Titan Formula

“All you have to do is drink this and it’ll change everything.”

Aaron stared at me completely confused. He had no idea how I had gotten so big and I loved watching his eyes try to take in every bit of me. I’d recently been gifted some kind of app that was able to change everything around me, but there was no way I was going to tell him that. I’d started off a bit small, just a few inches taller and a couple of pounds of extra muscle. But each day I couldn’t help but add a bit more. Feeling the strength in my rapidly growing muscles was just too much to not give into. 

Now I was standing just under 7 feet with nearly 400 pounds of thick corded muscle. “There’s just no way…” Aaron stared up at me wondering just how I’d grown so much. I shrugged my heavy shoulders. “There’s just no way…”

“But then how do you explain it?” 

He didn’t have an answer. But then again there was no way he could ever think something on my phone could do this either. “Just try it,” I pushed the protein powder closer to him. “What’s the worst that could happen?”

The skeptical look on his face was enough to say that he didn’t really trust it. I wasn’t known for too many practical jokes either. “You sure?” his hands were moving closer to the shaker bottle. “It’s just I’ve never--”

“Just try it,” I groaned.

“Fine. Fine.” He was getting defensive but still grabbed the bottle. Aaron was still overthinking it as he brought the bottle to his mouth. He shook the liquid around as though it was supposed to do something unexpected. Then tilted it back slightly. I rolled my eyes and tipped it further back for him. He coughed but when he realized I wasn’t going to stop, he quickly learned to swallow.

“That’s it,” I went to my phone pretending I’d gotten a message. With my massive fingers it was a bit harder to use, but I could still type fairly quickly. ‘Each time Aaron drinks a bottle of Titan formula his body grows like he’s been working out to grow as much as possible for a year.’ I hit enter like I had been for the last week and a half but this time a new box popped up. ‘Would you like the target to be aware? Yes/No’ I looked over at Aaron flexing in the mirror, ready for the growth to happen. Something inside me felt a bit devious and I clicked, ‘no.’

I watched as his belly and the fat around his arms started to tighten up just a little bit. His jaw grew a bit squarer while his neck leaned out. More subtle details to his posture, like him standing up straight and posing to show off his muscles, surprised me the most. “You sure this works?” he turned back and looked at me.

“Maybe you haven’t had enough?” I shrugged. 

His eyes narrowed as he mixed himself a little bit more of the ‘Titan Formula’ into the shaker bottle. He looked a bit more confident as he did so. I realized that just because he had changed a little bit, I wanted to see more. I went back to the device and added another bit. ‘Whenever Aaron drinks the Titan formula it’s the maximum amount of growth he could grow.’

“Fine,” he took another drink of the drink and went back to the mirror. To him nothing looked any different. But to me, I could see his belly disappear completely. The subtle outline of six bumps replaced it. His arms were fuller, forearms looked defined and hands thicker. Even down in his jeans, a thick ass pushed out behind him while his quads and calves pushed against the rest. But I didn’t expect his plain looking shoes to turn a brighter color. They looked more athletic than they had been before.

“How do you feel?”

“Same,” he said. He tried flexing a bit more, watching the bump that, a few minutes ago, was non existent. But now there was some clear definition. Each muscle had a bit of a shadow showing off more and more of his definition. “You sure this works?”

“Yeah. I’m sure,” I smirked. “I’ve been using it for a few weeks now, this is your first time.”

“So I still haven’t had enough?”

Did he suddenly have a greed for growth? I felt a little giddy as he was already filling up another helping of the Titan formula, but this time he doubled the dose. “I don’t know if--”

“Bite me,” he didn’t let me finish.

I felt my dick throb at the proposition. It took a second to calm back down but I turned back to the device. ‘When doubling the Titan Formula it quadruples the effects.’

Aaron downed the drink and went back towards the mirror. Even as he was walking I could see his body pulsing with more and more power. His shoulders broadened enough to tear away at his sleeves. The veins in his bicep pushed out of his skin and even without flexing there was a dip showing off his triceps. The same thickness ran through his forearms down to his hands.

“So when does it start working?” he was too busy posing in front of the mirror to look at me. So distracted with wanting to see the growth, he’d dropped his pants, showing off the underwear that was wrapped tightly against his thighs. “Cause I don’t see shit.”

“I don’t know,” I shrugged. He sounded so much more confident in how he was speaking. I smirked a little, seeing how much he’d grown in such a short period of time.

He must have taken it the wrong way as he filled himself up another double of the Titan Formula. He quickly downed it and started growing again. His muscles pulsed even more. There was a waddle in his walk as the thick quads rubbed up against each other with each step. He threw up his arm for a flex. The already thick arms surged past 20 inches. While his heavy chest pushed hard at the sleeveless shirt he was wearing. 

“Still nuthin,” Aaron growled at the inability to see his growth. “You sure that shit werks?”

“Yeah, I’m sure,” I said. Though it was the first time I realized that he was talking so differently. “You feel okay?”

“Yeah man, Just fuckin hate how I can’t seem ta grow no more. Got ta a point where I’m big yeah, but like fuck. Just wanna be fuckin bigger. Like look atcha. How’d a fuckin shrimp like you get ta be like that?” 

He didn’t sound like the accountant I had first moved in with. But with how much he’d been drinking that meant that he started working out when he was about 16. His entire personality seemed to be different as he tried to posture himself up more. Or maybe it’s just he never thought I could be as big as him, let alone standing a good head taller with muscles just as thick and wide. 

“So how much of this shit did you drink?” he looked like he was going to go back to it. 

“Well, I have been drinking it for a couple of weeks now,” I reminded him. “Maybe it just takes some time before it starts to work.”

Aaron let out an angry grunt. “Well it ain’t fast enough.”

I felt my dick throb at the comment. Never would I have thought that his passive personality could be taken over with such a greed to grow. Maybe it’s just he never felt confident enough to try or more because he thought he should just be big, but I couldn't get over just how much he’d changed. ‘A side effect of drinking several scoops of Titan formula within 20 hours causes the consumer to want to bottom for other men until the formula has made it out of their system.’ 

The moment I hit enter, I could see Aaron start to squirm a little bit. His thick ass shook back and forth as he was thinking about making himself another portion of it. Aaron scrunched his face up as a thought that he’d probably never had in his life, entered his mind. That thought seemed to worm it’s way deeper into his subconscious as he stuck his ass even further out. The round globes pushed his underwear to the max, showing off their definition.

“You alright?” I prodded.

He let out a light grunt. “Ye-ah,” he forced out to try to disguise it. “Just can’t decide if I wanta make anuther one.”

“Probably don’t need it. I think you might be big enough.” Aaron’s hips thrust at the complement. He forced down another grunt as his dick pressed against the counter in front of the sink. “You alright?” I asked again.

“Ye-yeah,” he was having difficulty concentrating. His eyes seemed to be trying to lock onto me. The more he looked the more he tried to force his eyes away. “Yo, you know if there’s any kind of like side effects for this shit?”

“Besides watching you’re sexy ass waddle around our kitchen?”

“Oh fuck yeah…” he moaned. His neck pulled back against his back as his weight dipped more into the sink. Aaron caught himself but just barely. The loud sensual moan was still in the air but he was going to pretend that it hadn’t happened. “Y-yeah. I think I’m starting to feel funny...”

“Oh, okay,” I stood up from the kitchen chair and walked over to where he was standing. I purposefully stood behind him and reached my arms around to grab the box. “I’m not sure, I’ve only ever taken it as the instructions said. I’m pretty sure you weren’t supposed to have more than a scoop or two in 24 hours.

Aaron’s body was fighting to hold itself up. He gripped the sink tightly and his whole face seemed to have scrunched up. “Re-really?” he pushed his weight against the sink trying not to touch me at all.

“Really,” I invaded the small space he’d made. He gripped the sink even tighter. His thick hands did their best to hold onto the smooth metal surface. “Oh jeez,” I pretended to sound surprised when I found the warning label. It wasn’t very convincing. “Looks like you want to have sex with other men if you have too much in a short period of time. Is that true?”

A weird series of grunts, groans and moans, exited his mouth as he tried to deny what he was feeling. But with my large body covering his over the sink, it was near impossible for him to think about anything else. I was sure he could smell my distinct smell. Feel my skin against his. And think about nothing other than me right above him. 

“I don’t know if it would be,” I continued to act surprised. My hand gently ran up his bicep and crossed over onto his thick chest. A finger gently rubbed against his nipple. I leaned in closer, whispering. “There’s no way you could feel that way right?” 

His body went limp again. The thick strong muscles gave way to his desires, making him just as weak as he had been before. It didn’t matter how much muscle was there, he couldn’t hold his body up anymore as his face fell in the sink. “Just fuck me,” his voice was low and said between breathes.

“What was that?” I pretended not to hear.

“Just fuck me,” it was a little louder.

“Just duck me?” I teased.

“Just fuck me!” he shouted loudly as he thrust his thick hips against mine.

“Oh… Why didn’t you just say so,” I pulled his underwear down and set my dick free. Another thing that I had grown just a little bit. But made sure that it wouldn’t cause any damage. It didn’t matter how tight the hole, I could still push in nice and easy and it still feel like they were being pounded by the extra tall beer can it was. That little device seemed to be capable of anything.

Just pressing against Aaron’s asshole, he lost his grip again and fell into the sink. I gave him a second to hold on as I thrust again. He gasped loudly feeling his body filled up with my thick dick. He could feel the pressure deep inside of him, thrusting back and forth. Each one drew another heavy moan from his lungs. 

More of my weight pressed him down against the sink. I felt myself so close. Hearing the depth of his voice, scraping to gain air as the pleasure overtook him was more than I ever imagined. Then feeling his hips thrust involuntarily as he sprayed the front of our sink sent me over. I finished right alongside him, dumping large amounts of cum deep inside him. 

The heavy breathing was enough to know that we were both spent. I pulled out and went back to where I was sitting. “Pretty good stuff, eh?” He nodded looking over the box again, almost like he wanted more.
