The power of bondage

by Writ Bro   

A curious sub encounters a strict BDSM master who sees a lot of potential in the young man’s currently ordinary appearance.

It was a cold rainy winter afternoon. Just a regular Sunday, on just any weekend in the new year. I was bored at home and had nothing to do. I had already cleaned the house top to bottom, did all my laundry and was bored.

I was keen to be sociable but all my friends seemed to be out of town that weekend and there was really no one to hang out with. So I did the usual.

I opened Grindr.

It was something I had done many times before. It’s something I never really enjoyed but did out of habit more than anything else. I had only hooked up with guys a couple of times and never found it particularly gratifying. But I went for it and had a scroll to see who was new in my area, or if it was just the usual bunch of people. To my surprise, there was someone new, about 2 miles away.

The picture showed a buff body, without a face, clad in a leather harness, with straps tightly fitted over biceps and leather gauntlets covering his forearms. I clicked on his profile and saw he was only about 28, 6’5”, 320 lbs.

Now I didn’t really know if that was impressive or not. It certainly looked like quite something. I got excited, both by his physique and by the accompanying leather gear. So I sent him a message.

“Hey”

He only took a moment to reply.

“Hey boy”

The tone was immediately set. We talked the usual small talk before he asked what I was looking for.

“I was bored tbh”

“So what made you talk to me?”

“Ehm. Your big physique mostly”

“Mostly? So what else?”

I hesitated, but eventually replied.

“Your leather gear, Sir”

“And are you a sub?”

“I guess so Sir”

“I am certainly impressed with your manners, addressing me properly as Sir.”

“Thank you Sir.”

“Why don’t you come over right now, and I can show you the ropes?”

I hesitated for a moment, but quickly decided I wouldn’t have a chance like this one again for a while. So I got dressed and went to the address he gave me. I drove into a nearby neighbourhood that was definitely posher than mine. I parked on the driveway of his large, stately home.

I rang the doorbell and remembered his instructions. He had told me to wait until the door opened, even if it took a long time.

And so I waited. I looked at my watch and I easily stood there for 10 minutes. I heard some noise. I opened Grindr, but the profile had gone. I waited patiently for another couple of minutes.

After about 30 minutes the door opened. A tall man showed up. I realised I hadn’t seen his face yet, or even know his name and I started to panic. But at the same time I was immediately in awe.

In front of me was the most beautiful man I had ever seen. I took it all in, with big, massive feet at the very end of the biggest tree trunk legs I had ever seen in my life. As my gaze moved upwards, I noticed the incredible strength he must contain in his humongous quads. His crotch made my jaw drop even further as I see a huge bulge poking out at the front of a leather jockstrap. His abs must have been the best carved eight pack I had ever laid my eyes on. And the shelf resting above it was held in place by the harness, bulging underneath the tightness of the leather. “Fuck,” I whispered, admiring the huge muscle tits.

And then there were the biceps. I had definitely never seen biceps like those. The strain of the leather straps suggested that they were probably made when his biceps were a few inches smaller.

To top it all off there was the face. A beautifully chiseled jawline, with incredible cheekbones, piercing blue eyes and strawberry ginger, curly hair.

He smiled.

“Welcome boy. Come in.”

I was immediately hard and followed him into the house and admired the beautiful surroundings. It looked luxuriously furnished, with incredible works of art.

“I am Michael, boy. But you shall call me either Sir or Master. Understood?

“Yes Sir.”

“Good boy. I will call you boy or slave. You are mine for the rest of the day or until you use the safe word. To end the session you simply say ‘circus tent’. If I am about to initiate a specific session you do not wish to do, simply say ‘fish tank’.”

I smile at the ridiculousness of the words. But it made sense, in a BDSM situation they are vital and I simply nodded to acknowledge I understood.

“Good boy. Now, let’s get you dressed first.”

Master took a collar out of a nearby cupboard and put it around my neck, locking it into place with a padlock, followed by a leash. A strong tug and I feel my neck been pulled down as he dragged me into a large room upstairs.

The room was dark, in the centre of the house. It could have been a basement had I not just gone up some stairs. It was sparsely lit, with only a couple of lamps on the walls that caused ominous shadows to fall around the room. I looked around the room and saw some incredible bondage equipment. A leather-clad St. Andrew’s cross was on the far wall, with a revolving bondage wheel on another, with at the centre of the room a large cage, maybe 3 or 4 feet high, topped off with a leather bench. Closest to me was a sling suspended from the ceiling.

“So slave. This is where you will spend the rest of today. You like it?”

I simply nodded.

“What was that, boy?”

“Uhm...” I hesitated. “Yeah.”

“Excuse me, boy?” All of a sudden I felt a rushing pain through my butt, as I see Sir has taken out a paddle and swatted me on the ass.

“Yes Sir. Sorry Sir.” I said immediately, the pain stinging even through my jeans.

“Good boy.”

He tied my leash to a hook on the wall and walked out of the room. He knew I could untie it myself, but he also knew I wouldn’t. I was too desperate to worship him.

He walked back in with a small sports bag.

“Strip,” he ordered.

I did as he told me, removing every item of clothing obediently. First my jeans, followed by my hoodie and button up shirt. Last to come off were my jockstrap and socks.

“Nice body, boy. And nice hard cock,” he added.

I smiled at his compliment yet struggled to believe him. I am just a plain, average guy. 5’9”, average body, average cock with no hints of muscle, but not a lot of visible fat either.

“Hold out your hands.”

As I hold out my hands he put a bondage mitt on each of them, followed by a small leather thong, a harness and bicep straps. It’s like Master was trying to mock me and my puny body.

“You have a nice body for someone as young as you. But I think we can do better.”

I guess I have an average body for a 23-year-old. But I had no clue how he was planning to change that.

He put me in a blindfold. “We’re going to start with some bondage boy.”

I could hear him unclip the leash from the wall and drag me across the room. He pushed me down on a soft leather padded surface. “It must be the cage,” I thought to myself.

I could feel him guide me into a lying-down position. First he clipped the mitts in place, preventing me from moving my arms. Then, I felt thick, padded restraints wrap around my ankles, my legs slightly spread open.

Suddenly I felt hands on my cock. A thin rope was used to tie up my dick, with my balls pulled down tightly.

Everything went silent. I start to shiver and shake with fear but my cock was still throbbing hard.

It must have been silent for a long time because as I was laid there, I heard nothing, just the beating of my heart.

After a while I got frightened and started to struggle. After a longer while I got tired.

I must have fallen asleep. I woke up from a sharp pinch from my groin.

“Ouch!” I screamed.

“Ah you’re awake. I thought that would wake you up.” Master said.

“What are you doing?”

“Oh, nothing. Just a bit saline.”

“Saline? What’s that?”

“It’s a salt water solution used to temporarily inflate your scrotum,” Sir said, very matter of factly.

“Why are you doing it?”

“Because, it is the first thing I do to subs. Give them a bigger set of balls.”

“While you are playing with them?”

“Well that is the purpose of it, yes.”

I considered using the safe word but the inflating feeling coming from my balls was surprisingly comfortable and I fell back asleep.

When I woke up I had no idea what time it was. I could have slept for hours or just 30 minutes. As I reached consciousness my body felt different. It felt new. I tried to move but noticed I was still tied up. The blindfold had come off. I look down at my dick and suddenly realised I couldn’t see it. I panicked and started to scream.

I seemed to scream for a long time, but eventually the door opened and there stood my master, his beautiful body glistening and pumped as though he had been working out, wearing a pair of very short sports shorts.

“I see you have woken up. Why are you screaming?” he asked, in a surprisingly calm tone.

“M-m-m-y c-c-c-o-c-k” I stammered.

Master looked confused.

“I-I-I can-t-t-t s-s-s-ee i-i-i-it”

And suddenly he laughed loudly. Not an evil laugh, not with menace, but as though he had actually heard something funny.

He proceeded to undo the restraints, left the mitts on my hands, and told me to stand up.

“Come with me boi.” He took me by the hand and guided me across the room to a full length mirror.

“This is why you can’t see anything boi.”

I looked at my reflection and my jaw dropped.

In front of me was a completely different guy to the one I had known. I had grown into a full muscle beast. My biceps had inflated to the biggest guns I had ever seen (besides those on Master) and my pecs were the reason I hadn’t been able to see my dick. They may as well have been bowling balls for the incredible size they were. My abs were deeply cut, as if out of marble, with six perfect slabs on my stomach. And underneath that the most incredible thighs and quads I had ever seen, with veins popping out, perfectly accentuating each crevice and line. They looked more chiseled and sculpted than any pair of legs I had admired. And in this case it included master.

“You like what you see boi?”

“I love it Sir! But how is it possible?”

“Well I am a scientist and years ago discovered a mixture that would allow anyone to stay muscled as long as they took a single dose of saline infused mixture in their balls. The saline is absorbed by the body, and in this case so is the added mixture and the mixture triggers the body to grow.”

“Can you only use it to make the body grow Sir?” I asked curiously.

“I discovered a few other mixtures along the way. All need to be dosed in the same way once.”

“How many doses have you had Sir?”

“Just one of the muscle one and one cock one. But I have more plans for you.”

I looked at him curiously.

“It’s voluntary don’t get me wrong. But as soon as you walked through the door I thought you would be the perfect guy to try this on. Your body is the perfect combination of slim and having the frame to cary the muscle on.”

“And what would you want me to do?”

“Well—it wouldn’t be today. You would have to agree and we can decide how we sculpt your body.”

I was listening with great interest.

“So you didn’t invite me here to use?”

“Oh I did. I had no idea how perfect you would be.”

“So how would this work?”

“Well—I own your cute ass. I do today and I will do while we do this programme of growth. But we’ll put together a programme based on the mixtures I have made and what they do and we go from there.”

I liked the sound of it. I was really excited actually. So excited my cock started go hard. And of course Master noticed.

“I see you like that don’t you?”

I nodded shyly.

“On your knees boi.”

I obeyed him without hesitation. I got on my knees and waited for his orders.

He came up to me, his crotch directly in my face. He dropped his shorts to his ankles to reveal a huge bulge in a well-filled sports jockstrap. He pulled down the thick white waist band and slowly let his cock unroll.

And unroll really was the best word for it. The thick snake fell out of its pouch to reveal its gargantuan length and thickness. It must have been at least 10 inches, still soft, and maybe 7 or 8 inches thick.

“Fuck” was all I could say.

“Suck it boi.”

I hesitated. How could I suck something so big. But then I realised—why would I let a challenge like this one slip. I took his huge purple head into my mouth and was surprised to notice my mouth stretched fully around the circumference of his cock. Slowly I slipped in more of the monster, letting it get deep into my throat until I felt it hit an invisible wall.

Master took my head with both his arms and started to fuck my face. I choked but was able to take half the length of his cock as he fucked my face harder and harder.

“Now boi. It’s time you take the entire length”

I realised I had a scared look in my eyes as I looked up at Sir. He had wicked smile on his face.

“You’ll be fine boi.”

And with that he started to really go to town on my throat. With each stroke he pushed harder and harder. I had only been fucked like this in my ass but never had anyone abuse my mouth so much. I was in pain and agony and yet I could feel my own rock hard cock dangling and dripping between my legs as he managed to shove more and more of his huge cock down my throat. Fully hard, it must have grown to 15 inches and at least 10 inches thick. But I must have had 10 inches down my throat easily and noticed my nose getting closer to his pubes with each thrust.

“Come on boi. You can do it, come on!”

His confidence in me put a slight smile on my face and I must have relaxed a bit because suddenly another three inches slid into my throat. I could almost feel my throat expanding as his cock invaded my body. Then, Master grabbed my head tighter than before and really pushed and to my amazement I could see the remainder of his cock slide in.

When his balls slapped against my cheeks he patted me on the head.

‘Well done boi.” He said. “We’re going to keep it here for a little bit okay?

I looked up and he smiled down at me. He kept a firm grip on my head, refusing to let me go as I start to choke uncontrollably. Suddenly I could feel his dick swell up and start to cum down my throat and shot after shot of cum came out of cock, for me to feast on. When he finally stopped coming, he pulled out, making me choke a couple more times before my body relaxed.

“Very well done boi. No one has ever taken my cock like that before.”

“It was a pleasure Sir” I said to him.

And I meant it. My own cock was rock hard.

As soon as my throat had relaxed, I feel a leathery feeling around my neck as my Master put a collar back onto me.

“Now boi. You will wear this when you’re in this house, understood?”

“Yes Sir.”

“You must remember whose property you are. Because of that, I will put you in chastity when you are not in this house. You will wear it all day, every day when not in my presence. And maybe sometimes when you are in my presence.” He laughed, knowing that there was no way he could get me into chastity with the ridiculous hard on I had at the moment.

“Yes Sir.”

He lifted me to my feet by grabbing a strong hold of my collar and despite my new found muscular form it was clear he was still the stronger one.

He dragged me along the room to the sling and pushed me into the soft leather, forcing me to lie down on my back. He grabbed each foot and put them in restraints.

“Ready for this slave?”

I gulped. I knew what he wanted to do but was terrified of the prospect. Master grabbed some lube and lubed up his huge cock and put it at my very tight hole.

“I will take it slow.”

And that is what he did. Although I half expected him to just shove it in, he actually gently pressed his cock into my hole, allowing his premium to lube me up gently. As he pushed harder and harder, I felt my hole stretch open wide to accept his massive member.

“Oh fuck” I said in the middle of a gasp as I tried to relax.

“It’s okay boi. Your new body is capable of taking this, I have made sure.”

I believed him and managed to relax more. More and more of his cock entered me and I could feel the pressure on my ass mount. It felt incredible and yet so painful. With each push, half an inch, or maybe an inch would slide in, stretching me open wider and filling me more than I had ever been filled before.

I was shocked to see I could even see a slight outline of his cock coming through my abs.

“FUUUUUUUCK” I screamed even louder this time.

“Fuck take it boo!”

Although Sir wasn’t all the way in yet he started to actually fuck me. He grabbed hold of my waist and started to pound into me. Each stroke loosened up my hole, allowing him to shove more of his monster into my destroyed arse.

“Fuck yes Sir. Oh yeah, fuck me!” I screamed in ecstasy.

“Such a good boy!”

And then I felt it.

His balls hit my ass.

I looked down at him and saw 15 inches of cock bulging underneath my abs. And then it started to slowly retract as Master pulled out.

And he slammed it back in with full force, making me scream and whimper.

With each stroke I moaned louder and louder, unable to keep quiet with the intense sensations running through my body.

Suddenly the speed of Sir’s strokes increased even further and I knew he was about to cum. With an incredible explosion I could feel his seed shoot into me, streaming into me with amounts I would not have imagined possible. Sir pulled out, only to replace his huge cock with an even bigger buttplug. And it felt like it could fall out, that’s how loose I now was.

“You better keep that in bio or otherwise you’re in trouble.”

I clenched my ass around it, doing my best to keep it in.

Master had locked my cock in a chastity cage and told me he would know when if I took out the butt plug. I was allowed to remove it three times a day to go to the bathroom but otherwise it had to stay in. And with that simple message he told me to get dressed and go home. Without even cumming. I would get a text when he next wanted to see me. And I’d better be free.

Once I was home I went into my bedroom and looked in the mirror. I admired my new body and slowly start to strip for myself, removing my top first, revealing my big bulging biceps. As I flexed I noticed my pecs move and I tried to bounce them individually myself. As I noticed them bounce back and forth I felt my cock twitch, sensing I was getting turned on by my own locked-up cock.

I realised quickly I couldn’t keep doing this to myself, or I would never go to sleep. I decided to jump into an ice cold shower and as the water ran through the new-built crevices of my muscular body I could feel my dick relax and my attempted hard on seized its efforts to gain freedom. I lathered my body up with soap but conscious that I could get horny again I did it quickly. I turned off the water, dried myself and went straight to bed.

I slept... oddly. It wasn’t bad but throughout the night I had multiple, extremely vivid dreams. It started off by reliving my growth experience earlier, but this time I was fully aware of the growth happening as I was asleep. At first it was painful, with the pain spreading from my balls into my body as the saline was absorbed. The next minute I felt my biceps pulse as the veins expanded. As blood rushed through them I could feel them grow bigger and stronger with each heartbeat.

Only a moment later I was in a white and sterile room. It felt like a hospital. A man was bent over the bed and taking measurements as I laid there, vast asleep. My balls felt heavy as though they were full of saline and I was shocked as I saw a nurse lift them into my own view.

The dream changed again. This time I was in a shop. I had a collar on and master was right next to me as a woman measured my chest. I heard master laugh and as I looked around I saw bras and lingerie in the window.

And this went on through the night. The dreams confused me and when I finally woke up I was covered in sweat, my locked cock dripping.

I looked at my alarm and noticed it was about time to get up. Usually I would have a wank at this point but since I couldn’t I went straight for the shower.

Even as I walked into the shower I could feel the butt plug move inside me, sometimes hitting my prostate as my feet hit the ground.

Once the sweat had washed off I started to get dressed. As I open my wardrobe I realised my clothes must all be too small. “Fuck,” I thought to myself. “What am I going to wear...”

I had to try something. I pulled out one of my usual shirts just to see how it looked and as I pulled it on it was as though I felt the sleeves expand to accommodate my bigger arms. I start to do up the buttons and as I went up I could feel the fabric expand to fit my huge lats, the shirt forming a perfect V around my muscled body.

I had to try this with trousers.

I grabbed a pair of my favourite suit trousers, that usually showed off my ass quite well. I pulled it up my legs and as the trousers climbed up I could feel them grow to make space for my tree-trunk legs. When I reached my ass I felt it really expand and my new, humongous bubble butt strained the fabric even as my trousers attempted to contain the massive slabs of muscle. It wasn’t until I did the button up that the final stretch was provided to fit all of me.

I looked in the mirror and admired my muscled body, loving the look of the tight clothing covering it. I felt my dick twitch and to my slight horror I saw my bulge was clearly visible. “FUCK!” I thought to myself. “There’s no way to hide that.”

It had to do, I thought to myself. And with that I grabbed my suit jacket and some breakfast and left the house.

At work everything went surprisingly smoothly. No one commented on my new size but instead I got compliments all day on how good I looked. I was over the moon as I had never felt so good about my body before and the day flew by. Even the buttplug couldn’t slow me down.

At home I was a bit lonelier. I didn’t want to meet up with friends in case master summoned me and I really did hope master would summon me.

But it didn’t happen. I spent the evening admiring my body and browsing the internet. My boredom diverted me to porn but as I couldn’t wank all I did was wind myself up. By now the plug in my ass wasn’t helping and I was desperate for some release.

The next few days were very much the same. Each day I tried on clothes I hadn’t had on since discovering my new body and they would expand to accommodate my immense muscularity. And each day I went home after work to discover Master had not summoned me. I was growing impatient.

By Thursday I decided to fuck it and went for a couple of drinks with my buddies. I stayed out late and despite having a good evening I still looked out for texts throughout the night. I didn’t think my buddies noticed any changes and after a number of pints I called a cab to go home, stumbling drunkingly into bed.

My problem was that now drunk, locked and plugged, I really felt horny. And there was still no release in sight. I started to get desperate and tried to hump the plug but nothing seemed to help. I eventually fell asleep and experienced another night of crazy dreams.

It wasn’t until Saturday morning that I finally received a text from Sir. But it wasn’t what I hoped for.

“Sorry bitch. Really busy. You’ll have to wait.”

I simply replied, “Okay, Sir. Awaiting orders.”

It took him two hours to reply to that. “Go to the gym boi. Jockstrap, lycra tights, tank top, and shoes only. Every day.”

And there it was. I was given a task to do and that was it.

I went to my local sports store and bought the necessary items. A jock I had but I had never had the confidence for lycra or a tank top before. Even now I was hesitant but I followed master’s orders.

I had a gym membership but I hadn’t used it in a while. It was a nice, spacious and well lit gym in my neighbourhood and I was happy none of my colleagues were members. Especially when I realised that both the lock and the plug were quite visible.

But I pretended they weren’t there and started to work out. To no one’s surprise I felt incredibly strong and was impressed by my own ability to lift. I spent a good two hours in the gym both that Saturday and Sunday but made the conscious decision to shower at home. No need to show my actual plugged ass and cock to anyone if I didn’t have to.

On Monday came the next text. “Take some pictures each time you’re in the gym. And you better shower there.”

Well there goes that I guess.

So I went to the gym and took pictures of me in my sports gear. I had to admit I looked good but I was slightly embarrassed by the outline of the chastity cage underneath my tights.

I got really embarrassed when I walked into the showers and started to strip. It was relatively quiet but there was no ways the few guys in changing room didn’t see my locked cock or my plugged ass. I knew immediately that I was bright red but I went along with it and started showering.

In the steam filled shower room I could feel guys looking at me, taking glances and some desperately longing stares. I wanted to get out quickly but as I walked out I felt one hand cup my cock for just a moment, but I really flinched when I felt a hand suddenly spank me.

I practically ran out and quickly got dressed and rushed home.

And the next day I did it again.

And again.

Each time I sent a picture to Sir I got a reply saying I had done well.

And it must have gone on for another week.

It wasn’t until the two weeks and two days after I had seen Master that he texted me telling me to meet him.

I was told to meet him at a large, almost abandoned car park at 8pm, after work. I had to go to the gym beforehand but I was not to shower afterwards. Instead I was to keep my sports gear on and I was not to have eaten.

Of course I did all he told me to do.

At 8pm I met him in the empty car park. His truck was at the other end and I drove up and parked next to him.

“Just on time boi. Perfect.” He said as he walked up next to the driver side. “Get out.”

I did as he said and I stood in front of him, relaxed, glad to see him again. A familiar face despite having met him only once.

“You’ve done exceptionally well boi. I hear from the guys at your gym that you shower naked and that everyone now knows you wear a chastity cage and a buttplug. You’re doing really well.” His smile was friendly and kind.

“Thank you Sir.” I said, very pleased to hear that he was happy with me.

“Now tonight I wanted to try something different. I wanted to see if I could grow you in public.”

“I wanted to see if I could grow you in public.”

“What do you mean Sir?”

“Well the last time you grew in your sleep. This time I want you to be in a room full of people as it happens.”

I must have had a confused look on my face because he laughed.

“Don’t worry, it’ll be gradual and any muscle group we agree on.”

I gulped. I didn’t expect this to be the next step.

“Come on, in the back of the truck.”

He opened the back of the truck and I jumped in.

“Lower the tights, boi.”

I did as I was told and immediately he got out the saline kit.

“What muscle group do you want, boo?” he asked.

“What about thighs?” I asked him back.

“Let’s start with your upper body slave.”

“Okay… pecs I guess?”

“That sounds like a good idea. We’ll insert the saline here and then head off. We’ll activate the mixture once we get to our destination.”

I noticed him fumble for his keys and he undid the chastity cage.

Then he grabbed one of the fluid packets, gently inserted the needle into my scrotum and started to insert the fluid.

After a while my balls swelled up substantially, but not outrageously so.

“Right that’s it. Now to let your body absorb it. Jump in the truck, boi.”

And so I jumped into the passenger seat of master’s truck.

“Put those clothes on, boi.”

On the seat was a tight, short sleeved v-neck tee and a pair of jeans. I put on the tee and noticed how tight it was on my body. I started to take off my tights but Master was quick to stop me.

“Jeans over the tights, boi.”

I put the jeans on over the tights as master drove around. Eventually we pulled up by the mall near the centre of town. The car park was packed and as we parked I could see I would be very much on display here.

“Sir. This is a family friendly place. Is this really the place to get people to watch me grow?”

“It’s 8.30p.m., boi. And the mall has a ‘date night’ promotion on. It’ll be full of couples.”

He grinned. I immediately got nervous. Fuck, I thought to myself. This could be really bad.

We got out of the car and master grabbed my hand. Hand in hand we walked into the mall, looking like any other couple. Besides the fact most of them were straight.

We sat down in one of the busy restaurants in the food court. People were at all the tables around us. Master ordered some water.

While I looked at the menu I tried not to pay too much attention to my surroundings. I selected something absent-mindedly and told master my order for when the waiter arrives. He is in charge, so he ordered the food.

When the waiter arrived, Master ordered the main course. He quickly put a sachet of some sort of powder into the water.

“It will activate the saline,” he said reassuringly. “Now down it.”

Within seconds my glass was empty and I started to anticipate the impending growth.

Within a few minutes I feel a strange tingling sensation in my stomach. And then the sensation spread upwards.

Before long the food arrived, and so did the growth. I felt my pec muscles flex involuntarily. First together and then one by one. With each flex the feeling got stronger and eventually I felt a twitching pain with each flex.

I tried to pretend it was not happening but I was sure my tight tee showed off each bounce as they happened.

I took a bite to eat of my chicken fillet. Master had wanted me to get something rich in protein.

Without warning I suddenly felt an intense pain in my crotch, as though I had been kicked in the balls. I almost screamed with the pain but I managed to compose myself.

I was sure master knew what had happened but he merely smiled.

“So how was your day, boi?” he asked me.

“Well, thanks.”

I noticed he grimaced.

“Well, thanks, Sir.” I corrected myself. “Busy, but nothing strange or out of the ordinary.”

He smiled. Then it felt like I was again kicked in the balls. This time my reaction was more intense and almost collapsed in my chair, having to hold on to the table to avoid falling on the floor.

Master simply looked on, apparently unfazed by my pain.

And then it really started. The twitching pains in my pecs started to rapidly bounce back and forth.

“Sit normally and eat.” Master whispered.

I pulled myself together and just about managed to sit normally and pretend I was okay. But the pain continued to shoot through my chest and as I looked down at my food I saw my pecs expand. Slowly but surely they were growing bigger, the tee becoming more strained and tighter with each twitch.

When I sat down at the table and I sat up straight I was just about able to look down and see the edge of the table. Now I was no longer able to see the edge of my plate. And the growth hadn’t stopped.

It also looked like several of the patrons in the restaurant had themselves noticed something had changed about me. No one was necessarily staring but occasional glances betrayed their curiosity.

And then the twitching pain trailed off. And within moments I knew that my pecs had stopped growing.

But suddenly the pain in my groin returned. More subtle this time, but I could feel the pain almost flow from my balls through my cock and back. I restrained myself and tried to show no obvious sign of my suffering.

The pain flowed around for maybe 5 or 10 minutes. My lycra was feeling increasingly uncomfortable. But I finished my meal and Master generously paid for both of us.

By this point the pain had subsided.

“Ready, boi?”

“Yes Sir.”

He stood up and I followed his lead. As I stood up my own jaw dropped. Even beyond my huge pecs I was able to see a hint of the bulge I was noe supporting. There was no doubt what had happened. My cock and balls had also grown. Master had wanted to grow more than just my pecs and not told me. And I was immediately turned on.

Of course I wasn’t the only one to notice and people looked me and almost laughed, until they saw the whole bulge twitch with excitement and realised it was all real.

We strolled back to the car, Master keen to take our time. People kept staring at both my crotch and my huge pecs, eyes rapidly darting between the two.

He dropped me off back at my own car.

“In the back of truck with you before I let you go.”

I obeyed, unsure what to expect.

“Remove the jeans now.”

I removed the jeans, the bulge in my lycra tights obscene and gargantuan.

“Looking good, boi. You did really well tonight, I’m proud of you.”

“Thank you, Sir.”

“But rules are rules. Let’s get you locked up.”

I was surprised. I thought Master would want to lock me back up but I didn’t think he could. The size of my cock had to be too much to hold.

I wasn’t entirely wrong. Master took at several thick steel rings and started to manoeuvre them around my cock. I looked down and realised it had to be at least 12 inches soft. I’m bigger than Master, I thought to myself, quite surprised.

One ring fitted just over the head, where it was just a bit too tight to be comfortable. Another fitted at the bottom of my balls and a third at the base of my cock.

With two small padlocks he locked the ring around my head to the ring around my balls and the ring around my balls to the ring around the base. There would be no way of getting this off and it would be very uncomfortable.

“Friday evening, 7 p.m. at mine. Prepare to be with me the whole weekend.”

And so, dressed only in the tight tee and my lycra tights, butt plug still in and cock once again locked, I went to my own car and drove home.

Once I was home I realised it was quite late and I better get to bed. But I couldn’t help and stop to admire myself in the mirror. I stripped of the tee and tights and admired myself in the mirror. My pecs had really grown.

“Fuck” I said to myself.

They had really grown.

In fact, they started to look like TITS. I couldn’t help make the comparison, even if I didn’t want to.

“FUCK FUCK FUCK” This was almost a step too much. I was tempted to text Master and let him know how I felt. But this wasn’t the time. And I remembered the other change that had happened.

I looked down at my cock and spread my legs. Looking in the mirror it was obvious how hung I now was. The feeling of my huge balls and schlong dangling between my legs was amazing, only emphasised by the metal rings locking my cock in place and pushing my bulge out.

I was doubting which I preferred. Having neither the cock or tits, or having both...

The decision was really not that hard. This cock was amazing, even if it was locked. The tits I could get used to. I looked into the mirror and bounced them back and forth. It actually looked quite good.

I started to pose a bit more. I had never done this before but I had looked at the occasional bodybuilder picture and video and just did what they did. First showing off my biceps, the bulging veins and crevices popping up and deepening as I flexed. I tried a most-muscular, and it felt my pecs were going to explode under the pressure I could feel in my chest. And my god it felt good.

I got so turned on watching myself flex in the mirror I could feel my dick getting harder. FUCK. It started to really hurt, the chastity keeping my cock firmly down and giving it no opportunity to grow.

Swiftly I decided to hit the sack. I really didn’t want to deal with an intense horn all night. Although that seemed pretty inevitable, having not cum for almost three weeks now.

And so I went to sleep. I discovered my newly grown pecs, despite their hardness, were surprisingly comfortable pillows and my now huge cock just nice dangled between my legs, hitting the bed when I was lying on my side.

When I woke up the next morning I had a text from Master.

“Forgot to say boi. Make sure you go to the gym as usual. The tee I gave you will do nicely to wear while working out. Same rules as previously!”

“Here we go again,” I thought to myself. I had to go to the gym wearing my lycra tights, tee, chastity and butt plug. This would be fun.

I discovered that my clothes again shaped to my new body. My favourite work shirt wrapped itself around my man-breasts without any effort and moulded in such a way as to perfectly show the beginning and end of my pecs, almost making the veins visible through the fabric and definitely emphasising both nipples. The only thing was that it definitely felt a bit tighter than before, as if it had grown the minimum amount to fit, but not quite be comfortable.

I looked incredible.

And so the next few days my routine went back to normal. My intense drive for work had not gone away and the days seemed to fly by. And now that I knew when I would see Master, I was extremely excited and keen to serve him as best as I could.

My visits to the gym remained unchanged, except the fact my bulge was far more obvious than previously and the strain of the tee was intense, almost distracting. I could feel it being stretched to the very limit each time I worked on my chest.

I had decided not to be annoyed about my tits. They actually looked incredibly good the more I looked at them. I wouldn’t even mind growing them just a little bit further. And so I continued working them in the gym.

My colleagues seemed to be increasingly in awe at my body. They didn’t notice my ridiculous bulge, or my oversized pecs specifically, but instead I seemed to have more and more women (and men) lusting after me.

On Friday I had the chance to leave work early, so I decided to go to the gym quickly before going to see Master. After a good hour long workout I drove to his place in my gym gear, unshowered and rang the doorbell.

I hadn’t received any other instructions but to be there for 7pm. I was there perfectly on time but remembered from last time not to expect the door to open immediately.

I stood there for maybe 10 minutes when I felt my phone vibrate.

“Strip boi,” read a text message from Master.

I gulped. I had to strip out in public view? That was another level.

But I obeyed, keen to satisfy Master.

“Fold the clothes up in a pile next to the door,” read the next message.

Swiftly I obeyed again, neatly folding my gym clothes and leaving the right next to the door.

Now naked, locked in a chastity getup and a plug in my ass, I stood waiting in front of the door. Plenty of people could have seen me if they paid attention. But the road seemed quiet so I hoped no one saw.

After waiting for another few minutes the door opened. And there stood Master in all his glory, just a leather jockstrap and harness. I immediately wanted to get on my knees and worship.

He motioned for me to come in and being the good boi I am, I obeyed happily.

“Well done boi. Perfectly on time, and perfectly followed my orders.”

“Thank you Sir.”

“Have you had dinner?” he asked me.

“No Sir, not yet. I came straight from the gym Sir.”

“I thought you would. I have some food ready if you fancy?”

“I would love some, please Sir.”

He rummaged around in the kitchen. “Chicken with brown rice and some soya sauce.”

He walked towards me with a metal bowl. It looked like a dog bowl. And instead of putting it on the table he put it on the floor.

“Now come here boi.” He said, motioning for me to come over.

I walked over.

“DOWN BOI,” he suddenly shouted. I immediately got on all fours, kind of scared.

“Now come here,” he said again.

I crawled towards him and waited in front of him. He grabbed a leather collar from the counter and put it around my neck.

“You’ll wear this all weekend boi. Is that understood?”

“Yes Sir,” I nodded.

“Now eat.”

And with that he grabbed my head and shoved it into the bowl.

I ate greedily, absolutely starving by this point. Within a minute I had practically licked the bowl clean and forgotten about all my sensibilities. I was Master’s slave now and this had firmly put me in my place.

“Good boi,” Master said when I had finished. “Now come upstairs.”

So we went upstairs, into the darkly lit dungeon room.

“Here boi.” He motioned me to come over to the immense rotating bondage wheel. He grabbed each of my wrists and ankles and tied me to the wheel, my locked cock and tits facing out.

Without warning he began to spin the wheel, lowering my head slowly until it reach the height of his cock. I was roughly two thirds of the way down when Master began to insert his huge dick into my mouth.

I struggled more than before, unable to align my throat properly to give him full access. But in true Master Style, he didn’t worry and aggressively started to fuck my face. Holding my throat, I could feel his huge cock and head slide down my throat and with each thrust he hit the back of my throat causing me to gag. Not concerned with my comfort, Sir continued his assault on my mouth faster and faster, his balls slapping against my face and the pressure of his hands on my throat causing my to slowly turn blue.

After 10, maybe 15 minutes of non-stop abuse, I could finally feel his cock starting to grow in my mouth. A first shot of cum fired straight down throat into my stomach, immediately followed by a second. A third shot landed just at the back of my throat and I could just about taste the salty liquid. A fourth shot fired straight in the back of my mouth, followed by an avalanche of cum. Shot after shot hit my mouth and tongue, until my mouth was overflowing and the shots started to cover my face.

When the flow of cum had subsided, Sir grabbed my face, forcing my mouth shut. “Now swallow, bitch!”

I had no choice but to obey, unable to fight if I wanted to. I happily swallowed to load and enjoyed the feeling of cum drying on my face, my own locked cock dripping as it dangled upside down.

“Good boi.”

“Now I think it’s time to discuss what further changes we want to make?”

I gulped, still dangling somewhat upside down. Master started to move the wheel up until I was up right again, with sweet and caring smile on his face.

“Now I think you may have been a bit surprised by the extent of your transformations this week. What do you think of it?” He sounded genuinely interested in my thoughts and I was keen to share my feelings as I had not had the chance to talk to anyone about all the changes.

“At first,” I started, “I really didn’t like it. I struggled with the size of these tits and thought they looked ridiculous. But during the week I learnt how amazing the felt, the energy, the strength they have. And it seemed as though more men and women were lusting after me than ever before.”

“I would hope so. They’re gorgeous. How big do you think they are now?”

“I dunno I haven’t measured them.”

“I estimate they’re maybe an E cup. Really quite big!”

I nodded and continued, “I think they’re about right now though. Maybe a bit bigger.” It was out before I knew it. I really wasn’t sure if I wanted them to grow further, but apparently my mouth had decided for me.

Master smiled. “Oh really? Do we need to get you an actual bra as well then?” He said with a more wicked smile on his face.

“What? No!?” I said both confused and somewhat outraged.

“Haha,” he laughed, “Don’t worry. You’re my slave and boi. Which means you’re a man. Just a man with solid muscle tits. What else would you want to grow then?”

I considered this for a moment. I didn’t really know. I really liked the proportions my body had at the moment.

Master must have noticed my doubts.

“I think there are just a few minor adjustments to make. First, I think we should make your butt more bubbly. Just a bit bigger to say to guys—’this cunt needs filling’. Secondly we can make your tits a bit bigger, maybe a G or H cup, and also just tweak all your muscles a bit. I have developed one mixture that perfectly preserves proportions but makes everything a bit bigger, and you taller, and I have one that maximises definition.”

I thought for a moment.

“Do I have a choice?” I asked him first.

“Yes you do. Although if you refuse one there will be a punishment.”

“What would the punishment be Sir?”

He thought for a second. “I suppose I can tell you as it may influence your decision. For each mixture you refuse you are not allowed to cum for one additional month.”

I gulped. I had been joking about refusing any. All of them sounded amazing.

“I will gladly do the ones you have just mentioned Sir.” I carefully considered my phrasing, not wanting to commit to any he hadn’t mentioned by accident.

And with that Master simply smiled and went to work. He brought in a small table that stood in front of me as I hung on the bondage wheel. He removed the chastity and inserted the needles and attached saline bag.

“It’s pre-mixed,” he explained. “I thought you might not refuse.” And with that he walked out of the room, switching off the light, leaving me in the darkness.

I could feel my balls get heavier. In the darkness, unable to move, I fantasised of the body I would get once this was over. But nothing was able to prepare me for the results.

Unlike the first time I had been subjected to saline in this room, I stayed awake the entire time, completely aware of my increasingly heavy balls and cock. It must have been after about an hour that the light switched back on and Master checked in on me.

The bag of saline was empty and now fully unloaded into my balls. And god had they grown. They were so big that I could see the tip of my cock over the edge of my tits. The thick, swollen cock resting on top of huge balls, perhaps the size of bowling balls.

I audibly gasped as I saw how big they had become.

“Hehe, you like them, boi?”

“Fuck, that will reduce in size, surely?”

“Of course, it’ll go back to your previous size. Although the other solutions we have used are absorbed quickly, this one will take a bit longer. Your balls should be back to normal size on Monday morning but the full body growth will only be done by that evening.”

I nodded to acknowledge I understood.

“So that leaves us the rest of the weekend.”

He smiled and I felt my swollen cock twitch. Master moved to release me from the wheel and gently helped me down.

“Time to get you dressed to go out, boi.”

He must have noticed I looked confused. Where would we be going with me looking like this…

“It’s only 11pm on a Friday night. I am sure we can go to a nice gay bar somewhere in town.”

My heart skipped a beat. I was not excited by that idea whatsoever. “Fuck” was all I could whisper in response.

“Come on boi, no need to be worried. Master will take care of you.”

He took my hand and led me to another room. I realised I had only ever seen the hallway, the staircase and the bondage room, but this room was beautiful decorated with a modern bed, two comfy chairs and a 50” television. But Master took me straight into the walk-in closet.

There, I saw the biggest collection of fetish wear I had ever seen in my life. A range of leather harnesses, chaps, gimp suits, as well as various items of sports gear. Master selected a couple of items and passed them to me.

“Put these on boi.”

I obeyed. The first item was a pair of black neoprene shorts.

“I got these custom made for you,” he said with a slight smile.

I slid them on, feeling the tight neoprene stretching over my big thighs, with the fabric line just above my knee. I first put them on, feeling the fabric cover my butt before trying to tuck in my huge saline inflated balls. With a bit of manoeuvring and effort I eventually manage to get them to stay in the shorts.

I looked down, the bulge was obscene. No one would ever believe that wasn’t a bulge full of fake cock or a tonne of socks.

“Here is a harness.”

Master gave me a stretchy feeling black neoprene harness. Immediately I obeyed and felt the fabric stretch across my huge tit pecs.

“The items you’re wearing are designed to be able stretch as you grow during the weekend so you don’t have to take them off.”

I nodded to signal I understood.

“Oh, and I may have some friends that wanna pump your cunt tonight. You can’t refuse. I haven’t helped any of them get muscular but I have made sure they have nice big cocks, so you better feed on their cum boi. They have to say ‘Master, Michael said it was my turn’, understood?”

I nodded again. Now there was something I was good at.

And with just a pair of leather boots and a collar added we walked out of the door, taking a cab into town. We found one of the raunchier gay bars where I seemed to fit in just fine. At least in terms of what I was wearing. My body on the other hand, stood out. Everyone I walked past stared at me. Some were looking at my huge tits, others preferred to look at my huge bulge. Yet others chose my growing ass, with plenty of guys grabbing it, squeezing it and just generally feeling me up.

And I? I loved the attention. With each grab I could feel my hole or cock twitch. With each stare at my pecs I casually bounced my tits slightly, and with each look in my direction I subtly flexed my biceps just to let them know that I knew they were looking.

I was in heaven. The crowd loved my new form and they wanted me. I was the centre of attention and I didn’t want it to stop. Master attached a leash to my collar and dragged me around the club, allowing men to worship my body. Each hour I could notice my bulge getting slightly smaller as my ass and tits grew bigger and bigger. And every minute of every hour men were sucking on my huge nipples, licking the crevice between my tits and worshipping the veins on my biceps.

Everyone seemed to bring me drinks, and drinking I did. My newly huge body took much longer than my old body to get drunk but after two hours of never having an empty glass I was completely wasted, and with some of the drinks perhaps a little spiked, I was also slightly high. I felt euphoric, alive and excited.

At about 3am I felt a strong tug on my leash. Master had been with me most of the way but now I saw it wasn’t him holding the leash. It was a young guy. In fact, it was a very young guy. He can’t have been older than 19. He was very cute, with dark brown hair, but radiant blue eyes. He pulled me towards his face, leaning into my ears and whispered “Master, Michael said it was my turn.”

And with that he tugged the leash hard, forcing me down on my knees. He pulled me away from the crowd as I crawled through the busy nightclub into a secluded room at the back.

I could sense other guys were following but this twink didn’t care. Once in the corner of the darkroom he unzipped his jeans and whipped out his big cock.

Master had not been joking. He had helped the guys here to grow their cocks. I watched in amazement as he unfolded his cock, and saw at least 9 inches of soft cock dangle in front of me. Master had impressed me with his cock and had spoiled me with my own, but this twink was something else. He may not have been as long as master or myself, but he was thicker than his own wrist and his head stood as a big mushroom on top of his flaccid dick.

“Go on then boi.”

I opened my mouth and without warning he rammed all 9 soft inches down my throat. I gagged immediately but breathed in through my nose as I tried to relax. My throat adjusted and I could feel his dick start to grow down the back of my throat. After just a few seconds he started to fuck my face, but holding me tightly in place.

I was surprised by his strength and the force he was able to exert over me. Not that he needed to, Master had given clear orders to service the men and I was keen to accept his load down my throat. Or ass. Whatever he decided.

I could feel the guys gather around me. I remember the phrase Master had told me to make sure not every guy in the club made use of me.

The twink pulled the leash hard, forcing me to stand up. I looked a bit confused, having loved every second of the throat fuck. But without waiting long he turned me around, took out a packet of lube and within minutes started to fuck me through the zip in the shorts. The head of his huge cock rammed into prostate as a guy whispered “Master Michael said it was my turn”. I obeyed and bent down to start sucking on his dick. It too was big, although not nearly as big as the twink’s dick. But this stud was a beautifully toned young jock and eagerly fucked my face hard.

The darkroom was clearly full of guys watching my huge body get fucked roughly at both ends. Choking hard on one side, while my prostate was getting hammered harder on the other. The silhouette must have looked incredible with two huge cocks invading both holes. From the corner of my eyes I could see guys jerking their cocks, most of them just average sized, but a few are hung like horses. Suddenly the hung twink sped up his pace and within seconds I could feel my ass flood with his cum as the young jock unleashed a torrent of cum in my mouth.

Within a moment the next guy whispered Master’s phrase in my ear and invaded my ass while another invades my mouth. Neither of them disappointed in size as another set of hung hunks started to fuck me hard.

And so the evening seemed to go on for a quite a long time. It was mostly a blur as cock after cock fucked me and dumped their load in me. I dunno how many guys master helped grow their dicks but God it felt incredible.

The entire time my cock was rock hard, cum dripping through the neoprene shorts as my balls steadily got a bit smaller.

I wasn’t sure when Master led me out of the darkroom and into his truck, or when we got home. I just remember waking up the next morning in his arms, my huge muscled tits lifting the sheets up high. My balls still inflated and I could feel a huge plug back in my ass. And that was only Friday night, who knows what the rest of the weekend would bring.

When I awoke in the morning I still felt a bit drowsy. I could feel my arse plugged and my genitals still felt massively inflated. I stirred and Master moved next to me too.

I wanted to be a good boi and so decided to suck Master as he slowly woke up. I could feel him slowly get hard in my mouth as I passionately sucked his big ginger cock.

“Oh that’s a good boi,” I heard Master say after a few moments. “Glad to see you know where your place is, boi.”

I kept sucking him for a while, my head under the covers, taking my time to swallow the entire shaft down my throat. After a while I could feel his cock spasm and as I took it deep I could feel his balls draining into my stomach.

With the energy from Master’s morning cum I jumped up, excited to see Master with a smile on his face.

“That’s a good boi!” He tugged on my collar and kissed me deeply. “Now go make some breakfast.”

I gladly obliged, being very hungry myself. “Can I have some too Sir?” I asked.

“Of course boi. In a bowl from the floor.”

I hung my head, humiliated but accepting my fate.

I went to work in the kitchen, cooking up a full fried breakfast for Master, my huge muscle tits, bubble butt, and salined cock bouncing about as I did.

We spent most of the morning being surprisingly lazy. We hung on the sofa and watched some TV as I obediently sat at Master’s feet. Occasionally I would get him something to drink or anything he needed really.

After lunch Master took me into a room I hadn’t previously been in. It turned out the house had a gym.

“I want you to pose boi.”

“Sorry Sir?”

“Like a bodybuilder. I want you to show off your muscles.”

“Okay.”

I moved towards the large mirrors at one end of the room.

“You will have to wear this boi.”

Master handed me a tight fighting blue posing suit. Well, it looked like more of a thong. There was more fabric at the front to accommodate my humongous cock than at the back to cover my huge ass.

I put it on obediently and looked at myself in the mirror. I kind of looked ridiculous, and yet I looked magnificent. It was clear I had already started to grow a bit in height, and the increased definition and my muscles seemed to have grown proportionately. And my tits and ass had been growing since last night, in the club. Although I noticed the fabric at the back didn’t even fully cover the butt-plug…

Without even thinking much about it, I started to flex, showing off individual muscle groups as well as I could without thinking about it.

Master was standing close by, admiring the body he had been sculpting. His cock clearly straining in his shorts. I saw him smile and occasionally he would correct a pose, telling me to lift my arm further, or concentrate harder on the flex.

After a while he started to give me a set order, making me do it over and over again, like he was getting me to develop a posing routine. We must have worked on it for a couple of hours but towards the end I had memorised it completely, as I had done it so many times.

I made dinner again, the same way I had made breakfast, and the same way I would make many a meal for him to come. Master made sure to portion some out in a bowl on the floor for me to eat and I eagerly ate it all. Thankfully I was a good chef.

After dinner Master took me to the side and handed me another pair of posing trunks, these ones bright red. This one seemed smaller than the last and my body really seemed to pop out of it, accentuating every muscle, every crevice and every vein on my body.

“You’re going to show off tonight for a few of my friends, slave.”

I just nodded, knowing full well what would be in store.

What I didn’t anticipate was that I would be stored before the event. Master opened a cupboard in the living room I hadn’t seen open before. And for good reason.

A sliding door revealed the metal bars of a cage, which turned out to be a door that, when opened, revealed metal shackles dangling from its walls and resting on the floor.

“Get in, boi.” I was kind of scared, but Master wasn’t having it. “I gave you an order and I expect you to follow it,” he said.

“Yes, Sir.”

I complied and did as I was told. Master put my wrists in the shackles above my head, and my ankles in the shackles on the floor. And there I stood, spread eagled, my huge bulge on show in the tiny posers and my muscles still growing. Master closed the cage door first and locked it, before closing the sliding door to hide me altogether.

I could feel my heart beating in my chest as I waited. A hint of light shone through the bottom of the door but otherwise I could see little.

It seemed to take ages before I heard anything else. I waited, half aroused, half scared to see what was to come.

Eventually the door bell rang and I could hear master talk to the guests. I couldn’t hear everything they were saying but I heard small bits.

I got confused. I heard things like “…bigger for the night…” and “I want to see how much he…”

The doorbell rang over twenty times. Actually a lot more. I tried to count but eventually I got too confused. The men all went into a different room as I stood there.

Eventually the voices came from elsewhere in the house and people gathered in the living room. Just outside the cupboard cage there were people talking and socialising.

Suddenly, without much warning, the door started to slide open. A small motor was sliding the door across as it slowly exposed me. Not all the men noticed immediately, instead continuing their conversations.

But a few people noticed, and then silence seemed to spread around the room like wild fire. By the time the door was fully open, master stood beside me, and I noticed a big smile on his face. “Guys, gather round,” he called to them.

Instantly he had everyone’s attention and the men gathered round, swapping looks between Master and myself. I stood there, proud to display my huge morphed body.

I could see boners in people’s trousers. And they were huge hard-ons. Every single one looked oversized and massive. The sight made my own cock stir in the tiny posers.

“So, I know you have all just had the pleasure of experiencing a bit of the treatment that has made this slave here possible.” Master pointed at me and smiled. “He is here to service your needs. As his balls are still full of saline mixture, feeding him cum in both his ass and mouth will further enhance his growth, so he can truly reach his full potential.”

He gestured toward me as if I were an exhibit. “I’m proud of what I and my slave have created,” he said. “I hope you enjoy him in a little while. But first, keep drinking and socialising, and feel free to slowly dress down.”

I remained on display as the guests went back to their earlier conversations. One guy had already taken the last message to heart and took of his t-shirt, revealing a tight and smooth chest, with a perfect six pack and pecs. A black and white leather harness emphasised his muscles beautifully,

The other men mostly kept talking but once in a while one of them took of their shirt. Occasionally a group would come up to the cage and admire me, but none tried to touch me. I wondered if Master had told them not to touch while I was in the cage.

Once in a while I spotted Master speaking to group of men. Once in a while pointing at me and having a huge smile on his face. He looked proud. And he definitely made me feel it.

The entire time I was getting hornier and hornier. The sight of the hot men, topless in various fetish gear, made me cock twitch but the tight lycra acted as a chastity cage.

Eventually the men started to strip off their trousers too, revealing jockstraps and boxers, as well as a few leather, rubber and neoprene shorts and pants. Every single one bulging with a huge cock. Master himself revealed a tight lycra singlet, leaving little too the imagination. He walked up to the cage and smiled at me.

“Do you like it?” he asked.

All I could do was dry fuck the air with my hips, to the extent I could move them at all. He laughed. “I thought as much, looks like you’re struggling in those posers.”

I simply nodded.

“Well, you’ll be even more excited to hear that I have an extra special treat. You see all those huge bulges in their underwear?”

I nodded again.

“Their cocks are huge now. And they’re only soft, or maybe semi-erect. But when they get hard, they’ll get even bigger. You see, I gave them a speed dose of the saline that will ensure their cocks are at least 9 inches. But for the next 12 hours, that minimum is increased by another 7 inches. Usually a 16-inch cock is too big for most guys to take. But you can do that easily.”

With that he stuck his hand into the cage and squeezed my nipples hard.

I moaned, my cock again twitching in the posing strap.

“Now one more thing,” he said. “I used the speed dose too—just the temporary increase, understand. And my cock was already 15 inches.” With that a wide smile appeared on his face. It was going to be a painful, but hopefully fun, 12 hours…

I stood there for a little longer, relishing being on display.

It probably took another half an hour before the cage door automatically opened, but the shackles remained in place. Now everyone seemed to walk up and touch me, feeling my rock hard abs, my strong thighs, my bulging biceps but most of all my huge muscle tits. And they continuously complimented me.

“Those tits are amazing boi.”

“That body is incredible, and those boobs.”

“I wish my wife had tits like that.”

“I hope his pussy is as good as those tits.”

Man after man felt me up, touching, rubbing and squeezing my body. I got hornier and hornier as the men touched my intense masculinity, admiring every crevice, every vain and every muscle on me.

Eventually master looked at me. “I think it’s time don’t you?” he said. I just nodded.

With that the shackles un-clicked and my arms dropped. I regained my composure quickly and stood there, awaiting instructions.

Master took my hand and guided me out of the cage and onto the living room floor. The men around me looked at me, admiring my huge body, with their own boners waiting.

Master helped me onto a small table in front of the cage, just to position me higher up than the gathering crowd.

“Do the routine boi.”

And with that I started to flex. I really took my time, fully concentrating on each move, each flex. My veins were popping and my muscles had never looked this good before.

The crowds were cheering me on. When I did the most muscular pose everyone went wild, wolf whistling and shouting with excitement. I even saw some guys jerking off.

When it was over Master took me over to the middle of a room, out of sight of the cage where there was a sort of bondage device I hadn’t seen before. It was a sort of bench, covered in leather, with restraints at either end.

Master simply said: “Bend over on the bench boi.”

Of course I did as was I was told and climbed onto the bench, hands at one end, which were swiftly tied down. In the middle was a hook that locked straight onto my collar. Once my feet were tied down too I was hardly able to move, just forced to present my ass high in the air, waiting for cocks.

“Right, guys,” Master said loudly, “it’s time to use the boi. I will go first, and everyone will get at least one go after. The rules are simple, you must fuck until you cum and dump your load inside him. Each load he takes will encourage his further growth and by tomorrow morning his balls will be significantly more empty but his body should be significantly bigger.

“Most of your loads will just go to making his body bigger overall, but if you do wish to grow a specific body part, like his ass, or tits, you can take one of the supplements about 5 minutes before you start to fuck. There is a limited number to ensure they don’t grow insanely huge but enough to make a difference. Now …is everyone ready?”

A loud chorus of yes echoed through the room and Master grabbed some lube. He pulled the singlet down to his waist and revealed his huge cock.

It must have been 15 inches soft, more powerful and bigger than I could have dreamed of. I was kind of happy he was going first, it means no dick would be bigger than his, the most difficult would be first.

He pulled down the posing strap, leaving it around my thighs and lubed up my hole, which twitched as it anticipated the invasion. I heard him lube up his cock and after a short moment I could feel the huge head at my cunt. He pressed carefully. I had no idea how big his hard cock was but the feeling that ensued was the most painful and yet pleasurable feeling I had ever experienced. Slowly the huge tool invaded me, pushing anything and everything away and making me scream in agony.

The pain was almost too much and I kept screaming and screaming at the top of my lungs, until someone forced a gag into my mouth. I must have taken a long time but eventually I could feel Master’s balls gently hitting mine.

And that’s when it really started. Master pulled almost all the way out before slamming it straight back in again. I screamed into the gag, the pain was just too intense.

He fucked me for what seemed ages. After a little while the pain went away leaving only intense pleasure. Shivers went from the base of my cock up to my tits and from the top of my back all the way to the point where Master hit my prostate.

And that’s how he fucked me. Me tied up to the bench, with my head locked into place and my huge tits cushioning me. The men around me were cheering as I was getting fucked, jacking their own cocks as they witnessed the destruction of my hole.

Eventually Master seemed to get close to the end. I felt his cock spasm and after a few more strokes I could even feel his load shoot straight into my ass, with floods of cum being left inside me.

After this I was free game. Various men started to invade both my mouth and cunt. Fucking me hard, slamming my prostate and using me.

None of the guys came too close to the size of master’s cock. He had truly opened me up and ensured my hole would be gaping for the of the evening. I heard guys grabbing the special mixtures to encourage specific growth and fucking me mercilessly.

And me? I loved every second of it. Never had I had so much pleasure and lust in one evening.

At one point in the evening the chavviest of twinks walked up to me, with a huge 19” cock dangling between his legs.

“You want this boi?” he asked.

I simply nodded and with that he placed the cock head at my mouth. Meanwhile someone was still pounding my ass hard as I tried and expand my throat to accommodate his huge cock.

With every second that passed he was able to push his cock in further and further as I felt my throat readjust to deal with the immensity of his chav cock. I looked up and could just about see his beautifully toned body move as he fucked my face. I could feel my own cock leak down the bench as a load many days old built up.

The last few slams on my ass meant the top was done and the chav would be next.

Within seconds his dick left my mouth and entered my ass. Unlike the guys so far he didn’t hesitate and slammed his cock straight into my cunt, and started to fuck me mercilessly. Around me guys were applauding and cheering as he went to town on my arse, pounding me mercilessly and brutally. I could feel my insides being rearranged as he fucked me harder and harder, each stroke sending waves of pleasure to places I didn’t know existed.

And so the night progressed further. On my right I started to notice a blackboard. With tally marks on them. So far I noticed 12. I guess that means that 12 guys have fucked me.

As the video of the night would later show, as man after man, cock after cock, morphed tool after morphed tool fucked me brutally, mercilessly and hard, my body grew. With each stroke my bicep increased just enough to see it with the visible eye, with each slam my body seemed to move just a bit as my pecs grew bigger.

But in the moment, as I was drowned in lust and cum and men and I didn’t notice. Occasionally I heard a cheer and suspect that maybe my body has hit a new milestone but my mind was spinning as I struggled to even comprehend what was going on.

I think I passed out. No one noticed as I continued to respond to requests to suck cock and my ass obliged with each cock that invades. The next time I looked at the blackboard I saw 29 tally marks.

How I was able to sleep with so many men in the room, so many cocks in my ass I didn’t know but I did. And indeed the next time I woke up the room was deserted.

My entire body was sore, each muscle aching and my cunt, mouth and throat thoroughly used. I could feel my cunt wasn’t empty as a big plug had ensured every load dumped in me the evening before was still in.

I was still tied up though, unable to move. I felt my heart beat and a slight shiver across my back. I tried to look around but even my collar was still attached.

I am not sure how long I sat there for. My body ached and I was desperate to be released.

At some point I noticed light creeping in through the curtains as the sun started to rise. I could just make out the number 42 on the tally…

Eventually I heard some footsteps. It was the chav twink who had fucked me so brutally during the night.

“I see the bitch is awake,” he said with a sense of triumph. “I should use my cock while it’s still at this size.”

He removed the plug and swiftly forced his huge tool into my ass, which was still plenty stretched and had no issues taking it. He was more gentle than earlier, maybe it was because he was tired or maybe he had been a bit overenthusiastic the evening before, but regardless this fuck felt a lot more relaxed than the one the previous evening.

In the middle of this, I heard another set of footsteps and this time Master appeared. I could see him smile from the corner of my eyes as the twink continued to fuck me, encouraged by the sight of Master. Eventually he dumped his load and Master took it as the cue to unhook my head and quickly undid the restraints. And of course he replaced the buttplug.

I hadn’t moved all evening and Master quickly grabbed me in both arms and carried me to his bedroom where he laid me in bed.

“Well done boi. Really well done, I’m so proud of you.”

“Thanks, Master.”

I noticed my balls were mostly empty now, with only just a bit of saline remaining.

“You’ve completed most of the transformation. Have some sleep and we’ll see what it’s like when you wake back up.”

And with that he tucked me into bed and I fell asleep immediately.

A few hours later I woke up. Not because I wanted to, or because I was well rested but because Master had shoved his big cock in my cunt.

“I thought that would wake you up,” he said with a wicked smile.

He didn’t stop pounding me and my already stretched arse eagerly took every inch of his huge cock. It felt as though his huge cock hadn’t lost its temporary size yet and indeed when I looked down I could see my abs bulging. I moaned as he fucked me, this size of cock definitely being a bit big for what I was used to.

And so he fucked me for quite a while. Destroying me one last time before he’d go back to normal size. The feeling was incredible and with each stroke I felt a shiver going down my spine. My own cock was dripping pre and I couldn’t wait to get some release myself at some point.

Eventually I felt Master’s cock explode, violently erupting inside me and once more filling me with his seed.

“Good boi,” he said as he replaced the plug once more.

He got up as I laid there, somewhat spent. I heard him rummage around and eventually he got back with a massive chastity cage. He smiled.

“Just for the last time I think boi. But hopefully this will fit. And then we’ll get up and measure you.”

He noticed my cock was still hard from the fucking he had just given me.

“Hmm that’s a problem.” Without warning he punched me in the guts. And although I had developed a very solid eight pack it still hurt. He punched again.

My cock quickly went soft.

Master slipped on the cage and smiled. “Sorry, but I had to get it down.” I just smiled faintly. I had actually been kind of hot.

“Now—time for your final size!” Master led me down into the gym where he made me stand in front of the mirror.

I audibly gasped.

“Hehe that’s right boi! You’re no longer small anymore.”

I wasn’t. I really fucking wasn’t. I was bigger than Master by a long stretch. My eyes were immediately drawn to my tits, which were even bigger than last time, and even more out of proportion. Everything about me screamed huge. My biceps must’ve been the size of bowling balls, and my abs had grown into an actual 10 pack! I looked incredible. I started to repeat the flexing routing master had taught me just the day before.

Master smiled, he looked incredibly proud.

“The world is going to love you, boi.”

“So what’s next Master?” I asked him.

“Well, your growth is done. You’ve done everything I wanted you to do and more. You’re the creation of myself and over 40 loads of cum. You have given me a real reason to be proud.”

“But Sir—I mean. It is isn’t over is it?”

“What do you mean?”

“I mean, I will still keep serving you, won’t I?”

“Uhm. Well I have to admit I didn’t think you would want to. Do you want to?”

“Yes Sir. These last few weeks have been the best in my life. You helped give me purpose. I want to keep serving you Sir until there is nothing left to serve.”

“Oh, well, in that case…” Master hesitated. I wasn’t sure what was going on in his head. It felt as though he hadn’t expected this at all. “I had hoped to just keep growing boys like you.”

“Oh… okay….” I looked visibly upset. I had definitely expected to stick around.

“But, hold on,” he said quickly. I could see his mind was racing. “We could do it together. You continue to be my slave and help me find guys who want to grow. The relationship we’d have would not be exclusive, but it would be about us both having pleasure. I will continue to use you and organise things like this weekend if you like…” He paused for a moment, as if waiting for an answer.

“Uhm… fuck yes!” I said enthusiastically.

“And then we can pick out guys to grow together. We can use your incredible body as bait and find the guys who ‘wish to have a body like you’ and grow them to be a perfect pack?”

I nodded enthusiastically.

“Would you really be up for that?” I asked him seriously. “I wouldn’t want to cramp your style.”

“Are you kidding me? The last few weeks have been incredible for me too! I could do this over and over, but I could never do it all by myself.”

“Can we just agree that I will always be the biggest?” I asked him, quite seriously.

“Yes. Yes, we can. But I think we will have to keep pushing the boundaries on that. Once in a while we’re going to create someone bigger than you, but we’ll quickly make up for it and grow you again.”

“Okay, I can live with that.” I didn’t say how much I would love to grow again but this seemed a perfect solution.

“Just remember you still have to go to your job, though!”

“Of course! If they want me back looking like this.”

“Don’t worry. The substance is set up in such a way that your growth, although noticed by those in your surroundings, isn’t considered outrageous. And you don’t even need to buy new clothes.”

And with that he put a leash on my collar and took me back to bedroom.

“So,” he said, “is there anyone you’d like to grow first?”

I smiled. “If he wants, there is actually. The cute chav that you found fucking me this morning.”

“Oh, he is so keen for it. When he saw your body he almost nutted right there. But he is quite a dominant guy. We’ll have to tame him.”

“That sounds fun. Either he obeys, or he doesn’t grow. I reckon we both know which he’ll choose.”

As I said those words, Master forced me on my knees and I took his once again hardening cock deep into my throat. Without hesitation he began to fuck my throat and I could feel my own cock twitch.

He threw me on the bed, me on my knees. He grabbed the keys and unlocked me.

“I think it’s time for you to come.”

For one last time that weekend, but definitely not the last time in our life together, he shoved his huge cock into my lose cunt. Balls deep immediately. Standing over the edge of the bed he grabbed my neck with this strong hands as I sat there on my knees, my ass just over the edge.

As he fucked me I could feel my cock getting harder and harder. It rapidly grew into its magnificent new length. It must have been over 15 inches long when I finally felt like it was rock hard.

After a few more thrusts Master threw me onto my back, quickly shoving his cock back in as he started to jerk me off. I wasn’t going to hold out for long and indeed within minutes I could feel my own balls twitch, ready to erupt.

And that’s all it took for me to cum after weeks of stimulation. My balls twitched, my cock pulled and a fountain of cum erupted. Stream after stream of cum shot out into the air hitting Master in the face, hitting me in the face. I must have gone on for a good few minutes and by the end of it I was drenched in the biggest load of cum I had ever shot.

Master smiled and kissed me, dragging me to the shower on the leash where I eagerly washed myself and Master.

And that is the story of how I met Master. We still live together, growing boys into men. And that chavy twink? He was the first to grow and actually came to live with us too. But how that happened is another story.
