Steed cracks open another Quantum and chuckles, letting his lightly-bloated gut burble as he stares you down. You had heard about his stash and wanted to nab a couple of the glowing blue colas for yourself, but the oversized man had been right there to catch you. Nude, save for the gauntlets be helmet of a T-45. No frame, no servos, just enough strength to support something that would crush a normal man.
If that wasn’t enough, he’s built like an iron foundry and tall enough to get a good view of your haircut.
“So, yooourrrp... you think you can just walk in here and take what you like?” He swigs the radioactive cola through his helmet again, somehow avoiding the filter’s water-stopping materials. You can hear bubbles forming, but it’s not clear if that’s coming from inside the bottle, or inside his stomach. “...fucking thieves.”
The giant of a man had only been in town for a few days, having brought another load of pre-war treasure and pristine Nuka-Cola Quantum cases back with him. The valuables went to the town in exchange for a room and enough food to burst a Brahmin's stomach, but the Quantum had stayed with him, despite a few requests to buy at least a single bottle.
So, like an idiot, you had decided to steal some yourself. Now you were faced with his slightly-glowing middle, which was already groaning like an attack dog that had tracked down its target.
With a light slosh from his gut, Steed presses one thick hand against the wall behind you, looming over you as his helmet filters each and every breath. "S'why you're here, right? This?" His hand gently pats the stretched belly, and you can see the blue shine of the Quantum's isotope ingredients within.
"I wasn't-"
With a heavy step forward, Steed pins you against the solid wall it his soda-bloated gut. It's like being squished by a taut drum, and you can practically hear the fuzzing sound of his bubbling insides. After a second to suck in some air, he lets loose a thick, lazy belch right above your head, one that trails off into a grunted sound of satisfaction warped by the helmet's filters. Steed's hand slips down to his side, massaging the smooth and stretched surface. "Only thing that upsets me more than a thief is aaaAAUUURP... 'scuse me, a liar. You wanted the Quantum."
You can't really deny the obvious. Practically everybody in town had been thinking of doing the same thing, but you were the first one brave - or careless - enough to try. His gut presses against you as it gives off a full groan, and you wonder just how many bottles he's already had. Snorting, Steed stares down at you, his expression hidden by the T-45 helmet. "You're not getting a drop of it. In fact, fuck it, you're gonna help me take care of mys..." he pauses to let hurt put some of the carbonated bubbles. "...nh... myself."
Within that churning and burbling stomach, you hear the deep groans of countless Quantum bottles compressed within a small space, all fighting to release their carbonation at the same time. There's no possible way that the man could fit any more inside him - he already looks like he would burst if you so much as poked him. You groan and try to shove his heavy gut away, but he just rams it forwards in response, pressing you against the wall with even more weight behind him. The impact upsets something in his body, and an unwanted rumble makes itself known before he expels another burst of gas from his mouth, sighing in relief as it fades.
"I said, you're gonna help, you little shiiiRRRRPP." This time, he accidentally manages to belch right in your face, the push so powerful that it upsets your ragged haircut and triggers the Geiger counter around your neck. It dawns on you that Quantum is very irradiated, and with how much this monster of a man had packed into his swollen middle, it's a wonder that he's still standing. You're also surprised by how quickly your cock has started to harden from something so unexpected.
You try to ask him what he means, ignoring the heat building in your loins. Pushed into his gut, you can hear every creak and whine as it struggles to hold the payload, but he still takes another swig for good measure. Almost instantly, his stomach gives off a strained moan in protest at the added pressure.
“Hff... you see, your big friend Steed’s got a problem.” With his free hand, he grabs your head and pushes your ear against the surface of his gut, making the unstoppable purrs and roars within much more clear. “Hear that?”
You nod, failing to hide your flushed face.
“Good. That is a fuckload of Quantum. Problem is... BUOOORPPPPPppp... is that a fuckload of Quantum means a fuckload of energy. Can’t go anywhere to use it up like this. See the issue?"
You know what he’s implying, and it scares you as much as it arouses you. You've never been with somebody this large before, both in terms of raw size and the overall distension of his stomach. Considering that you were trying to loot his Quantum stash, you aren't really in a position where you can protest, but your libido likely wouldn't let you anyway. It's so rare to find men this meaty in the wasteland, especially one who can drink himself into a bloated, stretched water-tank of a man that still has room for more. Even with your face smushed against the taut and grumbling surface, you can see the harsh curve of his midsection, the sign of somebody who has pushed themselves beyond comfortable limits.
After a moment's hesitation, you sigh, letting one of your hands rest on the surface of this belly. You can't deny that you'd worship a gut like this, if it came to it. "...what do you need me to do?"
"Simple, really. Man gets horny, out in the wastes. You're a man, I'm a man, we're probably both horny fucks. Get me off and I'll let you leave with your skull in one piece."
You can't tell if he's joking through that helmet, but you'd rather not find out. He isn't wrong, either - life in the wastes has had you jacking it to some of the weirdest material you can find, including the pinups in some old gun mags from before the war. No matter who's taking who, a decent cock goes a long way, and Steed isn't hiding the one he has to offer.
A weak "yes" and a small nod are all he needs to confirm that you're up for it, and with one hand, he grabs you and practically throws you into the apartment's main room, following you over to the bed with his hands cradling his moaning, groaning gut. Prep work is a blur, with Steed grabbing lubricant and getting you comfortable on the bed despite his swollen self. The blue glow of his bloated stomach is far more appealing than you expected, and before long, your cock is free from your clothing and as stiff as it could possibly be. Steed's has followed suit, the same Quantum tint lingering in his nuts as he moves himself around to the bed properly.
From up above, Steed leers down at you, positioning himself between your legs with a quiet huff. His hands move up your thighs to find purchase on your hips, holding your squirming body steady while he takes in your exposed skin. Now that he's at full mast, you can see exactly what you're working with - his cock is easily the size of a Quantum bottle itself, with a thickness that easily outmatches your own. Sitting below are two big, slightly blue-tinted balls, which must have been irradiated from constant Quantum exposure. While you know it should worry you, the idea of his radioactive semen pouring into your body and twisting your insides is too hot to pass up, despite the sheer insanity of wanting such a thing.
"I'm ready" you mutter, passing up one of the Quantum bottles from next to you. Steed takes the soda and pops the cap off with one hand, allowing a little blue fizz to escape into the air, and chuckles to himself.
With his other hand, he lines your hips up against his cock, experimentally prodding at your body to try and find the perfect angle. You don't know what'll happen when he shoves it into you - for all you know, it's irradiated too. Even if it's not, your body probably isn't cut out for this kind of thing, but fuck it, you might never get this chance again.
The first thrust is the hardest, and you feel your entire body have to stretch slightly to take the thick head and shaft properly. It's a slow movement, one that lets Steed savour every part of your inside space as he gulps down the bottle of Quantum like his life depends on it. You can hear the hefty swallows and deep, angry groans as his stomach continues to take on more than it can handle, demanding that he stops feeding it more of the radioactive soda.
You barely have time to get used to the feeling of his cock inside you before it's pulled away. Steed pauses for a moment, then bored it back into your body, tearing past your sensitive skin and demanding more space than you have available. With a whined cry of surprise, you tilt your head back and feel your hips buck under the force of his motions, only for Steed to continue the thrusts into your core. As if the pumps themselves weren't enough, his strong hand makes it easy for him to pull you down onto his member as the same time, even though only half of it is actually entering your body.
With each new push, he gulps down another mouthful of the glowing cola, his stomach swelling ever so slightly with each hefty swallow. You can see the blue flaring up inside him, his hip movements shaking up the contents and bringing the fizz to an audible level within his stomach walls. As soon as he downs the last mouthful of the drink, he throws back his head and belches loudly through the helmet filters, not even slowing down for a second while his cock nudges deeper and deeper into you.
"Hm, fuck. You're into this, huh?" he murmurs, reaching for another of the bottles near him as his stomach sloshes and groans with the constant back-and-forth thrusts. "Never thought I'd meet somebody who wants to be... uuurp... fucked by a guy with his guts full of Nuka."
His globular belly heaves and churns with the amount that's been packed into it, and you can practically see the glow rising and falling with his breathing, like his stomach is starting to reach a limit it wasn't expecting. Even so, he manages to keep his cock buried in your guts without issue, pushing in a little more of the shaft each time and opening you up to faster movements as his hips begin to press against yours. All the while, you can still hear the fizzing and burbling of a stomach that's desperately trying to contain the fizzing pool that Steed somehow forced inside it. With a sighed burp, he lifts another of the Quantums to his filter and starts to chug it down just as fast, somehow still able to hold more.
You're struggling against the way that he's digging into you, filling your entire hole and forcing your muscles to try and clench just to keep themselves stable. Your brain briefly wonders what it would be like if he wasn't laden down with all of that Quantum sloshing away inside him, but your thoughts get cut off as he manages to squeeze the last inch or so of his cock into your body.
The moment Steed's hips impact yours, you feel a spike through your spine as his cock begins to hit nerves that you had forgotten existed. Your body tries to press against it, refusing it access on an instinctive level, but you let out a long groan of pleasure as he hits just the right spot to blank out your brain for a moment. He's far larger than you had expected, like he's managing to push into your guts and open up your insides with even simple movements.
You can feel your hands tighten on the bedsheet as his stomach heaves, straining to expand even further now that he's going far beyond the reasonable limits of a normal human body. Each breath makes his entire belly bulge, like the gas inside isn't sure where to go and can't escape properly. He's so full that it doesn't even look real, but the Quantum keeps coming, each swallow making the blue grow intensify as his stomach fails to contain the radioactive light.
Steed curses under his breath and downs the last of that bottle, his cock pressing the attack faster and faster with each thrust as he builds up a strong rhythm. Each gurgle and whine from his belly only makes the following belches and verbal groans stronger as his movements continue to stir up the Quantum inside him, sloshing the isotope-laced drink around to fizz up and bubble relentlessly.
Your own body starts to let out small huffs and cries of pleasure as it finally catches up to what's happening, the obvious heft and swell of Steed's stomach amplifying the way that he's hollowing you out. You can't help but vaguely mutter out his name as you try to get proper control of your thoughts, but it's not doing much, not like this.
Tossing the bottle away and letting out a heavy belch with no attempt to hide it, Steed uses both free hands to grip your waist as he slams into you harder and harder, bending forward slightly so that you can see just how far his stomach has had to bloat to contain his liquid gluttony. If you could reach it, you would be gripping your hands all over that globular tummy, but you're stuck at his waist, feeling his cock twitch every time it manages to make room inside you.
After a couple of hearty groans, Steed's voice perks up behind his filter, and he tried to speak without much breath in his lungs. "Fuck... gonna cum if you're not caref... ful..."
Every time his balls press against you, you feel a strange heat, likely from the Quantum glow. You're terrified to think of what'll happen when he finished, but a perverted part of your brain wants him to fill you with the irradiated semen he's holding, even if it's extremely dangerous. You don't know why, but the urge is there, and each awkward thrust with his bloated middle only makes it stronger.
When Steed's hips finally shoot forward and plant themselves against yours, you realise what's happening just a little too late to rethink the situation. A heavy spurt of seed fires off inside you, and you watch the bloated man's balls tighten as they empty themselves into your body, the blue glow rapidly vanishing with each extra string he fires. At first, it all feels normal, but then you realise that he's not done when he should have been.
In fact, you're far too full. You can't tell how he's doing this, but presumably, your intestines are being slicked with a constant flood of whatever mutated contents his balls have been holding for god knows how long. Steed doesn't seem like a man who'd waste his energy on just his right hand.
Slowly, you feel your own abdomen swell slightly as Steed's thick shaft blocks the cum inside your body, forcing it into whatever space it can find. At first, you just feel a bit heavy, but then your flat stomach begins to round a little as more and more of the semen in pumped into your body. It's like being bloated from the rear, and your hand moves down to your lower stomach as you feel that your skin is firm with the dense semen coating the inside. Burst by burst, you watch the same blue glow manifest itself under your skin as your body stretches to hold it all.
It would be absurd if you weren't forced through every pleasurable twitch that Steed's member makes, refusing to give any extra room to your body while he continues to fire more and more of his cum through you. Within what feels like mere seconds, you already look at least four months pregnant, if not more. It hurts slightly, sure, but there's something about it that stokes the flames of your
The primal, lustful noises coming from the other man's mouth are only outdone by the constant fizzing and frothing of his stomach, which could easily be at bursting point if he wasn't already somehow far past it.
With a few final rough pushes, Steed groans as the last of his semen threatens to burst you open right then and there, your stomach almost hurting from how badly you've been filled. When he finally gets his composure back and pulls his cock free from you, the remains of what's been packed into your rear slowly start to even out, dripping to the floor like a thick glowing cream. Even so, you're obviously carrying far more of the luminous semen than you expected, and your middle doesn't look any less bloated.
"Heh, look at that. Nice." Steed's hand comes down on your swollen middle, and he strokes the surface. "Let's hope my little guys didn't mutate and find a way to impregnate a guy, or you'll have a hell of a nine months."
The thought makes you blush - probably just the high that you're riding - but you're truly flustered when Steed starts to crawl on the bed with you, his bubbling stomach hanging down and swaying gently as belched breaths slip out of him. You're about to ask him what he's doing, but then your eyes notice that you're still rock-hard down there.
"I said I'd let you go after a good fuck, but I can't let you walk away with this, now, can I?" You expect his hand to come down and take hold of your shaft, but instead, he lowers his bloated gut against it, pressing your cock down against your own distended tum. "Come on, you freak, sit back and I'll finish you off."
You aren't sure what he's doing at first, but after a couple of motions, your sensitive stomach skin tells you that he's gently rubbing his own gut back and forth. Another filtered belch leaves his helmet as he presses the taut flesh of his gut down on your cock, pushing it even further against your own skin while he uses his hips to sway his body up and down. Steed is literally jacking you off with nothing but the surface of his glowing, Quantum-packed belly, and the moment you understand that, it's like somebody doubled your sex drive. You start instinctively moving your hips to counter his motions as the remaining cum slowly pours out between your legs, moving a little faster every time his gut pushes down on your own.
The constant twitches and shivers of your cock are nothing compared to the way that his stomach tries to conform around it, but fails as the liquid inside sloshes and fizzes inside the rounded shape that presumably used to be a set of abs. It's not just that, but the fact that you can hear him panting, expelling a little of the slightly-irradiated gas until he lets loose a strong belch right into your face, one powerful to activate your Geiger counter even though it's completely off the bed. It should worry you, but all you're focused on is satisfying your irresistible urge to let loose and drain your body of the stress you've been under.
With a smirk, Steed grabs one of the Quantums, flicks the cap off, and jams the top in your mouth. Unsure what to do, you just keep swallowing, feeling the Quantum quickly slip down your throat and pool in your stomach before you can stop it. The fizzing sound and general heft is hardly as impressive as Steed's own, but under his breath, the giant man mumbles to you, admitting that you'd look 'really fucking hot' with some extra meat on that belly of yours. You would have expected to resist the idea of drinking so much, but your body just keeps going, adding an even stronger glow to your midsection as it stretches to hold the carbonated liquid safely.
You don't even realise what's happening until you're already halfway through the electrifying shock of an unexpected orgasm, days of pent-up stress from wasteland life melting away as you cum right against Steed's bloated gut and get some of the small strings on your chest thanks to the awkward angle. Your legs twitch and your arms refuse to let go of the bed, even as the bottle falls from your mouth and your own stomach groans in surprise, unsure how to handle being forced to chug so much cola. You're in such a strange state that you basically shut down, collapsing against the bed while Steed lets himself fall to your side, still cradling his stomach as the inside walls struggle to hold all of the Quantum that he had decided to indulge in.
The last thing that runs through your head before you drift off to sleep is a single sentence coming through Steed's helmet filter, breathy and slow, presumably because he's just speaking to himself before he too needs to rest.
"Cute lad, wouldn't mind doing this again."
You pass out, your head coming to rest against the grumbling, burbling orb that is Steed's belly. You don't even realise that you're smushing your face into the side, but he does, and it makes the big guy chuckle. Whatever he has planned for you when you both wake up, you’ll just have to see when morning comes.
