I had just got back from class and was sitting at my computer when I heard and felt the telltale thumping rumble of Ben stomping up the stairs to the third floor. His approach was unmistakable: slow, heavy, resonant plods that shook the whole building. I immediately started to chub up just anticipating his return to the room. I hadn't cum in a week, and I was so horny all the time it practically hurt. My balls were constantly tight, and I had to concentrate to keep from having a boner in class, especially in the human genetics class I had with Ben. Watching him squeeze into one of those tiny desks was hilarious and hot at the same time. I rubbed my aching ball sack and felt my cock swell up as the thumping, rumbling sound of Ben's approach got louder.
I heard a grunt from down the hall as Ben cleared the final steps, and a moment later the behemoth was wedging himself through the doorway and into the room. He had to turn sideways to fit his broad, muscular shoulders through the entrance; he was so thick that his pecs and back were getting to be a bit of a tight fit sideways as well. A wave of Ben's intense body odor slammed into me as he closed the door, sending shivers up my spine. Another wave of it hit me as he peeled of his skin-tight, sweat-soaked tank top and threw it onto the pile at the end of his bed. It was one of the few that still fit him, and it didn't look like it was going to last much longer.
He reached for his gym bag and pulled out four protein shakes he had tucked away and proceeded to drink all four of them in rapid succession without saying a word to me. He was looking absolutely swole; every part of his body was turgid with rock-hard muscle. His bicep bulged thick and round as he guzzled the last shake into his mouth; he had just downed at least 120 grams of protein in two minutes, and I knew that was but a fraction of his normal daily intake. His chest was ruddy and pumped up, his nipples thick and hard. His neck merged with his shoulders and traps as he shrugged and stretched his head from side to side, popping and stretching the muscles. He finally turned to acknowledge me, and I saw his massive cock bulging in his boxer briefs wedged between two thighs which were each clearly bigger around than my waist. I knew it was time for me to make him grow.
He eyed me and stared down at my own sizable bulge in my shorts, begging to be set free and release the load I had been building up for a week. Ben waddled over to me, the stomps of his strides shaking the room and rattling the window panes, and he towered over me. My mouth dropped open as I saw up-close just how massive he was. I had never seen him so pumped and swollen from the gym. His enormous bulge was right in face as he stared down at me, throbbing and pungent with ball sweat. It was clear he was ready for the next level. He reached down and tore off my shorts in one clean motion with a meaty paw, my pants ripping down the middle like it was tissue paper. My cock sprung free.
"Time to grow," he rumbled, and in one smooth motion he bent down, grabbed me with his beefy hands under my armpits, and effortlessly lifted me into the air. He lifted me all the way until my head bumped the ceiling. It looked like it was hardly any effort for him to lift my 180lbs as high as he could and hold me there. A fresh wave of his man stench filled the room as his uncovered armpits were exposed to the air. They were hairy and damp with sweat; in fact his whole body was slick with jock sweat.
He took my entire rock-hard cock into his mouth and started sucking powerfully, a hard, rough, vacuum-powerful force that was design to extract his own personal muscle-growing juice. Considering I had been waiting a week for this moment, I held on longer than I expected, just long enough for me to look down and admire the giant-to-be effortlessly holding me 3 feet in the air. His traps and shoulders swelled up in heaving mountains of muscle; thick, massive, powerful. His neck bulged out and the folds on the back of his head bunched. His triceps ballooned the longer he held me. He stared up at me with a hungry look in his eyes, grinning that arrogant smirk I had seen so often since the semester started.
Removing his mouth from my cock briefly, he roared "Come!" and opened his maw to receive my seed; it was an order, not a request. I exploded with a moan as thick ropes of cream blasted into his mouth and caught on his beard. I shot one, two, five, 10 thick spurts of it until I was finally spent, my balls tingling with pleasure as they finally had release for the first time in days, my cock exhausted and sore as Ben clamped his lips around it and drained every drop. He was growling happily as he guzzled down every drop, chugging the cream as it spurted from my mouth. After getting every ounce from the source, he licked his lips and wiped up all the excess that had dripped onto his beard and chest, his shelf-like pecs catching any of my growth-inducing spunk from hitting the floor. He was like a bear licking up honey, but it was no ordinary honey.
Ben finally put me down, showing no signs of fatigue, and chuckled happily, a low, rumbling bass. He waddled to the full-length mirror on the back of the door and started flexing.
"Fuck yeah, looking huge," he said, lost in a reverie of worshiping his own massive body. He hefted his massive right pec, causing his unbelievably thick forearms and biceps to bulge and bunch up, fighting for space. He pinched his nipple and growled with pleasure, and I saw his chest swell bigger. He took a deep breath and watched his musclegut balloon larger, and he groaned as he exhaled but saw his massive boulder gut remain swollen and hard.
"Fuck yeah, bigger, bigger," he huffed as his breathing quickened. He pinched both of his hard nipples, twisting and teasing them, and his chest swelled bigger with thick muscle as he growled with pleasure. He flexed his traps and shoulders and I heard the muscles crunch and pop as they merged with his thick neck. He spread his chest and lats to the side and he grew a half a foot wider. His massive shoulders bulged out, thicker and round with muscle. He looked at his expanding form in the mirror and boomed with laughter and quickly threw up both arms in a massive double-bicep flex. Each arm exploded with size, the peaks round and solid like cannonballs. Ben was wet with sweat again as he stared at himself in the mirror, watching himself grow wider than the doorway and edging higher as he grew taller. "Bigger, stronger, more," he grunted, his voice loud and deep. He willed himself bigger and bigger, flexing his tree trunk thighs, each one expanding thicker and rounder. The muscle spilled over his knees in an excessive display of power. His calves were way bigger than my thighs when he was done tensing and flexing them, grunting and sweating all the while.
"Oooh shit!" he rumbled, and suddenly let loose one last blast of growth that caused every part of his body to explode with size. He shot two more inches taller and he swelled thicker and wider than ever. He looked totally swollen and bloated with beefy muscle. Finally done, he smirked back at me and motioned for me to follow him to the bathroom and the scale. First he had to get through the doorway, which was suddenly an obstacle. He turned all the way sideways and tried to suck in his musclegut, but it was his hairy chest and thick jock bubble butt that rubbed against the door frame. He wiggled through the door and popped out into the hall and started plodding to the bathroom down the hall. His footfalls really did shake the floor now, and he grinned as he felt how much heavier he was than before.
As he stepped onto the scale, Ben knew he had surpassed his greatest expectations.
"Matt, get down there and tell me how fucking huge I am," he commanded, clenching his fist and flexing his massive bicep and chest in a display of power he knew I would appreciate. He was unable to peer over his enormous chest any longer, instead he flexed his barrel chest outward and rested his square jaw on his pec; he had always wanted to do that, and now he was big enough. His short, dark beard mixed with the thick chest hair and he rumbled his approval.
My jaw dropped as the number resolved itself on the scale. I knew storing up a week's worth of cum would work well, but this was insane.
"Well bud, how fucking huge am I?" Ben boomed from above me, admiring his own huge tricep as he swelled his massive gut above me.
"Ben, you just grew over 40 pounds. You weigh 405 pounds now and probably grew 3 inches. You're a fucking monster. I've never seen anyone like you. You are becoming a giant," I gushed, unable to contain my lust for him. "May I service you?" I implored, and Ben grunted his approval. It was the least he could to repay me for the growth-inducing seed I had saved up for him.
I pulled down his pants and his monstrous, bulbous cock swung out and hit me in the face. Its' weight and power was tremendous, and I knew it wasn't quite 100% hard yet. The jock stench emanating from his crotch was more powerful than anything I had smelled yet; sweat, cum, BO, power, sweat. I hefted his balls; they were goddamn heavy. I ran my fingers over the tight sack and Ben grunted with lust. I looked up and saw his great gut swelling out above me, bested only by his enormous barrel chest and hairy, thick, round pecs, each one capped with a hard nipple. Ben started pinching his nipples and boomed "Suck that cock." He was a total authority in complete control.
His cock was longer than my hand and thicker than my wrist. It made the meaty brats I ate growing up look like mini hot dogs. It was topped by a bulbous mushroom head that swelled out from the rest of his cock, bright red . His piss slit was already leaking copious amounts of pre-cum, which I started licking up greedily. I opened wide and started sucking his massive cock, gently using my teeth to add extra friction on the way down and then pressing my lips down on the rock-hard monster as hard as I could on the way up. I deep-throated him and choked as I tried to fit as much of it down my throat, getting only about 3/4 the way in before I had to stop. He growled with pleasure and his breathing increased.
"Faster, more," he groaned from above, and he put his heavy right hand on the back of my head, pushing his cock deeper in my mouth. He was already pretty close to cumming if his heavy breathing and growling sighs were any indication. Without warning he roared with power and exploded down my throat, a thick, hot jet of cream that I had to struggle to drink fast enough. He went for almost as long as I did in the room (he had cum this morning, I had stored up for a week) and finally finished with a satisfied growl.
I stood up and looked up at the giant football player towering over me. He was the biggest person I had ever seen, easily twice as wide as I was.
I suddenly felt a rush of heat in my abdomen, and I bent over double. What the fuck was this feeling? I felt burning inside, and I suddenly was compelled to flex as much as I could. I was shocked to realize that I was growing a bit bigger after taking in his cum as well! My modest torso swelled with new power and my thick legs hardened and bulged into bigger muscles. I jumped up an inch in height and, stepping onto the scale, i found I had gained 10 pounds.
"Excellent," Ben thundered from behind me as he towered over me. "Now you can continue to be big enough to service me as I grow even bigger. I'm going to need more and more of your cream in order to be even HUGER, STRONGER, and more MASSIVE than I am now!" Ben boomed, punctuating his statement with a laugh that shook my bones. He wrapped his huge arms around me and squeezed, forcing the breath out of my lungs and making me feel tiny even though I had just grown. There was no questioning his mass and power.
Ben took one last satisfied look at his gigantic frame in the bathroom mirror. He swatted his gut and bounced his massive chest, flexed his huge biceps, and rolled his mountainous shoulders in turn. "Let's go see if any of my fucking rags fit anymore and get some food. I'm fucking STARVING!" he said, his deep, resonant voice echoing off the walls of the bathroom, which now seemed tiny with his massive frame filling it up.
I admired the extra bulk to my body and followed him out of the bathroom obediently. I couldn't wait for him to get even bigger.

Chapter 4
I woke up as the light from the window hit my face. It was a Saturday, and we had a big game later that afternoon. I felt great, still energized by drinking Ben's cum in the bathroom a couple weeks back. Ben realized after that that he needed to save every bit of growth-inducing cum for himself, so he had only let me feed on his massive cock once since then. It was such potent stuff that I didn't need much. I sat up in bed and appreciated the extra pounds and inches on my body, especially my legs, which would come in handy on the field as a kicker. I looked across the room at the massive beast in the other bed and instantly felt tiny again; it looked like a boulder of muscle under a white sheet.
I quietly got up and walked over to Ben's sleeping form. He was snoring loudly, the bassy vibrations filling the room. It seemed every time I saw him, he was bigger...his massive frame overflowed the pathetic twin bed he had to sleep on, and the mattress and frame strained under the pressure of his 420lb weight. Since I saved up my spunk and he swelled in growth last time, he decided not to wait between sessions and just milk me for all the cum I could give him. I was more than happy to oblige. As part of that decision, I got to the edge of the bed and dropped my boxers, revealing my already rock-hard cock.
I slapped his face with my cock to rouse the great behemoth. He growled, turned towards the edge of the bed, and opened his eyes.
"Feeding time," I said, as I offered my cock up to his waiting mouth. He growled, enveloped my entire shaft, and started sucking with the force of a vacuum. I always woke up with morning wood, and being this close to him was enough to set me off, so I was already on the verge of shooting; once I felt his powerful tongue pressing against my cock, willing the cum out of me, I didn't last long. I looked down at his massive neck, traps, delts, and shoulders, which merged together to form some freaky muscle supercomplex on the top of his torso. He saw me looking and shrugged slightly. That was all it took for the muscle to explode and swell before my eyes. I thought about how those muscles would soon be bigger after he guzzled my cum and I erupted into his mouth. My libido and amount of cum I shot had multiplied since drinking Ben's supercum, and Ben chugged down everything I could give. I shuttered as I shot jet after jet into his mouth and I thought about Ben growing even bigger. He licked up every drop before rolling up to a sitting position in bed, causing the frame to squeal in protest. He sat on the edge and then stood up, towering over me at 6'9" and 420lbs. He was twice as wide as me and almost a foot taller.
"Thanks bitch," he boomed as he looked down at me with a cocky smirk on his face. He bounced me out of the way with his rock-hard gut and stomped over to the fridge, totally naked. "Gotta get ready for the fucking game today, gonna CRUSH those motherfuckers," he said as he tore the cap off one of his protein shakes and downed it.
Before he had a chance to finish, I blurted the question that had been on my mind the last few days: "Hey, are you going to tell me when you're going to grow big time again? It's been a week of three-times-a-day feeding and you've 'only' gained 5 pounds. What's going on?" I figured I deserved at least an explanation for all the exemplary service I was providing.
Ben just chuckled and said "You'll see," after he finished chugging his shake. He scratched his balls and rubbed his half-hard cock as he squeezed through the doorway to head down to the bathroom.
---
Ben stepped up to the line of scrimmage as the opposing team, Ohio State, got ready for their 3th down try. It was halfway through the third quarter, and us Gophers were up, but only by 3. Ben was the biggest player on the field by far, and he was consistantly demanding a double-team of Ohio's biggest offensive linemen to even slow him down. All the plays were running as far away from him as possible, of course, and I could see that Ben was getting frustrated by the cowardice of these punks.
The ball was snapped, and Ben charged forward, his massive shoulders bearing down to bowl over whoever was in his way. He was met this time by a triple-team, all of them holding and grabbing but Ben didn't get any calls from the ref...he was so big, it was hard for the refs to officiate him. Ohio couldn't get the ball past the first down marker, but were mere inches away, so they were going to go for it on the 4th down. They called a time out to set up the play, and Ben and the rest of the defense jogged over to the sideline.
Instead of meeting with the coaches though, Ben stomped over to me. I could see he was furious. A cloud of football sweat stench hit me as he stood close. He pulled of his massive helmet (it seemed bigger than my torso sometimes) and roared.
"This is such fucking bullshit! I'm tired of theses weaklings getting in my way. They're too fucking scared to take me one-on-one, I should be crushing them!" he said, steam pouring off his close-cropped head and bull neck into the cool Minnesota fall air. "It's time I unleash the beast."
"What the hell are you talking about?" I asked him.
"You know that thing you asked about this morning?" he said, taking a step back and standing tall, showing off his massive bulk. "Let's just say you're about to get your answer," he said with a smirk, and he flexed his big shoulders and smacked his musclegut. The whistle blew and he shoved his helmet back on and ran back onto the field. What was he going to do?
I got my answer as soon as he got down into his stance on the line, squatting low. I could see it from the sidelines...he was growing! He had been saving up all the growth energy from a week's worth of my seed into his massive frame and was tapping into that incredible power now.
I could hear his deep growl from the sidelines as he swelled bigger and taller than anyone else on the line, making them look like pop warner players as he grew even larger. The ball was snapped and he rushed forward. The triple-team came as Ohio tried to ram the fullback up the middle to get the last yard they needed, but Ben, who was exploding with new strength and size as he blew past 450lbs, bowled all four of them over like they were cardboard cutouts. He drove his massive shoulder into the fullback's chest, sending him flying back 10 feet. He landed hard on him, and felt bones break.
The crowd cheered as we got the ball back, and Ben stood up from the carnage he had produced. He rose taller than ever and roared as he grew even larger, muscle cum and testosterone coursing through his veins. His massive shoulder pads cracked in half as his chest and shoulders swelled bigger, and the "M" on his Minnesota jersey tore right down the middle. His weighty pectorals demanded space to grow even more. His biceps drew tight on the jersey and split through the mesh material as he flexed over his vanquished foes, who suddenly looked tiny next to this juggernaut. He growled as he felt his body growing bigger and heavier, feeling like a giant among children. The skin-tight material of Ben's leg pads ripped as his thighs swelled larger, and his cleats sunk deeper into the turf as he hit 475lbs of football-playing beef.
Gripping it with both hands, Ben cracked off his now too-tight helmet easily and laughed as he continued to grow, swelling taller and heavier than ever before. His gut swelled out, rock-hard and ponderous, and he expanded wider. He threw aside his shoulder pads, which were no longer really necessary on his massive, impenetrable frame of rock-hard muscle, and flexed again, bursting with new size as he hit 500lbs and 7 feet tall. His shoulders spread to a new width as they bulged with more muscle, and his neck disappeared as his growing muscles fought for space. Another beefy neck roll formed on the back of his head as he grew thicker. He swelled out his chest, the massive, heavy pecs hanging over his boulder gut teeming with beast strength, and growled as he finally finished growing, leaving the rest of players on the field looking like pathetic weaklings next to him.
Ben looked down at the puny offensive linemen and fullback he had crushed a moment ago, a combined weight of over 1000lbs, and laughed at how fully he had dominated them with his new power. He leaned down and flexed his bicep in their faces, bigger than ever, and yelled "Don't fuck with the juggernaut, bitches!" His arm swelled, a massive rock-hard mountain of muscle and power, and the other players could only cower and stare in awe at the giant standing over them.
Ben stomped off the field and headed back towards me. He seemed to grow even bigger as he got closer to me, and as he got close and stood inches from me, I neary came in my gear. He was fucking gigantic. He looked down at me, and said, "Fuck, you are tiny now," and chuckled in an arrogant, brutish manner. "Felt so good busting out of my gear like that, and they had to special order that shit for me!" he boomed, his deep laughter rumbling through me. He towered over me and looked down over his massive chest to see me. His musky scent was sharp and overpowering, and made me feel light-headed. "I'm glad I saved up all the cum for that, it felt great. I can't wait to see what this body can do...and I can't wait to get even BIGGER!" he boomed as he walked past me and headed to the locker room, steaming as the heat of his growth warmed the cool air. I looked down and saw his massive footprints in the ground; the grass was matted down and the dirt was sunk almost an inch down under the weight of the 510lb football-playing monster. My own foot looked like a child's next to them. I could easily imagine these giant footprints looking even bigger and crushing into concrete or tile if Ben kept this up.
___-
headed back to the dorms after the game was over. I hadn't seen Ben since his explosive on-field growth spurt, but everybody was talking about him. At this point it was pretty hard to deny that Ben was growing at an extraordinary rate and turning into a freak; guys on the team had been whispering about it all season, but no one had dared question Ben about it. After the game, coach told everybody to forget about what they saw, and said there would be an investigation into what was going on with Ben. I knew Ben wouldn't give a shit whether he was kicked off the football team or not. I knew all he cared about anymore was growing.
As I approached my room in the dorm, i was hit by an overpowering stench of football jock BO. It was Ben's stink, and it had only grown more potent since his latest growth spurt. It was sharp, musky, and funky, and it permeated the entire floor of the building. I was stunned to see the door and door frame had been ripped out of the wall and strewn into the hallway. There was rubble from destroyed concrete in the doorway, and massive chunks of wall taken out of the sides of the entrance by what looked like fist-sized impacts. I stepped through the suddenly-larger entrance and saw Ben standing naked in the middle of the room, his back to me. He was still drenched in sweat and huffing in great heaving breaths. He was absolutely gigantic; his massive frame seemed to fill the entire room, and his head loomed dangerously close to the ceiling. He had grown even more than when he was on the field. A pile of his broken football gear lay in the middle of the room, drenched in his jock sweat. He turned as he heard my tentative footsteps enter the room.
"AHHH, there you are!" he said, his voice sounding deeper and louder than before. He crossed the room and stood in front of me. My eyes were level with the top of his round, hard belly, and the top of my head with the hard, protruding nipples that crowned his thick muscle tits. He looked down at me and boomed, "damn, you are fucking tiny now! Standing next to a little shit like you makes me feel even BIGGER!" He proceeded to roll his bloated pecs in my face, the hair bristling against my face as they swelled out.
"MMMMPH, feel the power in those motherfuckers. So thick I had to tear the door apart to even get into the room. Tearing off the door was surprisingly easy, and it felt so good to punch the shit out of those fucking walls," Ben rumbled; the depth and volume of his voice made my chest cavity vibrate like the bass at a rock concert. He clenched his fist and held it up to me, his massive arms swelling with thick muscle. His huge fist looked as big as my head. "I couldn't even squeeze into the room ducking and sideways, so I made the entrance BEN-SIZED! It was fucking easy, this babies crushed through that wall like it was paper! In fact, I think it could stand to be even a little wider..."
Ben stomped past me, his hard gut almost bowling me over. His shoulders were indeed still too broad for the doorway. He was so immense, everything else around him suddenly looked like a miniature version of itself. He great huffing breaths made him swell and bulge; it almost looked like he was constantly growing bigger all the time.
He managed to squeeze his yard-wide shoulders into the tiny door frame, concrete already tearing away, yeilding to the big man's hard wide bulk. Ben got down in a squat and stuck his head through the other side of the door, into the hall. He stood as much as he could in the doorway, his boulder shoulders scraping more of the walls away. Ben took up the entire doorway with his mammoth bulk, his shoulders pressed hard against the sides, his traps and beefy, multi-rolled neck squeezing against the top of the 7-foot doorway, and his tree trunk legs filling the rest of the empty space, swelling and tensing in anticipation.
Ben grunted as he pressed upward with all of his considerable power, and the wall above the door immediately cracked down the middle. I could hear wood, plaster, and drywall cracking and crumbling as the wall suddenly gave way and a cluster of wall fell down upon Ben's mile-wide back. "OOOOH YEAH MOTHERFUCKER, THAT'S WHAT I'M TALKING ABOUT!!!" Ben roared. Ben stood to his full height, his spiky hair nearly grazing the 8-foot ceiling. He adjusted his stance, the room shaking with his heavy footfalls, and he started pushing his wide shoulders and beefy arms against the side. The walls cracked and crumbled like the ones before, Ben grunting and huffing with effort. His triceps swelled out from his arms as he pushed even harder, and the massive chunks of wall gave way on each side. He was literally molding the doorway to fit his massive frame. The shape of the doorway was no longer a rectangle; instead it was the shape of a giant, wide, huge man. It looked like one of those cartoons where the outline of a character is left in the wall, only it was for real, and it was crushed out by Ben's awesome power.
"FUCK YEAH BITCH! FUCKING DESTROYED THAT WALL!" Ben bellowed as he turned around and admired his destructive work. He sauntered through the doorway and back into our room, still having to duck his head down a bit to fit through. He rose to his full height again and smirked down at me. "How'd you like that, runt? You like seeing my power? All this fucking muscle?" He bounced his huge pecs in my face again and tensed every muscle on his torso, making his entire frame swell. A new wave of his stink slammed into me as he lifted his massive thick arms and flexed, his hairy pits right in front of my face. I was frozen in place, my mouth hanging open at the sight of Ben's insanely thick arms.
"Go on bitch, lick these fucking biceps. I swear each of my arms feels like 100lb each." I went to town worshipping his arms. They were so thick, bigger than my head easily, and hard as granite. Trying to push against his rock-hard biceps was hurting my fingers, which looked frail and tiny next to his massive powerful bulk. His forearms were veiny and hard, easily bigger than my upper arms; hell, probably bigger than my legs. I moved to his deep, hairy armpits, licking up the salty jock sweat and taking deep breaths of his rank masculine stink.
"Mmm, yeah you like my stink, don't you? I kept fucking growing all the way back from the game. I weighed myself when I got back--I had to resize the bathroom doorway too, heh" Ben chuckled, a deep, cocky, grunting sound. "Five-hundred and fifty fucking pounds. 550. Do you realize how heavy that is? How fucking enormous I am now?" he boomed down at me, his hot, sweaty body swelling against mine as he talked about his massive bulk. "No wonder those pussies on Ohio State crumbled and broke under me. I could fuckin crush you or any man effortlessly."
Ben demonstrated this by wrapping his impossibly huge arms around me and squeezed hard in a bear hug, lifting me off the ground like a flimsy pillow. Then he wrapped his beefy right arm around my head and squeezed me into a headlock. I immediately started to feel consciousness slip away, but mercifully he let me go.
"I ain't gonna hurt you though, little one," Ben said down to me. He ripped the pants off my body and effortlessly lifted me up, his muscles barely even tensing as he hefted my 200lbs. "I'm just gonna fuck you." I looked down and noticed his massive, raging hard on, a foot long and as thick as my forearm. He threw me across the room onto his bed and slowly stomped over to me, each step like an earthquake. His arms swung wide to the his sides; his shoulders and lats were so broad that even at his height, he seemed almost as wide as he was tall. Each massive leg, as big around as my waist and half that again, rolled over and rubbed against each the other one as he sauntered over to me.
"Looks like you got a sweet, tight ass for me there, boy" he said, his eyes glazing over with lust as he looked at my tight jock bubble butt. "Gotta cum so bad. So horned up after growing bigger. I wanna fill your hole up good and make you bigger so you can feed me even more of your hot cum. GOTTA GET BIGGER!!!" Ben boomed as he towered over me and licked two of his thick fingers. He was gonna loosen my tight, waiting ass first before he fucked me.
He reached down and slammed his bratwurst fingers into my ass, and I felt firey ecstacy shoot through my body. He stretched his fingers around and pushed deeper, growling and looking right into my eyes. His massive cock oozed precum and pulsed with anticipation; it looked just as thick and powerful as the rest of his giant body.
"Feel good little one? You gonna take my monster cock?" He hefted his massive unit, the whole thing looking like it weighed about 25 pounds. He finished loosening me up by lifting my entire body off the bed with one hand effortlessly, his fingers buried deep in my ass, stretching me out good. I moaned my approval and he held me up with one arm. He slipped his fingers out of my ass but continued to hold me, and slowly lowered my ass towards his cock.
He slicked up my hairy hole with spurts of precum that trickled out of his cock. I felt the massive engorged head press against me as he lowered me, in total control, and he growled with pleasure as he entered me. 550lb of giant college football player started fucking me hard, great powerful thrusts that slammed into me like a freight train. I fell over onto the bed, his massive tool impaling me, and I held onto the mattress to brace myself against the power of Big Ben.
"FUCK YEAH, you got such a tight fucking ass, better than any chick I fucked, I aint gonna last long at this rate," Ben roared, grunting with each powerful thrust and growling with pleasure. He leaned into me and I could feel his huge gut and pecs pressing against my tiny back, coating me with jock sweat. His short beard bristled against my neck and I felt his hot breath on the back of my head. He smelled like protein shakes. I clenched down on his thick cock with all I could, and could feel his mushroom head rake across my prostate even more, sending shivers of pleasure up my spine.
"MMMMMMMPH, FUCK YEAH I'M GONNA CUM," Ben bellowed as he bucked me furiously, my ass stretching to the limit as each thrust felt more and more powerful. He was sweating like he had just run a marathon and every muscle in his body was swollen and pumped. He growled and roared as he erupted into my hole, filling me up with an overwhelming amount of his seed. I immediately began to grow with more muscle and size, bulking and swelling underneath him as he continued to pump his muscle cream into me. I growled with ecstacy as I felt my hanging pecs swell with heavy power and my sturdy arms bulk up. My ass and already thick legs bunched up with new muscle, my hole tightening even more around Ben's massive cock, sending a shockwave of pleasure up his body and making him cum even more. I felt my body lengthen and tighten as Ben pounded into me the last time, and he pulled his red, swollen cock out.
I lay there for a moment panting for breath and making sure my ass was in one piece. "Damn boy, you grew fuckin' good!" Ben grunted down at me as he rubbed a big paw across my wider, more muscular back and firm bubble butt. "Mmmph fuck yeah, you got such a nice ass for me to fuck." He slapped my ass and squeezed the round muscular spheres in his massive hands. He fingered up some of his cum that was trickeling down my leg and slurped it up.
I turned around and got up, testing my new bigger size. I was built more like a linebacker than a kicker now I realized with delight, and I bounced my newly thick pecs and flexed my dispropotionately huge legs. I noticed my engorged cock swelling with new size, and thought of a great present for Ben.
"I think I can return the favor, big guy," I said with a cheeky grin, and he growled down at me from his seven and a half foot tall vantage point. He reached down and put his fingers up my ass, effortlessly lifting me again. He lifted me so my long, throbbing cock was even with his mouth, and he wrapped his lips around it. His thick, powerful tongue pressed against my rock-hard cock and I came immediately, feeding the moster more growth-inducing cum. I came more than I ever had before, thick ropes of cum from a thick 250lb linebacker build instead of a 200lb kicker.
He dropped me onto the bed when I was spent, and immediately began to grow even bigger. I didn't think it was possible for him to get any thicker, but he did as he chest swelled wider and bigger. He roared and flexed his arms and his entire body burst with more muscle and power. His head finally hit the ceiling as he swelled out his power gut and bulged his thighs and calves even bigger. I heard crunching and popping sounds as his body reshaped to handle the massive weight and awesome power of his bulk. His huge cock, still leaking cum and swollen from fucking me, lengthened and thickened with the rest of his body. Ben shrugged his titantic shoulders and his traps and delts bulged up higher, merging with his thick neck. He huffed for air, his massive sweaty chest swelling and bulging.
"FUCK YEAH!" Ben growled as he flexed one last time, sending a final shockwave of growth through his giant frame. "SO MUCH FUCKING BIGGER THAN I WAS THIS MORNING! AND IT'S ONLY UP FROM HERE!" he bellowed and rubbed his bullet nipples and felt the weight of his pecs, his arms swelling to new thickness. Ben wasn't done growing yet by a long shot.
