Thor woke disoriented. He was splayed out on the floor of a room, bare back pressed against cool stone, stripped half-naked. He'd been tossed there, he remembered dimly. He wasn't sure where he was in space and time: what was the last thing that'd happened?
The buzz on his neck brought him back to the current moment. Hulk. Gladiator battle. Lightning. He jerked up, swaying to his feet. And now he'd been left alone in this room, at — Thor looked out the window — high up on some enormous skyscraper of alien construction.
There was the chopping of water behind him; Thor turned. Along one edge of the room there was a hot tub — dimly lit, water softly steaming. Hulk surfaced.
Thor's muscles certainly remembered the fight, but now he felt no worse than after a sparring session. "Hulk. We good?" he said.
Water sloshed across the floor as Hulk strode out of the pool. Beads of water spilled down his green skin, making him glisten. He was... well, he was the Hulk. Physically, he was only maybe half again as tall as Thor, but he was easily three or four times wider. He was also completely naked. Thor's gaze followed the streams of water down Hulk's body; huge chest, chiseled abs, and— his eyes bulged out, staring. Hulk's cock, limp, was impossibly huge: it filled the space between his thighs and hung down nearly to his knees. His balls were just as intimidating: massive things churning in his slack sac, each one nearly as broad as Thor's entire chest; they sagged even lower. His skin there was dark emerald, duskier than the rest of his skin, and the contrast only made everything look bigger.
Hulk strode forward, and it all swayed beneath him: the side of his shaft, the flesh of his sac, they wetly crashed against his legs and stuck in place, wet, for a fraction of a moment before peeling away, letting him sway back the other way to slap side-to-side. The water streaming down Hulk's body flowed down his soft cock in a torrent, spilling past the bunched tip of his hanging foreskin to pour all over the floor.
"You, uh, have any clothes, big guy?" Thor said, holding up a hand to block his sight. "Escaping naked would attract even more attention."
Hulk huffed, rolling his shoulders, and made no move to cover himself up. "No escape. Hulk ask for lightning-man."
Thor rolled his eyes. "I know you know my name," he said, a little petulant. "We're friends!"
"Hulk ask for Thor," Hulk repeated. "Hulk win, so Hulk ask for favors."
"From who?" Thor asked.
Hulk shrugged again. "Who cares. Big guy in charge."
Thor opened his mouth to respond, but Hulk's next words left him open-mouthed:
"Hulk want to fuck! But Hulk too big," Hulk groaned, shaking his cock to prove his point. The gargantuan thing smacked against his thighs with a sound like a thunderclap. "But Thor hard to break."
Thor stared open-mouthed. He'd taken some big cocks before, but Hulk's monstrosity was on a whole other level. Hulk's cock lurched, sluggishly fattening. Its length crept down lower, past Hulk's knees. His heavy, hanging foreskin drew back, leathery flesh slowly peeling back to reveal the rich green color of his bare cockhead, wet and glistening. Hulk had a smell to him: sweat and musk and some strange chemical tang, and as he started to stiffen the reek of his revealed cockhead was ten times stronger: a scent of impossibly-virile sex, so strong it was almost acrid. Hulk's cock rippled, gnarled veins surfacing across his leathery flesh, and an enormous bead of pre seeped from his broad cockslit. It hung, glistening, from his enormous cockhead for a moment, before it crashed to the ground, splattering in the puddled water. Despite himself, Thor felt his cock start to harden too, bulging out his pants.
"You can't be serious," Thor said. "We should escape!"
Hulk just leered at him. He cupped his mammoth cock and began stroking it, letting it sluggishly harden in his loose grasp. It lurched and shuddered, pre mixing with the water still dripping off him, splattering down to the floor in a slimy mess.
Thor swallowed hard. "Oh, fuck it," he found himself saying. "We can escape after."
Hulk let out a craggy laugh. "Thor love Hulk's cock," he said. He sat back on his bed — a raised platform big enough to use as a stage — and tugged his impossibly-huge cock up, giving it a stroke, before letting it spill across his thigh — across all of his thigh, with his fattening cockhead jutting out past his knee. It visibly throbbed in time with his heartbeat, revealing a maze of veins rippling up its sides, extending further with each beat as his cock lurched fatter and fatter.
Hulk reached forward and bodily hauled Thor into his lap. His huge, blunt fingers spread between his legs, cupping his dick, and then with a single tug Hulk tore his pants apart: fingers digging into the fabric, other hand braced against Thor's bare stomach, the movement as simple as tearing apart a piece of paper. Thor's cock flopped out into the open — and Hulk's cock pressed against his back, half-hard and rising up in a heavy, drooping arch.
Thor was an Asgardian, a god, with a physique beyond anything of that of a mortal's. In his conquests across Earth, he'd found he was... considerably more endowed than anything humans had. His own cock was huge, enormous, divine — and so, so tiny compared to Hulk's. He hardened across Hulk's stomach, shaft as fat as his wrist, leaving behind slick, glistening strings of pre.
Hulk pulled his face closer, one giant finger on the underside of his jaw. They kissed: Thor's lips pressed against Hulk's lower lip, and then Hulk's tongue licked out and slathered across his entire face.
The Hulk's stumpy fingers dug into his ass, digging into the pillowy muscle, and Thor groaned and arched back, spreading himself so Hulk could dip his fingers between his cheeks, bearing down on his hole. Hulk's cock spanned behind him, hot as an iron rod, impossibly huge. A single pulse from Hulk's cock sent a waterfall of pre pouring down Thor's back, coating him in slick, stringy slime. Hulk's fingers scraped up the small of his back, collecting pre, and then he shoved a stumpy finger right against his hole, twisting and pushing to open him up. Thor groaned into Hulk's mouth, spreading himself open. Just one of Hulk's fingers was fatter than a cock, heavy and hard, crooked strangely as he worked it inside. His hand spanned up Thor's back, ladling huge globs of pre down to his ass, smearing them around his already-stretched hole.
If one finger was like a cock, two was like being double-fucked: a second fat, blunt pressure against his already-filled hole. Hulk fingerfucked him, pumping into him, and Thor found himself rutting back, groaning and shaking, his cock fully hard, leaking glossy squirts of pre all down Hulk's chiseled stomach each time his fat fingers found his prostate. The stretch of his second finger pushing into him knocked the breath from his lungs; Thor wheezed against Hulk's tongue, panting and gasping as Hulk wiggled his fingers around. Hulk spread them inside him, scissoring apart and pushing together, pinning Thor's bulging prostate between them before working them deeper. Thor writhed on Hulk's fingers, fucking himself down until he hit the knuckle.
He was dimly aware of Hulk's stubbled jaw scraping across his neck, his huge wet tongue licking out, his own hands braced against Hulk's chest, but Hulk's fingers in his ass were sending sparks of heat through his entire body: prostate burning, cock hard. Thor rode Hulk's fingers, grunting and groaning each time he bottomed out — grinding hard against Hulk's huge knuckles, eyes rolling back in his head. His cock erupted, totally untouched, dousing Hulk's chest in fat, glossy ribbons of cum, fucked out of him by Hulk's fat fingers.
Thor collapsed into his own mess against Hulk's front, body loose and lax, asshole fat and heavy. His hole throbbed with his rapid heartbeat, bruised out into a bloated swell from the spread of Hulk's two fingers. His cock kept shuddering, orgasm spilling through his whole body as he fucked his cock against Hulk's stomach, sending runnels of cum oozing through the grooves of Hulk's abs, spilling down his sides in slimy cords.
Hulk's third finger dug into the swollen rim of his ass. Thor bellowed as Hulk bodily peeled him open, hole stretched open into an enormous, pouting gape. Hulk's thumb scraped across Thor's asscheek, socketing against the open hollow of his spread hole. Hulk used his other fingers to catch the streamers of pre drizzling down Thor's back, over his muscled ass, and direct them into his spread hole. Pre gurgled as it spilled directly into Thor's open gape, and Hulk finger-fucked the sloppy mess deeper into him, smearing his thick, rich pre across his inner walls until he was slick and heavy, gape sloppy and dripping, inner flesh glazed and glistening with Hulk's pre.
Thor shuddered, clenching and releasing his ass, muscles no match for Hulk's sheer power. He pushed out, letting Hulk stretch him wider, and his eyes rolled back in his head as his hole spilled out over itself, internal flesh folding over Hulk's fingertips. Hulk crooned, twisting his hand, and sent his fingers scraping across the inner walls of Thor's ass. He sunk three fingers into Thor, the stretch like nothing else he'd ever done before. Three of Hulk's fingers was impossible, indescribable, something so huge and fat it felt like he was being torn apart, folded inside-out. Thor's entire body shuddered; he panted hoarsely against Hulk's throat, gasping for breath as Hulk methodically worked him open: fingers twisting, pushing, pulling, hooking on the bruised rim of his ass to stretch him open even wider.
Thor sobbed, howling, when Hulk shoved in deep. Knuckles bashed against his plush asslips, hot knobs of pressure when Hulk twisted his hand, digging deeply into the puffy flesh of his aching rim. His cock, half-hard, erupted without warning as Hulk finger-fucked another load out of him: this one brutal, rough, a full-body sensation that burnt through him and left him dazed and exhausted, cock pouring out its load into the slimy mess he'd already shot across Hulk's chest.
When Hulk pulled free, Thor's hole was a wreck: the broken bulk of his hole bulged out in a fat crater-rim mound, so wide they spread his cheeks in a crescent around its pulsing mound. Slowly, sluggishly, his open hole collapsed in on itself, opposite edges meeting with a wet slurp and sealing shut, squeezing his bruised asslips out into a pair of huge, plush lips. Hulk let out a laugh, pushing his fingers back inside, and Thor's freshly-broken hole immediately spread wide again, easily stretching to take his fingers. Thor groaned, his internal muscles shuddering and flexing, pushing and pulling, and Hulk groaned too, bass rumble vibrating through Thor's entire body. He finger-fucked Thor for a moment, letting his ass grip and clench around his fingers. Hulk's cock throbbed, slapping up against Thor's back, drenching him entirely with the next burst of pre. Hulk was thinking about how Thor would feel around his cock.
Thor was too. When he sat back, Hulk's fully-erect shaft throbbed behind him, bearing down against his shoulders. The thing was a behemoth. Its head was just as big as his head: Thor turned to look, twisting around to sling one arm over Hulk's cock and press it against his chest. Fully hard, it was nearly the size of Thor's entire body. He had a blunt, punishing cockhead that fanned out into an enormously-thick ridge, flesh a deep green. The ridge itself was thickly coated in glistening papules, bulging half-domes clustered against each other, shrinking down along the underside of his rim into rubbery dots. Hulk's heavy foreskin clung to his cockhead, piled up in pillowy folds against the underside. Thor reached out with both hands — the both of them not even encircling Hulk's cockhead halfway — and stroked his flesh, fingers digging into his slimy foreskin, feeling the taut dome of his bare cockhead. His cockslit was an open and dribbling mouth: cocklips two huge rumpled mounds framing the long open slash, a dark green-purple. They looked like fat lips, pursing together and flexing apart as his dick drooled out slimy cords of pre.
Thor was dazed just looking at it. He leaned in, pressing his lips to Hulk's cockslit, moaning open-mouthed as a single twitch of Hulk's dick filled his mouth to overflowing with his rich, potent pre. Thor gurgled, excess spraying past his lips, drooling into his beard. He swallowed heavily, pre burning all the way down his throat and leaving behind a greasy film coating his mouth and throat. "Hulk," he groaned, spraying excess pre all across Hulk's gleaming cockhead. "Fuck me."
Hulk let out a booming laugh. "Thor open for Hulk's cock," Hulk said, grinning, and twisted his fingers where they were resting inside of Thor's worked-open gape: pushing deeper, corkscrewing inside him, spreading his asshole into an enormous sloppy opening. "Hulk fuck him open wider." He idly finger-fucked Thor's gape as he repositioned him: Hulk held Thor's entire weight on the palm of his hand, three fingers sunk deep into his wrecked ass, and moved him around like a doll. Hulk hauled Thor up and pushed his huge blunt cockhead between Thor's legs, socketing his cockhead against the unfurled muscle of Thor's gaping ass. Thor groaned, already exhausted, legs limply twitching as he tried to brace them against anything. Hulk's fingers slipped from his ass to let his cockhead sink in fractionally, bearing down on Thor's soft, open guts.
Hulk's hands spanned across his body: one wrapped around his chest, the other grabbing one leg. He eased his cockhead into Thor like he was using a fuck-sleeve. The pressure of his hands changed slightly as he eased Thor's leg up — hole stretching wider — and bore down, fingers across his chest digging into his muscle. Even the stretch of three fingers wasn't enough to open him up properly; nothing could prepare him for that monster. Thor bellowed, bloated asshole stretched to its limits, wrapped tight around Hulk's gargantuan cockhead. It twitched, the minute flex almost enough to lurch Thor off the tip entirely, and Hulk groaned, holding Thor down more securely. Hulk's cock rippled and spat, gushing inside him with the force of a blow, making Thor pant and keen. Hulk's cock twitched and pulsed, weak flexes making his entire mammoth shaft lurch and sway, half-dragging Thor with it. Each twitch came with a huge hosing blast, spraying down his insides with a sloppy, foaming pre that burst inside him as a hot wave, gurgled down along his inner walls, and then burst out, pouring down Hulk's length in a slimy flood. Heat suffused Thor's body, washing into him in wave after wave, stinging as Hulk flooded his guts with only his spurts of pre.
Hulk growled, pushing him down further — Thor howled, his gape stretched even further beyond, warped into a slick, open mouth, hungrily slurping along the fat, blunt dome of Hulk's monstrous cock. Thor's internal muscles spasmed wildly, uselessly clenching down on the implacable force of Hulk's cock. Hulk fucked Thor on his cocktip, working the huge rubbery ring of his gaped asshole over his broad cockhead, digging deeper with each push. The huge rubbery flange of his cockhead, coated with pearly papules, dug into Thor's splayed asscheeks and compressed, taut and springy as Hulk crammed himself into the tight confines of Thor's body.
Hulk's cockhead scraped inside him with a bone-jarring lurch. His hips ached, internal flesh so flattened and compressed it felt like Hulk's cock was dragging against bone. Before he'd even wedged his whole cockhead inside him, Thor's stomach bloated out, blunt tip warping out his abs into a taut swell. Hulk sunk the whole thing inside him, letting his stiff, rubbery flange scrape over Thor's pulpy guts as it fit into place. Once it was soldily sunk inside him, Hulk flexed his cock, flaring his cockhead wider, and Thor's entire body creaked and groaned from the implacable spread. His prostate was crushed against Hulk's cockhead, the pressure a constant stimulation. Thor bellowed, eyes rolling back into his head as his entire body spasmed in the strongest orgasm he'd ever had: every nerve on fire, vision burning away into brilliant light.
Thor gasped for breath, entire body sheened in sweat and Hulk's dripping pre, sheeting down his sides as he trembled under Hulk's implacable force. Heat burned through him, the pressure of Hulk's cock inside him more than anything he'd ever thought possible. His cock, turgid and limp spilling across Hulk's stomach, twitched and spasmed, pissing out a watery mess of pre and cum as Hulk rearranged his cockhead inside of him.
"Hulk fuck," Hulk growled, flexing his cock again — that alone wringing another mind-blowing orgasm out of Thor — and then bodily dragged him down his cock, groaning as he finally got to sheath his cock in another living being. Thor's already-bloated belly swum and stretched: first in a growing dome, and then more and more lumpy and lopsided as the swollen imprint of Hulk's cock itself made itself known through Thor's impossibly-warped skin. Thor's mouth opened in a silent bellow, air crushed from his lungs by the sheer size of Hulk's cock. Lightning burst through his body, spasming across the distended lump of Hulk's cock, and Hulk crooned, cock firing another huge burst of pre into Thor's body, making his stretched belly gurgle and churn.
Hulk fucked him brutally. He held Thor in place with one hand, holding him aloft entirely spired on his cock, and slammed his hips forward, hooting as he watched Thor's belly bloat and hollow with each thrust: the outline of his cock clearly visible, with Thor's skin only thinly clinging around it. Each burst of pre softened the outline, momentarily, adding to the sloppy gurgle that came with each thrust: slime flooding Thor's rearranged guts, sloshing through him until the excess burst out of him, splattering down the root of Hulk's cock. He only wedged about half his cock inside, the rest slimy and slick with his excess pre, pouring from Thor's wrecked hole. He used Thor's body like a fucktoy, thrusting up into his broken gape, snarling and roaring as he bashed his cockhead against Thor's ribs with enough force that anyone else would be killed.
Thor took it: arms slack and bouncing, legs just holds for Hulk to grip on. His eyes burned with energy, fiercely glowing, and lightning arced over his skin, twisting tightly across his bloated belly. He soundlessly gasped for breath, eyes rolled back in his skull. His cock and balls bounced between his thighs, jolted with each thrust, erupting with sloppy bursts of cum randomly, whenever Hulk's monstrous cockhead scraped inside him the right way. More than that, there was the pounding inside him, a twisting, spasming heat in his ass that had nothing to do with his dick. Each thrust burned, so far beyond too much, and still Thor found himself desperate for Hulk to keep up his brutal pace, to keep scrubbing his cock through his ruined guts. He sobbed, soundlessly keening as Hulk pulverized his guts, lost to all sensation save for the insistent pounding inside him as Hulk used his ass.
Hulk came with the force of a bomb. His cock flared, cock-ridge fattening even wider, lodging Thor in place, and his entire shaft shuddered, sending Thor swaying through the air, body rippling from the force of each shot. His belly bloated, gurgling and squelching incredibly loud through his thinly-stretched skin. Hulk roared through his orgasm, hand encircling Thor's chest squeezing down on his cockhead through Thor's body. Cum erupted out of him, thick and green-tinged, milked out of his flooded guts by Hulk's rhythmic squeezing. Hulk shallowly fucked him, cockhead rising and falling just under Thor's ribs, its clear imprint softened by the wet heft of what had to be gallons of cum sprayed into his ruined guts; Hulk wrapped his huge hands around his chest and wrung him out, squeezing down whenever his sloshing belly grew too heavy. Sharp, pressurized squirts of cum burst from Thor's wrecked hole in slimy gushes that sprayed down all over Hulk's thighs and balls, coating them in a slimy lather of his churned-up issue, dripping down to the floor in huge, creamy dollops.
Hulk stilled, only softly playing with his cock through Thor's gut. The building, overwhelming sensation of getting fucked faded away, and Thor almost sobbed as it left. Without the incredible force of Hulk's thrusts, he could find purchase on his thighs, feet braced as he squatted on Hulk's still-hard cock. It still sluggishly flexed inside him, and the force of each motion was nearly enough to knock Thor off his perch on Hulk's cum-glazed thighs. Each throb of Hulk's cock gushed cum into him rippling bursts; the weight of it built up inside him, gurgling lower until excess finally erupted out of him in great stringy bursts.
"Hulk, buddy, why didn't we do this before?" Thor grinned at Hulk, hands braced against his broad green chest. He felt drunk with endorphins: entire body flushed, hot prickles of sensation burning everywhere the Hulk touched him. His ass burned; the slow churn of Hulk's cocktip inside him sent impossible sensations shooting through his entire body: heat spilling up his chest; cock lurching to life, already sheened with his own cum; nipples stiff and aching.
His thighs burned as he fucked himself; thick, rubbery squirts of Hulk's glowing-green cum sprayed out of him, gushing down his legs, sheening the impossible bulk of Hulk's shaft in a fresh layer of slick lube. His bruised, drooping asslips slid across the fat crown of Hulk's cock, wetly slurping and squelching, and when he dropped down to suck his entire cockhead back into his broken ass they both groaned; Thor came again, orgasm like a punch to the gut, a sudden heat burning across his body that left him thrashing and shaking, his fat cock fucking between Hulk's enormous pecs as he glazed them with his load.
"Puny Thor is durable," Hulk growled up at him, giant hand sliding up from where it was stuck to Thor's thigh. "Makes good cock-sleeve." He wrapped his hand around Thor's entire stomach, not squeezing, just gripping, but his thumb dug into Thor's bloated belly — Hulk rubbed his thumb across his cockhead, stretched out through Thor's skin — and that was enough to force out huge gurgling bursts of cum from his overfilled guts, wringing him out.
Hulk was still hard inside him.
"Hulk," Thor groaned, fucking himself shallowly, knocking his own breath from his lungs as he bore down on Hulk's colossal cock. Hulk had only dared fuck him with half his length, but now Thor needed it — needed more. Thor sunk down, thighs shaking as he swallowed up more and more of Hulk's shaft. He dazedly adjusted, twisting himself to the side to try to work Hulk's giant cockhead through the curves of his guts, rocking himself deeper, deeper, deeper down Hulk's inhuman, beyond-divine cock. His swollen stomach grew more and more taut, letting the imprint of Hulk's cock through his gut show itself more and more starkly, until his flesh was stretched so tight Thor could see the swollen ridge of Hulk's cockhead, shuddering and flexing, under his grotesquely-warped skin.
There was a dizzying clap of impact as Thor's ass smacked against Hulk's lap. His giant balls were burning hot as they rolled into place: huge lopsided mounds, jammed unevenly against his back. Thor grinned up at Hulk — around the impossibly-distended bloat of his stomach, stretched out to mid-chest — and flexed his thighs, rocking himself an iota of Hulk's cock, feeling its answering lurch send his entire body swaying to the side. "Ready for round two, big guy?" he asked, grinning at Hulk's answering roar.
