“I’ve got you now, Wesker!” Chris shouted, barging into a room where his intel told him that his old captain was with his pistol drawn. But the room was empty aside from a box on the counter in the center of the room with a note on top of it. Chris cautiously walked up to it and lowered his gun, wondering if it was meant for him, some sort of elaborate scheme planned out by Wesker.
Chris grabbed ahold of the note and picked it up, and at the same time he could see that inside the box was what looked like a gun and instantly it fired at him. He didn’t have time to react as it happened instantly, but instead of a bullet aimed at him it was some liquid from a squirt gun. Chris groaned, wondering if Wesker was resorting to pranks at the very ‘height’ of his game.
“Very funny, Wesker. I’m so amused.” Chris grunted, wiping the bright purple liquid off of his face. Chris felt annoyed, the liquid had already seeped into his skin and though he had wiped most of it off, a good bit had already sunken into his skin.
Thankfully, his skin wasn’t showing any signs of damage. But then again, that could be even more worrisome that his skin wasn’t showing signs of infection. Chris had been so cautious the entire mission and the second he let his guard down a simple prank had gotten him splashed with some unknown chemical. Although his body did feel a bit strange, he brushed it off as a placebo until he was sure something was very wrong with himself.
“Resorting to pranks, that’s a new low even for you, Wesker.” Chris called out, relatively sure Wesker could hear if not see him at that moment. The entire cargo ship was heavily monitored, Sheva and him had only just gotten separated before he had gotten on the ship.
“And yet, it worked perfectly, old friend.” Wesker’s voice called out from the speaker in the corner of the room.
“What did you do to me, Wesker?!” Chris shouted out.
“You really did it to yourself Chris, I taught you better than falling for something so rudimentary. I know you know better than that.” Wesker taunted Chris and that sensation he felt before began to intensify and now he was sure there had been something in that liquid, “Don’t call for backup Chris, the transformation will be complete before they even get here.”
“And what exactly are you going to do with me once I’m another zombie? Just be a part of your army?!” Chris shouted out, clutching his stomach. But he heard chuckling from Wesker over the loudspeaker much to his annoyance. A dull pain was now emanating from his stomach where the liquid had seemingly congregated inside his body.
“No, Chris. I have much better plans for you, much bigger plans. Enjoy your transformation, I’m doing you a favor really.” Wesker’s voice trailed off as Chris felt the dull pain in his stomach dissipate. He went to sit down for a moment to catch his breath but looking at his hand something felt different, Chris was beginning to catch on to what Wesker was alluding to, “I made this just for you, old friend.”
Chris groaned seeing his hand looked bigger than normal and looked at his forearm and then bicep noticing they too looked bigger. Chris himself was noticeably muscular but whatever Wesker had given him was enchanting that even more. He felt his body begin to swell, pushing outward as his clothes shrank on him.
“You’re just… gonna… … make me a bigger threat… Wesker..!” Chris groaned, his voice deepening slightly as his head pushed upwards and his muscles swelled further. Chris’ tucked in shirt slowly began to untuck itself and expose his slightly hairy abdomen. His pants beginning to expose his ankles and Chris’ boots tightened against his growing feet.
“And what a magnificent specimen you’ll become. I’m jealous Chris, you’re testing out something I wanted for myself. But for an old friend, I’ll make an exception.” Wesker’s voice called out over the loudspeaker with a soft chuckle following it. Chris could tell Wesker was close to the microphone as if he could see Chris right now and was intently watching him. Chris groaned once more, watching his biceps swell even bigger, pushing his sleeves up onto his shoulders. His pecs ballooned in size, stretching the collar of his shirt out. Chris felt all of his clothes tightening on him simultaneously. It was getting to be too much.
“WEEESSSSSSKER..!” Chris shouted out, feeling his head approaching the ceiling and a good bit of his abdomen being exposed now by his shrinking shirt as it tightened across his broad chest and shoulders. His nipples poked against his stretched shirt, making Chris shiver from the friction between his nipples and his ever-shrinking shirt. Chris reached his arms up and pushed against the metal ceiling.
“You don’t have long left before you’re outgrowing that room, dear Chris. My, I wish I was in your position. Don’t fight it, Chris, embrace it.” Wesker told him, his voice crackling through the speaker. Chris grunted, his toes bursting through the front of his boots. The rest of his feet were still concealed by the remaining in-tact parts of his boots, but the rest wasn’t far away from being too small.
Chris couldn’t help it and moaned deeply, the crotch of his pants hugging his bulge which too had been growing bigger and bigger. His belt strained at his waist and his pants began to sag downwards to accommodate his increasingly bigger bulge, and at the same time his pants rode up further and further, pushing up to his calves.
“Ooohhhhh… fffffuuuucccccccccckk..!” Chris moaned, his voice deepening mid-sentence by magnitudes. He felt his hair brush against the ceiling and his sleeves rolled up to his chest. The room was looking smaller and smaller by the second, and Chris began to panic wondering just how big he was going to get, “I’ve… I’ve gotta get… outta here.”
Chris knelt down, practically waddling to avoid his hair from touching the ceiling which was becoming increasingly more and more difficult. He grabbed onto the door handle and ripped the metal door off right on its hinges, Chris blinked looking at the door in his grasp. His biceps barely strained to do it.
“Not even ten feet tall and you’re doing impressive feats of strength like that.” Wesker commended Chris from a loudspeaker in the hallway outside the room. Chris groaned, pulling himself out of the room and into the hallway outside of it, having to turn sideways as his shoulders were far too wide to exit the room normally. The doorframe itself only came up to Chris’ nipples, the growing man had to crouch down in addition to turning himself sideways to squeeze through the chokepoint.
Chris stood up fully, the hallway had a much higher ceiling thankfully but he wasn’t sure if he could make it to the top of the ship in time before he outgrew doorframes entirely. Wesker had laid the trap when Chris was already below deck. Walking hurriedly to the exit, Chris felt a significant growth spurt rock his body and many things happened in quick succession.
With a loud rip, Chris’ shirt split down the middle of his wide, muscular back and fell to the floor. Chris watched it flitter uselessly down to the floor exposing his enhanced physique. His pecs bounced with each hurried step Chris took, and Chris’ rippling abs shone with a light layer of sweat from how worked up Chris was becoming. The boots he was wearing began to fall apart entirely, splitting at the sides and dangling from his ever-growing feet. They thudded against the floor as the boots were discarded haphazardly, Chris nearly tripping over his immense feet from how unaccustomed he was to having even bigger feet.
His pants weren’t far behind as his belt burst off of his body, leaving his pants vulnerable to Chris’ ever-increasing in size body. Chris felt his bulge throbbing from all the growth, it wasn’t letting itself be ignored by how much it and Chris himself got worked up by the feeling of growing.
“Not long now, Chris. You’re about to experience the best part of my C(X) Virus.” Wesker spoke once more over the loudspeaker. Chris cursed Wesker for doing this to him, it wasn’t that this wasn’t something Chris didn’t want. It was just when it happened, not at a time like this. But he was brought out of his daydream to see the exit was just up ahead, but so was his head to the hallway ceiling.
“Jus t a b it furth er, and I’ m good t o g o. ” Chris told himself, pushing himself to his goal as an overwhelming force was slowing him down. His skin-tight pants split down the inseam, shredding and leaving Chris in only his briefs which were riding up his thighs and outlining his immense bulge quite well. The growth was beginning to speed up now, it was the part Wesker seemed most interested in seeing Chris undergo.
Chris’ bulge wobbled from side to side, throbbing and stretching out the fabric of his briefs to its limits. And as Chris’ hair once more brushed the ceiling, his briefs shredded apart, his cock and balls flopping out freed from the tightening clothes. Chris moaned again, feeling the undeniable urge to relieve the built up tension that had been forming below. But as the forces in his head fought each other, his growth only sped up more and more, making his muscles bulge and balloon even faster and his height soar past anything he could dream of.
His head pushed up against the ceiling as his growth accelerated, pound after pound of muscle compiling on his already impressive form. His body pushed taller and taller to accommodate the compounding muscle stacking onto Chris’ bulky form. The hatch was now right above him, and reaching up he could grab the wheel with a single hand, or rather he was beginning to have trouble grabbing it with a single hand as his neck and now back pushed up against the hallway ceiling. His body grew faster and faster.
“Magnificent, truly a work of art.” Wesker dawdled, reveling in seeing Chris being the perfect specimen for his virus. Chris ignored his former captain and ripped off the hatch and looked up into the cloudy sky above the ship. He reached an arm through and could only get up to his elbow through it, he was growing too fast. There was no way to get to the top deck with how big he had grown, only a few minutes ago he had been able to squeeze his way through a doorframe sideways.
Chris looked around as his back fully pushed against the ceiling, the metal framing of the ceiling above him groaning against Chris’ bulky body. Dragging his arm back through the shrinking opening, he nearly got his rippling forearm stuck from how much he had grown in that small space of time.
“I’m getting… too big..!” Chris told himself, feeling the entire might of his back pushing up against the ceiling as he knelt down and compressed himself as much as possible despite his body growing faster and faster. No matter how he twisted or contorted his swelling body, his form pushed against the walls with every action.
“Don’t fight it Chris, you were already quite big to begin with. Those biceps… truly spectacular. And now, they’re enhanced even further with a bit of help from yours truly.” Wesker gloated fondly, the entire view of his camera was obscured by Chris’ immense ass, both cheeks round and plump.
“ Enough… W-We sker..! Y-you’v e got a… … cure f or this… you would n’t have done thi s… … to me… with out a continge ncy pl an..! ” Chris shouted, feeling his entire body pressing up against every surface of the hallway. Laid out flat with his front against the cool metal, wide back against the ceiling, and his bulky arms against the walls, he was now stuck in the hallway. His cock and balls trapped beneath his abdomen. He was having trouble focusing with his dick begging for attention, and to its credit, it was getting what it oh so desired. With every shift of Chris’ body, his dick rubbed against his hairy washboard abs, he was beginning to subconsciously rub his dick against his abdomen.
“Even with all that size, you’re retaining your mental capabilities. You know me too well Chris, but I can’t let you have the cure quite yet.” Wesker paused, watching with bated breath as Chris’ growing body pushed against the walls of the hallway, the metal creaking and attempting to hold back the growing man. Chris groaned, his cock throbbing eagerly as it pushed against his abdomen, growing alongside him and somewhat faster than him too.
“ I’m gonn a sink th is ship i f yo u… d -do n’ t! ! ” Chris shouted, the metal groaning against his bulk. It wouldn’t last long, and Wesker seemed hellbent on letting Chris outgrow the hallway. And if he outgrew the hallway, who's to say he wouldn’t outgrow the ship, Chris worried that he wouldn’t stop growing. He just hoped that part of Wesker’s contingency plan involved him not outgrowing the cargo ship entirely.
Chris’ body lurched with size, the metal around him practically shredding apart as Chris pushed his body upwards to the top deck, he moaned once more, his dick flicking precum as he did. Fully erect and standing perpendicularly from him with a slight droop from its own immense weight, Chris’ dick throbbed eagerly from the friction that had built up.
Looking around, he saw that he had indeed grown significantly, the nearby crane wasn’t so imposing anymore. Chris could see the top of it standing on the top deck, the metal flooring of the top deck barely held itself together with Chris’ immense weight on top of it and an indent in the surface was left behind by his large feet. The wildest part was all the cargo containers around him looked so small, one had even fallen into the hole Chris had burst out of from below deck. He could pick one up with some effort, being half his size.
“You truly are my finest work of art, Chris.” Wesker’s voice called out. From across the ship on the top deck he could make out the unmistakable silhouette of Albert Wesker himself standing there proudly with his arms outstretched towards Chris. The giant man grimaced angrily, Wesker was viewing him as some absurd art project.
“ Enough, Wesker! I’m done with this game of yours! ” Chris shouted, his deep voice booming across the entirety of the Tricell Tanker, Wesker didn’t move. Chris began to make his way towards Wesker, clambering over cargo containers with ease considering his immense height.
“Oh but the game is over Chris, haven’t you noticed? You’ve stopped growing just as I intended. And at an immaculate height of forty one feet tall and nine inches.” Wesker gloated, awaiting Chris’ arrival. Tumbling over a tall stack of containers and falling onto another stack, Chris felt little pain. His muscles and enhanced physique protected him from nearly all damage he would have sustained.
“ Give me one reason I shouldn’t finish you off right now with the size you gave me! ” Chris’ voice boomed as he made it halfway across the ship, Wesker simply cackled. He was amused by Chris even when he had given the giant man such an incredible size advantage over him. With every movement, Chris’ pecs bounced around. Huge and with substantial nipples, they drew the attention of the eyes across the ship.
“Because I know you Chris, and you don’t want to kill me. You want to know the why as to why I am doing all this. The Uroboros, The C(X) Virus, everything, you want to know all those details for your neat report for the B.S.A.A.” Wesker continued his speech as Chris approached him. Pushing aside containers, Chris’ biceps flexed. Wesker was watching with a smirk, Chris’ muscular physique needed the boost.
“ So, what’s in it for you? Why make me a giant?! ” Chris demanded to know, coming upon an open area in front of the bridge. A trail of footprints in the metal surface of the cargo ship were laid out behind the giant man. Matching the trail of giant footprints, flecks of precum were strewn about the dented cargo containers. Chris now stood face to face with Wesker. The man with sunglasses stepped forward to the railing outside the bridge and Chris stepped forward as well, his face level with Wesker’s entire body. Wesker compared to him could stand on his shoulder and still be shorter than him.
“Because I wanted to study you , Chris. I did all this for you.” Wesker answered, causing the giant man to pause for a moment, “I’ve studied you for a long time, you always wished to be bigger. My my, when I saw you after all these years here chasing after me, I couldn’t help myself.”
Chris stayed silent, feeling a deep mixture of anger and rage. But overwhelming it was a deep feeling that he had buried long ago that was resurfacing. Wesker could see it on the giant man’s face and was happy to see that the feelings weren’t one sided after all. All those moments from long ago meant something to both of them even despite all their current differences.
“ Captain… ” Chris said impossibly quietly in his deep voice. He leaned forward, and Wesker did the same, “I’ve missed you dearly, Chris Redfield.”
The two kissed, Chris’ lips taking nearly up the entirety of Wesker’s face. Wesker gently held Chris’ stumbly chin, rubbing it softly and gingerly. He missed the feeling of being so close to a brute of a man, the only thing was Wesker knew how to tame the beast. Chris kissed Wesker softly, letting his lips gently overwhelm the normal sized man. Wesker himself planted many kisses on Chris’ much larger lips and felt that his decision to go through with infecting Chris with the C(X) Virus was a very good choice.
The two pulled apart and once more impossibly quietly and almost sheepishly, Chris said, “ I missed you too, Albert. ”
The giant man was blushing profusely, almost flustered. Wesker loved seeing how well he could fluster Chris with his plans, they always worked to perfection on getting Chris flustered or more than just flustered. Chris paused, unsure what to say his dick standing out from his throbbing idly, aching for a release. And with the friction it had built up before with Chris’ abdomen, it wasn’t far from an explosion.
“Just like old times.” Wesker reminisced, jumping down from the bridge and landing smoothly on the ground by Chris’ feet. Standing just taller than Chris’ ankle, Wesker patted the giant man’s leg and Chris obliged, sitting down carefully as to not rock the ship too hard.
“ Just like old times. ” Chris blushed further and his cock throbbed even harder knowing what ‘just like old times’ meant. Wesker’s desk had seen everything and anything in the S.T.A.R.S. office.
“You might be much bigger than when we previously were intimate, but I have new tools to best make use of your size.” Wesker grinned, climbing up and standing on top of Chris’ ankle. The giant man looked down at Wesker, his anticipation solidified by his massive erect penis.
“ What do you have in mind, Wesker… I’m a bit too big for… you know. Can’t bend me over your desk like you used to. ” Chris remarked sheepishly, worried that someone else would hear him even when he was speaking quietly. Wesker took off his sunglasses, looking at Chris with his red slitted eyes intently.
“Oh, my dear Chris. I’ve been aching to show off my new powers to you. And this is the perfect opportunity to do so.” Wesker said, looking upwards at Chris’ throbbing dick. With every word Wesker said, it impossibly turned Chris on even more, “Now, you’ll need to move some of those containers. With those magnificent biceps of yours, it should be quite easy for you, Chris.”
Chris made quick work of the containers, making two stacks of containers. One for himself to lean over and one for Wesker himself to stand on. Placing two on top of each other for himself to lean over, and the same formation right behind him for Wesker to stand on. The giant man wiped the sweat from his forehead after moving all the containers, even for a giant, they were still quite heavy. Wesker had kept his eyes on Chris’ muscles, specifically his biceps as Chris lifted the containers, admiring them flexing, the veins bulging in Chris’ biceps with the heavy lifting. Chris’ dick throbbed and stayed erect the entire time, flicking more and more precum all over the ship, it amused Wesker.
Chris leaned over the two containers stacked on top of each other, and with a great leap, Wesker jumped up onto the containers behind Chris. On full display in front of Wesker was a view he had missed dearly, only things were quite different from how they used to be. Chris’ huge ass had drawn the blonde-haired man’s attention now.
“This is the power that’ll make this possible for us again, Chris.” Wesker smirked, holding out some tendrils of Uroborus from his arm. Chris furrowed his eyebrows nervously, “Don’t worry Chris, that C(X) Virus gives you complete immunity to Uroborus. Now, kneel. Open up for me.”
Chris whimpered, and Wesker’s smirk widened. He had missed breaking in Chris and pushing through that punchy exterior and opening him up to the truly submissive behavior Chris was very much capable of. It didn’t matter how big Chris was, his submissive nature was always somewhere deep within the giant man, usually buried under a ton of anger and fight. Chris’ dick bucked against the containers he was leaning over, “ Captain… ”
“Due to your increased size, I don’t have to hold back.” Wesker grinned, unzipping his pants and pulling out his own dick. Chris looked back and was surprised to see Wesker was already erect, his cock flopped out and stood outstretched from him perfectly perpendicularly. Chris whimpered louder, just seeing Wesker’s dick after all this time made his huge cock spill out a large amount of precum. The area at Chris’ feet became a puddle of precum.
Chris couldn’t speak, immobilized by his need to be intimate with Wesker, he watched as the tendrils disappeared underneath his cloak and re-emerged around Wesker’s cock. Adding onto it they swirled around it making Wesker’s already decently-sized cock even bigger. The tendrils formed a big sleeve around Wesker’s cock, sticking out over two feet from the mastermind. Wesker moved forward, placing his hands on Chris’ gigantic ass cheeks. Using more tendrils he parted Chris’ ass to enter the giant man with his tendril-sleeved cock. Wesker’s tendril cock pushed against Chris’ hole and with surprising ease, Wesker entered the giant man which came with a loud moan from Chris.
“You’ve been busy Chris, or are you just that eager for me? You opened up that easily.” Wesker taunted fondly, pushing his tendril cock in further, grunting as he did. Even Wesker was surprised by how good it felt, the tendrils enhanced the feelings on his dick as he plunged himself into the giant man. Chris was already breathing deeply and gripping onto a nearby container, so hard that he was bending the metal on it.
“ Oh hh h f f fu u uc c ckk k ! ! ! ” Chris moaned loud enough to be heard for miles, and Wesker just enjoyed the ambiance Chris provided. Pushing himself so he was in as far as possible, Wesker moaned too.
“You remember what I told you long ago when we were in this same position with you on my desk?” Wesker asked, tendrils snaking around Chris’ body aiming for the giant man’s cock. Chris shuddered, Wesker was beginning to fuck him slowly now.
“ W-wesker don’t, you’ll make m-me… me… ” Chris pleaded, he wanted this to last forever. And Wesker saying what he used to would make him cum, it always did before and this time wouldn’t be any different. The giant man gasped, feeling the Uroborus tendrils wrapping around his gigantic cock and slowly jerking him off. Wesker simply grinned hearing how much Chris was loving it.
“You fail to realize you’re not the only one close to climaxing, old friend…” Wesker trailed off, fucking Chris harder and harder. Slamming his hips against Chris’ ass he was able to fuck Chris harder than he ever had before due to his new found power. The tendrils on Chris’ giant cock made it even more difficult to hold back and with a roaring moan he was at the tipping point. The puddle of precum at his feet had turned into a lake, both of his feet now surrounded by it.
“ Albert… … say it… please… ” Chris pleaded, feeling himself already tip past the point of no return. Wesker allowed himself to do the same and took a deep breath between grunts.
“You’re all mine Chris, and you always will be.” Albert commanded, and Chris roared once more, his cock shooting out a load so fiercely that it blew a hole in both sides of the bottom shipping container. Chris’ giant load plastered itself everywhere on the ship as his cock bucked in absolute pleasure, Wesker’s words had made him cum harder than ever before.
Wesker came at the same time, taking his tendril enhanced cock out of Chris just in time to shoot his load all over Chris’ gigantic ass. The giant man whimpered as he finished cumming, slumping over the shipping container and making it groan from taking on so much weight from Chris. Wesker jumped, getting up the back of Chris’ waist and walking up the giant man’s wide muscular back. Getting up on Chris’ shoulder the giant man slumped over so he was leaning up against the damaged shipping containers with Wesker now sitting on his shoulder. The giant man’s enormous pecs bounced from the movement, catching the eyes of the man on Chris’ muscular shoulder.
Chris couldn’t find his words, he simply leaned his head over and kissed Wesker once more, their size difference on full display once more as Chris’ giant lips overtook nearly all of Wesker’s face. The giant man had noticed a hint of blushing on Wesker’s face for a brief moment, and was surprised to see it.
In an odd turn of events, Wesker spoke of his feelings to the giant man, rubbing Chris’ shoulder fondly with his gloved hands. The mastermind’s tone was hard to pinpoint but for once it sounded truly genuine, “I wished for nothing more than to meet you here just like this. After all I told you before. I made this virus just for you, Chris.”
