To help you get a clearer pictured things. I had a fit and hairless jock type build at 6’4 220lbs. Ivan is a massive and hairy  6’8 400lbs with naturally high testosterone and high steroid use. He also has a particularly severe case of hyperspermia.

This is my first story, there will likely be a second part. Any criticism and comments are welcome. 


I walked into the locker room after finishing my last set of deadlifts for the day and decided I’d check out how pumped up my back and arms were in front of the mirror, when I caught a glimpse of the biggest, hairiest, and most massive man I’ve ever seen in my life.

His entire body was covered in long jet black fur. He had a shaved head and a massive Viking-like beard. His swollen chest was so large it was practically in his face, he also boasted enormous traps and shoulders so big he had that no-neck look.

I then lowered my gaze to a huge, rounded, sexy, and firm “power belly” strongmen gut. I felt myself starting to stare so I quickly changed my glance off of the mirror and went to go sit in the sauna to relax.

A few minutes pass when I hear the sound of the sauna door opening, I opened my eyes and was greeted by that same mountain of a man I saw in the mirrors reflection earlier.

His frame completely filled the door as he walked in, our eyes immediately locked and he came down and sat right next to me, so close our legs were touching. Upon contact with his thick, sweaty, furry thighs my dick immediately started to stir beneath my towel.

“I am Ivan” uttered the man in a heavily Russian accent paired with deep voice as he extended a furry lunchbox sized hand.

“I’m Chris” I said,  softspokenly in sheer disbelief as I shook his hand.

It looked like a father and son, his massive calloused meaty paws and thick fingers dwarfed my hand in his grasp. My cock strained against the towel now, hot and throbbing as I felt myself doing kegels subconsciously as the “butt hunger” set in, I practically felt my ass self lubricating for this mammoth of a man I’ve known for no less than 5 minutes.

“I saw you looking. Did you like?” Ivan asked with a grin pointing at his fur covered pecs and bouncing them.

I shook my head yes because I couldn’t even form words and as I did he firmly grabbed the scruff of my neck, lifted his right arm up and shoved my face into his sweaty forest of an armpit.

I took a deep inhale of his musk and was immediately put into a submissive trance, I was effectively his at that point, the only thought that could pass through my brain is how desperately I needed to be taken by him, my cock now throbbing to the point of pain and my ass wet and soaked like a pussy and yearned to be taken by this masculine giant. Ivan could see things were reaching a point of no return so he sternly said “follow me” and left the sauna.

I quickly got up and followed him just as I was told without hesitation to a private room with its own bed and bathroom.

He locked the door behind us, picked me up and pulled me into a massive bearhug as I felt his strong tongue slide into my mouth, I instinctively spread and wrapped my legs around his massive bulk.

“I’m going to warn you, if we continue you will get big like me. No more skinny twink, my seed is strong.”

I didn’t know what he meant at the time, and I couldn’t care less the only thing I was concerned with is satisfying this titan of a man.

“I am yours, take me.” I muttered without a second thought. This answer satisfied him and immediately sent Ivan into a frenzy. In one motion he dropped me, bent me over the sink and plunged his thick tongue deep into my ass. The feeling of his big beard on my pussy felt so good. I looked up and got a glimpse in the mirror, I was a 6’4 220 lb. decently fit jock being completely dwarfed by a bigger more masculine man for the first time in my life and I felt as if I’d finally understood myself sexually.

I was born to serve massive masculine men, I now realized I wasn’t the pinnacle of masculinity I’d thought myself out to be. In reality I was just a small man capable of being completely dominated by someone bigger, and nothing turned me on more.

I moaned increasingly more submissively and passionately the further his tongue probed into my anal cavity. I felt his tongue pull out of me and I heard him say “Turn around” in his typical gruff tone.

When I did i saw a short and absurdly thick dick with the largest urethra I’ve ever seen perched on a fist sized cock head. He shoved me down to my knees to suck him and I started to get nervous at the thought of this massive daddy dick breaching my tight jock hole.

Ivan sees the worry on my face and smiles, “no need to worry I will make fit.” He said reassuringly, as he grabbed his boxers off the floor. “You see” he said pointing to the boxers.

I was extremely confused assuming something was lost in translation. He cupped the back of my neck and pulled my mouth towards his fist sized cock head and I could barely open my jaw wide enough to contain his thick girth when I felt him shove his boxers in my face completely covering my vision and nose.

“Sniff, deep” I heard Ivan say commandingly.

I took in a massive whiff and immediately his cock slipped several inches deeper into my throat with ease, his sweat and musk were more effective than poppers ever could be, it filled me with the immense desire to serve him in any and every way I possibly could. I started bobbing up and down on his jaw breaking cock with my newfound lust. He let out a deep sigh of satisfaction and said

“Good Boy.”

Who knew such a phrase could turn someone on so much. I stretched my jaw wide open as I could and slid the entire rest of his cock into my mouth until I reached the base and my head bounced off his big power belly.

Upon reaching the overhang of his masculine gut I lifted it up and pressed my nose into where his pubes met his belly and took another deep inhale. Once again his musk proved to be the ultimate aphrodisiac sending my head spiraling with submissive thoughts and turning my once tight hole into a wet hungry boy pussy.

“MMMMMMMMPHHHHH”

He groaned, clearly pleased that I was enjoying his scent so much.

I felt the helmet of his cock start to grow and his balls start to tighten I started to suck his dick harder and faster in anticipation of my delicious reward when

He pulled out, stood me up, turned me around, bent me over and pressed his fist sized cockhead against my willing and now soaked hole and applied pressure.

I started to whimper progressively louder as he pushed deeper into me, upon reaching past my sphincter i let out a scream that was quickly muffled by him stuffing his sweaty musky boxers in my mouth and bringing the rest to cover my nose.

“Sniff” Ivan commanded.

Once again I took a big hit of his masculine man musk as I looked in the mirror again. Seeing Ivan’s massive figure over me, my once tight jock hole was transformed into a fleshlight boypussy for an enormous bear of a man as he slid his cock into the base and I felt his masculine belly bounce off my balls.

“It has been long time since boy has taken me.” Said Ivan clearly visually pleased.

He pulled his cock fully out before plunging it straight back in.

“AGGHHHHHHHHHHHHHHHHHHHHHHHMMMMMMMMMMFFFFFFFHHHH” I screamed into the boxers balled up creating a gag as I felt my pussy stretch beyond what I ever thought possible.

He did it again, and again, and again with each thrust I fell deeper into my submissive headspace as I felt this Russian strongman completely wrecking my boy pussy.

He had me in a complete mating press at this point fucking me into the mattress like I was a petite woman, I felt his sweat cascading down his barrel chest and furry gut dripping onto my ass and back. As his power belly kept me firmly planted into the bed. Even if I wanted to, there would be no way to escape from the bulk of this beast.

After what seemed liked an eternity of having my ass pumped and prostate massaged by his gargantuan cock he pulled out and flipped me over on my back laying on the sink.

  “You will take my seed?” Ivan asked me hope in his eyes.

“Yes, please breed me, I’m yours PLEASE fucking cum in me”

Ivan was pleased. He laid my legs over his shoulders and put my hands on his pecs, telling me to “squeeze hard” before lining up his massive cock with my ass and pushing in.

The shock of having that fist sized head pass your sphincter never goes away.  I looked into his intense brown eyes and begged for his cum with all the sincerity in my heart.

The muscle giant started to stroke faster and faster. “You will be mine.” Ivan said, his eyes locked with mine.

I felt his grip on my legs tighten as he started thrusting harder and faster a clear indication I was about to be loaded up.

“AGHHHHHHHHHHHHHHHHHHHH” he exclaimed as he pumped copious amounts of his strongman cum into my wrecked boy pussy, I felt his warm seed filling me and was on cloud 9.

And then I felt him pump more and more and more and MORE cum into my ass for what seemed like minutes, he would thrust every few seconds and another rope of cum would shoot into me. He had given me so much of his seed my stomach was now swelling as if bloated after a massive meal.

After several minutes of cumming he turned me around and laid his big body on top of mine and we made out for awhile before Ivan said “You will be big tomorrow”

I didn’t know what he meant in the euphoric haze I was experiencing but I didn’t care. Being turned into a submissive bitch and bred by this bull of a man was the happiest experience of my life so far.

I drifted to sleep, cradled and protected by Ivan’s massive hairy arms. As he gently rubbed my seed-filled ass.

I woke up extremely well rested in a still euphoric mood and rolled over to check my phone to check the time.

15 hours? I’d slept 15 hours? No wonder id felt so good.

I got out of bed to take a piss passing a mirror on my way when I was forced to have a double take at my own reflection.

My typically hairless body now sported dark and thick fur developing on my chest, tummy, arms, and face. “I have a fucking beard?!” I said aloud to myself.

I think Ivan took this as a sign I was awake because I heard his giant footsteps start to thunder towards my side of his apartment.

“Hello, my boy” Ivan said in his gruff voice as he came up behind me and grasped my still bloated belly firmly with both of his thick hands.

“Ivan what is happening to me?” I asked

“My seed is strong. It makes boys into men. You will grow big like your daddy” he said, rubbing his furry belly.

“Now boy, it is time for morning protein shake, get on knees.”
