Part 1

It was the evening. Just like any other evening, I was at the gym. Late enough that rush hour was over, but not so late that the night owls were out. I looked around the gym and saw most of the regulars I normally encounter at this time. Even that guy who owned the coffee shop that bore his name with the logo of his face was here. It still amazed me that I could be at this gym, the expensive one. In this city, it was worth the extra money to avoid the crowds. Sometimes I yearned to be in one of those gyms that was a little grittier, just weights in a room. But I was intimidated by those… 

I was in great shape, but on the leaner side. It always felt like, no matter what I did, I could never put on the kind of mass I wanted to. At 5’7” and 140 pounds, I felt much smaller than I was.

I was just about to start my workout when I saw him. The silver daddy, as I nicknamed him in my head. He looked to be early 40s, grey hair, buzzed at the sides, piercing blue eyes. And he was thick. Not the leanest guy around, but his arms had to be the size of both of mine put together. It was always a challenge to focus on my workout, to avoid staring at him. I wanted so badly to engage with him, but I was always too intimidated. 

“What would a guy like that want with me?” I thought to myself. “I’ve gotta be 15 years younger and 50 pounds lighter than him. And, god, at this point my virginity has probably grown back.” I shook the thoughts free and got back to my workout, stealing glances at him whenever I could.

When I finished up, the gym had mostly emptied out; the lull before the night owls come in. I headed to the locker room and stripped down. When I first joined this gym, I was just a few blocks away, but now I had to take the train back to my place. It was worth the commute, but I didn’t like to do it sweaty. Plus, they had the expensive soap here and the nice sauna. With a towel around my waist, I went into a shower stall. 

After cleaning myself off, I stood under the hot water, enjoying the feeling of it running down my skin. I closed my eyes and tried to clear my mind. I was taken out of my zen moment by a rush of cold air. I opened my eyes and turned my head to see the silver daddy, just as naked as I was. I opened my mouth to say something, but he quickly stepped inside and put his finger to my lips. 

I blinked, unsure what to do. I had never been in a situation like this before. Before I could even try to say something again, his finger was replaced by his tongue. His tongue probed into my mouth like he was searching for something. It felt like it filled every crevice of my mouth. I realized my whole body was tense. I relaxed and kissed him back, our tongues battling. 

My dick was rock hard at this point. I always produced a lot of precum and this was no exception to that. My cock dripped like a faucet against his leg. He broke the kiss, looked down at my dripping cock, then looked back up to me and grinned. He grabbed it with one hand and stroked it gently. Again, before I could make a sound, he stuck his tongue back in my mouth.

My hands roamed his wide back. He grabbed my ass and pulled my cheeks apart, exposing my hole to the air and water. His huge pecs rubbed against my modest ones, his strong arms draped over my smaller ones. When he broke the kiss again, he dropped to his knees and took my cock in his mouth.

My head spun. I leaned against the wall for support. I looked down at his large frame and felt his mouth close around my cock. His tongue swirled around my dick as he bobbed up and down on it. I grabbed his hair with one hand and steadied myself against the wall with the other. I was already close. I tried not to cum. As though he sensed it, he pulled off. He looked up at me and grinned. 

Without warning, he spun me around and dove that huge tongue into my hole. I saw stars. I could barely think straight. At first, he struggled to get his tongue very far into me, but he was persistent. Again, I realized how tense I was and relaxed. His tongue pierced further into me. I bit the side of my cheek to stop myself from gasping. I wanted him to jerk me off, but I still didn’t want to cum. I wanted this to go on forever. Just like with my cock, he stopped abruptly. He spun me back around and kissed me again. I felt his cock throbbing against mine. I was big, close to 8”, but his was thicker. Everything about him was thicker, even his ass. And I was known for having a big ass.

This time, I broke the kiss. I wanted to taste him. I started to kneel, but he stopped me. He shook his head. He grabbed the back of my head and guided it to his chest. I immediately latched on to his nipple and sucked. I flicked it with my tongue and I felt him shiver. I bit down lightly and he inhaled sharply. He pulled me off and guided my head to his other nipple. I gave it the same treatment before he pulled me off that one, too. He looked me in the eye, those bright blue eyes, and smiled. His teeth were a brilliant shade of white. Then, he did something I never expected.

He turned around and guided himself on to my cock. Now my head really started to spin. His hole felt so good, like it was made to be fucked. He rode me as we stood in the stall. He guided my hands from his hips to his chest. I squeezed his pecs and tugged at his nipples. I felt his arms; I could barely dent them with my hands. I moved one hand back to his chest and pulled on his nipple again. With my other hand, I started jerking him off. He rode me faster. 

I simultaneously felt like I was his toy and like I was an active participant. It was incredible. I loved the feeling of being used for his pleasure and I loved how good he felt to use for my own. I leaned my head back against the wall. As I pinched his nipple again, I felt his cock plump up in my hand and start spilling his seed in the stall. His hole clamped down on mine as he shot over and over. It seemed like an abnormal amount of cum. I couldn’t stand it any longer. I tried to tell him I was going to cum but he leaned back and pulled my head in to kiss him again. As our tongues met, I unloaded in his ass. It felt like the biggest load I’d ever cum, but nowhere near as large as his. 

When I finally stopped cumming, he pulled himself off me. He turned around and kissed me again. He once again put his finger to my lips. He winked, then opened the door to the stall, looked around quickly, and slipped out. 

I stood in the shower for a long moment. I would have thought I passed out and the whole encounter was just a dream if not for the cum all over the floor of the stall. I couldn’t believe his cum hadn’t all been washed down the drain yet. I did my best to clean it up before I gave myself a quick rinse again. 

When I finished up, I looked around for him in the locker room. My heart sank as I didn’t see him anywhere.

“Of course,” I thought. “I should have known it was just a hookup.” I dried myself off and got dressed, trying to appreciate the moment for what it was and not getting hung up on what I had hoped it could be. 

I walked down the stairs and waved to the person at the front desk as I exited. They smiled and waved back. I reached for the door, but it opened for me. I looked up, prepared to step out of the way of someone entering. No one did. Instead, I saw him, holding the door open for me.

“Took you long enough,” the silver daddy said. “Which way are you heading?”


Part 2

Since we met last week, I’d seen my gym crush a few more times. We hadn’t repeated our shower tryst, but we had hooked up twice more. Oddly, while he always wanted me to cum, he always stopped before he did. While I wasn’t about to turn down any chance to hook up with a guy this hot, it was disappointing, given how much I love cum. Oh, and I learned his name: Mike. Somehow, it both fit him perfectly and felt too average for him. 

I found myself fidgeting anxiously while I waited for him to show up. I’d cleaned the apartment earlier in the day, but I kept finding things to clean up, just to have some way to get the energy out. It didn’t really work, but it passed the time well enough.

“Hey,” he said, as I opened the door. If it felt like a bolt of electricity when I looked him in the eyes, then it felt like a heart attack when he kissed me. We didn’t just hook up, but it was up there for me in terms of my favorite things to do with him so far. 

I could not get over the feeling of his tongue filling my mouth. I tried to press my tongue into his mouth, but he kept his firmly in my mouth. Sometimes, he’d relinquish some control, but not today. Today, I could tell, he was getting what he wanted, and I was going to let him have whatever he wanted.

He closed the door behind him without breaking the kiss. He kicked off his shoes as we walked back toward the couch, still kissing. He tasted great. Not like he just brushed his teeth or any kind of strong taste, but fresh. And he smelled so good. 

Finally breaking the kiss, he pushed me down onto the couch. He pulled his shirt off, the bottom sticking to his wide lats. I watched as his pecs popped free, practically drooling. I watched his traps flex as he discarded the shirt. He grinned and flexed one arm. 

“Like what you see?” he asked.

“Oh yeah,” I said. I tried to stand, but he pushed me back down.

“Tell me what you want,” he said.

“I want to taste you.” He stayed quiet, watching me. “Please.” I said, practically begging. 

He smiled and lowered himself onto my lap. He pulled my head to his chest and I immediately went for his nipple. I attacked it with my tongue before I started to nibble on it. 

“Harder,” he said. I obeyed. 

My hands roamed his back, but he pinned them down. I felt like my dick was going to rip right out of my jeans. He moved my head to his other nipple and I gave it the same treatment.

“Tonight, I’m going to share everything with you,” he said. “If you think you can handle it.” He pulled my head off his chest. “Do you think you can?”

“Yes,” I nodded. “I can handle it.”

He smiled. Before I knew it, he had taken my pants off, pulling my jock off with it. I quickly tossed my shirt to the side, as well. 

“Good,” he said. 

My cock was already dripping. Precum ran down my shaft. He looked down, approvingly. He got off my lap and kneeled in front of me. He took me in his mouth as he wiggled out of his pants. I looked down at his huge ass, his cheeks spreading as he sucked me off. He swirled his tongue around my shaft. I grabbed the back of his head and started to pump my hips, but he pushed my hands away, wordlessly reminding me he was in charge today. I complied, waiting for his instruction before I acted. It was driving me crazy not being able to fuck his face, but I was getting off how much he seemed to enjoy being in control.

He continued sucking me for several minutes. He alternated bobbing up and down my shaft, to swirling his tongue around the head of my cock. He pulled my dick out of his mouth and licked the underside as he jerked me off. He shifted himself, so my knees rested on his broad shoulders. He maneuvered me, exposing my hole. He slipped two fingers in, slick with his saliva and my precum. I moaned and wiggled on his fingers, wanting them deeper. He took my cock back in his mouth as he fingered me.

“I’m so close,” I said. 

Instead of stopping, he sped up. He put a third finger inside me and pumped his fingers in and out, in time with his head bobbing on my cock. After a few seconds of that, I exploded in his mouth. He sunk his head down to the base of my dick, my cum shooting directly into his throat. He swallowed every drop. Pulling off, he smiled.

He stood up, then sat back in my lap. He was so heavy, it felt amazing. He kissed me hard again. I could taste myself mixed in with the taste of him. He broke the kiss.

“That was amazing,” I said.

“We aren’t done,” he said. He raised himself off me and stood back up. I admired his body. His quads sweep, his beer belly, his huge arms, his thick cock. “I told you, tonight you’re getting everything.”


Part 3

He towered over me, a cocky grin on his face. His hard dick was dripping more precum than I’d ever seen before. It looked enormous. I could swear it was thicker than just a few minutes ago.

“Are you ready?” he asked. I nodded. “Good.” 

He grabbed my legs, forcefully, but not roughly. He pushed my knees back into my chest and leaned over me. I felt the head of his cock rubbing against my hole, drenching it in precum. He pushed his hips forward and it started to enter me. I felt his precum making my hole slick. He leaned down, pushing his weight into my knees. It was slightly harder to breathe, but I loved how heavy he felt on top of me.

He leaned forward. His control was incredible: Instead of shoving more cock in me, I felt just a few more centimeters slip in. God, I wanted him to give me more. He leaned his face close to mine. I thought he was going to kiss me, but he spoke instead.

“I know what you want,” he said. His voice was quiet and confident. “I know what you like: You want someone massive. Even bigger than me. I can tell. I’m good at finding guys like me.” He pushed his hips forward again and kissed me hard. I moaned into his mouth as the first couple of inches of his cock stretched me.

He broke the kiss and spoke again. “There are guys at the gym bigger than me. I want to be bigger than them. But I have something they don’t.” 

My head was spinning. We’d never talked about this, but he was right. I did want him to get even bigger than he was. He was only a couple of inches taller than me, but he said he was 225 pounds. He was already huge. But he wanted to get bigger.

“Do you want to know what I have?” he asked. I nodded. “I can do this.” He smiled and started to push the rest of his cock inside me as he kissed me again. His tongue filled my mouth, his cock filled my ass. He had fucked me before, but this felt different. He definitely felt bigger.

As he kissed me, I felt it: He was getting heavier. My eyes shot open and I looked down. He wouldn’t let me free from the kiss, but I could see his shoulders widening, his traps filling out. His pecs, pressing against my knees, grew larger, forcing my knees even closer to my body. I would have gasped if his tongue wasn’t trying desperately to get to the back of my throat. All the while, he was slowly pushing more and more of his cock inside me, made easier by the copious amount of precum his dick was pumping out. I could feel it stretching me out, inch by inch. I moaned loudly into his mouth.

I threw my arms around him and I could feel his back widening under my grip. I moved my hands to his arms. His biceps ballooned out, almost like he was flexing them, but they just kept growing and growing. My eyes widened.

Finally, when he was fully in me, he broke the kiss. I gasped for air, panting. “How’s that?” He smiled. He flexed his newly grown biceps and my dick started leaking precum anew. I was so hard it hurt, even though I had just cum. He slowly moved his hips, starting to fuck me.

“How?” I stammered. I looked up at his huge, smooth muscles. His chest looked like it was ready to burst out of his skin.

“I’m just special,” he said. “Had enough?” 

“I don’t know,” I said. “Is there more?”

“Oh, there’s more,” he said. “But first, I need to get you ready for it.” 

Before I could say anything, he really started to fuck me. I felt the full weight of him slamming into me. He must have put on another 50 pounds. His once massive frame was now gigantic. His cock was absolutely pummeling me. It hurt, but not so much that it was unpleasant. I had never felt so full in my life. I felt as wide as having two cocks stretching me at once.

My senses were overloading. The feeling of his cock inside me was incredible. If this were any other man, I would have been fully entranced by that feeling. But with him, this smooth, monstrously muscular man, I couldn’t give all my focus to my ass. His body stole the focus away, and deserved my attention and admiration. His chest bounced as he railed me. He grabbed my feet with his hands and pulled them apart, his biceps stretching out as he did. His belly shook when his hips collided with mine.

“Fuck,” I said. “This is amazing,” I somehow managed to say. “Please don’t stop.”

“Oh, I’m not going to stop,” he smirked. “Not until you take every drop of cum in your hole. I love being your muscle cum pig, but today, you’re mine.”

“Please,” I said. “I need it.”

“You want to be my cum slut?”

“Yes,” I said. “Fill me with it.”

“Careful what you wish for,” he said. 

He slowed his pace. He shifted his hips from side to side, his dick moving around in my hole. He pumped back and forth slowly.

“You’re feeling pretty loose now,” he said. “I’ve really stretched your hole out.”

“I don’t care,” I said. “As long as your cock fits.”

He grinned. “Well, it does right now. But let’s see what we can do about that.”

Immediately, I felt his cock inflating. My eyes went wide. My hole stretched around him yet again. The pressure was intense. It hurt, but I didn’t want it to stop. It was growing somewhat in length, but the girth was where the real change was happening.

“Holy shit,” I said. “Oh my god.”

He smiled again and sped up his thrusts. I gasped. Between the pressure in my ass and his massive weight slamming into me over and over, I could barely breathe. The breaths I could get were short and shallow. I was seeing stars. 

“Don’t stop,” I managed to say. 

Another lurch as his cock got even thicker and even longer. I don’t know how there was space inside me for it, but if there wasn’t, he was making space. If he had stretched my hole before, it must be ruined now. But I didn’t care. All I wanted was for him to keep fucking me with that enormous tool. If he reshaped my body to fit him, I didn’t care. As long as it fit.

He continued fucking me slowly after the growing stopped, letting my body adjust. Slowly, he pulled every inch out. I moaned, longing for him to push it back in. And he did. I don’t know how many inches it was now, but it felt unending as he slowly pumped his cock back into me. Another inch, another gasp. When he was fully in me, he leaned down and kissed me again. 

Somehow, it surprised me when I felt his tongue growing, too. He shoved it to the back of my mouth and I gagged slightly. It was huge. I felt like I was getting fucked at both ends and I was loving it. I moaned into the kiss and he started fucking me faster again. I was grateful for all that precum he was pumping into me. His dick was effortlessly gliding in and out of me now.

“Good,” he said as he pulled his tongue out of my mouth. “You’re ready now.” 

He put my ankles on his shoulders as he stretched himself back up. He slammed into me over and over. My head shook from the force. His pace increased and his breathing was speeding up, as well. 

“You want my cum?” he asked. 

“Yes,” I said.

“You like all this muscle fucking you?”

“I do,” I said. “I love it.”

“Maybe I should get even bigger,” he said. “Maybe I should hold you down and ride you. Put that cock in my ass and flex while I’m on top.” He slammed his cock in hard. “You want that?” I nodded. “Shoot that load up into me, make me grow while I’m riding you. My huge cock dripping on you while I milk the cum out of you. Shoot all over your face and chest.” 

That was it for me. My cock fired cum out shot after shot, as he talked. My ass tried desperately to contract on his dick as I came, but it was impossible.

“That’s right,” he said. “Cum for me,” he groaned. “I feel your hole trying to tighten up, but I’m not going to let it. I’m keeping it nice and loose for me.” He started fucking me even faster. “Here it comes.” 

He leaned down and shoved his tongue back in my mouth as his cock started throbbing inside me. We moaned together as he fired again and again inside me. I could feel it pooling inside me. Over and over, he came inside me. I thought back to the shower, when his cum was still there after he left. I thought about how he would never cum when we hooked up before. Now I understood. There was so much of it. It wasn’t stopping. I didn’t want it to. I wanted to know how much he could shoot. I wanted it all inside me.

If I felt full with his cock, I felt absolutely stuffed once his cum joined his cock. He kept fucking me, slower now, and despite how I had just cum, he was still fucking me wide open. He stopped kissing me and sat up, pushing his cock deep inside me as he continued to cum. I burped and I could taste his cum. I looked down and my once-flat stomach now jiggled as he slowly withdrew his cock and shoved it back in again. My head spun. 

“Fuck,” he groaned, pulling his cock out slowly. Cum poured out of my hole. I tried desperately to clamp shut, to keep his cum in me.

I looked up at him. His dick was enormous, even as it was softening. It perfectly fit his newly grown frame. I had no idea how it had fit inside me, but I was really glad it did. I was exhausted, but I already wanted it back inside me.

I felt bloated, like I had just chugged a bunch of milk or something. I could still taste his cum in my mouth and the reality of that was slowly hitting me. I looked down at the beer belly he had given me.

“Guess I need to do a little cardio,” I said.

He laughed. “Nah, give it a second.”

Just as I was about to ask him what he meant, I felt it: My whole body tingled. It felt like I was cumming out of every cell in my body. I felt myself growing, as he did. Not as much, not anywhere near as massive, but growing. My arms put on two inches, my chest popped out. I felt my ass grow against the couch. My dick hardened again but kept growing beyond its normal size. 

When the growth had subsided, my dick was about an inch longer and thicker and I looked like I had put on 10 pounds of muscle. I panted heavily, my dick still painfully hard.

“All right,” he said. “As much as I love being this size, half the fun is the growing part.” He started to shrink back down to his normal size. “But, maybe I’ll keep a little extra on this time since I like ya.” He winked at me. “Don’t worry: You can keep your size this time.” He looked down at my hard cock. “Let’s see if we can’t go for a third load from you.”
