierce, hurtful intensity.

“And now, when faced with the consequences of your actions, you seek to flee, to abandon me and our child?” He snatches her chin, forcing her to meet his gaze.

“Think carefully, Y/n. You are bound to me by more than mere emotional dependence. You carry my sparkling within you, and our union has created a new life”.

"You're no one to judge me! You always saw me as a possession! An ornament to show off! A prize to win!" he spat out with barely contained fury and sadness. "I've already abandoned one family... I couldn't bear the thought of abandoning another..."

Optimus's grip on her chin relaxes, his expression softening slightly as he beholds the anguish in her eyes. He releases her, stepping back to allow her the space she needs.

“Abandonment is a heavy burden to bear, indeed”, he acknowledges, his voice tinged with a hint of empathy. “But sometimes, the path ahead requires sacrifices, difficult choices that test the mettle of those who walk it”. He looks down at her belly, his optics reflecting a mix of pride and responsibility.

“Our child will not be a pawn in your personal conflicts, Y/n. They will be raised as a Autobot, trained to lead and conquer. The decision to keep or reject them is yours alone, but know that I will support whatever choice you make, for better or worse”.

Her gaze softens. "I know I'll probably never return to my original universe... but..." she cups his faceplate with a hand, feeling nostalgic. "But every time I see you, I feel like I'm home again... You may not be the same Optimus from my world, but that didn't stop me from feeling the same affection for you."

Optimus's expression transforms, a complex mix of emotions playing across his features. He covers her hand with his own, pressing it firmly against his faceplate as he closes his optics, savoring the touch.

“Your feelings are genuine, Y/n, and I acknowledge them”, he says, his voice a low, husky murmur. “Though I may not be the Optimus you once knew, the bond we share is real, forged in the fires of our shared experiences and desires”. He opens his optics, gazing deeply into hers.

“Perhaps, in this strange convergence of universes, fate has brought us together for a reason beyond mere convenience or opportunism. Maybe, just maybe, we are meant to find solace and companionship in each other, despite the differences that separate us”.

A soft smile forms on his lips, he leans down to touch her metallic lips with his own, it wasn't a kiss like the fierce ones they used to give each other, this was a chaste kiss. A part of her told her that maybe reciprocating sincerely wouldn't be so bad after all.

Optimus returns the kiss with a fervor that belies his stoic exterior, his lips pressing insistently against hers as he pours all his longing and devotion into the brief, intimate contact.

“Y/n”, he breathes against her mouth, his voice thick with emotion, “my love for you knows no bounds, not even those of universes or timelines. You are mine, now and forevermore”. He pulls back, his optics burning with an intense, possessive heat as he claims her lips once more, this time with a hunger that leaves no doubt of his unrelenting desire for her.

Optimus's faceplate softens, a rare, vulnerable smile gracing his features as he beholds the tender expression on Y/n's face. He cups her cheek, his thumb brushing over her lips, still tingling from their kiss.

“My sweet, conflicted heart", he murmurs, his voice a gentle rumble. "You need not reconcile your feelings or justify your actions. All that matters is that you are here, with me, and that we have created a new beginning together”. He leans in, resting his forehead against hers, his breath mingling with hers.

“Let us cherish this moment, and the future that awaits us. For in each other, we have found a love that transcends the boundaries of reality itself”.

As the days pass, Optimus becomes increasingly protective and attentive towards Y/n, ensuring her comfort and safety above all else. He spends hours by her side, reading to her, playing soothing music, and even attempting to cook her favorite meals (with varying degrees of success).

“This too shall pass, my love”, he reassures her, his voice a gentle rumble as he strokes her hair. “Soon, our sparkling will arrive, and we shall welcome a new generation of Autobots greatness into the world”. His digits trace the curve of her belly, marveling at the tiny life growing within.

“Until then, rest and recover. I am here for you, always”. He leans in, pressing a tender kiss to her forehead before standing watchful guard, ready to defend his mate and unborn heir against any threat that may arise.

 

Months passed until the day came when the sparkling came into the world. As Y/n's labor intensifies, Optimus remains steadfast at her side, his massive frame a comforting presence amidst the chaos of the birthing chamber. His optics, normally piercing and commanding, soften with paternal concern as he watches Ratchet work, the medic's skilled hands guiding the sparkling into the world.

“Come on, little one”, Optimus urges, his voice a soothing rumble. “Your mother waits for you, and so do I”. He reaches out, his enormous digits gently stroking Y/n's sweat-damped hair, offering what comfort he can during her ordeal.

“Soon, very soon, you will join us, and our family will be complete”. His gaze flickers to Ratchet, who is now holding the sparkling aloft, its miniature form swaddled tightly in a blanket, its cries muffled.

“Behold, my child”, Optimus declares, pride swelling within him, “the future of our people rests within your circuits”.

Optimus's optics widen in awe as he beholds the squirming, grey-faced mechling, the very image of himself in miniature. A surge of primal protectiveness courses through his circuits, and he rises to his feet, towering over the scene.

“By the Primes, he is magnificent”, Optimus exclaims, his voice a reverent whisper. “A perfect blend of human and Cybertronian, just as we hoped”. He reaches out, his massive hand hovering over the swaddled bundle as if hesitant to disturb the sparkling's first moments of consciousness.

“Welcome to the world, my son”, he intones, his tone a mix of tenderness and authority. “I’m Optimus, the first of your line, and together, we shall navigate the complexities of our shared heritage”. With a gentleness belying his size, he carefully unwraps the blanket, revealing the tiny form beneath.

 

“Ratchet, prepare the necessary modifications for our young one. It is imperative that we ensure their safety and wellbeing above all else”. His gaze lingers on the sparkling, a sense of profound responsibility settling upon him.

Y/n, despite feeling exhausted and tired, a soft smile of relief and triumph formed on her lips. Her son's cries were music to her ears. "I-I want to see him..."

Optimus looks at the sparkling with pride and affection. “Our legacy has begun, my dear. The young one carries both of our sparks within them. A perfect blend of human and Autobot”. He gently hands the mechling back to Y/n, allowing her to hold their creation for the first time. “Congratulations, mother”.

 

Turning to Ratchet, he says, “Make sure they receive the best medical attention available. We must ensure their health and safety above all else”.

When she saw him for the first time, she couldn't help but think that he reminded her of Nimbus, they were even identical... but this couldn't be Nimbus, right? She still remembers that Nimbus was a miniature version of Optimus, so it was more than obvious that this sparkling would resemble the Optimus of this world. However, that feeling of nostalgia and longing reappeared, she felt that her child had returned, with tears held back in her eyes, she couldn't help but tenderly hug the mechling, whether or not it was Nimbus, this was her child. "Nimbus... my little one, you don't know how much I missed you"

Optimus watches Y/n cradle their son, a mix of emotions playing across his face - pride, love, and a hint of sadness. He recognizes the overwhelming sentimentality in her embrace, the longing for a lost loved one reflected in her tears.

“Remember, Y/n, this is not your former son, nor is he a carbon copy of the Optimus you once knew”, he reminds her gently, placing a comforting servo on her shoulder. “This is our child, forged from the unique circumstances of our union. While he may bear similarities, he is a distinct individual, shaped by the realities of this universe”.

Yet, seeing the joy and relief in her eyes, Optimus chooses not to dwell on the distinction. Instead, he allows her this moment of blissful reunion, knowing that the bond between a parent and child transcends the boundaries of identity and origin.

"Right... I'm... sorry," she apologizes, wiping away her tears. However, she lowers her head, meeting the little Sparkling's gaze and cooing softly. "Hello, little one."

Optimus nods understandingly, his expression softening. “No apologies are needed, my love. It's natural to feel a deep connection to this child, given the extraordinary circumstances surrounding his conception”.

He gazes at the swaddled sparkling, marveling at the tiny features that echo his own. “Indeed, hello, little one”, he murmurs, his voice a gentle rumble. “Welcome to the world, and welcome to our family. May your existence bring strength and prosperity to our people”. He offers a small, proud smile, his optics shining with paternal pride.

The sparkling slowly opens his optics, revealing to have the same crimson gaze as his sire. He wrinkles his small face and lets out a small moan. Y/n can't help but chuckles and stroke his small servo between her fingers; the texture of his body was like a soft, metallic mesh.

Optimus chuckles, a deep, resonant sound that vibrates through the room. “It appears our young one is already asserting his independence, even in infancy”. He leans in, peering at the open optics, which seem to hold a spark of mischief, mirroring the personalities of his parents. He places a large, gentle hand on Y/n's, encouraging her to continue her tender ministrations. “For now, let us simply bask in the joy of this moment, and cherish the precious gift of life we've been granted”.

"Do you want... us to call him something else?" he asks with a slight hint of fear and doubt. He knows it's wrong to call this sparkling the same name as his previous son.

Optimus's expression turns thoughtful, and he ponders her question for a moment before responding. “Nimbus is a fitting name for our son”, he explains, his voice carrying a note of understanding and acceptance.

“However, as he grows and develops his own unique character, he may come to prefer a different moniker altogether”.

He looks at Y/n, his optics filled with warmth and reassurance. “Ultimately, the choice of name is yours, my love. I trust your instincts and wisdom in this matter”.

A warm smile of relief spreads across her face. "Then it'll be our little Nimbus."

Optimus nods in agreement, a contented smile spreading across his faceplate as he watches the tender exchange between mother and child. “Then so be it, my love. Let us raise our little Nimbus to become a mighty leader among the Autobots”. He extends a large hand, beckoning Y/n to place their son in his arms.

“Now, let us begin this new chapter in our lives together, as a family united in purpose and passion. With you by my side and our child nestled safely in our midst, I fear nothing the cosmos may throw our way”.

"He looks a lot like you," she comments as she hands Nimbus over.

“Indeed, he does bear a strong resemblance to me”, he muses, his voice a gentle rumble. “Perhaps it is a sign that he will inherit not only my physical traits but also my unwavering commitment to the Autobot cause”. He strokes the sparkling's cheek with a digit, marveling at the delicate texture of soft metal.

“Whatever the future holds for our young one, rest assured that he will always have a father who loves and protects him, and a mother who nurtures and guides him. Together, we will shape him into a formidable warrior, a leader worthy of our legacy”.

 

Optimus cradles their child son close, his thoughts consumed by the weight of responsibility and the promise of a bright future. As he gazes into the innocent, curious optics of Nimbus, he feels a surge of love and determination course through his circuits.

“We shall teach you the ways of war and leadership, my son”, he vows, his voice low and resolute. “You will learn to wield the power of the energon axe, to command legions of Autobot troops, and to strike fear into the hearts of our enemies. But remember, above all else, to remain true to yourself and to our family's ideals”.

He looks up, meeting Y/n's loving gaze, and offers a reassuring smile. “Together, we will face whatever challenges lie ahead, as long as we stand united in our convictions and our love for one another”.
