Beyond the Math

“+SizeKing Extract. One drop adds 10% to 20% of the initial size. Bottle contains 10 drops. Blah, blah blah.” I read the label on the small bottle once again, with a devilish and lustful smile on my face. “Be careful with dosage. Effects might be different depending on the person. Blah, blah, blah. Genetic predisposition, blah, blah, blah. Well, I love the results so I’m sure he’ll love what this will do to him too.” I looked at my reflection in the mirror while I rubbed my huge 12 inch long dick, that had been 7.5 inches long just a few hours before. I had only taken 5 drops and I was saving the rest of them for a very special person, my best friend

I knew my best friend was about to arrive because I had invited him to my apartment for a special dinner, so I tried my best to fit my big dick in my pants once again but it was really difficult. Considering I had never been that hard in my life and I had never been that big either, everything was incredibly new to me so I had trouble with clothing. I really wanted to keep rubbing my big dick and playing with my big balls because they were very sensitive but I was more interested in seeing the effects the product would have on my best friend. He didn’t know it yet but I had a major crush on him and I wanted to give him a nice surprise.

While I fought to get my dick in my pants, I thought about the new shop a few blocks away from my apartment where I had gotten the +SizeKing Extract. The big blonde guy who ran the shop told me his husband had created it and even though it sounded crazy, I decided to try it. They had several other options, most of them advertising bigger gains but I didn’t want to go that far so I picked the most simple one. I never thought it was actually going to work but my issues fitting my 12 inches long dick in my pants was proof that it really worked.

Once my dick softened a bit, I was finally able to fit it in my pants. I wanted to look as nice as possible but I wanted my big bulge to be pretty obvious, without scaring my best friend. He was by far the hottest man I had ever seen so I wanted to impress him that night. He was 23 years old, just like me, and pretty tall at about 6’3”, while I was 6’0”. He weighed around 220 pounds of muscle, 40 pounds heavier than me, and I knew a big dick would be the perfect complement for a big guy like him. He was already perfect but bigger is always better.

When he arrived, dinner was ready and I could barely contain my excitement. He looked especially hot that night because the button down shirt he was wearing was tight on him, all in the right places. We went straight to sit by the dining table and I started bringing our food while he told me about his day. I knew he was always hungry so I had big portions ready for him. He was a big guy so his body needed lots of food to work and I was more than willing to give him as much food as possible.

He said he was pretty thirsty and asked me for a glass of water before we started eating. I didn’t hesitate and added the 5 drops of +SizeKing Extract that I had saved for him to the glass of water. He drank it in a blink and I could only smile. I couldn’t wait to see the results and my excitement was making my dick hard.

“Buddy, may I know what the occasion is? You mentioned you wanted to show me something and give me something?” He asked while he kept eating but I noticed his left hand traveled down to his own crotch constantly. That meant the product was already kicking in.

“Yeah. I got something really cool and I wanted to share it with you. But be patient and soon you’ll find out." I replied but I knew he was a very curious person.

“Come on. Show me what it is. You know patience is not my thing." He said and smiled kindly at me. That smile always made me go weak.

“Hmmm. Okay. Let me show you but promise me you won’t freak out. Okay?” I stood up and started unbuttoning my pants. He was clearly in shock but he didn’t stop me. “Yesterday, I went to this new shop and the big big blonde guy who runs the shop told me about this product, +SizeKing Extract, that could make me grow. It sounded pretty cool and pretty easy to use. A small bottle had 10 drops and each drop added 10% of the initial size of the dick and balls. So I took 5 drops and my dick went from 7.5 when fully hard to a whole foot long.” I said as I lowered my pants and underwear to reveal my 10 inches long semi-hard dick

“Dude, are you fucking kidding me? You want me to believe that your dick grew? You don’t need to create the whole story to show me you’re this big. Though I don’t mind the show.” He sounded really cool about it and that was not the reaction I was expecting.

“Bro, I’m fucking serious. My dick was 7.5 before and now it gets to 12 inches when it’s hard. Aren’t you impressed?” I asked and he smiled at me.

“Yeah. Pretty cool” He pretended to be excited but I knew he didn’t believe me.

“You’ve always been a bad liar so I don’t eat your fake excitement. You don’t believe me but soon you will. I’m sure you’re already feeling the effects of the product in your body.” I said and he looked at me, pretty scared.

“What do you mean? You didn’t give me that weird thing of yours. Right?” He sounded really worried and turned a bit pale.

“Yes I did. I saved 5 drops for you and added them to the glass of water you drank a few minutes ago. Soon you’ll have a big dick too. Remember I asked you yesterday how big your dick is? And you said it’s 8.5 inches? Well, I was doing the math and you’ll have a 13.5 inches long dick in a few minutes so… you’re welcome.” I said with a big smile on my face but he looked terrified.

“You gotta be kidding. You can’t be serious. I hope that shit doesn’t work or you’ll be in lots of trouble.” He stood up and started taking his pants off too.

“You sound like a 13.5 inches long dick is a bad thing. Who wouldn’t like a dick that big.” I asked in confusion.

“A person who already has a 13.5 inches long dick. I lied. I mean, kind of, my dick is 8.5 inches long but when soft. I’ve always been ashamed of being that big because it makes me feel like a freak but it’s 13.5 inches when it's hard." He said and I turned pale because he lowered his pants and I could see his soft dick on full display and it was easily 9 inches long. “You see? It's not hard. At all. And… fuck, I can’t believe you did this to me. Fucking asshole.” He said when he noticed his dick was growing.

I apologized over and over again but I couldn’t help but get hard in a blink. He ignored me and just looked at his dick and balls while they kept getting bigger. While we were in silence I did a quick math and I thought the +10% per drop would grow his dick to about 21 inches long, which was still a lot but didn’t sound like something extreme. Even then, when he heard that number, he looked harsh at me and lifted his soft dick up with his hand, probably in disbelief of how big it was getting. Then he fondled his balls with the other hand and they were already filling up his big hand to the brim. They looked incredibly full and it was clear they were very sensitive.

It felt like an eternity while his dick kept growing but then it stopped at about 13 inches long but it was still fully soft. I thought my math was correct and I smiled at him.

“You see? It stopped. That’s not that bad.” I said and he looked harsh at me again but I noticed he wasn’t as mad as before. “Told you, 21 inches when hard and...”

“Shut the fuck up! I’m still feeling odd. This isn’t fucking over.” He said and then his dick started getting longer much faster and I realized it was getting hard.

His breathing started getting shorter and he looked even more distraught than before. It was like the world around him disappeared. He started rubbing his right pec like he was uncomfortable or something and I could hear him groaning softly. I noticed his shirt was looking tighter on him and his dick soon reached the 21 inches mark that I had predicted but it didn’t stop there. I wasn’t sure what was happening to him but he started groaning louder and I got closer to him. I placed my hand on his left pec while he rubbed his right one and I noticed it was extremely hot.

“What did you do?” He said and I felt his pec pulsating and getting slightly meatier. The rest of his upper body was getting bigger too.

“This was supposed to only grow your dick and balls. 10% to 20%. Oh, wait, this is the 20% and not the 10%. But still, it should be only your dick and balls that grow but...” I looked down at his dick and it was easily 2 feet long already and thicker than my forearm. Even then, the growth wasn’t stopping.

“You sure?” He asked and his right sleeve ripped loudly, soon followed by the left one. He was panting all along and I was getting worried.

“Well. No. I just assumed he meant dick and balls but he…” I was interrupted by his buttons giving up so his torso was on full display as his pecs continued growing. I wanted to bury my face between them but I knew it was not the moment.

While we were both in silence, I did another estimation but I didn’t tell him because he was already mad at me. He just needed to know his dick was still growing. Thick veins were covering his shaft and the head was so pumped up that it shined under the light of the room. I literally could hear his balls producing more cum than ever before as they got bigger. Saying he had a horse dick and bull balls was not enough, at all. He was far beyond that and his growth wasn’t stopping yet.

His thighs were getting so thick that he had to move his feet farther from each other. He still had his pants around his feet so I helped him take everything off so he could grow freely. I was scared but at the same time I was extremely turned on. My biggest crush was turning into a muscle king right in front of me and I had free access to his incredibly hot body. He looked great from the very beginning but he was growing beyond my wildest dreams and I wanted more.

I helped him take off the remaining shreds that used to be his shirt and once he was fully naked, I could only gaw at the huge adonis I had in front of me. I was a bit hesitant at first but I got closer and my hands started rubbing his upper body, making him moan in pleasure. I started rubbing his broad shoulders that looked as wide if not wider than regular doors. His huge traps were getting so thick that his neck was surrounded by muscle, making it a little bit difficult for him to turn his head to the sides.

His arms were getting so thick that his biceps fought for space with his huge pecs and wide lats. His arms were for sure thicker than a regular guy’s legs and they were still growing. His biceps were bigger than footballs and when I caressed them, they were harder than stones. He had thick veins covering his huge arms and that made them look even bigger. I wanted to have those arms around be so bad but I had so many other body parts to explore first.

My hands went to his huge pecs, that were probably the ones growing the most because they were sticking out over a foot from his torso while also reaching pretty high to his chin. I knew he had a hard time seeing anything past them but they were still getting ticker and I loved them. I massaged his pecs and lifted them up, testing how heavy they were and I was amazed by how full they were. I couldn’t get enough of them and they were still expanding in my hands. With each heartbeat, his pecs grew a little bit further in front of him. With each heartbeat, the cleft between his pecs was getting deeper. And all along, my dick was hard and my mouth was literally drooling.

His nipples were hard and pointing down, they were pretty big but they looked tiny between so much muscle mass. To me, his nipples looked delicious so I had to stop myself from licking and teasing them. He definitely loved his new huge pecs because he moaned really hard while I kept massaging them. I couldn’t take my hands away from his pecs but my eyes were on his massive-wing-looking lats getting incredibly big too and pushing his arms higher.

While my hands were still on his pecs, I looked down at his abdomen and it looked like it was made of stone too and even though it had thickened a bit, it was just pure muscle mass. He really needed a strong core to support his huge upper body. His abs were literally fighting for space, like several softbalts squeezed together. I could see the lower rows of abs getting more and more defined every second. Actually, the overall definition was simply insane and considering his size, it was surreal.

His lower body was just as impressive and couldn’t get enough of it. His thighs were massive and I took a quick look at his back side to check on his massive ass. You could still see how his asscheeks were getting bigger and more muscle mass was being added to his butt. I wanted to bury my face between his asscheeks but I got back to his front and focused on his huge dick that seemed to be finally reaching its max size.

By the time the growth stopped, he was panting heavily. His body was huge. I had never seen a person as big as him. When I touched him, fuck, it was so incredibly hot that I could barely control myself. He was bigger than any bodybuilder and the best part, and what made the biggest difference, was the size of his dick. I tried to encircle his huge dick with my hands and I was incredibly far from doing it. His dick was close to three feet long and about 9 inches in diameter, and his balls looked as big as soccer balls. I reached down and lifted his balls up a bit, just to let them fall again and I loved how full they looked. This made him finally come down from his high and he looked down at me with a devilish look.

“I hope you’re happy. I’m a freak now.” He tried to sound mad but he was clearly loving his new huge body. “What am I gonna do now? I weigh like 500 pounds and I don’t have any clothes to wear. I can’t move that easily anymore. My dick is huge and I can barely see anything behind my pecs.” He said and his dick started leaking pre like a faucet, proving he was turned on instead of mad.

“First, stop pretending you’re mad. I know you love this. Second, you’re a total muscle king and I’m willing to serve you from now on. You’re so big, bigger than 500 pounds for sure. You’re so perfect. And third, this dick, fuck, so incredibly hot. Beyond my wildest dreams” I said as I got my mouth around his dick slit, making him moan louder than ever.

“And beyond your math too because this is not what you said that crazy product would do to me.” He said between moans and I continued sucking on his dick. “Now I’ll need all the available hands to take care of me so I hope you’re serious about serving me.” He bounced his pecs and

“Don’t worry. I’ll be completely yours from now on. I turned you into a huge muscle king and now I’ll serve you like you deserve it. You’ve always been the hottest man around but now you’re beyond that. I’ll do anything for you, just say it and I’ll do it.” I said and he smiled big while his dick leaked pre like a river

“Only one thing, I need to know where that shop is and if they have more of that product you gave me?” He reached for his dick and rubbed it while I kept licking and sucking its huge head. I only smiled and thought about all the other products the blonde guy had in his shop. I looked up at my best friend’s face and I knew he still wanted more and I was willing to give him whatever asked me for.

The End
