Asher spent his entire first semester working out and gaining some serious muscle, but when he returns home for winter break, he doesn’t realize that he’ll be the one amazed by how much someone can change.
I was breathing heavy. I could still feel my dad's cock inside me, throbbing strong, even after it had just filled me to the brim with hot muscle cum. I stared up at my father, my back pinned to the wall. I had never been more turned on in my life. He was covered in sweat, his massive hairy pecs glistened with the moisture. He just stared down at me, as his cock held me off the floor. His hands were wandering over my newly expanded body.
"I can't believe my cum made my boy grow like that," he said with a smile. His hands went under my arms and lifted me off his still throbbing cock. I hated the feeling of his dick leaving my hole. I felt so empty. I was addicted to the feeling of him inside me already. It was like my entire being was craving him. As my feet touched the ground, I looked up into his eyes.
"I love you Dad." I couldn't stop myself from saying.
"I love you too Son." he said with a smile as he kissed me hard and deep. Our tongue wrestling as I moaned into his mouth. "Now turn around, look in the mirror and flex for your daddy."
As I turned, I stared in amazement at my new muscle body, and the shreds of my shirt still wrapped around my arms and torso. My dad grab the shirt and ripped it off with ease. I know I grew taller, but seeing my father standing behind me, made me feel small. He was easily a foot taller then me. Clearly the workout of fucking me had helped him grow even larger. I lifted up my arms and flexed my biceps.
"Holy fuck!" I muttered. My arms had clearly grown to 19 if not 20 inches. I couldn't wipe the smile off my face. I lowered my arms and began bouncing my newly massive pecs. I couldn't get over their definition. I reached up and started playing with my nipples. It felt so good to play with them that I let out a slight moan. That's when I felt my dad push up against my ass. His hands roved over my new bubble ass, his cock leaking all over my crack. He pushed his fat cock into the valley between my muscle cheeks and began to kiss my neck as I continued to stare and flex. His hairy pecs felt so good against my back.
"You are so incredibly sexy son." he whispered into my ear as his tongue traced the out line of my ear. I let out another moan as I began grinding my ass back on him. My arm reached up behind me and grabbed my father's head. I started playing with his hair as he started grinding a little faster and harder into me.
"Daddy, I need you… I know you just came inside me, but I need more," I panted out, already short of breath. It was like my dad's mere presence was intoxicating. All I could think about was pleasing him, milking more and more of that muscle cum out of him. My cock was at attention, throbbing harder and thicker than I had ever seen. My other hand reached down and started to stroke it. Its girth was overwhelming. I couldn't believe it was my cock. My daddy's hands found their way to my pecs. He was massaging them, pulling on my nips, and twisting them. As his fingers danced across them, I moaned louder and louder, grinding even harder back on his steel rod of a cock. His muscle cock was like a faucet of pre cum. He took one hand off my pecs to stroke the head of his cock, which was mid way up my back. My father wiped up a large amount of his pre and held it in front of my face. I gripped his wrist and started to feverishly suck his pre cum off his fingers. It tasted like heaven and made me moan even more. One hand was feeding me pre as the other played with my nipple. My cock was now the faucet. I barely leaked any pre before my daddy filled me with his cum… now there was a puddle on the gym floor showing how excited I was to please him, to taste his sweat and cum. My dad looked down at it and let out a laugh.
"Damn, my baby boy is excited for more of me, let me get a taste of that!"
I let out a small squeal as my dad flipped me around and lifted me effortlessly up off the floor again. I didn't realize what he was doing until my head almost hit the ceiling with was 10 feet. He had power cleaned me clear to his shoulders. My back was against the wall, with my legs on his shoulders as my fat cock slid right down his throat. I thought I was moaning loudly before. As my dad's tongue played with my swollen head, I screamed out in pleasure. That's when he slid a finger into my cum filled ass. His finger was the size of a normal man's cock. I was squirming on his shoulders as he found my spot. the pleasure sent shockwaves through my body as he finger fucked my hole. My cock throbbed over and over in his mouth as he sucked on me. It was the best head of my life. I was seeing stars, uncontrollably moaning and screaming, begging for more. My dad slipped another finger inside me, fucking me hard and deep, nailing my spot over and over again. My back arched, eyes rolled back in my head. I was in pure bliss. he grabbed his cock and lubed up his fingers with all that pre cum and slammed back into me. I couldn't hold back anymore.
"FUUUUUCKKKKK DADDDDDDYYYYYY! I'M GONNA CUM!!!!" I screamed out. It only made my father suck on my cock harder. I unloaded the biggest load of my life. Not a single drop escaped my dad's mouth. He was as greedy for my cum as I was for his! That's when I felt the ceiling get a little closer.
FUCK! Can my cum make HIM grow!? I thought in amazement. Before I could even process that thought I was being thrown to the ground.
"Fuck boy! All that cum has turn me on so fucking bad!" My dad said with a grunt. He grabbed my head and slammed it into his crotch. My nose was smashed into his gloriously hairy balls. I took a deep whiff of his sweaty manly scent. It was the greatest thing I had ever smelled. I couldn't get his balls in my mouth fast enough.
"Fuck yes boy! Worship your daddy's balls!" my dad moaned. His hand never left my head as he rubbed my head over and over into his sweaty crotch. My tongue worshipped every inch of his balls as I stroked his massive shaft with both hands. I looked up at my glorious muscle daddy. I could barely see his face past the two giant mounds of hairy muscle that were his pecs. He was playing with one nipple as he humped my face.
"Fuck boy…. I love the feeling of that tongue on my balls." He moaned out. "Fuck you make me so god damn horny!" He pulled me off his balls and stared down at me. I watched as a smirk crept across his face. He held my face back, one hand on my chin, the other on my forehead as he spit into my open mouth. It was the hottest thing I had ever done.
"You're mine now boy." my dad said as he gripped his foot long cock and started smacking my face with it. He smeared pre cum all over my scruff. "Now you're marked." He smirked again as he slammed his gigantic dick down my throat. I choked, and gagged on its mass but I wasn't going to let that stop me. I ate his cock like I was starving. In fact I was. I needed that massive cock. I wanted that muscle cum. I wanted to taste it. I wanted to please my muscle god. I wanted to grow even bigger, to be just like him. My daddy let out moan after moan, grunting as he fucked my face without mercy. Tears were welling up in my eyes as he pounded my skull. He was raping my mouth. I tried to make him slow down but his hands were like a vice. He was 100% pure primal fucking my face. His cock felt like it was swelling even bigger with each thrust. I didn't know whether to be scared that he was about to crush my skull or so turned on I could cum without touching my cock. It turned out to be the latter. His alpha essence pushed me over the edge. My cock started to explode as he cock filled up my throat. I tried to moan but couldn't get out much more than a gargle. My father looked down as he felt my hot cum shoot all over his leg.
"FUCK BOY! TAKE MY CUMMMMM!" he grunted and slammed his cock deep into my mouth. His cock flooded my throat with hot sweet cum. I managed to swallow the first few shots but the shear volume overwhelmed me. It started leaking out of my mouth and down my chest as he shot stream after stream into me. I hurried to swallow over and over. The sounds that were coming out of my dad as he unloaded where nothing short of animalistic. I felt his cum warm my stomach. I felt the warmth start to spread again. I looked down as my arms and pecs began to swell again. I fell onto my back as the warmth engulfed my body. I moaned out and squirmed on the floor. My dad was still cumming, squirting more and more muscle cum onto me. I rubbed my expanding body, feeling the growth. I rubbed my daddy's cum into my pecs as I felt them compound under my hand. It was making me so hard. The power, the strength. It was amazing. I looked up at my father, I couldn't help myself, it was like his cum was viagra on steriods. I started jerking my cock at my daddy's feet, covered in his cum, muscles growing. He stared down at me.
"Fuck boy, you're growing even more!" he smirked. He started to flex for me. I felt my lats expanding, my shoulders getting broader. "My godly muscle cum is doing wonders for your son. Maybe one day you be this big." He said as he flexed a most muscular for me. I exploded all over him. I didn't stand a chance seeing that and not cumming. I just laid there at his feet, panting, covered in sweat and my daddy's cum. I couldn't believe it. I was hopelessly devoted to this muscle god. I couldn't get enough.
My dad extended a hand and I grabbed it. He lifted me off the floor with ease and pulled me into a hug. He pressed me against his hairy boulders of pecs.
"Sorry I got a little rough there. I don't know what came over me." He said with a blush.
"I loved it daddy," I beamed with a smile.
He kissed me deep, with passion only a father has for a son. He held me. I felt safe and warm in those impossibly strong arms. It was as though his essence engulfed me. I never wanted to leave. I looked over in the mirror. I was amazed at my transformation, but my father was on a completely different level. He was at least 7 feet tall now. His delts and shoulders looked like a literal mountain range. His biceps were the size of my head.
"Daddy you're huge!" I gawked. I stood back and just stared at him. He smiled down at me and raised his massive arms and flexed his mountainous arms. I grabbed his bicep with both hands i couldn't even come close to encircling it all.
"Look at how huge your father has become!" he said, as he flexed a most muscular. I swear I saw him grow even more as he flexed those gigantic muscles. I couldn't take my eyes off him. He was absolute muscle perfection.
"How is this possible dad!? Don't get me wrong, I'm not complaining," I said as I admired my own newly enlarged bicep.
"Well I found this at one of my work site's at the end of the summer," he said as he gripped his ancient looking necklace. I remembered how it felt hot against my skin when he was fucking me. I took it in my hand and rubbed it. It still felt hot to the touch.
"Any time I lift when I'm wearing it, it makes me stronger and grow bigger. It never made me grow this much before. But when I saw you looking so sexy in that tight shirt, it's like I lost all control and the necklace fed off my lust for you. I could feel it feeding off the sexual energy. It was so intense, all i wanted to do was lift, grow and fuck! Just thinking about it again is making me…. " I looked down as the necklace started to glow, and my dad's cock harden. I quickly lifted the necklace over his head. The action snapped him back to reality.
"Are you ok dad?"
"Yes boy, thanks. I needed to take it off, I don't know how I'm going to explain being this big… but the feeling is so addictive."
I smiled up, "It is an amazing feeling daddy! I don't know how I'm going to explain this either. I am definitely as big as Mitch now, if not bigger!"
My dad's face instantly changed.
"I need to meet this Mitch. Invite him over. I need to show him what real muscle is. He needs to know you're mine now, not his." he said in a deep growl.
"But… Daddy he's straight. Him and I have never done any…."
"NOW. Boy. I need to show him what a true muscle God looks like." My father said with such force I knew there'd be no debating with him. He flex his massive frame as he towered over me. I stared up at his muscles as the veins bulged. I had never seen anything like it. It made my knees weak. He truly was bigger than any bodybuilder I had ever seen. He pointed at our pile of shredded clothes. "Get your phone and call him now."
I scrambled to rummage though the clothes as quickly as I could. I was shaking. I didn't know why but I knew I had to. He wanted it, so I had to make it happen. He put his gigantic arm around me and pulled me into him as I scrolled through my phone to find Mitch's number. My father bent down and started sucking on my neck as his hands found my ass. I was intoxicated by his touch…. I was forgetting what I was doing… All I could think of was his cock inside me again.
"Dial the number," my father whispered into my ear as he lifted me off the ground again. His strength engulfed me. I couldn't believe how easily he picked me up. His muscles were so hard… So strong. The warmth of his body made me want more… No need more.
I pushed send as my daddy's cock slid inside me again.
"Fuck I love the feeling of my boy's tight warm hole," he whispered as he filled me up. His presence inside me was overwhelming, it pushed me to the edge of bliss but Mitch's voice snapped me back to reality.
