My Roommate’s a Were-Hulk: Halloween Edition Summary: Noah and Zach are approaching Halloween and are pumped up for a costume party. But when Zach gets second thoughts at the last minute, the two discover something within them that unleashes their inner beast for Halloween. A longer one-shot, quickly written. It’s been a while since I’ve written a story, so I took some liberties with my style here. (I don’t know if it works lol.) I wanted to separate this from my other thread since it’s a bit of an “event” kind of story. This might be the longest muscle growth story I’ve ever written and the fastest I’ve ever written one. Enjoy some more Hulk shenanigans from yours truly. The Incredible Hulk is a copyright of Marvel. I claim no ownership. --------------------------- “Hurry up, bro! You’ve been in there for 20 minutes!” I was getting annoyed. I didn’t get this dude an invite just for him to get cold feet at the last minute. I knew someone in ATO, so it’s not a big deal for me, but Zach didn’t. Mark fuckin’ grilled me, and I had to convince him that Zach will be chill and that he’s a ride or die. Now I’m standing here in just my purple shorts, half naked, half painted, and the rest of my green body paint still sitting in the bathroom. “They’re doing the costume contest at like 10:30. We’re gonna miss it if you want a chance, Zach!” I looked at my phone, and it was already 8 and we were gonna pregame at my girl’s place in half an hour. And my paint job was gonna take longer than that. Trying not to tear the door down, I tried to wait patiently outside the bathroom door, hearing the whirr of the vent inside. I pulled out my phone, idly switching between apps hoping that my roommate would finish. As I was scrolling through my notifications, my phone buzzed and a text from her — Jen — popped up. Where are you? dont forget we’re taking pics, it read. “Shit!” I hissed. I texted a quick reply — something fell off of Zach’s wizard costume and he had to fix it. I turned back to the bathroom door and started knocking like I have been for the past 5 minutes. In the middle of my knocking, the door swung open and there stood Zach: 5’9”, short and neat dark brown hair, pale skin, scrawny stature. He was just wearing his vest and some shorts as he walked out. “Finally, bro!” I called out. But there was a weird glum, anxious look on his face. Zach was always a sensitive dude, but the look I was seeing right now wasn’t anything I’d ever seen from him before. Like there was something heavy weighing on him. Ever since the party got pushed forward a day, Zach’s been acting like he didn’t wanna go anymore, even though he said he did. He was so excited before, but now… “Dude, are you okay?” Zach sighed and stopped in his tracks beside me. “I’m… I’m fine. I don’t know, I just don’t really feel like going out tonight anymore.” He looked kinda scared, to be honest. I didn’t know why though, and I couldn’t understand what was up with him. We’d been roommates for almost a year now and despite how different we were, I really felt like we could tell each other anything. But now he’s giving me this weird, blocked off attitude that I’d never seen before and it was honestly making me upset. “Why not?” I asked him. He clearly had a good reason to say, but all Zach said with a simple defeated look on his face was, “I’m just a little tired.” I huffed and wrapped my unpainted arm around his shoulders. “Come on dude. It’s our last Halloweekend of college, bro.” I said to him, trying to study Zach’s expression. I hung over him trying to reach his height. “Look, I know you’ve been stressed and exhausted all week, but that’s just more of a reason to go out. You deserve this.” Zach seemed hesitant. His brown eyes kinda just fixated on a point on the ground to avoid looking at me. You could tell there was clearly a lot going on in his head but I wanted to convince him to take a real break and hang out for once. “I just… Well, you just never know what can happen sometimes,” he said quietly. “What could happen? I can promise you, it’s not like we’re going to some stranger’s house. We — I know these people. It’ll be chill…” I could tell Zach was feeling super tense. “There’s… a blue moon tonight.” “Is that it?” I said. I wasn’t super sure if he was serious or not. “I didn’t know you were superstitious about full moons.” “I’m not, but I just…” “Need to chill! You need to hang out and take the edge off,” I said taking my arm off Zach. “You promised that you’d come out tonight. Plus, you’ll get to meet some new people and it’ll be fun.” Zach just stood there in silence. I couldn’t tell whether I made things better or worse, but the dude sighed and finally looked up with me, with an awkward smile on his face. “You’re right. Yeah, I’ll go,” he said. I was relieved, but there’s something about his tone of voice that made me question whether or not he knew something I didn’t. “Hell yeah,” I said. “We gotta finish up soon though, Jen’s waiting on us.” I wasted no time to head into the bathroom where I could finally resume putting my costume together. I positioned myself in front of the mirror and looked real quick. I chuckled as I took in my incomplete sight. Basically everything about me was still the same — 6’2”, shaggy messy dark blond hair, blue eyes behind my glasses — but I was shirtless and my left arm was painted green. I wasn’t as scrawny as Zach at all, and I had a good lean build going on since I started working out, but I was still a long way to go til I become the next CBum. I adjusted my glasses right before hitting a quick bicep pose just to check myself out. Yeah, Zach was the nerd but I’m the four eyes here. I went to work painting the rest of my torso green, glancing at the light up Hulk mask laying on the counter. Yeah, I was going to be the Hulk. Was I going to win the costume contest for creativity? Nah. Am I the biggest dude in the room? Also no. But I started getting serious with lifting six months ago, and I planned all summer to make my gains, my costume. I figured it would be easy and simple, and there’d be a good joke in there about me acting like a douche just to show off my biceps. Simple was true, but easy was not, considering I can’t wrap my arms around to actually paint my back green. “Zach? Could you help me paint my back?” “Yeah, sure!” Zach turned the corner and I saw him at the bathroom door once more, this time decked out in his cool ass wizard gear — robe, hat, vest, accessories, everything. I clowned on him for basically putting together some nerdy cosplay, but I couldn’t deny that his costume looked legit. Like, genuinely good. Like this dude really hand painted fake wands! The only thing that was amiss was the corny fake beard, but I think it works out for him. Meanwhile, I had patchy green paint that already looked rushed. I handed him the body paint and the messy sponge I was using. “Sorry, I should’ve told you to wear gloves or something.” “It’ll wash out,” he said in his signature candid tone. He went to work, and I kept fidgeting as he applied the paint to my skin. “The Hulk, really?” he asked in a playful tone. “Well it’s so I can show off my gainz, you know?” I shifted into a teasing tone, mocking those dumb roided out bodybuilders. Respect to them, though. “What gains?” Zach teased back. “You really think that gym helped that much?” “I don’t know, you tell me,” I said to him. In a quick motion, I jumped to do a quick bodybuilding pose, trying to show off my biceps and lats once more. I knew he was gay, but I liked teasing him with a quick flex or two sometimes. It was always in good faith, considering Zach was the one that would suggest it half the time. I must have shocked Zach though. He kinda jumped, and so did some paint from the small body paint jar, landing all over the bathroom and me. We apologized to each other at the same time: me for scaring him, him for causing a mess. But I realized the one that had it worse at this point was… him. “We can just clean this shit tomorrow,” I said, thinking he was frozen ‘cause he thought he just inconvenienced me. But looking over him I realized, “Yo there’s some paint on your…” “I know. Shit!” A bunch of paint splashed all over his robe and vest. That was half of his costume! “It’s ruined,” he whispered to himself. I rushed to grab a towel. “Chill, don’t freak out,” I told him. I tried wiping the paint off his costume, but ended up smearing it. I tried to tell him to shift, but his eyes were instead fixated on the bathroom window behind me. “Hey, you good?” When I got no response, I decided to look around and see that the full moon was in full view. Damn, did I just confirm his superstitions? “Yo… Earth to Zach… Are you good?” I noticed his breathing was starting to get heavy, like he was about to get into a panic attack. He shook himself out of it though, literally shaking his head. But he was starting to seem disoriented. “I… Oh fuck. Shit. My costume,” he muttered, as if he forgot what had just happened. He looked dazed and confused. “I just need to…” “Zach?” “I need to… calm down,” he said. It sounded like he was out of breath. He clumsily stepped out of the bathroom like he was already drunk. “Need to… calm down…” “Hey? Zach? Are you good?” I left everything behind to go after him. I watched him stumble into his room and slam the door. “Let me get you some water, bro!” “S-stop it… Noah, just go without me…” I heard him call out. His voice sounded all weird… Like deeper or something. Maybe pained? “Nah, you made a promise, bro. Let me help you, I swear it’s fine,” I said to him as I rushed to the kitchen to get a glass of water. “Seriously, Noah… Listen to me… Just go.” I came running back to Zach’s room. “Look, I’m not going —” “Noah, STOP.” I stopped myself right at Zach’s door frame, hearing him put bass into his voice that I’d never heard before. I saw Zach on the floor, holding his head, bathing in the moonlight pouring through his room’s windows. He was shaking. “Just go, Noah. I’m serious. I’m gonna wreck you if you don’t…” His voice was wavering and inconsistent. I slowly stepped in, placing the glass of water on his desk and kneeling down beside him. “Zach, I’m sorry. I didn’t mean to pressure you, I…” “It’s too late for that, bro.” The sound of his voice made me jump. I sprung up and took a step back. Zach’s voice was never really high pitched, but right now it was bassy, it was powerful. It didn’t sound like him — or at least not the guy putting paint on my back a few minutes ago. “You wanna know why I didn’t wanna go… I tried to fight it… But I’ll show you instead.” “Zach what are you…” The scrawny dude stopped shaking and looked up suddenly from his prostrate position. I started crawling back though, as my little, usually-tame roommate locked his gaze onto me with a strangely confident smirk and… And… “Bro your eyes… They’re… green!” “And that’s just the start of it, bro.” Zach slowly straightened his back, the moonlight coming from behind and casting a light outline around him. It felt like the air inside had gotten thick, and I had no idea that my roommate was about to become the living, best personification of my costume. With a blue moon just a few days before Hallowee, I felt like I was living in a horror movie! (Or a story on some niche internet forum.) Zach’s eyes rolled up as he closed them, shuddering like he just orgasmed. I swear, he even moaned. Then I noticed it, a large bulge in his pants as he hunched over and shrugged his shoulders… which seemed to be… widening? “Fuck… I…” Zach’s normal voice cried out for a little bit, and it sounded like he was trying to suppress what the fuck was happening. “F-f-f-fuck yeah, it’s happening.” He opened his eyes again and glanced at me before it looked like every muscle he had twitched, a full-body involuntary flex of what were currently nonexistent muscles. With the lights in his room being out, the only things that helped me see anything were the moonlight and the light from the hallway behind me. I could only just barely see Zach clenching his hands into fists, his fingertips going green. It began to click for me that Zach was more than human when his costume caught some light, the loose black sleeves of his costume tightening and expanding around some seriously muscled arms. “Zach, you’re… You’re… What are you…” I couldn’t find the words, and I honestly couldn’t believe my eyes. There was something, like, stirring inside me, bro. I can’t explain it. I was watching my roommate transform into some kind of beast and although I was scared, there was something keeping my eyes peeled. “I’m fuckin’ HULKING OUT, bro. You’ve watched the movies.” Zach huffed and grabbed the hooded robe and tore it clean off his back, tossing it against the wall, leaving himself in the black shirt and vest underneath. “Stupid fuckin’ robe.” I watched as Zach flexed his back and streeeeeetched — “Dumb…” — a loud pop and tear sounded as I saw green skin began to peek through destroyed cloth — “Puny…” — he glanced and me and smirked before raising his arms and flexing huge bicep peaks and bursting through the sleeves — “Costume…!” When he ripped his sleeves clean off the seams, as you could see his traps rise and settle into a permanent flex, I could feel the feelings inside become a stirring in my lower region. I’ve been straight all my life, and I’d rather die than cheat on Jen at all, but I was suddenly obsessed with the raw masculinity revealing itself in front of me. And when I saw his chest bursting through his shirt, Zach gripping the vest and tearing it off effortlessly, without any sense of friction, I was as hard as a rock. He’s becoming a fucking god. I slowly dropped to my knees, mouth open, transfixed. My heart was beating so fast as I watched his chest fill out, his shoulders broaden, his back widen, his already huge bulge grow in his pants, his shoulders balloon into boulders, his abs carving out from nothing, his feet tear through his black socks, his calves lengthen and harden and thicken as he pushed up taller than even me. My horniness had to be obvious through my mesh shorts as Zach chuckled as he looked me down. “Yeah. I knew you’d fuckin’ like it. I know what you’re into. I bet you’d like this —” He flexed his arms above his head, and I could see a small dusting hair sprout from his chest, hair in his pits, a bit of hair on his legs and forearms. Then he turned to the side, closer to the moonlight, and I could see small droplets of sweat all over his skin, which was deepening into a warm jade. I could smell him, and while normally I might’ve been grossed out, it only turned me on even more. It felt like an eternity, but in just moments, I’d watched Zach go from pasty 5’9” nerd to this huge 6’10” emerald beast with a physique that easily topped all my bodybuilding idols on Instagram. His hair had gone from brown to a deep forest green, messy and slick with sweat. His breathing was still heavy, but there was a lustful, crazed look on his eyes, and his voice, dropped an octave, just served to show the way the transformation had changed his personality. “That’s right, bitch. I’m everything you wish you were. Zach’s a Hulk.” He flexed his arm again. “Go ahead. Cop a feel, bro.” I slowly got up. Before, my eyes would be looking down on Zach’s head. Standing up straight, I was only able to reach up to his collarbone. I looked up to catch a glimpse at his eyes, his radioactive, gamma green eyes, and got lost seeing every feature on Zach’s face wider, more chiseled and masculine. I reached my hands upward to feel the huge hard muscles stretched out against Zach’s sweaty, seemingly bulletproof green skin. My hands traveled over to Zach’s chest, and in my haze, I tried to squeeze his firm pecs, just to be shocked that my best efforts could only barely make a dent. Something pulled me closer, his musk, the pheromones he was giving off wafting in the air, as I tried to sniff more of him. I couldn’t stop myself. I needed… “You’re so fucking hot, bro…” Zach’s smirk turned into a sneer. “What was that?” “You’re so fucking hot, Zach. I…” I was on the verge of salivating when Zach took me by the chin and kissed me, his tongue invading my mouth. As he pulled my close, I could feel Zach’s sweaty chest smear paint off of mine. I didn’t even think as I pushed my body against his, feeling my dick press against his leg, and his huge, nearly foot long dick, snaking past the waistline of his stretched out pants and pressing against my stomach. I was feeling dizzy, and I was going crazy. I wanted him. I needed this. Zach pulled away and looked at me in the eyes. “That’s right I’m fucking hot, bro. You know it. Nothing like a Hulk. Nothing stronger… Better…” I stumbled backwards and realizing I let a man kiss me, I scrambled to regain control myself. I needed to stop myself. Or did I? Zach hunched over and squinted into my eyes as I tried to steady myself. He grinned. No… No, no no no… “Now you’re gonna see what it feels like, bro. To join my ranks.” Zach stepped away from the window, and I could see his massive, imposing form. I was realizing… I craved it. I didn’t just want to worship him, as much of a god as he is. No. I wanted to be him. It woke inside me. My eyes wandered out the window to the moon. Maybe it was an optical illusion, but it looked like the moon got a greenish tint. I felt my heart beat out of my chest, and like a bolt of lightning, every neuron in my brain fired up, every nerve in my body wide awake. Every muscle started to feel sore, the burn settling in. “Hey bro, why don’t you look in the mirror?” Zach’s voice boomed behind me. I turned to look at the mirror hanging on the wall, and apart from Zach’s hulked out self idly fondling himself behind me, I could see my eyes glowing through my glasses, a bright piercing green just like Zach’s. For a split second, I was scared. I couldn’t think to be scared for much longer though as a numbing pain quickly took over my head. My body… I felt like I was recovering from the most intense full-body workout of my life. Soon I knew why Zach was moaning, as I suddenly shuddered, a wave of pure pleasure and power rushing through me. Gamma-powered testosterone was pumping through my veins I already felt different. I felt stronger. “Fuck… You’re turning me…” “Into a were-Hulk.” With no shirt on me, I was able to watch my hulkout completely. I kinda began to lose myself; it’s so hard to think when you’re just overwhelmed by all the sensations. I doubled over as I didn’t have the strength to stave off the transformation anymore. I just looked up at the mirror to see my shoulders swell, feeling myself begin to pump up. Biceps. Triceps. Delts. Pecs. Glutes. Calves. Everything. “Fuck… FUUCKK!!!” I roared. I was shaking in pleasure. My muscles were on fire. Everything was growing. My arms were bigger than my head was before. My chest was bigger. My thighs were ready to explode out of my purple shorts hanging onto dear life. And with the shudders in pleasure in my crotch, the ecstasy of my growing cock didn’t help my shorts situation ever. All the while, through the exposed and smeared patches of paint, my skin was getting green too. Shit, my skin turned green. I didn’t realize it until that moment, but green skin seals the deal. There’s something about it — maybe it’s the toxicity. The visual that you’re more than human. That you’re different. Stronger. A monster. It felt almost narcissistic to be so turned on by the sight of my own transformation. I could feel the growth, and that alone was enough to turn me on. But I could also feel my brain get rewired by the transformation. Every chain of inhibition was broken. I wasn’t just stronger. I’m the strongest there ever fuckin was. I’m better than these puny human wannabes. I’m fuckin superior. I’m fuckin savage. I’m built to destroy. That primal beast inside, everything I ever suppressed, was awake. It was here. I was it. And I fucking loved it. “I feel so… STRONG.” I liked the sound of my voice booming in the room. I looked unbelievable. I was undeniably me — my proportions were mine, just adjusted. But I also looked undeniably different. I stood so much taller than I’d ever been, probably just an inch taller than Zach was now. I looked brutal — lean, but muscular; huge, but ripped; angry, but cocky. Veins carrying more gamma-powered blood bulged against my skin. My hair was slick and sticky with sweat just like Zach, but in a slightly lighter shade of green. My glasses fell off my face during the whole ordeal, and I could admire how good I looked in green. And as my eyes settled on my hand absentmindedly beginning to stroke my dick, I only said one thing. “Hulk needs to CUM.” I felt stupid as I said it, but I felt I deserved to be referred to with my title. I looked back at Zach, a wide smirk on my face. Zach mischievously grinned back. “This Hulk also needs to CUM.” Fuck being straight. Zach got up and approached me. I tried to go and pin him down on the bed, my inner dominating instincts kicking in, but instead Zach caught me and pushed me against the wall. I was surprised, but I felt so good I let it happen. I was caught off guard as Zach kissed me again, this time with more strength and tongue, before leaving my lips as he made his way down my neck, then my chest, licking my nipple and eliciting a moan I never knew I could make, then down my abs and to my cock. Zach was somehow able to get my shorts down without destroying them. That might be the most impressive thing. He quickly went to work on me, my dick in his mouth. My toes were curling and my back curving as I could feel his tongue travel my shaft, his lips holding me. Guys really did give better head. He stopped as I was feeling the build up. He rose with a smirk and commanded. “Now Noah sucks.” He had his hand on my head, with just enough pressure holding me down to make sure my mouth took him all the way. I threw in some handiwork, lubed up with my saliva, for good measure. It was when he began to more rhythmically thrust into my mouth and his breathing grew faster that he pulled me away; his eyes half-lidded with rage-filled lust, just like mine. He then took both our dicks in his hand and started jerking us off together. The rhythmic strokes and our loud breathing were interspersed with grunts. Eyes locked as his free hand flexed and mine felt my body and his. “Bro. Fuck. I’m about to. I’m gonna… I’m…” “Me too. Me too. I’m gonna…” With a deep moan from me and a roar from Zach, both our dicks began to spasm. I shuddered and let go and I felt all of my concentrated energy, all the lame human energy I’ve built up, released as I felt the most powerful orgasm of my life, my cum shooting up past my hair, hitting the ceiling of Zach’s room. Zach came not long after, his cum shooting onto both his abs and mine. Shivering from the climax, we both slowly sank to the floor. Half expecting us to revert back, I just sat there, hearing us breathe and feeling the warm cum that was stock on both our skin. But as we stood there, my heartbeat feeling his, and I felt just as energized to seize the night, I knew that I wasn’t turning back any time soon. I looked back at Zach and we both smiled. We had a party to go to. We showed up at the main event after skipping the pregame at Jen’s. Jen was absolutely pissed, but I honestly could not give a fuck. Later in the night Zach and I both won that costume contest and a sweet $100 each. The next morning I woke up in the same bed as Zach. We were both completely naked, our tattered clothes at the foot of his bed. We made some crazy memories last night — me dumping Jen then facefucking some pathetic dude who couldn’t resist handling a real man like me, and Zach fucking Jen. As I held Zach, who in his human form is way less dominant than he is Hulked out, and caressed his shoulder as he laid on my chest, I had to admit that I’d never felt more of a connection with anyone, even Jen. Even when we’re puny, he’s cute. “I can’t wait for the next full moon, babe.” I couldn’t believe it, but I’d fallen hard for my roommate. “Why?” Zach said, snuggling closer to my chest, which was noticeably more muscular than before. “Oh you know why. So we can do all that over again, bro.” I heard a deep chuckle from Zach. I looked down and immediately got boned seeing his eyes having turned a vivid green. “Who said we needed to wait for a full moon?”
