Chad wanders the hallway on the lower floor of SDN, his boyfriend always spends a bit of extra time in the workshop after second shift so that Chad can get a workout in before they go home.  It's late enough that the floors of SDN are nearly empty, only them and the janitors usually stay this late.

 

There's light coming from the door to Royd's workshop. He can hear Robert puttering around as he approaches the door, expecting him to be hunched over the desk or tinkering with the suit. Instead, he sees his boyfriend dressed in deep blue spandex, adjusting his cowl as he looks into the reflection of the glass partition with a sigh.

 

"Damn Bobert, all that padding and your ass is still flat?" Chad calls out, snickering when Robert jumps from the sudden noise. He's met with an eyeroll and a middle finger before he saunters up to his boyfriend from behind and wraps his arms around Robert's waist, smiling as he melts into Chad's arms.

 

Chad puts his chin on his boyfriend's shoulder and hums, "So what's with the sad fashion show?"

 

Robert sighs, "I'm not allowed to go on patrol until they get me my new flightsuit," he leans back into Chad's arms, "Apparently SDN wants Mecha Man to have a new look with his resurgence. Guess I just wanted to get one last look before I toss it."

 

Chad clicks his tongue, "And you didn't invite me? Very rude..."

 

He starts to feel Robert up, running his hands over the smooth material sensually. He moves his hands down to Robert's thighs, grinning at the feeling of body fat under his hands. They've only been dating for a few months, but he's making sure his man is pampered adequately at every given moment.

 

He feels Robert's shoulders move with a little laugh before he turns around in Chad's arms, pulling him down for a gentle kiss. He smiles as they separate, hands roving up and down Chad's own body before settling at his hips.

 

Robert looks back up at him hungrily, "How was your gym session?"

 

Chad grins, "Pretty basic, but I had a very nice shower afterwards."

 

"Did you now?"

 

"Mhm," he whispers, "very thorough."

 

Robert's hands squeeze his hips and he growls, "Hands on the desk, now."

 

Chad doesn't even hesitate, immediately pulling away to get his arms out of his suit without ripping off his nipple piercings and scrambling towards the nearest workshop desk. It's covered in papers and pens that be brushes to the side, leaning over the desk on his hands and whimpering as the quick movement jostles the plug in his ass. Before he knows it, there are hands on his hips, pulling his still-clothed ass back onto Robert's groin. His boyfriend nips at his neck softly, letting his bulge grind into Chad's cheek before dipping into the crack of his ass and rubbing against the base of his plug. Chad chokes and tries to grind back, but Robert's hands keep him in place as he stops his movement and gasps.

 

Robert disappears from his back for a second before the fabric of Chad's suit is pulled down to sit just under his cheeks, hands moving to spread them apart. Chad looks over his shoulder to see his boyfriend's masked face, his eyes are wide with a lustful hunger that makes Chad's stomach flutter with the knowledge that he caused it. Then suddenly, Robert drops down out of his line of sight.

 

Chad doesn't have time to even process before he feels Robert's tongue trace the base of the plug, licking around it desperately. Chad moans and closes his eyes, pushing his ass back into his boyfriend's face as his tongue travels down to lap at his balls and suck one into his mouth. One of Robert's thumbs presses against the base of the plug, moving it in gentle circles as he licks upwards and starts to press sloppy kisses to his taint. Every circular grind of the plug gives him a few seconds of reprieve between brushes to his prostate when it angles downward again, making him whine and buck into the feeling of an orgasm starting to build.

 

Before he can truly begin to chase his pleasure, the contact stops entirely. Chad whimpers and ducks his head as the hands pulling his cheeks apart leave and make his ass clap together lightly, jostling the plug too lightly to feel satisfying. A soft kiss is placed to his cheek, his hip, his lower back, and so on as Robert's lips trail upwards and return to his neck yet again.

 

He feels his boyfriend smile against his neck as a zipper pulls and fabric rustles behind him.

 

"You're so desperate," Robert whispers in his ear as gloved fingers finally find the base of the plug again, tugging on it lightly without letting it breach his rim properly.

 

He does it again, "Did even work out? Or did you spend the entire time prepping yourself?"

 

Chad whimpers and clenches around the metal as Robert lets it go again, trying to get it deeper into his ass somehow despite knowing it won't work.

 

"Answer me," Robert whispers, "did you work out?"

 

"No," Chad admits with a whimper.

 

Robert presses a kiss behind his ear, "Good boy."

 

Chad gasps as the plug is finally, slowly pulled out of him. The stretch as the wide bulb finally gets pulled from his hole is addicting, making him tense with pleasure before the thin taper finally leaves as well. He feels the tip of the plug trace light circles around his rim as Robert's head pulls away from his neck, presumably to watch him clench around nothing.

 

He hears the plug clatter against the desk and the sound of someone spitting before the blunt head of a cock is pressing against him, slowly pushing in. His boyfriend groans behind him as he takes slow, shallow thrusts in and out of his hole, going slightly deeper with each pump until he finally bottoms out and his hands come to rest next to Chad's on the desk. Soft kisses are peppered against his shoulder as Robert lets him adjust to the stretch.

 

Robert stops his kissing and instead leans forward into Chad's body, pressing the sides of their heads together and whispering into his ear gently.

 

"You're so tight for me, such a good boy..." His breath is hot against Chad's ear.

 

"All for you," Chad chokes as the head of his boyfriend's cock rubs against his prostate, "tight for you Mech— Robert."

 

His boyfriend gasps behind him, "What was that, baby?"

 

"Fucking— nothing! It was nothing, just fuck me already!" He tries to grind back into the body behind him, but gets stopped by his boyfriend's right hand pressing the small of his back between them and leaning away slightly.

 

"Is that any way to speak to a hero, Chad?"

 

Oh god, he clenches hard around the length inside him and whines. Stupid fucking detail oriented boyfriend, stupid fucking flight suit, stupid fucking history of jerking off to the idea of Mecha Man every night in prison.

 

He feels the hand on his back move to his side, the weight of another body, Mecha Man's body, lean back into him. The softness of the spandex, the gentle glide of the glove against his side, the feeling of a large 'M' pressing into his back, it all overwhelms him quicker than he'd like to admit. He feels a nibble against his earlobe and then—

 

“You want Mecha Man to breed you baby?”

 

And fuck, wouldn’t that be hot? For Robert to fuck him so hard and full that biology refuses to get in the way of claiming what’s his? He could walk out of here after this, plug shoved right back in his hole, and go home knowing Robert— no— Mecha Man stuffed him full while he was bent over a table?

 

The idea has him moaning and grinding back into Robert’s hips, “Please

 

A right hand wraps around his abdomen and pulls him up a bit more, “You want that? You want me to fill you up?”

 

Robert starts rubbing his stomach sensually as he begins shallow thrusts. A soft nip to his ear as Robert’s cock fills him repeatedly makes him whimper and clench around the length inside him. He’s scared to look down and accept that there won’t be a bulge protruding from his pelvis when he opens his eyes.

 

Robert’s hand presses firm into his stomach and he whispers again, “You’d look so pretty carrying my kid, it’d be obvious the moment you start to show too. Your suit doesn’t hide anything, everyone would know you got knocked up before you could even think to hide it.”

 

Chad whimpers again and tries to press into the hand, but Robert’s already moving it up to his pec and squeezing.

 

“Your tits would get even bigger, I bet they would fall right out of your suit on missions. It would be such a scandal when you nip slip and,” a tug on the barbell of his right nipple makes him choke, “everyone sees these pretty things. What would the press ask?”

 

Robert kisses at his neck again, beginning to suck a hickey right underneath his jaw.

 

He chokes at the idea of Robert marking him up, “Rob—“

 

“Wrong name, gorgeous.”

 

Smug bastard.

 

Mecha Man,” he whimpers, “you’re going to bruise it—“

 

Robert unlatches from his neck, “Good. Don’t you want everybody to know who knocked you up?” He licks over the forming hickey and moves his hand back down to the desk to grab Chad’s right hand and bring it down to his abdomen while using his other hand to begin jerking Chad off. His hips begin to pick up rhythm again as he holds Chad’s amputated hand to his womb, “I want you to feel me knock you up, can you be a good boy for me?”

 

Chad whimpers and nods as something wet begins to run down his face, he sniffles and chokes on a sob. Robert’s right hand moves to his cheek and wipes a tear with his index finger, slipping it down into Chad’s mouth to lick it clean.

 

He kisses the nape of Chad’s neck with a sigh, “I know gorgeous, it’s so hard with your womb so empty, isn’t it?”

 

Chad nods and whimpers around Robert’s finger, it is hard. He hates feeling so barren, so incomplete.

 

“Just a little longer,” Robert’s hips speed up, “you’re doing so good for me,” his hand begins to speed up as well, thumbing the head of his cock with every few strokes and using his pre-cum to jerk Chad off even faster.

 

“Just be a good boy and come for me, let me feel you come on my cock.” Robert whispers into his ear gently, even with the rough pace of his hips.

 

It only takes a few more thrusts before Chad is coming all over the desk, come splattering all over the table as he whimpers around Mecha Man’s finger.

 

“Good boy, so beautiful for me…”

 

Robert’s come-covered hand leaves his cock, pressing his left over Chad’s right against his abdomen as he starts to chase his pleasure in earnest. Chad’s hole feels raw but he doesn’t care, he needs Mecha Man to come, he needs it, he needs to be bred he needs Mecha Man to get him pregn—

 

A loud moan graces his ear and he finally feels a sticky load of come shoot into him as Mecha Man’s hips stop thrusting and just grind into him. He can feel spurt after spurt fill him again and again, pouring into all the cracks of his soul and fixing him. He’s going to be pregnant and swollen and everyone is going to know how because he’s going to show off whenever he gets the chance that Mecha Man knocked him up.

 

His arm shakes where it’s holding him up against the table, he’s not sure he can keep upright much lo—

 

“It’s okay, I’ve got you Chad…”

 

He feels the finger leave his mouth and wrap around his abdomen, leaning him forward to rest his head and shoulders onto the wood of the table. Kisses get peppered across his neck and shoulders as soft praises get whispered and his left thigh gets massaged gently by a sticky, gloved hand. He chokes on another sob and feels his stomach rise and fall underneath his right hand, smiling through tears at the slightly bloated feeling in his gut where he knows Robert’s come is taking.

 

Robert smiles too, lips pressed right against his shoulder blade as he starts to talk again.

 

“You did so good, I’m gonna pull out and get a towel okay?”

 

Chad whimpers and shakes his head, if Robert pulls out his come will too and then it won’t work and Robert won’t want him anymore. If it doesn’t take then he’s gonna leave and Chad will be alone again. Nobody else will ever want to knock him up, nobody else would ever want to show him off, nobody else will ever want to make him theirs

 

“Woah, woah, calm down,” Robert’s hand starts to move in circles against his stomach again as he presses a kiss to Chad’s hair, “I’m not gonna leave you baby, I’ll put the plug right back in after I pull out okay? Is that alright with you gorgeous?”

 

"M'kay..."

 

Robert moves his gloved hands to his waist, rubbing up and down to soothe him before trailing down his sides to his ass. He feels the large 'M' shaped emblem lying against his back leave as hands dip between his crack and spread his cheeks apart.

 

Robert lets out a soft sigh, "Fuck you look so good like this," a thumb prods at his inflammed rim, "all raw like a good toy."

 

He whimpers as Robert's cock starts to slip out slowly, the shaft rubbing against his rim as it slowly slips out. When the head finally pops out, he feels the soft pad of Robert's thumb press against his hole as the other hand leaves him completely. Something to his left clatters and he hears Robert spit before the thumb against his hole is replaced with the wet tip of a plug pushing in slowly. He gasps as he feels it finally pop into his hole, clenching against it just to be sure that it stays in him, that Robert stays in him.

 

"There we go," Robert coos, "nice and full, good boy."

 

He feels Robert step away and hears the rolling of a desk chair before pleather hits the back of his knees and he crumples, pillowing his head into his arms as he falls into the chair. The plug inside him shifts as he hits the seat of the chair, rubbing against his prostate painfully.

 

"There we go," Robert's hand comes to rub his lower back, "just relax and let it take, I'll grab us some towels from the locker room."

 

Soft lips press to the top of his head and he cant help but turn his head to look up at Robert. His Mecha Man mask is still on, smiling softly despite looking just as wrecked as Chad feels. He brings his hand up and smooths Chad's hair so gently that Chad can't help the whimper that he lets out.

 

Robert's smile softens, "You did so good, I think you deserve a reward."

 

His hand trails down to Chad's jaw and tilts it up before leaning down to press a soft kiss to his lips. Chad relaxes in it, knowing Robert will keep him upright. Robert smiles against his lips and pulls away, guiding him to lay his head back down. Chad sighs into his own arms and relaxes as Robert's hand rubs his shoulder blades in soft circles as he whispers, "Why don't you take a quick nap while I clean up, I'll wake you up when it's time to go home."

 

Chad sighs, that sounds nice...

 

Robert laughs, "Get some rest, baby."

 

Chad decides to be a good boy and listen, letting the soft hand rubbing against his back lull him to sleep.

 

 

 

 

 

 

 

 

 

 

 

Notes:

Ugh okay i need to rant about this for a second. Dont get me wrong as a trans guy who reads trans guy breeding kink fics i fw it hard but oh my god there is something so sexy to me about a person getting anally penetrated and slipping into subspace and genuinely thinking theyre gonna get knocked up. I couldnt bring myself to write an aftermath of him finally dropping and realizing he wasnt actually pregnant but idk if the people want it i can make a part two angst but i genuinely find cis characters experiencing non traditional gender dysphoria so interesting. Like flambae ofc knows he doesnt have a womb and cant bear children but can you imagine him dropping and sitting in the bath with robert and just crying at the realization that he cant carry his own child? Not that i think he would ever devalue having a non bio kid or anything but i know for a lot of people the experience of having a child in their own womb and carrying it to term and putting in the time and experience can be so important to them.

Idk im the opposite id rather die than get pregnant (genuinely id probably end up killing myself in the attempt to induce miscarriage) because to me its parasitic and disgusting to think of in my own body. But like im so curious about hlw it may be for a person who does want that but cant have it and is also comfortably a man. Idk maybe im overthinking it hope you guys enjoyed the porn i had fun writing it.
