Rodimus denies it every time, but he's a heavy sleeper. He snores like a congested rhino; he constantly sets twelve alarms that only barely stir him from his slumber. Despite being captain of the ship, his sleep schedule is far from tip-top shape.
And no, you're not a stalker. You're just Rodimus' observant little 'pet' human, always there, with a California king on his bedside dresser. Yeah, you're treated like royalty by an incredibly hard-to-deny hot alien robot.
So, as the ship ventured further into deep space and the nights got colder, you whined and begged to stay with him.
Rodimus was very hesitant to let you join him in the berth. As much as he cared about you and would kill an army for you, he didn't want to accidentally kill you, which was very much a possibility in any scenario on this ship. But he caved. You had mastered the sad, wet cat look, and Rodimus had the willpower of a rock.
Relishing in victory, you're curled up comfortably against Rodimus' lower plating for the third consecutive night in a row, warmed by the large servo of a sleeping giant. The entire palm of his hand covers your back in subconscious protection, and every so often, you feel a twitch of one digit. It's tranquility and a rare comfort, the touch of another you haven't felt since being on earth.
Until he rolls over.
Rodimus, choking on his snores, flips over onto his stomach and nearly tosses you off the berth if not for the grip he has on you. Despite almost winding you and making an audible 'Oof' sound, he doesn't wake up, his unconscious body assuming another comfortable position.
It takes you a few moments to register what the fuck just happened, but you realise that you're now underneath Rodimus. Almost his entire body weight is now pressed against you and pins you to the berth.
Oh god, you think to yourself.
This is less than ideal; this was not supposed to happen. How the hell are you, a tiny ass human, supposed to get out from under him? You probably shouldn't even be alive right now with how restricted your breathing is, not to mention how hard he flopped on top of you. But thankfully, with how Rodimus' legs have fallen into position, it leaves you with just enough room for your chest to rise and fall.
"God." You whine, muffled as your cheeks squish against his abdominal plating.
Your mind runs wild as you try to think of a way out. Maybe he'll just roll over again soon? God, you hope so; you can handle only so much weight, and Rodimus feels like he could hold down a cargo ship. Probably because he can.
But until then, however long that may be, you need to try something at least.
"Rodimus?" You try to wiggle but to no avail. He has you pinned pinned, and you use what little breath you have to yell out to him, "Hello? Are you awake or what?"
A loud, seemingly exaggerated snore replies to you. He's still deep in recharge, ruining any chance you have of waking him up yourself. You try to use your nails to scratch the surface of his frame, hoping it would tickle him or something, but that doesn't work either.
"Great." You roll your eyes, only you would ever end up in this type of situation. If only you had listened to Rodimus when he first said no, then you wouldn't be currently experiencing a near death experi-
"Y/n..." Rodimus' hoarse voice crackles above you, sending vibrations through your bones.
"Oh, thank god," You sigh in relief. You attempt to wiggle around some more, hoping to get his attention this time, "Listen, can you get off me now? This kinda hur-"
You squeak softly in pain as his sharp pelvis presses against you, and you hear your name again. This time, though, the tone of his voice came out as a whine, like a soft plea.
Because of where you were positioned before you became a pea under a princess' tower of mattresses, Rodimus' lower panels rested right against your stomach. This means you can feel his panels start to bulge slightly.
Oh no, you think to yourself bleakly once again. You're not sure how similar Cybertronian anatomy is to humans, apart from a crude explanation by an engex drunk Swerve. Still, it doesn't take a genius to figure out that you're feeling him getting hard. Putting two-and-two together using two out of the five senses, you've realised that Rodimus is nearly boner deep in a wet dream.
And not to assume, but you're thinking that the star of the show is you.
It's also the wrong time to cackle to yourself about getting crushed by your crush.
You might have some issues to work out after with Rung.
"Oh fuck," You reasonably panic, trying to push against his heavy frame weakly with your pinned arms, "Oh fuck fuck fuck fuck-"
You start to thrash against Rodimus when your arms fail, your tiny body rubbing up against him. This doesn't help at all, you've come to realise but actually digs you in a deeper hole as he begins to rock his pelvis into you.
Rodimus moans your name again as he sleepily grinds against you. Whatever he's dreaming of, it must be an insanely hot pornographic fantasy of you. The bulge grows bigger, pining you down further into the berth. He shutters and lets out a soft groan before his plating shifts, and you feel a very thick, very hard, and very hot object slide up against you.
Oh god, it's his dick.
Swerve might not have told you all the details, but he seemed to conveniently leave out how fucking huge Cybertronian cocks are.
As if you thought this couldn't get any more debilitating, you now have the head of Rodimus' spike pressing against your face. It's as if the Alaskan bull worm had slithered up between yourself and Rodimus to give you a kiss. The behemoth of baggage has already started leaking what you would believe would be the Cybertronian equivalent to pre-cum, smearing all across your face.
At this significant turn of events, you've realised you have come to a crossroads.
Either struggle and continue to wiggle and wrangle your way out from under him, but risk pleasuring him, whether or not he could feel you squirming against him anyway with how small you are compared to it. Or, the more realistic and obtainable outcome, lie still and take it until he wakes up from an orgasm.
Who are you kidding? You don't have much of a choice at all. Both options risk you drowning in alien robot cum. It's wishful thinking as Rodimus starts to rut against your entire body again.
"Y/n..." He whimpers again, though very garbled and unintelligible. Every roll of his hips causes more pre-cum to dribble against your face and down your chest, and with each, it spreads all around in between yourself and his train-sized spike. Making an absolute mess of you.
If you weren't getting humped up against right now, you would indeed find a way to kill him for ruining your only set of pajamas.
"Rodimus-" You gag as a spurt of pre-cum falls into your mouth, "Guh- Rodimus stop-"
His work of venting increases, and so does his rutting. The comatose mech gasps and hitches his breath, oblivious to your cries and pleas for him to stop. He pushes up against you in heated desperation, fucking into your soft body like a grind pad.
"Rodimus! Wake the fuck up!" You start to heat up yourself; the increased pressure and friction of his plating will give you a fucked up version of carpet burn if he doesn't wake up. Sweat drips from your skin, adding even more lubricant to his incessant grinding.
"Wha- Oh, Primus!" Rodimus rears his drool-covered helm and cries out in equal confusion and unrestrained pleasure. He's woken up by his overload as he shoots his load up against you, flooding the minimal empty space left between you both with hot transfluid.
"Oh god-" You couldn't close your mouth in time when a spurt of transfluid hit you in the face, causing you to cough and spit it back out, only for more to splat you in the face.
Rodimus moans tiredly, shuttering violently as his spike pulses and leaks the remainder of his overload against the berth.
Or what he thought was the berth. Since when did he use a self-service mod on his spike? Especially when he shares a room with-
"Hey!" Cough, "Are you done?"
His optics slam open in horrific realisation.
"Oh no," Rodimus rolls over onto his back, his softened wet spike flopping against his abdominal plating, "Oh no, no, no..."
He looks down where he once lay, and his face plates flush a bright blue. Laying in a puddle of his transfluids was you, his little human, sopping wet with a highly unimpressed look on your tiny face.
"Oh Primus, Y/n," Rodimus scoops you up in his servos, gently tossing you from hand to hand as he wrings them off his transfluids, "I am so sorry, I- frag what was I thinking!" Rodimus babbles and holds you to his face, "Are you okay? God, I'm so stupid-"
"Ughh," You lay limply in his palm, exhausted and out of breath, "After that... I don't know anymore."
Rodimus hides his blush with a servo before pinching the bridge of his nose, "I'm glad you're okay, but what were you doing down there?"
"Great question," You lift your head up to deadpan him, then eventually drag yourself to sit up. Sticky, pink transfluid drips down your body. Your face, and hair, are all drenched in him, "It's not like you rolled over in your sleep and had me pinned for nearly half an hour. What the hell?"
Rodimus blinks, and his face turns a deeper shade of blue as he rubs the back of his neck, "Oh, so that's why I had that dream about you..."
Is he serious right now?
"Oh, you think?" You wipe your lip when it starts to drip into your mouth, "I think I could tell when you started moaning my name in your sleep."
"Well, you're just so tiny and soft and-" The red and yellow mech bites the knuckles of the servo not holding you in embarrassment. "But what was I supposed to do, huh? Hold it in?"
God, he is.
"I'm literally gonna kill you, Rodimus." You shiver, his transfluids cooling against your skin. You can't believe he dares to look you in the eye, "I am never begging to nap with you ever again, or maybe at least warn me next time."
"No offense taken," Rodimus nods in agreement for once, watching you wring your hair out, "I'm sorry, Y/n, I really am. I can help clean you up? As a sincere apology from yours truly?"
"As long as I don't come into contact with more of this stuff," You flick a bead of transfluid off your finger into his direction, "And you better be sorry, or it'll be a long time before I might actually let you fuck me."
"Wait, you'll what-" Splat, "EWUGH!!"
