Grandpa Burt Grows 2(musc)
by muscl4life and Rdalrt2
I still couldn't believe that my grandpa, my hero former cop grandfather Burt turned into a monstrous muscle freak because of the formula I invented. Still, he spent the previous night proving me that he was all so real, and I must say that I wasn't expecting that he could be so intense. We had been fucking for so many hours that I have simply lost track time, as well as the sensibility of my boy hole, which had been used and abused by my glorious grandpa as it pleased him.
After trashing his bedroom for – oh so many amazing hours – Grandpa squeezed into the tiny doorframe of his en suite bathroom and gently tried to insert his monumental mass into the huge bath tub, which he only partially have succeeded, so he had to hold me over the tub while most of his ginormous physique was still outside, which was just fine since he wasn't interested in soaking his glorious monstrosity in the water just yet, he just wanted to check how much of his cum actually fit inside me.
Grandpa actually seemed very interested in how much of him could actually fit in my tiny body, after all his cock had to be at least 15 inches long and so damn thick that it was a real miracle that he didn't split me in half with that monster. Still, he took great deals of pleasure by sticking his fingers and the giant muscle cock of his into me like I was just his boy toy, and I loved the way it made me feel so tiny and pleasing for the glorious geezer.
"Oh grandpa..." I moaned as he retrieved his giant member and watched the uncanny amount of his cum going down the drain as he held me over the bath tub.
The massive muscle monster held me, his only grandson tightly as he turned the water on, squeezing my little frame against his incredible mass as the shower washed over our bodies.
I've never felt so small and so precious at the same time, I was just a little puny bug compared to my humongous, massive grandpa, who seemed to be growing constantly! He was so horny and insatiable, putting much younger porn stars to shame, and he was hung like an elephant!
"Mmm, damn boy, your ass tastes amazing, I could eat it for days!"
I giggled. "Well daddy, no one doubts you could do that, I just never thought you would keep going and going, and going. Geesh, you have fucked me so many times already, your bedroom is a freaking sea of sweaty muscle cum."
I blushed as the ginormous freak gently washed my boy butt, massaging the soft areas with his huge fingers and just making sure that I could still house the immense cockhead on him.
"Did you get soft any moment ever since you grew grandpa? I mean, not that I am complaining it is, well to realize you are THAT manly, makes me feel weak, after all I am only 19 and my cock already is aching just to even think you are using me like that, I'm totally spend and I'm just a teenager, I should keep up with your horniness right?"
The huge man laughed, rubbing the base of his massive, hard cock. "Actually I think it's just getting harder! All that testosterone surging through me is keeping me so turned on, my nipples are hard as diamonds, my cockhead is so sensitive. Even just talking about it making me hornier than ever!"
Although I didn't mean to feel uncomfortable, it was just something that I hadn't anticipated.
"Grandpa, you are so much more than I could ever take, I mean...you have fucked me until I passed out at least 4 times and you've kept going on, you are so much more than I could ever try to encompass. Oh grandpa, you need so much more for your pleasure right? Oh I'm so stupid, so selfish; I have been thinking on just me when it's you who need so much more. Grandpa you are still so very horny, we have to find you release right? You want to keep fucking and showing your amazing muscles, oh how could I be so selfish?"
I gently whispered in his ears.
"Please, Grandpa tell me that you want to have more little guys to fuck, I feel kinky just to imagine that I am not even close from pleasing your needs! It makes me feel proud of your humongous size and manliness, I will gladly help you to get all the release you need Grandpa Burt!"
The massive older man blushed, but he couldn't deny his manly urges.
"It's true, boy. I'm sorry, your cherry is so nice and tight but you're not enough for me. You're not NEARLY enough for me. I need more little boys like you that I can wear out, that I can fuck until they pass out, and they won't be able to satisfy me either! I'm too much man for anyone; you are just too weak to handle all of me."
That moment was so intensely powerful, I didn't expect to cum while Grandpa held me like that, but it was just the purest form of flattering. Grandpa Burt smiled as he kissed my forehead, his hard cock ached for more action and I had to provide it.
"You know, sir, we must have to find new ways to release you, we already know you can fuck for hours, but how about working out? You seem to enjoy all that work out, do you feel like it could help you with your enormous problem? I mean we can try to find you some really huge and heavy equipment to give you some challenge."
Grandpa Burt grinned, pondering what exactly could challenge him, but he remembered there was a scrap yard not too far from here. Old rusted out cars and other junk would be perfect for him.
"Mmm, I suppose I should try and work out while I still can, before I grow even larger from more pills." He chuckled, toweling off his naked body as he held me like the precious boy I was to his glorious monstrousness.
"I don't even think we have any clothes that would fit me, and who would dare to tell me I couldn't walk around naked?
"Oh, yeah, that would be a slight problem…"
The first problem we noticed right away was the uncanny width of Grandpa's new muscle. We just stood there measuring him for any kind of possible clothing, but it soon proved impossible.
"We can try to cover your crotch with some kind stretch fabric, in some poser trunk version but a million times bigger!" I chuckled as we tried to wrap sheets around his waist, which still seemed small enough compared to his monstrous chest, shoulders, legs and especially the super mighty cock.
"Please grandpa...can't you take it under three yards? It would make things easier; we still need to figure a way to get you out of the house without destroying the frontal walls.
"Hmph, who says we need to save the walls? If a building isn't big enough for me, I have the right to destroy it. In fact, I've wanted to remodel this old house for a long time!"
He chuckled, tossing his makeshift toga aside as he strode through the hallway, his immense body shaking the floor with every booming step.
"It all feels like a dollhouse to me." He smirked, looking around before staring back at me, those icy blue eyes piercing through my soul like warm knife through butter.
"So where did you hide the rest of the bottles, son? Be honest, you know you can't lie to me." He was shocked, he'd never even told his grandpa he intended on doing more than one bottle, but Burt's police intuition was razor-sharp!
"Oh, Grandpa, I didn't hide anything, I just need to make new batches, I thought that bottle would last for a month, but that's okay. I'll make an even more powerful batch tomorrow, I mean I could go right now back ChemTech but I thought you would like me to...enjoy your new size. I mean there's so much I would like to investigate, your monstrous new size, and your amazing height growth, I didn't plan on that in the original formula, not to mention that you are twice wider than you are tall, which means your muscular proportions are out of this world, I just want to explore your current amazingness before I make you bigger, please sir..." I asked him with my own big puppy eyes.
Burt smiled and looked down at his grandson over his massive pecs. "You want to enjoy my body, boy?...I don't think you're capable of understanding just how powerful I am. Try to imagine how much I can curl with these biceps..." He raised his arms to flex, grinning confidently as the twin peaks of muscle rose up above his fists, above his head, huger than ever!
"Nope, I am even stronger than you imagine, I could lift the whole house up with these arms! And my pecs are so huge and strong, feel how hairy they are, boy. I'm getting furry like a bear, and as my testosterone increases I'll just get even muskier, too. Soon I'll be able to make you cum just from letting out my man-stink."
"I...don't doubt it, Grandpa, but I think we can find a way to challenge your glorious body. We could go to that demolition site near the docks that you've mentioned . They have all kinds of huge old things that you could lift, it would be a great camp study of your monstrous muscles, besides, if we find something that challenges you I can think on ways to increase your muscular density, to make you pack MORE muscle into your body allowing you to get even stronger with hyper dense muscle fibers. You see, sir, I want you to become even more monstrous but in ways that you will have lots of fun!"
I watched as my immense Grandfather seemed even more pumped up with the idea of getting of the house, showing his immense body to the world, at least that would give me some time to think on new improvements to the formula, because I know he would get back to that issue, I knew that Grandpa Burt would never let go of the idea of getting more pills.
"Let me get the door for you, Grandpa..." I offered to open the door, but then I felt his humongous hand pushing me aside so very gently. The enormous older man just had an evil grin in his manly face, and I just gulped in excitement as Grandpa decided it was time to leave his house for a "walk in the park" with me.
He strode toward the front door, despite the fact that he was three times wider than the doorframe. He had no intention of opening it, he just clenched his fists and ducked his head as he barreled right through it, crashing through the wall and taking out an entire side of the house, just laughing as his immense body crashed through! He dusted himself off, his hairy body not even scratched from the incredible sight, looking back at his grandson. "Well, aren't you coming, along boy?"
It took me a few moments to realize the behemoth was actually talking to my little person, so I dusted myself from all the destruction and ran to his side, right away the monumental geezer picked me in his arms.
"Grandpa, I can walk by myself you know?" It was then I realized that things really have changed between us. The way he carried me in his monumental manly massive chest indicated that I wasn't supposed to do anything unless thinking on ways to make him grow more muscular, and even if I wasn't smart enough to conclude that, Grandpa Burt had all reason to voice it out to me.
"You will never walk anywhere on your own unless I tell you to, do you understand boy? Your only job now is to be a beautiful butt for me to fuck, and a brain to come up with ways to make me even bigger. I will carry you everywhere, you will be with me all the time, even when you pass out from my fucking you I will not stop, I will always carry you my precious little grandson. But things still need to get done around the house, so I'm going to go show those weak little construction workers who a real man is."
Burt chuckled, his aged face wearing a smile that was a bit patronizing, but I could see the manly love in his expression, he was digging to have me all for his pleasure, and I guess I couldn't complain much either.
I realized it was not the time to question the prudence neither the practicality of my Grandfather's decisions, so I just played along, enjoying the way in which his glorious muscles waddled. He just covered the distance with his immense physique much faster than I anticipated; we approached the demolition site where they would put down the old industrial plant to build something new.
There were a few big sturdy workers hanging by the door, and Grandpa Burt just walked to them. The glorious muscle geezer chuckled as the 6'2" tall 240 pounds muscle guy just gasped at the size of my humongous grandfather. He dropped his cup of coffee and could barely mutter a word. The other guy, a 6'3" 260 pounds dark skinned man just looked up at Grandpa and gagged.
"Daaaamn!" I guess Grandpa felt happy with their behavior because his hard cock just produced a humongous dollop of precum that he shoot over 20 feet in air before landing loudly between the two shocked little construction guards.
"Hmph, they let you two little weaklings stand out front? Are you sure you're old enough to work at this job, you look like a pair of little BOYS to me!"
The massive, monstrous muscle geezer stomped towards the workers, fire burning in his eyes as he stared down at them, his colossal hairy chest heaving with every breath he took.
"You call those toothpicks muscles? I can barely see you! You look like you're wasting away you tiny little weaklings; take a look at REAL mass." He chuckled and puffed out his immense chest, flexing his arms, bouncing his grandson atop one of his massive biceps.
The poor little guys couldn't fathom the immensity of Grandpa's 600 plus inches monstrous chest inflating to all its glory, when he hit the combination of side chest and the partial biceps display, the little guys were actually screaming and trying to tell him that his entrance was not allowed.
"YOU CAN'T COME IN! This is private property!" One of them shouted, finally gathering strength to face the silver haired behemoth who carried me inside.
"That was a bad move!" I thought as I gulped, because Grandpa's mega dose of testosterone flared his temper so much that he just hit a most muscular pose that produced an aftershock wave, sending the poor little guys against the gate.
Now Grandpa was pissed enough to teach them a lesson for their stupidity. He strode right past the two defeated guards, reaching back with one massive fist and punching through the solid iron gate, hitting it with a single punch so hard that it went flying off its hinges, looking like someone had driven a bus into it!
"A little lesson for your puny weaklings, I go wherever I want. If you think anything can stop me, think again." He chuckled, stomping deeper into the site.
The place was crowded with workers and heavy duty machinery, but Grandpa Burt just strode heroically deeper into the site, watched by the shocked muscle guys. As I stood sat over his monumental shoulders, he caressed the humongous cock, dropping a huge lead of precum behind his super massive body.
All of a sudden, there was this group of 5 "big" guys, the smallest of them standing at least 6'3" and 300 pounds came running down towards us, they were carrying sledgehammers and pickaxes, and the looks on their faces were not friendly at all.
"GET THE HELL OUT OF HERE YOU FREAK!" The leader was a 6'4" 330 pounds blond guy wearing a safety vest and holding the tools in a very threatening way, or at least in a manner I used to think was threatening but when Grandpa Burt just rolled his eyes, I knew they were in for a treat.
The massive old man chuckled and stood before the tiny men, looking down at them.
"Hmph, I will make you little bugs a deal, you hit me as hard as you can, and I'll try to notice it." He laughed, holding me up and planting a hungry on my boyish lips.
"This is my grandson, Bobby...and he's going to make me even bigger, you little wimps will be even weaker compared to me!"
It was really hard for me to follow their actions, because when Grandpa spoke to me, all I could only hear his manly deep voice. When he kissed me, everything seemed to turn into a blur, but this time he actually made strategic pauses, which allowed me to see the guys hitting his glorious physique with all their puny strength.
The sledgehammers shattered against the hardness of his abdominal muscles, the pickaxes smashed as they hit his monumental muscles. Over and over the dangerous tools tried to harm him in vain and by the end they were all destroyed, unable to even scratch my Grandfather's manly muscles as he made out.
The little skinny guys couldn't believe such powerful sight, they just stepped back as Grandpa Burt looked at their destroyed weapons. Then, he gently placed me back on the ground and grabbed the five guys in one side of his mega monstrous bear hug in a second, and just at the very next moment he was caressing my chin with his free hand.
Meanwhile, Grandpa Burt continued to crush the group of men against his massive chest, forcing them to breathe the musk from his armpit, the men coughing and choking on the intense taste of man.
"Hah, are you little bugs finally done? I didn't feel any of that; you guys are even weaker than I thought! Now, it's my turn...and you little boys need to learn who your master is."
"YOU LITTLE FUCKERS ARE TOO WEAK! I GUESS I'LL HAVE TO DO YOUR JOB FOR YOU, LITTLE BOYS!" Grandpa tossed the five muscular men away and just shouted at rest of the crew that he was really disappointed at them, for being so weak and puny.
I watched in awe as my gallant mega geezer grandfather stepped closer to a bunch of 30 feet tall columns these little guys were demolishing. The first one went down with nothing but a single punch fired by the humongous hand that I loved so much.
The power was so intense that it simply pulverized the concrete thing into shreds! I moaned in my pants and Grandpa chuckled, holding his gigantic biceps for my worship, and it was only then I noticed the rest of the guys he had defeated were also very hard.
"HEH, You were taking too long to do something so simple!" Grandpa Burt shrugged .
Grandpa chuckled as he walked towards the next column, and this time he just pushed his massive cock into the concrete surface, easily piercing through the thing, and started fucking the pillar like it wasn't real. But my eyes could see that it was actually made of iron bars and solid concrete, and the impossible fucking continued until he uprooted the column from the soil!
"What do you say, Bobby? Is it fun already for you? Or did you really expect these guys and their silly job would keep me from the thing I really deserve?"
I gulped as my eyes devised the glorious view of my Grandpa attached to a giant concrete column by his mega monstrous cock; it actually made him laugh as he walked towards me with the giant concrete thing impaled to his mega manhood!
The giant muscle grandpa gently hoisted me up, holding my tiny body so easily with one hand, able to crush me like a giant if he wanted to! The look in his eyes was one of anger, it made my body tremble with fear.
"Bobby, why haven't I grown any bigger yet, boy? You had better have lots of plans to make me even larger; I hope you don't think I'll be content with this puny size!"
"Oh...Grandpa, I am so sorry, I mean, I don't have anything to make you huge now...It's just...I can try..." I was so shocked, my cock was aching hard as he lifted me so effortlessly of the ground, I knew he could crush me like a grape, but yet, my massive grandfather was not pleased, he needed to get bigger.
"I'm listening, little boy? You don't want me to get disappointed at you right?" His tone was serious, so I needed to come up with something, anything to make him bigger. It was then that I noticed these other guys were all boned up and jacking to the sight of my glorious Grandfather Burt.
"You know, Grandpa, this might be just a shot in the dark, but your pills are basically pure testosterone composts and these guys are all jacked up on steroids and similar components, maybe if you had their juices you could start another growth cycle..." I still didn't know if I was right, but I REALLY wanted to be right and have my grandfather grow bigger until I get the next batch of his pills.
As soon as he heard that, the massive older man tore the clothes off the construction workers and crouched down, hiking his hairy ass up in the air. Grandpa Burt ordered one to fuck his hole, and grabbed another to start sucking him off while the remaining guys were squeezed against his immense body and forced to rub their cocks against his massive hairy muscles, he'd get their juices one way or another!
I guess I didn't expect my grandpa to be in such need to grow and it made my heart sink inside my skinny chest, but suddenly, as those little guys were moaning and dumping their loads into the glorious body of my Grandpa Burt he was laughing again, his deep voice grunted and I noticed the same kind of bulging movements on his physique before he started growing.
"Grandpa, it is happening!" I just gasped as his glorious physique bulged, the hairy monster sized muscles bucking and growing thicker, hairier, manlier. One by one he was getting the juices of the tiny guys inside his organism and he was hungry for more size and strength!"
"Mmmff, come on you little men, I know you have more to give!" He laughed, sucking harder, forcing the guys against his muscles, even clenching his ass so the one fucking him couldn't escape! He was like a black hole for cum, he needed grow bigger and BIGGER!
At first, I thought his growth wouldn't take off like the previous times, but just then my Grandfather didn't disappoint me, it was like his muscles started growing bigger for the first time all over again, his mind was so determined to milk every ounce of muscle growth cum from those hard workers that soon he was going through the growth spurts and bulging everywhere.
"That's it little fuckers! Give DADDY your muscle juice! Let's make a bigger, manlier Burt!"
I gasped as those guys dumped their loads down my grandpa's butt and mouth and he continued to grow, feeling so excited and marveled with another round of intense muscle growth. I watched as the guys just continued running towards him, suddenly I realized that there were at least 200 men in that place and they were all hard, sweaty, muscular hungry men all horny for my mega massive grandfather, and they covered his glorious muscular monstrosity.
Then, at the bottom of the pile of sweaty huge muscle men, I felt the earth shaking; there was a loud noise and a deep guttural tone that made my heart skip a beat. I realized the little guys were all cumming over each other, feeling overwhelmed by the monster resurging underneath their worshipping figures.
"DAMN, BOBBY, You didn't tell me these little guys were so juicy!" He said as the muscles grew bigger and even more marvelously humongous, the guys were holding to the glorious expanding behemoth of my grandfather, and his transformation took new heights and standards.
The pile of worn out little men grabbed onto the sides of my Grandfather's giant muscle bellies, on each pectoral he should have over 30 little guys, while on his arms he easily supported at least 15 dudes, his monumental legs were thick enough for other 20 guys, while his butt could support at least 25 of them.
It was such a monumental view, there was something so monstrously powerful that my young mind still couldn't fully encompass. At the bottom of such enormous pile, emerged my glorious Grandfather Burt, bigger and hairier than ever, but so outrageously muscular that although he stood at the height of 7'3" tall, his body had to be over 30 freaking feet wide!
"FUCK BOBBY…These guys are all dry already!" The booming voice of my grandfather made me cum intensely over and over, he just towered over me, his glorious cock was over 2 feet and a half long, and so freaking thick that I just shook in fear.
"That's a good thing we have lots of equipment here! Come on you little fuckers, help me weigh this glorious monster body of mine!" The hulking grotesqueness of my beloved super manly grandpa said as he waddled. His biceps were so huge they peaked over ten feet above his head, and his chest stood at least 15 feet from his glorious body. His balls were giant sized cum producers.
I needed to take my time while the construction workers weighed my glorious Grandfather. He just held me in his grotesque arms and grunted.
"Damn boy, I now weigh 35,087 pounds of humongous hairy muscle, and you only made me hungry for more. I hope you don't get any excuses to make your master more muscle pills right?"
I just shook my head as the mountainous man flexed for me, engulfing all my view in muscle, squeezing me in the cleavages of his behemoth standards. I knew right there, Grandpa Burt loved me, and he wanted me to make him grow, this was the only thing that I needed to do in my life now.
To be continued?
